Compared with the prior art, the utility model has the following beneficial effects:

when the water sampling device is used, the pulling rope pulls the cylinder to descend, water samples enter the cylinder from the one-way valve of the water inlet in the descending process, and the water samples upwards rush out the cover plate through the water inlet, so that the water samples pass through the cylinder from bottom to top. When the cylinder body descends to the depth required by the water sample, the cylinder body stops descending, the traction rope starts to lift the cylinder body, the flip plate downwards covers the water passing port under the water pressure environment, and the water sample with the required depth collected in the cylinder body cannot flow downwards under the action of the one-way valve. The deep water sampler is added with a graduated sampling traction rope to clearly determine the sampling depth, a water outlet is added with a water outlet pipe and a water outlet valve, so that the water outlet amount can be conveniently controlled after sampling, and a water sample with the required depth collected in the barrel is discharged.

The utility model will be described in further detail with reference to the drawings and the detailed description.
