Figure 1 As shown, insert the stainless steel bolt 2 into the aluminum alloy block 4 without tightening the nut, then place the assembly 1 on the upper part of the purlin 3, and finally combine the stainless steel bolt 2 and the aluminum alloy block 4, place the aluminum alloy block 4 on the assembly 1, insert the stainless steel bolt 2 into the corresponding hole of the purlin 3, and finally tighten it with the nut; or as shown Figure 2 As shown, first place the component 1 above the purlin 3 during installation, find the reserved opening on the frame of the component 1, match the reserved opening with the hole on the purlin 3, use the stainless steel bolt 2 to connect the component 1 to the purlin 3, and finally lock it with a nut.
[0004] The above-mentioned prior art solutions have the following defects:
[0005] 1. Two component fixing methods used, Figure 1 Due to the limitation of the number of purlins, the number of aluminum alloy blocks that can be installed is limited; Figure 2 Due to the limitation of the component frame, the number of installed fixing bolts is limited.
[0006] 2. In areas with heavy wind loads, such as the seaside, Figure 1 In order to ensure the firmness of the component installation, a large number of aluminum alloy blocks need to be installed, which results in the need for more purlins to ensure the installation of the aluminum alloy blocks, which is not conducive to cost control and the on-site installation procedure is more complicated; Figure 2 The installation method is that the frame of the component is fixed, and the number of openings reserved in the frame is limited, so the number of connecting bolts will be insufficient, resulting in insufficient pull-out resistance of the connection node, which may cause safety accidents such as the component being overturned by strong winds. Summary of the invention
[0007] The purpose of the present utility model is to address the deficiencies of the above-mentioned background technology and to provide a new photovoltaic module and bracket connection structure, which increases the connection nodes between the photovoltaic module and the purlin, improves the overall stability of the photovoltaic bracket, prevents the module from being overturned under extreme weather conditions, simplifies on-site installation and construction, and can be installed in a wider geographical range.
[0008] The technical solution adopted by the utility model is:
[0009] A novel photovoltaic module and bracket connection structure includes a photovoltaic module, a pressure block, a bolt, a purlin, and a fixing piece. The reserved hole on the photovoltaic module frame is fixed to the hole on the purlin by a bolt. The characteristic is that the structure of the fixing piece is a "7" shape. Two adjacent photovoltaic modules fixed on the purlin are fixed to one side of the fixing piece by a pressure block and another bolt, and the other side of the fixing piece is fixed to the purlin by another bolt.

[0011] The fan-shaped gasket has a semicircular cross section as a whole, a U-shaped side surface, and a waist-shaped hole is formed on the U-shaped bottom plate.
[0012] The overall height of the pressing block needs to be greater than the thickness of the photovoltaic module frame.
[0013] The reserved holes in the purlin web and the holes in the pressure blocks are all elliptical holes, ensuring that there is enough installation space when the stainless steel bolts are inserted obliquely into the reserved holes.
[0014] The beneficial effects of the utility model are:
[0015] When using the utility model, the overall stability of the photovoltaic bracket is improved due to the increase of the connection nodes between the components and the purlins. When using the utility model, the overall stability of the photovoltaic bracket is better due to the increase of the connection nodes, and it can be applied to a wider range of regions, and compared with Figure 1 The utility model does not need to increase the number of connecting aluminum alloy blocks and purlins when adding connection nodes, which not only saves the cost of photovoltaic brackets, but also does not occupy more installation space under the components, making it more convenient for on-site construction and installation; compared with Figure 2 The solution will not be limited by the number of pre-openings in the aluminum alloy frame of the component. By increasing the connection nodes, it can effectively reduce the risk of safety accidents such as components being overturned due to large wind loads in some areas with large wind loads.

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not constitute a limitation on the present invention.
[0026] Embodiment 1:
[0027] like Figure 3 , Figure 4 As shown, a novel photovoltaic module and bracket connection structure of the utility model comprises a photovoltaic module 1, an aluminum alloy pressing block 4, a stainless steel bolt 2, a purlin 3, and a fixing member 5. The reserved holes on the frame of the photovoltaic module 1 and the holes on the purlin 3 are fixed by a stainless steel bolt 2. It is characterized in that the structure of the fixing member 5 is in the shape of a "7", and two adjacent photovoltaic modules 1 fixed on the purlin 3 are fixed to one side of the fixing member 5 by the aluminum alloy pressing block 4 and another stainless steel bolt 2, and the other side of the fixing member 5 is fixed to the purlin 3 by another stainless steel bolt 2.
[0028] The specific installation is as follows: first, place the photovoltaic module 1 above the purlin 3, find the reserved holes in the frame of the photovoltaic module 1, and match the reserved holes in the frame of the photovoltaic module 1 with the holes on the purlin 3, then pre-open holes in the web of the purlin 3, use the "7"-shaped fixing piece 5 to open holes on both sides, install the aluminum alloy pressing block 4 above one side of the fixing piece 5, and connect the other side of the fixing piece 5 to the web of the purlin 3, and finally tighten and lock all the opening positions with stainless steel bolts 2. The utility model is simple to install by adding connection nodes, and is not limited by the number of reserved holes in the aluminum alloy frame of the photovoltaic module.
[0029] Embodiment 2:
[0030] like Figure 5 , Figure 6a , Figure 6b , Figure 6c , Figure 6d As shown, the utility model is a novel photovoltaic module and bracket connection structure, including photovoltaic modules 1, aluminum alloy blocks 4, stainless steel bolts 2, purlins 3, and fan-shaped gaskets 6. The reserved holes of the frame of the photovoltaic module 1 and the holes on the purlins 3 are fixed by a stainless steel bolt 2. It is characterized in that: two adjacent photovoltaic modules 1 fixed on the purlins 3 are fixed to the purlins 3 by the aluminum alloy blocks 4, another stainless steel bolt 2 and two fan-shaped gaskets 6. The two fan-shaped gaskets 6 are respectively placed in parallel at the openings of the aluminum alloy blocks 4 and the webs of the purlins 3. Figure 6a , Figure 6b , Figure 6c , Figure 6d As shown, the overall cross-section of the fan-shaped gasket 6 is semicircular, the side is U-shaped, and a waist-shaped hole is opened on the U-shaped bottom plate. The overall height of the aluminum alloy block 4 needs to be greater than the thickness of the frame of the photovoltaic module 1. The reserved holes of the web of the purlin 3 and the holes of the aluminum alloy block 4 are all elliptical holes to ensure that there is enough installation space when the stainless steel bolt 2 is obliquely inserted into the reserved hole.
[0031] The specific installation is as follows: first, place the photovoltaic module 1 above the purlin 3, find the reserved holes in the frame of the photovoltaic module 1, and match the reserved holes in the frame of the photovoltaic module 1 with the holes on the purlin 3, then pre-open holes in the web of the purlin 3, and use stainless steel bolts 2 to obliquely penetrate the openings of the aluminum alloy pressing block 4 and the pre-openings of the web of the purlin 3. While pressing the adjacent photovoltaic modules 1, the lower end of the aluminum alloy pressing block 4 protrudes from the photovoltaic module and rests on the web of the purlin 3. A fan-shaped gasket 6 is used at both ends of the stainless steel bolt 2, and the fan-shaped gasket 6 is placed parallel to the openings of the aluminum alloy pressing block 4 and the web of the purlin 3. After the stainless steel bolt 2 obliquely penetrates the hole of the aluminum alloy pressing block 4 and the pre-opening of the web of the purlin 3, since the other end of the fan-shaped gasket is arc-shaped, it can ensure that when nuts, spring washers or flat washers are used later, the fan-shaped gasket and the stainless steel bolt are effectively tightened, and the stainless steel bolt will not be unable to be tightened later because the stainless steel bolt is inserted obliquely.
