Marine geology measuring and sampling equipment

Abstract

The invention relates to marine geology measuring and sampling equipment. The equipment comprises a mounting plate mounted on a ship body and extending out of the ship body; a rotating disc is rotationally arranged on the mounting plate, a guide pipe chain is wound on the rotating disc, one end of the guide pipe chain is fixedly connected with the rotating disc, and the other end of the guide pipe chain extends into water and is connected with a sampling unit capable of sampling seabed sediments; the sampling unit can be communicated with the conduit chain; the guide pipe chain comprises a plurality of same guide pipe chain links, the adjacent guide pipe chain links are hinged, and the adjacent guide pipe chain links are connected through locking units at equal intervals; the first conduit chain link is fixedly connected to the turntable, and the last conduit chain link is provided with a sampling unit which can be communicated with the last conduit chain link. By arranging a plurality of same conduit chain links, the conduit chain links can be assembled into a rigid conduit chain through the locking units during sampling, the sampling unit is sent to the seabed for sampling, and a sampled object is sent to the sea surface through the conduit chain, so that sampling and collection can be quickly carried out.

Description

technical field [0001] The invention relates to the field of geological survey, in particular to a marine geological survey and sampling device. Background technique [0002] Sediment is an important part of oceans, rivers, lakes, reservoirs and other waters. It can exchange materials with the overlying water body through various channels. The living environment of benthic animals plays an important role. The "health" of sediments is undoubtedly related to the health of aquatic ecosystems, and then affects humans through the food chain. Therefore, it is of great significance to collect and monitor sediment samples . There are various kinds of sediment sampling devices at present, mainly including gravity sampler, piston sampler, connecting rod sampler, freezing sampler and drilling sampler, etc. Among them, the gravity sampler is divided into two types: grab type and columnar type. The grab type sampler has a simple structure and is easy to operate, but it disturbs the sed...

AI Technical Summary

Problems solved by technology

Among them, the gravity sampler is divided into two types: grab type and columnar type. The grab type sampler has a simple structure and is easy to operate, but it disturbs the sediment sample greatly and has poor sealing performance, which may easily cause problems such as sample loss and low collection efficiency; columnar type The sampler is inserted vertically into the sediment to obtain an undisturbed columnar sediment sample, and the obtained sample has a good representativeness

The existing sampling equipment cannot perform continuous sampling, and the sampling efficiency is low; the existing sampling equipment realizes the transportation of samples by moving the equipment to the sea surface after each sampling, and the sampling efficiency in the same area is low
