And in the impurity suction cleaning process, the second electromagnetic valve 37 and the first electromagnetic valve 28 can be controlled to be synchronously switched between opening and closing, so that the suction force is periodically increased, and efficient cleaning is realized.

Because the square box 6 only covers and shields the single accumulation groove 4, the accumulation grooves 4 at other positions are kept in an open state, and external air can enter the shell 1 from the corresponding accumulation grooves 4, the filtering holes 7, the sliding grooves 5 and the air inlet grooves 11 in sequence, so that the cooling and heat dissipation of the intensive bus duct are not affected.

After the cleaning of the single accumulation groove 4 is completed, the controllable square box 6 corresponds to the next chute 5, and the cleaning of all accumulation grooves 4 is completed.

When the inside sudden spontaneous combustion condition of meeting of casing 1, the emergent start of electro-magnet 14, the magnetism that electro-magnet 14 and second magnet 13 are close to one side each other is homopolar, under the effect of repulsive force, first baffle 8 overcomes the elastic support power of first spring 10 and removes to long-pending groove 4 direction to laminating on spout 5 inner wall, accomplish the cover to filtration pore 7, outside air can't get into the inside of casing 1, air pump 29 pumps casing 1 inside through structures such as first U type box 21, along with the reduction of atmospheric pressure, oxygen content reduces relatively, control the intensity of a fire.

Meanwhile, the telescopic end of the electric push rod 30 stretches out, the square box 6 is driven by the second U-shaped box 22 to be correspondingly attached to the agent box 15, and as the third magnet 19 is in suction fit with the first magnet 12, the second baffle 16 overcomes the elastic supporting force of the second spring 17 and moves towards the square box 6, the bin 34 is expanded and communicated with the shell 1 through the discharge chute 18, fire extinguishing powder in the bin is fed into the shell 1 through the discharge chute 18 and covers the conductive copper bars 31 and other structures, internal fire extinguishing is realized, and the use safety of the intensive bus duct is improved.
