Mechanical layered liquid sampling device

Abstract

The invention relates to an experimental sampling device, and more specifically relates to a mechanical layered liquid sampling device. The mechanical layered liquid sampling device comprises a barrel body and a plurality of sample storage devices; the sample storage devices are uniformly arranged along the axis direction of the barrel body; the outer wall of the barrel body is provided with sample sampling and storing ports in one-to-one correspondence to the sample storage devices; the outer side of the barrel body is provided with a connecting plate along the axis direction; the upper end of the connecting plate is connected with the upper end of the barrel body via a sampling switch; the lower end of the connecting plate is connected with the lower end of the barrel via a balance spring; the connecting plate is provided with a plurality of sealing plugs in one-to-one correspondence to the sample sampling and storing ports along the axis direction of the barrel body. According to the mechanical layered liquid sampling device, the plurality of the sample storage devices are arranged in the barrel body, so that simultaneous sampling of samples at different depth can be realized; the outer side of the barrel body is provided with the connecting plate, and the connecting plate is provided with the sealing plugs in one-to-one correspondence to the sample sampling and storing ports, so that sample sealed storage can be realized; and the mechanical layered liquid sampling device is provided with the sampling switch to control opening and closing of the sealing plugs, so that sample sampling and storing are more convenient.

Description

technical field [0001] The invention relates to an experimental sampling device, in particular to a mechanical layered liquid sampler. Background technique [0002] In the laboratory, the sampler is a commonly used experimental instrument. The traditional liquid sampler uses an open container to directly sample from the sample pool, and then draws the sample from the sampler with a straw for experimentation. This kind of sampler mainly has the following disadvantages: the sampler can only perform sampling at one depth usually, and cannot sample and analyze samples at different depths, and it is also extremely inconvenient when sampling corrosive liquids. Contents of the invention [0003] In order to solve the above problems, the present invention provides a mechanical stratified liquid sampler with reasonable structure and simple and convenient operation, which can realize the sampling of depth samples without liquid. [0004] The technical solution adopted in the prese...
