Description

Technical Field

[0001] The utility model belongs to the technical field of dust monitoring and early warning equipment, in particular to automatic dust monitoring and early warning equipment suitable for underground cavern construction. Background Art

[0002] Underground cavern construction is an excavation and construction operation in underground rock and soil. A large amount of dust will be generated during blasting, mechanical grinding, rock crushing, etc., which will cause serious harm to the health of workers. Therefore, dust monitoring and early warning equipment is needed to continuously monitor the dust concentration in the air and provide early warning information. However, the existing dust monitoring and early warning equipment has the following deficiencies when used: 1. The existing dust monitoring and early warning equipment is not convenient for dustproofing the equipment. The insufficient sealing of the equipment causes dust to enter the internal circuit and other sensitive components of the equipment, affecting the normal operation of the equipment. At the same time, the operating interface becomes insensitive and difficult to operate due to the accumulation of dust; 2. The dust monitoring and early warning equipment is not convenient for adjusting the height of the equipment, and cannot meet the height requirements of different monitoring points. It is not practical at construction sites with large height changes. Utility Model Content
