The water sampling device comprises a bucket for collecting water samples on the sea surface, a Nansen water sampler, a multi-bottle (or multi-bag) water sampler, a ball cover water sampler and the like for collecting water samples on each layer below the sea surface. In addition, the device also comprises a marine microorganism water sampler. The nan sen water sampler is a conventionally used water sampling tool. In order to meet the requirements of sampling work of ocean chemistry and the like, a plastic liner or full plastic Nansen water sampler is produced on the basis of the sampling work. The multi-bottle (or multi-bag) water sampler is characterized in that a plurality of water sampling bottles (or water sampling bags) are radially arranged on a hanger, and the water sampler is controlled to be opened and closed in a mode of using a hammer, a pressure switch element, a cable and the like, so that the multi-bottle (or multi-bag) water sampler is suitable for collecting water samples at different depths. The temperature and depth sensor can be used for independently collecting water, can also be used together with a temperature and depth or temperature and salt depth sensor, and collects water samples with required depth while measuring temperature and depth or temperature, salinity and depth. The ball cover type water sampler (also called Vandoen water sampler) is composed of a water sampling cylinder, a ball cover, a releaser, a fixing frame, a steel wire rope groove, a driving hammer and the like. When the water sampler is lowered down, the two ball covers are opened, and after the water sampler reaches the preset water sampling depth, the hammer is released to close the two ball covers for sampling.
