The upper end surface of the regulation component is meshed with the shielding component, and the first counterweight grooves are symmetrically arranged on the front end surface of the regulation component. A warning loudspeaker is fixedly installed at the center of the front end surface of the first counterweight groove. By setting the regulation component, when the device is running, if no passengers enter within the specified time, at this time, the pressure sensor can sense the activities of the passengers above the limit baffle through the elastic contraction of the limit baffle and the spring support shaft, and then continue to close the screen door body.

[0035] Working principle and usage process of the present utility model: When in use, in the figure, the friction plate 125 and the locking wheel 126 lock the rotating shaft 10, the gear 11, the tooth groove 6 and the shield door body 5. When a passenger steps on the intelligent stepping induction device 3, the intelligent stepping induction device 3 starts the warning loudspeaker 4 through an external control terminal to give a warning to the passenger. When it is necessary to open the shield door body 5, the motor 122 is started. The motor 122 drives the screw rod 123 to rotate, and the screw rod 123 drives the inclined plate 124 to move downward. The inclined plate 124 withdraws from between the friction plate 125 and the sliding frame 2, creating a certain moving space between the friction plate 125 and the sliding frame 2. The locking force between the friction plate 125 and the locking wheel 126 is lost. The servo motor 9 is started, and the servo motor 9 drives the rotating shaft 10 and the gear 11 to rotate. The gear 11 drives the tooth groove 6 and the shield door body 5 to slide downward, thus having the advantage of high safety and stability.

[0036] In summary: Through the combined use of the low frame 1, the sliding frame 2, the intelligent stepping induction device 3, the warning loudspeaker 4, the shield door body 5, the tooth groove 6, the penetration groove 7, the mounting plate 8, the servo motor 9, the rotating shaft 10, the gear 11 and the locking mechanism 12, this intelligent shield door for high-speed railway stations solves the problem that the servo motor supports and positions the shield door body by positioning and controlling the transmission guide shaft and the connecting gear. Since the shield door body has a moving weight, if the servo motor bears the weight of the shield door body for a long time, it will be crushed by the weight of the shield door body, resulting in the shield door body being unable to be lifted and locked by the servo motor, the shield door body losing its protective effect, and the use stability of the shield door body being reduced.
