Description
Technical field
The present invention relates to vertical axis aerogenerator, refer to a kind of blade rotating device that is applied to vertical axis aerogenerator especially.
Background technique
Wind-driven generator claims windmill again, is a kind of energy conversion device that wind energy is converted to mechanical energy, electric energy or heat energy.Difference by rotor shaft can be divided into horizontal-shaft wind turbine and vertical axis windmill.Energy drives chain (being wind wheel, main drive shaft, speedup box, generator) is referred to as horizontal-shaft wind turbine in horizontal direction.The energy drives chain becomes vertical direction, is referred to as vertical axis windmill.Vertical axis aerogenerator can be divided into resistance type and lift-type two classes.
In the prior art about utilize wind energy, solar energy with and the open report of the electricity generating device of combination more.But the wind wheel of general vertical axis aerogenerator adopts lift-type, the blade shape complexity, and manufacture cost is higher, and the axis of blade is parallel with vertical shaft, and the rotation of wind wheel and wind direction are irrelevant, therefore do not need to adopt as horizontal-shaft wind turbine wind plant.But because the fixed angle of blade and cantilever support is constant, therefore, the size and Orientation of the driving moment that blade produces is constantly to change, also can produce bigger resisting moment simultaneously, so the startup wind speed of existing vertical axis aerogenerator is big and wind energy utilization is not high, environmental suitability is not strong.
Summary of the invention
The object of the present invention is to provide a kind of attack angle of blade can regulate, the wind energy utilization that can improve generator and adaptive capacity to environment and reduce the adjustable angle of attack MW class vertical axis aerogenerator that starts wind speed.
The object of the present invention is achieved like this:
It comprises power inverter, speedup box, generator, change oar motor, main vertical shaft, cantilever tube, cantilever beams, blade; It is characterized in that: main vertical shaft is outer to connect the cantilever tube by bearing, and cantilever beams one end is fixed on the cantilever tube, and the cantilever beams the other end is provided with the blade rotating device, and main vertical shaft top is provided with lightning conductor, wind vane and anemoscope; The blade rotating device is power resources with the storage battery; Electric control device transmits signal and gives blade rotating device, the rotation of blade rotating device drive vane; The composition of described blade rotating device comprises the blade pitch device that becomes oar motor, worm speed-down case, band self-locking; Become the oar motor and be installed on cantilever beams one end, become the oar motor and link to each other with the input shaft of worm speed-down case, the output shaft of worm speed-down case links to each other with the blade pitch device of band self-locking, and the output shaft of the blade pitch device of band self-locking links to each other with sharf; The Ac of generator output is directly imported electrical network after the commutation inversion device is handled; The blade rotating device is power resources with the battery pack.
The present invention can also comprise some features like this:
1, between cantilever tube and the main vertical shaft ultra-low friction coefficient liquid-bearing and thrust roller bearing are installed, cantilever tube gear ring is fixed on the cantilever tube, and generator gear is installed on the generator shaft, and cantilever tube gear ring links to each other with generator by speedup box.
2, on every group of cantilever beams 2 change oar motors are installed, control the blade spinning motion simultaneously.
3, cantilever tube and cantilever beams are fixed together, and can rotate around main vertical shaft by ultra-low friction coefficient liquid-bearing and thrust roller bearing.
4, sharf is set in the place, pressure center of blade.
The present invention in the course of the work, the wind direction and wind velocity numerical value that can feed back to according to wind vane and anemoscope is by electric control device control blade spinning motion, the angle that facings the wind of adjusting vane effectively.
The blade rotating device can rotate on horizontal plane with respect to the cantilever beams of its connection, for making blade consumed energy in rotary course minimum, sharf is arranged on the place, pressure center of blade, a motor overcome friction acting, and the motor power loss is less.
The present invention adopts the vertical axis windmill form, and the angle that facings the wind of adjusting vane makes blower fan be in the state that produces maximum moment all the time automatically, effectively reduces and starts wind speed.
The obtained technological progress of the present invention is:
1, main vertical shaft and cantilever beams all can adopt steel frame construction, not only make things convenient for to produce, transport, and install easily, dismantle, and easy maintenance reduces operating cost greatly.
2, attack angle of blade can be adjusted voluntarily according to the wind speed and direction information that collects.When the speed of the wind comes from hour, sharf rotates in 90 ° of scopes, and blade all is near the angle of attack scope of maximum lift at an arbitrary position, blade can produce the driving moment of maximum; Big when the speed of the wind comes from, when generated output is too high, blade can be rotated to the angle of stalling point, reduces generated output, avoids the generator overload; When typhoon came, blade rotated to downwind position, reduced wind-exposuring area, avoided pylon to produce huge lateral thrust.
