Description

Technical Field

[0001] The invention belongs to the technical field of hydraulic gates, and in particular relates to a self-cleaning hydraulic gate. Background Art

[0002] A hydraulic gate is a structure used in hydraulic projects, typically constructed of metal, wood, or concrete, to control water flow. It can close or partially open openings in hydraulic structures as needed to regulate upstream and downstream water levels, control flow velocity, manage discharge flow, release vessels, and remove sediment and other floating debris. Widely used in water conservancy facilities such as rivers and reservoirs, hydraulic gates are a crucial component of hydraulic projects.

[0003] Existing gates lack cleaning measures when in use. The gates are immersed in water for a long time, and algae and dirt are easily grown on their surfaces, which damages and erodes the gate surface, resulting in a reduction in the service life of the gate. When the gate is closed to seal the water outlet, mud, sand and gravel are easily accumulated at the bottom of the water-facing surface of the gate. As time goes by, the mud, sand and gravel accumulated at the bottom become more and more, forming accumulation blocks. When the gate is opened to release water next time, the accumulation blocks will affect the effect of water release, and the accumulation of accumulation blocks is difficult to clean. At the same time, since mud and sand will inevitably flow into the canal when the gate is opened to release water, the colloids or suspended particles in the water will stick to the bottom of the canal due to their own viscosity, affecting the conveying efficiency of the canal.

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail with reference to the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention. The technical solutions of the present invention will be described in detail below with reference to the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0025] See also Figures 1 to 8 This embodiment provides a self-cleaning water conservancy gate, including a gate 4, a cleaning mechanism, an energy storage mechanism, and a scrubbing mechanism. Bases 2 are symmetrically mounted on both sides of a water channel 1. Gate frames 3 are fixedly connected to the tops of the two bases 2, and gates 4 are mounted inside the gate frames 3.

[0026] A cleaning mechanism is installed on one side of the gate 4, and the cleaning mechanism includes a tooth groove 7, a cleaning rod 8, a rotating gear 9 and a brush 10. The tooth grooves 7 are opened on the left and right sides of the outer surface of the gate 4, and the cleaning rod 8 is rotatably installed on the inner wall of the gate frame 3; the outer sides of the cleaning rod 8 are fixedly connected to the rotating gears 9 at both ends, and the rotating gears 9 are meshed with the corresponding tooth grooves 7. The brushes 10 are installed on the outer sides of the cleaning rod 8 in sequence and equidistantly. Since the tooth grooves 7 opened on the outer surface are meshed with the rotating gears 9, when the gate 4 moves upward, the tooth grooves 7 cooperate to drive the rotating gears 9 to rotate, and the rotation of the rotating gears 9 drives the cleaning rod 8 to rotate, and the rotation of the cleaning rod 8 drives the brushes 10 installed on the outer side to rotate, and the brushes 10 are used to clean the outer surface of the gate 4.

[0027] A driving motor 6 is installed on the top of the gate frame 3. The output end of the driving motor 6 passes through the interior of the gate frame 3 and is fixedly connected to a threaded rod 5. The bottom of the threaded rod 5 is threadedly connected to the gate 4. When the driving motor 6 is started, the driving motor 6 drives the threaded rod 5 to rotate, and the rotation of the threaded rod 5 drives the gate 4 connected at the bottom to move upward.

[0028] A guide rod 11 is slidably installed inside the gate 4, and a transfer rod 12 is slidably installed inside the center of the gate 4. A driven gear 13 is fixedly connected to the outer side of the top of the transfer rod 12. A first pulley 14 is installed on the outer side of the threaded rod 5 and the guide rod 11. A first connecting belt 15 is installed between the two first pulleys 14, and the first connecting belt 15 is engaged with the driven gear 13; a rectangular groove 18 is provided inside the first connecting belt 15; a recovery groove 16 is provided at the bottom of the gate 4, and a brush plate 17 is installed inside the recovery groove 16, and the brush plate 17 is fixedly connected to the transfer rod 12 inside.

[0029] When the drive motor 6 is running, it drives the threaded rod 5 to rotate, and the rotation of the threaded rod 5 raises the gate 4; and when the drive motor 6 is running, it drives the first pulley 14 on the outside of the threaded rod 5 to rotate together, and the first pulley 14 drives the driven gear 13 to rotate through the cooperation of the first connecting belt 15, and the rotation of the driven gear 13 drives the transmission rod 12 to rotate, and the transmission rod 12 drives the brush plate 17 to rotate; since a rectangular groove 18 is provided inside the first connecting belt 15, when the first connecting belt 15 rotates, it does not directly engage with the driven gear 13 to drive the driven gear 13 to rotate, and the transmission rod 12 drives the brush plate 17 to rotate. Until the driven gear 13 is meshed with the first connecting belt 15 again, the first connecting belt 15 drives the driven gear 13 to rotate, and the rotation of the driven gear 13 drives the bottom transmission rod 12 and the brush plate 17 to rotate together, and the rotation of the brush plate 17 breaks up and scrapes the mud, sand and gravel accumulated at the gate 4.

[0030] The energy storage mechanism includes a storage tank 19 provided on the side of the base 2, a blocking block 20 is installed inside the storage tank 19, a support rod 21 is fixedly connected to the top of the blocking block 20, and a connecting block 22 is fixedly connected to the outside of the support rod 21; a sliding groove 23 is symmetrically opened on the inner wall of the top of the gate frame 3, the top of the support rod 21 is slidably connected to the sliding groove 23, a rack 24 is fixedly connected to one side of the connecting block 22, and a connecting rod 25 is rotatably installed on the top of the gate frame 3; the connecting rod 25 is located between the two sliding grooves 23; an arc gear 26 is fixedly connected to the outside of the connecting rod 25, and the arc gear 26 is meshed with the rack 24. A second pulley 27 is installed at the bottom of the connecting rod 25 and the outside of the transmission rod 12, and a second connecting belt 28 is installed between the two second pulleys 27.

[0031] When the transmission rod 12 rotates, the arc gear 26 is driven to rotate through the cooperation of the second pulley 27 and the second connecting belt 28. Since the arc gear 26 is meshed with the rack 24 on the outer side, when the arc gear 26 rotates, it drives the two racks 24 to move together. The movement of the rack 24 pulls the blocking block 20 to move together through the cooperation of the connecting block 22 and the support rod 21 until the two blocking blocks 20 are spliced together; the blocking block 20 reduces the water flow surface at the gate 4, and strengthens the kinetic energy of the water flow at the same flow rate, so as to better impact the mud, sand and gravel accumulated at the gate 4 and disperse and clean them.

[0032] The back surface of the gate 4 is equipped with a scrubbing mechanism, which includes a crossbar 37, a moving block 36, a connecting frame 38, a first rotating rod 39, and a guide vane 40. The moving blocks 36 are provided on the outside of the two side walls of the gate frame 3. One side of the moving block 36 is fixedly connected to the crossbar 37. A connecting frame 38 is installed between the two crossbars 37. The first rotating rod 39 is rotatably installed inside the connecting frame 38. The outer side of the first rotating rod 39 is fixedly connected to the guide vanes 40 in sequence and at equal intervals. The inner side of the connecting frame 38 is rotatably installed with a second rotating rod 41. The outer side of the second rotating rod 41 is fixedly connected to a cleaning rod 42 in sequence and at equal intervals. A third pulley 43 is installed at one end of each of the first rotating rod 39 and the second rotating rod 41. A third connecting belt 44 is installed between the two third pulleys 43. When the drainage blade 40 is driven by the water flow, it will drive the first rotating rod 39 to rotate. The rotation of the first rotating rod 39 drives the second rotating rod 41 to rotate through the cooperation of the third pulley 43 and the third connecting belt 44. The rotation of the second rotating rod 41 drives the cleaning rod 42 to rotate. The rotation of the cleaning rod 42 will clean the bottom of the canal. When colloids or suspended particles pass through the cleaning rod 42, the cleaning rod 42 rotates to break them up, thereby preventing them from sticking to the bottom of the canal.

[0033] A reciprocating screw 45 is rotatably mounted within the connecting frame 38. A reciprocating block 46 is meshedly connected to the outside of the reciprocating screw 45. A displacing plate 47 is fixedly connected to the front end of the reciprocating block 46. A fourth pulley 48 is mounted on one end of each of the reciprocating screw 45 and the first rotating rod 39. A fourth connecting belt 49 is mounted between the two fourth pulleys 48. When the first rotating rod 39 rotates, the third connecting belt 44 and the fourth pulley 48 cooperate to drive the reciprocating screw 45 to rotate. The rotation of the reciprocating screw 45 drives the meshed reciprocating block 46 to move. The movement of the reciprocating block 46 drives the displacing plate 47 to move. The movement of the displacing plate 47 displaces and disperses floating objects on the surface of the water flow, pushing the floating objects to the banks on both sides of the canal.

[0034] A worm gear 29 is rotatably mounted on the top of the gate frame 3, and the interior of the worm gear 29 is fixedly connected to the transmission rod 12. A worm 30 is rotatably mounted on the top of the gate frame 3, and a winch 33 is mounted on both ends of the worm 30. A set of movable slots 31 are symmetrically opened on both side walls of the gate frame 3, and a set of movable slots 31 includes two vertical and parallel movable slots 31 in front and back; a cross bar 37 is slidably connected to the movable slot 31 located on the rear side; movable blocks 32 are mounted on both side walls of the gate frame 3, and the movable blocks 32 are slidably connected to the movable slot 31 in the front side; and the movable blocks 32 are connected to the movable blocks 36 on the same side. A fixed disk 34 is mounted on the outside of the movable block 32, and a connecting rope 35 is installed between the fixed disk 34 and the winch 33.

[0035] When the transfer rod 12 rotates, it drives the worm wheel 29 to rotate together. The rotation of the worm wheel 29 drives the worm 30 engaged on the outside to rotate. The rotation of the worm 30 drives the capstans 33 at both ends to rotate. The rotating capstan 33 lowers the connecting rope 35, thereby moving the movable block 32 downward. The movable block 32 drives the movable block 36 to move downward, and at the same time drives the connecting frame 38 to move together through the cooperation of the cross bar 37.

[0036] The working principle of a self-cleaning hydraulic gate proposed in this embodiment is as follows:

[0037] When it is necessary to open the gate 4, first start the driving motor 6. The driving motor 6 drives the threaded rod 5 to rotate. The rotation of the threaded rod 5 drives the gate 4 connected at the bottom to move upward. The gate 4 moves upward. At the same time, the tooth groove 7 opened on the outside is engaged with the rotating gear 9. The gate 4 moves upward and drives the rotating gear 9 to rotate through the tooth groove 7. The rotation of the rotating gear 9 drives the cleaning rod 8 to rotate. The rotation of the cleaning rod 8 drives the brush 10 installed on the outside to rotate, and the brush 10 is used to clean the outer surface of the gate 4. At the same time, when the driving motor 6 is running, it drives the first pulley 14 on the outside of the threaded rod 5 to rotate together. The first pulley 14 drives the driven gear 13 to rotate through the cooperation of the first connecting belt 15. The rotation of gear 13 drives the transmission rod 12 to rotate, and the rotation of transmission rod 12 drives the brush plate 17 to rotate. The rotation of brush plate 17 breaks up and scrapes the mud, sand and gravel accumulated at the gate 4, and when the transmission rod 12 rotates, the arc gear 26 is driven to rotate through the cooperation of the second pulley 27 and the second connecting belt 28. The arc gear 26 is engaged with the rack 24 on the outer side. When the arc gear 26 rotates, it drives the rack 24 to move together. The movement of rack 24 pulls the blocking block 20 to move together through the cooperation of connecting block 22 and support rod 21 until the two blocking blocks 20 are spliced together, reducing the water flow area at the gate 4, thereby increasing the kinetic energy of water, and using the kinetic energy of water to impact the mud, sand and gravel accumulated at the gate 4. When the transmission rod 12 rotates, it drives the worm gear 29 to rotate together. The rotation of the worm gear 29 drives the worm 30 engaged on the outside to rotate. The rotation of the worm 30 drives the winches 33 at both ends to rotate. The rotating winch 33 lowers the connecting rope 35, and then drives the connecting frame 38 to move to the bottom of the canal 1 through the cooperation of the movable block 32, the moving block 36 and the cross bar 37. Under the impact of the water flow, the diversion blade 40 rotates. The rotation of the diversion blade 40 drives the first rotating rod 39 to rotate. The rotation of the first rotating rod 39 drives the second rotating rod 41 to rotate through the cooperation of the third pulley 43 and the third connecting belt 44. The rotation of the second rotating rod 41 drives the cleaning rod 42 to rotate. The rotation of the cleaning rod 42 cleans the bottom of the canal 1; the water source itself contains a high level of organic matter, microorganisms or other soluble substances. These substances may enter the canal 1 along with the water flow when the gate is opened to release water. These substances may form colloids or suspended particles in the water, thereby showing a certain degree of stickiness. When the colloids or suspended particles pass through the cleaning rod 42, the cleaning rod 42 rotates to break them up, avoiding subsequent adhesion to the inside of the canal 1, and when the first rotating rod 39 rotates, the reciprocating screw 45 is driven to rotate through the cooperation of the third connecting belt 44 and the fourth pulley 48. The rotation of the reciprocating screw 45 drives the reciprocating block 46 engaged on the outside to move, and the movement of the reciprocating block 46 drives the dispersing plate 47 to move. The movement of the dispersing plate 47 realizes the dispersing and dispersing of floating objects on the surface of the water flow, and pushes the floating objects to the banks on both sides of the canal.
