Description

Technical Field

[0001] The utility model relates to the field of micro-hydropower generation and charging, in particular to a power generation and charging device based on flow-induced vibration and a hydro-piezoelectric generator. Background Art

[0002] Piezoelectric hydroelectric power generation technology uses the piezoelectric effect to convert the kinetic energy of water flow into electrical energy, and is generally suitable for situations with high water velocity or large flow rates. The advantages of this technology lie in its simple structure and relatively high conversion efficiency, but it also faces the challenges of high cost, complex installation, and the need for large water kinetic energy input. Hydraulic flow-induced vibration power generation uses the fluid dynamic pressure generated by water flowing through a specifically designed device to drive mechanical vibrations, which are then converted into electrical energy. This method is generally suitable for water bodies with lower flow rates and smaller flows, and has the advantages of strong adaptability, small equipment size, and relatively low cost, but its efficiency and stability are also affected by fluid properties and environmental conditions.

[0003] Existing micro-hydroelectric charging devices do not have devices for internal water filtration. Silt, small debris, and biological contaminants in the water may directly enter the working parts or electronic components of the device, causing blockage, damage, or even failure. This situation not only affects the performance and life of the device, but also increases the cost and frequency of maintenance and repair. Secondly, since existing devices are not convenient for disassembling and cleaning the filter, once the filter is blocked or accumulates a large amount of impurities, it is difficult for users to effectively maintain it. This not only reduces the reliability and durability of the device, but also limits its long-term operability in actual applications. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1-Figure 3 The utility model provides an embodiment: a power generation and charging device based on flow-induced vibration and hydro-piezoelectric generator, comprising a turbine 1, a mounting ring 2 is fixedly connected to the inside of the turbine 1, a movable ring 3 is slidably connected to the inside of the mounting ring 2, an outer wall of the movable ring 3 is fixedly connected to a plug plate 4, an inner wall of the plug plate 4 is slidably connected to a slide rod 5, one end of the slide rod 5 is fixedly connected to an insert block 6, the other end of the slide rod 5 is fixedly connected to a top block 7, an outer wall of the insert block 6 is fixedly connected to a limiting block 8, an inner wall of the plug plate 4 is fixedly connected to a fixed ring 9, an outer wall of the slide rod 5 is slidably connected to the outside of the slide rod 5, and an outer wall of the slide rod 5 is fixedly connected to a fixed block 6. Connected to the inside of the fixed ring 9, the outer wall of the slide rod 5 is sleeved with a spring 10, the outer wall of the top block 7 is rotatably connected to the movable plate 11, the outer wall of the movable plate 11 is rotatably connected to the turntable 12, the outer wall of the turntable 12 is fixedly connected to the knob 13, and a filter assembly is provided inside the movable ring 3, which is used to filter and screen impurities inside the water flow; the filter assembly includes a filter screen 14, the outer wall of the filter screen 14 is fixedly connected to the inside of the movable ring 3; one end of the spring 10 is fixedly connected to the outer wall of the insert block 6, and the other end of the spring 10 is fixedly connected to the outer wall of the fixed ring 9;

[0024] Specifically, when the filter screen 14 needs to be disassembled and cleaned, by turning the knob 13, the turntable 12 is driven and cooperates with the movable plate 11, thereby dragging the top block 7, which enables the slide rod 5 to pull the plug block 6 and slide it toward the inside of the plug plate 4. During the sliding process of the plug block 6, it cooperates with the fixing ring 9 and compresses the spring 10 until the plug block 6 completely slides out of the interior of the mounting ring 2. This not only ensures the smooth movement of the plug block 6, but also effectively removes impurities on the filter screen 14, thereby ensuring the filtering effect of the water flow inside the device, while improving the practicality of the device and significantly extending its scope of application and service life.

[0025] Reference Figure 1 、 Figure 2 and Figure 4The outer wall of the turbine 1 is fixedly connected to a support base 15, and the interior of the support base 15 is fixedly connected to a fixed sleeve 16. The interior of the turbine 1 is slidably connected to a flexible piezoelectric telegraph 17, and the outer wall of the flexible piezoelectric telegraph 17 is fixedly connected to a vibration column 18; the interior of the fixed sleeve 16 is provided with a push plate 19 symmetrical up and down, the outer wall of the upper push plate 19 is fixedly connected to the interior of the push plate 19, the outer wall of the lower push plate 19 is slidably connected to the interior of the fixed sleeve 16, and the interior of the lower push plate 19 is fixedly connected to the vibration column 18 The outer wall of the fixed sleeve 16 is fixedly connected to the interior of the sliding sleeve 21, and the interior of the sliding sleeve 21 is slidably connected to the bearing 22. The outer wall of the bearing 22 is fixedly connected to the outer wall of the vibrating column 18; the outer wall of the sliding sleeve 21 is provided with a spring 20, and both ends of the spring 20 are fixedly connected to the outer wall of the push plate 19; the outer wall of the bearing 22 is fixedly connected to the toothed plate 23, the outer wall of the fixed sleeve 16 is fixedly connected to the generator body 24, and the output end of the generator body 24 is fixedly connected to the gear 25, and the toothed plate 23 meshes with the gear 25;

[0026] Specifically, when dual-module power generation is required, water flows into the turbine 1, which drives the rotor inside the turbine 1 to rotate, thereby initially realizing power generation. At the same time, the impact of the water flow inside the turbine 1 will also cause the flexible piezoelectric element 17 to shake. This shaking is transmitted through the vibrating column 18, causing the vibrating column 18 to shake up and down. The shaking of the vibrating column 18 pushes the bearing 22 to slide inside the sleeve 21. At the same time, the push plate 19 drives the tooth plate 23 to move up and down through the compression spring 20. The tooth plate 23 and the gear 25 are engaged with each other, so the movement of the tooth plate 23 causes the gear 25 to rotate. Finally, the rotation of the gear 25 drives the connected generator body 24 to generate electricity, which makes it possible to convert the kinetic energy of the water flow into electrical energy, realizing the effect of dual-module power generation. This process not only improves the efficiency of the device, but also significantly improves the efficiency of power generation and the energy conversion rate, while also improving the sustainable utilization of energy.

[0027] Working principle: When the filter screen 14 needs to be disassembled and cleaned, the turntable 12 is driven to rotate by turning the knob 13, so that the turntable 12 can cooperate with the movable plate 11 to drag the top block 7, and then the slide bar 5 is used to pull the plug 6 to slide toward the inside of the plug plate 4. At the same time, the plug 6 will cooperate with the fixed ring 9 to compress the spring 10 when sliding, until the plug 6 completely slides out of the inside of the mounting ring 2, thereby achieving the effect of filtering the water flow entering the inside of the device, preventing impurities from entering the inside of the device, improving the practicality of the device, and extending the scope of application of the device. When dual-module power generation is required, water flows into the inside of the turbine 1, driving the inside of the turbine 1. The piezoelectric element 17 rotates, thereby achieving preliminary power generation. At the same time, when the water flow impacts the inside of the turbine 1, it drives the flexible piezoelectric element 17 to shake, and then transmits it to the vibrating column 18, driving the vibrating column 18 to shake up and down. When the vibrating column 18 shakes, it can drive the bearing 22 to slide inside the sleeve 21, and the push plate 19 can compress the spring 20, thereby driving the tooth plate 23 to move back and forth up and down, and then the tooth plate 23 and the gear 25 are engaged with each other, so that the tooth plate 23 can drive the gear 25 to rotate, and then drive the generator body 24 to generate electricity, thereby achieving the effect of dual-module power generation, improving the efficiency of the device, and increasing the power generation efficiency of the device.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
