Stratified sampling device for environmental protection water quality detection

Abstract

The invention discloses a layered sampler for environmental protection water quality detection, which comprises an outer tube body and an inner shaft rod sleeved in the inner cavity of the outer tube body, one end of the outer tube body is a sealing end, and the outer tube body corresponds to it The other end of the inner shaft is provided with a sealing plate that is penetrated by the inner shaft, and the end of the inner shaft close to the sealing plate is equipped with a screw disk, and several sampling cavities are opened inside the inner shaft along its axis direction, and The outer surface of the inner shaft on one side of the sampling chamber is sleeved with a rotating sleeve, and the sampling chamber is connected to the water inlet chamber inside the rotating sleeve through the water channel opened on the inner shaft, and the water inlet chamber on one side A water inlet with a circular structure is opened on the surface of the outer tube body, and a connecting sleeve connected to the mouth of the sampling cup is provided on one side of the water inlet, and a rotary seal is installed at the connection between the inner shaft and the rotating sleeve. The invention has reasonable structural design and simple operation, and the whole structural main body is a rod-shaped structure, which is convenient to carry and store.

Description

technical field [0001] The invention relates to a sampling device, in particular to a layered sampler for environmental protection water quality detection, which belongs to the technical field of environmental protection detection application. Background technique [0002] With the growth of world population and the development of industrial and agricultural production, water consumption is also increasing. At the same time, due to the production and life of human beings, the surface and underground water bodies are polluted, and the water quality deteriorates, which makes the limited water resources more tense. In the case of such a shortage of water resources, we must cherish water resources more. At the same time, the testing department should do a good job in testing to provide protection for the health of the people. Water testing is related to people's livelihood and should not be underestimated. Water quality testing and sampling are the key to water quality testing ...

Problems solved by technology

[0003] In order to better detect the water quality of a certain water area, it is often necessary to extract water at different depths as samples for testing. Most traditional samplers need to extract multiple times, which is inefficient. At the same time, some samplers that can extract samples at different depths require additional source of power, increasing the production cost and use cost of the sampler
