AI Technical Summary
The existing hydraulic anti-fall elevator ventilating fans stop operating in the event of power outage, resulting in lower air circulation in the elevator and an increase in temperature and oxygen content, which may lead to critical situations such as heat stroke.
An anti-fall elevator is designed. By setting a bottom ventilation window and an upper ventilation window in the elevator, an air duct that penetrates the upper ventilation window is formed. Under the control of the control device, the upper ventilation window is driven upwards through the transmission device to expose a cavity, and cooperate with the bottom ventilation window to form an air duct, realizing the air replacement inside the elevator.
In the event of a power outage of the elevator, the internal air circulation is accelerated through the formed air duct to avoid too low oxygen content and too high temperature, ensure passenger safety, and provide escape outlets in extreme situations.

[0002] Hydraulic anti-fall elevator is an elevator that uses hydraulic system as driving force. It has the advantages of simple structure, easy maintenance and stable operation. However, due to the working principle of hydraulic system, its speed is slow, so hydraulic anti-fall elevator is generally suitable for low-rise buildings or places with small load. Due to its good anti-fall performance and small installation space, it is the main choice for installing elevators in low-rise buildings such as villas.
[0003] In the prior art, since the anti-fall and anti-pinch functions of the elevator are relatively complete, when the elevator breaks down, passengers need to wait for rescue in the elevator. When there is a power outage, the ventilation fan of the elevator will mostly stop, and even the backup power supply will stop within a certain period of time. In actual use, without the auxiliary ventilation of the fan, the air circulation in the elevator will be reduced, especially in summer, the temperature and oxygen content in the elevator will rise, which can easily lead to critical situations such as heat stroke.
[0004] A fall-proof elevator is proposed for this reason. Utility Model Content
