Intelligent coal mine air shaft explosion door experiment device and use method

Abstract

The invention relates to an intelligent coal mine air shaft explosion door experiment device which comprises a transparent experiment shaft, a fan drift, an explosion door, an electromagnetic lock catch, an air distribution mechanism, a high-speed photographing mechanism, a balance weight mechanism and a data acquisition mechanism, the transparent experiment shaft comprises a vertical shaft and a horizontal inflation shaft, and the front end face of the horizontal inflation shaft is connected with the lower end face of the vertical shaft; the explosion-proof door is embedded in the vertical shaft, the upper end face of the explosion-proof door is connected with the counterweight mechanism, the lower end face of the explosion-proof door is connected with the electromagnetic lock catch, a plurality of observation points are arranged on the outer surface of the transparent experiment shaft, each observation point is provided with a high-speed photographing mechanism, and the counterweight mechanism and the data acquisition mechanism are both located outside the transparent experiment shaft. The using method comprises the three steps of equipment assembling, explosion presetting and explosion testing. On one hand, the requirements of explosion-proof operation detection tests of the mine explosion-proof door under various conditions can be effectively simulated; on the other hand, the detection work precision is high, and detection data are comprehensively acquired.

Description

technical field [0001] The invention relates to an intelligent coal mine wind shaft explosion-proof door experimental device and a using method, which belong to the technical field of coal mine explosion-proof and safety management. Background technique [0002] At present, my country's coal mining industry is developing rapidly. Whether mine work can be fully automated is of great significance to mine safety and mining. Explosion-proof doors, as the technical equipment for rapid pressure relief and disaster reduction after gas explosions in mines, are crucial to reducing accident disasters and reducing the expansion of accidents. The explosion-proof door not only needs to have a good pressure relief effect in the event of an explosion, but also cannot be pushed open by the positive pressure generated by the fan when the mine is running against the wind, and must be kept airtight and air-tight. At present, there are still potential safety hazards in the application of coal ...

AI Technical Summary

Problems solved by technology

At present, there are still potential safety hazards in the application of blast-proof doors in coal mine wind shafts, and the specific performance and laws of blast-proof doors are still unclear. Therefore, performance testing and intelligent and automatic control of blast-proof doors are currently problems to be solved.

[0003] Based on the research on traditional explosion-proof doors and lock technology, it is found that traditional explosion-proof doors have problems such as untimely pressure relief and difficulty in automatic reset; in terms of explosion-proof door lock technology, most of the currently used locks are electronically controlled pneumatic locks The biggest problem with this kind of locking device is that the effect and quality of the pneumatic components seriously affect its efficiency, and the locking effect cannot be changed. It is troublesome to replace, cumbersome to operate, and requires a lot of manpower and material resources during the operation.
