Description

Technical Field

[0001] The utility model relates to the field of photovoltaic component installation technology components, in particular to a special tool for fastening and disassembling photovoltaic components. Background Art

[0002] Photovoltaic modules are important components in photovoltaic power generation projects. In photovoltaic projects, the installation and construction time of photovoltaic modules accounts for more than 50% of the total construction period. When installing, photovoltaic modules are placed on at least two bracket purlins. There is a gap between two adjacent photovoltaic modules. A pressure block is arranged in the gap. The pressure block is often U-shaped and is fixedly connected to the bracket purlin by mounting bolts and mounting nuts. As the photovoltaic module equipment is put into operation for a longer time, the pressure block screws between the photovoltaic modules will gradually loosen due to the influence of severe weather such as strong winds, causing the photovoltaic modules to fall off. When restoring the fallen photovoltaic modules, because the photovoltaic modules have a certain height and the front of the modules is not easy to step on, the use of tools such as ladders can easily damage the photovoltaic modules. It is also very difficult for people to tighten screws in the limited operating space of the ladder. Therefore, it is necessary to use proprietary tools to carry out installation and disassembly work.

[0003] In the prior art, the improvement of the installation tools of photovoltaic modules is mostly reflected in the installation method. For example, the Chinese patent document with the publication number CN216967602U discloses a special tool for tightening the pressing block for installing photovoltaic modules, including an operating rod for passing through the gap between two adjacent photovoltaic modules from bottom to top, the operating rod includes an extension rod for being arranged above the photovoltaic module and extending toward the pressing block between the two photovoltaic modules, and the end of the extension rod is provided with a wrench extending downward, and the wrench is provided with a rotation-stopping structure for cooperating with the bolt head of the installation bolt passing through the pressing block; the operating rod is provided with a holding structure for holding by hand to keep the operating rod relatively fixed, and the holding structure is used to be arranged below the photovoltaic module. The special tool of the utility model has a simple structure, is easy to carry, and has a low manufacturing cost. It can realize the installation operation of the pressing block by a single person below the photovoltaic module, improve the efficiency of installation and tightening work, reduce the investment of construction personnel, and has significant economic benefits. At the same time, it eliminates the problem that the operator presses the edge position of the photovoltaic module and causes the risk of crushing the photovoltaic module.

[0004] Although the above device has certain advantages in improving the photovoltaic module installation tools, it still has some shortcomings:

[0005] The above-mentioned device cannot fasten and disassemble photovoltaic modules of a certain height, and still needs to be installed with the help of external force. The photovoltaic modules are easily damaged during operation, which increases the operation time and has certain safety risks. Utility Model Content
