Problems solved by technology

These water extractors have high requirements on the well hole, the sampling depth is limited, and the structure of the water extractor itself is relatively complicated. Each time the water sample needs to be custom-made, such as conduits, flower tubes, hoses, etc., the cost of water intake is high and the operability is not strong.

Abstract

A layered water intake device includes a water intake device body (5); the lower part of an inner cavity of the water intake device body (5) is provided with an anti-floating counterweight body (6), and the upper part of the inner cavity of the water intake device body (5) is provided with limiting clamps (4); the inner side of a seal port of the water intake device body (5) is provided with a fixed sealing clamp (3-2); the upward side of the limiting clamps (4) of the inner cavity of the water intake device body (5) is provided with a mobile sealing clamp (3-1) which can move upper and down; the mobile sealing clamp (3-1) and a movable shaft (2) are connected with each other or are formed as a whole; one end of a descending measuring rope (1-1) is connected with the movable shaft (2); one end of one lifting measuring rope (1-2) and one end of the other lifting measuring rope (1-2) are respectively connected with two lugs outside the upper part of the water intake device body (5). The layered water intake device has the advantages that when used for layered water intake of river, rivus, lake and sea water bodies, the layered water intake device can perform continuously layered water intake at a same water intake plane position according to different depths, and also can effectively guarantee the accuracy of fetched water samples; and when layered water sample fetching is carried out in exploratory boring holes or hydrological water wells, the layered water intake device has no special requirements on hole wells, is convenient and concise to sample and higher in efficiency, and has wide application value.

Description

technical field [0001] The invention relates to the technical field of water resource survey and geotechnical engineering survey water sampling, in particular to the technical equipment for stratified water sampling in survey boreholes and in rivers, lakes and seas. Background technique [0002] In engineering survey and water resources survey, it is sometimes necessary to draw water in different layers of groundwater to test the chemical composition of water samples at different depths, so as to evaluate water quality and corrosivity of groundwater, especially for coastal projects. The relationship between fresh water and sea water is in contact with each other. Therefore, it is necessary to take water in layers at different depths for water quality analysis to find out the interface between fresh water and sea water, so as to facilitate targeted anti-corrosion design and reduce project investment. [0003] At present, there are stratified water extractors for underground w...
