Wind-driven generator electrothermal ice melting rotor blade, electrothermal chip and forming device and method

Abstract

The invention provides a wind-driven generator electrothermal ice melting rotor blade, an electrothermal chip and a forming device and a method. The electrothermal chip comprises glass fiber cloth, and a carbon fiber bundle is sewn on the glass fiber cloth. The forming device comprises a forming machine, a feeding support arranged in front of the forming machine, and a heating device and a material receiving device sequentially arranged behind the forming machine, wherein a plurality of rolling?shafts are arranged on the feeding support; and the?rolling?shafts are winded with?carbon fiber. As the carbon fiber bundle is sewn on the glass fiber cloth by the forming machine, the manufacturing technology is simple and integration is high; as the electrothermal chip is composed of glass fiber cloth and carbon fiber and free of metal, material demands of the rotor blade can be met; and the glass fiber cloth is high in permeability, the electrothermal chip is poured in the rotor blade, the pouring technology demand of the rotor blade can be met, the manufactured electrothermal ice melting rotor blade can use thermal energy generated after the carbon fiber is electrified, and the rotor blade can be prevented from being frozen.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to an electric heating ice-melting rotor blade of a wind power generator, an electric heating chip, a forming device and a forming method thereof. Background technique [0002] Wind power generation is a new energy widely used at home and abroad. However, due to climate change, especially in recent years, the increase of freezing rain in my country has caused serious harm. Wind turbines cause great harm. [0003] At present, the method usually used to eliminate the icing on the rotor blades is: when the rotor blades are icing to a certain extent, stop the machine for deicing. The deicing method is to wait for the temperature to rise and deicing naturally, and the second is to manually beat the icing. The above methods exist The following disadvantages: affect the power generation of the generator set; knocking will cause damage to the generator set. [0004] Chinese i...

[0002] Wind power generation is a new energy widely used at home and abroad. However, due to climate change, especially in recent years, the increase of freezing rain in my country has caused serious harm. Wind turbines cause great harm

[0003] At present, the method usually used to eliminate the icing on the rotor blades is: when the rotor blades are icing to a certain extent, stop the machine for deicing. The deicing method is to wait for the temperature to rise and deicing naturally, and the second is to manually beat the icing. The above methods exist The following disadvantages: affect the power generation of the generator set; knocking will cause damage to the generator set

[0004] Chinese invention patent 200810049360.5 discloses an automatic auxiliary electrothermal ice-melting device for high-voltage electric towers. In a long shell made of right-angled two panels, a bottom plate and two end covers, an electric heating core and insulating filler are placed longitudinally in the cavity, and the shell The cross section of the body is a right triangle; the electric heating core is placed in the upper part of the shell cavity, and the insulating filler is placed in the lower part of the shell. The heating power of the electric heating core is 50-200W / m. , whose two ends are drawn from the same end; the high-voltage electric tower automatic auxiliary electric heating ice-melting device is installed on the high-voltage electric tower body, which can prevent the surface of the high-voltage electric tower from icing and the device that melts ice at any time after freezing, forming The electrothermal ice-melting technology applied to high-voltage electric towers, but this technology cannot be directly applied to the rotor blades of wind turbines.
