Description

Technical Field

[0001] The present invention relates to the technical field of coal mine shaft drilling, and particularly to a waterproof drill pipe for coal mine shaft drilling. Background Art

[0002] Coal mine shaft drilling is a technology for exploring hidden disaster-causing factors. By using a drilling rig, drill tools, etc., cylindrical holes are drilled underground for geological exploration, gas drainage, water exploration and drainage, etc., which has the advantages of high precision, strong intuitiveness, wide adaptability, etc.

[0003] After retrieval, a Chinese patent with the publication number CN117365341A discloses a waterproof drill pipe for mine shaft drilling, which includes a protective block and a drill pipe. A circular groove is opened on the outer part of the protective block, diversion grooves are symmetrically opened on the outer part of the protective block, diversion pipes are symmetrically installed on the outer part of the protective block, the circular groove and the diversion groove are communicated with each other, the diversion groove and the diversion pipe are communicated with each other, a plurality of water outlet grooves are opened on the outer part of the diversion pipe, a first baffle is installed on the outer part of the diversion pipe, a second baffle is installed on the outer part of the diversion pipe, and a third baffle is installed on the outer part of the diversion pipe. By setting the diversion groove and the diversion pipe, it is convenient to divert the gushing water to both sides, and the diversion pipe and the diversion groove form an angle of sixty degrees. At the same time, by setting the first baffle, the second baffle, the third baffle, the fourth baffle and the water outlet groove on the side wall, the impact force of the water flow can be slowed down, and then the water flow is diverted to the ground to avoid damage to the staff and facilities on both sides. However, when this scheme is actually used, there are still the following deficiencies:

[0004] In the above device, when it is observed that water starts to gush out at the connection, the drill pipe is taken out from the deep part and then effective plugging and waterproof work is carried out. However, considering that coal mine drilling operations often reach a quite deep underground depth, the process of taking out the drill pipe is not only time-consuming but also highly complex. There may be many unforeseen risks and challenges during this period. The long operation delay may lead to the deterioration of the water gushing situation, increasing the pressure and flow rate of groundwater inflow, thus posing a serious threat to the safety of the staff.

[0005] Therefore, it is necessary to design a waterproof drill pipe for coal mine shaft drilling to solve the above problems. Summary of the Invention

[0016] As a preferred technical solution of the present invention, the outer wall of the guide wheel is in contact with the outer wall of the rod body.

[0017] As a preferred technical solution of the present invention, the locking structure includes a connecting rod penetrating through the top surface of the fixing frame, a guiding groove is opened on the bottom surface of the inclined support frame, a guiding block is slidably installed on the inner wall of the guiding groove, the top end of the connecting rod is rotatably connected to the bottom surface of the guiding block, a fixing plate is fixedly installed at one end of the sealing plate located outside the connection sleeve, a bayonet is opened on the top surface of the fixing plate, a communication port communicating with the bayonet is opened on the side surface of the fixing plate, and a limiting insertion plate adapted to the bayonet is fixedly installed at the bottom end of the connecting rod.

[0019] As a preferred technical solution of the present invention, the water storage assembly includes a connecting pipe fixedly installed on the outer wall of the connecting sleeve at a position directly below the through port, and the connecting pipe is communicated with the connecting sleeve. The end of the connecting pipe is provided with a water storage tank through which it passes. The inner wall of the water storage tank at the connection with the connecting pipe is slidably installed with a cover plate through a chute and a slider. Two floating plates are symmetrically and fixedly installed on the side surface of the cover plate, and magnetic sheets are provided on the inner walls of both the cover plate and the water storage tank.

[0020] As a preferred technical solution of the present invention, the transmission assembly includes a transmission screw rod penetrating through the outer wall of the connecting pipe.

Especially when encountering water gushing, through the limit fixation of the guide wheel by the pneumatic telescopic rod, the drill pipe is effectively prevented from continuing to move downward, thereby increasing the safety of the operation;

[0024] 2. By setting the piston plate and the pneumatic telescopic rod, once the water gushing phenomenon occurs, the entire device can quickly respond. The water flow is used to drive the axial flow blade to rotate, thereby driving the gas compression device to work. The gas in the sealing cylinder is pushed into the pneumatic telescopic rod to make it extend. Finally, the waterproof mechanism is triggered. The sealing plate automatically slides to a suitable position under the action of the support spring. The arc-shaped opening at its end tightly clamps on the outer wall of the drill pipe, and the sealing is enhanced through the sealing film, effectively preventing water from gushing out through the connecting sleeve, and realizing a fast and effective waterproof measure;

[0025] 3. By setting up a water storage tank and a cover plate, when water gushing occurs, the water flow will enter the water storage tank, push the floating plate to float up and finally close the connection, and at the same time, the magnetic sheet helps to fix the cover plate to stop the water inflow. During this process, the staff can analyze the water samples collected in the water storage tank to judge the specific situation of the water gushing, providing a scientific basis for subsequent treatment. This design not only helps to prevent potential risks but also aids in decision-making, improving the ability to respond to emergencies. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0037] Refer to Figures 1-9 , a waterproof drill rod for coal mine shaft drilling, including an installation unit and a plugging unit;

[0038] Among them, the installation unit includes a mounting sleeve 11, a connecting sleeve 12 is fixedly installed at the top of the mounting sleeve 11, and a rod body 13 is arranged inside the mounting sleeve 11 and the connecting sleeve 12;

[0039] Among them, the plugging unit includes two through ports 21 symmetrically opened on the outer wall of the connecting sleeve 12. Sealing plates 22 are slidably installed on the inner walls of the two through ports 21. Arc-shaped openings corresponding to the rod body 13 are opened at the opposite ends of the two sealing plates 22. Sealing films 23 are arranged on the inner walls of the two arc-shaped openings. Two brackets 24 are symmetrically and fixedly installed on the outer wall of the connecting sleeve 12. Connecting plates 25 are symmetrically and fixedly installed at one end of the two sealing plates 22 located outside the connecting sleeve 12. A first support spring 26 is fixedly installed between the opposite sides of the connecting plate 25 and the bracket 24;

[0040] First, the mounting sleeve 11 can be inserted into the inner side of the opening of the drilling hole and fixed by pouring concrete or other methods. Under the driving action of the drilling rig equipment, the rod body 13 can move inside the mounting sleeve 11 and the connecting sleeve 12 toward the inside of the drilling hole for drilling. After the sealing plate 22 is released from the limit, it can slide along the through port 21 toward the inside of the connecting sleeve 12 under the action of the first support spring 26. The two sealing plates 22 slide synchronously. The arc-shaped openings at their ends can be clamped on the outer wall of the rod body 13, and the bottom surface can plug the connecting sleeve 12. Moreover, the sealing film 23 in the arc-shaped opening can increase the sealing performance between the sealing plate 22 and the rod body 13, preventing water from gushing out through the connecting sleeve 12 and achieving the waterproof effect.

[0041] On the outer wall of the connecting sleeve 12, two groups of guiding components are symmetrically arranged. The guiding component includes a fixing frame 31 fixedly installed on the outer wall of the connecting sleeve 12 at a position directly above the through port 21. The end of the fixing frame 31 is rotatably installed with an inclined support frame 32. The end of the inclined support frame 32 is fixedly installed with two fixing plates 33. A guide wheel 34 adapted to the rod body 13 is rotatably installed between the opposite sides of the two fixing plates 33. The outer wall of the guide wheel 34 is in contact with the outer wall of the rod body 13. A second support spring 35 is fixedly installed between the bottom surface of the inclined support frame 32 and the top surface of the fixing frame 31;

[0042] During the drilling process, the two guide wheels 34 on both sides of the connecting sleeve 12 can guide the rod body 13. Under the action of the second support spring 35, the inclined support frame 32 can have a pulling force towards the rod body 13, ensuring that the guide wheel 34 is always in contact with the outer wall of the rod body 13, playing a guiding role for the rod body 13 and making the descent of the rod body 13 more stable. After the guide wheel 34 is fixed, as the rod body 13 continues to descend, the rod body 13 can drive the guide wheel 34, the fixing plate 33, and the inclined support frame 32 to rotate towards the direction close to the fixing frame 31 through the friction force with the guide wheel 34. When the inclined support frame 32 rotates, the guide wheel 34 can clamp the rod body 13, and finally the rod body 13 is fixed and will not continue to move downward.

[0043] A locking structure is arranged between the guiding component and the sealing plate 22. The locking structure includes a connecting rod 41 penetrating through the top surface of the fixing frame 31. A guiding groove 42 is opened on the bottom surface of the inclined support frame 32. A guiding block 43 is slidably installed on the inner wall of the guiding groove 42. The top end of the connecting rod 41 is rotatably connected to the bottom surface of the guiding block 43. One end of the sealing plate 22 located outside the connecting sleeve 12 is fixedly installed with a fixing plate 44. A bayonet 45 is opened on the top surface of the fixing plate 44. A communication port 46 communicating with the bayonet 45 is opened on the side surface of the fixing plate 44. The bayonet 45 and the communication port 46 are vertically arranged. The diameter of the connecting rod 41 is at least smaller than the width of the communication port 46. A limiting insertion plate 47 adapted to the bayonet 45 is fixedly installed at the bottom end of the connecting rod 41;

[0044] When the inclined support frame 32 rotates, it can drive the connecting rod 41 to move downward through the guiding groove 42 and the guiding block 43. When the connecting rod 41 moves downward, it can drive the limiting insertion plate 47 at the bottom end to move out of the bayonet 45 on the fixing plate 44, thus releasing the limit on the sealing plate 22.

[0045] Two groups of water storage components are symmetrically arranged on the outer wall of the connecting sleeve 12. The water storage components include a connecting pipe 51 fixedly installed at a position directly below the through port 21 on the outer wall of the connecting sleeve 12, and the connecting pipe 51 is communicated with the connecting sleeve 12. A water storage tank 52 is penetrated through the end of the connecting pipe 51. The inner wall of the water storage tank 52 at the communication position with the connecting pipe 51 is slidably installed with a cover plate 53 through a chute and a slider. Two floating plates 54 are symmetrically and fixedly installed on the side surface of the cover plate 53. Magnetic sheets 55 are arranged on the inner walls of both the cover plate 53 and the water storage tank 52. Four corners of the bottom surface of the water storage tank 52 are fixedly installed with tapered rods 56;

[0046] When water enters the water storage tank 52 through the connecting pipe 51, as the water enters the water storage tank 52, under the action of buoyancy, the floating plate 54 can move upward together with the liquid level. When the floating plate 54 moves upward, it can drive the cover plate 53 to move upward through the chute and the slider. When the liquid level rises to the highest point, at this time, the cover plate 53 can block the communication position between the connecting pipe 51 and the water storage tank 52, and under the action of the two magnetic sheets 55, the cover plate 53 can be fixed, and water will no longer enter the water storage tank 52. When the staff checks, the water in the water storage tank 52 can be analyzed to judge the water quality of the gushing water.

[0047] Drive components are arranged on both groups of water storage components. The drive components include a drive screw rod 61 penetrated through the outer wall of the connecting pipe 51. One end of the drive screw rod 61 located inside the connecting pipe 51 is fixedly installed with an axial flow blade 62. A sealing cylinder 63 is fixedly installed on the outer wall of the connecting pipe 51, and the end of the drive screw rod 61 is located inside the sealing cylinder 63. A piston plate 64 is slidably installed on the inner wall of the sealing cylinder 63, and the piston plate 64 is screwed with the drive screw rod 61. An air pipe 65 is penetrated through the end of the sealing cylinder 63. A support rod 66 is fixedly installed at the top end of the inclined support frame 32, and an air cylinder 67 is fixedly installed at the end of the support rod 66. The air pipe 65 and the air cylinder 67 are communicated through a conduit 69. A plurality of pin slots 68 corresponding to the air cylinder 67 are arranged in an annular array on the side surface of the guide wheel 34. An opening corresponding to the telescopic end of the air cylinder 67 is arranged on the side surface of the fixed disk 33;

[0048] If water gushes out during the drilling process, the gushing water can first enter the water storage tank 52 through the connecting pipe 51. When the water passes through the connecting pipe 51, it can impact the axial flow blades 62. When the axial flow blades 62 are impacted, they can rotate and drive the transmission screw 61 to rotate. The piston plate 64 is slidably connected to the sealing cylinder 63 and is screwed to the transmission screw 61. Therefore, when the transmission screw 61 rotates, it can drive the piston plate 64 to slide along the inner wall of the sealing cylinder 63, thereby pushing the gas in the sealing cylinder 63 into the pneumatic telescopic rod 67 through the air pipe 65 and the conduit 69. When the piston plate 64 slides to the end of the transmission screw 61 and abuts against the inner wall of the sealing cylinder 63, the piston plate 64 can no longer move, and the axial flow blades 62 stop rotating. When the gas in the sealing cylinder 63 enters the pneumatic telescopic rod 67 through the air pipe 65 and the conduit 69, the pneumatic telescopic rod 67 can extend, and the telescopic end can pass through the opening and enter the pin slot 68 on the side of the guide wheel 34. If the telescopic end contacts the side of the guide wheel 34 but does not enter the pin slot 68 when the pneumatic telescopic rod 67 extends, under the rotation of the guide wheel 34, the telescopic end can still enter the pin slot 68 eventually to realize the limit fixation of the guide wheel 34.

[0049] The specific working principle of the present invention is as follows:

[0050] In use, first, the installation sleeve 11 can be inserted into the inner side of the opening of the drilling hole and fixed by pouring concrete or other methods. At the same time, the taper rod 56 at the bottom of the water storage tank 52 is inserted into the ground to reinforce the whole. Under the driving action of the drilling rig equipment, the rod body 13 can move inside the installation sleeve 11 and the connecting sleeve 12 towards the inside of the drilling hole for drilling. During the drilling process, the two guide wheels 34 on both sides of the connecting sleeve 12 can guide the rod body 13. Under the action of the second support spring 35, the inclined support frame 32 can have a pulling force towards the rod body 13, ensuring that the guide wheels 34 always fit against the outer wall of the rod body 13, playing a guiding role for the rod body 13 and making the descent of the rod body 13 more stable. If water gushes out during the drilling process, the gushing water can first enter the water storage tank 52 through the connecting pipe 51. When the water passes through the connecting pipe 51, it can impact the axial flow blades 62. When the axial flow blades 62 are impacted, they can rotate and drive the transmission screw 61 to rotate. The piston plate 64 is slidably connected to the sealing cylinder 63 and is screwed to the transmission screw 61. Therefore, when the transmission screw 61 rotates, it can drive the piston plate 64 to slide along the inner wall of the sealing cylinder 63, thereby pushing the gas in the sealing cylinder 63 into the pneumatic telescopic rod 67 through the air pipe 65 and the conduit 69. When the piston plate 64 slides to the end of the transmission screw 61 and abuts against the inner wall of the sealing cylinder 63, the piston plate 64 can no longer move, and the axial flow blades 62 stop rotating.

[0051] When the gas in the sealing cylinder 63 enters the pneumatic telescopic rod 67 through the trachea 65 and the conduit 69, the pneumatic telescopic rod 67 can extend, and the telescopic end can pass through the opening and enter the pin slot 68 on the side of the guide wheel 34. If the telescopic end contacts the side of the guide wheel 34 but does not enter the pin slot 68 when the pneumatic telescopic rod 67 extends, at this time, under the rotation of the guide wheel 34, the telescopic end can still finally enter the pin slot 68 to realize the limit fixation of the guide wheel 34; after the guide wheel 34 is fixed, as the rod body 13 continues to descend, the rod body 13 can drive the guide wheel 34, the fixed disk 33, and the diagonal support 32 to rotate towards the fixed frame 31 through the friction with the guide wheel 34. When the diagonal support 32 rotates, the guide wheel 34 can clamp the rod body 13, and finally the rod body 13 is fixed and will not continue to move downward. When the diagonal support 32 rotates, it can drive the connecting rod 41 to move downward through the guide groove 42 and the guide block 43. When the connecting rod 41 moves downward, it can drive the limit insertion plate 47 at the bottom to move out of the bayonet 45 on the fixed plate 44, thus releasing the limit on the sealing plate 22. After the sealing plate 22 is released from the limit, it can slide along the through port 21 towards the inside of the connecting sleeve 12 under the action of the first support spring 26. And the communication port 46 on the fixed plate 44 can drive the two sealing plates 22 to slide synchronously through the connecting rod 41. The arc-shaped ports at their ends can be clamped on the outer wall of the rod body 13, and the bottom surface can block the connecting sleeve 12. And the sealing film 23 in the arc-shaped port can increase the sealing performance between the sealing plate 22 and the rod body 13, avoiding water from gushing out through the connecting sleeve 12 and achieving the waterproof effect.

[0052] When water enters the water storage tank 52 through the connecting pipe 51, as the water enters the water storage tank 52, the floating plate 54 can move upward together with the liquid level under the action of buoyancy. And when the floating plate 54 moves upward, it can drive the cover plate 53 to move upward through the chute and the slider. When the liquid level rises to the highest point, at this time, the cover plate 53 can block the connection between the connecting pipe 51 and the water storage tank 52, and the cover plate 53 can be fixed under the action of the two magnetic pieces 55, and water will no longer enter the water storage tank 52. When the staff checks, they can analyze the water in the water storage tank 52 to judge the water quality of the gushing water.

[0053] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
