Description
Technical field
The utility model relates to wind power generation field, is specially a kind of fan blade of wind generating set deicer.
Background technique
Wind power generating set is generally located at high mountain and border areas, and these winters are cold, high humidity.The cold little water droplet of a large amount of subfreezing mistake is there is in the environment of high humidity, low temperature, super-cooling waterdrop is now in metastable condition, when blade rotates in icing cloud layer, these are crossed cold little water droplet in dropping process, strike that wind wheel blade surface is rapid afterwards to start to freeze at blade surface, occur blade windward to region icing phenomenon.
Blade icing all can bring certain impact to wind field, unit operation and personal security, reduces generating efficiency, increases performance load and noise, even jeopardizes the safety of blower fan and field maintenance person.Therefore blade de-icing work seems particularly important.
Take the mainly artificial deicing of the mode of deicing at present.Artificial deicing by means of operating platform, inefficiency, and operational hazards coefficient is high.Also have and adopt bulged tube technology deicing.Be exactly paste rubber swelling pipe at the blade inlet edge easily frozen, utilize huge blade centrifugal load to make its automatic expansion, after expanding, ice sheet self-heating comes off.This kind of technology makes blade gross distortion, larger on blade impact in working life.
Model utility content
Model utility object: provide a kind of fan blade of wind generating set deicer, to solve the problems of the technologies described above.
Technological scheme: the utility model is achieved through the following technical solutions:
A kind of fan blade of wind generating set deicer, comprise control cabinet, electromagnetic shielding plate, twisted-pair feeder, electromagnetic generator, blade body, magnetic conduction iron net, icing detector, lightning protection line and thunder terminal box, described blade body is windward to being covered with magnetic conduction iron net, and root position is provided with electromagnetic shielding plate; Described blade body is windward to being also provided with icing detector, and icing detector is connected with control cabinet by twisted-pair feeder; Described electromagnetic generator is arranged on the inside of blade body, and near magnetic conduction iron net; Described electromagnetic generator is connected with control cabinet; Described magnetic conduction iron net is connected by lightning protection line with lightning prevention connection box.
The beneficial effect of employing technique scheme is:
1. when carrying out wind wheel blade deicing, unit need not be shut down, and keeps better unit availability;
2. the utility model does not need manual operation, and system identifies icing degree automatically, carries out corresponding anti-ice operation;
3. the utility model structure is simple, and easy for installation, cost is low, compares to be beneficial to and promotes on a large scale.
Accompanying drawing explanation
Fig. 1 is structure of the present utility model and principle schematic;
1. control cabinets, 2. electromagnetic shielding plate, 3. twisted-pair feeder, 4. electromagnetic generator, 5. blade body in figure, 6. magnetic conduction iron net, 7 icing detectors, 8. lightning protection line, 9. thunder terminal box.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further;
As shown in Figure 1, the utility model provides a kind of fan blade of wind generating set deicer, comprise control cabinet 1, electromagnetic shielding plate 2, twisted-pair feeder 3, electromagnetic generator 4, blade body 5, magnetic conduction iron net 6, icing detector 7, lightning protection line 8 and thunder terminal box 9, described blade body 5 is windward to being covered with magnetic conduction iron net 6, and root position is provided with electromagnetic shielding plate 2; Described blade body 5 is windward to being also provided with icing detector 7, and icing detector 7 is connected with control cabinet 1 by twisted-pair feeder 3; Described electromagnetic generator 4 is arranged on the inside of blade body 5, and near magnetic conduction iron net 6; Described electromagnetic generator 4 is connected with control cabinet 1; Described magnetic conduction iron net 6 is connected by lightning protection line 8 with lightning prevention connection box 9, prevents thunder and lightning from hitting magnetic conduction iron net 6, brings infringement to blade.
Introduce use installment state of the present utility model below.
After blade body 5 freezes, icing detector 7 obtains signal, by twisted-pair feeder 3 by signal transmission to control cabinet 1, the thickness that control cabinet 1 freezes according to blade body 5 sends instruction to electromagnetic generator 4, that electromagnetic generator 4 generates electromagnetic waves, magnetic conduction iron net 6 is generated heat, thus ice is removed from blade body 5.Electromagnetic shielding plate 2 can effectively prevent and reduce the interference of electromagnetic generator 4 pairs of control cabinets 1.
