Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, and particularly relates to a hinge piece for a photovoltaic bracket. Background Art

[0002] Photovoltaic modules are an important part of solar power generation. Through photovoltaic cells made of semiconductor materials inside the photovoltaic modules, light energy is converted into electrical energy to complete the operation of solar power generation. In order to improve the sunlight absorption effect of photovoltaic modules and the utilization of solar energy resources, photovoltaic modules are generally installed on building roofs. Therefore, metal brackets are needed to fix the photovoltaic modules. For different house types, the specific solutions can be divided into "array type, hook type, and overhead type". For the "overhead type" bracket installation form, the wall bracket support is fixed using hinge pieces.

[0003] When the existing hinge piece is hinged with the photovoltaic bracket, the bolts are usually exposed. In rainy weather, rainwater will flow along the hinge piece to the bolts at the hinge. The rainwater will corrode the bolts. In the long term, on the one hand, it will affect the subsequent disassembly of the bolts, and on the other hand, it will pose a hidden danger to the firmness and safety of the hinge. Therefore, we propose a hinge piece for a photovoltaic bracket to solve the above problems. Summary of the Utility Model

[0004] The utility model provides a hinge piece for a photovoltaic bracket, which solves the technical problem that the bolts are corroded by rainwater when the existing hinge piece is hinged with the photovoltaic bracket, resulting in a reduction in fixing safety.

[0005] To solve the above technical problems, a hinge piece for a photovoltaic bracket provided by the utility model includes a hinge piece body vertically fixed on a wall surface and a bracket body hinged with the hinge piece body. The hinge piece body further includes a fixing plate. Hinge plates are fixed on both sides of the fixing plate. Waterproof covers are obliquely fixed on both sides of the hinge plates. The two sides of the waterproof covers extend outwards beyond the hinge plates. The top of the waterproof covers is hermetically connected to the fixing plate. Hinge holes are formed on both sides of the hinge plates. Waterproof ring sleeves are fixed on the outer sides of both sides of the hinge plates. Waterproof plugs are arranged on the waterproof ring sleeves.

[0006] Preferably, mounting holes are formed on the fixing plate. Two mounting holes are formed and are symmetrically distributed on the fixing plate.

[0007] Adopting the above technical solution: By forming mounting holes on the fixing plate, and two mounting holes are formed and are symmetrically distributed on the fixing plate, it is convenient to fix the hinge piece body on the wall surface through expansion bolts.

[0008] Preferably, the mounting holes are in a long strip shape, and both ends of the mounting holes are arc-shaped.

[0009] Adopt the above technical solution: Since the mounting holes are strip-shaped and the two ends of the mounting holes are arc-shaped, the expansion bolts can adjust the appropriate mounting positions in the strip-shaped mounting holes.

[0010] Preferably, the waterproof ring sleeve is fixed on the hinge plate with the hinge hole as the same central axis.

[0011] Adopt the above technical solution: Since the waterproof ring sleeve is fixed on the hinge plate with the hinge hole as the same central axis, the waterproof ring sleeve can protect the hinge bolts from being eroded by rainwater.

[0012] Preferably, expansion bolts are provided on the hinge part body. One end of the expansion bolt fixes the hinge part body, and the end of the expansion bolt away from the hinge part body is inserted and fixed in the wall after expansion.

[0013] Adopt the above technical solution: Since expansion bolts are provided on the hinge part body, one end of the expansion bolt fixes the hinge part body, and the end of the expansion bolt away from the hinge part body is inserted and fixed in the wall after expansion. The expansion bolts can fix the hinge part on the wall, and the part of the hinge part away from the wall is hinged to the photovoltaic bracket body.

[0014] Preferably, hinge bolts are provided in the hinge holes. The hinge bolts hinge the bracket body and the hinge part body, and both ends of the hinge bolts are hexagonal.

[0015] Adopt the above technical solution: Since hinge bolts are provided in the hinge holes, the hinge bolts hinge the bracket body and the hinge part body, and both ends of the hinge bolts are hexagonal. The hexagonal shape is a common bolt on the market, which is convenient for the later installation and replacement of the hinge bolts between the hinge part and the photovoltaic bracket body.

[0016] Preferably, the diameter of the waterproof ring sleeve is larger than the diameter of the hinge hole.

[0017] Adopt the above technical solution: Since the diameter of the waterproof ring sleeve is larger than the diameter of the hinge hole, the waterproof ring sleeve can protect the hinge bolts inside the waterproof ring sleeve from being eroded by rainwater.

[0018] Compared with the related art, the utility model has the following beneficial effects:

[0019] 1. Compared with traditional photovoltaic bracket hinge parts, the utility model is provided with a waterproof cover plate, a waterproof ring sleeve and a waterproof plug. The waterproof cover plate is fixedly inclined on both sides of the hinge plates. The two sides of the waterproof cover plate extend outwards from the hinge plates, and the top of the waterproof cover plate is hermetically connected to the fixed plate. Hinge holes are provided on both sides of the hinge plates, and waterproof ring sleeves are fixed on the outer sides of both sides of the hinge plates. Waterproof plugs are arranged on the waterproof ring sleeves. When it rains, the rainwater hits the inclined waterproof cover plate, and the rainwater drips onto the ground along the inclined waterproof cover plate, preventing the bolts inside the hinge parts from being corroded by rainwater. At the same time, a waterproof ring sleeve is arranged at the hinge joint between the hinge part body and the photovoltaic bracket body, and the outside of the waterproof ring sleeve is blocked with a waterproof plug, which can prevent the hinge bolts inside the waterproof ring sleeve from being corroded by rainwater, avoiding various losses caused by inconvenient disassembly of the bracket body and reduced firmness of the hinge due to long-term corrosion, enhancing the practicability and the service life of the hinge between the bracket body and the hinge part.
