Description

Technical Field

[0001] The invention belongs to the technical field of solar energy application, and in particular relates to a pressing block and an installation structure of a photovoltaic component using the pressing block. Background Art

[0002] Photovoltaic modules are generally composed of photovoltaic arrays to generate electricity. Most existing photovoltaic modules are installed on the bracket by aluminum blocks + bolts. A set of blocks needs to be pressed together with the edges of two adjacent modules at the same time. In the actual construction process, the positions of the two adjacent modules need to be placed at the same time before the bolts can be tightened to tighten the blocks. This requires multiple people to coordinate the construction, which is time-consuming and labor-intensive, and it is inconvenient to repair and replace individual modules in the array later. Summary of the invention

[0003] The purpose of the present invention is to provide a pressing block and a photovoltaic module installation structure using the pressing block, so as to make the photovoltaic module more convenient to install and disassemble.

[0004] The pressing block of the present invention includes a main body in a groove structure, the ends of the groove walls on both sides of the main body are bent parts, the middle parts of the groove walls on both sides are provided with a hollow part, and the hollow part is provided with a guide rail barb, one end of the guide rail barb is integrally connected to the groove wall, and the other end extends toward the central axis of the main body and the groove bottom direction; one end of the outer wall of the groove bottom of the main body is provided with a frame barb, one end of the frame barb is integrally connected to the main body, and the other end extends toward the middle of the main body and the groove bottom direction of the main body.

[0005] The installation structure of the photovoltaic assembly using the above-mentioned pressing block is as follows: it includes a guide rail, a photovoltaic assembly and a pressing block, the frame of the photovoltaic assembly is clamped between the frame barbs and the outer wall of the groove bottom of the pressing block body, the two side groove walls of the body are clamped on the two sides of the guide rail, and the guide rail barbs are pressed against the side of the guide rail.

[0006] When installing a photovoltaic module, first install the pressing block on the module so that the frame barb structure on the pressing block is tightly stuck on the module frame, and then press the pressing block on the guide rail, and use the bent portion of the pressing block to cooperate with the guide rail barb to clamp the guide rail. In this way, there is no need to fix the module with bolts, which reduces installation costs and improves installation efficiency. Since this structure is fixed to a single module alone, it is convenient for subsequent disassembly, maintenance or replacement of the single module without disassembling the entire array.

[0007] Further, the bending portion is composed of a first fold and a second fold, one end of the first fold is integrally connected to the groove wall, and the other end is integrally connected to the second fold, the bending direction of the first fold is to gradually bend toward the central axis of the body along the groove wall end to the second fold end, and the bending direction of the second fold is opposite to the bending direction of the first fold. Both sides of the guide rail are provided with inwardly concave recesses, the end of the second fold abuts against the bottom wall of the recess, the end of the guide rail barb abuts against the top wall of the recess, and the junction of the first fold and the second fold abuts against the inner wall of the recess. The second fold and the guide rail barb limit the pressure block in two opposite directions respectively, which can prevent the pressure block from detaching from the guide rail, and the junction of the first fold and the second fold abuts against the inner wall of the recess, which can clamp the guide rail to prevent the pressure block from moving along the guide rail.

[0008] Furthermore, in order to improve the limiting effect, the guide rail barbs, the frame barbs, and the ends of the second folded edge are all provided with protruding spike structures.

[0009] Furthermore, a third folded edge is provided on the outer wall of the groove bottom of the main body beside the frame barb, and the third folded edge and the groove bottom of the main body form a U-shaped structure; the frame of the photovoltaic component is clamped between the third folded edge and the outer wall of the groove bottom of the pressing block body, and the third folded edge can prevent the photovoltaic component from being separated from the pressing block along the direction perpendicular to the groove bottom of the pressing block body. Combined with the frame barb limiting the photovoltaic component along the groove bottom direction of the pressing block body, the photovoltaic component can be limited in the horizontal and vertical directions, thereby ensuring the stable combination of the photovoltaic component and the pressing block.

[0010] Furthermore, in order to reduce the cost and improve the connection stability between the various structures of the pressing block, the pressing block is made of a metal plate or a plastic plate in one piece.

[0011] The pressing block of the present invention has a simple structure and low cost. It can conveniently and reliably install the photovoltaic module on the guide rail without the need for bolts, nuts and other parts, thereby improving installation efficiency, reducing installation costs, and facilitating subsequent maintenance or replacement of the photovoltaic module.

[0020] The following is a detailed description of the specific implementation of the present invention, such as the shape, structure, relative position and connection relationship of each component involved, the function and working principle of each component, etc., through the description of the implementation examples with reference to the accompanying drawings.

[0021] Embodiment 1:

[0022] This embodiment provides a pressing block and a photovoltaic module installation structure using the pressing block, so as to facilitate the assembly and disassembly of the photovoltaic module.

[0023] like Figures 1 to 4 As shown, the pressing block of this embodiment includes a main body 1 with a groove structure, and the ends of the groove walls on both sides of the main body 1 are bending parts, which are composed of a first folded edge 2 and a second folded edge 3. One end of the first folded edge 2 is integrally connected to the groove wall, and the other end is integrally connected to the second folded edge 3. The bending direction of the first folded edge 2 is along the groove wall end to the direction of the second folded edge 3 and gradually bends toward the central axis of the main body 1. The bending direction of the second folded edge 3 is opposite to the bending direction of the first folded edge 2.

[0024] A hollow portion is provided in the middle of the groove wall on both sides of the body 1, and a guide rail barb 4 is provided at the hollow portion, one end of the guide rail barb 4 is integrally connected to the groove wall, and the other end extends toward the central axis of the body 1 and the groove bottom direction; a frame barb 5 is provided at one end of the outer wall of the groove bottom of the body 1, one end of the frame barb 5 is integrally connected to the body 1, and the other end extends toward the middle of the body 1 and the groove bottom direction of the body 1. The outer wall of the groove bottom of the body 1 is provided with a third folded edge 6 on both sides of the frame barb 5, and the third folded edge 6 is nearly parallel to the groove bottom of the body 1 to form a U-shaped structure; the ends of the guide rail barb 4, the frame barb 5, and the second folded edge 3 are all provided with protruding spike structures.

[0025] In order to reduce the cost and improve the connection stability between the various structures of the pressing block, the pressing block is made of a metal plate in one piece through processes such as stamping and bending.

[0026] like Figure 5 , 6 As shown in Figures 7, the installation structure of the photovoltaic assembly using the above-mentioned pressing block in this embodiment includes a pressing block 10, a guide rail 20 and a photovoltaic assembly 30, wherein both sides of the guide rail 20 are provided with inwardly recessed recesses 21, and the frame 31 of the photovoltaic assembly 30 is clamped between the third folded edge 6 and the outer wall of the groove bottom of the pressing block 10 body 1, and is clamped between the frame 31 barbs 5 and the outer wall of the groove bottom of the pressing block 10 body 1. The above-mentioned third folded edge 6 can prevent the photovoltaic assembly 30 from being separated from the pressing block 10 along the direction perpendicular to the groove bottom of the pressing block 10 body 1. Combined with the frame 31 barbs 5 limiting the photovoltaic assembly 30 along the groove bottom direction of the pressing block 10 body 1, the photovoltaic assembly 30 can be limited in the horizontal and vertical directions, thereby ensuring that the photovoltaic assembly 30 and the pressing block 10 are firmly combined.

[0027] The groove walls on both sides of the body 1 are clamped on both sides of the guide rail 20, and the guide rail barbs 4 are pressed against the side of the guide rail 20. Specifically, the end of the second folded edge 3 abuts against the bottom wall of the recess 21, the end of the guide rail barbs 4 abuts against the top wall of the recess 21, and the junction of the first folded edge 2 and the second folded edge 3 abuts against the inner wall of the recess 21. The second folded edge 3 and the guide rail barbs 4 limit the pressing block 10 in two opposite directions respectively, which can prevent the pressing block 10 from detaching from the guide rail 20, and the junction of the first folded edge 2 and the second folded edge 3 abuts against the inner wall of the recess 21, which can clamp the guide rail 20 and prevent the pressing block 10 from moving along the guide rail 20.

[0028] When installing the photovoltaic module 30, first install the pressing block 10 on the module so that the barb 5 structure of the frame 31 on the pressing block 10 is tightly stuck on the module frame 31, and then press the pressing block 10 on the guide rail 20, and use the bending part of the pressing block 10 to cooperate with the barb 4 of the guide rail to clamp the guide rail 20. In this way, there is no need to fix the module with bolts, which reduces the installation cost and improves the installation efficiency. Since this structure is fixed to a single module alone, it is convenient for the subsequent disassembly, maintenance or replacement of the single module without disassembling the entire array.

[0029] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific design of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
