Description

Technical Field

[0001] The present invention relates to the technical field of environmental monitoring, and in particular to a mine atmospheric environment monitoring device and a monitoring method. Background Art

[0002] Mines are the main places for mining operations, including excavation bodies, transportation channels and auxiliary facilities formed by mining. Mines with excavation bodies exposed on the surface are called open-pit mines; mines with excavation bodies underground are called underground mines. Most mines also include ore dressing plants. Mines generate a lot of dust during the mining process, which pollutes the environment of the mine and affects the health of the workers. In order to reduce the harm of mine atmosphere to workers, it is necessary to use atmospheric environment monitoring equipment for monitoring. It is a process of intermittently or continuously observing, measuring, and analyzing the changes and environmental impact of one or more environmental factors or indicators according to a pre-designed time and space, using comparable environmental information and data collection methods for a specific purpose. For example, the existing public document CN114965875B-A portable multi-directional atmospheric environment monitoring device discloses a device for monitoring the atmospheric environment; Although the existing publicly available mine atmospheric environment monitoring equipment can realize automatic filling of injection liquid, there are still certain shortcomings in actual use: first, the existing atmospheric environment monitoring device detects air through a single detection device or uses multiple detection devices in the same chamber when in use, and the air drawn in in this way will fill the entire detection chamber, and dust will adhere to the surface of the monitoring equipment for a long time, affecting the monitoring data. At the same time, it is impossible to perform comparative detection of air samples, affecting the monitoring accuracy; secondly, the existing atmospheric environment monitoring device uses a single driving device to drive the impeller to rotate and extract external environmental air for detection when in use, and this method cannot adjust the air intake volume and air intake speed according to the pollution degree of the surrounding atmospheric environment when the air intake duct rotates, which may affect the accuracy and scope of application of subsequent multi-sample comparative detection; finally, the existing atmospheric environment monitoring device adsorbs chemical substances in the atmosphere through the adsorption liquid inside the chassis when in use, and this method can only suck the air in a single monitoring area into the adsorption liquid when monitoring the device. If sampling and detection are performed on multiple areas, the adsorption liquid needs to be continuously replaced, which will increase the workload and low efficiency; therefore, it is necessary to improve the existing technology to solve the above technical problems.

[0043] For details, please refer to Figure 7 and Figure 8A hanging frame 203a is installed on the inner wall of the air distribution duct 203, and a second electromagnetic block 204 is installed at the bottom center of the hanging frame 203a; a first partition plate 301a is fixedly connected to the inner wall of the docking tube 301, and a hollow tube 306 is slidably connected to the inner center of the first partition plate 301a, and a moving plate 304 is installed on the top of the hollow tube 306, and a limiting ring 305 is installed on the bottom end of the hollow tube 306. The first telescopic rod 307 is installed at the four corners of the upper surface of the limiting ring 305, and the outer wall of the first telescopic rod 307 is sleeved with a first spring 3 08; wherein, a first iron sheet 304a is embedded in the center of the upper surface of the movable plate 304, and air holes 306a are evenly spaced at the top of the outer wall of the hollow tube 306 along its circumferential direction, and the top of the first telescopic rod 307 is installed at the bottom of the first partition 301a, and the first spring 308 is located between the first partition 301a and the limit ring 305, and the movable plate 304 is located directly above the first partition 301a, and the top of the docking tube 301 is disassembled and docked inside the air distribution pipe 203, and the first iron sheet 304a is magnetically attracted to the second electromagnetic block 204; When the above arrangement is used, the chassis 100 is pushed to the position where the atmospheric environment needs to be monitored in the mine, and then the driving device 102 is started. The driving device 102 drives the top cover 101 to rotate along the top of the chassis 100. During the rotation process, the visibility detection mechanism 104b on the top cover 101 is driven to rotate, so that air visibility detection and insect and bird repelling operations can be realized.

The rings 105 are magnetically attracted to each other; the rings 105 also include a speed regulating assembly 500 disposed inside the ring frame 105, the speed regulating assembly 500 includes a first gear ring 501, a second gear ring 502 and a third gear ring 503 which are sequentially disposed inside the ring frame 105 from outside to inside, and second telescopic rods 504 are installed at the four corners at the bottom of the first gear ring 501, the second gear ring 502 and the third gear ring 503, and a second spring 505 is sleeved on the outer wall of the second telescopic rod 504; the bottom end of the second telescopic rod 504 is installed at the inner bottom end of the ring frame 105, and a plurality of second springs 505 are respectively located between the ring frame 105 and the first gear ring 501, the second gear ring 502 and the third gear ring 503, and the first gear ring 501, the second gear ring 502 and the third gear ring 503 are magnetically attracted to the upper and lower corresponding first electromagnetic blocks 105b; When the above arrangement is in use, the driving device 102 is used to drive the top cover 101 and the visibility detection mechanism 104b inside it and the built-in frame 104c, the bevel gear 104f, etc. in the air inlet duct 104 to rotate synchronously with the central axis of the top cover 101, and the rack on the outer wall of the bevel gear 104f is meshed with the rack on the surface of the first gear ring 501 below, so when the bevel gear 104f rotates with the central axis of the top cover 101, it will be driven to rotate independently under the action of the first gear ring 501, and the rotation of the bevel gear 104f will drive the impeller 104e to rotate through the fan shaft 104d, thereby drawing the mine atmosphere into the chassis 100, wherein the inner side of the first gear ring 501 is sequentially provided with the first gear ring 501 and the second .... The second gear ring 502 and the third gear ring 503, and the corresponding first electromagnetic blocks 105b are respectively arranged below the first gear ring 501, the second gear ring 502 and the third gear ring 503. At this time, the first electromagnetic block 105b corresponding to the lower part of the first gear ring 501 is energized, and the first electromagnetic block 105b corresponding to the lower part of the second gear ring 502 or the third gear ring 503 is stopped.

At the same time, the third electromagnetic block 40 2b is powered on, and magnetic attraction is generated between the third electromagnetic block 402b and the magnetic plates 405 on the sliding blocks 404 on both sides, so that the sliding block 404 slides along the inner wall of the installation frame 402 to adjust its position. During this process, the magnetic plate 405 is adsorbed on the second iron sheet 403a on the corresponding adjustment block 403, so when the sliding block 404 moves, the position of the adjustment block 403 will be adjusted under the action of the magnetic plate 405 and the second iron sheet 403a, so that the adjustment block 403 is inserted into the air inlet duct 104, so as to achieve the purpose of changing the diameter of a part of the air inlet duct 104, and then the air intake volume in the same time period can be changed, so as to adjust the air intake volume and air intake speed according to the pollution degree of the surrounding atmospheric environment, and the application range is wide.

[0049] Furthermore, the sleeve frame 401 is adjusted on the outer wall of the air inlet duct 104, and a through hole is opened on the outer wall of the air inlet duct 104 at the sleeve joint, so that the adjustment block 403 can slide and adjust the position.
