Abstract

A vortex dynamic power generation structure comprises a cylindrical cavity 1, a plural fluid inlet 11 and a fluid outlet 12. A driving mechanism 2 consists of a rotating shaft 21 and the blade set 22, the rotating shaft locates at the axis of the cylindrical cavity, and the blade set consists of brackets (221, Fig 2A) and plural permeable blades 222. The blade set is connected to the rotating shaft, so that the inflow thrusts the blade set and drives the rotating shaft. External fluid flows into the cylindrical cavity tangentially, then flows toward the axis along the spiral route and turns toward the outlet creating a wind field, like a tornado. The inflow maintains a spiral route and acceleration and blades can feedback their rotating power to accelerate the vortex. Preferably an electrical power generating mechanism 3 is driven. The fluid inlets may have a flow regulator 13. A heater (23, Fig 3A) may be provided inside of the cylindrical cavity. The permeable blades may be mesh, grid, bar, or separated plane shape. Baffles (19, Fig 7) at fluid inlets may increase the volume, pressure, and speed of the inflow.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Please refer to Figures 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 Figure 1, the cylindrical cavity 1 has plural fluid inlet 11 at 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 figures la and lb, the fluid inlet 11 has the flow regulator 13. The flow regulators 13 control the opening and closing of the fluid inlets 11 to regulate the volume, pressure and speed of the inflow 41.
As shown in Figure 1, the driving mechanism 2 is installed inside of the cylindrical cavity 1.
As shown in Figure 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 locates at the center of the cylindrical cavity 1, and the blade set 22 is connected to the rotating shaft 21. To thrust the blade set 22 can drive the rotating shaft 21, and the driving mechanism2 can generate kinetic energy accordingly.
As shown in Figure 2b, in the first embodiment of the present invention, the blade set 22 consists of the 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 Figure 2d). The permeable blades 222 can be mesh shape (as shown in Figure 2b), grid shape (as shown in Figure 2c), bar shape (as shown in Figure 2d) or separated plane shape (as shown in Figure 2e). The blade 222 is permeable, so that the inflow 41 can pass through, maintain its spiral route 51 and accelerates. The blade 222 can feedback its kinetic energy to accelerate the vortex.
As shown in Figures 3a and 3b, in the first embodiment of the present invention, the cylindrical cavity 1 has the heater 23 inside to accelerate the 15 fluid. All kinds of heating sources including wasted heat can be applied.
As shown in Figure 3b, the power generating mechanism 3 is connected to and driven by the driving mechanism 2, so that the electric generator 31 in the power generating mechanism 3 can generate electricity.
As shown in Figure 4a and 4c, the present invention guides the external 20 fluid (such as wind) to flow tangentially into the cylindrical cavity 1. The inflow 41 proceeds alongside 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. The flow field from the fluid inlet 11 to the fluid outlet 12 is thus formed, The pressure at the fluid inlet 11 and alongside the inner surface of the cavity 15 5 are the highest, The direction of outflow 42 is certainly perpendicular to the atmosphere wind direction, so the pressure at fluid outlet 12 is the lowest (Bernoulli's effect). The pressure dwindles from the inner surface of cavity 15 to the axis 16 while the velocity escalates from the inner surface of cavity 15 to the axis 16. The cylindrical cavity 1 has created an accelerative 10 flow field inside, similar to a tornado.
As shown in Figures 4a and 4c, the pressure dwindles from the inner surface of the cavity 15 to the axis 16. The fluid molecule 43 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 dwindles along the spiral route 51 which causes angular velocity "w" to escalate. According to the formula that Coriolis force F = -2m(wv), F, w and v increase simultaneously due to interactive feedback. The unique structure of the cylindrical cavity 1 accelerates the inflow 41 automatically.
As shown in Figures 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 Figures 4a, the inflow 41 accelerates along the spiral route 51 and rotates the blade set 22 (As shown in Fig 2a). The inner part of the blade set 22 suffers more thrust than the outer part, the blade set 22 will be further thrust and accelerates the inflow 41, which causes interactive feedback between the inflow 41 and the blade set 22.
Please refer to Figure 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 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 generators to match various wind scale.
Please refer to Figure 7, in the first embodiment of the present 20 invention. The baffles 19 are installed out of the fluid inlets 11 to increase the volume 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, the fluid outlet 12 to be at the bottom with drainpipe 5 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 10 and rotates the rotating shaft 21, which drives the rotating shaft 21 of the power generating mechanism 3 to generate electricity.
In summary, the present invention of vortex dynamic power generation structure, plural fluid inlets are opened at the vertical side of the cylindrical cavity, the fluid outlet is opened at the center of the end surface of the cylindrical cavity. The external fluid enters the cylindrical cavity tangentially through the inlet and exits through the outlet at the top surface. The driving mechanism which is inside of the cylindrical cavity consists of the rotating shaft and the permeable blade set. The inflow thrusts the plural permeable blade set and rotating shaft to turn. By applying plural permeable blades, the inflow can maintain spiral route and accelerate, also to drive the power generating mechanism to generate electricity.
