Abstract

A simple bottle-type water sample collector, especially a bottle-type water sample collector for water sample collection at different depths in surface water comprises a cylinder for accommodating a glass water sample bottle; a cover plate, and a draw ring are disposed at the upper end of the cylinder; a hinged support for connecting the cylinder is disposed at one end of the cover plate; a hasp is disposed at the other end; the cover plate can be opened by the hasp to put in or take out the glass water sample bottle; a bottle cap lasso is connected with the bottle cap of the glass water sample bottle; the draw ring is connected with a draw ring rope; a weight pedestal is connected with the bottom of the cylinder, which facilitates the water sample collector to sink to different depths underwater. The invention has the advantages of small size, convenient carrying, simple structure, and easy operation, and is convenient for water sample collection at different depths in rivers, lakes and seas.

Description

technical field [0001] The invention relates to a simple bottle-type water sample collector, in particular to a device for collecting water samples at different depths of surface water bodies (rivers, lakes and oceans). technical background [0002] With the development of economy and society and the acceleration of urbanization, a large number of point source pollution (domestic sewage, industrial wastewater) and non-point source pollution (rainfall runoff from cities and farmland) harmful to humans and other organisms are discharged into the environment without adequate treatment. Rivers, lakes and oceans have seriously polluted natural water bodies. Pollutants further expand their scope of influence through migration, diffusion and transformation in water bodies. Therefore, it is very necessary to monitor the water quality of surface water bodies (rivers, lakes and oceans). Water sample collection is an important part of water quality monitoring. In the process of water ...
