The utility model relates to the technical field of wind power plants, in particular to a gas-heated deicing device for a fan blade.

[ background of the utility model ]

When the wind power station is positioned in a mountain area with the altitude of 1900-2100 m, the air temperature of the area where the wind power station is positioned is lower than-5 ℃ for a long time, the blades of the fan can accumulate ice, the blades can be broken when the ice accumulation is serious, the personnel safety of the wind power station is threatened, meanwhile, the efficiency of the wind power station is reduced due to the blade icing, the annual energy production loss is 7% -9%, and the serious electric quantity loss and the economic loss are caused to the wind power station.

In view of the above, it is desirable to provide a new type of air-heated deicing device for fan blades to overcome the above-mentioned drawbacks.

[ Utility model ] content

The utility model aims to provide a gas-heated deicing device for fan blades, which can remove ice on the blades, avoid the breakage of the blades and reduce the power generation loss of a wind power plant.

In order to achieve the purpose, the utility model provides a gas-heated deicing device for fan blades, which comprises a blade main body, a gas flow driving piece, a heater and a heat conducting pipe, wherein the gas flow driving piece is arranged on the blade main body; the blade main part has the inner chamber, gaseous flow driving spare, heater and heat pipe all set up in the inner chamber, just the heater connect in gaseous flow driving spare and heat pipe between.

Preferably, the blade body includes a head end and a tail end far from the head end, the gas flow driving member and the heater are disposed toward a position close to the head end, and the heat pipe extends to the tail end.

Preferably, the gas flooding member and the heater are both electrically connected with an external power supply.

Preferably, the gas drive member is a centrifugal fan.

Compared with the prior art, the air-heating deicing device for the fan blade provided by the utility model has the beneficial effects that: the gas drives the flow piece and blows the hot gas flow that the heater heating produced and circulate in the heat-conducting pipe, can make the overall structure of blade main part keep higher temperature, can detach the freezing on the blade, avoids the blade fracture, can also reduce the power generation electric quantity loss of wind-powered electricity generation field.

[ detailed description ] embodiments

In order to make the objects, technical solutions and advantageous effects of the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and the detailed description. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the utility model, are intended for purposes of illustration only and are not intended to limit the scope of the utility model.

It will be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like are used in the orientation or positional relationship indicated in the drawings for ease of description and simplicity of description, and do not indicate or imply that the referenced devices or elements must be in a particular orientation, constructed and operated in a particular orientation, and are therefore not to be considered limiting.

It is also noted that, unless expressly stated or limited otherwise, the terms "mounted," "connected," "secured," "disposed," and the like are intended to be inclusive and mean, for example, that they may be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. To those of ordinary skill in the art, the above terms may be specifically defined in the present invention according to the specific circumstances.

Furthermore, the terms "first", "second", and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first", "second", may explicitly or implicitly include one or more of that feature. Further, the meaning of "a plurality" or "a plurality" means two or more unless specifically limited otherwise.

As shown in fig. 1, the utility model provides a gas-heated deicing device for fan blades, comprising a blade body 1, a gas flow driving member 2, a heater 3 and a heat conducting pipe 4; the blade body 1 is provided with an inner cavity, the gas flow driving part 2, the heater 3 and the heat conduction pipe 4 are arranged in the inner cavity, and the heater 3 is connected between the gas flow driving part 2 and the heat conduction pipe 4. In this embodiment, the gas flooding member 2 is a centrifugal fan.

Therefore, when the wind power plant fan is applied to the region and the temperature is in a cold environment for a long time, the heater 3 heats the inner cavity of the blade, the gas driving piece 2 blows hot gas flow generated by heating the heater 3 to circulate in the heat conduction pipe 4, so that the integral structure of the blade body 1 can keep a higher temperature, and the blade can be prevented from being frozen.

Further, the blade body 1 includes a head end and a tail end far away from the head end, the gas flow driving member 2 and the heater 3 are disposed toward a position near the head end, and the heat pipe 4 extends to the tail end. Thus, when the hot air flows from the heat pipe 4 to the tail end, the hot air can flow back to the head end in the inner cavity of the blade body 1 and is discharged, so that the temperature of the blade body 1 is more balanced.

Further, the gas drive flow member 2 and the heater 3 are both electrically connected with an external power supply.

The utility model is not limited solely to that described in the specification and embodiments, and additional advantages and modifications will readily occur to those skilled in the art, so that the utility model is not limited to the specific details, representative apparatus, and examples shown and described herein, without departing from the spirit and scope of the general concept as defined by the appended claims and their equivalents.
