Problems solved by technology

However, limited by the size and load capacity of autonomous underwater vehicles, the battery capacity is limited, and the battery life problem has always limited the further development of autonomous underwater vehicles.
In recent years, there have been some magnetic coupling devices used in wireless charging of autonomous underwater vehicles, but most of these magnetic coupling devices are single-phase magnetic coupling devices with low power levels; in addition, the input side current of single-phase wireless charging systems The ripple is large, and the large ripple will reduce the life of the battery in the charging dock

Abstract

The invention discloses a magnetic coupling structure for wireless charging of an autonomous underwater vehicle and an autonomous underwater vehicle system, the magnetic coupling structure comprises atransmitting end arranged on a charging dock and a receiving end arranged on an autonomous underwater vehicle. The receiving end includes a receiving coil disposed along a radial direction of the autonomous underwater vehicle, including an inner end portion located at a radial center position of the autonomous underwater vehicle, an outer end portion located at an inner surface of the autonomousunderwater vehicle housing, and an intermediate portion located between the inner end portion and the outer end portion. The magnetic coupling structure for wireless charging of the autonomous underwater vehicle provided by the invention solves the problems of poor endurance and difficult charging of the autonomous underwater vehicle. The input side current ripple of the magnetic coupling structure is small, the transferable power level is large, and the battery life can be prolonged.

Description

technical field [0001] The invention relates to the technical field of wireless charging, in particular to a magnetic coupling structure for wireless charging of an autonomous underwater vehicle and an autonomous underwater vehicle system. Background technique [0002] As an important sea force, autonomous underwater vehicles are important tools for marine geological and landform exploration, marine environment observation, and marine resource exploration. strength. However, limited by the volume and load capacity of autonomous underwater vehicles, the capacity of batteries carried is limited, and the battery life problem has always limited the further development of autonomous underwater vehicles. At present, wireless charging technology is an ideal means to solve the endurance problem of autonomous underwater vehicles and achieve the goal of unattended. [0003] Unattended underwater autonomous vehicles will be equipped with one or more charging docks underwater. For ch...
