BEST MODE FOR CARRYING OUT THE INVENTION First, based on FIGS. 1 to 4,
The water bottom submerged member 2 constituting the artificial fishing reef 1 according to the embodiment of the present invention will be described. The water bottom submerged member 2 constituting the artificial fishing reef 1 according to the embodiment of the present invention includes the through hole 3
A natural stone 4 or a plurality of natural stones 4 which are formed, a connecting member 5 which is inserted into the through hole 3 of the natural stone 4 to connect the natural stone 4 or a plurality of natural stones 4, and is connected to both ends of the connecting member 5. And a hook-shaped member 6.

A natural rock is used as the natural stone 4. If the size of the natural stone 4 is too small, it tends to be swept by the flow of water, and if it is too large, it is difficult to carry, install, move, etc.
It is preferable to use the thing of about m. However, the size of the natural stone 4 is not necessarily limited to this, and it is possible to select and use an appropriate size according to the installation place, the application, etc.

The shape of the natural stone 4 is not particularly limited, and rocks of various shapes can be used. Since the water bottom submerged member 2 is used as a part of the artificial fish reef 1 according to the embodiment of the present invention, rocks having a large number of irregularities on the surface are preferable because water grass, sea grass, etc. are more likely to adhere to them. Since a single or a plurality of the natural stones 4 are connected to each other and unevenness is always formed in the gaps between the adjacent natural stones 4 or the like, even in this case, the surface is relatively uneven. Rocks with a smooth surface can also be used.

There is no particular limitation on the number of the natural stones 4 used per one of the water bottom submerged members 2, and one or more natural stones 4 can be connected according to the length of the connecting member 5. is there. However, when the number of the natural stones 4 is too large, it is difficult to carry, install and move the same as when the size of the natural stones 4 is too large.
It is preferable to use about 20 to about 20 pieces, and to appropriately connect a plurality of the water bottom submerged members 2 as needed. The connection between the water bottom submerged members 2 can be easily performed by using the hook-shaped members 6 connected to both ends of the connection member 5.

The through holes 3 are formed in each of the natural stones 4. The through hole 3 is provided for inserting the connecting member 5 therein, and naturally has an inner diameter larger than the diameter of the connecting member 4. The position where the through hole 3 is provided in the natural stone 4 is usually a position passing through the center of the natural stone 4. However, the position where the through hole 3 is provided is not necessarily limited to this, and it may be formed near the end of the natural stone 4.

The connecting member 5 is a member that is inserted into the through hole 3 of the natural stone 4 and connects one or more natural stones 4 to each other. The connecting member 5 is made of a material that is not destroyed by the weight of the natural stone 4 or friction with the natural stone 4, for example, a long metal rod having a constant diameter, In particular, it is preferable to use a stainless rod in consideration of corrosion resistance and impact resistance.

The length of the connecting member 5 is set to a length equal to or longer than a length at which the hook-shaped members 6 can be connected to both ends in a state where all the natural stones 4 to be used are connected. Here, by setting the length of the connecting member 5 to be long, it becomes possible to arbitrarily widen the intervals between the natural stones 4 when the water bottom submerging member 2 is arranged on the water bottom. . As a result, the gap between the adjacent natural stones 4 becomes variable, so that even if the seawater bottom has irregularities, it can be bent along the irregularities and can be installed stably. .

Further, as shown in FIG. 5, a flexible string-like connecting member 5 may be used in place of the rod-like connecting member 5 described above. In this case, as the connecting member 5,
It is possible to use a material that is not cut by the weight of the natural stone 4 or friction with the natural stone 4, for example, a metal wire, a chain, a rope or the like,
It is preferable to use a stainless wire in consideration of corrosion resistance and durability. The diameter of the string-shaped connecting member 5 is set to a diameter that can ensure the necessary strength depending on the material used. Further, although not shown, when the string-shaped connecting member 5 is used as described above, it is possible to fold the end portion into a ring shape and fix it with a predetermined fastener or the like. .

The hook-shaped members 6 are connected to both ends of the connecting member 5, respectively. The hook-shaped member 6 prevents the natural stones 4 connected by the connecting member 5 from coming off from the end of the connecting member 5, and the water bottom submerging member 2 is an artificial fish reef according to an embodiment of the present invention. Since it is used as a part of 1, it is provided to connect the water bottom submerged members 2 to each other. The hook-shaped member 6 has a shape that can be hooked with each other, such as a C-shape or a U-shape. The hook-shaped member 6 is made of, for example, stainless steel in consideration of corrosion resistance and the like. The hook-shaped member 6 and the connecting member 5 are coupled to each other so that the coupling cannot be easily released. Here, as shown in FIG. 3, male threads are formed on both ends of the connecting member 5, and female threads are formed on the coupling portion 7 of the hook-shaped member 6 so that they are coupled to each other by screwing. The method of connecting the hook-shaped member 6 and the connecting member 5 is not limited to this, and it is also possible to connect them by other methods such as welding or fastening using bolts and nuts. is there.

Further, as shown in FIG. 6, the hook-shaped member 6
Instead, the locking member 8 having an outer shape larger than the inner diameter of the through hole 3 of the natural stone 4 may be coupled to both ends of the connecting member 5. Even if the hook member 6 is not provided in the locking member 8, the natural stone 4 is used as the connecting member 5.
It is provided in order to prevent it from coming off from the end of the. Therefore, the shape and the material of the locking member 8 are not particularly limited, and the locking member 8 has an outer shape larger than the inner diameter of the through hole 3 of the natural stone 4 in the direction orthogonal to the length direction of the connecting member 5. Any shape and material can be used. Here, as an example, a male screw formed at both ends of the connecting member 5 is screwed with two metal nuts. Note that the locking member 8 can be joined by another method such as welding as with the hook-shaped member 6.

According to the artificial fishing reef according to claim 3 of the present invention, in addition to the effect of the artificial fishing reef according to claim 1 of the present invention described above, since the metal member is a constituent element of the artificial fishing reef, it is resistant to corrosion. Also, it has excellent impact resistance and the like, and can be used for a long period of time because it does not change over time.

According to the artificial fishing reef of claim 4 of the present invention, in addition to the effect of the artificial fishing reef of claim 1 of the present invention described above, a metal plate is used as a constituent element of the artificial fishing reef.
The buoyancy of the thinned timber that constitutes the artificial fishing reef can be reduced. Therefore, even if the thin timber or the screw connecting the thinned timber with a metal plate is corroded, the artificial fishing reef does not float on the sea surface.

According to the artificial fishing reef according to claim 5 of the present invention, in addition to the effect of the artificial fishing reef according to claims 1, 2, 3 and 4 of the present invention described above, a long member and a water bottom submerged member are provided as well. Since they are combined and stacked in a polygonal shape, they are excellent in downsizing and weight saving, and can be easily installed even in shallow and shallow seawater bottoms. In addition, since the connecting member that constitutes the submerged member has a certain degree of elasticity, even if there is unevenness on the seabed, the entire artificial reef will bend accordingly, so it adapts to the seabed and is stable. Can be installed in

According to the artificial fishing reef according to claim 6 of the present invention, in addition to the effects of the artificial fishing reef according to claims 1, 2, 3, 4 and 5 of the present invention, thinning is performed between natural stones. Since the water bottom submerged member that can arrange the material and keep the interval between the natural stones constant is a constituent element of the artificial fishing reef, the length and shape of the water bottom submerged member can be easily adjusted,
Therefore, the size and shape of the artificial reef can be easily adjusted. In addition, since thinned wood easily attaches to algae, by alternately arranging with natural stones to which water plants and seaweeds tend to attach, it is possible that both waterweeds and seaweeds and algae attach favorably to the entire submerged member. Therefore, an artificial fishing reef that can collect various seafood can be easily installed.
