Description

Technical Field

[0001] This utility model belongs to the field of mine ventilation technology, and in particular relates to a ventilation regulation device for underground coal mines. Background Technology

[0002] The underground working environment in coal mines is complex, and ventilation directly affects safe production. Traditional ventilation control devices have many shortcomings, such as poor adjustment accuracy, making it difficult to accurately adjust the air volume according to the real-time needs of different working areas, resulting in poor ventilation in some areas and an increased risk of gas accumulation; slow response speed, unable to quickly adjust ventilation parameters in the face of changes in roadway layout and mining progress; and poor equipment stability, easily damaged in the harsh underground environment, requiring frequent maintenance and affecting the continuous and stable operation of the ventilation system. These problems seriously restrict the efficiency and quality of safe production in coal mines, and there is an urgent need to develop new ventilation control devices to improve the current situation.

[0003] However, existing underground ventilation control devices in coal mines are not convenient for changing the ventilation direction during use. This makes it difficult to flexibly control the airflow direction when dealing with complex and ever-changing underground roadway environments and emergencies, thus making it difficult to ensure good ventilation underground and seriously affecting mine safety production and operational efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a ventilation regulation device for underground coal mines. By setting up a regulation mechanism, it solves the problem that existing underground coal mine ventilation regulation devices are not convenient to change the ventilation direction during use. This makes it difficult to flexibly control the airflow direction when dealing with complex and ever-changing underground roadway environments and emergencies, thus making it difficult to ensure good ventilation underground and seriously affecting the safety of mine production and operational efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a ventilation and regulation device for underground coal mines, including a housing, on which an adjustment mechanism and a cleaning mechanism are provided;

[0007] The adjustment mechanism includes a slide groove 1 formed on the box body, the slide groove 1 penetrating the box body, a plurality of slide grooves 2 formed on the left inner wall of the slide groove 1, a slider 1 slidably connected to the inner wall of each of the slide grooves 2, a spring telescopic rod 1 fixedly connected to the left inner wall of each of the slide grooves 2, and a plurality of slider 1 fixedly connected to the right side of each of the spring telescopic rods 1, a slider 2 slidably connected to the inner wall of the slide groove 1, a plurality of grooves formed on the left side of each slider 2, and each of the slider 1s being adapted to the plurality of grooves. The cleaning mechanism includes a limiting block fixedly connected to the inner wall of the box body.

[0008] Furthermore, two sliding grooves 3 are provided inside the box. The left side of each of the two sliding grooves 3 is connected to the sliding groove 1. A slider 3 is slidably connected to the inner wall of each of the two sliding grooves 3. The left side of each of the two sliders 3 is fixedly connected to the slider 2.

[0009] Furthermore, the inner wall of the slider two is fixedly connected with several racks, the rear inner wall of the box is rotatably connected with several shafts, the front sides of several shafts extend into the slide groove one, the outer walls of several shafts are fixedly connected with wind baffles, the outer walls of several shafts are fixedly connected with gears, and the several gears mesh with several racks respectively.

[0010] Furthermore, a filter plate is slidably connected to the inner wall of the housing, and several spring telescopic rods are fixedly connected to the left side of the filter plate. The left side of each of the spring telescopic rods is fixedly connected to a limiting block. A handle is provided on the right side of the filter plate, and a striking block is fixedly connected to the left side of the handle. The left side of the striking block is in contact with the filter plate.

[0011] Furthermore, the outer wall of the handle and the inner wall of the housing are both hinged with a number of hinge blocks. The hinge blocks located inside the housing are fixedly connected to the side of the handle with a spring telescopic rod three. The side of the spring telescopic rod three near the handle is fixedly connected to the hinge blocks located on the handle.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By setting an adjustment mechanism, when it is necessary to adjust the air direction, the second slider can be pulled, so that it slides in the first slide under the interaction of the third slide and the third slider. When the second slider slides, the first slider will slide into the second slide under the pressure of the groove, and the first spring extension rod will be compressed to generate elastic force. When the second slider slides, the wind baffle will be rotated through the shaft under the interaction of the rack and gear, thereby adjusting to the corresponding position and adjusting the air direction to the appropriate position. This allows the air direction of the ventilation device to be changed, ensuring that the device can flexibly control the airflow direction when dealing with the complex and ever-changing underground roadway environment and emergencies, thereby ensuring good ventilation underground and avoiding affecting the mine's safe production and operational efficiency.

[0014] 2. By setting up a cleaning mechanism, a large amount of dust and other impurities will be present in the operating environment of the device. The filter plate will prevent these impurities from entering the device and will adhere to the filter plate. When it is necessary to clean the filter plate, the handle can be pulled, which will cause the spring telescopic rod three to stretch under the action of several hinge blocks, generating elastic force. When the handle is released, the spring telescopic rod three will cause the striking block to strike the filter plate, making it slide in the box and compress the spring telescopic rod two, thereby achieving vibration cleaning. This will clean the filter structure in the device and prevent dust and other impurities from adhering to the filter structure and clogging it, thus affecting the ventilation effect and further ensuring good ventilation underground.
