Intelligent ship base deep-sea sediment gravity sampling device

Abstract

The invention discloses an intelligent gravity sampling device for ship-based deep-sea sediments, which belongs to the technical field of underwater sediment sample collection in geotechnical, geological, biological and environmental engineering. The intelligent gravity sampling device includes two parts: a gravity sampling system and a real-time data acquisition, analysis and processing system. The invention is suitable for collecting deep sea sediments, and can evaluate and improve sampling quality and efficiency. The present invention adopts the integrated self-capacitance sensor, which can reduce the size of the sensor and the sealed shell of the sensor, and ensure the stability and reliability of the collected data. The sensor data transmission mode adopts wireless bluetooth, which can improve the efficiency of data export; supporting data processing software The data can be analyzed in real time and quickly, and the evaluation of the sampling quality can be given; the computer software numerical simulation optimization system can be used to optimize the design of the gravity sampler and the shroud in real time, thereby improving the sampling quality and efficiency.

Description

technical field [0001] The invention belongs to the technical field of underwater sediment sample collection in geotechnical, geological, biological and environmental engineering, and relates to a ship-based deep-sea sediment intelligent gravity sampling device. Background technique [0002] With the construction of my country's "Belt and Road" and "Maritime Silk Road", it has become the requirement of the development of the times to continuously march to the sea. Seabed sediments, especially deep-sea sediments, are very important for the evaluation of foundation soil strength and stability in geotechnical engineering, the division of sedimentary ages in geological engineering, the study of benthic organisms in bioengineering and the analysis of pollutants in environmental engineering . At present, the effective way to collect deep sediments on the seabed surface is mainly a gravity columnar sampler, which mainly relies on the gravity of the sampler itself to plunge the cyl...

Problems solved by technology

[0004] The purpose of the present invention is to solve the key problems such as the inability to monitor the falling track and attitude of the traditional gravity sampler in the water, and the inability to evaluate the sampling quality of sediments. The sensor system is installed on the gravity sampler to record the time-space position, acceleration, deflection angle, seawater temperature, salinity and other information of the sampler, and combined with Acoustic Doppler Current Profilers (ADCP) to measure the ocean current Analyze and evaluate the drop attitude and sampling quality of the sampler in the water as the speed changes with the water depth
