Problems solved by technology
However, at present, the monitoring of the air flow parameters of the windshield and the adjustment of the flow area of the windshield in coal mines in my country are basically manual operations. The adjustment process is time-consuming and laborious, and the efficiency is very low, and the reliability and stability are poor.
[0004] To sum up, at present, there is no time-saving, labor-saving, high-efficiency, high-precision coal mine windshield air volume adjustment monitoring system and method in the prior art

A regulation and monitoring system for the air volume of air windows on a coal mine comprises a box body, flow guide plates, pneumatic adjustment mechanisms, an air speed monitoring mechanism, the air windows and a signal control system, wherein the box body is mounted in a roadway, and the shape and the area of a cross section of the box body are the same as those of a cross section of the roadway; the two flow guide plates are vertically mounted in the box body, the front ends of the flow guide plates are hinged to two flat plates of the air windows respectively, and the middles and the rear ends of the flow guide plates are hinged with two sides of the box body; the pneumatic adjustment mechanisms are mounted at front ends of the box body and hinged with the air windows, and the pneumatic adjustment mechanisms control the two flat plates of the air windows to be opened and closed; the air speed monitoring mechanism is mounted at the rear half part of the box body. According to the regulation and monitoring system for the air volume of the air windows on the coal mine, monitoring and adjustment of the air volume of the air windows are integrated, the air volume of the air windows is adjusted more efficiently, labor is saved, and the adjustment precision is high.
Description
technical field [0001] The invention relates to an adjustment and monitoring system, in particular to an air volume adjustment and monitoring system for windshields in coal mines. Background technique [0002] Concurrent ventilation in coal mines is one of the most important technical means to ensure mine production safety. With the continuous development and change of production, the working face is constantly advancing and replacing, the wind resistance of the roadway, the network structure and the required air volume are constantly changing, the natural distribution of the air volume of the roadway often cannot meet the air volume demand of the work place, so it must be Adjust the air volume in time for the underground roadway network. Therefore, air volume adjustment is a regular task in the technical management of underground ventilation in coal mines, and it has a significant impact on mine production safety and ventilation energy consumption. [0003] Adjusting the ...
