[0027] Refer to Figures 1-4 As shown in the figure, this embodiment discloses a blade de-icing device, which includes an outer shell 1. A fan 4 is arranged inside the outer shell 1, an electric heating wire 5 is arranged inside the outer shell 1, and an auxiliary device 2 is arranged on one side of the outer shell 1.

[0028] Refer to Figures 1-4 As shown in the figure, this embodiment discloses that the auxiliary device 2 includes a first bolt 21. The first bolt 21 is threadedly connected to the outer shell 1. An extension pipe 22 is threadedly connected to one side of the first bolt 21. A placing block 23 is fixedly connected to one side of the outer shell 1. An adjusting plate 24 is slidably connected to one side of the placing block 23. A support frame 25 is fixedly connected to one side of the adjusting plate 24. One side of the support frame 25 is sleeved on one side of the extension pipe 22. A clamping block 26 is inserted into one side of the placing block 23. A plurality of card slots 27 are formed on one side of the adjusting plate 24. The clamping block 26 is clamped with the card slot 27 on one side of the adjusting plate 24. When the surface of the blade of the fan 4 generator freezes, hot air will be blown out through the fan 4 on one side of the outer shell 1 and the electric heating wire 5 inside the outer shell 1, so that the hot air reaches the inner cavity of the blade, and then the temperature of the blade is increased to melt the ice on the blade, completing the ice breaking of the blade. After installing the outer shell 1 inside the blade, the extension pipe 22 with a suitable size can be prepared according to the blade size, and then the extension pipe 22 is fixed to the outer shell 1 through the first bolt 21. Then the support frame 25 is moved so that one side of the support frame 25 is sleeved on the extension pipe 22 to support the extension pipe 22. At this time, the support frame 25 drives the adjusting plate 24 to move inside the placing block 23. Then after the support frame 25 is in a suitable position, the clamping block 26 is moved so that the clamping block 26 passes through the placing block 23 and is clamped with the card slot 27 on one side of the adjusting plate 24 to complete the fixation of the position of the support frame 25. By using the auxiliary device 2, the hot air blown out by the cooperation of the fan 4 and the electric heating wire 5 can be guided to the place near the tail wing of the blade, and then the situation that the temperature drops too much when the hot air reaches the tail wing from inside the blade, affecting the de-icing effect of the blade tail wing, can be avoided, thereby improving the use effect of the blade de-icing device.

[0029] Refer to Figures 1-4As shown in the figure, in this embodiment, a magnet 28 is fixedly connected to one side of the placement block 23, and an iron block 29 is fixedly connected to one side of the clamping block 26. The iron block 29 and the magnet 28 are magnetically attracted to each other. The magnet 28 adsorbs the iron block 29 on the clamping block 26, making it difficult for the clamping block 26 to disengage from the card slot 27 on one side of the adjustment plate 24, thereby improving the use effect of the clamping block 26. A connecting rope 210 is fixedly connected to one side of the clamping block 26, and the side of the connecting rope 210 away from the clamping block 26 is fixedly connected to the adjustment plate 24. By using the connecting rope 210, the clamping block 26 is connected to the placement block 23 to prevent the loss of the clamping block 26, thereby improving the use effect of the clamping block 26. A plurality of anti-slip blocks 211 are fixedly connected to one side of the support frame 25, and the plurality of anti-slip blocks 211 are arranged at equal intervals on one side of the support frame 25. By using the anti-slip blocks 211, the friction between the support frame 25 and the operator is increased, making it easier for the operator to move the adjustment plate 24 through the support frame 25.

[0030] Referring to Figures 1-4 As shown in the figure, in this embodiment, a heat preservation component 3 is provided on one side of the extension pipe 22. The heat preservation component 3 includes a fixing plate 31. One side of the fixing plate 31 is fixedly connected to the extension pipe 22. A second bolt 32 is threadedly inserted into one side of the fixing plate 31. One side of the second bolt 32 is threadedly connected to a rock wool heat preservation sleeve 33. The rock wool heat preservation sleeve 33 is adapted to the size of the extension pipe 22. When using the extension pipe 22, the rock wool heat preservation sleeve 33 can be sleeved on the extension pipe 22, and then the second bolt 32 is rotated to make the second bolt 32 pass through the fixing plate 31 and fix the rock wool heat preservation sleeve 33. Then the rock wool heat preservation sleeve 33 insulates the extension pipe 22. By using the heat preservation component 3, the heat of the hot air conveyed by the extension pipe 22 is not easily dissipated, so that the hot air can better reach the blade tail wing, thereby improving the use effect of the auxiliary device 2.

[0031] Referring to Figures 1-4 As shown in the figure, in this embodiment, a gasket 34 abuts against one side of the second bolt 32, and one side of the gasket 34 abuts against the fixing plate 31. By using the gasket 34, the friction between the second bolt 32 and the fixing plate 31 is increased, making the second bolt 32 fix the rock wool heat preservation sleeve 33 more firmly. A positioning block 35 is fixedly connected to one side of the fixing plate 31. The positioning block 35 is adapted to the size of the card slot 27 of the rock wool heat preservation sleeve 33. By using the positioning block 35, the rock wool heat preservation sleeve 33 is quickly positioned at the position of the extension pipe 22, so that the rock wool heat preservation sleeve 33 no longer rotates, and then it is convenient to use the second bolt 32 to fix the rock wool heat preservation sleeve 33 subsequently.

[0032] Working principle: When ice forms on the surface of the blades of the fan 4 generator, hot air is blown through the fan 4 on one side of the housing 1 and the heating wire 5 inside the housing 1, so that the hot air reaches the inner cavity of the blades, and then the temperature of the blades is increased to melt the ice on the blades, completing the ice breaking of the blades. After installing the housing 1 inside the blade, the extension pipe 22 with a suitable size can be prepared according to the blade size, and then the extension pipe 22 is fixed to the housing 1 through the first bolt 21. Then, the support frame 25 is moved so that one side of the support frame 25 is sleeved on the extension pipe 22 to support the extension pipe 22. At this time, the support frame 25 drives the adjusting plate 24 to move inside the placing block 23. Then, after the support frame 25 is in a suitable position, the clamping block 26 is moved so that the clamping block 26 passes through the placing block 23 and is clamped and fixed to the clamping groove 27 on one side of the adjusting plate 24. At this time, the iron block 29 on the clamping block 26 is adsorbed by the magnet 28, so that the clamping block 26 is not easily separated from the clamping groove 27 on one side of the adjusting plate 24, and then the position of the support frame 25 is fixed. By using the auxiliary device 2, the hot air blown out by the cooperation of the fan 4 and the heating wire 5 can be guided to the place near the tail wing of the blade, and then the situation that the temperature drops too much when the hot air reaches the tail wing from inside the blade, affecting the ice removal effect at the tail wing of the blade, can be avoided, thereby improving the use effect of the blade ice removal device.

[0033] When using the extension pipe 22, the rock wool heat insulation sleeve 33 can be sleeved on the extension pipe 22, and then the second bolt 32 is rotated so that the second bolt 32 passes through the fixing plate 31 and is fixed to the rock wool heat insulation sleeve 33. Then, the rock wool heat insulation sleeve 33 insulates the extension pipe 22. By using the heat insulation component 3, the heat of the hot air conveyed by the extension pipe 22 is not easily dissipated, so that the hot air can better reach the tail wing of the blade, thereby improving the use effect of the auxiliary device 2.
