Description

Marine power station

The invention belongs to the device that utilizes the ocean wave power to generate electricity.

World today's energy shortage, lack of energy are seriously threatening the mankind.Utilizing nature, develop energy, is the important topic that attracts scientist now.Seawater is being contained huge energy, and people also begin to march to the ocean, allows the huge energy of ocean be human service.Utilize ocean power generation, existing tide power station, ocean temperature differential power device, apparatus for generating electricity by wave force etc.The present invention is the device that utilizes wave power generation.

Wave bounces rocky coast, sends huge boom, the sea beat steamer, and large ship being swayed jolt can not automatic control.According to test, wave reaches the 20-30 ton for every square metre unexpectedly to the impact force of rocky coast, and big person can reach 60 tons.Huge wave can be shifted ten thousand tons of wheels 1700 tons rock upset onto on the bank and go.Utilize the device of the energy generating of wave power, existing imagination or made many kinds, main have fixed apparatus for generating electricity by wave force and a buoy apparatus for generating electricity by wave force.They are the strength of utilizing wave, allow the air of air slide chamber be compressed or expand, and make wave power be converted into flowing of air, are promoted the blade of air turbine machine again by air-flow, make turbo machine produce high speed rotating, drive generator for electricity generation.This electricity generating device power has only about 5KW, can only be as the power supply of navigation mark light on the steamer line and beacon, and maximum device also has only 20KW power.This apparatus for generating electricity by wave force has only utilized the energy of the vertical motion of wave, has promptly only utilized the part of wave power.People also imagined, and improve generated output, will make buoy very greatly, the electricity generating device of a power 3000KW, the external diameter of buoy is wanted 120m, and weight reaches 200 tons, sealing air is very difficult in big like this buoy, can imagine not only heaviness but also be not easy to make of this device.

People have also imagined the device that the energy that can utilize the horizontal motion of wave generates electricity, and promptly utilize the oscillatory wave generating.Such device is the oscillatory wave power generation device.Such as: rotating axle is housed in a keg float, on the axle eccentric wheel is housed, when oscillatory wave rolled keg float, eccentric wheel can drive axle and rotate, thereby drove electric power generation.This still for the device generating efficiency of imagining increases, but power is still very little.

Purpose of the present invention just is to design a kind of high efficiency marine power station, has both utilized vertical wave power of wave, utilizes it to sway wave power again, have the generated output height, build characteristics such as easy, with low cost, can not limited by physical features, use, can be combined into big power station by a plurality of hulls in wide marine site.

A power generation system of the present invention comprises a seagoing vessel and a cover power generating equipment.Power generating equipment is built within the hull of seagoing vessel.Seagoing vessel is with general seagoing vessel appearance similar, but its bottom is the plane, and promptly whole hull is a flat wedge-shape.This shape is convenient to sway under wave stroke and don't is turned over by the top, also is convenient to power generating equipment is installed on the hull bottom.Hull seals water, promptly seagoing vessel above capping is arranged, the power generating equipment of installing in it can not be subjected to the seawater etch, is convenient to M R yet.

Power generating equipment mainly comprises kinetoplast, macro-axis, cranks arm, weighs body, one-way wheel, motor etc.Kinetoplast is suspended on the macro-axis, and holds together with macro-axis, and big axle horizontal is installed on the support that is fixed in hull bottom, and can twist by the fulcrum on support.The installation of cranking arm should be when macro-axis twists, the twisting thereupon of cranking arm also, and the arm end of cranking arm moves up and down thereupon.Heavy body is connected with one-way wheel by connecting rod, and connecting rod is carried on a shoulder pole on the arm end of cranking arm.One-way wheel is only to allow folk prescription to the gear that rotates, it can rotate a fixed position in hull, such as being installed on the gear carrier, when weighing body when a certain direction is moved, one-way wheel is that real wheel can rotate, and when heavy body moved round about, one-way wheel did not rotate for empty wheel, because the effect of heavy body and one-way wheel can be converted into the back and forth movement of both direction unidirectional rotation.

After the assembling of above-mentioned power generating equipment, can when the sea beat hull, under the kinetoplast effect, make the macro-axis twisting, make the heavy body back and forth movement of connecting rod one end by cranking arm, transfer the rotation of one-way wheel again to, drive the rotor rotation at last and generate electricity.

A specific embodiment of the present invention can be referring to Fig. 1.Fig. 1 is a seagoing vessel generalized section of marine power station.Among Fig. 1,1 is hull, and 2 is the hull side board, and 3 is the sea level, and 4 is wave, and 5 for cranking arm, and 6 is macro-axis, and 7 is one-way wheel, 8 bodies of attaching most importance to, and 9 is kinetoplast, and 10 is support, and 11 is speed change gear, and 12 is arrangements for speed regulation, and 13 is motor, and 14 is anchor ring.

Among Fig. 1, support 10 is fixed on the hull bottom, and two ends are respectively established one.6 times suspension kinetoplasts 9 of macro-axis, the two is connected as a single entity.The two end supports of macro-axis 6 can twist around fulcrum on two supports 10.Kinetoplast 9 is big weights, and the material bigger by density constitutes, and its quality size is pressed generated output and the design of seagoing vessel water displacement, should be greater than 1000 tons; Angle was not more than 30 ° and is advisable when the big I of its volume can make hull vacillate now to the left, now to the right according to the distance of hull side board 2 inboard, side to two of kinetoplast 9, can be referring to Fig. 2.Among Fig. 2,2 is the hull side board, and 6 is macro-axis, and 9 is kinetoplast, and 15 is the hull axis, i.e. the line of two ends anchor ring 14, the trunnion shaft when hull 1 sways.Among Fig. 2, the amplitude peak of kinetoplast 9 that dotted line is drawn for swinging, limit by hull side board 2 can not be big again, and concerning hull 1, kinetoplast 9 becomes the power that prevents that it from tilting, making its answer balance again, has just played the effect that prevents that hull 1 top from turning over.

The axle head of macro-axis 6 is horizontally installed with Shape crank arm 5, crank arm 5 the handle and the axle head of macro-axis 6 are fixed, and make that crank arm 5 can be with macro-axis 6 twistings, thereby make 5 two the arm ends motion one on the other with the twisting of macro-axis 6 of cranking arm.

Heavy body 8 the right and left in hull 1 is respectively installed one, and the weight of double body 8 is identical substantially, neglects generated output greatly and decides.Heavy body 8 joins by the irreversible control of connecting rod and one-way wheel 7.Two one-way wheels 7 are only to allow folk prescription to the gear that rotates, and unidirectional wheel shaft is fixed on (gear carrier does not draw among Fig. 1) on the gear carrier, and one-way wheel 7 can rotate around unidirectional wheel shaft.The irreversible control of one-way wheel 7 can be as bicycle very heavy, very heavy function is to pedal forward, when chain was just changeing, flywheel was real shelves, chain drives flywheel and makes the bicycle rear rotation; During the chain counter-rotating, very heavy inoperative, flywheel is a neutral gear, does not drive the trailing wheel of bicycle.The connecting rod that links one-way wheel 7 and heavy body 8 is held up and is placed on 5 the arm end of cranking arm.When two arm ends move one on the other, can alternately hold up connecting rod, make two alternately motions one on the other of heavy body 8.

When heavy body 8 moves upward, one-way wheel 7 does not rotate for empty wheel, when heavy body 8 moves downward (when allowing heavy body 8 move downward during design, move downward by self gravitation), one-way wheel 7 so just is converted into moving up and down of heavy body 8 rotation of the same direction of one-way wheel 7 for real wheel rotates.

In two one-way wheels 7 one is meshed with first driving gear of speed change gear 11, and another is meshed with first driving gear by group's wheel (also claiming reverse wheel).Like this, two heavy bodies 8 alternately move up and down, then first driving gear is all pressed same direction and rotated, and to rotate be (uniform rotation) continuously basically, promptly all have heavy body 8 to make the rotation of first driving gear for power at any one time.Certainly, one-way wheel 7 also can be designed to heavy body 8 and upwards be held up time-out for taking turns in fact, and heavy body 8 is empty wheel when falling.

The wave power of considering the different time wave is strong and weak different, allow motor 13 run well by predetermined rotating speed, with speed change gear 11(can be gear reducer, it also can be pin tooth retarder, with first driving gear is power, rotating speed is increased), arrangements for speed regulation 12(such as centrifugal speed governor) rotating speed of controlling motor 13 closes in the generating requirement, and avoids the fluctuation of voltage and cycle.

After the sea of marine power station launches a ship, two positioning of anchor orientations of hull 1 usefulness, the direction of promptly selecting suitable position and hull 1 to put allows sea beat hull side board 2.Article two, anchor line is installed in the seagoing vessel two ends respectively, determines the position and the direction of hull 1 with the anchor ring 14 that is contained in the outside, hull 2 two ends.Simultaneously, in seagoing vessel swayed, the line of two anchor rings 14 became the axis that sways, i.e. the top of sea beat hull side board 2, and the bottom is the opposite direction swing of axial sea beat with the line of two anchor rings 14.In order to increase the arm of force of wave power, anchor ring 14 can be opened between macro-axis 6 and sea level 3, is 1 apart from the two the ratio of vertical distance: 2-1: 4.The reason wave is excessive and turn on the top to consider hull 1, in design and when location, should make hull 1 capping exceed sea level 4-5.5 rice and be advisable.When building, seagoing vessel also should consider equipment and facilities such as draining, ventilation, gateway, anchor line elevator.

Another embodiment of the present invention is, will be designed to two-layer ship storehouse in the hull 1, and flat one deck installs kinetoplast 9, support 10, heavy body 8, crank arm 5, macro-axis 6, one-way wheel 7 etc.Design is equipped with speed change gear 11, arrangements for speed regulation 12, motor 13 etc. on the plane at two anchor rings, 14 places at the bottom of the storehouse, storehouse, upper strata.5 centres that are installed in macro-axis 6 of cranking arm, all the other equipment are by the last embodiment installation of joining.This embodiment's seagoing vessel stablizing effect is good, and motor 13 also only is subjected to quite little swaying.

It is big that marine power station of the present invention has power, the advantage that cost is low: wave power generation does not need to make the dam, burn coal, thereby very big investment and the spending of saving, under identical cost condition (a plurality of hull combination), generated output can be 50-100 times of water power plant, the generated output of each seagoing vessel can be at 2000KW-20000KW, the hull of marine power station does not need the extra-fine steel material, kinetoplast also only needs weight big, and high cost material not, without underwater operation, therefore whole cost is just very cheap during construction, compares with the three gorges hydropower plant, when generated output is identical, has only about 1/100 of the three gorges hydropower plant investment.Seagoing vessel volume of the present invention is little, compares with 3000KW power buoy apparatus for generating electricity by wave force, and be the 1/2-1/4 of buoy only, and buoy will be to aeroseal, and seagoing vessel is only to water seal, can be at land formation as hull, involved in evil-doing easily with positioning and directing and settled, therefore built easily.The present invention can also arbitrarily make, because the marine site is wide, can arbitrarily settle seagoing vessel of the present invention, can make up by many ships, can not limited by sub sea conditions, as long as seabed depth is higher slightly than the main body of hull, also can be the steamer power supply of island and oceangoing voyage easily.Design principle of the present invention is reliable, rational in infrastructure, only require the steel of the hull outside with anti-seawater corrosion, and the power generating equipment in it is not subjected to the seawater etch, and these provide convenience all for maintenance, maintenance, also can use for a long time.The present invention overcome wind-power electricity generation off and on, shortcoming that power is little, overcome the shortcoming that the hydroelectric power investment is high, destroy the ecological balance, land occupation, overcome the shortcoming that thermal power generation consumes coal, befouling environment, be a kind of desirable electricity generating device.The present invention can produce in batches, the wound substantial economics.The water of rivers is always exhausted, and underground coal is always dug dried, and the ocean wave power is inexhaustible, the nexhaustible energy, so marine power station of the present invention will be coming.
