Description

Technical Field

[0001] This utility model relates to the field of vibration power generation, specifically a multi-oscillator-based vortex-induced vibration power generation device. Background Technology

[0002] With global energy demand continuing to rise and environmental protection receiving increasing attention, developing clean and renewable energy has become a key task for the world today. Vortex-induced vibration is a fluid-structure interaction phenomenon that occurs when fluid flows around a bluff body structure such as a cylinder. As the fluid flows through the bluff body, periodic vortices alternately fall off from both sides, causing the bluff body to vibrate periodically. This vibration contains a large amount of energy, and if it can be effectively captured and converted into electrical energy, it can open up new pathways for the utilization of renewable energy.

[0003] Currently, most existing vortex-induced vibration power generation devices adopt a single oscillator structure, which has defects such as low energy capture efficiency and unstable power generation. The vibration amplitude and frequency of a single oscillator are limited, making it difficult to fully tap the energy potential. Furthermore, they have weak adaptability to fluids and weak anti-interference ability, and their power generation performance is prone to fluctuation with changes in the fluid environment. Therefore, developing a vortex-induced vibration power generation device that can improve energy capture efficiency and enhance power generation stability is of great practical significance.

[0019] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0020] Please see Figures 1 to 4This utility model provides a technical solution: a multi-oscillator-based vortex-induced vibration power generation device, including a power generation structure 1, which is provided with several groups, and two sets of cables 2 are fixed between two adjacent groups of power generation structures 1. The power generation structure 1 includes an upper power generation structure 11, a rotating frame 13 is fixedly connected to the bottom of the upper power generation structure 11, and a lower power generation structure 12 is fixedly connected to the bottom of the rotating frame 13.

[0021] This vibration power generation device is designed specifically for areas with rapid water flow. When the water flow continuously impacts the power generation structure 1, the powerful water flow becomes the driving energy. The oscillator 117 inside the power generation structure 1 moves under the impact of the water flow, and the built-in spring 113 can drive the oscillator 117 to return to its original position after it moves. This process is repeated, and the mover 116 connected to the oscillator 117 will continuously cut magnetic field lines in the stator 115, thereby generating electrical energy. Furthermore, the power generation structure 1 is equipped with multiple sets, which can be flexibly assembled and used according to the actual water flow conditions and power generation needs of different environments.

[0022] The upper power generation structure 11 includes a guide plate 111, a clamping member 112 is fixedly connected to the rear end of the guide plate 111, and an oscillator 117 is rotatably connected inside the clamping member 112.

[0023] One end of the vibrator 117 is fixedly connected to a mover 116. There are two sets of movers 116. The surfaces of the two sets of movers 116 are slidably connected to stators 115. A connector 114 is fixedly connected between the two sets of stators 115.

[0024] A spring 113 is fixedly connected to the top of the connector 114, and one end of the spring 113 is fixedly connected to the rear side of the guide plate 111.

[0025] The guide plate 111 has a design that is narrow at the top and wide at the bottom, and the bottom end of the guide plate 111 is fixedly connected to the top end of the rotating frame 13;

[0026] During installation, multiple sets of power generation structures 1 are combined using cables 2. The combined sets of power generation structures 1 are block-shaped and can be tied to the surface of an underwater column with ropes. When water flows over the column, it will generate periodic vortices on both sides, causing the power generation structure 1 to vibrate periodically.

[0027] At this time, the water flow will impact the guide plate 111. The guide plate 111 transmits the force to the oscillator 117 through the clamping member 112. The oscillator 117 drives the two sets of moving parts 116 to move backward. The moving parts 116 slide in the stator 115. At this time, as the guide plate 111 is impacted, it will compress the spring 113 to contract. After the spring 113 contracts to a certain extent, it rebounds outward, driving the guide plate 111 to reset forward. At this time, the guide plate 111 drives the oscillator 117 to move forward. This cycle is repeated to realize that the oscillator 117 drives the moving parts 116 to cut magnetic field lines in the stator 115, thereby generating an induced electromotive force and realizing the conversion of mechanical energy into electrical energy.

[0028] The lower power generation structure 12 has the same structure as the upper power generation structure 11, but is arranged in an upside-down shape.

[0029] The rotating frame 13 has a two-section structure. The rotating frame 13 consists of two sets of rotating rods and two sets of bases. The bases are fixed at the corresponding guide plates 111. The rotating rods are rotatably connected to the bases, and the two sets of rotating rods are rotatably connected to each other.

[0030] When in use, the rotating frame 13 itself can play a certain buffering role to avoid excessive water flow impact force, which could cause the upper power generation structure 11 and the lower power generation structure 12 to separate. When the water flow impacts, the two sets of rotating rods inside the rotating frame 13 rotate to adjust the gap between the upper power generation structure 11 and the lower power generation structure 12 to adapt to the flow of water.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
