The testing scope is very wide, including unpolluted and polluted natural water (rivers, lakes, seas and groundwater) and various industrial drainage, etc.; since testing experiments cannot be carried out immediately after water sampling, the samples are usually stored in corresponding storage devices after sampling.

[0003] A Chinese patent discloses a water quality sampler for environmental monitoring (authorization announcement number CN216816100U). When the device is in use, the patented technology can sink the sampling bucket to the bottom of the water through a counterweight component, and at the same time control the air content in the sleeve through an inflation component to ensure that the sampling bucket is at an appropriate depth. Then, the driving component is used to control the two cover plates to move away from each other, so that the water inlet is exposed, thereby sampling water quality at different depths. However, it cannot obtain water samples of different volumes according to needs, and it is not convenient to observe the condition of the water samples. Utility Model Content
