[0002] Underground dust catcher doors are installed at the entrances of tunnels or passages underground in coal mines, which can effectively control the spread of coal dust. Coal dust is a common combustible dust in mines. Its accumulation and spread increase the risk of explosion. By using dust catcher doors, the spread of coal dust can be reduced, which helps to maintain the safety of the underground environment. Underground dust catcher doors are part of the underground explosion-proof safety system of coal mines. By controlling the spread of coal dust, the risk of coal dust explosion and fire is reduced, and the safety of the underground working environment is improved. However, the commonly used dust removal and dust reduction equipment underground is mainly spray-based. For places that cannot be covered by spray, fire sprinkler pipelines are required for artificial dust reduction. In order to ensure the dust removal effect, the spray is often turned on for too long, resulting in serious water accumulation in the tunnel and a lot of coal slime accumulation, resulting in poor on-site hygiene and difficulty in later cleaning.

When the sliding dust-catching door leaf 307 on one side is opened, the sliding dust-catching door leaf 307 on the other side is also opened. The driving device is installed on the dust-catching door frame 2 to drive the steel cable to move. A fine water spray spray frame 302 is installed on the opposite side of the top crossbeam of the two dust-catching door frames 2, and a valve 309 is installed on the fine water spray spray frame 302. The valve 309 is eccentrically connected with a connecting rod 308, and the other end of the connecting rod 308 is hinged to the left side of the top of the sliding dust-catching door leaf 307. The connecting rod 308 is a telescopic rod, and the left side of the top of the sliding dust-catching door leaf 307 is drilled. The bearing is connected to the end of the spray valve 309 through a connecting rod 308. By utilizing the eccentric wheel principle, when the dust-catching door moves horizontally, the connecting rod 308 is driven to move at the same time, and the other end of the connecting rod 308 drives the valve 309 to rotate. The connecting rod 308 is designed as a telescopic rod.

A second pulley 6 is symmetrically installed inside the rod up and down to form a loop structure. At the same time, the steel cable is connected to the sliding dust-catching door leaf 307. When the sliding dust-catching door leaf 307 is opened, the steel cable slides through the second pulley 6, and at the same time drives the cleaning vertical plate 7 to slide on the cleaning plate slide 5 to form a loop interlock, cleaning the dust and dust accumulated on the surface of the sliding dust-catching door leaf 307. At the same time, the cleaning horizontal plate cleans the fixed dust-catching door leaf 306 through the movement of the steel cable, and at the same time ensures the dust-catching effect of the dust-catching door to avoid affecting the dust-catching effect due to untimely cleaning. Drain holes 8 are symmetrically provided in the middle of the bottom end of the cleaning plate slide 5. Due to the design of the nozzle of the fine water spray spray rack 302 facing the dust-catching door, the cleaning plate 6 is discharged through the drainage hole 8 after cleaning, ensuring that the dust-catching door slide 305 remains clean, which helps to avoid excessive dust accumulation, prevent the dust-catching door from failing to work normally due to dust accumulation, and reduce the possibility of deformation of the dust-catching door due to excessive dust.
