Description

Technical Field

[0001] The present invention relates to the technical field of subway operation equipment, and in particular to a three-dimensional greening lighting device in a subway station based on power generation by pedestrian stepping pressure. Background Art

[0002] Pressure power generation is a technology that converts pressure energy generated by activities such as walking and running into electrical energy. As an emerging pressure power generation technology, stepping-type pressure power generation has gradually attracted attention. Stepping-type pressure power generation utilizes the characteristics of piezoelectric materials and converts mechanical pressure into electrical energy through the piezoelectric effect. The stepping-type pressure power generation system usually consists of a piezoelectric sheet, a mechanical structure, and an electronic device. When stepping on the piezoelectric sheet, mechanical pressure is generated, which causes the piezoelectric sheet to deform and generate electric charges. These charges are collected, stored, and used to eventually output electrical energy.

[0003] In order to beautify the subway station environment and improve the comfort of passengers, it is possible to consider planting green plants in the subway station. However, subway stations are located in underground spaces, and greening must require supplementary lighting measures to ensure the growth and metabolism of green plants. Long-term operation of supplementary lighting measures will inevitably lead to increased energy consumption. Since there are a large number of passengers walking in the subway station, the pedaling pressure power generation system can be used as an energy source for supplementary lighting measures for green plants in the subway station. The existing practical applications of pedaling power generation mostly focus on the combined use of pedaling power generation devices with fitness equipment, street lights and other items, and there are few mature products that can be applied to supplementary lighting for green plants in subway stations.

[0004] Therefore, it is necessary to propose new measures to apply the step-on pressure power generation technology to subway stations to beautify the environment while reducing energy consumption. Summary of the invention

[0005] The purpose of the present invention is to provide a three-dimensional greening lighting device in a subway station based on pedestrian stepping pressure power generation, so as to solve the current problem of lack of energy for green plant lighting in subway stations based on stepping pressure power generation.

[0036] like Figure 1-4 , the device includes a power generation module and a planting module.

[0037] The power generation module includes a rubber shell composed of a rubber plate 1, which is in the shape of a square plate. Multiple power generation modules are closely laid in an array on the ground in the subway station. Rubber materials are conducive to force conduction and can effectively protect the equipment wrapped inside. The rubber shell includes a rubber bottom plate and a rubber top plate. A sunken groove is provided in the middle of the rubber bottom plate. The piezoelectric material 3, a rectifier 5, a filter 6 and a voltage stabilizer 7 are provided in the groove.

[0038] In addition, in some embodiments, a waterproof rubber strip 8 is provided at the top of the gap between adjacent power generation modules, and the cross section of the waterproof rubber strip 8 is T-shaped, which fixes the rubber top plate and prevents water from leaking in. In other embodiments, the rubber shell can also be designed into other shapes such as rectangle and hexagon according to actual needs.

[0039] The piezoelectric material 3 includes but is not limited to single crystal materials, piezoelectric polymers, piezoelectric ceramics, piezoelectric composite glass ceramics, etc. The piezoelectric material 3 is deformed by pressure, generating a voltage difference, thereby converting kinetic energy into electrical energy, and the generated electrical energy is output through the wire 4.

The battery 9 is installed inside the wall next to the power generation module.

[0046] After the power generation module is installed, when pedestrians walk through this area, they exert force on the rubber plate, and transmit the force to the air bag 2 through the rubber plate, and then transmit it to the piezoelectric material 3, causing the piezoelectric material 3 to generate deformation and generate electricity. The lead-out wire 4 is connected to the rectifier 5, filter 6, voltage stabilizer 7, etc., and relatively stable electric energy is exported and stored in the battery 9.
