The working principle is as follows: when the dust removal device is in use, wind power is generated by electrifying the bidirectional heat dissipation fan 604, in a normal state, the bidirectional heat dissipation fan 604 generates suction from the bottom and blows outside air towards the top of the dc power cabinet 1, and when the bidirectional heat dissipation fan 604 generates suction to suck outside air into the middle of the detachable heat dissipation assembly 6, the outside air firstly passes through the adaptive adjustment air intake assembly 7 and then enters the inside of the first connection frame 602, since the filter frame 606 is wrapped by the water absorbing screen 609, the outside air must pass through the water absorbing screen 609 to be blown towards the top of the dc power cabinet 1 by the bidirectional heat dissipation fan 604, so that the sucked air can be purified and dehumidified by the water absorbing screen 609, thereby avoiding the damage of the internal devices of the dc power cabinet 1 caused by blowing impurities and moist air towards the inside of the dc power cabinet 1, which can be caused by long-time use, more dust can be generated by the water absorbing screen 609, at this time, the detachable plate 607 can be separated from the detachable enclosure 601, and the detachable enclosure 608 can be removed from the first connection frame 602, and the detachable enclosure 602 can be removed from the bottom of the first connection frame 602 by the dust removal frame 602, and the detachable connection frame 602, and the dust removal frame can be removed from the first connection frame 602 by the dust removal frame 602, and the dust removal device, when the first connection frame 21, at this time, the bidirectional heat dissipation fan 604 can be maintained and replaced, when the adaptive adjustment air intake assembly 7 is used, the detachable enclosure 601 and the first connection frame 602 are installed in place, then the second connection frame 707 penetrates through the detachable enclosure 601 and is inserted into the first connection frame 602, so that the inside of the second connection frame 707 is communicated with the inside of the first connection frame 602, at this time, the fixing frames 701 are installed at both ends of the detachable enclosure 601 through bolts, during normal use of the adaptive adjustment air intake assembly 7, the ventilation slots 703 serve as air flow channels, so that the external air can quickly penetrate through the fixing frames 701 and the second connection frame 707 from the outside and enter the inside of the first connection frame 602, and when the external air is moist, the moist air can move on the inner wall of the first installation plate 603 and be continuously absorbed by the first water-swelling strips 704 and the second water-swelling strips 705, so that the first water-swellable strip 704 and the second water-swellable strip 705 absorb water and swell, and the swelling of the first water-swellable strip 704 is restricted by the guiding post 706, so that the swelling range of the first water-swellable strip 704 is defined, and at this time, a structural structure of a tesla valve is formed inside the fixing frame 701, that is, it is difficult for external air to penetrate through the fixing frame 701 through the ventilation slot 703 at the swelling position of the second water-swellable strip 705 and the first water-swellable strip 704, that is, the amount of external humid air entering the first connection frame 602 is reduced, under the influence of the negative pressure of the first connection frame 602, the external air at the dry position is accelerated to be sucked into the inside of the first connection frame 602 through the ventilation slot 703, and when the wind force generated by the bidirectional heat dissipation fan 604 is detected by the wind force detection sensor 605 to be reduced to a target value, the bidirectional heat dissipation fan 604 blows in the reverse direction, and the bidirectional heat dissipation fan 604 makes the high temperature inside the dc power supply cabinet 1 be sucked from the first connection frame 602, the second water-swellable strip 704, second connection box 707 and fixed frame 701 department are outwards discharged, because of the one-way circulation structure of tesla valve, make second water-swelling strip 705 and first water-swelling strip 704 inflation position's ventilation duct 703 can not influence the reverse blowing of air current, then the inside high temperature air current of DC power supply cabinet 1 this moment can be dried second water-swelling strip 705 and first water-swelling strip 704, thereby make adaptive control air inlet subassembly 7 can resume to initial condition, and control two-way cooling fan 604 antiport time for half an hour, because the inside entering humid air of fixed frame 701, this just makes the air of DC power supply cabinet 1 bottom comparatively moist, two-way cooling fan 604 antiport can be dried second water-swelling strip 705 and first water-swelling strip 704 for half an hour, also can blow off the moist air in DC power supply cabinet 1 bottom simultaneously, half an hour after, two-way cooling fan 604 resumes to normal forward blowing, thereby make the device can used repeatedly.
