At present, water research and observation of water quality and changes are realized through the collection, testing and analysis of water samples. Water sample collectors are commonly used water sample collection devices, but traditional water sample collectors do not have the ability to measure The function of water depth cannot be used to collect water samples at a fixed depth. At the same time, the existing water sample collector needs to be turned upside down to discharge water from the upper end in the process of transferring the collected water samples after sampling, resulting in water The sample transfer is easy to be mixed with gas, which will cause interference during certain index tests, and may also increase the risk of sample contamination during the process. Therefore, in addition, the existing water sample collectors usually require two or more people to cooperate at the same time. The labor force is greatly increased, the use is very inconvenient, and the structure is complicated and the volume is large, resulting in inconvenience to carry. How to design a water sample collector that can collect water samples at a fixed depth, is easy to carry, easy to use and has a simple structure has become a technical problem to be solved urgently by those skilled in the art.

Preferably, the interior of the telescopic lifting rod is a hollow structure, and the outer surface of the telescopic lifting rod is provided with scales.

Compared with the prior art, the beneficial effect of the utility model is: the water sample collector, through the scale provided on the outer surface of the telescopic lifting rod, can realize the measurement of the sampling depth while lowering or lifting the collector , by adjusting the size and thickness of the sealing rings at both ends of the piston, it can not only play a waterproof role, but also not cause too much friction between the sealing ring and the inner wall of the stainless steel cylinder. There is a piston lifting line in the middle of the side, lift the piston lifting line upward, the piston will move upward with the piston pulling line, and the pressure in the cylinder under the piston will decrease, so that the water sample is sucked into the cylinder from the water inlet, which is convenient The operator extracts the water sample, which greatly improves the labor efficiency of the inspector. The operation is simple. By pulling the piston cable down in the middle of the lower side of the piston, the water sample can be easily transferred out, avoiding the transfer of the water sample. The gas is mixed in the process, which will cause interference in the test of certain indicators. By installing a metal disc at the bottom of the cylinder, the metal disc is connected with the collection tube. The metal disc can increase the weight of the collector and keep it vertical in the water. , to increase the accuracy of measuring water depth, through the disc at the bottom of the collection tube, the operator can feel that the collector touches the bottom of the water body, reduce measurement errors, and prevent the collection tube from being inserted into the sludge at the bottom of the water body, causing the water inlet to be blocked. At the same time, impurities contained in the water sample can be filtered out through the filter screen provided on the water inlet hole of the collection tube, and the utility model has the characteristics of simple structure and convenient portability.
