AI Technical Summary

Technical Problem

The core components of traditional oscillating float wave energy devices are easily corroded by seawater, leading to device failure and shortened lifespan. At the same time, the energy output is unstable, affecting power generation efficiency and economy.

Method used

Design an energy conversion system with a built-in pendulum wave energy generator. All energy conversion components are enclosed inside the float and adopt a fully enclosed watertight structure. The power conversion system is driven by a linear slide rail slider kinematic pair and bidirectional hydraulic pipes to avoid seawater corrosion. The hydraulic energy conversion is driven by the sliding of the slider on the track.

Benefits of technology

It improves the reliability and safety of the device, extends its service life, reduces maintenance difficulty and operating costs, and enhances energy conversion efficiency and stability.

Abstract

This invention relates to the field of marine wave energy generation technology, and proposes a pendulum-type wave energy generation device with an integrated energy conversion system. The device includes a wave-absorbing float equipped with power generation components, the float being boat-shaped. The power generation components include a linear slide rail slider joint, bidirectional hydraulic pipes, and a power conversion system cabinet. The linear slide rail slider joint is mounted at both ends of the boat-shaped structure and is driven by the power conversion system cabinet through the bidirectional hydraulic pipes. This invention employs a fully enclosed watertight structure, with all energy conversion components inside the float, avoiding corrosion of hydraulic and electrical components by seawater or salt spray, significantly improving the service life of the hydraulic energy conversion system, and enhancing the reliability and safety of the wave energy device. The use of a single float to absorb wave energy results in good overall device integrity, facilitating overall hoisting and maintenance. Furthermore, the boat-like structure also facilitates towing, deployment, and recovery.
