Abstract

The invention discloses a cofferdam used for preventing drain diffusion of dangerous chemicals unloaded from a vehicle. The cofferdam comprises a cofferdam main body and a liquid waste disposal tank; the cofferdam main body is formed by encircling of three upright cofferdams and one bevel cofferdam; a vehicle storage plane is arranged on the cofferdam main body; an inclined angle alpha between the vehicle storage plane and the bottom surface of the bevel cofferdam is 3-15 degree; a groove is formed in one side, close to the bevel cofferdam, of the vehicle storage plane; a liquid level sensor is arranged at the bottom of the groove; the liquid level sensor is connected with an automatic induction alarm device by an electric signal; the groove is connected with the liquid waste disposal tank by a groove conduit; the cofferdam main body is connected with the liquid waste disposal tank by a cofferdam conduit; the cofferdam conduit is arranged in the vertical cofferdam and is close to one end of the bevel cofferdam; a grid pad is paved on the vehicle storage plane; and when dangerous chemical liquid leaks or overflows to the ground, a person can stand on the cofferdam so as to be convenient for emergency disposal. The cofferdam has the advantages of being simple in structure and strong in practicability.

Description

technical field [0001] The invention relates to a cofferdam used for vehicles to load and unload hazardous chemicals to prevent leakage and diffusion. Background technique [0002] In industrial plants producing liquid hazardous chemicals, warehouses, oil tanks, storage bins and underground devices for storing hazardous chemicals, the hazardous chemical vehicles transporting liquids are basically large tank diesel locomotives. [0003] When the tank truck is loading or unloading liquid dangerous chemicals, due to improper operation, valve problems, pipeline problems or other unexpected reasons, the phenomenon of sudden escape and leakage of dangerous chemical liquid often occurs, causing accidents occur or pollute the environment. [0004] In addition, when the liquid storage tank in the chemical plant leaks, the contaminated area will continue to spread, which will bring great inconvenience to the post-processing. Contents of the invention [0005] In order to overcome ...
