Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a float rope, and more specifically, it is used while floating on the water surface, such as a rope for setting up a seaweed cultivation net or a course rope for a competitive swimming pool. Regarding rope.

(Conventional technology) The net used for seaweed cultivation is a rope with a float or buoy attached to it tied to a stake driven into the seabed and floated on the sea surface, and the net is stretched between two parallel ropes to cultivate seaweed. It is something to do.

By the way, floats are attached to the two ropes on which the net is stretched horizontally along the length of the ropes in order to float them on the sea surface. The leaves that have grown on the nets are then harvested from mid-November until the end of March or mid-April the following spring. After harvesting, the nets, ropes, etc. are removed from the sea surface, washed, and stored.

However, since the ropes used to stretch the nets are made of hemp or synthetic fibers, they are very heavy and difficult to handle, and the work of stretching the nets is hard labor. In addition, the buoyancy that floats the rope on the sea surface is adjusted by the number of floats or buoys attached to the rope, but it takes time to attach and detach the buoyancy and buoys, and there is a step between the float and the rope, causing the rope to It will sink below the sea surface.

Additionally, since it is difficult to confirm the presence of aquaculture nets at night, an accident may occur if a ship passes over the aquaculture nets and cuts the ropes or nets. The problem is that it is very difficult to install or apply luminous paint to the rope.

The present invention has been made in view of the problems of the prior art, and aims to be lightweight, easy to handle, able to freely adjust buoyancy, and easy to identify. To provide a float rope to which means can be easily added.

(Means for Solving the Problems) In order to achieve the above object, the float rope of the present invention has a hollow flat rope body formed to a predetermined length, and the left and right sides thereof are sealed with a synthetic resin material and a reinforcing material. to form an air chamber, and provide air plugs at predetermined locations on the circumferential wall of the air chamber, as well as joints with reduced outer diameters at predetermined width intervals along the longitudinal direction, and are connected to the outer periphery of the left and right sides of the rope body. It is made by fixing a ring.

As the reinforcing material embedded within the molded thickness of the synthetic resin material, such as vinyl chloride resin, constituting the rope body, warp yarns and braids along the longitudinal direction are effective.

Further, the outer peripheral surface of the rope body may be coated with luminous paint for identification at night, or may be engraved or marked as an identification mark of the owner.

(Function) According to the above means, by connecting a pump to the air plug and injecting air, the rope body expands to have a circular cross section and becomes a float rope that floats on the sea surface. The buoyancy can be freely adjusted by adjusting the amount of air injected into the air chamber of the rope body, and joints with reduced outer diameters are formed at predetermined intervals in the longitudinal direction of the rope body. Therefore, the rope has excellent flexibility, and if a string for laying a net or the like is tied to its joint, the string will not move laterally and will be held in a fixed position. If a luminescent paint is applied to the outer circumferential surface of the rope body, the rope will be illuminated at night to clearly indicate the presence of the rope.

Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings. A is a rope body made of vinyl chloride resin 1 and formed hollow and flat to a predetermined length (for example, 10 m, 20 m). Warp threads 2 made of vinylon yarn with little elongation are embedded along the longitudinal direction at equal intervals in the circumferential direction, and braids 3 made of polyester thread are embedded therein to provide pressure resistance.

The left and right sides of the rope body A are sealed by heat welding or the like to form an air chamber a,
An air plug 4 is provided on the peripheral wall of the air chamber a, and joints 5 are formed at predetermined width intervals along the longitudinal direction.

The joint part 5 is a part whose outer diameter is reduced by pinching and crimping the peripheral wall of the rope main body A, and a small-diameter air passage 6 is secured in the center of the joint part 5, and the joint part 5 is divided from each other. Small air chambers are connected to each other.

In addition, a connecting ring 7 is provided with a string hole 7' formed in a flat portion of the rope body A outside the air chamber a.
are integrally fixed by heat welding, and end treatment is applied to the left and right ends by heat welding, etc., to prevent separation of the side ends of the rope body A. .

Furthermore, the outer circumferential surface of the rope body A is coated with luminous paint to make its presence obvious by emitting light at night, and by making the outer circumferential surface black, it improves weather resistance and prevents cracks. It is possible to prevent this from occurring.

Figures 6 and 7 show the installation state of a seaweed cultivation net using the rope according to the present invention, and the rope body A
to create the desired buoyancy by injecting air into the
The rope is tied to a connecting ring 7 of a rope body A using a rope 8 to a stake 11 driven into the sea, and the rope is stretched in a straight line in parallel. Then, the net 9 is stretched horizontally across the parallel float ropes by strings 10 tied to the joints 5 of the rope body A, and is floated on the sea surface. Since joints are formed on the rope at predetermined intervals, the rope is highly flexible and can prevent damage to the net 9 caused by undulation even when waves arise. At the end of the cultivation period, the air is removed from the rope so that it becomes flat and can be rolled up compactly for easy storage.

In addition, the float rope of the present invention can be used not only for fishing as described above, but also as a course rope for competitive swimming pools, and is made by fitting a large number of float bodies made of styrofoam or the like onto a conventional rope made of hemp or synthetic fibers. Compared to structures, it is easier to handle when installing and removing.

The air plug 4 provided on the peripheral wall of the air chamber a in the rope body A is not limited to one location on one side, but may be provided on both sides of the air chamber a.

(Effects of the Invention) Since the float rope of the present invention is configured as detailed above, the rope and buoyancy are integrated by injecting air into the air chamber. By adjusting the amount of air injected, the buoyancy can be freely adjusted, and the floating state can be easily adjusted. Furthermore, when the air in the air chamber is removed, the rope body becomes flat and can be wound in a spiral to neatly organize the rope, making it easy to store and store.

Furthermore, since the rope body is made of synthetic resin and reinforcing materials, it is extremely lightweight and easy to handle compared to conventional ropes made of hemp or synthetic fibers, and it does not rot, making it durable enough for long-term use. Because the reinforcing material (warp threads) is embedded along the length of the rope, it is strong against tension in the longitudinal direction and can withstand use under tension.

In addition, the rope body is provided with joints at predetermined width intervals along the length, which ensures the flexibility of the rope and prevents the strings, etc. tied to the joints from moving to the left or right. and held in place.

Furthermore, if luminous paint is applied to the outer surface of the rope, it will emit light at night to clearly indicate its presence.
When used as a rope for stringing seaweed aquaculture nets, it can notify ships of the presence of aquaculture nets and call attention to ship operations.
