A cleaning boat for removing duckweed and weeds in water and its control method

Abstract

The invention discloses a cleaning vessel for removing duckweed and weeds from water, which includes a vessel body, a traveling device, and lawn mower. The cleaning vessel is characterized in that a capture net box is arranged below the vessel body, a temporary storage net box is arranged at the rear end of the vessel body, and the rear end of the capture net box communicates with the front end of the temporary storage net box; the capture net box consists of two middle vertical bars, two rear vertical bars, two side horizontal bars, a front horizontal bar and a mesh, the mesh is in a U shape and fixed to the middle vertical bars, the rear vertical bars, the side horizontal bars and the front horizontal bar, and a plurality of balancing weight blocks are fixed to the front horizontal bar at intervals; and a net lifting motor is fixed to the front end of the vessel body. According to the cleaning vessel, the capture net box collects the floating duckweed, fallen leaves, and cut emergent aquatic plants and submerged plants, the collected fallen leaves and aquatic plants pass the capture net box and enter the temporary storage net box at the rear end, workers salvage the fallen leaves and aquatic plants in the temporary storage net box to the vessel body, and the problem of eutrophication of water quality is solved.

Description

technical field [0001] The present invention relates to a cleaning boat and its control method, more specifically, to a cleaning boat and its control method for removing duckweed and weeds in water. Background technique [0002] Eutrophication of water body is the main factor for the deterioration of water quality in inland rivers and lakes. Eutrophic water body contains excess nitrogen and phosphorus elements, which will lead to the breeding and growth of aquatic plants. Excessive aquatic plants will consume COD in water. This leads to hypoxia in the water body, and the hypoxic water body will lead to the death of aquatic animals. Without aquatic animals, aquatic plants such as duckweed and submerged plants cannot be consumed, and the corruption of aquatic plants will further aggravate the deterioration of water quality. For rivers with trees planted on both sides, the daily leaf fall of trees is also one of the reasons for increasing water quality deterioration. [0003] ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem of excessive phytoplankton and fallen leaves of trees in the water body, the common method now is to use the method of manually salvaging fallen leaves to clean up. The staff drives a small boat and uses intercepting nets to beat the floating phytoplankton and fallen leaves to the shore. Low, and cannot handle emergent and submerged plants

There are also some cleaning boats on the market that automatically salvage phytoplankton in the water. An interception net is arranged at the bottom of the ship. As the hull advances, the floating leaves and plants will automatically enter the interception net. However, in the actual work process, Fallen leaves and aquatic plants will be attached to the intercepting net, causing the resistance of the ship to become extremely large. For cleaning ships powered by batteries, the driving force may be smaller than the resistance, resulting in the inability of the hull to travel and normal cleaning operations
