Underground particle collecting device based on ultrasonic standing waves

Abstract

The invention relates to an underground particle collecting device based on ultrasonic standing waves. The underground particle collecting device comprises a central controller, a terminal server, a detection device and moving devices, wherein the central controller is connected with the terminal server; and the detection device comprises an environment collection and analysis module and a safetymonitoring and analysis module. The underground particle collecting device has the beneficial effects that a certain guide rail is paved in a well passage; a plurality of moving devices are arranged on the guide rail; a sound wave motor is movably connected inside each moving device; the sound wave motor emits standing waves through a sound wave emitter; the standing waves realize good maneuverability on tiny particles, so that suspended particles generate migration movement; the dust removal is more thorough; the directivity is realized; a wave source generator is arranged in a roadway; the particles are concentrated in the wave loop position through the wave vibration; a central air conditioner is installed for exhausting air to form a pipeline standing wave air exhaust system; the defects of the existing roadway dust removal technology are overcome; the potential safety hazards are eliminated; the movable moving devices realize cyclic patrol; and the investigation coverage range islarge.

Description

technical field [0001] The invention relates to the technical field of downhole equipment, in particular to downhole particle collection equipment based on ultrasonic standing waves. Background technique [0002] Mine ventilation technology has appeared in our country for decades. At the same time, with the continuous development of science and technology, and the continuous deepening of people's research on mine ventilation technology, mine ventilation technology has reached a new height. Wind pressure suppresses the diffusion rate of gas in the coal seam. By reducing the gas content in the underground operation channel as much as possible, the pressure equalization technology can realize the production and personnel safety of the working face, especially the high gas coal mine working face. Generally, the pressure difference is reduced to the minimum based on the principle of concentration gradient, so as to reduce or even prevent a large amount of gas gushing out of the g...

AI Technical Summary

Problems solved by technology

Therefore, this technology requires a high level of operation and management measures in the implementation process, so it is subject to certain restrictions in the application process

In addition, although fan pressure equalization has a good effect on suppressing gas gushing, it is not applicable when there is a large external air leakage

[0003] Existing ventilation equipment is always passive ventilation, unable to detect the gas concentration inside the mine, unable to assist ventilation, unable to warn of abnormal gas in advance, and the degree of intelligence is not high
