Abstract

The invention discloses a wireless charging device and system for an autonomous underwater vehicle, and a coil winding method. The wireless charging device is a magnetic coupling structure including atransmitting end and a receiving end; the transmitting end is provided with a C-type transmitting magnetic core on which a transmitting coil is wound, and the receiving end has an arc surface I-typereceiving magnetic core on which a receiving coil is wound; an open end of the C-type transmitting magnetic core forms an arc cylinder surface, the arc cylinder surface is matched with an arc outer surface of the autonomous underwater vehicle, and an outer arc face of the arc surface I-type receiving magnetic core is matched with the arc inner surface of the autonomous underwater vehicle. The method includes: a step of determining wire spacing of the receiving wire coils according to the number of effective turns at the receiving end and effective length of the arc surface I-type receiving magnetic core; according to the wire spacing, the receiving wire coil is wound on the receiving end. Via the wireless charging device and system and the coil winding method, coupling between a transmitting end and a receiving end, which are misplaced, in a wireless charging device for a conventional autonomous underwater vehicle can be improved.

Description

technical field [0001] The present invention relates to the technical field of wireless charging and underwater vehicles, in particular to a wireless charging device, system and coil winding method for autonomous underwater vehicles. Background technique [0002] Autonomous underwater vehicle AUV (Autonomous Underwater Vehicle) has the advantages of high flexibility, automatic control, and high concealment, and has been widely used in the fields of marine resource exploration and seabed terrain survey. However, due to the limitations of AUV's own size and battery capacity, its load capacity and battery life are poor. Wireless charging technology can realize the charging method that AUV is completely isolated from the external environment, avoiding hidden dangers such as short circuit and electric spark, high reliability, low maintenance cost, and can complete power supply safely, reliably and efficiently.

Problems solved by technology

[0003] Some wireless charging devices used to charge AUVs in the prior art are installed at the bottom of the AUV to avoid electromagnetic interference to internal equipment, which requires changing the shape of the AUV and charging When using AUV, it is necessary to accurately locate the center position of the transmitter; there are also some wireless charging devices that do not need to change the shape, but are highly sensitive to misalignment, and have a greater impact on non-aligned charging, and the heavier magnetic core increases the weight of the AUV itself; In addition, some wireless charging devices use planar coils, which are less sensitive to misalignment. However, the magnetic coupling structure of the planar coil has large magnetic leakage on the back, and the problem of electromagnetic radiation is serious. It is necessary to install a shielding layer and occupy a large space in the AUV battery compartment.

[0004]Based on this, how to improve the power transmission effect of the existing wireless charging device to the AUV and reduce the power transmission effect of the existing wireless charging device on the basis of avoiding electromagnetic interference to the internal equipment of the AUV. Volume, improve dislocation coupling, no effective solution is given in the prior art
