[0025] In this embodiment, Figure 1 and Figure 2 As shown, the bottoms of the first electric facility protection plate 2 and the second electric facility protection plate 12 are fixedly connected with the second telescopic rod 7, the bottoms of the second telescopic rod 7 are fixedly connected with the support frame 8, the materials of the support frame 8 and the second telescopic rod 7 are both stainless steel, the fixing pin 10 is inserted into the second card slot 9 and the third card slot 11, the first electric facility protection plate 2 and the second electric facility protection plate 12 are rotatably connected, the shape of the fixing pin 10 is L-shaped, the material of the first electric facility protection plate 2 and the second electric facility protection plate 12 are both high-temperature resistant insulating material polytetrafluoroethylene, the material of the fixing pin 10 is a metal material titanium alloy coated with an insulating layer, the bottoms of the first electric facility protection plate 2 and the second electric facility protection plate 12 are both movably connected with universal wheels 5, and the material of the first ventilation net 3 and the second ventilation net 20 are both metal materials titanium alloy coated with an insulating layer.

[0026] Among them, through the coordinated use of the second telescopic rod 7, the support frame 8 and the universal wheel 5, the device is easy to move and not easy to tilt. When it is necessary to move the position, the second telescopic rod 7 is retracted and the universal wheel 5 is used to move. The first power facility protection plate 2 and the second power facility protection plate 12 are both made of high-temperature resistant insulating material polytetrafluoroethylene, and the fixing pin 10, the first ventilation net 3 and the second ventilation net 20 are all made of titanium alloy, a metal material coated with an insulating layer, in order to prevent damage to the power facilities due to leakage or fire.
