Description

Technical Field

[0001] This utility model belongs to the field of solar photovoltaic module installation technology, specifically relating to a bridging device for solar modules, which can be widely used in the fixed installation of solar modules in various solar photovoltaic power stations, distributed solar power generation systems and other scenarios. Background Technology

[0002] In the actual installation and application of solar photovoltaic modules, the traditional fixing method generally adopts single-point connection and fixation at the edge of the solar module. This fixing method has obvious defects: the weight of the solar module itself and the external loads it bears during use (such as snow load, dust load, etc.) can only be transferred through the single-point connection at the edge. Under long-term concentrated stress, it is very easy to cause cracking and damage at the connection point, and it can also cause hidden cracks inside the solar module, seriously affecting the service life and power generation performance of the solar module. In addition, when the solar module is subjected to large wind loads, the stability of the single-point connection is insufficient, and the connection point is prone to loosening, further reducing the safety and reliability of the solar module installation structure.

[0003] Therefore, there is an urgent need to design a briquetting device with a reasonable structure, convenient installation, uniform pressure, and applicability to various installation scenarios to solve the above-mentioned problems of existing technologies. Utility Model Content

[0004] The purpose of this invention is to overcome the defects of existing solar module fixing methods and provide a pressure block device for solar modules, which can achieve uniform pressure fixing of solar modules, reduce the risk of cracking at connection points and hidden cracks inside the modules, improve the stability of the installation structure, and meet the usage requirements of various installation scenarios.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a pressing device for solar modules, including a side pressing block, a middle pressing block, a connecting piece, a wire rope clamp, ordinary bolts, and anti-loosening bolts. The ordinary bolt includes a screw rod, a circular washer, a spring washer, and a nut. The screw rod passes through bolt holes opened on both sides of the middle of the side pressing block or middle pressing block, the connecting piece, and the wire rope clamp in sequence. After passing through the bolt holes, the screw rod is fitted with a circular washer and a spring washer in sequence, and the connection is fastened by the nut. The anti-detachment bolt includes an anti-detachment screw, an anti-detachment nut, an anti-detachment circular washer, and an anti-detachment spring washer. The anti-detachment screw passes through the mounting holes opened on the solar panel and the connecting piece in sequence. After passing through the mounting holes, the anti-detachment screw is fitted with the anti-detachment circular washer and the anti-detachment spring washer in sequence, and is fastened by the anti-detachment nut.

[0006] In one embodiment, the edge pressure block is a semi-open Z-shaped pressure plate, the middle pressure block is a Z-shaped pressure plate, and the connecting piece is a Z-shaped connecting piece.

[0007] In one embodiment, bolt holes are provided on both sides of the corresponding positions of the side pressure block, the middle pressure block, and the connecting piece.

[0008] In one embodiment, mounting holes are provided on both sides of the front part of the connecting piece, and the mounting holes are straight groove structures; the mounting holes are adapted to the mounting holes on the solar module so that the anti-loosening bolts can be accurately passed through for fastening connection.

[0009] In one embodiment, the wire rope clamp is tightly connected to the side pressure block or middle pressure block and connecting plate by ordinary bolts, so that the various components are combined together to form an integral structure.

[0010] In one embodiment, the side pressure block, the middle pressure block, the connecting plate, and the wire rope clamp are all made of 2-3mm thick steel plate; the connecting plate is 80-110mm long and 80-110mm wide; the pressure plates of the side pressure block and the middle pressure block are 80-110mm long, 45-60mm wide, and 20-30mm high; and the wire rope clamp is 75-105mm long and 30-40mm wide.

[0011] This utility model has the following beneficial effects: This invention achieves uniform compression of solar modules by using a combination of edge pressure blocks and center pressure blocks, effectively avoiding edge cracking and internal hidden cracks caused by single-point stress.

[0012] This utility model uses anti-loosening bolts (including anti-loosening screws, anti-loosening nuts and matching washers) to tightly fix the solar modules and connecting plates. Combined with the reinforcement effect of steel wire rope clamps on the overall structure, it can limit the longitudinal and horizontal displacement of the solar modules, greatly reducing the probability of the modules loosening, overturning and being damaged due to wind vibration. It is especially suitable for outdoor photovoltaic installation scenarios with strong winds.

[0013] The straight groove design on the connecting piece of this utility model allows for position adjustment within a certain range, making it suitable for solar modules of various specifications and installation methods, improving installation efficiency and compatibility; the anti-loosening bolt, together with the anti-loosening washer and nut, effectively prevents the bolt from loosening due to vibration or temperature changes, ensuring long-term reliability.
