Description

Technical Field

[0001] The present invention relates to a leg platform for defect elimination and operation and maintenance of offshore photovoltaic power generation. Background Art

[0002] Solar energy is a renewable and infinite energy source. Therefore, the energy source for offshore photovoltaic power generation is very rich and can meet a large amount of energy demand. The ocean covers most of the earth's area. By building offshore photovoltaic power stations, the dependence on traditional energy sources can be reduced. An offshore photovoltaic power generation system usually consists of photovoltaic panels, brackets, cables, power electronic devices, etc. Among them, the photovoltaic panel is the core component for converting solar energy into electrical energy. When the sun shines on the photovoltaic panel, the light energy is converted into electrical energy and transmitted to the power electronic device through the cable, and finally converted into usable electricity.

[0003] Currently, the platforms in offshore photovoltaic fields are distributed relatively densely. The spacing between rows of platforms is about 26m, and the height of the platforms from the sea surface is 7 - 11m. There are the following problems when traditional traffic boats navigate in offshore photovoltaic fields: 1. The height of the traffic boat cab is too high, and it is very easy to collide with the platforms when entering and leaving between the platforms; 2. The platform spacing is less than the turning radius of the traffic boat, and the traffic boat cannot turn around; 3. The structural strength of the platform is relatively low and cannot withstand the impact force brought by the berthing of the traffic boat. Therefore, a leg platform for defect elimination and operation and maintenance of offshore photovoltaic power generation is proposed to solve the above problems. Summary of the Invention

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] As shown in Figures 1-6, a maintenance and defect elimination leg platform for offshore photovoltaic power generation includes a support main body 1, a platform lifting mechanism 2, a power generation device 3, and a paddle hanging machine 4; the platform lifting mechanism 2 is arranged at the four corners of the support main body 1; the power generation device 3 is arranged on the upper end surface of the support main body 1; the paddle hanging machine 4 is arranged on the side wall of the support main body 1; the support main body 1 includes a steel truss 101, a filler, and two steel plates 103. The filler is arranged inside the steel truss 101, and the upper and lower end surfaces of the steel truss 101 are respectively connected to the steel plates 103; pile insertion holes 111 are arranged at the four corners of the support main body 1.

[0029] As shown in Figure 2, the platform lifting mechanism 2 includes four leg piles 201, four winches 202, four lifting steel wires 203, four pile pulling steel wires 204, and four groups of guiding supports 205; the four leg piles 201 are respectively inserted into the four pile insertion holes 111; an upper roller 207 is arranged at the upper end of each leg pile 201, two lower rollers 208 are arranged in the middle of each leg pile 201, and a group of guiding supports 205 is arranged inside each leg pile 201. The guiding supports 205 are connected to the steel plates 103; a lifting lug 209 is arranged on the outer side of each leg pile 201, and the lifting lug 209 is connected to the steel plates 103; a winch 202 is arranged inside each leg pile 201, and the winch 202 is connected to the steel plates 103; one end of the lifting steel wire 203 is connected to the winch 202, and the other end passes through the guiding roller 206 on the guiding support 205, then passes through the upper roller 207 and is connected to the lifting lug 209; one end of the pile pulling steel wire 204 is connected to the winch 202, and the other end passes through the guiding roller 206 on the guiding support 205, then passes through the two lower rollers 208 and is connected to the lifting lug 209.

[0030] Specifically, when the platform is lifted, the pile-pulling steel wire rope 204 is untied. The leg pile 201 moves downward under gravity until the pile bottom is inserted into the seabed firmly. Then, the lifting steel wire rope 203 is connected. At the same time, 4 winches 202 are started, and the lifting steel wire rope 203 is tightened. The lifting steel wire rope 203 applies an upward pulling force to the support main body 1 through the lifting lug 209 to lift the support main body 1. Observe the levelness of the support main body 1 during the lifting process. The winches 202 can be started and stopped and the speed can be adjusted until the support main body 1 is lifted out of the sea level. When the platform descends, the winches 202 are controlled to release the lifting steel wire rope 203. The upward pulling force on the support main body 1 decreases, and under the influence of gravity, it slowly descends until the support main body 1 falls into the sea water and floats on the sea surface by its own buoyancy. When pulling out the pile and shifting the position, the lifting steel wire rope 203 is untied, the pile-pulling steel wire rope 204 is connected to the winch 202, and the winch 202 is controlled to tighten the pile-pulling steel wire rope 204. The pile-pulling steel wire rope 204 applies an upward pushing force to the leg pile 201 through the roller 208 to lift the leg pile 201 inserted into the seabed to its initial state.

[0031] As shown in Figure 3, the steel truss 101 includes seven first truss pieces 104, five second truss pieces 105, and two third truss pieces 106. The seven first truss pieces 104 are arranged horizontally, the five second truss pieces 105 are arranged vertically, the seven first truss pieces 104 and the five second truss pieces 105 are cross-connected, and the two third truss pieces 106 are respectively connected to both ends of the five second truss pieces 105. The first truss piece 104 includes two first main steel pipes 107 and seven first connecting steel pipes 108. The two first main steel pipes 107 are arranged in parallel, and the seven first connecting steel pipes 108 are arranged between the two first main steel pipes 107. The second truss piece 105 includes two second main steel pipes 109, seven second connecting steel pipes 110, and six first web members 111. The two second main steel pipes 109 are arranged in parallel, the seven second connecting steel pipes 110 are arranged between the two second main steel pipes 109, and the six first web members 111 are arranged between the seven second connecting steel pipes 110.

The two third main steel pipes 112 are arranged in parallel, seven third connecting steel pipes 113 are arranged between the two third main steel pipes 112, the six second web members 114 are arranged between the seven third connecting steel pipes 113, and two third connecting steel pipes 113 are respectively added to both ends of the two third main steel pipes 112.

[0032] Specifically, the power generation device 3 is a diesel generator, which provides power for the winches 202 and the paddle wheel machine 4 respectively. The paddle wheel machine 4 is installed on the side edge of the steel plate 103. It is powered by the power generation device 3. Through the high-speed rotation of the propeller 401, it pushes the sea water to move forward. The operator controls the control lever 402 to adjust the forward direction of the platform.

[0033] Specifically, the filler can be one of foam, airbag or wood. All are low-density materials and fill the inside of the steel truss 101. Steel plates 103 are fully laid on the top and bottom of the steel truss 101. The steel truss 101 and the steel plates 103 serve as the outer protection of the filler to prevent damage from external forces.

[0034] Specifically, in the lifting condition, a lift 5 (only schematically shown in the figure) is configured on the platform, which can provide a stable working platform for defect elimination and operation and maintenance personnel, or a safe way to go up and down the photovoltaic platform (not shown in the figure). With a boom lift (not shown in the figure), a stable and movable working platform can be provided.

[0035] This offshore photovoltaic defect elimination and operation and maintenance leg platform can not only provide an economical and safe marine vehicle and carrier between photovoltaic platforms, but also independently realize support and positioning, providing a stable and reliable working platform. With the use of equipment such as elevators and boom lifts, it can deliver operators to the platform passage or directly to the damaged photovoltaic panels and lines to carry out defect elimination and operation and maintenance operations.

[0036] This offshore photovoltaic defect elimination and operation and maintenance leg platform can realize free passage within the photovoltaic plant area and can be used as a tool for defect elimination and operation and maintenance personnel and material transportation; the platform is small in volume and low in height, without the risk of colliding with the platform, and can effectively protect the finished products. With elevators and boom lifts, a controllable working platform can be provided, reducing the safety risk of operators climbing the photovoltaic platform and increasing the efficiency of defect elimination and operation and maintenance. Subsequently, corresponding mechanical equipment can be carried according to needs to meet more operation requirements for offshore photovoltaic construction.
