[0002] In the river channel, due to the sufficient supply of water, a large amount of aquatic plants will be produced on both sides of the river channel and on the water surface under the action of long-term action. The effect of aquatic plants will affect the movement of small fishing boats and cleaning boats in the river channel, which requires a great consumption of manual labor and will cause the accumulation of dirt and garbage on the river channel surface. In order to maintain the environmental sanitation of the river channel and normal traffic, it is necessary to regularly clean the aquatic plants in the river channel through cleaning devices.

[0045] 1. The water plants and water are filtered through the filter plate, so that the water passes through the filter plate and is discharged back to the river from the outlet trough, while the water plants are blocked on the filter plate by the baffle. Under the action of the waterproof cylinder, the push plate pushes the water plants toward the baffle, and the water plants squeeze the baffle to move to reveal the feed port. The water plants are pushed and fall into the feed port and collected. This prevents the water plants from being overweight due to the water they carry, which affects the subsequent treatment of the water plants.

[0046] 2. The waterproof motor controls the rotation of the propeller by controlling the start and stop and the speed. The thrust generated by the propeller rotation will push the hull forward. The airbag makes the hull suspended on the water surface, so that the hull can travel smoothly on the water surface. In this way, the river cleaning device can efficiently move on the water surface and clean the river channel, while keeping the hull stably suspended, improving the cleaning efficiency and operation convenience;

[0047] 3. The power unit provides power to drive the rotating shaft to rotate, and the rotating shaft drives the transmission wheel to rotate, so that the feeding belt runs. The feeding belt picks up the water plants on the water surface and transports them forward, so that the water plants are transported to the lower hopper. The water plants slide from the lower hopper to the feed hopper, and the feed hopper transports the water plants to the filter plate, so that the water plants and debris in the river can be effectively collected, so as to keep the river unobstructed and clean;

[0048] 4. By starting the waterproof motor, the transmission shaft starts to rotate, thereby driving the crushing blades to rotate. During the rotation process, the crushing blades will crush the aquatic plants and debris entering the crushing barrel into small particles or fine fragments. The fine fragments can then be more easily processed, collected or discharged from the device, thereby more effectively cleaning the river and reducing pollution and impact on the water environment.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0058] Embodiment 1:

[0059] like Figure 1-Figure 4 As shown, this embodiment provides a river cleaning device, comprising:

[0060] Hull 1;

[0061] A material storage frame 2 is arranged at the front side of the hull 1;

[0062] The material dividing component 3 is arranged in the material storage frame 2 and is used for filtering the water plants and the water carried by the water plants;

[0066] The guide rod 33 is arranged at the front and rear ends of the left side of the material storage frame 2;

[0067] The baffle plate 34 is slidably disposed between the two guide rods 33, the baffle plate 34 is located on the left side inside the material storage frame 2, and the baffle plate 34 is located on the left side of the filter plate 31;

[0068] The elastic member 35 is sleeved on the guide rod 33 and arranged between the baffle plate 34 and the material storage frame 2;

[0069] A feed inlet 36 is provided at the bottom of the left side of the material storage frame 2, and the feed inlet 36 is located on the left side of the baffle 34;

[0070] The waterproof cylinder 37 is arranged at the front and rear ends of the right side of the material storage frame 2;

[0071] The push plate 38 is disposed between the piston rods of the two waterproof cylinders 37. The push plate 38 is located on the right side of the material storage frame 2 and on the right side of the filter plate 31.

[0072] A filter chamber 39 is formed between the push plate 38 , the baffle plate 34 and the filter plate 31 , and the aquatic plants are pushed by the push plate 38 through the filter chamber 39 to the feed port 36 on the left side of the baffle plate 34 .

[0073] In the present technical solution, the device moves in the water through the hull 1 to cover different areas of the river. When the waterweed and water pass through the storage frame 2, the waterweed and water are located on the filter plate 31 of the filter chamber 39, so that the filter plate 31 filters the water, so that the water passes through the filter plate 31 and is discharged back into the river from the water outlet trough 32, while the waterweed is blocked on the filter plate 31 by the baffle 34. After the waterweed is filtered, people start the waterproof cylinder 37, and the piston rod of the waterproof cylinder 37 extends, driving the push plate 38 to move to the left, and the push plate 38 moves to the left along the filter plate 31, thereby pushing the waterweed on the filter plate 31 to the left, and the waterweed squeezes the baffle 34 during the movement to the left. , causing the baffle 34 to move to the left along the guide rod 33, and the elastic member 35 is compressed. When the aquatic plants squeeze the baffle 34 to move to the left to expose the feed port 36, the aquatic plants are pushed to fall into the feed port 36 and collected. Then the piston rod of the waterproof cylinder 37 retracts, driving the push plate 38 to move to the right and reset. The baffle 34 moves to the right and resets through the elastic member 35 without pressure. Then the above operation can be repeated to filter the aquatic plants to prevent the aquatic plants from being overweight due to the water they carry, which affects the subsequent treatment of the aquatic plants. The aquatic plants and water can be effectively separated and filtered, thereby cleaning the river channel and ensuring that the river channel is unobstructed.

A handle 5 is provided on the left side of the collecting frame 4.

[0079] In the present technical solution, after the aquatic plants are filtered, they are pushed into the feed port 36, and the aquatic plants fall into the collecting frame 4 from the feed port 36. The collecting frame 4 collects the aquatic plants. When the collected aquatic plants need to be processed, people pull the handle 5, and the handle 5 drives the collecting frame 4 to move to the left along the hull 1 until the collecting frame 4 is moved out of contact with the hull 1. People can then process the aquatic plants in the collecting frame 4. After the processing is completed, the collecting frame 4 is installed back to its original position. In this way, the aquatic plants can be collected, which is convenient for processing.
