Sediment sampling device for ocean engineering

Abstract

The invention discloses a sediment sampling device for ocean engineering, and relates to the technical field of sediment sampling devices, the sediment sampling device comprises a device rack, the side wall of the device rack is connected with a plurality of winding drum supports, and the winding drum supports are provided with sampling device hanging coil assemblies used for sampling and collecting samples; and a swing reducing unit capable of reducing the sampling swing is mounted on the sampling device lifting coil assembly. According to the automatic sediment sampling device for the deep sea area, unwinding is conducted by rotating the hoisting and winding rotating wheel, the sediment sampling barrel is lowered to the seabed, then automatic drilling and sampling sealing are conducted through the sediment sampling barrel, and therefore the automatic sediment sampling work of the deep sea area is completed; the influence of underwater water flow on the lifting coil assembly of the sampling device is reduced, so that the sampling position is more accurate, and the position of a sample in the seabed can be judged, thereby facilitating accurate sampling.

Description

Technical field [0001] The present invention relates to the technical field of sediment sampling devices, and in particular, to a sediment sampling device for marine engineering. Background technique [0002] The marine project refers to the purpose of development, use, protection, and restoring marine resources, and the engineering subject is located on the new construction, reconstruction, expansion project of the coastline to the sea side, and is generally divided into two parts: the technical development technology and equipment facilities technology, in the ocean. Prior to construction of engineering construction facilities, the water body, sediment, and biology of the surrounding sea often need to be sampled to explore the impact of the speculation on the environment of the surrounding sea. [0003] The existing ways of sampling of sediments in the sea are manually sampling, requiring relevant personnel undergoing sampling, this way is inconvenient, easy to happen, and use ...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing sampling methods for sea area sediment are manual sampling, which requires relevant personnel to dive in for sampling. The sampling process in this way is cumbersome and inconvenient, and is prone to danger. , due to the flow of underwater water, the suspension rope will be inclined, resulting in the uncertainty of the seabed sampling position, and it is impossible to determine where the sample is located on the seabed. Therefore, in order to solve the above problems, this application proposes a marine engineering. Sediment Sampling Device
