Description

Technical Field

[0001] The utility model relates to a structure for maintaining a photovoltaic panel. Background Art

[0002] Photovoltaic panels are installed on photovoltaic support frames for use. After a certain period of use, when they need maintenance or technical upgrades, they need to be removed from the support frames. Usually, when removing photovoltaic panels from photovoltaic supports, a cart needs to be placed next to the photovoltaic supports, and then the removed photovoltaic panels are placed on the cart and transported away. However, due to different laying scenarios, the cart cannot be moved to the side of the photovoltaic support when removing photovoltaic panels, such as installation areas such as roofs and slopes. This results in each removed photovoltaic panel requiring manual transfer by operators, and the workload of disassembly is usually large. Even if multiple operators work at the same time, the disassembly efficiency cannot be effectively improved in this way, and the labor intensity of the operators is relatively high. In addition, there are certain safety hazards when more operators operate on the roof or slope at the same time. At the same time, when the support frame is laid for a long distance, as the disassembly distance increases, the round-trip distance of the operator will also increase, further increasing the labor intensity.

[0039] The optimal working principle of the utility model is as follows:

[0040] When in use, after the first photovoltaic panel is removed from the photovoltaic support frame 100, the utility model can be placed on the photovoltaic support frame 100 for use. The specific placement method is to place the second rotating column 5 on the upper end of the fourth fixing rod 105 and support it through the fourth fixing rod 105. At this time, the supporting roller 9 is in contact with the outer end of the fourth fixing rod 105, and the limiting cylinder 11 is in contact with the lower end of the fourth fixing rod 105. The two first rotating columns 3 are placed on the fifth fixing rod 106, and the removed photovoltaic panel is placed on the photovoltaic support frame 100, supported by each connecting rod 15 and the supporting column 12, and limited by each supporting rod 2. As more photovoltaic panels are placed, by pushing this structure, it can be returned along the length direction of the photovoltaic support frame 100. After the disassembled photovoltaic panel is removed, the device is pushed forward to continue to disassemble the photovoltaic panel for shipment through this device. In addition, as a preferred embodiment, the utility model also adds The spring 28 and other structures can not only be used with the fourth fixing rod 105 of different sizes, but also have stronger stability during use, and avoid the support roller 9 from falling off the fourth fixing rod 105 when pushing the utility model, causing the entire structure to fall off the photovoltaic support frame 100. The specific method is that when the utility model is placed on the photovoltaic support frame 100, the limiting cylinder 11 is pulled downward, thereby expanding the distance between the limiting cylinder 11 and the second rotating column 5, so that the fourth fixing rod 105 is located between the second rotating column 5 and the limiting cylinder 11. At the same time, it can be suitable for fourth fixing rods 105 of different sizes, and then the limiting cylinder 11 is released. The rebound force of the spring 28 makes the limiting cylinder 11 move upward until the limiting cylinder 11 is in contact with the fourth fixing rod 105. Through the above arrangement, the stability of the entire structure during movement is higher, and it is also effectively prevented from falling during use, which greatly improves safety.

[0041] In addition, by setting the cross bar 10, it is more convenient to pull the two limit cylinders 11 downward at the same time, and the operator can also move the device conveniently through the cross bar 10. In addition, when changing the support column 12 and the installation rod 16 of different lengths, the cross bar 10 will shrink and expand according to the lengths of the different support columns 12 and the installation rod 16. In addition, the utility model is not limited to the use when disassembling the photovoltaic panel. When the maintenance is completed or a new photovoltaic panel is installed, the utility model can also be used for transportation, avoiding the operator from carrying the photovoltaic panel on the slope or roof. When moving the utility model, there is no need to build a track for the utility model. It can be done by installing the bracket of the photovoltaic panel, which is simple and practical.

[0042] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
