AI Technical Summary

Technical Problem

Traditional elevator waterproof warning devices suffer from sensor sensitivity degradation or abnormal status after prolonged periods of inactivity, leading to missed or false alarms. This increases maintenance costs and safety risks, and sensor status changes are difficult to detect quickly, affecting the normal use of the elevator.

Method used

By combining mechanical structure with buoyancy principle, the system uses components such as water inlet, sealing membrane, float and tactile switch to use buoyancy to push float to trigger alarm and drainage, avoiding dependence on sensors and realizing automatic monitoring, early warning and drainage integration.

Benefits of technology

It effectively avoids missed or false alarms caused by sensor failure, reduces maintenance costs, improves elevator operation safety and efficiency, and ensures the accuracy of early warning and the timeliness of drainage.
