Shallow water type water quality measurement sampler

Abstract

The invention relates to a shallow water type water quality measurement sampler, and belongs to the field of water environment conservation and monitoring. The sampler comprises a sampling bottle, a holding rod and a stay guy, wherein, an upper linkage valve is arranged at the neck part of the upper end of the sampling bottle; a lower linkage valve is arranged at the neck part of the lower end; the upper linkage valve is connected with the lower linkage valve through a valve linkage rod; one end of the stay guy is connected with the top end of the holding rod, and the other end of the stay guy is connected with the valve linkage rod which is connected with the upper linkage valve and the lower linkage valve; and the sampling bottle is connected with the lower part of the holding rod by using a fixing ring. The invention can carry out the located and quantitative sampling quickly and accurately for a plurality of times; the problem that the traditional single-port water collection causes damage to the flow field is solved, and the technical difficulty of the traditional sampler in discharging air in water is solved; the sampler is portable and has low cost and construction price; the sampler can be adapted to the demands for field monitoring work, and extends the range of the traditional manual sampling; and the effective sampling can be carried out in positions difficult for sampling, such as sewage disposal ports and the like, and the influence of anthropic factors on the sampling is reduced.

Description

Shallow water water quality measurement sampler technical field The invention relates to environmental water quality monitoring and hydrological measurement technology, in particular to a shallow water type water quality measurement sampler used for monitoring and analyzing water body quality. Background technique With the increasing intensity and speed of water resources development and utilization, and the increasing awareness of people's ecological environment, water environmental 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. [Zhao Wenqian. Environmental Hydraulics [M].

Problems solved by technology

On the other hand, in terms of sampling frequency, sampling volume, and field operations, the actual water samples taken are mostly water samples on the shore and within the human reach of the surface, which are insufficient in terms of representativeness and reliability.

In addition, the sampling of polluted and toxic water lacks the necessary protective measures for operators
