A device and method for combined power generation and vibration suppression of a rotary pendulum

Abstract

The invention relates to a swing pendulum combined power generation and vibration suppression device and method. The device is composed of three parts including a swing pendulum system, a mooring system and a circuit output system. When an ocean current flows through a subordinate stand pipe, if two power generating tail plates are asymmetric about the ocean current coming direction, seawater impacts the two power generating tail plates to generate different torques, and the entire swing pendulum system is pushed to rotate around a power collection stand pipe until the swivel pendulum system is located on the backflow side of the power collection stand pipe and attack angles between the ocean current and the two power generating tail plates remain the same. At the time, the power generation tail plates swing back and forth under the impact of the ocean current, a magnetic pole sleeve is driven to rotate to generate power, generated electric energy is transmitted to a waterproof electric slip ring through a power transmission line, and then the electric energy is transmitted out through the power collection stand pipe. The reciprocating swing of the power generation tail plates disrupts the development and migration of vortexes falling off from the power collection stand pipe, so that a periodic flow field at the rear of the power collection stand pipe is disturbed, vortex-induced vibration of the power collection stand pipe is effectively suppressed, and the service life of the power collection stand pipe is prolonged.

Description

technical field [0001] The invention belongs to the technical field of marine new energy development and utilization and vortex-induced vibration suppression, and in particular relates to a device and method for combined rotary-pendulum power generation and vibration suppression. Background technique [0002] Electric energy is an indispensable form of energy for people's production and life. At present, thermal power generation is still the main power generation method in my country. Thermal power generation not only consumes a large amount of coal resources, but also causes serious environmental pollution. Under the background of the contemporary era that requires both green water and lush mountains and golden mountains and silver mountains, how to develop new and non-polluting power generation methods is a potential breakthrough for the sustainable development of our society. [0003] With the continuous in-depth development of the social economy, the demand for energy c...
