Abstract
The invention discloses a novel wave energy generating device. In the device, a floating body is connected to the middle of a rocking bar through a flexible lanyard; a coaxial self pitch-changing turbine direct drive underwater power generator is vertically arranged at the head of the rocking bar and consists of a coaxial self pitch-changing turbine and a direct drive type underwater power generator. The rear part of the rocking bar is connected to the upper part of a seabed fixed pile through a rotating shaft; and a lower support rod and an upper limiting flexible cable are arranged at the middle part of the rocking bar and can be used for limiting the downward and upward magnitude of the rocking bar. Since the connecting positions of the rocking bar are different, the vertical movement of the wave energy is amplified by using the lever action of the rocking bar and is then transmitted to a self pitch-changing horizontal shaft direct drive type generator which is vertically arranged on the head; and the generator and sea water form relative movement, thereby the coaxial turbines at two ends of the generator are pushed to generate power. The whole device has a simple structure and reliability in work; extra energy in the pitch change process is avoided; secondary conversion of energy is avoided; and meanwhile, the novel wave energy generating device has the characteristics of resisting sea water surge and damage and capability of resisting typhoon, thus the novel wave energy generating device can work continuously and stably in the sea water environment for a long time.
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.The marine energy Wave can be able to utilize reserves maximum, but it utilizes difficulty also very big.The 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 so far also device appearance of incompetent mature and reliable operation, its main cause is the considerable damage power of wave energy, so that device is difficult to bear.Ocean energy floating body-rocking bar direct drive type wave energy turbine generator of the present invention is a kind of new-type wave energy electricity generating device, this device is converted into two-way close coupled type from the relative movement of 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 the generator generating under water, reduce the energy secondary conversion and improved efficient, external all below the sea with the timer de-floating, buoyancy aid also has inflation/deflation 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 by 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 wave energy can be converted into rotation, drive the generator generating.Its whole efficiency will be higher than the secondary conversion energy of traditional wave energy, and structure is also more simple.Large of conventional wave wave energy generating set is the floating type device simultaneously, its Anti-Typhoon, anti-billow ability, often the short time operation namely goes to pot, and device for mechanical part of the present invention is all below the sea, only the buoyancy aid part is at the water surface, buoyancy aid also can adopt the mode invasion and attack of hiding Super Typhoon of venting dive before typhoon, like this so that whole device ability Anti-Typhoon, billow be greatly improved, also so that device reliability has had assurance.
Technological scheme:
Adopt buoyancy aid to be connected to the rocking bar middle part by soft lashing, rocking bar head at right angle setting close coupled type generator under the straight expelling water of displacement turbine, this generator is comprised of from displacement turbine and directly driving type underwater power generator close coupled type.The rocking bar rear portion is connected to fixedly pile top, seabed by rotating shaft, and the rocking bar middle part is equipped with lower fulcrum bar, the soft rope of upper limit, can limit rocking bar downwards and the amplitude that makes progress.When wave arrives, buoyancy aid moves up and down with wave, drive rocking bar and do 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 by rocking bar of moving up and down of wave energy is amplified, this generator and seawater form relative movement, thereby the close coupled type turbine rotary electrification at pushing generator two ends, relative movement is controlled amplitude peak by 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 to swing at small angle behind the generator pendulum angle to have prevented cable winding.Adopt the large solidity blade of symmetrical airfoil (NACA0012) from the displacement turbine, root of blade is with compensating winglet from the displacement hydrodynamic force, blade and wheel hub joint are provided with limit control system, make blade adjust angle in ± 14 °, to cater to flow path direction.When incoming flow changes nyctitropic the time, 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 rotary direction does not still change in reverse incoming flow.When typhoon, can in advance the buoyancy aid bleed valve be opened; to install integral body sinks under the water and protects; typhoon can be discharged the buoyancy aid internal gas by 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 hoisting equipment 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 simultaneously anti-seawater surge destruction characteristic, so can long-time in briny environment, continual and steady work.
