[0002] In the field of marine geological exploration, on-site sediment sampling is the basic work of sediment analysis. The existing sediment samplers mainly include gravity type and excavation type, etc., each sampling volume is large, and it is suitable for soft soils that can provide large sampling depths. Soil, the sampling effect of the harder sediment bed that requires shallow surface sampling is not ideal; moreover, the sand dredging device on the existing sampling device has poor wear resistance and corrosion resistance, and has a short service life

Abstract
The invention discloses a seabed sediment sampling device for marine engineering, which comprises a sampling container. The sampling container is composed of two arc-shaped side plates and an arc-shaped bottom plate. The two side plates are welded to the arc-shaped bottom plate. There is a groove, the front end of the arc-shaped bottom plate is equipped with a sand dredging assembly, the groove is equipped with a water outlet, the upper end of the sampling container is equipped with a pin shaft, and the pin shaft is connected to the external cable. For collection, the dredging components adopted have good wear resistance, corrosion resistance, and long service life; in addition, the excavated sand will not be lost, and the sand dredging efficiency is high.
Description
technical field [0001] The invention relates to the technical field of sediment sampling, in particular to a seabed sediment sampling device for marine engineering. Background technique [0002] In the field of marine geological exploration, on-site sediment sampling is the basic work of sediment analysis. The existing sediment samplers mainly include gravity type and excavation type, etc., each sampling volume is large, and it is suitable for soft soils that can provide large sampling depths. Soil, the sampling effect of the harder sediment bed that requires shallow surface sampling is not ideal; and the sand dredging device on the existing sampling device has poor wear resistance and corrosion resistance, and has a short service life. Contents of the invention [0003] The object of the present invention is to provide a seabed sediment sampling device for marine engineering, to solve the problems raised in the above-mentioned background technology. [0004] In order to ...
