A lake deep water quality monitoring sample extraction device

Abstract

A device for extracting samples for lake deep-layer water quality monitoring, comprising a frame body, a cavity is arranged in the frame, and a test tube assembly for holding deep-layer water is connected to the lower inner wall of the cavity, and the upper part of the cavity is The side inner wall is connected with a connecting cavity, and the right inner wall of the connecting cavity and the right inner wall are provided with a trigger device, and the trigger device can pass through the deep layer when the device of the present invention descends to a preset depth underwater. The strong water pressure triggers and makes the external deep water enter the connecting cavity and the cavity. A fixed block is fixedly arranged on the right inner wall of the connecting cavity, and the fixed block and the frame are set There is a partition-floating component, and the present invention aims to design a water quality sample extraction device that can facilitate the extraction of deep water samples from lakes and avoid the influence of shallow water on the samples during the extraction process.

Description

technical field [0001] The invention relates to the technical field of water quality sample extraction, in particular to a lake deep water quality monitoring sample extraction device. Background technique [0002] At present, lakes, rivers, and seas in China have been polluted to varying degrees. In order to control water quality, it is necessary to master the conditions of various parameters in the water. There is an ancient saying that if a worker wants to do a good job, he must first benefit his own device. This is also the same reason. If you want to control the water quality well, you must first detect the content of each parameter in the water. If you want to achieve better results, you need online real-time detection, so as to ensure that the treated water quality meets the standards; [0003] When extracting lake water quality testing samples, it is necessary to extract relatively deep water for water quality testing. The traditional way of extracting deep water qua...

Problems solved by technology

[0003] When extracting lake water quality testing samples, it is necessary to extract relatively deep water for water quality testing. The traditional way of extracting deep water quality samples is directly through the bucket. The impact of shallow water will eventually lead to inaccurate test results. Therefore, the present invention aims to design a water quality sample extraction device that can facilitate the extraction of deep lake water samples and avoid the influence of shallow water on the samples during the extraction process.
