Description

Technical Field

[0001] The present invention relates to the technical field of flow-induced vibration power generation, and specifically relates to a multi-oscillator linkage flow-induced vibration power generation device and power generation method with strong stability. Background Art

[0002] The flow-induced vibration phenomenon refers to that when a fluid flows over the surface of a non-linear object, vortices are alternately shed on both sides of it, and a periodic pulsating lift force is generated. If the non-linear object is elastically supported, it will generate periodic vibrations perpendicular to the oncoming flow direction, that is, flow-induced vibration (FIM). The flow-induced vibration phenomenon will generate alternating loads on structures in the engineering field, damage their strength and shorten their service life. However, this vibration phenomenon can also be used to convert the mechanical energy generated by the vibration into electrical energy, so as to continuously generate electricity.

[0003] In the prior art, a flow-induced vibration power generation device needs to set an oscillator in the fluid. The oscillator vibrates under the action of the fluid. During the vibration process, the oscillator can drive the generator to act, so as to convert the kinetic energy of the oscillator into electrical energy. However, the flow velocity of the fluid is not constant. If the flow velocity of the fluid suddenly increases, it will cause the oscillator to vibrate at a high frequency and with a large amplitude, resulting in a significant increase in the alternating load on the oscillator, and it is very easy to cause damage to the oscillator or even the generator. Once a failure occurs, the entire power generation device needs to be shut down for maintenance, resulting in a decrease in the overall power generation efficiency and restricting the popularization and application of the flow-induced vibration power generation device. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0020] AsFigure 1 As shown in the figure, a multi-oscillator linkage flow-induced vibration power generation device with strong stability includes multiple groups of power generation mechanisms distributed along the first direction. The number of power generation mechanisms in each group is at least two, and the power generation mechanisms in the same group are distributed along the second direction, which is perpendicular to the first direction. The power generation mechanism includes an installation cylinder 2 with a closed top. A linear generator 12 is fixedly arranged in the installation cylinder 2. The power input shaft 13 of the linear generator 12 extends downward and is fixedly connected to a lifting plate 18. A transmission rod 3 is rotatably connected to the lower surface of the lifting plate 18. The lower end of the transmission rod 3 is fixedly connected to an oscillator 10. The oscillator 10 is parallel to the fluid surface and is placed in the fluid.

[0021] During use, after the present invention is installed and deployed, the oscillator 10 is located in the fluid and the length direction of the oscillator 10 is perpendicular to the flow direction of the fluid. During the fluid flow, the oscillator 10 can be impacted, causing the oscillator 10 to vibrate up and down. During the upward movement of the oscillator 10, the transmission rod 3 can be pushed upward, and then the lifting plate 18 can be pushed to move synchronously through the transmission rod 3. The lifting plate 18 can also push the power input shaft 13 upward, thereby driving the linear generator 12 to output electrical energy and completing flow-induced vibration power generation. During the downward movement of the oscillator 10, the transmission rod 3, the lifting plate 18, and the power input shaft 13 can be driven to reset downward. In this way, the linear generator 12 can continuously output electrical energy. On the other hand, the flow rate of the fluid is monitored in real time. If the flow rate of the fluid is too fast, the vibration amplitude and vibration frequency of the oscillator 10 may be too high. If this state persists for a long time, the oscillator 10 or other structures may be damaged. To avoid this situation, when the detected flow velocity reaches a preset safety threshold, the transmission rod 3 is rotated, and then the oscillator 10 is driven to rotate synchronously by the transmission rod 3, so that the oscillator 10 rotates to a state where its length direction is parallel to the flow direction of the fluid. At this time, the water-facing area of the oscillator 10 is reduced, and when the fluid impacts the oscillator 10, the vibration amplitude and vibration frequency of the oscillator 10 are greatly reduced, thereby protecting the oscillator 10 and other structures. In this way, the service life of the power generation mechanism can be effectively extended, and the frequency of maintenance can be reduced. In addition, multiple power generation mechanisms cooperate with each other, and the power generation efficiency is higher.

[0022] The present invention can adjust the oscillator 10 according to the flow velocity of the fluid. By changing the water-facing area of the oscillator 10, it is possible to avoid the oscillator 10 having too high a vibration amplitude and vibration frequency when the fluid flow velocity is too fast, realize the protection of the oscillator 10 and other structures, effectively extend the service life of the power generation mechanism, and reduce the frequency of maintenance.

[0023] Such as Figure 2As shown in the figure, in order to facilitate the rotation of the transmission rod 3 and the oscillator 10, an adjustment motor 15 is fixedly arranged in the installation cylinder 2. The adjustment motor 15 is drivingly connected with a rotating shaft 16. A gear 17 is fixedly sleeved on the rotating shaft 16, and the gear 17 passes through the lifting plate 18. A rotating ring 19 is rotatably connected to the lower surface of the lifting plate 18. The rotating ring 19 is coaxially arranged with the transmission rod 3 and is connected by a plurality of connecting rods 22. A rack meshing with the gear 17 is arranged on the inner wall of the rotating ring 19, and the axial length of the gear 17 is greater than the width of the rack. When it is detected that the flow velocity of the fluid reaches the preset safety threshold, the adjustment motor 15 operates and drives the rotating shaft 16 to rotate. The rotating shaft 16 drives the gear 17 to rotate. During the rotation of the gear 17, because the gear 17 and the rack are meshed with each other, the rack can be driven to rotate, and then the rotating ring 19 can be driven to rotate. Finally, the rotating ring 19 drives the transmission rod 3 and the oscillator 10 to rotate synchronously through the connecting rods 22, achieving the effect of changing the direction of the oscillator 10. When the flow velocity of the fluid drops below the safety threshold, the adjustment motor 15 operates in the reverse direction and drives the transmission rod 3 and the oscillator 10 to reset. Through this setting, the direction of the oscillator 10 can be conveniently adjusted, and the action speed is fast, which can fully avoid the damage of the oscillator 10. In addition, because the transmission rod 3, the rotating ring 19 and the lifting plate 18 need to move up and down synchronously during the vibration of the oscillator 10, by making the axial length of the gear 17 greater than the width of the rack, even if the rotating ring 19 moves up and down, the gear 17 can still maintain the meshing state with the rack, ensuring smooth power generation and also ensuring the smooth adjustment of the direction of the oscillator 10.

[0024] As Figure 3As shown, the specific connection method between the lifting plate 18 and the rotating ring 19 is as follows: The lifting plate 18 is fixedly connected with a plurality of extension rods 23 extending downward, and the extension rods 23 are located on the circumferential side of the rotating ring 19. The extension rods 23 are fixedly connected with a limiting rod 24 parallel to the lifting plate 18. A distance is left between the limiting rod 24 and the lifting plate 18 to form a receiving space capable of accommodating the rotating ring 19. During the process that the oscillator 10 vibrates and drives the transmission rod 3 to move upward, the transmission rod 3 can drive the connecting rod 22 and the rotating ring 19 to move upward synchronously, and push the lifting plate 18 to move upward. When the oscillator 10 moves downward, it can also pull the extension rod 23 and the lifting plate 18 to move downward synchronously through the limiting rod 24, so as to ensure that the linear generator 12 can be driven to generate electricity smoothly. On the other hand, when the adjustment motor 15 drives the gear 17 to rotate, the rotating ring 19 can rotate freely in the receiving space, so as to change the directions of the transmission rod 3 and the oscillator 10. In practical applications, since the fluid flow velocity reaches the safety threshold very few times, the direction of the oscillator 10 will not be adjusted frequently, and correspondingly, the rotating ring 19 will not rotate frequently. Therefore, although the rotating ring 19 will have sliding friction with the limiting rod 24 when rotating, it will not cause the rotating ring 19 and the limiting rod 24 to be quickly damaged by friction. Compared with the conventional method of realizing rotational connection through structures such as bearings, this connection method between the lifting plate 18 and the rotating ring 19 is simpler in structure and is not easily unable to rotate smoothly due to corrosion in the humid environment near the fluid.

[0025] As Figure 4 shown, further, the rotating ring 19 and the transmission rod 3 are connected by three connecting rods 22. The three connecting rods 22 are evenly distributed around the circumference of the transmission rod 3, and an included angle of 120° is formed between adjacent two connecting rods 22. The rack is arranged between the two connecting rods 22, and the gear 17 is also located between the two connecting rods 22. Since the oscillator 10 only needs to rotate 90° to rotate to a state parallel to the fluid flow direction, an included angle of 120° formed between the two connecting rods 22 can meet the setting requirements of the rack. On this basis, only three connecting rods 22 are provided, the overall weight is lower, and it is easier for the oscillator 10 to drive the transmission rod 3, the rotating ring 19 and the lifting plate 18 to move upward.

[0026] In order to enable the oscillator 10 to reset more stably after moving upward and driving the linear generator 12, at least one hydraulic rod 14 is fixedly arranged in the mounting cylinder 2. The hydraulic rod 14 is parallel to the power input shaft 13, and the movable end of the hydraulic rod 14 is fixedly connected to the lifting plate 18. When the lifting plate 18 is pushed upward by the oscillator 10, the hydraulic rod 14 can contract. When the oscillator 10 moves downward, the hydraulic rod 14 can be extended by inputting liquid into the hydraulic rod 14, so as to use the hydraulic rod 14 to push the lifting plate 18 downward, and then push the oscillator 10 downward through the rotating ring 19 and the transmission rod 3, achieving the effect of ensuring that the oscillator 10 can reset smoothly.

[0027] In order to prevent the oscillator 10 from moving downward excessively, a limiting ring 20 is fixedly connected to the inner wall of the bottom of the mounting cylinder 2. The limiting ring 20 is located below the lifting plate 18 and the rotating ring 19, and the transmission rod 3 can pass through the inner hole of the limiting ring 20. By setting the limiting ring 20, the rotating ring 19 can be limited, thereby restricting the lowest position of the oscillator 10 and further improving the stability of the overall structure of the power generation mechanism.

[0028] In order to further improve the power generation efficiency of the entire device and avoid interference between different power generation mechanisms, especially to avoid the reduction of energy when the fluid is blocked by one oscillator 10, resulting in a decrease in the vibration amplitude of the oscillator 10 when impacting other subsequent oscillators 10, among multiple power generation mechanisms in the same group, the heights of the oscillators 10 are different. Through this setting, in the same group of power generation mechanisms, different oscillators 10 will be impacted by fluids at different depths, which can avoid interference with each other and ensure that each power generation mechanism has a high power generation efficiency.

[0029] In order to facilitate connecting multiple power generation mechanisms together, so as to facilitate the installation and deployment of the entire device, the power generation mechanism includes a box body 1. The mounting cylinder 2 is arranged in the box body 1, and the mounting cylinder 2 is fixedly connected to the box body 1 through a plurality of connecting strips 11, and all the box bodies 1 are fixedly connected.

[0030] The specific connection method between the transmission rod 3 and the oscillator 10 is as follows: a connecting plate 7 is fixedly connected to the lower end of the transmission rod 3, and the transmission rod 3 is perpendicular to the connecting plate 7. The connecting plate 7 is fixedly connected with two mounting plates 8 parallel to the transmission rod 3. A central shaft 9 is fixedly connected between the two mounting plates 8, and the oscillator 10 is fixedly sleeved on the central shaft 9. In the present invention, the oscillator 10 is in the shape of a triangular prism, and a mounting hole is provided in the middle. The central shaft 9 can pass through the mounting hole so that the oscillator 10 is fixedly sleeved on the central shaft 9. One of the edges of the oscillator 10 faces the direction of the fluid source, so that the fluid can impact the oscillator 10 to cause the oscillator 10 to vibrate. Further, in order to avoid excessive obstruction of the fluid by the connecting plate 7 and the mounting plates 8 and consume the fluid energy, the side edges of the connecting plate 7 and the mounting plates 8 are both set as arc surfaces.

[0031] To enhance the connection strength between the connecting plate 7 and the transmission rod 3 and prevent the connecting plate 7 from falling off, which may cause the oscillator 10 to also fall off, a strengthening component is provided between the transmission rod 3 and the connecting plate 7. The strengthening component includes an upper strengthening plate 4 and a lower strengthening plate 6 arranged vertically. Two mutually parallel vertical strengthening plates 5 are fixedly connected between the upper strengthening plate 4 and the lower strengthening plate 6. The transmission rod 3 passes through the upper strengthening plate 4 and the lower strengthening plate 6 in sequence, and the two vertical strengthening plates 5 are located on both sides of the transmission rod 3. The lower strengthening plate 6 is fixedly connected to the connecting plate 7. The transmission rod 3 is fixedly connected to both the upper strengthening plate 4 and the lower strengthening plate 6. With this structure, there are more connection positions between the transmission rod 3 and the connecting plate 7, thus having a higher connection strength, which can prevent the connecting plate 7, the mounting plate 8, and the oscillator 10 from falling off, ensuring that the power generation mechanism can generate electricity stably. Similar to the connecting plate 7 and the mounting plate 8, in order to avoid excessive obstruction of the fluid by the upper strengthening plate 4, the lower strengthening plate 6, and the vertical strengthening plate 5, the sides of the upper strengthening plate 4, the lower strengthening plate 6, and the vertical strengthening plate 5 are also set as arc surfaces.
