Problems solved by technology

At present, wet-plug connectors that contain metal cables inside and transmit electrical energy and electrical signals through conductor contact are mostly used. However, such connectors are expensive and have a short service life, and require ROV to perform complex plug-in operations, so their promotion and application are limited. very restrictive

Abstract

The invention discloses a non-contact connecting device for transmitting underwater electric energy and signal, comprising a socket and a plug. Unidirectional electric energy transmission from the socket to the plug can be realized by the law of electromagnetic induction; bidirectional signal transmission between the socket and the plug can be realized by the optical communication principle. Compared with the traditional electric energy and signal transmission connection device, the invention does not need direct contact between the socket and the plug, so that the socket and the plug can realize respectively independent full packaging, and inner devices are separated from ambient environment, thus greatly simplifying sealing, effectively preventing water seepage and electricity leakage accidents, and creating favourable conditions for long-term stable operation of underwater electromechanical equipment; in addition, the invention can 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 non-contact connection device for electric energy and signal transmission in an underwater environment. Background technique [0002] Seawater is a good conductor of electricity, so no matter whether it is transmitting electric energy or electric signals underwater, it cannot use the exposed conductor contact method like transmitting electricity on land. At present, wet-plug connectors that contain metal cables inside and transmit electrical energy and electrical signals through conductor contact are mostly used. However, such connectors are expensive and have a short service life, and require ROV to perform complex plug-in operations, so their promotion and application are limited. Very restrictive. 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 ti...
