Description

Technical Field

[0001] This invention relates to an energy recovery device. Background Technology

[0002] Industrial chimneys are crucial facilities in industrial production. However, factors such as high-speed winds and earthquakes can damage them, making it a challenge to reduce the impact of vibration on their lifespan. To address this issue, this invention presents a mechanical device that converts the vibrational motion of an industrial chimney into electricity, aiming to collect electrical energy, mitigate vibration, and extend the chimney's lifespan. The device converts the vibrational force into rotational motion to drive a generator and produce electricity. Mechanical devices such as racks and pinions are used to convert the chimney's vibration into rotational motion, and the generator collects the energy. Previously, no similar device designed in this study could effectively reduce vibration and collect vibrational energy from industrial chimneys. This is a green and environmentally friendly method of utilizing renewable energy, aligning with the current global trend of low-carbon and energy-saving development. The device has a simple mechanical structure and will not significantly affect the functionality and effectiveness of the industrial chimney. Since the airflow and vibration experienced by the external environment are continuous, energy collection is also sustainable. Because industrial chimneys suffer reduced lifespans from significant vibrations and incur high construction and maintenance costs, this external vibration-damping energy harvesting device can fundamentally reduce maintenance costs and is economically feasible. This device can also directly power low-power industrial equipment such as industrial chimney monitoring systems, structural health monitoring sensors, wind speed and flue gas detection equipment, aviation obstruction lights, and communication modules, enabling industrial chimneys to be self-sufficient in energy and reducing the cost of relying on external power sources.

[0003] In popular products for medium-sized and ultra-high industrial chimneys, when the column lengths are 150dm, 200dm, and 300dm, the column swing amplitude can reach more than 25° when the wind speed reaches 2m / s or higher. A swing angle of 25° can satisfy the back-and-forth movement of a 600mm long rack. Meanwhile, when the rack lengths are 400mm, 800mm, 1400mm, and 1800mm, the total power output of the entire system is approximately 90kW, 245kW, 350kW, and 410kW, showing an approximately linear growth trend. In summary, with the increase of rack stroke, wind speed, and industrial chimney height, the energy recovery capability of this invention shows a significant enhancement trend. Summary of the Invention

[0004] To design a high-efficiency, safe, automatic, and vibration-damping energy harvesting device to extend the service life of industrial chimneys and reduce maintenance costs, this invention proposes the following technical solution: An industrial chimney vibration-damping energy harvesting device, wherein the lower end mounting plate of a metal cylindrical column is fastened to the upper end of the industrial chimney by screws i. Three sets of power generation mechanisms are evenly distributed at 120-degree angles on the same horizontal plane between the upper and lower small flanges and between large rings i and ii, respectively. Each set of power generation mechanisms has a rack with one end fastened by bolts i between the upper and lower small flanges. Guide rail brackets i and ii are fixed to the two ends of the back of the rack, respectively. A stop block with a central circular hole is fixed by a pin within the semicircular part of a U-shaped frame. A spring-loaded sliding rod passes through the circular hole of the stop block and is fixed between guide rail brackets i and ii. A through hole is provided at the tail end of the U-shaped frame. Large rings i and ii are both locked in place by bolts ii on the rings. The gear shaft screw i passes through the large ring i, the through hole at the tail end of the U-shaped frame, the large driving gear, the large ring ii, the small driving gear, and is locked by the nut i from top to bottom. The large driving gear i meshes with the rack. The gear shaft screw ii passes through the large ring i, the large driven gear, the large ring ii, the small driven gear, and is locked by the nut ii from top to bottom. The large driven gear ii meshes with the large driving gear. The motor is fixed to the bottom surface of the mounting bracket, and the gear on the motor shaft meshes with the small driving gears and small driven gears on both sides. The end cover covers the small flange. Both gear shaft screws i and ii have bearing bushes in the holes through which they pass through the large rings i and ii, respectively. The outer diameter of the bearing bush has an interference fit clearance with the hole, while the inner diameter of the bearing bush has a sliding fit clearance with the outer diameter of the gear shaft screw. When there are four sets of power generation mechanisms installed between the upper and lower small flanges and between large rings i and ii, respectively, fixed on the top of the column, they are evenly distributed at 90 degrees on the horizontal plane. When the height of the industrial chimney is in the range of 60 to 120m, the number of horizontal installation layers of the power generation mechanisms installed on the top of the column can be increased to no more than 4 layers.

[0005] The beneficial effects of this invention are as follows: This technical solution converts linear motion into unidirectional rotational motion through a motion mechanism, driving the generator gear to rotate clockwise to generate electricity for its own lighting and other equipment. Furthermore, it can absorb vibrations through its own swaying, preventing damage to the industrial chimney structure and thus extending its lifespan. Attached Figure Description

[0017] Industrial chimney vibration damping energy harvesting device, from Figure 1 , Figure 2 and Figure 9Partially synthesized, it can be seen that the lower end base 24 of the metal cylindrical column 12 is fastened to the upper end of the industrial chimney 25 by screws i-13. The feature is that three sets of power generation mechanisms are evenly distributed at 120 degrees on the same horizontal plane between the upper small flange 3 and the lower small flange 4, and between the large rings i-2 and ii-7, respectively, fixed above the column 12. Each set of power generation mechanisms has a bolt i-14 fastened at one end to the upper small flange 3 and the lower small flange 4. The rack 18 between the flanges 4 has guide rail brackets i-6 and ii-15 fixed at its two ends on its back side, respectively. A sleeve 26 with a central hole is fixed by a pin 27 within the semicircular portion of the U-shaped frame 5. A sliding rod 16 with a spring 19 passes through the central hole of the sleeve 26 and is fixed between guide rail brackets i-6 and ii-15. The tail end of the U-shaped frame 5 has a through hole 28. Large rings i-2 and ii-7 are both secured by bolts ii- on the rings. 17. Locking space: The gear shaft screw i-20 passes through the large ring i-2, the through hole 28 at the tail end of the U-shaped bracket 5, the large driving gear 8, the large ring ii-7, the small driving gear 9, and is locked by the nut i-30-1 from top to bottom. The large driving gear 8 meshes with the rack 18. The gear shaft screw ii-20 passes through the large ring i-2, the large driven gear 21, the large ring ii-7, the small driven gear 22, and is locked by the nut ii-30-2 from top to bottom. The driven gear 21 meshes with the large driving gear 8. Gear shaft screws i-20 and ii-20 pass through holes in large rings i-2 and ii-7 respectively, each equipped with a bearing 29. There is an interference fit clearance between the outer diameter of the bearing 29 and the hole, and a sliding fit clearance between the inner diameter of the bearing 29 and the outer diameter of the gear shaft screw. The motor 11 is fixed to the bottom surface of the mounting bracket 23, and the gear 10 on the motor shaft meshes with the small driving gears 9 and small driven gears 22 on both sides. The end cover 1 covers the upper small flange 3.

[0018] Furthermore, when this industrial chimney vibration damping energy harvesting device is installed on an industrial chimney 25 with a height between 60 and 120 meters, the number of horizontally mounted power generation mechanisms above the column 12 can be increased to a maximum of four layers. This is to ensure more uniform force distribution on the device. Consequently, the power generation mechanisms installed between the upper small flange 3 and the lower small flange 4, and between the large circular rings i-2 and ii-7, are arranged in four groups, evenly distributed at 90 degrees on the horizontal plane.

[0019] from Figures 3 to 4 In the enlarged view, we can clearly see that the large ring i-2 and the large ring ii-7 are connected in series by the gear shaft screw i-20 to form the U-shaped frame 5. The guide rail bracket i-6 is fixed to the slide rod 16, which is equipped with a spring 19. The slide rod 16 is fixed to the U-shaped frame by the pin 27 through the sleeve 26, so that they are combined into a whole.

[0020] from Figures 5 to 6It can be observed that there is a chassis 24 under the modified end cover 1 at the upper end of the column 12. The upper small flange 3 and the lower small flange 4 are fixed to the upper and lower ends of the column 12, respectively. A power generation mechanism is set in between. There are two large circular rings i-2 and ii-7 on it, which are locked by bolts ii-17 to create a space for circular movement. The gear shaft screw i-20 passes through the large circular ring i-2, the through hole 28 at the tail end of the U-shaped frame 5, the large driving gear 8, the large circular ring ii-7, and the small driving gear 9 from top to bottom, so that it can transmit momentum more stably. The gear shaft screw ii-20 passes through the large driven gear 21, the large circular ring ii-7, and the small driven gear 22 from top to bottom and meshes with its corresponding large driving gear 8 and small driving gear 9 respectively. Finally, the motor 11 is fixed on the bottom surface of the mounting bracket 23 to ensure its stability. The gear 10 on the motor shaft meshes with the small driving gear 9 and the small driven gear 22 on both sides to ensure the continuity of power transmission.

[0021] from Figures 7 to 8 As can be seen from the enlarged view, the back of the rack 18 is fastened to the guide rail bracket ii-15 by bolts i-14. A slide rod 16 is sandwiched between the guide rail bracket i-6 and the guide rail bracket ii-15, and a spring 19 is fitted on it. It is fastened to the U-shaped frame 5 by a pin 27 through the round hole in the middle of the sleeve 26. The through hole 28 at the rear end of the U-shaped frame 5 also provides convenience for the subsequent installation of parts.

[0022] from Figure 9 As can be seen, the gear shaft screw i-20 passes through the bearing 29, large ring i-2, large driving gear 8, large ring ii-7, and small driving gear 9 from top to bottom, and is locked by nut i-30-1. Meanwhile, the gear shaft screw ii-20 passes through the bearing 29, large ring i-2, large driven gear 21, large ring ii-7, and small driven gear 22 from top to bottom, and is locked by nut ii-30-2. The corresponding large driving gear 8 and large driven gear 21, and small driving gear 9 and small driven gear 22 mesh with each other. Finally, the motor 11 is fixed on the bottom surface of the mounting bracket 23 to ensure that there is no shaking. The gear 10 on the motor shaft meshes with the small driving gear 9 and small driven gear 22 on both sides to ensure the continuity of power transmission.

[0023] Working principle of the industrial chimney vibration damping energy harvesting device of this invention: 1. Rack 18 generates electricity through linear propulsion: When the lower end of the metal cylindrical column 12, the base plate 24, is fastened to the upper end of the industrial chimney 25 by screws i-13, when the industrial chimney 25 is subjected to a frontal wind (east, south, west, north) or various other mainstream wind directions, it will inevitably cause the industrial chimney 25 to vibrate and sway. This vibration or sway will cause the column 12 to sway, causing the small flange 3 fixed on the upper part of the column and the small flange 4 fixed on the lower part of the column to vibrate, thereby inevitably pushing the three racks 18 fixed in the middle of the two large rings i-2 and ii-7 along... The slide bar 16 moves in a straight line to collect kinetic energy. Next, since the rack 18 meshes with the large driving gear 8, the large driving gear 8 rotates counterclockwise and the small driving gear 9 meshes with it rotates clockwise. The two small driven gears connected in series through the gear shaft screw i-20 and gear shaft screw ii-20 on the same axis rotate in the same direction. When the linear propulsion motion is performed, the small driving gear 9 will rotate counterclockwise, driving the gear 10 on the motor shaft to rotate clockwise, driving the motor 11 to generate electricity, thereby effectively collecting energy.

[0024] 2. Rack 18 generates electricity via linear resetting motion: When the device completes the above process, the linear propulsion motion of the rack 18 is completed and a linear reset motion is performed. Due to the release of the elastic potential energy of the spring 19, the rack 18 resets. When the rack 18 resets, the large driving gear 8 meshing with it rotates clockwise and the coaxial small driving gear 9 rotates clockwise. At this time, the large driven gear 21 meshing with the large driving gear 8 rotates counterclockwise and the coaxial small driven gear 22 also rotates counterclockwise. At this time, the small driven gear 22 drives the gear 10 on the motor shaft to rotate clockwise, so that the motor 11 generates electricity and completes the kinetic energy recovery.

[0025] Based on the two consecutive motion-based power generation methods described above, the industrial chimney vibration damping energy harvesting device can continuously harvest the kinetic energy generated by the chimney under wind or vibration conditions. It also converts the vibrations caused by wind and other factors into usable electrical energy.

[0026] This device can operate continuously within a natural wind speed range of 1-20 m / s. Based on estimates of existing industrial chimney vibration energy and typical wind field parameters, this device can capture approximately 5-50 W / m of usable mechanical energy from the lateral vibration of industrial chimneys. Therefore, it is applied to medium-sized and ultra-tall industrial chimneys such as cement industry chimneys, exhaust towers, and ventilation towers. For medium-sized industrial chimneys with a height of approximately 60-120m, this device can be configured with multiple layers (2-4 layers) for installation, with a total power generation of 300-800W. For ultra-tall industrial chimneys greater than 120m, the energy recovery potential is theoretically even higher, reaching levels exceeding 1kW. Installed at the chimney opening, it collects the kinetic energy generated by industrial chimney vibration and reduces industrial chimney vibration without affecting the original function of the industrial chimney. By recovering and utilizing the vibration of existing industrial chimneys, it converts the originally harmful mechanical energy into clean electricity, aligning with the global trend of low-carbon and sustainable development.

[0027] It can significantly reduce the maintenance and operating costs of industrial chimneys. On the one hand, vibration damping protection can extend the structural life of industrial chimneys, avoiding high repair or new construction costs caused by wind and fatigue damage. On the other hand, the generated electricity can be used by the industrial chimney's own equipment, saving on external electricity costs. For medium and ultra-high industrial chimneys, this device has the potential for large-scale application. The power generation capacity increases with the height of the industrial chimney and wind speed, and it can operate continuously over a wide wind speed range, generating sustained economic benefits in the long term. In addition, its structure is simple; except for part number 5, named the U-shaped frame, which is a stamped part, it is basically composed of standard parts, widely used components, low cost, easy to process and install, and has good prospects for promotion.
