Description

Technical Field

[0001] This invention belongs to the field of energy recovery and utilization technology, and specifically relates to a vibration energy recovery device. Background Technology

[0002] With the rapid development of rail transit and the Internet of Things (IoT), many low-power, independently distributed electrical appliances have been applied in the rail transit field. However, since these appliances are primarily powered by electrochemical batteries, they inevitably require frequent, periodic maintenance and pose potential environmental pollution risks, hindering the development of rail transit and the IoT. This is especially true for remote or tunnel-like railway environments, where power transmission is difficult and manual maintenance costs are high. To address these issues, many researchers have developed and designed self-powered systems that can recover available energy from the environment to power electrical appliances (such as sensors).

[0003] Wind, solar, and mechanical vibration energy are currently the main energy sources for self-powered electricity research. However, the harvesting of wind and solar energy is limited by weather conditions. When heavy-haul trains run on tracks, the tracks and the surrounding roads generate strong vibrations, which produce energy much higher than that of ordinary railway tracks. How to utilize track vibration energy for power generation has become a focus of research in the rail transit industry. Summary of the Invention

[0004] This invention discloses a vibration energy recovery device, which aims to solve the technical problem of how to utilize the high-frequency vibration energy of trains to generate electricity when heavy-haul trains run on the track and the surrounding roads generate strong vibrations, which are much higher than the vibration energy of ordinary railway tracks.

[0005] To solve the aforementioned technical problems, the present invention adopts the following technical solution:

[0006] A vibration energy recovery device includes a force-bearing rod, a mounting base, a generator, a rotating device, and a transmission device. One end of the force-bearing rod is hinged to the mounting base. The rotating device includes a rotating shaft, a support base, and a gear set. There are two support bases, which are spaced apart below the force-bearing rod along its thickness direction. Both ends of the rotating shaft are rotatably connected to the two support bases, and the rotating shaft is driven to the main shaft of the generator through the gear set. The transmission device drives the force-bearing rod and the rotating shaft. When the force-bearing rod swings up and down, it drives the rotating shaft to rotate through the transmission device.

[0007] In this technical solution, when it is necessary to collect the energy generated by track vibration, the entire device is installed between two adjacent sleepers. Specifically, the mounting base is placed between two adjacent sleepers, and the end of the force-bearing rod furthest from the mounting base is installed below the rail. When the rail vibrates, the rail causes the force-bearing rod to swing up and down. After the force-bearing rod swings up and down, the power is transmitted to the rotating shaft through a transmission device, causing the rotating shaft to rotate. After the rotating shaft rotates, the power is transmitted to the main shaft of the generator through a gear set, causing the main shaft of the generator to rotate, thereby converting mechanical energy into electrical energy. In summary, this invention, through the designed force-bearing rod, can transmit the mechanical energy generated by rail vibration to the output shaft of the generator through a transmission device, a rotating device, and a gear set, thereby generating electrical energy, thus realizing the function of collecting track vibration energy.

[0008] Preferably, the transmission device includes a first ratchet, a first hollow shaft, a first transmission rod, a first rotating rod, and a first pawl. The first ratchet is fixedly sleeved on the rotating shaft. The first hollow shaft is rotatably connected to one side of one of the support seats, and the rotating shaft is coaxial with the first hollow shaft. One end of the first rotating rod is hinged to the side wall of the hollow shaft, and the other end is hinged to one end of the first transmission rod. The end of the first transmission rod away from the first rotating rod is hinged to the force-bearing rod. The first pawl is supported on one side of the hollow shaft by a first bracket, and the first pawl cooperates with the first ratchet.

[0009] In this technical solution, the hollow shaft is a hollow structure located inside one of the support seats, and the rotating shaft passes through the hollow shaft. In this solution, when the rail vibrates, the rail causes the force-bearing rod to swing up and down. When the force-bearing rod swings downwards, it drives the hollow shaft to rotate counterclockwise via the transmission of the first transmission rod and the first rotating rod. The counterclockwise rotation of the hollow shaft drives the first pawl to rotate counterclockwise. Since the first pawl and the first ratchet are locked in the counterclockwise direction, the first pawl also drives the first ratchet to rotate counterclockwise. The counterclockwise rotation of the first ratchet then drives the rotating shaft to rotate counterclockwise. After the rotating shaft rotates counterclockwise, it transmits power to the generator's main shaft via a gear set, thereby causing the generator to generate electricity. Yes; when the force-bearing rod swings upward, it drives the hollow shaft to rotate clockwise through the transmission of the first transmission rod and the first rotating rod. The clockwise rotation of the hollow shaft drives the first pawl to rotate clockwise. Since the first pawl and the first ratchet are movably connected in the counterclockwise direction, the first pawl will not drive the first ratchet to rotate clockwise, that is, it will not affect the rotational speed of the first ratchet in the counterclockwise direction. Under the action of inertia, the first ratchet continues to rotate counterclockwise. When the force-bearing rod swings downward again, it will drive the first ratchet to rotate counterclockwise again, causing the first ratchet to continuously increase its speed in the counterclockwise direction. This, in turn, causes the rotating shaft to drive the generator main shaft to continuously increase its speed through the gear set, thereby improving the power generation efficiency. In summary, this solution, through the setting of the first ratchet, the first hollow shaft, the first transmission rod, the first rotating rod, and the first pawl, makes the generator's output shaft continuously accelerate in one direction with the vibration of the rail, thus improving the power generation efficiency.

[0010] Preferably, the first support is provided with a first elastic pressure plate, one end of the first elastic pressure plate is connected to the first support, and the other end is pressed against the end of the first pawl away from the first ratchet.

[0011] In this technical solution, the first elastic pressure plate can limit the first pawl and prevent it from loosening.

[0012] Preferably, the transmission device further includes a second ratchet, a second hollow shaft, a second transmission rod, a second rotating rod, and a second pawl. The second ratchet is fixedly sleeved on the rotating shaft. The second hollow shaft is rotatably connected to one side of another support base, and the rotating shaft is coaxial with the second hollow shaft. One end of the second rotating rod is hinged to the side wall of the hollow shaft, and the other end is hinged to one end of the second transmission rod. The end of the second transmission rod away from the second rotating rod is hinged to the force-bearing rod. The second pawl is supported on the side wall of the hollow shaft by a second bracket, and the second pawl cooperates with the second ratchet. The second bracket is provided with a second elastic pressure plate. One end of the second elastic pressure plate is connected to the second bracket, and the other end presses against the end of the second pawl away from the second ratchet.

[0013] In this technical solution, the addition of a second ratchet, a second hollow shaft, a second transmission rod, a second rotating rod, and a second pawl increases the power source that provides power to the rotating shaft, thereby further improving the power generation efficiency.

[0014] Preferably, the first ratchet and the second ratchet are symmetrically arranged on the rotating shaft with the longitudinal section passing through the centerline of the force-bearing rod as the plane of symmetry; the first transmission rod and the first rotating rod are located on both sides of the thickness direction of the force-bearing rod, respectively; and the first transmission rod and the first rotating rod are mirror images of the second transmission rod and the second rotating rod with the longitudinal section passing through the axis of rotation as the plane of symmetry.

[0015] In this technical solution, since the first and second ratchet wheels are arranged in pairs, and since the first transmission rod and the first rotating rod are mirror images of the second transmission rod and the second rotating rod, when the force-bearing rod swings downward, it drives the first hollow shaft and the first pawl to rotate counterclockwise via the first transmission rod and the first rotating rod, which in turn drives the first ratchet wheel to rotate counterclockwise. Meanwhile, the second transmission rod and the second rotating rod drive the second hollow shaft and the second pawl to rotate clockwise. Since the second pawl and the second ratchet wheel are movable in the clockwise direction, the second ratchet wheel will not rotate. That is, when the force-bearing rod swings downward, it drives the rotating shaft to rotate counterclockwise via the first ratchet wheel, which in turn causes the generator main shaft to rotate and generate electrical energy. Similarly, when the force-bearing rod swings upward, the first ratchet wheel will not rotate, while the second ratchet wheel will rotate counterclockwise, which will drive the rotating shaft to continue to accelerate in the counterclockwise direction. In other words, whether the force-bearing rod swings upward or downward, it will accelerate the rotating shaft in the counterclockwise direction, further improving the power generation efficiency. Furthermore, since the various components are symmetrically arranged, the force distribution of the entire device is uniform, and its lifespan is greatly improved.

[0016] Preferably, the gear set includes a driving gear and a driven gear. The driving gear is fixedly mounted on the rotating shaft, and the driven gear is fixedly mounted on the main shaft of the generator. The driving gear and the driven gear mesh with each other.

[0017] In this technical solution, the diameter of the driving gear is larger than that of the driven gear, which increases the rotational speed of the generator main shaft.

[0018] Preferably, it also includes a housing, in which the force-bearing rod, mounting base, generator, rotating device, and transmission device are all housed; and the force-bearing rod, mounting base, generator, rotating device, and transmission device are each in two groups, with the two groups of force-bearing rods, mounting bases, generators, rotating devices, and transmission devices arranged in a centrally symmetrical manner with the longitudinal section passing through the centerline of the housing as the plane of symmetry; and the ends of the force-bearing rods in both groups that are away from the support base extend out of the housing and are connected to a force-bearing plate.

[0019] In this technical solution, the enclosure protects all components. Furthermore, the enclosure has elongated through holes for the force-bearing rods to pass through; the length and width of these through holes are greater than the length and width of the force-bearing rods. Also, since the force-bearing rods, mounting bases, generators, rotating devices, and transmission devices are all housed within the enclosure, and these components are arranged in two symmetrical groups, this power generation device can collect energy generated by the two rails on the track. Additionally, the force is evenly distributed, increasing the overall lifespan of the device.

[0020] Preferably, a spring is provided on the inner wall of the box, with one end of the spring connected to the inner wall of the box and the other end connected to the force-bearing rod.

[0021] In this technical solution, the spring is used to assist the vibration of the force-bearing rod.

[0022] Preferably, the force-bearing rod is a telescopic structure.

[0023] In this technical solution, the force-bearing rod is a telescopic structure, specifically a two-section telescopic structure, where one end of one section slides into the inner cavity of the other section, and several insertion holes are provided on both sections. The length is adjusted by the cooperation of the pins and insertion holes. In this solution, setting the force-bearing rod as a telescopic mechanism facilitates the installation of the entire device. Since the force-bearing plates on both sides of the box need to be installed at the bottom of two steel rails respectively, the distance between the outer ends of the two force-bearing plates is definitely greater than the distance between the inner ends of the two steel rails. Therefore, when installing the power generation device from top to bottom, the two steel rails will obstruct the installation. Therefore, in this solution, setting the force-bearing rod as a telescopic structure can facilitate the installation of the power generation device.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] 1. This invention, through the setting of a force-bearing rod, can transmit the mechanical energy generated by the vibration of the rail to the output shaft of the generator via a transmission device, a rotating device and a gear set, thereby generating electrical energy, and realizing the function of collecting track vibration energy.

[0026] 2. The present invention improves power generation efficiency by setting a first ratchet, a first hollow shaft, a first transmission rod, a first rotating rod, and a first pawl so that the output shaft of the generator continuously accelerates in one direction with the vibration of the rail.

[0027] 3. In this invention, due to the arrangement of the first ratchet, the first hollow shaft, the first transmission rod, the first rotating rod, and the first pawl, the rotating shaft will be accelerated in the counterclockwise direction regardless of whether the force rod swings upward or downward, which further improves the power generation efficiency. Secondly, since the various components are arranged symmetrically, the force distribution of the entire device is uniform, and the lifespan is greatly improved. Attached Figure Description

[0040] The following is combined with Figures 1-7 The present invention will be described in detail below.

[0041] Example

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, this embodiment proposes a vibration energy recovery device, including a force-bearing rod 10, a mounting base, a generator 20, a rotating device, and a transmission device. One end of the force-bearing rod 10 is hinged to the mounting base. The rotating device includes a rotating shaft 30, a support base 11, and a gear set. There are two support bases 11, which are spaced apart below the force-bearing rod 10 along its thickness direction. The two ends of the rotating shaft 30 are rotatably connected to the two support bases 11 respectively, and the rotating shaft 30 is connected to the main shaft 21 of the generator 20 via the gear set. The transmission device drives the force-bearing rod 10 and the rotating shaft 30. When the force-bearing rod 10 swings up and down, it drives the rotating shaft to rotate through the transmission device. It should be noted that when it is necessary to collect the energy generated by track vibration, the entire device is installed between two adjacent sleepers. That is, the mounting base is first placed between two adjacent sleepers, and the end of the force-bearing rod 10 away from the mounting base is installed under the rail. When the rail vibrates, the rail drives the force-bearing rod 10 to swing up and down. After the force-bearing rod 10 swings up and down, the power is transmitted to the rotating shaft 30 through the transmission device to drive the rotating shaft 30 to rotate. After the rotating shaft 30 rotates, the power is transmitted to the main shaft 21 of the generator 20 through the gear set, so that the main shaft 21 of the generator 20 rotates, thereby converting mechanical energy into electrical energy.

[0043] like Figure 4 , Figure 5As shown, in this embodiment, the transmission device includes a first ratchet 60, a first hollow shaft 61, a first transmission rod 62, a first rotating rod 63, and a first pawl 64. The first ratchet 60 is fixedly sleeved on the rotating shaft 30. The first hollow shaft 61 is rotatably connected to one side of one of the support seats 11, and the rotating shaft 30 is coaxial with the first hollow shaft 61. One end of the first rotating rod 63 is hinged to the side wall of the hollow shaft, and the other end is hinged to one end of the first transmission rod 62. The end of the first transmission rod 62 away from the first rotating rod 63 is hinged to the force-bearing rod 10. The first pawl 64 is supported on one side of the hollow shaft by a first bracket 65, and the first pawl 64 cooperates with the first ratchet 60. It should be noted that the hollow shaft is a hollow structure, located inside one of the support seats 11, with the rotating shaft 30 passing through it. In this design, when the rail vibrates, the rail causes the force-bearing rod 10 to swing up and down. When the force-bearing rod 10 swings downward, it drives the hollow shaft to rotate counterclockwise through the transmission of the first transmission rod 62 and the first rotating rod 63. The counterclockwise rotation of the hollow shaft drives the first pawl 64 to rotate counterclockwise. Since the first pawl 64 and the first ratchet 60 are locked in the counterclockwise direction, the first pawl 64 also drives the first ratchet 60 to rotate counterclockwise. The counterclockwise rotation of the first ratchet 60 then drives the rotating shaft 30 to rotate counterclockwise. After the rotating shaft 30 rotates counterclockwise, it transmits power to the main shaft 21 of the generator 20 through the gear set, thereby causing the generator 20 to generate electricity. Yes; when the force-bearing rod 10 swings upward, the force-bearing rod 10 drives the hollow shaft to rotate clockwise through the transmission of the first transmission rod 62 and the first rotating rod 63. The clockwise rotation of the hollow shaft drives the first pawl 64 to rotate clockwise. Since the first pawl 64 and the first ratchet 60 are movably connected in the counterclockwise direction, the first pawl 64 will not drive the first ratchet 60 to rotate clockwise, that is, it will not affect the rotational speed of the first ratchet 60 in the counterclockwise direction. Under the action of inertia, the first ratchet 60 continues to rotate counterclockwise. When the force-bearing rod 10 swings downward again, it will drive the first ratchet 60 to rotate counterclockwise again, so that the first ratchet 60 continuously increases in speed in the counterclockwise direction. In turn, the rotating shaft 30 will drive the main shaft 21 of the generator 20 to continuously increase in speed through the gear set, thereby improving the power generation efficiency. In summary, this solution, through the arrangement of the first ratchet 60, the first hollow shaft 61, the first transmission rod 62, the first rotating rod 63, and the first pawl 64, enables the output shaft of the generator 20 to continuously accelerate in one direction with the vibration of the rail, thereby improving the power generation efficiency.

[0044] like Figure 6 As shown, in this embodiment, the first bracket 65 is provided with a first elastic pressure plate 66. One end of the first elastic pressure plate 66 is connected to the first bracket 65, and the other end presses against the end of the first pawl 64 away from the first ratchet 60. It should be noted that the first elastic pressure plate 66 can limit the first pawl 64 and prevent it from loosening.

[0045] Example 2

[0046] like Figure 5 , Figure 6 , Figure 7 As shown, this embodiment is largely the same as the above embodiment, except that the transmission device further includes a second ratchet, a second hollow shaft 71, a second transmission rod 72, a second rotating rod 73, and a second pawl 70. The second ratchet is fixedly sleeved on the rotating shaft 30. The second hollow shaft 71 is rotatably connected to one side of another support seat 11, and the rotating shaft 30 is coaxial with the second hollow shaft 71. One end of the second rotating rod 73 is hinged to the side wall of the hollow shaft, and the other end is hinged to one end of the second transmission rod 72. The end of the second transmission rod 72 away from the second rotating rod 73 is hinged to the force-bearing rod 10. The second pawl 70 is supported on the side wall of the hollow shaft by a second bracket 75, and the second pawl 70 cooperates with the second ratchet. A second elastic pressure plate 76 is provided on the second bracket 75. One end of the second elastic pressure plate 76 is connected to the second bracket 75, and the other end presses against the end of the second pawl 70 away from the second ratchet. It should be noted that by setting the second ratchet, the second hollow shaft 71, the second transmission rod 72, the second rotating rod 73, and the second pawl 70, the power source providing power to the rotating shaft 30 is increased, further improving the power generation efficiency.

[0047] like Figure 5As shown, in this embodiment, the first ratchet 60 and the second ratchet are symmetrically arranged on the rotating shaft 30 with the longitudinal section passing through the centerline of the force-bearing rod 10 as the plane of symmetry; the first transmission rod 62 and the first rotating rod 63 are located on both sides of the force-bearing rod 10 in the thickness direction; and the first transmission rod 62 and the first rotating rod 63 are mirror images of the second transmission rod 72 and the second rotating rod 73 with the longitudinal section passing through the axis of the rotating shaft 30 as the plane of symmetry. It should be noted that, since the first ratchet 60 and the second ratchet are arranged in pairs, and since the first transmission rod 62 and the first rotating rod 63 are mirror images of the second transmission rod 72 and the second rotating rod 73, when the force rod 10 swings downward, it will drive the first hollow shaft 61 and the first pawl 64 to rotate counterclockwise via the first transmission rod 62 and the first rotating rod 63, thereby driving the first ratchet 60 to rotate counterclockwise. Meanwhile, the second transmission rod 72 and the second rotating rod 73 drive the second hollow shaft 71 and the second pawl 70 to rotate clockwise. Since the second pawl 70 and the second ratchet are movable in the clockwise direction, the second… The ratchet does not rotate. That is, when the force rod 10 swings downward, the first ratchet 60 drives the rotating shaft 30 to rotate counterclockwise, which in turn causes the main shaft 21 of the generator 20 to rotate and generate electricity. Similarly, when the force rod 10 swings upward, the first ratchet 60 does not rotate, but the second ratchet will rotate counterclockwise, which in turn drives the rotating shaft 30 to continue to accelerate in the counterclockwise direction. In other words, no matter whether the force rod 10 swings upward or downward, it will accelerate the rotating shaft 30 in the counterclockwise direction, which further improves the power generation efficiency. Secondly, since the various components are symmetrically arranged, the force distribution of the entire device is uniform, and the lifespan is greatly improved.

[0048] Example 3

[0049] like Figure 4 As shown, this embodiment is largely the same as the previous embodiment, except that the gear set includes a driving gear 50 and a driven gear 51. The driving gear 50 is fixedly mounted on the rotating shaft 30, and the driven gear 51 is fixedly mounted on the main shaft 21 of the generator 20, and the driving gear 50 and the driven gear 51 mesh with each other. It should be noted that the diameter of the driving gear 50 is larger than the diameter of the driven gear 51, which increases the rotational speed of the main shaft 21 of the generator 20.

[0050] Example 4

[0051] like Figure 2As shown, this embodiment is largely the same as the above embodiment, except that it also includes a housing 80. The force-bearing rod 10, mounting base, generator 20, rotating device, and transmission device are all located inside the housing 80. Furthermore, the force-bearing rod 10, mounting base, generator 20, rotating device, and transmission device are each in two sets. The force-bearing rod 10, mounting base, generator 20, rotating device, and transmission device in the two sets are centrally symmetrically distributed with the longitudinal section passing through the centerline of the housing 80 as the plane of symmetry. Moreover, the ends of the force-bearing rods 10 in both sets that are away from the support base 11 extend out of the housing 80 and are connected to the force-bearing plate 12. It should be noted that the enclosure 80 can protect all components. Secondly, the enclosure 80 has elongated through holes through which the force-bearing rod 10 passes, with the length and width of the through holes exceeding the length and width of the force-bearing rod 10. Furthermore, since the force-bearing rod, mounting base, generator 20, rotating device, and transmission device in this application are all housed within the enclosure 80, and the force-bearing rod 10, mounting base, generator 20, rotating device, and transmission device are each in two sets and symmetrically distributed, this power generation device can collect the energy generated by the two rails on the track. Additionally, the force is evenly distributed, increasing the overall lifespan of the device.

[0052] like Figure 2 As shown, in this embodiment, a spring 13 is provided on the inner wall of the housing 80. One end of the spring 13 is connected to the inner wall of the housing 80, and the other end is connected to the force-bearing rod 10. The spring 13 is used to assist the force-bearing rod 10 in vibration.

[0053] Example 5

[0054] This embodiment is largely the same as the above embodiment, except that the force-bearing rod 10 is a telescopic structure. It should be noted that the force-bearing rod 10 is a telescopic structure, specifically a two-section telescopic structure, where one end of one section slides into the inner cavity of the other section, and several insertion holes are provided on both sections. The length is adjusted by the cooperation of the pins and insertion holes. In this solution, making the force-bearing rod 10 a telescopic mechanism facilitates the installation of the entire device. Since the force-bearing plates 12 on both sides of the housing 80 need to be installed at the bottom of two steel rails respectively, the distance between the outer ends of the two force-bearing plates 12 is definitely greater than the distance between the inner ends of the two steel rails. Therefore, when installing the power generation device from top to bottom, the two steel rails will obstruct the installation. Therefore, in this solution, making the force-bearing rod 10 a telescopic structure facilitates the installation of the power generation device.

[0055] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
