A working face air regulating device for underground excavation

Abstract

The invention discloses a working face air regulating device used for underground excavation, and relates to the technical field of mine ventilation devices. The technical solution is as follows: the working face air regulating device for underground excavation includes a ventilation duct main body, the front of the outer wall of the ventilation duct main body is fixedly connected with a control box body, and the front side of the control box body is fixedly connected with a sealing cover through bolts plate, the front of the main body of the ventilation duct is fixedly connected with an installation sleeve, and the front of the installation sleeve is provided with a locking slot, and the inside of the locking slot is slidably inserted with a clamping cylinder, and the clamping cylinder A CO sensor housing is fixedly connected to the back, and a CO sensor is built in the CO sensor housing. The working face air regulating device for underground excavation saves time and effort when installing and fixing the CO sensor casing, and the installation and fixing effect is good, and it is not easy to loosen, and it is also convenient to quickly remove the CO sensor casing for maintenance and maintenance. Maintenance to ensure the stability of the CO sensor housing.

Description

technical field [0001] The invention relates to the technical field of mine ventilation devices, in particular to a working face air regulating device for underground excavation. Background technique [0002] Underground mining operations are mostly at a depth of 200m-1000m below the ground. In order to ensure the safety and normal work of underground workers, it is necessary to continuously deliver fresh air to the underground to ensure the normal breathing of the workers, and at the same time adjust the temperature and temperature of the underground environment. Humidity is used to ensure a good working environment for underground workers. While delivering fresh air, the underground ventilation network is used to discharge harmful gases generated during the operation of underground equipment from the underground roadway. [0003] In the prior art, generally, corresponding ventilation ducts are set up under the mine to ventilate the air under the mine, and in the ventilatio...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, generally, corresponding ventilation ducts are set up under the mine to ventilate the air under the mine, and in the ventilation ducts, a fixed CO sensor can be installed and connected to a computer, so that the computer can be used to measure the CO concentration in the ventilation ducts. Control the speed of the ventilation motor, control the speed of ventilation, and ensure that the motor is in the best working condition. However, the traditional CO sensor is often installed and fixed with bolts. , thus reducing the stability of the CO sensor. When the CO sensor is damaged, the CO sensor cannot be quickly replaced. Aiming at the deficiencies of the prior art, the present invention discloses a working face air regulating device for underground excavation. to solve the above problems
