Description

Self-generating railway street lamp using gravitational potential energy and suction force for power generation

The invention belongs to a lighting device, in particular to a street lamp that uses natural energy to generate electricity.

Background technique

In order to save energy and protect the environment, street lamps that use solar energy and wind energy to provide electricity have emerged. These two natural energy street lights are especially suitable for lighting along railways. Because the illumination of long-distance railway lines consumes considerable power resources. However, both sources of energy are unstable. For example, on a continuous rainy day, the power supply of solar street lights becomes a problem. Windless street lights will stop working in continuous windless or breezy weather. Studying a streetlight along a railway powered by stable natural energy has become an important issue.

Another disadvantage of existing solar and wind energy street lamps is the need to configure a chemical battery, which is regularly maintained and has a limited service life. The waste battery also pollutes the environment, and this state needs to be improved.

Another noteworthy phenomenon is that: On both sides of the high-speed railway, guardrails are usually built to prevent passers-by from blindly approaching the track and being injured by the high-speed train that is instantaneous. Because of the high-speed airflow generated by the rapid transit of high-speed trains, there is a suction effect on people or objects on both sides of the railway. If people or objects are too close to the high-speed train, they will be sucked into the train by this suction force. This phenomenon can be explained by Bernoulli's principle. The faster the flow rate, the lower the pressure, so people or objects close to the train will be pushed from the high pressure zone to the low pressure zone.

Summary of the invention
