Description

Technical Field

[0001] This invention relates to a structure for generating electricity using eddy current power, and more particularly to a mechanism for creating and accelerating eddies using a cylindrical cavity, and a device for absorbing the kinetic energy in the eddies using a permeable blade assembly within the cylindrical cavity to generate electricity. Background Technology

[0002] The disadvantages of existing large horizontal axis wind turbines are: fragile blades, high center of gravity, complex structure, difficult manufacturing, difficult transportation, difficult construction, difficult maintenance, danger to birds, noise, and difficulty in replacement, dismantling and recycling. Overall, they have a short service life and extremely high cost.

[0003] The drawback of existing vertical axis wind turbines is that they have fragile vertical axes and blades that cannot withstand strong winds, thus limiting their ability to be scaled up.

[0004] The inventors have noted prior art US4452562A, which has the following technical defects:

[0005] The wind collection tower in the front case has inner and outer walls with a space between them. The top of the wind collection tower is completely open, and the bottom is connected to the air intake chamber below. The airflow entering the square air intake chamber cannot form a vortex, so the airflow will not automatically accelerate like a tornado.

[0006] In the previous case, the turbine and shaft were located between the wind collection tower and the air intake chamber. The turbine blades were not a permeable structure, so the airflow only swept over the blades once, and the blades could not return kinetic energy to accelerate the airflow again.

[0007] Based on the above-mentioned technical shortcomings, there is an urgent need to develop innovative devices to solve all the existing problems in wind power generation. Summary of the Invention

[0008] Tornadoes possess powerful kinetic energy; therefore, this invention creates a small tornado within a simple cylindrical cavity and utilizes a permeable blade assembly within the cylindrical cavity to collect the tornado's kinetic energy for power generation.

[0009] To achieve the above requirements, the following technical means are used in this work:

[0010] The present invention is an eddy current power generation structure, comprising: a cylindrical cavity, a driving mechanism and a power generation mechanism, wherein the driving mechanism is disposed within the cylindrical cavity.

[0011] In the above-mentioned eddy current power generation structure, fluid flows into the cylindrical cavity and forms eddies, which cause the drive mechanism to rotate.

[0012] In the above-mentioned eddy current power generation structure, the drive mechanism is connected to and drives the power generation mechanism.

[0013] In the above-mentioned eddy current power generation structure, the cylindrical cavity has multiple fluid inlets and a single fluid outlet. The fluid inlets are located on the side of the cylindrical cavity, and the fluid outlet is located at the center of the top surface of the cylindrical cavity.

[0014] In the above-mentioned eddy current power generation structure, each fluid inlet has at least one flow regulating part to control the flow rate entering the cylindrical cavity.

[0015] In the above-mentioned eddy current power generation structure, external fluid enters the cylindrical cavity through the fluid inlet in a tangential direction. The inflowing fluid moves along the inner wall of the cylindrical cavity and then flows spirally toward the center to form a eddy. When it approaches the center, the inflowing fluid is squeezed and turns to the top fluid outlet for discharge.

[0016] In the above-mentioned eddy current power generation structure, the drive mechanism includes a rotating shaft and a blade assembly. The rotating shaft is located on the axis of the cylindrical cavity, and the blade assembly is connected to the rotating shaft.

[0017] In the above-mentioned eddy current power generation structure, the blade group has multiple supports that are radially distributed. The blade group is made of multiple transparent blades set on the supports. Each blade can be in the form of a mesh, grid, rod or spaced plate. The blades can also be directly set on the rotating shaft.

[0018] In the aforementioned eddy current power generation structure, the fluid flowing into the cylindrical cavity drives the blade assembly, which in turn drives the rotating shaft to rotate, and the rotating shaft then drives the power generation mechanism to generate electricity.

[0019] In the above-mentioned eddy current power generation structure, the cylindrical cavity has a heater to accelerate the fluid.

[0020] In the above-mentioned eddy current power generation structure, the rotating shaft has a connecting part at at least one end, which can be connected to the power generation mechanism, and can be connected to the majority of the drive mechanisms when the majority of cylindrical cavities and the majority of drive mechanisms inside them are stacked.

[0021] The cylindrical cavity in this case has a single-wall structure, with the top completely covered except for the central part. There is no opening or air inlet at the bottom. The airflow enters through multiple fluid inlets on the side of the cylindrical cavity and exits through the fluid outlet at the center of the top, thus forming a complete wind field similar to a tornado inside the cylindrical cavity.

[0022] In this case, the multiple permeable blades and drive shaft are all inside the cylindrical cavity, without an air inlet chamber. After the incoming fluid impacts the multiple permeable blades, it can still maintain its spiral path and accelerate, creating an enhanced vortex like a tornado. Attached Figure Description

[0061] Please see now Figures 1 to 6 The figures shown are schematic diagrams of various embodiments of the present invention. As shown, the present invention is an eddy current power generation structure, which includes a cylindrical cavity 1, a driving mechanism 2 and a power generation mechanism 3.

[0062] like Figure 1 As shown, the cylindrical cavity 1 has multiple fluid inlets 11 on its sidewalls and a fluid outlet 12 at the center of its top surface. External fluid enters tangentially through the fluid inlets 11 and then flows out through the fluid outlet 12; as shown... Figure 1a and Figure 1b As shown, a flow regulating unit 13 can also be provided at the fluid inlet 11. The flow regulating unit 13 can control the opening or closing of the fluid inlet 11 to regulate the flow rate, pressure and velocity of the inflowing fluid.

[0063] like Figure 1 As shown, the drive mechanism 2 is located inside the cylindrical cavity 1.

[0064] like Figure 2a As shown, in the first embodiment of the present invention, the driving mechanism 2 includes a rotating shaft 21 and a blade assembly 22. The rotating shaft 21 is located at the axial position of the cylindrical cavity 1, and the blade assembly 22 is fixed on the rotating shaft 21. Pushing the blade assembly 22 can drive the rotating shaft 21, so that the driving mechanism 2 generates kinetic energy.

[0065] like Figure 2b As shown, the blade assembly 22 has a radially distributed support 221 and multiple permeable blades 222. The support 221 is connected to the rotating shaft 21, and the multiple blades 222 are mounted on the support 221 or directly mounted on the rotating shaft 21 (e.g., ...). Figure 2d ), the permeable leaves 222 can be net-like (such as Figure 2b ), grid-like (e.g.) Figure 2c ), rod-shaped (such as Figure 2d ) or separate plate-like (e.g.) Figure 2e The blades 222 are permeable, allowing the inflowing fluid 41 to pass through, maintaining its spiral path 51 and accelerating it. The blades 222 can also feed back kinetic energy to further accelerate the vortex.

[0066] like Figure 3a and Figure 3b As shown, the cylindrical cavity 1 has a heater 23 inside to accelerate the fluid. The heater 23 can use various heat sources or waste heat.

[0067] like Figure 3b As shown, the power generation mechanism 3 is connected to the drive mechanism 2 and is driven by the drive mechanism 2 to generate electricity from the generator inside the power generation mechanism 3.

[0068] like Figure 4a and Figure 4c As shown, this invention introduces an external fluid (e.g., wind) tangentially into a cylindrical cavity 1. The inflowing fluid 41, due to continuous pressure from behind, advances along the inner wall 15 of the cylindrical cavity, then follows a spiral path 51 to near the axis 16 before turning towards the fluid outlet 12, creating a flow field within the cylindrical cavity 1 from the fluid inlet 11 to the fluid outlet 12. The air pressure is highest at the fluid inlet 11 and the inner wall 15 of the cavity, and the direction of the outflowing fluid 42 is necessarily perpendicular to the atmospheric wind direction. Therefore, the pressure is lowest at the fluid outlet 12 (Bernoulli effect). The pressure gradually decreases from the inner wall 15 towards the axis 16, while the flow velocity gradually increases from the inner wall 15 towards the axis 16, creating an accelerating flow field inside the cylindrical cavity 1, similar to a tornado.

[0069] like Figure 4a and Figure 4cAs shown, there is a pressure drop between the inner wall 15 of the cavity and the axis 16. The fluid molecules 43 on the spiral path 51 are subjected to the pressure gradient force 52 pointing towards the axis 16, and also to the Coriolis force 53 perpendicular to the spiral path 51. The vector resultant force 54 generated by the Coriolis force 53 and the pressure gradient force 52 increases the velocity v of the fluid molecules 43. The rotation radius of the fluid molecules 43 decreases with the spiral path 51, which increases the angular velocity ω. According to the formula: Coriolis force F = -2m(ωv), F, ω, and v feed back to each other and increase synchronously. The special structure of the cylindrical cavity 1 makes the inflowing fluid 41 automatically accelerate.

[0070] like Figure 5a and Figure 5b As shown, in the second embodiment of the present invention, the fluid inlet 11 is funnel-shaped to increase the flow rate, which is a structure that automatically accelerates the inflow fluid 41 in the cylindrical cavity 1.

[0071] like Figure 4a As shown, the inflowing fluid 41 is accelerated along the spiral path 51, causing the blade assembly 22 (such as...) Figure 2a The blade assembly 22 rotates, but because the inner side of the blade assembly 22 is subjected to a greater thrust than the outer side, the blade assembly 22 is pushed forward further, causing the inflowing fluid 41 to accelerate again, resulting in an interactive feedback between the inflowing fluid 41 and the blade assembly 22.

[0072] Please see Figure 6 As shown in the third embodiment of the present invention, at least one end of the shaft 21 of the drive mechanism 2 may be provided with a connecting part (not shown in the figure). When multiple cylindrical cavities 1 are stacked to form an eddy current power generation structure, multiple drive mechanisms 2 inside can be connected by the connecting part. The connecting part at the very end is connected to the power generation mechanism 3. Each of the multiple cylindrical cavities 1 has an opening in the center of its end face to allow fluid to pass through. The power generation mechanism can be a combination of multiple generators to cooperate with wind power of various levels.

[0073] Please see Figure 7 As shown, in the first embodiment of the present invention, a guide plate 19 is installed on the outside of the fluid inlet 11 to increase the flow rate and velocity of the fluid 41 flowing into it.

[0074] In the first embodiment of the present invention, if water is used as the inflow fluid 41, the cylindrical cavity 1 can be placed in a river or ocean current, the power generation mechanism 3 can be placed at the top of the cylindrical cavity 1, the fluid outlet 12 is located at the center of the bottom end, and a conduit guides it downstream. The inner wall 15 of the cavity has a low flow velocity and a high pressure. The resultant force 54 of the Coriolis force 53 and the pressure gradient force 52 of the inflow fluid 41 causes the inflow fluid to accelerate towards the axis 16 and then downward to the fluid outlet 12. The inflow fluid 41 pushes the blade assembly 22 and the rotating shaft 21, driving the rotating shaft 21 of the power generation mechanism 3 to generate electricity.

[0075] In summary, the eddy current power generation structure of the present invention has multiple fluid inlets located on the vertical surface of the cylindrical cavity, and a fluid outlet located at the center of the top surface of the cylindrical cavity. External fluid enters the interior of the cylindrical cavity tangentially through the fluid inlets and then exits through the top fluid outlet. The drive mechanism located inside the cylindrical cavity includes a rotating shaft and a permeable blade assembly. The flowing fluid impacts the permeable blades to drive the rotating shaft to rotate. Because multiple permeable blades are used, a helical path and acceleration of the fluid can be maintained, and the generator can be driven to generate electricity effectively.
