Abstract
The utility model relates to a wind power electricity generating blower fan with sail-shaped blades, comprising sail-shaped blades, a main shaft, an upright post, etc. The sail-shaped blades which have a movable type and a fixed type can be directly installed on the main shaft of the blower fan and can also be installed on a driving ring composed of a chain and chain wheels. The biggest advantage of the blades is that the wind receiving faces are big, so that the wind energy can utilized furthest. The utility model has the advantages of simple structure, convenient use, and low investment.
Description
The utility model relates to a kind of sail shape wind-power electricity generation blower fan.
Wind-driven generator generally partly is made up of blower fan and generator two.The blade of existing domestic and international wind-power electricity generation blower fan generally is the strip blade with certain helix angle, and its structure is simpler, and manufacturing is easier to, and uses, changes also very convenient.But it is little that it accepts the area of air quantity, utilizes wind-force limited.
The purpose of this utility model is the deficiency at above-mentioned technology, and provides a kind of wind-receiving face big, can make full use of the sail type wind-power electricity generation blower fan of wind energy.
The utility model is achieved in that its maximum feature is that blade is a sail shape blade, thereby more traditional blade has increased the air quantity of accepting exponentially, has maximally utilised wind-force.
A kind of sail shape blade is made of the movable sail shape blade that can uphold and shrink framework, flexible sail face, weight.
Sail shape blade is contained on the main shaft, end at the close main shaft of blade has a weight 2 that slides along the main shaft Vertical direction at least, when blade during over against wind, under the effect of weight, the sail face can be opened to greatest extent, and contrary during to wind direction when the sail face, under the effect of weight, the sail face shrinks to greatest extent.Sail shape blade also can be fixed on the chain, and main shaft and sprocket wheel are fixedly connected, and utilizes weight to uphold equally and shrinks the sail face.
Sail shape blade is hinged on the chain, and main shaft and sprocket wheel are fixedly connected, and between chain and the sail shape blade positioning block is arranged, when sail face during over against wind direction, the positioning block supporting blade is in erectility, when the sail face contrary during to wind direction, positioning block does not play supporting role, and blade is swung to chain along the hinged place.
Fig. 1 is that movable sail shape blade is contained in the schematic representation on the main shaft.
Fig. 2 is the blower fan part plan view of Fig. 1.
Fig. 3 is that movable sail shape blade is contained in the schematic representation on the chain.
Fig. 4 is contained in schematic representation on the chain for fixing sail shape blade.
Now illustrate in detail with regard to structure of the present utility model and working principle in conjunction with the accompanying drawings:
Blade 1 constitutes sail shape blade by frame 11 and flexible material 12, be bearing in to symmetry properties on the main shaft 6, when blade is in the top position of vertical major 6, weight 2 on it slides to the bottom of blade automatically on slideway or axle, this moment, blade was the sail shape of extension, its area maximum, and over against wind direction, blowing area is also maximum, and the wind-force of acceptance is also maximum.When blade when main shaft is rotated down, weight 2 slides to the top of blade automatically by its gravity and action of centrifugal force, and blade is the sail shape of contraction, and the wind-force of its blowing area and acceptance is more and more littler, be minimum when being in the vertical position of main shaft 6 bottoms, this moment, blade was in state against the wind.Blade is made up of multi-disc, is distributed in symmetrically on the main shaft 6, because the effect of wind-force, they ceaselessly rotate with main shaft, contract when opening during blade, goes round and begins again, and main shaft 6 drives generator 4 work by driving mechanism.This blade can also be contained on the chain 8, utilizes wind-drive chain 8, and chain 8 is driving sprocket wheel 9, main shaft 6 again, drives generator work through gear again.
Another kind of sail shape blade is made all-in-one-piece (being that sail shape blade can not uphold and shrink) by metallic material or plastics, it is hinged on the chain 8, main shaft 6 is fixedly connected with sprocket wheel 9, positioning block 10 is arranged on chain 8 or blade, chain cooperates with sprocket wheel (chain is to arrange chains or many chains more, sprocket wheel adapts with it), when blade 1 is in the top of chain, blade 1 is over against wind direction, positioning block 10 is in the reverse side of blade wind-receiving face, supporting sail shape blade roughly is in the vertical surface of chain, because the effect of wind-force forces chain 8 to drive sprocket wheel 9 rotations, and drive generator 4 generatings through driving mechanism, when blade movement during to the below of sprocket wheel 9, the wind-receiving face of blade 1 is opposite when being in sprocket wheel 9 tops, positioning block does not play supporting role, blade 1 rotates around the hinged place, until pressing close to chain 8, thereby causes resistance for chain 8 motions.Chain 8 and sprocket wheel 9 also can be replaced with belt or belt pulley, and its result is basic as above-mentioned identical.
The automatic adaptation wind direction mechanism of this blower fan is identical with general wind-power electricity generation blower fan, is not described in detail in this.
The utility model is owing to adopted sail shape blade, fully, maximally utilised wind energy, sail shape blade has movable and fixed two kinds, not only novel structure, simple, and use reliably, opened up new approach for utilizing wind energy more effectively, fully.
