Description

Technical Field

[0001] This utility model relates to the field of offshore wind power technology, specifically to a concrete floating platform for a floating photovoltaic power station. Background Technology

[0002] Different regions, sectors, and industries are implementing tailored policies based on local conditions to accelerate the green transformation of production and lifestyles. The construction of photovoltaic power stations has shifted from precious land to the vast water areas, where aquaculture can be conducted, achieving a "win-win" situation for both fisheries and power generation. Currently, reservoirs, ponds, and the water surfaces of coal mining subsidence areas are the main areas for constructing floating photovoltaic power stations.

[0003] Traditional floating system layouts use an integrated connection between the support frame and the float. During the manufacturing process of the float, connection holes are pre-embedded or connectors are installed. When manufacturing the support frame, ensure that its size and shape meet the design requirements. Place the support frame on the float and fix it with bolts, flanges or other connectors.

[0004] The shortcomings of the above-mentioned solutions are: large amount of floating material required, low power generation efficiency on the back of the double-glass modules, high water coverage, and insufficient light transmittance on the water surface, which affects aquaculture. Previously, vacuum steel drums were used as the floating platform for the transformer substation foundation, which had problems such as poor corrosion resistance, low stability, and high manufacturing costs. Conventional flat iron grounding has technical problems such as poor corrosion resistance, low conductivity, and a large amount of welding work. Utility Model Content

[0005] The purpose of this invention is to provide a concrete floating platform for floating photovoltaic power stations, addressing the problems of excessive floating material usage, low back-side power generation efficiency of double-glass modules, high water coverage, insufficient light transmittance, and negative impacts on aquaculture in existing technologies. Previously, vacuum-type steel drums were used as the foundation floating platform for transformer substations, which suffered from poor corrosion resistance, low stability, and high manufacturing costs. Conventional flat iron grounding methods also presented challenges such as poor corrosion resistance, low conductivity, and extensive welding work.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] A concrete floating platform for a floating photovoltaic power station, including a construction platform;

[0008] The construction platform is assembled from multiple panels and can float on the water surface. The platform has two floats, a first float and a second float. Each float has a rod connected to it, and multiple anchor blocks are connected to each float. These anchor blocks are assembled together, and each anchor block is connected to an anchor rope. A connecting rod is connected to the side of each anchor block, and a pusher is connected to the connecting rod. A base is connected to the end of each anchor block away from the pusher, and a connecting beam is connected to the base. A connecting frame is connected to the end of the connecting beam away from the base.

[0009] As a further embodiment of this utility model: a main grounding grid is connected between the first float and the second float.

[0010] As a further embodiment of this utility model: an indirect grounding net is connected between the first float and the second float.

[0011] As a further embodiment of this utility model, the anchor blocks are nested together by means of a concave-convex design.

[0012] As a further embodiment of this invention, the anchor rope is made of nylon.

[0013] As a further embodiment of this invention, the actuator is hydraulically driven.

[0014] As a further embodiment of this utility model, the base is a gravity-type base.

[0015] As a further embodiment of this utility model: the connecting frame and the connecting beam form a V-shaped structure.

[0016] As a further embodiment of this utility model: the end of the connecting frame away from the connecting beam is connected to a bracket, and the end of the bracket away from the connecting frame is connected to a floating platform for anchoring.

[0017] As a further embodiment of this utility model, the bracket is made of stainless steel.

[0018] The beneficial effects of this utility model are:

[0019] 1. When a photovoltaic power station needs to be installed or maintained, the construction platform can float to a designated location. Through the anchoring effect of anchor blocks and anchor ropes, the floating platform can be stably fixed on the water surface, preventing it from moving due to wind or water flow. Through the adsorption and friction between the anchor blocks and the bottom silt, as well as the weight of the anchor blocks, the floating platform can effectively resist wind and waves in both horizontal and vertical directions. The design of the floating platform makes the installation and maintenance of photovoltaic panels relatively easy, and workers can operate directly on the floating platform.

[0020] 2. This utility model analyzes the stress on the photovoltaic power generation unit and throws concrete blocks around the array so that the array as a whole relies on the adsorption and friction between the bottom of the anchor block and the bottom silt to restrain wind and waves in the horizontal direction. In the vertical direction, the buoyancy of the array is restrained by the self-weight of the anchor block. Ultimately, this ensures that the power generation unit will not undergo large-scale displacement, reducing equipment wear and damage caused by displacement, thereby extending the service life of the photovoltaic power generation system.

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

[0028] like Figures 1-4As shown, a concrete floating platform for a floating photovoltaic power station includes a construction platform 1, which is assembled from multiple panels. The construction platform 1 can float on the water surface. The construction platform 1 has a first float 2 and a second float 11. A rod 5 is connected to each of the first float 2 and the second float 11. A main grounding grid 14 connects the first float 2 and the second float 11, and an indirect grounding grid 15 connects the first float 2 and the second float 11. Multiple anchor blocks 6 are connected to each of the first float 2 and the second float 11. The anchor blocks 6 are assembled from each other and are nested together by a concave-convex design. An anchor rope 7 is connected to each anchor block 6. Anchor blocks 6 are each connected to anchor ropes 7, which are made of nylon. An anchor block 6 is connected to a connecting rod 3 on its side. An actuator 4 is connected to the connecting rod 3. The actuator 4 is hydraulically driven. The end of the anchor block 6 away from the actuator 4 is connected to a base 13. The base 13 is a gravity base. A connecting beam 12 is connected to the base 13. The end of the connecting beam 12 away from the base 13 is connected to a connecting frame 10. The connecting frame 10 and the connecting beam 12 form a V-shaped structure. The end of the connecting frame 10 away from the connecting beam 12 is connected to a bracket 9, which is made of stainless steel. The end of the bracket 9 away from the connecting frame 10 is connected to a floating platform anchoring 8.

[0029] The working principle of this utility model is as follows: The floating platform is composed of a construction platform 1 made up of multiple panels. This platform can float on the water surface. The construction platform 1 is equipped with two floats, 1 and 2, which are used to support photovoltaic panels and power generation equipment, respectively. Multiple anchor blocks 6 are connected to floats 1 and 2, which are connected by anchor ropes 7 to form an anchoring system. Each anchor block 6 is also connected to a connecting rod 3 on its side. The connecting rod 3 is equipped with a pusher 4 for adjusting the position of the floating platform. The end of the anchor block 6 away from the pusher 4 is connected to a base 13. A connecting beam 12 is connected to the base 13. The floating platform anchoring 8 is located at one end of the support 9 and is used to fix the floating platform on the water surface. When the photovoltaic power station needs to be installed or maintained, the construction platform 1 can float to the designated position. With the anchoring effect of anchor block 6 and anchor rope 7, the floating platform can be stably fixed on the water surface to prevent it from moving due to wind or water flow. The thruster 4 can be used to adjust the position of the floating platform to ensure that the photovoltaic panels can obtain the best sunlight conditions. After the photovoltaic panels are installed, the main grounding grid 14 and indirect grounding grid 15 on the floating platform will safely introduce the electricity generated by the photovoltaic power generation into the ground system. Due to the design of the floating platform, the installation and maintenance of the photovoltaic panels become relatively easy, because the staff can operate directly on the floating platform. The anchoring system ensures the stability of the floating platform during operation and can keep its position unchanged even in strong winds or waves. This concrete floating platform design aims to provide a stable and safe environment for the installation, operation and maintenance of photovoltaic power stations.

[0030] By conducting stress analysis on the photovoltaic power generation units, concrete blocks are placed around the array to prevent wind and wave surges in the horizontal direction. This is achieved by using the adhesion and friction between the bottom of anchor block 6 and the bottom silt. In the vertical direction, the weight of anchor block 6 restrains the buoyancy of the array, ultimately ensuring that the power generation units do not experience large-scale displacement. Depending on the water depth, corresponding steel cables are cut from the prefabricated platform. The anchoring vessel establishes a network coordinate system on the water surface, imports the anchoring point location into the intelligent positioning system, and arrives at the anchoring point with a Beidou high-precision RTK positioning device. The anchor block 6 transport vessel loads anchor blocks 6 from the shore and enters the anchoring area. The anchoring vessel is guided to the vicinity of anchor block 6 for anchoring operations. A virtual 3D model is created using BIM technology. The model is then used to extract data and conduct detailed analysis and prediction of various aspects of the floating body and support 9, including structural strength, energy efficiency, and construction process. A concrete floating platform with EPS molded polystyrene board as the core is surrounded by reinforced concrete layers on the sides and top to form a split floating platform that can provide buoyancy. After being assembled in modular sections, it serves as the foundation for electrical equipment. The photovoltaic inverter mounting base 13 is improved, which enhances the heat dissipation efficiency of the string inverter and ensures the safe operation of the equipment. "V"-shaped anchor bolts are used to connect the transformer floating platform to the photovoltaic array floating body, which improves the stability of the system. The cable is laid in an "S" shape on the floating body channel, and the extensibility of the "S"-shaped structure ensures that the cable margin can be adjusted automatically under surge action.

[0031] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
