A protective device for rail traffic signal lights

Abstract

The invention discloses a protective device for rail traffic signal lights, which belongs to the technical field of rail traffic. In harsh environments, the carbon dioxide aqueous solution in the liquid storage tank is shaken by wind blowing, causing carbon dioxide gas to overflow, and the expansion of the telescopic air bag pushes the The rods move towards each other, so that the connecting frame is supported and fixed by the contact plate and the adsorption pad, and the protective cover and the buffer pad can buffer and protect the signal lamp body to avoid damage to it. High, so that the magnetism of the second magnet is weakened, so the attractive force between it and the first magnet is reduced, and it starts to move away from it under the action of the second spring, and the heat dissipation hole cooperates with the heat dissipation silicon grease in the heat dissipation sleeve to accelerate the heat dissipation. Reduce its ambient temperature, so the second magnet begins to return to its original position, so that the impact ball collides with the arc-shaped retaining frame, and the vibration generated by the collision shakes off the dust and water drops on the light body of the signal lamp, and falls into the collection box.

Description

technical field [0001] The invention relates to the technical field of rail traffic, more specifically, to a protective device for rail traffic signal lights. Background technique [0002] Rail transit refers to a type of vehicle or transportation system that operating vehicles need to run on a specific track. It has the characteristics of large capacity, fast speed, safety, punctuality, environmental protection, energy saving and land use. In rail transit, rail traffic signal lights are an important part of rail traffic. A reasonable design of rail road intersection signal lights can improve the traffic capacity of the intersection, reduce traffic conflicts, and reduce the frequency of traffic accidents; on the contrary, if the design is unreasonable, then It will increase the delay of vehicles at the intersection, reduce the traffic capacity, and cause an increase in the number of traffic accidents. [0003] The rail traffic signal lights of the prior art have poor protec...

In rail transit, rail traffic signal lights are an important part of rail traffic. A reasonable design of rail road intersection signal lights can improve the traffic capacity of the intersection, reduce traffic conflicts, and reduce the frequency of traffic accidents; on the contrary, if the design is unreasonable, then It will increase the delay of vehicles at the intersection, reduce the traffic capacity, and cause an increase in the number of traffic accidents

[0003] The rail traffic signal lights of the prior art have poor protection, and are prone to topple over and cause damage under the influence of wind in harsh environments. At the same time, factors such as rain, snow and dust will also cause damage to them, affecting their work, greatly reducing their service life and work rate, for which we propose a protective device for rail traffic signal lights
