The present invention relates to a blade device, and more particularly to a fluid blade device that uses water flow thrust to generate electricity.

In recent years, the development of low-cost and pollution-free power generation systems has been paid more and more attention, such as wind power generation, solar power generation, and hydropower generation. The above-mentioned power generation methods use natural resources to generate electricity, and generate electricity such as oil and coal. It is more environmentally friendly and less polluting. The purpose of the present invention is to provide a fluid blade device that utilizes the hydraulic power of tides or rivers to provide alternative green energy options for the user.

Therefore, the object of the present invention is to provide a fluid blade device of novel construction.

Thus, the novel fluid blade device comprises a rotating unit and an outer tube. The rotating unit includes a rotating shaft extending forward and backward along an axis, and a first blade module coaxially coupled to the rotating shaft, the first blade module being fluidly driven to drive the rotating shaft to rotate in a running direction, the first The vane module has a plurality of radial flow passages extending radially from the center, each radial flow passage being curved from the center opposite to the running direction, and having a first inlet end adjacent to the center for fluid inflow. And a first outlet end that is remote from the center and that supplies fluid.

The effect of the present invention is that the shape of the first blade module and the outer tube are matched to enable the fluid to generate a torque that drives the first blade module to rotate in the running direction when flowing through the radial flow paths. And when the fluid flows out through the first outlet end, the corresponding rib is impacted at the angle, and a reaction force is generated to increase the torque of the first blade module to rotate.

Referring to Figures 1, 2 and 3, a first embodiment of the novel fluidic blade apparatus is adapted to generate electricity using fluids in the water, such as water from rivers or oceans. The fluid blade device comprises an outer tube 1 and a rotating unit 2.

The outer tube 1 includes a tubular body 11 and a plurality of ribs 12 extending inwardly from the tubular body 11. The tube body 11 extends forward and backward along an axis L, and allows fluid to pass therethrough. The tube body 11 has an inner tube surface 111 on the inner side, and a tube inner surface 111 which is recessed around the axis L. Annular groove surface 112. The ribs 12 are arranged at an angular interval from each other about the axis L to the annular groove surface 112, and extend radially inwardly from the annular groove surface 112, and each of the two adjacent ribs 12 cooperate to define a front and rear The extended connecting channel 13 is connected.

The rotating unit 2 is located in the tube body 11 and includes a rotating shaft 21 extending along the axis L, a first blade module 22 coaxially connected to the rotating shaft 21, and a first blade module 22 connected thereto. The second blade module 23 on the side.

The first blade module 22 is driven by the fluid to drive the rotating shaft 21 to rotate in a running direction T. The first blade module 22 has a base wall 221 that is perpendicularly connected to the rotating shaft 21 and traverses the tubular body 11. a front louver wall 222 extending forward from the periphery of the base wall 221, and a plurality of radial flow passages 223 extending radially from the center of the base wall 221 to penetrate the front louver wall 222, the base wall 221 and the front lobes The wall 222 cooperates to define an inlet 224 with an opening facing forward.

In the present embodiment, the front leaf wall 222 has a plurality of blade blocks 225 arranged at an angular interval from the axis 221 around the axis L, and a cover plate 226 disposed on the front side of the blade blocks 225. The blade block 225 is hollow to reduce the overall weight of the front leaf wall 222, and each of the two adjacent blade blocks 225 cooperates to define one of the radial flow paths 223. The cover plate 226 is annular and defines an opening of the inflow port 224.

Each of the radial flow passages 223 is curved by a center edge opposite to the running direction T, and has a first inlet end 227 adjacent to the center and communicating with the flow inlet 224, and a distance from the center and corresponding to the respective ribs 12. First outlet end 228. The first inlet end 227 is for fluid inflow. The first outlet end 228 is for fluid to flow out, and the outflowing fluid flows into one of the connecting channels 13 correspondingly.

The second blade module 23 has a rear blade wall 231 surrounding the axis L and spaced back and forth from the base wall 221 of the first blade module 22, and a plurality of front and rear longitudinal extensions are arranged at an angular interval from each other about the axis L. An axial flow passage 232 recessed in the rear blade wall 231 and a connecting ring wall 233 connecting the base wall 221 and the rear blade wall 231.

The rear leaf wall 231 has a hollow column shape and has an outer annular surface 234 located on the outer side and adjacent to the inner surface 111 of the tube body 11, and a plurality of angularly spaced apart from each other about the axis L and recessed to the outer annular surface Channel 235 of 234. Each channel face 235 cooperates with the inner face 111 of the tubular body 11 to define a respective axial flow passage 232. Each of the axial flow passages 232 is curved by the forward and trailing edges opposite to the running direction T, and has a second inlet end 236 facing forward and for fluid to flow in, and a second outlet end 237 for flowing backwards and for fluid to flow out.

The connecting ring wall 233 and the base wall 221 cooperate with the rear leaf wall 231 to define a communication space 238 surrounding the outer periphery of the connecting ring wall 233. The connecting space 238 is interposed between the connecting flow channel 13 and the axial direction. Between the flow passages 232, fluids that connect the flow passages 13 can flow into the communication space 238, and the fluid of the communication space 238 can flow into the axial flow passages 232.

Referring to FIG. 2, FIG. 3 and FIG. 4, when the novel fluid blade device is implemented, it can be horizontally disposed along the axis L in a water area such as a river or an ocean, and the fluid in the water region flows into the outer tube 1 in a flow direction F. When the fluid flows through the first vane module 22, it is blocked by the cover plate 226 and concentrates into the inflow port 224, and is dispersed into the radial flow passages 223 as fluid flows into each of the radial flow passages 223. When it is in contact with the wall surface of the radial flow path 223, and is guided by the extended shape of the radial flow path 223 to change the flow direction, at this time, the force exerted by the fluid on the wall surface of the radial flow path 223 is The torque that drives the rotation of the first blade module 22 can be generated, and the kinetic energy is transmitted to the first blade module 22. Then, when the fluid flows out through the first outlet end 228, the corresponding rib 12 is impacted at an angle A to generate a reaction force, wherein the angle A is greater than 90 degrees and less than 180 degrees, because the fluid is continuous The fluid is fluid, so that the reaction force can be transmitted back to the wall of the radial flow passage 223 to increase the torque applied to the first blade module 22.

When the fluid flows into the connecting flow path 13, it flows backward and merges into the communication space 238. Since the fluid continuously flows into the communication space 238, the fluid of the communication space 238 is squeezed and pushed backwards into the dispersion. The axial flow channels 232. When the fluid is squeezed into each of the axial flow passages 232, it is guided by the extended shape of the axial flow passages 232 to change the flow direction, and since the axial flow passages 232 have a flat cross section, the fluid flows out of the axial flow. When the channel 232 is spurted backwards and impacts the rear fluid, thereby generating a reaction force. Due to the extending direction of the axial flow passage 232, the reaction force can be in the same direction as the running direction T, and the second blade mold can be Group 23 applies the same torque as the direction of travel T.

The rotation of the rotating shaft 21 can be driven by the torque applied to the first blade module 22 and the second blade module 23, and a generator (not shown) is disposed at the rear end of the rotating shaft 21. Set at the upper end, the generator can convert the kinetic energy of the rotation of the rotating shaft 21 into electric energy. Since the type of the generator is numerous and is a prior art, it is not the focus of the present invention, and therefore will not be described in detail herein.

It should be noted that when the novel fluid blade device is applied to the river, the water level in the upper reaches of the river is generally high, and the water level in the downstream is usually low. Therefore, when the front of the present invention faces the upstream of the river and the rear faces the downstream of the river, The fluid behind the rotating unit 2 may not fill the entire pipe body 11, and even the rear water level only reaches the height of the rotating shaft 21, so that the fluid above the axis L flows out of the axial flow passages 232 and directly contacts the air, and the reaction is reversed. The force is very small and can be ignored, however the fluid below the axis L can still be subjected to a reaction force to apply torque to the second blade module 23.

It is worth mentioning that the novel fluid blade device can also be arranged upright and upright for water flowing up and down. For example, when the water is guided from top to bottom by a water guiding pressure pipe, the axis L is upright and upright. Extending, and the flow vane device has a front end facing upward and a rear end facing downward, and can be driven by the fluid from top to bottom. Therefore, the water flow direction flowing forward or backward or the water flow flowing up and down may be such that the front end of the fluid power blade device faces the flow direction F of the fluid, and is not limited to this embodiment.

In summary, the novel flow blade device is configured to match the shape of the first blade module 22 and the outer tube 1 to enable the fluid to drive the first flow when flowing through the radial flow channels 223. The torque of the blade module 22 rotating in the running direction T, and further transmitted through the design of the second blade module 23, can also generate the same direction as the running direction T when the fluid flows through the axial flow passages 232. The torque is used to increase the overall torque of the rotating unit 2, thereby improving the power generation efficiency of the generator, so that the purpose of the present invention can be achieved.

Referring to FIG. 5 and FIG. 6, the second embodiment of the novel fluid blade device differs from the first embodiment in that the outer tube 1 further includes three inner surfaces 111 disposed on the tube and around the axis L. An extended ring plate 14 and a plurality of baffles 15 arranged at an angular interval from each other about the axis L of the inner surface 111 of the tube. The ring plates 14 are located behind the second outlet end 237 of the axial flow passages 232 and are spaced along the axis L, and the length extending radially inward is increased from the rear to the rear. The baffles 15 are respectively disposed between each two adjacent ring plates 14, and each baffle 15 is connected to the inner surface 111 of the tube and the corresponding two ring plates 14. Of course, each baffle 15 can also be connected only. The inner surface 11 of the tube, or only one of the ring plates 14 is attached.

When the fluent blade device of the present embodiment is used, the difference from the first embodiment is that when the fluid flows out from the axial flow path 232, it flows backward and in the opposite direction to the running direction T, and passes through the ring plates. The arrangement of the baffles 14 and the baffles 15 enables the fluid to directly impact the ring plates 14 and the baffles 15 rearwardly to generate a large reaction force to further increase the torque applied to the rotating unit 2.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
