Problems solved by technology

[0003] When carrying out the gas countercurrent outburst experiment, it is usually necessary to ensure the opening and closing of the outburst. In the existing gas backflow test device, the operator manually opens and closes the overhang, which is slow and inconvenient to automatically open the overhang. and closing will affect the protrudin

Abstract

The invention discloses a gas countercurrent test device based on roadway network outburst mouth self-opening. The device comprises a bracket, a gas tank and a high-frequency pressure shock wave sensor. The gas tank is fixed on the bracket, the output end of the gas tank is connected with an outburst box body through a high-pressure gas pipe, and a valve is mounted on the high-pressure gas pipe. Apressure relief box is mounted at one end of the outburst box body in a penetrating manner, and an outburst opening is formed between the pressure relief box and the outburst box body. A storage groove is formed in the bottom of the interior of the pressure relief box, an extrusion plate is in shaft connection with the interior of the storage groove, a telescopic groove is formed in the outer side of the extrusion plate, and an electric push rod is in shaft connection with the interior of the storage groove. A dust collection assembly is installed at one end of a roadway pipe. According to the gas countercurrent test device based on roadway network outburst mouth self-opening, automatic opening of the outburst mouth can be completed, the gas outburst simulation effect is improved, meanwhile, shock absorption and buffering are conducted on the device, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of gas counterflow test, in particular to a gas counterflow test device based on the self-opening of a roadway network protrusion. Background technique [0002] When gas is being produced in a mine, sometimes there will be an outburst gas backflow situation. During the outburst development process, a large amount of gas that suddenly gushes out can not only form a high-pressure gas flow, but also form air shock waves at the front of the outburst. In order to evaluate the impact of the shock wave Overpressure has a destructive effect on the underground anti-draft door, ventilation facilities, and the killing effect on personnel, and a gas backflow test is required. However, the existing gas backflow test device has the following problems in use: [0003] When carrying out the gas countercurrent outburst experiment, it is usually necessary to ensure the opening and closing of the outburst. In the existing gas ...
