Description

Technical Field

[0001] The present invention relates to the technical field of underwater gate leakage plugging, and in particular to an underwater gate leakage plugging device based on a water conservancy project. Background Art

[0002] In water conservancy projects, gates, as core facilities for controlling water flow, are subject to constant impact from water flow, sediment abrasion, and chemical erosion from the water. Cracks and holes are prone to appear at the contact points between their bases and the foundation, at water-stop joints, or in the concrete itself, leading to leaks. Leakage not only wastes water resources but also weakens the stability of the gate structure. Long-term water infiltration can cause foundation settlement, corrosion of concrete reinforcement, and even lead to safety accidents such as gate overturning. Especially under high head conditions, the high-velocity water flow caused by leakage can exacerbate the expansion of defects. Therefore, timely and efficient underwater leak plugging is critical to ensuring the safe operation of water conservancy projects.

[0003] Currently, underwater plugging of gate leaks mainly relies on manual plugging by divers or traditional mechanical devices, but there are significant shortcomings: on the one hand, divers' underwater operations are limited by water flow velocity, visibility, and water pressure, resulting in high operational risks and low efficiency, making it difficult to cope with emergency water leakage scenarios; on the other hand, traditional plugging devices mostly use single-tube delivery or static plugging structures, which have problems such as severe material segregation, slow coagulation, and poor resistance to water erosion. For example, single-tube delivery is prone to interruption of operations due to blockage, static fillers are difficult to accurately cover complex defects underwater, and unmixed concrete is easily washed away by water, resulting in incomplete plugging. Therefore, there is an urgent need for an underwater plugging device for gates based on water conservancy projects to solve the above problems. Summary of the Invention

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention.

[0030] Please refer to Figures 1 - 9 , a gate underwater leakage plugging device based on a water conservancy project, including a bottom plate. The outer walls of the top of the bottom plate are fixedly connected with a shell 2 and a material box 1 for containing concrete filler. A conveying assembly for circulating and feeding the concrete is arranged inside the material box 1; One outer wall on one side of the material box 1 is fixedly connected with a box body 12 for storing accelerator; A material guide pipe 13 is arranged on one side of the material box 1. One end of the material guide pipe 13 is fixedly connected with a spray pipe 14. The bottom outer wall of the box body 12 is communicated with the material guide pipe 13 through a blanking pipe 15. An air inlet pipe 16 is fixedly connected to the circumferential outer wall of the material guide pipe 13. A driving component for providing a power source for the conveying component is arranged inside the housing 2. When the concrete filler enters the material guide pipe 13 from the elbow pipe 18, the accelerator in the box body 12 is mixed with the filler through the blanking pipe 15. At the same time, the air inlet pipe 16 is connected to a high-pressure air source. After the gas is mixed with the concrete in the material guide pipe 13, it can be ejected from the spray pipe 14 at high speed. The high-pressure air flow further improves the spraying distance of the concrete and expands the coverage range, which is suitable for the long-distance precise plugging of the gap of the gate in the deep water area; The conveying component includes fixed pipes 9 fixedly connected to the outer wall on one side of the material box 1. The number of the fixed pipes 9 is two. Piston bodies 27 are arranged inside both of the two fixed pipes 9. One outer wall of the material box 1 is rotatably connected with an elbow pipe 18. One end of the elbow pipe 18 is communicated with one of the fixed pipes 9. One end of the material guide pipe 13 is inserted into the inside of one end of the elbow pipe 18; A stirring component 17 is arranged inside the material box 1; A swinging component is arranged inside the third protective cover 10.

[0031] Furthermore, the driving assembly includes a motor 3 fixedly connected to the outer wall of the top of the housing 2. The output end of the motor 3 is fixedly connected to a first rotating column 26. A gear disc 25 is fixedly connected to the circumferential outer wall of the first rotating column 26. A piston column is fixedly connected to the circumferential inner wall of the piston body 27. A rack 24 is fixedly connected to the circumferential outer wall of the piston column. The rack 24 meshes with the gear disc 25. A cross plate 21 for ensuring the stable rotation of the gear disc 25 is fixedly connected to one inner wall of the housing 2. The two piston bodies 27 perform reciprocating alternating motions inside the two fixed pipes 9. A sliding column 20 is fixedly connected to the circumferential outer wall of the piston column. A limiting groove 4 is formed in the outer wall of the top of the housing 2. One end of the sliding column 20 passes through the inside of the limiting groove 4. A limiting disc 5 is fixedly connected to the top of the sliding column 20. The bottom outer wall of the limiting disc 5 is in contact with the outer wall of the top of the housing 2. An arc-shaped plate 19 for preventing the elbow pipe 18 from rotating excessively is fixedly connected to one inner wall of the material box 1. A second protective cover 7 and a first protective cover 6 are respectively fixedly connected to the outer walls of one sides of the material box 1 and the housing 2. The motor 3 on the top of the housing 2 is powered on. The motor 3 is a reversible motor (forward and reverse motor). When the motor 3 starts, it can drive the first rotating column 26 at its output end to rotate synchronously. At this time, the gear disc 25 on the outer wall of the first rotating column 26 rotates accordingly. The two racks 24 meshing with the gear disc 25 are driven to move left and right respectively, thereby driving the piston column and the piston body 27 to perform suction / pushing material motions inside the fixed pipe 9. When the single suction motion of the two racks 24 ends, the motor 3 rotates in the reverse direction. At this time, the gear disc 25 also rotates in the reverse direction, thereby driving the two racks 24 to move right and left respectively, thereby driving the piston column and the piston body 27 to perform pushing material / suction motions inside the fixed pipe 9. Therefore, through the continuous forward and reverse rotation of the motor 3, the piston bodies 27 in the two fixed pipes 9 perform staggered reciprocating motions, realizing the alternating suction and pushing of the concrete filler. When the left piston body 27 moves to the left, a negative pressure is formed inside the left fixed pipe 9, and the material is sucked from the material box 1 through the elbow pipe 18. When the right piston body 27 moves to the right, the concrete filler inside the right fixed pipe 9 is pushed to the elbow pipe 18. Through the alternating suction and pushing work, the continuous conveying of the concrete filler can be effectively ensured, avoiding the intermittence of the traditional single-pipe conveying, and further improving the plugging efficiency of the gate.

[0032] Furthermore, a worm 23 is fixedly connected to the circumferential outer wall of the first rotating column 26. A worm gear 22 is meshed with the circumferential outer wall of the worm 23. A second rotating rod 28 is fixedly connected to the circumferential inner wall of the worm gear 22. A second helical gear 30 is fixedly connected to the circumferential outer wall of the second rotating rod 28. A first helical gear 29 is meshed with the circumferential outer wall of the second helical gear 30. A first rotating rod 8 is fixedly connected to the circumferential inner wall of the first helical gear 29. A third helical gear 36 is fixedly connected to the circumferential outer wall of the first rotating rod 8. A fourth helical gear 37 is meshed with the circumferential outer wall of the third helical gear 36. A third rotating rod 38 is fixedly connected to the circumferential inner wall of the fourth helical gear 37. A second gear ring 35 is fixedly connected to the circumferential outer wall of the third rotating rod 38. A first gear ring 34 is meshed with the circumferential outer wall of the second gear ring 35. When the first rotating column 26 rotates, the worm 23 on its outer wall drives the worm gear 22 to rotate. Through the meshing of the second rotating rod 28, the second helical gear 30 and the first helical gear 29, the first rotating rod 8 is driven to rotate. At the same time, the third helical gear 36 on the first rotating rod 8 is meshed with the fourth helical gear 37, so that the third rotating rod 38 drives the second gear ring 35 to rotate, and then meshes with the first gear ring 34.

[0033] Furthermore, the stirring assembly 17 includes a second rotating column 39 fixedly connected to the circumferential inner wall of the first gear ring 34. A slide bar 40 is fixedly connected to the circumferential outer wall of the second rotating column 39. A sleeve 1702 is sleeved on the circumferential outer wall of the second rotating column 39. A card slot matching with the slide bar 40 is formed in the circumferential inner wall of the sleeve 1702. The number of the sleeves 1702 is two. A cross column 1706 is fixedly connected to the outer wall of one side of a sleeve 1702. The other end of the cross column 1706 is fixedly connected to the other sleeve 1702. Square tubes 1703 are fixedly connected to the circumferential outer wall of the sleeve 1702 and are distributed in a circular shape at equal intervals. Stirring rods 1705 are inserted into the square tubes 1703. A stirring plate 1701 is fixedly connected to the end of the stirring rod 1705 far away from the square tube 1703. When the first gear ring 34 rotates, the second rotating column 39 can be effectively driven to rotate. The slide bar 40 on its outer wall cooperates with the card slot on the inner wall of the sleeve 1702, so that while the sleeve 1702 rotates with the second rotating column 39, the other sleeve 1702 is driven to make a reciprocating movement through the cross column 1706. The stirring rods 1705 inserted into the square tubes 1703 on the outer wall of the sleeve 1702 and the stirring plates 1701 stir the concrete filler in the material box 1 under the combined movement of rotation and movement.

[0034] Furthermore, a tooth block 1704 is fixedly connected to the end of the square pipe 1703. The number of tooth blocks 1704 is four. The four tooth blocks 1704 clean the four side surfaces of the stirring rod 1705 respectively. During the stirring process, the tooth blocks 1704 at the end of the square pipe 1703 scrape the surface of the stirring rod 1705 to prevent the concrete from caking and ensure the fluidity of the filler. When the elbow pipe 18 swings to the left fixed pipe 9, the stirring assembly 17 moves to the entrance of the left fixed pipe 9 to quickly introduce the concrete filler into the pipe. When the elbow pipe 18 switches to the right, the stirring assembly 17 synchronously moves to the right. This dynamic stirring and feeding cooperation effectively reduces the segregation rate of the filler and improves the density of the plugging material.

[0035] Furthermore, an annular plate is fixedly connected to the inside of the material box 1, and a cover plate 11 for ensuring the internal sealing is fixedly connected to the outer wall of the top of the material box 1.

[0036] Further, the swing assembly is fixedly connected to the third gear ring 42 at the end of the elbow pipe 18. A tooth fan 41 is arranged on one side of the third gear ring 42, and the tooth fan 41 meshes with the third gear ring 42. A power assembly for driving the tooth fan 41 to rotate is arranged inside the third protective cover 10. The power assembly includes a first transmission wheel 31 fixedly connected to the outer circumference of the first rotating rod 8. A transmission belt 32 is connected to the outer circumference of the first transmission wheel 31 in a transmission manner. The first rotating rod 8 is connected to a second transmission wheel 33 through the transmission belt 32. A third rotating column 50 is fixedly connected to the inner circumference of the second transmission wheel 33. A circular shell 45 and a rotating disk 44 are fixedly connected to the outer circumference of the third rotating column 50 respectively. Swing rods 46 are fixedly connected to the outer circumference of the circular shell 45 at equal distances in a circular distribution. A sliding plate 47 is fixedly connected to the bottom outer wall of the tooth fan 41. A rectangular groove 49 is formed on one side of the sliding plate 47, and an elastic plate 48 is fixedly connected to the inside of the rectangular groove 49. An annular sliding seat 43 is fixedly connected to the outer wall of one side of the material box 1. The sliding plate 47 is slidably connected to the annular sliding seat 43. The first rotating rod 8 drives the third rotating column 50 to rotate through the first transmission wheel 31, the transmission belt 32 and the second transmission wheel 33. The circular shell 45 and the rotating disk 44 on the third rotating column 50 rotate accordingly. When the circular shell 45 rotates, the swing rods 46 on its outer wall can be driven to rotate together. When the swing rod 46 rotates to contact the elastic plate 48, the swing rod 46 will also be blocked by the elastic plate 48, so that the elastic plate 48 and the sliding plate 47 can be pushed to do circular motion together. When the sliding plate 47 does circular motion, the tooth fan 41 can be driven to rotate. Through the meshing of the tooth fan 41 and the third gear ring 42, the third gear ring 42 and the elbow pipe 18 can be driven to do circular motion together, so that the elbow pipe 18 can quickly swing to the end of another fixed pipe 9, realizing the continuous conveying of concrete filler. At the same time, when the sliding plate 47 rotates to the end of the annular sliding seat 43 and cannot rotate, the swing rod 46 will overcome the elastic force of the elastic plate 48, realizing the continuous rotation of the rotating disk 44, that is, ensuring that after the elbow pipe 18 is aligned with the fixed pipe 9, the driving assembly can continuously work to push the material inside the fixed pipe 9 out, facilitating the subsequent plugging work of the gate. When the concrete filler inside a group of fixed pipes 9 is pushed out, the driving assembly rotates in the reverse direction. At this time, the swing rod 46 will also rotate in the reverse direction. The swing rod 46 rotating in the reverse direction will push the elastic plate 48 and the sliding plate 47 to reset together again, making the tooth fan 41 swing reciprocally, driving the elbow pipe 18 to rotate around the outer wall of the material box 1. The swing of the elbow pipe 18 realizes the alternating connection of the two fixed pipes 9, avoiding the blockage of a single pipeline and improving the system stability.

[0037] In summary, by means of the above technical solution of the present invention, during use, the device is first fixed on an existing underwater robot. When the underwater robot is started, the motor 3 at the top of the housing 2 is powered on. The motor 3 is a reversible motor (forward and reverse motor). When the motor 3 starts, it can drive the first rotating column 26 at its output end to rotate synchronously. At this time, the gear disk 25 on the outer wall of the first rotating column 26 rotates accordingly, and the two racks 24 engaged with the gear disk 25 are driven to move left and right respectively, thereby driving the piston column and the piston body 27 to perform suction / pushing operations in the fixed pipe 9. When the single suction operation of the two racks 24 ends, the motor 3 rotates in the reverse direction. At this time, the gear disk 25 also rotates in the reverse direction, thereby driving the two racks 24 to move right and left respectively, and driving the piston column and the piston body 27 to perform pushing / suction operations in the fixed pipe 9. Therefore, through the continuous forward and reverse rotation of the motor 3, the piston bodies 27 in the two fixed pipes 9 perform staggered reciprocating motions, realizing the alternating suction and pushing of the concrete filler. When the left piston body 27 moves to the left, a negative pressure is formed in the left fixed pipe 9, and the material is sucked from the material box 1 through the elbow 18. When the right piston body 27 moves to the right, the concrete filler in the right fixed pipe 9 is pushed to the elbow 18. Through the alternating suction and pushing operations, the continuous conveying of the concrete filler can be effectively ensured, avoiding the intermittency of traditional single-pipe conveying, and further improving the leakage plugging efficiency of the gate; When the first rotating column 26 rotates, the worm 23 on its outer wall drives the worm wheel 22 to rotate. Through the meshing of the second rotating rod 28, the second helical gear 30 and the first helical gear 29, the first rotating rod 8 is driven to rotate. At the same time, the third helical gear 36 on the first rotating rod 8 meshes with the fourth helical gear 37, so that the third rotating rod 38 drives the second gear ring 35 to rotate, and then meshes with the first gear ring 34. At the same time, the first rotating rod 8 drives the third rotating column 50 to rotate through the first transmission wheel 31, the transmission belt 32 and the second transmission wheel 33. The circular shell 45 and the rotating disc 44 on the third rotating column 50 rotate accordingly. When the circular shell 45 rotates, the swing rod 46 on its outer wall rotates together. When the swing rod 46 rotates to contact the elastic plate 48, the swing rod 46 will also be blocked by the elastic plate 48, so that the elastic plate 48 and the slide plate 47 can be pushed to move in a circular motion together. When the slide plate 47 moves in a circular motion, it can drive the tooth fan 41 to rotate. Through the meshing of the tooth fan 41 and the third gear ring 42, the third gear ring 42 and the elbow pipe 18 can be driven to move in a circular motion together, so that the elbow pipe 18 quickly swings to the end of another fixed pipe 9, realizing the continuous conveying of the concrete filler. At the same time, when the slide plate 47 rotates to the end of the annular slide seat 43 and cannot rotate, the swing rod 46 will overcome the elastic force of the elastic plate 48, realizing the continuous rotation of the rotating disc 44, that is, ensuring that after the elbow pipe 18 is aligned with the fixed pipe 9, the driving assembly can continuously work to push the material inside the fixed pipe 9 out, facilitating the subsequent plugging work of the gate. When the concrete filler inside a group of fixed pipes 9 is pushed out, the driving assembly rotates in the reverse direction. At this time, the swing rod 46 also rotates in the reverse direction. The swing rod 46 rotating in the reverse direction will push the elastic plate 48 and the slide plate 47 to reset together again, causing the tooth fan 41 to swing reciprocally, driving the elbow pipe 18 to rotate around the outer wall of the material box 1. The swing of the elbow pipe 18 realizes the alternating connection of the two fixed pipes 9, avoiding the blockage of a single pipeline and improving the system stability; When the first gear ring 34 rotates, it can effectively drive the second rotating column 39 to rotate. The slide bar 40 on its outer wall cooperates with the card slot on the inner wall of the sleeve 1702, so that while the sleeve 1702 rotates with the second rotating column 39, the other sleeve 1702 is driven to move reciprocally through the cross bar 1706. The stirring rod 1705 and the stirring plate 1701 inserted into the square pipe 1703 on the outer wall of the sleeve 1702 stir the concrete filler in the material box 1 under the combined movement of rotation and movement. During the stirring process, the tooth block 1704 at the end of the square pipe 1703 scrapes the surface of the stirring rod 1705 to prevent the concrete from caking and ensure the fluidity of the filler. When the elbow pipe 18 swings to the left fixed pipe 9, the stirring assembly 17 moves to the entrance of the left fixed pipe 9 and quickly guides the concrete filler into the pipe. When the elbow pipe 18 switches to the right, the stirring assembly 17 moves to the right synchronously. This dynamic stirring and material guiding cooperation effectively reduces the segregation rate of the filler and improves the density of the plugging material; After the concrete filler enters the material guiding pipe 13 from the elbow pipe 18, the quick-setting agent in the box body 12 is mixed with the filler through the blanking pipe 15. At the same time, the air inlet pipe 16 is connected to a high-pressure air source. After the gas is mixed with the concrete in the material guiding pipe 13, it can be sprayed out at a high speed from the spray pipe 14. The high-pressure air flow further increases the spraying distance of the concrete, expands the coverage range, and is suitable for the long-distance precise plugging of the gate gap in deep water areas.

[0038] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
