DETAILED DESCRIPTION OF THE PREFERRED

Embodiments

Please refer to FIGS. 1 to 6, which are the schematic diagrams of various embodiments of the present invention. As shown in these figures, the present invention is a vortex dynamic power generation structure which consists of the cylindrical cavity 1, the driving mechanism 2 and the power generating mechanism 3.

As shown in FIG. 1, the cylindrical cavity 1 has plural fluid inlets 11 on the side surface and single fluid outlet 12 at the center of the top surface. The external fluid flows into the cylindrical cavity 1 tangentially through the fluid inlet 11, and exits through the fluid outlet 12. As shown in FIGS. 1a and 1b, the fluid inlet 11 has the flow regulator 13. The flow regulators 13 control the fluid inlets 11 to regulate the volume, pressure and speed of the inflow 41.

As shown in FIG. 1, the driving mechanism 2 is installed inside of the cylindrical cavity 1.

As shown in FIG. 2a, in the first embodiment of the present invention, the driving mechanism 2 consists of the rotating shaft 21 and the blade set 22. The rotating shaft 21 is located at the center of the cylindrical cavity 1, and the blade set 22 is connected to the rotating shaft 21. Thrusting the blade set 22 can drive the rotating shaft 21, and the power generating mechanism 3 to be driven by mechanism 2 accordingly.

As shown in FIG. 2b, in the first embodiment of the present invention, a blade set 22 consists of a radially distributed brackets 221 and plural permeable blades 222. The brackets 221 are connected to the rotating shaft 21, and the permeable blades 222 are attached to the brackets 221 or directly attached to the rotating shaft 21 (as shown in FIG. 2d). The permeable blades 222 can be mesh shape (as shown in FIG. 2b), grid shape (as shown in FIG. 2c), bar shape (as shown in FIG. 2d) or separated plane shape (as shown in FIG. 2e). The blade 222 is permeable, so that the inflow 41 will crash but maintain the spiral route 51 and accelerates. The inner part of blade 222 is thrusted by the vortex with higher speed, and can feedback extra kinetic energy to outer part of the blade.

As shown in FIGS. 3a and 3b, in the first embodiment of the present invention, the cylindrical cavity 1 has the heater 23 inside to accelerate the fluid. All kinds of heating sources including wasted heat can be applied.

As shown in FIG. 3b, the power generate mechanism 3 is connected to and driven by the driving mechanism 2, so that a electric generator 31 in the power generating mechanism 3 can produce electricity.

As shown in FIGS. 4a and 4c, the present invention guides the external fluid (such as wind) to flow tangentially into the cylindrical cavity 1. The inflow 41 accelerates along the inner surface of the cavity 15 due to persistent pressure behind, then proceeds along the spiral route 51 until approaching the axis 16, and finally turns toward the outlet 12. A flow field from the fluid inlet 11 to the fluid outlet 12 is thus formed. The pressure at the fluid inlet 11 is the highest. The atmosphere wind direction is perpendicular to the axis 16 or outflow 42, and the axis 16 or the outflow 42 is perpendicular to the spiral route 51, so that the pressure de-escalates from the inlet 11 to the axis 16, and from axis 16 to the outlet 12 (Bernoulli's effect) while the inflow 41 accelerates along the same route. The cylindrical cavity 1 has created a wind field similar to a tornado.

As shown in FIGS. 4a and 4c, the pressure de-escalates from the inlet 11 to the axis 16. The molecule 43 of the inflow 41 proceeds along the spiral route 51 suffers the pressure gradient force 52 that toward the axis 16 and the Coriolis force 53 that perpendicular to the spiral route 51. The above two forces generate the combined vector force 54 which increases the velocity “v” of the fluid molecule 43. Meanwhile, the turning radius of the fluid molecule 43 shrinks along the spiral route 51 which causes angular velocity “ω” to escalate. According to the formula that Coriolis force F=−2 m(ωv), F, ω and v increase simultaneously due to interactive feedback. The unique structure of the cylindrical cavity 1 accelerates the inflow 41 automatically.

As shown in FIGS. 5a and 5b, the second embodiment of the present invention is the structure that automatically accelerate the inflow 41 in the cylindrical cavity 1. The inlet 11 is funnel shaped to accept more inflow 41.

As shown in FIGS. 4a, the inflow 41 accelerates along the spiral route 51 and thrusts the blade set 22 (As shown in FIG. 2a). The inner part of the blade set 22 suffers more thrust than the outer part, which means extra power is fed back to the outer part of the blade set 22 and the inflow 41.

Please refer to FIG. 6, in the third embodiment of the present invention, at least one end of the rotating shaft 21 of the driving mechanism 2 to be provided with a connecting portion (not shown in the figure). In case stacking plural cylindrical cavities 1 to constitute the vortex dynamic power generation structure, plural driving mechanisms 2 in plural cylindrical cavities 1 can be connected, and the power generating mechanism 3 is connected to the terminal driving mechanism 2. The center part of end surfaces between plural cylindrical cavities are opened for fluid to pass through. The power generating mechanism 3 can be the combination of several electric power generators to match various wind scale.

Please refer to FIG. 7, in the first embodiment of the present invention, the baffles 19 are installed out of the fluid inlets 11 to increase the volume, pressure and velocity of the inflow.

In the first embodiment of the present invention, the cylindrical cavity 1 can be installed in the river or the sea current and apply water as inflow 41. The power generating mechanism 3 to be installed on the top of the cylindrical cavity 1, a fluid outlet 12 to be at the bottom with drainpipe toward downstream. The flow speed at inner surface of the cavity 15 is slower which causes higher pressure. The Coriolis force 53 of the inflow 41 together with the pressure gradient force 52 generate the combined vector force 54, which accelerates the inflow 41 to flow toward the axis 16 then turns downward to fluid outlet 12. The inflow 41 thrusts the blade set 22 and rotates the rotating shaft 21, which drives the rotating shaft 21 of the power generating mechanism 3 to generate electricity.
