Two layers of filter plates are arranged in the garbage bin 9 from top to bottom, and the filter holes of the first layer of filter plates 18 are larger than the filter holes of the second layer of filter plates; a turnover drive mechanism 10 connected to the garbage bin 9 is provided in the garbage disposal bin, and the top of the conveyor belt 6 corresponds to the upper and lower positions of the top of the garbage bin 9. A spray assembly is also provided in the processing bin, and the nozzle 7 of the spray assembly is located directly above the trash bin 9; the water circulation system includes a submersible pump 26, a booster sewage pump 27, a three-way pressure regulating valve 25, an inlet filter valve 171, an outlet filter valve 172 and a regulating valve 28. The submersible pump 26 is provided in the water inlet bin, and the outlet of the submersible pump 26 is connected to the three-way pressure regulating valve 25. The first outlet of the three-way pressure regulating valve 25 is connected to the spray assembly through a first horizontal pipeline 32, and the outlet filter valve 172 is installed on the first horizontal pipeline 32. The second outlet of the three-way pressure regulating valve 25 is connected to the outside world through a vertical pipeline 31. The regulating valve 28 is provided on the sewage outlet at the bottom of the trash bin 9. The regulating valve The outlet of the booster sewage pump 28 is connected to the booster sewage pump 27, and the outlet of the booster sewage pump 27 is connected to the water inlet 29 of the submersible pump 26 through the second horizontal pipeline 30. The water inlet filter valve 171 is installed on the second horizontal pipeline 30; the trackable solar panel 1 is set on the top of the cabin body, and the battery 24 of the cabin body is powered by the trackable solar panel 1; the float assembly 2 includes two floats fixed to the left and right sides of the cabin body respectively; the thruster assembly 3 is set at the bottom of the cabin body; the camera assembly includes an above-water camera 11 and an underwater camera 4, the above-water camera 11 is installed on the top of the cabin body, and the underwater camera 4 is installed on the bottom of the cabin body;The operation panel 5 is mounted on the cabin body. The cylinder 22, the tilting drive motor 15, the conveyor belt 6, the scissor lift 20, the tilting drive mechanism 10, the spray assembly, the submersible pump 26, the booster sewage pump 27, the battery 24, the thruster assembly 3, the camera assembly, and the operation panel 5 are all electrically connected to the control cabinet 14. The control cabinet 14 receives commands input from the operation panel 5 to implement automated control.

[0024] The cabin body is divided into three areas, of which the water inlet compartment forms a closed space through the water inlet baffle 23, the water outlet baffle 21, and the left and right side walls of the cabin body. The water inlet baffle 23 can move up and down along the guide rail driven by the cylinder 22. When the water inlet baffle 23 moves downward, the garbage inlet 12 gradually becomes visible above the water inlet baffle 23. When the water outlet baffle 21 is flipped from a vertical state to a horizontal state driven by the flip drive motor 15, the garbage outlet 33 gradually becomes visible. The conveyor belt 6 can move the garbage at the garbage outlet 33 upward to the top of the garbage bin 9. The conveyor belt 6 continues to rotate, and the garbage will fall into the garbage bin 9. The first layer of filter plates 18 of the garbage bin 9 can filter larger garbage such as water bottles. Phytoplankton such as water plants pass through the first layer of filter plates 18 under the action of water flow and stay on the second filter plates 19. The remaining sewage flows into the bottom layer of the garbage bin 9. Sewage passes through regulating valve 28 and, driven by booster sewage pump 27, is first filtered through inlet filter valve 171 before flowing into water inlet 29 of submersible pump 26. Submersible pump 26 operates, drawing water from the inlet tank. Under the action of three-way pressure regulating valve 25, the water flows to outlet filter valve 172. The water then flows through the spray assembly, flushing the garbage in trash bin 9 and completing the complete cycle. Furthermore, as submersible pump 26 draws water from the inlet tank, external garbage, under the pressure differential of the water flow, enters the inlet tank through garbage inlet 12. Cylinder 22 activates, causing inlet baffle 23 to move upward along the guide rails, sealing the inlet tank. Outlet baffle 21 flips, opening garbage outlet 33. After passing through garbage outlet 33, garbage is transported to the trash bin by conveyor belt 6.

[0025] In addition to the above embodiment, in a preferred embodiment, the waste disposal bin is further provided with a squeezing mechanism. The squeezing mechanism comprises a liftable and rotatable electric cylinder 8 and a squeezing plate 16. The squeezing plate 16 is connected to the movable end of the electric cylinder 8 via a connecting rod. The squeezing plate 16 is adapted to fit within the waste bin 9 and, driven by the electric cylinder 8, is used to squeeze the waste within the waste bin 9. The electric cylinder 8 is electrically connected to the control cabinet 14 for control by the control cabinet 14. Under the control of the control cabinet 14, when not in use, the squeezing plate 16, driven by the electric cylinder 8, rotates to the side of the waste bin 9, thereby preventing it from interfering with waste disposal. After the waste has been filtered, the control cabinet 14 controls the squeezing plate 16 to rotate until it is aligned with the waste bin 9. The electric cylinder 8 then controls the squeezing plate 16 to press into the waste bin 9, compressing the waste on the first filter layer within the waste bin 9 and saving space. The waste bin 9 can then be flipped over by controlling the tilting drive mechanism 10 and the scissor lift 20, allowing the waste to be dumped out. The first filter layer can then be removed and the waste on the second filter layer can be processed. After cleaning, the two filter layers are installed back into the trash can 9, and then the trash can 9 is controlled to return to its original position and the next garbage cleaning cycle is carried out.

[0026] In a preferred embodiment, based on the above-described embodiment, the tilting drive mechanism 10 includes a telescopic cylinder and a vertical slide bar. The bottom of the vertical slide bar is connected to an articulated seat via an articulated lug. The articulated seat is fixedly connected to the bottom of the waste disposal bin. The vertical slide bar is equipped with a slider, which is fixedly connected to the outer wall of the waste bin 9. One end of the telescopic cylinder is hinged to the articulated seat via the articulated lug, and the other end is connected to the slider via an articulated structure. When the scissor lift 20 lifts the waste bin 9 upward, the vertical slide bar and the slider undergo relative displacement. The telescopic cylinder is then controlled to move, and in conjunction with the articulated structure, the waste bin 9 can be tilted.

[0027] The working principle of the water surface garbage cleaning and collection device based on the water circulation system described in the utility model is:

[0028] A staff member enters commands on the operating panel 5. Under the control of the control cabinet 14, the camera assembly uses the target detection YOLO algorithm to identify garbage. The underwater camera 4 identifies the garbage in the water and prevents the propeller assembly 3 from becoming entangled in waterweed. The propeller assembly 3 uses differential speed to control the cabin body to steer, ultimately automatically cruising to the garbage location. The outflow baffle 21 swings downward under the action of the flip drive motor 15, sealing the cabin. The cylinder 22 operates to move the inflow baffle 23 downward along the guide rails, opening the garbage inlet 12 and allowing water to flow into the cabin. The submersible pump 26 operates to extract water from the cabin. The three-way pressure regulating valve 25 operates to direct the water to the outside and the outflow filter valve 172. Under the pressure difference of the water flow, the external garbage enters the water inlet through the garbage inlet 12. The cylinder 22 operates to move the inflow baffle 23 upward along the guide rails, sealing the cabin. The outlet baffle 21 flips to open the garbage outlet 33, through which the garbage passes. Driven by the reduction motor 13, the conveyor belt 6 moves the garbage upward into the trash can. Water flowing through the outlet filter valve 172, under the action of the spray nozzle 7 of the spray assembly, cleans and rinses the garbage in the trash bin 9. The first filter plate 18 of the trash bin 9 filters larger garbage, such as water bottles. Phytoplankton, such as aquatic plants, pass through the first filter plate 18 and settle on the second filter plate 19. The remaining wastewater flows into the bottom layer of the trash bin 9. The wastewater passes through the regulating valve 28 and, driven by the booster sewage pump 27, is first filtered through the inlet filter valve 171 before flowing into the water inlet 29 of the submersible pump 26. The submersible pump 26 operates, drawing water from the inlet tank. Under the action of the three-way pressure regulating valve 25, the water flows to the outlet filter valve 172. The water is then discharged through the spray assembly, flushing the garbage in the trash bin 9. This completes the recycling cycle and the clean utilization of water resources. After the garbage has been filtered, the control cabinet 14 controls the squeeze plate 16 to rotate until it aligns with the trash bin 9. Then, the electric cylinder 8 is controlled to press the squeeze plate 16 into the trash bin 9, compressing the garbage on the first filter layer in the trash bin 9 and saving space. The trash bin 9 is then flipped over by controlling the tilt drive mechanism 10 and the scissor lift 20, emptying the garbage. The staff then removes the first filter layer and processes the garbage on the second filter layer. Once cleaned, both filter layers are returned to the trash bin 9, which is then returned to its original position, beginning the next garbage cleaning cycle.

[0029] The trackable solar panel 1 charges the battery 24 to supply power to the control cabinet 14 and other equipment, ensuring the normal operation of the machine. The float assembly 2 ensures that the cabin body is stable at a certain height relative to the water surface.
