Description

Technical Field

[0001] The utility model relates to the technical field of roof photovoltaic technology, and specifically relates to a mounting bracket for a solar photovoltaic panel. Background Technique

[0002] Solar cells are made of semiconductor materials, usually silicon wafers. When sunlight shines on a photovoltaic cell, photons interact with the semiconductor material in the photovoltaic cell to produce the photovoltaic effect. This causes charges to move in the semiconductor material, thereby generating direct current. A solar photovoltaic panel bracket is a structural framework for installing solar photovoltaic panels, which plays a role in supporting and fixing the solar photovoltaic panels. Existing photovoltaic panels are installed outdoors and on roofs. During the installation of roof photovoltaics, a mounting bracket is used to install the photovoltaic panels on the building roof.

[0003] The photovoltaic system is fixed on the building roof. In addition to causing damage to the building itself, earthquake disasters also have a certain impact on the stability of the roof photovoltaic system. Under strong earthquake action, the connection brackets and components such as photovoltaic panels between the photovoltaic system and the roof are damaged or slip off, resulting in the photovoltaic system being unable to work properly. The structural design of the existing building roof photovoltaic support system should take into account the effects of gravity load, wind load, snow load, dust accumulation load and maintenance load. Considering the special plateau climate environment in Yunnan, in addition to the gravity load, the wind load is the main load form affecting the roof photovoltaic system, making the aerodynamics of installing a photovoltaic array on the roof extremely complex. The photovoltaic panels and photovoltaic brackets may be damaged under strong wind action, which may cause casualties and huge economic losses.

[0004] During the installation of the existing solar photovoltaic panel mounting bracket, the mounting bracket will damage the building roof surface. During the process of fixing the bracket, it is easy to damage the seismic effect of the roof, resulting in an impact on the building. At the same time, when the mounting bracket realizes installation and support, it is not conducive to playing a shock-absorbing role. The vibration will act on the roof surface in the opposite direction. The gravity of the bracket itself and the weight when carrying the solar panel will cause the roof surface to be cracked during the installation and fixing process. During the long-term support installation process, the self-weight of the bracket and the influence of the vibration of the bracket are likely to extend cracks outward from the fixed point on the roof surface, causing damage to the roof surface.

[0005] Therefore, those skilled in the art have provided a mounting bracket for a solar photovoltaic panel to solve the problems raised in the above background technique. Content of the Utility Model

[0006] The purpose of the present utility model is to provide a mounting bracket for a solar photovoltaic panel, so as to solve the problem that in the process of installing a photovoltaic panel with the existing solar photovoltaic panel mounting bracket, the mounting bracket will damage the building roof surface.

[0011] As a further scheme in the present utility model, a bushing is welded to the inner wall of the photovoltaic panel body, a docking rod is inserted into the bushing, and docking nuts are movably sleeved at both ends of the docking rod.

[0012] As a further scheme in the present utility model, the surfaces at both ends of the docking rod are provided with a threaded structure, and the two ends of the docking rod and the docking nuts cooperate with each other to form a threaded connection.

And shock-absorbing rubber pads are arranged at the bottoms of the fixing plates. In this way, when fixing, while increasing the anti-slip property and improving the friction force, soft protection is provided for the roof surface to avoid damaging the roof surface too much during fixing.
