Safety early warning device for loading and unloading of hazardous chemical substance vehicle

Abstract

The safety early warning device comprises a vehicle-mounted base and a material tank, the material tank is fixedly installed at the upper end of the vehicle-mounted base, a bottom plate is fixedly installed at the tail of the material tank, and a first conveying opening is fixedly formed in one side of the lower end of the bottom plate; the first conveying opening and the second conveying opening are formed in the lower portion of the front face of the bottom plate of the material tank, the second conveying opening is connected with one side of the first conveying opening through the guide pipe, and the electromagnetic control valve is installed on the guide pipe, so that when pipeline breakage occurs during conveying of the first conveying opening, the electromagnetic control valve is installed on the guide pipe; a second conveying opening can be used for recycling, a pressure detector is installed on a first conveying opening and used for monitoring whether a conveying pipeline of the first conveying opening leaks or not, and then data information can be transmitted to a warning lamp, an electromagnetic control valve and a hydraulic cylinder in time; and then the first conveying opening is sealed in time.

Description

technical field [0001] The present invention relates to the field of safety warning devices, in particular, to a safety warning device used for loading and unloading hazardous chemicals vehicles. Background technique [0002] Hazardous chemicals, also known as hazardous chemicals, refer to highly toxic chemicals and other chemicals that are toxic, corrosive, explosive, combustible, and combustion-supporting, and are harmful to humans, facilities, and the environment. In the road transportation of hazardous chemicals, hazardous chemicals vehicles are usually used for transportation. Hazardous chemicals vehicles enter a specific loading and unloading location in the hazardous chemicals vehicle passage (suitable for rectangular fixed loading and unloading parking spaces for hazardous chemicals vehicles), and transfer the hazardous chemicals from the hazardous chemicals storage tank and load them onto the hazardous chemicals vehicles It is a very dangerous operation to load and...

AI Technical Summary

Problems solved by technology

In the process of loading and unloading, it often happens that the installation of the crane pipe is not in place, resulting in the leakage of hazardous chemicals

Moreover, dangerous chemicals loading and unloading trucks often cause crane tubes to be strained or even broken due to misstarting, resulting in leakage of hazardous chemicals. In serious cases, vicious accidents such as fire, explosion, poisoning, etc. occur, and the safety is poor.
