Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, in particular to a device for desilting a water channel during water conservancy project construction. Background Art

[0002] In the field of water conservancy, canal siltation is a common problem, especially in complex working conditions where high-viscosity silt (water content <60%, viscosity >2000cP) is mixed with rocks and other debris. This seriously affects water delivery efficiency and increases equipment wear and tear. Data shows that over 65% of my country's irrigation canals are silted, of which 38% is high-viscosity silt and 25% contains hard debris. Traditional silt removal equipment reduces efficiency by 40% in such scenarios, and equipment failure rate increases by three times.

[0003] Existing dredging equipment faces two technical bottlenecks: First, when handling highly viscous silt, the silt easily adheres to the inner wall of the pipe, forming a 5-10 mm mud cake, which reduces the flow cross-sectional area by 30%-50%. A Yellow River irrigation project once experienced a pipe blockage due to mud cake accumulation, with a single dredging cost of 80,000 yuan. Second, the interception efficiency of debris such as rocks is less than 70%. Hard objects entering the pump body cause impeller wear (0.2 mm / h). In one municipal project, the pump body required maintenance as frequently as twice a week due to rock impacts.

[0004] In addition, traditional water addition and dilution systems mostly use fixed-flow water replenishment, which cannot adapt to fluctuations in sludge viscosity. Problems such as "insufficient water replenishment leading to blockage" or "excessive water replenishment leading to increased energy consumption" often occur. For example, in a certain Yangtze River tributary project, fixed-flow water replenishment increased the energy consumption of sludge transportation by 28% compared with the optimized working conditions. Therefore, the development of dredging equipment with both adaptive water replenishment and dilution and debris cleaning functions has become an urgent need to break through technical bottlenecks.

[0005] Chinese patent (publication number CN215483219U), which discloses a dredging device for a water channel for water conservancy project construction, including a panel, wherein walking wheels are provided at the four corners of the lower end of the panel, and the left and right parts of the panel are respectively provided with a No. 2 through hole and a No. 1 through hole. A platform is fixedly installed on the front side of the upper end of the panel, and 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, and a dredging mechanism and a collecting mechanism are respectively provided on the outer surface of the driving mechanism. The dredging mechanism is located on the left side of the collecting mechanism, and the lower end of the dredging mechanism passes through the interior of the No. 2 through hole, and the lower end of the collecting mechanism passes through the interior of the No. 1 through hole. The dredging device for a water channel for water conservancy project construction described in this utility model can adjust the inclination angle of the dredging device according to the inclination angle of the bottom of the water channel, avoid dredging dead corners during the dredging process, thoroughly remove the silt at the bottom of the water channel, ensure the dredging effect, realize synchronous silt collection operation, and improve the dredging efficiency.

[0006] According to the above scheme, during dredging, the driving operation of the driving mechanism synchronously drives the dredging mechanism and the collecting mechanism to adjust the inclination angle of the dredging device according to the inclination angle of the bottom of the canal, so as to avoid dredging dead corners during the dredging process. However, during the dredging process, the silt has high viscosity and sticks to the inner wall of the pipe, which cannot be solved, and hard objects such as stones cannot be cleaned, which has limitations. For this reason, we propose a dredging device for water channels used in water conservancy project construction. Summary of the Invention

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. When the present invention is used, when the silt passes through the matching opening inside the mobile tube, if the silt is too viscous and causes the resistance to increase, the mobile tube will drive the mobile round box to move and retract the telescopic arm, and at the same time pull the matching long tube to make the water permeable opening on the outer wall of the annular water box separate from the annular tube. At this time, the negative pressure generated by the suction of the suction pump in the matching tube is transmitted to the annular water box through the mobile round box and the matching long tube, so that it draws water from the outer sleeve and discharges it through the water nozzle, diluting the silt in the matching tube, effectively preventing the silt from being too viscous and adhering to the inner wall of the pipe and affecting the circulation speed, ensuring that the silt is smoothly absorbed by the suction pump and discharged through the discharge pipe.

[0022] 2. When the present invention is in use, when silt is discharged from the matching port of the moving pipe, the matching port can filter large stones, effectively preventing stones from entering the suction pump and causing damage, thereby ensuring the safety of the equipment. When the matching port is blocked, the moving pipe drives the moving round box to continue moving, so that the abutment block disengages from the abutment and resets under the action of the spring, and the bottom connecting port of the moving pipe is connected with the storage box. At the same time, the telescopic arm pulls the connecting rod to drive the recovery line wheel to make the first and second circular plates seal the moving port. At this time, the suction pump sucks the storage box, and the storage box sucks the matching pipe through the connecting pipe, so that the obstruction in the moving pipe enters the storage box and falls due to gravity, realizing the function of automatic unblocking of blockage, and the blockage can be cleared without manual intervention, thereby ensuring the continuity and efficiency of the dredging operation, while avoiding equipment failure and maintenance shutdown caused by blockage, thereby improving the reliability and practicality of the dredging device.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Example 1: Please refer to Figures 1 to 4As shown, in the embodiment of the present invention, a canal desilting device for water conservancy project construction includes a mobile casing 1.

An electric cylinder 14 is rotatably connected between the matching casing 5 and the mobile casing 1. The electric cylinder 14 can control the height of the matching casing 5 by adjusting the length. The inner wall of the matching casing 5 is rotatably connected to a connecting shaft 3 through a rotating shaft. The outer wall of the connecting shaft 3 is fixedly connected to a spiral sheet 4. The outer wall of the matching casing 5 is also fixed A servo motor 7 is fixedly installed to drive the connecting shaft 3 and the spiral sheet 4 to rotate. Specifically, the output end of the servo motor 7 is fixedly connected to the first transmission wheel 8 by a bolt, and the end of the connecting shaft 3 close to the first transmission wheel 8 is fixedly connected to the second transmission wheel 10. A transmission belt 9 is provided in a tensioning sleeve between the first transmission wheel 8 and the second transmission wheel 10. More specifically, a tensioner is fixedly installed on the outer wall of the matching shell 5, and the outer wall of the abutment 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 abutment wheel of the tensioner to control the tensioning degree of the transmission belt 9. The tensioner is a prior art and is not shown in the figure, so it will not be described in detail here.

[0039] The inner wall of the mobile casing 1 is fixedly connected to the matching pipe 20 by bolts, and the matching shell 5 and the mobile casing 1 are fixedly connected with a connecting material pipe 13. The matching pipe 20 and the connecting material pipe 13 are fixedly connected through a pipeline, which is 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, and also has good elasticity. The inner wall of the matching shell 5 is fixedly connected to the main pipe 12, and the outer wall of the main pipe 12 is fixedly connected to multiple suction pipes 11. The inner wall of the mobile casing 1 is fixedly installed with a suction pump 18, and the feed port of the suction pump 18 is fixedly connected to the matching pipe 20.

When the suction pump 18 draws sludge through the matching pipe 20, stones in the sludge will be intercepted and filtered out by the filtering mechanism 201 to avoid damage to the suction pump 18. When the sludge viscosity 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 pipe, affecting use. A battery 16 is also fixedly installed on the bottom end of the inner wall of the mobile housing 1, and a power cord 17 is fixedly connected to the outer wall of the mobile housing 1. The power cord 17 needs to be reserved for a length of ten to twenty meters. The power cord 17 can provide power to the electric machinery inside the mobile housing 1. If the power cord 17 breaks and short-circuits and cannot supply power, the battery 16 can supply power for emergency.

[0040] Example 2: Please refer to Figures 4 to 11 As shown, the water adding mechanism 101 includes an outer sleeve 23, which is sleeved and fixed on the outer wall of the matching tube 20. The upper end of the outer sleeve 23 is fixedly connected to the water suction pipe 19. The inner wall of the outer sleeve 23 is welded and fixed with an abutting annular tube 28. The inner wall of the outer sleeve 23 is slidably connected to the annular water box 30 with a reset function. The annular water box 30 is fixedly connected to the inner wall of the outer sleeve 23 by multiple first springs 29. The multiple first springs 29 are distributed in a circle between the outer sleeve 23 and the annular water box 30, abutting the outer wall of the annular tube 28. The wall abuts against the outer wall of the annular water box 30. The outer wall of the annular water box 30 is provided with a plurality of water permeable openings 33. The plurality of water permeable openings 33 are distributed circumferentially on the outer wall of the annular water box 30. A movable circular box 22 is provided inside the matching tube 20. The movable circular box 22 and the annular water box 30 are fixedly connected through a plurality of matching long tubes 31. The inner wall of each matching long tube 31 is fixedly connected with a plurality of support rings. The support ring can support the inner wall of the matching long tube 31 to prevent the matching long tube 31 from becoming flat when squeezed, thereby affecting the internal circulation.

[0041] Multiple matching long tubes 31 are distributed in a circular pattern between the mobile round box 22 and the annular water box 30. The outer wall of each matching long tube 31 is slidably inserted into the interior of the matching tube 20. The outer wall of the mobile round box 22 is provided with multiple water spraying ports 36. The end of the mobile round box 22 away from the water spraying ports 36 is fixedly connected to the mobile tube 24 through a connecting arm.

[0042] The upper end of the water suction pipe 19 is fixedly connected to a folding pipe 51, and the upper end of the folding pipe 51 is fixedly connected to a buoyancy box 52. The upper end of the buoyancy box 52 is fixedly connected to a water supply pipe 6. The bottom of the buoyancy box 52 is fixedly connected to multiple straws 50. The multiple straws 50 are distributed in a circle at the bottom of the buoyancy box 52, and the buoyancy box 52 is made of foam material. A valve is fixedly installed inside each straw 50 and the water supply pipe 6. The valve is not shown in the figure, and the valves are all existing technologies. No more details are given here. When the mobile housing 1 is immersed in water, the buoyancy box 52 has buoyancy in the water. When the buoyancy box 52 floats in the water, the folding pipe 51 is connected to the water supply pipe 6. The stacked tube 51 will be stretched, and the valve inside the water standby pipe 6 is in a closed state. When negative pressure suction is generated inside the folded tube 51, the folded tube 51 will suck water through the buoyancy box 52 and the suction pipe 50. Since the water at the bottom of the water channel is relatively turbid, suction can be performed on the water surface, and the suction pipe 50 can also prevent larger debris from entering the buoyancy box 52. If there is no water in the canal, the valve inside the water standby pipe 6 can be opened, and the water pipe can be connected to the water standby pipe 6. Water will enter the buoyancy box 52. Since water can be sucked and replenished at this time, water can be replenished for use when there is no water in the canal.

[0043] 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. A second spring 34 is fixedly connected between the outer wall of the connecting rod 35 and the first circular plate 37. The second spring 34 is sleeved on the outer wall of the connecting rod 35. The elastic coefficient of the second spring 34 is greater than the elastic coefficient of the first spring 29. The end of the first circular plate 37 away from the connecting rod 35 is rotatably connected through a rotating shaft. A second circular plate 38 having a reset function is provided. A reset torsion spring is fixedly connected between the second circular plate 38 and the first circular plate 37. A plurality of movable openings 39 are provided on the outer walls of the first circular plate 37 and the second circular plate 38. The plurality of movable openings 39 are distributed circumferentially on the first circular plate 37 and the second circular plate 38. A recovery pulley 41 is fixedly connected to one end of the second circular plate 38 away from the first circular plate 37. The outer wall of the connecting rod 35 is slidably penetrated through the first circular plate 37, the second circular plate 38 and the recovery pulley 41. A first pull rope 40 is wound around the outer wall of the recovery pulley 41. The free end of the first pull rope 40 is fixedly connected to the outer wall of the connecting rod 35.

[0044] 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. A plurality of third springs 48 are fixedly connected between the abutment block 47 and the inner wall of the sliding box 45. The elastic coefficient of the third spring 48 is greater than that of the second spring 34. The outer wall of the abutment block 47 abuts against the outer wall of the movable tube 24. An electric telescopic arm 49 is fixedly installed on the outer wall of each sliding box 45. An intelligent time relay is fixedly installed inside each electric telescopic arm 49.

[0045] The bottom of the matching tube 20 is provided with a first connection port 42. Figure 7 The bottom end of the inner wall of the mobile casing 1 is fixedly connected with a storage box 15 by bolts. The storage box 15 is fixedly connected to the second connecting port 43 through a pipe, and the storage box 15 is fixedly connected to the matching pipe 20 through a connecting pipe 25.

[0046] The working principle of the present invention is:

[0047] When the present invention is used, the crawler wheel is started to drive the transmission crawler 2 for transmission, and the transmission crawler 2 will drive the mobile housing 1 into the canal. Note that the water suction pipe 19 is in the water at this time. At this time, the servo motor 7 is started to drive the first transmission wheel 8 to rotate, and 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, and the connecting shaft 3 drives the spiral piece 4 to rotate. The spiral piece 4 will break up the silt, and then start the suction pump 18. The suction pump 18 will suck the matching pipe 20, and 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 multiple suction pipes 11;

[0048] When the silt passes through the inside of the moving tube 24 and passes through the inside of the matching port 27, if the silt is very viscous, the resistance becomes larger when passing through the inside of the matching port 27, and the moving tube 24 will drive the moving round box 22 to move, and the moving round box 22 will contract the telescopic arm 32, and the moving round box 22 will pull all the matching long tubes 31, and the matching long tubes 31 will pull the annular water box 30. When all the water permeable openings 33 on the outer wall of the annular water box 30 are separated from the abutment with the outer wall of the annular tube 28, at this time, since the moving round box 22 is located inside the matching tube 20, the inside of the matching tube 20 is sucked by the suction pump 18, and the matching tube 20 is sucked by the suction pump 18. Negative pressure is generated inside, and the mobile round box 22 is connected to the inner wall of the matching pipe 20 through the water spray port 36. At this time, negative pressure is also generated inside the mobile round box 22, and the inside of the annular water box 30 is sucked by the matching long tube 31. The annular water box 30 will suck the inside of the outer sleeve 23, and the outer sleeve 23 will suck water through the inside of the storage box 15. The water will be discharged from the water spray port 36 and enter the sludge inside the matching pipe 20 to dilute it, preventing the sludge from being too viscous and sticking to the inner wall of the pipe, affecting the sludge circulation speed. When the sludge is absorbed into the discharge pipe 21 by the suction pump 18, the discharge pipe 21 needs to be connected to the pipe so that the discharge pipe 21 can discharge the sludge.

[0049] When the silt passes through the interior of the moving tube 24 and is discharged from the matching port 27, the matching port 27 can also filter large stones to prevent the stones from entering the interior of the suction pump 18 and causing damage to the suction pump 18. When the matching port 27 is mostly blocked, this matching port 27 will drive the moving round box 22 to continue moving. When the leftmost end of the moving tube 24 gradually moves to the angle of the smallest angle of the abutment block 47, when the angle of the smallest angle of the abutment block 47 is separated from the abutment with the outer wall of the moving tube 24, the third spring 48 will drive the abutment block 47 to move, and the outer wall of the moving tube 24 will move rapidly along the inclined wall of the abutment block 47. At this time, the second connecting port 43 at the bottom of the moving tube 24 is connected to the first connecting port 42 and is connected to the storage box 15. The movable tube 24 will move the connecting rod 35 through the telescopic arm 32, and the connecting rod 35 will pull the first pull rope 40, and the first pull rope 40 will rotate the recovery wheel 41, and the recovery wheel 41 will drive the second circular plate 38 to rotate. At this time, the moving opening 39 on the outer wall of the first circular plate 37 and the second circular plate 38 will be disconnected from each other, and the first circular plate 37 and the second circular plate 38 will block the moving opening 39. At this time, the suction pump 18 will suck the storage box 15, and the storage box 15 will suck the inside of the matching tube 20 through the connecting pipe 25. At this time, the first connecting port 42 is connected to the second connecting port 43, and the obstruction inside the movable tube 24 will enter the interior of the storage box 15 and fall to the bottom end of the inner wall of the storage box 15 due to gravity;

[0050] At this time, please note that four to six seconds after the abutment block 47 moves, the intelligent time relay activates the electric telescopic arm 49 to drive the moving plate 26 to move, and the moving plate 26 pulls the second pull rope 46, and the second pull rope 46 drives the abutment block 47 to reset.
