Rail transit safety platform with Lenz law as principle

Abstract

The invention discloses a rail transit safety platform with a Lenz law as a principle. The rail transit safety platform comprises a platform body, wherein a mosaic shell is fixedly arranged at the right side of the platform body; a balance plate is movably arranged on the lower end in the mosaic shell; the balance plate is in a balance state normally; a sliding block is arranged on the upper surface of the left end of the balance plate in a sliding mode; the upper end of the sliding block is elastically connected to a fixing shell through a pressure spring; a fixing rod is fixedly arranged onthe upper surface of the fixing shell; and a pedal is fixedly arranged at the upper end of the fixing rod. Through the cooperation of the balance plate, the sliding block, the fixing shell, the pressure spring, the fixing rod, the pedal and an extrusion spring, the lifting of a safety baffle can be conveniently driven when people pass a yellow line, the pedestrian can be isolated from places except the safety area and the pedestrian can be prevented from continuously advancing, so that the safety and health effects of the people are guaranteed, the accidents are avoided, and the station disorder is avoided.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a rail transit safety platform based on Lenz's law. Background technique [0002] The safety of rail transit has always been a matter of concern and attention to people. In the process of daily travel, people often take high-speed trains and other convenient and fast means of transportation. Among them, when the train enters the station, in order to ensure the safety of pedestrians, a There is a yellow line at the waiting platform in the moving city to remind people to retreat to the safe area. [0003] However, judging from daily travel observations and news reports this year, these yellow lines do not serve as a warning. When standing, the speed of air flow between the person and the car will be accelerated. At this time, the air flow speed outside the person is slow. According to the relationship between fluid pressure and flow velocity, it can be known that the air flow...

Problems solved by technology

[0003] However, judging from daily travel observations and news reports this year, these yellow lines do not serve as a warning. When standing, the speed of air flow between the person and the car will be accelerated. At this time, the air flow speed outside the person is slow. According to the relationship between fluid pressure and flow velocity, it can be known that the air flow speed outside the person is slow and the pressure is strong, while the flow speed inside the person is fast and the pressure is small. There will be a pressure difference inward, pushing people to the train, which is prone to danger and cannot guarantee the safety of pedestrians. Moreover, once an accident occurs, the original departure order in the station will be disordered, affecting the arrival of the following trains
