Description

Fish cage

The invention relates to a fish cage.

Usually, in order to catch fish that live in the sea or rivers, fish gills, nets, fish cages, etc. are used. Among them, fish catches in fish cages are larger than fish catches in fish gills, and fish cages are also simpler to use than fishing nets.

The fish cage as described above has various forms and structures, and an example of a fish cage is disclosed in Korean Utility Model Publication No. 1994-0000778.

1 is a view showing an example of a spring fish cage in a conventional fish cage, and FIG. 2 is a view for explaining a method of recovering fish caught by a fish cage.

The existing fish cage 10' includes: a frame 12P composed of a cylindrical disc spring; a fish cage net 11P surrounding the frame 12P, forming an inlet 11Pa, 11Pb; and an attraction portion 13 extending from the inlet 11Pa, 11Pb toward the fish The center of the cage extends in the direction of the center.

The fish 5 enters the first attraction portions 13aa and 13ba through the entrances 11Pa and 11Pb on both sides, and passes through the attraction frames 13a' and 13b' that support the one end portions of the first attraction portions 13aa and 13ba. Further, the fish 5 passes through the attracting ports 13a" and 13b" of the second attracting portions 13ab and 13bb, and is finally captured by the fish cage 10'. The second attracting portions 13ab and 13bb are formed with the first attracting portions 13aa and 13ba. One way, one end with the above The first attracting portions 13aa and 13ba are connected to each other, and the second attracting portions 13ab and 13bb extend in a shape having a diameter smaller than that of the first attracting portions 13aa and 13ba. The captured fish 5 is stored in the storage unit 14, and a fishing lure (not shown) can be placed in the storage unit 14 as described above to attract fish. When the fishing is completed, the fish cage 10' is hollowed out on the land, the fish 5 is taken out from the storage portion 14, and after the force F is applied to the fish cage 10' to crush the fish cage 10', the fish cage fixing portion 15P is fixed. Both sides of the frame 12P of the fish cage 10' are stored and stored.

However, in the conventional fish cage 10', the fish 5 stored in the storage portion 14 easily escapes from the plurality of attracting portions. In other words, when the fish 5 is in the process of swimming in the storage unit 14, if it is close to the attraction ports 13a" and 13b", it is easy to escape to the outside of the fish cage 10'. Therefore, there is a problem that the amount of catch of the fish 5 is reduced.

Further, in the conventional fish cage 10', there is a problem that foreign matter such as garbage or jellyfish flows into the fish cage 10' through the inlets 11Pa and 11Pb. When the garbage or the like flows into the inside of the fish cage 10', it is spoiled inside the storage portion 14, which makes it difficult to catch the fish 5 by the fishing lure. Since the caught fish 5 is killed by foreign matter such as garbage, there is also a loss of the fish 5 Sexual anxiety. Further, if the jellyfish or the like flows into the inside of the fish cage 10', the jellyfish will kill the fish 5, resulting in a decrease in the amount of fishing.

Fig. 3 is a view showing an example of a cylindrical fish cage of an embodiment.

Referring to FIG. 3, the fish cage may include a fish cage net 10, a frame 20, an attraction portion 30, and an escape prevention portion 100.

The fish cage net 10 can be in the form of a mesh. According to this embodiment, the fish cage web 10 can be supported by the frame 20 and form an interior space. For example, as shown in FIG. 3, the end of the fish cage net 10 is connected to the annular frame 20, thereby forming a cylindrical fish cage, so that a space for catching the fish 1 can be formed inside the fish cage. An inlet 11 for allowing the fish 1 to flow into the fish cage net 10 can be formed, and the attraction port 12 can be formed in the attraction portion 30, and the fish 1 flowing in through the inlet 11 can enter the internal space of the fish cage through the attraction portion 30. In order to position the lure port 12, the lure portion 30 is positioned in the fish cage net 10 by means of at least one or more connecting members. For example, the attraction portion 30 can be bundled on the upper side and the lower side of the fish cage net 10 by at least one or more string members S to fix the attraction portion 30. For example, the frame 20 may include an annular first frame 21 and a second frame 22 that are disposed with a predetermined distance apart in the up and down direction. The frame 20 is formed of a metal material, and may be coated with a resin material or the like in order to prevent corrosion. Alternatively, it may be made of a variety of materials such as synthetic resin instead of metal.

On the other hand, the shapes of the first frame 21 and the second frame 22, as shown in FIG. 3, may be annular with the same size (for example, diameter), as shown in FIG. 4, may be square, as shown in FIG. The diameters of the first frame 21 and the second frame 22 may also be different from each other. This can vary depending on the environment in which the fish cage is used. The frame 20 is combined with the fish cage net 10 to form the structure of the fish cage so that a variety of shapes can be formed as desired. For example, the first frame 21 and the second frame 22 may be variously formed in a circular shape, a polygonal shape such as a triangle or a square.

The attraction portion 30 extends from the inlet 11 of the fish cage net 10 in a direction toward the inside of the frame 20, and the attraction portion 30 may include the attraction opening 12. As shown in FIGS. 3 to 5, one attraction portion 30 may be disposed on one side wall surface of the fish cage net 10, but is not limited thereto. That is, as shown in FIG. 6, when the pair of inlets 11a and 11b are respectively formed on the opposite side and the other side of the fish cage net 10, the pair of attraction portions 30a and 30b, that is, the first attraction portion 30a and The second attracting portion 30b can be disposed in a relative manner, and as shown in FIG. 7, a plurality of attracting portions 30a, 30b, and 30c can be further provided. The number of the attracting portions 30 may vary depending on the size of the fish cage and the size of the fish to be caught. As shown in FIG. 3, the attraction portion 30 is connected to an inlet 11 formed on a side wall surface (side surface) of the fish cage net 10, and the diameter of the attraction opening 12 is smaller than the diameter of the inlet 11, thereby gradually narrowing in the direction of extension. . With the attraction portion 30, the fish 1 can be attracted to the inside of the fish cage. The fish cage net 10 is combined with the first frame 21 and the second frame 22 to form an upper surface, a lower surface of the fish cage, and side surfaces for connecting the upper and lower faces of the fish cage. In Fig. 3, the upper and lower faces of the fish cage exhibit circular planes corresponding to the shapes of the first frame 21 and the second frame 22, and the sides of the fish cage are curved. As shown in FIG. 4, the upper and lower faces of the fish cage exhibit a square plane corresponding to the shapes of the first frame 21 and the second frame 22, and the sides of the fish cage include four square planes.

The escape preventing portion 100 may form a separate space for at least one fish passing through the hole 110 and at least one outlet 120 for discharging the fish 1 through the fish of the attracting opening 12 of the at least one attracting portion 30 to form an escape preventing escape Department 100.

As shown in FIG. 3, the escape preventing portion 100 may be spaced apart from the attracting portion 30 by a predetermined distance g. Since the distance g is smaller than the size of the fish 1, the fish 1 passing through the attracting port 12 cannot escape from the gap between the attracting portion 30 and the escape preventing portion 100. Even if you escape, it is not in the interior of the fish cage. through The fish 1 that has flowed in through the attracting portion 30 passes through the attracting opening 12 and flows into the internal space of the escape preventing portion 100 through the fish passage hole 110, and the fish 1 that has flowed into the escape preventing portion 100 can be discharged through the outlet 120 and housed inside the fish cage.

The escape preventing portion 100 can take on a variety of shapes. For example, as shown in FIG. 3, the escape preventing portion 100 may be substantially cylindrical. For this purpose, a pair of annular frame sleeves may be connected to the Internet, and a fish passage hole 110 may be formed on the side surface to form one of the upper surface or the lower surface. The outlet 120 is formed to create the escape preventing portion 100. The escape preventing portion 100 can be positioned by binding the escape preventing portion 100 to the fish cage net 10 by using at least one or more connecting members such as a rope member S or a bar.

As shown in FIGS. 3 and 4, the escape preventing portion 100 may be disposed in a direction perpendicular to the extending direction of the attracting portion 30, that is, erect in the interior of the fish cage in a direction perpendicular to the moving direction of the fish. As shown in FIG. 5, the escape preventing portion 100 may be disposed in a direction substantially perpendicular to the moving direction of the fish, or may be disposed in parallel with the bottom surface of the fish cage. The arrangement position of the escape preventing portion 100 in this manner may vary depending on the structure and design of the fish cage. In the escape preventing portion 100 as described above, the fish passing through the hole 110 and the outlet 120 are spaced apart from each other in a direction different from each other. For example, fish can be perpendicular to each other through aperture 110 and outlet 120.

Fig. 6 is a view for explaining an example in which a pair of attracting portions 30a and 30b are provided in a cylindrical fish cage according to an embodiment. The first inlet 11a, the second inlet 11b, the first attracting opening 12a, and the second attracting opening 12b may be respectively disposed in each of the attracting portions 30a and 30b. The first inlet 11a, the second inlet 11b, the first attracting opening 12a and the first The two attracting ports 12b can be symmetrically arranged in the same shape. However, the present invention is not limited thereto, and may be disposed in a plurality of positions as needed.

In the case where the fish cage has a pair of attracting portions 30a, 30b, the escape preventing portion 100 can be from one portion of the one side attracting portion to the other side attracting portion It is arranged such that it is surrounded by the whole part of the attraction part. That is, as shown in FIG. 6, the escape preventing portion 100 can be formed by surrounding the first attracting opening 12a and the second attracting opening 12b by the mesh member. The first attracting opening 12a and the second attracting opening 12b surrounded by the escape preventing portion 100 can be disposed in a opposed manner. Therefore, the pair of attracting portions 30a and 30b can be connected by the string member S to perform positioning. In the escape preventing portion 100 as described above, the outlet 120 may be disposed at a position perpendicular to the first attracting opening 12a and the second attracting opening 12b. Also, one or a plurality of outlets 120 may be formed.
