[0005] The locking structure includes a hand-tightening screw and a clamping block. The hand-tightening screw is threadedly connected to the upper end of the main rod, and the clamping block is fixed on the hand-tightening screw and is located in an L-shaped bayonet.

[0006] The main pole has at least two connecting rings on each side, and the protective net is connected by connecting ropes and D-rings, with the D-rings able to be fastened to the connecting rings.

[0007] The bottom of the L-shaped bayonet uses a V-shaped structure.

[0008] The protective netting is made of nylon.

[0009] Compared with existing technologies, the fall protection device for rooftop photovoltaic power stations has the following advantages:

[0010] This invention features an X-shaped base equipped with four connecting components installed at the bottom of the main pole, which is coordinated with an inclined support rod also equipped with connecting components. In addition, multiple main poles are interconnected by steel wire ropes to form a whole, ensuring the stability of the entire fall arrest device. The steel wire rope is designed for easy disassembly and installation. Attached Figure Description

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figures 1-3 As shown, the fall arrest device for rooftop photovoltaic power stations includes several main poles 1. In practice, the number of main poles 1 can be selected according to the size of the roof. The upper end of the main pole 1 is provided with an L-shaped slot 1a for securing the wire rope 4. The upper end of the main pole 1 also has a locking structure that can lock the wire rope 4. Using this structure, the wire rope 4 is directly placed into the L-shaped slot 1a and locked by the locking structure. The lower end of the main pole 1 is connected to the X-shaped seat 2, the middle part of the main pole 1 is connected to the upper end of the inclined support rod 11, the lower end of the inclined support rod 11 is connected to one end of the fixing plate 10, and the other end of the fixing plate 10 and the end of the X-shaped seat 2 are both provided with connecting components 12 that are connected to the color steel roof. The connecting components 12 are existing products that can be connected to a color steel roof. A protective net 3 is detachably connected between two adjacent main poles 1. Specifically, the protective net 3 is a nylon net. In actual use, the inclined support rod 11 is closer to the edge of the roof than the main pole 1.

[0017] The locking structure includes a hand-tightening screw 9 and a clamping block 8. The hand-tightening screw 9 is threadedly connected to the upper end of the main rod 1, and the clamping block 8 is fixed on the hand-tightening screw 9. The clamping block 8 is located at the L-shaped bayonet 1a. With this structure, by rotating the hand-tightening screw 9, the clamping block 8 can firmly restrict the wire rope 4 at the L-shaped bayonet 1a. Specifically, the bottom of the L-shaped bayonet 1a adopts a V-shaped structure.

[0018] The main pole 1 has at least two connecting rings 5 ​​on each side. The protective net 3 is connected to the connecting rope 7 and the D-type buckle 6, and the D-type buckle 6 can be fastened to the connecting ring 5. With this structure, the protective net 3 can be easily disassembled and assembled.

[0019] This utility model has an X-shaped seat 2 equipped with four connecting components 12 installed at the bottom of the main pole 1, and is coordinated with an inclined support rod 11 with connecting components 12. In addition, multiple main poles 1 are connected to each other by steel wire rope 4 to form a whole, ensuring the stability of the entire fall protection device. The disassembly and assembly structure of the steel wire rope 4 is designed to facilitate quick disassembly and installation.
