[0002] A photovoltaic bracket, also known as a solar panel bracket, is an important component in a photovoltaic power generation system. It is mainly used to install and support solar panels, and according to the specific geographical location, climate, and solar resource conditions of the construction of the photovoltaic power generation system, the photovoltaic modules are arranged and fixed at a certain orientation and angle with a fixed spacing.

[0003] When the photovoltaic bracket supports the photovoltaic panel, since the photovoltaic panel will generate high temperature under solar radiation, the components such as wires and pipelines under the panel are also likely to be affected. And during daily photovoltaic power generation, if it encounters rainy or snowy weather, these components are easily eroded by moisture, thereby affecting the normal operation of the photovoltaic power generation system. Therefore, it is necessary to lay a waterproof film on the surface of the bracket.

[0004] Currently, under the same lighting conditions, the more photovoltaic panels there are, the more solar energy can be absorbed, and thus the higher the conversion efficiency into electrical energy. This makes the placement of photovoltaic brackets very dense, resulting in greater difficulty in laying the waterproof film, and the laying of the waterproof film is time-consuming and laborious. Therefore, it is necessary to improve and optimize it. Content of the Utility Model

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] As Figures 1 to 8 shown, the utility model provides an automatic film laying device for a photovoltaic support, which includes a photovoltaic support 1 and a photovoltaic panel 2. The photovoltaic panel 2 is fixedly installed at the top of the photovoltaic support 1. Moving sliders 3 are movably installed on the front and rear sides of the photovoltaic support 1, and a housing 4 is fixedly installed between the two groups of moving sliders 3;

[0029] A film laying roller 9 is rotatably installed inside the housing 4. Fixed blocks 10 are fixedly installed on the front and rear sides inside the housing 4. A connecting rod 11 is rotatably installed inside the fixed block 10. One end of the connecting rod 11 is fixedly installed with a first baffle 12. A second baffle 13 is fixedly installed inside the fixed block 10. The second baffle 13 and the first baffle 12 are elastically connected by an arc-shaped spring 14. A pressing roller 15 is rotatably installed between the two groups of connecting rods 11, and the pressing roller 15 abuts against the photovoltaic panel 2.

[0030] When it is necessary to lay a waterproof film on the top of the photovoltaic support, the staff first ensures that the film laying roller 9 contains enough waterproof film. Then the staff manually pulls the waterproof film and fixes it to the leftmost side of the photovoltaic support 1. Then the staff starts the first motor 5. The operation of the first motor 5 drives the transmission wheel 6 to rotate. The two groups of transmission wheels 6 drive the moving wheels 7 to rotate through the synchronous belt 8. Further, the two groups of moving sliders 3 start to move to the right. When the moving sliders 3 move, the staff starts the second motor 22. The second motor 22 makes the film laying roller 9 rotate, so that the waterproof film in the film laying roller 9 is pulled out to realize film laying. During the film laying operation, since the first baffle 12 and the second baffle 13 are elastically connected by the arc-shaped spring 14, the first baffle 12 is always subjected to the force provided by the arc-shaped spring 14. Further, the connecting rod 11 rotates counterclockwise. At this time, the pressing roller 15 between the two groups of connecting rods 11 will always abut against the surface of the photovoltaic panel 2 to flatten the laid waterproof film and ensure that the waterproof film is closely attached to the photovoltaic panel 2. After the film laying operation is completed, the staff cuts the waterproof film and presses the edge of the waterproof film against the photovoltaic support 1. Finally, the staff starts the first motor 5 to reverse the output shaft of the first motor 5, so that the housing 4 moves to the standby support 26 to standby without interfering with the photovoltaic power generation operation of the photovoltaic panel 2.

[0031] Through the operation of the first motor 5, two groups of moving sliders 3 are driven to start displacing along the photovoltaic support 1. Through the operation of the second motor 22, the film laying roller 9 rotates to perform the film laying operation. During film laying, the pressing roller 15 will always be in contact with the surface of the photovoltaic panel 2 through the elastic potential energy of the arc spring 14, flattening the waterproof film. Compared with traditional devices, through the operation of the first motor 5, this device enables the film laying roller 9 to automatically displace along the surface of the photovoltaic support 1, while laying the waterproof film on the surfaces of the photovoltaic support 1 and the photovoltaic panel 2. Then, through the pressing roller 15, the film is flattened, making the waterproof film laying operation faster, saving manpower and material resources, and improving work efficiency.

[0032] Both the front and rear sides of the film laying roller 9 are fixedly installed with connecting cylinders 16, and installation grooves 17 are opened at both the upper and lower ends of the connecting cylinders 16;

[0033] On both the front and rear sides inside the housing 4, connecting blocks 18 are rotatably installed. At both the upper and lower ends of the connecting blocks 18, movable grooves 19 are opened. Inside the movable grooves 19, installation blocks 20 are movably installed. The installation blocks 20 and the inside of the connecting blocks 18 are elastically connected through springs 21, and the installation blocks 20 are located inside the installation grooves 17.

[0034] When the waterproof film inside the film laying roller 9 is insufficient, the staff presses the two installation blocks 20 on the front side of the film laying roller 9 inward, so that the installation blocks 20 are received inside the movable grooves 19. Then, the staff rotates the knob 25, and the knob 25 drives the lead screw 24 to rotate. The lead screw 24 drives the connecting block 18 threadedly sleeved thereon to move inside the rotating shaft 23, further separating the connecting cylinder 16 from the connecting block 18. At this time, the front side of the film laying roller 9 is disassembled. Then, the staff presses the two installation blocks 20 on the rear side of the film laying roller 9 inward and simultaneously pulls the film laying roller 9 outwards to remove the film laying roller 9. After adding the waterproof film to the film laying roller 9, the staff aligns the connecting cylinder 16 on the rear side of the film laying roller 9 with the connecting block 18 and simultaneously pushes the connecting cylinder 16 into the connecting block 18. When the connecting cylinder 16 is pushed in, the two installation blocks 20 will be received inside the movable grooves 19. After the connecting cylinder 16 is completely reset, the two installation blocks 20 will enter the installation grooves 17 inside through the elastic potential energy of the springs 21 to complete the fixation. Similarly, at this time, the staff rotates the knob 25 to reset the front connecting block 18, fixing the front side of the film laying roller 9 to the connecting block 18 to complete the installation.

[0035] By pressing two groups of mounting blocks 20, they are received into the interior of the movable groove 19, so that the connecting cylinders 16 on both sides of the front side of the film laying roller 9 are disengaged from the fixation. By rotating the knob 25, the front connecting block 18 is received into the interior of the rotating shaft 23, enabling the film laying roller 9 to be easily disassembled. Compared with traditional devices, this device fixes between the connecting cylinder 16 and the connecting block 18 through two groups of mounting blocks 20, making the disassembly and installation operations of the film laying roller 9 faster, facilitating the replacement and replenishment of the film laying roller 9, and improving the working efficiency of the film laying operation.

[0036] Among them, a first motor 5 is fixedly installed on the outer wall of the moving slider 3. Transmission wheels 6 are rotatably installed on both the left and right sides inside the moving slider 3. The two transmission wheels 6 are connected by a synchronous belt 8. Both transmission wheels 6 are fixedly connected to the moving wheels 7, and the moving wheels 7 are movably installed inside the photovoltaic support 1.

[0037] When the staff starts the first motor 5, the operation of the first motor 5 drives the transmission wheel 6 to rotate. Through the transmission of the synchronous belt 8 by the two transmission wheels 6, the moving wheels 7 rotate, and further the two moving sliders 3 start to displace.

[0038] Among them, a standby support 26 is fixedly installed on the left side of the photovoltaic support 1, and a photovoltaic panel 2 is arranged on the top of the moving slider 3.

[0039] When the staff starts the first motor 5 and reverses the output shaft of the first motor 5, the housing 4 is moved to the standby support 26 for standby without interfering with the photovoltaic power generation operation of the photovoltaic panel 2.

[0040] Among them, a second motor 22 is fixedly installed on the rear side of the housing 4, and the output shaft of the second motor 22 is fixedly connected to the rear connecting block 18.

[0041] When the staff starts the second motor 22, the second motor 22 rotates the film laying roller 9, so that the waterproof film inside the film laying roller 9 is drawn, realizing film laying.

[0042] Among them, a rotating shaft 23 is rotatably installed on the front side of the housing 4, and the front connecting block 18 is movably installed inside the rotating shaft 23.

[0043] Among them, a lead screw 24 is rotatably installed inside the rotating shaft 23. One end of the lead screw 24 is threadedly sleeved with the front connecting block 18, and the other end of the lead screw 24 is fixedly connected to the knob 25.

[0044] When the staff rotates the knob 25, the knob 25 drives the lead screw 24 to rotate. The lead screw 24 drives the connecting block 18 threadedly sleeved with it to move into the interior of the rotating shaft 23, further disengaging the connecting cylinder 16 from the connecting block 18, facilitating the disassembly of the film laying roller 9.

[0045] The working principle and usage process of the present utility model:

[0046] When it is necessary to lay a waterproof film on the top of the photovoltaic support, the staff first ensure that the film laying roller 9 contains enough waterproof film. Then the staff manually pull the waterproof film and fix it to the leftmost side of the photovoltaic support 1. Then the staff start the first motor 5. The operation of the first motor 5 drives the transmission wheel 6 to rotate. Through the transmission of the synchronous belt 8 between the two groups of transmission wheels 6, the moving wheels 7 rotate. Further, the two groups of moving sliders 3 start to move to the right. When the moving sliders 3 are moving, the staff start the second motor 22. The second motor 22 makes the film laying roller 9 rotate, so that the waterproof film in the film laying roller 9 is pulled, realizing film laying. During the film laying operation, since the first baffle 12 and the second baffle 13 are elastically connected by the arc spring 14, the first baffle 12 is always subjected to the force provided by the arc spring 14. Further, the connecting rod 11 rotates counterclockwise. At this time, the pressing roller 15 between the two groups of connecting rods 11 will always be in contact with the surface of the photovoltaic panel 2, flattening the laid waterproof film and ensuring that the waterproof film is closely attached to the photovoltaic panel 2. After the film laying operation is completed, the staff cut the waterproof film and press the edge of the waterproof film against the photovoltaic support 1. Finally, the staff start the first motor 5 to reverse the output shaft of the first motor 5, so that the housing 4 moves to the standby support 26 to standby without interfering with the power generation operation of the photovoltaic panel 2.

[0047] When the waterproof film in the film laying roller 9 is insufficient, the staff press the two groups of mounting blocks 20 on the front side of the film laying roller 9 inward, so that the mounting blocks 20 are received into the inside of the movable groove 19. Then the staff rotate the knob 25. The knob 25 drives the screw rod 24 to rotate. The screw rod 24 drives the connecting block 18 sleeved with its thread to move into the inside of the rotating shaft 23. Further, the connecting cylinder 16 is disengaged from the connecting block 18. At this time, the front side of the film laying roller 9 is disassembled. Then the staff press the two groups of mounting blocks 20 on the rear side of the film laying roller 9 inward and pull the film laying roller 9 outwards at the same time, so that the film laying roller 9 is removed. After adding the waterproof film to the film laying roller 9, the staff align the connecting cylinder 16 on the rear side of the film laying roller 9 with the connecting block 18 and push the connecting cylinder 16 into the connecting block 18 at the same time. When the connecting cylinder 16 is pushed in, the two groups of mounting blocks 20 will be received into the inside of the movable groove 19. After the connecting cylinder 16 is completely reset, the two groups of mounting blocks 20 will enter the inside of the mounting groove 17 through the elastic potential energy of the spring 21 to complete the fixation. Similarly, at this time, the staff rotate the knob 25 to reset the front connecting block 18, so that the front side of the film laying roller 9 is fixed to the connecting block 18 to complete the installation.
