Description

Antifouling film structure {SILT PROTECTOR APPARATUS}

The present invention relates to an antifouling film structure.

Specifically, when the outer cover is damaged by the external pressure of the ocean (wave force, external force, collision, etc.) in the anti-fouling film, the Styrofoam interpolated inside is scattered in water or wet with water and the load increases. In order to overcome the problem of loss of function, the strength of the outer cover is improved and Styrofoam is changed to a buoyant body made of EPP (Expanded Polypropylene) material to overcome the problem of the existing Styrofoam, and also link the buoyancy body By configuring it to be connected in a positive manner, it relates to a dirt-repellent film structure with superior durability.

Dirty water is inevitably generated when reclamation or dredging works are carried out on the shore, in rivers, or on the seabed. The polluted water generated in this way spreads to adjacent areas, causing environmental pollution and adversely affecting the ecosystem.

In order to prevent such a problem, when dredging works in rivers or the seabed, an anti-fouling film is installed to prevent the filthy water from spreading to the surroundings. The anti-fouling film according to the prior art has a buoy on the top of the canvas made of cloth or cotton, so it takes a long time and increases the cost, as well as the safety accident problem of divers because the divers had to spread the buoy and the canvas directly in the installation area. There is always concern.

In particular, the antifouling membrane may have to be temporarily removed or recovered and then installed again in case of bad weather such as a typhoon.

However, since the antifoam membrane according to the prior art takes a lot of time and money to install and recover, if the Styrofoam is decomposed or floated away due to breakage, recovery is often abandoned. There is a problem that destroys the aquatic ecosystem. In addition, if the antifouling film used once is thrown away, it is another factor of waste of resources and cost increase.

In particular, as the anti-fouling film floats in water for a long time, a part of the anti-fouling film is damaged by the external pressure applied to the anti-fouling film. occurs

As well as. When water flows into the antifoam film, the styrofoam becomes wet with water and the load becomes heavy, and the floating function is lost, and eventually the antifoam film loses its original function.

There is a need for an antifouling film of a new structure that solves these problems.

On the other hand, an anti-fouling film including a reinforcing structure of the film body is described in Korean Patent Registration No. 10-2086076.

The above technology relates to an anti-fouling film comprising a reinforcing structure of a membrane body, and its object is to provide an anti-fouling membrane including a reinforcing structure of a membrane body to prevent the membrane body from being torn at the connection part of the floating body and the membrane body.

To this end, the technique includes a floating body made of a buoyancy-passing connecting membrane; a membrane body having reinforcing bands formed on the upper, lower, left and right sides, and the upper end is sewn to the lower end of the floating body and fixed; and a reinforcing coating layer formed by applying a resin to a reinforcing strip positioned at the connection portion of the floating body and the membrane body after the floating body and the membrane body are connected; a second connecting plate which is installed to be positioned on the reinforcing band formed on the upper side of the membrane body, and is formed with two or more binding holes; a shackle fastened to connect the binding holes of a second connecting plate installed on two adjacent membrane bodies; and an auxiliary connector for connecting the binding holes of the second connecting plate installed on two adjacent membrane bodies at a different position from the shackle; including, wherein the auxiliary connector is a coil disposed between the second connecting plates installed on the two membrane bodies spring; a first fixing plate disposed on one end of the coil spring; a second fixing plate disposed on the other end of the coil spring; a first wire having one end fixed to the first fixing plate and passing through the coil spring and the second fixing plate and fixed to the binding hole of the second connecting plate located on the second fixing plate side; and a second wire having one end fixed to the second fixing plate and passing through the coil spring and the first fixing plate and fixed to the binding hole of the second connecting plate located on the first fixing plate side; It provides an antifouling film comprising a structure.

However, the above-described technology alone cannot expect a clear effect on the prevention of damage, and also cannot cope with the loss of the function of the antifouling film during breakage.

The present invention relates to an antifouling film structure.

Specifically, when the outer cover is damaged by the external pressure of the ocean (wave force, external force, collision, etc.) in the anti-fouling film, the Styrofoam interpolated inside is scattered in water or wet with water and the load increases. In order to overcome the problem of loss of function, the strength of the outer cover is improved by using a tarpaulin material, and the problem of the existing Styrofoam is overcome by changing the Styrofoam to a buoyant body made of EPP (Expanded Polypropylene) material, and also By configuring the buoyancy body to be connected in series, it relates to an anti-fouling film structure with superior durability.

1 shows the antifouling film structure according to the present invention, and FIG. 2 is an enlarged view of area A of FIG. 1 .

The anti-fouling film structure according to the present invention comprises: an outer cover 10 made of tarpaulin material and having improved strength; A plurality of EPP buoyancy bodies 20 accommodated in the outer cover 10 and; a pipe 30 included in the EPP buoyancy body 20; The EPP buoyancy body 20 is configured to protrude on both ends of the eye bolt 40 coupled to the pipe 30; A plurality of EPP buoyancy bodies 20, a connector 50 for physically connecting the eye bolts 40 between adjacent ones; is configured to include.

At this time, the EPP buoyancy body 20 has an EPP (Expanded Polypropylene, expanded polypropylene) material.

In addition, the pipe 30 is a material obtained by performing ZFC-TOP coating on a steel material, and has strong resistance to seawater immersion and salt spray. That is, corrosion does not occur.

The pipe 30 is included in the through hole penetrated in the longitudinal direction of the EPP buoyancy body 20, and the pipe 30 is configured such that the inside is hollow and threads are formed on the inner surfaces of both ends.

Accordingly, a part of the eye bolt 40 is interpolated into the through hole of the EPP buoyancy body 20 and is fastened to the pipe 30 using a thread formed at the interpolated end.

In addition, the connector 50 includes two coupling rings 51 as shown in FIG. 2 of the accompanying drawings; It connects between the two coupling rings 51 and includes a connecting rod 52 integrally formed with the coupling ring 51.

In this case, the coupling ring 51 has the shape of a conventional ring or ring, and the specific shape may be clearly designed by a person skilled in the art.

However, it is sufficient if the coupling ring 51 can be coupled to the ring portion of the eye bolt 40 .

According to the anti-fouling film structure configured as described above, the strength of the outer cover 10 is improved and the possibility of damage due to external pressure is reduced, thereby improving the durability of the anti-fouling film.

In addition, even if the outer cover 10 is damaged, it is not a conventional Styro product but a buoyant body made of EPP material, so it is possible to prevent scattering into the sea, and the volume and load are reduced even if the EPP buoyancy body 20 contains water. increase can be prevented.

However, depending on the design conditions, by configuring the connector 50 as shown in [Table 1], a plurality of EPP buoyancy bodies 20 coupled through the connector 50, for example, of the outer cover 10 Even if the load is increased in one direction due to damage and it is inclined in the water, it can be easily returned to its original position by wave force or the like.

The connecting body 50 according to [Table 1] configures the connecting rod 52 for connecting the above-described coupling ring 51 as follows.

The connecting rod 52 is integrally formed from one side of the coupling ring 51 and extends with a cover (52a); It includes; an insertion rod (52b) extending integrally formed from the other side coupling ring (51).

The cover 52a includes a groove formed concavely from one surface opposite to the coupling ring 51 on one side, and the protruding rod 52a2 protrudes from the innermost wall of the groove portion to extend. However, the protruding rod 52a2 is to protrude smaller than the groove portion.

In addition, a plurality of inclined grooves 52a1 having an inner wall direction in a straight direction and inclined in an open direction of the groove portion may be formed as a side wall of the groove portion at regular intervals.

In addition, the insertion rod (52b) is configured to be inserted into the groove portion of the cover (52a), the inclined projection of the shape corresponding to the inclined groove (52a1) on one side of the outer surface is configured to protrude.

In addition, a concave second groove portion 52b1 is formed on one surface of the insertion groove 52b, and the second groove portion 52b1 allows the protrusion rod 52a2 to be inserted.

At this time, a spring is coupled from one surface of the protruding rod 52a2 to the inner wall surface of the second groove portion 52b1. Here, coupling refers to all couplings that enable coupling of springs, such as welding, attachment, and bolting.

In addition, from the inner wall surface of the groove portion at a position avoiding the position of the protruding rod 52a2, the direction retaining spring having the shape of a coil spring is also provided on one side of the insertion rod 52b closest to the inner wall surface of the groove portion by the eyebolt. It may be configured in a coupled state, at this time, the direction retaining spring is coupled to the inclined groove (52a1) as far as possible from the inner wall surface of the groove portion, and in the protruding rod (52a2) to the inclined groove (52a1) or the inclined projection. It is configured to be coupled to the nearest position.

Therefore, the direction maintaining spring is coupled to have an inclined direction as shown in [Table 1].

According to this, even if the two adjacent EPP buoyancy bodies 20 are not positioned on a straight line and are bent, for example, the EPP buoyancy body coupled to the other side coupling ring direction for reasons such as the outer cover 10 being damaged or the like due to external pressure In the case of bending, bending and stretching are possible due to the elasticity of the springs, so that the inclined protrusion is fixed in the inclined groove, and the insertion rod 52b is inserted in the cover 52a despite a small external pressure due to the elasticity of the direction retaining spring. Since the return action is possible, it is possible to return to the original state of the connector 50 due to a small external pressure such as wave force, thereby preventing damage such as disconnection of the connection between the EPP buoyancy bodies 20 .

Conversely, when bending occurs in the direction of one coupling ring, the insertion rod 52b has a size that is tightly fitted so that it cannot be bent in the groove portion of the cover 52a due to the inclined protrusion configuration, thereby preventing bending.

What has been described above using the drawings is to describe only the main points of the present invention, and as many designs are possible within the technical scope, it is obvious that the present invention is not limited to the configuration of the drawings.
