A self-generating railway street light that generates electricity using tension springs and suction

Abstract

The invention relates to a self-generating railway street lamp which utilizes tension spring and suction force to generate power. When passing through, the oscillating device swings with the suction force, and the oscillating force makes the elastic potential energy generating device of the tension spring accumulate elastic potential energy, and the elastic potential energy generating device of the tension spring is regulated by the mechanical time setting device at night, releasing the elastic potential energy to drive the generator to generate electricity , for street lighting. The beneficial effect is that the suction power generated when the high-speed train is running is used to generate electricity, and the electric power for railway street lamp lighting is provided, thereby avoiding the disadvantages of unstable electric power of existing wind energy and solar street lamps. It also saves power resources of the public grid. Using tension springs to store the elastic potential energy of power generation instead of batteries to store electricity, avoids the environmental pollution of chemical batteries, and also avoids the shortcomings of short life and frequent maintenance of chemical batteries.

Description

technical field [0001] The invention belongs to lighting equipment, in particular to a street lamp which utilizes natural energy to generate electricity. Background technique [0002] In order to save energy and protect the environment, there have been street lamps that utilize solar energy and wind energy to provide electricity. These two natural energy street lamps are especially suitable for lighting along railway lines. Because the lighting of long-distance railway lines consumes considerable power resources. However, both energy sources are unstable. For example, in continuous rainy days, the power supply of solar street lights becomes a problem. In continuous windless or light windy weather, wind energy street lights will stop working. It has become an important subject to study a street lamp along the railway that utilizes stable natural energy for power supply.

Problems solved by technology

[0003] Another disadvantage of existing solar and wind energy street lights is that chemical batteries need to be configured, and chemical batteries require regular maintenance and have a limited service life. Discarded batteries will also pollute the environment, and this situation needs to be improved.
