Improved new energy elevator

Abstract

The invention discloses an improved new-energy elevator, which comprises a cage, a traction system, a permanent magnet synchronous motor, a first control system for controlling the rotation speed of the permanent magnet synchronous motor in the electric state, a wind energy conversion device for converting wind energy into electric energy, a second control system for controlling the rotation speed of the permanent magnet synchronous motor in the power generation state and an electric power storage device, wherein the permanent magnet synchronous motor, the traction system and the cage are connected by power; the electric energy outputted by the wind energy conversion device and electric energy outputted by the permanent magnet synchronous motor in the power generation state are input into the electric power storage device to be stored; and the electric power storage device is used for providing an operating power supply for the permanent magnet synchronous motor in the electric state. The invention provides the new-energy elevator in which the wind energy is taken as elevator energy.

Description

technical field [0001] The present invention relates to an elevator. Background technique [0002] Traditional elevators generally have the following disadvantages: [0003] 1. The operation of the elevator must rely on the mains power, and the elevator will stop working when the power is cut off. [0004] 2. There is no energy storage device, which wastes the energy released when the load potential energy changes. [0005] 3. When the centrifugal lock brake of the elevator works, the car of the passengers can only hover in the elevator shaft and wait for rescue, and the passengers cannot be sent to the ground to escape. [0006] 4. When a fire breaks out, property management or firefighters cannot use traditional elevators to extinguish the fire and assist trapped people to evacuate. [0007] 5. When a fire occurs, people trapped in the building cannot use traditional elevators to save themselves and escape. Contents of the invention [0008] The main object of the pr...
