The invention discloses a
seawater segmented sampling device which comprises a bottom plate,
inflatable gaskets, connecting seats, sampling bottles, a threaded rotating rod, a rotating gear ring, a top plate, a bearing, a sampling
bottle lifting control device, a hook, a connecting rod and a counterweight ball, the
inflatable gaskets are installed in the periphery of the bottom plate, and the three connecting seats are installed on the periphery of the top of the bottom plate at equal intervals; sampling bottles are mounted in the connecting seats, threaded rotating rods are mounted in the tops of the sampling bottles, rotating gear rings are mounted on the threaded rotating rods, the tops of the threaded rotating rods are mounted on a top plate through bearings, and a sampling
bottle lifting control device is mounted between the top of the bottom plate and the bottom of the top plate; a hook is installed in the center of the top of the top plate, a connecting rod is installed in the center of the bottom of the bottom plate, and a counterweight ball is installed at the bottom of the connecting rod. The
seawater sampling device is reasonable in design,
seawater at the same position can be sampled in different time periods, and seawater samples at different time periods can be obtained while the throwing frequency can be effectively reduced.
