Portable static sediment sampler

The utility model relates to the technical field of water body sediment collecting devices. The structure comprises a fluid sediment collecting cavity (16), a solid sediment collecting cavity (17), a water discharging cavity (18) and a connecting rod (19), wherein the fluid sediment collecting cavity (16) mainly comprises a fluid sediment cavity body (1) and a one-way hinge (2); the solid sediment collecting cavity (17) consists of a solid sediment cavity body (3) and a cavity core (4) which are arranged coaxially; and the water discharging cavity (18) mainly comprises a water discharging cavity body (9), a bottom surface (7) of the water discharging cavity is provided with a water discharging hole (14) and the upper surface thereof is provided with a rubber movable cover (13). The portable static sediment sampler can prevent the fluid sediments from losing and also can prevent water from interfering samples by virtue of the one-way hinge and the rubber piston; and the solid sediments are collected in a transparent cavity core, not only the state of the sediments can be intuitively observed, but also the space distribution of the sediments can not be damaged, and the sampler is flexible and accurate and has the characteristics of portability, flexibility and simple operation.
