AI Technical Summary

Technical Problem

In existing technologies, due to the complex environment at the bottom of the water body, the bucket of the sampling tool cannot completely close when it encounters impurities such as stones, resulting in the loss of silt and causing large errors in the detection results.

Method used

A quantitative collection tool for benthic animals was designed, which uses two interlocking arc-shaped shells and a protective mechanism including an extension rod, a crossbar, and a pointed conical insert to prevent stones from getting stuck in the shells and to ensure effective closure of the container.

Benefits of technology

This effectively prevents impurities such as stones from affecting the closure of the collection tool, ensuring the integrity of the collection process and the accuracy of the test results.

Abstract

The utility model relates to benthic animal collection technical field discloses a kind of benthic animal quantitative collection tools, including two mutually hinged arc shell, the arc shell is equipped with connecting column, one side the arc shell is equipped with the support rod of two sides corresponding arrangement, rotatingly equipped with the clamping plate between the support rod, the clamping plate is equipped with clamping groove, the utility model compared with prior art advantage lies in, by setting extension rod, cross bar and insert block, when collecting, arc shell sinks into water body bottom, water body bottom is relatively soft and insert block end is sharp cone, so that insert block is easily inserted, when encountering stone, arc shell no longer moves down, so that when two arc shells approach each other, stone cannot be clamped.
