できる。 Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mooring device using a mooring chain for a floating body such as a floating breakwater, a floating pier, a floating platform, etc., and more particularly to a mooring chain in a shallow water area. A suitable mooring device. 2. Description of the Related Art As a conventional means for mooring a floating body, FIG.
As shown in (a), both ends of the floating body 1 are formed in a U-shape,
A dolphin-type mooring device in which each end of the U-shape is fitted via a fender 3 to dolphins 2 and 2 fixedly provided at a fixed position on the sea, or a floating body 1 as shown in FIG. A hose pipe 4 for pulling in the mooring chain is arranged at one end, and one end of the mooring chain 5 is connected to the deck of the floating body 1,
An anchor chain type mooring device and the like having the other end connected to an anchor 6 provided on the seabed through the hose pipe 4 are known. [0003] The dolphin-type mooring device shown in FIG. 6A is suitable for shallow water, but the production and construction of the dolphin 2 is expensive, and the overall cost is large. There is a problem that it becomes high. For this reason, in general, an anchor chain type mooring device shown in FIG. 6B is often used. However, in this mooring method, when the floating body 1 is moored in a shallow place having a water depth of, for example, 10 m or less, the mooring chain 5 is mainly used. There is a possibility that excessive stress may be generated in the chain 5 and the chain connecting portion of the floating body 1 due to insufficient swing amount due to insufficient loosening of the body. FIG. 7 shows a comparison between the horizontal displacement of the floating body and the force acting on the chain at the time of large water depth and at the time of shallow water depth in the anchor chain type mooring device. The mooring chain 5 is stretched in a catenary curve under an initial load (chain's own weight), and the slack of the chain 5 is large at a large water depth and small at a shallow water depth. Thus, large horizontal swing amount d 1 of the floating body 1 up to the point showing the maximum load design from the point indicating the static load chain mooring force in deepwater 7, whereby even when oceanographic condition is poor The floating body 1 can be stably moored. On the other hand, at shallow water depth, the horizontal swing amount d 2 of the floating body 1 from when the chain mooring force rises to the design maximum load after the static mooring force is smaller than at the deep water depth.
For this reason, a slight movement of the floating body 1 causes a large tension to be generated in the chain 5, which may eventually lead to an accident such as breakage of the chain. Accordingly, the present invention improves the mounting structure of a chain to a floating body while adopting an inexpensive anchor chain type mooring system, and applies excessive tension or impact to a chain or a chain connecting portion even in a shallow water area. Then, as it is not to apply
In addition, it is an object of the present invention to provide a floating body mooring device capable of preventing damage and wear of a chain . In order to solve the above-mentioned problems, a floating body mooring device according to the present invention has one end of a mooring chain connected to a seabed anchor, and the other end of the chain connected to a floating body .
In a mooring device connected to a telescopic end of an elastic mechanism installed in a recess so as to be capable of changing a stroke, a main body of the elastic mechanism is rotatable from a water surface in a vertical plane including a mooring locus of the mooring chain. Also mounted on the floating body above
And the outer wall of the main body of the elastic mechanism and the inner wall of the recess
And a restoring means is inserted between them. In the floating body mooring device of the present invention described above, when the floating body receiving the external force moves largely horizontally and the tension of the slack chain stretched at shallow depth increases, the chain tension is applied to the floating body. The connected elastic mechanism contracts, and this contraction stroke is added to the slack amount of the chain, thereby increasing the allowable swing amount of the floating body and relaxing the chain tension. The attached elastic mechanism rotates appropriately in the vertical plane including the mooring locus of the chain in accordance with the chain tension, whereby the compression stroke of the elastic mechanism is more smoothly added to the amount of slack in the chain, and The tension gradually increases or decreases. The rotation of the elastic mechanism is upward.
It is performed smoothly by the restoring action of the restoring means,
The chain may be damaged by contact with the outlet of the recess.
Wear is prevented. An embodiment of the present invention will now be described with reference to FIGS.
This will be described with reference to FIG. FIG. 1 schematically shows the state of mooring of a floating body by the mooring device of the present invention. The floating body 1 is provided between an anchor 6 provided on the sea floor and an elastic mechanism 7 inside a recess 8 formed on the floating body 1. It is moored by the mooring chain 5 which is stretched. The main body of the elastic mechanism 7 (see reference numerals 14 and 18 in FIG. 4) is attached to the floating body 1 above the water surface as shown in FIG. The elastic mechanism 7 is extendable and contractable by a predetermined stroke in the direction in which the mooring chain 5 is pulled in, and the mooring chain 5 is connected to the telescopic end of the elastic mechanism 7. Is attached to the floating body 1 so as to be freely rotatable in a vertical plane direction including the following. FIG. 2 shows a main part of the mooring device according to the first embodiment of the present invention. The main body of the elastic mechanism 7 has its upper part fixed to the floating body 1 above the water surface as described above. The connecting member 9 and the pin 10 are connected by a pin 10 and are rotatable in a predetermined range around the center of the pin. The connecting member 9 is installed in a recess 8 formed in the floating body 1. A restoring means 11 such as a coil spring is inserted between an outer wall of the main body of the elastic mechanism 7 and an inner wall of the recess 8 as an auxiliary means for smoothly performing the rotation operation. The recess 8 is formed so as to have a space that does not hinder the turning operation of the main body of the elastic mechanism 7 and the pulling-in operation of the mooring chain 5 at that time. FIGS. 3A and 3B show a main part of a mooring device according to a second embodiment of the present invention. In this embodiment, the elastic mechanism 7 is used.
A pair of connecting members 13 is attached to the upper part of the outer wall of the main body, and is connected to the inner wall of the recess 8 formed on the floating body 1 by the pins 12 so as to be rotatable within a predetermined range around the center of the pins. As in the embodiment, a restoring means 11 is inserted between the outer wall of the main body of the elastic mechanism 7 and the inner wall of the recess 8. FIGS. 4A and 4B show examples of the structure of the elastic mechanism 7 in the first and second embodiments. FIG. 4A shows an example in which a coil spring is used as the expansion and contraction means. The ends of the coil spring 15 housed in the case 14 are
Fixed plate 17 fixed to case 14 as the main body of elastic mechanism 7
And a movable plate 16 movable along the inner wall of the case 14, the mooring chain 5 is passed through the coil spring 15, and its end is connected to the movable plate 16. FIG. 4B shows an example in which a cell type fender is used. A fixing plate 21 in which both ends of a fender 19 housed in a case 18 as a main body of the elastic mechanism 7 are fixed to the case 18 and a case 18 The chain 5 is sandwiched by a movable plate 20 movable along the inner wall, the chain 5 is passed through the fender 19, and its end is connected to the movable plate 20. Hereinafter, the operation of the mooring device according to the first and second embodiments will be described. The floating body 1 is usually moored by a plurality of mooring devices (see FIGS. 1 to 6).
When the floating body 1 is largely moved in the horizontal direction by receiving an external force such as wind and waves, the mooring chain 5 is pulled, and the elastic mechanism 7 attached to the floating body 1 is contracted by the chain tension generated at that time, so that the chain 5 By adding the contraction stroke amount to the slack amount of the floating body 1, the large horizontal movement amount of the floating body 1 is absorbed, and the chain tension is reduced. At this time, the elastic mechanism 7 rotatably mounted in the recess 8 moves around the pin 10 in the first embodiment of FIG. In the second embodiment, the pin 12 is appropriately rotated in the pull-in direction of the chain 5, that is, in the vertical plane including the chain mooring locus, whereby the compression stroke of the elastic mechanism 7 is smoothly performed. Chain tension increases or decreases slowly,
Excessive tension or impact is not applied to the chain 5 or the chain connection portion. Further, the rotation of the elastic mechanism 7 is smoothly performed by the restoring action of the restoring means 11 attached to both side walls of the elastic mechanism 7, and the chain 5 comes into contact with the outlet of the recess 8 to be damaged or worn. Accidents such as dripping are prevented. FIG. 5 shows the mooring characteristics of the mooring device according to the present invention. The horizontal displacement of the floating body 1, that is, the allowable swing amount, while the chain mooring force increases from the static load (steady load) to the design maximum load. It can be seen that d is greatly increased by the addition of the contraction stroke of the elastic mechanism 7. In the characteristic curves in FIG. 5, the dotted line indicates the case where the elastic mechanism 7 is not provided with a rotation function, and the solid line indicates the case where the same mechanism is provided with a rotation function. It can be seen that the chain tension changes gradually due to this. As described above in detail, in the floating mooring device of the present invention, the mooring chain is provided with the straw in the recess of the floating body.
The floating body is connected to the floating body above the water surface via an elastic mechanism installed so as to be movable, and the elastic mechanism is configured to be rotatable in the vertical plane direction including the mooring trajectory of the mooring chain. When the chain tension increases due to large horizontal movement, the elastic mechanism contracts and the contraction stroke is added to the slack amount of the chain, thereby increasing the allowable swing amount of the floating body and reducing the chain tension It is made to so that. At this time, since the elastic mechanism rotates appropriately in response to the chain tension, the contraction stroke operation of the elastic mechanism is performed more smoothly, and the chain tension gradually increases and decreases. There is an effect that tension or impact is not applied and damage to the main part of the device is prevented. In addition, the outer wall of the main body of the elastic mechanism and the inner wall of the recess are provided.
The restoring means is inserted between the
The moving operation is performed smoothly by the restoring means.
So that the chain is at the outlet of the recess
To prevent damage or wear in contact with
it can.
