Background technology
Contradiction between the trend that mankind's demand growing for the energy and ecological environment day by day deteriorate so that how
Realize the sustainable use of the energy and the whole world is developed into all in the problem of concern.For China, changing China with coal is
The industrial structure of main energy resource structure and high pollution high energy consumption is China Environment control and tackles compeling for Global climate change
Highly necessary ask.
Wind energy receives the attention of countries in the world as excellent clean energy resource.The wind-driven generator for using at present is usual
Including wind wheel, machine driven system (such as speed increaser etc.) and generator etc..Wind wheel rotates under the action of the forces of the wind, and what is obtained is dynamic
Energy Jing machine driven systems pass to generator, convert kinetic energy into electric energy by generator.Machine driven system and generator quilt
It is encapsulated in a cabin, tower top is arranged on by rotary supporting device then, the head of wind-driven generator is constituted.Machine
Head, the head of particularly big-and-middle-sized wind-driven generator, its weight are very big, can reach tens of tons to hundreds of ton.Therefore, to turning
The requirement of dynamic supporting arrangement is high, and the manufacturing cost for causing rotary supporting device is high.Heavy head needs special machine
Tool surveys wind and to wind apparatus, further increases volume, weight and the structural complexity of head.The weight and volume of head is to fortune
Defeated and installation also brings many difficulties.
On the other hand, as generator is arranged in the cabin of rotation with the wind, the cable for outwards transmitting electric power may
The phenomenon of twisting can occur, so wind-driven generator also needs to install and untying the mooring rope accordingly and turning round cable protection device.It can be seen that, it is current
Wind-driven generator structure is complicated, very big in the cost of the aspects such as manufacture, transportation, installation, maintenance, becomes obstruction wind energy extensively sharp
One of factor.
In addition, compared with traditional thermal power generation, hydroelectric generation, nuclear energy power generation, wind-power electricity generation is unstable because of air quantity, have
The problem of intermittent electric power.And the wind for flowing can not be stored as coal, water, nuclear fuel in advance, therefore wind-power electricity generation Jing
Often do not match that with the power consumption of electrical network, such as during peak of power consumption on daytime but wind-force is weak, generated energy is few, during night low power consumption but
Wind-force is strong, generated energy is more, brings extra difficulty to dispatching of power netwoks.One of current settling mode is by wind-power electricity generation and firepower
Generating etc. combines, and supplies mutually, but extra burden is but caused to thermal power generation.Another advanced settling mode exists at present
In wind-powered electricity generation and CAES (Compressed Air Energy Storage, Caes) technology being combined, by wind-force
Generator is converted to compressed air by the electric energy that cable transmission is got off and can store, then when needed by compressed air energy
Electric energy is converted into, electrical network is supplied, but its efficiency is relatively very low.
Figure 1 illustrates a kind of flow chart of relatively advanced wind-driven generator in prior art.Wind-driven generator profit
Wind wheel blade rotation is driven with wind-force, then the speed for rotating is lifted by booster engine, promote electrical power generators, generator institute
The electricity for sending is conveyed to motor after commutation inversion, then stores up the electric energy produced by wind-driven generator using CAES technologies
Compressed air energy is saved as, when needed compressed air-driven rotating turbine, drive electrical power generators, compressed air can be changed
For electric energy, electrical network is uploaded to.But, the efficiency of this wind-driven generator is very low, though under optimum, from generator to
The efficiency of AC/DC/AC links is about 85%, AC/DC/AC and is about 89% to the efficiency of motor link, from motor to CAEC
The efficiency of link is about 85%, only these links loss just up to 37%.

Tool can be by means of constituting by the bent axle in the head, installed in tower body inner carrier, the piston rod between bent axle and piston
Power-transmission system is transferred to a position output of tower body.But its power-transmission system has very big defect.One
Aspect, because wind-force it is unstable, when it is big when it is little, if will ensure that bent axle can successfully turn over upper dead center position in wind-force hour
(this position potential energy maximum, minimum of kinetic energy), needs to give crankshaft installed flying wheel, but does not have within the system to install inertia
The space of wheel.On the other hand, when bent axle drives piston movement, whole system is not buffered, and the downward impulse force of piston is very big, causes
It is very big to the impulse force of head bearing and tower body.
Patent document CN102619699A discloses a kind of wind power generating set and a kind of kinetic energy edge for producing wind wheel

Describe in detail as follows：
Working condition one：
The power transmission of dual input merging-piece-rate system when Fig. 3 shows only tail vane wind wheel is not rotated as input
Path.At this moment, can adjust the direction windward of wind wheel.
In the case, tail vane 10 drives machine head base rotation, for example, rotated with the direction shown in arrow in Fig. 3, and led to

First semiaxis 51；As shown in phantom in Figure 3, the rotation of the axle 45 of second bevel gear 42 is via second bevel gear transmission mechanism 7
The bevel gear 71 of horizontal positioned, the bevel gear 72 of the vertical placement of second bevel gear transmission mechanism 7, are transferred to the first differential mechanism 5
The second semiaxis 52.
As shown in figure 3, the motion of tail vane is via two parallel bang paths (bang path shown in solid line and dotted line)
It is transferred to first semiaxis 51 and the second semiaxis 52 of the first differential mechanism 5.By this two parallel bang paths so that first is poor
Rotary speed at first semiaxis 51 and the second semiaxis 52 of fast device 5 is equal, in opposite direction.6 He of first bevel gear transmission mechanism
The gear ratio of second bevel gear transmission mechanism 7 may be selected to be it is identical, thus in first semiaxis 51 and the second half of the first differential mechanism 5
Rotary speed size at axle 52 is identical.According to differential mechanism operation principle formula：
2n0=n1+n2
Wherein, n0Represent the rotating speed of differential casing, n1Represent the rotating speed of the first semiaxis, n2Represent the rotating speed of the second semiaxis.
Because the direction of rotation at the first semiaxis 51 and second semiaxis 52 of the first differential mechanism 5 is contrary, size is identical, also
That is n1=-n2, therefore deduce that n0=0.When only tail vane as input drive head rotate and wind wheel do not rotate when, the
Zero is output as at one differential casing 53, i.e., essence is not exported.

First semiaxis 51 of device 5 is identical with the rotary speed direction at the second semiaxis 52.In addition, as described above, first bevel gear transmission
The gear ratio of mechanism 6 and second bevel gear transmission mechanism 7 may be selected to be it is identical, thus in the first semiaxis 51 of the first differential mechanism 5
It is identical with the rotary speed size at the second semiaxis 52.
According to differential mechanism operation principle formula 2n0=n1+n2, it can be deduced that n0=n1=n2.When only wind wheel is rotated as defeated
Enter end to rotate and tail vane when not driving head to rotate, the first differential casing 53 rotates, and has substantive output herein.
Working condition three：
In practice, wind-force drive wind wheel rotation and tail vane drive head rotating be can be simultaneous, for example, in wind-force
When driving wind wheel to rotate, yaw system such as tail vane adjusts the direction of head simultaneously, makes wind wheel all the time in state windward.Now,
Two kinds of motion states as described in situation one, situation two are present simultaneously, and two kinds of motion states are superimposed, but which has no effect on situation
Essence transmission result described in two.Thus, two inputs, an output are realized using same mechanism, the input of tail vane is the
Zero is output as at one differential casing, the input of only wind wheel causes the essence output at the first differential casing.
Here, first bevel gear can certainly be replaced to be driven using the gearratio identical transmission mechanism of other structures
