Description

ENERGY HARVESTING FROM SPEED REDUCERS DESIGNED TO GENERATEELECTRICITY FROM SPEED-REDUCING VEHICLESTECHNICAL FIELD

[0001] The present disclosure generally relates to a speed reducer designed to generate electricity by harvesting kinetic energy of speed-reducing vehicles, and more particularly, relates to an energy harvester that converts harvested kinetic energy of speed-reducing vehicles into electric power for transferring to grid.BACKGROUND ART

[0002] As the global population continues to surge and industries evolve, the demand for electricity has reached unprecedented levels. Electricity has become a fundamental pillar of modem civilization, powering everything from homes and businesses to transportation and communication systems. The increasing reliance on electronic devices, coupled with the expansion of urban areas and industrialization, has amplified the need for reliable and sustainable sources of power. Meeting this escalating demand is paramount to ensuring continued economic growth, social stability, and technological advancement.

[0003] While the focus on traditional power generation methods like fossil fuels and nuclear energy remains significant, there is a growing recognition of the importance of exploring alternative sources of electric power generation. One such area of exploration lies in the infrastructure that supports our transportation networks. Roads, in particular, play a crucial role in facilitating the movement of goods and people. However, beyond their primary function, roads also present an untapped opportunity for energy harvesting. Road bumpers, designed to enhance safety by mitigating vehicular collisions and regulating traffic flow, have the potential to harness kinetic energy and convert it into electricity, thereby contributing to sustainable energy production.

[0004] Road bumpers, traditionally constructed from materials like concrete or metal, are being reimagined to serve a dual purpose: enhancing road safety while simultaneously generating electricity. Various innovative technologies have been developed to integrate energyharvesting mechanisms into these bumpers. Kinetic energy generated by passing vehicles is captured through mechanisms such as piezoelectric materials, electromagnetic induction, or hydraulic systems embedded within the bumpers. However, while these energy-harvesting roadbumpers hold promise for sustainable electricity generation, they also present challenges and limitations. Issues such as durability, maintenance requirements, and cost-effectiveness need to be addressed to ensure the widespread adoption and viability of these technologies in real- world applications.

[0005] There are many systems developed for the purpose of producing electricity using deceleration strips. For example, Peng Caiwang Tan XingbinZhang Xiuli presented a patent on “A kind of intelligent road deceleration strip” (CN206529715U). Peng Caiwang Tan XingbinZhang Xiuli created an intelligent road deceleration strip featuring an embedded system, an intelligent speed-measuring system, and an automatic lifting system. The speedmeasuring system includes a camera to detect vehicle speed, while the lifting system comprises a hydraulic jack and solenoid directional control valve, all connected to the embedded system. This setup allows the deceleration strip to automatically adjust the height of the speed bump based on vehicle speed, ensuring a smoother, quieter ride for slow-moving vehicles. Additionally, it can convert vibration energy to power road equipment, enhancing energy efficiency and environmental protection. Zhao Xingyang presented a patent on “A kind of liftable deceleration strip for power generation” (CN206346130U). Zhao Xingyang developed a liftable deceleration strip for power generation. The liftable deceleration strip system includes a housing cell body with a bolted rubber protection band and a bearing base that slides within the housing. A dividing plate fixed to the housing supports a hydraulic drive cylinder, which connects to a hydraulic push rod. This rod is linked to the bearing base, allowing the hydraulic drive cylinder to lift the deceleration strip. The strip can switch between hard and soft states, reducing mechanical shock at low speeds and minimizing vehicle damage. Additionally, the system converts kinetic energy into electrical energy through a change-speed gearing mechanism, promoting energy regeneration. Both the Intelligent Road Deceleration Strip and the liftable Deceleration Strip for Power Generation have drawbacks. The Intelligent Strip is complex and costly to maintain, with potential reliability issues and weather sensitivity. The liftable Strip introduces mechanical complexity and installation challenges, with concerns about energy efficiency, durability, and environmental impact due to hydraulic systems.

[0006] There is, therefore, a need for an efficient, reliable, and durable speed reducer for producing electricity. There is further a need for a cost-effective speed reducer to generate electricity from kinetic energy of speed-reducing vehicles.SUMMARY OF THE DISCLOSURE
