AI Technical Summary
Existing subway platform safety doors are prone to scratching the tempered glass surface during cleaning, increasing the workload of manual cleaning and shortening their service life.
A safety gate comprising a cleaning component and a limiting component was designed. The cleaning component slides on the glass surface via a hydraulic push rod and a cleaning brush, and sprays cleaning fluid using a delivery pump and a seepage plate to avoid direct contact and scratches. The limiting component enables easy installation and removal of the protective plate via a plug rod and a limiting ring, simplifying maintenance procedures.
This technology avoids scratching the tempered glass surface during cleaning, reduces manual cleaning workload, and improves the convenience and maintenance efficiency of security doors.
