Fig. 2 is the structural representation of the utility model embodiment two wind generating unit.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
Embodiment one
With reference to figure 1, be cylinder type gravity voltage stabilizer described in the utility model, it comprises an oil cylinder main body 40, comprise flow of liquid inlet D and liquid flowing outlet C on this oil cylinder main body 40, one side of this oil cylinder main body 40 has a stealthy hole A, and (among Fig. 1 because stealthy hole is difficult for indicating, so it is clear in order to indicate, stealthy hole A adopts two short-terms to indicate), also comprise a gravity stable-pressure device (figure does not show) in this oil cylinder main body 40, this gravity stable-pressure device is used for making the liquid that enters this cylinder type gravity voltage stabilizer to produce the stable output of constant current.In the present embodiment, gravity stable-pressure device in this oil cylinder main body 40 comprises a piston 41, one end of this piston 41 connects a hanger G, has a check valve opening B on this piston 41, and this piston 41 also has the elastic device 42 that this check valve opening of control B opens and closes.Below, with oil is example, introduce the working principle of this cylinder type gravity voltage stabilizer, it makes piston 41 produce certain pressure based on hanger G and makes the stable output of oil pressure, when oil hydraulic pump oil (being the piston bottom in the present embodiment) when flow of liquid inlet D is pressed into the cylinder type gravity voltage stabilizer 4, under the pressure effect that is pressed into oil,, when piston 41 is higher than stealthy hole A, under the effect of piston pressure, oil is extruded from stealthy hole A piston 41 jack-up.If the oil pressure that enters in the cylinder type gravity voltage stabilizer 4 is very high, oil pressure pushes up piston 41 to the top of gravity voltage stabilizer 4, this moment, the spring 42 on piston 41 was compressed, make check valve opening B open, at this moment higher oil pressure makes oil also flow out by this liquid flowing outlet C by the space that check valve opening B flows into piston top from the space of piston bottom, and make the oil that remains some in piston 41 lower space, and piston 41 and hanger G are constant to the pressure of the oil in piston 41 lower space, thereby the oil pressure of the oil that flows out from stealthy hole A also remains at a constant value, thereby realizes the output of constant flow rate constant pressure.After the oil pressure of the oil that flow of liquid inlet D flows into reduced, hanger G drove piston 41 and descends, and stealthy hole A is blocked.In the present embodiment be the medium explanation, also can adopt other media well known to those skilled in the art with oil.More specifically working principle two elaborates in conjunction with the embodiments.
Embodiment two
With reference to figure 2, wind generating unit comprises a windmill 1, one oil hydraulic pump 2 that is connected with this windmill 1 and a liquid tank 3 that is connected with this oil hydraulic pump 2, one oil hydraulic motor 6 that links to each other with this liquid tank 3 and one and these oil hydraulic motor 6 generator coupled 7, this wind generating unit also comprises: a cylinder type gravity voltage stabilizer 4 that links to each other with this liquid tank 3 with this oil hydraulic pump 2 respectively, wherein, this oil hydraulic pump 2 is connected to the flow of liquid inlet of this cylinder type gravity voltage stabilizer 4, the liquid flowing outlet of this cylinder type gravity voltage stabilizer 4 is connected to this liquid tank 3, the stealthy hole A of this cylinder type gravity voltage stabilizer 4 is connected to this oil hydraulic motor 6, wherein, be connected by a flow control valve 5 between this liquid tank 3 and this oil hydraulic motor 6.The working principle of this wind generating unit is as follows: when the natural wind greater than rated wind speed blows windmill 1, windmill 1 drives the liquid (extracting liquid in the liquid tank shown in arrow a1 direction among Fig. 2) in the oil hydraulic pump 2 extraction liquid tanks 3, liquid is pressed into cylinder type gravity voltage stabilizer 4 along the a2 direction through oil hydraulic pump 2, after liquid enters cylinder type gravity voltage stabilizer 4, liquid is under the effect of pressure, the piston that hangs with constant weight hanger G in the cylinder type gravity voltage stabilizer 4 is risen, thereby open stealthy hole A, liquid enters oil hydraulic motor 6 along arrow b1 direction through stealthy hole A, the pressure of liquid and flow are under 4 effects of cylinder type gravity voltage stabilizer at this moment, liquid is with constant voltage, the constant current amount drives oil hydraulic motor 6 and drives generator 7 generatings, and the flow of liquid of oil hydraulic motor 6 outlets flows back to liquid tank 3 along arrow c1 direction through flow control valve 5.When wind speed during less than rated wind speed, the fluid pressure that can make oil hydraulic pump 2 be pressed into cylinder type gravity voltage stabilizer 4 reduces, thereby unablely opens stealthy hole A, windmill 1 stall this moment, generator 7 generation outages.When natural wind speed during greater than rated wind speed, the hydraulic pressure that oil hydraulic pump 2 produces is bigger, the liquid that this hydraulic pressure is bigger constantly is pressed in this cylinder type gravity voltage stabilizer 4, cause the piston that hangs with hanger G to rise always, when piston rises to the top of this cylinder type gravity voltage stabilizer 4, the elastic device that is provided with on the piston is compressed so that check valve opening B is opened, liquid flows back into liquid-storage container 3 along the b2 direction through check valve opening B, at this moment, because the liquid capacity in this cylinder type gravity voltage stabilizer 4 in the piston lower space is constant, and liquid pressure under the pressure effect of piston and hanger G also is constant, so the liquid that is forced out from stealthy hole A is constant current amount constant voltage liquid, oil hydraulic motor 6 still can drive generator 7 generatings with stabilized speed like this, no matter how extraneous wind speed changes thus, in case it surpass to drive the required minimum wind speed (being rated wind speed) of generator 7, this wind generating unit is not stably generated electricity by the influence of wind speed variation just can.
Though more than described embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is limited by appended claims.Those skilled in the art can make numerous variations or modification to these mode of executions under the prerequisite that does not deviate from principle of the present utility model and essence, but these changes and modification all fall into protection domain of the present utility model.
