Background technology
Technical field of wind power uses oar blade type wind energy conversion system both at home and abroad at present, and the aerodynamics of blade confirms that blade is caught
The effect for obtaining wind energy is very limited, may ideally be captured in the wind energy of maximum 59% (theoretical value), practical application only
40~50% can be reached, here it is blade wind power technology is difficult to develop the main cause of powerful device.
The way for obtaining wind energy using sail is with a long history, although the naval vessel of modernization instead of ancient sailing boat,
Be sail capture wind energy unique efficiency really blade can not be compared, known by the aerodynamics of sail, when wind is acted on
During sail, the windward side of sail is by very big thrust, and when wind flows through sail at a high speed, the pressure of its lee face can reduce and produce
Suction, its suction is very large, is twice than windward side by the strength that wind is pushed away, and equivalent to the thrust for obtaining three times, sail is such as
The characteristics of this efficient capture wind energy, exactly we dream of using wind energy resources.
The main task of the present invention is exactly that the linear motion for producing sail under wind-force effect is transformed into constant
Rotary motion, design high-power, dynamical rotation sail type wind machine.
The content of the invention
1. revolve sail technology
Rotation sail technology has been invented, sail leaf has been fixed in revolution main body, the windward side of sail is right against wind direction, when by wind-force
When will promote revolution main body rotation, in order that sail leaf is windward or wind sheltering, sail leaf can revolve or backspin on sail axle, to adjust sail leaf
Windward angle.
Purposes：The linear motion that sail is produced by wind-force is transformed into the rotary motion of revolution main body.
Sail impeller structure：(such as accompanying drawing) is designed for flag-shaped, sail axle is fixedly connected with sail leaf, be effective capture wind energy, sail leaf is set
Count into circular arc camber.
2. revolve the operation principle of sail type wind machine
Imagination crosses the axis of wind energy conversion system, draws straight line as line of demarcation relative to wind direction, sail leaf when wind energy conversion system is rotated
The formation circle of distal end, is divided into the region of front, rear, left and right four.
It is A transition regions and B transition regions to set near the front and rear sides of line of demarcation, and into A transition regions, the windward side of sail leaf occurs
Change, be changed into front windward from the back side windward, sail leaf is taken advantage of a situation backspin around sail axle, by horizontality gradually transition and conversion into vertical configuration
State.Into B transition regions, the windward side of sail leaf is changed again, and the back side is changed into windward windward from front, on sail leaf is taken advantage of a situation around sail axle
Rotation, by plumbness gradually transition and conversion into horizontality.
Left region is set as the wind sheltering area of sail leaf, the sail leaf for rotating into the region is adjusted and keep horizontality, this
Sample sail leaf front face area is minimum, and the wind-force being subject to is also minimum.
Right area is set as the area windward of sail leaf, the sail leaf for rotating into the region is adjusted and keep plumbness,
So sail leaf front face area is maximum, and the wind-force being subject to is also maximum.
Due to the wind-force serious unbalance being subject in area windward and wind sheltering area sail leaf, ideal revolving force just can be formed
Square, sail leaf can promote the lasting rotation in one direction of revolution main body naturally.
3. key technology
Realization principle has two key links, i.e. sail leaf is converted into vertical state by horizontal state, then is converted into water by vertical state
Flat state, sail leaf will complete a posture changing when often turning 180 ° around axis.Key technology, utilizes wind when being exactly sail leaf posture adjustment
Comprehensive function when power, sail leaf gravity and wind energy conversion system rotation to inertia force, centrifugal force produced by sail leaf, through sail leaf posture
Adjuster regulation positioning is realized.
4. important technology explanation
Sail leaf attitude adjuster be revolve sail type wind machine important devices, as a proprietary technology in this manual only
Its function is introduced, structure and principle is not introduced.
Sail leaf attitude adjuster has three functions, first, completing the posture conversion regulation of sail leaf normal course of operation.Its
Two, when wind speed is too fast, during beyond normal value, can timely adjustment sail leaf windward side angle, reducing blast ensures wind energy conversion system safety
Operation.Third, when there is super strong wind, all sail leaves being adjusted to horizontality, windward side is minimized, kept away with safety
Wind.
5. the beneficial effect that the present invention is brought
1. rotation sail type wind machine designs for vertical axis, is not influenceed during work by wind vector, with existing horizontal-shaft wind turbine
It is simpler, safe and reliable compared to designing.
2. the efficiency for converting wind energy into mechanical energy due to sail leaf is very high, and the bar of performance is met in sail impeller structure and material
Under part, its front face area can be done to the greatest extent greatly, with the increase of sail number of sheets amount, and wind transformation of energy scale will have very big development empty
Between, so, technical support will be provided for Future Design manufacture superpower wind energy conversion system, be expected to China or even world's wind-powered electricity generation cause
Produce material impact.
6. experimental verification
The small test machine manufactured by above-mentioned principle has completed experimental verification, it was demonstrated that the operation principle section of rotation sail type wind machine
Learn reasonable, wind energy conversion system rotation is steady, and sail leaf attitude regulation is smooth.
Brief description of the drawings
The fundamental diagram of accompanying drawing-rotation sail type wind machine
Unit number：
-- (1,2,6,8) turn round main body -- 3 sail rachises -- 4 sail leaf attitude adjusters -- 5 pedestal -- 7 to sail leaf
Wind energy conversion system is divided into the region of front, rear, left and right four relative to wind direction, i.e.,：A transition regions, B transition regions, wind sheltering area and meet
Wind area.
State description of the sail leaf in each region
When sail leaf 1 is rotated to B transition regions, the windward side of sail leaf changes, and is changed into the back side windward windward from front, in wind
In the presence of power, inertia force and centrifugal force, as shown in arrow, gradually on be threaded to horizontality.
Sail leaf 2 rotates into wind sheltering area and keeps horizontality, the acceptable minimum wind energy of this state front face area minimum.
When sail leaf 8 is rotated to A transition regions, the windward side of sail leaf changes again, is changed into front windward from the back side windward,
In the presence of wind-force and sail leaf gravity, as shown in arrow, take advantage of a situation and be gradually threaded to plumbness down.
Sail leaf 6 rotates into area windward and keeps vertical state, the maximum acceptable most wind energy of this state front face area.
Due to the wind-force serious unbalance being subject in area windward and wind sheltering area sail leaf, ideal revolving force just can be formed
Square, sail leaf can promote the lasting rotation in one direction of revolution main body naturally.
Embodiment
