Description
The present invention is with a kind of rectangular vane-type vertical shaft wind mill of wind as the power development wind energy, buoyancy support by water (oil) is rotated around vertical shaft under the effect of wind-force, drive generator by driving mechanism, wind energy is become electric energy, or drive other equipment, change wind energy into other forms of energy.
Existing wind energy engine majority is horizontal shaft type (vertical shaft type is also arranged), generally by fan blade, and compositions such as transverse axis (or vertical shaft), directed rudder.Because the form or the structural reason own of these wind energy engines are difficult to adapt under low wind friction velocity and move, wind resistance evil ability is low, is difficult to develop to hugeization direction, and generate output is little, and is general only between several kilowatts to tens kilowatts.At the seventies, " egg beater " formula (vertical shaft type) windmill of wind energy research center, U.S. Sang Diya laboratory development, generate output reaches 100,000 kilowatt, but this wind energy engine need add external force when starting in addition, the wind-force direction can not keep vertical for a long time with the fan blade face, this body structure of windmill can not improve wind speed and change wind direction, the structure of its shelf and quality limitations to the development of hugeization direction.Reported by the science magazine January nineteen eighty-two, the FD-17 type wind-driven generator of being developed by Heilongjiang Province's mechanical investigations (horizontal shaft type), it is the wind-driven generator of the maximum of the present finding report of China, 20 kilowatts of generate output is, the shortcoming of this wind energy engine is the device that must be furnished with the test wind direction and make the blade commutation, the wind-force direction can not be vertical with the fan blade face, and itself structure can not improve wind speed, changes wind direction.
The objective of the invention is provides a kind of vertical shaft type novel wind power machine that utilizes wind resource with a kind of novel principles, and this wind energy engine mainly is made up of fan blade (1), changed course post (4), vertical shaft (2), buoyancy tank circle (5) etc.
Fan blade (1) profile is a rectangle, its section is that (or semi-fluid is linear for streamline, plate-shaped and garden arc), vertically to being installed on the host rack (8), under the effect of wind-force, fan blade (1) rotates with leaf pivot (6), fan blade (1) upset (wind sheltering) automatically after arriving certain position, be subjected to the restriction of upset limit angular pole (7), fan blade (1) can only turn to several angle, when fan blade (1) automatically reset to the initial position (wind-engaging) that turn round.
The leaf pivot (6) of fan blade (1) can have two leaf pivots of primary and secondary (6,25), and two fan blades of primary and secondary (1,28) are at this moment then arranged, and turns over Ye Shike at fan blade like this and reduces resistance.Leaf pivot (6) can be located at a side or the end points of fan blade center line, and inferior leaf pivot (25) also can be located on the wall of changed course post (4), and time fan blade (28) is attached to changed course post (4) recess place when receiving leaf.Inferior fan blade (28) can be made into telescopic type, in the groove of the post (4) but indentation alters course of time fan blade (28) when receiving leaf.Leaf pivot (6) itself can rotate or not rotate with fan blade.
For the wind energies that get more, also fan blade can be made into the assembling activity type, utilize head lobe pull bar (26) and caudal lobe pull bar (27).Fan blade is opened automatically and draw in by wind-force.This fan blade is made up of main lobe (15), head lobe (16) and caudal lobe (17) three parts, is auspicious streamlined of the aircraft wing after it draws in.No matter be single or assembling activity type fan blade, all can under any wind direction, work.
The fan blade of wind energy engine (1) can be established 4, also can establish 8; If 8 fan blades (1) reduce the fan blade width to the major diameter wind energy engine, many wind energies, and can increase traveling comfort, wind energy engine can be established bilayer or multilayer.
Changed course post (4) is a garden tubular, rotates with fan blade (1) around vertical shaft (2), its role is to change wind direction, thereby improves the wind speed of wind energy engine.When wind to the post that alters course (4) when being obstructed, wind just alters course and is divided into two strands, wherein one wind direction keeps near normal effect (another strand is very fast passing through between changed course post (4) and fan blade (1) face that has become the position) with more time and fan blade face length time, thereby increased the wind-force on the fan blade face, can improve about one times of wind speed.
Vertical shaft (2) can be solid also can be hollow, cast with steel or concrete and all can.When hollow vertical shaft (3) is very high, for reducing the thrust of wind, strengthen its stability, can open all around on vertical shaft top and change window (30), when wind speed is excessive, change window (30) and just open, when a wind speed hour commentaries on classics window (30) is just closed.
Hollow shaft (3) post (4) (be vertical shaft and the changed course post unites two into one) that can replace altering course is then established host rack (8), in addition so that device fan blade (1) outside vertical shaft; Or outside hollow vertical shaft (3), establish steel changed course post (4) in addition.This will increase the stability of wind energy engine greatly, and generator set can be installed in the hollow vertical shaft (3), to save special-purpose factory building.The wind energy that wind energy engine obtained can be imported the generator set that is installed in the hollow vertical shaft (3) into by the power transmission window (19) that is arranged on hollow vertical shaft (3) wall, and this length of normal that imports into is from weak point, and the wind energy frame is not subjected to torsion.
Buoyancy tank circle (5) places in the pond (18) of be filled with water (oil), and by buoyancy of water, the structure weight of support wind energy engine when the wind energy engine operation is rotated, drives buoyancy tank circle (5) and rotates together.Buoyancy tank circle (5) is hollow, garden shape, does not have frontal drag when rotating in water, has only the minimum surface friction drag of side and water.This starts running for wind energy engine designs under hugeization and the low wind speed provide rationale, also created condition for wind energy engine designs wind resistance evil ability.
If necessary, wind energy engine also can be provided with Air System.This Air System is made up of left wind deflector (20), right wind deflector (21) and wind-guiding rudder plate (22), is linked into an integrated entity by the wind-guiding shelf, and device is on buoyancy tank (23) and Air System buoyancy tank circle (24).After wind-force acts on wind-guiding rudder plate (22), Air System is just over against wind direction, left and right sides wind deflector (20,21) changes wind direction, be subjected to wind-force and strengthen owing to wind direction is subjected to the changed course of left and right sides wind deflector (20,21) on fan blade (1) face of left wind deflector (20) one sides (the supposition wind energy engine clockwise rotates), this increasing can improve about 1.5 times of wind speed.In the bigger area of wind-force, when wind power energy satisfies the generate output requirement,, simplify the wind energy engine structure for reducing investment outlay, can not establish Air System.
For the protection generator, at wind energy engine main frame shelf (8) overspeed limiter (10) is set, this limiter (10) is made up of spring (11), upper boom (12), pin (13), by wind-force from line operate.Owing to be subjected to the restriction of overspeed limiter (10); when wind speed is excessive; fan blade (1) pushing overspeed limiter (10); cross limiter (10) and center on leaf pivot (6) rotation until fan blade (1); after fan blade (1) turns to limit angle point (14); fan blade (1) then returns to normal operation position automatically, has so just protected the normal operation of generator.
Utilize the vertical shaft (solid) of wind energy engine of the present invention, fan blade and support can also constitute the sail of seagoing vessel, utilize wind-force to promote the seagoing vessel navigation, with fuel saving.Wind power utilization rate and wind direction are irrelevant.
As seen, the wind energy engine that the present invention provides according to novel principles, relatively simple for structure, generate output is big, and construction, installation, maintenance are conveniently, because the characteristics of wind energy engine self structure, need not to add in addition external force during startup, can work under any wind direction and low wind speed, stability is high, wind resistance evil ability is strong, has created condition for designing hugeization.The more existing wind energy engine generate output of this wind energy engine is big, 150,000 kilowatts of can generate electricity more than.
Task of the present invention be finish in the following manner (see Fig. 1 a): when wind to wind energy engine, after being subjected to the wind-force effect on fan blade (1) face, by the wind energy engine of water (oil) support in pond (18) around vertical shaft (2) rotate (clockwise or counterclockwise direction rotate all can, decide by design.Fig. 1 a is that clockwise direction rotates), when turning to left side B from A, fan blade (1) face parallel with support ring (9) transverse diameter face (coincidence, together following), when being rotated further to back side C, fan blade (1) face is parallel with the vertical diametric plane of support ring (9), at this moment fan blade (1) overturns (wind sheltering) to fan blade (1) face and support ring (9) transverse diameter face perpendicular (D position) automatically around leaf pivot (6), and then is back to original position (A position) wind-engaging effect, and promptly fan blade (1) face is parallel with the vertical face of support ring (9).Wind direction is under the influence of changed course post (4) and wind deflector (when Air System is arranged), and the wind-force action direction turns to back position from initial position, and (when being A～B), most of the time and fan blade (1) face are near vertical, and wind increases makes wind energy engine quickening rotation.Rotatablely move so again and again, drive generator, wind energy is become electric energy by driving mechanism.
