A ball groove 1713 is formed in the inner wall of the sliding hole 1704, a lubricating ball 1714 is engaged in the ball groove 1713 in a rolling manner, the lubricating ball 1714 is in point contact with the push-pull rod 1703, and the sliding friction force of the push-pull rod 1703 in the sliding hole 1704 can be weakened by the lubricating ball 1714, so that the push-pull rod 1703 can move smoothly in the sliding hole 1704.

The working principle of the invention is as follows:

through second trachea 9, jar body 3 and first trachea 7 form airflow channel, when needs are to the internal cooling that dispels the heat of switch board 1 cabinet, start air pump 8, the cooling airflow with external through the quick transport of second trachea 9 in jar body 3, get rid of the dust in the cooling airflow under the cooperation of jar internal combination subassembly 14 with high efficiency filter assembly 15, it is internal to enter into switch board 1 cabinet through first trachea 7 again, make cooling airflow can be quick cool down in switch board 1, the distribution module in the guarantee switch board 1 can not receive high temperature to influence and take place ageing, the life of distribution module is improved.

When the cooling air current that flows fast of second trachea 9, under the effect of venturi principle, can let branch pipe 12 suck the hot gas flow in switch board 1, can accelerate the radiating rate in switch board 1, improve the cooling radiating effect to switch board 1, and branch pipe 12 inspiratory hot gas flow can take place the offset with the cooling air current in the second trachea 9, can form the condensate water when cooling air current takes place the heat exchange with the hot gas flow this moment, be favorable to getting rid of the dust in the cooling air current through the condensate water.

When cooling air current flows into jar body 3 in from second trachea 9 fast, because pivot 1403 can be at the internal rotation of commentaries on classics hole 1401 through first bearing 1402, at this moment, utilize the air current effort of air conditioning air current to baffle 1405, can let baffle 1405 drive carousel 1404 and rotate, be favorable to guiding cooling air current downwards, and when cooling air current and baffle 1405 take place to strike, can improve the area of contact of condensate water and dust in the cooling air current, make tiny dust particle can form the large granule dust under the absorption of condensate water, be convenient for follow-up filtration to the dust.

When the cooling air flow passes through the filter screen 1505, large-particle dust can be intercepted by the filter screen 1505, meanwhile, when partial condensed water in the cooling air flow passes through the filter screen 1505, a water film can be formed on the surface of the filter screen 1505 under the action of tension, so that fine dust particles in the cooling air flow can be intercepted, the filtering effect on the cooling air flow is improved, and when the turntable 1404 rotates, the turntable 1404 can drive the transmission shaft 1501 to synchronously rotate, at the moment, the filter screen 1505 can be driven by the fixing ring 1502 and the dust collecting pipe 1504 to rotate, so that the dust particles intercepted by the filter screen 1505 can enter the dust collecting pipe 1504 under the action of centrifugation, the filter screen 1505 is convenient to clean, and the filter screen 1505 can be continuously used.

When the transmission shaft 1501 rotates, the screw thread 1605 on the transmission shaft 1501 is in threaded fit with the screw hole 1604 on the moving block 1603, along with the rotation of the transmission shaft 1501, the moving block 1603 can drive the moving ring 1601 to move upwards, and the moving ring 1601 can drive the linkage ring 1607 to move upwards synchronously through the linkage rod 1606 in the moving process, so that the linkage ring 1607 drives the rubber pad 1608 to cover a dust outlet of the dust tube 1504 when moving upwards, secondary pollution to cooling air flow filtered by the filter screen 1505 can be avoided, when the moving ring 1601 moves upwards, the moving ring 1601 is arranged at the extension spring 1705, and simultaneously, the push-pull rod 1703 can drive the extrusion ring to move upwards synchronously, so that the extrusion ring 1706 compresses the driving air bag 1707 in the moving process, and when air in the driving air bag 1707 is compressed, the air can enter the air expansion rod 1708 through the connecting pipe 1709, so that the air expansion rod 1708 drives the blocking ball 1710 to move downwards under the action of air, and let shutoff ball 1710 block off guide plate 1711's unloading hole 1712, form confined space, the cooling air current that is favorable to passing through after the filtration directly enters into first trachea 7, is convenient for the cooling air current quick entering to switch board 1 in.

When the cooling and heat dissipation operation in the power distribution cabinet 1 is finished, the moving ring 1601 can move downwards under the action of the spring 1705, and at the moment, the linkage ring 1607 moves downwards and enables the rubber pad 1608 to leave from the dust outlet of the dust collecting pipe 1504, so that dust particles collected in the dust collecting pipe 1504 can fall through the dust outlet, when the moving ring 1601 moves downwards, the pressing ring 1706 can drive the driving airbag 1707 to recover downwards, so that the driving air bag 1707 sucks air from the pneumatic telescopic rod 1708 through the connecting tube 1709, make the gas in the pneumatic telescopic link 1708 flow back to in the drive gasbag 1707, the pneumatic telescopic link 1708 can drive the shutoff ball 1710 when contracting and leave from guide plate 1711's unloading hole 1712, open control valve 4 this moment, the dust particle that drops in the laying dust pipe 1504 of being convenient for drops in guide plate 1711 follow unloading hole 1712, the dust particle that the jar body 3 of being convenient for will filter out is discharged.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
