The projection of the airbag 15 on the box body 11 completely covers the box body 11. Only the part of the airbag 15 located around the substation body 1 is available for inflation. Refer to Figure 1 , Figure 3 The inflating device 2 is used to inflate the airbag 15. When the inflating device 2 fills the airbag 15 with gas, the part of the airbag 15 located around the substation body 1 expands and fits tightly with the bottom of the substation body 1. An exhaust valve 151 is installed on the airbag 15. When the exhaust valve 151 is opened, the gas in the airbag 15 is discharged through the exhaust valve 151.

[0045] Reference Figure 1 , Figure 3 When the water level of a city flood rises, the base 14 can provide a buffer time due to its certain height, so that the inflation device 2 can inflate the airbag 15 in time. The inflated airbag 15 can fit tightly with the bottom of the substation body 1, and can also apply force to the door panel 12 to make the door panel 12 better closed, reducing the probability of water flowing into the accommodating cavity 13 from the gap between the door panel 12 and the box body 11, thereby protecting the substation body 1 and reducing the probability of leakage in the substation during floods.

At this time, the annular block 45 moves to the side away from the annular groove 111 under the action of the third spring 552 until the outer wall of the splash-proof ring 114 abuts against the inner wall of the annular groove 111, and the splash-proof ring 114 does not affect the movement of the annular block 45. When the annular block 45 moves to the bottom of the first flow channel 112, the first rod 5511 moves down to the second limit position and drives the second rod 5512 to move down.
