Abstract

The invention discloses a coal mine underground ventilation regulating device, which relates to the technical field of coal mine underground ventilation facilities. Including damper, two dampers, base plate is set at the bottom of the two dampers, door body is set on the base plate, openings are set on the damper, frame is set inside the damper, motor is set inside the frame, coupling is set on the motor, and the coupling is far away from the motor A rotating rod is arranged at one end of the output shaft, a rotating disc is arranged on the rotating rod, a push-pull rod is arranged on the rotating disc, a through hole is arranged on the frame, and the device also includes a substrate; a supporting frame is arranged on one side of the substrate, a photoelectric sensor is arranged on the supporting frame, and a sensor The base plate is provided with an airtight frame, the bottom plate is located in the airtight frame, and the bottom of the bottom plate is provided with a bottom plate lifting adjustment device, and the device also includes a control system. The beneficial effect of the present invention is that: the control system controls the photoelectric sensor, the motor and the bottom plate lifting adjustment device, and then controls the chain opening and closing of the two air doors, which saves time and improves the ventilation efficiency.

Description

technical field [0001] The invention mainly relates to the technical field of coal mine underground ventilation facilities, in particular to a coal mine underground ventilation regulating device. Background technique [0002] The damper is an important equipment that can not only cut off the wind flow, but also pass vehicles and pedestrians underground in coal mines. It mainly realizes the control of the wind flow underground. The coal mine underground damper requires at least two doors. Only when one damper is closed can the other be opened, that is, the two doors cannot be opened at the same time, otherwise it will cause air leakage or short circuit, which will affect the mine ventilation system. [0003] In the prior art, in order to reduce the roadway space occupied by the damper and improve the efficiency of coal mine mining, the patent 201810098857.X discloses a locking device for the damper under the coal mine, including the first damper and the second damper. A fixed...
