A fully enclosed inertial point-suction wave energy device

Abstract

The invention discloses a full-closed inertial point sucking type wave energy device and belongs to the technical field of wave energy power generation. The full-closed inertial point sucking type wave energy device comprises a floater, a mechanical system, a permanent magnetic linear power generator, an electronic control module and an anchoring device. The floater is in a full-closed type, and is used for capturing the energy of waves, the kinetic energy and the potential energy of the waves are converted into the mechanical energy of shaking movement; the mechanical system converts the mechanical energy of the shaking movement of the floater into the mechanical energy of the linear oscillating movement of a mass block and a transmission shaft; and the permanent magnetic linear power generator is linkage with the transmission shaft and the mass block, and the mechanical energy of the oscillating movement of the mass block and the transmission shaft is converted into the electric energy. The full-closed inertial point sucking type wave energy device overcomes the defects of an existing oscillating floater type wave energy power generating device, the device is unique in shape, theoscillating frequency of the system is controllable, the environment adaptive capacity is high, the energy converting efficiency is high, it is effectively achieved that the wave energy device is resistant to seawater corrosion, the system is high in reliable, sea and land installing and maintaining are facilitated, the production and building cost is low, and wide application prospects are achieved.

Description
