Mine ventilation device with alarm device

Abstract

The invention discloses a mine ventilation device with an alarm device, which belongs to the field of mine ventilation devices, and relates to a mine ventilation device with an alarm device. When the gas concentration in the ventilation device is too high, the aromatic hydrocarbon contained in the gas will affect the rubber Corrosion is accelerated by the formation of the fixed ring. The alarm device as a whole falls from the fixed ring inside the gas transmission end and falls into the alarm end. When the alarm device contacts the alarm end, an impact will be generated. The compression spring will absorb a large amount of the above impact. Repeatedly Elongation or shortening will cause the failure of the spatial structure composed of multiple elastic fibers, and multiple activated carbon particles will contact and collide with each other to break up and release the originally stored gas, which will greatly increase the gas concentration in the gas transmission end, making the outlet of the ventilation device The electric methane detection and alarm instrument at the tuyere is easy to detect changes, which can increase the accuracy of gas detection, and is less prone to detection errors and less likely to pose a threat to the life safety of underground miners.

Description

technical field [0001] The invention relates to the field of mine ventilation devices, in particular to a mine ventilation device with an alarm device. Background technique [0002] Mine ventilation refers to the introduction of fresh air into the mine to increase the oxygen concentration to dilute and remove toxic and harmful gases and dust in the mine. The basic tasks of mine ventilation are: to supply enough fresh air underground to meet the oxygen needs of personnel; to dilute harmful gases and dust underground to ensure safe production; to adjust the underground climate and create a good working environment. Cause damage to the geological layer and release the gas stored in the geological layer. Gas accumulation in the mine may easily induce explosion accidents or cause anoxic suffocation of mine workers. Therefore, gas detection equipment must be installed in the mine ventilation device to ensure underground safety. [0003] Gas detection is actually methane detection...

AI Technical Summary

Problems solved by technology

[0004] The accuracy of existing gas detection instruments is already relatively high, but during the detection process, it is easily affected by the external environment, especially the detection device in the ventilation device, which is prone to large errors, which will affect the detection results and affect the underground. poses a serious threat to the lives of miners
