Detailed Description

Referring now to fig. 1 to 6, schematic diagrams of various embodiments of the present invention are shown, respectively, as follows: the invention relates to an eddy current power generation structure which comprises a cylinder cavity 1, a driving mechanism 2 and a generator 3.

As shown in fig. 1, the sidewall of the cylindrical cavity 1 has a plurality of fluid inlets 11, a fluid outlet 12 is formed in the center of the top surface of the cylindrical cavity 1, and external fluid enters through the fluid inlets 11 in a tangential direction and then flows out through the fluid outlets 12; as shown in fig. 1a and 1b, a flow rate adjusting portion 13 may be provided at the fluid inlet 11. The flow regulator 13 can control the opening or closing of the fluid inlet 11 to regulate the flow rate, pressure and flow velocity of the inflowing fluid.

As shown in fig. 1, the driving mechanism 2 is provided in the cylindrical cavity 1.

As shown in fig. 2a, in the first embodiment of the present invention, the driving mechanism 2 includes a rotating shaft 21 and a blade set 22, the rotating shaft 21 is disposed at the axial position of the cylinder cavity 1, the blade set 22 is fixed on the rotating shaft 21, and the blade set 22 is pushed to drive the rotating shaft 21, so that the driving mechanism 2 generates kinetic energy.

As shown in fig. 2b, the vane set 22 has a radially distributed bracket 221 and a plurality of permeable vanes 222, the bracket 221 is connected to the rotating shaft 21, the plurality of vanes 222 are mounted on the bracket 221 or directly mounted on the rotating shaft 21 (fig. 2 d), and the permeable vanes 222 can be in a net shape (fig. 2 b), a lattice shape (fig. 2 c), a rod shape (fig. 2 d) or a separated plate shape (fig. 2 e). The vanes 222 are permeable so that the incoming fluid 41 can pass through, maintain its helical path 51 and accelerate. The blades 222 may feedback kinetic energy to re-accelerate the vortex.

As shown in fig. 3a and 3b, the cylindrical cavity 1 has a heater 23 inside to accelerate the fluid, and the heater 23 can use various heat sources or waste heat.

As shown in fig. 3b, the power generation mechanism 3 is connected to the driving mechanism 2, and is driven by the driving mechanism 2 to generate power by a generator in the power generation mechanism 3.

As shown in fig. 4a and 4c, the present invention introduces external fluid (e.g., wind) into the cylindrical cavity 1 in a tangential direction, and the inflow fluid 41 advances along the inner wall 15 of the cylindrical cavity due to the pressure sustained in the rear direction, and then advances along the spiral path 51 to approach the axis 16, so as to turn the fluid outlet 12, thereby forming a flow field from the fluid inlet 11 to the fluid outlet 12 in the cylindrical cavity 1. The air pressure at the fluid inlet 11 and the inner wall 15 of the chamber is highest, the direction of the outgoing fluid 42 must be perpendicular to the atmospheric wind direction, so that the pressure at the fluid outlet 12 is lowest (white effort effect), the pressure decreases from the inner wall 15 of the chamber to the axis 16, the flow rate increases from the inner wall 15 of the chamber to the axis 16, and an accelerated flow field is created inside the cylindrical chamber 1, similar to a tornado.

As shown in fig. 4a and 4c, there is a pressure drop between the inner wall 15 of the chamber and the axis 16, the fluid molecules 43 on the spiral path 51 are subjected to a pressure gradient force 52 directed towards the axis 16 and also to a coriolis force 53 perpendicular to the spiral path 51, the resultant vector force 54 generated by both the coriolis force 53 and the pressure gradient force 52 increases the velocity v of the fluid molecules 43, and the radius of rotation of the fluid molecules 43 decreases with the spiral path 51, increasing the angular velocity ω according to the formula: the coriolis force f= -2m (ωv), F, ω, v are fed back to each other and increase synchronously, the special structure of the cylindrical cavity 1 accelerates the inflow fluid 41 automatically.

As shown in fig. 5a and 5b, in the second embodiment of the present invention, the fluid inlet 11 is funnel-shaped to increase the flow rate for the structure of automatically accelerating the inflow fluid 41 in the cylinder chamber 1.

As shown in fig. 4a, the inflow fluid 41 accelerates along the spiral path 51, so that the blade set 22 (as shown in fig. 2 a) rotates, but the inner side of the blade set 22 receives a larger thrust force than the outer side, so that the blade set 22 is pushed forward further, and the inflow fluid 41 accelerates again, so that the feedback of interaction between the inflow fluid 41 and the blade set 22 is achieved.

Referring to fig. 6, in a third embodiment of the present invention, at least one end of the rotating shaft 21 of the driving mechanism 2 may be provided with a connection portion (not shown), when the stacked cylindrical cavities 1 are in a vortex power generation structure, the connection portion may be used to connect the plurality of driving mechanisms 2 therein, the end-most connection portion is connected to the power generation mechanism 3, and the center of the end faces of the cylindrical cavities 1 are provided with openings for allowing fluid to pass through; the power generation mechanism can be a combination of a plurality of generators to match wind power of various grades.

Referring to fig. 7, in the first embodiment of the present invention, a baffle 19 is installed at the outer side of the fluid inlet 11 to increase the flow rate and the flow velocity of the inflow fluid 41.

If water is used as the inflow fluid 41, the cylindrical cavity 1 may be placed in a river or ocean current, the power generation mechanism 3 may be placed at the top end of the cylindrical cavity 1, the fluid outlet 12 may be placed at the center of the bottom end, and a conduit may be led downstream, as in the first embodiment of the present invention. The inner wall 15 of the cavity has lower flow velocity and higher pressure, and the resultant force 54 of the coriolis force 53 and the air pressure gradient force 52 of the inflow fluid 41 accelerates the inflow fluid to flow to the axis 16 and then to the fluid outlet 12, and the inflow fluid 41 pushes the blade set 22 and the rotating shaft 21 to drive the rotating shaft 21 of the power generation mechanism 3 to generate power.
