For those of ordinary skill in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0036] As shown in Figures 1 to 5 The controllable shock wave construction system suitable for uphole drilling provided by the embodiments of the present application comprises a shock wave generator 2, a water storage tank 1, a push rod 3, and a high-voltage direct-current power supply control cabinet 5.

[0037] The shock wave generator 2 comprises an electrode holder 21, a negative electrode mounting bracket 22, a positive electrode mounting bracket 23, a metal wire 24, a cable 25, an expansion part 6, and a water injection pipe 26.

[0038] The shock wave generator 2 is clamped in the drill hole 7 by the expansion part 6, which is arranged at the rear of the electrode base 21.

[0039] The negative electrode mounting bracket 22 and the positive electrode mounting bracket 23 are both mounted at the front end of the electrode base 21, and the two ends of the metal wire 24 are connected to the clamping part 8 of the positive electrode mounting bracket 23 and the clamping part 8 of the negative electrode mounting bracket 22 respectively. The input end of the negative electrode mounting bracket 22 and the input end of the positive electrode mounting bracket 23 are electrically connected to the output end of the cable 25 respectively, and the input end of the cable 25 passes through the hole in the center of the electrode base 21 and the channel 91 in the center of the expansion part 6, and then extends out of the drill hole 7 to be electrically connected to the output end of the high-voltage direct-current power supply control cabinet 5.

[0040] The water outlet of the water injection pipe 26 is arranged at the front end of the electrode base 21, the water inlet of the water injection pipe 26 passes through the hole in the center of the electrode base 21 and the channel 91 in the center of the expansion part 6, and then extends out of the drill hole 7 to be connected to the water outlet of the water pump, the water inlet of the water pump is connected to the water outlet of the water storage tank 1, and the water storage tank 1 stores water 15.

[0041] The front end of the push rod 3 is connected to the rear end of the expansion part 6, and the rear end of the push rod 3 extends out of the drill hole 7 to be connected to the pushing mechanism 4.

[0042] It should be noted that the cable 25 and the water injection pipe 26 both pass through the hole in the center of the push rod 3, and the push rod 3 can protect the cable 25 and the water injection pipe 26. The signal transmission cable of the expansion part 6 is also arranged in the hole in the center of the push rod 3. The negative electrode mounting bracket 22 is mounted at the front end of the electrode base 21 by an insulator.

[0043] The pushing mechanism 4 pushes the shock wave generator 2 to a set position in the drill hole 7 through the pushing rod 3, after being pushed to the position, the control of the expanding part 6 makes the outer diameter larger, so that the shock wave generator 2 is clamped in the drill hole 7 through the expanding part 6, then the water pump controls to inject the water 15 in the water storage tank 1 into the drill hole 7 through the water injection pipe 26, the water 15 flows out from the water outlet on the electrode base 21, until the water 15 is 200mm higher than the top of the metal wire 24. The high-voltage direct-current power supply control cabinet 5 loads the high-voltage direct current to the metal wire 24 through the cable 25, the negative electrode installation support 22 and the positive electrode installation support 23, so that the metal wire 24 is electrically exploded to form a shock wave, and the shock wave makes the rock mass broken. The outer wall of the expanding part 6 and the inner wall of the drill hole 7 abut, which can play a certain sealing effect, slow down the rate of water 15 flowing out from the gap between the outer wall of the expanding part 6 and the inner wall of the drill hole 7, and the water 15 is 200mm higher than the top of the metal wire 24, so that the metal wire 24 is still immersed in the water 15 before the completion of the shock wave operation, thereby ensuring the smooth progress of the shock wave operation. The expanding part 6 can fix the position of the shock wave generator 2 well, prevent the shock wave generator 2 from being impacted and flying out of the drill hole 7 by the force of the shock wave, and reduce the pressure applied to the pushing rod 3, while also reducing the energy loss generated by the shock wave generator 2 in the discharge moment, thereby improving the operation efficiency and safety. By setting the expanding part 6 with the sealing effect, the hole device in the traditional operation can also be replaced, the shock wave generator 2 is pushed to the position and then a small amount of water 15 is injected to implement the shock wave operation, which avoids the problem that the operation point to the hole needs to be filled with water 15 to implement the shock wave operation in the prior art, thereby further improving the operation efficiency, and the system has good operation effect, high safety and strong practicability, and is convenient to popularize and use.

[0044] The shock wave generator 2 can be provided with a drainage pipe with the same structure as the water injection pipe 26 for drainage, or the expanding part 6 can be directly contracted for drainage.

[0045] In the embodiment, the expanding part 6 includes a rubber sleeve 61, the rubber sleeve 61 is made of elastic material, and the outer wall of the rubber sleeve 61 abuts against the inner wall of the drill hole 7.

[0046] It should be noted that when the shock wave generator 2 is clamped in the drill hole 7 through the expanding part 6, the rubber sleeve 61 is compressed, and the rubber sleeve 61 can improve the sealing between the outer wall of the expanding part 6 and the inner wall of the drill hole 7, thereby further slowing down the rate of water 15 flowing out from the gap between the outer wall of the expanding part 6 and the inner wall of the drill hole 7, so that the metal wire 24 is still immersed in the water 15 before the completion of the shock wave operation, thereby ensuring the smooth progress of the shock wave operation.

[0047] In the embodiment, the outer wall of the rubber sleeve 61 is provided with a plurality of ring grooves 62, and the plurality of ring grooves 62 are arranged at intervals along the length direction of the rubber sleeve 61.

[0048] It should be noted that the plurality of annular grooves 62 of the outer wall of the rubber sleeve 61 can improve the friction with the inner wall of the drill hole 7, thereby further fixing the position of the shock wave generator 2, preventing the shock wave from forcing the mechanism to fly out of the drill hole 7. At the same time, the sealing between the outer wall of the expansion part 6 and the inner wall of the drill hole 7 can be further improved.

[0049] In this embodiment, the expansion part 6 further comprises a hollow hydraulic cylinder 63, a first taper sleeve 64, a second taper sleeve 65, and an expansion block 66. The hollow hydraulic cylinder 63 comprises a cylinder body 10, a hollow pipe 9, a piston rod 11, and a piston 12.

[0050] The cylinder body 10 is annular in structure, and the piston rod 11 is cylindrical in structure with both ends open. The first taper sleeve 64, the second taper sleeve 65, the cylinder body 10, and the piston rod 11 are all sleeved on the hollow pipe 9. The rear end of the piston rod 11 extends into the cylinder body 10 and is connected to the piston 12. The center of the hollow pipe 9 is a passage 91.

[0051] The front end of the hollow pipe 9 is connected to the rear part of the electrode holder 21. The front end of the first taper sleeve 64 abuts against the rear end of the electrode holder 21, and the rear end of the second taper sleeve 65 abuts against the front end of the piston rod 11. The first taper sleeve 64 and the second taper sleeve 65 are both frustoconical in shape. The small end of the first taper sleeve 64 is oppositely arranged with the small end of the second taper sleeve 65.

[0052] The number of expansion blocks 66 is two or more. The two or more expansion blocks 66 are arranged in the circumferential direction of the hollow pipe 9 and are located between the first taper sleeve 64 and the second taper sleeve 65. The inner walls of both ends of the expansion block 66 are respectively provided with a pushing surface 67 matched with the inclined surface of the first taper sleeve 64 and the inclined surface of the second taper sleeve 65.

[0053] The rubber sleeve 61 is sleeved on the outside of the two or more expansion blocks 66.

[0054] The cylinder body 10 drives the piston rod 11 to move on the hollow pipe 9, so that the first taper sleeve 64 and the second taper sleeve 65 are close to each other. The first taper sleeve 64 and the second taper sleeve 65 push the expansion block 66 to move along the radial direction of the hollow pipe 9 through the pushing surface 67.

[0055] It should be noted that the oil pump assembly of the hollow hydraulic cylinder 63 is arranged on the ground, and two oil ports are arranged on both sides of the cylinder body 10. The hollow hydraulic cylinder 63 can meet the use requirements of the cable 25 arranged by the present application. The expansion part 6 can also adopt a structure of an air bag. In actual application, the electrode holder 21 and the hollow pipe 9 are the current conducting part of the positive electrode mounting bracket; the rear end of the hollow pipe 9 is provided with a wire nose connected with the cable 25. The front end of the electrode holder 21 and the hollow pipe 9 are connected by threads. The rear end of the hollow pipe 9 is provided with a compression joint for protecting the cable 25 and a push rod connecting part.

[0056] When the expansion part 6 is in operation, the hollow hydraulic cylinder 63 is driven to move the piston rod 11 forward on the hollow pipe 9, in the process, the first taper sleeve 64 and the second taper sleeve 65 gradually approach, the inclined surface of the first taper sleeve 64 and the inclined surface of the second taper sleeve 65 push the abutting surface 67 at both ends of the expansion block 66, so that the expansion block 66 moves along the radial direction of the hollow pipe, and the two or more expansion blocks 66 move simultaneously, so that the outer diameter of the two or more expansion blocks 66 increases as a whole, and then drives the rubber sleeve 61 to expand, until the outer wall of the rubber sleeve 61 abuts against the inner wall of the drill hole 7, and finally the shock wave generator 2 is clamped in the drill hole 7. After the shock wave operation is completed, the piston rod 11 is controlled to move backward on the hollow pipe 9, and the plurality of expansion blocks 66 can restore to the initial state under the action of the elasticity of the rubber sleeve 61. The hollow hydraulic cylinder 63 can exert a relatively large pulling force, so as to make the rubber sleeve 61 and the inner wall of the drill hole 7 closely fit. The expansion part 6 has simple structure and no precise parts, so it is not easy to be damaged by the impact of the shock wave, and thus has long service life.

[0057] In the embodiment, the hollow pipe 9 is sleeved with a reset spring 68, and the two ends of the reset spring 68 abut against the first taper sleeve 64 and the second taper sleeve 65 respectively.

[0058] It should be noted that after the shock wave operation is completed, the piston rod 11 is controlled to move backward on the hollow pipe 9 until the first taper sleeve 64 and the second taper sleeve 65 return to the initial position. When the hollow hydraulic cylinder 63 is unloaded and contracted, the reset spring 68 can further move the first taper sleeve 64 and the second taper sleeve 65 away and return to the initial position.

[0059] In the embodiment, the number of expansion blocks 66 is four, the four expansion blocks 66 have the same structure, and the expansion blocks 66 are made of metal material.

[0060] It should be noted that the side walls of the four expansion blocks 66 abut against each other at the initial position, and after adjustment, the gap between the two expansion blocks 66 gradually increases. The four expansion blocks 66 have good fixing effect and can uniformly apply force to the rubber sleeve 61.

[0061] In the embodiment, the rubber sleeve 61 and the first taper sleeve 64 and the second taper sleeve 65 are provided with a leakage prevention ring 69, one end of the leakage prevention ring 69 abuts against the rubber sleeve 61, and the other end of the leakage prevention ring 69 abuts against the inclined surface of the first taper sleeve 64 or the second taper sleeve 65.

[0062] It should be noted that after the gap between the two expansion blocks 66 gradually increases, the two ends of the leakage prevention ring 69 abut against the rubber sleeve 61 and the first taper sleeve 64 or the second taper sleeve 65 respectively, so as to prevent water 15 from flowing out of the gap between the two expansion blocks 66.

[0063] The leakage-proof ring 69 and the rubber sleeve 61 can be formed in one piece of rubber structure, and the bulging block 66 is located in the annular space formed by the leakage-proof ring 69 and the rubber sleeve 61, so as to further improve the sealing performance.

[0064] In the embodiment, the clamping part 8 comprises a screw nut 81 and two spaced-apart conductive ends 82.

[0065] The end of the wire 24 is located between the two conductive ends 82, and the end of the screw nut 81 is screwed into the threaded hole in one of the conductive ends 82 and abuts against the wire 24.

[0066] It should be noted that the structure of the clamping part 8 facilitates the replacement of the wire 24 by the staff.

[0067] In the embodiment, the first taper sleeve 64 and the electrode seat 21 are provided with a buffer ring 13 and a clamping ring 14.

[0068] The clamping ring 14 abuts against the electrode seat 21, and the buffer ring 13 abuts against the first taper sleeve 64, and the buffer ring 13 is made of elastic material.

[0069] It should be noted that the buffer ring 13 can be made of silica gel material, and the clamping ring 14 is used to fix the buffer ring 13. The first taper sleeve 64 and the second taper sleeve 65 have the same structure, and both the first taper sleeve 64 and the second taper sleeve 65 comprise a sleeve part and a taper part connected with each other. The buffer ring 13 and the clamping ring 14 are sleeved on the sleeve part of the first taper sleeve 64, and the sleeve part is spaced apart from the electrode seat 21.

[0070] When the shock wave generator 2 performs the shock wave operation, the piston rod 11, the bulging block 66, the first taper sleeve 64 and the second taper sleeve 65 are relatively fixed with the drill hole 7, the thrust generated by the shock wave pushes the electrode seat 21 and the hollow tube 9 to move backward as a whole, and then the clamping ring 14 compresses the buffer ring 13, therefore, the buffer ring 13 can absorb certain energy, so as to improve the safety of the mechanism in use.

[0071] In the embodiment, it is obvious for those skilled in the art that the present application is not limited to the details of the above-mentioned exemplary embodiments, and the present application can be realized in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting from any point of view, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
