Coal mine underground ventilation device

Abstract

The invention provides a coal mine underground ventilation device which comprises air exhaust pipelines, an air exhaust fan and an air sucking fan. A protective box body is arranged on a device body;two locking doors are arranged on one side of the protective box body, fixed to the side wall of the protective box body through fixing bolts, and rotatably opened and closed on the protective box body through connecting hinges; the air exhaust fan is arranged on the inner side of one of the locking door in an embedded mode, a storage power supply is arranged at the bottom of the inner side of theother locking door in an embedded mode and electrically connected with the air exhaust fan and the air sucking fan, and an outage control panel is further mounted on the side wall of the inner side of the other locking door; and a locking door is fixed to the other side of the protective box body through fixing bolts, and the air sucking fan is arranged on the inner side of the locking door in anembedded mode. According to the coal mine underground ventilation device, the arranged storage power supply can continuously provide necessary power supplies for the air sucking fan and the air exhaust fan under the condition of outage of the device, and thus continuous fresh air is conveniently provided for the interior of a coal mine.

Description

technical field [0001] The invention relates to the technical field of coal mine ventilation equipment, in particular to an underground coal mine ventilation device. Background technique [0002] In the process of coal mining, as the depth of the mine gradually increases, there will be more and more harmful gases inside, and the air will become less and less. At this time, the coal workers working in the mine will have difficulty breathing, which is prone to accident Therefore, it is necessary to set up an underground ventilation device to discharge harmful gases in the well and inject fresh air into it. [0003] The inventors found that the existing coal mine underground ventilation device has the following problems: lack of ventilation device protection device, the internal exhaust fan and exhaust fan are easily damaged; the compressive strength of the exhaust pipe is slightly low, and cannot To ensure the smoothness of the gas; they are all equipped with a reserve power ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of coal mine underground ventilation device, to solve the lack of ventilation device protection device proposed in the above-mentioned background technology, the internal exhaust fan and exhaust fan are easily damaged; the compressive strength of the exhaust pipe is slightly low, Unable to ensure the smoothness of the gas in the event of an accident; all are equipped with a reserve power supply, which cannot continue to operate after a power failure, and cannot continue to provide fresh air for the mine
