Automatic mind roadway air volume regulating device

Abstract

The invention discloses an automatic mind roadway air volume regulating device which consists of an air window mechanical hydraulic part and a PLC (Programmable Logic Controller) automatic monitoring part. The air window mechanical hydraulic part comprises air windows, an oil cylinder and an electro-hydraulic push rod. The PLC automatic monitoring part comprises a displacement sensor, a limit switch, an audible and visual alarm, an air volume sensor, an air speed sensor and a PLC electric cabinet. The mechanical hydraulic part is connected with the PLC automatic monitoring part to realize real-time auto-synchronous control of the changes of the linear opening sizes of the front and back air windows of the roadway. The automatic mind roadway air volume regulating device overcomes the disadvantages in mind roadway air volume regulation and achieves the purpose of automatically regulating of the air volume in the roadway.

Description

technical field [0001] The invention relates to an automatic air volume control device, in particular to a real-time automatic air volume control device for mine roadway ventilation systems. Background technique [0002] Existing windshields for adjusting air volume in underground tunnels of coal mines mainly include digital scale windshields, adjustable louver windshields, impeller type precise scale adjustment windshields, button type precise scale adjustment windshields and dial type air volume adjustable windshields. These downhole air volume adjustment windshields often need to manually adjust the air volume according to the needs of production, and ventilation technicians need to manually adjust the windshield after detecting that the air volume in the roadway does not meet the exhaust requirements. Repeated measurement and repeated adjustments can meet the requirements. Manually adjusting the windshield air volume is not only time-consuming and laborious, but the key ...

These downhole air volume adjustment windshields often need to manually adjust the air volume according to the needs of production, and ventilation technicians need to manually adjust the windshield after detecting that the air volume in the roadway does not meet the exhaust requirements. Repeated measurement and repeated adjustments can meet the requirements. Manually adjusting the windshield air volume is not only time-consuming and laborious, but the key is that the adjustment process cannot be adjusted in real time, and the roadway air volume cannot be adjusted to a safe range in a timely and effective manner. The adjustment process often fails to reach expected result
