Method for collecting broken garbage on water surface

Abstract

The invention provides a method for collecting broken garbage on a water surface. The method comprises the following steps that a water pump is started, water in an outer barrel is discharged out of the outer barrel through the water pump, the water level in the outer barrel is lowered, and an inner barrel floating in the water in the outer barrel moves downwards due to lowering of the water level; the water continues to be discharged, when the inner barrel descends to a certain position to meet the requirement that water outside the outer barrel crosses an upper port of the inner barrel to be injected into the inner barrel, the water level in the outer barrel gradually rises again, and at the moment, the inner barrel moves upwards; when the inner barrel moves upwards, water injection is reduced, and the inner barrel moves downwards, so that the inner barrel moves up and down repeatedly below the water surface; and the water pump continuously works, the water outside the outer barrel flows towards the center of the inner barrel, garbage on the water surface flows into the inner barrel along with a water flow, and a garbage breaking device is fixed in a water suction opening of the inner barrel or a space of a filter screen arranged on the inner side of the inner barrel and breaks the collected garbage to the particle size capable of penetrating through the filter screen. According to the method, continuous collection of garbage can be achieved.

Description

technical field [0001] The present application relates to the technical field of automatic water surface garbage collection, in particular to a method for collecting broken water surface garbage. Background technique [0002] As we all know, the current water environment situation in my country is very severe, and the total discharge of water pollutants is very large, among which the solid waste pollutants discharged in the water and left on the water surface are even more unbearable. Traditional water surface garbage collection methods include manual fishing with nets and damming with grids or filter screens. However, manual fishing with nets is too inefficient and consumes too much manpower. Blocking with grilles or filter screens affects flood discharge in this water area and garbage deposits affect the appearance. The existing mature marine garbage collection ships and river cleaning ships are too large to be used in small water sources and narrow rivers with many bends...

Problems solved by technology

[0004] In order to solve the problem in the prior art that the cleaning effect is reduced due to cleaning and replacement of the filter screen in some cases, this application provides a method for collecting broken water surface garbage, the device used can automatically suck the water surface garbage into the filter screen, and Garbage crushing device is installed in the suction port of the device or in the filter screen, and the crushed garbage and water pass through the filter screen together and are discharged from the device
