Response to small and medium-sized wharf soluble hazardous chemicals loading and unloading leakage liftable fence

Abstract

The invention discloses a liftable fence for dealing with leakage of soluble hazardous chemical substances of small and medium-sized wharfs during loading and unloading. The liftable fence comprises a U-shaped top fixing device, a floating body, a skirt body, a bottom closing device, a plurality of restraint devices and lifting devices, wherein the floating body comprises a plurality of floating cushions which are spaced from one another uniformly; narrow steel plates are uniformly sewn on the skirt body so as to fulfill a foldable function; each restraint device comprises a first fixed pulley, a second fixed pulley, a retaining ring and a steel wire rope; the first fixed pulleys are fixed on two sides of the top fixing device; the second fixed pulleys are fixed on the bottom closing device; the retaining rings are fixed on the top fixing device; one end of each steel wire rope is fixed on the corresponding first fixed pulley; and the other end of each steel wire rope sequentially penetrates through the corresponding second fixed pulley, the corresponding first fixed pulley and the corresponding retaining ring, and then is connected with the corresponding lifting device. When a leakage accident occurs, a winch quickly discharges the ropes, the steel wire ropes move, the skirt body quickly floats up under the effect of the floating body so as to form totally closed space, polluted water is completely isolated in the closed space, and a water pollution range cannot be expanded.

Description

technical field [0001] The invention relates to a liftable fence for dealing with the leakage of soluble hazardous chemicals in small and medium-sized wharves, and belongs to the field of environmental protection and pollution control systems. Background technique [0002] With the rapid development of my country's economy, the waterway transportation volume of hazardous chemicals has increased rapidly year by year; , Hazardous chemical leakage accidents are most likely to occur during loading and unloading; especially when the leaked substances are soluble hazardous chemicals, if they are not contained and treated in time, the consequences of water pollution will be difficult to control and estimate. At the same time, the response to such accidents The processing requirements are higher. [0003] At present, the emergency devices used in wharf leakage accidents are generally oil booms, which are only suitable for the containment and control of insoluble substances such as oi...
