Conical anti-overflow water sample collection barrel

The conical spill-proof water sample collecting barrel comprises an upper lifting rope, a conical barrel body, a lower lifting rope and a spill-proof percolation body, the upper lifting rope is fixedto the periphery of the outer side of the upper bottom face of the conical barrel body in a penetrating mode, the lower lifting rope is fixed to the periphery of the outer side of the lower top face of the conical barrel body in a penetrating mode, and a through hole with internal threads is formed in the middle of the conical barrel body. And the anti-overflow percolation body is mounted in a through hole with an internal thread in the middle of the lower top surface of the conical barrel body in a threaded manner. The water sample collecting barrel can rapidly and efficiently collect water samples in natural water, the phenomenon that the water sample collecting barrel overflows after being filled with the water is effectively prevented, the problem that other impurities such as weeds and leaves float on the sur
