Problems solved by technology

[0003] However, the traditional water quality monitoring sampling method has great defects. The sampling personnel put the sampling bottle with counterweight directly into the water to take water samples. The sampling area is relatively limited. Even if it is operated on a ship, it is impossible to accurately judge the sampling depth. Sampling Accuracy

Abstract

The invention discloses an accurate-positioning depth-adjustable water sample collection device, and belongs to the technical field of water sample collection, the accurate-positioning depth-adjustable water sample collection device comprises a pressure-resistant shell, the pressure-resistant shell is of an annular structure, the center of the pressure-resistant shell is provided with an inner cavity, and the inner cavity is communicated with the inner cavity; sampling cabins are uniformly arranged on the outer side surface of the pressure-resistant shell in a surrounding manner, a mounting groove is formed between every two adjacent sampling cabins, an ascending propeller assembly is fixedly mounted in each mounting groove through a bracket, a placement cavity is formed between the outer side wall of the inner cavity and the corresponding sampling cabin, and a connecting threaded sleeve is arranged on the side wall of each placement cavity; a liquid inlet port is formed in the center of the connecting threaded sleeve, and a liquid suction mechanism used for collecting liquid is installed in the connecting threaded sleeve. The sampling device can be automatically conveyed into a sampling water area with the accurate depth, sampling can be carried out at multiple depths at the same time, the sampling accuracy is high, and meanwhile sampling is convenient.

Description

technical field [0001] The invention relates to the technical field of water sample collection, in particular to a depth-adjustable water sample collection device with accurate positioning. Background technique [0002] In order to implement the important goal of water ecological environment protection, it is necessary to evaluate the water body pollution status through water quality and plankton monitoring, and propose targeted protection and restoration measures, and the collection of water samples is the most basic and indispensable part of data acquisition. [0003] However, the traditional water quality monitoring sampling method has great defects. The sampling personnel put the sampling bottle with counterweight directly into the water to take water samples. The sampling area is relatively limited. Even if it is operated on a ship, it is impossible to accurately judge the sampling depth. sampling accuracy. Contents of the invention [0004] 1. Technical problems to ...
