The traditional water surface garbage collection method comprises the steps of manually salvaging with a net and setting up a grating or a filter screen for blocking a dam. The manual net salvaging efficiency is low and the labor intensity is high.

In the use process of the existing water surface garbage can, when the water pumping quantity of the water pump is equal to the water inlet quantity of the can mouth, balance is easy to be achieved at a certain water surface depth position, the water inlet quantity of the can mouth is insensitive, small change of the water inlet quantity cannot be timely sensed, larger inner barrel sinking actions cannot be timely made when the water inlet quantity of the water surface floaters with larger volume is close to the generated water inlet quantity change, the water surface floaters with larger volume are caused to stay at the can edge and cannot be collected into the can, and the collection effect of the water surface floaters with larger volume is poor.

The working principle of the water surface garbage can is as follows:

after the water pump 6 is started, the water in the outer barrel 3 is continuously pumped out by the water pump 6, the water level in the barrel is reduced, the volume of the submerged inner barrel 1 is reduced, and the buoyancy of the submerged inner barrel 1 is reduced. When the weight of the submerged and floating inner tub 1 and the filter screen 5 and the objects collected in the filter screen 5 (collectively referred to as a float moving member) is lower than the buoyancy, the float moving member starts to sink. When the upper end of the inner sinking and floating barrel 1 sinks below the water surface, external water flows into the inner sinking and floating barrel 1 from the barrel opening at the upper end of the inner sinking and floating barrel 1. When the float moving member sinks to a certain position, the amount of water flowing in from the outside is basically equivalent to the amount of water pumped by the water pump. At this time, as long as fluctuation of the water surface or any other factors influence the water flow change, for example, when a larger-volume floater reaches the edge of a barrel opening, the water quantity flowing into the barrel is suddenly reduced, the water quantity pumped by the water pump 6 is larger than the water quantity flowing in, and due to the nonlinear characteristic structure of the water volume with the large upper part and the small lower part, the water level in the outer barrel 3 is accelerated to drop, the sinking and floating inner barrel 1 is accelerated to sink, and the larger-volume floater can flow into the sinking and floating inner barrel 1 to finish collection. When the amount of water flowing in is greater than the amount of water pumped by the water pump, the float moving member starts to rise. Thus, the float moving part of the water surface garbage can continuously rises and falls along with the fluctuation of the water quantity, and is suitable for collecting the floats on the water surface with different sizes.

The side wall 3.1 of the outer barrel 3 is provided with a step part 3.12 except the inclined part 3.1, so that the water volume space of the outer barrel 3 has abrupt cross section changes on different horizontal cross sections, the balance state of the extracted water quantity and the inflow water quantity is disturbed, the sensitivity of the water surface garbage can to different inflow water quantities is improved, and the collection of floaters with larger volumes is facilitated.

Due to the nonlinear characteristic structure of the water volume with the large upper part and the small lower part, the utility model can automatically sensitively sense the approach of different floaters and adjust the up-down floating amount with different amplitude to collect the floaters for the high sensitivity of the water volume change in the barrel. When the floaters with smaller volumes are close to each other, the blocking disturbance to the water flow at the edges of the barrel is smaller, the water quantity pumped by the water pump is not much larger than the water quantity flowing in from the opening of the barrel, and the sinking amount of the sinking and floating inner barrel 1 is smaller, so that the collection can be completed. When the floaters with larger volume are close to each other, the blocking disturbance to the water flow at the edge of the barrel is larger, the water quantity pumped by the water pump 6 is larger than the water quantity flowing in from the opening of the barrel, and the sinking quantity of the sinking and floating inner barrel 1 is automatically increased to finish collection.

When the water level outside the water surface garbage bin is reduced, the water level gauge assembly 16 senses the water level reduction, and the device starts the descending function of the lifting device 14 according to the water level reduction signal, so that the device is wholly lowered to a proper water level. When the water level rises, the water level gauge assembly 16 senses the rise in water level and the device activates the raising function of the lifting device 14 in response to the water level rise signal, causing the device as a whole to rise to the appropriate water level.
