Description

technical field [0001] The invention relates to a wheel-rail vibration power generation and energy storage system, in particular to a mechanical energy power generation and storage system utilizing trains passing through the wheel-rail. Background technique [0002] The energy crisis is one of the most concerned issues in the world today. [0003] my country is one of the few major railway countries in the world, with a total railway mileage of more than 100,000 kilometers, ranking first in the world. As we all know, the train will cause nonlinear vibration of the wheel rail and sleeper rail during the running process. These vibrations contain a large amount of mechanical energy. Through the energy recovery and collection device, we can convert it into usable electrical energy. These collected The generated energy can be used for auxiliary equipment at level crossings of roads and railways, emergency power supply, and small lighting power supply such as small platforms in o...

Problems solved by technology

[0006] The device involved in the above scheme uses the laid piezoelectric element to collect vibration energy, which has the following defects: firstly, the piezoelectric element has low power generation efficiency, and the power is at the microwatt level, which has little effect on practical application; secondly, the device needs to be Before laying the wheel and rail, it is installed under the sleepers, which requires a large space and is likely to cause hidden dangers to railway safety; moreover, the piezoelectric element laid under the wheel and rail sleepers has a shorter service life than the mechanical structure, and is more susceptible to external physical factors. High maintenance and maintenance costs

[0008] The above scheme is to use the vibration brought by the train passing through the device to generate electricity, which has the following defects: first, the vibration is transmitted through the tractor and the blades, which cannot effectively integrate and convert the up and down flying line vibration brought by the train into a single unit. The rotational torque in the direction is output to the generator, resulting in low efficiency; at the same time, the blade structure is fragile, and the device as a whole is easily damaged, resulting in poor stability of the above structure
