The invention discloses a guide rail type combined wave power generation device which comprises a guide rail support assembly, a pulley assembly, a heaving oscillation wave energy capture float, a horizontal wave energy capture float, an energy exchange mechanism assembly, a pole-changing multi-speed permanent magnetic direct-driven generator assembly, a cable barrel and an anchor. By means of a rack on a universal guide rail assembly and a gear on the energy exchange mechanism assembly, heaving oscillation (up and down movement) energy of the waves is captured. Horizontal energy of the waves is captured by means of the horizontal wave energy capture float. The guide rail type combined wave power generation device is suitable for waves of various types, can collect energy, and achieves optimized collection of the wave energy. The guide rail type combined wave power generation device is suitable for the waves of various shapes, efficient in wave energy conversion, strong in anti-wind and anti-wave performance, low in cost and easy to maintain.
Description
technical field [0001] The invention relates to the field of power generation, in particular to a rail-type combined wave power generation device capable of simultaneously capturing wave longitudinal potential energy and transverse impact kinetic energy. Background technique [0002] The ocean accounts for 70% of the earth's surface area. Ocean wave energy is an inexhaustible renewable energy source. How to efficiently utilize wave energy and turn it into usable electrical energy has been an important subject of research. [0003] The ocean is affected by changes in natural factors, and the wave energy of the ocean is irregular and unstable (from time to time, the average power is 1 / 10 to 1 / 7 of the peak power), and the motion characteristics are reciprocating: surge, heave, cluster Shaking, low movement speed: the maximum speed is 0.8m / s under big waves, and high power: the instantaneous power is 100kw / m. [0004] The technical difficulty of utilizing wave energy: how to c...
