[0002] Photovoltaic cell modules (also called solar panels, photovoltaic modules) are the core part of a solar power generation system and also the most important part. Their function is to convert solar energy into electrical energy, which can be sent to a storage battery for storage or used to drive a load. The quality and cost of photovoltaic cell modules will directly determine the quality and cost of the entire system. Component products with high power, high efficiency, high reliability, and high power generation are the key to promoting the full - parity era of photovoltaic power generation. In addition, the installation quality of photovoltaic modules will also directly affect the safety performance of solar power stations. If the installation work is not in place, it may lead to unstable assembly and other situations, which may cause various safety hazards, such as fires. Therefore, high - quality installation work of photovoltaic modules is one of the keys to ensuring the safety of solar power generation.

[0003] However, there are some problems in the existing technology: Before installing the module, the placement method of the module is also crucial. If the module is placed unstably or in the wrong position, it may cause damage to the module or hidden cracks in the module, posing a great potential safety risk during the later power generation process. Therefore, we propose an anti - toppling device for solar photovoltaic modules. Summary of the Utility Model

[0024] As Figure 2As shown in the figure, at both ends of the chassis 11, there are respectively movably connected a support frame 12 with a telescopic structure and a fixed frame 13 for receiving and limiting the support frame 12. On the upper end surface of the chassis 11, there is a receiving groove 113 for receiving the support frame 12. After rotating the fixed frame 13 to the vertical state, the receiving groove 113 and the support frame 12 are exposed; at this time, the support frame 12 can be rotated to the vertical state, and the fixed frame 13 can be reset to the horizontal state to limit the support frame 12 in the vertical state; thus, the folding of the anti-falling device body 1 is realized, which is convenient for transportation and movement.

[0025] As Figure 3 shown in the figure, at the rear end of the chassis 11, there is integrally formed a limiting member 112 with a concave cross-section, and on the outer walls of both sides at the front end of the chassis 11, there are fixedly connected hinge members 111 with a concave cross-section; the limiting member 112 and the hinge member 111 are used to connect the support frame 12 and the fixed frame 13, improve the mobility among the three, and fold and receive the anti-falling device body 1 as needed, which is convenient for transportation and movement.
