Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multiple winding device for a cable with a fairing used in a towing body or the like.

In recent years, in order to efficiently observe the state of ocean pollution, investigate tidal currents, salinity, and other physical properties of seawater, as shown in Figure 1, a cable 2 is towed from a towing vessel 1, and a cable 2 is attached to the tip of the cable for observation purposes. A system has been developed in which a towing body 3 loaded with measuring instruments corresponding to the above is attached, and measured values are transmitted to the towing vessel 1 from time to time. However, since the cable 2 has a circular cross-sectional shape, it has a large resistance coefficient and requires a long length to reach the seabed. A number of fins called fairings 4 having an airfoil-shaped cross section as shown in FIG. 2 are rotatably attached to the tow line 2.

Such a cable 2 is connected to the towing vessel 1 when the towing body is inconvenient.
The fairing 4 is wound around the outer periphery of the cylinder of the winder and pulled up together with the towing body onto the towing vessel 1.
It is generally weaker than towline 2, and it deforms and loses the effect of reducing the drag coefficient of the towline the next time it is used. I can't.

Therefore, in general, it has to be wound in a single layer on a cylinder, and as a result, there is a problem that the diameter of the cylinder becomes large and the length in the axial direction becomes long.

The present invention is an attempt to solve these problems. A large number of cylinders are provided in the same D-circle shape, each cylinder is structured so that they can freely rotate with respect to each other, and a cable is installed on the circumferential surface of each cylinder. A long slit in the axial direction is provided to allow the material to pass freely.
By fixing one end of the cable to the innermost cylinder and connecting the other end to the towing body through the slit in each cylinder,
When winding the cable, the innermost cylinder is first wound in a single layer, then the second inner cylinder is fixed together with the first cylinder and rotated together to wind the cable.
To provide a multiple cable winding device which winds up a cable while fixing an outer cylinder one after another.

For this reason, the cable multiple winding device of the present invention has a plurality of cylinders spaced apart from each other in the same D circle around the drive shaft, and arranged so as to be rotatable independently of the drive shaft. The cylinder is provided with a slit in the axial direction, and a means for locking the cylinder to the drive shaft sequentially from the drive shaft side, and one end of the cable passing through the slit of each cylinder is connected to the drive shaft. Or, it is characterized by being fixed to a cylinder closer to the same grade.

Hereinafter, embodiments of the present invention will be explained with reference to the drawings.
FIG. 4 is a side view of an embodiment of the cable multiplex winding device of the present invention, FIG. 5 is a front view, and FIG. 6 is a cross-sectional view of a cylinder.

In these figures, 10 has both ends supported by supports 11a, 11
Drive shafts 12a, 12b, 12c, and 12d are supported by bearings etc. on b and are connected to an outer motor (not shown) so as to rotate in any direction. Cylinders 13 are arranged at intervals from each other and are rotatable with respect to each other so that a sufficient clearance is maintained when the cable 2 is wound around the drive shaft 1.
0 in the diametrical direction, and each cylinder 12a, 12b
, 12c, 12d, each of the cylinders 12 has a stopper that can be inserted into the receiving hole 14, respectively.
The slits are long and closed in the axial direction on the circumferential surfaces of the cables a, 12b, 12c, and 12d, allowing the cable 2 to freely pass through them.

For ease of explanation, FIG. 7 shows the cylinder 12a in FIG.
Although it is a perspective view with only 12b taken out, by this,
To explain the operation of the cable multiple winding device of the present invention, first, the stopper 13 that fixed the inner cylinder 12a and the outer cylinder 12b is removed from the receiving hole 14 of the outer cylinder 12b, and the outer cylinder 12b is made to stand still. When only the inner cylinder 12a is rotated, the cable 2 passes through the slit 15 of the outer cylinder 12b and is wound around the inner cylinder 12a.

After winding the cable 2 in a line around the inner cylinder 12a, insert the stopper 13 into the receiving hole 14 of the outer cylinder 12b,
The inner and outer cylinders 12a and 12b are fixed.

When the drive shaft 10 is rotated again, the cable 2 is wound around the outer cylinder 12b.

In this way, the cable 2 is wound around the cylinders 12c and 12d one after another. In the case of unwinding the cable 2, the above winding operation may be performed in reverse. The cable multiplex winding device of the present invention is capable of compactly winding special cables that cannot be multiplexed in this way, thereby saving space on the deck of a towing ship. This has the advantage of preventing damage to the cable itself or damage or deformation of the cable fairing due to multiple winding of the conventional multiple winding device.

The cable multiple winding device of the present invention can be used not only for winding cables that cannot be directly overlapped as shown in the embodiments, but also for winding main lines in longline fishing, or buckets for collecting manganese nodules, a seabed mineral resource. can also be applied.

In the above embodiment, the cable is first wound around the innermost cylinder, but it goes without saying that if the diameter of the drive shaft 10 is increased, the cable 2 can also be wound directly around the drive shaft 10. There is no such thing.
