Description

Tornado wind turbine

technical field

The utility model relates to a tornado wind turbine.

Background technique

Due to the increasing shortage of energy sources and the increasingly serious pollution caused by the combustion of fossil energy, people are interested in the development and utilization of new energy sources. Wind energy is currently the most promising non-polluting renewable energy source. Therefore, more and more government agencies and companies Participated in the development and utilization of wind energy. The key to the utilization of wind energy lies in the design of wind power machinery. A windmill is a simple wind power machine, but its power output is limited. Generally, it can only be used to drive some small mechanical devices, while another type has large rotatable wind blades. The structure of wind power machinery is very complicated, it is not easy to manufacture, install and maintain, and the manufacturing cost is high, so how to develop a wind power machine that is both efficient and simple has attracted more and more attention.

Contents of the invention

The purpose of the utility model is to provide a tornado type wind machine, which not only has reasonable design, high wind energy utilization rate, but also has simple structure and is easy to manufacture and install.

The purpose of this utility model is achieved in the following way: this tornado-type wind power machine comprises upper and lower two spoke-type hoops placed in parallel, and is characterized in that: the center bearings of the upper and lower spoke-type hoops pass through vertically A vertical shaft is provided, and the outer coaxial fixed sleeve in the middle of the vertical shaft is provided with a wind wheel shaft. The wind wheel shaft is provided with a spiral arc-shaped wind-receiving wing, and the lower end of the wind wheel shaft is provided with a wind guiding wing. A loose-leaf grid is arranged on the circumference between the upper and lower ring frames, a windmill wing is arranged on the upper end of the vertical shaft, and a bevel gear transmission pair is arranged on the extended shaft on the lower side of the vertical shaft to drive power generation. machine work.

The notable feature of the utility model is that the resistance when the wind turbine is working is greatly reduced through the arrangement of the spiral arc-shaped wind-receiving wing, the wind-guiding wing and the loose-leaf grid.

At the same time, the design of the spiral arc-shaped wind-receiving wing maximizes the use of multi-directional wind force, the automatic opening and closing design of the windward side and the upwind side of the loose-leaf grid and the design of the multi-stage wind-receiving device maximize the use of the incoming wind force The wind energy of the machine improves the utilization rate of wind energy.

In addition, the tornado wind turbine has a simple structure, is easy to manufacture and install, and has certain practical value.

Detailed ways

The tornado-type wind turbine of the present utility model includes two upper and lower spoke ring frames 1 placed in parallel, and is characterized in that a vertical shaft 3 is vertically pierced through the center bearing 2 of the upper and lower spoke ring frames 1 , the outer coaxial fixed sleeve of the middle part of the vertical shaft 3 is provided with a wind wheel shaft 11, and the wind wheel shaft 11 is provided with a spiral arc-shaped wind-receiving wing 4, and the lower end of the wind wheel shaft 11 is provided with a wind guiding wing 5 , a loose-leaf grid 6 is arranged on the circumference between the upper and lower hoops 1, a windmill wing 7 is provided on the upper end of the vertical shaft 3, and a shaft 8 on the lower side of the vertical shaft 3 is provided with The bevel gear transmission pair 9 is to drive the generator 10 to work.

In order to maximize the utilization of multi-directional wind force, the convex surface of the spiral arc-shaped wind-receiving wing 4 faces forward and slightly upward.

The wind-receiving surface of the above-mentioned windmill blade 7 faces downward, so that the wind force at the outlet of the wind turbine can be used again to drive the wind wheel shaft 11 to work, thereby improving the utilization rate of wind force.

In order to reduce the resistance encountered when the side wind enters the wind turbine, the section of the hinged grid 6 is in the shape of an airfoil.

The above-mentioned helical arc-shaped wind-receiving vane 4 is installed on the radial surface of the wind rotor shaft 11 in a helical shape.

When working, the side wind enters the wind turbine through the opened windward side of the loose-leaf grid 6, and the bottom wind enters the wind turbine through the wind deflector 5, and the two winds converge inside the wind turbine to push the spiral arc-shaped wind receiving wing 4 to move , so as to drive the wind wheel shaft 11 to rotate. At the same time, the confluent wind rotates upward along the spiral arc-shaped wind-receiving wing 4 to form a whirlwind. The rotation of wing 4 drives the wind turbine to work. When the converging wind blows out from the top outlet of the wind turbine, since the top of the wind turbine is provided with a windmill wing 7 facing downwards, the outlet wind will once again push the windmill wing 7 to rotate, thereby driving the wind wheel shaft 11 to work again. A bevel gear transmission pair 9 is provided on the outrigger shaft 8 on the lower side of the vertical shaft 3 of the wind turbine. The bevel gear on the vertical shaft 3 meshes with the bevel gear on the engine 10 to drive the engine 10 to generate electricity.
