A water body, organism, and sediment collector suitable for different water body environments

Abstract

The invention discloses a water, organism and deposit collector suitable for different water environments. The collector comprises a bottom-open cylinder and a stirring shaft, the upper part of the cylinder is provided with a rotatable bearing port, the stirring shaft is installed at the bearing port, and the bottom end of the stirring shaft is inserted into the cylinder, the bottom end of the stirring shaft is also equipped with at least three brushes with different heights from a deposition plane, the top of the stirring shaft is provided with a handle for rotating the stirring shaft, and the side wall of the cylinder is also provided with an outlet. The collector provided by the invention realizes the triple effects of collecting the organisms, water and deposited soil from water deposition environments, is equipped with different bottom devices, can realize device recombination according to different sampling needs of users to achieve switching use of corresponding functions. At the same time, the invention solves the problem of difficult sampling of organisms and soil from rough and stony deposition environments in existing collectors.

Description

technical field [0001] The invention relates to the technical field of environment monitoring data source collection, in particular to a water body, organism and sediment collector suitable for different water body environments. Background technique [0002] The research on the water body environment not only needs to test the water quality, but also needs to sample the organisms and sediments in the water and bottom. At present, collectors for obtaining sediments in deep water generally include grab-type, box-type, etc. These collectors have complicated mechanisms, inconvenient operation, huge equipment, and high costs, and are not suitable for various unknown environmental water bodies during field exploration. , biological, sediment collection. [0003] The Chinese patent application with the publication number CN2859505Y discloses a gravity type columnar sampler, which falls into the water by its own weight and automatically caps or bottoms, but it fails to solve the pr...

[0003] The Chinese patent application with the publication number CN2859505Y discloses a gravity type columnar sampler, which falls into the water by its own weight and automatically caps or bottoms, but it fails to solve the problem of some hard objects and some living objects in the sediment layer. It is difficult to control its landing position and depth. In addition, its structure is relatively complicated, and it is not convenient to carry. The actual use effect is not ideal.
