The amount of the application for patent in China is very big at present, but actual conversion is very low so that substantial amounts of patent nobody ask Tianjin, or even go out of use, and these patents are actually with very big value, are only possible to slight due to certain point be present The defects of, cause whole patent nobody shows any interest in, really can not be created the wealth for country, therefore, improve existing practical applicability Or conversion ratio is extremely necessary and has an Important Techmical Progress.

The content of the invention

Present invention aim to address the denomination of invention of the present inventor oneself application：A kind of " wind-gathering device " and " one kind gear This two patents of wind apparatus and method and application " are unable to reach the maximization of practical application, the purpose of practicality, solve existing special The problem of sharp actual conversion is low so that real valuable innovation and creation can be on the actual application, so as to be country's wound Make wealth.

It is an object of the invention to improve the deficiencies in the prior art, really solves the vertical axis wind power generation with abat-vent The problem of more than 100 or 150 meters high altitude wind energy resources of the problem of machine maximizes, be altitude, practicality and utilization；It is and vertical Axis wind power generator is when wind speed exceedes design wind speed or brakes during more than work wind speed the problem of, when more than safety During wind speed still can be with normal work problem to the high wind protection problem of blower fan and in super-strong wind-power；The present invention's is another Purpose is the influence for solving the problems, such as to eliminate periodic torque " pulse ", and improves the effect of vertical shaft fan or wind-driven generator simultaneously Rate；Another object of the present invention is when wind-force deficiency, the counter blow water conservancy diversion of wind wheel will be blowed to just aweather position, so as to improve Wind power generator efficiency；Another object of the present invention is after solving installation wind-gathering device or abat-vent, vibrates excessive control dress Direction and the position problems of accurate control wind-gathering device or abat-vent can not be accomplished by putting；Another object of the present invention is that solve The problem of wind-gathering device or abat-vent can be arranged on to 100 meters or more than 150 meters of high-altitude when practical.

The object of the present invention is achieved like this：

A kind of vertical axis aerogenerator with abat-vent, including tower bar, vertical axis rotor or blade, generator system System, abat-vent, support meanss, controller a；It is characterized in that：It is provided with outside vertical shaft fan or wind turbines rotor Keep out the wind object, and the object that keeps out the wind is in support meanss, when wind speed is too low, is moved the object that keeps out the wind by controller Move position before wind wheel, the counter blow for blowing to wind wheel can be stopped or by the counter blow water conservancy diversion to wind by the position The just aweather position of wheel, improves wind speed round, so as to improve generating efficiency；When wind speed is too high, by controller a by the gear Scenery body is moved to position before wind wheel, the position the positive windage for blowing to wind wheel can be blocked or by it is described just aweather Water conservancy diversion reduces the rotating speed of wind wheel, continues to generate electricity not among typhoon or high wind so as to realize to the counter blow position of wind wheel With shutdown.

The wind speed is too low, refers to the wind speed that wind speed requires to formulate less than rated wind speed or according to engineering technology.

The wind speed is too high, refers to the wind speed that wind speed requires to formulate higher than cut-out wind speed or according to engineering technology.

The counter blow, refer to blow to wind wheel, it is the rotating speed for reducing wind wheel that it, which is acted on, hinders wind wheel to do the wind of positive work.

Described just aweather to refer to blow to wind wheel, it is to promote wind wheel to rotate or improve the rotating speed of wind wheel that it, which is acted on, improves wind wheel Do the wind of positive work.

On the abat-vent, controller a, the controller a are installed, are the sizes according to wind direction or wind speed, used To control keep out the wind object rotation direction and the position.

The controller a can include wind speed or/and wind direction measuring instrument, measuring instrument connection sensor, sensor connection Electronic control instrument, according to wind speed or the wind speed or wind direction measured to measuring instrument, sensor passes information to Electronic control instrument, electricity Dynamic controller control support meanss, the object that keeps out the wind is by controller requirement movement or turns to required position and direction.

The controller a, there can be a variety of patterns, every controller that can meet above-mentioned function, all be protected in the present invention Within the scope of.

The object that keeps out the wind, can be arbitrary shape any materials, such as plane, curved face type, flexible material or hard material Material etc.；The object that keeps out the wind, it is that can arbitrarily adjust keep out the wind area or position of keeping out the wind according to the different of wind speed；Or the gear Scenery body, can be one or more.

Preferably, the abat-vent includes two curved surfaces, including wind gathering face and face of keeping out the wind, and described two curved surfaces, is formed One tip angle, the angle is more than zero degree, less than 90 degree.

The abat-vent, because volume or/and weight are very huge, if a system can be produced with common material and technique The problem of row, for example, blow air over come after rock huge, drive whole generator system to rock, control device can not accomplish standard The really direction and position of control abat-vent, therefore, it is impossible to which normal work, brings a series of problem, can not be really achieved Maximization, altitude, practicality purpose.

The wind resource that main wind generator utilizes in the world at present is the height at 20 meters -160 meters, and this is high Degree, and the average height scope of most cities housing-group building, wind-power electricity generation largely consume the wind-force money of this height Source, therefore, the quiet steady weather conditions for easily producing serious haze are formd, therefore, as long as avoiding the wind-force of this altitude range Resource, the wind resource of this height is stopped using, the wind resource for this height of letting pass enters vast hinterland, it is possible to Thoroughly eliminate haze problem.Therefore, in order to reduce haze, it is necessary to by the minimum point of abat-vent, installed in 100 or 150 meters with On height it is aerial, using common material, existing technique is also to accomplish.

It would therefore be desirable to made using special structures and methods.

Preferably, the abat-vent includes housing a, inside or outside the housing a, is provided with obturator, The gas that density is less than air is filled in the obturator, or in the confined space device is low density gas.It is described Low density gas, it is the air that density is less than air.

The density is less than the gas of air, refers to the density of gas of all relative molecular weights less than 29, both less than sky The density of gas, for example, hydrogen, helium, neon, nitrogen, carbon monoxide, methane, hydrogen fluoride, acetylene etc..

Preferably, the arbitrary proportion that hydrogen or helium or neon or nitrogen or the gas are filled in the obturator mixes It is fit.

Most preferably use helium.But in order to reduce cost, hydrogen and nitrogen or hydrogen and helium can also be used Mixed gas, it so can both overcome and the shortcomings that hydrogen is easily ignited is used alone, cost can also be reduced, me can also be reached Application target.

The housing a, can use flexible material, for example, using rubber-like membrane material or Plastic membrane material；Can also Using fiberglass or alloy material or known hard material.

The obturator can use any materials, including flexible material or hard material.

When the obturator uses flexible material, for example, during using rubber-like membrane material or Plastic membrane material, palpus The gas that density is less than air, such as the mixture of helium or hydrogen and nitrogen are filled with inside it；Rubber-like membrane material or modeling Material class membrane material volume will expand, and then seal.The obturator produces upward buoyancy in atmosphere, and the buoyancy is just It can offset or gravity that partial offset housing is downward, so as to reduce the weight of housing, when the obturator volume is sufficiently large, When its caused buoyancy is more than housing downward gravity, the weight of the housing is zero or negative value.In order to reach practicality, Only when housing or/and obturator volume are more than more than 1000 cubic metres, the present invention just has practicality.

When the obturator uses hard material, it has two kinds of selections, you can density is filled with inside it to use Gas less than air produces buoyancy, can also extract the air in its inner space out, form low density gas or vacuum state, The density of the low density gas is less than the density of air, can also produce upward buoyancy, the buoyancy will be offset or part The downward gravity of housing is offset, so as to reduce the weight of housing.Because helium cost is higher, hydrogen is explosive, and therefore, use is thin The advantages of gas is both to reduce cost, solves the problems, such as that hydrogen is explosive again.

The obturator, the inner support body of housing is also used as, when the gas pressure foot in the obturator When enough big, its can substitute completely or part alternative housings inside supporter, so as to reduce support body material.The closed dress Gas no longer leaks after putting exactly sealing.

We are by largely calculating and simulated experiment is drawn a conclusion, when the gas pressure in confined space device is more than During 1.5-2 atmospheric pressure, it can substitute or partly substitute the supporter inside abat-vent completely.

When the obturator uses flexible material, because it can more closely be bonded with the inside of housing, when it During full of pressure, it can closely be fitted on the inwall of housing and highly uniform pressure is formed to inwall, form supporter. The present invention uses confined space device, had both solved the problems, such as that abat-vent weight was big, and had solved asking in volume big structure again Topic.

The support meanss, it is that the object that keeps out the wind can be fixed to support and the object that keeps out the wind can be made to move on demand Dynamic；Or the support meanss, it is that the object stabilization of keeping out the wind can be supported and described one axle of Objects around A that keeps out the wind can be made The device of rotation；The axle can be the central shaft of wind wheel blade；The support meanss, it is that may be mounted at blower fan or wind-force hair In the tower bar of motor, it can also be arranged in other supporting object, such as track supports.

Because large wind-blocking device is very high, any one suffered small wind power of its top, will be produced in bottom One huge torque, when being rocked to solve abat-vent, whole generator system is driven to rock, in abat-vent and support Between device, buffer unit or elastic device are installed, the elastic device can be spring etc.；So that when abat-vent is because of wind When blowing over generation and rocking, there can be a certain degree of Free Slosh, can thus consume a part and shake energy.

Through substantial amounts of theoretical research and verification experimental verification, we have obtained exactly accurate data, when vertical shaft fan is liter During power type blower fan, angle that wind gathering faces the line between the side of nearly wind turbine main shaft and rotor shaft and come between wind direction is During 20-39 degree angle, its water conservancy diversion effect is best, and turbulent flow is minimum,, can be most when wind gathering face is located at this position when wind speed is too low Limits by counter blow water conservancy diversion to just aweather position, it is best to improve generating efficiency；When vertical shaft fan is resistance-type blower fan, The angle that wind gathering faces the line between the side of nearly wind turbine main shaft and rotor shaft and come between wind direction, when spending angle for 0-20, its Water conservancy diversion effect is best, and turbulent flow is minimum,, can be to greatest extent by counter blow when wind gathering face is located at this position when wind speed is low Water conservancy diversion is to just aweather position, raising generating efficiency are best.

Equally, the wind wheel or blade of the vertical axis aerogenerator, it is also desirable to use the special structure of the present invention and side Method makes.

Preferably, the wind wheel or blade include housing b, in the outside or inside of the wind wheel or the housing b of blade, peace Fill or be provided with obturator；The gas that density is less than air is filled in the confined space device, or in the confined air Between be low density gas in device；The low density gas, it is the air that density is less than air.

The housing b, can use flexible material, for example, using rubber-like membrane material or Plastic membrane material；Can also Using fiberglass or alloy material or known hard material.

We are by largely calculating and simulated experiment is drawn a conclusion, when the gas pressure in confined space device is more than During 1.5-2 atmospheric pressure, it can be substituted completely or part substitutes wind wheel or the supporter of blade interior.

In addition, when using large wind-blocking device, the peak of abat-vent is, it is necessary to reach 200 or 300 meters, or even height Up to more than 500 meters, support meanss in any case are all insoluble problem, therefore, this hair all in practical engineering application It is bright in order to solve this problem, take another technical scheme.It is characterized in that by wind wheel or blade, abat-vent, generating Machine is horizontal positioned or uses；Also need to increase controller b, the controller b, the outer rim of abat-vent can be controlled to be aligned all the time Come wind direction, while control the wind wheel or blade and generator and the abat-vent synchronous rotary.The abat-vent Outer rim is the side away from rotor shaft on abat-vent.Support meanss can use known supporting way.Can thus solve to keep off Wind apparatus height problem and instability problem.

The controller b can include wind speed or/and wind direction measuring instrument, measuring instrument connection sensor, sensor connection Electronic control instrument, according to wind speed or the wind speed or wind direction measured to measuring instrument, sensor passes information to Electronic control instrument, electricity Dynamic controller control support meanss, the object that keeps out the wind is by controller requirement movement or turns to required position and direction.

The controller b, there can be a variety of patterns, every controller that can meet above-mentioned function, all be protected in the present invention Within the scope of.The controller b can use same controller with the controller a pooling functions.

The present invention is applied to any type of vertical shaft fan or wind-driven generator, including but not limited to lift-type and/or Resistance force type vertical shaft wind machine or wind-driven generator.

The beneficial effects of the invention are as follows：

The present invention effectively solves the vertical shaft wind with abat-vent in the past by using the method using obturator Power generator is unable to reach maximization and altitude, practicality problem；The object that keeps out the wind, air can be efficiently solved and moved The problem of dynamic braking system, it is also possible to solve wind-force it is excessive when high wind protection problem, no matter great high wind, all may be used The air quantity of wind wheel blade is reached to control as a steady state value, therefore, when running into super high wind can also normal power generation, without stopping Machine；Therefore the present invention, can eliminate the influence of periodic torque " pulse " due to eliminating power pulse caused by counter blow Problem, can also greatly improve wind energy utilization efficiency, and the present invention have found wind guide face and wind by substantial amounts of experimental study The optimum angle angle between line and vertical pivot between wheel shaft, enables wind guide face to play efficiency to greatest extent；This hair It is bright to be also particularly suitable high-altitude wind power generation.
