Wind wheel, deceleration device, energy storage device and generator all are that this area is known, and those skilled in the art can adopt suitable known technology according to concrete designing requirement.
Fig. 2 shows a kind of energy storage device that combines the differential gearing function, comprises first semiaxis 31, second semiaxis 33 and housing 37.First semiaxis 31 links to each other with the output 12 of deceleration device 2, is used for the power that receives from wind wheel 1 from deceleration device 2.Second semiaxis 33 is as the part of output revolving shaft 13 or output revolving shaft 13.Output revolving shaft 13 links to each other with the power shaft 14 of generator 5, is used for transmitting power to generator 5.Energy storage device 3 also comprises and first semiaxis 31 is integrally formed first angular wheel 32, and integrally formed second angular wheel 34 of second semiaxis 33, at first, second angular wheel 32, between 34 and simultaneously and a plurality of planetary gears 35 of this two angular wheels engagements and the pinion frame 36 that supports these planetary gears 35.Wherein, housing 37 surrounds above-mentioned member and integrally formed with pinion frame 36.Wherein, housing 37 has constituted a reel, the long rope 62 that can for example form with steel wire rope or any other suitable material, and the one of which end is fixed on the housing 37, and the other end is fixed on the weight 61.When long rope 62 was wrapped on housing 37 outer surfaces along with the rotation of housing 37, weight 61 was raised, thereby the kinetic energy of housing 37 is converted into the potential energy of weight 61.Certainly, it will be understood by those skilled in the art that weight 61 can also be suspended on the housing through various forms of assembly pulleys.Assembly pulley can be fixed on the pylon of wind power plant, perhaps, is fixed on the for example portal frame of other installing.The quality of weight and the length of long rope can be carried out concrete design according to the concrete designing requirement and the situation of local wind field.As substitute mode, housing 37 can drive various forms of energy storage members such as flywheel, torque spring or air compressor, it will also be appreciated that being used for driving water pumper carries out retaining.The structure that this energy storage and differential gearing are combined as a whole was authorized in No. the 200920179109.0th, the Chinese utility model patent of Gao Zehang on August 4th, 2010, described in detail.This part related content in the document comprises in this application by reference.
Art technology is appreciated that; Also can omit the above-mentioned structure relevant with differential gearing; And traditional energy-storage function structures such as weight, flywheel, torsion spring, air compressor and water pump are combined with the output 12 of deceleration device 2, thereby stable rotating speed output is provided at output 12 places.
Require needed constant rotational speed for input rotating shaft 14 places at generator 5 obtain to mate exactly municipal electrical network networking, the present invention is provided with a kind of mechanical type revolution speed control device 4 between generator 5 and energy storage device 3.
Fig. 3 shows the mechanical type revolution speed control device 4 according to one embodiment of the present invention.Mechanical type revolution speed control device 4 comprises worm gear 42 and worm screw 41.Worm screw 41 can link to each other with a motor (not shown), under the driving of motor, with predetermined rotational speed, is first revolving member of the present invention.Worm gear 42 and worm screw 41 engagements, and can be fixed in the input rotating shaft 14 of generator, input rotating shaft 14 links to each other with the output revolving shaft 13 of energy storage device 3, receives the rotating speed after stablizing, and is second revolving member of the present invention.
Gearratio between the specific requirement that is connected to the grid according to plan and two revolving members, worm screw 41 can have different desired speeds under the driving of motor.
In execution mode shown in Figure 3, worm gear 42 combines through key 43 and generator power shaft 14.In other embodiments, worm gear 42 can be one with generator power shaft 14.
According to another embodiment of the present invention, worm and gear can substitute with the gear of pair of meshing.According to another execution mode of the present invention, second revolving member (worm gear or gear) can be fixed on the output revolving shaft 13 of energy storage device 3.Therefore, in the present invention, second revolving member links to each other with the input rotating shaft of generator, comprises in the input rotating shaft that is fixed to generator directly or indirectly.
Below, in conjunction with accompanying drawing 1-3 the course of work of the present invention is described.In wind field; When wind-force reaches intended level; The gentle breeze of 3 meters of per seconds for example, wind wheel 1 begins to rotate, and the rotation of wind wheel rotating shaft 11 passes to first semiaxis 31 of energy storage device 3 through the output 12 of deceleration device 2; First semiaxis 31 drives the first integrally formed with it angular wheel 32 and rotates, and the rotating speed after second semiaxis 33 will be stablized is passed to the input rotating shaft 14 of generator 5 then.
When the rotating speed coupling (promptly meeting worm gear transmission ratio) behind the desired speed of worm screw 41 and energy storage device 3 inputs stable, worm screw 41 is close to idle running.
When the rotating speed behind the rotating ratio energy storage device of the pairing worm gear 42 of the desired speed of worm screw 41 3 inputs stable was big, the output revolving shaft 13 resulting unnecessary kinetic energy of energy storage device 3 passed to energy storage device 3, were absorbed by wherein energy storage member.
Rotating speed behind the rotating ratio energy storage device of the pairing worm gear 42 of the desired speed of worm screw 41 3 inputs stable hour; Worm and gear produces braking force to the output revolving shaft 13 of energy storage device 3; This braking force causes energy storage device 3 to pass to energy storage device 3 at the unnecessary kinetic energy that input (the perhaps output of deceleration device 2) place obtains, by energy storage member absorption wherein.
With the energy storage device with differential function shown in Figure 23 is example.No matter be the torque increase on first semiaxis 31 (input) or second semiaxis 33 (output), planetary gear 35 is revolved round the sun, weight 61 is raised, and realizes energy storage.The energy storage member that acts on the output 12 of deceleration device 2 directly absorbs the excess energy from revolution speed control device 14 and deceleration device 2.
As stated, through between energy storage device and generator, being provided with according to mechanical type revolution speed control device of the present invention, the input rotating shaft of generator can obtain to incorporate into required accurate rotating speed.And mechanical type revolution speed control device according to the present invention is made up of revolving members such as worm and gear or gears, with present use be used for realize that the power electronic equipment of constant-speed and constant-frequency compares, its cost is much little.
With reference to accompanying drawing the present invention has been carried out concrete description above.But, it should be appreciated by those skilled in the art that top specific descriptions only are given by way of example, be used for illustrative purpose, be not to be to be used for limiting protection scope of the present invention.Have benefited from instruction of the present invention; Those skilled in the art can make various modification, revise or replacement above-mentioned specifically described execution mode as the case may be under the situation that does not exceed protection range of the present invention, and these modification, modification or replacement fall into protection scope of the present invention.
