Problems solved by technology

When the device locks the fan for a long time, because the wind wheel will shake when it is in the locked state, the existing locking disc 23 and the locking pin 22 will repeatedly contact. When the repeated contact time is too long, the locking pin 22 and the existing locking pin will be locked Between the two parts of the disk 23

Abstract

The invention provides a wind wheel locking device and a wind wheel, and belongs to the technical field of wind power generation. A locking disc and a supporting assembly are included. The locking disc is used for being fixedly connected with the wind wheel of a draught fan. An annular track is formed on the disc face of the locking disc in the circumferential direction. The two supporting ends ofthe supporting assembly are tightly clamped to the annular track in the radial direction of the locking disc so that rotation of the wind wheel relative to the supporting assembly can be locked. Thetwo ends of the supporting assembly move in the radial direction of the locking disc so that wind wheel locking can be achieved, the inserting and pulling actions of a wind wheel lock pin in the axialdirection in the prior art are avoided, and the problem that the wind wheel lock pin in the prior art is prone to getting stuck is solved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind wheel locking device and a wind wheel. Background technique [0002] At present, most of the locking pins of the wind rotor adopt a pin-hole structure or a spline structure that can be inserted and pulled out along the direction of the main shaft of the wind rotor to realize the locking function of the wind rotor when the fan is shut down for maintenance. However, if the maintenance time of the fan is too long, or the fan is shut down for a long time, it will often cause the lock pin to get stuck. [0003] For example, patent CN102251936B discloses a fan and its wind wheel locking device, its structure is as follows: figure 1 As shown, the device realizes the locking function of the wind wheel by inserting or pulling out the locking hole of the locking disc along the direction of the main shaft. figure 1 The middle lock pin 22 can be stretched out or retrac...
