Collecting device for plankton on surface of river

Abstract

The invention discloses a collecting device for plankton on the surface of a river. The collecting device comprises a floating plate, wherein stirring assemblies used for pushing the plankton on the surface of water are installed at the outer side of the front end of the floating plate; and a collecting unit used for collecting the plankton on the surface of the water is respectively arranged at two sides of the floating plate. According to the invention, through solar power generation panels and a sensor assembly at a bottom part position, the plankton on the surface of the river is detected;by utilization of rotation of stirring motors in the collecting units at the front end of the floating plate, spiral stirring blades can be driven to rotate, so a drainage effect is exerted, and theplankton on the surface of the river is gathered towards a front end position; through cooperation of stirring plates for circular pushing, the plankton on the surface of the river are pushed into conveying pieces at two end positions, and collection of the plankton on the surface of the river is achieved, so the actual problem of difficult sampling for the plankton on the surface of the water inthe prior art is solved, and biological monitoring on the water quality of the river and prediction of the change trend of the water quality of the river can be conveniently carried out for taking measures as soon as possible and protecting and repairing the water quality of the river.

Description

technical field [0001] The invention relates to the technical field of river water quality detection, in particular to a river surface plankton collection device. Background technique [0002] Plankton refers to floating organisms that live in water and lack the ability to move effectively. They are divided into phytoplankton and zooplankton. Most plankton live on the surface of the water with the current. [0003] Plankton is an important part of river aquatic organisms. They are not only producers, such as algae, which provide food for other micro organisms, but also predators and secondary producers, such as protozoa, which feed on bacteria and algae, and at the same time, are preyed on by fish, in the water body material cycle and energy Mobility plays a very important role. Because of their simple structure, short life cycle, rapid response to pollution, and sudden changes in the water environment can be reflected in community changes in time, they are ideal environme...

AI Technical Summary

Problems solved by technology

[0004] However, plankton float on the water surface, are relatively scattered, and involve a wide area of ​​water area. Sampling work often requires hiring ships and workers, which is time-consuming and laborious and difficult to carry out. An energy-saving, flexible, and easy-to-carry sampling tool is urgently needed to complete sampling. For this reason, We propose a river surface plankton collection device
