It is mainly used to fill waste or tailings and other materials in the mine through liquid filling. The main purpose of this type of equipment is to effectively fill the mine cavity, reduce the collapse and subsidence of the mine, ensure the safety of the mine, and also contribute to environmental protection and resource recycling.

[0003] Patent publication number CN117127946B discloses an integrated filling tool for downhole oilfield operations. It includes a connector, the connector being threadedly connected to a first housing, the first housing being threadedly connected to a second housing, the second housing being threadedly connected to a third housing, the connector being provided with first well-washing holes spaced equidistantly around the perimeter, the third housing being slidably and sealingly connected to a first sliding sleeve, the connector being slidably and sealingly connected to a second sliding sleeve within the connector, the inner wall of the connector being provided with blind holes spaced equidistantly around the perimeter, the blind holes of the connector being slidably connected to a first limiting rod. This patent allows well-washing, filling, and production to be completed in a single trip down the well, reducing the number of times the oil pipe and filling tool are lowered. Furthermore, four first limiting rods are used to limit the second sliding sleeve, preventing the second sliding sleeve from sliding upward due to the upward thrust of oil and gas during normal production, causing the first well-washing hole to reconnect with the second well-washing hole.

At the same time, the sliding plate is driven downward to move the connected arc baffle, so that the arc baffle pushes the connected stacked rubber ring to move down and close to the retaining ring in the plug-in ring, and the retaining ring blocks the downward moving stacked rubber ring, so that the stacked rubber ring is deformed by the upward blocking force, and the gap at the connection between the plug-in ring and the connecting end shell is filled by the stacked rubber ring. In addition, when connecting the connecting end shell and the flushing end, the torsion disk connected to the bottom of the connecting end shell is rotated to make the torsion disk drive the connected extrusion block to extrude the positioning hinge piece, so that the extrusion block extrude the positioning hinge piece and then gets stuck in the side of the positioning hinge piece.

The staff connects the external pipeline to the top of the injection port 1, and injects liquid through the external pipeline. The liquid enters the interior of the connecting end shell 2, so that the liquid inside the connecting end shell 2 enters the top of the sliding plate 55 through the outside of the pressure cylinder 51, and is forced by the sliding plate 55 to squeeze the compression spring below. The downward movement of the sliding plate 55 will drive the connected pressure cylinder 51 to move downward, and the pressure cylinder 51 moves downward to contact and push the pressure block 52, so that the push rod 53 connected to the pressure block 52 passes through the inner wall of the connecting end shell 2 and pushes the extension bar 54 to extend toward the inner wall of the mine. The extension bar 54 increases the contact area with the mine, avoiding the unstable pressure of the liquid injected into the injection port 1, which causes the connecting end shell 2 to shake as a whole and make the contact with the inner wall of the mine The loosened and fallen parts, at the same time, the downward movement of the sliding disc 55 drives the connected arc baffle 65 to move, so that the arc baffle 65 pushes the connected laminated rubber ring 513 to move down close to the baffle ring 512 in the plug-in ring 511, and the baffle ring 512 blocks the downward movement of the laminated rubber ring 513, so that the laminated rubber ring 513 is deformed by the upward blocking force, and the deformation of the laminated rubber ring 513 fills the gap at the connection between the plug-in ring 511 and the connecting end shell 2, thereby improving the sealing effect after the connection between the connecting end shell 2 and the flushing end 3, and can improve the pressure resistance between the connection structures when the liquid flows through the connecting end shell 2, thereby avoiding leakage at the connection and causing internal The liquid delivery pressure is reduced, which affects the cleaning effect of the liquid introduced into the mine. In addition, when connecting the connecting end shell 2 and the flushing end 3, by rotating the torsion disk 57 connected to the bottom of the connecting end shell 2, the torsion disk 57 drives the connected extrusion block 58 to squeeze the locking hinge 59, so that the extrusion block 58 squeezes the locking hinge 59 and then gets stuck in the side of the locking hinge 59. After being squeezed by the extrusion block 58, the locking hinge 59 pulls the spring sheet and slides through the inner ring 510 to fit into the side groove of the plug-in ring 511.

[0030] The cleaning connecting structure 6 includes a top block 61, one end of the top block 61 is fixedly connected to a slide groove 62, the middle part of the inner wall of the flushing end 3 is fixedly connected to a valve groove disc 66, the top surface of the valve groove disc 66 is rotatably connected to a turning handle 63, the top of the turning handle 63 is fixedly connected to a linkage disc 64, the top surface of the linkage disc 64 is fixedly connected to an arc baffle 65, the bottom surface of the valve groove disc 66 is rotatably connected to a pressure rotating ring 67, a squeeze block top plate 68 is provided below the pressure rotating ring 67, the inner wall of the turning handle 63 is fixedly connected to an upper baffle 69, and a lower baffle 610 is provided below the upper baffle 69.

[0031] The top of the flushing end 3 is fixedly connected to the plug ring 511, the handle 63 is slidably connected to the slide 62, the top block 61 slides from the inner wall of the flushing end 3 to the outer wall, the top plate 68 of the extrusion block is slidably connected to the inner wall of the flushing end 3, a torsion spring is provided on the bottom of the handle 63, and the two ends of the torsion spring are respectively fixedly connected to the handle 63 and the valve groove plate 66, a thin connecting rod extends downward from the bottom of the handle 63 and is fixedly connected to the pressure rotating ring 67, an arc groove is provided on the upper surface of the valve groove plate 66, and the arc groove is slidably connected to the thin connecting rod extending downward from the bottom of the handle 63, and the lower baffle 610 The retaining groove plate 72 is fixedly connected to the through-valve groove disc 66. The upward movement of the retaining groove plate 72 in the filling end 4 will push the through-valve body 73 and the upper through-tube 77 upward. The through-valve body 73 pushes the vertical spring compression upward, and extends upward to the bottom of the flushing end 3 through the upper through-tube 77 to push the extrusion block top plate 68 to slide along the inner wall of the bottom end of the flushing end 3. The extrusion block top plate 68 moves upward to squeeze the pressure-receiving swivel 67, so that the pressure-receiving swivel 67 rotates around the bottom surface of the through-valve groove disc 66 after being compressed. The rotation of the pressure-receiving swivel 67 drives the connected rotating handle 63 to rotate around the top surface of the through-valve groove disc 66. The movement of the handle 63 drives the connected linkage disk 64 and the arc baffle 65 to rotate. The arc baffle 65 is in contact with the inner wall of the flushing end 3 and rotates to block the flushing slot 8. At the same time, the handle 63 and the valve groove disc 66 move relative to each other, so that the upper baffle 69 connected to the handle 63 and the lower baffle 610 connected to the valve groove disc 66 are staggered. By rotating the handle 63, the handle 63 switches the flushing slot 8 to a connected state with the inside of the flushing end 3, so that the connecting channel can be freely switched according to the different functions of cleaning the mine or filling the goaf, so that the structures with different functions can be maximized. Sharing the same structure, the lifting structure is integrated. At the same time, when the filling end 4 is connected to the connecting end shell 2 through the turning handle 63, when the liquid flows into the flushing end 3 from the direction of the injection port 1, the outer wall of the flushing end 3 is still in the goaf in the mine. The torsion spring on the bottom side of the turning handle 63 pushes the top block 61 connected to the slide 62 to extend out of the outer wall of the flushing end 3. The upper baffle 69 and the lower baffle 610 on the bottom side of the turning handle 63 are in a closed state. At this time, the liquid used for filling in the flushing end 3 is discharged outward through the flushing slot 8 to realize the filling of the goaf.

[0032] The filling connecting structure 7 includes a bottoming pressure frame 71, the top of the bottoming pressure frame 71 is fixedly connected to a baffle plate 72, the top of the baffle plate 72 is fixedly connected to a valve body 73, the outer surface of the valve body 73 is provided with a side through groove 78, the inner bottom surface of the valve body 73 is slidably connected to a valve block 74, the top surface of the valve block 74 is fixedly connected to a valve stem 75, the outer surface of the valve stem 75 is slidably connected to a slide rod frame 76, and the outer surface of the slide rod frame 76 is fixedly connected to an upper through cylinder 77.

[0033] The bottoming pressure frame 71 slides through the bottom surface of the filling end 4 to the inside, and the upper through-tube 77 is slidably connected to the inner wall of the filling end 4. The top of the upper through-tube 77 contacts the bottom surface of the top plate 68 of the extrusion block. A small spring is provided on the outer surface of the valve stem 75, and the two ends of the small spring are fixedly connected to the valve block 74 and the sliding rod frame 76 respectively. A vertical spring is provided on the outer side of the upper through-tube 77, and the two ends of the vertical spring are fixedly connected to the valve body 73 and the filling end 4 respectively. After the mine cleaning is completed, it is necessary to extract the cleaning liquid from the mine goaf area through a plunger pump or a centrifugal pump. At this time, the filling end 4 moves downward and contacts the goaf area. By adjusting the filling end 4 and the deadweight of the connected structure, pressure is applied to the bottoming pressure frame 71, so that the bottoming pressure frame 71 moves upward relative to the adjustment filling end 4, and the bottoming pressure frame 71 pushes the connected baffle plate 72 to move. At this time, the baffle plate 72 blocks the filling slot 9, and the plunger pump or centrifugal pump generates suction through the top of the injection port 1, and discharges the air at the connection between the flushing end 3 and the filling end 4 to generate negative pressure. The liquid in the goaf area enters the filling end 4 through the liquid extraction port 10. The negative pressure causes the valve block 74 to push the connected valve stem 75 to slide along the slide rod frame 76 and squeeze the small spring. At this time, the valve block 74 is no longer Below the closed through-valve body 73, the liquid in the goaf area passes around the valve block 74 and is transported upward to the upper through-tube 77, and then flows through the flushing end 3 and the connecting end shell 2 through the upper through-tube 77 and is discharged from the top of the injection port 1. The deadweight of the filling end 4 structure as a whole falls is used to control the handle 63 to be connected to the through-valve groove plate 66. When the goaf is filled, the filling end 4 is suspended inside the goaf through the connecting pipe at the top of the injection port 1, and the flushing end 3 is in the mine and fits the well wall. At this time, the flushing notch 8 is in a closed state, the upper baffle 69 and the lower baffle 610 are staggered and in a connected state, and the liquid is passed through the injection end. The filling liquid is injected into the port 1, so that the filling liquid in the injection port 1 flows through the flushing end 3 and the connecting end shell 2 into the filling end 4, and enters the upper through tube 77 through the top of the filling end 4. The liquid injected into the upper through tube 77 pushes the closed valve body 73 below, and the valve body 73 moves downward along the inner wall of the filling end 4. Then, after the valve body 73 moves, the side through groove 78 is aligned with the filling notch 9, so that the filling liquid flowing into the valve body 73 from the upper through tube 77 is discharged from the filling notch 9 to fill the goaf, thereby controlling the ground pressure, reducing surface subsidence, and improving the filling effect.

[0034] The working principle is as follows: the staff connects the external pipe with the top of the liquid injection port 1, and injects liquid into the connecting end shell 2 through the external pipe, so that the liquid inside the connecting end shell 2 enters the top of the sliding plate 55 through the outside of the pressure cylinder 51, and is forced by the sliding plate 55 to squeeze the compression spring below. The downward movement of the sliding plate 55 will drive the connected pressure cylinder 51 to move downward, and the pressure cylinder 51 moves downward to contact and push the pressure block 52, so that the push rod 53 connected to the pressure block 52 passes through the inner wall of the connecting end shell 2 to push the extension bar 54 to extend toward the inner wall of the mine, and the contact area with the mine is increased by the extension bar 54, so as to avoid the unstable pressure of the liquid injected from the liquid injection port 1, which causes the connecting end shell 2 to shake as a whole and cause the inner wall of the mine to loosen and fall. At the same time, the downward movement of the sliding plate 55 drives the connected arc baffle 65 to move, so that the arc baffle 65 pushes the connected laminated rubber ring 513 to move down and close to the retaining ring 512 in the plug-in ring 511, and the retaining ring 512 blocks the downward movement of the laminated rubber ring 5 13, the laminated rubber ring 513 is deformed by the upward blocking force, and the gap between the plug ring 511 and the connection end shell 2 is filled by the deformation of the laminated rubber ring 513, thereby improving the sealing effect after the connection between the connection end shell 2 and the flushing end 3, and when the liquid flows through the connection end shell 2, the pressure resistance between the connection structure is improved, thereby avoiding leakage at the connection point, which leads to a decrease in the internal liquid delivery pressure and affects the cleaning effect of the liquid on the mine. In addition, when connecting the connection end shell 2 and the flushing end 3 By rotating the torsion plate 57 connected to the bottom of the connecting end shell 2, the torsion plate 57 drives the connected extrusion block 58 to squeeze the locking hinge piece 59, so that the extrusion block 58 squeezes the locking hinge piece 59 and is locked on the side of the locking hinge piece 59. After being squeezed by the extrusion block 58, the locking hinge piece 59 pulls the spring piece and slides through the inner ring 510 to fit into the groove on the side of the plug-in ring 511. The locking hinge piece 59 passes through the inner ring 510 and the plug-in ring 511 to achieve quick connection, which is convenient for subsequent quick disassembly for transportation and assembly.

[0035] The blocking groove plate 72 moves upward in the filling end 4, pushing the through valve body 73 and the upper through cylinder 77 to move upward, the through valve body 73 pushes the vertical spring to compress upward, and the upper through cylinder 77 extends upward to the bottom of the flushing end 3 to push the extrusion block top disc 68 to slide along the inner wall of the bottom end of the flushing end 3, the extrusion block top disc 68 moves upward to extrude the pressure receiving rotating ring 67, the pressure receiving rotating ring 67 rotates around the bottom surface of the through valve groove disc 66 after being pressed, the rotating ring 67 rotates around the top surface of the through valve groove disc 66 through the rotation of the pressure receiving rotating ring 67, the linkage disc 64 and the arc blocking plate 65 are rotated through the movement of the rotating handle 63, the arc blocking plate 65 is rotated and blocked in the inner wall of the flushing end 3, and the rotating handle 63 is relatively moved with the through valve groove disc 66, so that the upper blocking piece 69 connected with the rotating handle 63 and the lower blocking piece 610 connected with the through valve groove disc 66 are staggered with each other, the rotating handle 63 is switched to communicate the flushing slot 8 with the inside of the flushing end 3 through the rotation of the rotating handle 63, so as to freely switch the communication channel according to different functions of cleaning the mine or filling the goaf, so that the structures with different functions can be maximally shared in the same structure, and the structural integration is improved, at the same time, when the rotating handle 63 is connected with the connecting end shell 2 in the filling end 4, the liquid flows into the inside of the flushing end 3 from the liquid injection port 1, at this time, the outer wall of the flushing end 3 is still in the goaf in the mine, the top block 61 connected with the sliding groove 62 is extended out of the outer wall of the flushing end 3 through the torsional spring at the bottom side of the rotating handle 63, the upper blocking piece 69 and the lower blocking piece 610 at the bottom side of the rotating handle 63 are in the closed state, at this time, the liquid filled in the flushing end 3 is discharged outward through the flushing slot 8, and the filling of the goaf is realized;

[0036] After the mine cleaning is completed, it is necessary to extract the cleaning liquid from the mine goaf area by a plunger pump or a centrifugal pump. At this time, the filling end 4 moves downward and contacts the goaf area. By adjusting the dead weight of the filling end 4 and the connected structure, pressure is applied to the bottom pressure frame 71, so that the bottom pressure frame 71 is adjusted relative to the filling end 4 to move from bottom to top, and the connected baffle plate 72 is pushed to move by the bottom pressure frame 71. At this time, the baffle plate 72 blocks the filling slot 9, and the plunger pump or centrifugal pump generates suction through the top of the injection port 1, and allows the air connected between the flushing end 3 and the filling end 4 to be discharged after negative pressure is generated. The liquid in the goaf area enters the filling end 4 inside the filling end 4 through the extraction port 10. The negative pressure causes the valve block 74 to push the connected valve stem 75 to slide along the slide rod frame 76 and squeeze the small spring. At this time, the valve block 74 no longer closes the bottom of the valve body 73. The liquid in the goaf area passes around the valve block 74 and is transported upward to the upper through tube 77, and then flows through the flushing end 3 and the connecting end shell 2 through the upper through tube 77 and is discharged from the top of the injection port 1. The deadweight of the filling end 4 structure as a whole falls is used to control the handle 63 to communicate with the valve slot 66. When the goaf is filled, the filling end 4 is suspended inside the goaf through the top connecting pipe of the injection port 1. The flushing end 3 is in the mine and fits the well wall. At this time, the flushing slot 8 is in a closed state, the upper baffle 69 and the lower baffle 610 are staggered and in a connected state. The filling liquid is injected into the injection port 1, so that the filling liquid in the injection port 1 flows through the flushing end 3 and the connecting end shell 2 into the filling port. The liquid in the filling end 4 enters the upper through tube 77 through the top of the filling end 4, and the liquid injected into the upper through tube 77 pushes the closed valve body 73 below, and the valve body 73 moves downward along the inner wall of the filling end 4. Then, after the valve body 73 moves, the side through groove 78 is aligned with the filling notch 9, so that the filling liquid flowing into the valve body 73 from the upper through tube 77 is discharged from the filling notch 9 to fill the goaf, thereby controlling the ground pressure, reducing surface subsidence, and improving the filling effect.
