Water sample gatherer and water quality detection system

Abstract

The invention provides a water sample gatherer and a water quality detection system. The water sample gatherer comprises a water collector, a water conduit, a flow diversion pipe and a water storage tank connected orderly. The water quality detection system comprises the sample gatherer and a water quality detection probe arranged in the water storage tank of the sample gatherer. The water quality detection system has a simple structure, can be installed and operated simply, and can take a water sample under the water surface out of the water surface without applied power and carry out water quality monitoring. The water sample gatherer and the water quality detection system are suitable for a field environment and are especially suitable for high-speed movement or high-speed water flow conditions. The water quality detection system can realize fast, accurate, continuous and automatic collection of a water sample at fixed water depth of a water surface layer, can realize accurate unmanned on-line synchronous detection of the quality of water at a sampling position, has an accurate water quality analysis result, and can really reflect a water quality distribution state.

Description

technical field [0001] The invention relates to a water sample collection device and a water quality detection device, in particular to a continuous and automatic water sample collector and a continuous and real-time water quality measurement system. Background technique [0002] In the scientific research and management of water environment protection, the collection of representative water samples and the determination of water quality indicators are one of the most important basic tasks. In order to grasp the distribution of water quality indicators in the water body, it is necessary to continuously collect water samples and online simultaneous determination of water quality indicators at multiple locations and fixed water depths in the water body. [0003] At present, there are many studies on water sample collection and measurement devices, and a variety of commercial samplers have been developed, which can perform stratified sampling of water samples with different req...

AI Technical Summary

Problems solved by technology

The utility model has the advantages of simple structure, easy operation, high precision of fixed-point collection of water samples, and is convenient for water quality inspection departments to use, but the sampler is only suitable for fixed-point sampling, not suitable for continuous automatic water sample collection under high-speed moving state

[0006] The above-mentioned existing water sample sampling device or equipment can only perform manual fixed-point sampling, and manual water sample collection can only be implemented when the sampling carrier is stationary or moving at a low speed. Unable to achieve simultaneous determination of water quality indicators

In addition, when the water quality measurement probe is placed in the water, it is difficult to keep the probe at a fixed depth due to the high-speed movement of the vehicle or the high flow velocity of the water quality detection probe. accuracy

It cannot quickly, accurately and continuously collect water samples at a fixed water depth, and perform accurate online simultaneous determination of the spatial distribution of water quality indicators at this depth
