Description
Technical Field
The present invention relates to the field of wireless power transmission technologies, and in particular, to a rotating wireless power transmission assembly and an apparatus.
Background
In production life practice, we often apply a stable voltage to the rotating mechanism. Mercury slip rings are one of the common devices that can apply a voltage to a rotating mechanism. The mercury slip ring is a conductive rotary joint using mercury as a fluid medium, and is an industrial part. The most different point from the traditional carbon brush slip ring is that the fixed end and the rotating end are integrated together by mainly using liquid mercury as a conductive medium, and the carbon brush is not needed to be used for conducting and transmitting electricity during rotation, but the mercury is directly used for conducting and transmitting electricity.
However, mercury itself is a toxic substance, and although mercury in the mercury slip ring is sealed, there is still a small amount of leakage. Adversely affecting production and environment. At the same time, the shaft generates a certain amount of wear during rotation, which is usually very small in volume. Adversely affecting industries such as electroplating. Meanwhile, due to strict sealing requirements, the mercury slip ring has high process precision requirements and high selling price.
Therefore, it is desirable to design a contactless, environmental pollution-free rotating wireless power transmission assembly and device.
