The patent discloses a technical solution for convenient sampling, which solves the problem that in the process of performing multiple groups of sampling with existing water resource sampling devices, workers usually need to manually remove the test tubes that have stored the sampled water resources and then place the new test tubes that need to be stored at the bottom of the sampling device, which requires the test tubes to be disassembled and replaced, thereby delaying a certain amount of work efficiency.

The impurities enter the interior of the extraction pipe, easily covering the extraction pipe and clogging the water pump, reducing the extraction efficiency and use effect.
