Title:
ANNULAR HYBRID POWER GENERATION UNIT, PREPARATION METHOD THEREFOR, AND WAVE ENERGY POWER GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/216698
Kind Code:
A1
Abstract:
The present invention relates to the field of new energy power generation, in particular to an annular hybrid power generation unit, a preparation method therefor, and a wave power generation device. The hybrid power generation unit comprises a housing, coils, a friction electrode, friction balls and movable magnets. The housing comprises an annular sealing pipe cavity, The coils are arranged at intervals in the extending direction of the pipe cavity. The friction electrode is adhered to the inner wall of the pipe cavity. The friction balls are located in the pipe cavity. Each friction ball comprises a ball core and a sheath layer. The sheath layer is prepared from a friction power generation material having a polarity opposite to that of the friction electrode or an electron capture capability different from that of the friction electrode. Each movable magnet comprises a permanent magnet and a movable support. The movable supports abut against the inner wall of the pipe cavity. Each permanent magnet is fixedly connected to each movable support. The hybrid power generation unit can utilize electromagnetic induction power generation and friction motion power generation at the same time. The present invention solves the problems of low energy conversion rate, low power generation power, short service life, limited application scenarios of existing nano friction power generation devices.
