Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, and in particular to a silt removal device for water conservancy facilities. Background Art

[0002] Water conservancy facilities generally include dams, diversion channels, aqueducts, etc. or related equipment. Generally, sluice gates are installed in the water channels to regulate the water volume in sections. The opening and closing parts of the sluice gates, especially the bottom of the water-facing surface that blocks the direction of water flow, often accumulate a lot of silt composed of impurities. The silt not only affects the normal opening and closing of the sluice gates, but also blocks the waterway. Currently, the commonly distributed sluice gates are mostly vertically sliding whole-plate sluice gates. The dam body around the sluice gate is equipped with corresponding chutes on the side and bottom of the sluice gate. Some hard impurities often accumulate at the bottom of the water body. These impurities roll down into the chute of the sluice gate opening and closing with the water flow when the sluice gate is opened. When the sluice gate is closed, the water stop plate will be deformed and damaged in a non-designed direction, resulting in the side or bottom of the sluice gate body being unable to complete the sealing action. Over time, the water stop plate of the sluice gate will completely lose its water-stopping and sealing function.

[0003] The invention patent with publication number CN115874586B discloses a silt removal device for water conservancy facilities, including a sluice main body, a filter belt is provided on the water-facing side of the sluice main body, and in the normally closed state of the sluice main body, the filter belt is placed horizontally for statically receiving the stacking of silt and impurities, and the filter belt is arranged as a conveyor belt as a whole. During the upward opening process of the sluice main body, the sluice main body drives the filter belt to stand up tiltedly and block the drainage area of ​​the gate opened at the bottom; during the closing process of the sluice main body, the driving gear engages with the tooth groove section, and the filter belt is transported toward the position of the material transfer channel as a whole; the filter belt can automatically adjust its angle state according to the opening state of the sluice main body, so that silt can be accumulated in the static state of the water, and large-sized impurities can be prevented from passing through the water stop plate position during the dynamic flow of water, depending on the sluice main body. The corresponding dredging action and the protection of the water stop plate of the sluice body itself can be achieved by the opening and closing actions of the sluice body itself. The device does not take its own overall operating status into consideration during use. After the filter belt is tilted and erected, if large impurities are washed into the bottom of the filter belt by the water flow, the filter belt will not be able to be laid flat with the sluice. At the same time, the active pulley shaft will also slide and adjust in the shaft groove. When silt and other impurities accumulate in the shaft groove, the active pulley shaft will not be able to slide normally in the shaft groove, which will also affect the adjustment of the filter belt. Therefore, the device is prone to jamming and damage during actual use. When the filter belt is stuck, it will also affect the opening and closing of the sluice and water flow.

The dredging mechanism 5 can drive the control member 7 to drive the conveyor belt 6 during the process of the gate plate 2 moving down and closing, so as to remove impurities on the conveyor belt 6 at the bottom of the gate plate 2, and can cause the conveyor belt 6 to deform through the friction between the bottom of the gate plate 2 and the surface of the conveyor belt 6, thereby improving the sealing performance of the gap at the bottom of the gate plate 2.

[0031] The dredging mechanism 5 also includes a bottom plate 8 fixedly installed between the two groups of side plates 1, the bottom surface of the bottom plate 8 is in conflict with the bottom 41 of the water body, and fixed plates 9 fixedly connected to the bottom plate 8 are respectively provided on both sides of the conveyor belt 6. A driving roller 10 is rotatably connected between the two groups of fixed plates 9, and a transmission roller 11 is provided between the two groups of fixed plates 9. The outer walls of the driving roller 10 and the transmission roller 11 are both transmission-connected to the inner wall of the conveyor belt 6. A first triangular plate 38 and a second triangular plate 39 are fixedly connected between the two groups of fixed plates 9, and the bottom surfaces of the first triangular plate 38 and the second triangular plate 39 are both slidingly connected to the inner wall of the conveyor belt 6. A guide 12 is provided on the fixed plate 9 for ensuring the sealing around the conveyor belt 6 while allowing the conveyor belt 6 to be deformed during the process of being squeezed by the bottom of the gate plate 2.

[0032] The guide member 12 includes two guide blocks 13 rotatably connected to the two ends of the transmission roller 11 respectively. A guide groove 14 is provided on the fixed plate 9 and the bottom plate 8, which is horizontally slidably connected to the outer wall of the guide block 13. A return spring 15 is fixedly connected in the guide groove 14. A guide rod 16 is fixedly connected to one side of the guide block 13, and one end of the guide rod 16 is fixedly connected to the return spring 15. A slope panel 17 is fixedly connected between the two groups of guide blocks 13. One side of the slope panel 17 slides in contact with the outer wall of the conveyor belt 6, and the bottom of the slope panel 17 slides in contact with the upper side of the bottom plate 8 in the horizontal direction.

[0033] The control member 7 includes a first pulley 18 coaxially fixedly mounted on both ends of the driving roller 10, a driving wheel 19 is rotatably connected inside the fixed plate 9, the outer wall of the driving wheel 19 is evenly connected to multiple sets of ratchets 20 through the spring shaft, and the side of the driving wheel 19 is coaxially fixedly connected to a second pulley 21, the outer wall of the first pulley 18 is transmission-connected to a transmission belt 22 that is transmission-connected to the outer wall of the second pulley 21, and the driving mechanism 4 is used to link the ratchet 20 to rotate when the gate plate 2 is raised or lowered.

[0034] The guide mechanism 3 includes a support rod 23 fixedly mounted on the side panel 1, and the bottoms of the two groups of support rods 23 are fixedly connected to a conical block 40. A lifting groove 24 is provided in the support rod 23, and a lifting rod 25 is slidably connected in the vertical direction in the lifting groove 24. The upper side of the lifting rod 25 is fixedly connected to a baffle 37 slidably connected to the inner wall of the lifting groove 24. Lifting holes 26 that can be slidably connected to the outer wall of the lifting rod 25 in the vertical direction are provided on the bottom plate 8 and the fixed rod. The two sides of the gate plate 2 are respectively fixedly connected to the lifting rods 25 in the two groups of lifting grooves 24.

[0035] The driving mechanism 4 includes a rack 27 fixedly mounted on the side of the lifting rod 25. The rack 27 can engage with the ratchet 20 for driving. A threaded rod 28 is rotatably connected in the lifting groove 24. The threaded rod 28 passes through the lifting rod 25 and is threadedly connected to the lifting rod 25. The top of the support rod 23 is provided with a driving member 29 for simultaneously driving the two groups of threaded rods 28 to rotate.

[0036] The driving member 29 includes a device box 30 fixedly mounted on the top of the support rod 23. A driving motor 31 is fixedly connected to any group of the device boxes 30. The model of the driving motor 31 is preferably Y80M1-2. The output end of the driving motor 31 is coaxially fixedly connected to the driving shaft 32. Two groups of worm gears 33 are coaxially fixedly connected to the driving shaft 32. The two groups of worm gears 33 are respectively located in the device boxes 30 on both sides. The top of the threaded rod 28 is coaxially fixedly connected to a first gear 34. A second gear 35 meshing with the first gear 34 is rotatably connected in the device box 30. A worm wheel 36 meshing with the worm 33 is coaxially fixedly connected to the second gear 35.

[0037] In this embodiment, the driving motor 31 drives the driving shaft 32 to rotate, and the driving shaft 32 drives the worm gears 33 on both sides to rotate, thereby causing the worm gear 36 to rotate, driving the second gear 35 to drive the first gear 34 to rotate, and the first gear 34 drives the threaded rod 28 to rotate, so that the lifting rods 25 on both sides can synchronously drive the gate plate 2 to lift and open and close. During the opening and closing process, the lifting rods 25 on both sides will always slide in the lifting groove 24, and the bottom end side of the support rod 23 is in a closed state and directly inserted into the bottom 41 of the water body for fixation. Only the lifting grooves 24 located on both sides of the gate plate 2 are connected to the water body, but in the process of lifting and lowering the gate plate 2, the length of the lower end of the lifting rod 25 is longer, which can ensure that when the gate plate 2 is fully opened, the lifting rod 25 can always block the side of the lifting groove 24 to prevent impurities from entering the lifting groove 24.

[0038] At the same time, when the gate plate 2 follows the lifting and lowering of the lifting rod 25, the lifting rod 25 will push the upper baffle 37 to rise and fall synchronously, thereby continuously blocking the lifting groove 24 in the upper area of ​​the lifting rod 25, preventing the water on the upper side from driving impurities into the lifting groove 24 and affecting the stable lifting state of the lifting rod 25, thereby ensuring that the gate plate 2 can continue to open and close smoothly. The setting of the lifting groove 24 also ensures the sealing between the two sides of the gate plate 2 and the support rod 23, thereby preventing water from overflowing from the gaps on both sides during the closing process.

[0039] When the gate 2 is in the process of moving down and closing, the lifting rod 25 drives the rack 27 on the side to move down, and the rack 27 drives the ratchet 20 to rotate, so that the driving wheel 19 rotates, and the driving wheel 19 drives the second pulley 21 to rotate, thereby driving the first pulley 18 and the driving roller 10 to rotate through the transmission belt 22, and the driving roller 10 drives the upper side of the conveyor belt 6 to the side of the transmission roller 11 for transmission and transportation, thereby pushing the impurities on the conveyor belt 6 at the bottom of the gate 2 to the side of the transmission roller 11. The belt 6 is output from the upper side of the bottom plate 8 at the driving roller 10. At this time, the surface of the conveyor belt 6 is relatively clean. When the gate is closed, the bottom surface of the gate plate 2 will fit with the relatively clean surface of the conveyor belt 6 and squeeze the middle part of the conveyor belt 6 to move downward until the upper and lower layers of the conveyor belt 6 fit together, that is, the gate closing is completed. At this time, since the conveyor belt 6 at the bottom of the gate plate 2 is made of corrosion-resistant material and has a certain elasticity, it is ensured that it can fully contact the bottom surface of the gate plate 2 when the gate plate 2 is closed, thereby achieving a better sealing effect.

[0040] When the gate 2 pushes the middle part of the conveyor belt 6 downward, since the position of the driving roller 10 is relatively fixed, the transmission roller 11 will be pulled to slide toward the side of the driving roller 10, and the guide blocks 13 on both sides of the transmission roller 11 will slide horizontally in the guide groove 14, driving the guide rod 16 to squeeze the return spring 15. At this time, the guide block 13 will close the guide groove 14, and the two sides of the conveyor belt 6 will be respectively fitted with the fixed plate 9. Water and impurities will not enter the guide groove 14 or the bottom of the conveyor belt 6, achieving a better sealing function, preventing impurities from entering the device and affecting the normal and continuous operation of the equipment. In the process of sliding of the guide block 13, the middle ramp panel 17 will also be driven to slide synchronously, so that one side of the ramp panel 17 can always fit with the outer wall of the conveyor belt 6, thereby scraping off the impurities transmitted on the conveyor belt 6. The movement of the ramp panel 17 also ensures that when the conveyor belt 6 moves, impurities will not fall into the original position of the transmission roller 11, so that when resetting, the transmission roller 11 can better slide back to the initial position to prevent the equipment from getting stuck.

[0041] When the gate 2 is moved up and opened, the pressure of the bottom of the gate 2 on the conveyor belt 6 is reduced, and the reset spring 15 rebounds, pushing the guide rod 16 and the guide block 13 to slide in the opposite direction in the guide groove 14, thereby driving the transmission roller 11 to slide and reset, and supporting the conveyor belt 6 to a horizontal state. The elastic force of the reset spring 15 is relatively large, and the conveyor belt 6 can always be kept in a taut state, ensuring that the driving roller 10 can drive the conveyor belt 6 to convey, and at the same time, it can also push a certain mass of impurities on the conveyor belt 6 to be lifted and conveyed, and will only be slightly compressed when the gate 2 is pressed down.

[0042] During the upward movement of the gate plate 2 and the lifting rod 25, the rack 27 moves upward in the opposite direction. At this time, the teeth of the rack 27 will slide against the arc surface of the ratchet 20, pushing the ratchet 20 to swing toward the side of the driving wheel 19, thereby failing to drive the ratchet 20 to rotate. In other words, during the opening process, even if there are accumulated impurities on the conveyor belt 6, it will not affect the opening of the gate plate 2. At this time, there is no need to drive the conveyor belt 6 for transmission, which also avoids useless work to a certain extent and saves energy.

[0043] When installing the dredging device as a whole, it is only necessary to fix the bottom plate 8 and the conveyor belt 6 as a whole to the bottom 41 of the water body, and at the same time insert the support rods 23 on both sides into the bottom 41 of the water body and fix them, install the sealed side plates 1 on both sides of the water body, and then fix the gate plate 2 to the lifting rods 25 on both sides to complete the installation. The operation is convenient, and there will be no large-scale water seepage inside the entire equipment. The sealing performance is good, which can prevent large impurities from entering the interior of the equipment or the bottom end of the gate plate 2 to avoid affecting the normal operation of the equipment. The structure is stable and the operation is convenient.

[0044] It is worth noting that the guide member 12 in the present device can be removed, and the two ends of the transmission roller 11 can be directly fixed and rotated, and a support plate is set on the inner wall of the conveyor belt 6. At this time, the gate plate 2 moves down and directly drives the conveyor belt 6 for horizontal transmission. When the bottom of the gate plate 2 collides with the top surface of the conveyor belt 6, the gate is closed. However, at this time, the conveyor belt 6 at the bottom of the gate plate 2 has only one layer, and there will be a certain gap between the lower conveyor belt 6 and the bottom plate 8. At this time, part of the water flow will flow through the gap at the bottom, and the sealing performance is relatively poor. Therefore, a guide member 12 is set to squeeze and close the double-layer conveyor belt 6 to improve the overall sealing performance of the equipment.
