Efficient wave power generation device under natural coordinate system

Abstract

The invention discloses an efficient wave power generation device under a natural coordinate system. The device comprises three power generation units; each power generation unit comprises an inner buoy and an outer buoy which are arranged in a nested manner; the inner buoy is longer than the outer buoy; coils re arranged in the inner buoy; and the outer buoy is connected with permanent magnets through a support. According to the device, the permanent magnets are mounted on the outer buoy, the coils are mounted on the inner buoy, relative movement of the inner buoy and the outer buoy is realized through fluctuation of waves, induction current is produced in closed coil loops, and wave power generation is realized. The power generation manner is a primary energy conversion manner, and the loss in the secondary energy conversion process in the prior art is reduced, so that the utilization efficiency of wave energy is improved. The X-direction power generation unit, the Y-direction power generation unit and the Z-direction power generation unit are designed according to the principle of permanent-magnetic linear power generators, and the wave energy in the three directions can be utilized simultaneously, so that the power generation power of the device is improved.

Description

technical field [0001] The invention relates to power generation technology, in particular to a high-efficiency wave energy power generation device in a natural coordinate system. Background technique [0002] The earth's petrochemical resources are limited, but human's demand for energy is increasing day by day, and the energy crisis is increasing day by day. In order to solve this problem, it is imperative to research, develop and utilize renewable energy. Ocean energy is an inexhaustible green renewable energy source. The electric energy stored in ocean waves on the earth can reach 5000GW. my country's coastline is long and the available wave energy is extremely rich. A new type of high-efficiency floating wave power generation system has emerged as the times require. It can realize large-scale grid-connected power generation, so it has important theoretical and practical significance. However, at present, the use of wave energy to generate electricity often adopts secon...
