Water sampler capable of synchronously collecting multilayer water samples at fixed depth

Abstract

The invention discloses a water sampler capable of synchronously collecting multilayer water samples at fixed depth. The water sampler is mainly composed of a handle, a reel, a load bearing band, a lifting rope, floating bodies, water sampling units and a carrying idler, wherein scales and fixing holes are formed in the load bearing band, the floating bodies and the water sampling units are fixed on the load bearing band, and the positions of the floating body and the water sampling unit and the number of the water sampling unit can be determined according to actual demand. The plurality of water sampling units are fixed on the load bearing band of the device to collect water samples on the same vertical section in different depths, the obtained water samples are accurate, and the operation is simple. The assemblies of the device are detachable and are simple to assemble and convenient to carry, thereby being suitable for quick collection of field water samples.

Description

technical field [0001] The invention relates to the field of environmental detection and scientific research equipment, in particular to a water sample collection device suitable for surface water bodies such as rivers, lakes and reservoirs. Background technique [0002] Water sample collection is the basis and key link in water quality investigation, water quality monitoring, and treatment of polluted water bodies. The standardization of collection operations and the accuracy of the obtained data directly affect the normal development of follow-up work. [0003] In a water body, the difference in water depth will lead to the difference in the properties of each layer of water body. In the same water body, physical properties such as light intensity, water temperature, and transparency are different at different water depths; biochemical indicators such as dissolved oxygen content, microbial quantity and type, and dissolved organic matter types are also different; in pollute...

Problems solved by technology

Fu Huifang and others once invented a water sample collection device (patent authorization number: CN202599716 U). This device has the functions of fixed depth and layered sampling. However, the position of the water collection container on the connecting pipe is fixed and cannot be set according to actual needs. The depth of the water collection container is fixed; and in this device, each water collection container is connected by a hollow connecting pipe and communicates with each other, and the water samples in the container are easy to mix; moreover, because the connecting pipe is a hard pipe and cannot shrink, Inconvenient to carry

Using this device to collect water samples not only cannot set the position of the water collection container according to actual needs, but also the water samples in each water collection container are easily mixed.
