Conical anti-overflow water sample collection barrel

The invention discloses a conical anti-overflow water sample collection barrel. The conical anti-overflow water sample collection barrel comprises an upper lifting rope, a conical barrel body, a lowerlifting rope and an anti-overflow percolation body; the upper lifting rope penetrates through and is fixed around the outer side of the upper bottom surface of the conical barrel body, the lower lifting rope penetrates through and is fixed around the outer side of the lower top surface of the conical barrel body, a through hole with internal threads is formed in the middle of the lower top surface of the conical barrel body, and the spill-proof percolation body is screwed in the through hole with internal threads in the middle of the lower top surface of the conical barrel body. According tothe invention, a water sample in a natural water body can be rapidly and efficiently collected, the phenomenon that the water sample collection barrel overflows after being filled with the water bodyis effectively prevented, t
