Description

Technical Field

[0001] This utility model relates to the field of safety monitoring, and in particular to a gas outburst parameter instrument. Background Technology

[0002] A gas outburst parameter meter is an important device used to monitor the risk of gas outbursts in coal mines. By monitoring relevant parameters in real time, it helps determine whether a gas outburst is likely to occur in the mine. Its purpose is to provide early warning before the gas concentration reaches dangerous levels, thereby ensuring the safety of miners and reducing the occurrence of accidents.

[0003] Traditional gas outburst parameter instruments typically include gas detection devices, data acquisition systems, and alarm systems. These components enable real-time monitoring of parameters such as gas concentration and pressure, and issue alarms when anomalies are detected. These components work together to ensure timely detection and feedback of safety conditions in the mine.

[0004] Traditional gas outburst parameter instruments are inefficient, often relying on manual settings and adjustments. Furthermore, monitoring multiple parameters requires separate equipment, resulting in slow data processing and response times. Due to equipment limitations and insufficient accuracy, false alarms or missed detections can occur. This inefficient detection method fails to capture subtle changes in the early stages of a gas outburst, impacting the timeliness and accuracy of safety warnings and hindering the effective prediction of gas outburst risks. This can lead to sudden gas accidents in mines, seriously threatening miners' lives. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a gas outburst parameter instrument, which aims to improve the problem that the low detection efficiency of traditional gas outburst parameter instruments leads to sudden gas accidents in mines, seriously threatening the lives of miners.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a gas outburst parameter instrument, comprising:

[0007] The main unit of the parameter instrument;

[0008] Five coal sample control knobs are distributed on the surface of the parameter instrument main unit, which independently control the detection process of the corresponding coal sample container;

[0009] The central display screen, embedded in the main unit of the parameter instrument, synchronously displays the gas data of multiple coal sample tanks;

[0010] A quick-connect airtight interface group is connected to each of the coal sample control knobs for airtight connection of the coal sample container.

[0011] As a further description of the above technical solution:

[0012] The rotating shaft of the coal sample control knob is provided with a limiting boss, which cooperates with the arc-shaped limiting groove on the inner wall of the parameter instrument host to limit the knob's rotation overtravel.

[0013] As a further description of the above technical solution:

[0014] The central display screen is fixed to the main unit of the parameter instrument by a shock-resistant mounting structure to absorb vibration and impact.

[0015] As a further description of the above technical solution:

[0016] The quick-connect airtight interface group has a built-in sealing structure to ensure airtightness when the coal sample container is connected.

[0017] As a further description of the above technical solution:

[0018] The limiting boss and the arc-shaped limiting groove are a matching fan-shaped structure, which improves the limiting accuracy and service life of the knob rotation.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, five independent coal sample control knobs and quick-connect airtight interface groups are used to realize the synchronous detection of five coal samples, which shortens the detection time compared with the traditional single tank detection mode. The central display screen compares the data of multiple tanks in real time, improving the efficiency of gas outburst parameter analysis.

[0021] 2. In this utility model, the mechanical cooperation between the limiting boss and the arc-shaped limiting groove controls the knob rotation angle error to a very small range, preventing misoperation from causing detection interruption; the sealing design of the anti-vibration embedded structure and the quick-connect airtight interface group enables the equipment to maintain stable operation in the vibration environment of coal mines and reduces the frequency of maintenance.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-3 One embodiment of this utility model is a gas outburst parameter instrument, comprising:

[0029] Parameter instrument main unit 1;

[0030] Five coal sample control knobs 2 are distributed on the surface of the parameter instrument host 1, which independently control the detection process of the corresponding coal sample tank;

[0031] The central display screen 3 is embedded in the parameter instrument host 1 and synchronously displays the gas data of multiple coal sample tanks;

[0032] The quick-connect airtight interface group 4 is connected to each coal sample control knob 2 for airtight connection of the coal sample container. The rotation shaft of the coal sample control knob 2 is equipped with a limiting boss 5, which cooperates with the arc-shaped limiting groove 6 on the inner wall of the parameter instrument host 1 to limit the knob rotation overtravel. The central display screen 3 is fixed to the parameter instrument host 1 through the anti-vibration embedding structure 7 to absorb vibration and impact. The quick-connect airtight interface group 4 has a built-in sealing structure to achieve airtightness when the coal sample container is connected. The limiting boss 5 and the arc-shaped limiting groove 6 are adapted fan-shaped structures to improve the limiting accuracy and service life of the knob rotation.

[0033] Working principle: The gas outburst parameter instrument carries five coal sample control knobs 2 and a central display screen 3 via the instrument host 1. Each knob 2 is independently connected to a coal sample container via a quick-connect airtight interface group 4. The limiting boss 5 on the knob rotation shaft cooperates with the arc-shaped limiting groove 6 on the inner wall of the host to achieve rotation limit and prevent misoperation. During testing, the knob 2 controls the start and stop of the testing process of the corresponding coal sample container. The gas data is processed internally by the host and then displayed synchronously on the central display screen 3. The display screen is fixed by an anti-vibration embedding structure 7 to adapt to the vibration environment of the coal mine site. The built-in sealing structure of the quick-connect airtight interface group 4 ensures the airtightness when the coal sample containers are connected, thereby realizing the parallel testing and real-time data monitoring of five coal samples, which greatly shortens the testing time.
