Row is installed.Permanent magnet linear generator is fixed at the trailing edge of blade body 100 in 102 blade girder.Permanent-magnet linear
Generator can also use other structures form using cylinder-like structure, when blade body 100 carries out heating deicing, move
Son 31 does straight reciprocating motion between the end 322 of first end 321 and second relative to support 320.Permanent magnet linear generator is installed
When, first end 321 is towards the direction of blade tip 103, and the second end 322 is towards the direction of blade root 105.
As optional example, spontaneous electrical heating deicer 1 further comprises electromagnetic and mechanical mechanism 80, is arranged at permanent magnetism
Second end 322 of linear electric generator support 320, the mover 31 for discharging or braking permanent magnet linear generator, in original state
Lower electromagnetic and mechanical mechanism 80 clamps the second end 322 that mover 31 is fixed on permanent magnet linear generator support 320.
As optional example, heating control apparatus 50 can be arranged at the blade root 105 of each blade body 100.
As optional example, temperature monitoring 70 can be temperature sensor.
As shown in fig. 6, being respectively mounted spontaneous electrical heating deicer 1 in each blade body of wind-driven generator.Wind
Power generator control system 500 is removed by slip ring 600, signal/service cable 90 and the spontaneous electrical heating in every blade body
Ice production apparatus 1 is connected.
When icing detector 400 detects a certain of wind-driven generator or certain several blade body outer surface has begun to knot
After ice, the icing signal such as direct current 24V voltage signals is sent to wind power generator control system 500, wind-driven generator control
System 500, which is received, judges which blade body of wind-driven generator is in after freezing environment after signal, pass through slip ring 600
And signal/service cable 90 sends the computer heating control that direct current 24V voltage signals are set to the blade root 105 of correspondence blade body
Device 50, receives the heating control apparatus 50 of icing signal to the permanent magnet linear generator support 320 set in blade body
The electromagnetic and mechanical mechanism 80 set at second end 322 sends direct current 24V voltage signals, also referring to Fig. 4 a and Fig. 4 b, electromagnetism
Coil 85, which is received, produces magnetic field after electric signal, under magnetic force, and four clamping plates 83 overcome the pressure of spring 82 to away from the center of circle
Direction is moved, and now the mover 31 of magneto 30 is no longer influenced by the clamping of the clamping plate 83 of electromagnetic and mechanical mechanism 80 and is released.
After mover 31 is released, constantly change with the rotation of impeller and the position of blade body of wind-driven generator, permanent-magnet linear
The mover 31 of generator can carry out straight reciprocating motion, the coil of stator 32 of permanent magnet linear generator in the presence of self gravitation
It is upper generation electric energy and the electric heating film 10 to blade body outer surface power, obtain electric energy electric heating film 10 start heating heating
The significant points of blade body edge 101.In the impeller rotary course of wind-driven generator, the electric energy of permanent magnet linear generator
Source is constantly conveyed to electric heating film 10, when the temperature of blade body outer surface reaches more than 0 DEG C, and ice sheet starts to melt, ice
Adhesive force of the layer in blade body declines.When the adhesive force of ice sheet declines to a certain extent, with the motion of blade body
Ice sheet will depart from blade body, and the ground landed, and so spontaneous electrical heating deicer 1 has just reached the effect of deicing
Really.
Operation in order to ensure blade prevents safely blade body 100 due to the too high initiation blade of the temperature of electric heater unit 10
Body 100 is damaged or caught fire, while permanent magnet linear generator operation is heated to blade body 100, blade body 100
The heating control apparatus 50 of interior setting receives the monitoring signals from the temperature monitoring 70 for being embedded in blade body 100, to leaf
The heating-up temperature of piece body 100 is monitored.The temperature that temperature monitoring 70 is monitored exceedes the default temperature value such as 15 DEG C
When, heating control apparatus 50 controls to set at the second end 322 of the permanent magnet linear generator support 320 in blade body 100 respectively
The electromagnetic and mechanical mechanism 80 put catches mover 31, stops the generator operation of permanent magnet linear generator, therefore by the above method to leaf
The heating-up temperature of piece body 100 sets upscale protection.In order to ensure that the operation of blade prevents safely temperature monitoring 70 not normal to leaf
The heating-up temperature monitors failure of piece body 100 can further set supervising device (not shown) or temperature monitoring protection device
(not shown) etc., by the state real-time report of temperature monitoring 70 to heating control apparatus 50, heating control apparatus 50 is controlled respectively
The electromagnetic and mechanical mechanism 80 set at second end 322 of the permanent magnet linear generator support 320 in blade body 100 catches mover
31, stop the generator operation of permanent magnet linear generator.
It is specific that whether the temperature monitoring method of blade body 100 and the spontaneous electrical heating deicer 1 of control are continued to run with
Method it is as follows, whether heating control apparatus 50 first determines whether the temperature of blade body 100 in the default temperature model such as 15 DEG C
Within enclosing, judged result is not within the scope of default, then heating control apparatus 50 controls electromagnetic and mechanical mechanism 80, by electromagnetic motor
Tool mechanism 80 catches or forbids discharging mover 31, and judged result continues to judge the temperature between blade within the scope of default, then
Difference is spent whether within preset range, and judged result is not within the scope of default, the temperature of such as first blade body 100
Spend for 14 DEG C, the temperature of second blade body 100 is 0 DEG C, and the temperature of the 3rd blade body 100 is minus 16 DEG C, then by electricity
Magnetic mechanical mechanism 80 catches or forbids discharging mover 31, and judged result sees that whether receiving icing visits within the scope of default, then
The icing information that device 400 is sent is surveyed, judged result is otherwise to be caught by electromagnetic and mechanical mechanism 80 or forbid discharging mover 31, if
Judged result is yes, then instructs electromagnetic and mechanical mechanism 80 to discharge mover 31, run permanent magnet linear generator.It may be appreciated
It is that heating control apparatus 50 can also judge whether electric heater unit 50 is in maintenance/maintenance situation, if it is judged that being
It is then to send maintenance/maintenance signal to wind power generator control system 500, while heating control apparatus 50 controls electromagnetic and mechanical
Mechanism 80, is caught by electromagnetic and mechanical mechanism 80 or forbids discharging mover 31.
