  • 00:00:00
    hello to all deer in clean energy
  • 00:00:02
    enthusiasts
  • 00:00:04
    welcome to fixed Focus program hope you
  • 00:00:07
    all are doing well wherever you are
  • 00:00:11
    today I want to start building a larger
  • 00:00:13
    solar dish for the fixed Focus system
  • 00:00:16
    although this solar dish is small we did
  • 00:00:19
    various tests on it
  • 00:00:21
    the surface of this solar dish is less
  • 00:00:23
    than one square meter and we will change
  • 00:00:25
    this dish in future plans
  • 00:00:29
    and for this we need to make changes to
  • 00:00:31
    the system
  • 00:00:33
    if we choose a bigger solar dish the
  • 00:00:36
    tests can be done better and easier
  • 00:00:39
    so in this program we want to start
  • 00:00:41
    making a square dish
  • 00:00:44
    circular dishes do not have corners and
  • 00:00:46
    this park has been removed
  • 00:00:49
    so we want to have a square dish to use
  • 00:00:51
    the maximum system surface and not waste
  • 00:00:53
    energy
  • 00:00:55
    in the fixed Focus system the path of
  • 00:00:58
    the solar dish can accommodate a square
  • 00:01:00
    dish in this figure you can see that the
  • 00:01:03
    energy concentrated in a square dish is
  • 00:01:05
    approximately 1.27 times the equivalent
  • 00:01:08
    circular dish of course not every type
  • 00:01:12
    of dish can be mounted on this system
  • 00:01:13
    and it must have its own specifications
  • 00:01:17
    for example it should have a Groove for
  • 00:01:19
    the focus base and edges as a central
  • 00:01:22
    support
  • 00:01:24
    of course we should make a dish that can
  • 00:01:26
    work for us for at least 15 years
  • 00:01:31
    however this work is a difficult task
  • 00:01:34
    especially in Winter and in this cold
  • 00:01:36
    and rainy weather and if you want to do
  • 00:01:38
    this work you must not forget to be
  • 00:01:40
    careful in your work in addition we can
  • 00:01:42
    also use solar flat dishes and it is
  • 00:01:45
    relatively easier to make but the main
  • 00:01:47
    problem of flat dishes is that it is not
  • 00:01:49
    possible to wash its surface easily and
  • 00:01:51
    I plan to make a solar dish with a
  • 00:01:53
    surface of 1.6 by 1.6 meters in which
  • 00:01:57
    case its area will be 2.56 square meters
  • 00:02:00
    of course I made the design for a three
  • 00:02:03
    meter dish the length of one side of
  • 00:02:06
    which is 1.8 meters but due to the need
  • 00:02:08
    for many system changes I reduced its
  • 00:02:11
    length to 1.6 meter in this figure we
  • 00:02:14
    have a dish with a side of 1.8 meters
  • 00:02:16
    which is a part of a sphere with a
  • 00:02:18
    diameter of 4 meters
  • 00:02:21
    this figure shows the central
  • 00:02:23
    cross-section of the sphere shown as a
  • 00:02:25
    circle
  • 00:02:28
    if you look carefully at the figure you
  • 00:02:30
    will notice the calculation and Design
  • 00:02:34
    making this type of dish is not an easy
  • 00:02:37
    task because it requires both precision
  • 00:02:39
    and patience
  • 00:02:41
    those who want to prepare a solar dish
  • 00:02:43
    with this method should watch this video
  • 00:02:45
    carefully
  • 00:02:48
    so first we have to find a suitable
  • 00:02:50
    environment for this work
  • 00:02:54
    are you ready to go to start a tough
  • 00:02:56
    work
  • 00:03:00
    well now I have prepared an environment
  • 00:03:02
    for making the solar dish mold
  • 00:03:05
    the width and length of this space is
  • 00:03:07
    almost suitable and if it is bigger it
  • 00:03:09
    is much better
  • 00:03:11
    [Music]
  • 00:03:12
    I put a plastic under the work so that
  • 00:03:14
    it can be collected easily if the
  • 00:03:16
    plaster spills
  • 00:03:18
    [Music]
  • 00:03:24
    to shape the mold of the dish I already
  • 00:03:27
    prepared a tube with the required length
  • 00:03:30
    [Music]
  • 00:03:35
    this metal tube is bent with radius of
  • 00:03:38
    two meters so the focus distance of our
  • 00:03:40
    dish will be one meter
  • 00:03:43
    [Music]
  • 00:03:45
    the distance from this part of the pipe
  • 00:03:47
    to the other end is 2.30 meters
  • 00:03:50
    [Music]
  • 00:03:52
    so we can start working with this metal
  • 00:03:54
    pipe
  • 00:03:56
    [Music]
  • 00:03:59
    first I put on work gloves
  • 00:04:04
    [Music]
  • 00:04:14
    I made an iron base as you can see
  • 00:04:19
    I have placed two bearings in this part
  • 00:04:23
    one is here and one is here
  • 00:04:28
    [Music]
  • 00:04:31
    of course you can weld the threaded rod
  • 00:04:33
    in the center of the tube instead of the
  • 00:04:36
    bearing
  • 00:04:38
    now I place this stand in the center of
  • 00:04:40
    the work environment
  • 00:04:50
    two washers
  • 00:04:51
    and now I put the tube that is pierced
  • 00:04:54
    in the middle on the screw rod
  • 00:04:55
    [Music]
  • 00:05:02
    you can see that the rotation of this
  • 00:05:05
    tube draws a part of a sphere
  • 00:05:07
    sure
  • 00:05:09
    [Music]
  • 00:05:17
    we have to fill the entire part under
  • 00:05:20
    the tube to prepare the mold and the
  • 00:05:22
    volume will be really large
  • 00:05:24
    [Music]
  • 00:05:26
    if we want to use plaster we need a lot
  • 00:05:28
    of plaster
  • 00:05:31
    [Music]
  • 00:05:38
    the first method is to use Foams
  • 00:05:40
    available in the market
  • 00:05:43
    [Music]
  • 00:05:45
    we can cut Foams layer by layer and fill
  • 00:05:48
    the volume
  • 00:05:51
    [Music]
  • 00:06:04
    but the second method is that if you
  • 00:06:06
    have access to a suitable Hill you can
  • 00:06:08
    insert the rod at the top of the hill
  • 00:06:10
    and into it or prepare an artificial
  • 00:06:12
    Hill
  • 00:06:14
    but maybe someone does not have these
  • 00:06:16
    facilities and wants to have a permanent
  • 00:06:18
    format
  • 00:06:24
    figure for understanding
  • 00:06:25
    [Music]
  • 00:06:35
    so we go to the third method and use
  • 00:06:38
    riblath sheet
  • 00:06:41
    [Music]
  • 00:06:44
    it is a rib lath sheet which is both
  • 00:06:46
    cheap and Light
  • 00:06:49
    in fact I want to leave the space under
  • 00:06:51
    the pipe empty
  • 00:06:56
    [Music]
  • 00:06:59
    for this I use a metal ring with a
  • 00:07:01
    proportional radius that is welded to
  • 00:07:03
    the tripod
  • 00:07:06
    the main base should be placed in the
  • 00:07:08
    center of this ring and I will try to
  • 00:07:10
    place the ring in the right place with
  • 00:07:12
    the meter
  • 00:07:14
    [Music]
  • 00:07:20
    it should be noted that most of the
  • 00:07:23
    weight of the mold is on this metal
  • 00:07:24
    Circle and its bases
  • 00:07:26
    [Music]
  • 00:07:29
    therefore it must have adequate strength
  • 00:07:33
    to place the rib lath sheets I made a
  • 00:07:36
    series of metal wires that I welded to
  • 00:07:38
    the center of an iron sheet and put the
  • 00:07:39
    hole in the center on the base these
  • 00:07:42
    wires which are eight in number provide
  • 00:07:44
    a support for placing rib lath sheet
  • 00:07:47
    [Music]
  • 00:07:53
    I fasten the metal plate with a metal
  • 00:07:55
    nut so that it does not move
  • 00:07:58
    foreign
  • 00:08:01
    [Music]
  • 00:08:10
    sheets on it in proper order
  • 00:08:13
    [Music]
  • 00:08:24
    we tie the rib lath sheets to the ring
  • 00:08:26
    with a metal wire
  • 00:08:29
    foreign
  • 00:08:32
    [Music]
  • 00:08:52
    on the rib lath sheets
  • 00:08:55
    but we cannot put the plaster directly
  • 00:08:57
    on the rib lath sheets because it will
  • 00:08:59
    cause the plaster to fall out of its
  • 00:09:01
    holes foreign
  • 00:09:03
    of course it is possible in places where
  • 00:09:06
    several layers of rib lath sheet are on
  • 00:09:08
    top of each other
  • 00:09:09
    [Music]
  • 00:09:10
    this is the first time I want to put
  • 00:09:12
    plaster on riblath sheet
  • 00:09:15
    I saw a method in a movie related to
  • 00:09:17
    suspended ceilings partition that was
  • 00:09:19
    interesting and we will implement it
  • 00:09:22
    first I will put this piece of foam here
  • 00:09:27
    [Music]
  • 00:09:28
    I have prepared some pieces of plastic
  • 00:09:30
    sack and put one of them on the foam now
  • 00:09:32
    I prepare the plaster and put a thin
  • 00:09:34
    layer of plaster on the plastic sack and
  • 00:09:36
    put it slowly on the riblath sheet after
  • 00:09:39
    the plaster dries the plastic sack is
  • 00:09:42
    easily removed I will do one of them and
  • 00:09:45
    see if it can be done
  • 00:09:47
    we put a thin layer of plaster on the
  • 00:09:50
    sack
  • 00:09:51
    [Music]
  • 00:10:06
    it is better if it is watery plaster
  • 00:10:08
    that I need some more
  • 00:10:09
    [Music]
  • 00:10:17
    Construction
  • 00:10:26
    and in this way we place it on the rib
  • 00:10:29
    lat sheet and let the plaster Harden
  • 00:10:34
    [Music]
  • 00:10:45
    thank you
  • 00:10:49
    foreign
  • 00:10:50
    [Music]
  • 00:11:07
    to the original place and continue the
  • 00:11:10
    work
  • 00:11:13
    [Music]
  • 00:11:20
    foreign
  • 00:11:30
    [Music]
  • 00:11:47
    foreign
  • 00:11:49
    [Music]
  • 00:11:54
    foreign
  • 00:11:56
    [Music]
  • 00:12:06

  • 00:12:24
    foreign
  • 00:12:26
    [Music]
  • 00:12:43
    well almost the plaster coating is done
  • 00:12:50
    and now we can do the main plastering
  • 00:12:54
    let's use the bent pipe and do the
  • 00:12:57
    plastering
  • 00:13:00
    let me tell you one thing and that is
  • 00:13:02
    that the plaster we used for the metal
  • 00:13:04
    mesh is a type that hardens very quickly
  • 00:13:07
    and the plaster that we use later is of
  • 00:13:10
    a type that hardens slowly
  • 00:13:13
    [Music]
  • 00:13:17
    of course for the speed of work you can
  • 00:13:19
    also use plaster in both cases which
  • 00:13:22
    hardens very quickly but you must work
  • 00:13:24
    faster
  • 00:13:25
    [Music]
  • 00:13:26
    well let's go to the next step
  • 00:13:30
    before using the bent pipe I want to
  • 00:13:32
    Mark the dimensions of my work with this
  • 00:13:34
    bent iron angle
  • 00:13:37
    I put it on the work and on two sides
  • 00:13:39
    and Mark it with spray paint to
  • 00:13:41
    determine the area of plastering
  • 00:13:42
    [Music]
  • 00:13:52
    well I welded an iron cylinder to a
  • 00:13:55
    washer and with this I want to create a
  • 00:13:57
    support for a better placement of the
  • 00:13:59
    bent pipe
  • 00:14:02
    also this will prevent the plaster from
  • 00:14:05
    hitting the center of the rotation
  • 00:14:16
    [Music]
  • 00:14:20
    so that the plaster does not stick to
  • 00:14:23
    the pipe I have greased the pipe with
  • 00:14:24
    grease
  • 00:14:26
    [Music]
  • 00:14:31
    for easy movement of the iron tube I
  • 00:14:34
    made a hole in one side of it and by
  • 00:14:36
    tying a wire of suitable length you can
  • 00:14:38
    move it easily
  • 00:14:41
    questions
  • 00:14:49
    well let's go to Casting plaster
  • 00:14:53
    try not to make the plaster thick rather
  • 00:14:56
    the plaster should be properly diluted
  • 00:14:58
    so that it can be easily shaped
  • 00:15:05
    in this way that I prepare
  • 00:15:08
    [Music]
  • 00:15:21
    foreign
  • 00:15:26
    [Music]
  • 00:15:36
    be sure to start pouring the plaster
  • 00:15:39
    from the top because it makes the metal
  • 00:15:40
    pipe have a proper support for movement
  • 00:15:45
    let's go to continue working
  • 00:15:46
    [Music]
  • 00:16:09
    thank you
  • 00:16:10

    [Music]
  • 00:18:29
    well the plaster mold work is almost
  • 00:18:32
    finished and there is some Putty work
  • 00:18:34
    that I will do later
  • 00:18:37
    I will open the tube and tell you a few
  • 00:18:40
    things
  • 00:18:41
    [Music]
  • 00:18:47
    the first point is that you should be
  • 00:18:49
    careful that the pipe does not change
  • 00:18:50
    due to the pressure of the movement on
  • 00:18:52
    its bending work
  • 00:18:56
    it means that the pipe should not come
  • 00:18:59
    out of that initial Bend
  • 00:19:01
    [Music]
  • 00:19:02
    to make sure that the bend of the pipe
  • 00:19:04
    has not changed we draw a circle on the
  • 00:19:07
    ground with the radius of the bend of
  • 00:19:08
    the pipe
  • 00:19:11
    then we put the pipe tangent to it to
  • 00:19:13
    make sure that the original Bend of the
  • 00:19:15
    tube has not changed
  • 00:19:20
    as in the figure you see
  • 00:19:22
    [Music]
  • 00:19:28
    the second point is that the change in
  • 00:19:31
    bending occurs more in the central part
  • 00:19:33
    of the pipe that is perforated
  • 00:19:35
    so that this problem does not arise you
  • 00:19:38
    can weld on the pipe from an iron corner
  • 00:19:40
    with a suitable Bend and with this the
  • 00:19:42
    pipe will be more resistant to bending
  • 00:19:44
    place an iron corner on the pipe like
  • 00:19:46
    this and weld it to the pipe and create
  • 00:19:48
    a central hole on the corner
  • 00:19:52
    in this case the metal pipe will have
  • 00:19:54
    more resistance
  • 00:19:57
    another point is that it is better to
  • 00:19:59
    clean the pipe at each stage of
  • 00:20:00
    plastering
  • 00:20:03
    you can easily do this with an iron wire
  • 00:20:08
    like what I do
  • 00:20:11
    [Music]
  • 00:20:13
    and in this case you will see that the
  • 00:20:15
    part under the pipe is completely
  • 00:20:17
    cleaned
  • 00:20:20
    [Music]
  • 00:20:22
    well I'll work on the plaster mold some
  • 00:20:24
    more then let's go to the structure of
  • 00:20:26
    the solar dish
  • 00:20:28
    well now we have completed the plaster
  • 00:20:30
    mold and we need a metal frame for the
  • 00:20:32
    surrounding of the dish
  • 00:20:36
    and it depends on your work but I want
  • 00:20:39
    this dish for a fixed Focus system
  • 00:20:42
    because I want the solar dish to be
  • 00:20:44
    square so its frame consists of four
  • 00:20:46
    iron corner pieces
  • 00:20:49
    the important point is that the bending
  • 00:20:51
    radius of these sides is less than two
  • 00:20:53
    meters
  • 00:20:56
    and has its own calculation
  • 00:20:58
    [Music]
  • 00:21:00
    now if this is a side of this Square
  • 00:21:03
    its bending radius is less than two
  • 00:21:05
    meters and this radius is approximately
  • 00:21:07
    1.83 meters in the figures you see this
  • 00:21:11
    issue is clearly defined
  • 00:21:18
    foreign
  • 00:21:22
    [Music]
  • 00:21:25
    if you look carefully at the figure it
  • 00:21:28
    is completely understandable well I'm
  • 00:21:31
    going to put these sides in the four
  • 00:21:32
    corners
  • 00:21:34
    I will put the camera in a suitable
  • 00:21:36
    place
  • 00:21:39
    [Music]
  • 00:21:54
    because this solar dish is designed for
  • 00:21:57
    a fixed Focus system so a part of the
  • 00:21:59
    dish should be considered to pass the
  • 00:22:01
    focus base
  • 00:22:02
    and this is how I made it
  • 00:22:06
    since this part is in the center of the
  • 00:22:09
    dish it should be bent to a radius of 2
  • 00:22:11
    meters
  • 00:22:13
    and it should be placed here
  • 00:22:17
    [Music]
  • 00:22:19
    between these iron Corners I use small
  • 00:22:22
    and light metal cans and weld them
  • 00:22:24
    together and this makes the dish more
  • 00:22:26
    solid
  • 00:22:28
    unfortunately the time of the video has
  • 00:22:31
    increased more than usual and the most
  • 00:22:33
    difficult part of making the solar dish
  • 00:22:34
    is done
  • 00:22:36
    and so you will see the second part in
  • 00:22:38
    the upcoming program so goodbye until
  • 00:22:41
    the next program
  • 00:22:42
