Multi-oscillating floater wave-driven hydraulic power generating device

Abstract

The invention discloses a multi-oscillating floater wave-driven hydraulic power generating device. The multi-oscillating floater wave-driven hydraulic power generating device comprises an installing platform, a generator cabin, a rotating shaft, a plurality of oscillating floater sets and a hydraulic power generating device, wherein the plurality of oscillating floater sets are arranged into an array on a sea surface, and can collect wave energy at different positions at the same time and drive an overrunning coupler by a transmission rope to synchronously convert the wave energy into the mechanical energy of the rotating shaft; and the rotating shaft drives a permanent-magnet generator to generate power. The multi-oscillating floater wave-driven hydraulic power generating device can collect the wave energy of a plurality of oscillating floaters at the same time, so that large-scale wave-driven power generation is realized, the cost performance of the wave-driven power generation and the wave energy collecting stability are improved; all hydraulic equipment and power generating equipment is arranged on the sea surface and does not contact sea water, so that the multi-oscillating floater wave-driven hydraulic power generating device is difficult to corrode and convenient to install and regulate and maintain.

Description

technical field [0001] The patent of the invention belongs to the technical field of marine renewable energy utilization, and in particular relates to a multi-oscillating buoy type wave energy hydraulic power generation device. Background technique [0002] Wave energy is the most widely distributed and energy-dense renewable energy in the ocean. Large-scale collection of wave energy and converting it into electrical energy can solve the problem of power supply for island residents and marine equipment, and can also provide a steady stream of electrical energy for marine environmental testing and marine fisheries. According to the results of the influence of existing wave energy device technologies at home and abroad on wave energy flow, they can be roughly divided into three categories: point absorption, consumption and cut-off. Oscillating float wave energy harvesting technology belongs to the point absorption type, relying on the up and down movement of the oscillating f...

AI Technical Summary

Problems solved by technology

Therefore, the wave energy absorption efficiency is low, the power generation stability is poor, the power quality is not high, and the impact on the entire power generation device is relatively large

On the other hand, existing wave energy generating devices cannot collect wave energy at different locations on the sea surface at the same time. Due to the limitation of the volume and weight of a single oscillating float, the total power of wave energy collected is limited, and large-scale power generation cannot be performed.
