Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, specifically a wind-resistant ring-type photovoltaic module fixing structure. Background Technology

[0002] In coastal areas with frequent strong winds or mountainous areas with complex terrain and significant local wind speed changes, the existing method of fixing photovoltaic modules during installation typically involves bolting the module frame to the bracket purlins. However, this method often fails to achieve the desired results. Due to the narrow and thin frame of the module and the weakening effect of bolt holes on the frame, the nodes are prone to tearing under frequent strong winds, leading to the module falling and being damaged. This poses certain safety hazards and causes property damage. Summary of the Invention

[0003] To address the aforementioned technical problems, this utility model provides a wind-resistant ring-type photovoltaic module fixing structure, which can improve the installation stability of photovoltaic modules.

[0004] The technical solution is as follows: a wind-resistant ring-type photovoltaic module fixing structure, which includes purlins supporting the photovoltaic module, characterized in that long strip pressure blocks are respectively provided on the four sides of the photovoltaic module, and inverted U-shaped bolts are installed on the purlins to press down the long strip pressure blocks. The two ends of the opening of the inverted U-shaped bolts pass through angle steel connectors and are locked with nuts so that the angle steel connectors abut against the bottom of the purlins.

[0005] A further feature is that the two ends of the angle steel connector are respectively connected to the two ends of the long strip pressure block by flat steel diagonal tie rods;

[0006] The long strip pressing block includes a long strip side pressing block and a long strip middle pressing block. The long strip side pressing block is Z-shaped and presses down on one side of the photovoltaic module. The long strip middle pressing block is U-shaped and has outward pressing strips at both ends of the opening, which are used to press down on one side of each of the two adjacent photovoltaic modules.

[0007] By adopting this utility model, the photovoltaic module is fixed to the purlin through the long strip pressure block, inverted U-shaped bolts and angle steel connectors, which reduces the possibility of the photovoltaic module frame tearing and falling off, and effectively improves the wind resistance of the module. Furthermore, the flat steel diagonal tie rods form a micro-triangular fixing structure with the upper long strip pressure block and the lower angle steel connectors, which greatly improves the outward stability of the purlin plane and effectively reduces the probability of outward torsional instability and failure of the purlin plane.

[0012] See Figures 1-4 As shown, a wind-resistant ring-type photovoltaic module fixing structure includes purlins 2 supporting the photovoltaic module 1. Long strip pressure blocks are respectively arranged on the four sides of the photovoltaic module 1. Inverted U-shaped bolts 3 are installed on the purlins 2 to press down the long strip pressure blocks. The open ends of the inverted U-shaped bolts 3 pass through angle steel connectors 4 and are locked with nuts 5, so that the angle steel connectors 4 abut against the bottom of the purlins 2. The long strip pressure blocks include long strip side pressure blocks 6 and long strip middle pressure blocks 7, such as... Figure 1 and Figure 2 As shown, the long strip-shaped pressure block 6 is Z-shaped and presses down on one side of the photovoltaic module 1; as Figure 3 and Figure 4 As shown, the long strip of pressure block 7 is U-shaped and has outward pressure strips at both ends of the opening, which are used to press down one side of each of the two adjacent photovoltaic modules 1.

[0013] The two ends of the angle steel connector 4 are connected to the two ends of the long strip edge pressure block 6 or the long strip middle pressure block 7 by the flat steel diagonal tie rod 8, forming a micro-triangular fixing structure, which greatly improves the outward stability of the purlin plane and effectively reduces the probability of outward torsional instability and failure of the purlin plane.

[0014] The length of the U-bolt 3 must be greater than the height of the purlin 2 to ensure that it can be pressed down.

[0015] The bottom of the pressing ends of the long edge pressing block 6 and the long middle pressing block 7 are serrated, which increases the friction.

[0016] When installing the long strip clamps, a specific sequence should be followed, typically starting from one end of the photovoltaic panel and proceeding towards the other to avoid causing unnecessary stress on the panel. Use appropriate tightening force to secure the long strip clamps to the purlins; the force should be sufficient to ensure the stability of the photovoltaic panel, but not excessive to avoid damaging the panel's frame or support structure.
