Description

Technical Field

[0001] The invention belongs to the technical field of elevator safety, and in particular relates to an elevator emergency fire extinguishing device. Background Art

[0002] With the continuous development of the field of elevator fire extinguishing devices, existing elevator fire extinguishing device products have been widely used. However, these products still have some problems in actual use. For example, existing elevator fire extinguishing devices usually have problems such as slow response speed, low degree of automation, unstable fire extinguishing effect, etc., which leads to the inability to extinguish the fire quickly and effectively when a fire occurs, thereby increasing the risk of casualties and property losses.

[0003] In order to solve these problems, there have been some attempts, such as increasing the response speed and fire extinguishing effect of fire extinguishing devices by adding sensors and automated control systems.

[0004] Specifically, after searching, an intelligent fire prevention method and system for elevators with a publication number of CN104016202B was disclosed, and the publication date was 2017-02-01. The design uses sensors to monitor the temperature parameters, smoke parameters, side displacement parameters and acceleration parameters of the elevator in real time, and sends out warning signals and fire extinguishing signals when the temperature and smoke parameters are higher than the standard parameters. Although the design can achieve fire warning and fire extinguishing to a certain extent, since it relies on the collaborative work of multiple sensors, the system complexity is relatively high, and it is prone to misjudgment or response lag when the sensor fails or the signal transmission is delayed, resulting in unstable fire extinguishing effect. In addition, the design mainly focuses on fire warning and initial fire extinguishing, and has weak support capabilities for continuous fire extinguishing and personnel escape after the fire occurs.

[0005] After searching, a self-rescue device for a fire rescue elevator was disclosed with a publication number of CN106276471B and a publication date of 2018-11-09. This product uses an electric push rod and a cutting device, which can quickly realize the escape of people in the elevator car when the elevator car fails and falls or is stuck in the elevator shaft. Although this design can provide escape support in an emergency, its main function is to help people escape, and its fire extinguishing effect and continuous fire extinguishing ability are relatively weak when a fire occurs. In addition, this design relies on the normal operation of the electric push rod and the cutting device. Once the power supply or mechanical components fail, its escape function will be affected.

[0006] The above problems show that the elevator fire extinguishing devices currently on the market are difficult to effectively respond to the new requirements for rapid response, precise fire extinguishing and personnel escape support under complex working conditions. Therefore, the present invention provides an elevator emergency fire extinguishing device to overcome these shortcomings and provide a new solution that is more intelligent, efficient and adaptable to changing environments. The device can not only quickly start fire extinguishing at the beginning of a fire, but also maintain a stable fire extinguishing effect during the fire, and provide personnel escape support when necessary, thereby effectively improving the safety and reliability of the elevator in the event of a fire.
