Warning device used in subway platform

Abstract

The invention belongs to the field of subway safety facilities, particularly relates to a warning device used in a subway platform. The warning device is characterized in that the warning device comprises a plurality of L-shaped ventilation slots formed equidistantly in the platform, and openings of horizontal portions of the L-shaped ventilation slots are formed towards a track. Horizontal rotating shafts are rotatably connected to the inner walls of the L-shaped ventilation slots. The ends, away from the L-shaped ventilation slots, of the rotating shafts extend to the outside of the platformand are fixedly connected with wind wheels, arc-shaped grooves corresponding to the wind wheels are formed in the installation surface of the track, the upper end portions of the wind wheels are exposed outside the arc-shaped grooves, and axial flow fans are coaxially connected to the rotating shafts located in the L-shaped ventilation slots. Annular limiting blocks are fixedly connected to the inner walls of the L-shaped ventilation slots, and floating plates are arranged on the upper sides of the annular limiting blocks. The warning device has the advantages that strong wind accompanied bysubway arrival is utilized, indirect warning to passengers is carried out, and the electromagnetic induction technology is used for improving the warning effect.

Description

technical field [0001] The invention belongs to the technical field of subway safety facilities, in particular to a warning device used in a subway platform. Background technique [0002] Subway is a form of railway transportation, which refers to the urban rail transit system that mainly runs underground, that is, the abbreviation of "underground railway" or "subway". Compared with other means of transportation in the city, in addition to avoiding urban ground congestion and making full use of space, the subway has many advantages: large transportation capacity. The transportation capacity of the subway is 7 to 10 times larger than that of the ground bus, which is unmatched by any urban transportation; on time, the punctuality rate is generally higher than that of the bus; the speed is fast, the subway train travels in the underground tunnel, and the highest driving speed The speed is generally 80 kilometers per hour, but it can exceed 100 kilometers and some even reach 12...

AI Technical Summary

Problems solved by technology

[0003] When the subway enters the station, due to the high speed of the subway, the air velocity around the subway will be large, the pressure between the person and the subway will be small, and the person will be pressed to the subway under the pressure difference, causing danger. There are many warning lines marked, and staff and volunteers are equipped to warn passengers to prevent passengers from crossing the yellow line and reduce the probability of danger. In the absence, there will still be cases of crossing the line

In addition, due to the high speed of the subway, there will be strong winds when entering the station, and a large amount of wind energy has not been fully utilized
