Abstract
The utility model relates to the technical field of a wind wheel, in particular to a diversion-type wind wheel, which is characterized in that a vertical central axis is arranged in the center of upper and lower cover discs; a plurality of vertical blades are arranged between the upper and lower cover discs; each blade is of an arc concave surface; the upper end of each blade is connected with the upper cover disc and the lower end is connected with the lower cover disc; the inner side of each blade parallel keeps a certain distance from the central axis; a diversion cavity chamber is formed in the center of the wind wheel by the upper and lower cover discs as well as a plurality of blades. Compared with the prior art, the wind wheel has good structural rigidity, long service life, reliable operation and convenient manufacture. The wind wheel plays a role of guiding wind flow and causes the concave surface on each blade to be simultaneously effected by the wind power; therefore, the wind power of the wind wheel can be increased by times so that utilization rate and output torque of wind energy can be increased and the balance degree of the torque along the circumference of the wind wheel is improved.
Description
[technical field]
The utility model relates to the wind wheel technical field, specifically a kind of guide flowing type wind wheel.
[background technique]
Containing huge energy in the natural wind, it is a kind of pollution-free, reproducible green energy resource.Utilize the wind energy service human, at first must convert wind energy to mechanical energy by wind wheel.Wind wheel can be divided into horizontal axis rotor and vertical axis rotor two big classes according to the structure difference.The blade of vertical axis rotor is a curve form, and under the wind-force effect, concave surface one side is rendered as pneumatic power, and convex surface one side is rendered as wind resistance, drives the difference generation of the original moment of wind wheel rotation by this dynamic resistance.Clearly, improve the approach of Wind Power Utilization usefulness, be to improve the poor of the dynamic resistance that is presented on the vertical axis rotor, promptly increase pneumatic power or reduce wind resistance.By adopting the water conservancy diversion principle that wind wheel structure is carried out innovative design, can realize above-mentioned target preferably.
[summary of the invention]
The purpose of this utility model is to provide a kind of modern design, well-set novel vertical-axis wind wheel, i.e. guide flowing type wind wheel.
For achieving the above object, design a kind of guide flowing type wind wheel, comprise upper cover plate (1), central shaft (2), blade (3), lower cover (4), it is characterized in that: the center of shrouding disc is provided with vertical center axis up and down; Some vertical vanes are housed, all curved curved surface of each blade up and down between the shrouding disc; The upper end of each blade is connected with upper cover plate, the lower end is connected with lower cover; The inboard of each blade all with the central axes certain distance that staggers, shrouding disc and some blades have constituted a water conservancy diversion chamber at the wind wheel center up and down, the quantity of described blade comprises more than 2 at least.
The utility model compared with prior art, structural rigidity is good, long service life, reliable, easily manufactured.By the effect of water conservancy diversion chamber, improved utilization ratio of wind energy and output torque effectively, improved equalising torque degree along the wind wheel circumference.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a water conservancy diversion chamber schematic representation of the present utility model;
Fig. 3 is a water conservancy diversion schematic diagram of the present utility model;
Appointment Fig. 1 is a Figure of abstract
Referring to accompanying drawing, 1 upper cover plate, 2 central shafts, 3 blades, 4 lower covers among Fig. 1
5 water conservancy diversion chambers among Fig. 2
[embodiment]
In conjunction with the accompanying drawings the utility model is described further, the manufacturing technology of this device is very clearly concerning this professional people.
The guide flowing type wind wheel comprises upper cover plate (1), central shaft (2), blade (3), lower cover (4) as shown in Figure 1, and it is characterized in that: the center of shrouding disc is provided with vertical center axis up and down; Some vertical vanes are housed, all curved curved surface of each blade up and down between the shrouding disc; The upper end of each blade is connected with upper cover plate, the lower end is connected with lower cover; The inboard of each blade all with the central axes certain distance that staggers, shrouding disc and some blades have constituted a water conservancy diversion chamber at the wind wheel center up and down.
Water conservancy diversion chamber (5) has shown that the guide flowing type wind wheel increases the principle of pneumatic power as shown in Figure 2, and upper and lower cover plate and some blades have just surrounded a water conservancy diversion chamber at the wind wheel center, can be to distinguished and admirable constraint guiding function.Its water conservancy diversion principle is: be blown into concave surface distinguished and admirable of arbitrary blade, after the work done of this blade, its wake flow is imported into chamber, and automatically derives and work done from the concave surface of rest blade.
Because the wind wheel of this structure can make the concave surface of every blade be subjected to the wind-force effect simultaneously, so the pneumatic power of wind wheel is multiplied, has improved utilization ratio of wind energy and output torque, and has improved the equalising torque degree along the wind wheel circumference.
Claims (2)
1, a kind of guide flowing type wind wheel comprises upper cover plate (1), central shaft (2), blade (3), lower cover (4), and it is characterized in that: the center of shrouding disc is provided with vertical center axis up and down; Some vertical vanes are housed, all curved curved surface of each blade up and down between the shrouding disc; The upper end of each blade is connected with upper cover plate, the lower end is connected with lower cover; The inboard of each blade all with the central axes certain distance that staggers, shrouding disc and some blades have constituted a water conservancy diversion chamber at the wind wheel center up and down.
2, a kind of guide flowing type wind wheel according to claim 1 is characterized in that the quantity of described blade comprises more than 2 at least.
