Abstract

The invention discloses a gas early-warning and monitoring device for coal mine safety production and a method of use thereof, comprising an early-warning box, a protection mechanism, a gas detector and a spare detector, one side of the early-warning box is provided with an installation slot, and the gas detector In the installation groove, the spare detector is set in the early warning box, and the protective mechanism is set on the early warning box. The protective mechanism includes a connecting support, a mounting plate, a telescopic rod, a folding protective component and a power transmission component, and the connecting support is symmetrical. It is installed on the top wall of the early warning box. There are two sets of mounting plates and the middle parts are respectively rotated on the connecting support. The telescopic rod is hinged on the side wall of the early warning box and is hinged on the mounting plate. The two groups are respectively arranged on the two groups of mounting plates, and the power transmission component is arranged in the early warning box and connected with the folding protection component and the spare detector. The invention relates to the technical field of coal mine safety production, and in particular provides a gas early warning and monitoring device for coal mine safety production and a use method thereof.

Description

technical field [0001] The invention relates to the technical field of coal mine safety production, in particular to a gas early warning and monitoring device for coal mine safety production and a use method thereof. Background technique [0002] Gas seriously threatens the safe production of coal mines. In order to improve coal mine safety production, mine safety production has been promoted. It is necessary to monitor the concentration of coal mine gas to ensure that managers can find it in time. However, the existing coal mine gas early warning and monitoring device only has a set of detectors during the patrol monitoring process. Once it is damaged by explosion impact or collapse and falling rocks, it can no longer monitor the concentration, resulting in the inability to understand the follow-up situation in time and affecting the efficiency of event handling.

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a coal mine safety production gas early warning monitoring device and its use method for efficient protection when the mine tunnel explodes or collapses. After the gas detector is damaged due to impact , based on the principle of mechanical energy replacement, abandoning the traditional way of using sensors to start, only using a simple mechanical mechanism to realize the action of starting the backup detector when the rockfall impacts, completing the continuous and uninterrupted detection of gas detection, and overcoming the common detection method Once the gas detector is damaged, the follow-up detection cannot be completed, so the management personnel cannot timely understand the environmental conditions in the roadway, so as to take correct and fast measures to deal with it; adopt the principle of prior action to unfold the folding protective components after entering the roadway to prevent For the impact of falling rocks, use the impact protection plate to disperse the impact force before evenly transmitting it to the elastic damper and the transmission airbag, and achieve an efficient cushioning effect by dispersing the impact force; when the transmission airbag receives the squeeze impact, the pressure increases and it is easy to crush The transmission airbag leads to the contradictory characteristics that the cushioning effect cannot be sustained. Through the principle of contradiction transfer, the gas under high pressure of the transmission airbag is creatively introduced into the V-shaped transmission pipe, and the V-shaped transmission pipe is used to accelerate the airflow, converting the kinetic energy of the airflow into light weight. The kinetic energy of the blocking ball is used to pierce the air bag 1 and the air bag 2, and through the mixed reaction of the components in the air bag 1 and the air bag 2, a large amount of gas is generated again to open the blocked air inlet of the spare detector, and the transmission is perfectly driven. The disadvantage of overpressure and explosion of the airbag is transformed into the advantage of being able to activate the backup detector
