A kind of underwater power station oriented to seabed geodetic coordinate datum

Abstract

The invention discloses an underwater power station facing the seabed geodetic coordinate reference, relates to the technical field of development and design of deep-sea equipment, includes a seat, and also includes an oil-immersed lithium battery module, a power supply control module and an acoustic communication module; the oil-immersed lithium The battery module includes a battery core, a casing and insulating oil; the battery core is arranged in a battery box whose inner cavity is filled with insulating oil, and a pressure compensator is used to perform pressure compensation on the battery box. The beneficial effect of the present invention is that, on the one hand, the system carries a voltage-resistant high-capacity battery, which can significantly increase the battery life of the seabed reference point; The offshore operation risk and error risk brought about by re-deployment and calibration can significantly improve the long-term service capability of the seabed geodetic datum, and reduce the operation and maintenance operation risk and operation cost of the seabed geodetic datum.

Description

technical field [0001] The invention relates to the technical field of deep sea equipment development and design, in particular to an underwater power station facing the seabed geodetic coordinate reference. Background technique [0002] The "China Ocean Development Report (2013)" pointed out: "In the next 20 years, China's ocean work will be based on resources and go beyond resources to expand the national strategic development space, increase the national strategic resource reserves, promote deep-sea technology to reach the world's leading level, and establish China's leading position in the world. The status of a powerful country in ocean affairs is a strategic goal". However, it can be seen that the implementation of this strategy has encountered severe challenges from internal technology and external environment, that is, the challenge of insufficient ability to quickly and even real-time obtain the exact location of information such as resources, events, and targets. ...

Problems solved by technology

In terms of network deployment scheme, Japan adopted the network deployment principle of land geodetic surveying, that is, firstly laying out I control network points, and then encrypting and forming II and III control networks on this basis, but how to adapt to the seabed environment and the characteristics of acoustic ranging There are few international literatures on the site selection, network structure and shape design that meet the positioning accuracy requirements; in the construction of the submarine geodetic control network, most countries in the world use the submarine geodetic reference measurement method combining GNSS and acoustic positioning technology. Among them, Japan has adopted the comprehensive observation technology of sea surface platform + GNSS + SBL + submarine Beacon + submarine cable, South Korea has adopted the measurement technology combining GNSS and underwater acoustic positioning (LBL + SBL), and the submarine network of the United States is only used for underwater navigation and monitoring. , the seabed control network survey adopts GNSS positioning technology. The above positioning technology is effective for solving the construction of a single seabed reference point, but it is time-consuming and laborious for the construction of a regional seabed reference network, which is not conducive to the long-term operation and maintenance of the seabed geodetic reference network.
