By setting four fixed bridge rings 4, the staff can be surrounded to ensure the life safety of the staff.

[0024] Please refer to the attached figure in the instruction manual Figure 1 and Figure 2 The outer side of the fence 2 is fixedly connected with a connecting ring 3, and there are four connecting rings 3. The four connecting rings 3 are connected to the outer sides of the four fences 2 respectively, and the inner sides of the four connecting rings 3 are provided with grooves. When using this device, the rope is lowered from the air above the wind turbine, and the rope is fixed through the four fences 2. It can be lifted by a lifting device such as an electric hoist, so that the device can maintain balance during lifting, and the groove is set to make the rope more stable when connected to the fence 2.

[0025] Please refer to the attached figure in the instruction manual Figure 1 and Figure 2 The load-bearing assembly also includes a fixed bridge ring 4, which is fixedly mounted on the top of the load-bearing plate 1 at one end away from the fence 2. The setting of the fixed bridge ring 4 is convenient for connecting the safety rope to prevent accidents caused by accidents, and the staff can hold the fixed bridge ring 4 for leverage.

[0026] Please refer to the attached figure in the instruction manual Figure 1 , Figure 3 and Figure 5 The embrace arm includes a plurality of electromagnetic strips 6, which are symmetrically distributed about the center of the bearing plate 1. A flexible joint ball 5 is arranged between adjacent electromagnetic strips 6, and a soft pad is fixedly connected to the side of the flexible joint ball 5 and the electromagnetic strip 6 facing away from the fence 2. When the device is used, the soft pad is in direct contact with the tower, thereby protecting the outer side of the tower and preventing the flexible joint ball 5 and the electromagnetic strip 6 from scratching the tower. A gap 8 is arranged on the side of the flexible joint ball 5 close to the electromagnetic strip 6. This facilitates the adjustment of the position of the electromagnetic strip 6 and ensures that the electromagnetic strip 6 can be properly rotated through the gap 8 on the flexible joint ball 5.

[0027] Please refer to the attached figure in the instruction manual Figure 1 , Figure 3 and Figure 4 , wherein two electromagnetic strips 6 are connected to both sides of the supporting plate 1 through a flexible joint ball 5, an electromagnet 10 is installed inside the electromagnetic strip 6, a connecting device 9 is arranged inside the flexible joint ball 5, the flexible joint ball 5 is connected to the electromagnet 10 through the connecting device 9, and a current-carrying wire 7 is connected to the bottom of the connecting device 9.
