Problems solved by technology

[0002] Offshore wind turbines are used to operate on the sea, generate electricity through wind power, and then store the electricity. However, the offshore wind turbines in the prior art still have some disadvantages in actual use, such as poor corrosion resistance, due to seawater And the corrosive effect of the air will seriously shorten the service life of the generator set

Embodiment 1

[0022] The present invention provides such as Figure 1-3 The anti-corrosion offshore wind turbine shown includes a bearing platform 1, the bottom of the bearing platform 1 is fixed with an underwater bottom pile 2 and the side is fixed with an underwater side pile 3, the bearing platform 1, the underwater bottom Both the outside of the pile 2 and the underwater side pile 3 are provided with a pickling passivation layer 4, the outside of the pickling passivation layer 4 is provided with a first corrosion-resistant paint layer 19, and the top of the bearing platform 1 is fixed with a base 5 and An accommodating chamber 6, the accommodating chamber 6 is arranged on the outside of the base 5, the top of the base 5 is fixed with a vertical beam 7, the inside of the vertical beam 7 is provided with a generator 8, and the generator 8 is provided with a transmission shaft 9 A fan blade 10 is sleeved on the outside of the transmission shaft 9 , and a second corrosion-resistant paint l...

Embodiment 2

[0032] An anti-corrosion method for an anti-corrosion offshore wind turbine, including the anti-corrosion offshore wind turbine, further comprising the following steps:

[0033] S1: the oil supply pipe 13 and the oil tank 15 input the setting parameters into the main control unit 18;

[0034] S2: the main control unit 18 timing control relay 17 is opened;

[0035] S3: the power storage unit 16 energizes the booster pump 14;

[0036] S4: the booster pump 14 after energization sends the lubricating oil in the oil tank 15 into the funnel 12 through the oil supply pipe 13;

[0037] S5: The lubricating oil falls from the funnel 12 to the connection between the vertical beam 7 and the transmission shaft 9, which can form an oil film while lubricating, thereby avoiding the contact between the air and the transmission shaft 9.

Abstract

The invention discloses a corrosion-resistant offshore wind turbine generator system and a corrosion-resistant method. The wind turbine generator system comprises a bearing platform of which the bottom is fixedly provided with an underwater bottom pile, and the sides of the bearing platform are fixedly provided with underwater side piles; the bearing platform, the underwater bottom pile and the underwater side piles are each provided with a pickling and passivating layer of which the outer side is provided with a first corrosion-resistant coating; the top of the bearing platform is fixedly provided with a base and a containing chamber arranged on the outer side of the base, and the top of the base is fixedly provided with a vertical beam which is internally provided with a generator; and the generator is provided with a transmission shaft of which the outer side is provided with fan blades in a dowel joint manner, and the outer sides of the vertical beam, the transmission shaft and thefan blades are each provided with a second corrosion-resistant coating. According to the wind turbine generator system, the effective corrosion protection of parts and components is achieved, and theparts and the components are prevented from being corroded by seawater and air, so that the service life of the wind turbine generator system is prolonged effectively, and the wind turbine generatorsystem is rational in design, and higher in practicability.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to an anti-corrosion offshore wind turbine and an anti-corrosion method. Background technique [0002] Offshore wind turbines are used to operate on the sea, generate electricity through wind power, and then store the electricity. However, the offshore wind turbines in the prior art still have some disadvantages in actual use, such as poor corrosion resistance, due to seawater As well as the corrosive effect of the air, it will seriously shorten the service life of the generator set. [0003] Therefore, it is necessary to invent an anti-corrosion offshore wind turbine and an anti-corrosion method to solve the above problems. Contents of the invention [0004] The object of the present invention is to provide an anti-corrosion offshore wind turbine and an anti-corrosion method, using the pickling passivation layer, the first corrosion-resistant paint layer and the se...
