Description
Technical field:
The invention belongs to a kind of wind power plant, particularly a kind of cage wind generating unit.
Background technique:
The shortcoming of existing power-driven generator leaf blade is that narrow elongated, fan blade is substantially all fixed, certain angle is arranged, wind is first to blow on the blade of fan blade, and on the angle of the blade of fan blade, fan blade is rotated, so no matter be fan blade, or the fan blade upper angle all can loss and weaken certain wind energy, the narrow design of fan blade, the biggest factor that causes the wind-resources waste, so cause the 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 large because of the large resistance of blade, and the many resistances of fan blade are also many.Install more difficult, 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 is all 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, the utilization ratio of wind energy can only be used 6 percent five left and right of wind rate, and also not high effect is also bad to also have multiple design wind energy utilization.
Summary of the invention:
The objective of the invention is to have solved the problems such as the unreasonable wind energy utilization of original blades of wind generating set blade design is low, a kind of cage wind generating unit that provides.
To achieve these goals, the present invention has adopted following technological scheme:
A kind of cage wind generating unit, comprise supporting frame, be connected with generator on 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 respectively polygonal wind wheel framework, and each wind wheel frame edge edges and corners are 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 coordinate.
On the basis of technique scheme, following further technological scheme can be arranged:
On central rotating shaft or motor be provided with and control the fan blade control strip of direction windward.
Advantage of the present invention:
The utilization ratio of the wind energy of cage wind generating unit provided by the invention reaches more than 60 percent.It is comprised 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 the problems such as the unreasonable wind energy utilization of original blades of wind generating set blade design is low.
Description of drawings:
Fig. 1 is the plan view of reality of the present invention.
Embodiment:
As shown in Figure 1, a kind of cage wind generating unit provided by the invention comprises supporting frame 9, be connected with on supporting frame 9 can sense of rotation generator 3, be connected with the central shaft 2 that matches on generator 3, central shaft 2 can drive the generator generating when rotating.Be connected with respectively hexagonal wind wheel framework at the two ends of central shaft 2, it is comprised 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 coordinate.In addition, central rotating shaft 2 is provided with fan blade control strip 4.
Working procedure of the present invention:
as shown in Figure 1, illustrate with wherein first blade, all that the front is subjected to air blade with the leaf blade more than central shaft, with the wind the time, the front that can obtain wind-force promotes, the reverse side of blade 1 is close on interior stress frame 6 when wind-engaging, refer to that blade A face is also positive stressed, the vacuum side of blade that is close on stressed inner gimbal also is the B face, 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, the front that can obtain wind-force promotes, 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 large utilization ratio of wind-force is high.Fan blade is gentle breeze zones when being in the angle of 90 to 120 degree.When fan blade is in the angle of 120 to 180 degree, be calm zone, say calm zone why? because the wind-force that the central shaft plane is above is all stopped and has utilized by the fan blade of angle at 1 to 120 degree, is calm zone thus.But be in this regional leaf blade and also do not have free, be the time period of fan blade flexible rotating 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 is also the reverse side of leaf blade, at wind wheel, fan blade, angle, effect under begin again the stressed power wheel of giving, reason is, because the blade of fan blade is stopped by stressed external frame, the blade of fan blade and inner gimbal present the angle of 60 degree, 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 is exactly such, that is to say wind sail type double-vane wind-power electricity generation wheel, the blade of fan blade when often circling, the capital is subject 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 leaf blade back side is also to the power zone when spending, it is also the wind-engaging zone.
When fan blade forwards 300 to 360 to when spending, fan blade is got back to again the flexible area of fan blade, and blade is not stressed, and the blade of fan blade freely swings with the wind, prepares the running that enters the lower cycle.
Wind sail type double-vane wind-power electricity generation wheel has a plurality of blade link central shafts, and each blade can be spent by flexible rotating 60, around central shaft 360 degree.Blade assembling is between central shaft and framework, and when with the wind, the blade of fan blade reclines on stress frame, and blade angle from 1 to 120 degree when rotating around central shaft, can obtain the thrust of wind.It is stressed that blade in the time of with the wind more than 60% can obtain fine work, and after all vane stress, by stress frame, unification flows to central shaft, after each vane stress, all can drive central shaft, central shaft rotated drive generator set.
