Preferably, described wind gathering face is that periphery is low, and middle high convex structure makes impeller of blower be positioned at the neutral position, so just can make the wind from any direction can reach the effect that increases air quantity.
Preferably, the present invention is by upper and lower two wind gathering faces, and support described two faces and make it one or more firm pillars and constitute, distance between two wind gathering faces, have at least on one side greater than another side, when the direction of wind when the direction on the big one side of distance blows to the little one side of distance, described two wind gathering faces will make to assemble by the wind of fan blade upper and lower and come, increase air quantity, thereby improve the efficient of blower fan.
Preferably, the distance between upper and lower two the wind gathering faces of the present invention, peripheral position blows over can make the air quantity of intermediate portion to increase when wind from any direction greater than the intermediate portion, makes fan blade be positioned at the zone, intermediate portion, thereby improves the efficient of blower fan.
Preferably, wind gathering face of the present invention is provided with the wind guiding gutter, and the effect of described wind guiding gutter is that the wind direction intermediate portion of periphery is gathered.
Wind gathering face of the present invention and pillar can be can making described shape and keeping firm material to constitute of metallic material or Reinforced Concrete Materials or any known.
Pillar of the present invention also can be can supporting described wind gathering face and making the firm device of described wind gathering face of support or any known.
The present invention is applicable to various blower fans and wind power plant.
The present invention can use one or one with fan or wind power plant simultaneously.
The present invention can improve fan efficiency, thereby improves generating efficiency.
Wind gathering face of the present invention is parallel to ground level and places.
A kind of technological scheme that increases the device of air quantity raising blower fan or wind power generator efficiency of the present invention is, a kind of device that increases air quantity raising blower fan or wind power generator efficiency, it is characterized in that: it is made of one or more one or more wind gathering faces of shore supports, and at least one limit of described wind gathering face is higher or lower than another limit.
Preferably, described wind gathering face is that periphery is high, middle low concave structure, or the low convex structure of middle high periphery.
Preferably, the present invention is by upper and lower two wind gathering faces, and one or more pillars that support described two wind gathering faces constitute, and the distance between two wind gathering faces has at least on one side greater than another side.
Preferably, the distance between upper and lower two the wind gathering faces of the present invention, peripheral position is greater than the intermediate portion.
The present invention also comprises one or more blower fans or wind-driven generator, and the position of blower fan or blade of wind-driven generator is positioned at the air quantity maximum position that described increase air quantity improves the device of fan efficiency.
The invention has the beneficial effects as follows:
The present invention can be on the basis of existing wind energy turbine set, slightly increase some input seldom, just can improve the efficient of wind-power electricity generation greatly, particularly for high-power unit, every raising is power little by little, all mean the lifting significantly of cost and technical difficulty, in theory, the present invention can be with upper and lower two infinities that wind gathering face is done, thereby power that can infinitely-great raising wind-power electricity generation is from actual, the present invention also can increase exponentially generated output under the constant situation of blower fan or wind turbine equipment.The present invention can also protect blower fan or wind turbine equipment effectively, makes it to avoid the erosion of wind and rain, thereby improves the working life of blower fan or wind turbine equipment.
