Description

Technical Field

[0001] The present application belongs to the field of shock wave technology, and specifically relates to a screw pusher, an energy enhancement rod pushing device, and a shock wave generating device. Background Art

[0002] Coal is the conventional energy with the largest reserves and the widest distribution in the world. Coalbed methane is a new type of energy with high heat, cleanliness and convenience. It has many advantages that other energy sources cannot match, such as no pollution and no oil pollution. Coalbed methane exists in the coal seam in an adsorbed state. In order to realize the industrial mining of coalbed methane and speed up the extraction of coalbed methane in mines, shock wave generators are often used to transform coal seams.

[0003] The energy enhancement rod pushing assembly involved in the patent "Energy enhancement rod pushing assembly, energy enhancement rod pushing device and controllable shock wave generating device" with publication number "CN111379547A" can push multiple energy enhancement rods stored on the inner wall of the energy storage cabin of the shock wave generating device one by one into the eccentric ferrying hole of the ferrying mechanism, and then push the energy enhancement rod in the center hole of the energy enhancement rod pushing device into the energy converter through the push rod to generate a controllable shock wave.

[0004] However, the existing shock wave generating device can only detonate energy enhancement rods with an outer diameter of 12mm. When the energy enhancement rod has a pre-cracking effect on the reservoir, the diameter of the energy enhancement rod has increased to 20mm. The existing energy enhancement rod pushing assembly is no longer suitable for pushing the energy enhancement rod with a larger diameter. When the ratchet of the energy enhancement rod pushing assembly pushes the energy enhancement rod in the energy storage chamber push rod through the hole into the ferrying hole of the ferrying mechanism, the ratchet needs to push multiple energy enhancement rods each time it moves. The resistance of multiple energy enhancement rods when sliding is large, and the energy enhancement rod pushing assembly has a complex structure, so the reliability is poor in actual application and the failure rate is high. At the same time, foreign matter in the working environment of the pusher will jam the pushing mechanism and the ferrying mechanism, thereby causing the shock wave generating device to fail to work. Summary of the invention

[0005] The embodiments of the present application provide a spiral pusher, an energy enhancement rod pushing device and a shock wave generating device, thereby solving the problem in the prior art that the energy enhancement rod pushing assembly has a complex structure, resulting in poor reliability and high failure rate of the energy enhancement rod pushing assembly.

[0014] In a possible implementation, the energy enhancement rod transport window includes a transition window and a flat cut window that are connected;

[0015] The flat-cut window is a window formed after the setting plane cuts the movable sleeve and the spiral push piece, the setting plane passes through the axis of the movable sleeve, and the cutting length of the setting plane is greater than the length of the energy enhancement rod; after the setting plane cuts the movable sleeve, a first cutting surface and a second cutting surface are formed on the side wall of the movable sleeve, and the front section of the second cutting surface is located at the front side of the pushing direction of the spiral push piece relative to the first cutting surface;

[0016] The transition window is a window formed after a set arc surface is cut on the front section of the movable sleeve side wall close to the second cutting surface. After the set arc surface is cut on the movable sleeve, a third cutting surface is formed on the side wall of the movable sleeve; the third cutting surface smoothly transitions with the outer wall of the movable sleeve.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In the description of the embodiments of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limitations on the present invention. The terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, 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 a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a connection between the 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 the specific circumstances.

[0037] like Figures 1 to 8 As shown, the spiral pusher provided in the embodiment of the present invention includes a movable sleeve 510 and a spiral push piece 512 evenly wound on the outer wall of the movable sleeve 510, and the spiral push piece 512 is perpendicular to the outer wall of the movable sleeve 510; the spiral push piece 512 forms a conveying space for the energy enhancement rod 140 on the outer wall of the movable sleeve 510;

[0038] The center of the movable sleeve 510 is provided with a push rod through hole 513 for the push rod to pass through, the front end of the movable sleeve 510 is connected to an energy converter connection end 514, and the rear end of the movable sleeve 510 is connected to a reversing mechanism connection end 515;

[0039] An energy enhancement rod 140 transfer portion is disposed at the front end of the movable sleeve 510 , and the energy enhancement rod 140 transfer portion includes an energy enhancement rod 140 transfer window disposed on the movable sleeve 510 , and the energy enhancement rod 140 transfer window connects the outside of the movable sleeve 510 with the push rod through hole 513 .

[0040] It should be noted that the screw pusher 500 of the present invention is coaxially fixed in the energy storage cabin 200 , and a semicircular groove 220 for conveying the energy enhancement rod 140 is provided on the inner wall of the energy storage cabin 200 , and the semicircular groove 220 is parallel to the axis of the energy storage cabin 200 . The energy enhancement rod 140 is placed in the semicircular groove 220 of the energy storage cabin 200, and the energy enhancement rod 140 is located between the spiral pushing pieces 512, and the spiral pusher 500 is rotated. The energy enhancement rod 140 moves in the semicircular groove 220 under the action of the spiral pushing pieces 512, thereby realizing the pushing of the energy enhancement rod 140. The present invention avoids the use of a complex pawl pushing component. The spiral pusher 500 has a simple structure, and foreign objects in the working environment enter the pushing path of the energy enhancement rod 140 and will not jam the spiral pusher 500; when the energy enhancement rod 140 is pushed, the spiral pushing piece 512 only needs to push the energy enhancement rod 140 on one side thereof, and multiple energy enhancement rods 140 are pushed separately, so the resistance is small when the energy enhancement rod 140 is pushed, thereby improving the reliability of the energy enhancement rod 140 when pushing, and reducing the failure rate of the pusher.

[0041] The push rod is installed in the push rod through hole 513. When the energy enhancement rod 140 is pushed to the energy enhancement rod 140 transfer window, the energy enhancement rod 140 is transferred to the center of the movable sleeve 510 through the energy enhancement rod 140 rotation mechanism, and then the energy enhancement rod 140 can be pushed into the energy converter through the reversing mechanism and the push rod.

[0042] like Figure 4 As shown, in this embodiment, the reversing mechanism connection end 515 is provided with a reversing mechanism docking hole 5151, the aperture of the reversing mechanism docking hole 5151 is larger than the aperture of the push rod through hole 513, and the side wall of the reversing mechanism docking hole 5151 is provided with a positioning groove body 5152, and the extension direction of the positioning groove body 5152 is parallel to the axis of the reversing mechanism docking hole 5151.

[0043] It should be noted that the reversing mechanism docking hole 5151 is docked with the connector of the reversing mechanism, the connector end face abuts against the bottom face of the reversing mechanism docking hole 5151, and the positioning groove 5152 is used to cooperate with the key on the connector, thereby fixing the connector.

[0044] In this embodiment, spiral guide rails for supporting the energy enhancement rod 140 are provided on both sides of the spiral push piece 512 ; and rounded corners are provided between the two sides of the spiral push piece 512 and the outer wall of the movable sleeve 510 .

[0045] It should be noted that the energy enhancement rod 140 is placed between the spiral push pieces 512, and both ends of the energy enhancement rod 140 are supported by spiral guide rails. When the energy enhancement rod 140 is pushed, the spiral guide rails can reduce the contact area between the movable sleeve 510 and the energy enhancement rod 140, thereby reducing the friction force, thereby facilitating the pushing of the energy enhancement rod 140. The rounded corners between the spiral push piece 512 and the movable sleeve 510 are adapted to the end of the energy enhancement rod 140, thereby facilitating the spiral push piece 512 to push the energy enhancement rod 140.

[0046] In this embodiment, a plurality of pressure relief holes 511 are provided on the side wall of the movable sleeve 510 .

[0047] It should be noted that when the pusher is pushed in the borehole, the pusher is in the water in the borehole. When water enters the pusher, it will form a certain pressure inside the pusher, and the pressure relief hole 511 can balance the water pressure inside and outside the movable sleeve 510, thereby avoiding safety problems caused by water pressure imbalance.

[0048] In this embodiment, the height of the spiral push piece 512 is one third of the diameter of the energy enhancement rod 140 .

[0049] It should be noted that the depth of the semicircular groove 220 of the energy storage cabin 200 is one-third of the diameter of the energy enhancement rod 140. When the energy enhancement rod 140 is pushed, the spiral pushing piece 512 of this height can well drive the energy enhancement rod 140 to slide in the semicircular groove 220. At the same time, the interval between the spiral pushing piece 512 and the semicircular groove 220 facilitates the installation of the energy enhancement rod 140.

[0050] In this embodiment, the energy converter connection end 514 includes a first ring body 5141 and a second ring body 5142 connected to each other, and the end of the second ring body 5142 away from the first ring body 5141 is connected to the movable sleeve 510, the inner diameter of the first ring body 5141 and the inner diameter of the second ring body 5142 are equal to the inner diameter of the push rod through hole 513, and the outer diameter of the first ring body 5141 is smaller than the outer diameter of the second ring body 5142.

[0051] It should be noted that the first ring body 5141 is inserted into the hole at the rear end of the energy converter, and the end face of the second ring body 5142 abuts against the rear end of the energy converter. The energy converter connection end 514 and the rear end of the energy converter can be connected by an insulator to improve the sealing and insulation performance of the connection.

[0052] like Figure 3 As shown, in this embodiment, the transfer window of the energy enhancement rod 140 includes a transition window 5161 and a flat cutting window 5162 that are connected;

[0053] The flat-cut window 5162 is a window formed after the setting plane cuts the movable sleeve 510 and the spiral push piece 512. The setting plane passes through the axis of the movable sleeve 510, and the cutting length of the setting plane is greater than the length of the energy enhancement rod 140. After the setting plane cuts the movable sleeve 510, a first cutting surface 5163 and a second cutting surface 5164 are formed on the side wall of the movable sleeve 510. The front section of the second cutting surface 5164 is located at the front side of the pushing direction of the spiral push piece 512 relative to the first cutting surface 5163.

[0054] The transition window 5161 is a window formed by cutting the front section of the side wall of the movable sleeve 510 close to the second cutting surface 5164 with a set arc surface. After the movable sleeve 510 is cut with a set arc surface, a third cutting surface 5165 is formed on the side wall of the movable sleeve 510; the third cutting surface 5165 smoothly transitions with the outer wall of the movable sleeve 510.

[0055] It should be noted that the screw pusher 500 is coaxially fixed in the energy storage cabin 200, the bomb-carrying device 300 is fixed at the opening at the front end of the movable sleeve 510, and the inner arc surface of the bomb-carrying device 300 and the inner wall of the movable sleeve 510 form a continuous rotating arc surface; the screw pusher 500 is rotated, and the bomb-carrying device 300 rotates with the screw pusher 500, and the first energy enhancement rod 140 is picked up from the semicircular groove 220 by the claw 320 of the bomb-carrying device 300, so that the first energy enhancement rod 140 is located on the claw 320; the screw pusher 500 is continued to rotate, and the second energy enhancement rod 140 moves forward under the action of the spiral pushing piece 512 and is connected with the first energy enhancement rod 140. The strong rod 140 abuts against the second energy enhancement rod 140, and then the second energy enhancement rod 140 is picked up from the semicircular groove 220 by the claw 320. During the process of picking up the second energy enhancement rod 140, the second energy enhancement rod 140 and the first energy enhancement rod 140 approach the center of the screw pusher 500 under the action of the rotating arc surface; the screw pusher 500 continues to rotate, and the third energy enhancement rod 140 abuts against the second energy enhancement rod 140. The second energy enhancement rod 140 and the first energy enhancement rod 140 approach the center of the screw pusher 500 under the action of the rotating arc surface until the first energy enhancement rod 140 is rotated to the center of the screw pusher 500.

[0056] The rear section of the second cutting surface 5164 is located at 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. Under the action of the ejector 300, the second energy enhancement rod 140 and the first energy enhancement rod 140 approach the center of the spiral pusher 500, and the first energy enhancement rod 140 moves toward the center of the push rod through hole 513 along the outer wall of the movable sleeve 510 and the third cutting surface 5165. Therefore, the smooth transition of the third cutting surface 5165 and the outer wall of the movable sleeve 510 can facilitate the force transfer of the energy enhancement rod 140, while preventing the outer wall of the energy enhancement rod 140 from being scratched.

[0057] In this embodiment, the movable sleeve 510 is provided with a threaded hole 5166 at the first cutting surface 5163 , and the axis of the threaded hole 5166 is perpendicular to the first cutting surface 5163 .

[0058] It should be noted that the bomb holder 300 can be installed on the movable sleeve 510 by means of bolts and nuts, and can form an energy enhancement rod 140 rotation mechanism in conjunction with the energy storage cabin 200. The energy enhancement rod 140 rotation mechanism can transfer the energy enhancement rod 140 from the outer wall of the movable sleeve 510 to the center of the movable sleeve 510.

[0059] The embodiment of the present invention also provides a pushing device for an energy enhancement rod 140, including a commutator, a push rod, an energy storage cabin 200, a bullet collector 300, and the above-mentioned screw pusher 500. The commutator, the push rod, the screw pusher 500, the bullet collector 300, and the energy storage cabin 200 are coaxially integrated into a whole.

[0060] The commutator drives the screw pusher 500 to rotate, so that the screw pusher 500 pushes the energy enhancement rod 140 to the ejector 300, and then the energy enhancement rod 140 is rotated to the hole in the center of the screw pusher 500 through the ejector 300; the commutator drives the push rod to move forward, so that the screw pusher 500 stops rotating, and the push rod pushes the energy enhancement rod 140 into the energy converter.

[0061] An embodiment of the present invention also 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 140 pushing device, wherein the high-voltage DC power supply, the energy storage capacitor, the energy controller, and the energy enhancement rod 140 pushing device are coaxially integrated into a whole.

[0062] 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. The pulse high voltage is loaded on the energy enhancement rod 140 in the energy converter to generate shock waves to increase the permeability of the coal seam.

[0063] In this embodiment, it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and therefore it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
