before the steel pipe is transported, the corrugated pipe 36 is completely retracted, then a proper amount of prepared bubble liquid is poured from the solution pouring inlet 38, so that the height of the bubble liquid in the siphon generation container 37 is lower than that of the end part of the siphon bent pipe 35, and at this time, no siphon phenomenon is generated, namely, the bubble liquid cannot flow from the siphon generation container 37 to the outside of the siphon generation container 37 along the siphon bent pipe 35, when the tractor 5 drives the transport carriage 6 to run, the corrugated pipe 36 is completely extended, and at this time, the height of the end part of the corrugated pipe 36 is obviously lower than that of the bubble liquid in the siphon generation container 37, so that the siphon phenomenon can be generated, the bubble liquid in the siphon generation container 37 flows onto the rotary fan blades 33 along the bent pipe 35 and the corrugated pipe 36, and then sufficient bubble liquid is gradually adhered to the periphery of the foam generation auxiliary hole 34 on the rotary fan blades 33, and when the transport carriage 6 vibrates and bumps during the transport process, the self-sliding magnetic block 27 can slide in a reciprocating manner in the housing 30 of the adsorption and collection mechanism due to the inertia of the self-sliding magnetic block 27, when the self-sliding magnetic block 27 moves to a position near the first magnetic block 25, the self-sliding magnetic block 27 can be quickly bounced off due to the repulsive force between the self-sliding magnetic block 27 and the first magnetic block 25, when the self-sliding magnetic block 27 moves to a position near the second magnetic block 26, the self-sliding magnetic block 27 can be quickly bounced off due to the repulsive force between the self-sliding magnetic block 27 and the second magnetic block 26, the self-sliding magnetic block 27 can maintain frequent reciprocating movement of the self-sliding magnetic block 27, and dust can be conveniently adsorbed by the electrostatic adsorption soft hair 32 subsequently, so that the self-sliding magnetic block 27 drives the adsorption and collection connecting vertical plate 31 and the rotating fan blade 33 to move in a reciprocating manner through the inner interlocking through groove 29 and the outer interlocking through groove 28, and the electrostatic adsorption soft hair 32 can be adsorbed on the automatic electrostatic adsorption soft hair 32, the excellent dust collecting effect on the transport carriage 6 is realized, the other side of the self-sliding magnetic block 27 drives the rotary fan blade 33 to reciprocate, the rotary fan blade 33 rotates in the moving process, so bubble liquid is fully contacted with air through the foam generation auxiliary hole 34, a large amount of generated foam is uniformly distributed around the transport carriage 6, and part of dust particles which are not collected by the electrostatic adsorption fluff 32 are wet after encountering the foam, therefore, the self mass of the part of dust particles is increased and gradually falls down, and the dust particles can not be scattered into the air in the transport process, the dust collecting effect is realized under the condition without an additional power source, the restraining and settling effect of part of dust is also realized, the dust can not fly, the environment-friendly effect is realized, and therefore, by arranging the magnetic force electrostatic control type adsorption component 2, under the condition without any traditional dust collecting equipment and any additional power source, still realize the excellent dust collecting effect on the transport equipment; aiming at the contradictory characteristics that dust is collected during steel pipe transportation and part of dust is diffused to the outside (air environment during transportation is prevented from being polluted) because the dust cannot be collected, the dust settling mechanism 3 is creatively arranged, and the technical problem that the dust diffusion is inhibited in all directions and is difficult to solve in the prior art is still solved under the condition of not using any traditional dust suppression equipment and any power source.
