[0018] Preferably, the driving assembly comprises a motor mounted on the front side of the cylinder, and the driving end of the motor is fixedly connected to the front side of the rotating rod.

[0019] Working principle: When installing pipelines in mines, first install and fix the mounting base for installing pipelines on the surface of the mine wall according to the laying route of the pipelines, then install the ventilation duct on the mounting base, bite the bite washer on the pipe body on the bite washer on the mounting base, and insert the connector 1 on the bite washer into the connector 2, and keep the dust retaining net on the pipe body facing the installer in front. During this period, if the distance between two adjacent mounting bases is slightly larger or the angle is wrong or not parallel, the ventilation pipe can be pulled to make the part of the telescopic bellows offset or stretch accordingly to adapt to the distance between the two mounting bases. After the ventilation pipe is properly installed, the locking piece in the connector 2 is marked. The water hose is then installed by aligning the stopper on the water hose with the L-shaped groove on the screw seat and twisting the water hose so that the stopper connected thereto is stuck in the L-shaped groove. The screw sleeve is then moved along the water hose to the screw seat and rotated to tighten so that the screw seat closes along the L-shaped groove, and the stopper is clamped to prevent it from falling out of the L-shaped groove while closing the opening of the L-shaped groove to further prevent the water hose connected to the stopper from detaching from the spray head. Then, the connecting pipe 2 connected to the delivery pump body is installed on the spray head at the rear end in the manner of a water hose connection, and the connecting pipe 1 connected to the barrel is installed on the mounting seat in the manner of a ventilation pipe connection.

[0020] During the ventilation process of the mine, the rotating rod driven by the motor synchronously drives the exhaust fan and the missing gear. The exhaust fan rotates to guide the external air flow through the dust baffle plate, enters the cylinder, and enters the connected ventilation pipe along the connecting pipe 1. After the air enters the ventilation pipe, the air pressure pushes open the thin ventilation curtain and is discharged into the mine along the dust baffle net. The missing gear meshes with the gear 1 on the top side, so that the gear 1 drives the winding roller to rotate. The rotating winding roller reels the traction rope, and the traction rope pulls the connected cleaning brush to rise along the slide rail. During the rising process, one side of the cleaning brush brushes the dust baffle plate to clean the dust accumulated in the surface holes blocked by the exhaust. The two gears 2 on the left side of the gear meshing make the turbine rotate, stirring and pressurizing the clean water injected into the shell from the water inlet, and transporting it along the connecting pipe 2 to the connected water hose and spray head, and making the pressurized clean water spray out in the form of water mist along the small water outlet of the spray head. When the part of the missing teeth on the missing gear rotates to gear 1 or gear 2, the meshing will be temporarily stopped, and the winding roller that was rotating before will shrink the clockwork spring, and at this time it will be driven by the reset of the clockwork spring to rotate, and under the action of the cleaning brush's own gravity, it will slide down and reset along the slide rail, and the turbine will stop rotating, and the delivery of clean water will be suspended until the missing gear is re-engaged, and the above work will be performed reciprocatingly.

[0021] The present invention provides a mine ventilation device that is convenient for arranging pipelines. It has the following beneficial effects:

[0022] 1. In the present invention, the modular split design of the pipeline part can make the laying of the pipeline more flexible, reduce the problem of too short or too long structure, and thus eliminate the need for splicing or truncation, thereby ensuring the integrity of the pipeline and improving its reusability. If damage occurs somewhere in the pipeline part, only the corresponding part needs to be replaced and maintained, eliminating the impact on other pipelines and reducing the cost of pipeline replacement and maintenance.

[0023] 2. In the present invention, the split design also provides more convenient transportation. The one-piece molded pipe needs to consider its own toughness after rolling, which causes it to be difficult to bend and roll, so it occupies a large space. The pipe can be transported in a regular manner through a container body, which greatly improves the convenience of transportation.

[0024] 3. The present invention utilizes a single driving source to simultaneously realize the purpose of delivering fresh air, cleaning the air inlet, and spraying water mist inside the mine to reduce dust, thereby providing a more comfortable working environment for workers in the mine, reducing the impact of dust on the health of mine workers, and preventing the accumulation of a large amount of dust at the air inlet, thereby ensuring the normal operation of the equipment and avoiding the reduction of air intake efficiency.
