Abstract
A wave energy absorber is composed of a bottom board, a container, a spring, a locating mechanism, a pressing block body and pipelines. The container, the spring and the locating mechanism are fixedly connected between the bottom board and the pressing block body. The locating mechanism prevents the pressing block body and the bottom board from moving relatively in a reciprocating mode. The wave energy absorber is placed on and fixedly connected to an ocean floating body and the pressing block body moves in a reciprocating mode relative to the container and the bottom board under the effects of fluctuating wave energy and the spring, so that the volume of the container is continuously increased and reduced, positive pressure and negative pressure are generated alternately in the container, water flow or an air medium in ocean continuously flows into the wave energy absorber when negative pressure is generated, the water flow or the air medium is pressed out of the wave energy absorber when positive pressure is generated, a power generation mechanism is driven by the water flow or the air medium flowing ceaselessly to generate power, and wave energy is converted into electric energy. According to the wave energy absorber, all power generation parts do not make direct contact with sea water, the wave energy absorber floats on the sea surface to absorb wave energy, the power generation parts can not be corroded by sea water and can be prevented from being impacted and damaged by storms and surges.
Description
Technical field
The present invention relates to a kind of wave energy absorber.Specifically, a kind of being exactly placed on marine float body floats on a kind of equipment that rough water carrys out sorption enhanced wave energy.
Background technique
Wave-energy power generation, present great majority be utilize electrical generation components as float directly with contact with sea water to gather wave energy, then the wave energy of collection is passed to the mechanisms such as oil hydraulic pump with kinetic energy form and carrys out drive electrical generators and generate electricity.
The deficiency of this method is that wave energy acquisition component directly contacts with seawater throughout the year, and the corrosion failure by seawater is serious, and seashore limit often built in by this power generating equipment and power station, often will face the threat of the impact failure of tide and wave storm.
Summary of the invention
Wave energy absorber disclosed by the invention, all devices parts directly do not contact with seawater, avoid seawater to the corrosion of electrical generation components and destruction, wave energy absorber is placed and is fixed on floating body, floating body rises and falls with wave, and wave energy absorber internals occurs correspondingly to move, and wave energy is changed into fluid dynamic energy, drive electrical power generators with fluid dynamic energy, reach the effect of sorption enhanced wave energy.
Wave energy absorber disclosed in this invention, is made up of base plate, container, spring, positioning means, briquetting body, pipeline, and wave energy absorber is placed and is fixedly connected on floating body, and wherein base plate also can directly as floating body;
Container, spring and positioning means are fixedly connected on base plate and briquetting respectively, and positioning means restriction briquetting and base plate do relatively reciprocating motion; Spring and positioning means can be placed in container, also can be placed in outside container.
Container wall is connected with pipeline, and the pipeline be connected with container wall is divided into the pipeline filling valve and the pipeline not filling valve.Container is connected with and flow valve and the pipeline flowing out valve is housed, and the medium in container only by flowing out valve flow container, is flowed in container by flow valve.Do not fill the pipeline of valve, the medium in container enters and all passes through this pipeline with flowing out.
Briquetting body is for wave energy absorber provides gravity, with the active force of balance spring, makes the volume of container can occur to change with reducing or increase in the bad border of heaving sea wave.When vessel volume reduces, airtight volume internal pressure increases, and the flowing medium in container is forced out container; When the volume of container increases, form negative pressure in airtight volume, flowing medium is pressed in container from outside by barometric pressure.
Briquetting body can be an one-piece element, also can be the briquetting body one-piece element be made up of moving member, connected element and briquetting basin body three unit; The moving member of briquetting body is directly close to container wall and relative to the reciprocating briquetting body unit of container; Briquetting basin body is the briquetting body unit of splendid attire mass, and briquetting basin body also can be directly the briquetting body unit with fixed weight object; The connected element of briquetting body is connected and fixed the moving member of briquetting body and briquetting basin body becomes overall briquetting body unit.
The weight of briquetting body is equal to or greater than the initial load of spring, is less than the maximum load of spring.If the weight of briquetting body is less than the initial load of camber of spring, to the prestowage of briquetting body, other cheap practical materials such as stone can be adopted to be placed on briquetting basin body to increase the weight of briquetting body, to make the gravity of briquetting body and spring supporting power be in state of equilibrium.
Container has flexible container and rigid container.
Flexible container wall has flexibility or elasticity, and during flexible container distortion, volume changes, after pressure releases, flexible container self elastic reaction or spring act under can resile.Flexible container is directly fixedly connected with briquetting body and base plate.
The hollow body of rigid container to be container wall be rigidity, the sealed volume space that the volume of rigid container is made up of briquetting body, rigid container hollow body and base plate.
