Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panels, in particular to a bottom reinforcement of a photovoltaic panel. Background Art

[0002] As the global energy structure transitions to clean energy, ocean energy, as a renewable resource, is gaining increasing attention. In response to national initiatives to vigorously develop the marine photovoltaic industry and integrate it with the marine aquaculture industry, our company has designed and developed an HDPE (high-density polyethylene) floating fish-photovoltaic complementary platform.

[0003] "Fish-photovoltaic complementarity" refers to a form of combining fishery farming with photovoltaic power generation, that is, photovoltaic panels are set up above the water surface to generate electricity, and seafood is farmed in the waters below the photovoltaic panels. The photovoltaic panel array also provides a good shielding effect for the farmed seafood, forming a new power generation model of "power generation above and farming below"; the fishery-photovoltaic complementarity development model integrates fishery farming, production and processing; utilizing my country's rich marine resources, photovoltaic power generation systems are built in the deep sea, and modern facilities are used to assemble and support fisheries underwater, which not only increases the output value of marine resources, but also the photovoltaic power generation in the upper space can provide green electricity for nearby industry, commerce and seafood processing industries.

[0004] Currently, existing photovoltaic panels are usually bolted or welded with pillars at the bottom of the photovoltaic panels during installation to support the photovoltaic panels. However, due to the changeable marine environment and strong winds and waves, the pillars are prone to shaking, affecting the stability of the photovoltaic panels. Therefore, it is necessary to provide tension reinforcement at the bottom of the photovoltaic panels. Utility Model Content

[0005] The purpose of the present invention is to provide a bottom reinforcement for a photovoltaic panel to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: the bottom reinforcement of the photovoltaic panel includes a reinforcement plate, both ends of the reinforcement plate are provided with buckling grooves, and both side surfaces of the reinforcement plate are provided with multiple ventilation holes, and arc-shaped protrusions are provided at both ends of the reinforcement plate and above and below the buckling grooves, and a fixing piece is fixed on the reinforcement plate; a connecting diagonal rod is connected to the fixing piece, a socket is provided on the fixing piece, and a fixing hole is provided on the connecting diagonal rod, and a fastening bolt is inserted into the socket, and the fastening bolt passes through the socket and the fixing hole and is threadedly connected with a nut. By providing ventilation holes on the reinforcement plate, the air circulation of the reinforcement plate can be effectively increased, which is conducive to air exchange on the back of the photovoltaic panel, thereby reducing the working temperature of the photovoltaic panel and improving the power generation efficiency. At the same time, it can also reduce the pressure of wind on the photovoltaic panel. By allowing air to pass through, the direct effect of wind pressure on the photovoltaic panel is reduced, thereby improving the stability of the photovoltaic system.

[0007] Preferably, the ribbed plate is made by carving a HDPE extruded plate. The HDPE material has the characteristics of high strength and corrosion resistance, which can ensure durability under long-term exposure to outdoor environment, greatly improving the service life of the ribbed plate.

[0008] Preferably, the edges and corners of the ribbed plate and the connecting diagonal rod are rounded, and the arc-shaped protrusions opened by the ribbed plate and the edges and corners of the connecting diagonal rod are rounded, which can avoid causing harm to installers or maintenance personnel.

[0009] Preferably, a mounting hole is provided on the connecting diagonal rod, and the mounting hole is used for connecting the column and the connecting diagonal rod and installing the stiffener plate. By removing the bolt assembly in the mounting hole on the connecting diagonal rod, and then removing the fastening bolts and nuts on the fixing parts on the stiffener plate, the connection between the connecting diagonal rod and the stiffener plate is released, and the connecting diagonal rod and the stiffener plate can be quickly disassembled, which is convenient for quick replacement in case of damage, without replacing the entire photovoltaic panel system.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1) The bottom reinforcement of the photovoltaic panel, through the setting of the reinforcement plate and the connecting diagonal rod, enables multiple columns at the bottom of the photovoltaic panel bracket to be connected to each other, effectively improving the overall structural strength and wind pressure resistance of the photovoltaic bracket, while helping the photovoltaic panel to more evenly bear the load from all directions and improve the stability of the photovoltaic system.

[0012] 2) The bottom reinforcement of the photovoltaic panel is quickly disassembled by removing the bolt assembly in the mounting hole on the connecting diagonal rod, and then removing the fastening bolts and nuts on the fixing parts on the reinforcement plate to release the connection between the connecting diagonal rod and the reinforcement plate, so that the connecting diagonal rod and the reinforcement plate can be quickly replaced when damaged, without replacing the entire photovoltaic panel system. The arc-shaped protrusions on the reinforcement plate and the corners of the connecting diagonal rod are rounded to avoid injury to installers or maintenance personnel.

[0013] 3) The bottom reinforcement of the photovoltaic panel can effectively increase the air circulation of the reinforcement plate by opening ventilation holes on the reinforcement plate, which helps to exchange air on the back of the photovoltaic panel, thereby reducing the operating temperature of the photovoltaic panel and improving the power generation efficiency. At the same time, it can also reduce the pressure of wind on the photovoltaic panel. By allowing air to pass through, the direct effect of wind pressure on the photovoltaic panel is reduced, thereby improving the stability of the photovoltaic system.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Combine Figures 1-4 The bottom reinforcement of the photovoltaic panel includes a reinforcement plate 1, which is made of a carved HDPE extruded plate. Both ends of the reinforcement plate 1 are provided with buckle grooves 2, and both side surfaces of the reinforcement plate 1 are provided with multiple ventilation holes 4. Arc-shaped protrusions 3 are provided at both ends of the reinforcement plate 1 and above and below the buckle grooves 2. A fixing part 5 is fixed on the reinforcement plate 1.

[0021] Specifically, by setting the tie plate 1, multiple columns at the bottom of the photovoltaic panel bracket can be connected to each other, effectively improving the overall structural strength and wind pressure resistance of the photovoltaic bracket, while helping the photovoltaic panel to bear loads from all directions more evenly, thereby improving the stability of the photovoltaic system; by providing ventilation holes 4 on the tie plate 1, the air circulation of the tie plate 1 can be effectively increased, which helps to exchange air on the back of the photovoltaic panel, thereby reducing the operating temperature of the photovoltaic panel and improving the power generation efficiency. At the same time, it can also reduce the pressure of wind on the photovoltaic panel, and by allowing air to pass through, reduce the direct effect of wind pressure on the photovoltaic panel, thereby improving the stability of the photovoltaic system.

[0022] See Figure 2 and Figure 3, it is further obtained that a connecting diagonal rod 9 is connected to the fixing part 5, a socket 6 is opened on the fixing part 5, a fixing hole 10 is opened on the connecting diagonal rod 9, a fastening bolt 7 is inserted in the socket 6, the fastening bolt 7 passes through the socket 6 and the fixing hole 10 and is threadedly connected with a nut 8, the edges and corners of the ribbed plate 1 and the connecting diagonal rod 9 are rounded, and a mounting hole 11 is opened on the connecting diagonal rod 9, which is used for connecting the column and the connecting diagonal rod 9 and installing the ribbed plate 1.

[0023] Specifically, by disassembling the bolt assembly in the mounting hole 11 on the connecting diagonal rod 9, and then disassembling the fastening bolts 7 and nuts 8 on the fixing part 5 on the stiffening plate 1, the connection between the connecting diagonal rod 9 and the stiffening plate 1 is released, and the connecting diagonal rod 9 and the stiffening plate 1 can be quickly disassembled, so that they can be quickly replaced when damaged, without replacing the entire photovoltaic panel system, and the arc-shaped protrusion 3 on the stiffening plate 1 and the corners of the connecting diagonal rod 9 are rounded to avoid injury to installers or maintenance personnel.

[0024] In actual operation, the buckle groove 2 on the ribbed plate 1 is used to buckle the ribbed plate 1 between the two pillars at the bottom of the photovoltaic panel support. The connecting diagonal rod 9 on the ribbed plate 1 is docked with the connecting piece on the pillar. Then, the bolt assembly is passed through the mounting hole 11 on the connecting diagonal rod 9 to tighten the connecting diagonal rod 9, completing the quick installation of the ribbed plate 1.

[0025] When the stiffening plate 1 needs to be disassembled for repair and replacement, the bolt assembly in the mounting hole 11 on the connecting diagonal rod 9 is removed, and then the fastening bolts 7 and nuts 8 on the fixing parts 5 on the stiffening plate 1 are removed to release the connection between the connecting diagonal rod 9 and the stiffening plate 1. After that, the connecting diagonal rod 9 and the stiffening plate 1 can be quickly disassembled, which is convenient for rapid replacement in case of damage, without having to replace the entire photovoltaic panel system;

[0026] When in use, the taut plate 1 can connect to multiple columns at the bottom of the photovoltaic panel bracket, thereby improving the overall structural strength and wind pressure resistance of the photovoltaic bracket, enabling the photovoltaic panel to more evenly bear loads from all directions, and improving the stability of the photovoltaic system. The ventilation holes 4 opened on the taut plate 1 can effectively increase the air circulation of the taut plate 1, which helps to exchange air on the back of the photovoltaic panel, thereby reducing the operating temperature of the photovoltaic panel and improving the power generation efficiency. At the same time, it can also reduce the pressure of wind on the photovoltaic panel. By allowing air to pass through, the direct effect of wind pressure on the photovoltaic panel is reduced, thereby improving the stability of the photovoltaic system.
