Extravehicular overhauling protection method and device for wind generating set

Abstract

The invention discloses an extravehicular overhauling protection method and an extravehicular overhauling protection device for a wind generating set. A protective operation device is fixed on a cabin cover by using the cabin cover and cabin cover reserved holes, the protective operation device is divided into an upper bracket and a lower bracket, the upper bracket is placed above the upper cabincover, the lower bracket is placed below the upper cabin cover, and the upper bracket and the lower bracket pass through the cabin cover reserved holes and are connected through connectors; the lower bracket is provided with a clamping device, and the protective operation device is fixed on the cabin cover by the clamping device; the upper bracket is provided with a guardrail port, and a guardrail is arranged on the guardrail port; and the proper guardrail is selected according to the extravehicular working contents, and the guardrail is arranged on the guardrail port of the upper bracket to form a protective operation platform so as to provide effective operation protection for extravehicular overhauling operation of workers. Moreover, the device can be expanded into a multifunctional overhauling platform by increasing a corresponding tool box or pendant on the guardrail.

Description

technical field [0001] The invention relates to a maintenance method and device for wind power generation equipment, in particular to a method and device for protecting components such as a rainproof cover for maintenance of blades outside a nacelle of a megawatt-class wind power generation unit. It is mainly used for inspection and maintenance of the components on the top of the wind turbine nacelle in the air. Background technique [0002] The nacelle and wind rotor of the wind turbine are usually installed on a tower with a height of tens of meters to hundreds of meters. Most of the inspection and maintenance work of the unit is carried out inside the nacelle or the hub, but there are also some important parts outside the nacelle, such as blades for rain protection. Covers, lightning rods, heat dissipation ducts, anemometers, aviation lights, radiators, etc. When overhauling parts outside the nacelle, it is necessary for the staff to reach the outside of the nacelle thro...

AI Technical Summary

Problems solved by technology

When the staff reaches the top of the cabin, if they stand and work, due to the high center of gravity of the body, if there are no guardrails on both sides, it will be very dangerous, and the psychological pressure of the staff will be great, which is not conducive to the work.

If you work in a squatting or sitting position, without armrests, the range of motion and operation will be limited due to the lack of protection for the upper body
