Deep sea non-contact type electric energy transmission coupler

Abstract

The invention discloses a non-contact electric energy transmission coupler in a deep ocean. The coupler comprises an upper moving magnetic core mechanism, a lower fixed magnetic core mechanism and a clamping releasing mechanism which are on a coaxial-line device. The upper moving magnetic core mechanism is provided with a first ferrite core, the lower fixed magnetic core mechanism is provided with a second ferrite core; a primary winding and a secondary winding are arranged in the first ferrite core and the second ferrite core respectively, and the relative position of the primary winding and the secondary winding is fixed by the clamping releasing mechanism in the charging process of the coupler, thus forming electromagnetic coupling to cause the electric energy to be transmitted to electric equipment; after the charging is finished, the primary winding and the secondary winding are separated, and the electric equipment can move freely. The invention can realize the electric energy transmission under water, thereby avoiding physical contact and electrical connection of interfaces of electricity transmission; fluid sealant is adopted to encapsulate and separate, thus avoiding marine corrosion and electric leakage. As the coupler has no cavity, high pressure in the deep ocean can be borne. The coupler has simple structure, is pressure resistant, has good tightness and high reliability and can effectively solve the defects of bad security of the interfaces of electricity transmission in the deep ocean and high cost.

Description

technical field [0001] The invention relates to a deep-sea non-contact electric energy transmission coupler applied in a high-pressure seawater environment. Background technique [0002] Underwater mobile devices are usually driven by electric energy. However, seawater is a good conductor of electricity. Underwater power transmission cannot use exposed conductor contact like land power transmission. At present, wet-plug joints are widely used, but the price of such joints is as high as more than 100,000 yuan, so its popularization and application are also greatly restricted. Contents of the invention [0003] The object of the present invention is to propose a deep-sea non-contact power transmission coupler suitable for deep-sea seawater environment application as an underwater power transmission interface. [0004] The deep-sea non-contact power transmission coupler of the present invention includes an upper moving magnetic core mechanism, a lower fixed magnetic core mec...

Problems solved by technology

[0002] Underwater mobile devices are usually driven by electric energy. However, seawater is a good conductor of electricity. Underwater power transmission cannot use exposed conductor contact like land power transmission.

At present, more methods are used for wet plugging joints, but the price of such joints is as high as more than 100,000 yuan, so its popularization and application are also greatly restricted.
