Because the external tooth 14 and the screw rod 9 of every 12 one sides of shower pipe fittings cooperate for screw rod 9 can drive shower pipe fittings 12 to remove to solid fixed ring 8 when removing in solid fixed ring 8 in the orientation, and get into solid fixed ring 8 inside its one side of shower pipe fittings 12 under solid fixed ring 8's butt effect, make shower pipe fittings 12 more paste tightly mutually with screw rod 9, make the screw rod 9 can be just drive shower pipe fittings 12 to solid fixed ring 8 internal motion. Thereby retracting the shower pipe 12 and the screw 9 completely into the fixing ring 8.
Specifically, the following are mentioned: through the matching of the two limiting rods 31 symmetrically arranged along the axis and the limiting holes 30, the circular plate 19 cannot rotate relative to the fixing ring 8, and further the servo motor 18 arranged on the circular plate 19 cannot rotate, so that the output end of the servo motor 18 can guide the screw rod 9 to rotate, and the stable operation capability of the system is improved. Meanwhile, the circular plate 19 can cover the inner circumferential surface of the fixing ring 8 when the spraying device is not used by additionally arranging the circular plate, so that external dirt is prevented from entering the fixing ring 8.
Furthermore, one end of each of the four arc-shaped plates 10 in the cabinet body 1 is fixedly connected with the same fixing plate 20, four branch water pipes 21 respectively communicated with the four spraying pipe fittings 12 penetrate through the fixing plate 20, one end of each of the four branch water pipes 21 is connected with the same main water pipe 22, an electromagnetic water valve 23 is arranged on the main water pipe 22, and the electromagnetic water valve 23 is connected with the controller 6 through a wire.

Further, the inner wall of the cabinet 1 is slidably connected with a cover plate 25 for covering the heat dissipation hole 24, one end of the cover plate 25 is provided with a driving cylinder 26, and the driving cylinder 26 is electrically connected with the controller 6.
In practical use, the electric components inside the cabinet 1 generate heat, and the heat dissipation hole 24 can accelerate the interaction between the heat inside the cabinet 1 and the outside. However, when a fire disaster occurs outside, when the spraying device is adopted to spray the outer vertical surface of the cabinet body 1, the moisture of the water enters the cabinet body 1 through the heat dissipation holes 24 and then causes hazards such as electrical short circuit. Or, when the fire breaks out in inside, this application adopts the mode of evacuation to take out cabinet body 1 is inside to the greatest extent, and its louvre 24 all can be with leading-in of outside air for it is useless to take out the vacuum.
Therefore, the heat dissipation holes 24 need to be sealed off in case of fire both inside and outside the switchgear. This application passes through the cylinder drive for when taking place conflagration, cylinder drive apron 25 removes in order to block up louvre 24.
