Abstract

The invention discloses a high-power large-diameter offshore wind generator unit tower frame platform. The high-power large-diameter offshore wind generator unit tower frame platform comprises an outer platform and an inner platform, wherein the outer platform comprises a lower support rod, an upper pull rod, a platform body and a guardrail; the platform body is fixedly connected with a tower cylinder by virtue of the lower support rod and the upper pull rod; an operation platform is arranged above the platform body; a cooling device is arranged between the platform body and the operation platform and is connected with a water cooling pipe which can be led to the inner part of the tower cylinder; the inner platform comprises a transformer platform, a control cabinet platform, a frequency converter platform and a climbing ladder; the transformer platform, the control cabinet platform and the frequency converter platform are designed to be of a three-layer structure; the transformer platform is provided with a transformer platform support which is fixedly connected with the tower cylinder; the transformer platform and the control cabinet platform are fixedly connected through stand columns; the control cabinet platform and the frequency converter platform are fixedly connected through stand columns; the climbing ladder penetrates through the transformer platform, the control cabinet platform and the frequency converter platform.

Description

technical field [0001] The invention relates to a working platform, in particular to a working platform with built-in electrical components in a tower of a high-power offshore wind power generating set and an installation method thereof, belonging to the field of offshore wind power generating equipment. Background technique [0002] The development and utilization of wind energy has a long history. In recent years, offshore wind power generation, as a renewable clean energy, has been highly valued by governments, energy circles and environmental protection circles around the world. In the design of conventional wind turbines, all electrical equipment such as transformers are mostly installed in the tower, which inevitably requires increasing the diameter of the tower. In addition, all electrical equipment is installed on the outer platform, which increases the cost and production difficulty in manufacturing, and increases the difficulty of hoisting at sea, and is not condu...
