Description

Technical Field

[0001] The present invention relates to the technical field of safe production in coal mines, and in particular to intelligent monitoring equipment for safe production in coal mines. Background Art

[0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. During coal mining, it is necessary to monitor the production environment for safe production. The Chinese patent application number 202410122018.2 discloses "a monitoring device for coal mine safety production, including an outer shield, an inner shield, a camera, a frame and a plurality of mining gas sensors. A circular plate is sleeved in the frame. The edge of the outer shield is fixedly connected to the lower end of the circular plate by bolts. A window is opened on one side of the outer shield, and a fixed inner side of the outer shield is provided with a camera. An annular plate is connected, the inner shield is sleeved in the annular plate and forms a cavity with the outer shield, and a gas distribution mechanism is arranged in the cavity, the gas distribution mechanism is composed of a first bend pipe, a second bend pipe, a bend plate and a third bend pipe, and the gas distribution mechanism divides the cavity into multiple chambers, so that the airflow cleans the surface of the inner shield when flowing in the multiple chambers. The monitoring method and device for safe production in coal mines can enable the monitoring equipment to work efficiently to obtain images of the mining site, and can realize automatic cleaning work, and can also cyclically detect the air quality and abnormal vibration underground";

[0003] This technical solution only solves the problem that the monitoring device is easily contaminated by coal dust underground, affecting the quality of the monitoring image, and the air fluidity underground is poor, and the accuracy of gas detection is also low. However, whether mining operations are carried out in underground coal mines or open-pit coal mines, a large amount of dust will be generated. Construction workers carry out mining operations in dusty environments for a long time, which can easily cause the workers to inhale a large amount of coal dust. Moreover, when the existing intelligent monitoring equipment monitors the gas in the environment, it is often monitored through gas sensors that contact the air. However, after the sensor has been in contact with air containing coal dust for a long time, the coal dust is easy to adhere to and accumulate on the sensor, which can easily cause the sensor to be unable to effectively contact the air, thereby affecting the sensor's monitoring effect.

[0021] 2. The present invention sprays the gas discharged from the vacuum cylinder toward the back side of the dust-proof and breathable membrane through the jet hole, so that the coal dust on the dust-proof and breathable membrane is sprayed off, and then water is sprayed toward the dust-proof and breathable membrane through the water spray pipe. The coal dust on the dust-proof and breathable membrane is washed down by the dual effects of the sprayed water and gas, so that the coal dust falls into the cleaning box with the water, and is filtered by the filter layer and then pumped into the water tank through the first water pumping pipe, thereby realizing water recycling. The dust-proof and breathable membrane that has been showered with water is dried by the wind force of the heat dissipation fan and the heat of the intelligent monitoring host, so that the dust-proof and breathable membrane maintains a strong dust-proof ability.

The end of the first water pumping pipe 907 close to the air collecting bucket 301 is fixedly installed in the cleaning box 901 by insertion and is located below the filter layer. The end of the first water pumping pipe 907 away from the air collecting bucket 301 is fixedly installed in the water tank 902 by insertion, and the bottom end of the second water pumping pipe 908 is fixedly installed in the support plate 807 by insertion.

[0046] Working principle: When the present invention is in use, the dual-axis motor 808 is started, and the dual-axis motor 808 drives the second gear 809 to rotate, and the second gear 809 drives the gear ring 309 to rotate, so that the reciprocating wheel 308 rotates accordingly. When the reciprocating wheel 308 rotates, the connecting rod 310 drives the reciprocating plate 306 to reciprocate between the vacuum cylinder 303 and the vertical plate 511. When the reciprocating plate 306 moves toward the vertical plate 511, the reciprocating rod 305 drives the piston 304 to move in the vacuum cylinder 303, and the vacuum cylinder 303 is used to extract air;

[0047] When the reciprocating plate 306 moves toward the vertical plate 511, the limiting action of the limiting groove 501 makes the rotating baffle 502 keep vertical when in contact with the follower plate on the sliding plate 407, so that the rotating baffle 502 drives the sliding plate 407 to move at the same time through the follower plate. At this time, the rack 406 is driven to move through the sliding plate 407, and the first gear 405 is driven to rotate through the rack 406. When the first gear 405 rotates, the air intake plate 402 is driven to the exhaust plate through the plate shaft 404. The cylinder 303 rotates in the direction of rotation, so that the air inlet plate 402 changes from a vertical state to a horizontal state, so that the top of the air outlet hopper 403 is covered, so that the air collecting box 302 is in an open state. At this time, the air is extracted through the air pump 303, so that the gas from the external environment of the device passes through the lower mesh plate 802 and then passes through the dust-proof breathable membrane 806 to block the coal dust and enter the air collecting hopper 301. At this time, the dust-free gas is detected by the gas sensor 7 to avoid a large amount of coal dust adhering to the surface of the gas sensor 7 after long-term use;

[0048] When the reciprocating plate 306 moves to contact with the vertical plate 511, the second spring 509 is compressed by the sliding plate 407. At this time, the top plate 512 is inserted into the movable groove 504, and the trigger plate 506 is driven to rotate through the top plate 512, and the rotating baffle 502 is driven to rotate at the same time through the synchronous shaft 503. When the rotating baffle 502 rotates to the horizontal, the accompanying plate and the rotating baffle 502 are no longer in contact. Under the elastic force of the second spring 509, the rack 406 is driven to reset through the sliding plate 407, and the first gear 405 is driven to rotate through the rack 406, so that the air intake plate 402 is restored from the horizontal state to the vertical state, so that the air outlet hopper 403 is in an open state, and the air collecting box 302 is in a closed state.

[0049] When the trigger plate 506 rotates under the contact with the top plate 512, the first spring 507 is stretched. When the following plate on the sliding plate 407 leaves the reciprocating plate 306, the rotating baffle 502 is restored from the horizontal state to the vertical state under the pulling force of the first spring 507.

[0050] When the reciprocating plate 306 moves toward the direction close to the air pump 303, the rotating baffle 502 contacts the accompanying plate on the sliding plate 407 again, and the accompanying plate squeezes the rotating baffle 502, driving the rotating baffle 502 to rotate first, so that the reciprocating plate 306 moves between the accompanying plate and the air pump 303, and then resets by the pulling force of the first spring 507. In this process, the piston 304 is driven by the reciprocating rod 305 to move toward the gas collecting box 302, so that the gas in the air pump 303 and the gas collecting box 302 is discharged into the gas outlet 403.

[0051] When the dual-axis motor 808 is started, the upper movable roller 804 is driven to rotate through the transmission belt 811, and the lower movable roller 805 is driven to rotate in the opposite direction with the upper movable roller 804 through the two transmission belts 811, and the dust-proof breathable membrane 806 is clamped by the upper movable roller 804 and the lower movable roller 805, and then the dust-proof breathable membrane 806 is driven to move, so that the dust-proof breathable membrane 806 is continuously rotated inside the device housing 1;

[0052] The dust-proof breathable membrane 806 blocks the coal dust from entering the device from the upper plate 801 and the lower plate 802. After the dust-proof breathable membrane 806 carrying the coal dust rotates into the cleaning box 901, the gas discharged from the gas outlet 403 is introduced into the gas injection hopper 905 through the gas outlet pipe 904, and then the gas is sprayed to the back of the dust-proof surface of the dust-proof breathable membrane 806 through the gas injection hole 906, so that the coal dust on the dust-proof surface is sprayed off. In addition, by starting the micro water pump 903, the second water pump 90 8 After the water in the water tank 902 is pumped into the micro water pump 903, it is discharged through the water outlet pipe 909, and then the water in the water outlet pipe 909 is sprayed out through the water spray pipe 910, and the water is sprayed toward the dust-proof breathable membrane 806 through the water spray pipe 910. Under the dual effects of the sprayed water and gas, the coal dust on the dust-proof breathable membrane 806 is washed down, so that the coal dust falls into the cleaning box 901 with the water, and after being filtered by the filter layer, it is pumped into the water tank 902 through the first pumping pipe 907, thereby realizing water recycling;

[0053] When the intelligent monitoring host 6 is started to monitor coal mine production safety, the cooling fan 813 is started at the same time. The heat of the intelligent monitoring host 6 is discharged from the device through the cooling mesh plate 812 through the cooling fan 813. In this process, the dust-proof and breathable membrane 806 that has been showered with water is dried by the wind force of the cooling fan 813 and the heat of the intelligent monitoring host 6, so that the dust-proof and breathable membrane 806 maintains a strong dust-proof ability.
