The problem of row, for example, rocking huge after blowing air over, drives whole generator system to rock, and control device can not accomplish standard
The direction and position of abat-vent are really controlled, therefore, it is impossible to normal work, brings a series of problem, it is impossible to be really achieved
Maximization, altitude, practicality purpose.
The wind resource that main wind generator is utilized in the world at present is the height at 20 meters -160 meters, and this is high
Degree, is also the average height scope of most cities housing-group building, the substantial amounts of wind-force money for consuming this height of wind-power electricity generation
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, stops using the wind resource of this height, and the wind resource of 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 be made using special structures and methods.
Preferably, the abat-vent includes housing a, inside or outside the housing a, is provided with obturator,
Gas of the density less than air is filled in the obturator, or is low density gas in the confined space device.It is described
Low density gas, is air of the density less than air.
The density, less than the gas of air, refers to the density of gas of all relative molecular weights less than 29, both less than empty
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 is mixed
It is fit.
Most preferably use helium.But for reduces cost, it is also possible to use hydrogen and nitrogen or hydrogen and helium
Mixed gas, so can both overcome and the shortcoming that hydrogen is easily ignited had been used alone, can be with reduces cost, it is also possible to reach me
Application target.
The housing a, can use flexible material, for example, using rubber-like membrane material or Plastic membrane material；Can also

The mixture of gas of the density less than air, such as helium or hydrogen and nitrogen is 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
Can offset or the downward gravity of partial offset housing, so that the weight of housing is reduced, when the obturator volume is sufficiently large,
When buoyancy produced by it 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, it is also possible to extract the air in its inner space out, forms low density gas or vacuum state,
Density of the density of the low density gas less than air, it is also possible to produce the upward buoyancy, the buoyancy will to offset or part
The downward gravity of housing is offset, so as to reduce the weight of housing.Because helium is relatively costly, hydrogen is explosive, therefore, using thin
The advantage of gas is both to reduce cost, solves the problems, such as that hydrogen is explosive again.
The obturator, is also used as the inner support body of housing, 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 drawn a conclusion by substantial amounts of calculating and simulated experiment, 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 fit with the inside of housing, when it
During full of pressure, 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, has both solved the problems, such as that abat-vent weight was big, and asking in volume big structure is solved again

The device of rotation；The axle can be the central shaft of wind wheel blade；The support meanss, can be to be sent out installed in blower fan or wind-force
On the tower bar of motor, it is also possible in other supporting object, such as track support.
Because large wind-blocking device is very high, suffered any one the small wind power in its top will be produced in bottom
One huge torque, when being rocked to solve abat-vent, drives whole generator system 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, the angle that wind gathering faces the line between the side of nearly wind turbine main shaft and rotor shaft and comes between wind direction is
During 20-39 degree angle, preferably, turbulent flow is minimum for its water conservancy diversion effect, when wind speed is too low, when wind gathering face is located at this position, and can be most
Limits by counter blow water conservancy diversion to just aweather position, improve generating efficiency is best；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 comes between wind direction, when being 0-20 degree angle, its
Preferably, turbulent flow is minimum for water conservancy diversion effect, when wind speed is low, when wind gathering face is located at this position, and can to greatest extent by counter blow
Water conservancy diversion is to just aweather position, and improve generating efficiency is best.
