AI Technical Summary
Existing solar photovoltaic power stations are prone to disengage the photovoltaic module and the photovoltaic bracket in the strong wind. This is mainly because the edge block fixing bolt on the edge block on the photovoltaic module is loose under the action of wind, resulting in the edge block and the photovoltaic module. The separation, which then causes the middle pressure block to also be disconnected, triggering a chain reaction, resulting in the photovoltaic module being overturned.
An anti-flip connection is provided between the photovoltaic assembly and the connecting screw. The anti-flip connection includes a screw hole and a hook connection. The hook connection includes a hook and a rewind part. The hook connection is hooked to the component frame of the photovoltaic assembly through the hook connection to ensure that The distance between the connecting screw and the photovoltaic module remains unchanged. Even if the connecting screw and the plastic wing nut are loose, the anti-flip connection can still maintain the solid connection between the photovoltaic module and the photovoltaic bracket.
It effectively avoids the photovoltaic module from the side or medium pressure block in strong winds, prevents the photovoltaic module from being overturned, and improves the stability and safety of the photovoltaic power station.

Abstract
Description
Technical Field
[0001] The utility model relates to solar photovoltaic power station equipment, in particular to an improvement on the installation structure of photovoltaic components in the solar photovoltaic power station equipment. Background Art
[0002] The solar photovoltaic power station is composed of several photovoltaic modules installed on a photovoltaic support. A medium pressure block is arranged between two adjacent photovoltaic modules. The two sides of the medium pressure block are pressed on the module frames of the two adjacent photovoltaic modules. The two photovoltaic modules are fixedly connected to the crossbeam of the photovoltaic support by connecting screws that pass through the medium pressure block and are screwed to the plastic wing nut. The crossbeam of the photovoltaic support is usually a profile with a U-shaped cross section and an inward folded edge at the U-shaped opening. The plastic wing nut is composed of a plastic sleeve product with a wing edge on the upper part and a strip nut block inserted at the lower part. The strip nut block can be inserted from the opening of the U-shaped crossbeam by grasping the wing edge. The insert is then turned to an angle and located below the inward folded edge of the U-shaped opening. The wing edges are placed on both sides of the opening of the U-shaped beam, so that the strip nut block in the plastic wing nut can be placed in the U-shaped beam. After the photovoltaic component is placed in place, it can be screwed together with the strip nut block using connecting screws and fixed to the beam through the middle pressure block. A side pressure block is provided on the outer edge of the outermost photovoltaic component. One side of the side pressure block is pressed on the component frame of the photovoltaic component, and the other side of the support leg is pressed on the beam. The photovoltaic component is also fixed to the beam of the photovoltaic bracket by connecting screws that pass through the side pressure block and are screwed together with the plastic wing nut. Since photovoltaic power stations are installed in the wild or on the roofs of buildings, they are bound to experience strong winds, so photovoltaic power stations are often overturned by strong winds. Most of these incidents are caused by the separation of photovoltaic modules from photovoltaic brackets. One of the main reasons is that the fixing bolts of the side pressure blocks on the edge of the photovoltaic module gradually loosen under the action of wind. Then, when the wind blows the photovoltaic module up and down, the loosened side pressure blocks can easily move away from the photovoltaic module until they are separated from the photovoltaic module, thereby losing their fixing effect on the photovoltaic module. The edge photovoltaic module that has lost the fixation of the side pressure blocks will be lifted up in windy weather and trigger a chain reaction. The middle pressure blocks on the other side will also be separated from the photovoltaic modules, causing the photovoltaic modules on the photovoltaic power station to be overturned one after another. In this way, not only the photovoltaic power station is damaged, but the overturned photovoltaic modules may also cause personal injury accidents or other property losses, and the consequences are very serious.
