Description

A kind of wind turbines rotor automatically becoming fan blade pitch vane angle according to wind-force
Technical field
The present invention relates to a kind of wind power generator wind wheel, a kind of wind turbines rotor automatically becoming fan blade pitch vane angle according to wind-force.
Background technology
In short supply now with the energy, increasing green energy resource is paid close attention to by people, such as solar electrical energy generation, it has the problem of generating when of only can having sunshine by day, the most also remain some technical bottlenecks, the conversion of high efficiency electric power cannot be realized, and it is still needed aborning and to consume the substantial amounts of energy, therefore also cannot extensively carry out at present.Sight has been invested wind-power electricity generation by people again now, as long as no matter day and night has wind just can work for it, the larger wind power plants having many at present is set up, but the fan blade of current wind-power electricity generation there is problems in that, it is contemplated to prevent fan blade ultrahigh speed in strong wind from rotating, again in order to turn to certain rotating speed in the case of wind-force is less, the pitch vane angle of its fan blade have selected the numerical value mutually taken into account, but still also exist and just cannot work less than moderate breeze, more than storm it is possible to fracture fan blade or fan blade overspeed rotation, often really can only generate electricity within the limited time period for this present wind-driven generator, waste the time that cannot generate electricity in a large number, the most existing fan blade is improved, to realize the novel wind generator wind wheel that the little wind of strong wind all can normally work.
Summary of the invention
Present invention aim to address the problems referred to above existing for prior art wind electromotor fan blade, it is provided that a kind of wind turbines rotor automatically becoming fan blade pitch vane angle according to wind-force.The present invention designs a kind of wind turbines rotor automatically becoming fan blade pitch vane angle according to wind-force, if including dry tablet fan blade, main shaft, rim, it is characterized in that: rim is arranged on a sleeve, sleeve is slidably connected on main shaft, by keyway and bonded between sleeve and main shaft, return spring is installed between sleeve and main shaft, each fan blade is arranged on rim by a rotating shaft, fixing connection one poke rod in rotating shaft, at the rear portion of main shaft, one retainer ring is installed, retainer ring is provided with some top pull bars, every top pull bar is arranged in retainer ring by universal joint, the poke rod in rotating shaft that each fan blade is installed is connected by universal joint with between top pull bar.It is characterized in that: have a connection ring, connect and have pivot pin to connect the outer end of every fan blade on ring.It is an advantage of the invention that the wind-power electricity generation can taken into account under strong wind and mild wind state, enable fan blade to generate electricity in broad wind ranges.
Accompanying drawing explanation
Accompanying drawing 1 is the section of structure of the present invention, and Fig. 2 is the schematic diagram that fan blade front face area of the present invention is minimum, and Fig. 3 is the schematic diagram that fan blade front face area of the present invention is maximum.
Detailed description of the invention
If figure includes dry tablet fan blade 1, main shaft 2, rim 3, it is characterized in that: rim is arranged on a sleeve 4, sleeve is slidably connected on main shaft, connected by keyway 5 and key 6 between sleeve and main shaft, return spring 7 is installed between sleeve and main shaft, each fan blade is arranged on rim by a rotating shaft 8, fixing connection one poke rod 9 in rotating shaft, one retainer ring 10 is installed at the rear portion of main shaft, retainer ring is provided with some top pull bars 11, every top pull bar is arranged in retainer ring by universal joint 12, the poke rod in rotating shaft that each fan blade is installed is connected by universal joint 13 with between top pull bar.It is characterized in that: have a connection ring 14, connect and have pivot pin 15 to connect the outer end of every fan blade on ring.
nullIn installation,When return spring stretches with the non-stress of torsion return spring,The pitch vane angle of fan blade is adjusted to maximum,As long as now there being little wind to occur,Owing to fan blade front face area now is maximum,Fan blade can be blown by the least wind-force,Meet the rotation of fan blade required for the wind-driven generator under little wind state,When after wind increases,The fan blade of big front face area can be by big pressure,Now fan blade will press return spring under drive sleeve,Along with sleeve moves down,Poke rod in fan blade rotating shaft is by the top power of top pull bar,Make fan blade axis of rotation,Thus the pitch vane angle changing fan blade is turned down,Now windward side suffered by fan blade diminishes,Pressure experienced also diminishes,When reaching the dynamic equilibrium of return spring and fan blade institute stress,The pitch vane angle of fan blade is stable,Now fan blade stable rotation speed,The biggest rotating speed will not be produced,Meet the work of wind-driven generator.After wind-force reduces, wind-force suffered by fan blade also diminishes, return spring pushes back past for sleeve, along with sleeve pushes back, the pitch vane angle of fan blade, by the pulling force of top pull bar, is now tuned up again by the poke rod in fan blade rotating shaft, makes the front face area of fan blade increase, thus ensure fan blade stable rotation again, so that fan blade slow-roll stabilization in bigger wind ranges.
