Airfoil power generating device and operating method thereof

Abstract

The airfoil power generation device includes a base, a central column, and an airfoil assembly. The base has a first contact element. The central column has a second contact element. The airfoil assembly is movably mounted on the central column and has a wingtips and a tail. When the airfoil assembly continuously descends vertically, causing the eccentric wheel at the wingtips to approach and abut against the contact area of ​​the push-pull element, the tail tilts downward relative to the wingtips, giving the airfoil assembly an upward buoyancy force in the vertical direction, causing it to approach the second contact element. When the airfoil assembly continuously rises vertically, causing the push-pull element to move closer to the central column and away from the eccentric wheel, the contact area of ​​the push-pull element separates from the eccentric wheel, causing the tail tilts upward relative to the wingtips, and the airfoil assembly moves closer to the first contact element due to the downward gravity in the vertical direction.

Description

Airfoil generator and its operation method This disclosure relates to a power generation device and its operating method, and more particularly to an airfoil power generation device and its operating method that changes the upward buoyancy of the airfoil component by adjusting the tilt of the tail of the airfoil component relative to the tip of the airfoil component. Generally, traditional power generation equipment requires kinetic energy to drive the power generation components to move in order to convert potential energy into electrical energy. For example, a traditional wind turbine uses airflow to drive fan blades, causing the motor to rotate and generate mechanical energy, which is then converted into electrical energy. Since the geometry of the fan blades and the wind angle affect the drag and lift on the blades, improving the potential energy generated by the fan blades to increase the converted electrical energy and thus improve the power generation efficiency of the wind turbine is a research goal for those with general knowledge in the field. One of the technical embodiments disclosed herein is an airfoil power generation device, which changes the upward buoyancy of the airfoil component by adjusting the tilt of the tail of the airfoil component relative to the top of the airfoil component, thereby causing the airfoil component to repeatedly shift in the vertical direction between the first contact member and the second contact member to generate electricity and thus improve the application value of the airfoil power generation device. The disclosed embodiments provide an airfoil power generation device, which includes a base, a central column, and an airfoil assembly. The base has a fixed base and a first contact member disposed on the fixed base. The central column is disposed on the fixed base of the base and located on one side of the first contact member. The first contact member is adjacent to a first end of the central column, and the central column has a second contact member at a second end relative to the first end. The airfoil assembly is movably disposed on the central column and has an airfoil top and an airfoil tail abutting the airfoil top. The bottom surface of the airfoil top has a rising aperture, and the top surface of the airfoil top relative to the bottom surface has a falling aperture. Between the top and bottom surfaces of the airfoil top, there is a push-pull member and an eccentric wheel rod disposed on one side of the push-pull member. The push-pull member has an abutment area and a hook area relative to the abutment area. As the airfoil assembly descends vertically and the first contact passes through the rising hole to contact the eccentric wheel, causing the eccentric wheel at the wing tip to approach the abutment area of ​​the push-pull member, the tail of the wing tilts downward relative to the wing tip, giving the airfoil assembly vertical buoyancy and causing it to approach the second contact of the central pillar. As the airfoil assembly ascends vertically and the second contact passes through the descending hole to contact the latch area of ​​the push-pull member, causing the push-pull member to move closer to the central pillar and away from the eccentric wheel, the abutment area of ​​the push-pull member separates from the eccentric wheel, causing the eccentric wheel to move towards the bottom surface and the tail of the wing to tilt upward relative to the wing tip. Due to the downward gravity in the vertical direction, the airfoil assembly approaches the first contact of the base member. According to one embodiment of the present disclosure, the push-pull member at the top of the airfoil assembly has a first elastic member disposed between the abutment area and the latch area. When the second contact member passes through the descending hole and contacts the latch area of ​​the push-pull member, the first elastic member is compressed to make the push-pull member move closer to the central column and away from the eccentric wheel rod. After the abutment area of ​​the push-pull member separates from the eccentric wheel rod and the tail of the wing tilts upward relative to the top of the wing, the second contact member and the latch area of ​​the push-pull member gradually separate to reset the first elastic member. According to one embodiment of the present disclosure, the eccentric wheel rod at the top of the airfoil assembly has a second elastic element. When the abutting area of ​​the push-pull member separates from the eccentric wheel rod, the second elastic element is used to drive the eccentric wheel rod to move toward the bottom surface of the top of the airfoil, so that the eccentric wheel rod abuts against the bottom surface of the top of the airfoil and the tail of the airfoil is tilted upward relative to the top of the airfoil. According to one embodiment of this disclosure, the airfoil power generation device further includes a first power generation component, a second power generation component, and a fixed pulley system. The first power generation component is disposed around a central column. The central column is hollow and has a movement space. The second power generation component is disposed in the movement space of the central column, and the weight of the second power generation component is the same as the weight of the airfoil component. The opposite ends of the fixed pulley system are respectively connected to the second power generation component and the airfoil component. The second power generation component is used to reciprocate relative to the first power generation component in a vertical direction within the movement space of the central column via the fixed pulley system and the airfoil component. According to one embodiment of the present disclosure, the abutment area of ​​the push-pull member at the top of the airfoil assembly has a first inclined surface and an abutment top surface relative to the first inclined surface. When the first contact member contacts the eccentric wheel rod through the rising hole, the eccentric wheel rod moves along the first inclined surface of the abutment area to be positioned on the abutment top surface of the abutment area. According to one embodiment of the present disclosure, the latch area of ​​the push-pull member at the top of the airfoil assembly has a contact space, and the second contact member has a second inclined surface, which is further used to pass through the contact space to abut against one side of the latch area. Another technical aspect disclosed herein is an operating method for an airfoil power generation device. This method involves adjusting the tilt of the tail of the airfoil component relative to the tip of the airfoil to change the upward buoyancy of the airfoil component. This causes the airfoil component to repeatedly shift vertically between the first contact and the second contact to generate electricity, thereby enhancing the application value of the airfoil power generation device. The disclosed embodiments provide an operating method for an airfoil power generation device. This operating method includes: an airfoil assembly movably mounted on a central column, wherein the central column is mounted on a fixed base of a base member; the base member has a first contact member mounted on the fixed base, the first contact member being adjacent to a first end of the central column; and the central column has a second contact member at a second end relative to the first end; the airfoil assembly has a wingtips and a wingtip connected to the wingtips; the bottom surface of the wingtips has a rising hole, and the top surface of the wingtips relative to the bottom surface has a descending hole; the wingtips have a push-pull member and an eccentric wheel rod disposed on one side of the push-pull member between the top and bottom surfaces; the push-pull member has an abutment area and a hook area relative to the abutment area. When the airfoil assembly continues to descend vertically and the first contact passes through the rising hole to contact the eccentric wheel rod, causing the eccentric wheel rod at the top of the wing to approach the abutment area of ​​the push-pull member, the tail of the wing tilts downward relative to the top of the wing, giving the airfoil assembly an upward buoyancy in the vertical direction, causing it to approach the second contact of the central column member; and when the airfoil assembly continues to ascend vertically and the second contact passes through the descending hole to contact the hook area of ​​the push-pull member, causing the push-pull member to approach the central column member and move away from the eccentric wheel rod, the abutment area of ​​the push-pull member separates from the eccentric wheel rod, causing the eccentric wheel rod to move towards the bottom surface and the tail of the wing to tilt upward relative to the top of the wing, and the airfoil assembly approaches the first contact of the base member due to the downward gravity in the vertical direction. According to one embodiment of this disclosure, the operation method of the airfoil power generation device further includes: arranging a first power generation component around a central column, wherein the central column is hollow and has a moving space; arranging a second power generation component in the moving space of the central column, wherein the weight of the second power generation component is the same as the weight of the airfoil component; and connecting the second power generation component and the airfoil component respectively through opposite ends of a fixed pulley system, so that the second power generation component reciprocates relative to the first power generation component in the vertical direction within the moving space of the central column via the fixed pulley system and the airfoil component. According to one embodiment of this disclosure, when the second contact member passes through the descending hole and contacts the hook area of ​​the push-pull member, the first elastic member of the push-pull member is compressed to make the push-pull member move closer to the central column and away from the eccentric wheel rod. After the push-pull member separates from the eccentric wheel rod in the abutting area and the tail of the wing tilts upward relative to the top of the wing, the second contact member and the hook area of ​​the push-pull member gradually separate to reset the first elastic member. According to one embodiment of this disclosure, after the abutting area of ​​the push-pull member separates from the eccentric wheel rod, the second elastic element of the eccentric wheel rod drives the eccentric wheel rod to move toward the bottom surface of the wing top, so that the eccentric wheel rod abuts against the bottom surface of the wing top and the wing tail tilts upward relative to the wing top. In summary, in this disclosure, when the airfoil assembly of the airfoil power generation device continues to descend vertically and the first contact passes through the rising hole to contact the eccentric wheel rod, thereby driving the eccentric wheel rod at the top of the wing to approach the abutment area of ​​the push-pull member, the tail of the wing tilts downward relative to the top of the wing, causing the airfoil assembly to have an upward buoyancy in the vertical direction and approach the second contact of the central column. When the airfoil assembly continues to ascend vertically and the second contact passes through the descending hole to contact the hook area of ​​the push-pull member, thereby driving the push-pull member to approach the central column and move away from the eccentric wheel rod, the abutment area of ​​the push-pull member separates from the eccentric wheel rod, causing the eccentric wheel rod to move towards the bottom surface and the tail of the wing tilts upward relative to the top of the wing. Due to the downward gravity in the vertical direction, the airfoil assembly approaches the first contact of the base member. In this way, by adjusting the tilt of the tail of the airfoil relative to the top of the airfoil, the upward buoyancy of the airfoil is changed, thereby causing the airfoil to repeatedly shift vertically between the first contact and the second contact to generate displacement energy. The displacement energy is then converted into electrical energy by the power generation component, thereby increasing the application value of the airfoil power generation equipment.

Figure 1 shows a perspective view of an airfoil power generation device 100 according to an embodiment of the present disclosure. Figure 2 shows a perspective view of the airfoil power generation device 100 of Figure 1 from another perspective. Figure 3 shows a cross-sectional perspective view of an airfoil assembly 130 according to an embodiment of the present disclosure. Figure 4 shows a cross-sectional perspective view of the airfoil assembly 130 of Figure 3 from another perspective. In Figures 1 to 4, the airfoil power generation device 100 includes a base member 110, a central column member 120, and an airfoil assembly 130. The base member 110 has a fixed base 112 and a first contact member 114 disposed on the fixed base 112. The central column member 120 is disposed on the fixed base 112 of the base member 110, and the central column member 120 is located on one side of the first contact member 114 of the base member 110. The first contact 114 of the base member 110 is adjacent to the first end of the central column member 120, while the second end of the central column member 120 relative to the first end has a second contact 124. That is, the opposite ends of the central column member 120 have a first contact 114 and a second contact 124, respectively. In some embodiments, the airfoil assembly 130 is movably mounted on the central post 120 and has a wingtips 132 and a tail portion 134 abutting the wingtips 132. Specifically, the airfoil assembly 130 is adjusted in position by the tail portion 134 to reciprocate along the central post 120 between the first contact member 114 and the second contact member 124. The bottom surface 131 of the wingtips 132 has a rising aperture O1, while the top surface 133 of the wingtips 132 relative to the bottom surface 131 has a falling aperture O2. Furthermore, the wingtips 132 has a push-pull member 1322 between the top surface 133 and the bottom surface 131, and an eccentric wheel rod 1324 disposed on the side of the push-pull member 1322. The push-pull member 1322 of the wingtips 132 has an abutment area 1321 and a latching area 1323 relative to the abutment area 1321. In other words, the push-pull component 1322 has an abutment area 1321 and a latch area 1323 on its opposite sides. In some embodiments, the push-pull member 1322 of the airfoil assembly 130's wingtop 132 has a first elastic member 1326 disposed between the abutment area 1321 and the latching area 1323. Furthermore, the eccentric wheel rod 1324 of the airfoil assembly 130's wingtop 132 further has a second elastic member 1328. The abutment area 1321 of the push-pull member 1322 of the airfoil assembly 130's wingtop 132 has a first inclined surface 1325 and an abutment top surface 1327 relative to the first inclined surface 1325, while the latching area 1323 of the push-pull member 1322 of the airfoil assembly 130's wingtop 132 has a contact space E, and the second contact member 124 has a second inclined surface 1245. Please refer to Figures 5 to 7. Figure 5 shows a side view of the airfoil power generation device 100 in operation according to an embodiment of this disclosure. Figure 6 shows a cross-sectional view of the airfoil power generation device 100 in operation. Figure 7 shows a partial enlarged view of the airfoil power generation device 100 in region A of Figure 6. In Figures 3 to 7, the airfoil power generation device 100 further includes a first power generation component 140, a second power generation component 150, and a fixed pulley system 160. The first power generation component 140 is disposed around a central column 120. The first power generation component 140 may be an induction coil, but is not limited thereto. The central column 120 is hollow and has a movement space C. The second power generation component 150 is disposed in the movement space C of the central column 120, and the second power generation component 150 includes a counterweight ring and a permanent magnet, and the weight of the second power generation component 150 is the same as the weight of the airfoil component 130. It is worth noting that the two ends of the fixed pulley assembly 160 are respectively connected to the second power generation component 150 and the airfoil assembly 130. Therefore, by adjusting the position of the tail section 134 of the airfoil assembly 130 to generate or eliminate buoyancy, the weight balance of the second power generation component 150 and the airfoil assembly 130 can be changed, causing displacement changes in the second power generation component 150 and the airfoil assembly 130. This allows the second power generation component 150 to pass through the first power generation component 140 and generate electromagnetic energy. In other words, the second power generation component 150 can reciprocate relative to the first power generation component 140 in the vertical direction V within the moving space C of the central column 120 via the fixed pulley assembly 160 and the airfoil assembly 130, generating induced magnetic energy by repeatedly passing through the first power generation component 140, thereby generating electricity. In other words, the weight of the permanent magnet of the second power generation component 150, which is in a state of weight balance, is the same as the weight of the airfoil component 130. Therefore, the wind force only needs to be greater than the static friction force used to push the top pulley of the fixed pulley assembly 160 to make the airfoil component 130 continuously rise or fall in the vertical direction V, so that the second power generation component 150 moves relative to the first power generation component 140 to generate electromagnetic energy and thus generate electricity. In addition, when the tail 134 of the airfoil component 130 is tilted downward relative to the top 132, the airfoil component 130 has an upward buoyancy in the vertical direction V due to the wind force, thus causing the airfoil component 130 to move closer to the second contact 124 of the central column 120 (as shown by the arrows in Figures 5 and 6). Please refer to Figures 8 to 13. Figure 8 shows a cross-sectional view of the airfoil power generation device 100 according to an embodiment of the present disclosure during operation. Figure 9 shows a partial enlarged view of the airfoil power generation device 100 in region B of Figure 8. Figures 10, 12, and 13 show schematic diagrams of the airfoil assembly 130 according to some embodiments of the present disclosure at different stages of operation. Figure 11 shows a cross-sectional schematic diagram of the airfoil power generation device 100 according to an embodiment of the present disclosure during operation. In Figures 8 to 13, when the airfoil assembly 130 continues to rise in the vertical direction V to approach the second contact member 124 of the central column 120 and reach the final rising position, the second contact member 124 passes through the descending hole O2 and contacts the hook area 1323 of the push-pull member 1322. This causes the push-pull member 1322 to move closer to the central column 120 and away from the eccentric wheel rod 1324, causing the abutment area 1321 of the push-pull member 1322 to separate from the eccentric wheel rod 1324 (as shown in Figure 10). The second inclined surface 1245 of the second contact 124 is further used to pass through the contact space E (see FIG. 3) to abut against one side of the hook area 1323. The eccentric wheel rod 1324 moves toward the bottom surface 131 and the tail 134 is inclined upward relative to the top 132. In this way, the upward buoyancy generated by the tail 134 of the airfoil assembly 130 disappears, and the airfoil assembly 130 moves toward the first contact 114 of the base member 110 due to the downward gravity in the vertical direction V (as shown by the arrow in FIG. 11). Furthermore, when the second contact 124 passes through the descending hole O2 and contacts the latch area 1323 of the push-pull member 1322, the first elastic member 1326 is compressed, causing the push-pull member 1322 to move closer to the central column 120 and away from the eccentric wheel rod 1324. After the abutment area 1321 of the push-pull member 1322 separates from the eccentric wheel rod 1324, causing the tail portion 134 to tilt upward relative to the top portion 132 of the wing, the second contact 124 gradually separates from the latch area 1323 of the push-pull member 1322, allowing the first elastic member 1326 to reset. Furthermore, when the abutment area 1321 of the push-pull member 1322 separates from the eccentric wheel rod 1324, the second elastic member 1328 drives the eccentric wheel rod 1324 to move toward the bottom surface 131 of the wing top 132, so that the eccentric wheel rod 1324 abuts against the bottom surface 131 of the wing top 132, and the wing tail 134 tilts upward relative to the wing top 132. Next, as the airfoil assembly 130 continues to descend along the vertical direction V and reaches its final descent position, the first contact 114 passes through the riser hole O1 and contacts the eccentric wheel rod 1324, causing the eccentric wheel rod 1324 on the wing top 132 to move closer to the abutment area 1321 of the push-pull member 1322. At this point, the wing tail 134 tilts downward relative to the wing top 132, causing the airfoil assembly 130 to have an upward buoyancy along the vertical direction V and move closer to the second contact 124 of the central column member 120. Specifically, when the first contact 114 passes through the riser hole O1 and contacts the eccentric wheel rod 1324, the eccentric wheel rod 1324 moves along the first inclined surface 1325 of the abutment area 1321 to be positioned on the abutment top surface 1327 of the abutment area 1321. In this way, by adjusting the tilt of the tail 134 of the airfoil assembly 130 relative to the top 132 of the wing, the upward buoyancy of the airfoil assembly 130 is changed, thereby causing the airfoil assembly 130 to repeatedly shift in the vertical direction V between the first contact member 114 and the second contact member 124 to generate displacement energy. The displacement energy is then converted into electromagnetic energy by the first power generation component 140 and the second power generation component 150 to generate electricity, thereby improving the application value of the airfoil power generation device 100. The following description will explain how to operate the airfoil generator. The previously described component connections, materials, and functions will not be repeated; they will be stated in the preceding text. Please refer to Figure 14, which illustrates a flowchart of an operation method of an airfoil power generation device according to an embodiment of the present disclosure. The operation method of the airfoil power generation device includes the following steps. First, in step S1, an airfoil assembly is movably mounted on a central column, wherein the central column is mounted on a fixed base of a base member, the base member has a first contact member mounted on the fixed base, and the first contact member is adjacent to a first end of the central column, while the central column has a second contact member at a second end relative to the first end. The airfoil assembly has a wing top and a wing tail connected to the wing top. The bottom surface of the wing top has a rising hole, and the top surface of the wing top relative to the bottom surface has a falling hole. Between the top and bottom surfaces of the wing top, there is a push-pull member and an eccentric wheel rod disposed on one side of the push-pull member. The push-pull member has an abutment area and a hook area relative to the abutment area. Next, in step S2, as the airfoil assembly continues to descend vertically and the first contact member passes through the rising hole to contact the eccentric wheel rod, causing the eccentric wheel rod at the wing tip to move closer to the abutment area of ​​the push-pull member, the tail of the wing tilts downward relative to the wing tip, giving the airfoil assembly an upward buoyancy in the vertical direction, causing it to move closer to the second contact member of the central pillar. Then, in step S3, as the airfoil assembly continues to ascend vertically and the second contact member passes through the descending hole to contact the latch area of ​​the push-pull member, causing the push-pull member to move closer to the central pillar and away from the eccentric wheel rod, the abutment area of ​​the push-pull member separates from the eccentric wheel rod, causing the eccentric wheel rod to move towards the bottom surface and the tail of the wing to tilt upward relative to the wing tip. Due to the downward gravity in the vertical direction, the airfoil assembly moves closer to the first contact member of the base member. The following description will explain each of these steps in detail. Returning to Figures 8 to 13, firstly, the airfoil assembly 130 is movably mounted on the central pillar 120. The central pillar 120 is mounted on the fixed base 112 of the base member 110. The base member 110 has a first contact 114 mounted on the fixed base 112, and the first contact 114 is adjacent to a first end of the central pillar 120. The central pillar 120 has a second contact 124 at a second end relative to the first end. The airfoil assembly 130 has a wingtips 132 and a wingtips 134 connected to the wingtips 132. The bottom surface 131 of the wingtips 132 has an upward aperture O1, and the top surface 133 of the wingtips 132 relative to the bottom surface 131 has a downward aperture O2. The top wing 132 has a push-pull member 1322 and an eccentric wheel rod 1324 disposed on one side of the push-pull member 1322 between the top surface 133 and the bottom surface 131. The push-pull member 1322 has an abutment area 1321 and a hook area 1323 relative to the abutment area 1321. Next, as the airfoil assembly 130 continues to descend in the vertical direction V and the first contact 114 passes through the rising hole O1 and contacts the eccentric wheel rod 1324 to drive the eccentric wheel rod 1324 of the wing top 132 to approach the abutment area 1321 of the push-pull member 1322 to abut against the abutment area 1321, the wing tail 134 tilts downward relative to the wing top 132, so that the airfoil assembly 130 has an upward buoyancy in the vertical direction V and approaches the second contact 124 of the central column member 120. Next, as the airfoil assembly 130 continues to rise in the vertical direction V and the second contact 124 passes through the descent hole O2 and contacts the hook area 1323 of the push-pull member 1322 to drive the push-pull member 1322 closer to the central column member 120 and away from the eccentric wheel rod 1324, the abutment area 1321 of the push-pull member 1322 separates from the eccentric wheel rod 1324, causing the eccentric wheel rod 1324 to move toward the bottom surface 131 and the tail of the wing 134 to tilt upward relative to the top of the wing 132. The airfoil assembly 130 moves toward the first contact 114 of the base member 110 due to the downward gravity in the vertical direction V. Furthermore, a first power generation component 140 can be arranged around the central column 120. The central column 120 is hollow and has a movement space C. A second power generation component 150 can be arranged in the movement space C of the central column 120. The weight of the second power generation component 150 is the same as the weight of the airfoil component 130. Then, the second power generation component 150 and the airfoil component 130 can be connected by the opposite ends of a fixed pulley assembly 160, so that the second power generation component 150 can reciprocate relative to the first power generation component 140 in the vertical direction V within the movement space C of the central column 120 via the fixed pulley assembly 160 and the airfoil component 130. In some embodiments, when the second contact 124 passes through the descending hole O2 and contacts the latch area 1323 of the push-pull member 1322, the first elastic element 1326 of the push-pull member 1322 is compressed, causing the push-pull member 1322 to move closer to the central column 120 and away from the eccentric wheel rod 1324. After the abutment area 1321 of the push-pull member 1322 separates from the eccentric wheel rod 1324, causing the tail portion 134 to tilt upward relative to the top portion 132 of the wing, the second contact 124 gradually separates from the latch area 1323 of the push-pull member 1322, so that the first elastic element 1326 returns to its original position. Furthermore, when the abutment area 1321 of the push-pull member 1322 separates from the eccentric wheel rod 1324, the second elastic element 1328 of the eccentric wheel rod 1324 drives the eccentric wheel rod 1324 to move toward the bottom surface 131 of the wing top 132, so that the eccentric wheel rod 1324 abuts against the bottom surface 131 of the wing top 132 and the wing tail 134 tilts upward relative to the wing top 132.
