The used wind- blocking board 6,12 of the present invention has avoided zone of high pressure, windward side air stream directly to flow to unit inside through the flow direction of guiding rotation zone of high pressure, windward side, connection place air-flow.According to embodiments of the invention, wind-blocking board 6,12 is connected with wind-blocking board yaw device 5,11.The wind-blocking board yaw device can comprise the race ring structure; Shown in Fig. 3 B, 3C; Bearing inner race 5B, the last wind-blocking board 6,12 of fixing of 11B, bearing outer ring 5A, 11A and installation parent parts (for example, air guide sleeve 1 or engine room cover) are fixing; Be provided with for example ball bearing between bearing outer ring and the bearing inner race, can rotate relatively each other.The wind-blocking board yaw device can also comprise motor, and motor can rotate by the driving bearing inner ring, makes bearing inner race rotatable with respect to blade 7 or tower tube 13.Certainly, the invention is not restricted to this, also can be fixedly wind-blocking board of bearing outer ring, and bearing inner race is fixed on to be installed on the parent parts, and the motor driving bearing outer ring rotates.Can be called the bearing fixing circle with being fixed on the race ring of installing on the parent, race ring is called the bearing turning collar in relative rotation.When wind-blocking board when head-on the wind comes from, can farthest seal up the gap of connecting part.
Wind-blocking board yaw device of the present invention is not limited to this race ring structure, for example, can also adopt gear structure, and said gear structure comprises driving wheel and follower, intermeshes through tooth between driving wheel and the follower.The wind sheltering member is installed on the follower.Driving wheel is fixed on to be installed on the parent, and the axle of driving wheel is by motor driving, and driving wheel rotates through the gear driven follower, thereby makes the wind sheltering member rotate.Certainly can also adopt other structures such as chain pitch wheel, all can as long as can realize the mechanical structure that the wind sheltering member can be driven in rotation.
When the wind power generating set proper functioning; Wind-blocking board yaw device 5,11 is not worked; Wind- blocking board 6,12 resets; Be that wind-blocking board 6,12 is returned to initial position to be fixed in this initial position then static with respect to wheel hub 4; The residing position of wind-blocking board when the normal to a surface that so-called initial position is meant the middle position that wind-blocking board is surperficial is substantially parallel with the medial axis direction of wheel hub, in other words, the residing position of wind-blocking board when just the normal of the central position of the horizontal width on wind-blocking board surface is substantially parallel with the medial axis direction of wheel hub.When the generator set proper functioning; The cabin yaw system can make cabin 10 and wheel hub 4 in real time over against head-on the wind comes from (direction and the wind direction of medial axis that is wheel hub 4 is substantially parallel); And wind-blocking board is fixed in initial position and static with respect to wheel hub 4; Over against head-on the wind comes from, wind-blocking board 6,12 naturally also can be thereupon in real time over against head-on the wind comes from real time for wheel hub 4.Wherein, the cabin yaw system is different from the wind-blocking board yaw device, and the cabin yaw system is the common basic facilities that possess of wind-driven generator, and its major function is that it rotated cabin and impeller when yaw system was worked in the cabin, makes impeller aim at the direction of the wind comes from real time.
When thereby extraneous wind speed is lower than the standby of incision wind speed wind power generating set; The cabin yaw system quits work; This moment, the wind-blocking board yaw device 5,11 was started working, control wind-blocking board 6,12 the generator set standby, when the cabin yaw system quits work in real time over against head-on the wind comes from.The flow direction of zone of high pressure, windward side, connection place air-flow is rotated in wind-blocking board yaw device guiding, has avoided zone of high pressure, windward side air stream directly to flow to unit inside, has created precondition for the unit internal environment being effectively controlled when the unit standby.Motor in the wind-blocking board yaw device 5,11 can be supplied power by outside electric power network, also can be by the power supply of accumulation power-supply system, and the accumulation power-supply system can guarantee to rotate wind- blocking board 6,12 proper functioning of connection place when the blower fan off-grid.
Shut down when overhauling when wind power generating set, the cabin yaw system is in the state of quitting work, and this moment, the wind-blocking board yaw device 5,11 can be still in running order, control wind- blocking board 6,12 when generator set is shut down in real time over against head-on the wind comes from.Under outage state, wind power generating set and external electrical network are broken off, and the motor in the wind-blocking board yaw device 5,11 is by the power supply of accumulation power-supply system, and the accumulation power-supply system can guarantee to rotate wind- blocking board 6,12 proper functioning of connection place when the blower fan off-grid.
This shows, when the wind power generating set proper functioning, the work of cabin yaw system, and when wind power generating set standby or shutdown, the work of wind-blocking board yaw device.But the invention is not restricted to this, in another embodiment, wind power generating set proper functioning whether no matter, the wind-blocking board yaw device can be worked always, promptly controls wind-blocking board in real time over against head-on the wind comes from always.
Visible by Fig. 4; Wind-blocking board 6 has approximately surrounded about half of blade 7 circumference (promptly; It is 180 degree that the arc angle of the resulting circular arc of intercepting wind-blocking board cylinder is removed perpendicular to the direction of the axis of root of blade in the edge); But the invention is not restricted to this, wind-blocking board also can surround blade 7 or tower tube 13 circumference 1/3rd to 2/3rds.Even wind-blocking board can surround blade 7 or tower tube 13 circumference 1/4th to 3/4ths, but, if the circumference that surrounds is very few, then sealing effect can variation, wind can carry moisture, sand and dust etc. and get into the gap from the wind-blocking board both sides; Too much even all surround if surround ground, then wind-blocking board facing the wind that part of when being blown to blade 7 or tower tube 13, can receive the resistance of other parts of wind-blocking board, cause and can not stick fully, sealing effect also can variation.
Be a rectangle behind the wind-blocking board cylinder unwrapping of Fig. 4, but the invention is not restricted to this, the top edge of wind-blocking board cylinder not necessarily will be parallel to lower limb; For example can tilt with respect to lower limb; Perhaps top edge can be made up of the line segment of two Different Slope, and top edge also is not necessarily directly, also can be curve or jagged; Or the like, can shelter from the gap as long as can satisfy wind-blocking board.
In addition, wind-blocking board of the present invention is not limited to the structure of this cylinder, and wind-blocking board of the present invention also can be a planar configuration, when wind-blocking board in real time when the wind comes from, the wind-blocking board plane is vertical with the medial axis of wheel hub.But, the wind-blocking board sealing effect of planar configuration is more a little bit poorer slightly than cylinder, and cylinder is an optimal way.
Shown in Fig. 3 B and Fig. 3 C; Wind- blocking board 6,12 is made up of skeleton 6A, 12A and soft material 6B, 12B; But the soft material of wind-blocking board 6,12 is not limited to that kind shown in Fig. 3 B and Fig. 3 C and only is formed on front end according to an embodiment of the invention; The whole extension of wind-blocking board (that is, wind-blocking board except that with part that yaw device 5,11 contacts part) can all constitute by soft material.Soft material can be rubber, metallic thin film, or the like, as long as can being out of shape and being attached to, it treats that contact component (for example, blade 7, tower tube 13) upward gets final product under the condition of being stroked by wind.In another example, whole wind-blocking board (comprising extension and the part that contacts with the wind-blocking board yaw device) can all be made up of soft material, and for example, wind-blocking board all can be made up of titanium alloy material.
Comprise soft material just because of wind-blocking board; Even so touch when treating that contact component and this treat that contact component moves with respect to soft material at soft material; Soft material has wearing and tearing, but because soft material can be out of shape, facings the wind by under the situation of brushing in the soft material front at every turn; Soft material all can tightly touch and treat contact component, so soft material can not weaken owing to the wearing and tearing of soft material the sealing effect in gap.
In addition, because yaw system makes the center of wind-blocking board always in real time over against head-on the wind comes from, so wind-blocking board can farthest block head-on and the wind comes from, and also can farthest be out of shape, thereby guarantees splendid sealing effect.
Wind-blocking board can only be installed in the connecting part of air guide sleeve and blade according to an embodiment of the invention, also can only be installed in the junction of tower tube and engine room cover.
Front end at the wheel hub of wind-driven generator offers a wheel hub circular hole, and this circular hole is used for heat radiation when generator set is worked, and when generator set is shut down, can be used for keeping in repair the nursing staff and overhauls.In the prior art, each blower fan MANUFACTURER does not have particular design at wheel hub circular hole place, is opening-wide state, has brought the hidden danger of accelerated corrosion for the unit internal unit.
According to embodiments of the invention, wheel hub circular hole door 2 (also can be described as sealed door 2) and wheel hub circular hole controlling device for doors 3 (also can be described as sealed door control gear 3) are installed at wheel hub circular hole place.The used wheel hub circular hole controlling device for doors 3 of the present invention can trigger control wheel hub circular hole door 2 automatically and close when unit standby or shutdown, completely cut off the air-flow path of wheel hub and external environment, the function of protection unit internal environment when realizing unit standby, shutdown.When the wind power generating set proper functioning was generated electricity, in order purpose such as to dispel the heat, wheel hub circular hole door 2 can be controlled as open mode.Certainly; If when blower fan is shut down maintenance; If the maintenance man need open wheel hub circular hole door 2 and outside blower fan, overhaul; Wheel hub circular hole door 2 also can be manually opened or be closed, and perhaps also can open or close through the switch that hand triggers on the wheel hub circular hole controlling device for doors 3, safeguards so that carry out blower fan.
