Ventilated safety elevator for smart city

Abstract

The invention discloses a ventilated safety elevator for smart cities, comprising a car, an active fan, an active air intake pipe, a dynamic air intake pipe, a purification channel, an air purification device, an air outlet channel, an exhaust port, an anion generator, carbon dioxide The measuring instrument, the installation window, the U-shaped support frame, the lower beam, the permanent magnet, the first through hole, the second through hole, and the upper surface of the U-shaped support frame are uniformly provided with a plurality of shock absorbing mechanisms, and the top of the shock absorbing mechanism is provided with The movable car bottom is provided with a door-shaped connecting bracket between the second through holes. The invention is simple and reasonable in structure, quick and convenient to use, improves the comfort of passengers, improves the quality of the air entering the car, and increases the safety of the elevator ride; the cushioning airbag avoids the contact and friction between the car and the well wall, When driving, the airbag can play a certain buffering role, and the safety factor is greatly improved.

Description

technical field [0001] The invention relates to an elevator, in particular to a ventilated safety elevator used in smart cities. Background technique [0002] The elevator is powered by a motor and equipped with a box-like gondola for multi-storey buildings to take people or carry goods. The vertical elevator has a car that runs between at least two vertical rigid guide rails. Hydraulic elevators began to appear in the mid-19th century and are still used in low-rise buildings today. In 1852, E.G. Otis of the United States developed a safety elevator for wire rope lifting. In the 1980s, the driving device was further improved, such as the motor driving the winding reel through the worm drive, and the use of a balance weight. At the end of the 19th century, friction wheel transmission was adopted, which greatly increased the lifting height of the elevator. At the end of the 20th century, elevators were driven by permanent magnet synchronous traction machines, which greatly ...

AI Technical Summary

Problems solved by technology

If the passenger stays in the closed elevator for a long time, the air in the elevator will not be replenished, making the passengers very uncomfortable. The elevator in the prior art solves the problem of air circulation by being communicated with the elevator shaft, but the air in the elevator shaft The air quality cannot be guaranteed, and while the elevator provides convenience to people, it is also accompanied by danger. If the elevator is overloaded, the elevator will either be in danger of stagnation or fall, which will bring harm to people's life safety. Will bring damage to the elevator equipment

In order to prevent the phenomenon of elevator overloading, instruments to prevent elevator overloading have also been developed. However, these instruments have certain defects in structural design, poor measurement accuracy and poor measurement reliability, and cannot meet the high precision and high standards of elevator operation.
