Embodiment
Shown in Fig. 1-4, turn round cable protection apparatus structure schematic representation for wind driven generator yaw of the present invention, it comprises: with a plurality of flip flop equipments of driftage gear ring rotation; A plurality of mechanical contacts corresponding to a plurality of flip flop equipments; Wherein, a plurality of mechanical contacts comprise untie the mooring rope contact and limit contact, and with respect to limit contact, the contact of untying the mooring rope is triggered by pairing flip flop equipment earlier.
Concrete, like Fig. 1, shown in 2, wind driven generator yaw is turned round the cable protection device and is comprised with five flip flop equipments 6,7,8,9,10 of driftage gear ring rotation and five mechanical contacts 1,2,3,4,5 corresponding respectively with five flip flop equipments.Wherein, five flip flop equipments are arranged successively and are integrally formed through affixed mode along same axis X, and five flip flop equipments be in same horizontal plane five planes respectively around axis X along the formed quadrant of different direction different rotation angle.In five flip flop equipments; The first, the 4th and the 5th flip flop equipment 6,9,10 forms along clockwise direction rotation shown in Figure 1 around axis X for respective planes, and second, third flip flop equipment 7,8 forms along counter clockwise direction rotation shown in Figure 1 around axis X for respective planes.In addition, a plurality of flip flop equipments can also be processed through integral body processing through a single piece.
Wherein, As shown in Figure 1; Be followed successively by with above-mentioned five corresponding mechanical contacts of flip flop equipment of arranging successively along axis X: reset and direction show contact 1, limit on the left contact 2, left side contact 3, limit on the right-right-hand limit contact 4 and the right side contact 5 of untying the mooring rope of untying the mooring rope; And the central angle of three, five flip flop equipment corresponding with the left and right contact of untying the mooring rope greater than with the central angle of respectively corresponding the second, the 4th flip flop equipment in left and right limit contact, and the central angle of first flip flop equipment 6 is 180 °.Therefore when five flip flop equipments with the driftage gear ring during along counter clockwise direction driftage shown in Figure 2, the 3rd flip flop equipment 8 backs down contact 3 of untying the mooring rope, a left side corresponding with it earlier, so yaw system needs go off course to untie the mooring rope to clockwise direction shown in Figure 2; If this moment, yaw system continued along driftage counterclockwise; This moment, second flip flop equipment 7 can back down limit on the left pairing with it contact 2; This moment, the wind-powered electricity generation unit was shut down by protection because of triggering this limit on the left contact, and behind the compressor emergency shutdown, must just can resume work behind the human intervention.Equally, when five flip flop equipments with the driftage gear ring during along clockwise direction shown in Figure 2 driftage, the 5th flip flop equipment 10 backs down contact 5 of untying the mooring rope, the right side corresponding with it earlier, so yaw system needs to counter clockwise direction driftage shown in Figure 2 to untie the mooring rope; If this moment, yaw system continued driftage along clockwise direction; This moment, the 4th flip flop equipment 9 can back down limit on the right-right-hand limit pairing with it contact 4; This moment, the wind-powered electricity generation unit was shut down by protection because of triggering this limit on the right-right-hand limit contact, and behind the compressor emergency shutdown, must just can resume work behind the human intervention.
By above-mentioned visible; The left and right cable protection of separating of yaw system is before left and right limit protection; Therefore no matter yaw system is along still driftage counterclockwise clockwise shown in Figure 2; The capital was triggered earlier before triggering limit protection and is separated cable protection, therefore strong increase the stability of system, and can also effectively turn round the cable limit and protect cable.
Wherein, First flip flop equipment 6 is corresponding with reset and direction demonstration contact 1 in five mechanical contacts; When cable was in complete plumbness, reset and direction showed that contact 1 is triggered by first flip flop equipment 6 or disengaging just triggers, and this moment, yaw system was neither turned round cable to counter clockwise direction shown in Figure 2; Do not turn round cable yet, therefore go off course and turn round cable reset through rising edge or trailing edge to clockwise direction; If cable is turned round cable to counter clockwise direction shown in Figure 2 or clockwise direction; Then go off course and turn round the demonstration of cable direction, as turning round cable, referring to Fig. 1 to counter clockwise direction through high level or low level; Because said flip flop equipment 6 is semicircular cylinder; This moment, this reset and direction showed that the contact 1 and first flip flop equipment 6 still keep in touch, and kept high level state, then went off course to turn round the cable direction and be shown as left drift and turn round cable; And when clockwise direction is turned round cable,, will be in low level state because said flip flop equipment 6 shows that with said reset and direction contact 1 disengages, then display direction is that the right avertence boat is turned round cable.
Preferably, five affixed becoming one of flip flop equipment, promptly five protection node flip flop equipments are solidified togather yaw system are protected, and when regulating the yaw system protection, all five flip flop equipments are interlock adjusting together all at every turn.Therefore increased the stability of system, having improved goes off course turns round the protective value of cable, has also improved debugging, maintenance efficiency simultaneously, has reduced the requirement to the staff, has reduced cost of equipment maintenance.
The present invention also provides a kind of wind driven generator yaw to turn round the cable protection method, and it comprises the steps:
1) five flip flop equipments and five corresponding mechanical contacts are set, so that each flip flop equipment in five flip flop equipments triggers mechanical contact corresponding in five mechanical contacts during with the rotation of driftage gear ring;
2) untie the mooring rope contact and the limit contact in five mechanical contacts is set to when the driftage of cable system is turned round in driftage, and the contact of untying the mooring rope is positioned at the position that is triggered earlier, the position that is triggered after limit contact is positioned at;
3) after the contact of untying the mooring rope is triggered by the flip flop equipment of correspondence, make driftage turn round the operation of untying the mooring rope of going off course of cable system;
4) after limit contact is triggered by the flip flop equipment of correspondence, make the wind-powered electricity generation unit protected shutdown.
Wherein, the contact of untying the mooring rope comprises contact and the right side contact of untying the mooring rope of untying the mooring rope, a left side, and limit contact comprises limit on the left contact and limit on the right-right-hand limit contact.
Wherein, also comprise reset in five mechanical contacts and turn round the cable direction showing the contact, and after being triggered by corresponding flip flop equipment can the go off course reset of turning round cable and the demonstration of cable direction of twist.
Preferably, reset shows that with direction the contact is corresponding with the same flip flop equipment in five flip flop equipments.Like this, only five nodes need be set can carry out corresponding protection to the wind-powered electricity generation unit, thereby has reduced the error of manual operation, and has reduced the maintenance workload and the maintenance cost in later stage.
Although preceding text have been done detailed description to the present invention; But the invention is not restricted to this; The technician in present technique field can principle according to the present invention make amendment, and therefore, all various modifications of carrying out according to principle of the present invention all are to be understood that to falling into protection scope of the present invention.
