The shaft tube 6 is rotatably connected to the center position of the fixed ring 1, and the shaft tube 6 can rotate in the fixed ring 1. The left and right ends of the shaft tube 6 are respectively fixed with a high-pressure hose 7 and a nozzle mounting seat 8, wherein the high-pressure hose 7 is used to connect to an external water source. The nozzle mounting seat 8 is welded and fixed with high-pressure nozzles 9 on the upper and lower sides for high-pressure spraying and flushing the inner wall of the pipeline underground in the coal mine. The nozzle mounting seat 8 is fixed with telescopic adjustment mechanisms on the left and right sides, and a cleaning brush 10 for brushing the inner wall of the pipeline underground in the coal mine is connected through the telescopic adjustment mechanism. By installing high-pressure nozzles 9 on the upper and lower sides of the nozzle mounting seat 8, and connecting the cleaning brush 10 on the left and right sides of the nozzle mounting seat 8 through the telescopic adjustment mechanism, the dirt on the inner wall of the pipeline can be cleaned by a combination of high-pressure flushing and brushing.

[0021] The telescopic adjustment mechanism includes a threaded rod 11 and a threaded tube 12, wherein the threaded rod 11 is welded and fixed on the outer wall of the nozzle mounting seat 8, the threaded tube 12 is threadedly sleeved on the outside of the threaded rod 11, and the end of the threaded tube 12 away from the nozzle mounting seat 8 is rotatably connected to the cleaning brush 10 through a bearing. The extension distance of the threaded tube 12 on the threaded rod 11 is adjusted by rotating the threaded tube 12, thereby driving the cleaning brush 10 to adjust its position. A limiting mechanism is connected between the cleaning brush 10 and the nozzle mounting seat 8 to play a limiting role, so that the cleaning brush 10 is more stable during movement.

[0022] The limiting mechanism includes a limiting tube 13 and a limiting rod 14, wherein the limiting tube 13 is symmetrically fixed to the outside of the nozzle mounting seat 8, and the limiting rod 14 is symmetrically fixed to the cleaning brush 10.

At this time, the bristles of the pulley 5 and the cleaning brush 10 just conflict with the inner wall of the pipe, and then the outside The water source is connected to the shaft tube 6 through the high-pressure hose 7, and then injected into the nozzle mounting seat 8 through the shaft tube 6, and then sprayed out by the high-pressure nozzle 9 to perform high-pressure washing of the dirt on the inner wall of the underground pipeline in the coal mine. At the same time, the shaft tube 6 is driven to rotate reciprocally by the reciprocating high-pressure hose 7 to drive the nozzle mounting seat 8 to rotate reciprocally, so that the two groups of high-pressure nozzles 9 can comprehensively wash the inner wall of the underground pipeline in the coal mine. While rotating, the cleaning brush 10 is used to rotate and brush the inner wall of the underground pipeline in the coal mine, so that the dirt can be more fully cleaned. Finally, the inner wall cleaning device of the underground pipeline in the coal mine is pushed and pulled back and forth twice in the underground pipeline in the coal mine to complete the cleaning work.
