Problems solved by technology

According to the international standard ISO12944-2, the corrosion level of steel structures in the marine environment is C5-M, which is the most corrosive environment and the area with the most severe corrosion, and it is also the focus and difficulty of anti-corrosion protection. Corrosion protection of metal structural hosts poses serious challenges
In addition, once the anti-corrosion coating of offshore wind turbines fails, it is difficult and costly to repair

Embodiment Construction

[0017] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0018] like Figure 1 to Figure 2 As shown, a main engine of a corrosion-resistant wind power generator for offshore use includes a nacelle elbow 1, a generator 2 and a yaw motor 7 are arranged inside the nacelle elbow 1, and a generator casing 21 is provided on the generator 2, and the generator 2 is connected to There is a variable speed gearbox 3, and the variable speed gearbox 3 is connected to a wheel hub 5 through a main shaft bearing 4. The wheel hub 5 is provided with a pitch bearing 6, and the outer surfaces of the main shaft bearing 4 and the pitch bearing 6 are provided with a first anti-corrosion layer. The layers include epoxy zinc-rich primer layer, epoxy mica iron intermediate paint layer, and fluorocarbon topcoat layer from inside to outside. In the first anti-corrosion layer, the thickness of epoxy zinc-rich primer layer is ≥80 ...

Abstract

The invention relates to a host machine for a marine anti-corrosion wind driven generator, which comprises a cabin elbow, wherein a generator, a generator shell, a yaw motor, a speed change gear box, a spindle bearing and a hub are arranged on the cabin elbow; a paddle-changing bearing is arranged on the hub; the host machine is characterized in that first anti-corrosion layers are arranged on the spindle bearing and the paddle-changing bearing; each of the first anti-corrosion layers comprises an epoxy zinc rich primer layer, an epoxy micaceous iron oxide middle painting layer and a fluorocarbon surface painting layer; second anti-corrosion layers are arranged on the generator and the yaw motor; each of the second anti-corrosion layers comprises an epoxy zinc rich primer layer, an epoxy micaceous iron oxide thick-slurry painting layer and a modified polyurethane surface painting layer; third anti-corrosion layers are arranged on the cabin elbow, the speed change gear box, the hub and the generator shell; each of the third anti-corrosion layers comprises an epoxy zinc rich primer layer, an epoxy micaceous iron oxide thick-slurry painting layer and a fluorocarbon surface painting layer; fourth anti-corrosion layers are arranged on the cabin elbow and the interior of the hub; and each of the fourth anti-corrosion layers comprises an epoxy zinc rich primer layer, an epoxy micaceous iron oxide middle painting layer and an improved polyurethane surface painting layer. Different anti-corrosion layers are arranged in different parts of the host machine, so that the anti-corrosion property is increased.

Description

【Technical field】 [0001] The invention relates to a main frame of a wind power generator, in particular to a main frame of a wind power generator used at sea. 【Background technique】 [0002] According to the international standard ISO 12944-1, the life expectancy of the surface anti-corrosion protection of the wind turbine main engine is at least 15 years, and its anti-corrosion protection goal is to meet the life requirements of 30 years in the marine environment. According to the international standard ISO12944-2, the corrosion level of steel structures in the marine environment is C5-M, which is the most corrosive environment and the most corrosive area, and it is also the focus and difficulty of anti-corrosion protection. Corrosion protection of metal structural hosts poses serious challenges. In addition, once the anti-corrosion coating of offshore wind turbines fails, it is difficult and costly to repair. Therefore, it is crucial to design an efficient and durable an...
