The invention discloses a CNJT adjustable speed safe intelligent high-power vertical axis windmill sail, which is a brand new reform of a working principle and a structure of the conventional vertical axis windmill, and overcomes the problems of no moment, low efficiency and difficult speed control at over speed of the conventional vertical axis windmill blade and low wind power utilization efficiency of the current widely applied horizontal axis windmill. The new technical scheme of CNJT is as follows: the CNJT adjustable speed safe intelligent high-power vertical axis windmill sail comprises multiple compounded motion intelligent blades, the working moment is obtained through a technical scheme capable of reducing the areas of the blades incapable of working, and the wind power utilization efficiency is greatly improved. When a storm comes, by applying a principle of reducing the working area of the working movable blades of the windmill, wind loads of the blades on the both sides are removed, and safety of the windmill rail is ensured. The CNJT adjustable speed safe intelligent high-power vertical axis windmill sail has the following innovations that: the wind power utilization efficiency is higher than a horizontal axis windmill. Through increasing the blade groups, the total power of the single windmill is increased. Without a wind alignment device, the CNJT adjustable speed safe intelligent high-power vertical axis windmill sail is suitable for power generation of marine wind power, platforms and ships, and power of marine ship rails. Through speed regulation or halt of the intelligent blades, safety of the windmill rail is ensured.
