Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaics, and in particular to a photovoltaic support fixing device. Background Art
[0002] BIPV (Building Integrated PV) and household photovoltaic waterproof roofs will be one of the most effective ways to develop green buildings, effectively reduce building energy consumption, and implement carbon reduction actions.
[0003] A common practice for BIPV and household photovoltaic waterproof roofs is to replace conventional building roofs with photovoltaic roofs. The gaps between roof components are usually sealed with rubber strips or sealants, which is only one waterproof measure, and the rubber strips or sealants have poor weather resistance and are prone to leakage. In order to solve the drawbacks of one waterproof measure, there are currently two waterproof measures. Specifically, that is, a W-shaped water guide groove is used in the gap between components as a structural support and a sealing strip to form two waterproof measures. However, this structure often uses the W-shaped purlin as both a water guide groove and a support, and the water guide groove uses a large amount of steel and the cost remains high.
[0004] The Chinese patent with publication number CN219643823U discloses a connection and fixing device between a bracket and a photovoltaic module and a water channel. The patent separates the bracket and the water channel to reduce the amount of steel used in the water channel. In this structure, there is no support frame on the adjacent side of the adjacent photovoltaic, which is not convenient for ensuring the support strength of the photovoltaic module. In addition, the first water channel requires additional self-tapping screws for assembly, which is not easy to ensure the waterproof effect at the first water channel. Utility Model Content

[0008] The reinforcing support frame is placed in the first water guide groove, and the reinforcing support frame is sandwiched between the photovoltaic module and the bracket;
[0009] The L-shaped pressure plate includes a horizontally arranged transverse plate and a vertically arranged longitudinal plate, the horizontal plate is overlapped on the frame of the photovoltaic module, the horizontal plate is provided with a through hole for the U-shaped bolt to pass through, the U-shaped bolt is sleeved on the periphery of the bracket, the end of the U-shaped bolt is threadedly connected with a locking nut, and a clamping plate passing through the two ends of the U-shaped bolt is sandwiched between the locking nut and the bracket;
[0010] The lower end of the longitudinal plate abuts against the bracket.
[0011] The utility model facilitates the installation of photovoltaic modules on the bracket and ensures waterproof effect by strengthening the combination of the support frame and the L-shaped pressure plate. Through the combination of the U-shaped bolt and the clamping plate, it is unnecessary to punch holes on the bracket, which greatly ensures the support strength of the bracket.
[0012] Further preferably, it further comprises a second water guide groove, wherein the second water guide groove is overlapped on the first water guide groove, and the second water guide groove is directly opposite to the frame of the adjacent photovoltaic assembly along the second straight line direction.
[0013] Further preferably, the length direction of the first water guide groove is parallel to the long side of the photovoltaic module;

[0016] The transverse plate is provided with a stamping groove that butts against two perforations, and the stamping groove is used to limit the U-shaped bolt.
[0017] Further preferably, the bracket is a supporting purlin.
[0018] Further preferably, the reinforcing support frame includes support feet arranged on the opposite sides of the mirror image, and the support feet are connected to both sides of the concave bending portion through a horizontal support portion;

[0022] Beneficial effects:
[0023] The utility model realizes the connection between the bracket, the photovoltaic component and the water guide groove through the connecting piece, avoids the problem that the traditional water guide groove also serves as the bracket, which is neither economical nor easy to maintain and replace later, and further increases the waterproof ability of the photovoltaic roof.
