Abstract
The present invention is a kind of novel wave energy generating set, adopts buoyancy aid to be connected the rocking bar middle part through soft lashing, and the rocking bar head is vertically installed close coupled type generator under the straight expelling water of displacement turbine, is made up of from displacement turbine and directly driving type underwater power generation machine close coupled type.The rocking bar rear portion is connected fixedly pile top, seabed through rotating shaft, and the rocking bar middle part is equipped with lower fulcrum bar, the soft rope of upper limit, can limit the amplitude that rocking bar is downward and make progress.Because the rocking bar link position is different, it is vertically arranged from displacement horizontal axis direct drive generator to pass to head after the moving up and down of wave energy amplified through the leverage of rocking bar, this generator and seawater formation relative movement; Thereby the close coupled type turbine rotary electrification at pushing generator two ends; Whole apparatus structure is simple, reliable operation, and the displacement process need not additional energy; Energy need not the secondary conversion; Have anti-seawater surge destruction characteristic simultaneously, so typhoon protection is can long-time in briny environment, continual and steady work.
Description
Technical field
The invention belongs to the renewable energy source domain, relate to a kind of new device that obtains the generating of waves of seawater energy.This device utilizes wave energy to drive rocking bar and the two-way close coupled type of rocking bar head is done relative motion from displacement turbine and seawater, generate electricity thereby wave energy is converted into the turbine rotating energy.
Background technique
At present, traditional fossil energy is day by day exhausted, and international energy crisis and lasting environmental deterioration make the numerous and confused exploitation dynamics that strengthens emerging renewable energy sources in various countries, and marine energy is a kind of of renewable energy sources, and reserves are abundant.Wave energy reserves capable of using are maximum in the marine energy, but it utilizes difficulty also very big.Areas such as Britain is coastal, U.S.West Coast all are the abundant regions of wave energy; The wave energy apparatus style is extremely many, is called as inventor's paradise, but the device of also incompetent so far mature and reliable operation occurs; Its main cause is the considerable damage power of wave energy, makes device difficult bear.Ocean energy buoyancy aid of the present invention-rocking bar direct-drive type wave energy turbogenerator is a kind of new-type wave ability electricity generating device; This device is converted into the relative movement of two-way close coupled type from displacement turbine and seawater with moving up and down of wave energy; Thereby utilize turbine that this relative movement is converted into rotating drive and directly drive generator for electricity generation under water; Reduced the energy secondary and transformed and to have improved efficient, installed simultaneously except that buoyancy aid all below the sea, buoyancy aid also has the gas of charging and discharging sinking function; Can effectively avoid the attack of typhoon and billow, therefore device has higher efficient and reliability.
Summary of the invention
Goal of the invention:
The objective of the invention is to research and develop a kind of novel wave energy generating set; This device is moving up and down of wave energy to be amplified drive through the arm of force do relative motion from displacement turbine and seawater with the maximum difference of wave energy generating set in the past; Because can be to same direction rotation under two-way marine stream from the displacement turbine; Therefore can wave energy be converted into rotation, drive generator for electricity generation.The secondary that its whole efficiency will be higher than traditional wave energy transforms energy, and structure is also more simple.Big of conventional wave wave energy generating set is the floating type device simultaneously; Its Anti-Typhoon, anti-billow ability, often the short time operation promptly goes to pot, and device for mechanical of the present invention part is all below the sea; Only the buoyancy aid part is at the water surface; The invasion and attack that buoyancy aid also can adopt the mode of venting dive to hide Super Typhoon before typhoon arrives make that so whole device is Anti-Typhoon, the ability of billow is greatly improved, and also make device reliability that assurance has been arranged.
Technological scheme:
Adopt buoyancy aid to be connected the rocking bar middle part through soft lashing, the rocking bar head is vertically installed close coupled type generator under the straight expelling water of displacement turbine, and this generator is made up of from displacement turbine and directly driving type underwater power generation machine close coupled type.The rocking bar rear portion is connected fixedly pile top, seabed through rotating shaft, and the rocking bar middle part is equipped with lower fulcrum bar, the soft rope of upper limit, can limit the amplitude that rocking bar is downward and make progress.When wave arrives; Buoyancy aid moves up and down with wave, drives rocking bar and does oscillating motion, because the rocking bar link position is different; It is vertically arranged from displacement horizontal axis direct drive generator to pass to head after the leverage through rocking bar of moving up and down of wave energy is amplified; This generator and seawater form relative movement, thus the close coupled type turbine rotary electrification at pushing generator two ends, and relative movement is controlled amplitude peak through fixing position-limit foot and tie-down cable up and down; Prevent that generator bump seabed or lifting are excessive, limit simultaneously and can make power transmission cable do swing behind the generator pendulum angle to have prevented the cable winding at small angle.From the big solidity blade of displacement turbine employing symmetrical airfoil (NACA0012), root of blade has from displacement hydrodynamic force compensation winglet, and blade and wheel hub joint are provided with spacing control system, make blade in ± 14 °, adjust angle, to cater to flow path direction.When incoming flow changes direction; Blade produces deflecting torque by hydrodynamic force compensation winglet; Make blade change pitch, and be limited in 14 ° by the blade root limit controller, this moment, blade was in the best angle of attack; Thereby having the highest conversion efficiency, the blade sense of rotation does not still change in reverse incoming flow.When typhoon can in advance the buoyancy aid bleed valve opens temporarily, will install integral body and sink under the water and protect, typhoon can be discharged the buoyancy aid internal gas through gas charging valve later; The recovery device working state when needing repairing, can be decontroled supporting foot when high water mark; Because it is supported on the seabed downward vertically gravity; The generator head surfaces when low water mark, can keep in repair at this moment, does not need special-purpose hanging device and ship to greatly reduce maintenance cost.
The invention effect
The present invention is a kind of novel wave energy generating set, and whole apparatus structure is simple, reliable operation; The displacement process need not additional energy; Energy need not the secondary conversion, has anti-seawater surge destruction characteristic simultaneously, so can long-time in briny environment, continual and steady work.
