Description

Technical Field

[0001] The utility model relates to the technical field of coal mine ventilation, in particular to intelligent control equipment for coal mine ventilation. Background Art

[0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, people generally choose to directly strip the surface soil layer to mine coal. This is an open-pit coal mine. Most of my country's coal mines are underground coal mines. Coal mine ventilation is to supply enough fresh air underground to meet the workers' needs for oxygen, dilute harmful gases and dust underground, ensure safe production, and at the same time adjust the underground climate to create a good working environment.

[0003] At present, coal mine ventilation equipment needs to be manually turned on when in use. It does not have the function of detecting the air content in the mine. When the mine does not need to supply air, the coal mine ventilation equipment cannot stop working in time. When the mine needs to supply air, the coal mine ventilation equipment cannot be turned on in time, which causes inconvenience to the ventilation work of the coal mine. Utility Model Content

[0004] The purpose of the utility model is to provide intelligent control equipment for coal mine ventilation, which has the advantages of being able to detect the air content in the mine and to promptly open and close the coal mine ventilation equipment for ventilation work, thereby solving the problems raised by the above-mentioned background technology.

Air can be blown when the fan blades rotate at high speed, and the air in the mine can be transported to a gas detector. The air in the mine can be detected by the gas detector, and the air content in the mine can be detected. When the amount of oxygen is insufficient or the amount of harmful gas is excessive, the mine ventilation equipment is controlled to be turned on for ventilation. When the air in the mine is detected, the threaded rod can be made to rotate by the operation of the first driving device, and the movable block can be moved up and down when the threaded rod rotates, so that the air at different heights in the mine can be detected, and the accuracy of gas detection can be improved.

[0008] Preferably, a mounting hole is opened at the upper end of the base plate, and there are four mounting holes in total, and the four mounting holes are distributed in an array with respect to the base plate.
