Description

Technical Field

[0001] The present invention relates to the technical field of energy dissipation basins, and in particular to an energy dissipation basin with a sedimentation and purification structure. Background Art

[0002] The channel water diversion outlet is an important building for water volume distribution and scheduling of the irrigation area's water conveyance channel. In actual operation, the water conveyance system distributes the flow according to the water demand and adjustable water volume, and controls and schedules through the check gate and the diversion gate, and conveys the distributed water volume to the irrigation location.

[0003] In water conservancy irrigation treatment, the main channel controls the diversion of water through the gate opening. In order to reduce the flow velocity of the water diverted from the main channel and reduce the damage to the field when the water enters the field, an energy dissipation basin will be set at the diversion position of the main channel to weaken the energy of the water flow and reduce the water flow velocity. However, in the water flow transportation of the main channel, a large amount of sediment will be mixed in the water flow. In the prior art, after the water flow velocity in the energy dissipation basin is lower, the sediment will settle at the bottom of the energy dissipation basin, and the gradually deposited sediment will reduce the depth of the energy dissipation basin and at the same time reduce the energy dissipation effect of the energy dissipation basin.

[0023] In summary, the present invention has the following beneficial technical effects: The present invention provides an energy dissipation and sand collecting structure, an end block, an outer cylinder, a water receiving plate and other components. After the water flow enters the pool body, the water flow impacts the energy dissipation and sand collecting structure, and the water flow drives the sediment to enter the energy dissipation and sand collecting structure through the opening. The water flow impacts the water receiving plate to drive the longitudinal axis to rotate. The longitudinal axis can drive the outer cylinder to rotate through the bevel gear transmission structure, and the outer cylinder drives the energy dissipation and sand collecting structure to rotate. After the energy dissipation and sand collecting structure rotates to the upper side of the outer cylinder, the sand in the energy dissipation and sand collecting structure enters the sand discharge cylinder through the opening of the sand discharge cylinder, so that the sediment in the water flow will not continue to accumulate inside the pool body.

[0024] The present invention is provided with components such as a linkage plate, a permeable sand retaining plate, a vertical pole and a reducing ring. The vertical pole is in contact with the outer ring surface of the reducing ring under elastic connection with the permeable box plate. When the outer cylinder drives the permeable box plate to rotate, the vertical pole is driven to slide on the outer ring surface of the reducing ring. When the vertical pole moves to the large diameter part of the reducing ring, the vertical pole pushes the linkage plate through the pressure plate to drive the long axis and the permeable sand retaining plate to rotate, so that the permeable sand retaining plate rotates to contact the permeable sand sliding plate, and then the permeable sand retaining plate, the permeable sand sliding plate and the side permeable plate form a closed space, so that when the permeable box plate rotates, the mud and sand inside will not be thrown into the pool body from the sand inlet.

[0025] In the present invention, by providing components such as a short shaft, an inner rib groove, and an outer rib sleeve, when there is less sediment in the water-permeable tank plate, the end block drives the inner rib groove of the short shaft to disengage from the outer rib sleeve under the push of the elastic spring, and the outer cylinder does not rotate. The water flow impacts the water-permeable tank plate to generate a pulling force. As the sediment accumulates in the water-permeable tank plate, the water permeability of the water-permeable tank plate decreases, increasing the pulling force generated by the water flow on the water-permeable tank plate. The inner rib groove of the short shaft is pulled to sleeve on the surface of the outer rib sleeve, enabling the longitudinal shaft to drive the outer cylinder and the water-permeable tank plate to rotate during rotation, preventing the water-permeable tank plate from continuously rotating and reducing the sediment collection, so that the outer cylinder will rotate only after a certain amount of sediment is collected inside the water-permeable tank plate.

[0026] In the present invention, by providing an elastic dial and an elastic push plate, when the bevel gear combination shaft meshes with the bevel gear cylinder, and the bevel gear cylinder applies a thrust to the elastic push plate through the elastic dial to drive the outer cylinder to rotate, when the vertical rod rotates to the position where the variable-diameter ring protrudes, the water-permeable tank plate is in an inclined state and communicates with the opening of the sand discharge cylinder. The elastic dial is misaligned with the elastic push plate through deformation, and the water-permeable tank plate rotates downward to reset under gravity. Then, when the elastic dial applies a thrust to the next elastic push plate again, the water-permeable tank plate rotates again. The reciprocating swing of the water-permeable tank plate increases the speed at which the sediment in the water-permeable tank plate falls into the sand discharge cylinder, preventing the sediment from adhering to the inside of the water-permeable tank plate.

Detailed Implementation Manner

[0029] The following further elaborates on the present invention in conjunction with the attached Figures 1-9 drawings.

[0030] An embodiment of the present invention discloses an energy dissipation pool with a sedimentation and purification structure. As Figures 1-9 shown, it includes a pool body 1. One end of the pool body 1 is connected to the main channel through a sluice gate. By controlling the opening and closing of the sluice gate, the water flow can be controlled to enter the pool body 1. A longitudinal axis 2 is rotatably inserted inside the pool body 1. A plurality of water receiving plates 3 are fixedly sleeved at one end of the longitudinal axis 2 inside the pool body 1. A water guiding plate is installed on one side of the pool body 1 close to the main channel, so that the water flow passes under the longitudinal axis 2. The water flow drives the longitudinal axis 2 to rotate by pushing the water receiving plates 3 to rotate.

[0031] An energy dissipation and sediment collection structure 4 that can permeate water is arranged inside the pool body 1. The energy dissipation and sediment collection structure 4 is located on the left side of the water receiving plates 3. One side of the energy dissipation and sediment collection structure 4 close to the longitudinal axis 2 is open. The water flow drives the sediment to enter the inside of the energy dissipation and sediment collection structure 4 through the opening of the energy dissipation and sediment collection structure 4, separating the sediment in the water. The water flow can pass through the energy dissipation and sediment collection structure 4. The energy dissipation and sediment collection structure 4 reduces the energy of the water flow by blocking the water flow.

[0032] An outer cylinder 6 is connected and installed at the upper end of the energy dissipation and sediment collection structure 4.

[0033] The energy dissipation and sediment collection structure 4 includes a permeable water tank plate 41. The upper end of the permeable water tank plate 41 penetrates and is installed on the bottom surface of the outer cylinder 6. A plurality of permeable sand sliding plates 42 are fixed on one side of the permeable water tank plate 41 close to the longitudinal axis 2. Sand inlets 43 are opened on one side of the permeable water tank plate 41 close to the longitudinal axis 2 and above the lower end of each permeable sand sliding plate 42. When the water flow is flowing, it drives the sediment to enter the permeable water tank plate 41 through the sand inlets 43. The water flows out of the permeable water tank plate 41, leaving the sediment in the permeable water tank plate 41. The water flow is blocked inside the permeable water tank plate 41, reducing the speed of the water flow.

[0034] A sand discharge cylinder 7 is rotatably and coaxially inserted inside the outer cylinder 6. The upper surface of the sand discharge cylinder 7 is open. When the permeable water tank plate 41 rotates to the upper side of the sand discharge cylinder 7, the sediment inside the permeable water tank plate 41 can fall into the sand discharge cylinder 7 through the upper opening of the sand discharge cylinder 7. The rear end of the sand discharge cylinder 7 is open, and the sediment inside the sand discharge cylinder 7 can be discharged from the rear opening. A spiral sand delivery plate 71 is rotatably inserted inside the sand discharge cylinder 7. A transmission shaft 72 is fixedly inserted at the axis of the spiral sand delivery plate 71. The front end of the transmission shaft 72 rotatably penetrates through the front inner wall of the sand discharge cylinder 7. When the spiral sand delivery plate 71 rotates, it can push the sediment inside the sand discharge cylinder 7. The rear end of the sand discharge cylinder 7 is slidably connected to the upper surface of the pool body 1.

[0035] A permeable sand retaining plate 44 is provided on one side of the permeable water tank plate 41 close to the longitudinal axis 2 and above each permeable sand sliding plate 42. A convex strip 421 is fixed on the upper surface of the permeable sand sliding plate 42. When the permeable sand retaining plate 44 rotates, it will contact the convex strip 421. When the permeable sand retaining plate 44 and the convex strip 421 contact the permeable sand sliding plate 42 at the same time, side permeable plates 422 are fixed at both the front and rear ends of the permeable sand sliding plate 42. The side permeable plates 422 are fixed to the permeable water tank plate 41. When the permeable sand retaining plate 44 rotates to contact the permeable sand sliding plate 42, a closed permeable space is formed with the two side permeable plates 422, so that when the permeable water tank plate 41 rotates upward, the sediment will not fall back into the pool body 1. The front end of the permeable water tank plate 41 is cavity-shaped. The upper surface of the permeable sand sliding plate 42 is arranged at an acute angle with the permeable water tank plate 41. The permeable sand sliding plate 42 and the permeable sand retaining plate 44 have the same length. When the water drives the sediment to flow, it is drained through the acutely arranged permeable sand sliding plate 42 and enters the permeable water tank plate 41 through the sand inlet 43.

[0036] A long shaft 45 is fixed to the upper end of the permeable sand retaining plate 44. The long shaft 45 is rotatably connected to the permeable water tank plate 41. The front end of the long shaft 45 is located inside the cavity of the permeable water tank plate 41. The long shaft 45 is elastically connected to the permeable water tank plate 41. The elastic connection between the long shaft 45 and the permeable water tank plate 41 has a tendency to drive the permeable sand retaining plate 44 to contact the permeable water tank plate 41. A linkage plate 46 is fixedly sleeved on the long shaft 45 inside the cavity-shaped structure of the permeable water tank plate 41. A vertical rod 47 slidably penetrates through the inner top wall of the cavity-shaped structure of the permeable water tank plate 41. The lower end of the vertical rod 47 is elastically connected to the permeable water tank plate 41. A pressing plate 48 is fixed on one side of the vertical rod 47 close to the long shaft 45 and above each linkage plate 46.

[0037] A variable diameter ring 49 is rotatably sleeved coaxially at one end in front of the permeable water tank plate 41 on the outer surface of the outer cylinder 6. The upper end of the vertical rod 47 is in sliding contact with the circumferential surface of the variable diameter ring 49.

[0038] A end block 8 is rotatably sleeved at the front end of the outer cylinder 6. The variable-diameter ring 49 is fixed to the end block 8. The circumferential surface of the variable-diameter ring 49 is divided into a large-diameter range and a small-diameter range. The connection between the small-diameter end and the large-diameter end on the lower side of the variable-diameter ring 49 is an inclined surface. The outer ring surface of the large-diameter end on the upper side of the variable-diameter ring 49 is convex. When the angle between the right side surface of the water-permeable tank plate 41 and the vertical surface of the outer cylinder 6 is less than 45 degrees, the vertical rod 47 is located in the small-diameter part of the variable-diameter ring 49. During the upward rotation of the water-permeable tank plate 41, the vertical rod 47 gradually rotates from the small-diameter part of the variable-diameter ring 49 to the large-diameter part of the variable-diameter ring 49. When the vertical rod 47 rotates from the small-diameter part of the variable-diameter ring 49 to the large-diameter part, it pushes the vertical rod 47 to slide within the water-permeable tank plate 41, and through the pressing plate 48, it pushes the linkage plate 46 to rotate, and then drives the water-permeable sand-blocking plate 44 to rotate to contact the convex strip 421 through the long shaft 45.

[0039] The lower end of the end block 8 is elastically and slidably connected to the upper surface of the pool body 1.

[0040] A double-rod frame 9 is fixedly installed on the upper surface of the pool body 1. The end block 8 is slidably sleeved on the outer surface of the double-rod frame 9. An elastic spring 10 is fixed to one end of the double-rod frame 9 away from the longitudinal axis 2. The other end of the elastic spring 10 is fixed to the double-rod frame 9. The elastic spring 10 is slidably sleeved on the outer surface of the double-rod frame 9. The elastic spring 10 limits the initial position of the end block 8 on the double-rod frame 9. As the sediment in the water-permeable tank plate 41 increases, the gravity of the sediment on the water-permeable tank plate 41 increases, and the water permeability of the water-permeable tank plate 41 decreases. When the water flow impacts the water-permeable tank plate 41, the water-permeable tank plate 41 has a tendency to pull the end block 8 to compress the elastic spring 10.

[0041] A bevel gear transmission structure 5 is installed on the front side of the pool body 1. The bevel gear transmission structure 5 is connected to the front end of the longitudinal axis 2. The front end of the outer cylinder 6 is connected to the bevel gear transmission structure 5. The torque of the longitudinal axis 2 is transmitted to the outer cylinder 6 through the bevel gear transmission structure 5.

[0042] The bevel gear transmission structure 5 includes a horizontal axis 51. The longitudinal axis 2 is in transmission connection with the horizontal axis 51 through a bevel gear transmission box 58. Two meshing bevel gears are arranged in the bevel gear transmission box 58. The longitudinal axis 2 drives the horizontal axis 51 to rotate through the two meshing bevel gears. The horizontal axis 51 is rotatably installed on the front surface of the pool body 1.

[0043] A bevel gear cylinder 52 is installed at the front end of the outer cylinder 6, and a bevel gear combination shaft 53 is meshed with the front side of the bevel gear cylinder 52. The bevel gear cylinder 52 is rotatably sleeved on the outer surface of the outer cylinder 6. A plurality of evenly distributed elastic pick plates 521 are fixed to the inner ring surface of the bevel gear cylinder 52. A plurality of elastic push plates 522 are fixed to the circumferential side surface of the outer cylinder 6 located on the inner side of the bevel gear cylinder 52. The number of elastic push plates 522 is equal to the number of elastic pick plates 521. The plurality of elastic push plates 522 and the plurality of elastic pick plates 521 are alternately distributed. When the bevel gear cylinder 52 rotates, the elastic pick plates 521 are driven to apply thrust to the elastic push plates 522. When the vertical rod 47 and the protrusion of the reducer ring 49 are After the outer cylinder 6 is in contact with the shape, the outer cylinder 6 can no longer rotate. At this time, the upper end of the water-permeable box plate 41 is located at the left side of the lower end and is tilted. At this time, the water-permeable box plate 41 is connected to the opening of the sand-discharging cylinder 7, and passes through when the bevel gear cylinder 52 continues to rotate. The elastic pick plate 521 is misaligned with the elastic push plate 522 through deformation, and the water-permeable box plate 41 is reset and rotated downward under gravity. Then, when the elastic pick plate 521 and the next elastic push plate 522 apply thrust again, the water-permeable box plate 41 rotates again. The reciprocating swing of the water-permeable box plate 41 increases the speed at which the sediment in the water-permeable box plate 41 falls into the sand-discharging cylinder 7, thereby preventing the sediment from adhering to the inside of the water-permeable box plate 41.

[0044] The bevel gear combination shaft 53 is rotationally connected to the end block 8. The bevel gear combination shaft 53 is composed of a shaft rod and a plurality of coaxially arranged bevel gears. The transmission shaft 72 is located in front of the sand discharge cylinder 7 and is coaxially fixed with a meshing bevel gear 73 at one end. The meshing bevel gear 73 meshes with a bevel gear of the bevel gear combination shaft 53. When the bevel gear combination shaft 53 rotates, the transmission shaft 72 can be driven to rotate by meshing with the meshing bevel gear 73.

[0045] A force storage elastic plate 11 is provided on the side of the end block 8 away from the longitudinal axis 2. The lower end of the force storage elastic plate 11 is elastically connected to the upper surface of the pool body 1 for unidirectional rotation. The force storage elastic plate 11 rotates unidirectionally toward the longitudinal axis 2. There is a gap between the bottom surface of the end block 8 and the upper surface of the pool body 1. When the permeability of the permeable box plate 41 is reduced and the water flow impacts the permeable box plate 41 to pull the end block 8 to compress the elastic spring 10, the force storage elastic plate 11 first applies resistance to the movement of the end block 8 to prevent the end block 8 from moving when the sediment inside the permeable box plate 41 starts to increase, causing the permeable box plate 41 to rotate when the sediment collected in the permeable box plate 41 is small. When the permeable box plate 41 rotates frequently, the collection efficiency is low. When enough sediment is collected in the permeable box plate 41, the end block 8 is gradually impacted by the water flow, and the force storage elastic plate 11 elastically deforms, so that the end block 8 can move to the other side of the force storage elastic plate 11.

[0046] A transmission bevel gear 54 meshes with the lower side of the bevel gear combination shaft 53. A short shaft 55 is installed at the axis of the transmission bevel gear 54. The short shaft 55 is slidably sleeved on the outer surface of the transverse shaft 51. Outer edge sleeves 56 are fixedly sleeved on the outer surface of the transverse shaft 51 on the left side of each short shaft 55. The multiple outer edge sleeves 56 and the multiple transmission bevel gears 54 are staggered. An inner edge groove 57 adapted to the outer edge sleeve 56 is opened inside the left end of the short shaft 55. After the end block 8 moves to the other side of the energy storage elastic plate 11, the impact of the water flow can drive the inner edge groove 57 of the short shaft 55 to be sleeved on the surface of the outer edge sleeve 56. At this time, when the transverse shaft 51 rotates, it can drive the short shaft 55 to rotate. Then, through the meshing of the bevel gear combination shaft 53 and the transmission bevel gear 54, the bevel gear cylinder 52 and the meshing bevel gear 73 can be driven to rotate. After the sediment in the water permeable tank plate 41 decreases, the end block 8 is reset under the push of the elastic spring 10, so that the inner edge groove 57 of the short shaft 55 is disengaged from the outer edge sleeve 56. Then, the water permeable tank plate 41 falls downward under gravity and re-enters the pool body 1 to dissipate energy and collect sediment, preventing sediment from accumulating in the pool body 1 all the time.

[0047] The working principle is as follows: Open the sluice to divert the water flow in the main channel into the pool body 1. The water flow drives the longitudinal shaft 2 to rotate by impacting the water receiving plate 3. The energy dissipation and sediment collection structure 4 generates resistance to the flow of the water flow, reduces the kinetic energy of the water flow, and dissipates the energy of the water flow. The water flow drives the sediment to enter the energy dissipation and sediment collection structure 4 through the opening. The longitudinal shaft 2 can drive the outer cylinder 6 to rotate through the bevel gear transmission structure 5. The outer cylinder 6 drives the energy dissipation and sediment collection structure 4 to rotate. After the energy dissipation and sediment collection structure 4 rotates to the upper side of the outer cylinder 6, the sand in the energy dissipation and sediment collection structure 4 enters the sand discharge cylinder 7 through the opening of the sand discharge cylinder 7, effectively preventing sediment from accumulating in the pool body 1 all the time. The sediment entering the sand discharge cylinder 7 can be discharged from the rear end.

[0048] The above are all the preferred embodiments of the present invention. The protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
