Description

Technical Field

[0001] This invention relates to the field of photovoltaic technology, specifically to a photovoltaic panel transfer device and method for photovoltaic power plant construction. Background Technology

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect at the semiconductor interface to directly convert light energy into electrical energy. It mainly consists of three parts: solar panels, controllers, and inverters, with the main components being electronic devices.

[0003] After production, photovoltaic panels need to be transported to their placement location. Most existing photovoltaic panel transport devices use clamps to hold the panels, which cannot hold them firmly during use. This makes the panels prone to falling off during transport. Furthermore, due to their simple structure, they lack shock absorption capabilities, reducing the applicability of the transport devices. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a device for transporting photovoltaic panels, thereby achieving good stability.

[0005] The objective of this invention can be achieved through the following technical solutions: A photovoltaic panel transfer device for photovoltaic power station construction includes a base, on which a housing is fixedly installed. Multiple placement boxes are arranged inside the housing. A cover plate is fixedly installed on one side of each placement box. An airbag is fixedly installed on the bottom surface of each placement box. The four sides of the airbag are spaced apart from the side walls of the placement box. Water bags are fixedly installed on each of the four side walls of the placement box. An air cylinder is fixedly installed inside the placement box, located within the gap between the airbag and the side walls of the placement box. A piston plate is slidably installed inside the air cylinder, and a piston rod is fixedly installed on the piston plate. The air cylinder is connected to a first air pipe and a second air pipe. The first air pipe is connected to the airbag. One-way valves are installed on both the first and second air pipes.

[0006] As a further aspect of the present invention: multiple sets of movable rails are rotatably installed on both sides of the placement box, and the movable rails are used in conjunction with the fixed rails fixedly installed on the inner side of the housing.

[0007] As a further embodiment of the present invention: a support plate and a top plate for use with the water bladder are rotatably mounted on the side wall of the placement box. The support plate and the top plate are located on both sides of the water bladder, and the top plate is located on the side away from the bottom surface of the placement box. A magnet for adsorbing the top plate is fixedly mounted on the support plate.

[0008] As a further aspect of the present invention: a top block is fixedly installed on the side wall of the placement box, and the support plate contacts the top block when it falls naturally.

[0009] As a further aspect of the present invention, multiple sets of limiting frames for supporting the top plate are fixedly installed on the side wall of the placement box.

[0010] As a further embodiment of the present invention: a glass tube is fixedly installed on one side wall of the placement box, the glass tube is connected to the airbag, a marker block is slidably installed inside the glass tube, and an elastic wire and a pull wire are fixedly connected to both sides of the marker block respectively. The end of the elastic wire away from the marker block is fixedly connected to the side wall of the placement box, and the end of the pull wire away from the marker block is fixedly connected to the middle of the airbag.

[0011] As a further aspect of the present invention: the bottom surface of the placement box is rotatably mounted with a guide wheel located inside the airbag for changing the direction of the pull line, and the section of the pull line away from the marker block is a vertical section.

[0012] The present invention also provides a method for applying to the photovoltaic panel transfer device for photovoltaic power plant construction described above, comprising the following steps: Step S1: Move the piston plate by the piston rod to inflate the airbag with gas; Step S2: Pull out one of the placement boxes. In the initial state, the water bladder is located in the gap between the air bladder and the side wall of the placement box. Place the photovoltaic panel in the middle of the air bladder for support. Step S3: The staff holds the end of the water bag and places it on top of the photovoltaic panel. All four water bags are adjusted, and the photovoltaic panel is pressed onto the water bag by the gravity of the water inside. After placement, the placement box is pushed back into the shell. Step S4: After placing all the photovoltaic panels in the placement boxes, push the base to move and transfer the photovoltaic panels. Then, pull out the placement boxes to release the pressure of the water bag on the photovoltaic panels and take them out.

[0013] The beneficial effects of this invention are: (1) In this invention, the photovoltaic panel is supported by an airbag and pressed onto the airbag by the gravity of the water in the waterbag, thus achieving flexible support and flexible compression of the photovoltaic panel, providing adaptive buffering to prevent damage to the photovoltaic panel during transportation. At the same time, after the waterbag is placed on the photovoltaic panel, the water inside can automatically and evenly distribute the pressure to avoid damage to the photovoltaic panel due to pressure. The airbag is depressed downward under pressure, and the waterbag hangs down along the side of the photovoltaic panel, thus achieving flexible restriction of the four sides of the photovoltaic panel, ensuring that the photovoltaic panel will not be displaced in the horizontal plane during transportation, and further improving the stability of the photovoltaic panel transportation.

[0014] (2) In this invention, the support plate and the top plate ensure that when the base is tilted or even bumped, the water in the water bag can only flow towards the top plate and cannot cross it, thereby preventing the water flow from causing the water bag to detach from the photovoltaic panel. Furthermore, the water bag cannot enter the gap between the air bag and the side wall of the placement box under the support of the support plate. After the base is stabilized, the water will flow back to the top of the photovoltaic panel under the action of gravity to reset, thus ensuring the stability of the water bag in fixing the photovoltaic panel.

[0015] (3) In this invention, the distance from the bottom of the photovoltaic panel to the bottom of the placement box can be obtained by observing the position of the marker block through the glass tube. If the distance from the bottom of the photovoltaic panel to the bottom of the placement box is too small, gas is delivered into the airbag through the piston plate and piston rod. The gas volume in the airbag increases and can lift the photovoltaic panel upward, ensuring that the distance from the bottom of the photovoltaic panel to the bottom of the placement box is sufficient, ensuring that the airbag has sufficient buffer space, avoiding collision between the photovoltaic panel and the bottom of the placement box, and improving the stability of the support.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-9 As shown, the present invention is a photovoltaic panel transfer device for photovoltaic power station construction, including a base 1, a handle 7 fixedly installed on the base 1, multiple sets of universal wheels 8 rotatably installed on the base 1, a housing 2 fixedly installed on the base 1, multiple sets of placement boxes 3 arranged inside the housing 2, a cover plate 4 fixedly installed on one side of the placement box 3, an airbag 9 fixedly installed on the bottom surface inside the placement box 3, the four sides of the airbag 9 are spaced from the side walls of the placement box 3, water bags 10 are fixedly installed on each of the four side walls inside the placement box 3, an air cylinder 21 is fixedly installed inside the placement box 3, the air cylinder 21 is located in the space between the airbag 9 and the side walls of the placement box 3, a piston plate 22 is slidably installed inside the air cylinder 21, a piston rod 23 is fixedly installed on the piston plate 22, the air cylinder 21 is connected to a first air pipe 24 and a second air pipe 25, the first air pipe 24 is connected to the airbag 9, and a one-way valve is provided on both the first air pipe 24 and the second air pipe 25.

[0029] In practical application, the piston rod 23 drives the piston plate 22 to move, and gas is delivered into the air cylinder 21 through the second air pipe 25. Then, the gas enters the airbag 9 through the first air pipe 24 to inflate the airbag 9. When transporting the photovoltaic panel, one set of placement boxes 3 is pulled out. In the initial state, the water bag 10 is folded and placed in the gap between the airbag 9 and the side wall of the placement box 3. One end of the water bag 10 is fixed to the upper part of the side wall of the placement box 3, and the other end is free. The photovoltaic panel is placed in the middle of the airbag 9 for support. Then, the worker pulls the free end to unfold the water bag 10 and cover the photovoltaic panel. Since the water bag 10 is connected to the side wall of the placement box 3 at a high height, the water in the water bag 10 will move to the area above the photovoltaic panel under the action of gravity. Since the water bag 10 passes the side of the photovoltaic panel, part of the water bag 10 will hang down along the side of the photovoltaic panel under the action of gravity. The above steps are repeated to transport all four sets of water bags 10. After adjustment, the photovoltaic panel can be pressed onto the airbag 9 by the gravity of the water in the water bladder 10. After placement, the placement box 3 is pushed back into the housing 2. After placing photovoltaic panels into all the placement boxes 3, the base 1 can be moved to transport the photovoltaic panels. During the transport, the photovoltaic panel is supported by the airbag 9, and the photovoltaic panel is pressed onto the airbag 9 by the gravity of the water in the water bladder 10. This achieves flexible support and flexible compression of the photovoltaic panel, providing adaptive buffering to prevent damage from bumps during transport. At the same time, after the water bladder 10 is placed on the photovoltaic panel, the water inside can automatically and evenly distribute the pressure to avoid damage to the photovoltaic panel due to pressure. The downward indentation of the airbag 9 under pressure, combined with the downward drooping of the water bladder 10 along the side of the photovoltaic panel, achieves flexible restriction on the four sides of the photovoltaic panel, ensuring that the photovoltaic panel will not shift in the horizontal plane during transport, further improving the stability of the photovoltaic panel transport. Afterwards, the placement box 3 is pulled out, the pressure of the water bladder 10 on the photovoltaic panel is released, and the photovoltaic panel can be taken out.

[0030] Please see Figures 2-7 As shown, the present invention is a photovoltaic power station construction photovoltaic panel transfer device. Multiple sets of movable rails 5 are rotatably installed on both sides of the placement box 3. The movable rails 5 are used in conjunction with the fixed rails 6 fixedly installed on the inner side of the housing 2.

[0031] In practical application, the movable rail 5 and the fixed rail 6 are connected to form a side-mounted rail structure. This structure is a three-section rail. The movable rail 5 and the fixed rail 6 work together to realize the pushing and pulling movement of the placement box 3. The three-section rail can completely pull the placement box 3 out of the shell 2, which is convenient for the placement and removal of the photovoltaic panel.

[0032] Please see Figures 1-4As shown, the present invention is a photovoltaic panel transfer device for photovoltaic power station construction. A support plate 11 and a top plate 13 are rotatably installed on the side wall of the placement box 3 to cooperate with the water bag 10. The support plate 11 and the top plate 13 are located on both sides of the water bag 10, and the top plate 13 is located on the side away from the bottom surface of the placement box 3. A magnet 15 for adsorbing the top plate 13 is fixedly installed on the support plate 11.

[0033] Specifically, a top block 12 is fixedly installed on the side wall of the placement box 3, and the support plate 11 contacts the top block 12 when it falls naturally.

[0034] Specifically, multiple sets of limiting brackets 14 for supporting the top plate 13 are fixedly installed on the side wall of the placement box 3.

[0035] In practical application, the top plate 13 is rotatably installed and is normally held horizontally by the limiting frame 14. After the photovoltaic panel is placed and the water bag 10 is adjusted, the support plate 11 is rotated upwards so that the magnet 15 on the support plate 11 contacts and attracts the top plate 13. Due to the action of the limiting frame 14, the top plate 13 cannot move downwards, and the support plate 11 can be kept fixed. The support plate 11 contacts the lower surface of the water bag 10, and the top plate 13 presses the water bag 10 tightly against the support plate 11, thereby preventing the water in the water bag 10 from flowing downwards. The water flows over the top plate 13 and through the support plate 11 and the top plate 13, so that when there are subsequent bumps or even when the base 1 tilts, the water in the water bag 10 can only flow towards the top plate 13 and cannot cross it. This prevents the water flow from causing the water bag 10 to detach from the photovoltaic panel. Moreover, under the support of the support plate 11, the water bag 10 cannot enter the gap between the air bag 9 and the side wall of the placement box 3. After the base 1 is stabilized, the water will flow back to the top of the photovoltaic panel and reset under the action of gravity, ensuring the stability of the water bag 10 in fixing the photovoltaic panel.

[0036] Please see Figure 5 , Figure 8 , Figure 9 As shown, the present invention is a photovoltaic panel transfer device for photovoltaic power station construction. A glass tube 18 is fixedly installed on one side wall of the placement box 3. The glass tube 18 is connected to the airbag 9. A marker block 19 is slidably installed inside the glass tube 18. An elastic line 20 and a pull line 16 are fixedly connected to both sides of the marker block 19, respectively. The end of the elastic line 20 away from the marker block 19 is fixedly connected to the side wall of the placement box 3, and the end of the pull line 16 away from the marker block 19 is fixedly connected to the middle of the airbag 9.

[0037] Specifically, a guide wheel 17 for changing the direction of the pull cable 16 is rotatably installed on the bottom surface of the placement box 3, located inside the airbag 9. The section of the pull cable 16 away from the marker block 19 is a vertical section.

[0038] In practical application, after the photovoltaic panel is placed on the airbag 9 and fixed, the airbag 9 is subjected to pressure, and its top wall moves downward. The top wall of the airbag 9 is compressed and sinks, the pull wire 16 loosens, the elastic wire 20 retracts and pulls the marker block 19 to one side. The position of the marker block 19 is observed through the glass tube 18. The position of the marker block in the glass tube 18 reflects the amount of airbag sinking, thereby indirectly indicating the distance between the bottom of the photovoltaic panel and the bottom surface of the placement box 3. If the distance between the bottom of the photovoltaic panel and the bottom surface of the placement box 3 is too small, gas is supplied into the airbag 9 through the piston plate 22 and the piston rod 23. The gas volume in the airbag 9 increases, which can lift the photovoltaic panel upward, ensuring that the distance between the bottom of the photovoltaic panel and the bottom surface of the placement box 3 is sufficient, ensuring that the airbag 9 has sufficient buffer space, avoiding collision between the photovoltaic panel and the bottom of the placement box 3, and improving the stability of the support.

[0039] Please see Figures 1-4 As shown, the present invention is a method applied to the photovoltaic panel transfer device for photovoltaic power station construction described above, which includes the following steps: Step S1: The piston plate 22 is moved by the piston rod 23 to inflate the airbag 9 with gas; Step S2: Pull out one of the placement boxes 3. In the initial state, the water bag 10 is located in the gap between the air bag 9 and the side wall of the placement box 3. Place the photovoltaic panel in the middle of the air bag 9 for support. Step S3: The staff holds the end of the water bag 10 and places the water bag 10 on top of the photovoltaic panel. All four sets of water bags 10 are adjusted. The photovoltaic panel is pressed onto the air bag 9 by the gravity of the water inside the water bag 10. After placement, the placement box 3 is pushed back into the shell 2. Step S4: After placing all the photovoltaic panels in the placement boxes 3, push the base 1 to move and transfer the photovoltaic panels. Then, pull out the placement boxes 3, release the pressure of the water bag 10 on the photovoltaic panels, and you can take out the photovoltaic panels.
