Abstract
Description
Technical Field
[0001] This invention relates to the field of river dredging technology, and in particular to a silt removal device suitable for river management. Background Technology
[0002] As an important carrier of water resources and a component of the ecological environment, the problem of siltation in rivers is becoming increasingly prominent. Especially for narrower rivers, silt not only reduces the flood discharge capacity of the river and causes floods, but also becomes an endogenous source of pollution, continuously releasing pollutants and disrupting the ecological balance of the water body. Therefore, regular dredging and treatment of narrower rivers is a key measure to maintain the function of the river and improve the water environment.
[0003] Currently, common river dredging methods mainly include mechanical dredging and pump dredging. Mechanical dredging typically uses dredgers or excavators to directly excavate and transport the silt. While this method is highly efficient, it has several significant drawbacks: First, the equipment is bulky and causes considerable disturbance to the riverbanks and surrounding environment; second, during the dredging process, components such as the bucket can easily agitate the silt, causing pollutants to spread and resulting in secondary pollution; third, the dredged silt has an extremely high water content, leading to enormous transportation and treatment costs.
[0004] Pump-suction dredging technology, such as using cutter suction dredging vessels, directly sucks up silt through the pump body, reducing disturbance to the river channel to some extent. However, existing pump-suction dredging devices still have limitations: First, the dredging head does not fit well with the riverbed, easily creating dead zones for suction in complex or uneven riverbed terrain, leading to incomplete dredging; second, during the dredging process, there is also the problem of silt diffusion caused by agitation, making it difficult to achieve both dredging and pollution prevention effects; third, the pumped mud-water mixture requires large sedimentation tanks or complex dewatering equipment for subsequent treatment, occupying a large area, with a cumbersome process, thus limiting the overall dredging efficiency.
[0005] In addition, whether it is mechanical dredging or pump dredging, a large amount of water in the collected sludge is transported together, which wastes transportation resources and increases subsequent treatment costs. How to achieve efficient separation of mud and water during the dredging process and return the separated clean water to the river channel to realize the recycling of resources is a technical problem that urgently needs to be solved in the field of river management. Summary of the Invention
[0006] To address the aforementioned technical problems, the present invention adopts the following technical solution: a silt removal device suitable for river management, comprising a main body for collecting silt, the main body including a river, and the main body being provided with a silt removal mechanism for cleaning silt and a moving mechanism for moving the silt removal mechanism, the moving mechanism including a frame.
[0007] Furthermore, two water collection tanks are fixedly installed in the underground part beside the river channel, and a water pump is fixedly installed in the water collection tank. A return water pipe is fixedly installed on the water pump and fixedly installed to the side of the river channel.
[0008] Furthermore, a side frame is fixedly installed on the water collection tank, a downward pressure column is slidably installed on the side frame, a downward pressure plate is fixedly installed on the downward pressure column, a downward pressure spring is provided between the downward pressure plate and the side frame, a downward switch is fixedly installed below the downward pressure plate, a sludge basket is placed on the downward pressure plate, and multiple holes are provided on the sludge basket.
[0009] Furthermore, a filter plate is fixedly installed on the water collection tank, and the filter plate has multiple holes. A float plate is slidably installed inside the water collection tank, and the float plate has several long grooves. A docking block is fixedly installed on the float plate. In the initial state, the docking block is located on the side frame.
[0010] The sludge is placed into the sludge discharge slope by the dredging mechanism, and eventually enters the sludge basket. The water in the sludge flows out into the water collection tank through the holes, while the sludge remains in the sludge basket. As more and more sludge accumulates in the sludge basket, it causes the lower pressure plate and lower pressure column to descend, compressing the lower pressure spring. When the lower switch contacts the docking block, the dredging mechanism stops working, and the sludge in the sludge basket is manually removed. As more and more water accumulates in the water collection tank, it causes the float plate and docking block to rise. When the docking block contacts the lower switch, the dredging mechanism stops working, and the water pump is started to pump the water in the water collection tank back into the river channel through the return pipe.
[0011] Furthermore, the moving mechanism includes an upper plate fixedly installed on the river channel, on which a sliding track and a mud discharge slope are fixedly installed, and on which a front docking plate and a rear docking plate are fixedly installed.
[0012] Furthermore, a movable frame is fixedly installed on the upper frame, a traveling shaft is rotatably installed on the movable frame, and rollers are fixedly installed on the traveling shaft. The rollers roll on a sliding track. A movable motor is fixedly installed on the upper frame, and the movable motor drives the traveling shaft to rotate through a belt drive. A front connecting rod and a rear connecting rod are fixedly installed on the upper frame.
[0013] The moving motor drives the traveling shaft and rollers to rotate via belt drive, thereby moving the upper plate along the sliding track. When the front docking rod contacts the front docking plate, the moving motor changes direction. When the rear docking rod contacts the rear docking plate, the moving motor changes direction.
[0014] Furthermore, the dredging mechanism includes an electric cylinder fixedly installed on the upper frame, a lifting block fixedly installed on the output end of the electric cylinder, a sewage pipe fixedly installed on the lifting block, a sewage pump fixedly installed on the sewage pipe, a descending plate fixedly installed on the sewage pump, two side cylinders fixedly installed below the descending plate, and a suction pipe fixedly installed below the sewage pump.
[0015] Furthermore, a side column is slidably installed inside the side cylinder, a compression spring is provided between the lowering plate and the upper frame, a sludge removal box is fixedly installed below the side column, a sludge removal motor is fixedly installed on the sludge removal box, a slope is provided below the sludge removal box, a sludge removal shaft is rotatably installed inside the sludge removal box, four sludge removal wheels are fixedly installed on the sludge removal shaft, and the sludge removal motor drives the sludge removal shaft to rotate via belt drive.
[0016] Furthermore, a three-part pipe is fixedly installed below the suction pipe, and the three-part pipe is slidably installed with the sludge removal box. An extension spring is provided between the three-part pipe and the sludge removal box.
[0017] The electric cylinder retracts, causing the lifting block, lowering plate, suction pipe, and three-section pipe to descend. The compression spring is compressed, which drives the sludge removal box to descend through the side cylinder and side column, bringing the sludge removal box into contact with the bottom of the river. Then, the lowering plate continues to descend, and the suction pipe and three-section pipe continue to descend, causing the three-section pipe to descend relative to the sludge removal box. The extension spring is compressed, allowing the three-section pipe to reach into the sludge removal box, bringing the end of the three-section pipe closer to the sludge, making it easier to remove the sludge. The sludge removal motor drives the sludge removal shaft and sludge removal wheel to rotate through the belt drive. The upper frame moves together with the upper plate. Through the rotation of the sludge removal wheel, in conjunction with the slope of the sludge removal box, the sludge is pushed into the sludge removal box. The sewage pump starts, pumping the sludge through the three-section pipe into the suction pipe and the sewage pipe, and then discharging the sludge into the mud discharge slope through the sewage pipe.
[0018] The beneficial effects of this invention compared with the prior art are: (1) The dredging mechanism set up in this invention drives the dredging box to descend and make close contact with the riverbed through an electric cylinder, forming a relatively closed working space. The dredging wheel pushes the silt into the box with the cooperation of the slope, and then the sludge is directly sucked in by the sludge pump through the extendable three-part pipe, which reduces the excessive stirring of the bottom mud during the dredging process, effectively prevents secondary pollution caused by the diffusion of pollutants, and ensures that there are no dead corners in the cleaning of complex riverbed terrain, and the dredging is more thorough; (2) In this invention, the collected silt is directly transported to the silt basket with holes. The water seeps out naturally under the action of gravity, is filtered by the filter plate and stored in the water collection tank. When the water level in the water collection tank reaches a certain height, the water pump can be automatically started to pump the clarified silt. Water is pumped back to the river through the return pipe. This process realizes the simultaneous dredging, mud-water separation and water resource reuse, which significantly reduces the total amount of silt transportation, saves transportation costs and promotes the benign cycle of water bodies; (3) The dredging mechanism set up in this invention adopts the synergistic effect of electric cylinder, compression spring and extension spring, so that the dredging box can adapt to the bottom height of the pool, ensuring that the three-part pipe is always close to the silt layer, improving the dredging efficiency, while avoiding hard collision between the three-part pipe and the bottom of the pool, and extending the service life; (4) The moving mechanism set up in this invention adopts the motor-driven roller to reciprocate on the sliding track, and with the limiting structure of the front and rear docking rods and docking plates, the dredging mechanism can automatically go back and forth to ensure that the silt at the bottom of the river is completely cleaned and avoids missed areas.

Detailed Implementation
[0028] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0029] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.
[0030] Example: Figures 1-8 As shown, a silt removal device suitable for river management includes a main body for collecting silt, the main body including a river 101, a dredging mechanism for cleaning silt and a moving mechanism for moving the dredging mechanism, the moving mechanism including a frame 206.
[0031] like Figures 2-4 As shown, two water collection tanks 106 are fixedly installed in the underground part next to the river channel 101. A water pump 110 is fixedly installed in the water collection tank 106. A return water pipe 109 is fixedly installed on the water pump 110. The return water pipe 109 is fixedly installed to the side of the river channel 101.
[0032] like Figures 2-4 As shown, a side frame 107 is fixedly installed on the water collection tank 106, a downward pressure column 113 is slidably installed on the side frame 107, a downward pressure plate 103 is fixedly installed on the downward pressure column 113, a downward pressure spring 102 is provided between the downward pressure plate 103 and the side frame 107, a downward switch 104 is fixedly installed below the downward pressure plate 103, and a sludge basket 105 is placed on the downward pressure plate 103, with multiple holes provided on the sludge basket 105.
[0033] like Figures 2-4 As shown, a filter plate 108 is fixedly installed on the water collection tank 106. The filter plate 108 has multiple holes. A float plate 111 is slidably installed inside the water collection tank 106. The float plate 111 has several long grooves. A docking block 112 is fixedly installed on the float plate 111. In the initial state, the docking block 112 is located on the side frame 107.
[0034] The sludge is placed into the sludge discharge slope 203 by the dredging mechanism, and finally enters the sludge basket 105. The water in the sludge will flow out into the water collection tank 106 through the holes, and the sludge will remain in the sludge basket 105. As more and more sludge is added to the sludge basket 105, it will cause the lower pressure plate 103 and the lower pressure column 113 to descend, and the lower pressure spring 102 will be compressed. When the lower switch 104 contacts the docking block 112, the dredging mechanism stops working, and the sludge in the sludge basket 105 is manually removed. As more and more water is added to the water collection tank 106, it will cause the float plate 111 and the docking block 112 to rise. When the docking block 112 contacts the lower switch 104, the dredging mechanism stops working, and the water pump 110 is started to pump the water in the water collection tank 106 back to the river channel 101 through the return water pipe 109.
[0035] like Figure 5 , Figure 6 As shown, the moving mechanism includes an upper plate 201 fixedly installed on the river channel 101, a sliding track 202 and a mud discharge slope 203 fixedly installed on the upper plate 201, and a front docking plate 210 and a rear docking plate 212 fixedly installed on the upper plate 201.
[0036] like Figure 5 , Figure 6 As shown, a movable frame 204 is fixedly installed on the upper frame 206, a traveling shaft 208 is rotatably installed on the movable frame 204, a roller 205 is fixedly installed on the traveling shaft 208, the roller 205 rolls on the sliding track 202, a movable motor 207 is fixedly installed on the upper frame 206, the movable motor 207 drives the traveling shaft 208 to rotate through belt drive, and a front docking rod 209 and a rear docking rod 211 are fixedly installed on the upper frame 206.
[0037] The moving motor 207 drives the walking shaft 208 and roller 205 to rotate via belt drive, thereby driving the upper plate 201 to move along the sliding track 202. When the front docking rod 209 contacts the front docking plate 210, the moving motor 207 changes direction. When the rear docking rod 211 contacts the rear docking plate 212, the moving motor 207 changes direction.
[0038] like Figure 7 , Figure 8 As shown, the dredging mechanism includes an electric cylinder 301 fixedly installed on the upper frame 206. A lifting block 302 is fixedly installed on the output end of the electric cylinder 301. A sewage pipe 304 is fixedly installed on the lifting block 302. A sewage pump 303 is fixedly installed on the sewage pipe 304. A descending plate 305 is fixedly installed on the sewage pump 303. Two side cylinders 306 are fixedly installed below the descending plate 305. A suction pipe 309 is fixedly installed below the sewage pump 303.
[0039] like Figure 7 , Figure 8 As shown, a side column 307 is slidably installed inside the side cylinder 306, a compression spring 308 is provided between the descending plate 305 and the upper frame 206, a sludge removal box 310 is fixedly installed below the side column 307, a sludge removal motor 313 is fixedly installed on the sludge removal box 310, a slope is provided below the sludge removal box 310, a sludge removal shaft 314 is rotatably installed inside the sludge removal box 310, four sludge removal wheels 315 are fixedly installed on the sludge removal shaft 314, and the sludge removal motor 313 drives the sludge removal shaft 314 to rotate through belt drive.
[0040] like Figure 7 , Figure 8As shown, a three-part pipe 311 is fixedly installed below the suction pipe 309. The three-part pipe 311 is slidably installed with the sludge removal box 310, and an extension spring 312 is provided between the three-part pipe 311 and the sludge removal box 310.
[0041] The electric cylinder 301 retracts, causing the lifting block 302, the lowering plate 305, the extraction pipe 309, and the three-part pipe 311 to descend. The compression spring 308 is compressed, which, through the side cylinder 306 and the side column 307, causes the sludge removal box 310 to descend, bringing it into contact with the bottom of the river channel 101. Subsequently, the lowering plate 305 continues to descend, as do the extraction pipe 309 and the three-part pipe 311, causing the three-part pipe 311 to descend relative to the sludge removal box 310. The extension spring 312 is compressed, allowing the three-part pipe 311 to reach the sludge removal box 310. In step 10, the end of the three-part pipe 311 is brought closer to the silt, making it easier to pump the silt away. The sludge removal motor 313 drives the sludge removal shaft 314 and the sludge removal wheel 315 to rotate via belt drive. The upper frame 206 moves together with the upper plate 201. Through the rotation of the sludge removal wheel 315, in conjunction with the slope of the sludge removal box 310, the silt is pushed into the sludge removal box 310. The sewage pump 303 starts and pumps the silt into the suction pipe 309 and the sewage discharge pipe 304 through the three-part pipe 311. The silt is then discharged into the mud discharge slope 203 through the sewage discharge pipe 304.
[0042] The working principle of the silt removal device for river management disclosed in this invention is as follows: the moving motor 207 drives the walking shaft 208 and the roller 205 to rotate through the belt drive, thereby driving the upper plate 201 to move along the sliding track 202. When the front docking rod 209 contacts the front docking plate 210, the moving motor 207 changes direction. When the rear docking rod 211 contacts the rear docking plate 212, the moving motor 207 changes direction. The electric cylinder 301 retracts, causing the lifting block 302, the lowering plate 305, the suction pipe 309, and the three-part pipe 311 to descend. The compression spring 308 is compressed, which, through the side cylinder 306 and the side column 307, drives the sludge removal box 310 to descend, bringing it into contact with the bottom of the river channel 101. The lowering plate 305 then continues to descend, as do the suction pipe 309 and the three-part pipe 311, causing the three-part pipe 311 to descend relative to the sludge removal box 310. The extension spring 312 is compressed, bringing the three-part pipe 311 into the sludge removal box 310, bringing its end closer to the sludge for easier removal. The sludge removal motor 313 drives the sludge removal shaft 314 and the sludge removal wheel 315 to rotate via belt drive. The upper frame 206 moves along with the upper plate 201. Through the rotation of the sludge removal wheel 315, combined with the slope of the sludge removal box 310, the sludge is pushed into the box. The sewage pump 30... 3. Upon startup, the sludge is pumped through the three-part pipe 311 into the suction pipe 309 and the sewage pipe 304. The sludge is then discharged through the sewage pipe 304 into the mud discharge slope 203, and finally enters the sludge basket 105. The water in the sludge flows out through the holes into the water collection tank 106, while the sludge remains in the sludge basket 105. As more and more sludge accumulates in the sludge basket 105, it causes the lower pressure plate 103 and the lower pressure column 113 to descend, compressing the lower pressure spring 102. When the lower switch 104 contacts the docking block 112, the sludge removal mechanism stops working, and the sludge in the sludge basket 105 is manually removed. As more and more water accumulates in the water collection tank 106, it causes the float plate 111 and the docking block 112 to rise. When the docking block 112 contacts the lower switch 104, the sludge removal mechanism stops working, and the water pump 110 is started to pump the water in the water collection tank 106 back into the river channel 101 through the return water pipe 109.
