Description

{DOUBLE-CLIP DEVICE FOR PREVENTING ILLEGALITY TRAWLING ARTIFICIAL FISHING-REEF}

The present invention relates to a double-ring apparatus for illegal fishing-preventing artificial fishes, and more particularly, to a double-ring apparatus for illegal fishing-preventing artificial fishes that can prevent an undersea net used for illegal fishing from being recovered to a fishing boat.

In general, the trawl, that is, the trawler trawl, can be divided into large and medium depending on the size of the fishing boats. The fishing boats are operated as a fishing boats. The fishing boats are principally belonging to the fishing net fishing method, while the fishing boats are operated by using two fishing boats. In English, the former is called danish seine and the latter is called pair trawl or bull trawl. The baseline trawl fishery is licensed under the Fisheries Act, which is divided into large-scale baseline trawl fishery and medium-sized baseline trawl fishery. Permission requirements are set differently depending on fishing boat size and fishing area.

Recently, Chinese fishing boats in the exclusive economic zone (EEZ) of Korea have become a national social issue such as the decrease of fishery resources and the loss of the lives of the crackdown officers due to the continuous increase of illegal fishing using trawlers. With the enactment of the Korea-China Fisheries Agreement in June 2001, the number of catches of Chinese vessels was reduced from about 440,000 tons to about 41,000 tons in 2010 ~ 2012, due to restrictions on spinal numbers and quota of Chinese vessels in our EEZ. This is because illegal fishing vessels in China are increasing rapidly in Korea EEZ due to pollution of Chinese coast and depletion of fishery resources. In addition, illegal fishing vessels show a tendency to scale and collectivization, which limits the illegal fishing line restrictions.

As a result, in order to prevent illegal fishing in the past, it is necessary to eradicate illegal fishing such as negotiation of joint measures to prevent illegal fishing, and Korea has actively illegal fisheries eradication by using artificial fishery to eradicate illegal fishing. There were examples of obtaining effective results.

As a conventional prior art related to artificial fishes, "illegal underwater fishing fisheries aquatic structure" of Patent Publication No. 10-1345819 (2013.12.20) is disclosed. The structure according to the prior art includes a main body that is seated on the bottom of the sea as shown in FIG. 1, and a net engaging portion that is installed on a protrusion of the main body and engages with the net. The net engaging portion is fixed to a protruding portion of the main body. A support rod detachably coupled to the rod, and an engagement member formed on the support rod and engaged with the net. Such a structure was characterized by being installed on the seabed so as to catch the net of a trawler, which catches the fish at random by sweeping the bottom, thereby preventing illegal illegal trawling.

However, the conventional structure could be applied to the net used for the small-scale trawl fishing in the case of the structure that was invented after the fact that the large-sized baseline trawler was greatly reduced as a result of the downsizing business. However, Chinese fishing vessels that engage in illegal fishing are operated with large size, scale, and grouping. Therefore, there is a problem that they can easily escape from the netting portion of the structure by the degree of slight damage to the net using the existing structure.

Further, in the conventional structure, even if a net is caught in the net catch, the net catch can not easily be removed from the net catch because the apparatus and the structure are not provided. Thus, a fundamental solution to the eradication of illegal fishing can not be presented.

In addition, the conventional structure has a problem that since the netting part forms a blade shape, even if the net is caught by the netting part, the caught part is easily broken away from it.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Unless defined otherwise, all terms herein are the same as the general meaning of the term as understood by one of ordinary skill in the art to which this invention belongs, and if the terms used herein conflict with the general meaning of the term Are as defined herein.

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory only and are not restrictive of the scope of the invention, .

The illegal fishing imitation artificial fish second double ring apparatus 100 according to the present invention is a component for preventing the seabed net G used for illegal fishing from being recovered to a fishing boat, that is, illegal fishing boat, (150).

The ring unit 110 is an element for restricting movement by hanging a submarine net G moving along the frame 200 and is provided at a boundary or edge of the sides constituting the frame 200, (200). At this time, a part of the ring unit 110 can be easily integrated with the edge of the frame 200 through a welding method, a bonding method, or a separate fastening method. In the present invention, the ring unit 110 is integrally fixed by welding , This method is a general technique and a detailed description is omitted. Accordingly, since the ring unit 110 is integrated with the frame 200 through the above-described method or the like, it is very easy to install and manufacture the ring unit.

The frame 200 may be classified into concrete, steel, ceramics, and composite materials depending on the material. The frame 200 may be classified into a fish, a tuna, a seafood, And the like, and can be classified into a face structure type, a stem structure type, and the like depending on the structure type.

As shown in FIG. 1, the annular unit 110 is formed by a ring-shaped hook that is opened at one side and is hooked to an inner end of the underside web G through the open side. The ring unit 110 includes the locking part 111 and the needle part 113 as shown in FIG.

The catching portion 111 is a component to which the seabed net G is caught and includes a first end 111a and a second end 111b formed at the opened inner end as shown in Fig.

The first end portion 111a is a component for blocking the movement path of the submarine net G with respect to the entering direction and may be constituted by a catching jaw formed at the opened inner end portion as shown in Fig. The first end portion 111a is connected to a submarine net G moving along one side of the frame 200 in a state where the first end portion 111a faces the direction in which the submarine net G enters, ). The seabed net G is inserted into the hook 111 of the double ring device 100 while moving along one side of the frame 200 and then hooked on the first end 111a blocking the movement path Part of the jaw is caught and movement is restricted. At this time, since the movement of the undersea net G is restricted by the catching jaws, the joint portion of the submarine net G connected to the illegal fishing line is broken and separated from the illegal fishing boat. In other words, illegal fishing boats can not recover the seabed net (G).

The second end portion 111b is a component for blocking the movement path of the submarine net G inserted into the engagement portion 111 with respect to the direction of departure. As shown in Fig. 2, the second end portion 111b extends in the horizontal direction of the first end portion 111a And is provided at one side communicating with the first end 111a. The second end portion 111b is located at the bottom end of the underside net 111b that moves along the first end portion 111a in such a state that the second bottom end portion 111b is opposed to the direction in which the submarine net G is separated from the first end portion 111a, (G). Accordingly, even if the underside net G moves along the first end portion 111a and moves to the second end portion 111b, a portion of the second end portion 111b blocking the movement path is partially caught, do. At this time, since the movement of the undersea net G is restricted by the catching jaws, the joint portion of the submarine net G connected to the illegal fishing line is broken and separated from the illegal fishing boat. In other words, illegal fishing boats can not recover the seabed net (G).

Meanwhile, the first end 111a and the second end 111b are preferably formed as curved arch-shaped wall surfaces. For example, when the first end 111a and the second end 111b form a straight line, the contact area of the submarine net G abutting on the first end 111a and the second end 111b becomes relatively narrower point contact than the curved arch shape. As a result, the stress is concentrated on the narrow contact portion where the first end portion 111a or the second end portion 111b abuts against the seabed web G, so that the seabed web G is gradually cut off from the contact portion where the stress is concentrated , And there is a problem that it easily separates from the engaging jaw through the cut portion. That is, the first end portion 111a and the second end portion 111b are constituted by curved arch-shaped wall surfaces, so that the surface contact with the submarine net G abutting on the first end portion 111a and the second end portion 111b is widened, So that it is not damaged or cut.

The needle portion 113 provides an access passage through which the submarine net G is moved to the hook portion 111 of the hook unit 110 or when the submarine net G entered into the hook portion 111 is connected to the outside, As shown in FIG. 2, and is formed in the shape of a pointed protrusion provided at the end of the fastening portion 111. [0064] As shown in FIG. At this time, the needle portion 113 provides an interval smaller than the thickness of the submarine net G from the frame 200 as shown in Fig. 3 (a). The details of how the submarine net G is inserted into the catching portion 111 of the annular unit 110 through the needle portion 113 and the method of preventing the inserted submarine net G from being released to the outside Details of how to do this will be described later in various embodiments.

On the other hand, the ring unit 110 may further include a guide surface 131.

The guiding surface 131 is a component for guiding a part of the subsea net G moved along the frame 200 to the engaging portion 111. The guiding surface 131 is a portion 113). Specifically, the guide surface 131 has a shape in which the tip of the needle portion 113 is cut in a direction corresponding to the entry direction of the submarine net G. At this time, the incision may take the form of a straight line or a curved line. In the present invention, it is preferable that the incision line has a shape corresponding to the guide 145 described later. The guide surface 131 guides the underside net G moving along the frame 200 to the fastening portion 111 of the ring unit 110 with ease.

On the other hand, the ring unit 110 may further include an induction surface 133. [

The guide surface 133 guides the underside net G to the first end 111a or the underside net G caught in the first end 111a to the second end 111b, As shown in Fig. 2, the first end portion 111a and the second end portion 111b are curved in the form of curved protrusions between the first end portion 111a and the second end portion 111b Respectively. At this time, as the portion of the guide surface 133 bent close to the first end 111a is located on the extension line with respect to the radius of curvature of the access road described later, the underside net G passing through the access road is divided into the first end portion 111a, And may naturally induce the underside net G moved from the first end portion 111a to the second end portion 111b through a portion bending close to the second end portion 111b.

In addition, the ring unit 110 may further include a guide 145.

The guide 145 guides the underside net G moved along the frame 200 from the outside of the annular unit 110 to the engaging portion 111. The guide 145 guides the submarine net G, As shown in FIG. The guide 145 is provided on one side of the skeleton 200 facing the needle portion 113 and is inclined or inclined from the outer side of the needle portion 113 to the inner side of the needle portion 113 And is curved. The guide 145 can guide the underside net G moving along the frame 200 in the direction of the annular unit 110 to the engaging portion 111 naturally.

Further, the ring unit 110 may further include a cut-out portion 110a.

The cut portion 110a is a component for cutting the seabed net G and is formed at the outer end of the annular unit 110 as shown in Fig. It is preferable that the cutting portion 110a has a sharp blade shape in cross section in order to cut a portion of the submarine net G. [ Thus, the cutting portion 110a can easily prevent the illegal trawl fishing by cutting the undersea net G extending out of the annular unit 110 without entering the catching portion 111 described above.

On the other hand, the seabed net G can be easily inserted into the catching portion 111 of the ring unit 110 or prevented from being released to the outside from the catching portion 111, It can be explained in detail by way of examples.

In an embodiment, the ring unit 110 is semicircular as a whole, and can be described by a configuration in which a portion of the needle portion 113 is formed of a material having elasticity so as to achieve a predetermined elastic deformation.

3 (a), when the submarine net G is inserted into the hook 111, the submarine net G, which is moved along the frame 200, A portion of the needle portion 113 is resiliently deformed into the inner space as an external force is applied to the outer surface of the bottom portion 113 so that the submarine net G is provided with an interval at which the submarine net G can enter and exit, And can be easily inserted into the locking portion 111. [

4, when the undersea net G inserted into the catching portion 111 is to be separated from the catching portion 111, the annular unit 110 is pressed against the inner surface of the needle portion 113 by an external force A portion of the needle portion 113 is elastically deformed into the outer space to narrow the width of the access road described above and eventually blocks the access road while being caught by a portion of the guide 145, So that it is prevented from being detached from the engaging portion 111.

In another embodiment, the annular unit 110 can be described by a configuration of a rotating means (not shown) installed in a part of the needle portion 113. [

Such a rotating means includes a rotating member (not shown) and a stopper (not shown).

The tilting member is a component for controlling the entry and exit of the seabed web G and includes a needle portion 113 and an extended end thereof hinged to a part of the end of the hook 111 of the hook unit 110 It accomplishes. The pivoting member can be pivoted inside the latching portion 111 by a predetermined distance about the hinge axis. Thus, when the external force is applied to the tiltable member by the submarine net G, even if the needle portion 113 does not form the elastic material as described above, the trotting unit 110 rotates about the hinge axis, So that it is possible to easily provide an access road through which the submarine net G can be inserted.

The stopper is a component for restricting the turning radius of the tiltable member, and is provided at a part of the end of the ring unit (110). The stopper may form a locking surface at the end of the double ring device 100, and a locking projection abutting the stopper may be formed at the hinge-side end of the pivoting member. Accordingly, the pivoting member is pivotable by the pivoting portion 111 of the pivoting unit 110 on the basis of the installed bar, but is prevented from being moved outwardly of the end of the pivoting unit 110 by the stopper. That is, when the inserted submarine net G is to be released by applying an external force to the inner surface of the pivotal member, the stopper blocks the pivotal movement of the pivotal member by fixing a part of the pivotal member in the locked state, It is possible to easily prevent the light emitting element 111 from being separated from the light emitting element 111.

Accordingly, the annular unit 110 can easily provide an access road through which the submarine net G can be inserted through various methods such as a material for elastically deforming or a rotating means having mechanical characteristics as in the above-described embodiments, It is possible to easily exhibit the locking function that can prevent the undersea net G inserted thereinto from being disengaged from the locking portion 111 without restriction.

The fixing unit 150 is a component for fixing the submarine net G which is caught by the catching part 111 and is limited in movement to the catching part 111 as described above. And over-rotation preventing means 160.

The pressing member 151 is a constituent element for pressing a part of the seabed net G and is constituted by a plate material provided on the lower part or the upper part of the ring unit 110 as shown in Fig. For example, the pressing member 151 may be formed of a material such as rubber or urethane foam having an elastic force.

On the other hand, the urging member 151 can easily provide an elastic force through a torsion spring, a leaf spring, or the like which can be separately provided in connection with the over-rotation preventing means 160, which will be described later. Such a torsion spring or leaf spring is a component for providing a usual elastic force, and a detailed description thereof will be omitted.

The pressing member 151 is hinged at one end to a part of the frame 200 and the other end is installed toward the first end 111a of the engaging part 111 as shown in Fig. Specifically, it is preferable that the pressing member 151 is installed so that the other end thereof blocks the first end 111a of the engaging part 111. [ 3, the pushing member 151 presses a part of the undersea net G into the catching portion 111, and a detailed description will be given later.

The over-rotation preventing means 160 is a component limiting the turning radius of the pressing member 151 described above and includes a rail 161 and a fastener 170 as shown in Fig.

The rail 161 is a component for guiding the pressing member 151 according to the radius of curvature and is provided at a part of the ring unit 110 as shown in Fig. Specifically, the rail 161 has a predetermined radius of curvature in the form of a long hole, and is formed through a portion of the guide 145 described above concentrically with the hinge. The rail 161 is connected to a fastener 170 to be described later to limit the rotation of the pressing member 151 by a radius of curvature.

The fastener 170 is a component that connects the pressing member 151 so as to move along the radius of curvature of the rail 161 and includes an engaging bolt and a latching nut 173 as shown in Fig.

The coupling bolt is a component that moves the pressing member 151 to the rail 161 and moves along the radius of curvature of the rail 161. The coupling bolt may be formed of a conventional bolt or a screw as shown in FIG. The coupling bolt is integral with the pressing member 151 through a part of the pressing member 151 in a state of vertically penetrating a part of the rail 161 as shown in Figure 3 (b) And the one end of the penetrating member is exposed to the outside of the pressing member 151. [ Thus, the engaging bolt restricts rotation of the pressing member 151 only by the radius of curvature of the rail 161, even if the pressing member 151 pivots about the hinge. That is, since the coupling bolt rotates only by the radius of curvature of the rail 161, the pressing member 151 does not deviate greatly from the state in which the first end portion 111a is blocked, Can be sufficiently pressed.

The latching nut 173 is a component for fixing the engagement state due to the fastening bolt 171 described above, and may be constituted by a conventional nut as shown in FIG. 3 (b), the fastening bolt 171 is fastened to the exposed end of the coupling bolt, so that the fastening bolt 171 is fastened to the rail 161 and the pressing member 151). Accordingly, the engagement nut 173 can easily fix the engagement state of the engagement bolt.

The operation of preventing the undersea net G from being separated through the fixed unit 150 will be described in detail as follows.

3, the submarine net G moving along the frame 200 enters the engaging portion 111 by the entrance road, that is, the guide surface 131 and the guide 145, and the guide surface 133 To the first end 111a. At this time, the submarine net G moves between the first end portion 111a and the pressing member 151 blocking the first end portion 111a. Since the pressing member 151 is made of a material having an elastic force as described above, even if the first end portion 111a is blocked, the pushing force of the submarine net G moves The seabed net G can be sufficiently caught by the first end portion 111a through the space between the first end portion 111a and the pressing member 151. As a result,

Next, the pressing member 151 is restored by the elastic restoring force and presses a part of the submarine net G which is contacted through the pushing force (pressure). Accordingly, the seabed net G is partially bent by the pressing member 151 as shown in Fig. 3 (b). That is, the pressing member 151 elastically supports a part of the submarine net G which forms a vertical state, so that a part of the submarine net G is curved, And is fixed to the first end 111a in the engaged state.

3 and 4, the pushing member 151 can more easily fix the undersea net G caught by the first end portion 111a of the latching portion 111 through the over- Since the detailed description thereof is the same as that described above, a detailed description thereof will be omitted.

Therefore, when the submarine net G is caught by the first end 111a of the engaging portion 111, the submarine net G is moved in a direction perpendicular to the first end 111a Direction) can be easily blocked.

In the fixing unit 150, as described above, the submarine net G caught by the first end 111a of the engaging portion 111 is separated from the first end 111a in the vertical direction (up / down direction) It is also possible to prevent the underside net G caught in the second end portion 111b from being deviated in the vertical direction (up / down direction) with respect to the second end portion 111b .

Here, since the detailed structure of the fixed unit 150 is the same as described above, a detailed description of each structure will be omitted, and the structure and function of the fixed unit 150 will be described below.

One end of the pressing member 151 is hinged to the end of the needle portion 113 and the other end is directed toward the second end 111b of the engaging portion 111. [ In detail, it is preferable that the pressing member 151 is installed in a state where the other end blocks the second end 111b of the engaging portion 111. [ This is for achieving a state in which the pressing member 151 presses a part of the submarine net G moved to the second end 111b.

The rail 161 may be formed at a portion of the annular unit 110, preferably at a portion of the needle portion 113, wherein the fastener 170 may be installed with reference to the above.

The operation of preventing the undersea net G from being separated through the fixed unit 150 to be installed will be described in detail as follows.

First, the submarine net G moves from the first end 111a to the second end 111b along the guiding surface 133. [ At this time, the seabed net G moves between the pressing members 151 blocking the second end 111b and the second end 111b. Since the pressing member 151 is made of a material having an elastic force as described above, even if the second end portion 111b is cut off, the pushing force of the submarine net G, The seabed net G can be sufficiently caught by the second end portion 111b after passing between the second end portion 111b and the pressing member 151. [

Next, the pressing member 151 is restored by the elastic restoring force and presses a part of the submarine net G which is contacted through the pushing force (pressure). As a result, the seabed net G is partially bent by the pressing member 151. That is, the pressing member 151 elastically supports a part of the submarine net G which forms a vertical state, so that a part of the submarine net G is curved, And is fixed to the second end 111b in a locked state.

At this time, the pushing member 151 can more easily fix the undersea net G caught by the second end portion 111b of the engaging portion 111 through the over-avoiding turning means, The detailed description thereof is omitted.

Therefore, when the submarine net G is caught by the first end 111a or the second end 111b of the engaging portion 111, the submarine net G is separated from the first end 111a or the second end 111b, It is possible to easily prevent the second end 111b from being displaced in the vertical direction (up / down direction).

Meanwhile, the illegal fishing imitation artificial fish double hook apparatus 100 according to the present invention may further include a reinforcement means 190.
