Abstract
The invention discloses a self-adaptive locking hydraulic coupler for a transmission chain of a wind turbine generator, and belongs to the technical field of wind power generation. The device comprises an electromagnetic valve, a guide wheel, a turbine, a pump wheel, a signal monitoring controller, an input shaft, a locking piston, a damping assembly and a sensor. The sensor monitors equipment vibration and temperature parameters in real time and transmits the parameters to the signal monitoring controller through a cable. The signal monitoring controller controls the displacement direction of the electromagnetic valve according to monitoring data, so that the joint state of the locking piston is adjusted, and self-adaptive switching between rigid transmission and flexible transmission is achieved; the hydraulic coupler alarm assembly receives an alarm signal of the signal monitoring controller through a cable, and real-time reporting of a fault is achieved. According to the device, the design that a low-viscosity synthetic oil medium is matched with a light-weight corrosion-resistant material shell is adopted, hydraulic transmission loss and impact damage are effectively reduced, and the service life is remarkably prolonged.
