Power generation type elevator

Abstract

The invention provides a power generation type elevator. The power generation type elevator comprises a motor, frequency converter, a wind wheel device and an electric control device, wherein the motor is connected with an electric network through the frequency converter; the wind wheel device is arranged above the top of a building and is connected with the motor through a first controllable driving device; the motor is also connected with a towing wheel in the elevator through a second controllable driving device; and the electric control device is connected with the first controllable driving device, the second controllable driving device and the frequency converter respectively. By adoption of the structure, the power generation type elevator is good in energy-saving effect, simple in structure and low in investment cost, and can effectively use the wind energy on top of the building.

Description

Technical field: [0001] The invention relates to the field of elevator technology and utilization of renewable energy, in particular to an energy-creating elevator utilizing renewable energy. Background technique: [0002] With the increasing application of elevators in modern buildings, more and more attention has been paid to the energy saving of elevators. The application and promotion of energy-generating elevators have huge economic and social benefits. The existing elevator energy-saving technologies generally have the following types: 1. The energy-saving of elevator traction machine drive technology is reflected in the drive from AC asynchronous motor to permanent magnet synchronous motor, and from transmission with gear reducer to drive without gear reducer; 2. The energy saving of elevator drive control technology is reflected in the change of pole speed regulation of AC asynchronous motor to AC voltage regulation (ACVV), and then to AC variable voltage and frequen...

Problems solved by technology

However, although the power saving effect of this elevator with energy feedback device is significant, it is not easy to quantify, and the power saving efficiency is not uniform.

On the other hand, high-rise buildings themselves have abundant energy sources, such as wind energy or solar energy on the roof, which will be a huge waste if not utilized.

[0004] Therefore, there are also people who propose to utilize solar energy or wind energy to supply power to the elevator at present, such as the utility model patent of CN201458457U with the publication number, but this technical scheme only uses the solar power station or the wind power station as the power supply of the elevator, and has nothing to do with the elevator itself. relationship, and the system is huge and complex, especially with the huge investment cost of solar power or wind power, so it is difficult to implement due to lack of rationality
