Description
Technical field
The present invention relates to vertical axis aerogenerator, refer to a kind of power constant output device that is applied to vertical axis aerogenerator especially.
Technical background
For the better utilization wind energy, for a long time, people have designed the wind generating unit of multiple structural type, according to the difference of wind-driven generator running shaft in the direction in space position, are divided into the horizontal axis wind-driven generator of substantially horizontal and the vertical axis aerogenerator of Vertical direction.
Generally speaking, the wind wheel of vertical axis aerogenerator adopts has certain wing prismatic blade formation, and the axis of blade is parallel with vertical shaft.The wing of blade can obtain according to existing aerodynamic principle design.According to aerodynamic principle, the line of blade front and rear edges is called as the string of a musical instrument, and the corner of a certain position tangent line is a blade rotating angle on the string of a musical instrument of blade and the circumference.These blades generally are fixedly installed on cantilever supporting wing (cantilever support) or ring-like support that vertical shaft rotates, as shown in Figure 1.When the wind of certain intensity have at these necessarily wing, and and the tangent line of running shaft when forming on the prismatic blade of several angle, just on these blades, produce the moment of rotating and make whole wind wheel rotation around vertical shaft.
The rotating speed of vertical axis aerogenerator wind wheel is subjected to the influence of blade rotating angle size, when blade rotating angle reduces, wind speed round increases; When blade rotating angle increased, wind speed round reduced.And be the vertical axis aerogenerator of blade rotating angle fixed for prior art, its wind speed round is directly proportional with ambient wind velocity, and promptly under certain blade rotating angle condition, when ambient wind velocity increased, then wind speed round also increased thereupon.According to aerodynamic principle as can be known, cube being directly proportional of wind energy and wind speed, when wind speed when 10 meter per seconds increase to 25 meter per seconds, its wind energy has increased nearly 16 times.Therefore just need to select more powerful generator and wind wheel coupling selecting for use of vertical axis aerogenerator, make vertical axis aerogenerator under higher wind speed, keep working state.But thus, the rated wind speed of vertical axis aerogenerator will certainly be designed very high, but consider from the characteristic of generator itself, generator for high rated wind speed, its efficient when hanging down wind speed is just very low, and under the general nature condition, all be the environment that is in low wind speed in the time of most, therefore above-mentioned design proposal can reduce the efficient of vertical axis aerogenerator on the contrary.
Summary of the invention
At the technical problem that exists in the above-mentioned existing vertical axis aerogenerator power output, make vertical axis aerogenerator under the situation of wind speed excursion broad, remain specified output power, make wind wheel after wind speed surpasses rated wind speed, still keep more constant rotating speed.Reach vertical axis aerogenerator under the situation of wind speed excursion broad with this, remain working state, improve its using value.
The concrete technological scheme of the present invention is as follows:
The structure of this device comprises blade 1, rocking arm 3, rotating shaft 4, cantilever support 5, spring 6; Described rocking arm 3 is connected with cantilever support 5 by rotating shaft 4, but rocking arm 3 serves as the rotation of axle along continuous straight runs with rotating shaft 4; Rocking arm one end 31 fixedly connected blades 1, the rocking arm the other end 32 is fixedlyed connected with spring one end 61 on being located at cantilever support 5.
Above-mentioned cantilever support 5 moves and spacing groove 51 being provided with for this rocking arm the other end 32 with the rocking arm the other end 32 corresponding positions.
The above-mentioned rocking arm the other end 32 is provided with protuberance 33 and can moves in the set groove 51 of cantilever support 5.
Above-mentioned rocking arm 3 moves at cantilever support 5 set grooves 51, and the corner excursion that drives blade 1 is 0～30 degree.
The above-mentioned spring the other end 62 can be fixed on the cantilever support 5.
The above-mentioned spring the other end 62 can be fixed on the vertical shaft axle sleeve.
The present invention will reach embodiment in conjunction with the accompanying drawings below and be described.

Embodiment
Can further be well understood to the present invention by specific embodiments of the invention given below, but they not limitation of the invention.
Embodiment 1:
As shown in Figure 1, 2, 3, be power constant output device for wind-driven generator with vertical shaft embodiment's 1 of the present invention structural representation respectively.The structure of this device is formed with blade 1, blade bearing 2, rocking arm 3, rotating shaft 4, cantilever support 5, spring 6.Described rocking arm 3 is connected with cantilever support 5 by rotating shaft 4, and rocking arm 3 can rotating shaft 4 be the rotation of axle along continuous straight runs; Described rocking arm one end 31 connects blade bearing 2, blade 1 is installed on the blade bearing 2; the rocking arm the other end 32 can slide in the set chute 51 of cantilever support 5, and the described rocking arm the other end 32 is fixedlyed connected with an end 61 of spring, and the spring the other end 62 is fixed on the cantilever support 5.Behind physics measuring and calculating buoyancy and rotary inertia, select the spring of suitable elasticity coefficient, under the driving of wind wheel blade, rotate at wind-force, and when making wind wheel reach certain rotating speed, under the force action along with suffered aerostatic buoyancy of blade and centrifugal force, the pulling spring makes the rocking arm the other end 32 slip in the set chute 51 of cantilever support 5, rocking arm 3 is the rotation of axle along continuous straight runs by rotating shaft 4 simultaneously, blade 1 deflection on the blade bearing 2 that drive rocking arm one end 31 connects, thereby wind speed change blade and the angle of the string of a musical instrument, i.e. blade rotating angle by wind wheel.Learn that by experiment when blade rotating angle was big, resistance that blade is suffered and flow-disturbing effect were also big more, the rotating speed of wind wheel is then lower; Promptly along with blade rotating angle increases, the rotating speed of wind wheel reduces.Therefore when generator loading is constant,,, make wind speed round constant, promptly keep ambient wind velocity wind speed round constant after raising by controlling the increase of wind wheel blade corner along with the increase of ambient wind velocity.
Present embodiment is chosen the Goe364 airfoil fan, 1.36 meters of rotor diameters, the rated wind speed of setting vertical axis aerogenerator is 9 meter per seconds, when 10 meter per seconds were increased to 15 meter per seconds, corresponding respectively test was at the generated output power that does not adopt under apparatus of the present invention and the situation that adopts apparatus of the present invention at ambient wind velocity.Shown in following table and accompanying drawing 4, along with the increase of ambient wind velocity, under the condition of using apparatus of the present invention, the output power of generator changes to 148 watts from 135 watts; Under the condition of not using apparatus of the present invention, the output power of generator is increased to 478 watts from 130 watts.
| Wind speed (meter per second) | 10 | ?11 | ?12 | ?13 | ?14 | ?15 |
| Power when installing without this (watt) | 130 | ?175 | ?245 | ?305 | ?390 | ?478 |
| Power when using this device (watt) | 135 | ?137 | ?138 | ?140 | ?145 | ?148 |
By above-mentioned experiment as can be known, when the wind speed excursion is increased under the situation of 15 meter per seconds by 10 meter per seconds, use the wind-driven generator of apparatus of the present invention, wind wheel still can keep more constant rotating speed after wind speed surpasses rated wind speed, and engine output remains at state stably.Improved the using value of vertical axis aerogenerator greatly with this.
Although the present invention has been done detailed explanation and has quoted some specific embodiments as proof, to those skilled in the art, only otherwise mentality of designing and the scope of leaving the inventor can be obvious as various changes and modifications also.
