An accident scene protection warning retractor

Abstract

The invention relates to the field of safety warning technology, and provides a simple structure and convenient operation accident scene protection warning retractor, which can greatly reduce the operation time for establishing warning signs, improve the efficiency of warning sign establishment, and quickly meet the warning function of the accident scene, and A separate large-area fully sealed micro-prism reflective cloth structure not only has the advantages of concentrated reflective area, large reflective area, and wide range of reflective viewing angles, but also has the advantages of convenient retraction and operation of fully sealed micro-prism reflective cloth, small footprint, and retractable Mounting on the roof of a police vehicle facilitates efficient and quick deployment.

Description

technical field [0001] The invention relates to the technical field of safety warning devices, in particular to an accident scene protection warning retractor. Background technique [0002] With the development of transportation, the frequency of traffic accidents also increases, which is the most important cause of road congestion and traffic paralysis. Therefore, traffic safety has become the primary issue for people to travel and drive. For traffic accidents that have occurred, emergency treatment must be done quickly at the accident site, and the most important principle at the accident site is to evaluate the safety of the accident site as soon as possible to ensure the safety of the surrounding environment of the accident site and prevent secondary accidents. Accidents happen. [0003] Therefore, in order to protect the accident scene and prevent secondary accidents, in order to play a safety warning role, the accident scene investigation vehicle should be equipped wi...

Problems solved by technology

[0003] Therefore, in order to protect the accident scene and prevent secondary accidents, in order to play a safety warning role, the accident scene investigation vehicle should be equipped with a vehicle-mounted luminous warning screen, a luminous (reflective) road cone, a luminous (reflective) warning sign, etc. On-site safety protection facilities. Among them, the luminous warning facilities need to provide additional power to be able to emit light normally. At the accident site, these luminous safety protection facilities cannot guarantee effective normal work due to the power, which greatly limits the application site and application time limit of the luminous warning facilities. It is not conducive to safety warning; and the existing accident reflective warning signs, warning screens, reflective road cones and other warning devices that do not need power supply light, are not limited by power supply, and the application site is not limited, but these reflective warning devices are bulky and heavy. It takes up a lot of space on the car, which is not conducive to handling, and it cannot be put into use quickly in the first limited time, especially in the accident scene of high-speed dangerous roads. Only the warning lights cannot guarantee the operation of the police in the road section 200 meters behind the dangerous accident scene. For their own safety, the police need to set up accident warning signs 200 meters behind the accident. Multiple road cones are moved and placed, which is labor-intensive and takes more than 10 minutes to send. A few road cones are placed at the accident site , is too scattered, the area is not concentrated, and the reflective area is small. The reflective area of ​​a road cone is only 0.01 square meters of visible area, which cannot effectively ensure traffic safety, especially in bad weather conditions, and cannot efficiently maintain the accident scene

[0004] The existing reflective warning screens and protective road cones still have the disadvantage of a single reflective material. They only rely on the retroreflective properties of the reflective material and the eye-catching function of the warning signs to play a role. There is no sufficient light source at night or in low visibility, and there is no fog in cloudy, rainy days. At the scene of an accident in harsh weather conditions such as snow and haze, the penetration performance of retroreflective light is weakened, and the reflected brightness cannot be achieved, and the viewing distance is greatly shortened.

At the accident scene on dangerous highways, urban roads and other highways with heavy traffic and fast speeds, the warning signs cannot be detected and recognized by the driver as soon as possible, and it cannot provide more adequate protection for drivers who are short-sighted, presbyopic or fatigued. Response time reduces the safety factor of accident site protection to a certain extent
