Problems solved by technology

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

Embodiment Construction

[0025] The specific embodiments of the present invention will be further described below in conjunction with the drawings.

[0026] The automatic control device for mine tunnel air volume provided by the present invention includes two wind windows, two oil cylinders, two electro-hydraulic push rods, two displacement sensors, four limit switches, one sound and light alarm, three Typhoon volume sensor, three wind speed sensors, one PLC electric control cabinet. The windshield structure and the air volume adjustment principle of the front and rear windshields of the roadway are the same, and the linear opening size change control process of the front and rear windshields is real-time automatic synchronization control. This embodiment only takes an automatic wind window air volume adjustment device as an example to illustrate the structural features of the wind window air volume automatic adjustment device of the present invention, as well as the installation position of the wind win...

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 air volume automatic control device, in particular to a real-time automatic control device for air volume in a mine tunnel ventilation system. Background technique [0002] Existing coal mine tunnel air volume adjustment windshields mainly include digital scale windshield, adjustable louver windshield, impeller type precision scale adjustment windshield, button type precision scale adjustment windshield and wheel type wind volume adjustable windshield. These underground air volume adjustment windows are often required to manually adjust the air volume according to the needs of production, and the ventilation technicians need to manually adjust the wind windows after detecting that the air volume in the tunnel does not meet the exhaust requirements, and each time the air volume is adjusted Repeated measurement and repeated adjustments can meet the requirements. Manually adjusting the air volume of the windshield is not only time-c...
