Description

Technical Field

[0001] This utility model relates to the field of coal mine ventilation technology, specifically to a coal mine ventilation device with adjustable airflow direction. Background Technology

[0002] Coal mine ventilation systems are core facilities for ensuring safe production in mines. Through main and auxiliary ventilation fans, they provide fresh air, remove harmful gases, maintain suitable temperature and humidity, and protect the health and safety of workers. Air ducts, air doors, and monitoring systems work together to adjust ventilation in real time to cope with complex environmental changes within the mine, ensuring efficient and safe mining operations.

[0003] Existing ground-mounted coal mine ventilation devices typically consist of an axial flow fan and corresponding support. When the axial flow fan is running, it blows air in a certain direction to achieve ventilation. However, when it is necessary to adjust the airflow direction, the device body usually needs to be moved and rotated. Since the ground in coal mines is usually uneven, it is not easy to place the device on uneven ground when moving and adjusting it. Further fixing of the ventilation device is required, which makes adjusting the airflow direction of the ventilation device inconvenient. Therefore, we propose a coal mine ventilation device with adjustable airflow direction. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example

[0022] Please see Figures 1-4 The diagram shows an adjustable ventilation device for coal mines, including a base plate 100. The base plate 100 can be fixed with ground nails, and the airflow direction can be adjusted using an adjusting vertical plate 130, eliminating the need for re-fixing and moving the device. An axial flow fan 110 and a sliding plate 133 are installed on the top of the base plate 100. The axial flow fan 110 uses a common commercial model, and an air supply duct 120 is installed on the side wall of the axial flow fan 110. The air supply duct 120 uses common rubber. The sliding plate 133 is fixedly connected to the top of the sliding plate 133, which is matched with the air supply duct 120. The side wall of the adjusting vertical plate 130 is provided with an air outlet 132. A common stainless steel dust filter is provided at the air outlet 132. The top of the adjusting vertical plate 130 is fixedly connected to the top of the sliding plate 130 by bolts. The top of the top plate 131 is provided with a locking bolt 124. A gas strut 123 is matched to the outside of the locking bolt 124. The top of the axial flow fan 110 is provided with a fixed shaft 122 that is rotatably matched with the gas strut 123.

[0023] Specifically, the bottom of the sliding plate 133 is provided with a bottom groove 200, and the top of the bottom groove 200 is provided with a sliding opening 201.

[0024] Furthermore, a rotating shaft 210 that fits into the sliding opening 201 passes through the top of the sliding plate 133. When the top of the sliding plate 133 slides, the rotating shaft 210 slides inside the sliding opening 201. A sliding block 220 is rotatably connected to the bottom of the rotating shaft 210.

[0025] Furthermore, the top of the sliding block 220 has a groove 221, and multiple rollers 222 are arranged inside the groove 221. The rollers 222 are made of commonly available hard plastic.

[0026] Furthermore, the top of the sliding plate 133 is provided with a locking knob 230 that matches the top of the bottom groove 200. Rotating the locking knob 230 can lock the sliding plate 133 in conjunction with the bottom groove 200. The sliding plate 133 matches the top of the sliding opening 201.

[0027] It is worth noting that the bottom groove 200 is fixed to the side wall of the base plate 100 by bolts, and the bottom of the base plate 100 is provided with multiple support legs.

[0028] It is worth noting that the support rod 123 is fitted to the top of the air supply duct 120, and an aluminum ring 121 is embedded in the outside of the air supply duct 120.

[0029] In addition, all the electrical components and electrical equipment mentioned above use external power sources. The circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0030] Working principle: By installing an air supply duct 120 and a directional vertical plate 130 that works in conjunction with the air supply duct 120 at the air outlet end of the axial flow fan 110, the directional vertical plate 130 can slide on top of the bottom groove 200 after the locking bolt 124 is loosened, in conjunction with the sliding plate 133. Furthermore, the orientation of the air outlet 132 of the directional vertical plate 130 can be adjusted by the extension and retraction of the gas strut 123. Finally, tightening the locking bolt 124 fixes the direction, thus achieving convenient and rapid adjustment of the air direction of the coal mine ventilation device, eliminating the need for moving the entire device body for air direction adjustment, as is common in coal mine ventilation devices. The inconvenience is reduced, but the convenience of using the coal mine ventilation device is increased. When the vertical adjustment plate 130 is adjusted by sliding and rotating in conjunction with the bottom groove 200, the sliding plate 133 rotates with the rotating shaft 210 of the sliding block 220. At the same time, the sliding block 220 slides inside the bottom groove 200 with the rolling of the roller 222. The sliding of the sliding block 220 inside the bottom groove 200 is used to limit the vertical adjustment plate 130, avoid the problem of the vertical adjustment plate 130 being tilted, improve the stability of the vertical adjustment plate 130 during use, and also contribute to the stable operation of the coal mine ventilation device.
