Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art, aiming at the problem that the existing anti-typhoon type generating set completely locks or completely releases the wind wheel, resulting in a large load on the whole set, and proposes a braking system for the anti-typhoon wind generating set The flexible wind wheel locking device adopts a flexible wind wheel locking design scheme, which allows the wind wheel to swing within a certain angle and provides a restoring force to the wind wheel. When the wind wheel deviates from the positive "Y" position, the greater the restoring force , can greatly reduce the load of the wind turbine and the whole machine, and greatly reduce the difficulty of the overall design of the wind turbine

Embodiment 1

[0025] The flexible wind wheel locking device provided in this embodiment is mainly used for the braking system of typhoon-resistant wind power generating sets, such as figure 1 As shown, the braking system is mainly composed of the wind wheel locking disc 16, the front end flange 3 of the gearbox, and the wind wheel locking pin assembly 2. 17 is fixed by bolt connection, and the gearbox front end flange 3 is a part of the gearbox of the wind power generating set, which is respectively connected to the generator (not shown in the figure) of the wind power generating set and the nacelle shell 18 by bolt connection and fixing. The wind wheel lock pin assembly 2 includes a wind wheel lock pin 201 and a driving device (not shown in the figure) for driving the wind wheel lock pin 201 to extend or retract. When the wind wheel needs to be locked, the wind wheel is first locked The locking hole on the disk 16 is aligned with the wind wheel locking pin 201, and then the wind wheel lock...

Embodiment 2

[0036] see Figure 6 As shown, the difference from embodiment 1 is that this embodiment only adopts one wind wheel locking pin assembly 2, and the shell of the wind wheel locking pin assembly 2 is connected with one end of the swing trolley 1, and is solidly integrated as a whole. Similarly, the two Two rope receiving devices 8 are symmetrically distributed on the left and right sides of the front flange 3 of the gearbox, the first wire rope group 801 of one of the rope receiving devices 8 is connected to the outer shell of the wind wheel locking pin assembly 2, and the other rope receiving device 8 The first wire rope group 801 of the device 8 is connected with the other end of the swing trolley 1 .

Abstract

The invention discloses a flexible wind wheel locking device for a braking system of an anti-typhoon wind generating set. With the adoption of a flexible wind wheel locking design scheme, the flexiblewind wheel locking device comprises two rope retracting devices which are symmetrically distributed on the left side and right side of a front flange of a gearbox and connected with the left end andthe right end of a swinging trolley; and the swinging trolley is integrated with a housing of a wind wheel locking pin assembly of the braking system, and can move in an arc guide slot hole of the front flange of the gearbox to drive the rope retracting device on the left side or the right side to be tightened, and at the same time to drive one of guide posts in the center of the bottom of the front flange of the gearbox to be pulled out, so that a spring sleeving the guide post is compressed to provide restoring force to a wind wheel. According to the invention, the wind wheel is allowed to swing within a certain angle, and the greater the angle deviation from the positive Y position is, the greater the restoring force is, so that the load of the wind wheel and the whole machine is greatly reduced, and the overall design difficulty of the wind generating set is greatly reduced.

Description

technical field [0001] The present invention relates to the technical field of braking system design of typhoon-resistant wind power generating sets, in particular to a flexible wind wheel locking device for the braking system of typhoon-resistant wind power generating sets, which is used to lock the wind wheel in anti-typhoon working conditions, so that the wind wheel It can only swing within a certain angle range along the transmission axis, and provide suitable torsional rigidity. Background technique [0002] It is well known in the industry that for megawatt-class three-blade typhoon-resistant wind turbines, pitch control is generally used to feather the three blades, and the wind wheel is free to idle to avoid excessive load on the whole machine. For the three-bladed anti-typhoon wind turbine, after feathering the three blades, the wind rotor needs to be locked at the horizontal position of the blades, so that the load on the wind turbine is minimized. When the wind r...
