Description
Technical field
The utility model relates to technical field of wind power generating equipment, particularly relates to a kind of vertical axis wind power generation blade.
Background technique
Wind-power electricity generation utilizes natural wind resource to generate electricity, and is that a kinetic energy of keeping watch becomes mechanical kinetic energy, then is the process of electric power kinetic energy changes mechanical energy.Wind-driven generator utilizes wind-force to drive blade rotary, impels electrical power generators.Current wind generating technology is approximately the gentle breeze speed of three meters per second, just can start generating.
Current small-sized wind power generator many employings horizontal axis, the blade structure of the similar windmill of its blade installation structure, the wind-driven generator of horizontal axis needs tail vane or driftage setting to carry out doing character and conduct, driftage turns to and needs certain hour, under wind vector frequently situation, generator needs continuous adjustment direction, reduces generating efficiency undoubtedly; And the startup wind-force of the wind-driven generator of horizontal axis is comparatively large, needs higher wind speed to meet power generation needs.
Model utility content
Goal of the invention of the present utility model is to provide a kind of vertical axis wind power generation blade, and the technological scheme adopting the utility model to provide while gentle breeze level wind-force starts generating, can also improve the utilization ratio of blade to wind energy, improve wind power generation efficiency.
In order to reach foregoing invention object, the utility model provides a kind of vertical axis wind power generation blade, comprises the vertical blade be fixedly installed on by support in the vertical rotating shaft of generator; Described blade annular array is evenly arranged at around described rotating shaft; Described blade comprises radial all towards arc external side and the inner side surface of described rotating shaft; The center of circle of the outer side surface of described blade is all positioned at described rotating shaft place, and radius is isometric; Described outer side surface is fixedly connected with one end of inner side surface; The other end of described outer side surface and inner side surface is provided with arc junction surface; Described outer side surface, inner side surface and junction surface Formation cross-section shape are the blade hooking beautiful shape.
Because the utility model adopts pivotal axis blade to generate electricity, blade can be rotated under the wind energy effect of all directions, improve generating efficiency, and blade is sectional shape be hook beautiful shape, when being positioned at the junction surface Forced rotation of the blade of rotating shaft side, resistance then drops to minimum by the blade being positioned at rotating shaft opposite side, meanwhile, the center of circle of the outer side surface of blade is all in rotating shaft place, and radius is isometric, making outer side surface form a circle, reduce further the resistance that blade is subject to when rotating.
As further improvement of the utility model, described support comprises the first support arm and the second support arm; Described first support arm is connected with the end of the second support arm, and is connected with described rotating shaft; Described first support arm is connected with described blade respectively with the other end of the second support arm, and arranges with described blade triangularity.The support of this structure improves the steadiness of blade, reduces rate of fault of the present utility model.
As further improvement of the utility model, the quantity of described blade is at least 2.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below.Apparently, the accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the utility model embodiment plan view;
Fig. 2 is the utility model embodiment plan view;
Fig. 3 is the utility model embodiment blade view.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described.Obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment 1
As shown in Figure 1, present embodiment discloses a kind of vertical axis wind power generation blade, comprise the blade 10 vertically arranged, as shown in Figure 2, blade 10 is fixedly installed in the vertical rotating shaft 30 of generator by support 20, and annular array is evenly arranged at around rotating shaft 30.As shown in Figure 3, blade 10 comprises outer side surface 11 and the inner side surface 12 of cambered surface.The center of circle of the outer side surface 11 of its Leaf 10 is all positioned at rotating shaft 30 place, and radius is isometric, makes the outer side surface 11 of each blade, and namely the outer side surface of blade 10 forms a circle; The radial direction of inner side surface 12 is towards rotating shaft 30.Outer side surface 11 is fixedly connected with one end of inner side surface 12, forms a knuckle 13; The other end is provided with arc junction surface 14, forms wind-receiving face.The joint of this arc junction surface 14 and outer side surface 11 and inner side surface 12, for seamlessly transitting, can reduce resistance.Outer side surface 11, inner side surface 12 and junction surface 14 Formation cross-section shape are the blade 10 hooking beautiful shape.
Because blade 10 is vertically arrange, blade 10 can be rotated under the wind energy effect of all directions, and blade 10 is for sectional shape is for hooking beautiful shape, be positioned at the junction surface 14 of the blade 10 of rotating shaft 30 side when wind-force effect lower stress rotates, be positioned at the existence of blade 10 due to knuckle 13 of rotating shaft 30 opposite side, then the resistance of wind-force is dropped to minimum, reach the effect effectively utilizing wind energy, simultaneously, the center of circle of the outer side surface 11 of blade 10 is all at rotating shaft 30 place, and radius is isometric, outer side surface 11 is made to form a circle, reduce further the resistance that blade 10 is subject to when rotating.
As shown in Figure 1, in order to improve the steadiness of blade 10, support 20 comprises the first support arm 21 and the second support arm 22, first support arm 21 is connected with the end of the second support arm 22, and be connected with rotating shaft 30, first support arm 21 is connected with blade 10 respectively with the other end of the second support arm 22, and arranges with blade 10 triangularity.
Present embodiment discloses a kind of power generation blade of 6 blades, certain blade 10 quantity is more than 2 or 2 can reach the effect improving wind energy utilization too.
