[0002] River dredging is an important part of maintaining water environment quality and protecting the health of river ecosystems. If river silt cleaning is not done well, it will lead to a decrease in the river's flood-carrying capacity, a reduction in biodiversity, deterioration of river water quality, and stagnation of river flow, which will reduce the overall ecological environment quality of the river.

[0030] Embodiment 1

[0031] like Figure 1-3 As shown, this embodiment provides a river channel dredging device, which includes:

[0032] The vehicle body 1, in some embodiments, includes two tracks 101 and a driving device for driving the tracks 101 to move, and a vehicle plate 102 is arranged above the tracks 101;

[0033] The sludge dewatering assembly 2 is arranged on the vehicle body 1 and fixed above the vehicle plate 102 by support rods 8. The support rods 8 on both sides are distributed in an eight-shaped shape. The output end of the sludge dewatering assembly 2 is connected to a sludge discharge pipe 9, through which the dehydrated sludge is discharged to reduce the weight of the sludge and facilitate its subsequent transportation or processing;

[0034] The silt extraction component 3 is used to extract the silt in the river channel. The silt extraction component 3 is connected to the input end of the silt dehydration component 2 to transport the extracted silt to the silt dehydration component 2 for dehydration;

[0035] Among them, the sludge dewatering component 2 has a water outlet at the bottom. After the sludge dewatering component 2 separates the sludge and the accompanying water, the water flows out through the water outlet. A water collecting tank 4 is arranged below the dewatering port 23. The water collecting tank 4 is connected to a high-pressure water pump 5. The high-pressure water pump 5 is connected to at least one group of high-pressure nozzles 6. The spray direction of the high-pressure nozzles 6 is toward the suction end of the sludge extraction component 3.

[0036] During actual use, the silt extraction component 3 lifts the silt in the river channel and transports it to the silt dehydration component 2 for solid-liquid separation. The separated water enters the water collecting tank 4 through the dehydration port 23, and the dehydrated silt is discharged from the silt discharge pipe 9. The water in the water collecting tank 4 is transported to the high-pressure nozzle 6 through the high-pressure water pump 5. The high-pressure nozzle 6 faces the suction end, and the high-pressure nozzle 6 disperses the more stubborn silt that has condensed into blocks, which is convenient for subsequent suction by the silt extraction component 3. The sucked silt is dehydrated again, and the above steps are repeated to recycle the water contained in the silt, saving a lot of water resource costs and avoiding waste of water resources.

[0037] In some embodiments, the sludge dewatering assembly 2 includes a shell 21, which is a hollow cylindrical structure. A rotatable squeezing screw 22 is arranged in the shell 21. The squeezing screw 22 is a variable pitch design. The water attached to the sludge is separated by squeezing in cooperation with the inner wall of the shell 21. A dewatering port 23 is opened at the end of the shell 21. The dewatering port 23 is detachably connected to a silt filter 24. The silt filter 24 filters the water in the sludge and discharges it from the dewatering port 23 to the inside of the water collecting tank 4.

[0038] In some embodiments, a plurality of connecting rods 25 are fixedly connected in the shell 21, and a driven bearing 26 is commonly connected at the center of the connecting rods 25. One end of the squeezing screw 22 is connected to the inner ring of the driven bearing 26, and the other end of the squeezing screw 22 passes through the shell 21 and is connected to a drive motor 27. The driven bearing 26 is supported by the connecting rods 25 to facilitate the passage of sludge between the connecting rods 25. The squeezing screw 22 is driven by the drive motor 27 to rotate, and the sludge is transported while the water attached to it is squeezed out during the rotation.

[0039] In some embodiments, the silt extraction assembly 3 includes a silt extraction pipe 31, on which a silt extraction pump 32 is provided, and the output end of the silt extraction pump 32 is connected to a conveying pipe 33, and the conveying pipe 33 is connected to the sludge dewatering assembly 2; wherein, the conveying pipe 33 is fixed above the vehicle plate 102 by support rods 8, and the support rods 8 on both sides are distributed in an eight-shaped shape.

[0040] In some embodiments, a high-pressure pipe 7 is commonly connected between the high-pressure water pump 5 and the high-pressure nozzle 6. The high-pressure pipe 7 passes through the vehicle plate 102 and is connected to the above-mentioned high-pressure nozzle 6. The high-pressure pipe 7 is used as a receiving part to transport the water in the water collecting tank 4 to the high-pressure nozzle 6, and the high-pressure nozzle 6 disperses the silt and then extracts it.

[0041] Optionally, a crushing assembly may be provided at the bottom of the sludge extraction pipe 31 , and the crushing assembly may be used to break up the hard debris in the sludge, which is then transported to the interior of the sludge dewatering assembly 2 by the high-pressure water pump 5 .

[0042] It is worth noting that, in this embodiment, the silt extraction pipe 31 and the conveying pipe are both made of hard materials.

[0043] The device is also provided with a controller, through which the operation of the driving motor 27, the silt extraction pump 32 and the high-pressure water pump 5 is controlled.

[0044] Working principle of this device:

[0045] The vehicle body 1 drives the silt extraction pipe 31 to extract the silt in various areas of the river channel. The silt is transported to the conveying pipe 33 through the silt extraction pump 32, and then flows through the connecting rod 25 and is further transported by the squeezing screw 22. The silt is squeezed and dehydrated during the transportation process of the squeezing screw 22. The separated water flows into the water collecting tank 4 under the filtration of the silt blocking filter 24, and the dehydrated silt is transported to other equipment through the drainage pipe for transfer or further processing.

[0046] In the process of pumping out silt, if there is silt that is hard to pump out because it is hard to pump out, the high-pressure water pump 5 is used to disperse the stubborn silt, which is then further pumped out by the sludge dewatering assembly 2. The high-pressure nozzle 6 can also be used to flush the silt and gather it together to facilitate centralized extraction by the silt pumping pipe 31.

[0047] Embodiment 2

[0048] like Figure 4 As shown, this embodiment provides a river channel desilting device, and other structures are the same as those of the first embodiment. The only difference is that in this embodiment, the silt extraction pipe 31 includes an upper pipe 311 and a lower pipe 312, and the lower pipe 312 is located below the upper pipe 311 and can be moved up and down.

[0049] In some embodiments, the upper pipe 311 and the lower pipe 312 are fixedly connected to the east with a connection plate 314, and the two connection plates 314 are commonly connected with a bellows 313. At least one set of telescopic kits is arranged between the two connection plates 314. The bellows 313 is a tubular elastic sensitive element with telescopic function. When facing a pit or other special circumstances, there is a certain distance between the silt extraction pipe 31 and the pit, and the silt in the pit cannot be extracted. At this time, the distance between the upper pipe 311 and the lower pipe 312 is adjusted by the telescopic kit, and the bellows 313 is used as a receiving part of the two to adjust the position between the bottom of the lower pipe 312 and the silt to be sucked.

[0050] In some embodiments, the telescopic kit includes a hollow rod 315 located at the bottom, a rotatable nut 317 is arranged above the hollow rod 315, and a threaded rod 316 located at the top, and the threaded rod 316 and the nut 317 are threadedly connected to realize the up and down sliding setting between the threaded rod 316 and the hollow rod 315. When it is necessary to adjust the distance between the upper pipe 311 and the lower pipe 312, the nuts 317 in the two telescopic kits are rotated at the same time. During the connection between the nuts 317 and the threaded rod 316, the threaded rod 316 slides in the hollow rod 315, so as to adjust the distance between the upper pipe 311 and the lower pipe 312, so that the bottom of the lower pipe 312 is close to the sludge to be sucked, and the sludge in the pit is extracted.

[0051] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
