Extensive concern of the wind-power electricity generation due to having caused people the advantages of its own, makes wind generating technology in energy shortage Today have great researching value.But the wind of nature is all changing all the time, this randomness of wind and unstable Property just to wind energy utilization bring many problems.If wind-driven generator is without active protective device, when more than wind-driven generator System can occur that high wind wipes out blade, generator speed is too fast and burns, the tail vane that fractures, freely folds tail after tolerance range It is unable to complete protection act, small-sized wind power generator in rudder actual motion, it is not high to be folded mechanically tail vane installation space deficiency intensity Etc. a series of failure problems.
Summary of the invention
The present invention is easy to burn, fracture tail vane for the problem that disadvantage mentioned above based on existing wind-power electricity generation is solved.It proposes A kind of wind-driven generator actively folds tail vane and its hydraulic control system, and wind-driven generator is in extreme environment operating voltage or electricity It is more than specified online for flowing, and brake actuating mechanism just will start, and control system detects energy storage battery condition such as after the completion of brake Electricity not enough will releasing of brake after 30 minutes, continuously brake repeatedly for three times, system, which will will start, folds the wind sheltering of tail vane mechanism Protect wind-driven generator.
The specific technical solution of the present invention is as follows:
Wind-driven generator actively folds tail vane, including pedestal, and revolving body is mounted on the base, and pacifies on the revolving body Equipped with chassis, which is characterized in that be equipped with generator on the chassis, the rear on chassis is equipped with steering tail vane, the power generation Machine rear is equipped with the brake of control generator itself and control turns to the hydraulic control system that tail vane turns to protection;
The hydraulic control system includes hydraulic pump, reversal valve, overflow valve, turns to protection executing agency and brake execution machine Structure;Overflow valve formation level pressure overflow oil circuit in parallel with hydraulic pump and fuel tank;The corresponding oil of steering protection executing agency Road is sequentially connected bidirectional throttling valve, reversal valve, and the pressure oil circuit and oil return opening of the reversal valve are connect with hydraulic pump respectively, described Hydraulic pump connects fuel tank and hydraulic pump motor;
The corresponding oil circuit of the brake actuating mechanism is sequentially connected two-way valve, check valve, hydraulic pump and fuel tank and forms oil inlet Oil circuit;The corresponding oil circuit of the brake actuating mechanism is sequentially connected two-way valve, type pilot check valve and fuel tank and forms oil return circuit.
Beneficial effects of the present invention: wind-driven generator is more than specified online, brake in extreme environment operating voltage or electric current Executing agency just will start, and control system detection energy storage battery condition such as electricity not enough will be at 30 minutes after the completion of brake Releasing of brake afterwards continuously brakes repeatedly for three times, and system, which will will start, folds tail vane mechanism wind sheltering protection wind-driven generator.A whole set of machine Structure is at low cost, operational safety, reliable performance, has a very important significance to the service life for extending wind-driven generator, and be Middle-size and small-size wind-driven generator actively protects release mechanism to provide Research foundation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that wind-driven generator of the present invention actively folds tail vane;
Fig. 2 is present hydraulic system control figure.
Specific embodiment
