DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0018] An oil adsorption device for a wind turbine, comprising an upper net cover 1 and a lower net cover 2. The upper net cover 1 and the lower net cover 2 are hollow inside. An adsorption layer 3 is arranged inside the upper net cover 1 and the lower net cover 2. The adsorption layer 3 is diatomite or perlite powder. At both ends of the lower part of the upper net cover 1 and at both ends of the top of the lower net cover 2, a first fixing ear 4 is respectively arranged. Two first fixing ears 4 at the same end are fixedly connected by a first bolt 5. Both sides of the bottom of the lower net cover 2 are respectively fixedly connected to the top ends of a vertical rod 6. The bottom of the vertical rod 6 is fixedly connected to the top surface of a bottom plate 7. A fixing device is arranged on the bottom surface of the bottom plate 7. In the utility model, the splashed lubricating oil can be conveniently absorbed by the adsorption layer 3. At the same time, the upper net cover 1 and the lower net cover 2 can be conveniently assembled and separated, which is convenient for replacing the adsorption layer 3 after saturation and for subsequent lubricating oil addition operation at the rotating shaft or bearing of the wind turbine. At the same time, the fixing device can increase the stability of the bottom plate 7 during use and ensure its long-term stable use.

[0019] Specifically, since the lubricating oil may splash out from both ends of the upper net cover 1 and the lower net cover 2, in order to overcome the above problems, in this embodiment, both ends of the upper net cover 1 and the lower net cover 2 are respectively fixedly connected to one side of an oil-proof cloth 8. The oil-proof cloth 8 is fixedly connected to a semi-circular ring 9 on the side far from the upper net cover 1 and the lower net cover 2. At both ends of the same-side semi-circular ring 9, a second fixing ear 10 is respectively arranged. The second fixing ears 10 on the same side can be fixed by a second bolt 11. A multi-stage telescopic rod 12 is arranged between the semi-circular ring 9 and the top end of the corresponding side of the upper net cover 1 or the bottom of the lower net cover 2. Both ends of the multi-stage telescopic rod 12 are respectively rotatably connected to the semi-circular ring 9 and the top end of the corresponding side of the upper net cover 1 or the bottom of the lower net cover 2 through a universal ball joint 13. The oil-proof cloth 8 is arranged at both ends of the upper net cover 1 and the lower net cover 2, and is fixed to the non-rotating parts through two semi-circular rings 9. At the same time, the multi-stage telescopic rod 12 can support the oil-proof cloth 8 to prevent the lubricating oil from splashing out from both ends of the upper net cover 1 and the lower net cover 2.

[0020] Specifically, in this embodiment, the adjacent parts of the two oil-proof cloths 8 on the same side can be fixedly connected by a magic tape 14. Through the magic tape 14, the gaps between the two oil-proof cloths 8 on the same side can be fixed, further reducing the possibility of lubricating oil splashing out.

[0021] More specifically, the fixing device in this embodiment is a magnetic plate 15 or several suction cups 16. When the placement surface is made of steel, the magnetic plate 15 is used. When the material cannot be magnetically fixed, the suction cups 16 are used.

[0022] Furthermore, a handle 17 is arranged at the central position of the top of the bottom plate 7 in this embodiment. Through the handle 17, the bottom plate 7 can be conveniently picked up for use.

[0023] Furthermore, the vertical rod 6 described in this embodiment is a telescopic rod structure. The telescopic rod structure of the vertical rod 6 facilitates adjustment for use at different heights.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
