A method for preparing a carbon nanotube-graphene composite anti-icing and deicing system for wind power blades

Abstract

The invention provides a carbon nanotube-graphene composite anti-icing and deicing system for wind power blades, including a temperature monitoring system, a composite heating film system, an overall temperature control system and a circuit system. The temperature monitoring system is distributed in different parts of the blade, which can accurately monitor the real-time temperature of each part of the blade. The composite heating film system is distributed in different parts of the blade corresponding to the temperature monitoring system and heats the blade. The overall temperature control system is connected with the composite heating film system through the circuit system. The temperature monitoring system is respectively connected to the composite heating film system and the overall temperature control system, which can monitor the temperature of each part of the blade in real time, maintain the overall temperature of the blade at 2 °C through the temperature control system, and can heat the lower part of the blade separately. . This system is lightweight, low cost, high de-icing efficiency, low energy consumption, and has excellent anti-icing and de-icing capabilities in the application.

Description

Preparation of a carbon nanotube-graphene composite anti-icing and deicing system for wind power blades method technical field The present invention relates to a kind of preparation method of the carbon nanotube-graphene composite anti-icing and deicing system of wind power blade, belongs to In the field of wind power auxiliary equipment. Background technique [0002] When the wind turbine is operating in the air temperature below freezing point, freezing phenomenon may occur. After the leaves are iced The added weight has a large impact on the mechanical properties of the wind turbine, especially the ice load that can be loaded on each blade Different, the unbalanced load that leads to the operation of the unit increases, which will cause great harm to the unit, especially those built in the high cold. In order to prevent the damage of the wind turbines, the wind power generation installations in the region sometimes have to be shut down, and the utilization rate o...

Problems solved by technology

Using the rotating motion of the fan to make the permanent magnet generator generate electricity and use it as the power supply of the electric heating device to achieve the effect of "self-heating". A good solution, ordinary electric heating devices have slow heating speed and high energy consumption, so they cannot be widely used on fan blades
