Problems solved by technology

However, such a technical solution is still relatively complicated, and the material of the blade is not a good conductor of heat. Heating from the hollow inner cavity will greatly affect the heating efficiency of the blade surface. If the heating temperature is too high, it will greatly affect the thermal deformation temperature of the resin used in the blade. High requirements and may bring new problems, so it is difficult to promote in practical applications

Embodiment 1

[0032] An anti-icing wind turbine blade, including a heating system, a control system, a power supply and a blade 1; the control system controls the power supply to be turned on and off; it is characterized in that: the heating system mainly includes a conductor 2 on the blade and heating coating 4; the blade 1 is covered with an insulating layer, the conductor 2 is arranged on the insulating layer, the heating coating 4 is covered on the conductor and the insulating layer, and the surface of the heating coating 4 is insulated layer coverage.

[0033] In practical application, when an ice layer appears on the surface of the blade 1 or the temperature is too low and needs to be heated, the control system controls the power to be turned on, the conductor 2 is energized, and the current is conducted to the heating coating 4, and the heating coating 4 starts to generate heat, and the surface temperature of the blade 1 It rises to melt the ice layer, and through the control of the ...

Embodiment 2

[0035] An anti-icing wind turbine blade, including a heating system, a control system, a power supply and a blade 1; the control system controls the power supply to be turned on and off; it is characterized in that: the heating system mainly includes a conductor 2 on the blade and heating coating 4; the blade 1 is covered with an insulating layer, the conductor 2 is arranged on the insulating layer, the heating coating 4 is covered on the conductor and the insulating layer, and the surface of the heating coating 4 is insulated layer coverage.

[0036] The heating system is more than one group, connected in parallel.

[0037] The heating system also includes a conductive medium layer 3, which covers the conductor and is located under the heating coating 4, increasing the stability and contact area between the heating coating 4 and the conductive medium. The conductor is copper foil, which further reduces the weight increase and does not cause changes to the shape of the blade....

Embodiment 3

[0042] A method for preparing an anti-icing wind turbine blade, comprising the following steps:

[0043] 1) Preparatory work: hang the blade 1 to the predetermined position, and modify and polish the surface of the blade;

[0044] 2) Coating process: first coat the insulating layer on the surface of the blade 1, then paste the conductor 2 on the blade 1, coat the conductive medium layer 3 on the conductor 2, and coat the heat-generating coating on the conductive medium layer 3 4. Finally, an insulating layer is applied to the surface of the blade 1;

[0045] 3) Improvement work: repair and polish the above-mentioned blades after coating the insulating layer, and then apply a protective coating to blade 1;

[0046] 4) Installation test: After connecting the main wires in parallel, hoist the above-mentioned painted blades, install the rotating power connection device, connect the control system, connect the power supply, and conduct the test.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to preparing a blade of a wind power generator. Background technique [0002] With the outbreak of energy crises again and again, and the reserves of oil resources are not unlimited, there are not many reserves that can be exploited and utilized at present. Therefore, people must estimate the possible crisis caused by the depletion of mineral energy resources and explore them as soon as possible. , Research, development and utilization of new energy sources. With the occurrence of the Chernobyl accident and the nuclear leak of the Fukushima nuclear power plant in Japan, people are increasingly looking for safe and green new energy. [0003] Wind power is a new energy source with great potential. It has been estimated that there are about 10 billion kilowatts of wind power resources on the earth that can be used to generate electricity, which is almost 10 times the cur...
