[0002] Gas is a colorless, odorless gas that is insoluble in water, does not support combustion, and cannot sustain breathing. When it reaches a certain concentration, it can cause people to suffocate due to lack of oxygen, and can also cause combustion or explosion. Gas usually exists in the coal body or surrounding rock in a free state or adsorbed state. During geological detection and exploration of gas, it is necessary to drill holes in the coal mine with a drilling rig to extract the gas inside.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In the scheme of this application:

[0020] 1. To address the problem of coal dust being easily contained in the gas during gas extraction in the prior art, the present invention provides a first filter, a second filter, a motor, and an impeller.

[0022] 3. By setting the arc plate and limiting the position of the arc plate, the rectangular box can be stabilized. By combining the two arc plates, a ring can be formed. By putting the ring on the surface of the drill bit and rotating the ring, the sponge pad on the arc plate can be used to clean the coal dust on the drill bit surface.

When the drilling is completed and the gas concentration needs to be detected, the multiple protective plates can be removed and combined in a card frame. With the help of the drive of the second motor, the protective plates can be driven to rotate, thereby continuously rubbing the surface of the detection cylinder to achieve the effect of heating the detection cylinder, so that the gas inside the detection cylinder expands due to the heat. Moreover, due to the difference in the thermal expansion coefficient of air and the thermal expansion coefficient of gas, the gas concentration can be measured with the help of the moving distance of the marking rod.

The second motor 605 drives the second gear 607 to rotate, so that the protective plate 703 is constantly rubbed against the detection cylinder 602, causing the surface of the detection cylinder 602 to heat up. When the heat reaches a certain level, the gas inside the detection cylinder 602 will expand, and then squeeze the blocking plate 613 upward to achieve the effect of detecting the gas concentration inside the detection cylinder 602.

[0060] The use process of the gas geological detection and exploration device and method provided by the present invention is as follows:

[0061] Working principle: When the staff is conducting gas detection and exploration, they need to drill the coal seam first. At this time, they can first pull out the baffles 3051 in the rectangular boxes 303 on both sides, take out the first filter 306, and then push the collection frame 502 to the bottom of the drill bit 104 to align the positions of the limit frame 503 and the limit groove 504. Then, the first filter 306 can be passed through the limit frame 503 and the limit groove 504 to achieve the effect of stabilizing the position of the collection frame 502. Then, the second filter can be rotated. The mesh 308 rotates the two second filter screens 308 toward each other, and the racks 312 on the two second filter screens 308 eventually fit together. At this time, the two first filter screens 306 and the two second filter screens 308 together form a concave frame, which covers the top of the drill bit 104. When the drill bit 104 is working, the coal fragments thrown out will be blocked by the concave frame formed by the first filter screens 306 and the second filter screens 308, and the fallen coal fragments will fall into the collection frame 502.

[0062] When gas needs to be extracted, the first filter 306 and the second filter 308 are disassembled and put back into the rectangular box 303. During this process, the second filter 308 can be rotated to a parallel state with the first filter 306 and placed together in the rectangular box 303. At this time, the first filter 306 and the second filter 308 will be wet. After that, the second filter 308 is rotated to a vertical state again. At this time, the block 3032 can be pulled out from the circular hole 3031 and the air duct 206 can be inserted into the circular hole 3031. The hole 3031 is inserted into the hole 3031, and the two arc plates 405 are pushed toward the direction close to the connecting tube 207. The protrusion 404 inside the circular tube 403 slides along the inside of the slide groove 402. The two arc plates 405 are sleeved on the connecting tube 207 to stabilize the position of the rectangular box 303. The sponge pads on the arc plates 405 increase the friction force. When the drill bit 104 drills into the designated position as the driving block 101 moves, the driving block 101 can drive the drill bit 104 to The electric telescopic rod 204 is retracted, and then the electric telescopic rod 204 is started again. The electric telescopic rod 204 drives the drill bit 104 to move forward. At this time, the drill bit 104 and the drill rod 103 are in a separated state. Then the fan 205 can be started. The fan 205 extracts the gas inside the drill hole and blows it to the outside through the air duct 206. Before this, the staff needs to take sealing measures for the drilled hole to prevent gas leakage. At this time, the motor 310 is started to drive the impeller 311 to rotate. The impeller 311 will stir the water inside the rectangular box 303. At this time, there will be splashing water, which will moisten the air inside the rectangular box 303 and continuously moisten the second filter 308. At this time, the gas blown into the rectangular box 303 from the air duct 206 will come into contact with the water mist and pass through the second filter 308. At this time, the coal dust in the gas will be blocked by the second filter 308 and absorbed by the water mist, achieving the effect of dust reduction, ensuring the cleanliness of the gas, and facilitating the detection of the gas concentration;

[0063] When the drill bit 104 is drilling, the slip ring 701 can be moved so that the ring composed of multiple protective plates 703 covers the drill bit 104, thereby achieving the effect of blocking coal dust. When the drilling is completed and the gas concentration needs to be detected, the gas inside the rectangular box 303 will enter the detection cylinder 602 through the conduit 601. After entering, the inside of the conduit 601 can be closed through the valve on the conduit 601. Then the multiple protective plates 703 can be removed, and an appropriate number of protective plates 703 can be selected according to the size of the detection cylinder 602. According to the convex plates and positioning grooves on the protective plates 703, they are spliced ​​together and then placed in the card frame 609. The push rod 611 is pushed to move the card frames 609 on both sides toward each other until the protective plates 703 touch the detection cylinder 602. At this time, the second motor 605 is started. When the first gear 606 is driven to rotate, the second gear 607 will rotate, causing the protective plate 703 to rub against the detection cylinder 602, causing the surface of the detection cylinder 602 to heat up. When the heat reaches a certain level, the temperature sensor 6021 detects it and shuts down the second motor 605. The push rod 611 moves the two clamping frames 609 away from each other, causing the protective plate 703 to separate from the detection cylinder 602, thereby dissipating heat from the detection cylinder 602. The gas inside the detection cylinder 602 expands due to the heat, and then squeezes the blocking plate 613 upward. Since the thermal expansion coefficient of air is smaller than that of gas, the movement distance of the marking rod 614 can be used to detect the gas concentration inside the detection cylinder 602. That is, when the predetermined temperature for gas expansion is reached, the marking rod 614 moves upward, indicating that the gas concentration is relatively pure.

[0064] When the drill bit 104 is not in use and needs to be cleaned, the two arc plates 405 can be removed from the round rod 401, and the two arc plates 405 can be combined together through the tooth plate 406 to form a ring, and the ring can be put on the surface of the drill bit 104. By rotating the ring, the coal dust remaining on the surface of the drill bit 104 can be cleaned through the sponge pad.
