The invention discloses an array type magnetic liquid kinetic energy collector based on coil suspension, which comprises a shell internally provided with a sealing cavity, and the sealing cavity is internally provided with a kinetic energy collecting unit and a friction electricity assembly. The kinetic energy collecting unit comprises a mass block, a permanent magnet fixed in the sealing cavity, magnetic liquid filled between the mass block and the permanent magnet and a corrugated pipe connected with the shell and the mass block, two opposite cavities are formed in the two sides of the mass block in the first direction, and at least part of the permanent magnet is located in the cavities; the corrugated pipe is sleeved on the outer side of the permanent magnet; the mass block comprises a coil framework made of a non-magnetic material and a coil assembly fixed on the coil framework; and the triboelectric assembly comprises a triboelectric fixed part fixed on the shell and a triboelectric movable part fixed on the mass block. The collector is high in capacity of resisting interference of external magnetic materials, high in kinetic energy collection efficiency under the micro-vibration working condition, high in output power of unit volume and capable of being used for wave energy power generation.
Description
technical field [0001] The invention relates to the technical field of kinetic energy collection, in particular to an array type magnetic liquid kinetic energy collector based on coil suspension. Background technique [0002] The development of sustainable clean energy can effectively solve the current global pollution and resource problems. Among them, kinetic energy is a kind of clean energy that widely exists in nature, such as ocean wave and tidal activities, the movement of people and animals, and the vibration of objects caused by wind and other factors. The generation of electric energy has very important research value. [0003] The electromagnetic kinetic energy harvester, which converts the kinetic energy of moving objects into electrical energy through the law of electromagnetic induction, has outstanding advantages such as low impedance, high output power, high reliability and long service life, and has broad application prospects. [0004] The existing electro...
