Abstract
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...
Examples
Embodiment 1
[0031] The embodiment of the invention discloses a working face air regulating device for underground excavation, such as figure 1 , 4 As shown, the main body 1 of the ventilation duct is included, and the front of the outer wall of the main body of the ventilation duct 1 is fixedly connected with the control box body 2. The sleeve 4, the front of the installation sleeve 4 is provided with a locking slot 401, and the inside of the locking slot 401 is slidably inserted with a clamping cylinder 5, and the back of the clamping cylinder 5 is fixedly connected with a CO sensor housing 6, a CO sensor housing 6 A CO sensor is built in the interior of the CO sensor, and a protective cover 602 is fixedly installed on the CO sensor housing 6. The clamping cylinder 5 passes through the clamping groove 401 and the outer wall of the ventilation duct main body 1 and extends into the inner cavity of the ventilation duct main body 1. Both sides of the cylinder 5 are fixedly connected with si...
