Description

The present invention relates to a turbine power generation structure, and in particular to a mechanism that uses a cylindrical chamber to generate and accelerate vortex flows, and to a turbine power generation structure that uses a set of permeable blades within the cylindrical chamber to collect the kinetic energy in the vortex flows.

Conventional large horizontal axis wind turbines have the following disadvantages: weak blades, a high center of gravity, a complex structure, difficulty in manufacturing, transportation, construction and maintenance, danger to birds, noise pollution, difficulty in replacement, dismantling and recovery, a short service life and high costs.

Conventional vertical axis wind turbines have the disadvantage that they are difficult to enlarge because the weak vertical axis and blades cannot withstand strong winds.

A conventional turbine power generation structure is disclosed, for example, in Patent Document 1, and the obvious differences between Patent Document 1 and the present application are as follows:

The wind collecting tower in Patent Document 1 has an inner wall and an outer wall, with a space between the inner and outer walls, the top end of the wind collecting tower is completely open, and the bottom is connected to the wind advance chamber below, so the airflow entering the square wind advance chamber does not form a vortex, and the airflow does not automatically accelerate like a tornado.

On the other hand, the cylindrical chamber of the present application has a single-wall structure, the top end of which is entirely covered except for the center, and the bottom end is provided with no opening or wind advance chamber, and the airflow enters through multiple fluid inlets on the side of the cylindrical chamber before being discharged from a fluid outlet in the center of the top end. As a result, a complete wind field similar to a tornado is formed inside the cylindrical chamber. The turbine and rotating shaft of Patent Document 1 are provided between the wind collection tower and the wind advance chamber, and because the turbine blades are not of a permeable structure, the blades are unable to feed back kinetic energy to accelerate the airflow if the airflow only passes through the blades once.

In contrast, in the present application, multiple permeable vanes and a drive shaft are provided inside a cylindrical chamber, and no wind chamber is provided, so that even after the inflowing fluid hits the multiple permeable vanes, it can accelerate while maintaining its helical path, and the vortex can be intensified like a tornado.

The inventors conducted a CFD (Computational Fluid Dynamics) simulation of the fluid in the cylindrical chamber of the present invention, and as a result, a vortex was generated in the cylindrical chamber, and because the flow speed of the vortex was slow on the periphery and fast in the center, the periphery was under high pressure and the center was under low pressure, and the center of the vortex moved toward the outlet. The six characteristics described above are the same as those of a cyclone and a tornado. Therefore, based on the above principles, a new device was researched and developed, solving the problems of wind power generation with conventional technology.

FIG.

Please refer to Figures 1 to 6. As shown in Figures 1 to 6, a turbine power generation structure according to one embodiment of the present invention is composed of at least a cylindrical chamber 1, a drive mechanism 2, and a power generation mechanism 3.

Refer to FIG. 1. As shown in FIG. 1, a plurality of fluid inlets 11 are provided on the sidewall of the cylindrical chamber 1. A fluid outlet 12 is provided in the center of the top surface of the cylindrical chamber 1, and an external fluid enters the fluid inlet 11 in a tangential direction and then flows out from the fluid outlet 12. As shown in FIG. 1a and FIG. 1b, a flow rate regulator 13 is provided on the fluid inlet 11. The flow rate regulator 13 can control the opening and closing of the fluid inlet 11 to regulate the flow rate, pressure and flow velocity of the inflowing fluid.

Refer to Figure 1. As shown in Figure 1, the drive mechanism 2 is provided in the cylindrical chamber 1.

First Embodiment
Please refer to Fig. 2a. As shown in Fig. 2a, the driving mechanism 2 according to the first embodiment of the present invention includes a rotating shaft 21 and a set of blades 22. The rotating shaft 21 is provided at the axial position of the cylindrical chamber 1. The set of blades 22 is fixed on the rotating shaft 21. When the set of blades 22 is pushed, the rotating shaft 21 is driven, and kinetic energy is generated in the driving mechanism 2.

Refer to FIG. 2b. As shown in FIG. 2b, the vane group 22 has a frame 221 and a plurality of permeable vanes 222 arranged radially. The frame 221 is connected to the rotating shaft 21. The plurality of vanes 222 are mounted on the frame 221 or directly mounted on the rotating shaft 21 (as shown in FIG. 2d), and the permeable vanes 222 may have a mesh shape (as shown in FIG. 2b), a lattice shape (as shown in FIG. 2c), a bar shape (as shown in FIG. 2d) or a separate plate shape (as shown in FIG. 2e). The vanes 222 are permeable, so that the inflowing fluid 41 can pass through and can be accelerated while maintaining its helical path 51. The vanes 222 can feed back kinetic energy to accelerate the vortex flow.

Refer to Figures 3a and 3b. As shown in Figures 3a and 3b, a heater 23 for accelerating the fluid is provided inside the cylindrical chamber 1. The heater 23 may use various heat sources or waste heat.

Refer to Figure 3b. As shown in Figure 3b, the power generation mechanism 3 is connected to the drive mechanism 2 and is driven by the drive mechanism 2, so that the generator in the power generation mechanism 3 can generate electricity.

Refer to Figures 4a and 4c. As shown in Figures 4a and 4c, the present invention introduces an external fluid (e.g. wind) into the cylindrical chamber 1 in a tangential direction, and the inflowing fluid 41 advances along the cylindrical chamber inner wall 15 with a continuous rearward pressure, then advances near the axis 16 in a spiral path 51, and then turns toward the fluid outlet 12, forming a flow field from the fluid inlet 11 to the fluid outlet 12 in the cylindrical chamber 1. The air pressure at the fluid inlet 11 and the chamber inner wall 15 is the highest, and the direction of the outflowing fluid 42 is always perpendicular to the wind direction of the atmosphere, so the pressure at the fluid outlet 12 is the lowest (Bernoulli's theorem). The pressure gradually decreases as it approaches the axis 16 from the chamber inner wall 15, and the flow velocity gradually increases as it approaches the axis 16 from the chamber inner wall 15, forming a vortex-like accelerated flow field inside the cylindrical chamber 1.

Refer to Figures 4a and 4c. As shown in Figures 4a and 4c, the air pressure between the chamber inner wall 15 and the axis 16 drops, and the fluid molecules 43 on the spiral path 51 are subjected to the pressure gradient force 52 directed toward the axis 16, and the Coriolis force 53 perpendicular to the spiral path 51. The vector composition 54 generated by both the Coriolis force 53 and the pressure gradient force 52 increases the velocity ν of the fluid molecules 43, and the radius of rotation of the fluid molecules 43 shrinks along the spiral path 51, increasing the angular velocity ω. Based on the formula of the Coriolis force F = -2m (ων), the three forces F, ω, and ν feedback each other and increase synchronously, and the special structure of the cylindrical chamber 1 automatically accelerates the inflowing fluid 41.

Second Embodiment
5a and 5b, in the second embodiment of the present invention, the fluid inlet 11 is formed in a funnel shape, which is structured to automatically accelerate the inflowing fluid 41 in the cylindrical chamber 1, thereby increasing the flow rate.

Refer to FIG. 4a. As shown in FIG. 4a, when the incoming fluid 41 accelerates along the helical path 51, the blade set 22 rotates (as shown in FIG. 2a), but the inside of the blade set 22 receives a larger pushing force than the outside, so the blade set 22 further accelerates the incoming fluid 41, and there is an alternating feedback between the incoming fluid 41 and the blade set 22.

Third Embodiment
Please refer to Fig. 6. As shown in Fig. 6, in the third embodiment of the present invention, at least one end of the rotating shaft 21 of the drive mechanism 2 is provided with a connection part (not shown), and when the stacked cylindrical chambers 1 are used as a turbine power generation structure, the connection part is used to connect the multiple drive mechanisms 2 in the stacked cylindrical chambers 1, the connection part at the end part is connected to the power generation mechanism 3, and an opening part for passing a fluid is formed in the center of the end face of the multiple cylindrical chambers 1. The power generation mechanism can respond to various classes of wind power by combining multiple generators.

First Embodiment
Please refer to Fig. 7. As shown in Fig. 7, in the first embodiment of the present invention, a fluid guide 19 may be attached to the outside of the fluid inlet 11 to increase the flow rate and flow velocity of the inflow fluid 41.

In the first embodiment of the present invention, when water is used as the inflow fluid 41, the cylindrical chamber 1 can be installed in a river or ocean current, and the power generation mechanism 3 can be installed at the top end of the cylindrical chamber 1, with the fluid outlet 12 located in the center of the bottom end and guided downstream by a conduit. The chamber inner wall 15 has a low flow rate and high pressure, and the Coriolis force 53 of the inflow fluid 41 and the vector combination 54 of the air pressure gradient force (or water pressure gradient force) 52 accelerate the inflow fluid 41 and guide it to the axis 16, and then it reaches the fluid outlet 12 downward, where the inflow fluid 41 pushes the blade group 22 and the rotating shaft 21, driving the rotating shaft 21 of the power generation mechanism 3 to generate electricity.

As can be seen from the above, the turbine power generation structure of the present invention has multiple fluid inlets on the vertical wall surface of the cylindrical chamber and a fluid outlet in the center of the top surface of the cylindrical chamber, external fluid enters the cylindrical chamber from the fluid inlet in a tangential direction and is then discharged from the fluid outlet at the top end, the drive mechanism provided in the cylindrical chamber includes a rotating shaft and a group of permeable blades, and when the inflowing fluid hits the permeable blades, it rotates the rotating shaft, and since multiple permeable blades are used, the spiral path is maintained and accelerated, allowing the generator to generate electricity efficiently.
