Wind-driven generator yaw device with locking function

Abstract

The invention discloses a wind-driven generator yaw device with a locking function. The wind-driven generator yaw device comprises a tower frame rod, a supporting bearing is fixedly connected in a groove in the top of the tower frame rod, a rotating block is fixedly connected to the inner wall of the supporting bearing, the top of the rotating block penetrates through the supporting bearing and extends to the outside of the supporting bearing, a rotating plate is fixedly connected to the top of the rotating block, a mounting block is fixedly connected to the middle point of the top of the rotating plate, and a rotating shell is fixedly connected to the bottom of the rotating plate. According to the wind-driven generator yaw device with the locking function, a protection plate, limiting rods, a movable ring, limiting blocks, a limiting ring, limiting grooves, a movable plate, first springs, vertical plates, transverse rods, baffle plates and second springs cooperate with one another, sothat the wind-driven generator yaw device has the locking function, the yaw device can be conveniently limited by a worker, the situation that a fan blade of a wind-driven generator deviates from a set angle due to the influence of external force is avoided, the power generation efficiency of the wind-driven generator is improved, and great convenience is brought to a user.

Description

technical field [0001] The invention relates to the technical field of wind-driven generator yaw, in particular to a wind-driven generator yaw device with locking. Background technique [0002] The wind turbine yaw device, also known as the wind-facing device, is a part of the wind turbine nacelle. Its function is to quickly and smoothly align the wind direction when the direction of the wind speed vector changes, so that the wind rotor can obtain the maximum wind energy. The tail rudder is often used to face the wind, and the tail is installed on the tail boom parallel to or at a certain angle with the axis of the wind rotor. In order to avoid the influence of the wake, the tail can also be upturned and installed at a higher position. The common wind turbine The yaw device does not have a locking function. When the wind turbine rotor is rotated to the required angle, it is not convenient for the staff to limit the yaw device. The wind turbine rotor may deviate from the sett...
