[0032] Specifically, sit on the top of the insulating seat 5. Next, by pulling the two insulating safety belts 6 on the right side, the two locking plates 8 are tightly engaged with the corresponding insulating locking shells 7. The completion of this step means that the insulating safety belts 6 have been worn correctly, and can effectively protect the operator from electric shock during operation. After ensuring that the safety belts are worn correctly, the operator can start the extraction fan 10. The operation of the extraction fan 10 allows the negative pressure box 12 to continuously inhale outside air through the extraction pipe 11. At this time, the operator's waist fits tightly against the hole cover plate 13, forming a negative pressure effect, which further improves the fixed protection of the operator. In addition, the operator can also start the hydraulic rod 3 so that the lifting plate 4 drives the insulating seat 5 to rise and fall. This design allows the operator to adjust the height more conveniently when working at high altitudes, thereby improving work efficiency.

[0033] Reference Figure 1 and Figure 2 The outer walls of the two extraction pipes 11 are fixedly installed with rubber pads 14, and the outer walls of the two rubber pads 14 are fixedly connected to the rear side of the negative pressure box 12; the front and rear bottoms of the vertical shell 1 are fixedly connected with two L-shaped plates 17, and the inner walls of the multiple L-shaped plates 17 are fixedly connected with support columns 18; the front side of the insulating seat 5 is provided with two arc grooves, and the outer wall of the insulating seat 5 adopts a smooth design;

[0034] Specifically, the rubber pad 14 can protect the connection at the front side of the extraction tube 11, thereby reducing wear, and the L-shaped plate 17 and the support column 18 make the device more stable when in use.

[0035] Reference Figure 1 , Figure 2 and Figure 4The support mechanism 2 includes two support rods 201, the top walls of the two support rods 201 are fixedly connected to the bottom wall of the lifting plate 4, the rear sides of the two support rods 201 are fixedly connected to the support plate 202, the left and right sides of the inner walls of the two support plates 202 are fixedly connected to the electric telescopic rods 203, the output ends of the two electric telescopic rods 203 are fixedly connected to the fixed plate 204, the rear side of the support plate 202 is fixedly connected to the sliding plate 205, the middle part of the front side of the vertical shell 1 is provided with a slide groove 206, and the rear side of the sliding plate 205 is slidably connected to the slide groove 206;

[0036] Specifically, by adjusting the height of the lifting plate 4, the two support rods 201 and the support plate 202 can be used to stably support the lifting plate 4. This design makes the lifting device more stable and reliable during operation, and provides a safe working environment for the operator. In order to further improve the stability of the lifting plate 4, a sliding plate 205 is also designed in the lifting device. This sliding plate 205 can slide smoothly in the slide groove 206. During the lifting process, the sliding plate 205 can effectively reduce the shaking of the lifting plate 4, making the lifting process more stable. This not only improves work efficiency, but also reduces the risk of accidents caused by the instability of the lifting process. The lifting device is also equipped with two electric telescopic rods 203. By starting the two electric telescopic rods 203, the two fixed plates 204 can be squeezed and fixed to the front side of the inner wall of the opposite shell 1. This design further improves the fixing effect of the position of the lifting plate 4 and ensures the safety of the operator during the lifting process.

[0037] Reference Figure 2 , Figure 3 and Figure 4 The left side of the insulating seat 5 is fixedly connected with a control switch 15, and the control switch 15 is electrically connected to the extraction fan 10, the electric telescopic rod 203 and the hydraulic rod 3 respectively; a protective shell 16 is arranged on the left side of the insulating seat 5, and the front side of the protective shell 16 is rotatably connected to the control switch 15 through a hinge; the outer walls of the multiple insulating safety belts 6 are fixedly connected with tightening shells 9, and the outer shapes of the two tightening shells 9 are arc-shaped;

[0038] Specifically, through the control switch 15 electrically connected to the extraction fan 10, the electric telescopic rod 203 and the hydraulic rod 3 respectively, the control switch 15 can complete the opening and closing of the device, the protective shell 16 can protect the control switch 15 and prevent accidental touch, and the insulating safety belt 6 can be tightened through multiple tightening shells 9.

[0039] Working principle: When wearing the safety belt, the operator sits on the top of the insulating seat 5, and pulls the two right insulating safety belts 6 to engage the two locking plates 8 with the corresponding insulating locking shells 7, thereby completing the wearing of the insulating safety belt 6. By starting the extraction fan 10, the extraction pipe 11 can extract the outside air through the negative pressure box 12, and the operator's waist fits with the hole cover 13 to form a negative pressure effect, thereby improving the fixed protection of the operator. By starting the hydraulic rod 3, the lifting plate 4 drives the insulating seat 5 to rise and fall, thereby facilitating the completion of High-altitude work can ultimately achieve the effect of quickly putting on the safety protection device, which improves the putting-on efficiency, and through the height displacement of the lifting plate 4, the two support rods 201 and the support plate 202 can support the lifting plate 4, and the sliding plate 205 slides in the slide groove 206, so that the lifting plate 4 is more stable during lifting, and by starting the two electric telescopic rods 203, the two fixing plates 204 can be squeezed and fixed to the front side of the inner wall of the shell 1, thereby improving the fixing effect of the position of the lifting plate 4, thereby ensuring the safety of the operator and preventing accidents.
