Description

Adaptive mine air pressure self-rescue device

technical field

The invention relates to an underground safety self-rescue device, in particular to an adaptive mine air pressure self-rescue device.

Background technique

At this stage, when working underground in coal mines, when dangerous situations such as the sudden outflow of harmful gases, roof fall, and collapse occur in the workplace, the on-site personnel have no time to evacuate. Awaiting rescue.

The existing general mine air pressure self-rescue devices have basically the same mode and single function. Especially after a mining accident occurs in a mine tunnel, the environment is dim and the activity space is small. Without understanding the actual situation on the site, the trapped people inside are prone to emotions such as fear and anxiety. If these emotions are not quickly stabilized, it is likely to cause the trapped people. Psychological problems, and even self-defeating. There is an urgent need for a high-safety mine air pressure self-rescue device, which can stabilize the emotions of trapped people while breathing clean air and waiting for rescue.

SUMMARY OF THE INVENTION

Aiming at the deficiencies of the prior art, the present invention provides an adaptive mine air pressure self-rescue device, which can adapt to the requirements of complex underground environments, and when encountering a sudden surge of harmful gas, the trapped persons can breathe clean air and at the same time understand the trapped site in real time. situation, reduce the psychological emotions of the trapped people, and make corresponding treatment plans.

In order to solve the above-mentioned technical problems, the present invention is an adaptive mine pressure air self-rescue device, which includes a box body, and the box body has a built-in air intake main pipe, and the air intake main pipe is connected with a number of self-priming masks; The suction mask is provided with a ball valve, a pressure gauge and a filter in sequence; the intake main pipe, the ball valve, the pressure gauge, the filter and the self-priming mask are connected; the box body is movable with a box cover; the intake main pipe External air source.

Preferably, a gas monitor is provided outside the box.

Preferably, the ball valve is communicated with the filter by a copper pipe, and the filter is communicated with the self-priming mask by a hose.

Preferably, a pressure reducing valve is arranged between the ball valve and the pressure gauge.

The box body of the invention is arranged in the places where people escape, such as tunnels, caves, etc. When disaster occurs, it is convenient for trapped people to quickly enter and open the box cover, and put on a breathing mask for self-rescue. When in use, open the ball valve and wear a self-priming mask for breathing. The ball valve is installed under the intake main pipe and connected to the filter, which is convenient to use; the pressure reducing valve can quickly adjust the air pressure according to the air pressure and air supply volume adapted to the individual.

In order to stabilize the emotions of the trapped people, a gas monitor is also installed in the present invention. When a gas explosion occurs in the mine, the gas concentration in the roadway exceeds the standard and is filled with toxic gases. People in the sealed space are prone to become anxious and irritable because they cannot grasp the actual situation. wait for negative emotions. After the gas monitor of the invention is turned on, it can monitor the harmful gas content in the disaster space in real time, help the trapped people to grasp the specific situation of the disaster space in real time, and improve the survival probability of the trapped people through real-time data analysis and determination of subsequent self-rescue methods. .

The beneficial effects of the present invention: compared with the prior art, the present invention can realize the self-rescue of personnel when underground gas explosion and concentration exceeds the standard by installing multiple self-rescue devices in the mine safety chamber; The trapped people can judge the safety of the space they are in in real time, and take corresponding measures in time to improve the probability of the trapped people getting out of trouble.

Detailed ways

Below in conjunction with accompanying drawing, the present invention is described in further detail:

As shown in FIG. 1, an adaptive mine air pressure self-rescue device of the present invention includes a box body 1, and the box body 1 has a built-in air intake main pipe 2, and the air intake main pipe 2 is connected with a number of self-priming masks 6; The intake main pipe 2 to the self-priming mask 6 are sequentially provided with a ball valve 3, a pressure gauge 4, and a filter 5; the intake main pipe 2, the ball valve 3, the pressure gauge 4, the filter 5, and the self-priming mask 6 The box body 1 is movably provided with a box cover 11 ; the air intake main pipe 2 is connected to an external air source.

A gas monitor 8 is arranged outside the box body 1 .

The ball valve 3 is communicated with the filter 5 by a copper pipe 9 , and the filter 5 is communicated with the self-priming mask 6 by a hose 10 .

A pressure reducing valve 7 is arranged between the ball valve 3 and the pressure gauge 4 .

When working, open the box cover 11, take out the self-priming mask 6 and wear it well, open the ball valve 3 and purify the air into the self-priming mask 6 for the trapped person to breathe, rotate the opening angle of the ball valve 3 to adjust the appropriate air supply, and the pressure gauge 4 Real-time display of the air pressure for the trapped personnel to breathe, and the trapped personnel can also adjust the air pressure by rotating the pressure reducing valve 7 according to their personal comfort.

The gas monitor 8 is installed on the right side of the box 1. When the gas explosion occurs in the well and the concentration exceeds the standard, the trapped person quickly opens the box cover 11 and takes out the self-priming mask 6 for use. Display the gas concentration at the trapped site, help trapped people understand the environment of the trapped space, and stabilize their anxiety. When the gas concentration drops to the normal value, the trapped people can have more ways to rescue themselves while waiting for rescue.

The invention has the advantages of simple structure, safe and convenient use, can significantly improve the survival probability of people who are trapped in the mine, and has strong practicability.

The foregoing has shown and described the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments, and the descriptions in the above-mentioned embodiments and the description are only to illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have Various changes and modifications fall within the scope of the claimed invention.
