Description

[0001] Mooring system has safety rope [0002]

The present invention relates to an elastic mooring apparatus having a safety rope, and more particularly, to an elastic mooring apparatus having a safety rope, and more particularly, to an elastic mooring apparatus having a safety rope, The present invention relates to a resilient mooring device provided with a safety rope having a mooring stability at all times so as to prevent a dead body from being lost when the rope is broken.

In general, a float-type floating structure (hereinafter referred to as "floating body") installed in a sea or a river adopts a mooring method in which a mooring line such as a rope is connected to a fixed structure.

In other words, the body to be installed in the sea or river may be, for example, a yacht harbor, a marine yard, various floating bridges, a breakwater, a water and aquapark, a water house, a water golf course, It can be easily found in a mooring station. Such a mooring member can not be moved left or right or upward or downward due to variation of the water level due to difference of tide water or flood occurring in the sea or river, and in order to stably catch the water, And to the mooring line.

FIG. 1 is a perspective view showing a structure in which a mooring line according to the related art is connected to a body.

As shown in the drawing, a conventional mooring line according to the prior art includes a rope 3 installed between a corner of a body 1 floating on the water surface and a plurality of anchors 2 seated on the sea floor, .

Since the conventional mooring line has a structure in which an anchor 2 seated on the bottom surface and a floating body 1 on the water surface are simply connected to the rope 3 or the like, And when a load such as an excessive tension acts on the mooring line due to the blue and strong winds during the mooring of the main body 1, the mooring line breaks due to a strong impact on the main body 1 and the like An accident or the like may occur.

In recent years, it is possible to prevent the phenomenon that the mooring line which moored the mooring is cut by the external force and at the same time, the external impact which is applied to the mooring body is gradually buffered so as to stably protect the mooring line, A mooring system using a mooring device has been developed and used.

For example, prior art documents such as Korean Patent Registration No. 1001491 and Korean Patent Registration No. 1171441 disclose a technique related to a mooring device.

FIG. 2 is a perspective view showing a state where a subject is moored to a fixing structure of a water floor using a mooring device according to the related art, and FIG. 3 is a plan view of the mooring device according to the related art.

As shown in FIG. 2, a floating body 20 floats on the water surface 10, and fixing structures 30 for mooring the floating body 20 are installed on the floor 12.

One end of the mooring device 40 is connected to each fixed structure 30 and the other end of the mooring device 40 is connected to the supporting body 20 via the rope 50. [ A total of four ropes 50 are provided, one for each corner of the body 20, and the two ropes 50 on the same side are arranged in an X-shape staggered from each other.

When the water level rises in the mooring state as shown in Fig. 2, the body 20 also rises, allowing the body 20 to rise while the mooring device 40 is stretched.

Even when the water level is lowered again, the mooring device 40 is contracted and a force is applied to the body 20 so that the body 20 can stably maintain its position.

2 and 3, the conventional mooring device 40 includes a plurality of elastic strands 42 having a large elasticity, a fixing structure 30 for connecting both ends of the elastic strands 42 together, and a rope 50 And a fastener 44 provided with a ring 44a and a pulley 44b for connecting to the pulleys 44a and 44b, respectively.

The length and the number of strands of the elastic strands 42 are appropriately determined depending on the distance between the fixing structure 30 and the supporting body 20, the degree of fluctuation of the water level, the size and weight of the supporting body 20,

However, in the conventional mooring device 40 shown in Figs. 2 and 3, when the water level fluctuation occurs more than expected, the rubber strip 42 may be broken in the elongated state.

In the conventional mooring device 40, since only one of the strands 42 is damaged, the mooring device 40 must be replaced.

In addition, since the conventional mooring device 40 is exposed to the outside, there is a risk that the rubber strip 42 may be broken even when a sharp object is torn in a state where the rubber strip 42 is stretched.

Accordingly, the conventional mooring device 40 may be connected to the connecting rods 44 of a predetermined length so that the rubber strands 42 do not extend beyond a predetermined length.

In addition, the conventional mooring device 40 must firmly connect the end of the rubber strip 42 and the connector 44 so that the rubber strip 42 does not get out of the connector 44 even when the rubber strip 42 is stretched to the maximum. It was difficult and time-consuming.
