A platform screen door and system for ensuring safety

Abstract

The present invention discloses a safety-enhancing shielding door and its system, comprising a door frame and a fixed door body fixed within the door frame. A movable door body is further provided within the door frame. A guide rail is fixed to the inner wall of the door frame. A groove is formed at the bottom of the movable door body. A plurality of rollers are provided on the inner wall of the groove, which rotates via a rotating shaft. The present invention relates to the technical field of shielding doors. The safety-enhancing shielding door and its system, when operated rapidly by a dual-axis motor, drives a turntable to rotate rapidly, which in turn drives a piston to rapidly reciprocate within an air suction cylinder via a transmission rod and a triangular block. When the piston moves to the left, impurities within the guide rail enter a conduit through a double-ended suction pipe, and then enter a filter cylinder through an air intake valve, where they are filtered and blocked. This allows for rapid removal of impurities, prevents accumulation of impurities within the guide rail, reduces the workload of staff, avoids manual cleaning by staff, and improves cleaning efficiency.

[0011] Beneficial effects

[0012] The present invention provides a screen door and its system that ensures safety. Compared with the prior art, it has the following advantages:

[0013] (1) The shield door and its system for ensuring safety, when the dual-axis motor runs fast, will drive the turntable to rotate quickly, and then drive the piston to move back and forth quickly inside the suction cylinder through the transmission rod and the triangular block. When the piston moves to the left, the impurities inside the guide rail will enter the conduit through the double-headed suction pipe, and enter the filter cylinder through the air intake valve and be filtered and blocked, so that the impurities can be quickly removed and the impurities will not accumulate inside the guide rail, which reduces the workload of the staff, avoids manual cleaning by the staff, and has high cleaning efficiency.

[0014] (2) The shielding door and its system for ensuring safety have two magnetic plates with opposite magnetic poles on the sides close to each other. The attraction between the opposite magnetic poles is used to make the inner sealing strip fit tightly with the outer sealing strip, thereby strengthening the sealing between the movable door body and the door frame.

[0036] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0037] During operation, the face recognition device 10 transmits a signal to the controller 11, which is then driven by the controller 11 to drive the dual-axis motor 13, thereby driving one of the rollers 7 to rotate, and then driving the entire movable door body 3 to move, thereby realizing the opening of the movable door body 3.

When the piston 84 moves to the left, the impurities inside the guide rail 4 will enter the conduit 89 through the double-headed suction pipe 810, and enter the filter cylinder 88 through the air inlet valve 811 and be filtered and blocked. When the piston 84 moves to the right, the air inside the suction cylinder 83 is discharged through the air outlet pipe 812 and the air outlet valve 813, and then the above work is repeated, so that the impurities inside the guide rail 4 can be automatically cleaned. When too much impurities accumulate inside the filter cylinder 88, the sealing door 15 can be opened through the inspection port 14 to pour out the impurities inside the filter cylinder 88.
