Description
Technical field
This utility model relates to a kind of wind power generation plant, specifically, is a kind of self protection type's wind-force
TRT, belongs to wind power generation plant technical field.
Background technology
It is all fixed-wing fan blade that the prior art overwhelming majority puts into the wind-power electricity generation equipment of application, so
There is certain maximum limit wind-force, exceed this wind-force rank and will damage wind-force electrical machinery and related
Installing mechanism.So safety and reliability have certain hidden danger.Current solution is as far as possible
Improve the strength grade of fan blade, so that it is guaranteed that motor and mounting structure thereof are unlikely under the conditions of big wind-force
Damage.But this solution is relatively costly, manufactures and designs difficulty the biggest.
Summary of the invention
This utility model technical issues that need to address are: existing wind power generation plant, use fixing
Wing fan blade, has certain maximum limit wind-force, exceed this wind-force rank will damage wind-force electrical machinery and
Its related installing mechanism, current solution is to improve the strength grade of fan blade as far as possible, thus
Guarantee that motor and mounting structure thereof are unlikely to damage under the conditions of big wind-force, but this solution cost
Higher, manufacture and design difficulty the biggest.
This utility model takes techniques below scheme:
A kind of self protection type's wind power generation plant, including fan blade 1, fan blade rotating shaft 2, fixing seat 3, in
Heart rotating shaft；Described fan blade 1 is evenly arranged in around described central rotating shaft, and by bracing frame with in
Heart rotating shaft is relatively fixed；Described fan blade 1, in vertical arc surface structure, is free end inside it, outward
Side is rotationally connected with fan blade rotating shaft 2；The lower end of described fan blade rotating shaft 2 is fixed on fixing seat 3；When
When wind-force increases, the free end inside described fan blade 1 is under the action of the forces of the wind around described fan blade rotating shaft 2
Rotate, reduce the lifting surface area of fan blade, thus fan blade is protected.
Further, the bottom of described fixing seat 3 arranges a spike 4, for contacting with ground.
Further, the top of described fan blade rotating shaft 2 arranges fixed disc 6, on described fixed disc
Portion is fixing with upper support frame 5 to be connected, and the center of described upper support frame 5 and described central rotating shaft are positioned at same
On one vertical curve, described upper support frame 5 is for fixing with exterior object, thus strengthens described self-insurance
Protect the fixing of formula wind power generation plant.
The beneficial effects of the utility model are:
1) being that fan blade arranges fan blade rotating shaft, fan blade rotating shaft is arranged on outer end, and the inner is free end, can be certainly
Regulated by rotation；
2) when wind-force is excessive, the problem that fan blade is impaired is solved；
3) design ingenious, fan blade according to wind-force size automatic rotary modulation joint after fan blade axis of rotation residing
Position；
4) effectively prevent motor and mounting structure stress thereof from damaging；
5) use rotary type fan blade design when wind-force rank is excessive blade can automatically pivot from
And reduce whole device by monsoon intensity protect wind generator itself；
6) also use the half special leaf design of barrel shape, this be designed to so that wind-engaging is fuller can
Device is operated under less wind-force and improves the utilization rate to wind energy
7) simple in construction, cost is controlled, has the prospect of wide popularization and application.

Detailed description of the invention
With specific embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
See Fig. 1-Fig. 4, a kind of self protection type's wind power generation plant, including fan blade 1, fan blade rotating shaft 2,
Fixing seat 3, central rotating shaft；Described fan blade 1 is evenly arranged in around described central rotating shaft, and passes through
Bracing frame is relatively fixed with central rotating shaft；Described fan blade 1, in vertical arc surface structure, inside it is
Free end, outside is rotationally connected with fan blade rotating shaft 2；The lower end of described fan blade rotating shaft 2 is fixed on fixing
On seat 3；When wind-force increases, the free end inside described fan blade 1 is under the action of the forces of the wind around described
Fan blade rotating shaft 2 rotates, and reduces the lifting surface area of fan blade, thus protects fan blade.
Seeing Fig. 1-Fig. 2, the bottom of described fixing seat 3 arranges a spike 4, for contacting with ground.
Seeing Fig. 1, the top of described fan blade rotating shaft 2 arranges fixed disc 6, described fixed disc top
Fixing with upper support frame 5 and be connected, the center of described upper support frame 5 is positioned at same with described central rotating shaft
On vertical curve, described upper support frame 5 is for fixing with exterior object, thus strengthens described self-shield
Fixing of formula wind power generation plant.
This utility model use the fan blade design of rotary type when wind-force rank is excessive blade can automatically around
Axle rotate thus reduce whole device by monsoon intensity protect wind generator itself；In addition this device is also adopted
With the half special leaf design of barrel shape, this is designed to enable to device so that wind-engaging is fuller and exists
Under less wind-force, operating improves the utilization rate to wind energy.This device belongs to wind-power electricity generation equipment field, main
The self-shield problem of wind-power electricity generation to be solved equipment.
