Wind power generation braking system

Abstract

The present invention provides a braking device of a wind generator including a lever and an actuator and is characterized in that the actuator can drive the lever; the lever can rotate within the plane which is parallel to a brake shoe; a transmission mechanism drives the brake shoe; the transmission mechanism can transform the rotation into the transverse axial motion to provide enough driving power; the actuator is adopted to drive the lever, the lever effect and the transmission effect can increase the actuating force obviously. The present invention is applied to a wind generating device and the driving performance of the present invention is 23 percents higher than the traditional wind generator.

Description

technical field [0001] The invention relates to an actuating device, in particular to a braking device for a wind power generator. Background technique [0002] Brakes for rotors of wind power generation equipment or similar large-scale equipment must be able to generate a strong braking force, so a sufficiently strong actuator is required. So far, a hydraulic actuator has been used, which directly Creates the engagement for the brake shoes, so it is necessary to place the relatively large and heavy piston and cylinder unit of the hydraulic actuator immediately behind the brake shoes, which is where space is limited, such as in wind In the engine housing of power generation equipment, it will be difficult to provide enough space for the actuator. Another disadvantage of hydraulic actuators is that they are relatively environmentally harmful and expensive. Maintenance is particularly laborious because of the need for suitable Hydraulic oil and seals used to seal the hydrauli...

[0002] Brakes for rotors of wind power generation equipment or similar large-scale equipment must be able to generate a strong braking force, so a sufficiently strong actuator is required. So far, a hydraulic actuator has been used, which directly Creates the engagement for the brake shoes, so it is necessary to place the relatively large and heavy piston and cylinder unit of the hydraulic actuator immediately behind the brake shoes, which is where space is limited, such as in wind In the engine housing of power generation equipment, it will be difficult to provide enough space for the actuator. Another disadvantage of hydraulic actuators is that they are relatively environmentally harmful and expensive. Maintenance is particularly laborious because of the need for suitable Hydraulic oil and seals used to seal the hydraulic system, etc., and for the sake of safe operation, the filling state of the hydraulic oil must be checked in real time. In this case, it is more reasonable to use an electromechanical actuator, but after It has been found that it is difficult to provide sufficient engagement force to the brake shoes using electromechanical actuators
