Synchronous power generation and vibration suppression device and method for sleeving rotatable abacus-shaped power generation frame

Abstract

The invention relates to a synchronous power generation and vibration suppression device and method for sleeving a rotatable abacus-shaped power generation frame. The device is composed of a sleeve assembly and a rotating assembly. A calabash-shaped protective cover is sleeved outside a marine riser, and the back flow side of the calabash-shaped protective cover is connected with three tail supporting frames which are arranged at intervals of 45 degrees. An ocean current impacts the tail supporting frames to drive the whole device to rotate around the marine riser. Under the combined action of axial diameter change and rotation of the calabash-shaped protective cover, stretching and retracting of a horizontal spring and a vertical spring, movement of a mass ball and swinging of a round hole tail plate and a square hole tail plate, formation and development of a marine riser streaming vortex are destroyed, and then vortex-induced vibration is restrained. The springs continuously stretch out and draw back under the action of ocean current impact and streaming, a magnetic bar is driven to move and displace, a power generation coil and an embedded coil cut magnetic induction lines formed by the magnetic bar, induction current is generated, and ocean current energy conversion is achieved.

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 synchronous power generation and vibration suppression device and method that is fitted with a rotatable abacus-shaped power generation rack. Background technique [0002] At present, my country's energy consumption structure is still dominated by traditional fossil energy. On the one hand, the proven fossil energy on land gradually decreases with the extension of mining time, and the environmental pollution caused by its combustion is profoundly affecting people's living environment. On the other hand, the development and utilization technology of renewable energy is immature, and its proportion in the existing energy supply is extremely low. Therefore, it is urgent to speed up the technological research and development of clean and renewable energy. [0003] Ocean energy, known as "blue...

Problems solved by technology

It has become the consensus of mankind to increase and speed up the development of ocean energy. However, the physical environment of the ocean is complex and changeable. In the process of developing ocean energy, it is inevitable to face the problem of vibration response of structures under the impact of ocean waves and currents.
