Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0013] Such as figure 1 , figure 2 As shown, the present invention is installed on the side wall of the generator cabin 7, including an axial fan 1, a support frame 2, a salt spray filter layer 3, a dehumidification filter layer 4, an upper bracket 5, and a lower bracket 6.

[0014] Wherein, the axial flow fan 1 has an air cylinder 11, the bottom end of the air cylinder 11 is fixedly connected to the side wall of the generator cabin 7 with bolts, and the bottom end of the air cylinder 11 corresponds to the side wall of the generator cabin 7 as an open end.

[0015] The support frame 2 is a cylindrical structure whose size matches the top of the fan cylinder 11 of the axial flow fan 1. The top and bottom ends of the support frame 2 are provided with outwardly protruding side edges, and the sides of the bottom end of the support frame 2 use bolts. I...

Abstract

The invention relates to a salt fog resistant system for a wind generating set at sea, which is characterized by comprising an axial flow fan, a supporting frame, a salt fog filter layer, a dehumidification filter layer, an upper bracket and a lower bracket, wherein, the bottom end of the blow dryer of the axial flow fan is fixedly connected on the side wall of a cabin of a generator, the bottom end of the supporting frame is tightly fixed on the top end of the blow dryer of the axial flow fan, the upper bracket and the lower bracket are both fixedly connected on the top end of the supporting frame, and the salt fog filter layer and the dehumidification filter layer respectively cover on the top part of the supporting frame with the support of the upper bracket and the lower bracket. The invention also comprises two contact sealing rings which are respectively installed at the joint of the cabin of the generator and a hub and the joint of the cabin of the wind generating set and a tower drum. The invention can be widely applied to the salt fog resistant operation of the wind generating set at sea.

Description

technical field [0001] The invention relates to an anti-salt spray system, in particular to an anti-salt spray system for an offshore wind power generating set. Background technique [0002] Due to the extremely high humidity and salinity of the sea air, the air is very erosive to offshore wind turbines. The existing anti-salt spray corrosion measures for offshore wind turbines mainly include: painting mechanical parts, sealing electronic devices and installing sealing brushes, but the effects of these sealing measures are not very satisfactory. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a salt spray protection system for offshore wind power generators that is easy to install and use, and has a good salt spray prevention effect. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: an offshore wind turbine salt spray protection system, characte...
