Description

Technical Field

[0002] Dredging and sludge removal equipment is a specialized device used to remove silt, sand, debris, and sediment from the bottom of water. It works by rotating to break up the silt and debris into a slurry, which is then pumped through a suction pipe to a designated location. In urban drainage ditches, silt and sand gradually accumulate at the bottom due to water flow. Dredging and sludge removal equipment can regularly remove this silt and sand, ensuring the required water depth and width of the ditches and allowing water to flow normally to meet drainage needs.

[0003] A search revealed that the Chinese patent announcement number is CN221702545U. This utility model relates to the field of river dredging and sand excavation technology, and provides a dredging and sand excavation device, including a hull, a lifting component and a sediment tank on the hull, a suction component on the lifting component, the lifting component being used to drive the suction component to rise and fall relative to the hull, a dispersing component at the front end of the suction component, one end of the suction component extending underwater, and the other end connected to the sediment tank, a water filtering component inside the sediment tank, a water collecting hopper at the bottom of the sediment tank, a suction power component connected to the bottom of the water collecting hopper, and a drain pipe. This utility model can reduce the water content in the dredged sediment, reduce the workload of the hull, reduce the number of times the hull goes back and forth to unload sediment, and improve work efficiency. However, because the bottom of the river that needs to be dredged is relatively complex, the lifting component may experience jamming malfunctions when frequently rising and falling in complex water environments, affecting the normal operation of the suction component. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a dredging and desilting device, which aims to improve the problem in the prior art where the bottom of the river channel requiring dredging and desilting is relatively complex, and the lifting component frequently rises and falls in complex water environment, which may cause jamming and affect the normal operation of the suction component.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dredging and silt removal device, comprising a carrier plate, a sludge storage box fixedly connected to the inner bottom wall of the carrier plate, sludge pumps fixedly connected to the left and right sides of the inner bottom wall of the carrier plate, the output ends of the two sludge pumps respectively connected to the left and right sides of the sludge storage box, the output ends of the two sludge pumps respectively connected to elbow connectors, the bottom ends of the two elbow connectors respectively penetrating the left and right sides of the bottom wall of the carrier plate, the bottom ends of the two elbow connectors respectively connected to telescopic hoses, the bottom ends of the two telescopic hoses respectively connected to metal connecting cylinders, the interiors of the two metal connecting cylinders respectively fixedly connected to sealing barrels, the interiors of the two sealing barrels respectively fixedly connected to drive motors, the output ends of the two drive motors respectively penetrating the bottoms of the two sealing barrels and fixedly connected to sliding brackets, the exteriors of the two sliding brackets respectively fixedly connected to reamers, rotating components provided between the adjacent metal connecting cylinders and sliding brackets, and a width adjustment mechanism provided on the exterior of the carrier plate.

[0006] The above technical solution achieves efficient cutting, stirring of silt, and flexible and precise suction by using a drive motor to rotate the sliding bracket and cutter, in conjunction with a sludge pump to suck silt through elbow connectors, telescopic hoses and metal connecting cylinders, and by using rotating components to ensure smooth rotation during the sludge suction process. This effectively improves the underwater environment, restores the normal use function of the water area, and enhances the efficiency and quality of dredging operations.

[0007] As a further description of the above technical solution:

[0008] The width adjustment mechanism includes two main supports, with adjacent sides of the two main supports fixedly connected to the front and rear sides of the carrier plate, respectively. Sliding grooves are fixedly connected to the inner top and bottom walls of both main supports. Sub-supports are provided at the left and right ends of the interior of each of the two main supports. Two slide rails are fixedly connected to the top and bottom walls of each of the multiple sub-supports. The multiple sub-supports are slidably connected to the left and right ends of the inner walls of the two main supports via multiple sliding grooves and slide rails. Electric telescopic rods are fixedly connected to the inner top walls of each of the multiple sub-supports. Lifting locks are fixedly connected to the output ends of each of the multiple electric telescopic rods. Electric wheels are fixedly connected to the bottom ends of the multiple sub-supports and the opposite bottom ends.

[0009] The above technical solution controls the locking state of the lifting lock and the carrier plate by means of an electric telescopic rod. The auxiliary support slides with the help of slide rails and sliding grooves. Combined with electric wheel drive, it realizes convenient adjustment of the carrier plate width, enhances the mobility of the device in different terrains, improves the adaptability of the overall device to complex working conditions, and ensures efficient dredging operations.

[0010] As a further description of the above technical solution:

[0011] Both of the rotating components include T-shaped rings, which are fixedly connected to the top of the two sliding brackets respectively. The bottom of the two metal connecting cylinders is provided with T-shaped grooves, and the two T-shaped rings are slidably connected inside the two T-shaped grooves respectively.

[0012] Through the above technical solution, the T-ring and T-slot in the rotating assembly cooperate to realize the rotational connection of the sliding bracket at the bottom of the metal connecting cylinder, so that the sliding bracket can rotate around the axis in a stable manner, ensuring that the reamer can rotate flexibly during operation.

[0015] The above technical solution involves reinforcing ribs that are fixedly connected in a cross pattern to the outer walls of the main support and the secondary support, which can enhance the structural strength of the main support and the secondary support.

[0016] As a further description of the above technical solution:

[0017] A signal receiver is fixedly connected to the top of the mud storage tank, and multiple signal amplification rings are fixedly connected to the outer top of the signal receiver.

[0018] Through the above technical solution: the signal receiver is used to receive external control signals, and the signal amplification ring at the top can enhance the strength and stability of the signal received by the signal receiver.

[0019] As a further description of the above technical solution:

[0020] The inner bottom wall of the carrier plate is fixedly connected to the left and right ends with lifting rings, both of which are made of stainless steel.

[0021] The above technical solution involves using stainless steel lifting rings fixed to the left and right ends of the inner bottom wall of the carrier plate. This allows the entire device to be lifted using cranes or other lifting equipment when the dredging device needs to be moved to a different work site or installed or repaired.

[0025] As a further description of the above technical solution:

[0026] The exterior of each of the electric wheels is provided with anti-slip grooves, which are equidistantly spaced in a herringbone pattern.

[0027] The above technical solution involves anti-slip grooves that are equidistantly spaced and arranged in a herringbone pattern on the outside of the electric wheel, which increases the friction between the electric wheel and the ground.

Detailed Implementation

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figure 1 , Figure 2 and Figure 5 An embodiment of this utility model provides a dredging and silt removal device, including a carrier plate 1, a sludge storage box 3 fixedly connected to the inner bottom wall of the carrier plate 1, sludge pumps 4 fixedly connected to the left and right sides of the inner bottom wall of the carrier plate 1, the output ends of the two sludge pumps 4 respectively connected to the left and right sides of the sludge storage box 3, the output ends of the two sludge pumps 4 respectively connected to elbow connectors 5, the bottom ends of the two elbow connectors 5 respectively penetrating the left and right sides of the bottom wall of the carrier plate 1, the bottom ends of the two elbow connectors 5 respectively connected to telescopic hoses 6, the bottom ends of the two telescopic hoses 6 respectively connected to metal connecting cylinders 7, the inside of the two metal connecting cylinders 7 fixedly connected to sealing barrels 8, the inside of the two sealing barrels 8 fixedly connected to drive motors 9, the output ends of the two drive motors 9 respectively penetrating the bottom of the two sealing barrels 8 and fixedly connected to sliding brackets 10, the outside of the two sliding brackets 10 fixedly connected to reamers 11, the adjacent metal connecting cylinders 7 and sliding brackets 10 are provided with rotating components, and the outside of the carrier plate 1 is provided with a width adjustment mechanism 2.

[0041] Specifically, during dredging, the carrier plate 1 is placed in the water area requiring dredging, and then two drive motors 9 are started. Each drive motor 9 drives a connected sliding bracket 10 to rotate. Since a cutter 11 is fixedly connected to the outside of the sliding bracket 10, the cutter 11 rotates at high speed. The rotating cutter 11 cuts and agitates the silt and impurities at the bottom of the water, loosening them. At this time, two sludge pumps 4 form suction channels through connected elbow connectors 5, telescopic hoses 6, and metal connecting cylinders 7. Under the suction of the sludge pumps 4, the silt and impurities agitated by the cutter 11 are sequentially drawn into the sludge pumps 4 via the metal connecting cylinder 7, telescopic hose 6, and elbow connector 5. The sealing barrel 8 inside the metal connecting cylinder 7 seals and protects the drive motor 9, preventing silt and water from entering the motor and affecting its normal operation. The telescopic hose 6 can adapt to different working depths and position changes, making sludge suction more flexible and convenient. The elbow connector 5 can smoothly remove the silt... The sludge is transported to the sludge pump 4. The sludge pumped out by the sludge pump 4 is transported to the sludge storage tank 3 through its output end for storage. As the operation continues, a large amount of sludge will gradually accumulate in the sludge storage tank 3. When the sludge storage tank 3 is full, the tail end of the metal connecting cylinder 7 is connected to the dredging vehicle, one sludge pump 4 is turned off, and then the other sludge pump 4 is driven in reverse. At this time, the function of the sludge pump 4 changes from suction to discharge. Under the action of its reverse driving force, the sludge in the sludge storage tank 3 will flow in reverse along the previous suction channel, passing through the sludge pump 4, the elbow connector 5, the telescopic hose 6 and the metal connecting cylinder 7 in sequence, and finally being discharged into the dredging vehicle. In the whole process, the rotating components set between the two metal connecting cylinders 7 and the sliding support 10 ensure that the sliding support 10 can drive the cutter 11 to rotate smoothly, reduce frictional resistance, improve the working efficiency and stability of the device, and thus effectively realize the dredging and cleaning of sludge in the water area, improve the underwater environment, and ensure the normal use function of the water area.

[0042] Reference Figure 2 , Figure 4 and Figure 5 The width adjustment mechanism 2 includes two main supports 201. The adjacent sides of the two main supports 201 are fixedly connected to the front and rear sides of the carrier plate 1, respectively. The inner top and bottom walls of the two main supports 201 are fixedly connected to sliding grooves 202. The left and right ends of the interior of the two main supports 201 are provided with auxiliary supports 203. The top and bottom walls of the multiple auxiliary supports 203 are fixedly connected to two slide rails 204. The multiple auxiliary supports 203 are slidably connected to the left and right ends of the inner walls of the two main supports 201 through multiple sliding grooves 202 and slide rails 204, respectively. The inner top walls of the multiple auxiliary supports 203 are fixedly connected to electric telescopic rods 205. The output ends of the multiple electric telescopic rods 205 are fixedly connected to lifting locks 206. The bottom ends of the multiple auxiliary supports 203 and the bottom ends of the opposite sides are fixedly connected to electric wheels 207.

[0043] Specifically, when the width of the carrier plate 1 needs to be adjusted, the electric telescopic rod 205 is activated. The electric telescopic rod 205 retracts, causing the lifting lock 206 to rise, thus releasing it from the locked state with the carrier plate 1. At this time, the movement restrictions of the multiple auxiliary supports 203 within the main support 201 are lifted. Since the top and bottom walls of the auxiliary supports 203 are fixedly connected to slide rails 204, and the inner top and bottom walls of the main support 201 are fixedly connected to matching sliding grooves 202, under power drive, the auxiliary supports 203 can slide on the left and right ends of the inner wall of the main support 201 through the cooperation of the slide rails 204 and the sliding grooves 202. According to the required width adjustment requirements, the auxiliary supports 203 can be controlled to move inward or outward. Once the width is adjusted to the appropriate position, the electric telescopic rod 205 is activated again to extend it. The lifting lock 206 descends and re-locks the carrier plate 1, locking the auxiliary support 203 to the carrier plate 1 again to ensure the stability of the carrier plate 1's width. During the movement of the device, the rotation of the electric wheel 207 is controlled to enable the entire device to move flexibly on different terrains. The electric wheel 207 can provide stable driving force and steering force according to the actual working site conditions, enabling the device to accurately reach the designated dredging and silt removal location. Furthermore, it can be moved and adjusted within a small range as needed during operation, thereby improving the adaptability and operational efficiency of the entire dredging and silt removal device under different working conditions.

[0044] Reference Figure 1 , Figure 2 and Figure 5 Both rotating components include T-shaped rings 12, which are fixedly connected to the tops of the two sliding supports 10. T-shaped grooves 13 are provided at the bottoms of the two metal connecting cylinders 7, and the two T-shaped rings 12 are slidably connected within the two T-shaped grooves 13. Multiple reinforcing ribs 14 are fixedly connected to the outer walls of the two main supports 201 and the outer walls of the multiple auxiliary supports 203, and these reinforcing ribs 14 are fixedly connected in a crisscross pattern to the outer walls of the two main supports 201 and the multiple auxiliary supports 203. A signal receiver 15 is fixedly connected to the top of the mud storage tank 3, and multiple signal amplification rings 16 are fixedly connected to the outer top of the signal receiver 15.

[0045] Specifically, the T-ring 12 and T-groove 13 in the rotating assembly cooperate to achieve the rotational connection of the sliding bracket 10 at the bottom of the metal connecting cylinder 7, so that the sliding bracket 10 can rotate around the axis in a stable manner, ensuring that the reamer 11 can rotate flexibly during operation. The reinforcing ribs 14 are fixedly connected to the outer walls of the main bracket 201 and the secondary bracket 203 in a cross pattern, which can enhance the structural strength of the main bracket 201 and the secondary bracket 203. The signal receiver 15 is used to receive external control signals, and the signal amplification ring 16 at its top can enhance the strength and stability of the signal received by the signal receiver 15.

[0046] Reference Figure 1 The inner bottom wall of the carrier plate 1 is fixedly connected to the left and right ends of the lifting rings 17, and both lifting rings 17 are made of stainless steel; the top of the two mud pumps 4 is provided with heat dissipation slits 18, and the outer perimeter of the two mud pumps 4 is fixedly connected with heat dissipation fins 19; the outer perimeter of the multiple electric wheels 207 is provided with anti-slip grooves 20, and the anti-slip grooves 20 are equidistantly spaced in a herringbone pattern.

[0047] Specifically, the lifting ring 17 is made of stainless steel and is fixed to the left and right ends of the inner bottom wall of the carrier plate 1. When the dredging device needs to be moved to a different work site or installed or repaired, the entire device can be lifted by lifting equipment such as a crane through the lifting ring 17. The heat dissipation slit 18 on the top of the dredging pump 4 and the heat dissipation fins 19 on the outer periphery of the dredging pump 4 allow heat to be dissipated through air convection. The anti-slip groove 20 is opened on the outside of the electric wheel 207 and is equidistant in a herringbone pattern, which can increase the friction between the electric wheel 207 and the ground.

[0048] Working Principle: During dredging, the carrier plate 1 is placed in the water area requiring dredging. Then, two drive motors 9 are started, each driving a connected sliding support 10 to rotate. Since a cutter 11 is fixedly connected to the outside of the sliding support 10, the cutter 11 rotates at high speed. The rotating cutter 11 cuts and agitates the silt and impurities at the bottom of the water, loosening them. At this time, two sludge pumps 4 form suction channels through connected elbow connectors 5, telescopic hoses 6, and metal connecting cylinders 7. Under the suction of the sludge pumps 4, the silt and impurities agitated by the cutter 11 are sequentially drawn into the sludge pumps 4 via the metal connecting cylinder 7, telescopic hose 6, and elbow connector 5. The sealing barrel 8 inside the metal connecting cylinder 7 seals and protects the drive motor 9, preventing silt and water from entering the motor and affecting its normal operation. The telescopic hose 6 can adapt to different working depths and positions. The change in position makes the sludge suction operation more flexible and convenient. The elbow connector 5 can smoothly transport the sludge to the sludge pump 4. The sludge pumped out by the sludge pump 4 will be transported to the sludge storage tank 3 through its output end for storage. As the operation continues, a large amount of sludge will gradually accumulate in the sludge storage tank 3. When the sludge storage tank 3 is full, the tail end of the metal connecting cylinder 7 is connected to the sludge truck, one sludge pump 4 is turned off, and then the other sludge pump 4 is driven in reverse. At this time, the function of the sludge pump 4 changes from suction to discharge. Under the action of its reverse driving force, the sludge in the sludge storage tank 3 will flow in reverse along the previous suction channel, passing through the sludge pump 4, elbow connector 5, telescopic hose 6 and metal connecting cylinder 7 in sequence, and finally being discharged into the sludge truck. In the whole process, the rotating components set between the two metal connecting cylinders 7 and the sliding bracket 10 ensure that the sliding bracket 10 can drive the reamer 11 to rotate smoothly and reduce frictional resistance.

[0049] Furthermore, when the width of the carrier plate 1 needs to be adjusted, the electric telescopic rod 205 is activated. The electric telescopic rod 205 retracts, causing the lifting lock 206 to rise, thus releasing it from its locked state with the carrier plate 1. At this time, the movement restrictions of the multiple auxiliary supports 203 within the main support 201 are lifted. Since the top and bottom walls of the auxiliary supports 203 are fixedly connected to slide rails 204, and the inner top and bottom walls of the main support 201 are fixedly connected to matching sliding grooves 202, under power drive, the auxiliary supports 203 can move within the main support 201 through the cooperation of the slide rails 204 and the sliding grooves 202. The inner wall slides to the left and right ends. According to the required width adjustment, the auxiliary support 203 is controlled to slide inward or outward to the appropriate position. After the width is adjusted to the right position, the electric telescopic rod 205 is activated again to extend it. The lifting lock 206 descends and locks the carrier plate 1 again, locking the auxiliary support 203 and the carrier plate 1 again to ensure the width of the carrier plate 1 is stable. During the movement of the device, the rotation of the electric wheel 207 is controlled to realize the flexible movement of the entire device on different terrains. The electric wheel 207 can provide stable driving force and steering force according to the actual working site conditions.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
