Abstract
The utility model relates to a wind blade for a horizontal aerogenerator, which comprises a wind blade support and blades, wherein the blade support consists of a left vertical shaft and a right vertical shaft as well as an upper horizontal shaft and a lower horizontal shaft which are pairwise perpendicular and intersected; the blades are movably connected with the upper horizontal shaft; and the lower sides of the blades are positioned below the lower horizontal shaft of the wind blade support when the blades droop naturally. The wind blade for a horizontal aero-generator can be free from the influence of wind direction and can not be blown down by wind no mater what the size of the wind power is. When the wind comes, the blades of the wind blade at one side along the direction of the wind block the horizontal shafts on the wind blade support under the action of the wind, while the blades of the wind blade at the other side against the direction of the wind are blown off by the wind, so that the wind can smoothly pass through without resistance. At this time, the wind blade can rotate to drive a generator to work.
Description
Technical field
The utility model relates to a kind of horizontal wind power generator, relates in particular to a kind of fan blade of horizontal wind power generator.
Background technique
Traditional energy comprises oil, coal, nuclear energy etc., belongs to non-renewable resources, now just by a large amount of consuming, and has caused very big environmental pollution.This problem has caused people's attention and attention, and people have found reproducible clean energy resource to replace at present, as solar energy, wind energy etc.Wind-driven generator utilizes wind energy exactly, is the device of electric energy with wind energy transformation, at present in some areas in extensive use.Present wind-driven generator generally all is a vertical wind driven generator, its fan blade will face the direction of wind, thereby utilize wind-force to drive fan blade and rotate the generating of drive separated motor, its generated energy and wind-force size have direct relation, if but wind-force is excessive, the phenomenon that is easy to cause fan blade to be turned over by big wind owing to its stressed reason takes place.And the direction of fan blade will must make improvements the fan blade of wind-driven generator to the problem of influence in order to solve the wind-driven generator wind-engaging at any time along with the direction variation of wind is made adjustment.
Summary of the invention
The object of the present invention is to provide a kind of not wind-engaging to the fan blade that influences the horizontal wind power generator that freely rotates.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of fan blade of horizontal wind power generator, fan blade comprises vane frame and blade, vane frame by left and right vertical pivot and up and down transverse axis square crossing in twos form, blade and last transverse axis flexibly connect, the lower side of blade is positioned at the below of the following transverse axis of vane frame when leaf natural is sagging.The fan blade of this wind-driven generator is when wind is come, the leaf blade of direction with the wind on one side is at the transverse axis of wind action lower blade retaining on the fan blade frame, another side then is to be opened by wind against the leaf blade of the direction of wind, wind energy is not enough smoothly by causing resistance, at this time fan blade just can rotate, thereby drives generator work.
Described vane frame inside also is provided with some transverse axis, and each transverse axis all is connected with blade and blade can rotate around transverse axis, and when leaf natural was sagging, the bottom position of blade slightly grew the transverse axis that is positioned at its below.The multiple-blade fan blade can better utilization wind-force improves the efficient of wind-power electricity generation.
The fan blade of the utility model horizontal wind power generator, not wind-engaging to the influence and the size of wind-force the phenomenon of being fallen by wind can not take place.When wind is come, the leaf blade of direction with the wind on one side is at the transverse axis of wind action lower blade retaining on the fan blade frame, another side then is to be opened by wind against the leaf blade of the direction of wind, wind energy is not enough smoothly by causing resistance, at this time fan blade just can rotate, thereby drives generator work.

Embodiment
Embodiment 1: present embodiment provides a kind of fan blade of horizontal wind power generator, this fan blade comprises vane frame and blade 1, vane frame is made up of left vertical pivot 2, right vertical pivot 3 and last transverse axis 4 and following transverse axis 5 square crossing in twos, blade 1 and last transverse axis 4 flexibly connect, and the lower side of blade 1 is positioned at the below of the following transverse axis 5 of vane frame when blade 1 is sagging naturally.When wind is come, the leaf blade of direction with the wind on one side is at the transverse axis of wind action lower blade retaining on the fan blade frame, another side then is to be opened by wind against the leaf blade of the direction of wind, wind energy is not enough smoothly by causing resistance, at this time fan blade just can rotate, thereby drives generator work.
Embodiment 2: the fan blade of present embodiment horizontal type generator adopts mutliblade mode, also be provided with 2 transverse axis 6 in the inside of vane frame, being provided with each transverse axis 6 all is connected with blade 1 and blade 1 and can rotates around transverse axis 6, when blade 1 was sagging naturally, the bottom position of blade 1 slightly grew the transverse axis that is positioned at its below.Other structure is identical with embodiment.
Claims (2)
1, a kind of fan blade of horizontal wind power generator, it is characterized in that fan blade comprises vane frame and blade, vane frame by left and right vertical pivot and up and down transverse axis square crossing in twos form, blade and last transverse axis flexibly connect, the lower side of blade is positioned at the below of the following transverse axis of vane frame when leaf natural is sagging.
2, a kind of horizontal wind power generator according to claim 1, it is characterized in that described vane frame inside also is provided with some transverse axis, each transverse axis all is connected with blade and blade can rotate around transverse axis, and when leaf natural was sagging, the bottom position of blade slightly grew the transverse axis that is positioned at its below.
