Abstract
The invention discloses an anti-freezing fan blade. A heating device made of a positive temperature coefficient (PTC) thermistor material is arranged in the fan blade. The heating device made of the PTC thermistor material is applied to manufacturing of the fan blade; due to the characteristic of the PTC thermistor material, effects of heating and freezing prevention for the blade are achieved; and the anti-freezing fan blade has the characteristics of simple structure, high reliability, long service life, safety and energy conservation and is easy to maintain.
Description
Technical field
The present invention relates to the fan blade field, particularly, relate to a kind of anti-freezing fan blade.
Background technique
Current, wind power generating set has got into large-scale application period, and the wind-power electricity generation cleanliness without any pollution does not have fuel cost yet, is one of generation mode of advocating energetically.But the ice formation issues of fan blade is perplexing wind-powered electricity generation operator always; Everybody is in the anti-freezing method of active research fan blade; The method of mainly using at present is that the mode of electric drier or electric heating wire heating is come to the blade heating, prevents that blade from freezing or the purpose of icing back deicing thereby reach.But said method all has deficiency, and the mode of electric drier needs motor and blower, and it is local big to take blade, and hot area is inhomogeneous, complex structure.Use electric heating wire, the self-temperature of electric heating wire is high, and is just high for safe requirement, therefore designs more complicated too.
Summary of the invention
The objective of the invention is to overcome the shortcoming and defect of above-mentioned existing technology, a kind of anti-freezing fan blade is provided, that its heating equipment that adopts has is simple in structure, take the characteristics that blade occupies a narrow space, hot area is even, safe in utilization.
To achieve these goals, the present invention adopts following technological scheme:
A kind of anti-freezing fan blade is provided with PTC thermistor material heating equipment in the said fan blade.
Further, said PTC thermistor material heating equipment comprises the PTC thermistor material heater band that has connector lug, and said connector lug is connected with tenminal block through lead, and tenminal block is connected with the power supply that gets into blade through switch.
Further, said PTC thermistor material heater band and corresponding tenminal block thereof have many covers, and to overlap tenminal block parallel with one another more.
Further, said PTC thermistor material heater band and corresponding tenminal block, switch thereof have many covers, and to overlap tenminal block parallel with one another through many cover switches more.
Further, said PTC thermistor material heater band is laid in the interlayer of blade or is laid on the internal surface of blade.
Further, said PTC thermistor material heater band and fan blade are the fixing of pemanent type.
Further, said tenminal block is arranged in the tenminal block box in the fan blade blade root.
Compared with prior art, the present invention has following beneficial effect:
The present invention is according to the heating characteristics of fan blade; In fan blade, adopt PTC thermistor material heating equipment; The PTC thermistor is the semiconductor resistor that a kind of typical case has temperature sensitivity, and when surpassing certain temperature, its resistance value is along with the rising of temperature is increasing of step evolution.Be characterized in: 1, sensitivity is higher; 2, operating temperature range is wide; 3, easy to use; 4, be prone to be processed into complicated shape, can be mass-produced; 5, good stability, overload capacity are strong.
Therefore, the present invention is applied in PTC thermistor material heating equipment in the manufacturing of fan blade, utilizes the characteristic of PTC thermistor material; Make blade reach the anti-freezing effect of heating; It is simple in structure that this anti-freezing blade is had, and reliability is high, is easy to safeguard; Long service life, the characteristics of energy-saving safe.
Through accompanying drawing and embodiment, technological scheme of the present invention is done further detailed description below.
Description of drawings
Fig. 1 is structural representation of the present invention (in the interlayer of blade, laying);
Fig. 2 is structural representation of the present invention (internal surface at blade is laid);
Fig. 3 is the terminal connections schematic representation.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for explanation and explains the present invention, and be not used in qualification the present invention.
Like Fig. 1,2, shown in 3, a kind of anti-freezing fan blade of the present invention is provided with PTC thermistor material heating equipment 2 in fan blade 1.The present invention is applied in the PTC thermistor material in the manufacturing of fan blade, utilizes the characteristic of PTC thermistor material, makes blade reach the anti-freezing effect of heating.
Wherein, PTC thermistor material heating equipment 2 comprises the PTC thermistor material heater band 21 that has connector lug; Connector lug through lead 22 be arranged on the fan blade blade root in the tenminal block box in tenminal block 23 be connected, tenminal block 23 is connected through the power supply 24 of switch with the entering blade.
Wherein, PTC thermistor material heater band 21 and corresponding tenminal block 23 thereof can have many covers, and to overlap tenminal block 23 parallel with one another more, also can be parallel with one another through many cover switches or overlap tenminal block 23 more.
Wherein, the characteristics of PTC thermistor material heater band are following:
According to blade shape, confirm the paving location of PTC thermistor material heater band in blade, PTC thermistor material heater band shape and width that design is fit to.
The PTC thermistor material heater band that designs is laid in the leaf production process, can be laid in the interlayer of blade (as shown in Figure 1) as fiber glass material, also can be laid on the internal surface (as shown in Figure 2) of blade.Can carry out the fixing of pemanent type.
The temperature characteristic of PTC thermistor material heater band is chosen in the suitable scope, and the characteristic variations that does not influence blade material with assurance is a standard.Most PTC thermistor materials can satisfy such range of temperature.Exceed this scope, the resistance value of material rises rapidly, no longer heating.
The power of PTC thermistor material heater band calculates according to residing external condition of blade and blade profile.
What should explain at last is: the above is merely the preferred embodiments of the present invention; Be not limited to the present invention; Although the present invention has been carried out detailed explanation with reference to previous embodiment; For a person skilled in the art, it still can be made amendment to the technological scheme that previous embodiment is put down in writing, and perhaps part technical characteristics wherein is equal to replacement.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
