Description
Technical field:
The utility model belongs to a kind of wind power plant, particularly a kind of wind sail type double-vane wind generating unit.
Background technique:
The shortcoming of existing power-driven generator leaf blade is that narrow elongated, fan blade substantially all is fixed, certain angle is arranged, wind is to blow on the blade of fan blade earlier and on the angle of the blade of fan blade, fan blade is rotated, so no matter be fan blade, still fan blade upper angle all can loss and weaken certain wind energy, the narrow design of fan blade, be the biggest factor that causes the wind-resources waste, so cause utilization ratio of wind energy to reduce.
The blade that also has the numerous species type, the design of phase big blade blade and mutliblade design.The design of this blade is also big because of the big resistance of blade, and the many resistances of fan blade are also many.Install the comparison difficulty, poor safety performance.Discomfort should have the strong wind area to install and use,
Also have many convex-concave blades, type watt type blade, the screw type blade, the design of these several blades has a lot of defectives, and reason is that every ring circles, and all can run into once the impact of reverse wind-force, because blade all is fixed, also has a greatly reduced quality to wind-resources.
Show according to the investigation interrelated data, the leaf blade design of existing wind-driven generator, utilization ratio of wind energy can only be used about 6 percent five of wind rate, and also not high effect is also bad to also have multiple design wind energy utilization.
The model utility content:
The purpose of this utility model is to have solved original blades of wind generating set blade problems such as unreasonable wind energy utilization is low, a kind of wind sail type double-vane wind generating unit that provides are provided.
To achieve these goals, the utility model has adopted following technological scheme:
A kind of wind sail type double-vane wind generating unit, comprise supporting frame, be connected with generator on the supporting frame, it is characterized in that generator is connected with the central shaft that matches, the two ends of central shaft are connected with polygonal wind wheel framework respectively, and each wind wheel frame edge edges and corners is respectively equipped with rotating shaft, and each rotating shaft is a hinged blade respectively, when blade is turned to different angles, forms to support with adjacent inner gimbal or adjacent external frame respectively and cooperate.
On the basis of technique scheme, following further technological scheme can be arranged:
On the central rotating shaft or motor be provided with the facing the wind fan blade control strip of direction of control.
Advantage of the present utility model:
The utilization ratio of wind energy of the wind sail type double-vane wind generating unit that the utility model provides reaches more than 60 percent.It is made up of multi-part, and dismounting is flexible, and is quick for installation, and convenient transportation adapts to large-scale and the small power generation unit, and miniature and breeze type generator set, has solved original blades of wind generating set blade and has designed problems such as unreasonable wind energy utilization is low.
Description of drawings:
Fig. 1 is the plan view of the utility model reality.
Embodiment:
As shown in Figure 1, a kind of wind sail type double-vane wind generating unit that the utility model provides comprises supporting frame 9, be connected with on the supporting frame 9 can sense of rotation generator 3, be connected with the central shaft 2 that matches on the generator 3, central shaft 2 can drive generator for electricity generation when rotating.Be connected with hexagonal wind wheel framework respectively at the two ends of central shaft 2, it is made up of flange shaft 5, inner gimbal 6 and external frame 7, be respectively equipped with rotating shaft 8 in each wind wheel frame edge edges and corners, each rotating shaft 8 is the hinged rotary blades 1 of difference, when blade 1 is turned to different angles, forms to support with adjacent inner gimbal 6 or adjacent external frame 7 respectively and cooperate.In addition, central rotating shaft 2 is provided with fan blade control strip 4.
Working procedure of the present utility model:
As shown in Figure 1, illustrate with wherein first blade, all be that the front is subjected to air blade with the leaf blade more than the central shaft, with the wind the time, the front that can obtain wind-force promotes, in the reverse side of blade 1 is close to when wind-engaging on the stress frame 6, refer to that blade A face also is positive stressed, the vacuum side of blade that is close on the stressed inner gimbal also is the B face, and first blade is counted from zero degree, the leaf blade that rotates around central shaft under the promotion of wind-force, entered angular range, fan blade angle is the time marquis of 1 degree to 120 degree, and the front that can both obtain wind-force promotes, and particularly fan blade angle is in 90 when spending, when the fan blade amount of collecting folk songs at this time is maximum, because leaf blade front at this time is in face of wind direction, the angle of leaf blade and wind direction keeping parallelism, the period that the big utilization ratio of wind-force is high.Fan blade be in 90 to 120 the degree angle the time be the gentle breeze zone.When fan blade is in the angle of 120 to 180 degree, be calm zone, the calm zone of why saying so? because the wind-force that the central shaft plane is above, all stopped and utilized at the fan blade of 1 to 120 degree by angle, be calm zone thus.But be in this regional leaf blade and also do not have free, be the time period that fan blade rotates flexibly this time, and fan blade is along with the rotation of wind wheel, and fan blade has forwarded on the B stress frame from the A stress frame, and the vane stress face of fan blade also changes.
When entering between 180 to 300 degree from the blade of fan blade, at this moment leaf blade has been in wind wheel central shaft position once, so the wind-force that once passes through from central shaft can blow to, on the leaf blade B face of 180 to 300 degree centered by central shaft, it also is the reverse side of leaf blade, at wind wheel, fan blade, angle, effect under begin the stressed generating wheel of giving again, reason is, because the blade of fan blade is stopped by stressed external frame, the blade of fan blade and inner gimbal present the angles of 60 degree, and the blade that this angle fan blade arranged just can secondary loading, can be described as blade adds angle and is adding that wind speed rotates strength exactly, situation comes to this, and that is to say wind sail type double-vane wind-power electricity generation wheel, the blade of fan blade when whenever circling, the capital is subjected to the promotion of twice wind-force, thus with central shaft, centered by calculate, 1 to 120 degree is the zone of collecting folk songs, the front of leaf blade, 180 to 300 is that the power zone is also given at the leaf blade back side when spending, and also is the wind-engaging zone.
When fan blade forwards 300 to 360 to when spending, fan blade is got back to the flexible area of fan blade again, and blade is not stressed, and the blade of fan blade freely swings with the wind, prepares the running that enters the following cycle.
Wind sail type double-vane wind-power electricity generation wheel has a plurality of blade link central shafts, and each blade can rotate 60 degree flexibly, around central shaft 360 degree.Vane group is contained between central shaft and the framework, and when with the wind, the blade of fan blade reclines on the stress frame, and blade angle from 1 to 120 degree in the time of around the central shaft rotation, can both obtain the thrust of wind.It is stressed that blade in the time of with the wind more than 60% can both obtain fine work, and by stress frame, unification flows to central shaft, behind each vane stress, all can drive central shaft behind all vane stress, central shaft rotated drive generator set.
