Problems solved by technology

[0005] If the above two wireless energy transmission methods are used to wirelessly charge the AUV, there are the following disadvantages: Although the microwave wireless energy transmission technology has the longest transmission distance, the largest transmission power, and can overcome the influence of obstacles, the electromagnetic wave is severely attenuated in water, resulting in The energy loss is large, and the transmission efficiency is the lowest
Although the transmission power of the inductive coupling method can reach hundreds of kilowatts, and small-scale obstacles will not have a great impact on its power transmission, the disadvantage is that the requirements for transmission distance and transmission stability are too high, and it is difficult to apply to complex and multi-dimensional systems. Under the changing seabed natural environment

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...
