Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a jointing device for connecting pipes in a cage frame, and more specifically to a jointing device that can easily and firmly connect pipes together.

<Conventional technology> Currently, fish cages for various types of marine aquaculture are
It is framed by pipes on all sides, a wire mesh is placed around the framed pipes, a buoy is attached to the pipes, and the pipes are floated and stationary on the sea. By connecting the pipes framed in each of the above, This system enables large-scale fish farming to be carried out safely and efficiently.
Normally, pipes are tied together with ropes, etc., but there are always waves at sea, and the waves gradually loosen the ropes, which can cause pipes to come into contact with each other and be easily damaged. Ropes, etc. must be re-tightened at regular intervals, which is often very time-consuming, and in the case of bad weather such as typhoons, the direct load on the ropes can cause the joints to break, resulting in major damage. There were many.

<Problems to be Solved by the Invention> The present invention attempts to solve the above-mentioned drawbacks of loosening of ropes, etc. due to wave motion, and damage to pipes, by a simple method without using ropes, etc.

<Means for solving the problem> The gist of the present invention is to align two semicylindrical fixture bodies, each with a built-in reinforcing core and flanges on both sides, so that their flat surfaces are in contact with each other. two grooves are bored in the flat surface of each of the fixture bodies so that two cylindrical through-holes are formed adjacent to each other along the longitudinal direction inside the fixture; A rope fastening part with a rope insertion hole of the required diameter is provided on the outer periphery of either side of the main body, and a rope fastening part with a rope insertion hole of the required diameter is provided inside, and the flange of the above-mentioned fixture main body is provided with a rope fastening part for attaching a fastening device such as a bolt. This is a frame fixing device for a cage, characterized by having a binding device insertion hole formed therethrough.

<Embodiments and operations> The cage frame fixing device according to the present invention will be described in detail below with reference to drawings showing embodiments thereof.

FIG. 1 is an explanatory cross-sectional view of the present invention, in which a reinforcing core bar 1 is made of an elastic material (such as rubber) and is built into the outer periphery of a semicylindrical fixture body 3 having flanges 2 on both sides. When the two semicylindrical fixture bodies 3 and 3' are placed facing each other with their flat surfaces abutting each other as shown in FIG. Two frame body insertion grooves 5, 5, 5' are formed on the flat surface of each of the above-mentioned cupped fixture bodies 3, 3' so that the frame body insertion holes 4, 4' are formed adjacent to each other. 5' is perforated. Then, on the outer periphery of one of the two semicylindrical fixture bodies 3, 3',
A rope insertion hole 6 of a required diameter is formed inside to form a rope fastening part 7 into which a reinforcing core bar 1 is protruded and built-in, and the collar parts 2, 2, 2', 2' are provided with a required number of fastener insertion holes 9 so that the cage frame can be fixed by attaching fasteners 8 such as bolts.

FIG. 2 is an overall explanatory diagram showing the state of use, and shows a framework for fish cages in which a wire mesh 11 is provided around the inner frame 10 and a plurality of buoys 13 are further arranged between the outer frame 12 and the inner frame 10. A, A... In order to connect the comrades, the pipe-shaped outer frame 1 of each of the above fish cage frameworks A, A...
The pipe-shaped outer frames 12, 12 are fitted into the frame insertion grooves 5, 5, 5', 5' of the semicylindrical fixture bodies 3, 3' at several locations 2, 12 to fasten the bolts, etc. As shown in the enlarged view of the main part in FIG. By fastening them together, the connection can be maintained completely without coming loose even if a large force is applied from the outside. The elastic body on the outer circumferential surface of the semicylindrical fixing body 3, 3' is used to prevent rust and damage to the built-in reinforcing core 1, and also to prevent damage to the reinforcing core 1. The elastic body is the pipe-shaped outer frame 12,1.
2 without contacting each other, and absorbs external shocks.
It is for protecting the frame bodies 12, 12,
As for the material, a material that is somewhat hard and tough for the outer circumferential portion and a flexible material for the inner circumferential portion is suitable.

<Effects of the invention> According to the invention, by connecting the fish cage frames to each other using the fish cage frame fixing device, the frame joints will not loosen due to constantly generated waves, and large external forces will not act on them. However, since the impact force is absorbed by the elastic body around the joint, no force is applied to the frame itself and the frame can be protected. In addition, in connection work, it is easier to install and takes less time than conventional methods, and is very economical.Furthermore, it can be installed quickly in an emergency, and has great effects.
