The working principle of the invention is as follows: when the internal temperature of the switch cabinet is increased, the heat conducting rod 31 can transmit the temperature to the connecting cylinder 32, so that the internal temperature of the connecting cylinder 32 is increased, after the internal temperature of the connecting cylinder 32 is increased, the gas in the connecting cylinder 32 is expanded, the movable block 37 is pushed to move downwards and drive the elastic telescopic rod 38 to shrink, when the movable block 37 moves in the limiting ring 33 to be in contact with the sliding block 36, the movable block 37 is influenced by the elastic force of the spring I35, the movable block 37 is clamped at the upper end of the sliding block 36, the pressure on the movable block 37 is gradually increased along with the continuous expansion of the gas, so that the movable block 37 pushes the sliding block 36 to compress the spring I35 until the sliding block 36 enters the sliding groove I34, the movable block 37 is not limited by the sliding block 36 and moves downwards, the movable block 37 is separated from the limiting ring 33, and then the air expanded in the connecting cylinder 32 is sprayed into a gap between the outer shell 1 and the inner shell 2 from a hole in the center of the limiting ring 33, and drives the air in the gap between the outer shell 1 and the inner shell 2 to flow, after the air in the connecting cylinder 32 flows out, the pressure on the upper end of the movable block 37 is reduced, the movable block 37 is pushed to move upwards under the action of the elastic force of the elastic telescopic rod 38, when the movable block 37 contacts with the sliding block 36, because the movable block 37 is positioned at the lower end of the sliding block 36, compared with the condition that the length of the elastic telescopic rod 38 is shorter and the elasticity is larger than the elastic force of the spring I35 when the movable block is contacted with the upper end surface of the sliding block 36, the movable block 37 pushes the sliding block 36 to slide into the sliding groove I34, so that the movable block 37 moves back to the original position, and because most of the air in the connecting cylinder 32 is discharged, the internal pressure is reduced, the movable block 37 is pushed to move to the inside of the connecting cylinder 32 under the action of the external air pressure and stretches the elastic telescopic rod 38, so that the external air flows into the connecting cylinder 32, after the air pressure is balanced, the movable block 37 moves to the original position, and the operation is repeated after the temperature rise rises and the air expands, so that the control device 3 intermittently sprays the air into the gaps of the outer shell 1 and the inner shell 2 under the unpowered condition, and the air is further driven to flow;
the gas ejected from the connecting cylinder 32 pushes the gas in the gaps of the outer shell 1 and the inner shell 2 to flow downwards, and is discharged through the communication hole I112, the communication hole II 28 and the perforation III 7 positioned below, so that the air pressure in the gaps of the outer shell 1 and the inner shell 2 is reduced, and then the outside air enters the gaps of the outer shell 1 and the inner shell 2 through the perforation III 7 positioned above, so that the proper temperature is ensured in the gaps of the outer shell 1 and the inner shell 2;
when the internal temperature of the inner shell 2 rises, the gas in the inner shell 2 expands to drive the air bags 27 to expand, the L-shaped sliding plates 110 on the two sides of the air bags 27 abut against the side surfaces of the air bags 27, so that when the air bags 27 expand, the L-shaped sliding plates 110 are pushed to move, after the L-shaped sliding plates 110 close to the inlet 22 slide for a certain distance, the communication holes I112 on the L-shaped sliding plates 110 are in contact with the baffle rods 18, the baffle rods 18 seal the communication holes I112, the communication holes III 113 are communicated with the corresponding inlet 22 and outlet 29, so that the space between the inner shell 2 and the outer shell 1, the inner shell 2 is communicated, after the gas is sprayed out of the connecting cylinder 32, the gas enters the inner shell 2 through the communication holes III, drives the gas in the inner shell 2 to flow, then is discharged from the outlet 29, and drives the gas in the inner shell 2 to flow, and when the sprayed gas enters the inner shell 2 through the inlet 22, the baffle plates 23 are limited, only can flow upwards, part of the gas flows through the ventilation openings 24 with different heights after passing through the inclined baffle plates 25, and the gas sprayed into the inner shell 2 can drive the gas in the inner shell 2 to flow, so that only partial gas flow is prevented from affecting the heat dissipation effect; after the temperature is reduced, the air bag 27 contracts, and the two L-shaped sliding plates 110 are driven to move to the original positions under the action of the spring II 15;
the sprayed gas enters the inner shell 2 through the dust screen 111, and when the L-shaped sliding plate 110 moves back and forth under the action of the air bag 27 and the spring II 15, the sprayed gas contacts the scraping plate 19 to scrape dust on the dust screen 111, so that blockage is avoided.
