Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air supply and dust reduction equipment of a local ventilation system in an underground coal mine, in particular to a wind direction regulating device for a local ventilator in an underground coal mine. Background Art
[0002] At present, local fans are used to supply air to the working faces of underground coal mines, and dust reduction equipment is used to reduce dust on the working faces. A large amount of coal dust is generated on the working faces during mining. In order to reduce the coal dust on the working faces, dust reduction equipment with exhaust fans is used to reduce dust on the working faces. The exhaust fans use negative pressure to draw air containing a large amount of coal dust into the dust collector of the dust reduction equipment for dust reduction, and then discharge the clean air through the ventilation duct to achieve the purpose of dust reduction on the working faces. However, in order to ensure that there is sufficient air volume on the working faces, local fans send the air volume directly to the working faces through the ventilation ducts, causing disordered disturbances in the wind flow on the working faces, which in turn causes unlimited diffusion of coal dust, which is not conducive to the exhaust fans to concentrate the coal dust into the dust removal equipment for dust reduction.
[0003] The position of the existing local ventilator is relatively fixed, which makes it difficult to adjust the wind direction when the local ventilator is ventilating underground in a coal mine. As a result, workers are required to manually adjust the wind direction of the local ventilator, which is troublesome and consumes manpower. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0023] Example 1
[0024] Please refer to Figure 1 The present embodiment provides a wind direction regulating device for a local ventilation fan in an underground coal mine, which comprises a ventilation device 1 and a wind direction regulating cover, wherein the wind direction regulating cover comprises an regulating air duct 2 and a plurality of wind direction regulating plates 3, wherein the regulating air duct 2 is hooded at the air outlet of the ventilation device 1, and the regulating air duct 2 is rotatably connected to the ventilation device 1, the wind direction regulating plates 3 are arranged at intervals in the ventilation device 1, and the wind direction regulating plates 3 are hinged to the regulating air duct 2, two adjacent wind direction regulating plates 3 are movably connected by a connecting rod 4, and a movable regulating member 5 is arranged at one end of any wind direction regulating plate 3, and a sliding card slot 6 is correspondingly opened on the regulating air duct 2, and the movable regulating member 5 is slidably arranged in the sliding card slot 6.
[0025] In this embodiment, the ventilation device 1 is an existing local ventilator, and the ventilator is connected to the ventilation duct to achieve the ventilation effect. The wind direction adjustment cover is used to adjust the air outlet direction, and can be directly installed at the air outlet of the existing ventilation device 1, without changing the existing equipment, saving costs and convenient installation. Specifically, the wind direction adjustment cover includes an adjustment air duct 2, and the adjustment air duct 2 is rotatably connected to the ventilation device 1, and the adjustment air duct 2 can be manually rotated to change the direction of the adjustment air duct 2. A plurality of wind direction adjustment plates 3 are arranged at intervals in the adjustment air duct 2, and the two ends of the wind direction adjustment plates 3 are hinged to the inner side wall of the adjustment air duct 2. Two adjacent wind direction adjustment plates 3 are movably connected by a connecting rod 4 to form a linkage structure. When any of the wind direction adjustment plates 3 rotates, all the wind direction adjustment plates 3 rotate synchronously under the action of the connecting rod 4, and the airflow flowing out of the ventilation device 1 changes direction under the action of the wind direction adjustment plates 3, thereby adjusting the air outlet direction. A movable adjusting member 5 is provided at one end of any of the wind direction adjusting plates 3 , and a manual control effect is achieved through the movable adjusting member 5 , so as to change the angle of the wind direction adjusting plate 3 and adjust the air outlet direction.
[0026] When in use, the regulating air duct 2 and the wind direction regulating plate 3 form a linkage effect. The operator adjusts the inclination angle of the wind direction regulating plate 3 through the movable regulating member 5, thereby changing the air outlet direction. Since the wind direction regulating plate 3 can only rotate in one direction, the air outlet is changed from the up and down directions. At this time, only the regulating air duct 2 needs to be rotated to rotate the regulating plate to any angle, thereby adjusting the wind direction to any desired direction.
[0027] Furthermore, in some implementations of the present embodiment, the movable adjusting member 5 includes a limiting rod 7 and a fixed spring 8, a slide groove 9 is opened at one end of the wind direction adjusting plate 3, the limiting rod 7 is slidably set in the slide groove 9, the fixed spring 8 is set in the slide groove 9, and one end of the fixed spring 8 is connected to the limiting rod 7, and the other end is connected to the adjusting air duct 2.
[0028] The sliding slot 6 is a "∏"-shaped slot, and the limiting rod 7 can slide in the sliding slot 6, and the angle of the wind direction adjustment plate 3 can be changed and fixed to the adjusting air duct 2 by adjusting the position of the limiting rod 7. When it is necessary to adjust the angle of the wind direction adjustment plate 3, slide the limiting rod 7 so that the limiting rod 7 falls off the sliding slot 6, and the fixing spring 8 is in a stretched state. Then rotate the limiting rod 7 to adjust the angle of the wind direction adjustment plate 3 to change the air outlet direction, and then release the limiting rod 7. Under the elastic force of the fixing spring 8, the limiting rod 7 is snapped into another position of the sliding slot 6 to fix the wind direction adjustment plate 3, thereby preventing the wind direction adjustment plate 3 from rotating again during use. Repeat the above operation when the wind direction needs to be adjusted again.

A gear ring 12 is correspondingly provided on the outer wall of the regulating air duct 2, and the driving gear 11 and the gear ring 12 are meshed with each other.
[0031] In this embodiment, the driving motor 10, the driving gear 11 and the ring gear 12 form an automatic control system. The regulating air duct 2 is rotated by the driving motor 10 without manual operation, and the rotation angle of the regulating air duct 2 can be adjusted by controlling the working time of the driving motor 10. The driving motor 10 can be an existing stepping motor, and the rotation angle of the regulating air duct 2 can be controlled by connecting to an external control system, which can save labor and accurately and smoothly control the stop angle of the regulating air duct 2 to ensure the accuracy of the air outlet direction.

The supporting frame 13 supports the adjusting air duct 2, and the height of the adjusting air duct 2 can be adjusted by the lifting and adjusting rod 14, so as to facilitate the connection and installation of the adjusting air duct 2 with the existing ventilation device 1.
[0035] Optionally, in some implementations of this embodiment, a moving wheel 15 is provided on the support frame 13. The moving wheel 15 can be a universal wheel to facilitate moving the support frame 13.
[0036] Optionally, in some other embodiments, the air outlet cover of the regulating air duct 2 is provided with a protective mesh cover 16.
