Description

Technical Field

[0001] This utility model belongs to the field of energy harvesting technology, specifically relating to a large articulated bus road energy harvesting system. Background Technology

[0002] Road sensing equipment is a key device that utilizes advanced technology to monitor road conditions in real time, primarily consisting of pavement condition sensors. These sensors can measure various pavement parameters, such as pavement temperature, condition (dry, wet, waterlogged, etc.), water film height, ice thickness, and snow thickness, providing management personnel with a reliable data source. Pavement condition sensors are widely used in various traffic scenarios, including highways, urban roads, bridges, and tunnels. They can also be integrated with intelligent traffic management systems to achieve real-time monitoring and early warning of road conditions, ensuring traffic safety.

[0003] Road sensing devices primarily rely on traditional batteries or urban power grids for power. Traditional battery power requires battery replacement when depleted, while urban power grids offer stable and reliable 220V connections, but their use is limited by the need to consider the reliability and stability of the power supply lines. Road sensing devices suffer from problems such as difficult power supply, high cost, complex maintenance, and environmental pollution. Therefore, how to reliably and conveniently power these road sensing devices has become an urgent problem to be solved.

[0004] Against this backdrop, because vehicles travel on roads, gaps exist between their various structures, making them prone to vibration when encountering uneven road surfaces or impacts, especially large vehicles such as articulated buses and large trailers. These vehicles generate vibrations during operation, leading to energy loss. This vibration not only damages the vehicle but also exerts impact forces on the road surface, causing fatigue of the road materials and accelerating road deterioration and aging. Over time, this results in cracks and potholes in the road surface, affecting the road's lifespan and driving safety.

[0005] Because these vibrations generate significant energy, effectively utilizing this vibrational energy would have substantial practical benefits for resource conservation. Therefore, using the mechanical energy generated by these vibrations to generate electricity and power road sensing devices provides researchers with a simple, stable, and efficient solution for powering these devices. Thus, developing an energy harvesting system capable of utilizing vehicle vibration energy is of great importance. Utility Model Content

[0006] This utility model discloses a large articulated bus road energy harvesting system, which aims to solve the technical problem of urgently needing to develop a road energy harvesting system that utilizes the energy of vehicle vibration to generate electricity and power road sensing equipment.

[0007] To solve the aforementioned technical problems, the present invention adopts the following technical solution:

[0008] A large articulated bus road energy harvesting system includes an input module, a conversion module, and a power generation module connected in sequence.

[0009] The input module includes a fixed frame, a guide mechanism slidably connected to the fixed frame, the guide mechanism contacting the vehicle and receiving vehicle vibrations, an elastic energy storage device on the guide mechanism, the elastic energy storage device being disposed between the fixed frame and the guide mechanism, and the guide mechanism being connected to the conversion module via a first connecting device;

[0010] The conversion module includes a rotating mechanism that converts the linear motion of the guide mechanism into rotational motion. The rotating mechanism is connected to the power generation module, which generates electricity through electromagnetic induction by rotating the rotating mechanism.

[0011] With this technical solution, the system is installed below the road. When a vehicle passes over the system, the vibration of the vehicle itself and the impact of the vehicle on the road cause vibration and impact. The guide mechanism can receive this vibration and impact generated by the vehicle passing over and respond quickly to the vibration of the vehicle, so that the guide mechanism moves downward along the fixed frame. The guide mechanism transmits this linear motion to the conversion module through the first connecting device. The rotation mechanism of the conversion module converts the linear motion into rotational motion, thereby transferring mechanical energy from the input module to the conversion module. In the power generation module, the power generation module uses this rotational motion to cut the magnetic field lines, generate electromagnetic induction to generate electricity, and finally convert mechanical energy into electrical energy.

[0012] During this process, the elastic energy storage device stores a portion of the mechanical energy generated by vibration, which works in conjunction with the conversion device. After the vehicle leaves the system, it provides the conversion device with the kinetic energy to rotate the rotating mechanism in the forward direction, enabling the system to generate electricity even during reset, thus improving power generation efficiency. Simultaneously, it allows the guide mechanism to return to its original position to receive the next vibration. Therefore, during the vibration and recovery process of the guide mechanism, some mechanical energy is directly transferred to the conversion device through the guide mechanism, while another portion of the mechanical energy, during the guide mechanism's recovery process, is transmitted to the conversion device again via the elastic energy storage device. This achieves continuous energy transfer and efficient energy conversion within the system, improving energy utilization.

[0013] The rotating mechanism includes a gear set, which includes a first gear connected to a first connecting device. The first gear meshes with a second gear. A connecting rod is provided through the center of the second gear. A first bevel gear and a second bevel gear are respectively provided on both sides of the second gear on the connecting rod. The first bevel gear and the second bevel gear mesh with a third bevel gear. The third bevel gear is connected to a drive shaft, which is connected to a power generation module. The first bevel gear and the second bevel gear are respectively provided with first one-way bearings with opposite rotation directions.

[0014] By adopting this technical solution, the vibration energy received by the guide mechanism is converted and transmitted through the gear set. On the one hand, the guide mechanism achieves a zero pressure angle setting through the first connecting device and the first gear, so that the direction of the driving force is always the same as the rotation direction of the first gear during the conversion between linear and rotary motion, which can reduce energy loss in this process and achieve the purpose of efficient energy conversion. On the other hand, the meshing transmission between gears is more precise than other methods, and the operation is smoother, making the system more stable during use.

[0015] Meanwhile, first one-way bearings with opposite rotation directions are respectively set on the first bevel gear and the second bevel gear. This works in conjunction with the guide mechanism and the elastic energy storage device. During the process of the guide mechanism driving the first gear to rotate forward and backward, the first bevel gear and the second bevel gear mesh with the third bevel gear respectively, so that the third bevel gear always rotates in one direction. For a power generation device that generates electricity by cutting magnetic induction lines, the current generated by this consistent cutting method is more continuous and stable.

[0016] The power generation module includes a generator, which is a three-phase AC generator, and the rotating mechanism is connected to the rotating main shaft of the generator.

[0017] After adopting this technical solution, the three-phase AC generator has the advantages of high efficiency, stable output, compact structure, and high reliability. In this system, the three-phase AC generator can effectively convert mechanical energy into electrical energy and provide a stable three-phase power output, which can charge the energy storage device.

[0018] An enhancement module is provided between the conversion module and the power generation module. The enhancement module includes a planetary gear accelerator. One end of the planetary gear accelerator is connected to a rotating mechanism via a coupling, and the other end is connected to an inertial flywheel via a second one-way bearing. The inertial flywheel is connected to a generator via a coupling. The transmission ratio of the planetary gear accelerator is 0.7-0.9.

[0019] After adopting this technical solution, the planetary gear accelerator can increase the rotational speed transmitted from the gear set drive shaft to the planetary gear accelerator, thereby increasing the rotational kinetic energy. The planetary accelerator then transmits the rotational kinetic energy to the inertial flywheel through the second one-way bearing, causing the inertial flywheel to rotate. The inertial flywheel stores part of the rotational kinetic energy and also drives the main shaft of the generator to rotate, transmitting the rotational kinetic energy to the power generation module. This cuts the magnetic field lines in the power generation module, generating electromagnetic induction power.

[0020] The planetary gear accelerator achieves the transmission speed increase of this system, and the inertial flywheel stores kinetic energy. The combination of the planetary gear accelerator and the inertial flywheel improves the power generation efficiency, increases the amount of electricity generated per unit time, and can power the road sensing equipment, saving the cost of powering the road sensing equipment.

[0021] The second one-way bearing is designed to avoid the influence of the accelerator's internal damping on the flywheel's rotation. When driven by external excitation, the second one-way bearing is engaged, and the externally input energy is normally transferred to the flywheel and generator. When driven by the inertial flywheel, the second one-way bearing disengages, and the inertial flywheel only drives the generator to continue rotating, stabilizing the generator's speed change and improving output stability.

[0022] The guiding mechanism is a guide rod, and an upper top plate is provided on the top of the guide rod. The elastic energy storage device is located above the fixed frame and between the fixed frame and the upper top plate.

[0023] After adopting this technical solution, the top plate can protect the guide mechanism on the one hand, and the reaction range of the top plate to withstand more vibration and pressure is larger and wider. On the other hand, it can restrict the elastic energy storage device, so that the extension points at both ends of the elastic energy storage device can only be on the fixed frame and the top plate, making the elastic energy storage device more stable during use, thereby improving the stability of the device.

[0024] The fixed frame is equipped with a linear bearing that cooperates with the guide mechanism.

[0025] By adopting this technical solution, the linear bearing can reduce the friction between the guide mechanism and the fixed frame, transforming it into friction between the guide mechanism and the linear bearing. This protects the guide mechanism, reduces wear, and extends its service life.

[0026] The first connecting assembly includes a roller, and the guiding mechanism is connected to the rotating mechanism via the roller. The rotating mechanism has a transverse groove that mates with the roller, and the roller is placed in the transverse groove, allowing the rotating mechanism to rotate counterclockwise or clockwise. With this technical solution, the friction between the roller and the transverse groove is relatively large, enabling the roller to move upward or downward relative to the transverse groove under the action of the guiding mechanism, thereby driving the first gear to rotate in the forward or reverse direction.

[0027] Meanwhile, the top plate, guide rod, elastic energy storage mechanism, and linear bearing constitute a four-bar linkage. Its main function is to convert reciprocating linear motion into rotational motion through cooperation with rollers and the first gear. The design of this mechanism utilizes its dead point position, which allows the system to continue moving through inertia after the external excitation disappears, thereby improving energy conversion efficiency.

[0028] The power generation module is connected to a storage module, which includes a supercapacitor. The supercapacitor is connected to the power generation module through a rectifier circuit.

[0029] After adopting this technical solution, the current generated by the power generation module is rectified by the rectifier circuit and then sent to the supercapacitor for storage. This charging of the supercapacitor improves the quality and stability of the stored current. The supercapacitor can charge road sensing equipment, realizing the effective utilization and conversion of energy.

[0030] The input module, conversion module, and power generation module are all housed within the enclosure, and the top of the guide mechanism is parallel to the top surface of the enclosure.

[0031] By adopting this technical solution, the enclosure can protect the system, extend its service life, generate electricity effectively, and improve economic efficiency; while placing the guide mechanism on the top surface of the enclosure can improve the sensitivity to vibrations generated when vehicles pass by, thereby improving the system's sensitivity.

[0032] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0033] (1) By using input modules, conversion modules, etc., the mechanical energy of vehicle vibration is converted into electrical energy, so as to realize the effective conversion and utilization of energy and improve the energy conversion and utilization efficiency.

[0034] (2) The use of gear sets and the like reduces energy loss on the one hand and makes the power transmission more precise on the other.

[0035] (3) Use a three-phase AC generator, etc. A three-phase AC generator can effectively convert mechanical energy into electrical energy and can provide a stable three-phase power output, which can charge the energy storage device.

[0036] (4) By using planetary gear accelerators, inertial flywheels, etc., the power generation efficiency is improved, the amount of electricity generated per unit time is increased, and the power supply for road sensing equipment is provided, saving the cost of powering road sensing equipment.

[0037] (5) The second one-way bearing is adopted. The setting of the second one-way bearing avoids the influence of the internal damping of the accelerator on the rotation of the flywheel. When driven by external excitation, the second one-way bearing is in the meshing state, and the external input energy is normally transferred to the flywheel and the generator. When driven by the inertial flywheel, the second one-way bearing is disengaged, and the inertial flywheel only drives the generator to continue to rotate, stabilizing the generator speed change and improving the output stability.

[0038] (6) Using linear bearings, etc. The setting of linear bearings can reduce the friction between the guide mechanism and the fixed frame, and transform it into the friction between the guide mechanism and the linear bearing. This can protect the guide mechanism, reduce the wear on the guide mechanism, and extend the service life of the guide mechanism.

[0039] (7) Using a box or similar structure can protect the system, extend its service life, generate electricity effectively, and improve economic efficiency; while setting the guide mechanism on the top surface of the box can improve the sensitivity to vibrations generated when vehicles pass by, thereby improving the sensitivity of the system.

Therefore, they should not be construed as limitations on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0049] The following is combined Figures 1-4 This utility model will be described in detail.

[0050] A large articulated bus road energy harvesting system, such as Figures 1-4 As shown, it includes an input module 2, a conversion module, and a power generation module connected in sequence;

[0051] The input module 2 includes a fixed frame, a guide mechanism slidably connected to the fixed frame, the guide mechanism contacting the vehicle and receiving vehicle vibrations, an elastic energy storage device on the guide mechanism, the elastic energy storage device being disposed between the fixed frame and the guide mechanism, and the guide mechanism being connected to the conversion module through a first connecting device;

[0052] The conversion module includes a rotating mechanism that converts the linear motion of the guide mechanism into rotational motion. The rotating mechanism is connected to the power generation module, which generates electricity through electromagnetic induction by rotating the rotating mechanism.

[0053] In this embodiment, the fixing frame is made of stainless steel, and the surface of the stainless steel can also be coated with a layer of anti-corrosion paint to further increase the rust resistance of the fixing frame.

[0054] In this embodiment, the elastic energy storage device is a spring 202.

[0055] In this embodiment, the guiding mechanism is also made of stainless steel.

[0056] This system is installed below the road. When a vehicle passes over the system, the vibration of the vehicle itself and the impact of the vehicle on the road cause vibration and impact. The guide mechanism can receive this vibration and impact generated by the vehicle passing over it and respond quickly to the vibration of the vehicle. The guide mechanism moves downward along the fixed frame. The guide mechanism transmits this linear motion to the conversion module through the first connecting device. The rotation mechanism of the conversion module converts the linear motion into rotational motion, thereby transferring mechanical energy from the input module 2 to the conversion module. In the power generation module, the power generation module uses this rotational motion to cut the magnetic field lines, generate electromagnetic induction to generate electricity, and finally convert mechanical energy into electrical energy.

[0057] During this process, the elastic energy storage device stores a portion of the mechanical energy generated by vibration, which works in conjunction with the conversion device. After the vehicle leaves the system, it provides the conversion device with the kinetic energy to rotate the rotating mechanism in the forward direction, enabling the system to generate electricity even during reset, thus improving power generation efficiency. Simultaneously, it allows the guide mechanism to return to its original position to receive the next vibration. Therefore, during the vibration and recovery process of the guide mechanism, some mechanical energy is directly transferred to the conversion device through the guide mechanism, while another portion of the mechanical energy, during the guide mechanism's recovery process, is transmitted to the conversion device again via the elastic energy storage device. This achieves continuous energy transfer and efficient energy conversion within the system, improving energy utilization.

[0058] In this embodiment, the rotating mechanism includes a gear set 3, which includes a first gear 301 connected to a first connecting device. The first gear 301 meshes with a second gear 302. A connecting rod 305 is provided through the center of the second gear 302. A first bevel gear 303 and a second bevel gear 304 are respectively provided on both sides of the second gear 302 on the connecting rod 305. The first bevel gear 303 and the second bevel gear 304 mesh with a third bevel gear 307. The third bevel gear 307 is connected to a drive shaft 308, which is connected to a power generation module. The first bevel gear 303 and the second bevel gear 304 are respectively provided with first one-way bearings 306 with opposite rotation directions.

[0059] In this embodiment, the gears of the gear set 3 are all made of forged steel, which can adapt to high-strength conditions.

[0060] In this embodiment, the first gear 301 has 34 teeth, the second gear 302 has 14 teeth, and the transmission ratio between them is 2.34.

[0061] In this embodiment, the connecting rod 305 is connected to the second gear 302 by a key.

[0062] In this embodiment, the first bevel gear 303 and the second bevel gear 304 are also connected to the connecting rod 305 via a key. In other embodiments, the connecting rod 305 can also be connected to the second gear 302, the first bevel gear 303, and the second bevel gear 304 by welding.

[0063] In this embodiment, the connecting rod 305 is also made of forged steel.

[0064] In this embodiment, the drive shaft 308 is driven by the third bevel gear 307 via a key. In other embodiments, a one-way bearing can be used to ensure that the drive shaft 308 can only rotate in one direction.

[0065] In this embodiment, the first bevel gear 303, the second bevel gear 304 and the third bevel gear 307 have the same module and number of teeth, with a module of 1 and a number of teeth of 30. The diameters of the first bevel gear 303, the second bevel gear 304 and the third bevel gear 307 are also the same, with a diameter range of 25-35cm, preferably 30cm.

[0066] In this embodiment, the dimensions of the first one-way bearing 306 are 10x14x12mm. Both the first one-way bearing 306 and the second one-way bearing 6 in this embodiment are existing technologies. A one-way bearing, also called an overrunning clutch, is a type of bearing that can rotate freely in one direction but is locked in the other. The metal housing of a one-way bearing contains many rollers, needle rollers, or balls, and the shape of its rolling seat (cavity) allows it to roll only in one direction, while generating significant resistance in the other direction. The first one-way bearing 306 plays a crucial role in the conversion module, converting the input bidirectional linear motion into unidirectional rotary motion, thus improving energy conversion efficiency.

[0067] The vibration energy received by the guide mechanism is converted and transmitted through the gear set 3. On the one hand, the guide mechanism achieves a zero pressure angle setting through the first connecting device and the first gear 301, so that the direction of the driving force is always the same as the rotation direction of the first gear 301 during the conversion between linear and rotary motion, which can reduce energy loss in this process and achieve the purpose of efficient energy conversion. On the other hand, the meshing transmission between gears is more precise than other methods, and the operation is smoother, making the system more stable during use.

[0068] Meanwhile, first one-way bearings 306 with opposite rotation directions are respectively provided on the first bevel gear 303 and the second bevel gear 304. This works in conjunction with the guide mechanism and the elastic energy storage device. During the process of the guide mechanism driving the first gear 301 to rotate forward and backward, the first bevel gear 303 and the second bevel gear 304 mesh with the third bevel gear 307 respectively, so that the third bevel gear 307 always rotates in one direction. For a power generation device that generates electricity by cutting magnetic induction lines, the current generated by this consistent cutting method is more continuous and stable.

[0069] In this embodiment, the power generation module includes a generator 8, which is a three-phase AC generator 8, and the rotating mechanism is connected to the rotating main shaft of the generator 8.

[0070] The three-phase AC generator 8 has advantages such as high efficiency, stable output, compact structure, and high reliability. In this system, the three-phase AC generator 8 can effectively convert mechanical energy into electrical energy and provide a stable three-phase power output, which can charge the energy storage device. In other embodiments, a single-phase AC generator 8 may also be used.

[0071] In this embodiment, an enhancement module is provided between the conversion module and the power generation module. The enhancement module includes a planetary gear accelerator 5. One end of the planetary gear accelerator 5 is connected to a rotating mechanism via a coupling 4, and the other end is connected to an inertial flywheel 7 via a second one-way bearing 6. The inertial flywheel 7 is connected to a generator 8 via a coupling 4. The transmission ratio of the planetary gear accelerator 5 is 0.7-0.9.

[0072] In this embodiment, the transmission ratio of the planetary gear accelerator 5 is preferably 0.8, which can increase the kinetic energy of the rotating mechanism and transmit it to the inertial flywheel 7.

[0073] In this embodiment, the planetary gear accelerator 5 is a prior art device that uses a planetary gear mechanism to achieve speed change. The planetary gear mechanism mainly consists of a sun gear, planet gears and an external gear ring. The planetary gears can not only rotate on their own axis (rotation) but also rotate around the axes of other gears (revolution), thereby changing the transmission ratio.

[0074] In this embodiment, the inner diameter of the flywheel is 25cm.

[0075] In this embodiment, the inertial flywheel 7 is connected to the rotating main shaft of the generator 8 via a coupling 4.

[0076] In this embodiment, the second one-way bearing 6 and the first one-way bearing 306 adopt the same structure and principle, both being existing technologies. The one-way bearing includes an outer ring, an inner ring, and rollers, which can be separated and engaged. Specifically, when engaged: when an external power (downward or upward) drives the input shaft, the rotational motion of the input shaft is transmitted to the rollers through the inner ring of the one-way bearing. The rollers roll in the raceway, and due to the wedge effect between the rollers and the outer ring, the rollers are pressed against the raceway of the outer ring, thus forming a mechanical connection between the inner and outer rings. At this time, the one-way bearing is in an engaged state, and power is transmitted. When disengaged: when the external power disappears or the input shaft stops rotating, the rollers inside the one-way bearing disengage from the raceway of the outer ring due to centrifugal force. At this time, the mechanical connection between the inner and outer rings is severed, and power transmission is interrupted. Therefore, the second one-way bearing 6 engages when there is an external power input and disengages when there is no external power input.

[0077] In this embodiment, the inertial flywheel 7 is a mechanical device capable of storing energy. It typically consists of a rotating disk that can rotate at high speed and store and release energy through the inertia of rotation.

[0078] The planetary gear accelerator 5 increases the rotational speed transmitted from the gear set 3 drive shaft 308 to the planetary gear accelerator 5, thereby increasing the rotational kinetic energy. The planetary accelerator then transmits the rotational kinetic energy to the inertial flywheel 7 through the second one-way bearing 6, causing the inertial flywheel 7 to rotate. The inertial flywheel 7 stores part of the rotational kinetic energy and also drives the main shaft of the generator 8 to rotate, transmitting the rotational kinetic energy to the power generation module. This cuts the magnetic field lines in the power generation module, generating electromagnetic induction power.

[0079] The planetary gear accelerator 5 achieves the transmission speed increase of this system, and the inertial flywheel 7 stores kinetic energy. The arrangement of the planetary gear accelerator 5 and the inertial flywheel 7 improves the power generation efficiency, increases the amount of electricity generated per unit time, and can power the road sensing equipment, saving the cost of powering the road sensing equipment.

[0080] The second one-way bearing 6 is designed to avoid the influence of the internal damping of the accelerator on the rotation of the flywheel. When driven by external excitation, the second one-way bearing 6 is engaged, and the energy input from the outside is normally transferred to the flywheel and the generator 8. When driven by the inertial flywheel 7, the second one-way bearing 6 is disengaged, and the inertial flywheel 7 only drives the generator 8 to continue rotating, stabilizing the speed change of the generator 8 and improving the output stability.

[0081] In this embodiment, the guiding mechanism is a guide rod 204, and an upper top plate 201 is provided on the top of the guide rod 204. The elastic energy storage device is arranged above the fixed frame and between the fixed frame and the upper top plate 201.

[0082] In this embodiment, the top plate 201 is made of stainless steel.

[0083] In this embodiment, the upper top plate 201 and the guide mechanism are integrally formed by welding.

[0084] The top plate 201 serves two purposes: firstly, it protects the guide mechanism, allowing it to withstand greater vibration and pressure over a wider range; secondly, it restricts the elastic energy storage device, ensuring that the extension and retraction points at both ends of the device are limited to the fixed frame and the top plate 201, making the device more stable during use and thus improving the overall stability of the device.

[0085] In this embodiment, the fixed frame is provided with a linear bearing 203 that cooperates with the guide mechanism.

[0086] In this embodiment, the linear bearing 203 is mounted on the fixed frame via a threaded connection.

[0087] The linear bearing 203 reduces the friction between the guide mechanism and the fixed frame, transforming it into friction between the guide mechanism and the linear bearing 203. This protects the guide mechanism, reduces wear, and extends its service life.

[0088] In this embodiment, the first connecting device includes a roller 205, the guiding mechanism is connected to the rotating mechanism through the roller 205, the rotating mechanism is provided with a transverse groove that cooperates with the roller 205, the roller 205 is placed in the transverse groove and can make the rotating mechanism rotate counterclockwise or clockwise.

[0089] In this embodiment, as Figure 3 As shown, there are two guide rods 204, and the roller 205 is a round rod structure. The two guide rods 204 are connected by the roller 205, and the first gear 301 is located in the middle of the two guide rods 204.

[0090] In summary, the transverse groove is a square groove that is opened laterally on the plane of the first gear 301.

[0091] In this embodiment, the transverse groove is integrally formed with the first gear 301.

[0092] The roller 205 has a large frictional force with the transverse groove, which allows the roller 205 to move upward or downward relative to the transverse groove under the action of the guide rod 204, thereby driving the first gear 301 to rotate in the forward or reverse direction.

[0093] Meanwhile, the upper plate 201, guide rod 204, elastic energy storage mechanism, and linear bearing 203 constitute a four-bar linkage. Its main function is to convert reciprocating linear motion into rotational motion through cooperation with roller 205 and first gear 301. The design of this mechanism utilizes its dead point position, which allows the system to continue to maintain motion through inertia after the external excitation disappears, thereby improving energy conversion efficiency.

[0094] In this embodiment, the power generation module is connected to a storage module, and the storage module includes a supercapacitor. The supercapacitor is connected to the power generation module through a rectifier circuit.

[0095] In this embodiment, the rectifier circuit is a diode bridge rectifier circuit.

[0096] In this embodiment, the supercapacitor (also known as an electrochemical capacitor, gold capacitor, or farad capacitor) is an electrochemical element that stores electrical energy through a polarized electrolyte. Its energy storage process involves no chemical reaction; reversible charging and discharging is achieved solely through physical charge separation. The supercapacitor comprises a double-layer capacitor and a pseudocapacitor. The double-layer capacitor stores energy through a charge-opposition layer (only 0.3–0.8 nanometers thick) formed at the interface between the electrode (e.g., activated carbon) and the electrolyte, without any chemical reaction. The pseudocapacitor stores charge through redox reactions on the surface of the electrode material (e.g., metal oxide), exhibiting Faraday charge transfer characteristics. The supercapacitor in this embodiment is a hybrid container, resistant to extreme temperatures, and has a cycle life far exceeding that of a battery.

[0097] The current generated by the power generation module is rectified by the rectifier circuit and then sent to the supercapacitor for storage. Charging the supercapacitor improves the quality and stability of the stored current. The supercapacitor can charge road sensing equipment, realizing the effective utilization and conversion of energy.

[0098] In this embodiment, the input module 2, the conversion module, and the power generation module are all housed in the housing 1, and the top of the guide mechanism is parallel to the top surface of the housing 1.

[0099] In this embodiment, the box body 1 includes six panels: top, bottom, left, right, front, and back. The panels are detachably connected by aluminum profiles 101 and bolts. The fixing frame is connected to the bottom of the box body 1 by a support rod, which is threaded to the box body 1. The top plate 201 overlaps with the top plate of the box body 1, and the box body 1 can overlap with the road surface.

[0100] The enclosure 1 can protect the system, extend its service life, generate electricity effectively, and improve economic efficiency; while setting the guide mechanism on the top surface of the enclosure 1 can improve the sensitivity to vibrations generated when vehicles pass by, thereby improving the sensitivity of the system.

[0101] In this embodiment, the efficiency of the guide rod 204 in transferring energy to the gear set 3 is 90%, the efficiency of the gear set 3 in transferring energy to the planetary gear accelerator 5 is 95%, the efficiency of the planetary gear accelerator 5 in transferring energy to the inertial wheel 7 is 94%, and the efficiency of the inertial flywheel 7 in transferring energy to the generator 8 is 92%. For example, when a medium-sized truck with a load capacity of 10 tons passes by, it will generate approximately 500 joules of mechanical energy. After being transferred through the guide rod 204, gear set 3, and planetary gear accelerator 5, it will ultimately generate approximately 370.2 joules of energy. The overall kinetic energy transmission loss is small, which is beneficial for the conversion of mechanical energy and electrical energy and increases the total amount of power generated.

[0102] The specific method of using this utility model is as follows:

[0103] Reference Figures 1-4When using this device, it is first buried under the road, with the top surface parallel to the road surface. When a car passes by, the car will exert pressure on the top plate 201. Under the action of the car pressure, the guide rod 204 moves downward in the linear bearing 203. Part of the pressure is transmitted to the first gear 301 through the roller 205 at the bottom of the guide rod 204. The roller 205 rolls in the transverse groove of the first gear 301, thereby driving the first gear 301 to rotate counterclockwise. The other part is stored in the spring 202 on the guide rod 204. When the car drives away, the spring 202 is released, driving the guide mechanism to rise in the linear bearing 203. The roller 205 rolls in the transverse groove again, driving the first gear 301 to rotate clockwise.

[0104] When the first gear 301 rotates counterclockwise, it meshes with the second gear 302. The second gear 302 drives the first bevel gear 303 to rotate, and the first bevel gear 303 meshes with the third bevel gear 307, causing the drive shaft 308 connected to the third bevel gear 307 to rotate. The drive shaft 308 transmits power to the planetary gear accelerator 5 through the coupling 4. The planetary gear accelerator 5 transmits power to the inertial flywheel 7 through the coupling 4. The inertial flywheel 7 transmits power to the main shaft of the generator 8 through the coupling 4. Electromagnetic induction is generated by cutting the magnetic field lines of the three-phase AC generator 8 to generate electricity. The generated current is rectified by a diode rectifier circuit and then sent to a supercapacitor for storage. The supercapacitor is connected to the road sensing equipment to supply power to it.

[0105] However, when the first gear 301 rotates clockwise, the second bevel gear 304 and the first one-way bearing 306 connected to the second bevel gear 304 provide power in the same direction as the first bevel gear 303, and the subsequent power transmission is carried out in accordance with the above process to generate electricity.

[0106] A second one-way bearing 6 is installed between the inertial flywheel 7 and the generator 8. The second one-way bearing 6 avoids the influence of the internal damping of the accelerator on the rotation of the flywheel. When driven by external excitation, the second one-way bearing 6 is in the meshing state, and the externally input energy is normally transferred to the inertial flywheel 7 and the generator 8. When driven by the inertial flywheel 7, the second one-way bearing 6 is disengaged, and the flywheel only drives the generator 8 to continue rotating, stabilizing the speed change of the generator 8 and improving the output stability.

[0107] The above description of the disclosed embodiments enables those skilled in the art to make or use the present 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 present invention. Therefore, the present 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.
