Description
Technical field
The invention belongs to marine energy utilization and renewable energy power generation field, relate to the equipment that utilizes tidal energy and sea wave energy generating.
Background technique
Ocean energy is a kind of renewable energy sources of containing in the ocean, can be divided into wave energy, tidal energy, energy by ocean current, thermal gradient energy and salt error energy.Wherein wave energy, tidal energy, energy by ocean current belong to fluid mechanical energy, and power generation with marine energy is common exploitation of marine energy process.China has mainland coastline to reach km more than 18000, has more than 6500 large small island, and the island water front always is about km more than 14000, oceanic area more than 470 ten thousand sq-kms, and marine energy resources is very abundant.Wave energy power generation is by wave energy capturing device wave energy to be converted to the reciprocating machine energy, is converted to required electric energy by the power capturing system again.At present existing multiple wave energy technology realizes the wave energy conversion.According to up-to-date in the world mode classification, the wave energy technology is divided into oscillating water column technology, oscillating floater technology and more unrestrained technology.
The wave energy transfer process is the most complicated process in the ocean energy conversion.According to traditional seawave power generation technology, its Main Scientific Issues is: the randomness that (1) wave has causes and can flow unstablely, and the artificer is difficult to determine the design point of wave energy apparatus conversions at different levels; (2) the Multidirectional reciprocating motion of wave makes the artificer be difficult to design rational energy capture system and power capturing system; (3) wave energy apparatus is operated in the place of wave maximum, and the randomness of wave and unstability cause the various sudden seaway load of wave energy apparatus; The burn into marine growth that abominable ocean environment causes adheres to and may cause the inefficacy of some link of device.Therefore, conversion efficiency and the reliability of raising wave energy apparatus are the difficult problems of wave-energy power generation technology.Existing wave energy technology has a common feature: need a medium tache that wave energy is at random converted to stable reciprocating machine energy, this medium tache has mechanical friction, reduce the efficient of wave energy power generation and the reliability of wave-powered generator, improved the cost of system.Because unresolved poor efficiency, low integrity problem, the wave energy technology also is in the stage of fumbling at present, can't the forming device production scale, and cause high manufacturing expense problem.Inefficient, low reliability, these three major obstacles that problem is the wave-energy power generation technology industrialization of high cost.
Summary of the invention
The generating network system that the object of the present invention is to provide a kind of inflating rubber airbag type sea wave power generation machine and form with this rubber pneumatic bag formula ocean wave generator, described rubber pneumatic bag formula ocean wave generator consists of the wave energy grabber by inflatable rubber seal air bag, described wave energy grabber be exactly ocean wave generator directly contact and under the effect of wave, obtain the part of sea wave energy with wave, in the present invention, the wave energy grabber housing parts of ocean wave generator namely: rubber capsule.Described rubber capsule by supporting mechanism assembling by power coil and rolling bearing, central shaft be installed in that pendulum and permanent magnet pole on the central shaft is reciprocity to form machine induced electricity.Described rubber capsule swims in the sea and vibrates with ripple, described pendulum is swung, thereby the permanent magnet pole on the driving central shaft produces relative rotation with power coil, produce induced current, induced current after bridge rectifier and booster circuit boost to output voltage to charge in batteries, so produce the DC electrical source of stable output power, VDC can change industrial-frequency alternating current into after the convertor circuit unsteady flow.Consist of the Wave power generating network network with a plurality of capsule generators like this, can produce powerful electric energy output.This generation mode with wave energy direct-drive power coil need not medium tache, thereby it is little to rub, and efficient is high, cost is low.Described wave energy grabber can be designed to cylindrical body, cuboid, spheroid, ball cone assemblying body, pyramid or other solid of rotation take basic geometrical shape as turning surface.Make in the material of wave energy grabber and strengthen with nylon wire netting, make it to have close to or be similar to intensity and the elasticity of automobile tire, and with the support wave energy grabber of embedded silicon steel sheet web frame.The inflation of described rubber capsule is with the poor shape of keeping of inner and outer air pressure, thereby has preferably elasticity, shock-resistant and collision, and spray opaque plastic film at the rubber capsule towards skyward one side, prevent that the irradiation of sunlight from making capsule aging.Generator and rectification circuit, convertor circuit, charging circuit, storage battery etc. are sealed in capsule, and the direct current that produces is drawn by wire.By being suitable proportion (less than the proportion of seawater) and the center of gravity structure of capsule motor configuration, can be as the floating across the sea to-and-fro motion with the effect of wave the tumbler, thus pendulum is swung and the magnetic line of force and the power coil that drive magnetic pole cuts generating mutually.The magnetoelectricity cutting movement has two kinds of optional design proposals, first central shaft rotatable (being that magnetic pole is rotatable) and power coil is fixed, and it two is that central shaft is fixed (being that magnetic pole is fixed) and power coil is rotatable.As shown in Figure 1, in specified sea areas, single rubber pneumatic bag generator by seabed anchor chain and rack and cable constraint, is formed grid, the inner integrated rectification circuit of air bag generator, boost charge circuit and energy storage battery.The electric energy of energy storage battery is defeated by the unsteady flow in the cabin of diving and the system of confluxing, and the electric current of generating network changes power current into through after the unsteady flow, is transferred to the land electrical network by submarine cable after the transformer transformation in the cabin of diving.Described capsule-type generator is anticorrosive, and anti-collision is not owing to there is the medium tache of mechanical energy transducing, low cost of manufacture, it is little to rub, and generating efficiency is high, the starting of oscillation of wave energy grabber is easy, and the high smaller wave of wave also can make generator produce induced current, thereby is suitable for large-scale industrialization.The moving system of described capsule-type generator only has rolling friction, and the rubber capsule is flexible, and seawater corrosion resistance, and perishable part is sealed in the capsule, kept apart with seawater, thereby long service life.The wave energy grabber that adopts such as the embodiment of the invention is that a lower demifacet is semicircle, and upper half plane is that the plane of isosceles triangle is the ball cone assemblying body that the turning surface rotation forms, and this is a kind of more a kind of than more efficient in the optional shape, but is not only limited to this.The structure of inner power generation part is basic simlarity then.
