wind turbine nacelle

Abstract

The invention discloses an automatic door which comprises a frame and a body matched with the frame. The body is movably hinged to the frame, and the body can rotate relative to the frame. The automatic door further comprises an automatic door opening and closing mechanism. The automatic door opening and closing mechanism comprises a pulley assembly arranged on the inner wall of the body, a supporting rod connected with the pulley assembly, a rotating shaft for fixing the supporting rod, a fixing part for fixing the rotating shaft and a power part for rotating the rotating shaft, wherein the fixing part and the power part of the rotating shaft are arranged on the inner side of the frame. The invention further discloses a wind driven generator cabin cover with the automatic door. According to the automatic door and the wind driven generator cabin cover with the automatic door, the automatic door opening and closing mechanism is adopted to achieve full-automatic opening and closing of the door. The automatic door of the wind driven generator cabin cover serves as a big opening in the top of the wind driven generator cabin cover, so that replacement of big parts in the wind driven generator cabin cover is facilitated, and unsafe operation of manually pushing and pulling the door is avoided.

Description

technical field [0001] The invention relates to the technical field of doors, in particular to an automatic door and a wind turbine nacelle cover including the automatic door. Background technique [0002] At this stage, with the continuous development of science and technology, automatic doors are more and more widely used in people's lives, especially for large factories and large equipment. In the field of wind power generators, with the extension of the running time of wind turbines, some large parts in the nacelle cover are prone to failure, such as bearings, gearboxes, generators, etc. The top opening of the existing wind turbine nacelle cover is small, which can only be used by maintenance personnel to enter and exit and replace small parts of the unit, but it involves the maintenance and replacement of large parts with high failure rates such as bearings, gearboxes, and generators. It is more difficult, and the upper cover must be removed or the whole machine must b...

AI Technical Summary

Problems solved by technology

The top opening of the existing wind turbine nacelle cover is small, which can only be used by maintenance personnel to enter and exit and replace small parts of the unit, but it involves the maintenance and replacement of large parts with high failure rates such as bearings, gearboxes, and generators. It is more difficult. It is necessary to remove the upper cover or hoist the whole machine to the ground for replacement, resulting in high maintenance costs, long periods, and great difficulty, which seriously affects the operation of the unit and causes huge economic losses.

Moreover, the current hole cover structure of the top opening of the wind turbine cabin cover is a sliding door structure, which needs to be manually pushed and pulled, which is dangerous to a certain extent.

Nowadays, the nacelle of offshore wind turbines is developing day by day, and it is more difficult to maintain and replace some large parts of offshore wind turbines.

[0003] It can be seen that the above-mentioned existing wind turbine nacelle cover top opening is small and the hole cover is a sliding door structure. In terms of structure, method and use, there are obviously still inconveniences and defects, and it is urgent to be further improved.
