Description

Technical Field

[0001] This invention relates to the field of fluid power generation technology, and in particular to a power generation drive mechanism and a power generation device having the same. Background Technology

[0002] New energy power generation refers to the process of generating electricity using solar energy, biomass energy, geothermal energy, hydrogen energy, or fluid energy. Compared to power generation using coal, oil, natural gas, and nuclear power, it reduces the consumption of non-renewable energy sources. Fluid energy includes wind energy, wave energy, tidal energy, and ocean current energy, among others. In the process of generating electricity using fluid energy, the fluid flows through the power generation drive mechanism, causing the rotatable parts of the drive mechanism to rotate. These rotatable parts then drive the input shaft of the generator to rotate, thus completing the power generation process.

[0003] However, the direction of natural forces such as wind, waves, tides, or ocean currents may vary at different times. Therefore, when fluid flows through the generator's drive mechanism, it may cause the rotatable component to rotate forward or backward. If the rotatable component rotates forward, driving the generator's input shaft to rotate forward as well, the generator can produce electrical energy. Conversely, if the rotatable component rotates backward, driving the generator's input shaft to rotate backward, the generator cannot produce electrical energy; in this case, the rotation of the rotatable component is an ineffective rotation process.

[0004] Currently, traditional power generation drive mechanisms have low fluid energy utilization rates, which limits power generation efficiency and output. Summary of the Invention

[0009] Fluid can flow into the duct from either end of the rotating part, driving the swinging side of each swinging part to swing towards the other end of the rotating part, thereby causing the rotating part to rotate in one direction.

[0010] In some specific embodiments, the rotating part is a cylindrical structure;

[0011] The swinging part has a plate-like structure, and its orthographic projection from one side to the other side is a fan-shaped structure.

[0012] In some specific embodiments, the sidewall of the rotating part is provided with a plurality of clearance holes, which are evenly distributed around the axis of the rotating part;

[0013] It also includes a rotating shaft, a limiting component, and a first limiting rod;

[0015] There are multiple limiting components, each corresponding to a different rotating shaft, and they are evenly fixed to the outer wall of the rotating part around the axis of the rotating part; each limiting component includes a second limiting rod and a third limiting rod arranged in parallel.

[0016] There are multiple first limiting rods, all located outside the rotating part, and fixed to one end of the rotating part extending from the rotating part of the multiple rotating shafts, with the axis of the rod perpendicular to the axis of the rotating shaft.

[0017] The curved sides of multiple swing parts are respectively arranged facing the inner wall of the rotating part, and the straight side is fixed to the side wall of the rotating shaft in a one-to-one correspondence with multiple rotating shafts. The multiple swing parts and rotating shafts are alternately arranged around the axis of the rotating part. Each swing part can drive a rotating shaft and a first limiting rod to rotate. The outer wall of one end of each first limiting rod can abut against the side wall of the second limiting rod or the third limiting rod of a limiting member.

[0018] In some specific embodiments, a support frame is also included;

[0019] The support frame is located outside the rotating part, and its inner side is rotatably connected to the outer side of the rotating part.

[0020] In some specific embodiments, the support frame includes a support ring and a connecting rod;

[0021] There are two support rings, which are respectively encircled on the outside of opposite ends of the rotating part;

[0022] There are multiple connecting rods; the two ends of each connecting rod are fixedly connected to two support rings respectively.

[0023] In some specific embodiments, a moving part is also included;

The rotating part is hollow and open at both ends, with a duct inside. The duct allows fluid to flow through and better constrains the flow direction of the fluid, enabling the swinging part to better utilize the kinetic energy of the fluid and improving the utilization rate of the fluid's kinetic energy. The fluid flowing through the duct drives the swinging side of each swinging part to swing towards one end or the other end of the rotating part, causing the rotating part to continuously rotate in one direction. This, in turn, drives the input shaft of the generator to continuously rotate in one direction, ensuring that the rotation process of the rotating part is always an effective rotation process. This effectively improves the utilization rate of fluid energy by the power generation drive mechanism, thereby increasing power generation efficiency and output. Attached Figure Description

In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0041] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," "fixing," "linking," "hinging," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0042] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A drive mechanism for power generation includes a rotating part 110 and an oscillating part 120. The rotating part 110 is hollow and open at both ends. The interior of the rotating part 110 is a duct, one end of which is adapted for transmission connection with the input shaft of a generator. Multiple oscillating parts 120 are disposed within the rotating part 110 and evenly distributed around its axis. Each oscillating part 120 has a fixed side connected to the rotating part 110 on one side and an oscillating side on the other. The fixed side of one of two adjacent oscillating parts 120 is adjacent to the oscillating side of the other. Fluid can flow into the duct from either end of the rotating part 110, driving the oscillating side of each oscillating part 120 to swing towards the other end of the rotating part 110, thereby causing the rotating part 110 to continuously rotate in one direction.

[0043] In this embodiment, the fluid can be wind, waves, tides, or ocean currents. When the fluid is wind, the power generation drive mechanism is mounted on a wind turbine tower or an aircraft. When the fluid is waves, tides, or ocean currents, the power generation drive mechanism is mounted on a floating body or a submarine. One end of the rotating part 110 can be connected to the input shaft of the generator. The rotating part 110 can drive the input shaft of the generator to rotate, thereby enabling the generator to generate electricity. The proximity of the fixed side of one of the two adjacent swing parts 120 to the swing side of the other means that the distance between the fixed side of one of the two swing parts 120 and the swing side of the other is relatively close, while the distance between the swing side of one of the two swing parts 120 and the fixed side of the other is relatively far. This ensures that each swing part 120 drives the rotating part 110 to rotate in the same direction. It should be noted that unidirectional rotation means that the rotating part 110 always rotates counterclockwise around its own axis or always rotates clockwise around its own axis.

[0044] For example, one end of the rotating part 110 is defined as the left end, and the other end as the right end. Fluid can continuously flow into the duct from the left opening of the rotating part 110 and out from the right opening. The fluid flowing from left to right drives the swing side of each swing part 120 to swing to the right, and each swing part 120 drives the rotating part 110 to rotate continuously counterclockwise. Fluid can also continuously flow into the duct from the right opening of the rotating part 110 and out from the left opening. The fluid flowing from right to left drives the swing side of each swing part 120 to swing to the left, and each swing part 120 drives the rotating part 110 to rotate continuously counterclockwise. Regardless of whether the fluid flows from left to right or from right to left, the rotating part 110 always rotates continuously in one direction, thereby driving the input shaft of the generator to rotate continuously in one direction. This ensures that the rotation process of the rotating part 110 is always an effective rotation process, effectively improving the utilization rate of fluid energy by the power generation drive mechanism, thereby improving power generation efficiency and power output. Compared to fixing the oscillating part 120 to the rotating shaft 130, the hollow rotating part can better constrain the fluid flow direction, allowing the oscillating part to better utilize the fluid's kinetic energy and improving the utilization rate of the fluid's kinetic energy. It should be noted that the direction of fluid flow may change multiple times within a certain period, making the situation quite complex. If a mechanical structure is used to actively drive the oscillating part 120, it will not only consume a lot of electrical energy but also require frequent adjustments to the oscillation direction of the oscillating part 120 to adapt to changes in the fluid flow direction, making the mechanism and control system for actively driving the oscillating part extremely complex. Therefore, compared to the traditional method of actively adjusting the oscillation direction of the oscillating part, the oscillating part of the power generation drive mechanism adopts a passive adjustment method. The adjustment of the oscillation direction relies solely on the fluid flow, eliminating the need to consume a lot of electrical energy and actively capture the fluid flow direction to adjust the oscillating part. This simplifies the overall structure, making it easier to manufacture and promote its use.

[0045] In some specific embodiments of the present invention, the rotating part 110 has a cylindrical structure, which avoids the appearance of sharp corners compared to a triangular, square, or rhomboid cross-section. This results in less fluid resistance during rotation, reducing the conversion of kinetic energy into internal energy and thus improving the utilization rate of fluid energy. The oscillating part 120 has a plate-like structure, making it lightweight and allowing for better conversion of fluid energy into kinetic energy, thereby effectively improving the utilization rate of fluid energy. The orthographic projection of the oscillating part 120 from one side to the other is a fan-shaped structure, which, compared to a polygonal structure, also improves the utilization rate of fluid energy.

[0046] In some specific embodiments of the present invention, the sidewall of the rotating part 110 is provided with a plurality of clearance holes, which are evenly distributed around the axis of the rotating part 110. The power generation drive mechanism also includes a rotating shaft 130, a limiting member, and a first limiting rod 150. There are multiple rotating shafts 130, one end of which is located inside the rotating part 110, and the other end extends out of the rotating part 110 through the clearance holes, corresponding one-to-one. There are multiple limiting members, corresponding one-to-one with the multiple rotating shafts 130, and are evenly fixed to the outer wall of the rotating part 110 around the axis of the rotating part 110. Each limiting member includes a second limiting rod 141 and a third limiting rod 142 arranged in parallel. There are multiple first limiting rods 150, all located outside the rotating part 110, and are fixed to the end of the rotating shaft 130 extending out of the rotating part 110, corresponding one-to-one with the multiple rotating shafts 130, with their axes perpendicular to the axes of the rotating shafts 130. Multiple swing parts 120 have their arc-shaped sides facing the inner wall of the rotating part 110, and their straight sides are fixed to the side wall of multiple rotating shafts 130 in a one-to-one correspondence. The multiple swing parts 120 and rotating shafts 130 are alternately arranged around the axis of the rotating part 110. Each swing part 120 can drive one rotating shaft 130 and one first limiting rod 150 to rotate. The outer wall of one end of each first limiting rod 150 can abut against the side wall of a second limiting rod 141 or a third limiting rod 142 of a limiting member. Figure 1 As shown, when the fluid flows from left to right, the fluid drives the swing side of each swinging part 120 to swing to the right. Each swinging part 120 drives a rotating shaft 130 and a first limiting rod 150 to rotate. The outer wall of one end of each first limiting rod 150 abuts against the third limiting rod 142 of each limiting member, thereby forcing the rotating part 110 to rotate counterclockwise around its own axis. When the fluid flows from right to left, the fluid drives the swing side of each swinging part 120 to swing to the left. Each swinging part 120 drives a rotating shaft 130 and a first limiting rod 150 to rotate. The outer wall of one end of each first limiting rod 150 abuts against the second limiting rod 141 of each limiting member, thereby forcing the rotating part 110 to rotate counterclockwise around its own axis. It should be noted that a preset distance is reserved between the axes of the second limiting rod 141 and the third limiting rod 142 of each limiting member. Specifically, the preset distance is 5-15cm. In this way, the rotation angle of each first limit rod 150 and each rotating shaft 130 can be effectively controlled, thereby effectively controlling the swing amplitude of the swing side of each swinging part 120. The overall structure is simple and the manufacturing cost is low. It can effectively control the continuous unidirectional rotation of the rotating part 110, so that the rotation process of the rotating part 110 is always an effective rotation process, which effectively improves the utilization rate of fluid energy by the power generation drive mechanism, thereby improving the power generation efficiency and power generation.

[0047] In some specific embodiments of the present invention, the power generation drive mechanism further includes a support frame 160, which is disposed outside the rotating part 110 and rotatably connected to the outer side of the rotating part 110, thereby effectively supporting the rotating part 110. The rotating part 110 can be mounted on a wind power generation tower, an aircraft, a floating body, or a submarine via the support frame 160.

[0048] In some specific embodiments of the present invention, the support frame 160 includes support rings and connecting rods. There are two support rings, both circular, respectively encircling the opposite ends of the rotating part 110, effectively supporting the opposite ends of the rotating part 110. There are multiple connecting rods, each with its opposite ends fixedly connected to the two support rings. The multiple connecting rods effectively improve the overall structural stability of the support frame 160. Specifically, each support ring has 3-5 mounting holes, evenly distributed along the circumference of the support ring. Correspondingly, there are 3-5 connecting rods, each of which can be a screw, with its opposite ends fixedly connected to the support ring through mounting holes and limiting nuts. This facilitates the assembly, use, disassembly, and maintenance of the support frame 160. The support frame 160 is lightweight, achieving a lightweight design, and its structure is relatively simple, reducing manufacturing costs. In other embodiments, the connecting rods and support rings are connected by welding, resulting in stronger overall structural stability.

[0049] In some specific embodiments of the present invention, each support ring has a plurality of first bearings on one side facing another support ring. The plurality of first bearings are evenly distributed along the circumference of the support rings, and the axis of each first bearing is parallel to the axis of the support ring. The middle of each first bearing is rotatably connected to the support ring via a first support rod, and its sidewall abuts against the outer wall of the rotating part 110. The plurality of first bearings effectively reduce the frictional force from the support frame 160 experienced by the rotating part 110 during rotation, thereby improving the utilization rate of fluid kinetic energy during power generation.

[0050] In some specific embodiments of the present invention, the power generation drive mechanism further includes a moving part 170. There are multiple moving parts 170, at least one of which is located at one end of the rotating part 110 and is capable of moving circumferentially along one of the support rings. At least one is located at the other end of the rotating part 110 and is capable of moving circumferentially along another support ring. The moving part 170 can effectively improve the smoothness and fluidity of rotation between the opposite ends of the rotating part 110, thereby improving the utilization rate of fluid energy.

[0051] In some specific embodiments of the present invention, there are two moving parts 170, respectively disposed on the opposite sides of the two support rings. The middle portions of the two moving parts 170 are fixedly connected to the opposite ends of the rotating part 110. Specifically, each moving part 170 includes a second support rod and two second bearings. The two second bearings are respectively sleeved on the opposite ends of the second support rod. The sidewalls of the two bearings of one moving part 170 abut against the end face of one of the support rings, and the sidewalls of the two bearings of the other moving part 170 abut against the end face of the other support ring. In this way, the smoothness and fluidity of the rotating part during rotation are greatly improved. Moreover, the arrangement of the axes of the two second support rods of the two moving parts 170 being perpendicular to each other and parallel to each other with respect to the axes of the two second support rods further improves the smoothness and fluidity of the rotating part during rotation.

[0052] In some specific embodiments of the present invention, the swing part 120 is made of a rigid material. It should be noted that a rigid material refers to a material with a certain strength that is not easily deformed when subjected to external forces. Compared to flexible materials, the rigid material swing part 120 experiences less deformation when subjected to external forces, requires less energy to start rotating, and reduces rotational inertia, allowing the impact force of the fluid on the swing part 120 to be converted into kinetic energy more quickly. Specifically, the material of the swing part 120 can be steel, iron, manganese, copper, or high-strength non-metallic materials, etc.

[0053] In some specific embodiments of the present invention, the power generation drive mechanism further includes an intercepting net. There are two intercepting nets, one attached to one end of the rotating part 110 and the other attached to the other end of the rotating part 110. The intercepting nets at both ends effectively prevent impurities mixed in the fluid from flowing into the duct, ensuring the stability of the swing part 120's operation, and thus ensuring the stability of power generation.

[0054] A power generation device with a power generation drive mechanism based on the same concept includes a generator and the power generation drive mechanism provided in any of the above specific embodiments, wherein one end of the rotating part 110 is drively connected to the input shaft of the generator.

[0055] In this embodiment, the generator is suitable for fixed installation on a wind power tower, aircraft, floating body, or submarine. The rotating part 110 can drive the input shaft of the generator to rotate, thereby enabling the generator to generate electricity. Regardless of whether the fluid flows from left to right or from right to left, the rotating part 110 continuously rotates counterclockwise, thereby driving the input shaft of the generator to continuously rotate counterclockwise. This ensures that the rotation process of the rotating part 110 is always an effective rotation process, effectively improving the utilization rate of fluid energy by the power generation drive mechanism, thereby improving power generation efficiency and power output.

[0056] In some specific embodiments of the present invention, meshing teeth are provided on the outer wall of one end of the rotating part 110, and meshing teeth are also provided on the outer wall of the generator input shaft. One end of the rotating part 110 is meshed with the outer wall of the generator input shaft through the meshing teeth. The meshing connection effectively improves the transmission accuracy, thereby reducing the energy loss caused by transmission and ensuring power generation efficiency and power output.

[0057] In some other embodiments of the present invention, a gear is provided at one end of the rotating part 110, and a gear is also provided on the input shaft of the generator. One end of the rotating part 110 is connected to the input shaft of the generator via a belt or chain drive. Compared with the form in which the rotating part 110 is directly connected to the input shaft of the generator, the flexible connection form can effectively buffer the impact force and extend the service life of the transmission part and the generator.

[0058] In the description of this specification, the references to terms such as "an embodiment," "some embodiments," "example," "specific example," "a specific embodiment," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention. In this specification, illustrative expressions of the terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
