Along with Chinese society and rapid economy development, power consumption is increasing, the coastal region in east China particularly, and the electricity consumption volume hits new peak especially repeatly during the broiling summer, power supply day is becoming tight, and electricity shortage becomes the key factor of the restriction national economic development and social life raising.And China shore line is very long, the morning and evening tides that is richly stored with, the hypo energy, the only way that therefore to further investigate morning and evening tides, hypo generation technology be the development of new energy, solve the power shortage problem.Traditional hydroelectric power mostly is the form in water power plant, by building dam, utilizes the height of water to impact the electricity generating device of below, and potential energy converting and energy is become huge electric energy.But can utilize the physical features of this drop and few, and build a water power plant and will spend huge manpower financial capacity, it also endures dispute to the fullest extent to the influence that physical environment causes.Tidal power generation is a kind of new forms of electricity generation, and the water-head of utilizing the high tide ebb tide to be produced is generated electricity, and the potential energy converting and energy of seawater is become electric energy.But utilize tidal power generation must possess two geographical conditions at present: at first the amplitude of morning and evening tides must be big, will have several meters at least; Second coastal landform must can be saved a large amount of seawater, and can carry out civil works.The requirement of this two aspect has limited the development of large-scale tide power station, makes tidal energy fail to be utilized efficiently.
The wave wave energy of ocean also is a kind of good energy, and the seawater potential energy that can utilize the hypo fluctuating to form carries out the hypo generating.Shore line, Deposits in Eastern Coastal China area is very long, and seawater is all the time all in fluctuation, makes novel hypo generator for electricity generation thereby develop the energy that this seawater fluctuation produced, and is a kind of effective utilization of new energy resources means.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of and utilizes the seawater fluctuation, by buoy and ball guide screw nat in conjunction with the novel electricity generator that carries out the hypo generating, simple in structure, volume is small and exquisite, cheap, especially can carry out whole day uninterruptable power generation work, be adapted at coastal waters and be extensive use of.
The scheme that is provided is provided the utility model: a kind of buoy ball screw combined type hypo generator comprises: a buoy, and wherein the buoy internal fixation has the generator unit stator winding; One ball guide screw nat, wherein ball screw passes buoy and exposes the sea, and nut is placed in the buoy; One stationary axle is fixed on the sea bed; Spring-backed quill and spring-backed quill once can stretch and compress on one; One transmission of electricity cable, the output electric energy.The ball screw of ball screw pair passes buoy along the central shaft position of buoy internal stator winding, the ball screw upper end of ball screw pair is passed buoy and is exposed the sea level, fixedly connected with stationary axle in the ball screw lower end of ball screw pair, the nut periphery of ball screw pair is installed the p-m rotor magnetic sheet, last spring-backed quill and following spring-backed quill are wrapped in the ball screw outside, and be tightly connected with the buoy opening, the stationary axle lower end is fixed on the sea bed by base, and the transmission of electricity cable is guided to below the sea bed of stationary axle lower end after buoy picks out on the bank in the transformation device again.Particularly, this buoy ball screw combined type hypo generator is placed on coastal shallow water marine site, buoy is across the sea floating, and the fluctuating along with hypo under the action of gravity of the buoyancy of hypo and himself and interior arrangement moves up and down; The ball screw of buoy outside is avoided being corroded by sewater chemistry by last spring-backed quill and following spring-backed quill environmental sealing; The nut of buoy inside is with respect to power coil staor winding axial restraint; Ball screw is fixedlyed connected with stationary axle, the kinetic energy of hypo changes into the rotation function of nut by buoy and ball screw pair, the nut p-m rotor is done the cutting magnetic induction line motion and is generated electricity in the stator coil inner rotation, exports electric energy through the lead that stator coil is drawn by cable.Described ball screw length is greater than the local marine site maximum difference of wave trough height when wave crest height and ebb tide at the incoming tide, and guarantees can not hinder buoy fluctuating with hypo because of the contraction of last spring-backed quill and following spring-backed quill.
Appropriate location, the inner generator unit stator winding both sides of buoy can be mounted with bearing (ball) cover; place bearing in the bearing (ball) cover of the inner generator unit stator winding of buoy both sides; it is rotated flexibly; bearing type is the tapered roller bearing or the deep groove ball bearing that can bear axial force; the nut of ball screw pair is placed in the middle of the bearing, and the nut of ball screw pair carries out axially locating by bearing.
Buoy and last spring-backed quill and following spring-backed quill and to go up spring-backed quill and following spring-backed quill and being connected of ball screw available bonding or tie up connection.
Described buoy profile is under the situation that guarantees the generator proper functioning, and the concrete structure of described buoy ball screw combined type hypo generator can have various ways, can carry out innovative design according to requirement attractive in appearance.The lead of drawing from stator coil connects the transmission of electricity cable, cable can be embedded in the seabed, and connection transformation device on the bank is to mains supply then.
Described buoy adopts macromolecular material rotationally molding or blow moulding and forming, or by bonding forming such as metallic material, polymer-based multilayer materials, timber, or by sheetmetal, macromolecule diaphragm through being welded, processing is simple, cost is low, anti-aging, not fragile.
