Description

Technical Field

[0001] This utility model relates to the field of coal mine monitoring technology, specifically to a multi-parameter monitoring device for a closed area in a coal mine. Background Technology

[0002] Mining areas, whether in operation or abandoned, are typically enclosed by airtight walls to isolate the space. These walls serve several purposes: preventing the spread of harmful gases, controlling inefficient airflow to improve ventilation system efficiency, preventing the leakage or spread of groundwater and slurry, and reducing the incidence of mine accidents. However, these enclosed spaces require frequent monitoring of temperature and the presence of toxic and harmful gases during mine operations to prevent disasters such as spontaneous combustion of coal and explosions in confined spaces.

[0003] Since the concentrations of harmful or flammable gases at the top and bottom of a mine are different, traditional multi-parameter monitoring devices have a relatively single gas collection direction. Existing multi-parameter monitoring devices can only collect gas in one direction, which directly affects the accuracy of the multi-parameter monitoring device. In severe cases, it can directly cause poisoning and explosions, leading to safety accidents. Therefore, a multi-parameter monitoring device for closed areas in coal mines is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a multi-parameter monitoring device for enclosed areas in coal mines to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a multi-parameter monitoring device for a closed area in a coal mine, comprising a monitoring instrument body, a multi-directional acquisition component is provided at the middle position of the top side and the middle position of the bottom side of the monitoring instrument body, and a negative pressure component is provided at the middle of both sides of the multi-directional acquisition component, and the two multi-directional acquisition components are respectively connected to the two negative pressure components through the monitoring instrument body; Each of the multi-directional acquisition components includes a circular air inlet pipe, which is fixedly connected to the main body of the monitoring instrument and communicates with the main body of the monitoring instrument. An internally threaded connecting pipe is fixedly connected to the outer side of the circular air inlet pipe near the top. The internally threaded connecting pipe is internally threaded to a multi-directional acquisition pipe, which is Y-shaped and has two air inlets. A circular filter plate is fixedly installed at both ends of the two air inlets.

[0006] As a further improvement to this technical solution, each of the negative pressure components includes a circular exhaust pipe, which is fixedly connected to the main body of the monitoring instrument and communicates with the main body of the monitoring instrument. A circular mounting pipe is fixedly inserted into the outside of the circular exhaust pipe, and the circular exhaust pipe communicates with the circular mounting pipe.

[0007] As a further improvement to this technical solution, a mounting bracket is fixedly connected to the inner wall of the mounting circular tube, and a drive motor is fixedly installed at the middle position of one side of the mounting bracket. The output shaft of the drive motor passes through the drive motor, and the output shaft of the drive motor is rotatably connected to the mounting bracket. A negative pressure fan blade is fixedly sleeved at the end of the output shaft of the drive motor.

[0008] As a further improvement to this technical solution, a rectangular display screen and multiple circular control buttons are provided on one side of the main body of the monitoring instrument. The multiple circular control buttons are located at the bottom of the rectangular display screen. The rectangular display screen is used to display gas parameters, and the circular control buttons are used to control the main body of the monitoring instrument and set the parameters of the main body of the monitoring instrument.

[0009] As a further improvement to this technical solution, power supply ports are provided on both sides of the main body of the monitoring instrument. The two power supply ports are located on the top of the two negative pressure components, and the two power supply ports supply power to the main body of the monitoring instrument.

Mounting holes are provided on one side of the mounting plate near the edge, and the two mounting holes are symmetrically arranged. The mounting plate is fixed in the mine through the two mounting holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In multi-parameter monitoring devices for confined areas of coal mines, existing multi-parameter monitoring devices have shortcomings in gas collection. By setting up two multi-directional collection components, gas can be collected from four directions. Two negative pressure components apply negative pressure to the two multi-directional collection pipes, allowing gas to enter from the two inlets on the pipes. Furthermore, since the multi-directional collection pipes are arranged in a Y-shape, gas can be collected from different directions, thereby improving the accuracy of gas monitoring by the monitoring instrument and thus preventing safety accidents.

[0016] Please see Figures 1-4 As shown, this embodiment provides a multi-parameter monitoring device for a closed area in a coal mine, including a monitoring instrument body 100, a multi-directional acquisition component 200 is provided at the middle position of the top side and the middle position of the bottom side of the monitoring instrument body 100, and a negative pressure component 300 is provided at the middle of both sides of the multi-directional acquisition component 200. The two multi-directional acquisition components 200 are connected to the two negative pressure components 300 respectively through the monitoring instrument body 100. Each multi-directional acquisition component 200 includes a circular air inlet pipe 201, which is fixedly connected to the main body 100 of the monitoring instrument. The circular air inlet pipe 201 is connected to the main body 100 of the monitoring instrument. An internally threaded connecting pipe 202 is fixedly connected to the outer side of the circular air inlet pipe 201 near the top. The internally threaded connecting pipe 202 is internally threaded to a multi-directional acquisition pipe 203. The multi-directional acquisition pipe 203 is Y-shaped and has two air inlets. A circular filter plate 204 is fixedly installed at both air inlet ends.

[0017] In practical applications, the two negative pressure components 300 create negative pressure inside the monitoring instrument body 100, allowing gas from the top and bottom of the mine to enter the monitoring instrument body 100 through the two multi-directional sampling pipes 203 for gas detection. To facilitate replacement of the multi-directional sampling pipes 203, a threaded connection 202 is used on the outer side of the circular air inlet pipe 201 to the multi-directional sampling pipe 203. Disassembly of the multi-directional sampling pipe 203 can be achieved simply by rotating it. Simultaneously, the circular filter plates 204 on the two air inlets of the multi-directional sampling pipe 203 filter airborne substances, preventing them from entering the monitoring instrument body 100 and causing damage to its internal components. Please see Figures 1-4 As shown, each negative pressure component 300 includes a circular exhaust pipe 301, which is fixedly connected to the main body 100 of the monitoring instrument and communicates with the main body 100 of the monitoring instrument. A circular mounting pipe 302 is fixedly inserted into the outside of the circular exhaust pipe 301 and communicates with the circular exhaust pipe 301 and the circular mounting pipe 302. A mounting bracket 303 is fixedly connected to the inner wall of the circular mounting pipe 302. A drive motor 304 is fixedly mounted in the middle of one side of the mounting bracket 303. The output shaft of the drive motor 304 passes through the drive motor 304 and is rotatably connected to the mounting bracket 303. A negative pressure fan blade 305 is fixedly sleeved on the end of the output shaft of the drive motor 304.

[0018] In practical applications, negative pressure can be applied to the monitoring instrument body 100 by two negative pressure components 300. The negative pressure fan blades 305 are driven by the drive motor 304 to rotate, drawing out the gas inside the monitoring instrument body 100. Under atmospheric pressure, the gas enters the monitoring instrument body 100 from multiple air inlets. At the same time, the circular exhaust pipe 301 can support the mounting circular pipe 302, and the mounting circular pipe 302 can be pulled out from the circular exhaust pipe 301, making it convenient to clean impurities inside the monitoring instrument body 100.

[0019] Please see Figures 1-2As shown, a rectangular display screen 500 and multiple circular control buttons 600 are provided on one side of the monitoring instrument body 100. The multiple circular control buttons 600 are located at the bottom of the rectangular display screen 500. The rectangular display screen 500 is used to display gas parameters, and the circular control buttons 600 are used to control the monitoring instrument body 100 and set the parameters of the monitoring instrument body 100. Power supply ports 700 are provided on both sides of the monitoring instrument body 100. The two power supply ports 700 are located on the top of the two negative pressure components 300 respectively. The two power supply ports 700 supply power to the monitoring instrument body 100. A mounting plate 800 is fixedly connected to one side of the monitoring instrument body 100. Mounting holes 900 are opened near the edge of one side of the mounting plate 800, and the two mounting holes 900 are symmetrically arranged. The mounting plate 800 is fixed in the mine through the two mounting holes 900.

[0020] In practical applications, the rectangular display screen 500 can display the parameters of the gas in the mine in real time, and the multiple circular control buttons 600 can be used to set the parameters of the monitoring instrument body 100, increasing the operability of the monitoring instrument body 100. The monitoring instrument body 100 can be powered through two power supply ports 700, and the two mounting holes 900 on the mounting plate 800 facilitate the installation of the monitoring instrument body 100.
