[0002] Photovoltaic equipment refers to various types of equipment used to produce, install and maintain photovoltaic power generation systems. It is a key component of solar power generation systems. The rapid development of photovoltaic equipment has not only promoted the continuous decline in the cost of solar power generation, but also provided strong technical support for the realization of global green energy transformation. In recent years, with the advancement of technology, the production efficiency and product quality of photovoltaic equipment have been significantly improved. At the same time, the application of new materials is also constantly expanding the application scope and efficiency of photovoltaic technology.

[0003] The existing photovoltaic equipment that is easy to maintain is installed by installing the photovoltaic module on a bracket for fixed support, placing the photovoltaic module to be used at a suitable position on the bracket, and then screwing the bolts with an external tool to connect and fix the photovoltaic module with the bracket, so that the photovoltaic module can realize the function of photovoltaic power generation in the photovoltaic power generation system. In order to ensure that the photovoltaic module that needs to be installed outdoors can work stably, personnel need to use tools to screw a large number of bolts during fixed installation to ensure the firmness of the installation. Since the use of photovoltaic power generation requires personnel to regularly maintain and repair the photovoltaic equipment, after finding that the photovoltaic module has a fault, personnel need to reverse the bolts with an external tool to remove it, and reinstall it on the bracket after the maintenance is completed. During the installation process, since the photovoltaic module needs to be installed and set at an angle, personnel need to use their hands to make the photovoltaic module stably fit the inclined slope position on the bracket, and then use tools to screw a large number of bolts to stably fix the photovoltaic module and the bracket. This process is time-consuming and labor-intensive, and it is difficult for a single person to complete the installation of the photovoltaic module, which brings a certain degree of trouble to the inspection and maintenance.
