Problems solved by technology

When studying and analyzing the water quality of a specific water depth, in the process of collecting water, the water above the water depth is easier to collect than the water at the depth, so the collected water is usually a mixture of water at the depth and water above the depth Therefore, it is impossible to accurately and effectively analyze the composition of the water at this depth
In the process of collecting soil ore at the bottom of the water, the sampling tools generally used are all spoon-shaped. Due to the influence of water flow, the collected soil ore is easy to fall off, and the efficiency is not high.

Abstract

The present invention belongs to the technical field of sample analysis, and relates to an underwater sample collection device and a sampling method thereof. The device comprises a t-branch pipe consisting of a first straight pipe, a second straight pipe and a third straight pipe, a holding cavity for mutual communication is formed among the first straight pipe, the second straight pipe and the third straight pipe, the holding cavity is internally provided with a moving ball capable of blocking the first straight pipe or the second straight pipe or the third straight pipe, the first, second and third straight pipes are all provided with electromagnet modules capable of driving movement of the moving ball, the third straight pipe is connected with a drainage pipe, the drainage pipe is provided with an air inflation mechanism capable of air inflation for the drainage pipe, and the first straight pipe and the second straight pipe are respectively connected with a first sampling barrel anda second sampling barrel. The underwater sample collection device and the sampling method thereof can collect water in special depth to improve the collection efficiency of soil ore sands at the bottom of the underwater.

Description

technical field [0001] The invention belongs to the technical field of sample analysis, and relates to an underwater sample collection device and a sampling method thereof. Background technique [0002] Whether it is scientific research or fish farming, it is necessary to collect and analyze underwater samples such as underwater water quality and soil mineral sand at the bottom. When studying and analyzing the water quality of a specific water depth, in the process of collecting water, the water above the water depth is easier to collect than the water at the depth, so the collected water is usually a mixture of water at the depth and water above the depth Therefore, it is impossible to accurately and effectively analyze the composition of the water at this depth. And in the process of collecting the soil ore at the bottom of the water, the sampling tools generally adopted are all spoon-shaped. Due to the influence of water flow, the collected soil ore is easy to fall off, ...
