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

A drive component for providing a power source for the conveying component is provided inside the shell 2. When the concrete filler enters the guide pipe 13 from the elbow 18, the quick-setting agent in the box body 12 is mixed with the filler through the feed pipe 15. At the same time, the air inlet pipe 16 is connected to a high-pressure gas source. After the gas is mixed with the concrete in the guide pipe 13, it can be ejected at high speed from the nozzle 14. The high-pressure airflow further increases the concrete spraying distance and expands the coverage area, making it suitable for long-distance and precise sealing of gate gaps in deep water areas.

[0044] Furthermore, the driving assembly includes a motor 3 fixedly connected to the outer wall of the top of the shell 2, the output end of the motor 3 is fixedly connected to the first rotating column 26, the circumferential outer wall of the first rotating column 26 is fixedly connected to the gear plate 25, the circumferential inner wall of the piston body 27 is fixedly connected to the piston column, the circumferential outer wall of the piston column is fixedly connected to the rack 24, the rack 24 and the gear plate 25 are meshed with each other, and the inner wall of one side of the shell 2 is fixedly connected to a horizontal plate 21 for ensuring the stable rotation of the gear plate 25. The two piston bodies 27 make reciprocating alternating motions inside the two fixed tubes 9, and the piston column The circumferential outer wall of the casing 2 is fixedly connected with a sliding post 20, a limiting groove 4 is provided on the top outer wall of the casing 2, one end of the sliding post 20 passes through the inside of the limiting groove 4, the top of the sliding post 20 is fixedly connected with a limiting plate 5, the bottom outer wall of the limiting plate 5 is in contact with the top outer wall of the casing 2, and an arc plate 19 is fixedly connected to the inner wall of one side of the material box 1 to prevent the elbow 18 from excessive rotation. The outer walls of one side of the material box 1 and the casing 2 are respectively fixedly connected with a second protective cover 7 and a first protective cover 6. The motor 3 on the top of the casing 2 is energized. The motor 3 is a reversible motor (forward and reverse motor). When the motor 3 is started, When the motor 3 is in motion, it can drive the first rotating column 26 at its output end to rotate synchronously. At this time, the gear plate 25 on the outer wall of the first rotating column 26 rotates accordingly, and the two racks 24 meshing with the gear plate 25 are driven to move left and right respectively, thereby driving the piston column and the piston body 27 to perform suction / push motion in the fixed tube 9. When the single suction motion of the two racks 24 is completed, the motor 3 rotates in the opposite direction. At this time, the gear plate 25 also rotates in the opposite 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 push / suction motion in the fixed tube 9. Therefore, through the continuous forward and reverse rotation of the motor 3, the piston bodies 27 in the two fixed pipes 9 are staggered and reciprocating, so that the concrete filler is alternately sucked and pushed. When the left piston body 27 moves to the left, negative pressure is formed in the left fixed pipe 9, and the material is sucked from the material box 1 through the bent pipe 18. When the right piston body 27 moves to the right, the concrete filler in the right fixed pipe 9 is pushed to the bent pipe 18. Through the alternating suction and pushing work, the continuous transportation of the concrete filler can be effectively ensured, avoiding the intermittent transportation of the traditional single pipe, and further improving the leakage plugging efficiency of the gate.

[0045] Furthermore, the circumferential outer wall of the first rotating column 26 is fixedly connected to the worm 23, the circumferential outer wall of the worm 23 is meshed with the worm wheel 22, the circumferential inner wall of the worm wheel 22 is fixedly connected to the second rotating rod 28, the circumferential outer wall of the second rotating rod 28 is fixedly connected to the second bevel gear 30, the circumferential outer wall of the second bevel gear 30 is meshed with the first bevel gear 29, the circumferential inner wall of the first bevel gear 29 is fixedly connected to the first rotating rod 8, the circumferential outer wall of the first rotating rod 8 is fixedly connected to the third bevel gear 36, the circumferential outer wall of the third bevel gear 36 is meshed with the fourth bevel gear 37, and the circumferential outer wall of the fourth bevel gear 37 is fixedly connected to the The third rotating rod 38 is fixedly connected to the inner wall of the circumference, and the second gear ring 35 is fixedly connected to the outer wall of the circumference of the third rotating rod 38. The outer wall of the circumference of the second gear ring 35 is meshed with the first gear ring 34. When the first rotating column 26 rotates, the worm 23 on its outer wall drives the worm wheel 22 to rotate, and the first rotating rod 8 is driven to rotate through the meshing of the second rotating rod 28, the second bevel gear 30 and the first bevel gear 29. At the same time, the third bevel gear 36 on the first rotating rod 8 is meshed with the fourth bevel 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.

[0046] Furthermore, the stirring assembly 17 includes a second rotating column 39 fixedly connected to the inner wall of the circumference of the first gear ring 34, the outer wall of the circumference of the second rotating column 39 is fixedly connected to the slide 40, the outer wall of the circumference of the second rotating column 39 is sleeved with a sleeve 1702, the inner wall of the circumference of the sleeve 1702 is provided with a slot that matches the slide 40, the number of the sleeves 1702 is two, one side outer wall of one sleeve 1702 is fixedly connected to a horizontal column 1706, the other end of the horizontal column 1706 is fixedly connected to the other sleeve 1702, the outer wall of the sleeve 1702 is fixedly connected to square tubes 1703 distributed in a circle at equal distances, and the square tubes 1703 are fixedly connected to the outer wall of the sleeve 1702. 03 is inserted into the interior of the stirring rod 1705, and the end of the stirring rod 1705 away from the square tube 1703 is fixedly connected to the stirring plate 1701. When the first gear ring 34 rotates, it can effectively drive the second rotating column 39 to rotate. The sliding bar 40 on its outer wall cooperates with the groove on the inner wall of the sleeve 1702, so that the sleeve 1702 rotates with the second rotating column 39. At the same time, the other sleeve 1702 is driven to move back and forth through the cross column 1706. The stirring rod 1705 and the stirring plate 1701 inserted into the square tube 1703 on the outer wall of the sleeve 1702 stir the concrete filler in the material box 1 under the combined motion of rotation and movement.

[0047] Furthermore, the end of the square tube 1703 is fixedly connected with a tooth block 1704, and there are four tooth blocks 1704. 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 tube 1703 scrape the surface of the stirring rod 1705 to prevent concrete from agglomerating and ensure the fluidity of the filler. When the bent 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 bent pipe 18 switches to the right, the stirring assembly 17 moves to the right synchronously. This dynamic stirring and material guidance are combined to effectively reduce the filler segregation rate and improve the density of the plugging material.

[0048] Furthermore, an annular plate is fixedly connected to the interior of the material box 1, and a cover plate 11 is fixedly connected to the top outer wall of the material box 1 for ensuring the internal sealing thereof.

[0049] Furthermore, the swing assembly is fixedly connected to the third gear ring 42 at the end of the bend pipe 18, and a gear fan 41 is provided on one side of the third gear ring 42. The gear fan 41 and the third gear ring 42 are meshed with each other. A power assembly for driving the gear fan 41 to rotate is provided inside the third protective cover 10, and the power assembly includes a first transmission wheel 31 fixedly connected to the outer wall of the circumference of the first rotating rod 8, and the outer wall of the circumference of the first transmission wheel 31 is connected to the transmission belt 32. The first rotating rod 8 is connected to the second transmission wheel 33 through the transmission belt 32. The inner wall of the circumference of the second transmission wheel 33 is fixedly connected to the third rotating column 50, and the outer wall of the circumference of the third rotating column 50 The circular shell 45 and the rotating disk 44 are fixedly connected respectively. The outer wall of the circular shell 45 is fixedly connected with the swing rod 46 distributed in a circular shape at equal distances. The outer wall of the bottom of the gear fan 41 is fixedly connected with a slide plate 47. A rectangular groove 49 is provided on one side of the slide plate 47. The interior of the rectangular groove 49 is fixedly connected with an elastic plate 48. The outer wall of one side of the material box 1 is fixedly connected with an annular slide 43. The slide plate 47 is slidably connected to the annular slide 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 When the slide plate 47 is in contact with the annular slide 43, the pendulum 46 is blocked by the elastic plate 48, thereby pushing the elastic plate 48 and the slide plate 47 to make a circular motion together. When the slide plate 47 makes a circular motion, the gear fan 41 is driven to rotate, and the gear fan 41 is meshed with the third gear ring 42, thereby driving the third gear ring 42 and the elbow 18 to make a circular motion together, so that the elbow 18 is quickly swung to the end of the other fixed pipe 9, thereby realizing continuous transportation of 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 pendulum 46 will overcome the The elastic force of the elastic plate 48 realizes the continuous rotation of the rotating disk 44, which ensures that after the curved pipe 18 is aligned with the fixed pipe 9, the driving assembly can continue to work to push out the material inside the fixed pipe 9, which is convenient for the subsequent plugging of the gate. When the concrete filler inside a group of fixed pipes 9 is pushed out, the driving assembly rotates in the opposite direction. At this time, the rocker arm 46 also rotates in the opposite direction. The reverse rotating rocker arm 46 will push the elastic plate 48 and the slide plate 47 to reset together again, so that the gear fan 41 swings back and forth, driving the curved pipe 18 to rotate around the outer wall of the material box 1. The swing of the curved pipe 18 realizes the alternating connection of the two fixed pipes 9, avoids the blockage of a single pipeline, and improves the stability of the system.

[0050] In summary, with the aid of the above technical solution of the present invention, when in use, the device is first fixed on an existing underwater robot. When the underwater robot is started, the motor 3 on the top of the shell 2 is energized. The motor 3 is a reversible motor (forward and reverse motor). When the motor 3 is started, it can drive the first rotating column 26 at its output end to rotate synchronously. At this time, the gear plate 25 on the outer wall of the first rotating column 26 rotates accordingly, and the two racks 24 engaged with the gear plate 25 are driven to move left and right respectively, thereby driving the piston column and the piston body 27 to perform suction / pushing movement in the fixed tube 9. When the single suction movement of the two racks 24 is completed, the motor 3 rotates in the reverse direction. At this time, the gear plate 25 also rotates in the reverse direction, thereby making The two racks 24 are driven to move right and left respectively, thereby driving the piston column and the piston body 27 to push / suction in the fixed tube 9. Therefore, through the continuous forward and reverse rotation of the motor 3, the piston bodies 27 in the two fixed tubes 9 are staggered and reciprocating, so that the concrete filler is alternately sucked and pushed. When the left piston body 27 moves to the left, a negative pressure is formed in the left fixed tube 9, and the material is sucked from the material box 1 through the bent tube 18. When the right piston body 27 moves to the right, the concrete filler in the right fixed tube 9 is pushed to the bent tube 18. Through the alternating suction and pushing work, the continuous transportation of the concrete filler can be effectively ensured, avoiding the intermittent transportation of the traditional single-tube, and further improving the leakage plugging efficiency of the gate.

[0051] When the first rotating column 26 rotates, the worm 23 on its outer wall drives the worm wheel 22 to rotate, and the meshing of the second rotating rod 28, the second bevel gear 30 and the first bevel gear 29 drives the first rotating rod 8 to rotate. At the same time, the third bevel gear 36 on the first rotating rod 8 meshes with the fourth bevel 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 disk 44 on the third rotating column 50 rotate accordingly. When the circular shell 45 rotates, it can drive the rocker arm 46 on its outer wall to rotate together. When the rocker arm 46 rotates to contact the elastic plate 48, the rocker arm 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 perform a circular motion together. When the slide plate 47 performs a circular motion, it can drive the gear fan 41 to rotate. 1 is meshed with the third gear ring 42, thereby driving the third gear ring 42 and the curved pipe 18 to make a circular motion together, so that the curved pipe 18 quickly swings to the end of the other fixed pipe 9, thereby realizing continuous transportation of concrete filler. At the same time, when the slide plate 47 rotates to the point where it cannot rotate with the end of the annular slide seat 43, the rocker arm 46 will overcome the elastic force of the elastic plate 48, thereby realizing continuous rotation of the rotating disk 44, that is, ensuring that after the curved pipe 18 is aligned with the fixed pipe 9, the driving component can continue to work to push the material inside the fixed pipe 9, thereby facilitating the subsequent plugging of the gate. When the concrete filler inside a group of fixed pipes 9 is pushed out, the driving component rotates in the opposite direction. At this time, the rocker arm 46 will also rotate in the opposite direction. The rocker arm 46 rotating in the opposite direction will push the elastic plate 48 and the slide plate 47 to reset together, causing the gear fan 41 to swing back and forth, driving the curved pipe 18 to rotate around the outer wall of the material box 1. The swing of the curved pipe 18 realizes the alternating connection of the two fixed pipes 9, avoids blockage of a single pipeline, and improves the stability of the system.

[0052] When the first gear ring 34 rotates, it can effectively drive the second rotating column 39 to rotate. The sliding strip 40 on its outer wall cooperates with the groove on the inner wall of the sleeve 1702, so that the sleeve 1702 rotates with the second rotating column 39. At the same time, the cross column 1706 drives the other sleeve 1702 to reciprocate. The stirring rod 1705 and the stirring plate 1701 inserted into the square tube 1703 on the outer wall of the sleeve 1702 stir the concrete filler in the material box 1 under the combined motion of rotation and movement. During the stirring process, the tooth block 1704 at the end of the square tube 1703 scrapes the surface of the stirring rod 1705 to prevent concrete from agglomerating and ensure the fluidity of the filler. When the bent pipe 18 swings to the left fixed pipe 9, the stirring assembly 17 moves to the inlet of the left fixed pipe 9 to quickly introduce the concrete filler into the pipe. When the bent pipe 18 switches to the right, the stirring assembly 17 moves to the right synchronously. This dynamic stirring and material guiding combination effectively reduces the filler segregation rate and improves the density of the plugging material.

[0053] When the concrete filler enters the guide pipe 13 from the bend pipe 18, the quick-setting agent in the box 12 is mixed with the filler through the discharge pipe 15. At the same time, the air inlet pipe 16 is connected to the high-pressure gas source. After the gas is mixed with the concrete in the guide pipe 13, it can be ejected from the nozzle 14 at high speed. The high-pressure airflow further increases the concrete spraying distance and expands the coverage area, which is suitable for long-distance and precise sealing of gate gaps in deep water areas.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
