Embodiment
In order to facilitate the understanding of the purposes, features and advantages of the present invention, below in conjunction with the accompanying drawings to the present invention
Embodiment be described in detail.It should be noted that accompanying drawing of the present invention uses using simplified form and non-essence
Accurate ratio, only for the purpose of facilitating and clarifying the purpose of the embodiments of the invention.
For in the prior art the defects of, the present invention original blower fan construction on the basis of, creative proposing can roll over
This imagination of folded blade, largely improves survival ability and the loaded limit of the blower fan under bad working environments.In a century
One meet even 10000 years one meet bad working environments under, the Anti-Typhoon blower fan of the folding-jib can by itself leaf folding come reduce blade by
Power and tower foundation Moment, there is saving to withdraw cost, reduce extreme loads infringement, ensure that blower fan normal table work etc. is all
More advantages.
As shown in figure 1, the invention provides a kind of Anti-Typhoon blower fan of folding-jib, including cabin 1, wheel hub 2, rotating shaft, three
3, three support connectors 4 of blade.The first end of rotating shaft is arranged on inside cabin 1, and cabin 1, wheel hub 2 are stretched out in the second end of rotating shaft
The second end of rotating shaft is socketed in, each blade 3 supports the another of connector 4 by supporting connector 4 to be arranged on the periphery of wheel hub 2
One end is connected to the opening position rearward of wheel hub 2.Opening position is provided with groove to wheel hub 2 rearward, and convenient support connector 4 one section is hinged
Head moves forward and backward on the hub 2.Support connector 4 can be gathered or open up to wheel shaft with movable vane piece 3 by shrinking or extending
Open.Three blades 3 are separately mounted to 120 degree of equally divided positions of the periphery of wheel hub 2.
As shown in figure 3, support connector 4 includes be hinged rotating shaft, the first hinge of be hinged rotating shaft is fixed on the root of blade 3
Portion, the second hinge of be hinged rotating shaft are fixed on the opening position rearward of wheel hub 2.Support connector 4 also includes hydraulic strut, hydraulic pressure support
The first end of bar is connected to blade 3, and the second end of hydraulic strut is connected to wheel hub 2.When hydraulic strut extends, one end of strut
Articulated joint is moved rearwards along wheel hub groove, and blade 2 deploys therewith；When hydraulic strut shrinks, one end articulated joint edge wheel of strut
Hub groove moves forward, and blade 2 is gathered therewith.When blower fan rotates, hydraulic strut can together rotate with wheel hub 2.Hydraulic strut by
Hydraulic pump control, hydraulic pump receive the control of ground control centre fan control module.
Fan control module by blower fan operating personnel's manual control.Control mode is as follows：Fan engine room rear portion is equipped with wind
Fast sensor, air velocity transducer can pass to wind speed information ground control centre, and control centre staff passes through to institute
The comprehensive analysis and judgement for gathering wind speed information take corresponding control measure, are returned to control information by ground control centre
To the hydraulic pump, the contraction and elongation of hydraulic pump control hydraulic strut, and then control the expansion of the blade 3 or gather.It is excellent
Selection of land, air velocity transducer are arranged at the afterbody center of fan engine room 1.
The present invention provides a kind of Design Conception of novel wind generator, by the connected mode of the blade of blower fan and wheel hub by
Being rigidly connected originally makes remote controlled support connector connection into, and fan engine room rear portion is equipped with air velocity transducer.In platform
Under the bad working environments such as wind, wind speed information can return signal to ground control centre by sensor, and ground control centre passes through remote
Journey station command shrinks hydraulic strut, and blade always gather by the folding of wind direction, reduces the lifting surface area of blower fan, so as to certain
Acutely injured caused by reduction typhoon is possible to fan blade in degree.In addition, reducing wind load to caused by fan blade
While high forces, the opplied moment suffered by tower base foundation also accordingly reduces, and can effectively solve blower fan and meet with the conditions of typhoon
To serious problems such as damages.
