Abstract

The invention provides a device for automatically dredging a high-altitude drainage hole of a wind power blade, and belongs to the technical field of wind power. Comprising a fixed seat, a fixed ball head connecting rod, a drain hole supporting ring and two second elastic pieces, a first movable part, a second movable part and a third movable part which are connected with one another are installed in the fixed seat, and the first movable part comprises a movable sleeve connected with the inner side of the fixed seat in a sliding and sleeving mode. By arranging the fixed ball head connecting rod and the second elastic piece, the wind driven generator does not need to be shut down when the drainage hole is dredged, the working time and the working efficiency of the wind driven generator are guaranteed, automatic dredging of the drainage hole is achieved under the condition of no manual operation, the dredging efficiency of the drainage hole is improved, and the working efficiency of the wind driven generator is improved. And the crushing effect on sediments is improved, large sediments are prevented from falling from the high altitude, damage to the outside when the device dredges the drainage hole is avoided, and the safety of the device is improved.

Description

technical field

[0001] The invention relates to the technical field of wind power, in particular to a device for automatically dredging high-altitude drainage holes of wind power blades. Background technique

[0002] The height of the megawatt wind turbine tower is usually 70-80 meters, and with the continuous increase of the single unit capacity, the current domestic wind turbine tower is about 150 meters high. Most of the operation and maintenance work after the installation of wind turbine blades needs to be carried out by means of climbing outside the tower. The climbing operation at such a height has very high requirements on the quality of operation equipment, operators, technology and safety protection. The most important tower The risk of manual work at heights outside the cylinder is extremely high. When the temperature difference between day and night is large, condensed water will be generated in the cavity of the wind turbine blade, and the condensed water will ...
