摘要
传统化石能源的过度使用加剧了资源枯竭和环境污染问题,推动能源转型,实现能源体系的清洁、高效和可持续发展,对于应对气候变化、保障能源安全、促进经济可持续发展具有重要意义。针对重力势能的捕获利用存在转换效率低、电能转换不稳定等现状,设计了一种新型的重力势能捕获系统,通过捕获物料在下落时释放的重力势能产生电能。主要介绍了该系统的结构设计和工作原理,重点研究了重力势能捕获和可控机械能回收的设计方案的实用性;利用SolidWorks开展相关运动仿真,当散状物料推动链轮的转速为15r/min时,获得了捕获系统的重力势能输出功率以及电能收集装置的转速、转矩以及电能输出功率随时间的变化曲线;在调速电机的补偿作用下,电能输出功率维持在123 W附近,重力势能捕获装置的运行平稳安全。仿真结果表明了该系统的创新性和有效性,对提高机械余能回收及再利用的研究具有一定的理论意义。
The excessive use of traditional fossil fuels has exacerbated resource depletion and environmental pollution.Promoting energy transition to achieve a clean,efficient,and sustainable energy system is crucial for addressing climate change,ensuring energy security,and fostering sustainable economic development.To address the current challenges of low conversion efficiency and unstable power generation in harnessing gravitational potential energy,a novel gravitational potential energy capture system has been designed.This system generates electricity by capturing the gravitational potential energy released during the descent of bulk materials.This paper primarily introduces the structural design and working principle of the system,focusing on the practicality of the design scheme for gravity potential energy capture and controllable mechanical energy recovery.Using SolidWorks for motion simulation,when bulk materials drive the sprocket at 15 r/min,the system’s gravity potential energy output power,along with the speed,torque,and electrical output power of the energy collection device,were obtained as time-varying curves.With the compensating effect of the variable-speed motor,the output power was maintained around 123 W,ensuring stable and safe operation of the gravitational potential energy capture device.Simulation results demonstrate the innovation and effectiveness of this system,contributing theoretical significance to research on enhancing the recovery and reuse of mechanical residual energy.
