[0025] When the utility model is in use: The barrel body 8 serves as the main structure of the entire sampler, bearing the stability and durability of the entire device. A water pump 21 is fixedly connected to the outer wall of the barrel body 8, which is one of the core components of the entire sampler. The water pump 21 is responsible for pumping water samples from various depths into the barrel body 8 to ensure the continuity and integrity of sampling. At the same time, the water pump 21 also serves as the power source for cleaning the device.
