Description
Technical Field
The invention relates to the technical field of wireless power transmission, in particular to a sleeve type wireless power transmission coupling mechanism.
Background
The traditional power transmission mode can not meet the requirements of some special application occasions. For example, in a wind power generation system, when a fan is driven to rotate by wind power, the blade of the fan 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, there are a number of disadvantages with conductive slip rings: firstly, the conducting ring is worn, if the content of the lubricant is high, the wearing capacity is small, but the conductivity is poor; on the contrary, the lubricant content is small, the conductivity is good, but the abrasion loss is increased. Secondly, the contact part of the slip ring and the electric brush generates heat greatly, and the heat dissipation of the conductive ring is difficult to realize through conduction because the conductive ring channel and the channel are required to be insulated, and the insulating material usually has poor heat conductivity.
Therefore, some new methods are tried to transmit electric energy to a rotating component, for example, a rolling ring technology is adopted, sliding friction is changed into rolling friction, the abrasion loss is reduced, but the problems that the stress of a rolling body is uneven, grinding cannot be discharged and the like still exist; the mercury slip ring technology is adopted, and sliding friction is replaced by liquid metal, so that no friction is caused, but sealing is difficult; the optical slip ring technology is adopted, and a non-contact optical fiber is used as a transmission medium, but the power capable of being transmitted is small. Thus, none of these techniques fully satisfies the need for long-life power transfer between rotating interfaces of moving parts.
In addition, in the conventional energy transmission mechanism, in order to realize the transmission of the control signal and the acquisition of the sensor signal, an additional communication module is often required to be added, and the installation structure is complex.
