Description

Ship Type Oil Fence Using Electromagnet {SHIP TYPE OIL FENCE USING ELECTROMAGNET}

The present invention relates to a ship-attached oil fence using an electromagnet, and more particularly, to adjust the both ends of the oil fence with an electromagnet to prevent the diffusion of the effluent in the event of an outflow accident of oil and hazardous liquid cargo at sea and in the water surface. The present invention relates to a ship-attached oil fence using an electromagnet for easy installation and easy first aid since it is bonded to the ship itself.

The recent increase in maritime traffic has led to oil spill accidents every year. When oil spills occur, seawater is contaminated by spilled crude oil, and when oil strips reach nearby farms and beaches, various organisms die and cause huge economic losses to the fishermen. .

In particular, large oil spills, such as oil tankers or cargo ships, cause large oil spills. In 2007, the Hebei Spirit accident on the coast of the Taean Peninsula caused a break in the hull due to the collision of oil tankers and barges. It is known as one of the worst oil spill accidents in Korea, where a KL oil spill has occurred.

On the other hand, in general, when an oil leak occurs due to a ship accident or other reasons, it acts as a serious pollutant that pollutes the river or the sea, and thus adversely affects seafood and algae inhabiting the water and destroys the environment. If an oil leak occurs, it is important to prevent the oil from spreading widely and to remove it in a timely manner.

In this case, the oil fence is used. Usually, the oil fence is buoyant by buoyancy body to prevent the spread of harmful oil floating on the sea surface, and the upper part floats on the water surface and the lower part adjusts the buoyancy force. By applying a moderate weight to sink below the surface of the water by placing the oil fence in a direction approximately perpendicular to the sea surface to prevent the spilled oil floating on the surface of the water.

As shown in FIG. 1, the conventional oil fence is provided with a buoyancy body 1 having air or styrofoam embedded therein to obtain buoyancy, and at the bottom thereof to adjust the buoyancy of the buoyancy body 1. A chain 3 is provided for applying a predetermined weight.

The chain 3 is inserted into a pocket formed integrally with the tarpaulin 2, the reference numeral 4, which is not described in the figure, is a shackle used when engaging the connecting ring, and 7 is a towing oil fence. A tripod that is used as an auxiliary device.

On the side end of the oil fence and the tripod (7) is installed a connecting member (5) having a conventional zipper-like structure was used to connect the oil fence and tripod (7) by coupling the connecting member (5) to each other. .

Since the conventional oil fence is not provided with a fixing means, it should be tied using a rope. For example, when the oil is leaked due to the breakthrough of the vessel, as shown in FIG. The oil fence (F) was widely enclosed to surround the ship (S), including the perforated part of the ship (S), and then anchored and fixed by tying the oil fence (F) by connecting a rope. . The anchor is tied in one or two places in the longitudinal direction of the oil fence, and both ends of the oil fence is tied to the deck of the ship and fixed as shown in FIG.

This is because there is no device that can be fixed on the string side of the ship, and there is a bit (pile) to tie the rope of the oil fence on the deck. Both ends of the fence did not come into close contact with the ship, there was a problem that the oil can be leaked to the open area.

In addition, since the oil fence (F) is installed to be approximately perpendicular to the sea surface, the oil fence (F) is not installed in close contact with the curved shape of the ship (S) as shown in Figure 3 ship (S) and oil fence (F) Some gaps could not be prevented in between.

This has been a problem of widening the outflow range of the oil because the oil is continuously diffused into the oil fence (F) surrounded when the hole of the ship (S).

Korean Utility Model Registration No. 20-0221964, Designated "Oil Fence Using Magnetic Force" (Registration date 2001.02.15.)
