Description

The present invention relates to a turbine power generation structure, and in particular refers to a mechanism that uses a cylindrical chamber to generate a vortex flow and accelerate it, and also uses a group of transparent vanes within the cylindrical chamber to collect kinetic energy in the vortex flow. This relates to a turbine power generation structure.

Traditional large horizontal axis wind turbines have weak blades, a high center of gravity, a complex structure, difficult manufacturing, transportation, construction and maintenance, are dangerous to birds, generate noise, and are difficult to replace and replace. Disassembly and recovery are difficult, the service life is short, and the cost is high.

Conventional vertical axis wind turbines have the disadvantage that it is difficult to increase their size because the vertical axis and blades are weak and cannot withstand strong winds.

A conventional turbine power generation structure includes, for example, Patent Document 1, and the obvious differences between Patent Document 1 and the present application are as follows.

The wind collecting tower of Patent Document 1 has an inner wall and an outer wall, a space is provided between the inner wall and the outer wall, the top end of the wind collecting tower is completely opened, and the bottom part and the lower air advancing chamber are in communication. , the airflow entering the rectangular airflow chamber does not form a vortex, so the airflow does not automatically accelerate like a tornado.

On the other hand, the cylindrical chamber of the present application has a single-layer wall structure, and its top end is covered entirely except for the center, and its bottom end is not provided with an opening or an air advancing chamber, so that the air flow After entering through the fluid inlet, it is discharged through the fluid outlet at the center of the apex. Therefore, a complete wind field similar to a tornado is formed inside the cylindrical chamber. The turbine and rotating shaft of Patent Document 1 are installed between the wind collecting tower and the wind advance chamber, and the blades of the turbine do not have a permeable structure, so when the airflow passes through the blades only once, the blades lose kinetic energy. It was not possible to accelerate the airflow by feedback.

On the other hand, in the present application, a plurality of permeable vanes and a drive shaft are provided inside the cylindrical chamber, and no air advance chamber is provided, so that even after the inflow fluid hits the plurality of permeable vanes, the helical path is maintained. It is possible to accelerate while moving, and increase the vortex like a tornado.

As a result of CFD (Computational Fluid Dynamics) simulation of the fluid in the cylindrical chamber of the present invention, the inventor found that a vortex is generated in the cylindrical chamber, and the flow velocity of the vortex is slow at the outer periphery and fast at the center, so that the outer periphery is under high pressure. As a result, the center became low pressure, and the center of the vortex headed toward the exit. The six characteristics mentioned above are the same as for cyclones and tornadoes. Therefore, based on the above-mentioned principle, we researched and developed a new device to solve the problems of conventional wind power generation.
