Sampling device for water quality detection

Abstract

The invention discloses a sampling device for water quality detection, belongs to the technical field of water quality sampling, and aims to solve the problems that sampling operation at different depths is inconvenient to carry out at the same position at present, and water at other depths cannot be prevented from entering a sampling pipe, the sampling device comprises a control end, and the bottom end of the control end is connected with a water depth adjusting structure; the number of the sample storage tubes can be added according to needs, so that the whole device can store more samples separately, the water depth adjusting structure is adjusted, the whole device can reach positions with different depths in water, and meanwhile, the arrangement of the multiple sample storage tubes is combined, so that the sample storage efficiency is improved. According to the sampling device, the connecting pipe is arranged in the sample storage pipe, so that sampling operation at different depths of the same position is facilitated in sequence, and the connecting pipe is sealed through the sealing structure, so that the connecting pipe is opened after reaching a specified depth, and water at other depths can be effectively prevented from entering the sample storage pipe.
