Wind power tower drum landing control system

Abstract

The invention relates to a wind power tower drum landing control system which comprises a cover plate, a motor, and a cover plate control machine, wherein the cover plate is arranged on a platform inside a tower drum and is opened upwards for a climbing-free device vehicle body to pass through; the motor drives the cover plate to be opened or closed, and the motor is connected with the cover plate through a rotating assembly; the cover plate control machine comprises a shell and a cavity in the shell, the cavity comprises a semiconductor chilling plate which is controlled by a control circuit board to achieve refrigeration and heating, thecontrol circuit board and an inner cooling fin and an outer cooling fin. The semiconductor chilling plate, the inner cooling fin and the outer cooling fin act together, and the internal environment of the cover plate control machine is maintained at the temperature suitable for working.

Description

technical field [0001] This patent belongs to the field of auxiliary equipment for wind power generating sets, and specifically relates to a control system for a wind power tower tube landing. Background technique [0002] The installed capacity of wind power as the main utilization method of wind energy also maintains a rapid growth rate. In order to obtain more and more stable wind energy in wind power generation, the wind turbine towers are tens or even hundreds of meters high. This makes workers take great risks when installing, overhauling, and maintaining, and their work efficiency is also greatly affected. [0003] The ladder inside the wind turbine tower is equipped with a plurality of platforms, which are arranged at intervals along the height direction of the wind turbine tower, and each platform has a passage for passing through the body of the climbing avoidance device. The opening of the passage And the closure is done by the cover plate. The working range of...

AI Technical Summary

Problems solved by technology

Since the ambient temperature inside the wind power tower can reach over 50°C in summer, coupled with the heat generated by the electronic equipment itself during operation, the ambient temperature of the electronic equipment is much higher than the working temperature range of the automatic cover of the climbing avoidance device, resulting in Increased thermal noise and reduced stability of electronic equipment

In the severe cold in winter in the northern region, some control systems of climbing avoidance devices may fail to start, crash at low temperature, and noise at low temperature due to the influence of low temperature.
