Needed starting wind power is greatly reduced so that the wind blade is especially suitable for the small and medium-sized wind field generator set.
Description
Technical field
The utility model belongs to wind power equipment accessory technical field, relates in particular to a kind of vertical axis wind generator fan blade.
Background technique
The type of wind-power electricity generation fan blade comprises two kinds of horizontal axis fan blade and pivotal axis fan blades, and wherein the horizontal axis fan blade is used for large-scale wind power generating set, only is used in the zone of wind speed greater than 3 meter per seconds; Then use the wind power generating set of pivotal axis fan blade formation less than the zone of 3 meter per seconds at wind speed.The employed pivotal axis fan blade of wind power generating set is two " H " type structures at present; This wind power generating set is because the defective on the blade structure; It starts wind speed more than 2 meter per seconds; And the fan blade impeller of this structure is four leaves or five impeller structures, is difficult to guarantee the uniformity and the symmetry properties of blade installation, causes startup vibration, damage to cause short problem in working life easily.
The model utility content
The purpose of the utility model just provides a kind of simple in structure, low vertical axis wind generator fan blade of startup wind speed.
Realize that the technological scheme that the utility model above-mentioned purpose is adopted is:
A kind of vertical axis wind generator fan blade is characterized in that: comprise that the middle part is provided with the rotating shaft fixing frame of vertical rotating shaft, the end of wherein said vertical rotating shaft is provided with the fixed mechanism that can be connected with alternator shaft; The sidepiece of said rotating shaft fixing frame evenly be provided with its section be the arc rotating shaft to spiral some leaf blades, and make said rotating shaft fixing frame be included in the arc of said leaf blade.
The additional technical feature that constitutes above-mentioned vertical axis wind generator fan blade also comprises:
---described internal diameter blade is to being provided with some raised lines, and makes the face of going for a drive of leaf blade form some grades of lattice;
---described leaf blade is " C " type shape;
---described rotating shaft fixing frame is the shape frame structure in the shape of a spiral, and the air channel that makes formation connection between said leaf blade;
---the helicity of said rotating shaft fixing frame is 180 degree;
---the sidepiece of said rotating shaft fixing frame is symmetrically arranged with two leaf blades;
---described leaf blade is the glass fibre reinforced plastic integral structure.
A kind of vertical axis wind generator fan blade that the utility model provided; Since the structure of this fan blade by the middle part be provided with the rotating shaft fixing frame of vertical rotating shaft, the fixed mechanism that is connected with alternator shaft and in the shape of a spiral 180 spend shapes some leaf blades constitute; How the direction of therefore no matter the wind comes from changes can both guarantee that wind energy conversion system rotates; And can under the wind speed of 0.7 m/s, just can start, it starts wind-force and reduces greatly.
Description of drawings
The structural representation of the vertical axis wind generator fan blade that Fig. 1 provides for the utility model;
Fig. 2 is the structural representation of above-mentioned vertical axis wind generator fan blade end;
Fig. 3 is for constituting the structural representation of above-mentioned vertical axis wind generator fan blade rotating shaft fixing frame.
Embodiment
Explain further details below in conjunction with the concrete structure and the use principle of accompanying drawing to a kind of vertical axis wind generator fan blade that the utility model provided.
As shown in Figure 1, the structural representation of the vertical axis wind generator fan blade that provides for the utility model.The structure that constitutes this fan blade comprises the fixing frame 2 of the vertical rotating shaft 1 in the center that is provided with as shown in Figure 3; Be provided with the distortion spiral in the bilateral symmetry of this fixing frame and be first and second blades 3,6 that its section of " S " type is arc (being preferably " C " shape as shown in Figure 2), and make rotating shaft fixing frame 2 be included in the parenthetic of two blades 3,6; Be provided with the bindiny mechanism 5 like formations such as flange plate, coupling that can be fixedly connected with the rotating shaft of wind-driven generator in the end of above-mentioned vertical rotating shaft 1.Wherein above-mentioned first and second blades are light weight, corrosion-resistant and glass fibre reinforced plastic integral structure that intensity is high.
Its working principle is as shown in Figure 2; For constituting the structural representation of power-driven generator leaf; When wind direction blows (only being used for the explanation of this legend) from top to bottom; The area that goes for a drive of convex portion 8 of negative area 7 and second blade 6 that is connected with this negative area plane of first blade 3 that constitutes fan blade is greater than the choke area of the convex portion 9 of second blade 6, and the difference of the two is the wind-engaging that constitutes this fan blade and starts area, and realizes the rotation of driving generator; Owing to be fixed on the spiral that first and second blades 3,6 that the fixing frame bilateral symmetry is provided with fan blade are 180 degree; How the direction of therefore no matter the wind comes from changes can both guarantee that wind energy conversion system receives same wind-engaging and starts area, particularly very favourable for the startup of wind energy conversion system under the gentle breeze situation.
In the structure that constitutes above-mentioned leaf blade, to being provided with some raised lines 10 and making the face of going for a drive of leaf blade form some grades of lattice 11, the frictional force between distinguished and admirable body and the blade is increased at internal diameter blade, improved the utilization ratio of wind energy greatly.
In the structure of above-mentioned power-driven generator leaf; The rotating shaft fixing frame can also be the plate frame structure of helically twisted 180 degree as shown in Figure 3; Helically twisted with the fixing with it corresponding distortion of blade of this sheet frame fixing frame; The whole spiral vane that forms " S " type is a shape and structure then, and makes 3,6 of two leaf blades form the air channel 4 that is communicated with.This air channel makes the distinguished and admirable body A that is advanced by fan blade 3 concave surfaces institute pocket when promoting the blade rotation, gets into another blade 6 through this passage 4 and promotes this blades rotation, has improved distinguished and admirable body utilization ratio.Make this fan blade under the wind speed of 0.7 m/s, just can start, it starts wind-force and reduces greatly.
In the structure that constitutes above-mentioned vertical axis wind generator fan blade; Can be provided with as required axially to spirality, the section of " S " type is that the quantity that arc is preferably the leaf blade of " C " shape is three, four or more, and make leaf blade evenly be connected the sidepiece of fixing frame.
During use; Through bindiny mechanism the pivotal axis of this fan blade and wind-driven generator is linked together; Owing to be fixed on the spiral that the arc fan blade of rotating shaft fixing frame bilateral symmetry setting also is 180 degree respectively, promptly make to promote the rotation of arc fan blade and drive wind-driven generator to rotate from the wind of 360 degree directions.
