Wind direction adjusting device of underground local ventilator of coal mine

Abstract

The invention discloses a wind direction adjusting device of an underground local ventilator of a coal mine. The wind direction adjusting device comprises a base, a box is connected to an upper side of the base through a plurality of telescopic rods, the upper side of the base is connected with a lower side of the box through a lifting mechanism, ventilating windows are arranged on two sides of the box, the ventilating windows are provided with a plurality of wind-out blades in horizontal equidistant arrangement, and two sides of the wind-out blades are rotationally connected with inner wallsof the ventilating windows through rotating shafts. The wind direction adjusting device of the underground local ventilator of the coal mine has the advantages that the height of the box can be adjusted through the lifting mechanism, so that requirements on ventilation of wind outlets of different coal mines can be satisfied; through an arranged driving mechanism, the wind direction adjusting device can be driven to adjust angles of the wind-out blades, so that wind directions can be adjusted conveniently; through an arranged inclining mechanism, an inclining angle of the local ventilator canbe adjusted to correspond to the wind-out angles of the wind-out blades, and the wind direction adjusting device is convenient to use, free from manual adjusting and labor-saving.

Description

technical field [0001] The invention relates to the technical field of air supply and dust reduction equipment of an underground local ventilation system in a coal mine, in particular to an air direction adjustment device for an underground local ventilation fan in a coal mine. Background technique [0002] At present, local ventilators are used to supply air to the working face of the underground mining of coal mines, and dust suppression equipment is used to reduce dust on the working face. During the mining process, a large amount of coal dust is generated on the working face. To reduce dust on the working face, the extraction fan draws the air containing a large amount of coal dust into the dust collector of the dust reduction equipment through negative pressure, and then discharges the clean air through the ventilation pipeline to achieve the purpose of dust reduction on the working face. However, in order to ensure There is sufficient air volume on the working face, an...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the position of the existing local ventilator in the prior art is relatively fixed, so that it is inconvenient to adjust the wind direction when the local ventilator ventilates the underground of the coal mine, thus requiring the staff to manually adjust the local ventilation The wind direction of the fan is cumbersome to adjust and consumes manpower, and a wind direction adjustment device for local ventilation fans in coal mines is proposed.
