Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an air expanding type oil fence,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an air inflated-type oil fence, and more particularly, to an oil fence having an inflatable shape retaining structure. More specifically, the oil fence inflated by inflating compressed air maintains its shape firmly, To an air inflated shape retaining oil fence which can be easily used at high waves and installed on both sides of a ship and a guard box so as to prevent the spread of oil spilled on the sea and to collect it quickly.

In general, an oil fence is a device for preventing or collecting oil spilled from the water when the oil is leaked due to marine accidents or the like. It is a high-type oil fence that is covered with oil retaining oil and air There is an inflatable oil fence.

The oil fence is mainly used as an air inflating oil fence rather than a high type when a large-scale spreading is concerned or quick action is required. Here, the air inflating oil fence surrounds the sea to prevent the spread of the oil flowing out to the sea. It is composed of float and skirt of about 30cm above the sea surface and about 40cm below the sea surface. It is used not only to prevent the spread of oil spill if it occurs, As measures against oil spillage, oil fences may be installed to surround ships and mooring facilities.

However, in order to prevent the oil fence from collecting or spreading oil during oil spillage, the vessel must be fixed at a fixed position and the work process must also adjust the oil fence using manpower, so that the time, cost and manpower And it is difficult to effectively prevent the oil moving along the sea surface.

However, the present air injection is performed swiftly and the expanded oil fence keeps its shape firmly, so that it can be easily used even at a high wave. It is installed on both sides of the ship and guard box definition, The need for an oil fence capable of minimizing the purchase cost of the ancillary equipment for the use of the oil fence has been actively researched.
