The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Referring to fig. 1, 2, 3, and 4, a driving mechanism for power generation includes a rotating portion 110 and a swinging portion 120. The rotating portion 110 is hollow and has two open ends. The interior of the rotating part 110 is a duct, one end of which is adapted to be in driving connection with the input shaft of the generator. The swing portion 120 is a plurality of, all locate in the rotation portion 110, and around the axis evenly distributed of rotation portion 110. One side of each of the swing portions 120 is a fixed side connected to the rotating portion 110, and the other side is a swing side. The fixed side of one of the adjacent two swing portions 120 is disposed adjacent to the swing side of the other. Fluid can flow into the duct from any end of the rotating part 110, and the swinging side of each swinging part 120 is driven to swing to the other end of the rotating part 110, so that the rotating part 110 is driven to rotate in one direction continuously.
In this embodiment, the fluid may be wind, waves, tides or ocean currents. When the fluid is wind, the driving mechanism for power generation is arranged on an iron tower for wind power generation or an aircraft. When the fluid is wave, tide or ocean current, the driving mechanism for generating electricity is arranged on the floating body or the submarine. One end of the rotating portion 110 can be in transmission connection with an input shaft of a generator, and the rotating portion 110 can drive the input shaft of the generator to rotate, so that the generator can generate electricity. The fact that the fixed side of one of the two adjacent swinging parts 120 is adjacent to the swinging side of the other swinging part means that the fixed side of one of the two swinging parts 120 is relatively close to the swinging side of the other swinging part, and the swinging side of one swinging part is relatively far from the fixed side of the other swinging part. In this way, the direction in which each swing portion 120 drives the rotation portion 110 to rotate is consistent, and it should be noted that the unidirectional rotation means that the rotation portion 110 always rotates counterclockwise around its own axis or rotates clockwise around its own axis.
For example, one end of the rotating part 110 is defined as a left end, and the other end is defined as a right end. Fluid can continuously flow into the bypass from the left opening of the rotating portion 110 and flow out from the right opening. The fluid flowing from left to right forces the swing side of each swing portion 120 to swing to the right, and each swing portion 120 forces the rotation portion 110 to continuously rotate counterclockwise. Fluid can also continuously flow into the duct from the right opening of the rotating portion 110 and out of the left opening. The fluid flowing from the right to the left forces the swing side of each swing portion 120 to swing toward the left, and each swing portion 120 forces the rotation portion 110 to continuously rotate counterclockwise. No matter fluid flows from left to right or from right to left, the rotating part 110 continuously performs unidirectional rotation all the time, and then the input shaft of the generator is driven to continuously perform unidirectional rotation all the time, so that the rotating process of the rotating part 110 is an effective rotating process all the time, the utilization rate of the driving mechanism for power generation on fluid energy is effectively improved, and the power generation efficiency and the power generation amount are further improved. Compared with the mode of fixing the swing part 120 on the rotating shaft 130, the hollow-structure rotating part can better restrict the flow direction of the fluid, so that the kinetic energy of the fluid can be better utilized by the swing part, and the utilization rate of the kinetic energy of the fluid is improved. It should be noted that the direction of fluid flow may change many times over a period of time, which is complicated by the fact that the direction of fluid flow may change many times. If a mechanical structure is adopted to actively drive the swing portion 120 to swing, not only much electric energy is consumed, but also the swing direction of the swing portion 120 needs to be frequently adjusted to adapt to the change of the fluid flow direction, so that the mechanism and the control system for actively driving the swing portion to swing are extremely complex. Therefore, compared with the traditional form of actively adjusting the swing direction of the swing part, the swing part of the driving mechanism for power generation adopts a passive adjustment form, the adjustment of the swing direction is realized only by depending on the flow of fluid, more electric energy is not required to be consumed, and the flow direction of the fluid is not required to be actively captured to adjust the swing part, so that the whole structure is simplified, and the swing mechanism is easy to produce, manufacture, popularize and use.
In some embodiments of the present invention, the rotating portion 110 is a cylinder structure, and has a triangular, square or rhombic cross section, so that the occurrence of corners is avoided, the resistance of the fluid during rotation is small, the conversion of kinetic energy to internal energy is reduced, and the utilization rate of the fluid energy is further improved. The swing portion 120 has a plate-shaped structure, and the weight of the swing portion is light, so that fluid energy can be better converted into kinetic energy, and the utilization rate of the fluid energy is effectively improved. The orthogonal projection of the swing portion 120 from one side to the other side is a fan-shaped structure, and the utilization rate of fluid energy is also improved compared with a polygonal structure.
In some embodiments of the present invention, the side wall of the rotating portion 110 is provided with a plurality of yielding holes, and the plurality of yielding holes are uniformly distributed around the axis of the rotating portion 110. The driving mechanism for power generation further includes a rotating shaft 130, a limiting member, and a first limiting rod 150. Wherein, pivot 130 is a plurality of, and one end all is located in rotation portion 110, and the other end passes the hole of stepping down with a plurality of holes of stepping down one-to-one and extends to outside the rotation portion 110. The plurality of limiting members correspond to the plurality of rotating shafts 130 one by one, and are uniformly fixed on the outer wall of the rotating part 110 around the axis of the rotating part 110. Each limiting member comprises a second limiting rod 141 and a third limiting rod 142 which are arranged in parallel. The first limiting rods 150 are disposed outside the rotating portion 110, and are fixed to one end of the rotating portion 110, where the rotating portion 110 extends from the rotating portion 130, corresponding to the plurality of rotating shafts 130, and the axes of the first limiting rods are perpendicular to the axes of the rotating shafts 130. The arc sides of the swinging portions 120 are respectively disposed toward the inner wall of the rotating portion 110, a straight side and the rotating shafts 130 are fixed to the side walls of the rotating shafts 130 in a one-to-one correspondence, and the swinging portions 120 and the rotating shafts 130 are alternately disposed around the axis of the rotating portion 110. Each of the swinging portions 120 can drive one of the rotating shafts 130 and one of the first limiting rods 150 to rotate. The outer wall of one end of each first limiting rod 150 can abut against the sidewall of the second limiting rod 141 or the third limiting rod 142 of one limiting member. As shown in fig. 1, when the fluid flows from left to right, the fluid drives the swing side of each swing portion 120 to swing towards right, each swing portion 120 drives a rotating shaft 130 and a first limiting rod 150 to rotate, an outer wall of one end of each first limiting rod 150 abuts against the third limiting rod 142 of each limiting member, and the rotating portion 110 is forced to rotate counterclockwise around its own axis. When the fluid flows from right to left, the fluid drives the swing side of each swing portion 120 to swing towards left, each swing portion 120 drives one rotating shaft 130 and one 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, and then the rotation portion 110 is forced to rotate counterclockwise around the axis of the rotation portion. 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 stopper rod 150 and each rotating shaft 130 can be effectively controlled, and thus the swing amplitude of the swing side of each swing portion 120 can be effectively controlled. The whole structure is simple, the manufacturing cost is low, the rotating part 110 can be effectively controlled to continuously rotate in one direction, the rotating process of the rotating part 110 is always an effective rotating process, the utilization rate of the fluid energy of the driving mechanism for power generation is effectively improved, and the power generation efficiency and the power generation amount are further improved.
In some embodiments of the present invention, the power generation driving mechanism further includes a support frame 160, and the support frame 160 is disposed outside the rotating part 110, and the inner side of the support frame 160 is rotatably connected to the outer side of the rotating part 110, so as to effectively support the rotating part 110. The rotating part 110 can be installed on an iron tower for wind power generation, an aircraft, a floating body, or a submarine through the support frame 160.
In some embodiments of the present invention, the support frame 160 comprises a support ring and a connecting rod. The two support rings are of a circular structure and are respectively arranged outside the two opposite ends of the rotating part 110 in a circle, so that the two opposite ends of the rotating part 110 can be effectively supported. The connecting rod is a plurality of, and the relative both ends of every connecting rod respectively with two support ring fixed connection. The plurality of connecting rods effectively improve the stability of the entire structure of the support frame 160. Specifically, each support ring is provided with 3-5 mounting holes, and the 3-5 mounting holes are uniformly distributed along the circumferential direction of the support ring. Correspondingly, the number of the connecting rods is 3-5, each connecting rod can be a screw rod, and two opposite ends of each connecting rod are fixedly connected with the support ring through mounting holes and limit nuts respectively. Thus, the support frame 160 is convenient to assemble, use, disassemble and maintain. The whole weight of the support frame 160 is light, the lightweight design is realized, the structure is simple, and the manufacturing cost is reduced. In other embodiments, the connecting rod and the support ring are connected in a welding mode, so that the stability of the integral structure is stronger.
In some embodiments of the invention, each support ring is provided with a plurality of first bearings on a side facing the other support ring. The first bearings are uniformly distributed along the circumferential direction of the support ring, and the axis of each first bearing is parallel to the axis of the support ring. The middle part of each first bearing is rotatably connected with the support ring through a first support rod, and the side wall of each first bearing is abutted against the outer wall of the rotating part 110. The plurality of first bearings effectively reduce the friction force from the support frame 160 when the rotation part 110 rotates, thereby improving the utilization rate of fluid kinetic energy during power generation.
In some embodiments of the present invention, the power generation driving mechanism further includes a moving part 170. The moving portion 170 is provided in plurality, and at least one of the moving portions is provided at one end of the rotating portion 110 and can move in a circumferential direction of one of the support rings. At least one of which is provided at the other end of the rotating portion 110 and is movable in the circumferential direction of the other support ring. The moving part 170 can effectively improve the smoothness and smoothness of the rotation of the two opposite ends of the rotating part 110, thereby improving the utilization rate of fluid energy.
In some embodiments of the present invention, two moving portions 170 are provided on the back sides of the two support rings. The middle portions of the two moving portions 170 are fixedly connected to the opposite ends of the rotating portion 110, respectively. Specifically, each moving part 170 includes one second support bar and two second bearings. The two second bearings are respectively sleeved at the two opposite ends of the second supporting rod. The side walls of the two bearings of one moving part 170 are respectively abutted against the end surface of one of the support rings, and the side walls of the two bearings of the other moving part 170 are respectively abutted against the end surface of the other support ring. Thus, the smoothness and smoothness of the rotation of the rotating part are greatly improved. In addition, in the case where the axes of the two second support rods of the two moving portions 170 are perpendicular to each other and the axes of the two second support rods are parallel to each other, the smoothness and smoothness of the rotation of the rotating portion can be further improved.
In some embodiments of the present invention, the material of the swinging portion 120 is a rigid material. Here, the rigid material means a material having a certain strength and being less likely to be deformed when subjected to an external force. Compared with a flexible material, the deformation amount of the rigid swinging part 120 caused by external force is small, the energy required for starting rotation is small, and the rotational inertia is reduced, so that the impact force of the fluid on the swinging part 120 can be converted into the kinetic energy of the swinging part 120 more quickly.
