Background technique
In the prior art; there is many hidden danger in the safety control of middle-size and small-size wind-driven generator; the following aspect of main embodiment: (1) can not realize the reliable shutdown under the strong wind operating mode; existing arrestment mechanism mostly is drum-type or the disk type braker that is installed on the wind-driven generator lower velocity shaft; because braking moment is limited; can not be implemented in the safety brake under the strong wind operating mode, only can be used as a kind of locking device of shutting down maintenance.(2) life-span weak point because braking moment is limited, is shut down under the strong wind operating mode and is caused brake shoe friction material serious wear, changes frequent.(3) reliability is low, owing to can not realize the reliable shutdown under the strong wind operating mode, causes the wind wheel hypervelocity again and again, the phenomenon of burn-down of electric motor.(4) automaticity is low, and existing braking system to be adopted manually, can't realize the automatic startup-shutdown control of wind-driven generator.
Summary of the invention
The utility model has overcome the deficiencies in the prior art; middle-size and small-size wind-driven generator automatic safety control system has been proposed; this system provide a kind of safe and reliable, automaticity is high can make the system that wind-driven generator can safe and reliable operation when wind speed 10-30m/s wide variation, this system can monitor unit runnability in real time, realize stoppage protection and start operation automatically.
The technical solution of the utility model is: middle-size and small-size wind-driven generator automatic safety control system, be made up of three subsystems: feather manipulation and arrestment mechanism, braking state detect actuator, automatic detection and control system.
Feather described in the utility model is handled with arrestment mechanism and is made up of the lazy-tongs that are installed in the wind wheel front end, the change oar guide rod that runs through motor shaft, gear mechanism, brake connecting rod, the break in the cabin, gear mechanism in the cabin rotates drive change oar guide rod traction feather lazy-tongs the blade angle is placed negative value, gear mechanism is after the feather operating mechanism puts in place, drive the brake arm rotating cam and start brake, and braking brake does not start in the process that becomes the oar manipulation.
Braking state described in the utility model detects with actuator to be made up of electric capstan, electric capstan support, pulley, slide block, brake wire, brake spring, position transducer, brake wire one end links to each other with the gear arm of feather operating mechanism, the other end links to each other with electric winch by pulley, the slide block of pulley both sides is the compression brake spring when pulley moves, and initial and the braking place of putting in place are provided with position limit switch in braking.
Automatic detection and control system described in the utility model is made up of controller, anemoscope, position limit switch signal, generator voltage sensor, net electric transducer.It is characterized in that controller testing environment wind velocity signal, generator voltage signal, net electrical signal, position limit switch signal etc., and start electric winch execution wind-driven generator shutdown and start action according to the input situation.
The utlity model has following beneficial effect:
1, to can be implemented in wind speed can be that negative value makes the wind wheel deliberate speed loss lose acceleration power with the blade tip angular adjustment by the gear mechanism in the cabin when excessive in the setting of feather operating mechanism, and produce the reverse aerodynamical resistance distance of impelling wind wheel to stop.
2, the interlock of feather operating mechanism and brake structure is provided with and has realized in the too high elder generation of wind speed wind wheel stall braking then to remove the power of wind wheel, has reduced the wearing and tearing of brake friction material, improves the life-span of break.
3, braking force detect can control brake power with being provided with of actuator size avoid in the braking process the excessive brake wear that causes of braking force serious, the problem of electric winch overload improves the reliability of system.
4, automatic detection and control system the running state that can detect the wind-driven generator unit in real time is set, and can be too high at wind speed, carry out stoppage protection timely under the improper operating mode such as equipment failure, electric network fault; When the condition situation meets the demands, start wind-driven generator automatically, can realize automatic control, unattended function.
5, the power autonomous setting of automatic safety control system can improve the reliability of unit so that system does not rely on the startup shutdown that external condition is controlled wind-driven generator automatically.
