The controller controls the action of the waterproof motor 43 according to the water level fed back by the liquid level sensor 47, so as to drive the outer barrel 31 to lift along with the water level, and ensure that the outer retainer ring 34 is always positioned 3cm below the water level.

When the water-proof motor 43 is used specifically, the outer barrel 31 moves downwards until the outer retainer ring 34 is positioned 3cm below the water surface, and the buoyancy tube floats upwards at the beginning because the buoyancy of the buoyancy tube is greater than the gravity until the buoyancy and the gravity of the buoyancy tube are equal, and the upper end of the buoyancy tube is about 15cm higher than the water surface; then the submersible pump 32 is electrified to work, the water in the outer barrel 31 is pumped and discharged to the external water area, when the water amount in the outer barrel 31 is reduced to a certain amount, the gravity of the buoyancy tube is larger than the buoyancy of the water supplied to the buoyancy tube again, and the buoyancy tube descends along with the water; when the buoyancy tube is lowered below the water surface until the stopper 28 abuts against the outer retainer ring 34, a fluid vortex centripetal suction force is generated due to a difference in liquid level between the water level in the outer tub 31 and the external water surface, thereby sucking the surrounding water and the floating garbage. After a large amount of water gushes into the outer barrel 31, the buoyancy of the buoyancy tube is larger than the gravity, so that the floating garbage can float upwards and is higher than the water surface, and the floating garbage can be collected in a reciprocating mode.

In the process of sucking surrounding water and floating garbage, external water flow flows into the valve body 11 from the inlet, flows out from the outlet 12 and flows into the garbage collection net 33, the garbage collection net 33 intercepts the garbage in the net, and the valve plate 14 can bend downwards under the combined action of the internal suction force and the external water flow so as not to influence the passing of the garbage and the water flow; when the buoyancy pipe floats upwards, the acting force of the internal suction force and the external water flow disappears, the valve plate 14 can restore to the original state, at the moment, although the garbage in the garbage collection net 33 can float upwards along with the buoyancy pipe, the phenomenon of flushing can not occur even if more garbage is blocked by the valve plate 14.

Because the collection device of the floating garbage on the water surface can normally collect the floating garbage only when the outer retainer ring 34 is 3cm below the water surface, when the water surface liquid level changes due to the rise and fall tide of the sea, a large lake and the like or other reasons, the liquid level sensor 47 reads the water surface liquid level in real time and feeds the water surface liquid level back to the electric cabinet 46, the electric cabinet 46 controls the waterproof motor 43 to move so as to drive the outer barrel 31 to lift along with the water surface liquid level, and the outer retainer ring 34 is ensured to be always 3cm below the water surface.

When the floating garbage collected in the garbage collection net 33 reaches the replacement requirement, the garbage collection net 33 needs to be replaced or cleaned, at this time, the submersible pump 32 is powered off, the submersible pump 32 stops draining, external water can slowly enter the outer barrel 31 through the gap between the buoyancy pipe and the outer barrel 31 and other positions, when the buoyancy of the buoyancy tube is larger than the gravity, the floating tube can float upwards to be 15cm higher than the water surface, even if the external water area blows wind or waves are generated, the floating garbage can not enter the outer barrel 31 to damage the submersible pump 32, meanwhile, after the buoyancy tube floats upwards, workers only need to turn the rubber ring inwards to be separated from the buoyancy tube and lift the garbage collection net 33 upwards to realize the disassembly of the garbage collection net 33, therefore, the garbage collection net 33 is convenient to replace or clean, when the garbage collection net 33 is replaced or cleaned, the submersible pump 32 is powered, and the water surface floating garbage collection device can continue to work.

In conclusion, with the adoption of the technical scheme of the utility model, the structure is simple, and the garbage collection net is convenient to replace; the position of the outer barrel can be adjusted in real time according to the liquid level change of the water surface; the buoyancy tube has strong tightness, can be manufactured by adopting a 3D printing process, and has simple process, low production cost and low price; the water surface floating garbage collecting device is provided with the one-way valve, so that the phenomenon that the water surface floating garbage collecting device is flushed due to more garbage in the garbage collecting net can be prevented.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
