Abstract
A rolling blade generates energy through rolling, whereon the energy generation section of the blade vertically set wind catch bands. With the additional vertical bands, move wind or water will be caught when the blades rotate and simultaneously reduce the loss of moving wind or water, therefore increase the energy conversion rate.
Description
Technical field
The present invention relates to a kind of rotation blade, mainly refer to obtain the employed blade of equipment of transformation of energy, comprise all kinds of propeller blades (as the propeller blade of aircraft, ships), all kinds of impeller of blower (as the fan blade of electric fan, ventilating fan), windmill fan blade etc. by the rotation of blade.
Background technique
At present all equipment by blade rotation acquisition transformation of energy, the transformation of energy face of its blade is all formed by a smooth surface, careful people can observe and use a period of time when electric fan and do not clean in life, air quantity can reduce, this is because dust in air is filled and led up the recess of blade, makes blade become Paint Gloss, and the amount of going for a drive of blade reduces, the ability of air flows is reduced, and meaning is promptly transferred to the conversion ratio reduction of wind energy by electric energy.In fact at present producer does smoothly to make it more attractive in appearance as far as possible, but makes the blade amount of going for a drive too little like this, thereby present electric fan energy conversion rate is lower.Also there is same problem for some other propeller blades, windmill fan blade etc. that obtain the equipment of transformation of energy such as aircraft, ships by blade rotation.
Summary of the invention
The object of the present invention is to provide a kind of rotation blade that can improve the energy conversion rate energy saving.
The technological scheme that the present invention takes is the sheet that goes for a drive that projection is set at the transformation of energy face of existing blade.
The described sheet that goes for a drive is provided with the bar that goes for a drive of dimpling.
Because the present invention has increased the sheet that goes for a drive at existing blade transformation of energy face, the blade amount of going for a drive strengthens, these sheets that go for a drive can actively be participated in the stirring of air when motor rotates, and make the least possible loss of the air that has flowed, and all push the place ahead to, energy conversion rate is improved significantly, thereby has saved the energy.This inventor has been carried out following experiment:
Experiment one: the existing blade of electric fan is taken off, install blade of the present invention, found that the air quantity of electric fan obviously strengthens.Use the electric fan of blade coupling 45W motor of the present invention, its air quantity is not less than the air quantity of traditional 60W electric fan.
Experiment two: the windmill of the homemade existing fan blade of Jiang Yitai and an electric fan are placed on the good position of mark, with electric fan facing the wind car brush, the rotating speed of windmill is that per minute 80 changes, existing fan blade with windmill takes off then, load onto fan blade of the present invention, the former mark position that is put back into windmill continues with former electric fan it to be blown, and it is that per minute 110 changes that the result records rotating speed, two compare, and latter's (having used blade of the present invention) changes than the former Revolution Per Minute fast 30.
Experimental results show that blade of the present invention compares with traditional blades, the energy conversion rate of electric fan, windmill is obviously increased, because properller has the identical of essence with electric fan, can infer thus when using blade of the present invention on the propeller cavitation can obviously increase its fltting speed equally, boats and ships too just medium be water.So the present invention can make electric fan, comprises that the propeller cavitation energy conversion rate of ventilating fan, windmill and aircraft boats and ships obviously increases, and can reach the effect of energy saving thus.

Embodiment
What Fig. 1-Fig. 3 reflected is that the present invention is to the improved example of conventional arched blade.Among the figure as can be seen, protruding three (being not limited to three) are all arranged on the transformation of energy face 1 of every blade, and sheet 2 goes for a drive, on the sheet 2 that goes for a drive, also be provided with the bar 3 that goes for a drive of some dimplings, the shape of sheet 2 of going for a drive and the shape kissing of fan blade, the slight curving (see figure 2) of its shape of cross section, it is identical that bending direction and electric fan turn to, and the shape of the bar 3 that goes for a drive is seen Fig. 2 and Fig. 3.These go for a drive sheet and the bars that go for a drive can actively be participated in the stirring of air when motor rotates, and make the least possible loss of the air that has flowed, and all push the place ahead to, and it is more much bigger than using traditional fan blade to make air quantity thus, and this result also fully is confirmed in inventor's experiment.This arc shaped blade of the present invention not only is used for electric fan, the propeller cavitation that also can be used for ships, just the two medium is not an air with the former, the latter is a water, therefore can infer after the propeller of ships is used blade of the present invention, under the constant situation of horsepower, the driving velocity of propeller cavitation can obviously be accelerated.
Fig. 4 has reflected the structure of second mode of execution of the present invention, this is a kind of straight line type blade, we can see in the drawings, the sheet that goes for a drive that it is provided with above is straight, and is identical with blade shape, from the transverse section (identical with Fig. 2), also be towards a direction, slightly bending is arranged so that go for a drive, the bar 3 that goes for a drive (identical with Fig. 2 and Fig. 3) of some dimplings also can be set on the sheet 2 that goes for a drive, this blade can be used for ceiling fan, helicopter, windmill (wind-power electricity generation).In the time of on being used in ceiling fan or aircraft, the bending direction of the sheet that goes for a drive accelerates the air quantity increase of ceiling fan, the fltting speed of properller when identical with the rotation postive direction of ceiling fan or properller; And the bending direction of the sheet that goes for a drive when being used on the windmill should facing the wind direction, and it can make windmill obtain higher rotating speed under the identical situation of natural wind, and sends more.
Fig. 5 and Fig. 6 have reflected the structure of the 3rd mode of execution of the present invention, this is a kind of blade of pointed shape, its sheet that goes for a drive of being provided with above is to be folded in half into a wedge angle and to be formed by sheet always as can be seen in the drawings, its objective is and reduce the front resistance of air when rotating and increase the back amount of going for a drive that this blade is mainly used in the blade of wind-driven generator for blade.
No matter existing in a word blade why shape, as long as increase the sheet that goes for a drive of projection on its transformation of energy face, the energy conversion rate of this blade is significantly improved, and reaches purpose of energy saving.
