Multiplying gear carries out transmission speedup instead of traditional gear-box, avoids the occurrence of gear box structure transmission efficiency and lowly, easily grinds
Damage, the defects of cost is high.
The concrete operating principle of this four machine control techniques is as follows：
One, the operation principle without electric-controlled mechanical from motion tracking wind direction is：Due to the cantilever-shaped horizontal part 13 of rack and vertical
Portion 6 can be rotated freely around 2 level of vertical shaft simultaneously, then entire impeller is located at the cantilever end of horizontal part 13；Therefore, be based on vertical shaft 2 with
The impeller being installed in impeller axle 14 can be considered as two semicircles, the blade 31 of the two semicircles by the vertical basal plane of impeller axle 14
Just the arm of force is formed with the vertical shaft at vertical center 2.When the Plane of rotation out of plumb of wind direction and blade 31, the blade wind-engaging of two semicircular
Power is different, and horizontal rotation can be stopped around the rotary power of vertical shaft 2, when the blade 31 of two semicircular is identical by wind-force by just foring
Turn, wind direction is to blow to impeller by vertical shaft 2, and wind direction is vertical with the Plane of rotation of blade 31 at this time, and impeller axle 14 is flat with wind direction
Row.
Two, the operation principle of the steady rotating speed of machine automatization/frequency stabilization output electric energy is：After impeller is directed at wind direction, wind energy passes through
Impeller is changed into rotating mechanical energy, and is transmitted to level-one chain wheel 10 by impeller axle 14, then is passed successively by train speedup sequence
It is delivered to generator sprocket wheel 5, this rotating mechanical energy can also be synchronized by shaft coupling 3 and be passed to while passing to generator 4
Oil pump 26；Oil pump obtains rotating mechanical energy at this time, can suck hydraulic oil from fuel tank 25 by fuel sucking pipe 15 in rotation, the liquid
Pressure oil becomes pressure oil after oil pump 26, and pressure oil enters pressure using pressure oil core pipe 24, pressure oil export 23 and floats
In the pressure chamber 37 of body 22, measures hydraulic fluid port 21 finally by current stabilization and come back in fuel tank 25, i.e., make under the action of oil pump 26
It obtains hydraulic oil and forms circulation loop.
After current stabilization measures the flow setting of hydraulic fluid port 21, when wind speed power generation wind speed minimum higher than wind-driven generator, it can lead
The pressure of the oil outlet and pressure oil core pipe 24 that cause oil pump 26 increases, then the flow velocity of pressure oil export 23 and flow have increase to become
Gesture, i.e., when oil pressure is higher than its gravity or spring pressure in the same direction in the pressure chamber 37 of pressure buoyancy body 22, because speed adjusting lever 20 with
The 37 upper end area of pressure chamber that pressure buoyancy body 22 combines is more than the 37 lower end area of pressure chamber of pressure buoyancy body 22, so increasing
Oil pressure afterwards will push pressure buoyancy body 22 to rise overally, the pressure on the diameter hollow column tube lateral surface of pressure oil core pipe 24
Power oil export 23 reduces its discharge area by pressure buoyancy body 22 with cut mode so that the flow of pressure oil export 23 is always
The flow that hydraulic fluid port 21 is measured with current stabilization is equal, i.e., hydraulic oil circuit flow remains stable, and the rotating speed of oil pump 26 can also be protected
It is fixed to keep steady.Conversely, when oil pressure is less than its gravity or spring pressure in the same direction in the pressure chamber 37 of pressure buoyancy body 22, with pressure
The area of the decline of buoyancy body 22, pressure oil export 23 increases, but the flow of pressure oil export measures hydraulic fluid port 21 with current stabilization always
Flow it is equal.When measuring the area of hydraulic fluid port 21 and if only if current stabilization and changing, hydraulic oil circuit flow turns with oil pump 26
The fast variation that is also proportionate therewith.
Therefore, when extraneous wind speed is higher than minimum electrical power generators wind speed, the damping action of hydraulic system makes entirely to be driven
System rotating speed does not change, and the pressure of the oil outlet of oil pump 26, oil pipe 11 and pressure oil core pipe 24 is only made to change.Especially
It is that, when the rotating speed of the rotating speed of oil pump 26 to be changed and generator 4, speed adjusting lever 20 need to be adjusted and measure hydraulic fluid port 21 to change current stabilization
Area, to realize adjusting to rotating speed.
The flow control principle formulae express of hydraulic circuit system is as follows：
When, pressure buoyancy body 22 rises, and the area of pressure oil export 23 is reduced, and flow is reduced；
When, pressure buoyancy body 22 is static, and flow and the current stabilization of pressure oil export 23 measure hydraulic fluid port 21
Flow is equal；
When, pressure buoyancy body 22 declines, and the area of pressure oil export 23 increases, and flow increases；
Wherein,
P is the fluid pressure of pressure chamber 37 in pressure buoyancy body 22, kg/cm2；
A is the 37 upper end area of pressure chamber of pressure buoyancy body 22, cm2；
B is the 37 lower end area of pressure chamber of pressure buoyancy body 22, cm2；
G is the gravity of pressure buoyancy body 22, kg；
By above-mentioned current stabilization amount hydraulic pressure revolution speed control device, in the case where wind speed changes, oil pump 26 can also be realized surely
Determine rotating speed.When power generation wind speed minimum less than design, pressure buoyancy body 22 drops to bottom, and pressure oil export 23 opens maximum, whole
Covering revolution speed control device will be out of hand to fluid flow, is also simultaneously stopped electricity consumption.
Three, the chain wheel multiplying gear that the utility model uses, the transmission speedup principle and conventional gear being related to
It is identical to be driven speedup principle, specially：Sprocket wheel related to chain wheel transmission is simple chainwheel, the with three row's bushroller chains 9
Two rows engage, and chain wheel and related sprocket wheel pitch circle are tangent, are passed in the tangent position of big steamboat pitch circle by three row's bushroller chains 9
Graduating energy, the gear teeth of chain wheel do not contact with the gear teeth of related chain wheel, only transmit kinetic energy by chain, accordingly can be applied to multistage
Chain wheel gear.
Four, the operation principle of machine automatization control impeller torque is：The utility model is related to hydraulic system in, oil pipe
11 communicate with the oil outlet of oil pump 26, and hydraulic fluid pressure is transmitted to the plunger 33 of torque controller by oil pipe 11, and then pushes
35 compressed spring 34 of top cover is slided, so that a pair of of friction plate 36 is adjacent to torque plate 16, generated frictional force reduces torque plate
Torque, but its rotating speed is not influenced.Since the torque of torque plate 16 reduces, the pressure of oil pump 26 is caused to decline, while in spring 34
Under the action of, and a pair of of friction plate 36 is made to leave torque plate 16.Therefore, it can avoid the torque for leading to impeller since wind speed is excessive
Greatly, to cause the damage to transmission system, hydraulic pressure speed stabilizing system and generator, the i.e. not requirement of survival wind speed, three-level
