Problems solved by technology

[0006] The power generation device designed by the above technical solution vibrates the piezoelectric device to generate amplitude, and the free charges move directionally to form a current. However, in use, due to the material of the piezoelectric plate, when subjected to large vibrations, It is easy to collide and cause damage to the piezoelectric plate, affecting its normal use and reducing its normal service life

Abstract

The invention discloses a self-powered method of a train platform based on multiple piezoelectric crystals. The method comprises the following steps that S1, when a platform freight trolley transportsgoods on a pressing plate with a power supply mechanism laid on a platform body, the pressing plate generates bearing force perpendicular to the ground and parallel to the ground due to pressure andfriction force; S2, the generated bearing force perpendicular to the ground and the generated bearing force parallel to the ground are transmitted to a power supply mechanism; S3, the piezoelectric plate is driven to vibrate repeatedly through an arranged elastic mechanism, so that the guide rod stretches out and draws back periodically in the sleeve; S4, the spring and the guide rod drive the piezoelectric plate to move, so that the piezoelectric plate moves back and forth, mobile charges are formed in piezoelectric ceramics on the piezoelectric plate, and current is generated; S5, the charges are conveyed to the first rectifier through a wire connected with the piezoelectric plate, the negative charges are conveyed to the second rectifier, and the charges are collected through the collector; and piezoelectric materials are reasonably utilized on the platform, electric energy generated by the piezoelectric materials is collected and utilized, and energy is effectively saved.

Description

technical field [0001] The invention belongs to the field of power supply for train platforms, in particular to a self-power supply method for train platforms based on multi-piezoelectric crystals. Background technique [0002] The most widely used rail transport in the world is rail freight; under appropriate circumstances, rail freight is much cheaper than road freight, and it also saves energy; rail freight is most suitable for long-distance transportation of large quantities of goods; the biggest advantage of rail freight is the freight rate Cheap and safe; the way of train freight is usually to use transport cars to transport the goods to the compartments, especially at night, the platform needs to provide a lighting system. The platform lighting system needs to provide a large amount of electric energy, which causes a waste of resources to a certain extent. [0003] For the application and development of new energy, car lanes are laid on the platform, and the pressure ...
