[0012] Preferably, an embedding groove is arranged at the position corresponding to the blocking frame on the evacuation platform, a self-locking mechanism is arranged on one side of the embedding groove, the self-locking mechanism comprises an insertion block and a thrust spring, the insertion block is fixedly connected with the thrust spring, the thrust spring is fixed to the side wall of the embedding groove, the insertion block and the blocking frame are arranged as matching inclined surfaces, and a through groove is arranged on the blocking frame.

[0013] The technical effect and advantages of the present application are as follows:

[0014] 1. The present application is suitable for flood-prone areas, and the subway tunnel is easily impacted by flood. Once the personnel are in the subway and cannot be evacuated in an emergency, the personnel will be injured or even killed. Although the existing subway tunnel is equipped with evacuation platforms on both sides, the evacuation platforms cannot be built too wide due to the specifications of the subway tunnel, and can only be used by one or two people at most. Therefore, the personnel are in a state of panic and disorder, which is the biggest challenge to emergency evacuation. The auxiliary evacuation mechanism is arranged for such a situation, which can provide a certain order for evacuation and make the personnel orderly evacuate and escape from the subway tunnel at the maximum speed to avoid casualties.

[0015] 2. To prevent the rapid rise of floodwaters from submerging the evacuation platform and sweeping away personnel walking on it during movement, this invention provides an auxiliary evacuation mechanism. Evacuation personnel only need to hold one end of the safety buckle, wrap it around their waist once, and then fasten it to the safety rope to ensure their safety. Since the slip ring, safety rope, and safety buckle are arranged in an orderly manner, the personnel are passively arranged in a certain order after wrapping themselves around the safety rope, allowing them to move in an orderly manner on the device platform. When the floodwaters rise and impact the evacuation platform, the safety rope will prevent personnel from being easily swept away, ensuring the safety of the evacuation personnel.

[0016] 3. This invention uses an arc angle on one side of the support on each evacuation platform, positioned in the corresponding direction of travel. The slip ring enters the gap between the support and the hanging pole from this arc angle, forcibly compressing the support column and passing it over, allowing the slip ring and the evacuated personnel to move normally. If a flood impacts personnel, it will push the slip ring backward. At this point, the arc angle is only located on the back of the support, while the front is in close contact with the hanging pole. Therefore, the slip ring cannot pass over the support column when it retreats, providing leverage for the personnel to regain stability and adjust their position, preventing them from being swept away. Even if unable to move, they can remain in place and await rescue, thus shortening the rescue distance. Attached Figure Description
