Description
Technical field
The utility model is related to a kind of deicer, the automatic de-icing of specifically a kind of blade of wind-driven generator fills
It sets.
Background technology
Wind-power electricity generation is that the kinetic energy kept watch switchs to electric energy.Wind energy as a kind of clean regenerative resource, increasingly by
The attention of countries in the world.Wind-power electricity generation holds international energy-saving and emission-reduction in Chinese following realize as green clean reproducible energy
Increasingly important role will be played in promise.Wind-driven generator is mainly by blade, generator, mechanical part and electric component group
At.One of core component of wind power generating set blade also develops towards structure large-scale direction.The blade of wind-driven generator
Main function is to capture wind, and wind-force is transmitted to rotor axis.The Wind Power Development of China is concentrated mainly on three northern areas of China, and three
The feature of backlands area maximum is to undergo the low temperature environment of significant period of time every year, this is to blade of wind-driven generator or even whole
A wind turbine all brings serious test.Under normal circumstances, it encounters sleety weather as low as after to a certain degree in temperature and easily occurs
Blade ice condition, blade, which freezes, most directly to be influenced to be that blade overload, blade ice load can be caused to be unevenly distributed, and is in turn resulted in
Wind turbines output drop, serious icing will cause wind turbine power generation amount to fall sharply, or even blade broken, wind-power electricity generation occurs
The accidents such as machine damage, cause huge economic losses.On the other hand in blade rotary course, easily when ice sheet adhesive force declines
There is ice cube to fall off, causes operation accident, it is also possible to bulk ice cube occur and fall situation of hurting sb.'s feelings.It is difficult to fall off after blade icing,
There is no anti-icing, deicing function blade that can only wait for shine upon, after the ice-out on blade falls off, Wind turbines could weigh
Start shipment row.
Now, icing detection technique can accurately detect blowing machine icing conditions and position, but there has been no automatic or manuals
The device of the automatic de-icing of control has seriously affected the generating efficiency and service life of wind turbine.Currently, the active of wind-driven generator
Ice-melt, ice control mainly have manual deicing and blow hot-air method.Manual deicing is manual idle running wind turbine, so only can be to leaf
There are one mitigations for piece surface icing phenomenon.It is to be removed by conveying hot-air to hollow blade with reaching to blow hot-air method
The purpose of blade surface icing is gone, but in practice, there is a problem of that thermal loss is grown with the deicing period greatly.Cause
This, how according to the blade icing conditions detected, the deicing by the way of startup deicer is automatically or manually controlled, is mesh
Problem preceding and to be solved has great engineering application value.
Now it is required to one kind is simple in structure, easy to use, thermal loss is small, the deicing dress of the fast wind-driven generator of deicing
It sets.
Invention content
The purpose of this utility model is to provide for a kind of automatic deicer of wind-driven generator, and the ice is except system structure letter
Single, easy to use, deicing is fast, deicing effect is good, and thermal loss is few.
The technical solution of the utility model is：
The automatic deicer of blade of wind-driven generator includes multiple electrical-heating films and deicing control system, blade surface
Easily two layers of electrical-heating film is arranged in the corresponding blade interior of ice forming locations, is parallel way between each electrical-heating film, described
Socket is provided on the wheel hub of blade, socket is connect by lead with film, the electronic lead screw of setting in the cabin of wind-driven generator,
Electronic lead screw is connect by connecting rod with plug, and plug is connect with deicing control system by conducting wire.
The utility model has the beneficial effects that：
The automatic deicer of the utility model blade of wind-driven generator is in blade manufacturing process in easy ice forming locations part
Paralleling two beds electrical-heating film is set, is controlled by outside and heats automatic de-icing.Scenario-frame is simple in this way, and deicing effect is good, removes
Speed of icing is high.One independent heating unit of each layer of conduct, bilayer in parallel are to can guarantee that failure influences minimum zone simultaneously
Extend can deicing service life.Electrical-heating film mainly prevents occurring frangibility situation in heater strip production process, with reality
The existing heating function service life extends, to improve blade service efficiency.
Description of the drawings
Fig. 1 is the sectional view that electrical-heating film part is arranged in the application blade.
Fig. 2 is the application electrical-heating film circuit diagram.
Fig. 3 is electrical-heating film and deicing control system structural schematic diagram.
Specific implementation mode
In order to overcome drawbacks described above, harm, the utility model to provide one kind in blade manufacturing process, accumulated using big data
It is tired, increase the mode of heating layer, that is, electrical-heating film built in segmented at easy icing, is automatically or manually controlled and is opened by outside
The design scheme of dynamic mode of heating deicing.
Concrete structure is that the automatic deicer of blade of wind-driven generator includes multiple electrical-heating films 1 and deicing control system
System, the setting of the electrical-heating film 1 correspond to the easy ice forming locations in surface in blade 2, and the electrical-heating film 1 is two layers, each
It is parallel way between electrical-heating film 1, is provided with socket 3 on the wheel hub of the blade 2, socket 3 passes through lead and electrical heating
Film 1 connects, and the electronic lead screw 4 of setting, electronic lead screw 4 are connect by connecting rod 5 with plug 6 in the cabin of wind-driven generator, plug 6
It is connect with deicing control system.
Deicer is described in detail below in conjunction with the accompanying drawings：
As shown in Figure 1, Figure 2, Figure 3 shows, this deicer uses parallel way, in leaf blade manufacture process, by blade
The composite material middle layer of glass fiber reinforcement adds the mode of electrical-heating film material, on blade easily at icing, built-in one
Determine the double-layer electric heating film in parallel of area, if detection has icing, can manually or automatically start deicing control
System synchronization heats ice-melt, and subregion arrangement parallel way can guarantee the minimum influence area in single group failure.Centre increased two
Layer electrical-heating film, is positioned proximate to outer surface, when there is icing, can realize that Discrete control heating is eliminated by tele-control system
Localized ice build excludes quality and security risk that may be present.Electrical-heating film mainly prevents from going out in heater strip production process
Existing frangibility situation, to realize that the heating function service life extends, to improve blade service efficiency.Consider that the work of blade rotation is special
Property, electrical-heating film lead and control system connection type, by way of increasing an electronic lead screw and driving a connector
It realizes, when ice detachment is desired, blade need to be resetted and stop at a specific initial position, make the plug for being fixed on electronic lead screw
It is in aligned position with the socket for being fixed on wheel hub, then electronic lead screw is started by control system, plug is driven to be connected to socket
Together, control system and heating film are connected, realizes computer heating control.As the blade icing detection technique of selection can realize local knot
When ice detects, it can also facilitate and realize the deicing control of blade part.
Manually and automatically two kinds of optional control modes can be used in this clearing ice technology, using existing icing detection technique,
Blade icing decision-making system is constituted by anemobiagraph, temperature sensor, control unit etc., is such as in icing condition, then according to need
Start automatic or manual deice mode（Different patterns can be directly arranged by control system）, realize manually or automatically deicing
Control.
