Video Aquatic Sampling Methods

Abstract

Provided are a video sampler for aquatic organism and a sampling method. Recently, along with the rapid development of industries along rivers and lasting of global greenhouse effect, pollution to the river and lakes is on the rise. The video sampler for the aquatic organism comprises a casing (1) provided with a lofting valve (11). The lower end of the casing is connected with a lower end cover (3) provided with a lower cone movable door (2), the upper end of the lower cone movable door is connected with a sampler lower movable door connection door inner ventilating cavity (4), a cable line (5) is installed in the sampler lower movable door connection door inner ventilating cavity, and the lower end of the lower cone movable door is connected with a video angle-rotatable camera (6) through a cable line, the sampler lower movable door connection door inner ventilating cavity and the cable line penetrate through an upper cover (7), a compression spring (8) is sleeved outside the sampler lower movable door connection door inner ventilating cavity and is supported by a lower support ring (9), and a water temperature sensing probe (10) is connected to the outside of the sampler lower movable door connection door inner ventilating cavity. The video sampler for the aquatic organism and the sampling method are used for sampling the aquatic organism.

Description

[0001] Technical field: [0002] The invention relates to a video aquatic organism sampler and a sampling method. [0003] Background technique: [0004] In recent years, with the rapid development of industries along the river and the continuation of the global greenhouse effect, the pollution of rivers, rivers and lakes has become increasingly serious. Directly affect the sound development of animal husbandry and agriculture, especially serious pollution to the quality of people's daily drinking water; directly change the sustainable virtuous cycle of the biological chain of aquatic organisms in rivers, rivers, and lakes, causing many aquatic organisms to be on the verge of extinction the edge of. For example, oily sewage from oil refineries, residual chemical waste from chemical plants, and other nuclear material leaks caused by the Japanese tsunami are threatening aquatic organisms in adjacent sea waters, which have received great attention from the state. Tracking and ce...
