Novel wave energy resonance wave-absorbing power generation device

Abstract

The invention discloses a novel wave energy resonance wave-absorbing power generation device, which is characterized in that a counterweight structure in a floating barrel is adjusted and an elastic device is added, so that the natural oscillation frequency or frequency spectrum formed by the counterweight structure device of the floating barrel is the same as or similar to the incident wave frequency or frequency spectrum, and a resonance effect is generated; therefore, the floating barrel can effectively pull the power pump, and liquid in the pump drives the turbine to rotate to drive the motor to generate electricity. After the floating barrel absorbs the fluctuation kinetic energy, the inertia effect compensates the process of low-energy waves such as weak waves existing in the actual sea condition irregular waves for a short time, so that the output change of the floating barrel tends to be stable and approximate to regular waves. According to the method, the generated electric energy is stable, and grid-connected application is facilitated. According to the device, the most ideal floating barrel resonant cavity configuration elastic design can be achieved through a test, and after irregular waves incident by sea waves are subjected to floating barrel resonance adjustment, compensation and conversion, power output is approximate to regular waves with the average wave height amplified. In the figure, (1) represents an actual sea condition irregular wave which is an incident sea wave acting on the floating barrel, (2) is a floating barrel wave-absorbing resonance device, and (3) represents that the power output of the floating barrel is an approximately stable regular wave.

Description

technical field [0001] The invention relates to the technical field of marine wave energy power generation application. In particular, it relates to a novel high-efficiency wave energy absorbing power generation device designed by utilizing the principle of resonance. The present invention is applicable to the floating barrel wave absorbing power generation device that is submerged in water or floating on the water surface or semi-submerged in water, and it is not limited to the number of attached pumps and the location of anchor chains. Background technique [0002] Humans have a long history of exploring wave energy power generation. Most of them float the devices on the sea surface and use the characteristics of the sea surface such as strong winds and waves to generate electricity. However, due to extreme weather processes such as typhoons sometimes occurring at sea, the destructive force of the sea surface is relatively large, and many devices cannot be used for a long...
