Description

Technical Field

[0001] The utility model relates to the technical field of coal mine ventilation, in particular to a coal mine ventilation regulating device. Background Art

[0002] In the prior art, after searching, it was found that, for example, a Chinese patent (grant number: CN220451932U) discloses a ventilation and adjustment device for a coal mine. The advantage brought by the above patent is that the blower mechanism arranged in the cylindrical shell is used to suck the outside air into the cylindrical shell and then discharge it from the other end. The movable mechanism arranged enhances the mobility of the device. The height adjustment mechanism arranged is used to adjust the height of the cylindrical shell, which is convenient for arbitrary adjustment of the height of the cylindrical shell. In the process of adjustment, the air flow at different heights in the mine can be enhanced. The wind direction adjustment mechanism arranged can adjust the wind direction at the air outlet position of the cylinder. The two filter plates arranged in the filter mechanism can filter the air introduced into the cylindrical shell by the blower mechanism, reduce the amount of dust in the coal mine, and cause the air output of the device to decrease. The clean water in the water tank can be regularly pumped to the surface of the filter plate through the two nozzles by the water pump arranged, so as to realize the cleaning of the filter plate. The dirty water flowing along the filter plate to the conical pool can be led out of the conical pool by removing the waterproof plug.

[0003] However, the above patent can only adjust the wind direction but not the air volume when in use, so improvement is needed. Utility Model Content

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A coal mine ventilation and adjustment device comprises an air expansion cylinder fixed on a cylindrical shell, wherein the air expansion cylinder and an air blowing mechanism in the cylindrical shell are respectively located at two ends of the cylindrical shell;

[0007] The air expansion cylinder is provided with a plurality of external air outlets arranged at equal intervals up and down, away from the surface of the cylinder shell, and an adjustment mechanism is arranged inside the air expansion cylinder.

[0008] Specifically in the utility model, the adjustment mechanism includes an adjustment shell rotatably mounted in the cylindrical shell, and the adjustment shell matches the inner wall of the cylindrical shell;

[0009] The regulating shell is provided with a plurality of air inlet long through slots arranged at equal intervals up and down near the surface of the cylindrical shell, the air inlet long through slots are connected to the cylindrical shell, and the regulating shell is provided with an air outlet away from the surface of the cylindrical shell.

[0010] In order to facilitate the movement of the adjustment shell, the external air outlet is composed of two short air outlet slots, and the opposite ends of the short air outlet slots are not in contact. A lever is provided on the upper and lower sides of the air outlet, and the lever is fixed on the surface of the adjustment shell, and the lever is located between the two short air outlet slots.

[0011] In order to lock the adjusting shell, a bolt is vertically screwed on the highest point of the air diffusion cylinder, and the lower end of the bolt is pressed against the highest point of the adjusting shell.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the adjusting shell can be rotated and locked in the air expansion cylinder, the air volume can be adjusted by adjusting the overlapping area between the air outlet on the shell and the short air outlet slot, and the air outlet direction can also be adjusted. The structure is simple and the practicality is higher. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] like Figure 1 As shown, the utility model provides a coal mine ventilation adjustment device, including an air expansion cylinder 1 fixed on a cylindrical shell M, the air expansion cylinder 1 and a blower mechanism N in the cylindrical shell M are respectively located at two ends of the cylindrical shell M, the blower mechanism N is a prior art, and a more specific working principle is not repeated in the utility model;

[0022] The air expansion cylinder 1 is provided with a plurality of external air outlets arranged at equal intervals up and down on the surface away from the cylinder shell M, and an adjustment mechanism is provided inside the air expansion cylinder 1.

[0023] like Figure 1-4 As shown, in the present utility model, the adjustment mechanism includes an adjustment housing 2 rotatably mounted in the cylindrical housing M, and the adjustment housing 2 matches the inner wall of the cylindrical housing M;

[0024] The regulating shell 2 is provided with a plurality of air inlet long through grooves 2-1 arranged at equal intervals up and down near the surface of the cylindrical shell M, the air inlet long through grooves 2-1 are connected to the cylindrical shell M, and the regulating shell 2 is provided with an air outlet 2-2 away from the surface of the cylindrical shell M.

[0025] like Figure 5 As shown, in order to facilitate the movement of the adjustment shell 2, the external air outlet is composed of two short air outlet slots 1-1, and the opposite ends of the short air outlet slots 1-1 are not in contact. A lever 3 is provided on the upper and lower sides of the air outlet 2-2. The lever 3 is fixed on the surface of the adjustment shell 2, and the lever 3 is located between the two short air outlet slots 1-1.

[0026] like Figure 1 As shown, in order to achieve locking of the regulating shell 2 , a bolt 4 is vertically screwed into the highest point of the air diffusion cylinder 1 , and the lower end of the bolt 4 is pressed against the highest point of the regulating shell 2 .

[0027] like Figure 6 As shown, the specific working principle of the utility model is described in detail below: after the bolt 4 is unscrewed from the air expansion cylinder 1, the lever 3 can be toggled, and the lever 3 can be moved up and down to drive the adjusting shell 2 to rotate up and down. At this time, the lever 3 will rotate in the air outlet short through slot 1-1. When the lever 3 drives the adjusting shell 2 to rotate to a suitable angle, the bolt 4 is screwed on the air expansion cylinder 1 until the lower end of the bolt 4 is tightly against the highest point of the adjusting shell 2, thereby locking the adjusting shell 2. The wind generated by the hair dryer structure N is blown out through the air inlet long through slot 2-1, the adjusting shell 2, the air outlet 2-2, and the air outlet short through slot 1-1.
