Description

Technical Field

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

[0002] Water conservancy facilities generally include dams, diversion channels, aqueducts, etc. or related equipment. Generally, sluice gates for segmentally regulating water volume are installed at water channels. At the opening and closing part of the sluice gate, especially at the bottom of the water-facing surface that blocks the water flow direction, a lot of silt composed of impurities often accumulates. The silt not only affects the normal opening and closing of the sluice gate but also blocks the water channel. Currently, most of the commonly distributed sluice gates are integral plate sluice gates that open and close vertically and slide. Corresponding chutes are provided on the side and bottom of the dam body around the sluice gate corresponding to the side and bottom of the sluice gate. Some hard impurities often accumulate at the bottom of the water body. These impurities roll into the chute where the sluice gate opens and closes along with the flowing water 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 edge 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 stop and sealing function.

[0003] The invention patent with the publication number CN115874586B discloses a silt cleaning device for water conservancy facilities, which includes a sluice gate body. A filter belt is provided on one side of the water-facing surface of the sluice gate body. In the normally closed state of the sluice gate body, the filter belt is placed horizontally for statically receiving the stacking of silt impurities. The filter belt is integrally set in the form of a conveyor belt. During the process of the sluice gate body opening upwards, the sluice gate body drives the filter belt to tilt and stand up to block the drainage area of the bottom opened sluice opening; during the process of the sluice gate body closing, the driving gear meshes with the tooth groove section, and the filter belt is integrally conveyed towards the position of the feeding channel; through the provided filter belt, the angle state can be automatically adjusted according to the opening state of the sluice gate body, which can not only stack silt in the static water but also prevent large-sized impurities from passing through the position of the water stop plate during the dynamic flow of water. Relying on the opening and closing actions of the sluice gate body itself can realize the corresponding silt cleaning actions and the protection of the water stop plate of the sluice gate body itself during the silt cleaning process. However, the overall operating state of the device itself is not considered during the use process. After the filter belt tilts and stands up, if large-sized impurities are washed into the bottom of the filter belt by the water flow, then the filter belt cannot be laid flat along with the sluice gate at this time. At the same time, the driving pulley shaft will also slide and adjust in the shaft chute. When silt and other impurities accumulate in the shaft chute, it will also cause the driving pulley shaft to be unable to slide normally in the shaft chute, 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 gets jammed, it will also affect the opening and closing of the sluice gate and the water flow transportation. Summary of the Invention

Detailed implementation mode

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-11 , the present invention provides a technical solution: a silt cleaning device for water conservancy facilities, including a guiding mechanism 3, a driving mechanism 4, a silt cleaning mechanism 5 and two side plates 1 respectively fixedly installed on both sides of the water body. A gate plate 2 is arranged between the two side plates 1. The guiding mechanism 3 is installed on the two side plates 1 to guide both sides of the gate plate 2 and prevent impurities from hindering the lifting of the gate plate 2. The driving mechanism 4 is installed on the side plate 1 to drive the gate plate 2 to lift and open. The silt cleaning mechanism 5 includes a conveyor belt 6 installed between the two side plates 1. A control part 7 for driving the conveyor belt 6 to transmit during the lifting of the gate plate 2 is arranged on the side plate 1. The silt cleaning mechanism 5 can drive the control part 7 during the downward movement and closing of the gate plate 2 to make the conveyor belt 6 transmit, move the impurities on the conveyor belt 6 at the bottom of the gate plate 2, and can make the conveyor belt 6 deform by the contact between the bottom of the gate plate 2 and the surface of the conveyor belt 6, improving the sealing performance at the gap at the bottom of the gate plate 2.

[0020] The dredging mechanism 5 further includes a bottom plate 8 fixedly installed between the two side plates 1. The bottom surface of the bottom plate 8 abuts against the bottom 41 of the water body. 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 fixed plates 9. A transmission roller 11 is provided between the two fixed plates 9. The outer walls of the driving roller 10 and the transmission roller 11 are both drivingly 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 fixed plates 9. The bottom surfaces of the first triangular plate 38 and the second triangular plate 39 are both slidably connected to the inner wall of the conveyor belt 6. A guiding member 12 is provided on the fixed plate 9 for ensuring the sealing around the conveyor belt 6 while enabling the conveyor belt 6 to deform during the process of being squeezed by the bottom of the gate plate 2.

[0021] The guiding member 12 includes two guiding blocks 13 respectively rotatably connected to both ends of the transmission roller 11. Guiding grooves 14 for slidably connecting the outer walls of the guiding blocks 13 in the horizontal direction are formed on the fixed plate 9 and the bottom plate 8. A return spring 15 is fixedly connected in the guiding groove 14. A guiding rod 16 is fixedly connected to one side of the guiding block 13. One end of the guiding rod 16 is fixedly connected to the return spring 15. A slope plate 17 is fixedly connected between the two guiding blocks 13. One side of the slope plate 17 is slidably attached to the outer wall of the conveyor belt 6. The bottom of the slope plate 17 is slidably attached to the upper side of the bottom plate 8 in the horizontal direction.

[0022] The control member 7 includes first belt pulleys 18 coaxially and fixedly installed at both ends of the driving roller 10. A driving wheel 19 is rotatably connected inside the fixed plate 9. Multiple ratchet teeth 20 are evenly rotatably connected to the outer wall of the driving wheel 19 through a winding shaft. A second belt pulley 21 is coaxially and fixedly connected to the side surface of the driving wheel 19. A transmission belt 22 drivingly connected to the outer wall of the second belt pulley 21 is drivingly connected to the outer wall of the first belt pulley 18. The driving mechanism 4 is used to drive the ratchet teeth 20 to rotate when the gate plate 2 moves up and down.

[0023] The guiding mechanism 3 includes support rods 23 fixedly installed on the side plates 1. Tapered blocks 40 are fixedly connected to the bottoms of the two support rods 23. A lifting groove 24 is formed in the support rod 23. A lifting rod 25 is slidably connected in the lifting groove 24 in the vertical direction. A baffle 37 slidably connected to the inner wall of the lifting groove 24 is fixedly connected to the upper side of the lifting rod 25. Lifting holes 26 capable of slidably connecting the outer wall of the lifting rod 25 in the vertical direction are formed 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 lifting grooves 24.

[0024] The driving mechanism 4 includes a rack 27 fixedly installed on the side surface of the lifting rod 25. The rack 27 can be engaged with the ratchet teeth 20 for driving. A threaded rod 28 is rotatably connected in the lifting groove 24. The threaded rod 28 penetrates through the lifting rod 25 and is threadedly connected to the lifting rod 25. A driving member 29 for simultaneously driving the two threaded rods 28 to rotate is provided at the top of the support rod 23.

[0025] The driving member 29 includes a device box 30 fixedly installed at the top end of the support rod 23. A driving motor 31 is fixedly connected inside any one set of device boxes 30. The model of the driving motor 31 is preferably Y80M1-2. The output end of the driving motor 31 is coaxially and fixedly connected with a driving shaft 32. Two sets of worm gears 33 are coaxially and fixedly connected to the driving shaft 32. The two sets of worm gears 33 are respectively located inside the device boxes 30 on both sides. The top end of the threaded rod 28 is coaxially and fixedly connected with a first gear 34. A second gear 35 meshing with the first gear 34 is rotatably connected inside the device box 30. A worm wheel 36 meshing with the worm gear 33 is coaxially and fixedly connected to the second gear 35.

[0026] In this implementation scheme, the driving motor 31 drives the driving shaft 32 to rotate. The driving shaft 32 drives the worm gears 33 on both sides to rotate, so that the worm wheel 36 rotates, driving the second gear 35 to drive the first gear 34 to rotate. The first gear 34 drives the threaded rod 28 to rotate, so that the lifting rods 25 on both sides can synchronously drive the sluice gate 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 grooves 24. The bottom side of the support rod 23 is in a closed state and is directly inserted into the bottom 41 of the water body for fixation. Only the lifting grooves 24 located on both sides of the sluice gate 2 are connected to the water body. However, during the lifting process of the sluice gate 2, the length of the lower end of the lifting rod 25 is relatively long, which can ensure that when the sluice gate 2 is fully opened, the lifting rod 25 can always block the side surface of the lifting groove 24 to prevent impurities from entering the lifting groove 24.

[0027] At the same time, during the process of the sluice gate 2 following the lifting rod 25 to lift, the lifting rod 25 will push the upper baffle 37 to lift synchronously, so as to continuously block the lifting groove 24 in the area above the lifting rod 25, preventing the water body above from driving impurities into the lifting groove 24 and affecting the stable lifting state of the lifting rod 25, ensuring that the sluice gate 2 can continue to open and close smoothly. The setting of the lifting groove 24 also ensures the sealing performance between both sides of the sluice gate 2 and the support rod 23, preventing the water body from overflowing from the gaps on both sides during the process of closing the sluice.

[0028] When the gate plate 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 plate 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 closing the gate, 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 each other, 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 when the gate plate 2 is closed, it can fully contact with the bottom surface of the gate plate 2 to achieve a better sealing effect.

[0029] When the gate plate 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 reset 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 fit with the fixed plate 9 respectively. 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.

[0030] When the gate 2 is moved open, 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 to ensure that the driving roller 10 can drive the conveyor belt 6 to transport. At the same time, it can also push a certain mass of impurities on the conveyor belt 6 to be lifted and transported, and only a small compression will be performed when the gate 2 is pressed down.

[0031] 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 towards the driving wheel 19 side, thus preventing the ratchet 20 from rotating. That is to say, during the process of opening the gate, 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 to transmit, which also avoids doing useless work to a certain extent and saves energy.

[0032] When the whole dredging device is installed, only the bottom plate 8 and the conveyor belt 6 need to be fixed to the bottom 41 of the water body as a whole. At the same time, the two side support rods 23 are inserted into the bottom 41 of the water body and fixed. The sealed side plates 1 are installed on both sides of the water body, and then the gate plate 2 is fixed to the two side lifting rods 25, and the installation can be completed. The operation is convenient, and there will be no large-area water seepage inside the whole device. The sealing performance is good, which can prevent large impurities from entering the inside of the device or the bottom end of the gate plate 2, avoiding affecting the normal operation of the device. The structure is stable and the operation is convenient.

[0033] It should be noted that the guiding member 12 in this device can be removed. The two ends of the driving roller 11 are directly fixed and rotated, and a support plate is arranged on the inner wall of the conveyor belt 6. At this time, after the gate plate 2 moves downward, it directly drives the conveyor belt 6 to perform horizontal transmission. When the bottom of the gate plate 2 touches the top surface of the conveyor belt 6, the gate closing is completed. However, at this time, the number of layers of the conveyor belt 6 at the bottom of the gate plate 2 is one layer, and there will still be a certain gap between the lower conveyor belt 6 and the bottom plate 8. At this time, a part of the water flow will flow through the bottom gap, and the sealing performance is relatively poor. Therefore, the guiding member 12 is set to squeeze and close the double-layer conveyor belt 6 to improve the overall sealing performance of the device.

[0034] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0035] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
