Description

A fast, stable and enhanced photovoltaic bracket installation structure

Technical Field

The utility model relates to the technical field of solar panel fixing devices, and in particular to a quick, stable and enhanced photovoltaic bracket installation structure.

Background Art

Photovoltaic brackets are used to fix and support solar panels in photovoltaic modules. Photovoltaic brackets are an important component of photovoltaic power generation systems. According to the classification of the incident angle of the photovoltaic array, photovoltaic brackets include fixed photovoltaic brackets, fixed adjustable photovoltaic brackets and tracking photovoltaic brackets; among them, fixed photovoltaic brackets are usually C-shaped steel frames, which are used in various places such as rooftop distributed photovoltaic power stations, ground centralized photovoltaic power stations, and offshore centralized photovoltaic power stations, especially large-matrix and large-arrangement ground centralized photovoltaic power stations. The installation structure of existing photovoltaic brackets is relatively complex, the installation process is cumbersome, and the structural stability is poor, which brings difficulties to the installation and use of photovoltaic modules.

In the prior art, as shown in FIG1 , when the solar panel 10 is fixed by the C-shaped steel frame, the bolts 20 are passed through the bottom frame hole 101 of the solar panel 10 and the flange hole 302 on the purlin 301 of the C-shaped steel 30 in sequence and then fixed and fastened. As shown in FIG2 , there is also a method of using a middle pressure block 40 to press and fix the solar panel 10, and then the bolts 20 are passed through the bottom hole of the middle pressure block 40 and the flange hole 302 on the purlin 301 of the C-shaped steel 30 and then fixed and fastened.

When installing solar panels on the above-mentioned C-shaped steel frame, the on-site installation accuracy is required to be high, and it is affected by the width of the solar panel. If the hole position does not correspond or the deviation is large, the solar panel cannot be installed; because the installation hole is affected by the width of the solar panel, there are many length specifications of C-shaped steel purlins, which need to be numbered and marked, resulting in more production hours; during installation, it is necessary to distinguish the installation according to the marks and numbers, and distinguishing the marks and numbers takes a lot of time, and it is easy to confuse and delay the on-site installation; the processing hole position of the upper end of the C-shaped steel purlin is affected by the width of the solar panel and is not suitable for all solar panels, and its versatility is poor. In addition, since the flange hole 302 is set on the C-shaped steel 30 purlin 301, the end surface performance decreases when the material of the C-shaped steel 30 purlin 301 is reduced.

Utility Model Content

The utility model aims to solve at least one of the technical problems in the above-mentioned technology to a certain extent. To this end, the purpose of the utility model is to propose a fast, stable and enhanced photovoltaic bracket installation structure to enhance the stability and strength of the fixing parts, with good versatility and applicable to solar panels of different specifications, and convenient installation and high installation efficiency.

A clamping member, wherein the clamping member is provided with an upper limit slot for the upper inserting strip to be clamped in and a lower limit slot for the lower inserting strip to be clamped in, and when the upper inserting strip is clamped in the upper limit slot and the lower inserting strip is clamped in the lower limit slot, the clamping member is restricted in the opening;

A middle pressure block is fixedly connected to the clamping piece.

According to a fast, stable and enhanced photovoltaic bracket installation structure of the embodiment of the utility model, when fixing and supporting the solar panel, the middle pressure block is pressed on the solar panel, and the solar panel is against the upper purlin of the fixing part. Specifically, the upper insert is inserted into the upper limit groove and the lower insert is inserted into the lower limit groove, so that the clamping part is restricted in the opening between the upper insert and the lower insert; then the middle pressure block is fixedly connected with the clamping part, and the middle pressure block is pressed on the solar panel, and the solar panel is against the upper purlin of the fixing part, so that the solar panel is fixed between the middle pressure block and the upper purlin of the fixing part. Therefore, the utility model does not need to set flange holes on the upper purlin of the fixing part, thereby enhancing the stability and strength of the fixing part; at the same time, the upper insert is inserted into the upper limit groove and the lower insert is inserted into the lower limit groove, so that the clamping part can slide, and has good versatility and is suitable for solar panels of different specifications; moreover, it is convenient to install and has high installation efficiency.
