An intelligent control device for water quality sampling

Abstract

The invention discloses a water quality sampling intelligent control device and belongs to the technical field of water body sample acquisition. The device mainly comprises a sealing casing, an actionrelease mechanism, an electronic self-control mechanism, an underwater sounding mechanism and a data input and display mechanism; the electronic self-control mechanism comprises a single chip microcomputer, a pressure sensor and the like. Before sampling operation is started, preset water depth data are input through the data input and display mechanism; when equipment is dropped to an appointedwater depth, the pressure sensor starts to work; as a control center, the single chip microcomputer controls the underwater sounding mechanism to beat the sealing casing to make sound; at the same time, an electromagnet is controlled to power off by the single chip microcomputer, an electromagnet sucker in the action release mechanism is dissociated from the electromagnet under the action of tension of a tension spring, and then a sampler hanging ring is unhooked. The water quality sampling intelligent control device has the beneficial effects of being small in size, simple in structure and simple and convenient to operate; the sampling efficiency can be improved, and the equipment can be used in match with multiple types of acquisition equipment, so that functions of automatic water depthsensation, wireless underwater working signal transmission and sampling action release can be achieved.

Description

technical field [0001] The invention belongs to the technical field of water body sample collection, and in particular relates to an automatic control device for water quality sampling of reservoirs. Background technique [0002] With the development of our country's social economy, the water environment problems our country is facing are becoming more and more prominent, and the corresponding water environment protection has become an important strategic choice for our country's sustainable development. For water environment protection, the most basic work is to master and understand the state of water environment. Water quality monitoring is an important means to master and monitor water quality status and understand water environment conditions. [0003] The first step in water quality research is to obtain representative water quality samples, which is also a key link in water environment investigation and monitoring. However, to fully understand the water environment, ...

AI Technical Summary

Problems solved by technology

[0005] The sampling work for reservoirs, especially water source reservoirs, has the characteristics of high sampling frequency and small scale compared with the marine environment. At this stage, the automatic sampling equipment for the marine environment is large in size and weight, and it needs to be lowered with the help of winches and other tools when working, and the price is also relatively high. High, not suitable for sampling work in reservoirs

[0006] Moreover, there is no automatic sampling device for sampling in reservoirs at this stage. Therefore, it is necessary to develop a water quality sampling device for reservoir water quality sampling that is efficient, lightweight, high-precision water depth sensing, and automatically controlled.
