Piece becomes oar stopping means and the wind power generating set using the vane propeller-changing stopping means.
Background technology
With the development of society, the energy and environment increasingly become the two large problems of face of mankind nowadays, wind energy is used as one
The regenerative resource for planting cleaning is increasingly valued by people, and its topmost purposes is the power resources as generating.Wind
Power generator can be divided mainly into two classes：Horizontal axis wind-driven generator and vertical axis aerogenerator.Using water more in general the power station
Flat axis wind power generator, in power generation process, because wind-force size is continually changing, it is therefore desirable to by wind-driven generator
The blade of group is adjusted, so that the rotating speed of the blade of wind power generating set keeps constant, it is ensured that the stabilization of power generation process, its
In, limit switch plays very important effect in oar and the security control generated electricity is become.
Pitch-controlled system controls the rotating speed for the wind wheel for rotating and rotating by blade by controlling the angle of blade, and then controls
The power output of wind power generating set processed, and wind power generating set safe stopping can be made by way of aerodynamic braking
Machine.The blade (specifically, the root of blade) of wind power generating set is connected by pitch variable bearings with wheel hub, and each blade has
The pitch drive system of its relatively independent electric control synchronous.In wind power generating set during normal operation, when wind speed exceedes wind-force

Increase the frictional force between the inner surface 23a of roller 12 and first and the second inner surface 23b during position, and then strengthen limit switch 10
Triggering effect.
Below with reference to Fig. 3 to Figure 10 descriptions according to the vane propeller-changing stopping means of one embodiment of the present utility model
Trigger assembly 20 realizes spacing operation in first position, the second place and the 3rd location triggered limit switch.
As shown in Figure 3 and Figure 4, when the distance between limit switch 10 and trigger assembly 20 meet roller 12 accessible first
When triggering surface 21a (first position), as trigger assembly 20 rotates together with pitch variable bearings 30, the frizzen of limit switch 10
11 enter through slot 21, and the contact of roller 12 first triggers surface 21a, drive and touch with the first triggering surface 21a rollers 12 contacted
Hair bar 11 is subjected to displacement or angle change, and then triggers the construction of switch inside limit switch 10, so that pitch motor 50 is no longer
Operation, so that pitch variable bearings 30 stop the rotation.
As shown in Figure 5 and Figure 6, when the distance between limit switch 10 and trigger assembly 20 meet the accessible triggering of roller 12
During second triggering surface 22 (second place) of component 20, as trigger assembly 20 rotates together with pitch variable bearings 30, with triggering
The roller 12 that second triggering surface 22 of component 20 is contacted drives frizzen 11 to be subjected to displacement or angle change, and then triggers spacing
Construction of switch inside switch 10, so that pitch motor 50 is not reruned, so that pitch variable bearings 30 stop the rotation.
It is as described above to trigger the lateral contraction type bar linkage structure that is particularly suitable for use in first position triggering and the second place
Limit switch.
As shown in Figure 7 to 10, when the distance between limit switch 10 and trigger assembly 20 meet roller 12 accessible the
During three triggering surface 23 (the 3rd positions), as trigger assembly 20 rotates together with pitch variable bearings 30, the triggering of limit switch 10
Bar 11 enters through slot 21, and the contact of roller 12 the 3rd triggers surface 23, is contacted with the 3rd triggering surface 23 of trigger assembly 20
Roller 12 drives frizzen 11 to be subjected to displacement or angle change, and then triggers the construction of switch inside limit switch 10, so as to become
Pitch driver does not rerun, so that pitch variable bearings stop the rotation.
Fig. 7 to Figure 10 triggering mode is particularly suitable for use in the limit switch of axial expansion type bar linkage structure.Specifically, when
When the position on three triggering surfaces 23 turns to position 232 from position 231, due to the pressure between the 3rd triggering surface 23 and roller 12
Power can become big so that frictional force increases, and due to being formed with pattern structure 23c on the 3rd triggering surface 23, therefore spacing open
Closing 10 frizzen 11 can be moved with the rotation of trigger assembly 20, so as to trigger limit switch 10.
Above though it is shown that according to the concrete structure of the vane propeller-changing stopping means of embodiment of the present utility model, but leaf
The concrete structure that piece becomes oar stopping means is not limited to this.Figure 11 is to show the blade according to another embodiment of the present utility model
Become the structural representation of oar stopping means.
Reference picture 11 is different according to the trigger assembly 20 of the vane propeller-changing stopping means of another embodiment of the present utility model

Outside, according to the other structures of the vane propeller-changing stopping means of another embodiment of the present utility model with according to of the present utility model
The structure of the vane propeller-changing stopping means of one embodiment is identical, therefore for sake of simplicity, will omit repetitive description.
Specifically, in the present embodiment, the first triggering surface 21a can be inclined surface, and the first triggering surface 21a inclines
Tiltedly to cause direction of rotation of the thickness along pitch variable bearings 30 of bottom panel from the upstream side of trigger assembly 20 to downstream gradually
Increase, to be easier to trigger limit switch 10.First triggering surface 21a inclined degree can be designed according to applicable cases.
When the first triggering surface 21a inclined degree is larger, between the first triggering surface 21a and the 3rd triggering surface 23
Minimum range d3 may be less than roller 12 diameter, in this case, passing through roller 12 and first triggering surface 21a
When being in contact and triggering limit switch 10, roller 12 is limited by space can be stuck in the first triggering surface 21a and the 3rd triggering table
Between face 23.Therefore, as shown in figure 11, trigger assembly 20 may also include extension 24, the extension 24 is along pitch axis
Hold 30 direction of rotation from the upstream side of bottom panel towards downstream and bottom panel it is coplanar extend.As shown in figure 11, extension
Points 24 upper surface triggers that surface 21a is coplanar with first, and the lower surface of extension 24 and the outer surface of bottom panel are coplanar.That is,
The extension 24 of bottom panel is formed as the form of no top panel covering.
Figure 13 is the structural representation for showing the vane propeller-changing stopping means according to another embodiment of the present utility model.
It is different from according to the trigger assembly 20 ' of the vane propeller-changing stopping means of another embodiment of the present utility model according to this
The trigger assembly 20 of the vane propeller-changing stopping means of utility model one embodiment.According to the spacing dress of the vane propeller-changing of the present embodiment
The trigger assembly 20 ' put is formed as step shape, and the first triggering surface can be first step side surface 21 ', the second triggering
