Abstract
The utility model discloses a wind wheel locking device for a wind driven generator set. The wind wheel locking device comprises a hydraulic locking cylinder which is fixed on a wheel hub in a bolt fastening manner and can rotate along with the wheel hub, and a stationary wind wheel locking flange; and the hydraulic locking cylinder is provided with a locking bolt for locking or unlocking the wind wheel locking flange by virtue of stretching and contracting, the hydraulic locking cylinder is connected with a hydraulic control loop for controlling the stretching and contracting of the locking bolt, and the wind wheel locking flange is correspondingly provided with a lining in locking match with the forwardly stretched locking bolt. The utility model aims at providing an automatically-controlled wind wheel locking device for the wind driven generator set, and the wind wheel locking device is simple in structure, small in volume, convenient for operation, and safe and reliable in operation.
Description
[technical field]
The utility model relates to a kind of wind wheel locking device, is the wind-driven generator group wind-wheel locking device furtherly.
[background technique]
When wind power generating set is safeguarded and overhaul, must wind wheel be locked, prevent that the wind wheel rotation from causing security incident.Mostly the wind wheel locking device that adopts on the wind power generating set at present is mechanical manual-lock.Troublesome poeration, rate of fault is higher, and operator are also had certain requirement.Owing to the new wind-power electricity generation type of our company, the design of impeller locking device is in the wheel hub outside in addition, and traditional mechanical manual-lock is not suitable for the impeller locking yet.
[model utility content]
The utility model has overcome the deficiency of above-mentioned technology, provides a kind of simple in structure, and volume is little, and is easy to operate, safe and reliable to operation, the wind-driven generator group wind-wheel hydraulic lock assembly that can control automatically.
For realizing above-mentioned purpose, the utility model has adopted following technical proposal:
A kind of wind-driven generator group wind-wheel locking device; Comprise the hydraulic locking cylinder and the actionless wind wheel lock flange that are fastened on the wheel hub and rotate with wheel hub through bolt; Have on the hydraulic locking cylinder through flexible locking bolt to realize locking and decontroling with the wind wheel lock flange; Be connected with the flexible hydraulic control circuit of control locking bolt on the hydraulic locking cylinder, the corresponding lining that cooperates surely with the locking bolt-lock that before stretches out that is provided with on the wind wheel lock flange.
A kind of as stated wind-driven generator group wind-wheel locking device is characterized in that said locking bolt outer end is a circular cone shape, and lining is provided with and supplies the locking bolt to stretch into and cooperate to reach the conical surface of locking with locking bolt outer end.
A kind of as stated wind-driven generator group wind-wheel locking device, the external diameter that it is characterized in that said hydraulic locking cylinder cylinder body is 325mm, the minimum outer diameter of said locking bolt outer end is 154mm.
Use two wind wheel locking devices on every typhoon machine.When needs carried out the impeller locking, system was to signal of hydraulic pressure locking cylinder, and the locking bolt stretches out under the hydraulic oil effect, and corresponding fitting surface with lining cooperates, and reaches the locking purpose.When needs were decontroled impeller, the locking bolt was withdrawn under the hydraulic oil effect, leaves lining, thereby makes impeller be in free state.Whole process is controlled by system, need not manual work and carries out.
The beneficial effect of the utility model is: the utility model has adopted the hydraulic pressure automatic control mode, has avoided manual operation, has realized outside wheel hub, carrying out the impeller locking.Simple to operate accurate, safe ready, stability is high.
[description of drawings]
The partial sectional view that Fig. 1 uses on wind power generating set for the utility model.
Fig. 2 is a hydraulic locking cylinder structure schematic representation.
Wherein: 1 is the hydraulic locking cylinder, and 2 is wheel hub, and 3 are the locking bolt, and 4 is the wind wheel lock flange, and 5 is lining.
[embodiment]
Below in conjunction with embodiment and accompanying drawing the present invention is described in further detail, but mode of execution of the present invention is not limited thereto.
As depicted in figs. 1 and 2; A kind of wind-driven generator group wind-wheel locking device; Comprise through bolt and be fastened on the hydraulic locking cylinder 1 that rotates with wheel hub 2 on the wheel hub 2 and be fixed on actionless wind wheel lock flange 4 on the Transmitted chains casing; Have on the hydraulic locking cylinder 1 through flexible locking bolt 3 to realize locking and decontroling with wind wheel lock flange 4; Be connected with the flexible hydraulic control circuit of control locking bolt on the hydraulic locking cylinder 1, the lining 5 of corresponding locking bolt 3 lock fit that are provided with and before stretch out on the wind wheel lock flange 4, lining 5 are provided with the conical surface 52 that supplies locking bolt 3 to stretch into and cooperate with locking bolt 3 outer ends.Wherein, the external diameter of hydraulic locking cylinder cylinder body is a=325mm, and locking bolt 3 outer ends are circular cone shape, and the minimum outer diameter of locking bolt outer end is b=154mm.
The utility model adopts hydraulic way to carry out the wind wheel locking.When needs carried out the impeller locking, system was to 1 one locking signals of hydraulic pressure locking cylinder, and locking bolt 3 stretches out under the hydraulic oil effect and cooperates with the lining 5 corresponding conical surfaces 52, reaches the locking purpose.When needs were decontroled impeller, system decontroled signal to 1 one in hydraulic pressure locking cylinder, and locking bolt 3 is withdrawn under the hydraulic oil effect and left lining 5, thereby makes impeller be in free state.
