Abstract
The invention relates to an automatic cable unwinding system of a wind generating set. The automatic cable unwinding system is arranged in a tower below the wind generating set (1) and comprises a controller, a wire spool (3), a pulley (4), a reinforcing steel bar rope (5), a heavy hammer (6) and a position switch (7), wherein the wire spool (3) is connected with the wind generating set (1) and rotates along with a machine head of the wind generating set (1), one end of the reinforcing steel bar rope (5) is fixed on the wire spool (3), the other end of the reinforcing steel bar rope (5) penetrates through the pulley (4) and is fixed on the heavy hammer (6), the pulley (4), a guide rail (8) and the position switch (7) are directly and indirectly arranged on the side wall in the tower. Compared with the prior art, the automatic cable unwinding system has the advantages that whether a cable unwinding signal is given according to a trigger signal of the position switch (7) so as to control a yaw motor (2), thus an automatic cable unwinding function of a fan is achieved, and the problem that a cable (9) is damaged due to excessive cable twisting is avoided.
Description
Technical field
The present invention relates to the wind power generating set of active yawing, especially relate to a kind of wind power generating set automatic cable-releasing system.
Background technique
For improving the efficiency of wind power generating set, wind power generating set generally has driftage function windward, but cable causes pylon from motor, one end fixedly the other end with head rotating, will inevitably there is the phenomenon that cable reverses, surpass the tolerance range of cable, will inevitably damage cable.Along with the extensive use of Power Electronic Technique in wind-powered electricity generation industry, increasing wind power generating set adopts the form of active yawing.If selection collector ring, is not that cost is very high, is exactly the requirement that does not meet signaling line.The present invention solves the problem of untying the mooring rope of this generator set just, and cost is lower.
Summary of the invention
Object of the present invention is exactly a kind of wind power generating set automatic cable-releasing system of practical that provides in order to overcome the defect of above-mentioned prior art existence, the cable that can make wind power generating set reverse because of driftage returns to previous condition, avoids cable because reversing the problem that excessively causes damage.
Object of the present invention can be achieved through the following technical solutions:
A kind of wind power generating set automatic cable-releasing system, be arranged in the tower cylinder of wind power generating set below, automatic cable-releasing system comprises controller, wire spool, pulley, reinforcing bar rope, weight and position switch, described wire spool via controller and wind power generating set are connected and rotate with the head of wind power generating set, described reinforcing bar rope one end is fixed on wire spool, the other end is fixed on weight through pulley, and described pulley, guide rail and position switch directly or are indirectly arranged on the sidewall in tower cylinder.
Described weight is set in guide rail and along guide rail and moves up and down, and starts corresponding position switch to relevant position.
Described position switch is provided with 5, is connected in turn on guide rail from top to bottom.
Distance between second place switch and the 4th position switch and the ratio of wire spool diameter are the number of turns that reinforcing bar rope can be wound around on wire spool, and this number of turns should be less than the twice that cable can bear the number of turns of torsion.
Described controller is with automatic cable-releasing module, and controller is accepted the signal that position switch transmits, and controls yaw motor and moves accordingly.
Described wind power generating set associated components comprises blade, wheel hub, motor, cabin, tower cylinder, yaw motor etc.
Compared with prior art, the present invention has effectively solved the problem of untying the mooring rope, and the cable that can make wind power generating set reverse because of driftage returns to previous condition, thereby has avoided cable to damage because of torsion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of position switch.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
A kind of wind power generating set automatic cable-releasing system, its structure as shown in Figure 1, be arranged in the tower cylinder of wind power generating set 1 below, automatic cable-releasing system comprises controller, wire spool 3, pulley 4, reinforcing bar rope 5, weight 6 and position switch 7, wire spool 3 via controllers and wind power generating set 1 is connected and rotates with the head of wind power generating set 1, one end of reinforcing bar rope 5 is fixed on wire spool 3, the other end is fixed on weight 6 through pulley 4, and pulley 4, guide rail 8 and position switch 7 directly or are indirectly arranged on the sidewall in tower cylinder.
Wherein, weight 6 is set in guide rail 8 and along guide rail 8 and moves up and down, to relevant position, can start corresponding position switch 7, position switch 7 is provided with 5, as shown in Figure 2, comprise primary importance switch 71, second place switch 72, three position switch 73, the 4th position switch 74 and the 5th position switch 75 being connected in turn on guide rail 8 from top to bottom.Controller is with automatic cable-releasing module, and controller is accepted the signal that position switch 7 transmits, and controls yaw motor and moves accordingly.
Distance between second place switch 72 and the 4th position switch 74 and the ratio of wire spool 3 diameters are the number of turns that reinforcing bar rope 5 is wound around on wire spool 3, and this number of turns is less than the twice that cable can bear the number of turns of torsion.That is to say, second place switch 72 and the 4th position switch 74 be the corresponding limit of manually just going off course and reversing during anti-driftage respectively.The associated components of wind power generating set 1 comprises blade, wheel hub, motor, cabin, tower cylinder, yaw motor etc.Blower fan triggers this two position switchs while normally moving, controller sends the signal that unties the mooring rope, and yaw motor 2 actions stop when weight 6 triggers second place switch 72 or the 4th position switch 74.Debugging blower fan triggers this two position switchs while manually going off course, controller limits can only be toward the direction driftage of three position switch 73, and past limit direction is partially invalid.Primary importance switch 71 and the 5th position switch 75 are double protective nature, and function is the same with the 4th position switch 74 with second place switch 72, thereby can prevent that cable 9 from excessively causing damage because turning round cable.
