Problems solved by technology

However, due to the characteristics of the cylindrical shape of the AUV and the particularity of the seawater environment in which it is located, the transmission efficiency of the existing non-contact energy transmission magnetic field coupling device for the AUV is relatively low.

Abstract

The invention discloses a non-contact energy transmission structure and an underwater vehicle power supply system. The non-contact energy transmission structure includes at least one coupling unit, the coupling unit includes a primary unit and a secondary unit oppositely arranged, the primary unit includes a primary core and a primary core wound on the primary core A coil, the secondary unit includes a secondary iron core and a secondary coil wound on the secondary iron core, the primary iron core and the secondary iron core are arc-shaped. The non-contact energy transmission structure provided by the present invention can reduce the air gap to the greatest extent because it incorporates an iron core, and the ε-shaped iron core is arc-shaped. At the same time, the coupling units used symmetrically can ensure the alignment of the primary unit and the secondary unit due to the electromagnetic force of mutual attraction, which will increase the coupling coefficient, thereby improving the efficiency of non-contact power transmission.

Description

technical field [0001] The invention relates to the field of non-contact charging, in particular to a magnetic field coupling structure for non-contact energy transmission of an underwater unmanned vehicle and an underwater vehicle power supply system. Background technique [0002] As an important tool for exploring the underwater world, AUV (Autonomous underwater vehicle) has been widely used in civil and military fields. However, due to the limitation of its own size and battery capacity, AUV cannot work underwater for a long time. The existing energy transmission mostly uses wet plug connectors, and must be salvaged and recharged, and the detection range is limited; at the same time, it must be guaranteed The ship is assisted, so it cannot be unmanned, which reduces the work efficiency and concealment of AUV. [0003] The non-contact power transmission technology can make the AUV circuit system have a good isolation effect from the external environment, avoid the influen...
