A buoy type ocean wave power generation device

Abstract

The invention discloses a buoy type sea wave power generation device. The buoy type sea wave power generation device comprises a power generation device, a buoy tied at the upper end of the power generation device, and a mooring device for fixing the power generation device on a seabed, wherein the power generation device comprises an enclosed linear power generation device of which the periphery is provided with insulated coils, the middle part is provided with a first permanent magnet and the two ends consist of an upper support frame positioned at the upper ends of the insulated coils and a middle separating plate positioned at the lower ends of the insulated coils, and a turbine power generation device which is positioned below the linear power generation device and of which the periphery is provided with second permanent magnets and the middle part is provided with a coil-comprising turbine. According to the buoy type sea wave power generation device provided by the invention, power is generated by converting the energy of sea waves into linear motion of the permanent magnets on one hand, and power can be generated by converting the energy of the sea waves into rotation of the turbine on the other hand in a complementary way, so that the power generation efficiency is increased greatly. Meanwhile, the power generation device is placed under water, so that power can be generated normally even under a severe sea condition, and the continuity of power generation is ensured.

Description

technical field [0001] The invention relates to a device for generating electricity using wave energy, in particular to a buoy type ocean wave power generating device, which belongs to the field of marine renewable energy. Background technique [0002] With the depletion of terrestrial energy, the development and utilization of ocean energy has increasingly become the focus of attention of all countries. Ocean energy mainly refers to energy in the form of tides, waves, ocean currents, temperature and salinity differences. Compared with fossil energy on land, these energy sources are renewable, will never be exhausted, and will not cause any pollution. As a result, various equipment and devices that use ocean energy to generate electricity have emerged as the times require. [0003] Wave energy refers to the kinetic energy and potential energy of waves on the surface of the ocean, which is mainly generated by the wind transferring energy to the ocean. It is estimated that t...

[0004] The above-mentioned wave energy generation device directly converts the wave energy into electric energy, which reduces the secondary conversion of energy, but seawater will have a certain loss along the way during the transportation of the submarine pipeline, and considering the pressure head of energy, the installation height of the turbine Further consideration is also required

[0005] In addition, the principle of the device using wave energy to generate electricity is to use the wave to drive the floating ball to move up and down to cut the magnetic field line, and to use the principle of electromagnetic induction to generate electricity. However, this type of wave power generation device has low energy utilization and can only use a small part of the wave energy.
