Description

Technical Field

[0001] This invention relates to the field of river dredging technology, specifically to an intelligent support structure for a floating river dredging device. Background Technology

[0002] Dredging is an earthwork project that uses dredgers or other machinery and manual labor to excavate underwater in order to widen and deepen waterways. The trench design stress diagram of dredging projects changes the geometric boundary of the river flow, causing changes in the internal structure of the water flow. The newly formed water flow structure can not only ensure that silt does not accumulate in the waterway, but also transport the silt that enters the trench to the lower deep channel, thus maintaining the stability of the waterway.

[0003] When cleaning silt from the bottom of a river during dredging projects, the silt is usually removed by a cutter suction dredger or an excavator. However, cutter suction dredgers are large and require oscillation to adjust their angle for thorough cleaning of the silt at the bottom. Existing small rivers are typically narrow, hardened concrete channels, requiring manual operation of the cutter suction dredger within the channel. This method is inflexible, has a limited cleaning range, and results in poor cleaning effectiveness. Furthermore, the sludge cannot be separated from wastewater and discharged in a timely manner, hindering continuous automatic cleaning. Therefore, this application proposes an intelligent support structure for a floating river dredging device that is adapted for automatic cleaning of small rivers and ensures effective cleaning, thus addressing this deficiency in the prior art. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an intelligent support structure for a floating river dredging device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent support structure for a floating river dredging device, comprising a floating vessel, which floats in a hardened river channel. The upper end of the hardened river channel has hardened slope protection on both sides, and track grooves are provided on both sides of the upper end of the hardened river channel. Telescopic rods are provided in the middle of the front and rear sides of the upper end of the floating vessel. The connection end of the telescopic rods with the floating vessel is an extension end. A connecting plate is provided at the upper end of the telescopic rods, and a roller seat is provided at the other end of the connecting plate. Rollers located in the track grooves rotate in the roller seat.

[0006] The upper end of the floating vessel is equipped with a support frame, and the outer side of the support frame is equipped with a telescopic pipe. The telescopic pipe is composed of several hollow cylinders with diameters decreasing from top to bottom. The hollow cylinders slide and seal with each other. The top hollow cylinder is connected and fixed to the support frame. The lower end of the bottom hollow cylinder is connected to a submersible sludge pump. The outer side of the submersible sludge pump is equipped with a hollow seat in the shape of an isosceles trapezoid. The left and right sides of the hollow seat are sloping surfaces, and perforations are evenly distributed on the sloping surfaces. The left and right sides of the upper end of the hollow seat are equipped with crushing components to break up and crush the deposited sludge and impurities.

[0007] The upper end of the floating vessel is provided with a sludge storage chamber. The upper end of the top hollow cylinder is connected to a sewage pipe. The other end of the sewage pipe is located above the sludge storage chamber. The bottom wall of the floating vessel is provided with a screw conveyor located inside the sludge storage chamber and vertically upward. The lower end of the screw conveyor is provided with a feed inlet. The upper end of the screw conveyor is provided with a hose. The other end of the hose is provided with a sludge discharge pipe connected to one of the connecting plates.

[0008] The connecting plate is equipped with a traction assembly for pulling the floating vessel up to the top;

[0009] The support frame is equipped with a servo motor, the output end of the servo motor is equipped with a rotating shaft, the outside of the rotating shaft is equipped with a winding disc, and a steel wire rope is wound and fixed around the outside of the winding disc. The steel wire rope is connected to the hollow seat.

[0010] The floating vessel is equipped with filter screens on both the front and rear side walls. The filter screens are inclined downwards and the lower end of the filter screens is connected to the bottom of the floating vessel. The filter screens are sealed to the floating vessel on all four sides.

[0011] Multiple drainage pipes are connected to the front and rear surfaces of the floating vessel, and the drainage pipes are located below the filter screen.

[0012] Furthermore, the upper end of the roller seat is provided with an electric push rod, the push rod of which extends into the roller seat, and the push rod is provided with a friction plate for contacting and locking the roller.

[0013] Furthermore, the floating vessel is provided with triangular dividing frames on both the left and right sides, with the support frame located inside the dividing frame on the left side.

[0014] Furthermore, the crushing assembly includes drive motors located on the left and right sides of the front side of the upper end of the hollow seat, and the output end of the drive motors is provided with a crushing roller located on the outer side of the slope surface.

[0015] Furthermore, the traction assembly includes a loading seat located on the upper end of the connecting plate. A second servo motor is located on the right side of the loading seat. The output end of the second servo motor is equipped with a winding reel that rotates with the inner wall of the loading seat. A second steel wire rope, which passes through the connecting plate and the telescopic rod and is connected to the pontoon, is wound and fixed on the outside of the winding reel.

[0016] Furthermore, the upper end of the connecting plate is provided with a guide wheel seat located outside the loading seat, and a pair of guide wheels symmetrically distributed vertically are rotated inside the guide wheel seat, with a steel wire rope passing through the guide wheels.

[0017] Furthermore, when the extension end of the telescopic rod is in a fully extended state, the telescopic pipe is in a fully extended state, and the hose is not fully taut; when the extension end of the telescopic rod is in a fully retracted state, the telescopic pipe is in a fully retracted state, and the hose is not fully taut.

[0018] Compared with the prior art, the present invention provides an intelligent support structure for a floating river dredging device, which has the following beneficial effects:

[0019] 1. The intelligent support structure of this floating river dredging device drives the telescopic rod, connecting plate and roller seat to move as a whole through the set floating boat. At the same time, when the roller seat moves, the rollers in the roller seat move linearly in the track groove on the hardened river channel, thereby realizing the linear movement of the floating boat in the hardened river channel and avoiding movement deviation.

[0020] As the floating vessel moves, it drives the support frame, telescopic pipes, submersible sludge pump, and hollow seat to move synchronously. This ensures that the telescopic rods and pipes adapt to the rise and fall of the water level, allowing the hollow seat to move linearly with the floating vessel in the river channel. The inclined surface of the hollow seat avoids obstruction by the sludge at the bottom, and the crushing component breaks up the sludge and impurities in front of it in advance. Working in conjunction with the submersible sludge pump, it perforates and isolates large particles of obstruction while the sludge enters through the perforations and is extracted by the submersible sludge pump. Utilizing the interconnection between the telescopic pipes and the sewage pipe, the sludge and muddy water are discharged into the sludge storage chamber for storage, thereby achieving regular automatic and comprehensive cleaning of the river sludge, unaffected by the water level.

[0021] 2. The intelligent support structure of this floating river dredging device uses a filter screen plate installed in the sludge storage chamber to isolate sludge. Wastewater is discharged through the filter holes of the filter screen plate and then discharged back into the river through the drainage pipe. In addition, the inclined surface of the filter screen plate ensures that the sludge accumulates in the middle of the floating vessel. The sludge enters the screw conveyor through the feed inlet, and the floating vessel is pulled to the top by the traction component to ensure the discharge height of the hose. The sludge entering is then transported by the screw conveyor to the sludge discharge pipe connected to the hose and discharged. This realizes the automatic cleaning and discharge of the sludge from the floating vessel to the outside of the river, improving the cleaning efficiency and avoiding the accumulation of sludge in the floating vessel that would prevent continuous cleaning work.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 6 A floating river dredging device intelligent support structure mainly consists of a floating boat 1, a track trough 3, a telescopic rod 4, a roller seat 6, a support frame 11, a telescopic pipe 20, a submersible sludge pump 35, a crushing component, a sludge storage chamber 21, a screw conveyor 25, a filter screen 23, and a traction component.

[0031] The floating vessel 1 is made of high-strength fiberglass material, which has good buoyancy and stability. The floating vessel 1 floats on the water surface in the hardened river channel 2. The upper end of the hardened river channel 2 has sloping hardened slopes on both sides. Track grooves 3 are opened on both sides of the top of the upper end of the hardened river channel 2. The track grooves 3 are U-shaped concrete molding grooves to ensure the stable movement of the rollers 7.

[0032] Floating vessel 1 is an existing technology device equipped with electric propulsion units, installed on the left and right sides of the hull. The propulsion units use high-efficiency brushless DC motors as the power source. These motors are characterized by their small size, high efficiency, and fast response speed, providing strong and stable power output. The propulsion blades are made of carbon fiber composite materials, which have the advantages of being lightweight, high-strength, and corrosion-resistant. They can maintain good operating performance at high speeds and generate significant thrust, ensuring the floating vessel has good navigation capabilities in waterways. Floating vessel 1 uses a hydraulic rudder to achieve steering. The hydraulic rudder is installed at the stern of the hull and drives the steering rudder to swing through a hydraulic system. The steering rudder has a large-area design, which can effectively change the hull's direction of travel and has good maneuverability. The hydraulic system consists of hydraulic pumps, cylinders, control valves, etc., enabling precise steering control and ensuring the floating vessel's flexibility and maneuverability in complex waterway environments. It is also equipped with a lithium battery pack for power storage.

[0033] Telescopic rods 4 are bolted to the middle of the front and rear sides of the upper surface of the floating vessel 1. The connection end of the telescopic rod 4 to the floating vessel 1 is the extension end. A connecting plate 5 is fixed to the upper end of the telescopic rod 4. The connecting plate 5 is made of high-strength aluminum alloy. A roller seat 6 is bolted to the other end of the connecting plate 5. Rollers 7 rotate circumferentially inside the roller seat 6. The rollers 7 are made of high-strength polyurethane material, which has good wear resistance and shock absorption. The rollers 7 roll in the track groove 3 to ensure that the floating vessel 1 moves in a straight line along the track groove 3. Under pressure, the rollers 7 do not separate from the track groove 3.

[0034] It should be added that: an electric push rod 8 is fixed to the upper surface of the roller seat 6 by bolts. The push rod of the electric push rod 8 extends into the roller seat 6, and a friction plate 9 is fixed at the push rod to lock the roller 7 in contact with friction. When the electric push rod 8 works, it pushes the friction plate 9 to move, squeezing and rubbing the roller 7, thereby locking the roller 7 stably in the track groove 3.

[0035] A support frame 11 is bolted to the left side of the upper surface of the floating vessel 1. The support frame 11 is made of high-strength aluminum alloy, which has good mechanical strength and corrosion resistance. A telescopic pipe 20 is provided on the outside of the support frame 11. The telescopic pipe 20 is composed of several hollow cylinders with decreasing diameters from top to bottom. The hollow cylinders slide and seal with each other and are not separated. The top hollow cylinder is connected and fixed to the middle of the left side of the support frame 11. The bottom hollow cylinder is connected to a submersible sludge pump 35 at its lower end and is connected to the sewage outlet of the submersible sludge pump 35. A sealing ring is fitted at the connection between the hollow cylinders to ensure the sealing of the expansion and contraction between the hollow cylinders and prevent leakage.

[0036] It should be added that: a servo motor 12 is fixed to the front surface of the support frame 11 by bolts. The output end of the servo motor 12 is provided with a rotating shaft 13 that is circumferentially connected to the inner wall of the support frame 11. A winding disc 14 is fixed to the outside of the rotating shaft 13 at the same center. A steel wire rope 15 is wound and fixed to the outside of the winding disc 14. The other end of the steel wire rope 15 is connected to the upper surface of the hollow seat 16, so that the steel wire rope 15 can be driven by the servo motor 12 to move the hollow seat 16, so as to move it over obstacles or lift it for easy maintenance.

[0037] The left and right sides of the floating vessel 1 are fixed with triangular dividing frames 10 by bolts. The support frame 11 is located inside the left dividing frame 10, ensuring that when the floating vessel 1 is sailing in a straight line, the triangular inclined surface of the dividing frame 10 peels away water plants and floating objects on the river surface, thus preventing the floating vessel 1 from being obstructed.

[0038] The submersible sludge pump 35 is a high-efficiency, non-clogging submersible sludge pump. An isosceles trapezoidal hollow seat 16 is externally fixed with bolts. The left and right sides of the hollow seat 16 are sloping surfaces, facilitating its linear movement with the floating vessel 1 and preventing obstruction. Perforations 17 are evenly distributed on the sloping surfaces, and the diameter of the perforations 17 can be adjusted according to actual needs to effectively isolate large particles. The upper left and right sides of the hollow seat 16 are equipped with crushing components for breaking down and crushing deposited sludge and impurities. The crushing components include a drive motor 18 and a crushing roller 19. The drive motor 18 is fixed with bolts to the left and right sides of the upper front side of the hollow seat 16. The drive motor 18 is a high-efficiency, waterproof motor, and its output end is connected to and fixed with the crushing roller 19. The crushing roller 19 is located on the outer side of the sloping surface of the hollow seat 16 and is made of high-strength alloy steel, possessing good wear resistance and cutting performance.

[0039] The upper surface of the floating vessel 1 is provided with a sludge storage chamber 21. The upper end of the top hollow cylinder is connected to a sewage pipe 22. The other end of the sewage pipe 22 is located above the sludge storage chamber 21, which facilitates the discharge of sludge and sewage into the sludge storage chamber 21. The bottom wall of the floating vessel 1 is fixed with a screw conveyor 25 located in the sludge storage chamber 21 and vertically upward. The screw conveyor 25 adopts a shaftless screw design, which has good anti-winding and sealing performance. The lower end of the screw conveyor 25 is provided with a feed port 26, and the upper discharge port is connected to a hose 27. The hose 27 is made of high-pressure resistant rubber material, and the other end is connected to a sludge discharge pipe 28. The sludge discharge pipe 28 is made of high-strength plastic material and is connected and fixed to the upper surface of the front connecting plate 5.

[0040] The front and rear side walls of the inner cavity of the floating vessel 1 are fixed with filter screen plates 23 of the same length as the sludge storage chamber 21. The filter screen plates 23 are made of stainless steel, which has good filtration performance and corrosion resistance. The filter screen plates 23 are provided with filter holes, and the hole diameter can be adjusted according to the actual situation. The filter screen plates 23 are inclined downwards, and the inclination angle of the filter screen plates 23 can be adjusted according to actual needs to ensure that the sludge accumulates in the middle of the floating vessel 1. The lower surface of the filter screen plates 23 is connected and fixed to the bottom of the floating vessel 1. The lower ends of the two filter screen plates 23 are respectively located on the front and rear sides of the screw conveyor 25, ensuring that the middle is located at the lowest depression, which facilitates the sludge deposition into the screw conveyor 25. The filter screen plates 23 are sealed to the floating vessel 1 on all four sides to prevent sludge from being discharged below the filter screen plates 23. The front and rear surfaces of the floating vessel 1 are connected to multiple evenly distributed drainage pipes 24. The drainage pipes 24 are made of high-strength plastic and are located below the filter screen plates 23 to discharge the filtered sewage back into the river.

[0041] The connecting plate 5 is equipped with a traction assembly for moving the pontoon 1 to the top. The traction assembly includes a loading seat 29, a second servo motor 30, a winding reel 31, and a second steel wire rope 34, all bolted to the upper surface of the connecting plate 5. The loading seat 29 is made of high-strength steel. The second servo motor 30 is bolted to the right side surface. The second servo motor 30 is a high-precision servo motor with good control accuracy and torque output. The output end of the second servo motor 30 is fixed to the winding reel 31 via a coupling. The winding reel 31 rotates circumferentially with the inner wall of the loading seat 29. A steel wire rope 34 is wound and fixed around the top of the load base 29. The steel wire rope 34 passes through the connecting plate 5 and the telescopic rod 4. The steel wire rope 34 is made of high-strength galvanized steel wire, which has good tensile strength and corrosion resistance. The upper surface of the connecting plate 5 is fixed with a guide wheel seat 32 by bolts. The guide wheel seat 32 is located outside the load base 29. A pair of symmetrically distributed guide wheels 33 rotate inside the guide wheel seat 32. The guide wheels 33 are made of high-strength polyurethane material, which has good wear resistance and shock absorption. The steel wire rope 34 passes between the guide wheels 33 to ensure the stable transmission of the steel wire rope 34.

[0042] It should be added that: when the extension end of the telescopic rod 4 is in the fully extended state, the telescopic pipe 20 is in the fully extended state, and the hose 27 is not fully taut. When the extension end of the telescopic rod 4 is in the fully retracted state, the telescopic pipe 20 is in the fully retracted state, and the hose 27 is not fully taut. This ensures the telescopic coordination between the telescopic rod 4 and the telescopic pipe 20, while preventing the hose 27 from taut and falling off during extension and retraction.

[0043] The working principle of the equipment is that, during use, the connection between the telescopic rod 4, the connecting plate 5, the roller seat 6 and the floating boat 1 is achieved. The rollers 7 on the roller seat 6 roll in a directional manner in the track groove 3 on the hardened slope on both sides of the hardened river channel 2, so that the floating boat 1 can be driven to move in a straight line along the middle of the water surface of the hardened river channel 2, avoiding the deviation of the course caused by the water flow and wind force when the floating boat 1 is automatically sailing.

[0044] As the floating vessel 1 travels in a straight line along the hardened river channel 2, it drives the support frame 11, telescopic pipe 20, submersible sludge pump 35 and hollow seat 16 to move synchronously. The extension and contraction of the telescopic rod 4 and the telescopic pipe 20 enable adaptive extension and contraction support as the river surface rises and falls in the hardened river channel 2, ensuring that the hollow seat 16 moves in a straight line with the floating vessel 1 in the river channel.

[0045] When the hollow seat 16 moves, the inclined surface of the hollow seat 16 is designed to avoid being blocked by the sludge at the bottom, which would affect the movement of the hollow seat 16. In addition, when the hollow seat 16 moves, the drive motor 18 works to drive the crushing roller 19 to rotate, so as to crush the sludge and impurities in front in advance and avoid the movement of the hollow seat 16 being obstructed.

[0046] As the hollow seat 16 moves, the submersible sludge pump 35 operates. While the perforation 17 isolates large particles of obstacles, sludge enters through the perforation 17 and is extracted by the submersible sludge pump 35. By utilizing the interconnection between the telescopic pipe 20 and the sewage pipe 22, the sludge and muddy water are discharged into the sludge storage chamber 21 for storage.

[0047] The sludge stored in the sludge storage chamber 21 is isolated by the filter screen 23. Wastewater is discharged through the filter holes of the filter screen 23 and discharged back into the river through the drain pipe 24. In addition, the inclined surface of the filter screen 23 ensures that the sludge accumulates in the middle of the floating vessel 1. The sludge enters the screw conveyor 25 through the feed port 26. When it is necessary to clean the sludge stored in the sludge storage chamber 21, the electric push rod 8 is used to push the friction plate 9 to move, squeezing and rubbing the roller 7, thereby locking the roller 7 stably in the track groove 3.

[0048] After the lock is stabilized, the servo motor 30 drives the winding reel 31 to rotate and wind up the steel wire rope 34. The guide wheel 33 simultaneously guides and transmits the steel wire rope 34. After the rope is stacked on the water surface, the steel wire rope 34 pulls the floating boat 1 upward, ensuring that the hose 27 on the screw conveyor 25 and the sludge discharge pipe 28 form a downward angle to facilitate the discharge of sludge. The inclined slope of the outer filter plate 23 ensures that the sludge accumulates in the middle of the floating boat 1. The sludge enters the screw conveyor 25 through the feed port 26 and is then transported by the screw conveyor 25 to the sludge discharge pipe 28 connected to the hose 27 for discharge. This achieves automatic cleaning and discharge of the cleaned sludge from the floating boat 1 to the outside of the river, improving the cleaning efficiency and preventing the sludge from accumulating in the floating boat 1 and becoming unprocessed, which would prevent the continuous cleaning work from being interrupted.

[0049] In addition, when the hollow seat 16 is blocked by an obstacle and cannot be moved, or when maintenance is required, the servo motor 12 drives the winding disc 14 on the rotating shaft 13 to rotate, thereby winding the steel wire rope 15, pulling the hollow seat 16 up to move around the obstacle and then down, or pulling the hollow seat 16 up to the top for maintenance. The telescopic pipe 20 simultaneously provides telescopic support for the hollow seat 16, ensuring the cleaning effect and the convenience of maintenance.

[0050] In summary, this method enables automated and comprehensive dredging of small waterways via fixed routes, ensuring both efficiency and effectiveness.

[0051] Technical advantages and efficient dredging: The linear movement of the floating hull 1 and the extraction action of the submersible sludge pump 35 enable comprehensive cleaning of river sludge. The extension and retraction functions of the telescopic rod 4 and the telescopic pipe 20 ensure that the equipment adapts to changes in water level and improves dredging efficiency.

[0052] Intelligent control: The cooperation of servo motor 230 and traction components enables automatic traction and positioning of the floating vessel 1. The intelligent control system ensures stable operation of the equipment in complex environments.

[0053] Sludge separation and treatment: The design of filter screen 23 and drain pipe 24 realizes the separation of sludge and sewage, reduces the volume of sludge, and improves treatment efficiency. The vertical conveying function of screw conveyor 25 ensures timely discharge of sludge and avoids accumulation.

[0054] Highly adaptable: The equipment is suitable for small, hardened river channels and is highly flexible. The design of the telescopic boom 4 and telescopic pipe 20 ensures that the equipment can operate stably under different water levels.

[0055] The system control uses a PLC (Programmable Logic Controller) or a microcontroller as the core controller, which has high reliability and powerful control functions.

[0056] In summary, the intelligent support structure of this floating river dredging device significantly improves the efficiency and effectiveness of river dredging through automated sludge extraction, crushing, conveying, and discharge functions. With reasonable structural design, material selection, and intelligent expansion, this equipment has broad application prospects in the field of river dredging and can effectively solve the problem of dredging small rivers.
