A device for treating duckweed on the surface of lakes by using the principle of accompanying current

Abstract

The invention relates to the technical field of environmental protection and energy conservation, and discloses a device for treating duckweeds on lake water surface by using a wake flow principle. The device comprises a ship body, wherein a flow guide cavity is formed in the ship body, and a flow guide plate is fixedly arranged in front of the flow guide cavity; the ship body is fixedly providedwith a feeding pipe through an interception wing plate; a driving device is fixedly arranged at the rear part inside the ship body; and an electric rotating rod is movably arranged in the ship body, the electric rotating rod is movably provided with a protective cylinder through a bottom plate, and the outer wall of the electric rotating rod is fixedly provided with a crushing cutter set. According to the device for treating duckweeds on lake water surface by using the wake flow principle, the duckweeds are crushed by matching the electric rotating rod with the crushing cutter set, the water flow impacts the protective cylinder, a rotating shaft drives a lower overturning sheet to rotate, the crushed duckweeds can be extruded when being discharged, and the processed duckweeds are changed into feed which is easy to eat by fishes and shrimps; and the device has the advantages of fully utilizing the wake flow of the ship body, collecting the duckweeds and processing and utilizing the duckweeds.

Description

technical field [0001] The invention relates to the technical field of environmental protection and energy saving, in particular to a device for treating duckweed on the water surface of lakes by utilizing the principle of accompanying current. Background technique [0002] With the development of society, water environment pollution has gradually become the main restrictive factor for the sustainable development of my country's social economy. In water environment pollution, duckweed treatment is an important issue. Duckweed is a kind of floating plant, which often grows in paddy fields, ponds or other still waters, and is often mixed with other aquatic plants. Due to the characteristics of duckweed's easy reproduction, it is easy to form floating communities densely covered with water in waters. Such a large amount of duckweed will block the sunlight in the water area, making it impossible for fish and other aquatic organisms in the water to receive sunlight, and eventuall...
