Problems solved by technology

[0003] In the process of lowering the water collector, in order to determine whether the water collector has been lowered to the above-mentioned predetermined water collection depth, it is generally confirmed by pulling the mark on the rope of the water collector, and the actual depth of the water collector in the water body is determined by the water. There is often a large error due to the influence of the flow rate

Abstract

The invention discloses a fixed-depth water sample collection device, which comprises: a base body having a water collection chamber, wherein the upper end and the lower end of the water collection chamber are respectively provided with a one-way valve and a water inlet hole, and the one-way valve allows a water sample in the water collection chamber to flow out in a one-way manner; a sealing mechanism which is fixed to the base body and comprises a plugging piece capable of moving towards the water inlet hole to seal the water inlet hole; and a pressure sensor which is arranged at the bottomof the base body and is electrically connected with the sealing mechanism; the gravity center of the base body is located below the water inlet hole. According to the fixed-depth water sample collection device, it is guaranteed that water in the water collection chamber is a water sample with the preset depth, an existing mode of judging the sampling depth through a rope and the like is abandoned,the water collection efficiency in water environment investigation is improved, the depth precision of water sample collection is improved to a large extent, and the water collection cost is reduced.

Description

technical field [0001] The invention relates to the field of water quality monitoring, in particular to a depth-fixed water sample collection device. Background technique [0002] Water samples are an important judgment basis for water quality monitoring. In order to obtain water samples, spherical water collectors are usually used. When the spherical cover type water collector is lowered for sampling, the two spherical covers are opened, and after reaching the predetermined water collection depth, the hammer is released to make the two spherical covers close for sampling. [0003] In the process of lowering the water collector, in order to determine whether the water collector has been lowered to the above-mentioned predetermined water collection depth, it is generally confirmed by pulling the mark on the rope of the water collector, and the actual depth of the water collector in the water body is determined by the water. There is often a large error due to the influence o...
