Underwater platform for exploration sampling or in-situ test and using method thereof

Abstract

The invention discloses an underwater platform for exploration sampling or in-situ test and a using method thereof. The underwater platform comprises a platform main body, a plurality of adjustable outriggers, a data acquisition module, a control module and a communication module, wherein the platform main body comprises a working face which is used for mounting underwater exploration sampling equipment or in-situ test equipment; the adjustable outriggers are mounted around the platform main body; the data acquisition module comprises a dip angle sensor which is used for measuring dip angle, relative to the horizontal plane, of the working face and a pressure sensor which is used for measuring pressure values of the adjustable outriggers; the control module is connected with each of the data acquisition module and the adjustable outriggers, and is used for receiving signals of the dip angle sensor and the pressure sensor and adjusting the lengths of the adjustable outriggers so as to make the working face of the platform main body keep horizontal; and through the communication module, the control module communicates with an upper computer. The underwater platform disclosed by the invention has a self-adaptive intelligent leveling function, is adapted to exploration work of complicated seabed surfaces, and is capable of obtaining real and reliable underwater stratum parameters.

Description

technical field [0001] The invention relates to an underwater exploration platform and its use method, which can ensure the normal progress of geotechnical engineering exploration sampling or in-situ testing in offshore waters, in particular, it belongs to an offshore engineering seabed exploration platform and its use method. Background technique [0002] In recent years, with the construction of a series of offshore projects such as cross-sea bridges, offshore wind power, deep-water ports, artificial islands and reefs, and submarine tunnels, and the implementation of the national "One Belt, One Road" strategy, my country's water transportation survey operations have extended from coastal and nearshore to High seas, exclusive economic zones, Asia, Africa, and Latin American port waters. Offshore engineering survey mainly involves drilling core sampling and in-situ testing. The existing seabed sampling and in-situ testing mainly rely on sampling by drilling rigs on ship-borne...

AI Technical Summary

Problems solved by technology

However, there are single functions and insufficient drilling depth, which makes it difficult to solve the problem of base tilt caused by the high-speed rotation of the underwater drilling rig, which affects the normal operation of the measurement and control equipment

[0005] To sum up, the existing equipment and methods have the weakness of strong pertinence and single function, and it is difficult to solve the problem of gradual inclination of the equipment base during sampling on the complex seabed or in-situ testing.

If the inclination is mild, the underwater exploration path will deviate, affecting the authenticity and reliability of the collected stratigraphic data; Equipment overturning accidents, a problem that limits the application of existing technologies in underwater surveys for offshore engineering
