Description

Technical Field

[0001] The present application belongs to the field of shock wave technology, and specifically relates to a micro-tooth type commutator, 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 micro-tooth commutator of the existing shock wave generator, such as the commutation mechanism involved in the patent "Deep and Shallow Groove Reversing Mechanism, Energy Rod Pusher and Shock Wave Generator" with the publication number "CN110206523A", can continuously and repeatedly push the energy enhancement rod from the energy storage compartment into the ferry mechanism, and further push it into the energy converter to generate controllable shock waves. However, the existing shock wave generator can only detonate the energy enhancement rod with an outer diameter of 12mm. When the reservoir is pre-splitting, the diameter of the energy enhancement rod has increased to 20mm, which cannot be achieved by the existing pushing method. At the same time, the deep and shallow groove reversing mechanism uses a stepper motor as the power. First, the motor's rotational motion is changed into linear motion through the lead screw to push the energy enhancement rod forward, and then the linear motion is changed into rotational motion through the reversing mechanism to ferry the energy enhancement rod from the energy storage cabin to the center hole. Although it has achieved linear and rotational motion in steps with only one motor, the multiple reversals cause the motor's torque transmission loss to be large, especially when there are foreign objects in the pusher working in a potential pollution environment, it will be directly stuck and unable to work. Thirdly, the ferry mechanism at the front end has a complex structure and is at the top of the equipment. The rotational power comes from the reversing mechanism at the bottom, which is not conducive to torque transmission, thus affecting the normal use of the shock wave generator.

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.

[0031] like Figure 1 As shown, the micro-tooth commutator provided by the embodiment of the present invention includes a third housing 710, a push rod 400, and a joint 720, a driven plane gear 730, a driving plane gear 740 and a motor 750 which are sequentially arranged in the third housing 710 from front to back.

[0032] The joint 720 is rotatably mounted at the front end of the third shell 710 via a one-way bearing 770. A step hole is provided in the joint 720. The step hole includes a small hole 721 and a large hole 722 provided at the rear end of the small hole 721. A slide groove 725 is provided on the side wall of the large hole 722. The extension direction of the slide groove 725 is parallel to the axis of the third shell 710.

[0033] The driven plane gear 730 is installed in the large hole 722 . A pin 732 is provided on the side wall of the driven plane gear 730 . The end of the pin 732 is clamped in the slide groove 725 .

[0034] A threaded sleeve 760 is disposed on the output shaft of the motor 750 , and an inner wall of the threaded sleeve 760 is provided with internal threads. The driving plane gear 740 is mounted on the threaded sleeve 760 , and matching teeth are disposed on opposite sides of the driving plane gear 740 and the driven plane gear 730 .

[0035] The push rod 400 includes a lower push rod 430 and a lead screw 440 arranged at the rear end of the lower push rod 430. The aperture of the small hole 721 is greater than the diameter of the lower push rod 430, the inner diameter of the driven plane gear 730, and the diameter of the lead screw 440. The lead screw 440 passes through the holes in the center of the joint 720, the driven plane gear 730, and the driving plane gear 740 in sequence and then is screwed into the threaded sleeve 760.

[0036] A guide groove 441 is provided on the side wall of the lead screw 440 , and the guide groove 441 is arranged parallel to the axis of the lead screw 440 . A guide block 731 is provided on the hole wall of the center hole of the driven plane gear 730 , and the guide block 731 is clamped in the guide groove 441 .

[0037] The motor 750 drives the threaded sleeve 760 to rotate, causing the lead screw 440 to move backward, thereby causing the push rod 430 to abut against the driven plane gear 730 and push the driven plane gear 730 to move, thereby causing the driven plane gear 730 to mesh with the driving plane gear 740, and the driven plane rotates and drives the joint 720 to rotate.

[0038] In this embodiment, the front end of the third shell 710 is provided with a docking portion for connecting with the rear end of the energy storage compartment, and the inner wall of the front end of the third shell 710 is provided with an annular protrusion 711. The annular protrusion 711 is located behind the docking portion.

[0039] The joint 720 is a columnar structure, and includes a docking section 723 and a mounting section 724 disposed at the rear end of the docking section 723 . The outer diameter of the docking section 723 is smaller than the outer diameter of the mounting section 724 .

[0040] The docking section 723 passes through the annular protrusion 711, and a one-way bearing 770 is mounted on the docking section 723. The outer wall of the one-way bearing 770 abuts against the annular surface of the annular protrusion 711, and a pusher installation key for connecting to the rear end of the screw pusher is provided at the front end of the docking section 723.

[0041] It should be noted that the end of the pin 732 is engaged in the slide groove 725, so the driven plane gear 730 can slide in the large hole 722 of the joint 720. The docking portion adopts a threaded connection. The joint 720 can rotate freely in one direction under the action of the one-way bearing 770, and is locked in the other direction. When the docking section 723 rotates, the screw pusher is driven to rotate. The front part of the push rod 400 is located in the hole in the center of the screw pusher.

[0042] The threaded sleeve 760 is driven to rotate by the motor 750. Since the guide block 731 of the driven plane gear 730 is clamped in the guide groove 441 of the side wall of the screw 440, the screw 440 moves backward, that is, the push rod 400 moves backward, and the lower push rod 430 passes through the small hole 721 of the joint 720 and abuts against one side of the driven plane gear 730. The motor 750 continues to rotate, so that the lower push rod 430 pushes the driven plane gear 730 to move until the driven plane gear 730 and the driving plane gear 740 are meshed. Since the driving plane gear 740 is installed on the threaded sleeve 760, the driving plane gear 740 drives the driven plane gear 730 to rotate, and the driven plane gear 730 drives the joint 720 to rotate, thereby driving the spiral pusher to rotate. When the spiral pusher rotates, the energy enhancement rod is pushed to the center of the spiral pusher. At this time, the energy enhancement rod is located at the front end of the push rod 400.

[0043] The motor 750 is controlled to rotate in the opposite direction, and the motor 750 drives the threaded sleeve 760 to rotate in the opposite direction. Since the one-way bearing 770 is locked in the opposite direction, the position of the joint 720 is fixed, and the position of the screw pusher is fixed, that is, the driven plane gear 730 does not rotate, and since the guide block 731 of the driven plane gear 730 is engaged in the guide groove 441 of the side wall of the screw 440, the screw 440 moves forward, the driven plane gear 730 and the driving plane gear 740 are disengaged, and the screw 440 continues to move forward, that is, the push rod 400 moves forward, and the energy enhancement rod at the center of the screw pusher is pushed into the energy converter during the forward movement of the push rod 400. Then repeat the above steps to transport the next energy enhancement rod to the center of the screw pusher, and then push the energy enhancement rod at the center of the screw pusher into the energy converter through the push rod 400.

[0044] The micro-tooth commutator of the present invention utilizes the driven plane gear 730 and the driving plane gear 740 to realize the conversion between linear motion and rotational motion, so that the torque transmission efficiency of the motor of the micro-tooth commutator is high. The micro-tooth commutator has a simple structure and is not easily stuck by foreign objects in a potentially polluted environment, thereby ensuring the reliability of the energy enhancement rod when it is pushed. The micro-tooth commutator can be used to push energy enhancement rods with large diameters, thereby meeting the use requirements of the shock wave generator.

[0045] In this embodiment, the docking section 723 and the one-way bearing 770 are connected via a first bearing installation key 771 , and the one-way bearing 770 and the annular protrusion 711 are connected via a second bearing installation key 772 .

[0046] It should be noted that fixing the bearing by the first bearing installation key 771 and the second bearing installation key 772 is not only easy to install but also has high reliability.

[0047] In this embodiment, a reducer 780 is further included and is disposed between the driving plane gear 740 and the motor 750 . The reducer 780 is fixed in the third housing 710 .

[0048] The threaded sleeve 760 passes through the reducer 780 , an input gear ring 781 of the reducer 780 is fixedly connected to the threaded sleeve 760 , and the driving plane gear 740 is installed on an output gear ring 782 of the reducer 780 .

[0049] A sleeve mounting bearing 761 is provided between the reduction wheel of the reducer 780 and the threaded sleeve 760 .

[0050] It should be noted that the reduction ratio of the reducer 780 used in the present invention is more than 8 times. The threaded sleeve 760 drives the input gear ring 781 to rotate, and after being decelerated by the reduction gear ring and the reduction wheel in the reducer 780, it is output through the output gear ring 782 and drives the driving plane gear 740 to rotate. The sleeve mounting bearing 761 enables the threaded sleeve 760 to rotate relative to the reduction wheel of the reducer 780, thereby improving the structural stability of the reducer 780.

[0051] In this embodiment, the two opposite end faces of the driving plane gear 740 and the driven plane gear 730 are both provided with docking grooves 741, and the part of the screw 440 located in the docking groove 741 is sleeved with a return spring 742, and the end of the return spring 742 abuts against the bottom of the docking groove 741.

[0052] It should be noted that when the lead screw 440 moves forward, the driven plane gear 730 can be disengaged from the driving plane gear 740 under the action of the return spring 742 and gradually return to the initial state, preventing the driven plane gear 730 from driving the screw pusher to rotate through the joint 720.

[0053] In this embodiment, the cross-sections of the teeth on the driving plane gear 740 and the driven plane gear 730 are in the shape of a right triangle, and the teeth drive the driven plane gear 730 to rotate when the driving plane gear 740 rotates clockwise or counterclockwise.

[0054] It should be noted that the right-angled triangle-shaped teeth can enable the driving plane gear 740 to drive the driven plane gear 730 to rotate in only one direction after the driving plane gear 740 and the driven plane gear 730 are meshed, thereby ensuring that when the motor 750 rotates in the opposite direction, even if the driving plane gear 740 and the driven plane gear 730 are meshed, the driving plane gear 740 will not drive the driven plane gear 730 to rotate, thereby improving the working reliability of the micro-tooth commutator.

[0055] An embodiment of the present invention also provides an energy enhancement rod pushing device, including an energy storage cabin, a push rod 400, a screw pusher, a bullet collector, and a micro-tooth commutator as described above, wherein the micro-tooth commutator, the push rod 400, the screw pusher, the bullet collector, and the energy storage cabin are coaxially integrated into a whole.

[0056] The micro-tooth commutator drives the screw pusher to rotate, so that the screw pusher pushes the energy enhancement rod to the bomb collector, and then the energy enhancement rod is rotated to the hole in the center of the screw pusher through the bomb collector.

[0057] The micro-tooth commutator drives the push rod 400 to move forward, thereby stopping the rotation of the screw pusher 5, and the push rod 400 pushes the energy enhancement rod into the energy converter.

[0058] 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 an energy enhancement rod pushing device as described above, wherein the high-voltage DC power supply, the energy storage capacitor, the energy controller and the energy enhancement rod pushing device are coaxially integrated into a whole.

[0059] 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 in the energy converter to generate a shock wave to increase the permeability of the coal seam. 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 the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in the present invention.
