Description

Technical Field

[0001] The utility model relates to the technical field of bridge frames, in particular to a splicing bridge frame for a photovoltaic inverter with interface protection. Background Art

[0002] A bridge is a support structure used for wiring cables, pipes, etc. In a photovoltaic power generation system, a photovoltaic inverter is required to convert the variable direct current generated by the solar panels into alternating current at the mains frequency. The end of the photovoltaic inverter will be connected to the cable, which will be laid inside the bridge. By laying the cable inside the bridge, the cable can be protected. However, the existing spliced ​​bridges still have some problems during actual use. For example, the installation bottleneck in complex environments: outdoor work often needs to be carried out in a small space or at high altitudes. Traditional bridge frames mostly use bolt flange docking. During installation, multiple stations need to coordinate to align the hole positions, and they rely on tools such as wrenches to repeatedly tighten, which makes single-person operation difficult, especially in complex scenarios such as sloping roofs. The installation time is increased; structural failure under dynamic stress: existing plug-in connectors mostly use flat overlap, which is prone to micro-displacement under alternating loads such as temperature difference deformation (-30℃~70℃ working conditions) and fan vibration; inherent defects in protective performance: traditional interface sealing uses rubber pad compression, which is prone to gasket aging and cracking after long-term exposure; compatibility barriers to modular expansion: the specifications of bridge frames on the market are confusing, and the size tolerance of dovetail grooves from different manufacturers is as high as ±1.5mm, forcing the engineering party to customize adapter components.

[0003] While the industry has attempted to address these pain points, issues such as excessive structural complexity and difficulty balancing waterproof sealing with rapid assembly and disassembly persist. Enabling blind-plug quick docking of bridges while maintaining an IP65 rating, while also meeting engineering requirements for vibration resistance and scalability, has become a pressing technical bottleneck in the photovoltaic system integration field.

A card groove 312 is provided on both sides of the left and right sides of the sealing block 31, and the card groove 312 slides with the card block 145. When one end of the bridge body 1 needs to be protected, the sealing block 31 on one side of the protective plate 3 can be extended to the inside of the sealing groove 11 at one end of the bridge body 1, and the fixing bolt 121 can be rotated. The fixing bolt 121 is rotated to fix the fixing bolt 121 with the thread groove 311 on the second sealing block 31, so that one end of the bridge body 1 can be protected. When the other end of the bridge body 1 needs to be protected When protecting, the knob 2 142 on the installation box 3 141 can be rotated, and the knob 2 142 drives the screw 2 143 to rotate, thereby moving the sealing block 111. When the sealing block 111 moves to the deep end of the connecting groove 14, the pressure on a group of blocks 145 can be released, and then under the action of the spring rod 144, the block 145 pops out. At this time, the sealing block 2 31 on one side of the protective plate 3 can be aligned with the connecting groove 14 and put in.
