Description

Technical Field

[0001] This invention relates to the field of river waste treatment technology, and in particular to a treatment device for river waste. Background Technology

[0002] River waste treatment devices are automated cleaning equipment designed for aquatic environments such as rivers, lakes, and landscape water bodies. They are primarily used to salvage, collect, and transport floating garbage, fallen leaves, plastic bags, foam, aquatic plants, and other waste from the water surface. These devices are crucial for maintaining the aquatic ecosystem, ensuring water flow, and improving water quality. Typically, these devices feature water surface adaptability, garbage salvage, aquatic plant cutting, and waste collection functions. They can replace manual labor to achieve large-scale, efficient, and continuous river cleaning operations and are widely used in urban rivers, wetland parks, and reservoir areas, playing a significant role in improving water quality and reducing manual cleaning costs.

[0003] Existing river dredging technologies have some shortcomings in terms of equipment and operation methods, making it difficult to meet the needs of efficient dredging: First, river debris is scattered and covers a wide area, making manual removal extremely inefficient, labor-intensive, and posing a safety hazard of people falling into the water. Furthermore, the low level of mechanization prevents large-scale, continuous operations. Second, river debris is often entangled with aquatic plants and algae. Ordinary removal equipment can only collect floating debris and cannot effectively cut tangled aquatic plants, resulting in a messy and difficult-to-remove situation that easily causes equipment jams and blockages, significantly increasing the difficulty of cleanup. In addition, most equipment lacks adaptive adjustment capabilities, making it unable to adapt to different water levels and river widths. Discontinuous debris transport and collection can easily cause secondary pollution and result in poor cleanup outcomes. Summary of the Invention

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Reference Figures 1-6 Example 1: A device for treating river waste includes a frame 1, with symmetrically distributed fixed plates 2 welded to one side of the outer wall of the frame 1, and a movable plate 3 rotatably connected to one end of the outer wall of the fixed plate 2. An electric push rod 4 is hinged between the movable plate 3 and the fixed plate 2, and a mesh conveyor 5 is installed on the inner wall of the frame 1 and the fixed plate 2.

[0019] Through the above scheme, the frame 1 provides the main support and installation foundation for the device, the fixed plate 2 is used to connect the movable plate 3 and the frame 1 to form a stable hinge structure, the movable plate 3 can rotate around the fixed plate 2 to adjust the angle of retrieval into the water, the electric push rod 4 adopts the model DTZ500 electric push rod 4, the working mode is reciprocating telescopic drive, pushes the movable plate 3 to rise and tilt, adapting to different water levels and retrieval needs, the mesh chain conveyor 5 adopts the model WLS300 stainless steel mesh chain conveyor 5, the working mode is continuous circulation conveying, transporting the retrieval of garbage and aquatic plants to the sludge collection frame 18, realizing continuous retrieval and solving the problem of low efficiency of manual cleaning.

[0020] In this embodiment, the retrieval angle is adaptively adjusted by the cooperation of the frame 1, the fixed plate 2, the movable plate 3, the electric push rod 4 and the mesh conveyor 5. The floating wheel 23 adapts to the water level, the electric push rod 4 adjusts the tilt angle of the movable plate 3, and the mesh conveyor 5 continuously retrieves and transports floating garbage without manual intervention. The retrieval range is wide and the continuity is strong, reducing the intensity of manual labor and safety risks.

[0021] In embodiment 2, a first gear 6 and a second gear 7 that mesh with each other are provided on the outer wall of one side of both movable plates 3, and a secondary traction roller 8 is installed through the inner wall of the first gear 6 and the second gear 7. A servo motor 9 is fixedly connected to the top outer wall of one of the secondary traction rollers 8 through a coupling. A main traction roller 10 is rotatably connected to one side of the outer wall of the movable plate 3, and a pulley pair 11 is installed between the main traction roller 10 and one of the secondary traction rollers 8.

[0022] Through the above scheme, the servo motor 9 adopts an ACM-600W AC servo motor 9, which operates in a continuous rotation drive mode to provide stable power. The first gear 6 and the second gear 7 mesh with each other to realize the synchronous counter-rotation of the two auxiliary traction rollers 8, which gathers the floating garbage on the water surface to the center and prevents the garbage from escaping. The main traction roller 10 rotates synchronously with the auxiliary traction roller 8 through the pulley pair 11 to provide power to the aquatic weed cutting mechanism 12. The combination of gear transmission and belt transmission ensures stable power transmission, guarantees synchronous operation of traction and cutting, and improves the garbage gathering effect.

[0023] In this embodiment, through the transmission cooperation of the first gear 6, the second gear 7, the auxiliary traction roller 8, the main traction roller 10 and the pulley pair 11, the single-power double roller synchronous traction is realized, which gathers the water surface garbage and aquatic plants towards the retrieval port, prevents the garbage from scattering, improves the retrieval success rate, and at the same time provides stable power to the main traction roller 10 to ensure the continuous operation of the aquatic plant cutting mechanism 12.

[0024] In embodiment 3, a weed cutting mechanism 12 is provided on the top outer wall of the main traction roller 10. The weed cutting mechanism 12 includes a rotating disk 121, a traction block 122, a connecting rod 123, a reciprocating moving column 124, an L-shaped guide plate 125, an L-shaped connecting plate 126, and a sawing plate 127. The rotating disk 121 is fixedly connected to the top outer wall of the main traction roller 10. The traction block 122 is welded to the top outer wall of the rotating disk 121. The connecting rod 123 is rotatably connected to the outer wall of the traction block 122. The reciprocating moving column 124 is rotatably connected to the outer wall of one end of the connecting rod 123. The L-shaped guide plate 125 is welded to the outer wall of the other side of the movable plate 3, and the reciprocating moving column 124 is disposed through the inner wall of the L-shaped guide plate 125. The L-shaped connecting plate 126 is installed on the outer walls of both ends of the reciprocating moving column 124. The sawing plate 127 is welded to the top outer wall of the L-shaped connecting plate 126.

[0025] With the above scheme, the rotary disk 121 rotates with the main traction roller 10. The rotational motion is converted into the linear reciprocating motion of the reciprocating column 124 through the traction block 122 and the connecting rod 123. The L-shaped guide plate 125 provides guidance for the reciprocating column 124 to ensure smooth movement. The L-shaped connecting plate 126 connects the reciprocating column 124 and the saw blade 127, driving the saw blade 127 to cut back and forth at high speed. The saw blade 127 adopts a stainless steel saw tooth blade to quickly cut the water plants wrapped around the garbage, so that the garbage and water plants are separated, solving the problem of mixed entanglement and difficulty in cleaning, and preventing equipment blockage.

[0026] In this embodiment, the rotating disk 121, connecting rod 123, reciprocating moving column 124 and saw blade 127 of the aquatic plant cutting mechanism 12 realize high-speed reciprocating cutting of aquatic plants, quickly separate and cut off the garbage and the tangled aquatic plants, avoid the aquatic plants from tangling and clogging the equipment, and enable the garbage to be smoothly retrieved and transported, fundamentally solving the problem of garbage and aquatic plants being difficult to clean.

[0027] A support plate 13 is welded to one side of the outer wall of the movable plate 3, and two auxiliary traction rollers 8 are rotatably connected to the inner wall of the support plate 13. An angle plate 14 is welded to the top outer wall of the support plate 13, and the servo motor 9 is fixedly connected to the top outer wall of the angle plate 14 by screws.

[0028] Through the above scheme, the support plate 13 provides rotational support for the auxiliary traction roller 8 to ensure smooth rotation, and the corner plate 14 fixes the servo motor 9 to enhance installation stability, prevent motor vibration during operation, ensure stable power output, and extend the service life of transmission components.

[0029] A side entrance 15 is provided on one side of the outer wall of the movable plate 3, and limit plates 16 are welded to the inner walls on both sides of the side entrance 15.

[0030] With the above solution, the side inlet 15 provides a channel for garbage and aquatic plants to enter the device, and the limiting plate 16 prevents garbage from drifting to both sides, guides the garbage to the central retrieval area, improves retrieval efficiency, and prevents garbage from being missed from the side.

[0031] Scrapers 17 are welded to the inner wall of the frame 1, and the scrapers 17 are closely attached to the upper bottom of the mesh conveyor 5.

[0032] Through the above solution, the scraper 17 closely adheres to the surface of the mesh conveyor 5, scraping off the weeds, sludge, and debris adhering to the mesh chain, preventing the mesh from becoming clogged, ensuring the continuous and smooth operation of the mesh conveyor 5, and avoiding secondary pollution caused by sludge accumulation.

[0033] A sludge collection frame 18 is placed on the inner wall of the bottom of the frame 1, and an installation door 19 that matches the size of the sludge collection frame 18 is hinged to the outer wall of the other side of the frame 1.

[0034] Through the above solution, the sludge collection frame 18 centrally collects the salvaged garbage and aquatic plants, facilitating unified transportation and treatment. The hinged design of the installation door 19 makes it easy to quickly remove the sludge collection frame 18 to dump the garbage, making the operation convenient and improving the efficiency of garbage cleaning and transportation.

[0035] A top plate 20 is welded to the top outer wall of the frame 1, and a solar photovoltaic panel 21 is installed on the top outer wall of the top plate 20.

[0036] Through the above scheme, the top plate 20 provides an installation platform for the solar photovoltaic panel 21. The solar photovoltaic panel 21 adopts a monocrystalline silicon 100W photovoltaic panel and works by photoelectric conversion to power supply, converting solar energy into electrical energy, providing green energy for the device, reducing energy consumption, and is suitable for long-term operation in the field river.

[0037] The outer walls of both sides of the frame 1 are equipped with symmetrically distributed floating wheels 23.

[0038] Through the above scheme, the floating wheel 23 adopts an inflatable rubber floating wheel, and the working mode is buoyancy support self-adaptation, so that the device floats on the water surface and automatically rises and falls with the water level, ensuring that the salvage port is always at the optimal water entry height, thereby improving the adaptability and stability of the device.

[0039] A controller 22 is installed on the outer wall of the top plate 20, and the controller 22 is electrically connected to the electric push rod 4, the mesh conveyor 5, the servo motor 9, and the floating wheel 23 via signal lines.

[0040] Through the above scheme, the controller 22 adopts a PLC controller 22 of model S7-1200, which operates in the mode of programmable logic control. It centrally controls the tilt angle of the electric push rod 4, the speed of the mesh conveyor 5, the start and stop of the servo motor 9, and the travel direction of the floating wheel 23, so as to realize automated and intelligent river cleaning and easy operation.

[0041] Working principle: The device floats on the river surface via a floating wheel 23, is powered by solar photovoltaic panels 21, and is activated by the controller 22. The electric push rod 4 extends and retracts to adjust the tilt angle of the movable plate 3, allowing the retrieval port to be immersed in a suitable water level. Servo motor 9 drives the first gear 6 and the second gear 7 to rotate in opposite directions, which in turn drives the auxiliary traction roller 8 to rotate, gathering the water surface debris and aquatic plants towards the side inlet 15; at the same time, the belt pulley pair 11 drives the main traction roller 10 to rotate, driving the aquatic plant cutting mechanism 12 to run. The rotating disk 121 drives the reciprocating moving column 124 and the saw blade 127 to reciprocate at high speed through the connecting rod 123, cutting the tangled aquatic plants. The debris and the cut aquatic plants enter the mesh conveyor 5 through the side inlet 15 and are continuously transported to the inside of the car frame 1. The scraper 17 scrapes off the debris adhering to the mesh chain, and the debris finally falls into the collection frame 18 for collection. After the sludge collection frame 18 is full, the installation door 19 is opened to remove and clean it. The device can be moved continuously and can be operated without manual dredging. It automatically completes the integrated treatment of aquatic weed cutting, garbage retrieval, transportation and collection, which effectively solves the problems of difficult cleaning of mixed garbage and aquatic weeds in river channels and the difficulty of manual cleaning.
