Abstract

The invention discloses a non-contact connecting device for transmitting underwater electric energy, which is composed of a socket and a plug, wherein electromagnetic induction coils are arranged in the socket and the plug, can be provided with a standard PM type magnetic core or a standard P type magnetic core and also can be provided with no magnetic cores; an inverter circuit in the socket converts direct current provided by an underwater base station into high-frequency alternating current to produce an alternating magnetic field with the same frequency; and a secondary coil in the socketproduces induced voltage which drives a load after passing through a received switching circuit in the plug. Compared with the traditional connector, the invention transmits electric energy between magnetic fields without direct contact between the plug and the socket, thus avoiding contact wear and greatly improving the reliability and the service life of equipment; in addition, the invention canalso avoid high expense caused by the fact that an underwater robot is used for plugging during underwater moist plugging of connectors.

Description

technical field [0001] The invention relates to a universal connection device for electric energy transmission in an underwater environment. Background technique [0002] Seawater is a good conductor of electricity, so the transmission of electric energy under water cannot be done in the same way as the transmission of electricity on land by exposed conductors. At present, wet-plug connectors that contain metal cables and transmit electrical energy through conductor contact are mostly used. However, such connectors are expensive and have a short service life, and require ROVs to perform complex plug-in operations, so their popularization and application are greatly limited. . With the improvement of electric energy and signal transmission technology, it becomes possible to supply electric energy, send instructions and receive data to underwater equipment through underwater base stations for a long time. For this reason, there is an urgent need for a connection device that i...
