Vertical stratification water sample synchronous sampling device and sampling method thereof

Abstract

The invention relates to a water sampling device used in research of geoscience and environmental science, and particularly relates to a vertical stratification water sample synchronous sampling device and a sampling method thereof. The device is of a frame structure consisting of four vertical strip square columns and an upper horizontal sealing surface and a lower horizontal sealing surface, other surfaces are open, the frame is a hollow cube, vertical through clamp slots are formed in two adjacent vertical surfaces of the two vertical strip square columns facing the center of the cubic frame structure, sealing movable panels are inserted between every two vertical clamp slots, the sealing movable panels comprise a front panel, a rear panel and side panels at two sides, four vertical surfaces of the cube are sealed and wrapped so as to form a hollow inner cavity, the cube is divided into layered sealing interlayers by anti-leaking flexible partition clothes layers and the sealing movable panels, sampling holes are respectively formed in sealing movable panels of each equal distance sealing interlayer, two ends of the transverse clamp slot are connected with the front panel and the rear panel, and the transverse clamp slots are arranged with equal intervals in a mobile guide slot of the joint part of the side plate and the sealing movable panel.

Description

technical field [0001] The invention relates to a device for collecting water samples in geoscience and environmental science research, specifically, a vertical layered water sample synchronous sampler and its sampling method, which is suitable for layered water sample collection in shallow lakes and rivers . Background technique [0002] Water sample collection is one of the necessary tools for lake environment and ecosystem research. The water sample collection device in the prior art is generally about 50 cm high, and the collected water sample is generally a mixed sample body with a thickness of 50 cm. distribution studies. When conducting research on the vertical distribution characteristics of lake physical, biological and chemical parameters, especially the distribution characteristics near the interface, these samples are difficult to meet the research requirements. In addition, lake research usually requires synchronous collection of water samples in different w...
