Description

Technical Field

[0001] This application belongs to the technical field of shock wave, and particularly relates to a rod-rotating mechanism, an energy enhancement rod pushing device, and a shock wave generating device. Background Art

[0002] Coal is the most abundant and widely distributed conventional energy source in the world. Coalbed methane is a new type of energy source with high heat, cleanliness, and convenience, and has many advantages such as pollution-free and oil-free that cannot be compared with other energy sources. Coalbed methane exists in coal seams in an adsorbed state. In order to realize the industrial exploitation of coalbed methane and accelerate the drainage speed of coalbed methane in mines, a shock wave generator is often used to transform coal seams.

[0003] The existing ferry mechanism of a shock wave generator, such as the ferry mechanism involved in the patent "Ferry Mechanism, Energy Enhancement Rod Pusher, and Shock Wave Generator" with the publication number "CN110259889A", can ferry the energy enhancement rod at the front end of the energy enhancement rod pusher into the central hole of the energy enhancement rod pusher, and then push the energy enhancement rod in the central hole of the energy enhancement rod pusher into the energy converter by a push rod to drive the generation of a controllable shock wave.

[0004] However, the existing shock wave generator can only detonate energy enhancement rods with an outer diameter of 12 mm. When pre-cracking the reservoir, the diameter of the energy enhancement rod has increased to 20 mm, and the existing ferry mechanism is not suitable for ferrying energy enhancement rods of this diameter; secondly, when there are foreign objects in the pusher working in a sewage environment, the pushing mechanism and the ferry mechanism will be stuck, resulting in the inability of the shock wave generator to work. Thirdly, the ferry mechanism has a complex structure and is located at the very front end of the device. The rotational power comes from the commutation mechanism at the rear end, so it is not conducive to torque transmission; especially the ferry mechanism is very close to the energy converter, and the shock wave generated by the energy enhancement rod will directly act on the ferry mechanism, resulting in easy damage to the precision components of the ferry mechanism. Therefore, the existing ferry mechanism has poor reliability and high failure rate, and cannot meet the use requirements of the shock wave generator. Summary of the Invention

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific situations.

[0053] As Figures 1 to 14 shown, the raking mechanism provided by the embodiment of the present invention includes a bullet raking device 300 with an arc structure, an energy enhancement rod 140 transfer part arranged at the front end of the screw pusher 500, and an energy enhancement rod 140 raking part arranged at the front end of the energy storage cabin 200.

[0054] The bullet scooping device 300 and the spiral pusher 500 are arranged in the inner hole 210 provided at the center of the energy storage chamber 200, and the spiral pusher 500 is coaxially arranged with the energy storage chamber 200.

[0055] The scooping part of the energy enhancement rod 140 includes an annular groove 231 opened on the inner wall of the energy storage chamber 200, and the annular groove 231 passes through the semi-circular groove 220 provided on the inner wall of the energy storage chamber 200 for conveying the energy enhancement rod 140.

[0056] The transfer part of the energy enhancement rod 140 includes an energy enhancement rod transfer window provided on the movable sleeve 510 of the spiral pusher 500, and the energy enhancement rod transfer window communicates the outside of the movable sleeve 510 with the push rod through hole 513 at the center of the movable sleeve 510.

[0057] One side of the bullet scooping device 300 is a sharp corner structure 380, the outer arc surface of the sharp corner structure 380 abuts against the bottom wall of the annular groove 231, and the other side of the bullet scooping device 300 is installed on the movable sleeve 510, and the hole wall of the push rod through hole 513 and the inner arc surface of the bullet scooping device 300 form an energy enhancement rod scooping surface 330.

[0058] The side of the bullet scooping device 300 close to the sharp corner structure 380, the energy enhancement rod transfer window, and the spiral pusher piece 512 wound around the outer wall of the movable sleeve 510 enclose to form an energy enhancement rod inlet 390.

[0059] When the spiral pusher 500 and the bullet scooping device 300 rotate, the sharp corner structure 380 scoops up the energy enhancement rod 140, and the scooped-up energy enhancement rod 140 presses the energy enhancement rod 140 located in the energy enhancement rod transfer window and adjacent to it, and under the action of the energy enhancement rod scooping surface 330, the energy enhancement rod 140 close to the push rod through hole 513 is pushed to the center of the push rod through hole 513.

[0060] It should be noted that the energy enhancement rod 140 is placed in the semi-circular groove 220 of the energy storage chamber 200, and the energy enhancement rod 140 is located between the spiral pusher pieces 512. When the spiral pusher 500 rotates, the energy enhancement rod 140 moves in the semi-circular groove 220 towards the scooping part of the energy enhancement rod 140 under the action of the spiral pusher pieces 512. The sharp corner structure 380 moves in the annular groove 231.

[0061] Such as Figure 14As shown, when the first energy enhancement rod 140 moves to the energy enhancement rod inlet 390, the inner arc surface of the sharp corner structure 380 lifts the energy enhancement rod 140 at the annular groove 231. The spiral pusher 500 and the cartridge lifter 300 continue to rotate, causing the second energy enhancement rod 140 behind the first energy enhancement rod 140 to move forward and approach the energy enhancement rod inlet 390 under the action of the spiral pushing piece 512. The second energy enhancement rod 140 squeezes the first energy enhancement rod 140 into the energy enhancement rod inlet 390 under the action of the energy enhancement rod lifting and turning surface 330 and moves towards the center of the push rod through hole 513. By the same principle, the third energy enhancement rod 140 squeezes the second energy enhancement rod 140 to move. The second energy enhancement rod 140 is lifted by the sharp corner structure 380. At the same time, the second energy enhancement rod 140 further squeezes the first energy enhancement rod 140 to move, so that the first energy enhancement rod 140 is closer to the center of the push rod through hole 513 under the action of the energy enhancement rod lifting and turning surface 330. The spiral pusher 500 and the cartridge lifter 300 continue to rotate until the first energy enhancement rod 140 moves to the center of the push rod through hole 513. The moving principles of the second energy enhancement rod 140, the third energy enhancement rod 140, etc. are the same as that of the first energy enhancement rod 140. The first energy enhancement rod 140 that moves to the center of the push rod through hole 513 is pushed by the push rod assembly into the interior of the energy converter. During the process of the energy enhancement rod 140 moving from the semi-circular groove 220 to the center of the push rod through hole 513, the energy enhancement rod 140 moves on the energy enhancement rod lifting and turning surface 330.

[0062] In the lifting and turning mechanism of the present invention, the energy enhancement rods 140 are mutually squeezed under the action of the energy enhancement rod lifting and turning surface 330, and then the energy enhancement rods 140 are moved to the center of the push rod through hole 513. This method has simple operation and a simple structure. It can also withstand a large shock wave and can transport energy enhancement rods 140 with a larger diameter. When foreign objects in the working environment enter the pushing path of the energy enhancement rod 140, it is not easy to jam the lifting and turning mechanism. Therefore, it has high reliability and low failure rate. It avoids the problems of low torque transmission efficiency and easy damage to precision components inside the ferry mechanism when using a ferry mechanism with a complex structure. Therefore, the lifting and turning mechanism of the present invention can meet the use requirements of the shock wave generator.

[0063] In this embodiment, the energy enhancement rod transfer window includes a transition window 5161 and a flat cut window 5162 that are connected and communicate with each other.

[0064] The flat-cut window 5162 is a window formed by cutting the active sleeve 510 and the spiral pushing piece 512 along a set plane. The set plane passes through the axis of the active sleeve 510, and the cutting length of the set plane is greater than the length of the energy enhancement rod 140. After cutting the active sleeve 510 along the set plane, a first cutting surface 5163 and a second cutting surface 5164 are formed on the side wall of the active sleeve 510. The front section of the second cutting surface 5164 is located on the front side of the pushing direction of the spiral pushing piece 512 relative to the first cutting surface 5163.

[0065] The transition window 5161 is a window formed by cutting the front section of the side wall of the active sleeve 510 near the second cutting surface 5164 along a set arc surface. After cutting the active sleeve 510 along the set arc surface, a third cutting surface 5165 is formed on the side wall of the active sleeve 510. The third cutting surface 5165 is smoothly transitioned with the outer wall of the active sleeve 510.

[0066] A threaded hole 5166 is provided at the first cutting surface 5163 of the active sleeve 510, and the axis of the threaded hole 5166 is perpendicular to the first cutting surface 5163.

[0067] It should be noted that the rear section of the second cutting surface 5164 is located on the rear side of the pushing direction of the spiral pushing piece 512 relative to the first cutting surface 5163. That is, when the energy enhancement rod 140 moves, it first reaches the second cutting surface 5164. The first energy enhancement rod 140 is pushed and moved by the second energy enhancement rod 140, and the first energy enhancement rod 140 moves towards the center of the push rod through hole 513 along the outer wall of the active sleeve 510 and the third cutting surface 5165.

[0068] In this embodiment, the bullet raking device 300 includes a raking body 310 and raking claws 320 that are both arc-shaped structures.

[0069] The inner arc surface of the raking claw 320 includes a raking claw mounting surface 321 and a raking claw lifting surface 322. The sharp corner structure 380 is formed by the intersection of the raking claw lifting surface 322 and the outer arc surface of the raking claw 320.

[0070] The raking claw mounting surface 321 of the raking claw 320 is connected to the outer arc surface of the raking body 310, and the connection between the outer arc surface of the raking claw 320 and the outer arc surface of the raking body 310 is tangent.

[0071] The connection between the inner arc surface of the raking body 310 and the raking claw lifting surface 322 is tangent, and the inner arc surface of the raking body 310 and the raking claw lifting surface 322 form a first energy enhancement rod raking surface 331. The hole wall of the push rod through hole 513 and the first energy enhancement rod raking surface 331 form an energy enhancement rod raking surface 330.

[0072] It should be noted that the turning body 310 and the raking claw 320 can be integrally processed. The raking claw 320 lifts the energy enhancement rod 140 from the annular groove 231. The energy enhancement rod 140 moves from the raking surface 322 of the raking claw to the inner arc surface of the turning body 310. The connection between the inner arc surface of the turning body 310 and the raking surface 322 of the raking claw is tangent, so as to ensure the smoothness of the movement of the energy enhancement rod 140 during transportation.

[0073] In this embodiment, a raking spring installation surface 340 cooperating with the first cutting surface 5163 is provided on one side of the turning body 310 away from the raking claw 320. The turning body 310 is provided with a raking spring installation hole 350 on the raking spring installation surface 340. After the bolt passes through the raking spring installation hole 350, it is screwed into the threaded hole 5166.

[0074] It should be noted that the bolt is perpendicular to the first cutting surface 5163 and the raking spring installation surface 340. As Figure 3 shown, the raking spring 300 is installed on the spiral pusher 500, and its cross-section forms an arc structure. The formed arc structure can smoothly lift the energy enhancement rod 140, and under the interaction of multiple energy enhancement rods 140, the lifted energy enhancement rods 140 are moved into place.

[0075] In this embodiment, the raking claw 320 includes a plurality of claw hooks 323 arranged at intervals. The number of annular grooves 231 is multiple, and the plurality of claw hooks 323 correspond to the plurality of annular grooves 231 one by one.

[0076] It should be noted that the plurality of claw hooks 323 and the plurality of annular grooves 231 can apply force to the energy enhancement rod 140 evenly, so as to improve the stability of the energy enhancement rod 140 when being lifted.

[0077] In this embodiment, a plurality of energy enhancement rod pushing and sending mechanisms 360 are provided on the raking spring 300, and the plurality of energy enhancement rod pushing and sending mechanisms 360 are equidistantly distributed along the extending direction of the raking spring 300.

[0078] The energy enhancement rod pushing and sending mechanism 360 includes a pushing and sending sleeve 361, a metal ball 362, and a spring 363 arranged in the pushing and sending sleeve 361. The pushing and sending sleeve 361 is installed in the pushing and sending mechanism installation hole 370 provided on the raking spring 300. The upper part of the metal ball 362 is clamped at the mouth of the upper end of the pushing and sending sleeve 361, and the lower part of the metal ball 362 abuts against the upper end of the spring 363.

[0079] When the energy enhancement rod 140 to be pushed is located at the center of the push rod through hole 513, the energy enhancement rod 140 to be pushed and the adjacent energy enhancement rod 140 are located on both sides of the energy enhancement rod pushing and sending mechanism 360, and the outer wall of the adjacent energy enhancement rod 140 to the energy enhancement rod 140 to be pushed abuts against the metal ball 362.

[0080] It should be noted that when the pushing rod passes through the first energy enhancement rod 140 at the center of the hole 513, the spiral pusher 500 and the cartridge lifter 300 remain stationary, and the energy enhancement rod feeding mechanism 360 can prevent the second energy enhancement rod 140 on one side of it from moving towards the center of the pusher through hole 513. When the second energy enhancement rod 140 presses the metal ball 362 to move towards the center of the pusher through hole 513, the metal ball 362 will exert a certain thrust on the second energy enhancement rod 140 to ensure that the second energy enhancement rod 140 can move into place. Therefore, the energy enhancement rod feeding mechanism 360 has a simple structure and strong practicability.

[0081] In this embodiment, the multiple feeding mechanism mounting holes 370 correspond to the multiple claw hooks 323 one by one, and the axis of the feeding mechanism mounting hole 370 is located in the symmetry plane of the claw hook 323.

[0082] It should be noted that by arranging the feeding mechanism mounting hole 370 at the claw hook 323, the depth of the feeding mechanism mounting hole 370 can be made deeper, so that the energy enhancement rod feeding mechanism 360 has sufficient installation space.

[0083] In this embodiment, a chamfer structure is provided at the sharp corner structure 380. The chamfer structure can improve the structural strength at the sharp corner structure 380 and make it not easy to wear.

[0084] The embodiment of the present invention provides an energy enhancement rod pushing device, including the above-mentioned energy storage chamber 200, cartridge lifter 300, spiral pusher 500, as well as a commutator and a pusher. The commutator, pusher, spiral pusher 500, cartridge lifter 300, and energy storage chamber 200 are coaxially integrated into a whole.

[0085] The commutator drives the spiral pusher 500 to rotate, so that the spiral pusher 500 pushes the energy enhancement rod 140 to the cartridge lifter 300, and then the energy enhancement rod 140 is turned to the hole at the center of the spiral pusher 500 through the turning mechanism. The commutator drives the pusher to move forward, so that the spiral pusher 500 stops rotating, and the pusher pushes the energy enhancement rod 140 into the energy converter.

[0086] The embodiment of the present invention provides a shock wave generating device, including a high-voltage DC power supply, an energy storage capacitor, an energy controller, an energy converter, and the above-mentioned energy enhancement rod pushing device. The high-voltage DC power supply, energy storage capacitor, energy controller, and energy enhancement rod pushing device are coaxially integrated into a whole.

[0087] When in use, the high-voltage DC power supply is started to charge the energy storage capacitor. When the energy storage capacitor is charged to the set value of the energy controller, the energy capacitor is controlled to be connected to the energy converter.
