Abstract

A sealed wheel-bucket type wind-drive electricg generator features that the air drafting channels of building are combined to form a large air drafting unit for driving said electric generator.

Description

The sealed bucket wheel wind power generating set

Technical field

The present invention relates to a kind of high efficiency, powerful wind generating unit.

Background technique

It is little that existing various wind generating unit all exists power, efficient is low, the shortcoming that use value is little, because primary energy day by day reduces petroleum resources and faces exhaustion, oil price will be moved in a high position for a long time, and environment dirt seven, problems such as greenhouse effect, the exploitation and make full use of the reproducible clean energy resource that has a high potential---wind energy, also become very urgent problem.

Summary of the invention

It is big to the objective of the invention is to make a kind of power, the wind power generating set that efficient is high provides a kind of simple in structure, is easy to manufacturing, almost there is not cost of electricity-generating, can be in the rural area, mountain area, outlying district, frontier defense transmission of electricity such as institute, the island stringing difficulty that disappears, the energy shortage area again can be in the north, the wind generating unit that the large, medium and small city of especially windy cold area more can play a significant role.

The critical piece of sealed bucket wheel wind power generating set is:

One, wind guiding tube, the structure of wind guiding tube is constructed very simple shown in figure one, two, surround a horn mouth (Fig. 1) cement pre-fabricated panel both sides with greatly tightly linking iron sheet does top cover with the fixing frame that is connected with ground with iron sheet cement pre-fabricated panel etc. exactly, this horn mouth direction is adjustable, can face wind direction and accept wind-force, large size, the air quantity of large volume puts together and is used, also can be the house, especially building and wind guiding tube constitute jointly one or more typhon mouths as figure two, three, shown in.Because house, especially building itself is exactly the unemployed especially big wall that can keep out the wind, one shotgun house or one, two, or the area of many buildings, volume is very big very big, has mirable huge energy after putting together wind energy, and this just provides free clean energy resource for many generators send powerful electric power.One-storey house, the building overwhelming majority is a Northern Dynasties south, wind, generally mostly be north wind, northwester, and northerly, door generally mostly is face south and opens, wind is at north wall, general family or the sealing of office building window are better, winter is at northern area, especially strong wind period, be that nobody can open a window, the habits and customs that therefore utilize form that one-storey house or building make the air inducing performance in passing and people are without any contradiction, and have brought the very low electric energy family expenses of the electricity charge to these people, especially the heating bathing in winter, brought happiness and money for these people, solved fuel and transportation problem to country, in strong wind period because the energy that wind-force is very big after concentrating is very big, can get up unnecessary electrical power storage, or to grid transmission.

Two, sealing wheel bucket machine (windmill) is as figure, shown in one, four, structure is very simple, and angle steel is done skeleton, and iron sheet is done the wheel bucket, surrounded by the air inducing guide that the half cycle gap is descending to get final product, three faces that air inducing guide three bread enclose the wheel bucket form " the interlock body " of Baltimore grooves and wheel bucket.

Because large-area horn mouth has been arranged, great atmospheric wind and cloud conversion is automatic " being pressed into " wind guiding tube of a large amount of air molecules, volume from large to small, according to Boyle, Robert---boyle's law " gas of certain mass; when temperature-resistant, the pressure of gas is inversely proportional to its volume ", in other words, the few horn mouth of the open-and-shut investment of structure was actually the compressor of an automation originally, and the volume of establishing it is V ₁The time pressure be P ₁, volume is V ₂The time pressure be P ₂, so:

P ₁V ₁＝P ₂V ₂

Distinguished and admirable thus having arrived when sealing the acting of wheel bucket machine, its pressure has increased manyfold, that is to say that wind guiding tube has focused on a focus to the dispersion wind energy of large size large volume, and becomes huge promptly familiar strange " newly " energy.

Because bell-mouthed effect two, force 3 wind just can generate electricity by gear graduation, start one or two, during strong wind, the wind energy after concentrating is very big more than seven or eight grades, by gear-driving speed-variable many generators must be installed, start some machine generatings when wind is big.

The macro-axis (8 among the figure one) of sealing wheel bucket machine (windmill) is installed above ground level half and is taken turns bucket and accept to concentrate back wind-force acting, take turns bucket and drive generator for electricity generation for half below the ground level with driving gear, the generator working room is in the city or the small towns of having a large population and a few land, can be located at underground because strong wind mostly occurs at northern area, and northern severe cold, can be convenient to insulation, reduce capital investment, can reduce surface structures again, save land used.

Three, driving gear and generator because two, the difference of the energy of force 3 wind and seven or eight grades of strong wind is too big, and the rotating speed of generator is fixed, power between them and rotating speed, entirely by the adjusting of driving gear, machine room should someone shine, and regulates.

Embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is done further detail description:

Among Fig. 1 10 is each generator of one of thing, the speedup driving gear 9 of each generator of thing, blower fan macro-axis 8, transmission gearwheel 7, wheel bucket 6.

The direction of arrow indication is wind direction 1, east cement pre-fabricated panel inducing wall 2, West Cement precoated plate inducing wall 3 among Fig. 1, fixedly slotted-angle shelving 4, the air inducing top cover of half garden shape and the skeletal structure 5 of fixing with ground, these five parts of cement pre-fabricated panel just can focus on a focus section to the wind energy of disperseing to two ones of things.Take turns bucket 6, enclosed Baltimore groove of nature formation by wind guiding tube three bread.Though Baltimore groove had formed the very little sealing relationship in gap with the descending half cycle that only surrounded in the gap of wheel bucket before outlet, can contrast the fundamental diagram of four machines of figure, send how many electric weight to what wind energy of copy for the record or for reproduction machine so? is it an invention? this just has to compare with existing wind-driven generator.Existing wind-driven generator does not have wind guiding tube, more do not utilize the house to do wind guiding tube, this is easy to compare, the wind guiding tube structure of this machine can put together large-area wind energy, the blower fan of existing blade type (axial flow), the diameter of blade has only several meters, be example just with 4-6 rice, its garden area has only 12.56---and 28 square metres are more, at least be designed to 20 meters and the horn mouth of this machine is wide, high 10 meters, its area is exactly 200 square metres, be 7 of existing blower fan---15.9 times if utilize the house, especially many buildings keep out the wind and wind guiding tube constitutes jointly oversized horn mouth, may be exactly its more than 100 times or more than 1000 times, the more important thing is its working principle, the wind-driven generator of blade type, its working principle is shown in figure five, it among the figure sectional drawing of blade section, although wind direction is vertical, to on the fairshaped blade shape in an angle α so blade receptible power have only the power of wind speed to multiply by Cos α, that is to say that the distinguished and admirable energy that has has only the sub-fraction energy to give the blade acting, most of energy is that same blade " is brushed past ", go away, blade is not done work, that is to say 12.56---multiply by Cos α again by distinguished and admirable energy in 28 square metres of areas, establishing the energy that has in the garden area of wind-force after blower fan rotates is that the energy that the P blade receives as energy exchanger is W.

That is: W=P Cos α

Have only the sub-fraction wind energy to be utilized, and sealing wheel bucket is pressing under sealing condition, promotes that also the area with regard to the wheel bucket of saying so multiply by wind-force (pressure).Except the air leakage phenomena of only a few is lost a little energy, most energy are being pressed, and on the push boat bucket, the area of establishing the wheel bucket is S, and the pressure of wind-force is P.The gap that the energy W (power) that wheel bucket can receive as the container of energy exchanger deducts 1-2% leaks gas.

Be W=SP--SP2%

So the efficient of sealing wheel bucket machine is more than 90%, most wind energies are utilized, and this is impelled to speak, and this is a great advance! " bucket " of so-called wheel bucket illustrate it is a container, inside can keep watch (atmospheric molecule) is contained in, lack etc. stay a moment kinetic energy go further not late.The exchange of Here it is energy (or power) needs the time, needs " macroscopical displacement " of object.And never be " brushing past ", " going away ".

Because the wind energy that wind guiding tube is concentrated is to have also had 7 of wind-driven generator---15.9 times and 70 times, 700 times.The efficient of wheel bucket machine is more than the twice of blade type engine efficiency, we can say that each power of sealed bucket wheel wind power generating set is more than 20 times to more than 1000 times of existing various each power of wind-driven generator at least.
