Layered water sampling and filtering integrated device and water sampling method

Abstract

The invention relates to a layered water sampling and filtering integrated device which comprises a floating mechanism, a telescopic mounting rod is mounted on the lower surface of a circular balanceplate of the floating mechanism, and a movable water inlet head is mounted on the telescopic mounting rod; the circular balance plate is provided with a sampling mechanism, the sampling mechanism comprises a plurality of units, the units are uniformly distributed along the inner circumference of the circular frame, each unit comprises a tank body, a piston and a lead screw, the top end of each screw rod extends out of the upper part of the tank body and is welded with a gear, and the bottom end of the tank body is communicated with the upper part of the movable water inlet head through a threaded hose; a rotating shaft fixedly provided with a rear driving gear is hinged to the circular frame, the top of the rotating shaft is connected with a motor, and the driving gear is connected with the gear of each unit in a meshed mode. The invention further comprises a water sampling method which is simple and convenient to operate and capable of sampling water bodies with different depths, multiple samples can be obtained at a time, the water body sampling efficiency is improved, and by arranging the filtering mechanism, the experiment steps are greatly simplified.

Description

technical field [0001] The invention belongs to the technical field of water collection, and relates to an integrated device for collecting and filtering water bodies, in particular to an integrated device for collecting and filtering layered water and a method for collecting water. Background technique [0002] "Black and white bottle method" is a commonly used technical method in ecology, generally used to determine the primary production of producers in aquatic ecosystems, that is, the amount of solar energy fixed by photosynthesis of green plants in the ecosystem, or the amount of organic matter produced , the amount of oxygen produced, and the first step of the "black and white bottle method" is to collect water. After collecting the water source, it is then filtered. Because the water quality collected is mainly rivers and lakes, the water quality contains a large number of particles of different sizes and impurities, and the use of ordinary collectors needs to be equi...

AI Technical Summary

Problems solved by technology

The present invention provides a layered water sampling device for river treatment water body sample detection, which can solve the problem that most of the existing water sampling devices can only take one water sample at a time. When multiple water samples at different depths need to be collected, multiple The sampling efficiency of water body is low, and the traditional water sampling device or the existing layered water sampling device in the process of raising the water sampling device from the water layer to the water surface, the water samples in it may be different from those of different water samples. The water body in the layer is exchanged, and the water collector cannot sample the water body at a specific depth, etc.
