Embodiment 1

[0054] Based on the problems existing in the existing technology, the embodiment of the present invention proposes an underwater wireless charging method, so that underwater equipment such as AUV can be intelligently connected to the underwater docking station when the power is insufficient. Energy supply.

[0055] This embodiment provides a processing flow of a magnetic resonance-based underwater wireless charging method as follows: figure 1 As shown, the following processing steps are included:

[0056] Step S110, setting up an underwater docking station for charging the underwater equipment underwater.

[0057] An underwater docking station for charging underwater equipment is set underwater, and a communication circuit, a power supply, a rectifier circuit, a series resonant circuit, a resonant body, and a power amplifier are installed in the underwater docking station, and the underwater equipment is installed Communication circuit, battery, rectifier circuit, series res...

Embodiment 2

[0078] This embodiment provides an underwater wireless charging device based on magnetic resonance, its specific structure is as follows Figure 4 As shown, including: underwater docking station 1 and underwater equipment 2;

[0079] The underwater docking station 1 is configured to be installed underwater. After the underwater equipment to be charged is close to the underwater docking station, the resonant circuit in the underwater docking station converts electric energy into electromagnetic waves , the electromagnetic wave is transmitted to the resonator in the underwater docking station through electromagnetic coupling; the resonator in the underwater docking station and the resonator in the underwater equipment generate magnetic resonance, and the underwater The resonator in the lower docking station transmits the electromagnetic waves to the resonator in the underwater equipment;

[0080] The underwater equipment 2 is used to transmit the electromagnetic waves transmitt...

Abstract

An embodiment of the invention provides an underwater wireless charging method and apparatus based on magnetic resonance. In the method, a resonant circuit in an underwater transferring station converts electric power into an electromagnetic wave, a resonant body in the underwater transferring station transmits the electromagnetic wave to a resonant body in an underwater device, a resonant circuit in the underwater device converts the electromagnetic wave into electric power, and the electric power is used for charging a batter of the underwater device. According to an embodiment of the invention, by application of magnetic resonance energy transmission technology to underwater, underwater devices such as an AUV can be effectively charged underwater; and as for actual needs for AUV submarine operation, a traditional land-based artificial charging method can be effectively replaced, and the flexibility of the AUV without cables can be better highlighted. The underwater devices such as the AUV can be allowed to get rid of a load of a large battery pack, reduction in the weight and size of a charging battery is facilitated, lightweight and miniaturized underwater devices such as the AUV become possible, and the underwater devices such as the AUV are enabled to be more diversified and customized on demand for different environments.

Description

technical field [0001] The invention relates to the technical field of underwater wireless power transmission, in particular to a magnetic resonance-based underwater wireless charging method and device. Background technique [0002] The total area of ​​the ocean is 3.6×108 square kilometers, accounting for 70.8% of the total area of ​​the earth. In this vast and rich ocean space, there are rich marine biological resources, ocean energy, ocean thermal energy and marine mineral resources. With the progress of industrialization and urbanization, the resources available on land are becoming less and less, and people are gradually paying attention to the effective use of marine resources. It can be said that the 21st century is the century when human beings march into the ocean. As an important means of exploring the ocean, even the only means in some cases, the role of underwater robots in the development and utilization of the ocean is no less than that of rockets and space shu...
