Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support module technology, and in particular to a photovoltaic support and purlin fixing device. Background Technology

[0002] Currently, most photovoltaic brackets on the market use purlins with a U-shaped cross section and clamps for fixing purlins and main beams. However, the bottom of the U-shaped purlin is a flat plate. If the installation surface of the main beam is short, such as on a main beam with large rounded corners or a polygonal main beam, the contact surface length between the two is short, resulting in poor fixing effect. Therefore, it is necessary to add components between the main beam and the purlin to strengthen the fixing effect.

[0003] Existing technical solutions, such as the patent with publication number CN 221202402 U, disclose a purlin structure and photovoltaic bracket. The purlin is used to install photovoltaic modules; the reinforcing frame includes a support part located outside the purlin body. Along the length of the main beam, one end of the support part abuts against the side wall of the purlin body, and the other end abuts against the main beam; a connector is used to fix the purlin body to the main beam. Although the existing technical solution can effectively fix the purlin to the main beam, the support part and connector still need to be installed between the purlin and the main beam, resulting in a large number of parts required for fixing the purlin and the main beam, which is inconvenient to install and reduces the efficiency of on-site construction.

[0004] Therefore, it is necessary to design a photovoltaic support structure and purlin fixing device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a photovoltaic bracket and purlin fixing device to overcome the above-mentioned shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A photovoltaic bracket and purlin fixing device are disclosed, comprising a main beam for fixing photovoltaic modules, a purlin fixing device for installing the main beam, and a photovoltaic module for mounting the purlin body. The purlin fixing device includes an integrally formed purlin body bracket and U-bolts for mounting the purlin body bracket. The purlin body bracket includes a main purlin plane, a main beam mating plane extending downwards from both sides of the main purlin plane for mounting the main beam, and supporting arc surfaces extending outwards along both sides of the main beam mating plane for supporting and fixing the photovoltaic modules. A main beam conforming arc surface is provided on the side of the main beam mating plane that is in contact with the main beam, and a main beam mating arc surface extends outwards along the main beam conforming arc surface of the main beam mating plane.

[0008] Preferably, the purlin body support has a convex shape when viewed from the side and an M-shaped structure when viewed from the front.

[0009] Preferably, the shape of the contoured arc surface of the main beam is the same as the shape of the outer surface structure of the main beam.

[0010] Preferably, there are multiple sets of reinforcing ribs on the supporting arc surface and the main purlin plane.

[0011] Preferably, mounting holes are also provided on the supporting arc surface.

[0012] Preferably, a fixing hole for fixing with a U-bolt is provided on the plane of the main purlin.

[0013] The beneficial effects of this utility model are as follows: This technical solution sets up an integrated purlin body support, which fits the shapes of the purlin and the main beam together, and fixes them together with U-bolts. Compared with the prior art, this utility model reduces the number of parts of the purlin device, increases the installation speed of the purlin and the main beam, reduces the maintenance and repair costs of the photovoltaic support, and increases the revenue of the photovoltaic power station.

[0018] Reference Figures 1 to 3 A photovoltaic bracket and purlin fixing device includes a main beam 1 for fixing photovoltaic modules, a purlin fixing device 2 for installing with the main beam, and a photovoltaic module 3 for mounting the purlin body.

[0019] The purlin fixing device includes an integrally formed purlin body bracket 4 and U-bolts 5 that are installed in conjunction with the purlin body bracket;

[0020] The purlin body support has a convex shape when viewed from the side, and an M-shaped structure when viewed from the front.

[0021] In order to achieve rapid assembly and to support the photovoltaic module 3, the purlin body support 3 includes a main purlin plane 21, a main beam mating plane 22 arranged downward from both sides of the main purlin plane 21 for main beam installation, and a supporting arc surface 23 extending outward from both sides of the main beam mating plane 22 to support and fix the photovoltaic module 3.

[0022] The side of the main beam that is in contact with the main beam is provided with a main beam conforming arc surface 24, the shape of which is the same as the outer surface structure of the main beam; thus, the entire structure can be quickly fitted to the main beam, achieving the effect of rapid installation.

[0023] To increase the overall support strength and ensure the support force, a main beam fitting arc surface 25 is provided extending outward along the main beam fitting plane. By extending the main beam fitting arc surface 25 outward, the contact area with the main beam support is increased, thereby increasing the stress area and improving the load-bearing capacity, ensuring the stability of the photovoltaic panel after installation.

[0024] Multiple sets of reinforcing ribs 231 are provided on the supporting arc surface 23 and the main purlin plane 21. The reinforcing ribs 231 improve the overall strength of the supporting arc surface 23, enabling it to withstand more force. Mounting holes 232 are also provided on the supporting arc surface 23. The supporting arc surface 23 is used to place or support the photovoltaic module 3, and the mounting holes 232 are used to fix the photovoltaic module 3 together, strengthening the connection strength of the two supports, thereby enabling quick connection.

[0025] To facilitate installation, a fixing hole 211 is provided on the main purlin plane 21 for fixing with U-bolts. The U-bolt is installed by fitting it into the fixing hole 211 on the main purlin plane 21, and then fixed with a washer and nut to fix it to the main beam.

[0026] The main beam 1 is a thin-walled structure with a large rounded rectangular cross-section.

[0027] In this implementation, the purlin body bracket 4 is placed on the upper surface of the main beam 1, and the contoured arc surface 24 of the main beam is fitted to the upper surface of the main beam 1. After the fitting is completed, U-bolts 5 are inserted from the bottom of the main beam 1 to wrap around the main beam 1 and are installed in conjunction with the purlin body bracket 4. The two ends of the U-bolts 4 are inserted into the fixing holes 211 on both sides of the main purlin plane 21, and are fixed by nuts and washers. This completes the fixed installation between the purlin body bracket 4 and the main beam 1. At least two sets of purlin body brackets 4 are installed according to the gap of the photovoltaic modules. Specifically, the position can be adjusted by loosening the nuts of the U-bolts 4. The two bottom surfaces of the photovoltaic modules are placed on the plane of the supporting arc surface 23, and then fixed by nuts and bolts in conjunction with the mounting holes on the supporting arc surface 23 to quickly achieve fixation and complete the initial assembly.

[0028] The advantages of this utility model are that by setting an integrated purlin body support, the shapes of the purlin and the main beam are matched together and fixed by U-bolts, which reduces the number of parts of the purlin device, improves the installation speed of the purlin and the main beam, reduces the maintenance and repair costs of the photovoltaic support, and increases the revenue of the photovoltaic power station.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
