Embodiment 1

[0165] Depend on figure 1 Shown is a schematic diagram of a CNJT adjustable-speed safe intelligent high-power vertical-axis windmill sail of the present invention. The windmill frame 1 and the flexible blade 2 are made of flexible materials, and the design and layout of the flexible blade 2 is composed of multiple polygons to form a window that can only pass through the airflow in one direction. The non-working flexible blade 2 on the other side can automatically allow the airflow to pass through under the action of wind force, so that the cross-sectional area of ​​the flexible blade 2 is reduced into a linear shape, and the work torque is obtained; The technical scheme, so that the flexible blade 2 rolls up, the airflow will pass through the windmill frame 1, such as figure 2 .

Embodiment 2

[0167] Depend on image 3 Shown is a schematic diagram of a CNJT adjustable-speed safe intelligent high-power vertical-axis windmill sail of the present invention. The windmill sail blade is composed of a windmill frame 1 and a movable blade bottom surface 20, which can be opened up to nearly 90 degrees in both directions, and the appendage 3 on the windmill frame ( image 3 A—A). Under normal circumstances, one side of the blade is loaded to do work, and the other side does not do work. The blade will open nearly 90 degrees upward under the action of wind, automatically allowing the airflow to pass through, reducing the cross-sectional area of ​​the blade into a linear shape, and obtaining work. Moment; when a storm comes, such as Figure 4 Using the technical solution of removing the wind load on the blades on both sides, the appendage 3 on the windmill frame 1 can be rotated 90 degrees, no longer carrying the blades 20 to do work, the air flow will pass through the frame, ...

[0169] Figure 5 Shown is the telescopic schematic diagram of the appendages on the frame of the CNJT adjustable-speed safe intelligent high-power vertical-axis windmill sail of the present invention.

[0170] The windmill sail blade is composed of the windmill frame 1 and the bottom surface of the movable blade 20, which can be opened up to nearly 90 degrees in both directions. The appendage 3 on the windmill frame normally carries one side blade 20 to do work, and the other side does not do work. The blade 20 will be under the action of wind force. The bottom can be opened nearly 90 degrees upwards, automatically allowing the airflow to pass through, so that the cross-sectional area of ​​the blades 20 is reduced into a linear shape, and the work torque is obtained; Figure 6 The appendage 3 on the windmill frame can be moved and indented. The frame no longer carries the blades to do work. The airflow will pass through the frame. load.

Abstract

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.

Description

technical field [0001] The invention of CNJT's speed-adjustable, safe, intelligent, and high-power vertical-axis windmill sail involves fields: land, island, and offshore wind energy utilization, wind power generation, and sailing power for rivers, lakes, and ocean ships, or power generation for ships and ocean platforms. Background technique [0002] Wind energy is considered to be the best renewable energy. As an inexhaustible green energy source, the wind power industry is the world's renewable energy, except for water energy resources. The technology is the most mature and has the most potential. Power generation methods with large-scale development and commercial development prospects. Because of its outstanding role in reducing environmental pollution, reducing greenhouse gas emissions, and promoting sustainable development, it has been paid more and more attention by countries all over the world. Global wind energy is about 2.74×10 9 MW, of which the available wind ...
