Description

Technical Field

[0001] This utility model belongs to the field of maintenance floating platform technology, specifically, it relates to a floating platform for operation and maintenance of a floating photovoltaic power station. Background Technology

[0002] A photovoltaic (PV) power station is a facility that generates electricity using solar energy. Its core principle is based on the photovoltaic effect, directly converting solar energy into electrical energy. A PV power station mainly consists of solar panels, inverters, energy storage batteries, as well as supporting structures and cables. It is widely used in areas without electricity, for solar-powered consumer electronics, and for grid-connected power generation. With technological advancements, the construction of PV power stations is no longer limited to land; numerous PV power stations have also been built in reservoirs, ponds, and tidal flats.

[0003] Due to the unique climatic conditions of reservoirs and ponds, floating solar power stations are more susceptible to the effects of humidity and waterbirds. Therefore, the operation and maintenance of floating solar power stations is more frequent than that of ground-mounted solar power stations, requiring regular cleaning of bird droppings and feathers from the solar panels, as well as the removal of rusted components. Typically, maintenance and repairs of floating solar power stations require traveling by boat to the station, then using ladders erected on the boat to access and inspect the facilities.

[0004] However, in actual operation, since the hull and ladder are not professional maintenance tools, the hull usually needs to be designed to be wide in order to ensure the stability of the hull. This makes it difficult for the hull to enter the photovoltaic panel area, and there are a series of problems such as inconvenience in operation, which has certain limitations. Utility Model Content

[0005] To address the technical problem in existing technologies where the hull cannot operate in different construction environments, leading to difficulties in operation and maintenance for personnel, this utility model provides a floating platform for the operation and maintenance of a floating photovoltaic power station.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A floating platform for the operation and maintenance of a floating photovoltaic power station includes floats arranged parallel to each other on the water surface; multiple second fixed square tubes are fixedly connected to each other on one side of the floats; a bidirectional screw rod is arranged between the second fixed square tubes located in the middle, and the two ends of the bidirectional screw rod are respectively threaded to the corresponding second fixed square tubes; a motor is fixedly installed inside one of the second fixed square tubes located in the middle, and the output end of the motor is connected to the bidirectional screw rod; telescopic square tubes are arranged between the remaining second fixed square tubes located on both sides of the bidirectional screw rod; a support plate is connected to the upper surface of the telescopic square tubes by screws; a horizontally arranged working platform is fixedly connected to the upper part of the support plate; a scissor lift platform is fixedly installed above the working platform.

[0008] Furthermore, the float is provided with a plurality of evenly distributed through grooves; a first fixed square tube is inserted into the through grooves; a first fixed plate and a second fixed plate are respectively fixed to both ends of the first fixed square tube; the second fixed square tube is connected to the second fixed plate at the position corresponding to the first fixed square tube via a square flange.

[0009] Furthermore, the first fixing plate and the second fixing plate are located on both sides of the float, with the first fixing plate located on the outer side.

[0010] Furthermore, each end of the telescopic square tube away from the support plate is fixed with a first anti-detachment block, which has a square structure and fits into the internal space of the second fixed square tube.

[0011] Furthermore, a second anti-detachment block is fixed to both ends of the bidirectional lead screw. The second anti-detachment block has a circular structure and is rotatably disposed inside the corresponding second fixed square tube.

[0012] Furthermore, a support rod is fixedly connected to the lower surface of the work platform at the position corresponding to each of the second fixed square tubes; a roller is rotatably connected to the lower end of each support rod, and the roller abuts against the upper surface of the second fixed square tube.

[0013] Furthermore, the support plate is fixedly connected to two fixing blocks at the positions corresponding to the bidirectional lead screw; accordion covers are fitted onto the bidirectional lead screw at the positions corresponding to both sides of the support plate.

[0014] Furthermore, the fixing block consists of two parts: a rectangular block and a circular block. The circular block is rotatably connected to a bidirectional lead screw, and the rectangular block is fixed to a support plate. The two ends of the bellows cover are respectively connected to the second fixed square tube and the circular block on the fixing block.

[0015] The beneficial effects of this utility model are:

[0016] 1) This utility model utilizes a motor-driven bidirectional lead screw to rotate and move the two second fixed square tubes located in the middle away from each other, thereby increasing the distance between the floats. At this time, the floating platform structure is relatively stable, ensuring that the floating platform can travel normally to the side of the photovoltaic power station. When it is necessary to enter a narrow and difficult-to-access maintenance area, the bidirectional lead screw can rotate in the opposite direction to bring the distance between the two floats closer, thereby narrowing the floating platform and facilitating access to narrow areas. Afterwards, the motor can be used again to increase the distance between the floats, so that the floating platform maintains optimal stability. Then, the operators first board the work platform and then board the scissor lift platform to carry out operation and maintenance of the photovoltaic power station facilities. It can adapt to different construction conditions and improve practicality.

[0017] 2) Because the rollers of this utility model can rotate, when the telescopic square tubes are close to each other, the rollers can still maintain contact with the upper surface of the telescopic square tubes. This can support various local positions on both sides of the work platform, and the work platform will not lose its support function due to the change of the float position. This can ensure the stability of the floating platform and facilitate the operation and maintenance work of the operators. Attached Figure Description

[0031] Please refer to it again. Figure 5 and Figure 6 As shown, a first anti-detachment block 17 is fixedly connected to one end of the telescopic square tube 8 away from the support plate 12. The first anti-detachment block 17 has a square structure and fits into the internal space of the second fixed square tube 6. A second anti-detachment block 18 is fixedly connected to both ends of the bidirectional screw 7. The second anti-detachment block 18 has a circular structure and is rotatably disposed inside the corresponding second fixed square tube 6. The first anti-detachment block 17 and the second anti-detachment block 18 are used to prevent the bidirectional screw 7 and the telescopic square tube 8 from falling out of the corresponding second fixed square tube 6.

[0032] Please refer to it again. Figure 5As shown, a support plate 12 is connected to the upper surface of the telescopic square tube 8 by screws; a horizontally arranged working platform 13 is fixedly connected to the upper part of the support plate 12; a scissor lift platform 14 is fixedly installed above the working platform 13, which is used to lift the workers and facilitate the workers to maintain and repair the photovoltaic facilities; a support rod 15 is fixedly connected to the lower surface of the working platform 13 corresponding to the position of each second fixed square tube 6; a roller 16 is rotatably connected to the lower end of each support rod 15, and the roller 16 abuts against the upper surface of the second fixed square tube 6.

[0033] Please refer to it again. Figure 4 As shown, the support plate 12 is fixed with two fixing blocks 11 at the position corresponding to the bidirectional lead screw 7. Each fixing block 11 consists of a rectangular block and a circular block. The circular block is rotatably connected to the bidirectional lead screw 7, and the rectangular block is fixed to the support plate 12. Bellows protective covers 10 are fitted on both sides of the bidirectional lead screw 7 at the positions corresponding to the two sides of the support plate 12. The two ends of the bellows protective covers 10 are respectively connected to the second fixed square tube 6 and the circular block on the fixing block 11 to prevent the bidirectional lead screw 7 from being corroded and damaged.

[0034] To facilitate understanding of the above-mentioned technical solution of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below:

[0035] When operators need to perform operation and maintenance on the floating photovoltaic power station, they can use motor 9 to drive the bidirectional lead screw 7 to rotate. When the bidirectional lead screw 7 rotates, it is connected to the second fixed square tube 6 in the middle by threads, so it can drive the two second fixed square tubes 6 in the middle to move away from each other, thereby increasing the distance between the floats 1. At this time, the floating platform structure is relatively stable, which can ensure that the floating platform can travel normally to the side of the photovoltaic power station.

[0036] Subsequently, when it is necessary to enter a narrow and difficult-to-access maintenance area, the distance between the two floats 1 can be shortened by driving the motor 9 again to make the bidirectional lead screw 7 rotate in the opposite direction, thereby narrowing the platform and facilitating access to narrow areas.

[0037] Finally, the distance between the floats 1 can be widened again by the motor 9 to maintain the best stability of the floating platform. Then, the operators can first climb onto the work platform 13 and then onto the scissor lift platform 14 to carry out operation and maintenance of the photovoltaic power station facilities. This can adapt to different construction conditions and improve practicality.

[0038] Since all the second fixed square tubes 6 extend and retract synchronously under the action of the bidirectional screw 7, the working platform 13 can always be in the middle position between the two floats 1, ensuring the stability of the working platform 13 and facilitating the operation and maintenance work of the operators.

[0039] Since the roller 16 can rotate, when the telescopic square tubes 8 approach each other, the roller 16 and the upper surface of the telescopic square tubes 8 can still be in contact with each other, so that the various local positions on both sides of the work platform 13 can also be supported. The work platform 13 will not lose its support function due to the change of the position of the float 1, thus ensuring the stability of the floating platform and facilitating the operation and maintenance work of the operators.
