Problems solved by technology

However, the radius of the coil cannot be increased without limit, so there is a contradiction between increasing the transmission distance and reducing the volume of the system
[0006] (2) Unstable power transmission
Different from the wireless charging system on land, due to the influence of the water flow, the relative position and distance between the transmitting coil and the receiving coil are changing in real time, and even relative rotation will occur. Therefore, the coil structure of the wireless charging system on land is not suitable for underwater Next wireless charging

Abstract

The invention discloses a coupling coil and magnetic core structure used for underwater wireless charging and an underwater wireless charging system. The coupling coil and magnetic core structure comprises a transmitting end and a receiving end. The transmitting end and receiving end comprise annular-shaped magnetic core skeletons and coils disposed on the skeletons in a coiled manner. The transmitting end coil and the receiving end coil are in an embedded arrangement, and a certain gap is arranged therebetween, and the transmitting end coil and the receiving end coil are coupled with each other, and a coupling magnetic field is in a radial direction. The transmitting end coil and the receiving end coil are coupled with each other by the radial magnetic field, and an object of realizing wireless electric energy transmission is achieved.

Description

technical field [0001] The invention relates to a coupling coil and magnetic core structure and system applied to underwater wireless charging. Background technique [0002] The exploration and scientific research activities in the sea are inseparable from the support of underwater electromechanical equipment. As a main power supply method for underwater electromechanical equipment, the power battery pack has the characteristics of stable voltage, reliable power supply, and flexible loading and unloading; however, it needs to be recharged when the battery pack is exhausted. Traditionally, a conductor-contact wet-swap power interface is used to connect underwater equipment to a power source for charging. Although this power transmission interface technology is relatively mature and can be used for a long time on the seabed after one plug and unplug, it is difficult to support future high-density and high-intensity marine scientific research for a long time due to factors suc...
