System for automatically collecting, classifying and preserving water ecological sample, and synchronous monitoring and collecting method

Abstract

The invention discloses a system for automatically collecting, classifying and preserving a water ecological sample, and a synchronous monitoring and collecting method. An automatic overwater water ecological monitoring and sampling platform, a sample and data conveying pipeline and a tower type sample classifying and preserving device are scientifically designed, and are connected with a system control terminal to form an automatic sampling and monitoring system. The system can respectively transmit (convey) acquired water quality, flow velocity, fish and other data and the water sample to anashore data acquisition terminal and the tower type sample classifying and preserving device to simultaneously achieve online monitoring of the water quality, the flow velocity and other water environment factors and the collection of the water ecological organism sample. The system and the method have the advantages of reliability in monitoring and sampling, high efficiency, high applicability,and facilitation of standardization and unitization of water ecological monitoring and water ecological sampling.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, and more specifically, to an automatic collection and classified preservation system of water ecological samples and a method for synchronous monitoring and collection. Background technique [0002] With the rapid development of China's water conservancy industry in recent years, the hydroelectric cascading development of major river basins has gradually deepened and become more and more complete, and the utilization rate of hydropower resources has greatly increased. The construction of cascade hydropower dams has blocked the river basin, fragmented the river and turned it into a reservoir, which has brought about a series of water ecological environment problems, especially the major impact on aquatic organisms. River ecological monitoring is the biological monitoring of the ecological health of the river at the ecosystem level. It uses various techniques to measure and an...
