[0002] In underground engineering operations such as coal mining, shale gas extraction, and deep tunnel excavation, the gas contained in the strata often bursts out during construction due to pressure release, forming a flammable and explosive mixed gas environment. According to statistics, high-gas mines account for more than 40% of all mines in my country, and gas outburst accidents account for nearly 30% of all coal mine accidents, seriously threatening the safety of personnel and equipment underground. In order to prevent the risk of explosion caused by gas accumulation, the industry generally uses water exploration drilling rigs to conduct pre-drilling and pressure relief operations.

[0003] For example, authorization announcement number CN 207988940 U relates to a coal mine drilling rig support device, belonging to the field of mining equipment technology. It provides a coal mine drilling rig support device with a simple structure, convenient use, small footprint, and easy transportation. The technical solution adopted is as follows: track wheels are installed at the bottom of the vehicle body; support cylinders are installed at the four corners of the bottom of the vehicle body; support cylinders are fixed on both sides of the middle of the vehicle body; a movable sleeve is fitted outside the support cylinder; a top support is installed on the top of the movable sleeve; a support shaft is installed between the movable sleeves; a rotating platform is installed on the support shaft; the rotating platform is rotatably mounted on the support shaft through a bushing; a slide rail is installed on the rotating platform; the drilling rig is slidably mounted on the slide rail; an adjusting cylinder is also installed on the vehicle body; the cylinder body of the adjusting cylinder is hinged to the vehicle body; a connecting lug is provided on the piston rod of the adjusting cylinder; a lug seat and a pin for connecting the lug and the lug seat are provided at the bottom front end of the rotating platform; this utility model is widely used in coal mine drilling rigs.

[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] like Figures 1 to 5 As shown, the present invention provides a novel water exploration drilling rig for gas emission, including a vehicle body 1 and a drilling mechanism 2. The drilling mechanism 2 includes a support plate 21, which is located on the top of the vehicle body 1. A hydraulic motor 22 is fixedly installed on the top of the support plate 21, and a drill rod 23 is fixedly installed on the output end of the hydraulic motor 22.

[0029] An air collection box 3 is fixedly installed on the top of the vehicle body 1. A connecting cover 4 is connected to the left side of the air collection box 3, and an air supply pipe 5 is connected to the rear side of the air collection box 3. Through holes 6 are opened on both sides of the air collection box 3.

[0030] An air pump 12 is fixedly installed on the top of the vehicle body 1. The end of the air supply pipe 5 away from the air collection box 3 is connected to the input end of the air pump 12, and the output end of the air pump 12 is connected to the exhaust pipe 13.

[0031] A support rod 34 is fixedly connected to the inner wall of the connecting cover 4, and the support rod 34 is arranged in a ring array. A fixing plate 35 is fixedly connected to the other end of the support rod 34. A shaft 36 is rotatably connected to the left side of the fixing plate 35 through a bearing. A movable ring 37 is fixedly connected to the surface of the shaft 36. A rubber ring is sleeved on the surface of the movable ring 37. A cleaning brush 38 is fixedly installed on the surface of the shaft 36, and the rubber ring and the cleaning brush 38 are in contact with the surface of the drill rod 23.

[0032] The movable ring 37 is positioned on the outside by the support rod 34 and the fixing plate 35. When the drill rod 23 rotates to drill, the friction between it and the rubber ring can drive the movable ring 37, the shaft 36 and the cleaning brush 38 to rotate at high speed. This allows the cleaning brush 38 to clean the surface of the drill rod 23, reducing the probability of coal mine gravel entering the gas collection box 3, thus achieving the effects of self-cleaning and protection.

[0033] The top of the vehicle body 1 has an opening 9, which is connected to the air collection box 3. A filter screen 10 is fixedly installed on the inner wall of the air collection box 3, and an inclined plate 11 is fixedly connected to the front side of the filter screen 10.

[0034] In addition, a mounting bracket 14 is fixedly connected to the bottom of the vehicle body 1, a sliding plate 15 is fixedly connected to the bottom of the support plate 21, a drive motor 16 is fixedly installed on the right side of the mounting bracket 14, a lead screw 17 is rotatably connected to the left side of the inner wall of the mounting bracket 14 through a bearing, the other end of the lead screw 17 passes through the sliding plate 15 and is fixedly connected to the output end of the drive motor 16, and a groove 18 is opened on the top of the vehicle body 1, and the surface of the sliding plate 15 is slidably connected to the inner wall of the groove 18.

[0035] Rollers 19 are fixedly installed at the four corners of the bottom of the support plate 21, and a groove 20 is provided on the top of the vehicle body 1. The groove 20 is connected to the slide 18.

[0036] When the drive motor 16 starts, causing the lead screw 17 to move the adjusting plate and the support plate 21, the support plate 21 can drive the roller 19 to roll on the bottom of the inner wall of the groove 20, thereby further improving the stability of the movement of the support plate 21 and the hydraulic motor 22.

[0037] Furthermore, a fixing ring 7 is fixedly connected to the left side of the connecting cover 4, and a limiting rod 8 is fixedly connected to the left side of the fixing ring 7. The limiting rod 8 is distributed in a ring array.

[0038] A partition 31 is fixedly connected to the top of the vehicle body 1, and several limiting frames 32 are fixedly connected to the rear side of the partition 31. The air supply pipe 5 is located inside the limiting frame 32.

[0039] A guide cylinder 33 is fixedly connected to the bottom of the vehicle body 1. The guide cylinder 33 is connected to the opening 9. The falling gravel can be piled up in one place by the guide cylinder 33, which is convenient for cleaning.

[0040] The working principle and usage process of this utility model are as follows: When in use, first move the vehicle body 1 into the mine and bring the connecting cover 4 close to the inner wall of the mine. Insert the limiting rod 8 on the surface of the fixing ring 7 into the recess of the inner wall of the mine. Then pull the end of the exhaust pipe 13 away from the air pump 12 out of the mine. Next, start the hydraulic motor 22 and the drive motor 16. The hydraulic motor 22 drives the drill rod 23 to rotate at high speed. At the same time, the output end of the drive motor 16 drives the lead screw 17 to rotate. The lead screw 17 drives the slide plate 15, the support plate 21, the hydraulic motor 22 and the drill rod 23 to move, so that the drill rod 23 drills into the inner wall of the mine. At this time, the gas between the coal seams in the mine can enter the interior of the gas collection box 3 through the connecting cover 4. By starting the air pump 12, the gas in the gas collection box 3 can be discharged to the outside through the gas pipe 5, the air pump 12 and the exhaust pipe 13, thereby avoiding safety accidents caused by excessive gas content inside the mine.

[0041] Meanwhile, during drilling, the friction between the drill rod 23 and the rubber ring can drive the movable ring 37, shaft 36 and cleaning brush 38 to rotate at high speed, thereby enabling the cleaning brush 38 to clean the surface of the drill rod 23. A small amount of gravel enters the interior of the gas collection box 3 through the connecting cover 4 and the through hole 6. At this time, the filter screen 10 can block the gravel to prevent it from entering the gas delivery pipe 5, and the gravel falls to the ground through the inclined plate 11 and the guide cylinder 33 for easy cleaning. The partition plate 31 and the limiting frame 32 can limit the gas delivery pipe 5 to prevent it from getting tangled with other parts and affecting the gas flow.
