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 channels in water conservancy project construction. Background Art

[0002] In the field of water conservancy projects, the problem of silt accumulation in water channels is widespread. Especially in complex working conditions where high-viscosity silt (water content < 60%, viscosity > 2000 cP) is mixed with sundries such as stones, it seriously affects the water conveyance efficiency and increases equipment wear. Data shows that more than 65% of irrigation water channels in China have silt accumulation, among which 38% is high-viscosity silt and 25% contains hard sundries. The efficiency of traditional silt cleaning devices decreases by 40% in such scenarios, and the equipment failure rate increases by 3 times. Existing silt cleaning devices face two technical bottlenecks: First, when dealing with high-viscosity silt, the silt is easily adhered to the inner wall of the pipeline to form a mud cake with a thickness of 5 - 10 mm, resulting in a reduction of the flow cross-sectional area by 30% - 50%. In a certain Yellow River irrigation area project, the pipeline was blocked due to the accumulation of mud cakes, and the single dredging cost reached 80,000 yuan. Second, the interception efficiency of sundries such as stones is less than 70%. After hard objects enter the pump body, the impeller is worn (0.2 mm / h). In a certain municipal engineering project, the pump body needs to be repaired up to 2 times a week due to stone impacts. In addition, most traditional water dilution systems are fixed-flow water replenishment, which cannot adapt to the fluctuations in silt viscosity, and often have problems such as "insufficient water replenishment causing blockage" or "excessive water replenishment causing increased energy consumption". For example, in a certain project on a tributary of the Yangtze River, the fixed-flow water replenishment increased the energy consumption of silt transportation by 28% compared with the optimized working condition. Therefore, developing a silt cleaning device with both adaptive water dilution and sundries cleaning functions has become an urgent need to break through technical bottlenecks.

[0003] Chinese Patent (Publication No. CN215483219U) discloses a silt cleaning device for water channels in water conservancy project construction, including a panel. Four corners at the lower end of the panel are respectively provided with traveling wheels. A second through hole and a first through hole are respectively formed in the left part and the right part of the panel. A platform is fixedly installed on the front side of the upper end of the panel. A driving mechanism is fixedly installed on the upper end of the platform. The lower end of the driving mechanism is fixedly connected to the upper end of the panel. The outer surface of the driving mechanism is respectively provided with a silt cleaning mechanism and a collection mechanism. The silt cleaning mechanism is located on the left side of the collection mechanism. The lower end of the silt cleaning mechanism penetrates into the second through hole, and the lower end of the collection mechanism penetrates into the first through hole. The disclosed silt cleaning device for water channels in water conservancy project construction can adjust the inclination angle of the silt cleaning device according to the inclination angle of the water channel bottom, avoid silt cleaning dead corners during the silt cleaning process, completely remove the silt at the bottom of the water channel, ensure the silt cleaning effect, and realize synchronous silt collection operation, thereby improving the silt cleaning efficiency.

[0004] According to the above solution, during dredging, the driving operation of the driving mechanism synchronously drives the dredging mechanism and the collection mechanism to adjust the inclination angle of the dredging device according to the inclination angle of the bottom of the water channel, avoiding dredging dead corners during the dredging process. However, during the dredging process, the problem that the sludge viscosity is too high and adheres to the inner wall of the pipeline cannot be solved, and hard objects such as stones cannot be cleaned, which has limitations.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. When the present invention is in use, when the silt passes through the mating port inside the moving pipe, if the silt is viscous and causes the resistance to increase, the moving pipe will drive the moving round box to move and contract the telescopic arm, while pulling the mating long pipe to disengage the water-permeable port on the outer wall of the ring water box from the abutting ring pipe. At this time, the negative pressure generated by the suction pump in the mating pipe is transmitted to the ring water box through the moving round box and the mating long pipe, causing it to suck water from the outer sleeve pipe and discharge it through the water spray port, diluting the silt in the mating pipe. This effectively prevents the silt from adhering too tightly to the inner wall of the pipe and affecting the flow rate, ensuring that the silt is smoothly sucked by the suction pump and discharged through the discharge pipe. The entire process requires no manual intervention and can automatically trigger water replenishment and dilution according to the silt viscosity, improving the dredging efficiency and avoiding pipe blockage.

[0017] 2. When the present invention is in use, when the silt is discharged from the mating port of the moving pipe, the mating port can filter large stones, effectively preventing the stones from entering the suction pump and causing damage, ensuring the safety of the equipment. When the mating port is blocked, the moving pipe drives the moving round box to continue moving, causing the abutting block to disengage and reset under the action of the spring. The connection port at the bottom of the moving pipe is connected to the storage box. At the same time, the telescopic arm pulls the connecting rod to drive the recovery wire wheel to block the moving port with the first and second round plates. At this time, the suction pump sucks the storage box, and the storage box sucks the mating pipe through the connecting pipe, causing the blockage in the moving pipe to enter the storage box and fall due to gravity, realizing the function of automatically dredging the blockage. The blockage can be cleared without manual intervention, ensuring the continuity and high efficiency of the dredging operation. At the same time, it avoids equipment failures and shutdown maintenance caused by blockages, improving the reliability and practicality of the dredging device. BRIEF DESCRIPTION OF THE DRAWINGS

The outer wall of the mobile housing 1 is rotatably connected with a plurality of track wheels through a rotating shaft. The inner wall of each drive track 2 is tensioned and abutted against the outer wall of the adjacent track wheel. The outer wall of the mobile housing 1 is rotatably connected with a matching housing 5 through a rotating shaft. An electric cylinder 14 is rotatably connected between the matching housing 5 and the mobile housing 1. The electric cylinder 14 can control the height of the matching housing 5 by adjusting its length. The inner wall of the matching housing 5 is rotatably connected with a connecting shaft 3 through a rotating shaft. A spiral blade 4 is fixedly connected to the outer wall of the connecting shaft 3. A servo motor 7 capable of driving the connecting shaft 3 and the spiral blade 4 to rotate is also fixedly installed on the outer wall of the matching housing 5. Specifically, the output end of the servo motor 7 is fixedly connected with a first transmission wheel 8 through bolts. One end of the connecting shaft 3 close to the first transmission wheel 8 is fixedly connected with a second transmission wheel 10.

More specifically, a tensioner is fixedly installed on the outer wall of the matching housing 5. The outer wall of the abutting wheel of the tensioner abuts against the outer wall of the transmission belt 9. When the transmission belt 9 becomes loose after long-term use, the tension of the transmission belt 9 is adjusted by adjusting the abutting wheel of the tensioner to control the tension degree of the transmission belt 9. The tensioner is a prior art and is not shown in the figure, so no more details will be described here; A matching pipe 20 is fixedly connected to the inner wall of the mobile housing 1 through bolts. A connecting material pipe 13 is fixedly connected between the matching housing 5 and the mobile housing 1. The matching pipe 20 and the connecting material pipe 13 are fixedly connected and communicated through a pipeline (not shown in the figure). The connecting material pipe 13 is made of rubber material. The rubber material has good corrosion resistance and high temperature resistance characteristics, and also has good elasticity.

A water adding mechanism 101 is fixedly installed on the inner wall of the matching pipe 20. A filtering mechanism 201 is also fixedly installed on the outer wall of the matching pipe 20. When the suction pump 18 pumps sludge through the matching pipe 20, the stones in the sludge will be intercepted and filtered by the filtering mechanism 201 to avoid damaging the suction pump 18. And when the viscosity of the sludge is too high, the water adding mechanism 101 will automatically add water to avoid the sludge being too viscous and sticking to the inner wall of the pipeline, affecting the use. A storage battery 16 is also fixedly installed at the bottom end of the inner wall of the mobile housing 1. A power cord 17 is fixedly connected to the outer wall of the mobile housing 1. The power cord 17 needs to be reserved with a length of ten to twenty meters. The power cord 17 can provide power for the electric machinery inside the mobile housing 1. When the power cord 17 breaks and is short-circuited and cannot supply power, the storage battery 16 can supply power for emergency.

[0032] Embodiment Two: Please refer toFigures 4 to 11 As shown in the figure, the water filling mechanism 101 includes an outer sleeve 23, which is sleeved and fixed on the outer wall of the mating pipe 20. The upper end of the outer sleeve 23 is fixedly communicated with a water suction pipe 19. A butt joint ring pipe 28 is fixedly welded on the inner wall of the outer sleeve 23. A ring-shaped water box 30 with a reset function is slidably connected to the inner wall of the outer sleeve 23. The ring-shaped water box 30 and the inner wall of the outer sleeve 23 are fixedly connected by a plurality of first springs 29. The plurality of first springs 29 are circumferentially distributed between the outer sleeve 23 and the ring-shaped water box 30. The outer wall of the butt joint ring pipe 28 abuts against the outer wall of the ring-shaped water box 30. A plurality of water permeable openings 33 are formed on the outer wall of the ring-shaped water box 30. The plurality of water permeable openings 33 are circumferentially distributed on the outer wall of the ring-shaped water box 30. A moving round box 22 is arranged inside the mating pipe 20. The moving round box 22 and the ring-shaped water box 30 are fixedly communicated by a plurality of mating long pipes 31. A plurality of support rings are fixedly connected to the inner wall of each mating long pipe 31. The support rings can support the inner wall of the mating long pipe 31 to prevent the mating long pipe 31 from being flattened when being squeezed, affecting the internal flow; The plurality of mating long pipes 31 are circumferentially distributed between the moving round box 22 and the ring-shaped water box 30. The outer wall of each mating long pipe 31 slidably penetrates through the inside of the mating pipe 20. A plurality of water spraying openings 36 are formed on the outer wall of the moving round box 22. One end of the moving round box 22 far away from the water spraying openings 36 is fixedly connected with a moving pipe 24 through a connecting arm. Please refer to Figure 7 , a plurality of mating openings 27 are formed on the outer wall of the moving pipe 24. A second connecting port 43 is further formed at the bottom of the moving pipe 24. The outer wall of the moving pipe 24 fits against the inner wall of the mating pipe 20; The upper end of the water suction pipe 19 is fixedly communicated with a folding pipe 51. The upper end of the folding pipe 51 is fixedly communicated with a buoyancy box 52. The upper end of the buoyancy box 52 is fixedly connected with a water supply pipe 6. A plurality of suction pipes 50 are fixedly communicated with the bottom of the buoyancy box 52.

A valve is fixedly installed inside each suction pipe 50 and the water supply pipe 6. The valves are not shown in the figure and the valves are all prior arts and will not be elaborated here. When the moving machine shell 1 is immersed in water, due to the buoyancy of the buoyancy box 52 in water, when the buoyancy box 52 floats in water, the folding pipe 51 will be stretched. And at this time, the valve inside the water supply pipe 6 is in a closed state. When negative pressure suction is generated inside the folding pipe 51, the folding pipe 51 will suck water through the buoyancy box 52 and the suction pipes 50. Since the water at the bottom is relatively turbid, the water on the water surface can be sucked, and the suction pipes 50 can also prevent larger sundries from entering the buoyancy box 52. If there is no water in the water channel, the valve inside the water supply pipe 6 can be opened, and a water pipe can be docked inside the water supply pipe 6, and water will enter the buoyancy box x 52. Since water can be sucked and supplemented at this time, water can be supplemented and used when there is no water in the water channel; The filtering mechanism 201 includes a telescopic arm 32, which is fixedly connected to the outer wall of the mobile round box 22. The end of the telescopic arm 32 away from the mobile round box 22 is fixedly connected to a connecting rod 35. A first circular plate 37 is welded and fixedly connected to the inside of the matching tube 20. The outer wall of the first circular plate 37 is welded and fixed to the inner wall of the matching tube 20.

The outer wall of the matching tube 20 is also fixedly connected to a plurality of sliding boxes 45 by bolts. The inner wall of each sliding box 45 is slidably connected to an abutment block 47 with a reset function.

[0033] The working principle of the present invention is: When the present invention is in use, start the crawler wheel to drive the transmission crawler belt 2 for transmission. The transmission crawler belt 2 will drive the moving housing 1 into the water channel. Note that at this time, the suction pipe 19 is in the water. Then start the servo motor 7 to drive the first transmission wheel 8 to rotate. The first transmission wheel 8 drives the second transmission wheel 10 to rotate through the transmission belt 9. The second transmission wheel 10 drives the connecting shaft 3 to rotate. The connecting shaft 3 will drive the spiral blade 4 to rotate. The spiral blade 4 will break and disperse the silt. Then start the suction pump 18. The suction pump 18 will suck the matching pipe 20. The matching pipe 20 will suck the inside of the main pipe 12 through the connecting material pipe 13. The main pipe 12 will suck the silt through a plurality of suction pipes 11; When the silt passes through the inside of the moving pipe 24 and passes through the inside of the matching port 27, if the silt is very viscous when passing through the inside of the matching port 27, the resistance becomes larger. The moving pipe 24 will drive the moving round box 22 to move. The moving round box 22 will contract the telescopic arm 32. The moving round box 22 will pull all the matching long pipes 31. The matching long pipes 31 will pull the ring water box 30. When all the water permeable ports 33 on the outer wall of the ring water box 30 are disengaged from the abutment with the outer wall of the abutment ring pipe 28, at this time, since the moving round box 22 is located inside the matching pipe 20, the inside of the matching pipe 20 is sucked by the suction pump 18, and a negative pressure is generated inside the matching pipe 20. And the moving round box 22 is communicated with the inner wall of the matching pipe 20 through the water spraying port 36. At this time, a negative pressure will also be generated inside the moving round box 22 to suck the inside of the ring water box 30 through the matching long pipe 31. The ring water box 30 will suck the inside of the outer sleeve pipe 23. The outer sleeve pipe 23 will suck water from the inside of the storage tank 15. The water will be discharged from the water spraying port 36 and enter the silt inside the matching pipe 20 for dilution, preventing the silt from being too viscous and sticking to the inner wall of the pipeline, which affects the flow rate of the silt. When the silt is absorbed by the suction pump 18 to the discharge pipe 21, a docking pipe needs to be connected to the discharge pipe 21, and the discharge pipe 21 discharges the silt; When the sludge passes through the inside of the moving pipe 24 and is discharged from the mating port 27, the mating port 27 can also filter large stones to prevent the stones from entering the inside of the suction pump 18 and causing damage to the suction pump 18. When most of the mating port 27 is blocked, the mating port 27 will drive the moving round box 22 to continue moving. When the leftmost end of the moving pipe 24 gradually moves to the angle of the abutting block 47 with the smallest angle, when the angle of the abutting block 47 with the smallest angle disengages from the abutment with the outer wall of the moving pipe 24, at this time, the third spring 48 will drive the abutting block 47 to move, and the outer wall of the moving pipe 24 will move rapidly along the inclined wall of the abutting block 47. At this time, the second connection port 43 at the bottom of the moving pipe 24 is communicated with the first connection port 42 and is communicated with the storage tank 15. The moving pipe 24 will move the connecting rod 35 through the telescopic arm 32. The connecting rod 35 pulls the first pulling rope 40. The first pulling rope 40 rotates the recovery wire wheel 41. The recovery wire wheel 41 drives the second circular plate 38 to rotate. At this time, the moving ports 39 on the outer walls of the first circular plate 37 and the second circular plate 38 will be disengaged from each other. The first circular plate 37 and the second circular plate 38 will block the moving port 39. At this time, the suction pump 18 will suck the storage tank 15. The storage tank 15 will suck the inside of the mating pipe 20 through the communication pipe 25. At this time, the first connection port 42 is communicated with the second connection port 43, and the blockage inside the moving pipe 24 will enter the inside of the storage tank 15 and fall to the bottom end of the inner wall of the storage tank 15 due to gravity; Note that at four to six seconds after the abutting block 47 moves, the intelligent time relay starts, and the electric telescopic arm 49 will drive the moving plate 26 to move. The moving plate 26 will pull the second pulling rope 46. The second pulling rope 46 will drive the abutting block 47 to reset. When there is no blockage inside the moving pipe 24 at this time, the second spring 34 drives the connecting rod 35 to reset. The connecting rod 35 drives the moving pipe 24 to reset through the telescopic arm 32. The moving pipe 24 will drive the second connection port 43 to disengage from the first connection port 42.
