The described blade structure that is used for vertical axis aerogenerator, its further characteristics be, blade body is projected as a crotch from the top toward bottom direction on a plane.
The described blade structure that is used for vertical axis aerogenerator, its further characteristics are, the remaining part of blade body except that dark concave arc section is to be used for the lead scrobicula segmental arc of dark concave arc section of wind, the length of scrobicula segmental arc is greater than the length of dark concave arc section, the scrobicula segmental arc is connected with dark concave arc section, and the joint seamlessly transits.
The described blade structure that is used for vertical axis aerogenerator, its further characteristics are that along the direction from dark concave arc section to the scrobicula segmental arc, the thickness of blade body reduces gradually.
The described blade structure that is used for vertical axis aerogenerator, its further characteristics are that the upper end at the back side of blade body is equipped with upper and lower fixed support.
The described blade structure that is used for vertical axis aerogenerator, its further characteristics are also to comprise swash plate, the concave arc shape windward side of the upper end connection blade body of swash plate, the concave arc shape windward side is obliquely installed relatively, and the top of swash plate connects the dark concave arc section of blade body.
The described blade structure that is used for vertical axis aerogenerator, its further characteristics are that a plurality of described swash plates are connected with blade body.
The described blade structure that is used for vertical axis aerogenerator, its further characteristics are the concave arc shape windward side secure bond of the upper end-face edge of swash plate and blade body.
Vertical axis aerogenerator of the present utility model comprises a plurality of blades, is characterized in, each blade is the blade structure with aforementioned arbitrary characteristics.
The utility model has the advantages that:
One, owing to have dark concave arc section, the moment of acquisition is big, gentle breeze just can start, and makes full use of wind energy resources as much as possible;
Its two owing to have swash plate, be exactly on calm rainy day, the gravity of rainwater also can promote the blade rotation.Improve the wind turbine equipment utilization ratio greatly, reduce the idle of wind turbine equipment.
Description of drawings
Fig. 1 is the stereogram that is used for the blade structure of vertical axis aerogenerator of the present utility model.
Fig. 2 is the plan view of blade structure shown in Figure 1.
Embodiment
As depicted in figs. 1 and 2, the vane of vertical shaft wind-driven generator structure comprises blade body 1, fixed support 2, support arm 3 and swash plate 4 up and down.
Blade body 1 back side is provided with fixed support 2 up and down, and the upper end, the back side of blade body 1 is equipped with a little higher than support arm 3 of fixed support 2 up and down.Blade body 1 has concave arc shape windward side 100, concave arc shape windward side 100 has the dark concave arc section 101 away from the center of rotation axis of blade body 1, the curvature of dark concave arc section 101 is maximum in the curvature of whole concave arc shape windward side, becomes the concave arc depths of blade body.
Preferably, as shown in Figure 2, blade body 1 is projected as a crotch from the top toward bottom direction on a plane.
Preferably, as depicted in figs. 1 and 2, the remaining part of concave arc shape windward side 100 except that dark concave arc section 101 is to be used for the lead scrobicula segmental arc 102 of dark concave arc section 101 of wind, the length of scrobicula segmental arc 102 is greater than the length of dark concave arc section 101, scrobicula segmental arc 102 is connected with dark concave arc section 101, and the joint seamlessly transits.Scrobicula segmental arc 102 and dark concave arc section 101 in Fig. 1, Fig. 2 by the vertical plane of A by a dotted line separately.
Preferably, as shown in Figure 2, along the direction from dark concave arc section 101 to scrobicula segmental arc 102, the thickness of blade body reduces gradually.
