Shore base floater type wave energy collecting device with tidal range regulating function

Abstract

The invention discloses a shore base floater type wave energy collecting device with a tidal range regulating function. By means of the shore base floater type wave energy collecting device, efficientand reliable transfer of fluctuating kinetic energy in the tidal changing process can be guaranteed. The shore base floater type wave energy collecting device comprises a fixed beam, a movable beam,a pulley block composed of multiple fixed pulleys, a power generation input transmission mechanism, a counterweight mechanism, a fixed beam support, a movable beam lifting driving mechanism and a tidal range regulating control unit. A floater pulling rope is connected with one end of a chain after penetrating the multiple fixed pulleys constituting the pulley block sequentially. The chain meshes with a chain wheel. The other end of the chain is connected with one end of a counterweight pulling rope. The tidal range regulating control unit comprises a tidal range regulating controller and a counterweight block amplitude collecting controller. Rising and falling of the movable beam is controlled by the tidal range regulating controller, and thus the length, which the pulley block accommodates, of the floater pulling rope is regulated so that tensile force is kept by the floater pulling rope, efficient and reliable energy transfer of fluctuating kinetic energy is achieved, and stable operation of a power generation system in the tidal range changing process is guaranteed.

Description

technical field [0001] The invention relates to the technical field of ocean wave power generation, and more specifically, relates to a shore-based floater type wave energy collection device with a tidal range adjustment function. Background technique [0002] Wave energy is a kind of clean energy. The seawater fluctuates under the action of the wind. Through the floats floating on the sea surface, the undulating kinetic energy of the waves can be converted into the mechanical energy of the gearbox rotation, and finally generate electricity through the generator. [0003] At present, the research on wave power generation technology is just in its infancy. Most of the wave power stations are floating wave power ships floating in the deep sea, and the shore-based power stations are still in the blank stage. The advantage of the shore-based wave power station is that the generated electric energy can be used directly on the shore or on land. But one problem that must be solve...

AI Technical Summary

Problems solved by technology

At present, because the length of the traction rope connecting the buoy and the gearbox is not adjustable during the tidal change, the undulating kinetic energy of the buoy cannot be transmitted effectively and reliably, and the conversion of the undulating kinetic energy of the buoy is affected, which affects the stability of wave power generation and reduces the wave power efficiency
