Description

Ventilation device for preventing coal mine gas from exceeding limit Technical Field The utility model relates to the technical field of ventilators, in particular to a ventilation device for preventing coal mine gas from exceeding the limit. Background Coal is taken as an important energy resource in China and occupies a significant position in national economic development. However, there are a number of potential safety hazards faced during coal mining, where the problem of gas overrun is one of the major threats to coal mine safety production. The gas is common combustible gas in coal mines, when the gas concentration exceeds the safety limit, serious accidents such as explosion or poisoning are extremely likely to be caused, and not only can huge economic loss be caused, but also serious threat is caused to the life safety of miners. In order to effectively prevent the gas of the coal mine from exceeding the limit and ensure the safe production of the coal mine, the ventilation device plays a vital role in the coal mining. The ventilator is used as core equipment of the ventilation system of the coal mine, and can continuously supply fresh air on the ground to a mine operation site under the action of mechanical or natural power, so that toxic and harmful gases and dust are diluted and discharged, the climate conditions in the mine are regulated, and a safe and comfortable working environment is created for miners. Currently, various types of ventilation devices for preventing coal mine gas overrun exist on the market. These devices can meet the basic requirements of coal mine ventilation to some extent, but have some disadvantages in practical application. Because the underground working environment of the coal mine is complex and severe, the ground is generally uneven, and most of the existing ventilation devices for preventing the gas of the coal mine from exceeding the limit are unstable when moving on the ground. The instability not only can affect the normal use of the ventilation device and reduce the ventilation efficiency, but also can cause the aggravation of the abrasion of the internal parts of the device and shorten the service life of the device. Moreover, during movement, an unstable ventilation device may also present a safety hazard, which poses a threat to the safety of the operator. In addition, some existing ventilation devices have certain disadvantages in terms of adjustment of ventilation direction and safety protection. The inconvenience of ventilation direction adjustment can lead to the ventilation effect not good, can not carry fresh air to the region of needs effectively to influence the dilution and the discharge effect of gas. Insufficient safety protection may expose operators to risk of injury during use, and is also detrimental to routine maintenance and cleaning of the device. In summary, the existing ventilation device for preventing the coal mine gas from exceeding the limit cannot well meet the actual requirements of coal mine safety production. Therefore, the development of the ventilation device which is stable in movement, flexible in ventilation direction and good in safety protection and can prevent the gas of the coal mine from exceeding the limit has important practical significance, and has positive pushing effect on improving the safety production level of the coal mine.
