secondly, when the movable bottom plate (25) rises to a corresponding height, a limiting block (43) on the movable bottom plate (25) is abutted to an extension key switch (42), the extension key switch (42) enables the electric telescopic rod (27) to extend downwards to enable the movable bottom plate (25) to slide downwards, and in the process of sliding the movable bottom plate (25), the rubber air bag (23) resets to enable the communicated air suction channel (18) to generate negative pressure, air heated by the operation of electric elements in the cabinet body (1) is sucked into the rubber air bag (23) through the suction hole (19), meanwhile, the humidity sensing switch (28) enables an electromagnet (38) on the inner side of the fixed support column (26) to be electrified to generate magnetism, the electromagnet (38) attracts the iron block (36) to move downwards, and when the iron block (36) moves downwards, the movable push rod (37) pushes a stop block (41) to the outer part of the lower side port of the L-shaped connecting cavity (34), and when the limiting block (43) rises along with the movable bottom plate (25), the stop block (41) completely slides out from the lower side port of the L-shaped connecting cavity (34), so that when the movable bottom plate (25) moves downwards along with the electric telescopic rod (27), the limiting block (43) is abutted against the contraction key switch (40) on the stop block (41) to cause the electric telescopic rod (27) to contract again to cause the movable bottom plate (25) to compress the air in the rubber air bag (23) again, so that the hot air sucked from the cabinet body (1) through the air suction channel (18) is blown to the bottom end face of the movable bottom plate (25) from the air hose (22), the dehumidification effect is improved, and the humidity sensing switch (28) stops sensing until the humidity detected by the humidity sensing switch (28) is lower than a set value, the electromagnet (38) loses the magnetism at the moment, and then the iron block (36) rises and resets under the resilience force of the first spring (35), the stop block (41) is driven to slide back into the L-shaped connecting cavity (34), so that the movable bottom plate (25) can conveniently move down to the initial position, meanwhile, in the process that the movable bottom plate (25) rises each time, the linkage rod (33) is extruded and unfolded to push the impact balls (32) to slide along the concave-convex fluctuated tooth sockets (30), so that the impact balls (32) impact the inner walls of the tooth sockets (30) at intervals, and the movable bottom plate (25) is made of elastic metal materials, so that the movable bottom plate (25) can conveniently vibrate, and water on the lower end face can be shaken off;
thirdly, when the side plate of the cabinet body (1) is electrified due to insulation fault and electric leakage of electrical components in the cabinet body (1), the elastic rubber net (46) is used for preventing external personnel from directly contacting the side plate of the cabinet body (1) to cause electric shock danger, meanwhile, the cabinet body (1) can conveniently radiate heat normally outwards, and when the elastic rubber net (46) is extruded, the insulating plate (48) is pushed, so that the insulating plate (48) drives the connected insulating slide rod (49) to slide towards the inner side of the butt joint groove (51), and the anode and cathode conducting strip group (50) at the tail end is pressed against the inner wall of the butt joint groove (51), so that the signal lamp (47) can emit light as long as the side plate of the cabinet body (1) is electrified, and the contacted anode and cathode conducting strip group (50) can conveniently enable the external personnel to know that the cabinet body (1) is electrified and danger exists;
fourthly, all electrical elements in the cabinet body (1) and wires connected with the outside penetrate through a threading hole (56) on a connecting top plate (4), a rubber sealing plug (55) in the used threading hole (56) is removed in advance, when the wires penetrate through the threading hole (56), a conical rubber sealing sleeve (54) is sleeved on the wires to seal the threading hole (56), therefore, when an electrical element in the cabinet body (1) is in a fire disaster, a smoke induction switch (20) and a flame induction switch (21) generate induction, a winding motor (12) is started to drive a winding column (13) to rotate a winding steel wire (10), the steel wire (10) pulls a square rubber ring (6) downwards to move, the square rubber ring (6) pulls downwards to unfold a corrugated rubber telescopic cover (5), when the square rubber ring (6) is embedded in a square groove (15), corrugated rubber telescopic cover (5) just entangles cabinet body (1), connect roof (4) like this, corrugated rubber telescopic cover (5), flange (25) just enclose cabinet body (1) under a confined space, and smog inductive switch (20) and flame inductive switch (21) make high pressure aspirator pump (3) operation breathe in simultaneously, outwards take out the air in the space of cabinet body (1) place, just so make the interior comburent of cabinet body (1) extinguish under the oxygen condition does not have, avoid dashing on a large scale with the foam and damage other intact components that do not burn.
