Description

Oil and dirt ingress prevention structure {STRUCTURE FOR PREVENTING INFLOW OIL AND RUBBISH}

The present invention relates to a structure for preventing oil and soil inflow, and more particularly, to prevent the inflow of oil on the surface of water and the inflow of algae or soil on the surface of water, and to reduce installation and maintenance time and to reduce costs. It relates to an oil and dirt ingress prevention structure to maximize the utility.

In general, oil spilled on the sea due to stranding of the ship or various sea accidents is spread over a wide range of sea pollution due to waves, etc., so that marine pollution caused by the spilled oil The destruction of the ecosystem causes the loss of fish stocks and the destruction of fish farms or farms, which not only causes huge damage to fisheries but also damages the tourism industry.

In this way, a general oil fence having a function of preventing oil spreading in an oil spill or a risk area or an accident area and helping to recover algae, suspended garbage and contaminants can be installed.

In addition, the oil fence is installed in the river in which the intake port of the intake station is located in order to prevent the oil and floats which may float on the water surface from entering the intake port.

However, the oil fence has a disadvantage in that it can only block oils and other suspended substances having a specific gravity lower than that of water on the surface of water, and cannot block algae under the surface of water.

Therefore, in the related art, separate products having functions of oil shutoff and algae shutoff have a problem in that a large amount of time and excessive cost are generated because they must be separately installed and managed at predetermined intervals on the water surface.

The present invention has been made to solve the above problems, an object of the present invention can prevent the inflow of oil on the water surface and the inflow of algae or contaminants under the water at the same time, reducing the installation and maintenance time and cost To provide an oil and contaminant prevention structure to maximize the utility of.

One aspect of the present invention to achieve the above object, the buoyancy portion is floating on the water surface is a floating body having a circular cross section; A skirt portion connected to the lower side of the buoyancy portion and blocking the inflow of oil on the water surface; A first ballast part installed at a lower end of the skirt part and having a chain embedded therein to keep the skirt part horizontal and stably float on the water surface; It is installed on the lower end of the first ballast portion, the soil blocking portion made of at least one double fiber barrier membrane in order to prevent the inflow of algae or soil under the water surface; And a second ballast part installed at a lower end of the contaminant blocking part and having a chain so that the contaminant blocking part is horizontal and stably floats on the surface of the contaminant.

Here, polyester (PET) fabric is installed to surround the outer peripheral surface of the float; And it is installed to surround the outer circumferential surface of the polyester (PET) fabric, it is preferable to further include a PVC tarpaulin fabric coated with a PVC coating liquid on the surface of the polyester (PET) fabric in order to increase the waterproofness and durability.

Preferably, the double fiber barrier layer of the soil blocking unit may be integrally formed by overlapping a first fiber barrier layer in the form of a cell mesh and a second fiber barrier layer in the form of a hexa pattern.

Preferably, one end of the soil blocking portion, in which one oil and the soil inflow preventing structure is connected to the other oil and the soil inflow preventing structure, in order to prevent the algae or the waste water under the water from counting, is longer than one end of the buoyancy portion. Can be formed.

Preferably, a connection portion is formed at both ends of the buoyancy portion and the soil blocking portion so that one oil and soil contamination preventing structure is connected to the other oil and soil contamination preventing structure.

Preferably, at least one tension belt fixed in the longitudinal direction of the skirt portion or the soil blocking portion may be further provided.

Preferably, at least one auxiliary tension belt fixed to the width direction of the soil blocking portion may be further provided.

According to the oil and dirt inflow prevention structure of the present invention as described above, it is possible to simultaneously prevent the inflow of oil on the water surface and the inflow of algae or dirt on the water surface, and the reduction of installation and maintenance time and cost reduction There is an advantage to maximize the utility.

In addition, according to the present invention, the performance of the oil blocking is continuously maintained by the skirt portion and the ballast portion installed at the bottom of the buoyancy portion even in the state that the algae or contaminants, etc. are collected in the soil blocking portion and the function of the soil blocking portion is deteriorated. There is an advantage to this.
