Magnetic suspension and electromagnetic power generation coupled two-degree-of-freedom flow-induced vibration ocean current generator

Abstract

The invention discloses a magnetic suspension and electromagnetic power generation coupled two-degree-of-freedom flow-induced vibration ocean current generator which comprises a base, stator winding structures are symmetrically installed at the two ends of the base, a vibrator structure is arranged between the stator winding structures on the two sides, the vibrator structure is installed on the base, and each stator winding structure comprises a stator magnetic disc. Armature discs are installed at the ends, close to each other, of the stator magnetic discs on the two sides, a plurality of coil windings are annularly arrayed on the surfaces of the armature discs, the vibrator structure comprises a vibrator, vibrator magnetic discs are installed at the two ends of the vibrator, and the vibrator magnetic discs and the stator magnetic discs repel each other. A permanent magnet disk structure is adopted to replace a metal spring structure, no mechanical contact exists between the structures, the energy loss is relatively reduced, and the device can capture energy to a greater extent, so that the power generation efficiency is improved; a double-stator and single-vibrator structure is adopted, the rotational inertia of the device is small, the heat dissipation effect is good, a magnetic disk structure in the structure enables the device to move in two degrees of freedom, the magnetic flux change between the device and a winding is increased, and therefore the power generation efficiency is improved.

Description

technical field [0001] The invention relates to an ocean current energy generating device, in particular to a two-degree-of-freedom flow-induced vibration ocean current generator coupled with magnetic levitation and electromagnetic power generation. Background technique [0002] With the development of science and technology, coal, oil, natural gas and other fossil fuels are further developed and utilized, and the shortage of non-renewable energy has caused people to turn their attention to renewable energy such as solar energy, wind energy, and ocean energy. In the development and utilization of various types of renewable energy, the development and utilization of marine energy has received more and more attention, with strong predictability and stable load, which is especially suitable for the development and utilization of new marine energy. [0003] The phenomenon of flow-induced vibration means that when a fluid flows through a solid, alternating fluid forces are applie...
