Escalator capable of autonomously generating electricity

Abstract

The invention discloses an escalator capable of autonomously generating electricity. The escalator comprises a step unit, a driving unit for driving the step unit to operate, and at least one conductor; the step unit comprises multiple steps, a step transmission chain for connecting the multiple steps as a loop, and a guide rail set for guiding and supporting operation of the steps; magnetic components for generating magnetic fields are arranged on the back surfaces of pedals of at least one step; the driving unit drives the step transmission chain to drive the multiple steps to operate alongthe guide rail set; the at least one conductor is arranged in an area surrounded by the steps; and when the steps are operated, the at least one conductor cuts magnetic induction lines generated by magnetic components to generate electric energy. In the escalator capable of autonomously generating the electricity, the electric energy can be generated in the operating process of the escalator, so that the escalator achieves the effect of autonomous power generation when meeting a traditional passenger conveying function, higher economy and energy conservation are achieved, and the power generation effect is not limited by the escalator operating direction or the passenger taking.

Description

technical field [0001] The invention belongs to the field of energy recovery of escalators, and mainly relates to an escalator capable of generating electricity by itself. Background technique [0002] In daily life, more and more merchants and builders build escalators to take on the task of passenger flow transmission. With the increase in usage, escalator products consume more and more urban electric energy. How to save energy or recycle the energy generated by escalator operation These issues have also gradually attracted the attention of urban planners. Since the escalator is in the fourth phenomenon operating state when carrying passengers down, it is in the power generation state. The existing technology uses energy feedback devices, common DC bus technology or four-quadrant inverter technology to collect the energy generated when the escalator is descending under heavy load. Then feed back to the grid. [0003] However, the existing technology can only use the elec...

AI Technical Summary

Problems solved by technology

[0003] However, the existing technology can only use the electric energy generated by the reduction of the gravitational potential energy of passengers when the escalator is descending with a heavy load, and the escalator is not in the heavy-load downward working condition for a long time, and may be in the upward state or light-load downward state. At this time, the existing technology Escalators cannot be used to generate energy, and the power generation effect of existing technologies is limited to the operating conditions of escalators and the loading of passengers
