Technical Field

Background
Conventional power transmission schemes have failed to meet the needs of certain specific applications. For example, in a wind power generation system, when a fan is driven to rotate by wind power, the blade of the wind power generation system often needs to be adjusted in posture, and energy required for driving the blade to rotate is often transmitted through a conductive slip ring. However, conductive slip rings suffer from a number of disadvantages: firstly, the conductive ring is worn, if the content of the lubricant is high, the wear amount is small, but the conductivity is poor; conversely, the lubricant content is small, the conductivity is good, but the abrasion loss is increased. Secondly, the heat generated at the contact part of the slip ring and the electric brush is larger, and the conduction ring is difficult to dissipate heat by conduction because the conduction ring channels are insulated and the insulating material is poor in heat conductivity.
Therefore, some attempts have been made to transmit electric energy to the rotating component by using a rolling ring technology, for example, the sliding friction is changed into rolling friction, the abrasion loss is reduced, but the problems that the stress of the rolling bodies is uneven, the grinding cannot be discharged and the like still exist; the mercury confluence ring technology is adopted, liquid metal is used for replacing sliding friction, friction is avoided, and sealing is difficult; the optical confluence ring technology is adopted, and the non-contact optical fiber is used as a transmission medium, but the power which can be transmitted is smaller.
