A device for collecting plankton on the surface of a river

Abstract

The invention discloses a device for collecting plankton on the surface of a river, which includes a floating plate, a toggle assembly for pushing plankton on the water surface is installed on the outer side of the front end of the floating plate, and collectors for collecting plankton on the water surface are installed on both sides of the floating plate device, the invention detects the plankton on the surface of the river through the solar power generation panel and the sensor assembly at the bottom, and utilizes the rotation of the toggle motor in the front-end collection device of the floating plate to drive the rotation of the spiral stirring page and play a drainage effect, so that The plankton on the river surface gathers towards the front, and then pushes the plankton on the river surface to the conveying parts at both ends through the cooperation of the toggle plate, so as to realize the collection of the plankton on the river surface and solve the current difficulty in sampling the plankton on the water surface. It is convenient to carry out biological monitoring of river water quality, predict the trend of river water quality changes, and take early measures to protect and restore river water quality.

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
