Preferably, the bottom of the sampling barrel is thicker than the side wall and is made of a material with high density. And the vertical state of the sampling barrel is kept when the sampling barrel sinks.

The working principle is as follows:

the utility model utilizes the principle that the buoyancy ball is subjected to buoyancy in water, when the buoyancy of the buoyancy ball is larger than the sum of the spring elasticity and the gravity of the cover plate, the cover plate is opened, a water sample can enter the sampling barrel, so as to complete water sample collection, and when the buoyancy ball is not subjected to buoyancy or has small buoyancy, the cover plate is kept closed, so that the water sample in the sampling barrel can be ensured not to be influenced by floaters or oil stains and the like on the surface of a sampling area; meanwhile, the sampling of water quality in different water depths can be realized by changing the length of the floating rod; after once sampling is accomplished, lift the buoyancy ball off, load onto the handle, rotate the handle and can wash the sampling bucket inner wall, cause cross contamination because of the remaining of the sample last time when avoiding the secondary sampling.

Since the technical scheme is used, the beneficial effects of the utility model are that:

the utility model can control the cover plate of the sampling device to open and close under the influence of the buoyancy borne by the buoyancy ball, thereby achieving the function of automatic sampling at a fixed depth; by changing the length of the floating rod, the water quality sample collection with different fixed depths can be realized.

The utility model discloses set up belt cleaning device under the apron, can wash the sampling bucket inner wall, avoid taking a sample many times and cause the cross contamination of sample.
