Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically a self-lifting structure and a photovoltaic support for water areas. Background Technology

[0002] Waterborne photovoltaic (PV) power plants have become an important development direction in the new energy field due to their lack of land occupation and high power generation efficiency. Currently, most waterborne PV systems employ fixed pile foundations or floating pontoon structures. Fixed pile foundation waterborne PV systems, as the name suggests, refer to a support system that uses pile foundations to fix PV modules at a fixed angle and position on the water surface. It mainly consists of columns (piles), main beams, purlins, and welded components. These components together form a stable support structure to support the PV modules and maintain them at the optimal angle for receiving sunlight.

[0003] Water levels in water bodies fluctuate frequently seasonally, causing photovoltaic panels to operate in suboptimal conditions for extended periods. To prevent excessively high water levels, the mounting piles are often installed at higher elevations. This increases the difficulty of inspecting and replacing the brackets and photovoltaic modules, requiring specialized equipment (such as ships and cranes), which in turn raises maintenance costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a self-lifting structure and a photovoltaic support for water areas. The lifting structure facilitates maintenance personnel to ascend to the area below photovoltaic panels and other components for maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-lifting structure, including a base plate installed on a photovoltaic bracket, a drive mechanism fixedly connected to the base plate, two steel wire ropes fixedly connected to the drive mechanism, hooks fixedly connected to the front ends of the two steel wire ropes, adjustment mechanisms fixedly connected to both sides of the base plate, the steel wire ropes pressing on the adjustment mechanisms, a moving component slidably connected to the photovoltaic bracket, and an annular plate fixedly connected to the moving component.

[0006] Furthermore, the driving mechanism includes two support plates fixedly connected to the base plate, a rotating shaft rotatably connected between the two support plates, three limiting plates fixedly connected to the rotating shaft, a driver fixedly connected to the base plate, and the output end of the driver fixedly connected to the rotating shaft.

[0007] Furthermore, the driver is a reversible motor, and the power generated by the photovoltaic panel supplies power to the driver.

[0008] Furthermore, the adjustment mechanism includes two L-shaped rods fixedly connected to the base plate, a round rod fixedly connected between the two L-shaped rods, and a guide wheel sleeved on the round rod.

[0009] Furthermore, the movable component includes a circular tube sleeved on a photovoltaic bracket, a rotating block fixedly connected to the inner wall of the circular tube, a rotating shaft two rotatably connected to the rotating block, a roller fixedly connected to the rotating shaft two, and a hanging lug fixedly connected to the upper end of the circular tube.

[0010] Furthermore, several rubber anti-slip blocks are fixedly connected to the annular plate.

[0011] A photovoltaic support structure for water areas includes a column with a support frame detachably connected to it. The photovoltaic support structure also includes the aforementioned self-lifting structure, with a base plate fixedly connected to the support frame and a round tube sleeved on the column.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This self-lifting structure and water-based photovoltaic support system, through the cooperation of the drive mechanism, adjustment mechanism and moving component, can move the ring plate up and down along the surface of the column. Thus, when maintenance personnel stand on the ring plate, they can move it directly under the photovoltaic panel to inspect and repair the support system and photovoltaic modules.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1 to 3A self-lifting structure includes a base plate 3 installed on a photovoltaic bracket. A drive mechanism is fixedly connected to the base plate 3. Two steel wire ropes 4 are fixedly connected to the drive mechanism. A hook 5 is fixedly connected to the front end of each of the two steel wire ropes 4. An adjustment mechanism is fixedly connected to both sides of the base plate 3. The steel wire ropes 4 are pressed on the adjustment mechanism. A moving component is slidably connected to the photovoltaic bracket. An annular plate 6 is fixedly connected to the moving component.

[0020] like Figures 1 to 3 As shown, in use, the self-lifting structure of this utility model uses a drive mechanism to release and rewind the wire rope 4. When it is necessary to inspect and repair the bracket and photovoltaic modules, the drive mechanism controls the release of the wire rope 4, causing the wire rope 4 to slide along the adjusting component. The moving component at the lower end of the wire rope 4 moves downward along the photovoltaic bracket, thereby lowering the ring plate 6 to a lower position so that the staff can stand on the ring plate 6. Conversely, the drive mechanism is activated to rewind the wire rope 4, thereby moving the ring plate 6 upward to move the staff below the photovoltaic panel for inspection and repair of the bracket and photovoltaic modules. During this movement, the staff needs to hold onto the photovoltaic bracket to avoid falling.

[0021] like Figure 3 As shown, the driving mechanism includes two support plates 7 fixedly connected to the base plate 3, a rotating shaft 8 rotatably connected between the two support plates 7, three limiting plates 9 fixedly connected to the rotating shaft 8, a driver 10 fixedly connected to the base plate 3, and the output end of the driver 10 fixedly connected to the rotating shaft 8.

[0022] Specifically, the driver 10 is activated, which drives the rotating shaft 8 to rotate, thereby winding or releasing the steel wire rope 4 fixedly connected to the limit plate 9. It should be noted that each driver 10 on the photovoltaic bracket is numbered and can be turned on and off using existing remote control technology.

[0023] like Figure 3 As shown, the driver 10 is a forward and reverse rotating motor, and the power generated by the photovoltaic panel supplies power to the driver 10.

[0024] Specifically, the forward and reverse motor can control the forward and reverse rotation of the shaft 8, thereby controlling the winding and unwinding of the wire rope 4.

[0025] like Figure 3 As shown, the adjustment mechanism includes two L-shaped rods 11 fixedly connected to the base plate 3, and a round rod 12 fixedly connected between the two L-shaped rods 11. A guide wheel 13 is sleeved on the round rod 12.

[0026] Specifically, during the winding or unwinding process, the wire rope 4 is pressed against the guide wheel 13. The rotation of the guide wheel 13 can prevent the wire rope 4 from being worn.

[0027] like Figure 2 As shown, the movable component includes a circular tube 14 sleeved on a photovoltaic bracket, a rotating block 15 fixedly connected to the inner wall of the circular tube 14, a rotating shaft 16 rotatably connected to the rotating block 15, a roller 17 fixedly connected to the rotating shaft 16, and a hanging ear 18 fixedly connected to the upper end of the circular tube 14.

[0028] Specifically, the wire rope 4 is detachably connected to the hanging ear 18 via the hook 5. During the winding process, the wire rope 4 applies an upward pulling force to the hanging ear 18. Through the roller 17 set inside the round tube 14, it can move upward along the surface of the photovoltaic bracket. Before the maintenance personnel stand on the ring plate 6, they can move downward using their own weight.

[0029] like Figure 2 As shown, several rubber anti-slip blocks 19 are fixedly connected to the annular plate 6.

[0030] Specifically, the rubber anti-slip block 19 can provide an anti-slip effect, thereby reducing the possibility of maintenance personnel falling.

[0031] A photovoltaic support structure for water areas includes a column 1, a support frame 2 detachably connected to the column 1, the photovoltaic support structure also includes the aforementioned self-lifting structure, a base plate 3 fixedly connected to the support frame 2, and a round tube 14 sleeved on the column 1.

[0032] Specifically, the column 1 is first installed on the water surface. When installing the support frame 2, the round tube 14 on the moving component needs to be put on the column 1 first during the transportation process of the support frame 2, and then the installation between the support frame 2 and the column 1 is completed.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
