Abstract
The present invention relates to a new-type vertical shaft wind-driven power generator. It includes the following several portions: wind wheel, wind blade shaft, wind blade, wind force regulation wheel, rotary shaft, gear box, rotary wheel, brake device, power generator and tower frame. It is a machine equipment capable of utilizing natural wind force to drive power generator to make power generation. Said invention also provides its working principle and its concrete operation method.
Description
Technical field
The present invention is a kind of machinery of utilizing the wind-force drive generator for electricity generation of nature, especially be provided with on the vertical axis windmill wind apparatus and wind wheel rotated in, returning position after the deflection that blade shaft generation on the wind wheel is 90 °, the size variation when reaching the fan blade windward side.
Background technique
Along with the fast development of human society, the demand of the energy is sharply increased.Original fossil energy reduces day by day, and fossil energy forces people's renewable energy sourcess such as development and utilization wind energy early to the harm that environment caused.At present, many countries have all adopted the generation technology of the horizontal shaft types of upwind three blades in the development and utilization of wind energy, and generated output can reach MW class.Because the fan blade sense of rotation of the horizontal shaft type of upwind three blades is vertical with wind direction, causes wind energy utilization low, shortcomings such as pylon and cost height.But on vertical axis windmill,, at present, do not find to reach the wind-power electricity generation new technology of MW class as yet although form is varied.It is motionless that its reason is that the fan blade of vertical axis windmill in the past is fixed on the wind wheel, and area is little, and resistance is big, and wind energy utilization is low.Because fan blade is fixed on the wind wheel motionless, traditional vertical axis windmill also not to wind apparatus.
Summary of the invention
In order to overcome unmatchful wind apparatus of existing vertical axis windmill and the fixed deficiency of fan blade and China at the face that becomes backward in technique aspect the wind-power electricity generation.The invention provides a kind of vertical axis windmill, this wind energy conversion system can be the wind wheel that rotates in the semicircle fan blade face maximum of rotation, the semicircle fan blade face minimum of rotation against the wind with the wind.When wind direction changes, wind adjustment wheel is also deflected at any time, in time adjust wind wheel, the fan blade on the wind wheel is run well.The enforcement of this vertical axis windmill has been filled up domestic and international vertical axis windmill and need not wind apparatus and the fixed blank of stressed fan blade, has realized that there is the vertical axis wind power generation new technology of independent intellectual property right in China.
The present invention solves the technological scheme that its technical problem takes: a vertical wind energy conversion system is made up of following mechanism from bottom to top, tower mount, pylon, cabin (raising speed gear-box, moving runner, braking brake, generator are arranged in the cabin), the wind direction power servo is arranged on the cabin, to wind adjustment wheel and wind wheel, be connected with 6 identical blade shafts, cam, return spring and fan blades on the wind wheel.Center at a wind wheel is linked to each other up and down with raising speed gear-box power input shaft by rotatingshaft.Be provided with 6 identical blade shafts of five equilibrium extension from inside to outside one week of wind wheel, be connected with identical fan blade on the blade shaft, be provided with identical cam and return spring on the blade shaft in wind wheel.Be provided with the supporting wind adjustment is taken turns below the wind wheel.Be provided with the projecting surface that makes 90 ° of rotations of blade shaft cam on to the semicircle in the wind adjustment wheel, semicircle is provided with and makes the blade shaft cam get back to the concave surface of original position under the effect of spring in addition.When the cam on the blade shaft with wind wheel rotate run into supporting when projecting inward semicircle is taken turns in adjustment to wind, 90 ° of rotations of blade shaft, maximum when the fan blade area is facingd the wind; When the blade shaft cam continues to rotate to against the wind adjustment wheel concave surface, blade shaft and cam under the effect of spring, reverse 90 ° get back to original position, minimum when the fan blade area is rotated against the wind.
When wind direction is constant, motionless to the stall of wind adjustment wheel, be the down wind of blade shaft cam rotation to the protrusion semicircle in the wind adjustment wheel, concave surface be the rotation of blade shaft cam against the wind to.When wind direction changes, to the deflection at any time under the effect of wind transducer and power servo of wind adjustment wheel, adjust the maximum windward side of fan blade and the minimum adverse wind face of fan blade timely, reach the optimum utilization of the steady relatively and wind energy of rotating speed.
The invention has the beneficial effects as follows: because wind wheel and fan blade are the substantially horizontal rotations, at the bottom of the pylon, blade structure is simple, and is little to the wind direction power servo of wind adjustment wheel preparation, so the present invention is simple in structure, and cost is low.Fan blade is many, fan blade is long, area is big, and stress surface is vertical again with wind direction; The stress surface of fan blade diminishes in the time of against the wind, and the wind wheel rotational resistance is little.Therefore, the wind energy utilization height, generated output is big, can realize MW class.Secondly, China's energy shortage, wind resource is abundant, owing to introduce the traditional wind generating technology of other country, cost height, the development and utilization of serious obstructor China wind energy.
