Abstract

The invention relates to a double-direction guide vane impact turbine wave-force power generation system. The system comprises a water port arranged underwater, wherein the water port is provided with an overflowing channel through an outer water channel, the overflowing channel is provided with a water turbine rotor driving an electric generator, the overflowing channel is connected with the bottom of a water box through an inner water channel, the bottom, connected with the inner water channel, of the water box is relatively small, the upper portion of the water box is relatively large, the bottom of the water box is in smooth transition connection with the upper portion of the water box to form a horn shape, an upper opening of the water box is open, the water turbine rotor is an axial water turbine rotor rotating in a single direction. According to the double-direction guide vane impact turbine wave-force power generation system, a double-direction guide vane impact turbine which is a water turbine with impact water flow flowing in the axial direction of the rotor is adopted. By using the axial water turbine, compared with an existing system using a double-impact water turbine, the double-direction guide vane impact turbine wave-force power generation system has the advantages that the length of the flowing channel of the rotor is irrelevant to the diameter of the rotor, the diameter of the rotor can be freely selected according to the magnitude of energy contained in the impact water flow, and inherent frequency of the system will not be affected.

Description

technical field

[0001] The present invention relates to a two-way guide vane impact type turbine wave power generation system and method, which is a renewable energy technology and a wave energy capture with automatic adaptation to the wave frequency range developed by the principle of broadband resonance. Power Generation Systems and Design Methods. Background technique

[0002] Wave energy includes energy of various frequencies, and its energy frequency band is a frequency interval. Correspondingly, the system natural frequency of the wave energy capture device is a point, only when the system natural frequency is equal to the main frequency in the wave frequency interval and resonates , have higher wave energy capture efficiency. Even so, existing wave energy capture devices only capture wave energy in a narrow range around its natural frequency. The Chinese patent "A Broadband Wave Energy Capture Device and Design Method for Wave Power Generation" (application number: ...
