The inner ring 142 forms an inner part body of the lower frame inner ring 106 and is spaced apart from the outer ring 140 along a circumferential direction at a predetermined interval.

In addition, the inner ring 142 is, for example, is installed in a octagon of the same shape as the outer ring 140, is installed in a somewhat smaller diameter than the outer ring 140, the connection bar 144 is provided on each outer surface By the outer ring 140 is physically connected.

The ring bracket 146 is installed to secure the tightening ring bolt 148 of the lower tightening device 154 to which the fixing member 108 is fixed.

The lower fastening device 154 is installed at each corner of the lower frame inner ring 106 as shown in FIG. 6, and connects the frame 102 and the lower frame inner ring 106 by the fixing member 108. In addition, the fixing member 108 is tightened to reinforce the strength of the frame 102.

Here, the lower tightening device 154 is made of a structure that can withstand the external impact when the frame 102 lands on the sea floor, the tightening direction of the fixing member 108 by the lower frame inner ring 106 described above By concentrating on the central axis of the frame 102, the deformation of the frame 102 can be prevented and the strength can be further improved.

At this time, the fixing member 108 connecting the lower frame inner ring 106 and the frame 102 is the same as the fixing member 108 in the upper tightening device 116, for example, tightening tension and sea water, ultraviolet rays, It consists of a fiber rope or a wire rope which can withstand corrosion enough.

In addition, the lower tightening device 154 is installed to adjust the tension by winding the fixing member 108 connected between the lower frame inner ring 106 and the frame 102.

Here, the lower tightening device 154 includes a configuration of at least one of a tightening ring bolt 148, a tightening ring nut 150, a stop nut 152 and a tightening bracket (not shown).

Tightening ring bolt 148 is disposed in the inner ring 142 along the circumferential direction of the lower frame inner ring 106, and one edge portion is installed as a hook to hook the fixing member 108.

At this time, the fastening ring bolt 148 is installed so that it can be easily replaced according to the length or other conditions of the desired fixing member 108.

In addition, the tightening ring bolt 148 is installed so that the screw thread is formed on the other edge portion to move back and forth by the tightening ring nut 150.

The stop nut 152 is installed to fix the tightening ring nut 150 that moves the tightening ring bolt 148.

Tightening bracket (not shown) is a bracket in which the tightening ring bolt 148 is disposed is installed on the inner ring of the inner ring of the lower frame.

The vertical tightening device 156 traverses the outer surface or the inner surface of the frame 102 in a diagonal direction and is installed to fix the frame 102 in the vertical direction.

Such a frame vertical tightening device 156 performs a vertical structural reinforcement role of the frame 102, and prevents the cage net from being deformed by the algae to cause a volume loss.

At this time, such a frame vertical tightening device 156 is installed on each wall of each frame 102, as shown in Figure 7, for example, the center is provided with a fastening member 164, such as a buckle (buckle) " X "shape.

In detail, this frame vertical tightening device 156 is composed of, for example, four tightening bars 158 and one tightening member 164 as shown in FIGS. 8 and 9, respectively.

As illustrated in FIG. 9, the tightening bar 158 is provided with a tightening bar eye 160 capable of fixing the shackle to one side edge portion, and a thread line at the other edge portion facing the portion where the tightening bar eye 160 is formed. 162 is formed and tightened to the tightening BC nut 166 of the vertical tightening device 156.

The tightening member 164 may include at least one of a tightening BC nut 166, a nut housing 168, an open cover 170, a body 172, an upper cover 174, and a lower cover 176 as shown in FIG. 9. Any one or more configurations are included.

The tightening BC nut 166 is installed inside the tightening member 164 to adjust the length of the tightening bar 158 that is engaged with the tightening member 164.

The nut housing 168 fixes the tightening BC nut 166 in the axial direction of the screw and is installed to rotate in the longitudinal direction of the screw.

The open cover 170 is installed to check and easily observe the interior of the vertical tightening device 156.

In addition, the body 172, the upper cover 174, and the lower cover 176 form a body of the tightening member 164, respectively, and are installed to cover the upper and lower surfaces of the body of the tightening member 164.

Accordingly, the frame vertical tightening device 156 composed of the fastening bar 158 and the fastening member 164 is installed in a plane, thereby preventing the interference with other devices while tensioning, compressing, and leveling the entire frame 102. Strength in the direction can be reinforced.

In addition, when the frame vertical tightening device 156 is installed on the frame 102 by the tightening bar eye 160 and the screw thread 162 described above, the frame vertical tightening device 156 may minimize corrosion in seawater, and the aforementioned one tightening member may be used. By overlapping each of the tightening bar eyes 160 through 164, it is possible to prevent abrasion and to facilitate operation and adjustment of the device.

On the other hand, the reinforcing device for cage culture apparatus according to an embodiment of the present invention is used to reduce the overall weight of the device, the steel pipe is used, such a steel pipe is treated with molten zinc or alum, and a certain amount of anticorrosive zinc is mounted.

As described above, the present invention can reinforce the strength of the frame for cage cage using the upper and lower frame inner ring, the upper and lower fastening device and the fixing member as described above. Due to conditions and red tide, it is possible to prevent damage to the facility or death of farmed organisms as the frame of the cage is automatically settled to a certain water level.

Thus, the present invention may enable stable farming and farming of high value-added fish species.

In addition, the present invention by using only the first and lower frame inner ring, the first and lower fastening device and the fixing member as described above to reinforce the strength of the frame for cage farming device, thereby increasing the weight and manufacturing cost of the structure, and at sea It can overcome the difficulty of maintenance due to the difficulty of transportation, assembly and installation

As described above, the present invention has been shown and described with reference to preferred embodiments, but is not limited to the above-described embodiments and those skilled in the art without departing from the spirit of the present invention. Various changes and modifications will be possible.

1 to 9 is a perspective view for explaining the reinforcement device for cage culture apparatus according to an embodiment of the present invention.
