JPS603140Y2 - oil fence - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to an improvement of an oil boom.

Oil fences are used to prevent the spread of oil spilled from land tanks, ships, etc. onto water such as seawater, and to collect it.

Generally, this oil fence has a floating body part 1 as shown in Fig. 1.
and a skirt portion 2.

In addition, 11 and 12 in FIG. 1 form floating body parts, respectively.
Cloth membrane body for floating body and floating body, 21, 22, 23, and 24 respectively indicate a cloth membrane body, a weight, a tension holding portion, and a tension holding portion cover, which form a skirt portion.

Conventionally, the cloth membrane forming this skirt portion cloth membrane body was, for example, a third cloth membrane.
As shown in the figure, there is a cloth 5' in the center with rubber or plastic layers 8, 8' forming the surface above and below it.

In conventional oil fences of this type using cloth membranes in the skirt portion, when used permanently in the sea, shellfish such as oysters adhere to the underwater portion (skirt portion), which poses a practical problem.

Conventionally, as a method for preventing oysters and the like from adhering to structures in ice, a sheet in which a toxic substance for preventing adhesion of aquatic organisms is directly mixed with a synthetic resin has been used, as described in Japanese Patent Publication No. 36-6788.

However, mixing toxic substances with synthetic resin in this way poses a great risk of being dispersed into the air or coming into direct contact with workers during work such as handling and mixing the toxic substances, and it is considered harmful to the human body. Moreover, when such materials are mixed with synthetic resins, the strength often decreases, and physical properties are also unfavorable.

The present invention focuses on the principle that copper ions are effective in preventing the adhesion of shellfish, and the above-mentioned problem has been solved very simply by having the membrane in the part of the oil fence that is immersed in water have cloth and by using copper wire. be.

That is, the present invention provides, for example, in an oil fence constituted by a floating body part 1 and a skirt part 2 as shown in FIG. It is characterized by consisting of a copper wire woven fabric and a rubber or plastic layer.

In FIG. 2, the cloth membrane has a rubber or plastic layer 8 in the center that prevents spilled oil from penetrating through the cloth, which will be described later. 0.0
3 to 0.171771φ) is incorporated.

As a result, copper ions are generated from surfaces directly exposed to water such as seawater, thereby preventing the adhesion of shellfish such as oysters.

In the above explanation, the cloth membrane of the part immersed in water is used as an example to form a skirt cloth membrane body, but the present invention is not limited to this. It may also be a cloth membrane.

As described above, by employing the structure of the present invention, an oil fence that is excellent in preventing oyster adhesion can be obtained without the problems of toxicity and problems with strength and physical properties unlike conventional oil fences.
