Description
Technical field
The invention belongs to wind energy conversion system, relate generally to a kind of there is the anti-icing and wind-force of deicing capability
Machine blade.
Background technology
Having the wind field of outstanding wind-resources, long along with icing phenomenon, pneumatic equipment blades freezes
After can make wind power generating set lower power production, even shut down, the quality of icing rear blade is not
Balance can cause the fatigue damage bottom tower, and on rotating vane, ice cube gets rid of from high-altitude and also can
Cause security incident, therefore prevent pneumatic equipment blades from freezing or remove rapidly after blade freezes
Ice is a focus of current wind generating technology research.Existing correlational study shows, wind-force
Machine blade freezes and focuses mostly at tip segment, therefore surface at the blade inlet edge of tip segment
When temperature exceedes freezing temperature, pneumatic equipment blades can be effectively suppressed to freeze.Hot-air at present
Cyclic deicing has preferable effect, but in real process, it is necessary to heat whole blade
Internal cavity ability heater blade, consumes energy bigger.Consider from the version of blade, due to
Tip segment cavity is narrow and small, it is impossible to arrange complicated airflow line；And it is empty near the cavity of blade root
Between bigger, it may appear that the problem that heats is inconspicuous or pipeline arrangement is complicated.How to improve
Blade hot gas cycle situation, accelerating blade intensification efficiency becomes and must solve the technical problem that.
Summary of the invention
The purpose of the present invention is aiming at the problem that above-mentioned prior art exists, it is provided that in a kind of
Set up defences the pneumatic equipment blades of the hot rotating sprayer of deicing gas, make thermal current emphasis heater blade leading edge
Part, reaches to improve the thermal efficiency, significantly promotes the purpose of pneumatic equipment blades anti-deicing effect.
The object of the present invention is achieved like this: the hot rotating sprayer of deicing gas of setting up defences in a kind of
Pneumatic equipment blades includes pneumatic equipment blades, is fixedly mounted with heat on the root of described pneumatic equipment blades inner end
Aerator, air-guide main tube is arranged in pneumatic equipment blades intracavity, the inlet end of described air-guide main tube
It is connected with hot-air blower, at the described fixed main backstop of pneumatic equipment blades intracavity, inducing QI looped pipeline
Being packed on main backstop, the exhaust end of described air-guide main tube is connected with inducing QI looped pipeline, in institute
By secondary bracing frame, fan, the input of shaking the head of oscillating mechanism are installed in stating inducing QI looped pipeline tube chamber
Installation coaxially connected with fan, is joined by bellows on described inducing QI looped pipeline one side end
Dress Fan spray head, the end that waves of described oscillating mechanism is connected with Fan spray head.
Pneumatic equipment blades leading edge housing can effectively be heated by the present invention, simplifies pneumatic equipment blades
Pipe arrangement, improves thermal current utilization rate, and heating region is concentrated simultaneously, and according to actual feelings
Nozzle angle is adjusted by condition, improves the efficiency of heating surface, and effective suppression pneumatic equipment blades is sent out
Raw ice formation issues, has and prevents blade from freezing and remove that blade icing ability is strong, using effect
Good, novel structure, reasonable, compact feature.

Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present invention is described in detail.Set up defences in one and remove
The pneumatic equipment blades of the hot rotating sprayer of BINGQI includes pneumatic equipment blades 2, at described wind energy conversion system leaf
Being fixedly mounted with hot-air blower 1 on the root of sheet 2 inner end, air-guide main tube 3 is arranged in pneumatic equipment blades 2
Intracavity, the inlet end of described air-guide main tube 3 is connected with hot-air blower 1, at described wind energy conversion system
The fixed main backstop of blade 2 intracavity 5, inducing QI looped pipeline 4 is packed on main backstop 5, institute
The exhaust end stating air-guide main tube 3 is connected with inducing QI looped pipeline 4, at described inducing QI looped pipeline 4 tube chamber
Fan 10 installed by the interior pair bracing frame 9 that passes through, shake the head input and the fan 10 of oscillating mechanism 8
Coaxially connected installation, is equipped with by bellows 6 on described inducing QI looped pipeline 4 one side end
Fan spray head 7, the end that waves of described oscillating mechanism 8 is connected with Fan spray head 7.Described shake
Head mechanism 8 includes lever disengaging type oscillating mechanism or lifts group formula oscillating mechanism.
Need to carry out anti-icing operation or wind-force in pneumatic equipment blades 2 is in the environment of easily icing
Have occurred and that on machine blade 2 that, when icing needs to carry out deicing operation, hot-air blower 1 is opened,
After the cold air of extraction pneumatic equipment blades 2 intracavity heating, hot-air is injected into air-guide main tube
In 3, and making hot-air have certain pressure, hot-air is flowed into inducing QI by air-guide main tube 3
Looped pipeline 4 promotes fan 10 rotate, drive oscillating mechanism 8 input to rotate, make head-shaking machine
Structure 8 works, and the end that waves of oscillating mechanism 8 drives Fan spray head 7 to swing, thermal current
Spray through Fan spray head 7, fan-shaped air the most inswept pneumatic equipment blades 2 housing of ejection
Leading edge inner surface, owing to thermal current has pressure, directly impinges the shell of pneumatic equipment blades 2
On body, it is heated, it is not necessary to cavity or corresponding air flue to pneumatic equipment blades 2 are carried out
Overall heating.In actual job work process, the pressure of the thermal current in scalable air flue comes
Control the rotating speed of fan 10, and then control the hunting frequency of Fan spray head 7.
