One, technical field

The present invention relates to a kind of wind-power electricity generation and produce the device of hydrogen, particularly a kind ofly use arc toothed chaindriven wind-power electricity generation hydrogen-generator with environmental protection effect.

Two, background technique

" chain-driven design and the application manual " published " chain-driven " that " circular tooth gear " that China Machine Press publishes in March, 1980, in December, 1984 publish and in September, 1992 introduced the superiority and the various chaindriven structure and feature of circular tooth gear respectively." generation of electricity by new energy " book of nineteen eighty-two publication has been introduced the structure and the working principle of 12 kinds of wind turbines, and its common drawback is a complex structure, the cost height, and rotating speed is slow, does not have economic competitiveness.

The present invention combines circular tooth gear and chaindriven technology essential factor and forms arc toothed chain, and blade is installed on chain, wind energy be converted into electric energy and and then decomposition water make the device of hydrogen.

Three, summary of the invention

For solving the problems of the technologies described above, technological scheme of the present invention is: gear transmission is the gear teeth that push follower by the gear teeth of driving wheel successively, to realize transmitting movement and power.Gear transmission develops into involute gear by cycloidal gear, develops into circular tooth gear at last again.The characteristics of circular tooth gear are that the flank of tooth of two engaging gears is double wedge flank profil and recessed tooth flank profil, and the recessed tooth during engagement encases double wedge, to improve its contact strength.The radius of arc of convex-concave flank profil equates, so just can obtain the instantaneous line contact along whole tooth depth, and the circular tooth gear transmission is protruding, recessed flank of tooth contact, and the contact area moves along facewidth direction with quite high Rolling velocity.In the circular tooth gear transmission, Sliding velocity is lower in addition, and friction loss is less.

Chain-driven is a kind of engagement driving with middle flexible element, can do transmission with, carry usefulness, drag draw promote with and many structures special special purpose of performance cleverly.It has some characteristics of gear transmission and band transmission concurrently.Since it have simple in structure, power transmission is big, efficient is high, velocity ratio is accurate, maintains main features such as easy.Chain-driven mainly contains bush roller chain and silent chain, and roller chain has the small roller of rolling, and force of rolling friction is less, and the noiseless transmission speed of silent chain is bigger, but is easy to rupture in the middle of carrier bar.

Comprehensive above each basic fundamental key element, form the feature of arc toothed chain: the sprocket wheel pitch circle is divided into the 2N five equilibrium, make 2N tangent circle, adjacent circle stays one to go one, the N that stays circle is sprocket tooth form, sprocket wheel basic structure is at rotatingshaft two ends fastening flange, and each flange respectively bores N hole, N cylindrical body is installed is formed sprocket tooth.Chain and chain-plate is six sections circular arcs compositions doing the basis with the contacted cylindrical body of sprocket tooth.The sprocket of this structure and sprocket wheel are fitted closely, improved contact strength, chain tooth root section is generous, has improved the intensity that fractures, it is little to slide between the flank of tooth during transmission, rolling friction has reduced wearing and tearing, has improved efficient, and flank profil is a circular arc, simple shape, be convenient to make, reduce cost, and reach higher precision easily.

The basic structure of wind chain turbine is: rotatingshaft is installed on fixed support, travel(l)ing rest is installed on rotatingshaft, travel(l)ing rest and fixed support have a common fixed bias circuit, the movable axis of available bolt roll adjustment is installed at the other end of travel(l)ing rest, two pairs of sprocket wheels of corresponding respectively installation on stationary axle and movable axis, two arc toothed chains are installed on sprocket wheel, between two chains blade is installed, blade is fixed-site on one side, another side can be swung within the specific limits, the angle of swing is to less on one side, and is bigger to another side.The low speed blade can adopt film type, and the high speed blade can adopt streamlined.Blade is installed on the chain in turn, Yi Bian wind is from blowing to blade, Yi Bian blade is motionless, another side is moved by wind, will open a less angle, forms a narrow slit, air-flow is compressed with big speed and sprays from R-joining, drive chain movement at air-flow recoil force effect lower blade, air-flow continues motion, rushes at the another side blade, push bigger angle open, airspeed slows down, kinetic energy diminishes, and the kinetic energy that has reduced is converted into the motion that blade drives chain.The orientation that the antithesis moment of two chains is converted into sprocket wheel rotatablely moves.Air stream impacts blade twice, and Wind Power Utilization efficient is higher.When wind when other direction blows to blade, the angle of both sides blade all will change direction, but the vane stress direction do not become, sprocket wheel still rotates to former direction, the wind sprocket wheel machine that different direction is placed combines and just can omit adjusted device to same direction rotation.Three kinds of methods are adopted in the speed governing of wind chain turbine: 1, increase the load speed governing; 2, change the speed governing of travel(l)ing rest angle; 3, come speed governing with clutch increase and decrease association number.Wind chain turbine can utilize the wind of ground disorder, using near ground, is convenient to installation, maintenance and operation.Wind chain turbine features simple structure, manufacturing is easy, does not have big process component, and bigger parts all are former blanks, what widely apply in addition is existing standard piece, wind chain turbine requires not strict to raw material, can gather materials on the spot, and utilizes landform, atural object can save raw material, blade can utilize the waste and old processing film of warmhouse booth to form, because blade is swing automatically, the pendulum angle size is controlled by wind speed, and wind chain turbine is kept substantially than stable rotating speed.While travel(l)ing rest changeable angle, thus blowing area changed, the rotating speed and the power of control wind chain turbine.Can also increase and decrease the number of wind sprocket wheel machine combination in addition with clutch, control rotating speed and power.Rotatablely moving of this variable-speed can be used to the drawing generator generating.Existing wind-power electricity generation mode, small-sized employing DC generator, large-scale employing alternator.AC and DC mixed power generation mode is adopted in the generating of wind chain turbine.In the time reaching rated speed and power, use alternator to generate electricity by way of merging two or more grid systems.The part that does not reach rated speed or exceed rated power adopts DC generator.Generator can be used the homopolarity DC generator, and the low-voltage, high-current direct current that sends can obtain hydrogen with the electrolytic bath decomposition water, and water electrolysis hydrogen production is a kind of mature technology.Brine electrolysis will consume a large amount of electric energy.Existing electric energy major part is from coal fired thermal power plant, and brine electrolysis efficient is not high, makes that the cost of hydrogen manufacturing is very high, because economic cause has limited its application.The generating of wind chain turbine is free wind energy owing to what utilize, especially utilizes the unavailable that part of energy of alternator to produce hydrogen, can obtain to have the free of contamination fuel and the industrial chemicals of environment protection effect.

Arc toothed chain type wind chain turbine, realization wind energy and mechanical energy conversion need be installed blade on chain, and on chain, blade edge is tree lace fixedly, is fixed on screw on the back carrier bar of chain with fixed by nut for the vanes fixed screw mandrel of trapezoid blade.

Arc toothed chain type high speed winds chain turbine is that streamlined spring leaf is installed on second kind of six sections circular arc carrier bar with the vanes fixed screw mandrel, and leaf baffle screw mandrel, blade stop that oppositely screw mandrel controls the stressed inclination angle of blade respectively.

Compared with prior art, the invention has the beneficial effects as follows: use Transmitted chains and carry the blade rotation sprocket wheel,,, simplified speed change gear so its rotating speed is very fast because sprocket diameter is more much smaller than aerofoil profile rotating diameter.Sprocket wheel is a builtup member, wearing and tearing can be changed later, save maintenance expenses, because arc toothed chain structure is easy, the not only available steel plate stamped of the carrier bar of chain, also available engineering plastics, glass and pottery are made simultaneously, enlarged the raw material source, easy processing does not have big processing component simultaneously, application standard spare as far as possible, coupling, universal joint, cone gear, clutch and bearing etc. are all selected existing product for use.Utilize terrain and its features can reduce raw materials consumption, reduce cost, it can utilize the wind work of ground disorder, does not need tall and big support, makes closely face of wind chain turbine, and not only installation, maintenance and use are all carried out on ground, and greatly reduce the wind speed on ground.The harm of wind sand all is that surface wind causes, if can reduce the ground wind speed utilize wind chain turbine to generate electricity on a large scale near ground, stops the sand dune to be moved, and alleviates sandstorm harm.China is corroded by dust storm every year, and tract is desertified.Utilize technological means not only can slow down desertification speed, obtain mechanical energy simultaneously and electric energy is used for pumping irrigation, will speed up the process of administering dust storm again.Wind chain turbine reduces the ground wind speed in the course of the work in addition, and the crops in farmland are also played a kind of protective action, and is the same with in the past windmill, can irrigate during arid, but draining during flood.Wind chain turbine is not only Conversion of energy equipment, and being both also is environment protection equipment.It can become energy base to the sources of sandstorms of harm soil economic value, the source of creating the wealth.

Five, embodiment

Steel chain mixes application with engineering plastics, glass, ceramic chain.Arc toothed chain is because carrier bar is generous, if use steel plate stamped cost inevitable very high entirely.Engineering plastics, toughened glass, stupalith are convenient to make, and be more wear-resisting, if be used with the steel carrier bar, just can bring into play advantage separately and reduce production costs.

The meaning of rural area, grassland, desert wind-power electricity generation.Wind energy is present in vast nature, and it is the energy in rural area.Because arc toothed chain type wind chain turbine features simple structure, general township enterprise can make and install, and common peasant can Operation and maintenance.Utilize it to alleviate the manual labor of oneself, solve life, reduce the loss of natural disaster, preserve the ecological environment with energy.In addition, a large amount of mechanical energy, electric energy and Hydrogen Energy also are the base substance conditions to the degree of depth of producing and range development, be the new means of labour of farmer richness, use wind energy in vast pastoral area equally, also can play promotion and produce, prevent the effect of desertifying in the grassland.Use the generating of wind chain turbine in sources of sandstorms, can reduce wind speed, alleviate the harm of sandstorm.

Air-flow run into massif will on lift the change direction, flow along the hillside, so will strengthen on top, hillside and mountain top wind speed.Wind speed doubles, and power is the octuple of former power, and the wind chain turbine of same blowing area is installed on hillside and mountain top, not only can save material, reduces cost, and can improve power greatly simultaneously.The principal element of restriction mountain area economy development just is lack of water.The mechanical energy of utilizing wind chain turbine to be obtained is sent to eminence with water from lower, will promote the development of mountain area economy greatly, the dykes and dams high on the riverbank have compressed air-flow, have strengthened wind speed, wind chain turbine is installed on the riverbank, and the mechanical energy that is obtained can be used to build dykes and dams and cleaning riverway sludge.

China is the country on mountain more than, forms many huge mountain passes between many tall and big mountain ranges.Mountain pass wind-force has two characteristics, and the one, wind speed is bigger, and the 2nd, air-flow flows along the mountain pass direction, so the wind direction major part all is positive and negative both direction, this character is particularly suitable for building large-scale wind sprocket wheel machine power generating system.China Qinghai-Tibet Platean, mountain range are east-west mostly, and west wind is often blowed along the mountain valley in Tibet.All there are many big mountain passes in Tibet, Xinjiang, in addition, between the numerous mountains mountain range of east, Liaoning and hills, the west of Liaoning, vast loose distant Plain is arranged, often blow south wind or southerly, north wind or northerly, seldom The wind blew east and west wind, wind speed has been strengthened as jet pipe in these areas, is fit to very much use wind chain turbine exploitation wind energy.

China's southeastern coast is endangered by typhoon all will every year, causes very big loss.Wind turbine in the past is because blade is huge, and blade has the danger that is fractureed in strong wind, and wind chain turbine blade area is less, adopt streamline vane, can in strong wind, move, wind energy transformation is the useful energy form after, wind speed has just reduced, and has also just alleviated the disaster of typhoon simultaneously.The streamline vane number is less, like this could be in strong wind the pressure of wind-engaging less, the energy safe operation, the fixedly screw mandrel of streamlined spring leaf is installed on second kind of six sections circular arc carrier bar, screw mandrel is also installed in two other hole of carrier bar, and when wind blowed to blade from the outside, blade was stopped by screw mandrel, because the screw mandrel distance is bigger, the angle that blade forms is less.When chain takes blade to another side, air-flow will continue the compressing blade and since the vanes fixed screw mandrel with stop that oppositely the screw mandrel distance is less, the angle that blade forms is bigger, according to the gas dynamics principle, wind chain turbine has obtained the power of rotation.

The characteristics of wind energy and other renewable energy sourcess are exactly that energy density is lower, utilize equipment huge, and material is more, and cost is higher.Renewable energy sources exploitation is at present restricted by economic condition seldom mainly.In order to break away from this predicament, multiple renewable energy sources is developed jointly utilization, bring into play the advantage of the various energy, reduce cost, in associating, each doing his best, for society creates the wealth, renewable energy sources is developed jointly can adopt following form: water can be used arc toothed chain turbine with ocean energy and wind energy and be converted into mechanical energy, further is converted into electric energy and Hydrogen Energy again.A large amount of mechanical energy is used to start heat pump, solar thermal energy and geothermal power are moved to the temperature higher position from the temperature lower, and this just obtains a large amount of high temperature heat.Wind energy, water energy and ocean energy are converted into mechanical energy, the drive shredder adds water and adds the saccharification of strong acid heating hydrolysis after crop stalk is pulverized, and produces alcohol fuel through alcoholic fermentation then, vinasse are used for stock raising, and ight soil is produced biogas through high-temperature anaerobic fermentation.
