Yes.

図１、図２の岸壁５の上部にはリアルタイム地震情報を受信する地震早期監視装置１９が設けてあり、該地震早期監視装置１９は地震時に前記解除駆動装置１６に指令信号２０を発することにより、フランジ部１１ａ，１１ｂに嵌合して分離端９ａと固定端９ｂを連結している連結ブロック１３，１４を、フランジ部１１ａ，１１ｂから離反させて連結を解除するようになっている。前記地震早期監視装置１９は浮体構造物１上に設けるようにしてもよく、又、ドルフィン３上に設けてもよい。   1 and 2 is provided with an early earthquake monitoring device 19 for receiving real-time earthquake information. The early earthquake monitoring device 19 issues a command signal 20 to the release drive device 16 during an earthquake. The connection blocks 13 and 14 that are fitted to the flange portions 11a and 11b and connect the separation end 9a and the fixed end 9b are separated from the flange portions 11a and 11b to release the connection. The early earthquake monitoring device 19 may be provided on the floating structure 1 or may be provided on the dolphin 3.

次に、上記実施例の作動を説明する。   Next, the operation of the above embodiment will be described.

図１、図２に示すように、浮体構造物１はドルフィン３（固定構造物）を備えた固定支持装置２と、係留索６からなる緩支持装置７によって支持されており、通常時は、前記浮体構造物１と固定支持装置２との間に備えた拘束装置４によって、浮体構造物１は移動を拘束された状態に支持されている。このとき、図５に示す解除駆動装置１６のシリンダ１５は伸長されて、連結ブロック１３，１４がフランジ部１１ａ，１１ｂに嵌合した状態を保持しているので、前記拘束部材１０は固定具９によって堅固にドルフィン３に固定されている。   As shown in FIGS. 1 and 2, the floating structure 1 is supported by a fixed support device 2 including a dolphin 3 (fixed structure) and a loose support device 7 including a mooring line 6. The floating structure 1 is supported in a state in which movement is restricted by a restraining device 4 provided between the floating structure 1 and the fixed support device 2. At this time, the cylinder 15 of the release drive device 16 shown in FIG. 5 is extended and the connecting blocks 13 and 14 are kept in a state of being fitted to the flange portions 11a and 11b. Is firmly fixed to the dolphin 3.

前記拘束装置４の拘束部材１０と被拘束部材８の係合によって、浮体構造物１は前後左右には僅かな移動で精度良く固定支持装置２に固定され、又、潮位の変化による上下にはスライド自在となっている。従って、浮体構造物１は海上等の任意の場所に安定して保持される。   Due to the engagement of the restraining member 10 of the restraining device 4 and the restrained member 8, the floating structure 1 is fixed to the fixed support device 2 with a small amount of movement back and forth and left and right with high precision. It is slidable. Therefore, the floating structure 1 is stably held at an arbitrary place such as at sea.

一方、地震時には、リアルタイム地震情報を受信している地震早期監視装置１９が地震の大きさを判断し、設定強度以上の地震が発生した際には、該地震早期監視装置１９は前記解除駆動装置１６に指令信号２０を発し、図４、図５に示すようにフランジ部１１ａ，１１ｂに嵌合していた連結ブロック１３，１４を、図６、図７に示すようにフランジ部１１ａ，１１ｂから離反させて固定具９の分離端９ａと固定端９ｂの連結を解除する。   On the other hand, when an earthquake occurs, the early earthquake monitoring device 19 that receives real-time earthquake information determines the magnitude of the earthquake, and when an earthquake of a set strength or higher occurs, the early earthquake monitoring device 19 detects the release drive device. 16 and the connecting blocks 13 and 14 fitted to the flange portions 11a and 11b as shown in FIGS. 4 and 5 are connected to the flange portions 11a and 11b as shown in FIGS. The connection between the separation end 9a and the fixed end 9b of the fixing tool 9 is released by separating.

分離端９ａが切離されると、図６、図８に示すように拘束部材１０は支持を失うので、分離端９ａはドルフィン３から抜き出され、拘束部材１０は重力によって海底に落下する。   When the separating end 9a is separated, the restraining member 10 loses its support as shown in FIGS. 6 and 8, so that the separating end 9a is pulled out from the dolphin 3, and the restraining member 10 falls to the seabed by gravity.

拘束部材１０が落下すると、前記浮体構造物１の被拘束部材８とドルフィン３との間には間隔Ｈが形成され、浮体構造物１は上下、前後左右に自由に移動できるようになる。このとき、地震によって浮体構造物１が前後左右に移動する最大量を予め想定しておき、その最大移動量よりも大きくなるように前記間隔Ｈを設定しておくことにより、地震時に、前記浮体構造物１の被拘束部材８とドルフィン３が衝突して破損する問題は防止される。   When the restraining member 10 falls, a gap H is formed between the restrained member 8 of the floating structure 1 and the dolphin 3, so that the floating structure 1 can freely move up and down, front and rear, and right and left. At this time, it is assumed in advance that the maximum amount that the floating structure 1 moves forward, backward, left, and right due to the earthquake, and the interval H is set to be larger than the maximum movement amount, so that the The problem that the restrained member 8 of the structure 1 and the dolphin 3 collide with each other and are damaged is prevented.

上記したように拘束部材１０が落下すると、浮体構造物１は固定支持装置２による拘束からは解除されることになるが、浮体構造物１は係留索６からなる緩支持装置７によって係留されているので、浮体構造物１は漂流することなく所定の場所に係留される。   When the restraining member 10 falls as described above, the floating structure 1 is released from the restraint by the fixed support device 2, but the floating structure 1 is moored by the loose support device 7 including the mooring line 6. Therefore, the floating structure 1 is moored at a predetermined place without drifting.

図９、図１０は、上記実施例における浮体構造物１とドルフィン３（固定構造物）の間に備える拘束装置４の他の例を示したものであり、図９、図１０では、浮体構造物１には、上下にスライド可能なスライドブロック２１と、該スライドブロック２１に対して水平方向外側に張り出すように上下に固定した支持板２２ａ，２２ｂとからなる被拘束部材２３を設けており、又、ドルフィン３には、水平方向外側に張出して前記支持板２２ａ，２２ｂを上下から挟むように上下に固定した固定支持板２４ａ，２４ｂからなる拘束部材２５を設けており、前記支持板２２ｂは固定支持板２４ｂ上に載置されている。   9 and 10 show another example of the restraining device 4 provided between the floating structure 1 and the dolphin 3 (fixed structure) in the above embodiment. In FIGS. 9 and 10, the floating structure is shown. The object 1 is provided with a constrained member 23 comprising a slide block 21 that can slide up and down and support plates 22a and 22b that are fixed up and down so as to protrude outward in the horizontal direction with respect to the slide block 21. Further, the dolphin 3 is provided with a restraining member 25 composed of fixed support plates 24a and 24b which are extended in the horizontal direction and fixed up and down so as to sandwich the support plates 22a and 22b from above and below. Is placed on the fixed support plate 24b.

更に、前記支持板２２ａ，２２ｂと固定支持板２４ａ，２４ｂを上下に貫通するように形成した貫通孔２６には連結ロッド２７が配置されており、該連結ロッド２７の長手方向中間部の周面には前記被拘束部材２３の上下の支持板２２ａ，２２ｂの間に嵌合する長さの突条２８が形成されている。又、該突条２８の上部には、図１１に示すように、突条２８を切り欠いて前記支持板２２ａと固定支持板２４ａが嵌合できる空間２９が形成されてその空間２９の上部には突部３０が形成されている。更に、前記支持板２２ａ，２２ｂと固定支持板２４ａ，２４ｂの貫通孔２６には、前記突条２８及び突部３０が通過できる溝部３１が形成されている。従って、前記突条２８を溝部３１に一致させると、連結ロッドを支持板２２ａ，２２ｂと固定支持板２４ａ，２４ｂの貫通孔２６に挿通させることができ、更に、前記支持板２２ａと固定支持板２４ａに空間２９が一致した状態では連結ロッド２７を回転させることができるので、連結ロッド２７を回転させて、突条２８及び突部３０と溝部３１の位置をずらすと、突部３０が固定支持板２４ａ上に係止されて連結ロッド２７は支持されるようになっている。尚、下部の支持板２２ｂと固定支持板２４ｂに設けている溝部３１は、破線で示すように上部の支持板２２ａと固定支持板２４ａに設けている溝部３１に対して幅を大きく形成している。   Further, a connecting rod 27 is disposed in a through-hole 26 formed so as to vertically penetrate the support plates 22a and 22b and the fixed support plates 24a and 24b, and the circumferential surface of the intermediate portion in the longitudinal direction of the connecting rod 27 A protrusion 28 having a length that fits between the upper and lower support plates 22a and 22b of the restrained member 23 is formed. Further, as shown in FIG. 11, a space 29 is formed in the upper portion of the protrusion 28 so that the support plate 22 a and the fixed support plate 24 a can be fitted to each other. A protrusion 30 is formed. Further, a groove portion 31 through which the protrusion 28 and the protrusion 30 can pass is formed in the through holes 26 of the support plates 22a and 22b and the fixed support plates 24a and 24b. Accordingly, when the protrusions 28 are aligned with the groove portions 31, the connecting rods can be inserted into the support plates 22a and 22b and the through holes 26 of the fixed support plates 24a and 24b, and the support plate 22a and the fixed support plate. Since the connecting rod 27 can be rotated when the space 29 coincides with the space 24a, the protruding rod 30 is fixedly supported by rotating the connecting rod 27 and shifting the positions of the protrusion 28, the protrusion 30, and the groove 31. The connecting rod 27 is supported on the plate 24a. The groove 31 provided in the lower support plate 22b and the fixed support plate 24b is formed to have a larger width than the groove 31 provided in the upper support plate 22a and the fixed support plate 24a, as indicated by a broken line. Yes.

前記ドルフィン３には、前記突条２８及び突部３０と嵌合する平面コの字形の係合金具３２を有して連結ロッド２７を水平回転させることにより、突部３０が溝部３１からずれた位置と、突部３０が溝部３１と一致した位置とに移動させるようにしたシリンダ３３等の解除駆動装置３４を設けている。   The dolphin 3 has a planar U-shaped engagement fitting 32 that fits the protrusion 28 and the protrusion 30, and the protrusion 30 is displaced from the groove 31 by horizontally rotating the connecting rod 27. There is provided a release drive device 34 such as a cylinder 33 which is moved to a position and a position where the protrusion 30 coincides with the groove 31.

図９、図１０では、通常時は、解除駆動装置３４のシリンダ３３が縮小しており、このとき、支持板２２ａ，２２ｂと固定支持板２４ａ，２４ｂの貫通孔２６に貫通した連結ロッド２７の突部３０及び突条２８は溝部３１からずれた位置に保持されている。従って、被拘束部材２３と拘束部材２５は連結ロッド２７により連結されるので浮体構造物１は拘束装置４によって拘束される。   9 and 10, the cylinder 33 of the release drive device 34 is normally reduced, and at this time, the connecting rod 27 penetrating through the through holes 26 of the support plates 22a and 22b and the fixed support plates 24a and 24b. The protrusion 30 and the protrusion 28 are held at positions shifted from the groove 31. Therefore, since the restrained member 23 and the restraining member 25 are connected by the connecting rod 27, the floating body structure 1 is restrained by the restraining device 4.

一方、地震時には、地震早期監視装置１９は前記解除駆動装置３４に指令信号２０を発して、図１１、図１２に示すように、シリンダ３３を伸長させる。すると、突部３０及び突条２８の位置が溝部３１に一致され、これにより連結ロッド２７は重力により海底に落下する。   On the other hand, during an earthquake, the early earthquake monitoring device 19 issues a command signal 20 to the release drive device 34 to extend the cylinder 33 as shown in FIGS. Then, the positions of the protrusions 30 and the protrusions 28 coincide with the grooves 31, whereby the connecting rod 27 falls to the seabed due to gravity.

連結ロッド２７が落下すると、被拘束部材２３と拘束部材２５との連結は解除され、前記浮体構造物１の被拘束部材２３とドルフィン３との間、及びドルフィン３の拘束部材２５と浮体構造物１との間には間隔Ｈが形成され、浮体構造物１は上下、前後左右に自由に移動することができる。従って、地震によって浮体構造物１が前後左右方向に移動しても、前記浮体構造物１と固定支持板２４ａ，２４ｂ、ドルフィン３と支持板２２ａ，２２ｂが衝突して破損する問題は防止される。又、このとき、浮体構造物１が係留索６からなる緩支持装置７によって係留されることは前記と同様である。   When the connecting rod 27 is dropped, the connection between the restrained member 23 and the restraining member 25 is released, and between the restrained member 23 of the floating structure 1 and the dolphin 3 and between the restraining member 25 of the dolphin 3 and the floating structure. An interval H is formed between the floating structure 1 and the floating structure 1 so that the floating structure 1 can freely move up and down, front and rear, and right and left. Therefore, even if the floating structure 1 moves in the front-rear and left-right directions due to an earthquake, the problem that the floating structure 1 and the fixed support plates 24a and 24b collide with each other and the dolphin 3 and the support plates 22a and 22b are damaged is prevented. . At this time, the floating structure 1 is moored by the loose support device 7 including the mooring line 6 as described above.

図１３、図１４は、本発明の他の実施例を示すもので、図１３、図１４では、海底地盤に固定するようにしたスパット３５（固定構造物）を有する固定支持装置２を設けた場合を示しており、前記スパット３５から浮体構造物１を貫通するように鉛直に設けられた支持ロッド３６と浮体構造物１との間に拘束装置４を設けている。前記浮体構造物１は２ヶ所に設けたスパット３５からなる固定支持装置２によって支持されており、更に、浮体構造物１は四方に設けた係留索６による緩支持装置７によって係留されている。   FIGS. 13 and 14 show another embodiment of the present invention. In FIGS. 13 and 14, a fixed support device 2 having a spat 35 (fixed structure) fixed to the seabed ground is provided. The restraint device 4 is provided between the support rod 36 and the floating structure 1 that are vertically provided so as to penetrate the floating structure 1 from the spat 35. The floating structure 1 is supported by a fixed support device 2 composed of a spat 35 provided at two locations, and the floating structure 1 is moored by a loose support device 7 by mooring lines 6 provided at four sides.

前記拘束装置４は、前記支持ロッド３６に昇降可能に嵌合した矩形ブロック形状の拘束部材３７と、該拘束部材３７と前後左右には設定間隔で移動でき上下にはスライドできるように浮体構造物１に固定したフェンダ等からなる被拘束部材３８を有している。   The restraining device 4 includes a rectangular block-shaped restraining member 37 fitted to the support rod 36 so as to be movable up and down, and a floating structure so that the restraining member 37 can move up and down and right and left at a set interval and can slide up and down. 1 has a restrained member 38 made of a fender or the like fixed to 1.

更に、前記拘束部材３７の上端には、図１５、図１６、図１７に示すように、支持ロッド３６の上端を閉塞する閉塞部材３９が配置されており、閉塞部材３９は横方向一方向への移動のみを許す係止具４０によって支持されている。更に、前記閉塞部材３９の上部には鉛直なロッド４１が固定されていると共に、該ロッド４１に対して昇降可能に嵌合した嵌合管４２が設けてあり、該嵌合管４２は、浮体構造物１に設けたシリンダ４３等からなる解除駆動装置４４の伸縮ロッド４３ａに固定されており、前記シリンダ４３を伸縮すると、閉塞部材３９を移動させて前記支持ロッド３６の上端を閉塞した状態と解放した状態とに切換えられるようになっている。   Further, as shown in FIGS. 15, 16, and 17, a closing member 39 that closes the upper end of the support rod 36 is disposed at the upper end of the restraining member 37, and the closing member 39 extends in one lateral direction. It is supported by the locking tool 40 which permits only the movement. Further, a vertical rod 41 is fixed to the upper portion of the closing member 39, and a fitting tube 42 fitted to the rod 41 so as to be movable up and down is provided. The fitting tube 42 is a floating body. It is fixed to an expansion / contraction rod 43a of a release drive device 44 comprising a cylinder 43 or the like provided in the structure 1, and when the cylinder 43 is expanded / contracted, the closing member 39 is moved to close the upper end of the support rod 36. It can be switched to the released state.

図１３〜図１７の実施例では、通常時は、解除駆動装置４４のシリンダ４３は伸長されて、閉塞部材３９が支持ロッド３６の上端を閉塞しており、よって、拘束部材３７は閉塞部材３９によって支持ロッド３６の上端に支持されている。このとき、浮体構造物１が波浪により昇降するとロッド４１も昇降するが、ロッド４１に昇降可能に嵌合した嵌合管４２によって閉塞部材３９の位置が位置決めされているので閉塞部材３９が移動することはない。従って、上記支持ロッド３６に支持された拘束部材３７と該拘束部材３７を取り巻くように浮体構造物１に備えられた被拘束部材３８からなる拘束装置４によって、浮体構造物１は前後左右方向の移動が拘束される。   In the embodiment shown in FIGS. 13 to 17, the cylinder 43 of the release drive device 44 is normally extended, and the closing member 39 closes the upper end of the support rod 36, so that the restraining member 37 is closed. Is supported by the upper end of the support rod 36. At this time, when the floating structure 1 is moved up and down by waves, the rod 41 is also moved up and down. However, the position of the closing member 39 is positioned by the fitting tube 42 fitted to the rod 41 so as to be able to move up and down, so that the closing member 39 moves. There is nothing. Therefore, the floating structure 1 is moved in the front-rear and left-right directions by the restraining device 4 including the restraining member 37 supported by the support rod 36 and the restrained member 38 provided in the floating structure 1 so as to surround the restraining member 37. Movement is restrained.

一方、地震時には、地震早期監視装置１９は前記解除駆動装置４４に指令信号２０を発して、図１８に示すようにシリンダ４３を縮小させる。すると、支持ロッド３６の上端を閉塞していた閉塞部材３９が移動されて支持ロッド３６の上端を開放するので、支持ロッド３６に支持されていた拘束部材３７は支持を失って重力により下方に落下する。   On the other hand, during an earthquake, the early earthquake monitoring device 19 issues a command signal 20 to the release drive device 44 to reduce the cylinder 43 as shown in FIG. Then, the closing member 39 that has closed the upper end of the support rod 36 is moved to open the upper end of the support rod 36, so that the restraining member 37 supported by the support rod 36 loses support and falls downward due to gravity. To do.

拘束部材３７が落下すると、拘束部材３７と支持ロッド３６との間には間隔Ｈが形成され、浮体構造物１は上下、前後左右に自由に移動することができるようになる。従って、地震によって浮体構造物１が前後左右方向に移動しても、支持ロッド３６と被拘束部材３８が衝突して破損する問題は防止される。又、このとき、浮体構造物１が係留索６からなる緩支持装置７によって係留されることは前記と同様である。   When the restraining member 37 falls, a gap H is formed between the restraining member 37 and the support rod 36, and the floating structure 1 can freely move up and down, front and rear, and right and left. Therefore, even if the floating structure 1 moves in the front-rear and left-right directions due to an earthquake, the problem that the support rod 36 and the restrained member 38 collide and are damaged is prevented. At this time, the floating structure 1 is moored by the loose support device 7 including the mooring line 6 as described above.

尚、本発明の係留方法及び装置は、上述の実施例にのみ限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。   The mooring method and apparatus of the present invention are not limited to the above-described embodiments, and various changes can be made without departing from the scope of the present invention.
