Description

Technical Field

[0001] This application relates to the technical field of water conservancy projects, and particularly relates to a silt cleaning device for water conservancy project sluice gates. Background Art

[0002] Silt is cohesive soil deposited in a static or slow-flowing water environment and formed through biochemical processes. Modern sediments are formed under the condition of microbial participation. They are rich in organic matter and usually appear grayish-black. In water conservancy projects, silt usually hinders the construction process, thus requiring a silt cleaning device to remove the silt.

[0003] Regarding the above related technologies, most of the existing silt cleaning devices for water conservancy projects use a bucket to shovel out the silt and collect it in a silt collection box, and then squeeze it in the silt collection box to separate the silt from the water. The work of collecting silt and squeezing silt cannot be carried out simultaneously, which takes a long time and has low efficiency. Summary of the Invention

[0004] In order to carry out the work of silt collection and silt squeezing simultaneously, reduce the time consumed for silt cleaning, and improve work efficiency, this application provides a silt cleaning device for water conservancy project sluice gates.

[0011] A water collection component, which is installed in the device housing and is used for collecting the water in the silt;

[0012] Among them, the silt collection component includes:

[0013] A silt collection box, which is fixedly installed in the device housing, and both the silt pumping component and the water collection component are connected to the silt collection box;

[0022] By adopting the above technical solutions, when a silt cleaning device for a water conservancy project sluice works, the driving wheel rotates to drive the device housing to move. While the device housing moves, the shovel bucket gathers the silt in the shovel bucket, and the silt pumping assembly pumps the silt into the silt accumulation assembly. While the silt enters the silt accumulation assembly, the silt accumulation assembly squeezes the silt. When the silt accumulation assembly works, the silt pumping assembly first pumps part of the silt into the space formed between the first extrusion plate and the bottom of the silt accumulation tank. Then the first motor works and drives the rotating shaft to rotate. The rotating shaft rotates to drive the first rotating rod to rotate. While the first rotating rod rotates, it slides in the first threaded groove, thereby driving the first sleeve to move towards the bottom of the silt accumulation tank. The movement of the first sleeve drives the first extrusion plate to move towards the bottom of the silt accumulation tank. The first extrusion plate squeezes the silt. The water generated by the extrusion enters the first extrusion plate through the first filtering hole and is discharged to the water collection assembly through the first water outlet pipe. The remaining silt remains in the silt accumulation tank, and the water generated by the extrusion is input into the water collection assembly. At the same time, the silt accumulation work and the silt extrusion work are carried out, reducing the time consumed for silt cleaning and improving the work efficiency.

[0028] By adopting the above technical solution, while the first squeezing plate squeezes the silt, the silt pumping assembly pumps part of the silt into the space between the first squeezing plate and the adjacent second squeezing plate. At the same time, the first rotating rod slides in the first thread groove to the end of the first thread groove, and the first rotating rod continues to rotate to drive the first sleeve to rotate. The rotation of the first sleeve drives the fixed end of the first telescopic rod to rotate, the rotation of the fixed end of the first telescopic rod drives the movable end of the first telescopic rod to rotate, the rotation of the movable end of the first telescopic rod drives the second rotating rod to rotate, and the second rotating rod rotates and slides in the second thread groove at the same time, thereby driving the second sleeve to move towards the bottom of the silt collecting tank. The movement of the second sleeve drives the second squeezing plate to move towards the bottom of the silt collecting tank. The second squeezing plate squeezes the silt, and the water generated by the squeezing enters the second squeezing plate through the second filtering hole and is discharged to the water collecting assembly through the second water outlet pipe, and the remaining silt remains in the silt collecting tank. When the silt enters the silt collecting assembly, the silt collecting assembly squeezes the silt and inputs the water generated by the squeezing into the water collecting assembly. At the same time, the silt collecting work and the squeezing of the silt are carried out, which reduces the time consumed for dredging and improves the work efficiency.

The rotation of the stirring shaft drives the stirring fan blades to rotate. While the stirring fan blades rotate, they drive the sediment entering the bucket to move towards the direction close to the sediment extraction pipe, improving the sediment extraction efficiency. At the same time, the sediment is screened by the stirring fan blades to avoid large stones in the sediment blocking the sediment extraction pipe.

[0045] By adopting the above technical solution, when the movable end of the second telescopic rod extends, the second telescopic rod pumps the water in the water collecting tank into the fixed end of the second telescopic rod through the first connecting pipe. When the movable end of the second telescopic rod shortens, the second telescopic rod pushes the water in the fixed end of the second telescopic rod towards the nozzle through the second connecting pipe, realizing the recycling of the water in the silt and improving the environmental protection of a silt cleaning device for a water conservancy project sluice.

Not less than one first filtering hole 4251 is evenly formed at one end of the first squeezing plate 425 near the bottom of the silt collecting box 41. One end of the first squeezing plate 425 is fixedly connected with a first water outlet pipe 426. The first water outlet pipe 426 is communicated with the cavity of the first squeezing plate 425. The first water outlet pipe 426 is connected to the water collecting assembly 5. A check valve is installed on the first water outlet pipe 426. The liquid in the first water outlet pipe 426 always flows in the direction away from the first squeezing plate 425.

[0087] Refer toFigure 3 , Figure 4 and Figure 5 , the second squeezing member 43 includes a second squeezing plate 431, a second sleeve 433, a second rotating rod 435, and a first telescopic rod 434. A cavity is formed inside the second squeezing plate 431. The second squeezing plate 431 is slidably installed in the silt collecting tank 41. The sliding direction of the second squeezing plate 431 is parallel to the axial direction of the rotating shaft 422. The peripheral side of the second squeezing plate 431 is in close contact with the inner wall of the silt collecting tank 41. At least one second filtering hole 4311 is uniformly formed at one end of the second squeezing plate 431 close to the bottom of the silt collecting tank 41. One end of the second squeezing plate 431 is fixedly connected to a second water outlet pipe 432. The second water outlet pipe 432 communicates with the cavity of the second squeezing plate 431. The second water outlet pipe 432 is connected to the water collecting assembly 5. A one-way valve is installed on the second water outlet pipe 432. The liquid in the second water outlet pipe 432 always flows in a direction away from the second squeezing plate 431. The second sleeve 433 passes through the second squeezing plate 431. The second sleeve 433 is rotatably connected to the second squeezing plate 431. The second sleeve 433 is coaxially arranged with the first sleeve 424. A second thread groove 4331 is formed inside the second sleeve 433. The surface of the second thread groove 4331 is smooth. The end of the second thread groove 4331 is closed.

[0088] When the silt collecting assembly 4 works, the silt pumping assembly 3 first pumps some silt into the space formed between the first squeezing plate 425 and the bottom of the silt collecting tank 41. Then the first motor 421 works. The output shaft of the first motor 421 rotates to drive the rotating shaft 422 to rotate. The rotating shaft 422 rotates to drive the first rotating rod 423 to rotate. While the first rotating rod 423 rotates, it slides in the first thread groove 4241, thereby driving the first sleeve 424 to move towards the bottom of the silt collecting tank 41. The movement of the first sleeve 424 drives the first squeezing plate 425 to move towards the bottom of the silt collecting tank 41. The first squeezing plate 425 squeezes the silt. The water generated by the squeezing enters the first squeezing plate 425 through the first filtering hole 4251 and is discharged to the water collecting assembly 5 through the first water outlet pipe 426. The remaining silt remains in the silt collecting tank 41.

[0089] While the first extrusion plate 425 extrudes the sludge, the sludge extraction assembly 3 pumps part of the sludge into the space between the first extrusion plate 425 and the adjacent second extrusion plate 431. At the same time, the first rotating rod 423 slides to the end of the first thread groove 4241 in the first thread groove 4241, and the first rotating rod 423 continues to rotate to drive the first sleeve 424 to rotate. The rotation of the first sleeve 424 drives the fixed end of the first telescopic rod 434 to rotate. The rotation of the fixed end of the first telescopic rod 434 drives the movable end of the first telescopic rod 434 to rotate. The rotation of the movable end of the first telescopic rod 434 drives the second rotating rod 435 to rotate. While the second rotating rod 435 rotates, it slides in the second thread groove 4331, thereby driving the second sleeve 433 to move towards the bottom of the sediment collection box 41. The movement of the second sleeve 433 drives the second extrusion plate 431 to move towards the bottom of the sediment collection box 41. The second extrusion plate 431 extrudes the sludge, and the water generated by the extrusion enters the second extrusion plate 431 through the second filter holes 4311 and is discharged to the water collection assembly 5 through the second water outlet pipe 432. The remaining sludge remains in the sediment collection box 41. While the sludge enters the sediment collection assembly 4, the sediment collection assembly 4 performs the extrusion work on the sludge, and inputs the water generated by the extrusion into the water collection assembly 5. At the same time, the sediment collection work and the work of extruding the sludge are carried out, reducing the time-consuming of dredging and improving the work efficiency.

[0090] Refer to Figure 2 and Figure 3 As shown in FIGS. 2 and 3, the sludge extraction assembly 3 includes a sludge inlet box 31, at least one sludge extraction pipe 33, a stirring shaft 34, a second motor 36, a driving bevel gear 37 and a driven bevel gear 38. The sludge inlet box 31 is fixedly installed on one side of the sediment collection box 41 close to the bucket 2. The sludge inlet box 31 is communicated with at least three sludge inlet pipes 32. The sludge inlet pipes 32 are arranged on the sludge inlet box 31 from top to bottom. The end of the sludge inlet pipe 32 away from the sludge inlet box 31 is communicated with the sediment collection box 41. At least one sludge inlet pipe 32 is arranged between the first extrusion plate 425 and the bottom of the sediment collection box 41. At least one sludge inlet pipe 32 is arranged between the first extrusion plate 425 and the adjacent second extrusion plate 431.

The driven bevel gear 38 is meshed with the driving bevel gear 37, and the driven bevel gear 38 is connected to the cutting assembly 6.

[0092] When the dredging assembly 3 works, the second motor 36 works and drives the stirring shaft 34 to rotate. The rotation of the stirring shaft 34 drives the stirring blades 35 to rotate. While the stirring blades 35 rotate, they drive the silt entering the bucket 2 to move towards the direction close to the dredging pipe 33, improving the dredging efficiency. At the same time, the silt is screened by the stirring blades 35 to prevent large stones in the silt from blocking the dredging pipe 33.

[0093] At the same time, the water pump works, and the silt in the bucket 2 is pumped into the silt inlet box 31 through the dredging pipe 33. The pressure in the silt inlet box 31 increases, and the silt in the silt inlet box 31 sequentially enters the silt collection box 41 from bottom to top through the silt inlet pipe 32, realizing the hierarchical entry of the silt into the silt collection box 41, facilitating the work of the silt collection assembly 4, and simultaneously performing the work of silt collection and squeezing the silt, reducing the time consumed for dredging and improving the work efficiency.

[0094] The rotation of the output shaft of the second motor 36 drives the driving bevel gear 37 to rotate. The rotation of the driving bevel gear 37 drives the driven bevel gear 38 to rotate. The rotation of the driven bevel gear 38 drives the cutting assembly 6 to work, improving the mechanical linkage of a dredging device for the gate of a water conservancy project.

[0095] Refer to Figure 1 and Figure 6, the cutting assembly 6 includes at least one nozzle 61, a connecting rod 62, a chute 621, a semi-gear 63, a rack 64, a spur gear 65, a fixed block 651, and a synchronous toothed belt 66.

The number of connecting rods 62 is the same as the number of nozzles 61. One end of the connecting rod 62 is fixedly connected to the nozzle 61, and the other end of the connecting rod 62 is rotatably installed on the bucket 2. A chute 621 is formed in the connecting rod 62, and the guiding direction of the chute 621 is parallel to the length direction of the connecting rod 62. The semi-gear 63 is fixedly installed at the end of the connecting rod 62 away from the nozzle 61. The rack 64 is slidably installed on the bucket 2. The rack 64 is connected to the water collection assembly 5, and the rack 64 is meshed with the semi-gear 63. The number of spur gears 65 is the same as the number of nozzles 61. The spur gears 65 are rotatably installed on the bucket 2. One of the spur gears 65 is coaxially and fixedly connected to the driven bevel gear 38. A fixed block 651 is fixedly connected to the spur gear 65. The fixed block 651 is eccentrically arranged with respect to the rotation axis of the spur gear 65. The fixed block 651 is slidably installed in the chute 621. The synchronous toothed belt 66 is wound around the spur gears 65, and the synchronous toothed belt 66 is meshed with the spur gears 65.

[0096] Referring to Figure 2 , Figure 3 and Figure 6 , the water collection assembly 5 includes a water collection tank 51, a first connecting pipe 52, a filter screen 521, a second telescopic rod 53, and a second connecting pipe 54. The water collection tank 51 is fixedly installed on the side of the silt collection tank 41 away from the silt inlet tank 31. The first outlet pipe 426 and the second outlet pipe 432 are both communicated with the water collection tank 51. The first connecting pipe 52 penetrates through the water collection tank 51. The first connecting pipe 52 is communicated with the water collection tank 51. A one-way valve is installed on the first connecting pipe 52, and the liquid in the first connecting pipe 52 always flows away from the water collection tank 51. The fixed end of the second telescopic rod 53 is fixedly installed on the bucket 2. The rack 64 is fixedly connected to the movable end of the second telescopic rod 53. The sliding direction of the rack 64 is parallel to the telescopic direction of the second telescopic rod 53. One end of the first connecting pipe 52 away from the water collection tank 51 is communicated with the rodless cavity of the fixed end of the second telescopic rod 53. A filter screen 521 is fixedly installed at the end of the first connecting pipe 52 away from the second telescopic rod 53. One end of the second connecting pipe 54 is communicated with the rodless cavity of the fixed end of the second telescopic rod 53, and the other end of the second connecting pipe 54 is communicated with the nozzle 61.

A one-way valve is installed on the second connecting pipe 54, and the liquid in the second connecting pipe 54 always flows towards the nozzle 61.

[0097] When the dredging component 3 is working, the driven bevel gear 38 rotates. The rotation of the driven bevel gear 38 drives the spur gear 65 fixedly connected to the driven bevel gear 38 to rotate. The rotation of the spur gear 65 drives the synchronous toothed belt 66 to move. The movement of the synchronous toothed belt 66 drives the remaining spur gears 65 to rotate synchronously. The rotation of the spur gear 65 drives the fixed block 651 to rotate. While rotating, the fixed block 651 slides in the chute 621. The rotation of the fixed block 651 drives the connecting rod 62 to swing reciprocally on the bucket 2. The reciprocal swing of the connecting rod 62 drives the nozzle 61 to swing reciprocally. The nozzle 61 sprays high-pressure water jets on the silt, playing a role in breaking the silt, and thus improving the dredging efficiency of the dredging component 3.

[0098] While the connecting rod 62 swings reciprocally, it drives the half gear 63 to swing reciprocally. The reciprocal swing of the half gear 63 drives the rack 64 to move reciprocally on the bucket 2. The reciprocal movement of the rack 64 drives the movable end of the second telescopic rod 53 to extend and retract. When the movable end of the second telescopic rod 53 extends, the second telescopic rod 53 pumps the water in the water collection tank 51 into the fixed end of the second telescopic rod 53 through the first connecting pipe 52. When the movable end of the second telescopic rod 53 shortens, the second telescopic rod 53 pushes the water in the fixed end of the second telescopic rod 53 towards the nozzle 61 through the second connecting pipe 54, realizing the recycling of the water in the silt and improving the environmental protection of a sluice dredging device for water conservancy projects.

[0099] The implementation principle of an embodiment of a sluice dredging device for water conservancy projects in this application is as follows: By driving the driving wheel 11 to rotate, the device housing 1 is driven to move. The cutting component 6 cuts the silt. While the device housing 1 is moving, the bucket 2 aggregates the silt in the bucket 2. The dredging component 3 pumps the silt into the silt collection component 4. When the silt enters the silt collection component 4, the silt collection component 4 performs extrusion work on the silt and inputs the water generated by the extrusion into the water collection component 5. While performing the silt collection work and the silt extrusion work, the time consumed for dredging is reduced and the work efficiency is improved.

[0100] The above are all the preferred embodiments of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
