A special sampling device for environmental protection water body detection

Abstract

The invention discloses a special environment-friendly water detection sampling device which comprises a sampler body, a pressure balance device, a driving device and a wastewater sampling device. A low-pressure cavity and a high-pressure cavity are formed in the sampler body, the high-pressure cavity is formed in the low-pressure cavity, the bottom of the high-pressure cavity is connected with alower end cover, the lower end cover is fixedly mounted at the lower end of the sampler body, a flow guide pipe is inlaid into the lower end of the high-pressure cavity, the lower end of the flow guide pipe penetrates the inner wall of the lower end cover and is connected with the wastewater sampling device, the wastewater sampling device is fixedly mounted on the inner wall of a guide sleeve, theguide sleeve is fixedly mounted on the lower surface of the lower end cover, an external energy device is omitted, water in-situ hydrostatic pressure is directly used for driving the device to work,an energy utilization mode is simple and clean, the device is wider in sampling range and high in practicability and applicability, and the influence of underwater environments on sampling positions is reduced.

Description

technical field [0001] The invention relates to the technical field of a special sampling device for waste water detection, in particular to a special sampling device for environmental protection water body detection. Background technique [0002] Water is undoubtedly an important material indispensable to all life on this vast earth, and it is also an irreplaceable important natural treasure. However, due to the increase in population, the rapid development of industrial production, especially the rise of modern industry around the world, and more and more people flocking to cities, water resources have been unable to meet the needs of human society. In order to meet the ever-increasing demand for water, people have adopted many methods to expand the development and utilization of water resources. On the one hand, because of the continuous large-scale development and utilization of water resources by human beings, certain benefits have been achieved in terms of economic de...

Problems solved by technology

[0005] (1) The sampler for industrial wastewater can only take the liquid part of the wastewater at present. For the turbid waste liquid, it is easy to cause the sampling tube to be blocked after using the sampler, and the cleaning of the sampling tube is troublesome;

[0006] (2) The driving device of the existing waste water sampling pipe is basically powered by the outside, but the water pressure at the bottom of the deep river will bring some troubles to the sampling, and the first external driving device cannot follow the sampler to enter The drive is provided in the water, and the sampling direction of the second sampling tube cannot be fixed. It is difficult to sample the water quality in a small area, which makes the test results easily affected.
