Deep water type water quality measurement multi-point sampling device

Abstract

The invention relates to a deep water type water quality measurement multi-point sampler comprising a power supply, a display instrument, a control switch, an upper-and-lower linkage valve, a liquid level transducer, and a sampler main body consisting of four sampling bottles; the sampling bottles are fixed by fixing rings, and then fixedly connected to the steel cable part at the bottom end of the cable connecting wire; the liquid level transducer at the bottom end of the cable conductor converts a water body signal in the sampling bottles into an electrical signal which is transferred to the display instrument for display through the integrated control switch; and the upper-and-lower linkage valve is merged into the cable conductor through a linkage valve control wire, and then connected to the control switch. The arrangement of the upper-and-lower linkage valve overcomes the technical difficulty in gas discharging in the prior deep water sampling; due to the modularized composition, the sampler is convenient and quick to assemble; the quantificational water sampling can be carried out at definite depth; the problem that the prior single-port water collection causes damage to the flow field is solved; and meanwhile, the valve can be switched on or off instantaneously, and the leak prevention effect is good. Therefore, the efficiency and the accuracy of deep water sampling are improved. With good practicability, the invention is easy to popularize and apply.

Description

technical field [0001] The invention relates to environmental water quality monitoring and hydrological measurement technology, in particular to a deep-water type water quality measurement multi-point novel sampler for monitoring and analyzing water body quality. Background technique [0002] With the increasing intensity and speed of water resources development and utilization and people's increasing awareness of ecological environment, water environment issues are gradually being paid attention to at home and abroad. At present, water environment is the focus of domestic environmental protection and project environmental assessment related work. Water quality elements, as water environment evaluation indicators, are important indicators to measure the degree of damage to water areas and whether drinking water is healthy. Accurate water quality indicators can provide a reliable basis for environmental protection, and water sample collection is an important part of the work. ...

Problems solved by technology

This also requires sampling and observation of deeper water bodies. Traditional sampling methods can only obtain surface water bodies, lack of reliable means to collect deep water water samples, and some methods of obtaining water samples by pumping water are inefficient, and the effect of depth determination is poor. Negative impact on subsequent analysis of water samples

There are some automatic sampling machines used in oceans in foreign countries, but they are expensive, complex engineering principles, high maintenance costs, and difficult to promote
