Abstract

The utility model provides a guide-flow type vertical axis wind turbine, which relates to an electric power generating equipment converting the wind power into mechanical energy. The utility model is characterized in that a fixed guide flow cover is arranged at a periphery of a fan blade of wind turbine, and the guide flow cover comprises a plurality of guide flow plates which are arranged to form a circular ring according to the same direction. The wind from any direction passing through the guide flow cover can form the direction-fixed rotational wind at the middle of the guide flow cover under the action of the guide flow plates to actuate the rotation of the fan blade so as to eliminate the resistance of the fan blade back of the wind turbine. As the cross section of the outer vent-hoe of the guide flow cover is larger than the cross section of the inner vent-hole of the guide flow cover, the wind speed toward the fan blade of the wind turbine is higher than the wind speed at the periphery of the guide flow cover. To sum up, the utility model can availably improve the utilization efficiency of the wind energy of the vertical axis wind turbine.

Description

The flow guide type full blast is to vertical axis windmill
Technical field
A kind of flow guide type full blast relates to wind-force is changed into mechanical energy and can be used for power generating equipment to vertical axis windmill.
Background technique
Wind energy conversion system can be divided into two classes substantially: horizontal-shaft wind turbine and vertical axis windmill.Comparatively speaking, horizontal-shaft wind turbine is because have wind apparatus, and the surface of revolution that can make wind wheel is over against wind direction, thereby obtains higher wind energy utilization; The wind wheel of vertical axis windmill makes the axle rotation towards the thrust that a side of wind can be subjected to wind, and the wind-force that is subjected to of a side of wind can produce resistance to rotation dorsad, thereby its wind energy utilization is lower.Though through improvement, but still not as horizontal-shaft wind turbine.Though not as horizontal-shaft wind turbine, its structure is simple more than horizontal-shaft wind turbine to utilization ratio of wind energy for vertical axis windmill.
The model utility content
No matter how the purpose of this utility model provides a kind of wind direction, but the vertical axis windmill of equal high-efficient operation.
This flow guide type full blast is in the periphery of wind energy conversion system fan blade one fixing air guide sleeve to be installed to vertical axis windmill, and air guide sleeve is an annulus that is arranged in by equidirectional by some guide plates.
No matter the wind from that direction blows when its process air guide sleeve, under the effect of guide plate, forms the revolution wind of fixed-direction at the middle part of air guide sleeve, the fan blade that promotes wind energy conversion system rotates.So just fundamentally eliminated the resistance that acts on the wind energy conversion system fan blade back side.Because the collar extension ventilation section of air guide sleeve is greater than its internal orifice ventilation section, thereby make the wind speed that blows to the wind energy conversion system fan blade the speed of the wind comes from greater than the air guide sleeve periphery.Can effectively improve the Wind Power Utilization efficient of vertical axis windmill in a word.

Fig. 1 is the schematic top plan view of this flow guide type full blast to vertical axis windmill.
Embodiment
Embodiment's (seeing figure):
This flow guide type full blast is in the periphery of wind energy conversion system fan blade 1 a fixing air guide sleeve to be installed to vertical axis windmill, and air guide sleeve is an annulus that is arranged in by equidirectional by some guide plates 2.Guide plate can be curved face type also can be plane.Guide plate promptly can be a thin plate, also can replace with wall.
