A kind of blower fan wind wheel or blade with length extension device, including at least one wind mill wind wheel or blade, it is characterized in that,
There is at least one length extension device on the wind wheel or blade, inside or outside the length extension device, install or be provided with
Confined space device；Gas of the density less than air is filled in the confined space device, or in the confined space device
It is inside rarefied air.
The length extension device, can use any materials, including flexible material or hard material.
The length extension device, including housing and inside confined space device.
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, any ratio of hydrogen or helium or neon or nitrogen or the gas is filled in the confined space device
Example mixture.
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 confined space device can use any materials, including flexible material or hard material.
When the confined space device uses flexible material, for example, using rubber-like membrane material or Plastic membrane material
When, the mixture of gas of the density less than air, such as helium or hydrogen and nitrogen must be filled with inside it；Rubber-like membrane material
Or Plastic membrane material volume will expand, and then seal.The confined space device produces upward buoyancy, institute in atmosphere
Stating buoyancy will offset or the downward gravity of the whole length extension device of partial offset, so that the weight of length extension device is reduced, when described
When confined space device volume is sufficiently large, when the buoyancy produced by it is more than length extension device downward gravity, the length extension device
Weight be zero or negative value.So can increase the diameter of wind wheel or the length of blade, it is also possible to mitigate overall wind wheel
Weight.
When the confined space device uses hard material, it has two kinds of selections, you can be filled with inside it with using
Density produces buoyancy less than the gas of air, it is also possible to extract the air in its inner space out, forms low density gas, Ye Ji
It is internally formed vacuum state, it is also possible to produce upward buoyancy, the buoyancy will offset or partial offset length extension device to
Under gravity, so as to reduce the weight of wind wheel or blade.
When the gas pressure in the confined space device is sufficiently large, it can be substituted completely or part substitutes and lengthens dress
The supporter of inside is put, so as to reduce support body material, length extension device weight in itself is reduced.
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 length extension device completely.
The confined space device can also be the length extension device housing in itself, in the enclosure interior, set certain
Region, the gas full of density less than air, then seals.
