Abstract
The invention provides a vertical axis wind turbine, and belongs to the field of wind power generation. The vertical axis wind turbine solves problems that an existing resistance type vertical axis wind turbine is low in wind energy utilization rate, and a lift type vertical axis wind turbine is difficult to start. The vertical axis wind turbine comprises a vertical shaft, horizontal strutting pieces, and horizontal blades. The horizontal strutting pieces are installed on two sides of the vertical shaft, and the surface of the horizontal strutting piece is designed in certain streamline. The horizontal blades are installed on the horizontal strutting pieces, and form a resistance type blade combination. The horizontal blades comprise upper horizontal blades, lower horizontal blades, gears, and shafts. When no wind exists, the horizontal blades of the vertical axis wind turbine are in an opening state, and when certain wind acts on the horizontal blades, on a side of the vertical shaft, the horizontal blades are in the opening state, and wind collection area is relatively large, and on the other side of the vertical shaft, the horizontal blades which are in the opening state when no wind exists would fold under wind action, and the wind turbine is in a streamline integrally, so wind resistance is very low. Therefore, wind power difference on two sides of the vertical shaft makes the wind turbine rotate and start operation.
Description
Technical field
The invention belongs to wind power generation field.Be specifically related to a kind of vertical axis windmill.
Background technique
Wind energy conversion system majority common is at present horizontal-shaft wind turbine.And existing resistance-type vertical axis wind turbine wind energy utilization is lower, lift vertical shaft wind energy conversion system is difficult to self-starting.
Summary of the invention
The present invention is a kind of vertical axis windmill.Horizontal blade is open configuration when calm; When there being certain wind-force effect, in the side of vertical shaft, horizontal blade is still open configuration, and collection wind area is larger; At the opposite side of vertical shaft, be that the horizontal blade of open configuration will close up under wind-force effect time calm, overall in streamlined, therefore suffered windage is very little; Therefore the wind-force official post wind energy conversion system of vertical shaft both sides rotates and starts working.
A kind of vertical axis windmill provided by the invention, is characterized in that: it comprises vertical shaft, horizontal support member and horizontal blade.Horizontal support member is arranged on vertical shaft both sides.Horizontal blade is arranged in horizontal support member, forms the combination of resistance type blade.Horizontal blade comprises horizontal blade, lower horizontal blade, gear and axle.Upper horizontal blade can sway respectively with lower horizontal blade together with gear, to realize opening or closing up; The lower surface of the upper surface and lower horizontal blade of wherein going up horizontal blade is all designed to certain streamlined, and it is streamlined to reduce resistance for making upper and lower horizontal blade close up rear entirety.Horizontal support member surface is also designed to certain streamlined.
The resistance type vane group of wind energy conversion system of the present invention is combined in outer end, vertical shaft both sides mounting surface and has certain fairshaped lift-type blade, just can form a liter resistance combined type blade combination; Wherein in same vertical guide, the quantity of resistance type blade combination can be one or more than one, installs in turn on the vertical axis up and down.
Wind energy conversion system of the present invention, in different vertical guides, the quantity of the combination of resistance type blade or the combination of liter resistance combined type blade can be more than two pieces or two pieces, installs on the vertical axis in turn up and down, but uniform in horizontal projection.
Wind energy conversion system can be designed to resistance-type vertical axis wind turbine or rise resistance combined type vertical axis windmill by the working principle of wind energy conversion system of the present invention according to actual needs.
In the present invention, the material of all parts and size all require to determine according to the output of actual product and product technology.
Accompanying drawing explanation
Fig. 1 is this wind energy conversion system principle schematic;
In figure, vertical shaft 1, horizontal support member 2, horizontal blade 3.
Fig. 2 is the view of horizontal blade when opening and close up;
In figure, upper horizontal blade 301, lower horizontal blade 302, gear 303, axle 304.
Embodiment
As shown in Figure 1, vertical axis windmill of the present invention comprises vertical shaft 1, horizontal support member 2 and horizontal blade 3.
Horizontal support member 2 is arranged on vertical shaft 1 both sides.Horizontal blade 3 is arranged in horizontal support member 2, and horizontal blade 3 comprises horizontal blade 301, lower horizontal blade 302, gear 303 and axle 304.Upper horizontal blade 301, lower horizontal blade 302 can rotate around axle 304 respectively together with gear 303, to realize opening or closing up; The lower surface of the upper surface and lower horizontal blade 302 of wherein going up horizontal blade 301 is all designed to certain streamlined, and it is streamlined to reduce resistance for making horizontal blade 301 and lower horizontal blade 302 close up rear entirety.Horizontal support member 2 surface is also designed to certain streamlined.The shaft resistance type windmill being now combined into one group for resistance type vane group illustrates working principle of the present invention:
First in calm situation, in vertical shaft 1 both sides, lower horizontal blade 302 rotates around axle 304 under gravity, and drives upper horizontal blade 301 upwards to rotate by gear 303, so upper horizontal blade 301 and the open-shaped state of lower horizontal blade 302, as shown in A-A in Fig. 2.When there being certain wind-force effect, in the side of vertical shaft 1, horizontal blade 3 is still open configuration, and collection wind area is larger; At the opposite side of vertical shaft 1, be that the horizontal blade 3 of open configuration will close up under wind-force effect time calm, overall in streamlined, as shown in B-B in Fig. 2, therefore suffered windage is very little; Therefore start to rotate at the wind-force official post wind energy conversion system of vertical shaft 1 both sides, shaft resistance type windmill is started working.
The resistance type vane group of wind energy conversion system of the present invention is combined in outer end, vertical shaft 1 both sides mounting surface and has certain fairshaped lift-type blade, just can form a liter resistance combined type blade combination; Wherein in same vertical guide, the quantity of resistance type blade combination can be one or more than one, installs in turn on the vertical axis up and down.
Wind energy conversion system of the present invention, in different vertical guides, the quantity of the combination of resistance type blade or the combination of liter resistance combined type blade can be more than two pieces or two pieces, is arranged in turn on vertical shaft 1 up and down, but uniform in horizontal projection.
Wind energy conversion system can be designed to resistance-type vertical axis wind turbine or rise resistance combined type vertical axis windmill by the working principle of wind energy conversion system of the present invention according to actual needs.
In the present invention, the material of all parts and size all require to determine according to the output of actual product and product technology.
