Technical Field

[0001] This utility model relates to the field of mine ventilation equipment technology, and in particular to an improved adjustable filter window for mine ventilation safety. Background Technology

[0002] The air inlets of ventilation equipment in mines are usually located outdoors. Due to the high level of dust in the outdoors, when air is supplied to the mine, dust is transported into the mine along with it. At the same time, because there is a lot of dust in the mine, the wind will blow the dust around, causing a certain impact on the mine environment.

[0003] The prior art patent application with publication number CN221957617U discloses a ventilation window for mine construction, including a main cylinder with a groove and a filter mechanism installed on it. The main cylinder is connected to a fixed block, and the fixed block is connected to an electric telescopic rod. The telescopic rod is connected to a movable plate, and the movable plate is connected to a filter box. The filter mechanism filters the air entering the mine, preventing the air from carrying a large amount of dust and affecting the working environment of the workers. It also makes it convenient for workers to clean the dust in the filter mechanism.

[0004] However, in the aforementioned existing technologies, the limited window adjustment function makes it difficult to flexibly adjust the ventilation volume according to actual ventilation needs, which is not conducive to use by staff. Utility Model Content

[0005] The purpose of this utility model is to provide an improved adjustable filter window for mine ventilation safety, which aims to solve the problem that the existing window has limited adjustment function and is difficult to flexibly adjust the ventilation volume according to actual ventilation needs, which is not conducive to the use of workers.

[0006] To achieve the above objectives, this utility model provides an improved adjustable filter window for mine ventilation safety, comprising a duct body and an adjusting connection unit.

Multiple fan blades are rotatably connected to the duct body and located on the inner wall of the duct body. Each connecting shaft is fixedly connected to the corresponding fan blade and located above the fan blade. Multiple connecting shafts are rotatably coupled to the main pipe body. Multiple connecting plates are fixedly connected to the corresponding connecting shafts and located above the connecting shafts. Each connecting plate has a strip-shaped hole that slidably engages with the movable frame. The driving component is fixedly connected to the main pipe body and located above the main pipe body. The output end of the driving component is fixedly connected to the movable frame and located on one side of the movable frame. The filter assembly is connected to the main pipe body, and the mounting assembly is connected to the main pipe body.

[0007] The filter assembly includes a base plate, a filter plate, and bolts. The pipe body has a sliding hole that slides with the filter plate.

[0011] This utility model discloses an improved adjustable filter window for mine ventilation safety. In use, the main pipe body is inserted into the mine's air intake pipe and fixed using the mounting assembly. To increase the airflow of the main pipe body, the drive mechanism is activated, causing it to push against the movable frame and move backward within the track plate. During this process, the movable frame, in conjunction with the strip groove, pulls the connecting plate to rotate, causing the fan blades below the connecting shaft to open, increasing the air intake area. To reduce the airflow of the main pipe body, simply move the movable frame in the opposite direction, closing the fan blades and reducing the air intake area. The filter assembly filters impurities in the gas. This design allows workers to flexibly adjust the ventilation volume according to actual ventilation needs, effectively improving ease of use.
