Description

Technical Field

[0001] This utility model relates to the field of river management technology, specifically to a river management and dredging device. Background Technology

[0002] Riverbed siltation refers to the accumulation of sediments such as mud, sand, and garbage in the riverbed. These sediments can affect the river's flow capacity, water quality, and ecological environment. The silt in riverbeds mainly originates from upstream erosion, rainfall, soil loss, agricultural activities, and urban drainage. As siltation increases, the river's navigation capacity, flood discharge capacity, and water quality can be severely impacted. Especially during floods, river blockages can trigger even greater disasters. With the development of artificial intelligence and automated equipment, river dredging devices can utilize high-tech equipment such as robots and underwater drones for automated operations, greatly improving operational efficiency.

[0003] Patent specification CN 113374013 A discloses a river dredging and cleaning device. The device comprises an installation box with an installation plate fixed to its outer wall; an installation pipe positioned below the installation plate, with a rod sleeve installed inside the pipe and a telescopic rod connected to its front end; a connecting rod positioned on one side of the telescopic rod, with a dredging shell fixed below it; a drive motor installed inside the dredging shell, with a fixing plate fixed to one side of the drive motor; and an installation rod positioned at the front end of the drive motor, with a breaking blade mounted on its outer wall. This river dredging and cleaning device features a rod sleeve, allowing the telescopic rod to drive the dredging shell, thereby cleaning the silt from the riverbed. The dredging shell also confines the silt, preventing it from flowing with the river.

[0004] However, during the implementation of the relevant technology, the above-mentioned river management and dredging device was found to have the following problems: when in use, silt easily clogs the guide pipe, and when filtering silt, silt also easily clogs the filter holes, affecting the filtration effect. Therefore, we have proposed a river management and dredging device. Utility Model Content

[0006] The technical solution of this utility model is as follows:

[0007] A river dredging and desilting device includes a main body, casters, and a mounting platform. A movable platform is mounted on the bottom of the main body, and casters are symmetrically mounted on the bottom of the movable platform. A baffle is provided on the side of the main body, and the mounting platform is located at the top of the baffle. A servo motor is mounted at the top of the mounting platform, and the output shaft of the servo motor passes through the outer wall of the mounting platform and is connected to a lead screw. A movable frame is movably mounted on the outer wall of the lead screw. Limit grooves are symmetrically provided on the outer wall of the baffle, and one end of the movable frame extends through the limit groove to the bottom of the baffle. A winch is mounted at the bottom of the movable frame, and a waterproof motor is mounted at the top of the winch. The drive shaft of the waterproof motor passes through the outer wall of the winch and extends into the winch, connecting to an auger. A first water pump is mounted at the top of the movable platform, and the output end of the first water pump is connected to an input pipe. One end of the input pipe passes through the top of the winch and extends into the winch. A filter chamber is provided inside the main body. A collection chamber is provided on the side of the filter chamber. The first water pump is connected to the filter chamber through a guide pipe. The inner wall of the filter chamber is symmetrically provided with second sliding grooves. A filter plate is movably installed in the filter chamber through the second sliding grooves. Second sliders are symmetrically provided on both sides of the filter plate. Telescopic rods are installed on the inner walls of the second sliding grooves. Springs are installed on the outer walls of the telescopic rods. One end of the telescopic rod is connected to the outer wall of the second slider. A drive motor is installed on the outer wall of the device body. The drive shaft of the drive motor passes through the outer wall of the device body and is connected to a first striking block. The end of the first striking block away from the drive motor passes through the inner wall of the filter chamber and extends to the outer wall of the device body, where it is connected to a driving gear. A second striking block is movably installed on the inner wall of the filter chamber. One end of the second striking block passes through the inner wall of the filter chamber and through the outer wall of the device body, where it is connected to a driven gear. The driving gear and the driven gear mesh with each other for transmission. A control panel is provided on the outer wall of the device body.

[0008] Preferably, a second water pump is installed on the outer wall of the mobile platform. One end of the second water pump is connected to the bottom end of the filter chamber through a suction pipe, and the output end of the second water pump is connected to a discharge pipe.

[0009] Preferably, the filter plate is inclined and located on the inner wall of the filtration chamber, and a channel is provided between the filtration chamber and the collection chamber.

[0010] Preferably, a transmission block is provided at the bottom of the filter plate, and the first striking block and the second striking block are located directly below the transmission block.

[0011] Preferably, the inner wall of the collection cavity is symmetrically provided with first sliding grooves, and a collection box is movably installed in the collection cavity through the first sliding grooves. First sliders are symmetrically provided on both sides of the collection box, and the first sliding grooves and the first sliders are matched with each other.

[0012] Preferably, the second slider has a rectangular block structure, and the second slider and the second groove fit together.

[0013] Preferably, the outer wall of the lead screw is provided with external threads, and the top of the movable frame is provided with a screw hole that matches the external threads.

[0014] Preferably, the auger has a conical structure, and the auger fits into the inner wall of the auger.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] In this invention, the device is equipped with casters, a movable frame, and a servo motor. During use, the casters move the main body to the riverbank, and brake pads secure the casters. The servo motor is activated via the control panel, driving a lead screw to rotate. A threaded hole in the center of the movable frame further rotates the frame, and a limiting groove limits its movement, causing the auger to descend. Once the auger reaches the riverbed, a waterproof motor is activated to rotate the auger. The auger and auger work together to agitate and transfer the silt to the top of the auger. A first water pump then draws the silt from the top of the auger through an input pipe and a guide pipe, transferring it to the filter chamber where it falls onto the top of the filter plate. This structure allows for adjustment of the auger's position based on the silt depth, and facilitates silt agitation and cleaning.

[0017] In this invention, a filter plate, a driving gear, and a driven gear are used to filter sludge. Simultaneously, a drive motor rotates the driving gear, and the meshing of the driving and driven gears drives the first and second striking blocks to rotate in opposite directions. As the first and second striking blocks rotate, they intermittently strike the bottom of the transmission block. During this striking, the filter plate moves up and down under the limiting action of the second slider and the second slide groove, compressing the telescopic rod and the servo motor. The elastic force generated by the spring deformation causes the filter plate to vibrate rapidly, preventing sludge from clogging the filter plate. The filter plates are inclined and located on the inner wall of the filtration chamber, causing the sludge to fall into the collection box inside the collection chamber under vibration. The clean water after sludge filtration flows to the bottom of the filtration chamber, where a second water pump is started to extract the sludge through the suction pipe and discharge it into the river through the discharge pipe. Once the collection box is full of sludge, it is slid out from the rear of the device body through the first chute and the first slider for processing. This structure can prevent the filter holes on the outer wall of the filter plate from being blocked by vibration, separate the sludge and water for processing, avoid water waste, and provide unified treatment of the sludge.

The universal wheels 3 are fixed by the brake pads. The servo motor 7 is started by the control panel 34. The servo motor 7 drives the lead screw 8 to rotate. The threaded hole in the middle of the movable frame 6 drives the movable frame 6 to rotate. The limiting groove 21 limits the movable frame 6, causing the movable frame 6 to move the auger drum 10 down. When the auger drum 10 moves to the bottom of the riverbed, the waterproof motor 9 is started to drive the auger 11 to rotate. The auger drum 10 and the auger 11 work together to stir the silt and transfer it to the top of the auger drum 10. The first water pump 12 is started to suck the silt at the top of the auger drum 10 into the input pipe 17 and then transfer it to the inside of the filter chamber 19 through the guide pipe 16 and drop it to the top of the filter plate 18. When using this structure, the position of the auger drum 10 can be adjusted according to the depth of the silt. At the same time, it can stir the silt and facilitate silt removal.

[0030] Example 2: A second water pump 13 is installed on the outer wall of the mobile platform 2. One end of the second water pump 13 is connected to the bottom end of the filter chamber 19 through the suction pipe 14, and the output end of the second water pump 13 is connected to the discharge pipe 15.

[0031] In this embodiment, the filter plate 18 is inclined and located on the inner wall of the filter chamber 19, and a channel is provided between the filter chamber 19 and the collection chamber 20.

[0032] In this embodiment, a transmission block 33 is provided at the bottom of the filter plate 18, and the first striking block 30 and the second striking block 35 are located directly below the transmission block 33.

[0033] In this embodiment, the inner wall of the collection cavity 20 is symmetrically provided with a first sliding groove 22, and the collection cavity 20 is movably installed with a collection box 23 through the first sliding groove 22. The two sides of the collection box 23 are symmetrically provided with a first slider 24, and the first sliding groove 22 and the first slider 24 are matched with each other.

[0034] In this embodiment, the second slider 25 has a rectangular block structure, and the second slider 25 and the second slide groove 28 fit together.

[0035] Specific examples Figure 1 , Figure 4 and Figure 5As shown, when using this structure, the filter plate 18 filters the sludge. Simultaneously, the drive motor 29 is activated, driving the drive gear 31 to rotate. The drive gear 31 and driven gear 32 mesh together, driving the first striking block 30 and the second striking block 35 to rotate in opposite directions. As the first and second striking blocks 30 and 35 rotate, they intermittently strike the bottom of the transmission block 33. During this striking, the filter plate 18 moves up and down under the limiting action of the second slider 25 and the second slide groove 28, compressing the telescopic rod 26 and the servo motor 7. The elastic force generated by the deformation of the spring 27 causes the filter plate 18 to vibrate rapidly, preventing sludge from clogging the filter holes of the filter plate 18. Because the filter plate 18 is inclined and located on the inner wall of the filter chamber 19, the sludge falls into the collection box 23 inside the collection chamber 20 under vibration. The clean water after sludge filtration flows to the bottom of the filter chamber 19. The second water pump 13 is started to draw it out through the suction pipe 14 and then discharge it into the river through the discharge pipe 15. When the collection box 23 is full of sludge, the collection box 23 is slid out from the tail of the device body 1 through the first chute 22 and the first slider 24 for processing. This structure can prevent the filter holes on the outer wall of the filter plate 18 from being blocked by vibration, separate the sludge and water for processing, avoid water waste, and treat the sludge in a unified manner.

[0036] Working principle: In use, the main body 1 of the device is moved to the riverbank by the casters 3 and fixed by the brake pads. The servo motor 7 is started by the control panel 34, which drives the lead screw 8 to rotate. The threaded hole in the middle of the movable frame 6 drives the movable frame 6 to rotate. The limiting groove 21 limits the movement of the movable frame 6, causing the movable frame 6 to move the auger drum 10 downward. Once the auger drum 10 has moved to the bottom of the riverbed, the waterproof motor 9 is started to drive the auger 11 to rotate. The auger drum 10 and the auger 11 work together to remove the silt. The stirring spiral conveys the sludge to the top of the auger 10. The first water pump 12 is activated, drawing the sludge from the top of the auger 10 through the input pipe 17 and then through the guide pipe 16 to the interior of the filter chamber 19, where it falls onto the top of the filter plate 18. The filter plate 18 filters the sludge. Simultaneously, the drive motor 29 is activated, driving the drive gear 31 to rotate. The drive gear 31 and driven gear 32 mesh together, driving the first striking block 30 and the second striking block 35 to rotate in opposite directions. As the first and second striking blocks 30 and 35 rotate, intermittent striking occurs. At the bottom of the moving block 33, when struck, the filter plate 18 moves up and down under the limiting action of the second slider 25 and the second slide groove 28, compressing the telescopic rod 26 and the servo motor 7. The elastic force generated by the deformation of the spring 27 causes the filter plate 18 to vibrate rapidly, preventing sludge from clogging the filter holes of the filter plate 18. Since the filter plate 18 is inclined and located on the inner wall of the filter chamber 19, the sludge falls into the collection box 23 set inside the collection chamber 20 under vibration. The clean water after filtering the sludge flows to the bottom of the filter chamber 19, and the second water pump 13 is started to pump water through the suction pipe 1. 4. Extract the silt and discharge it into the river through the discharge pipe 15. When the silt in the collection box 23 is full, slide the collection box 23 out from the tail of the device body 1 through the first chute 22 and the first slider 24 for processing. This device can easily absorb the silt at the bottom of the riverbed and stir it to avoid the silt lumps from being too large and blocking the input pipe 17, thereby improving the dredging speed. At the same time, when filtering the silt, vibration can prevent the filter holes set on the outer wall of the filter plate 18 from being blocked, so that the silt and water are treated separately, avoiding the waste of water resources, and the silt is treated uniformly.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
