An oscillating water column double air chamber wave energy device with adjustable shore resonance mechanism

Abstract

The invention provides an onshore resonance mechanism adjustable vibrating water column double air chamber wave energy device which is composed of a plurality of vibrating water column power generation device units. Each vibrating water column power generation device unit is composed of a front vertical straight plate, a front air chamber structure, a front opened horizontal plate, a front air flow channel, a front air turbine, a middle vertical plate, a back air chamber structure, a back horizontal plate, a back vertical straight plate, a back air flow channel, a back air turbine, a spring structure system, a back vertical plate connecting structure, an anchorage structure, an anchorage structure connecting structure, a pedestal and a shoreside inherent straight wall structure. By means of the double air chamber structure, the width of the air chamber of the front air chamber structure is fixed and unchanged and the width of the air chamber of the back air chamber structure is adjusted self-adaptively under the action of waves, so that probability and conditions for generation of multiple resonance mechanisms of the whole system are provided, and an obvious effect of improving theintegral working performance of the device is also achieved.

Description

technical field [0001] The invention relates to an oscillating water column type wave energy generating device, in particular to an oscillating water column double air chamber wave energy generating device with an adjustable resonance mechanism for shore construction. Background technique [0002] Blue is the main color of the earth. The vast ocean, which occupies 70% of the earth's surface, enriches the human table with a variety of seafood, drives cars with oil and natural gas that exceeds land reserves, lights up light bulbs, and constantly changes tides and waves. , salinity difference, ocean currents and other forms show a rich treasure house of resources. Since the oil crisis in the 1970s opened a new era of renewable energy research, under the situation that the development of land resources has been stretched, more and more people are gradually turning their attention to the sky and sea, marine environment research and marine resources. Development has become the on...

Problems solved by technology

That is, considering the typical randomness characteristics of the wave height and cycle in the real ocean environment, a device that can overcome the difficulty of changing the properties of the traditional oscillating water column wave energy device is weak in adaptability to waves, and the wave energy The shore-type oscillating water column double-chamber wave energy device with the inherent bottleneck problem of low extraction efficiency can not only meet the expectations of the device's working performance efficiently, but also has obvious advantages in saving engineering construction costs
