Technical Field

[0001] The utility model relates to the technical field of river cleaning, in particular to a river cleaning device. Background Art

[0002] There is often a problem of floating garbage in rivers. A large amount of floating garbage gathers, and the garbage in the river floats on the river surface for a long time. When it gathers together, it pollutes the river environment, pollutes the water quality, and affects people's living water supply.

[0003] After searching, Chinese patent announcement No. CN219840047U discloses a garbage salvage device for river cleaning, including a support frame, a symmetrically distributed guide plate is provided at the left end of the support frame, the guide plate is hinged to the upper surface of the left end of the support frame, a connecting seat is provided above the right end of the support frame, a salvage frame is provided in the middle of the support frame, a limiting structure is provided on the right side of the salvage frame, a hinged seat is provided on the upper surface of the protruding end of the right end of the support frame, a sliding waist hole is provided at the right end of the support frame, a hinged boss is provided on the outer surface of the left end of the support frame, an arc-shaped transition rod is provided at the left end of the support frame, and an obliquely installed intercepting rod is provided below the arc-shaped transition rod. The guide plate cooperates with the support frame to perform salvage work simultaneously when the cleaning boat moves. The guide plate can collect and process the garbage in front of the boat in a centralized manner, thereby improving the salvage efficiency. The overall working state of the garbage salvage device can be adjusted through the limiting structure to adapt to different river working environments.

[0004] However, in the above technical solution, the aquatic plants are salvaged and cleaned only by the entanglement between the intercepting rod and the guide rod and the aquatic plants. However, when a large amount of aquatic plants are entangled on the intercepting rod and the guide rod, it will affect the collection of other garbage, and the dense aquatic plants will increase the resistance of the ship and thus affect the normal driving of the ship.

[0022] The cleaning assembly includes a guide plate 4, a connecting frame 5, a filter box 6 and a cutting assembly. The guide plate 4 is connected to the side wall of the fixed frame 1, and the guide plate 4 is tilted; the guide plate 4 is tilted so that the end of the guide plate 4 away from the fixed frame 1 can be extended into the water to contact the debris; the connecting frame 5 is detachably connected to the fixed frame 1; a plurality of equally spaced dovetail blocks 13 are connected to the connecting frame 5, and the dovetail blocks 13 are slidably connected to the dovetail grooves 14 provided on the fixed frame 1; a symmetrically arranged handle is connected to the upper end surface of the connecting frame 5; the filter box 6 is connected to the lower end surface of the connecting frame 5;

[0023] In an optional embodiment, an opening is provided on the side wall of the filter box 6, and a conical guide plate 9 is connected to the opening; the guide plate 9 is trumpet-shaped, and its diameter gradually decreases from the opening of the filter box 6 to the inside, and no mesh is provided on the surface of the guide plate 9 to prevent waterweed branches from getting stuck in the mesh and causing blockage;

[0024] The cutting assembly is connected to the fixing frame 1; when the cutting assembly is in use, the cutting assembly contacts the waterweed debris entangled on the surface of the cutting assembly, and the entanglement of the waterweed increases the resistance on the professional and filter screen box 6, and the resistance pushes the waterweed to slide on the cutting assembly so that the cutting end of the cutting assembly contacts the waterweed to cut it off;

[0026] Embodiment 2

[0027] like Figure 1-Figure 2 As shown, a river cleaning device proposed by the utility model, compared with the first embodiment, the detailed structure of the extension component is recorded in this embodiment, the extension component includes a fixed frame 10, a secondary filter plate 11 and a telescopic device 12, two fixed frames 10 are symmetrically arranged, and the fixed frames 10 are connected to the fixed frame 1; the fixed frame 10 is in an inverted L shape, that is, a horizontal plate is provided on the top; the secondary filter plate 11 is rotatably connected to the fixed frame 10; one end of the secondary filter plate 11 is connected to a rotating shaft, and the rotating shaft is rotatably connected to the top horizontal plate of the fixed frame 10 through a bearing; one end of the telescopic device 12 is hinged and rotatably connected to the fixed frame 1; the telescopic device 12 is selected from but not limited to a hydraulic cylinder; the output end of the telescopic device 12 is hinged and rotatably connected to the secondary filter plate 11;

[0029] In summary, when the utility model is used, the staff connects the connecting rod 2 and the fixed frame 1 to the front end of the boat through bolts, and the boat starts to move forward on the water surface. At this time, as the boat moves forward, the plastic bottles or other garbage floating on the water surface will be guided by the guide rod 7 and the guide plate 4 to gradually rise and fall into the filter box 6 in the fixed frame 1. When it is necessary to expand the cleaning range, the telescopic device 12 is started, and the telescopic end of the telescopic device 12 pushes the auxiliary filter plate 11 to rotate. The auxiliary filter plates 11 on both sides form an eight-shaped or trumpet shape to increase the contact range with the water surface and guide the garbage to make it close to the guide rod 7. As the boat moves forward, the garbage will be guided by the guide rod 7. The waterweeds floating on the water surface contact the guide rod 7 and are entangled on its surface. As the boat moves, the waterweeds will move to the bottom of the guide rod 7, that is, the guide plate 4. At this time, the waterweeds will contact the cutting blade 8, and the cutting blade 8 will cut the waterweeds. The waterweeds on the upper end surface of the guide rod 7 will enter the filter screen box 6 as it moves, and the waterweeds on the lower end surface of the guide rod 7 will sink into the water after being cut off. As the filter screen box 6 moves, it will enter the filter screen box 6 from the conical guide plate 9 at the opening of the filter screen box 6. The arc plates 15 on both sides of the filter screen box 6 can increase the contact with the waterweeds in the water to prevent the waterweeds from escaping away from the filter screen box 6 after being cut off.
