An Efficient Ventilation System for Elevators

Abstract

The invention discloses a high-efficiency ventilation system for elevators and relates to the technical field of elevator ventilation. It includes an elevator body and a ventilation mechanism. A ventilation mechanism is placed on the top of the elevator body. The ventilation mechanism includes a drive plate, a sieve box and a purification mechanism. Two top air inlet pipes and two There are two bottom air inlet pipes, and a three-way valve pipe is fixedly installed between the top air inlet pipe and the bottom air inlet pipe on the same side. This high-efficiency ventilation system for elevators, by setting a sieve box, uses two filter screens to filter the outside air step by step on the way into the elevator, and then cooperates with the first motor to drive the nut seat to slide through the screw rod, so that the two The sliding brush cleans the two filter screens in a continuous and circuitous manner, so that the filter screens are cleaned while purifying the air, thus ensuring the air filtering effect and enabling the elevator personnel to obtain a steady stream of pure air.

Description

technical field [0001] The invention relates to the technical field of elevator ventilation, in particular to a high-efficiency ventilation system for elevators. Background technique [0002] An elevator is a vertical lift powered by an electric motor, equipped with a box-like pod, and used for carrying people or carrying goods in multi-storey buildings. There are also step type, the tread plate is installed on the track to run continuously, commonly known as escalator or moving walk. Fixed lift equipment serving specified floors. Vertical lift elevators have a car running between at least two rows of rigid guide rails that are vertical or inclined at an angle of less than 15°. The size and structure of the car are convenient for passengers to enter and exit or load and unload goods. It is customary to use elevators as a general term for vertical transportation means in buildings regardless of their driving methods. [0003] In the prior art, due to the small space of th...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, due to factors such as the narrow space of the elevator car, the large flow of people, and the lack of air circulation, it will pose a threat to human health and even life. Therefore, there must be a ventilation system in the elevator. The traditional ventilation system is through the elevator. It moves up and down to ensure the air circulation inside the elevator bridge compartment. This is a passive air circulation device. Especially when the elevator is waiting for rescue in an emergency stop failure state, the passive air circulation cannot be carried out, because the inside of the elevator Without ventilation to the outside, long-term sweltering heat and lack of oxygen not only affect people's physical health, but also cause trauma to people's hearts
