[0002] With the continuous growth of global demand for clean energy and the continuous development of solar power generation technology, the application prospects of modular assembled photovoltaic brackets will become more and more extensive. It is not only suitable for large-scale ground photovoltaic power stations, but also can be used in residential, commercial buildings and public facilities. Through continuous optimization and improvement of design, modular assembled photovoltaic brackets will make greater contributions to the development of the global clean energy industry; There are many types of existing modular photovoltaic brackets, but they still have certain shortcomings when used. After the traditional photovoltaic panels are set up on the bracket, workers need to pull and support them to prevent the tilted photovoltaic panels from sliding down. At the same time, other workers are arranged to fix the tilted photovoltaic panels with the help of clips; and when two adjacent photovoltaic panels are installed, they need to be measured and aligned, which affects the installation efficiency of batch photovoltaic panels; In order to solve the above problems, reference can be made to the prior art (application number CN202311599152.3, Chinese patent publication number 2024-02-20) disclosed a modular solar photovoltaic panel that is easy to assemble. The photovoltaic panel is installed with a movable and adjustable moving seat at the bottom of the frame. After the moving seat moves to be opposite to the beam of the photovoltaic bracket, the push block is pushed to squeeze the two groups of ear plates against the side walls of the slide rail groove to achieve braking of the moving seat. In this way, the moving seat is fixed under the frame, and when the frame is overlapped on the photovoltaic panel bracket, when the buckle plate is pushed downward and buckled on the beam of the photovoltaic panel bracket, the lifting plate is squeezed and compressed The rubber support frame, and when the lifting plate moves, the traction rope is pulled to tension the elastic connecting plate to produce elastic deformation, and the two groups of elastic connecting plates are closed to clamp the crossbeam of the photovoltaic panel bracket to achieve pre-limitation of the bottom buckle plate when the frame is installed, and the two adjacent frames are assembled through the reserved opening and the positioning plug plate to ensure that the photovoltaic panels installed side by side are neat; At the same time, reference can be made to a modular photovoltaic bracket structure disclosed in the prior art (Chinese patent application number CN202123435771.8, published on August 5, 2022). The photovoltaic bracket structure makes full use of the tensile properties of the rod steel. The rods are mainly unidirectionally tensile and compressed, and the force is simple; And a modular and assembleable photovoltaic bracket device disclosed in the prior art (application number CN202020873640.4, published on November 24, 2020) can be referred to. The photovoltaic bracket can lay the bottom plate on the plane at will by setting the support assembly. The height of the support plate can be adjusted by the cooperation of the slider along the slide rail and the connecting rod to provide a stable support platform, so that the photovoltaic panel can better adapt to any terrain. Connecting screws are respectively provided at both ends of the bottom plate, which can provide stable support force and cooperate with multiple groups of support assemblies to achieve modular assembly of the photovoltaic bracket, which is convenient for assembly and disassembly. Although the above device can solve the existing problems, there are still certain shortcomings when using it.
