Brief description of the drawings
Fig. 1 is the overall structure diagram of the pitch control system of the wind power generating set of the utility model embodiment；
Fig. 2 is the side view of the pitch control system of the wind power generating set of the utility model embodiment；
Fig. 3 is the structural representation of the ball screw of the utility model embodiment.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining this
Utility model, it is not used to limit the utility model.
Fig. 1 and Fig. 2 are referred to, Fig. 1 is the whole of the pitch control system of the wind power generating set of the utility model embodiment
Body structural representation, Fig. 2 are the side view of the pitch control system of the wind power generating set of the utility model embodiment.This practicality
The pitch control system of the wind power generating set of new embodiment includes fan blade 10, ball screw 20, elastic component 30 and wheel hub 40；
Wherein, also referring to Fig. 3, for the structural representation of the ball screw of the utility model embodiment.Ball screw 20 includes the
One nut 21, the second nut 22 and spiral shell thick stick 23；One end of spiral shell thick stick 23 is fixed on wheel hub 40, the first nut 21 and the second nut 22
The lower surface of fan blade 10 is individually fixed in, and is sheathed on spiral shell thick stick 23, fan blade 10 can pass through the first nut 21 under wind-force effect
With the second nut 22 gyration is done along spiral shell thick stick 23.Elastic component 30 is sheathed on spiral shell thick stick 23, and elastic component 30 is located at the first nut
21 and second between nut 22, and elastic component 30 is fixedly connected close to one end of the bottom of fan blade 10 with the first nut 21, the other end
It is fixed on spiral shell thick stick 23.
The operation principle of the pitch control system of the wind power generating set of the utility model embodiment is：Fan blade 1 is in wind-force
Effect lower band runner hub 40 rotates, and produces different size of centrifugal force according to wind-force size in rotation process, by this from
Mental and physical efforts cause the first nut 21 and the second nut 22 to drive fan blade 10 to do gyration with spiral shell thick stick 23 for axle, in motion process,
First nut 21 meeting compression elastic piece 30, it is spacing by anglec of rotation progress of the elastic component 30 to fan blade 10, so as to reach basis
Wind-force size automatically adjusts the purpose of the Windward angle of fan blade 10.It is appreciated that wind-force is bigger, it is right in the motion process of the first nut 21
Compression dynamics is bigger caused by elastic component 30, and the Windward angle of fan blade 10 is bigger；Conversely, wind-force is smaller, the first nut 21 moves
During it is smaller to compression dynamics caused by elastic component 30, the Windward angle of fan blade 10 is smaller.
In the utility model embodiment, the quantity of fan blade 10 is at least two or two or more.
In the utility model embodiment, elastic component 30 is spring.
The pitch control system of the wind power generating set of the utility model embodiment passes through fan blade by setting ball screw
Caused centrifugal force drives fan blade to do gyration by axle of ball screw in rotation process, so as to reach according to wind-force size
Automatically adjust the purpose of fan blade hair Windward angle；The utility model is simple in construction, it is easy to accomplish, and electricity consumption is not needed as dynamic
Power, avoid the consumption of energy.
The foregoing description of the disclosed embodiments, professional and technical personnel in the field are enable to realize or new using this practicality
Type.A variety of modifications to these embodiments will be apparent for those skilled in the art, determine herein
The General Principle of justice can be realized in other embodiments in the case where not departing from spirit or scope of the present utility model.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The most wide scope consistent with features of novelty.
