Description

異常時の増水を自動的に防御し、増水の被害を軽減するものである。  It automatically protects against water increase during anomalies and reduces damage from water increase.

異常時の増水に対しては電力又は人力により水門を閉じる方法が主流であるが、これを常時維持管理を行うも、不測の事故、故障の恐れは避けられない、又、設置に対しては多大の建設費を必要とする。  The method of closing the sluice gate by electric power or human power is the mainstream for water increase in the event of an abnormality, but even if this is always maintained and managed, there is an unavoidable risk of unexpected accidents and breakdowns. Significant construction costs are required.

本発明は津波の堤防又は堤防の機能を持つ道路への溢液、津波の河川入口への浸水又は河川上流よりの雨水や洪水等を異常時の増水を利用して自動的に防水を行うものである。  The present invention automatically waterproofs tsunami levee or flooding to roads with dyke function, flooding of tsunami at the river entrance or rainwater or flooding from upstream of the river by using water increase at the time of abnormality It is.

本発明の防水装置は平時両開きの左右の扉５及び６を全開の位置に停止しておき、津波等が押寄せたときは波受室２２内の扉固定装置３４の板状浮体３５が押上げられると、これを取付けている左右の支持棒３６及び３７が支点３８及び３９を中心として傾き、反対側の先端に取付けられている扉停止棒４０及び４１を引下げて扉の拘束を解除する、又保守点検のときこの扉停止棒を足踏等で押下げて扉の拘束を解き作業を行うことが出来る。  In the waterproof device of the present invention, the left and right doors 5 and 6 that are normally open are stopped at the fully open position, and when a tsunami or the like is pushed, the plate-like floating body 35 of the door fixing device 34 in the wave receiving chamber 22 is pushed. When lifted, the left and right support rods 36 and 37 attached thereto are tilted around the fulcrums 38 and 39, and the door stop rods 40 and 41 attached to the opposite ends are lowered to release the restraint of the door. Also, at the time of maintenance inspection, the door stop rod can be pushed down with a foot or the like to release the restraint of the door.

本発明の防水装置の構造は両開きの左右の扉５及び６を取付けた左右の主軸７及び８を、左右の上部軸受１０及び１２と左右の下部軸受１８及び２０によって左右の壁３及び４に沿うて垂直に設置する。  In the structure of the waterproof device of the present invention, left and right main shafts 7 and 8 to which left and right doors 5 and 6 having double doors are attached are attached to left and right walls 3 and 4 by left and right upper bearings 10 and 12 and left and right lower bearings 18 and 20, respectively. Install vertically.

そしてこれの左右の主軸を左右の扉５及び６の設置場所の地下の波受室２２内まで延長して、ここに長尺波受板２４及び２５を各扉と約４５度ずらした位置に固定した後、その各々の先端に左右の短尺波受板２６及び２７を蝶番２８及び２９により連結し、この左右の短尺波受板を中央の蝶番３０で遥動しうるよう連結して一本の波受帯２３を形成し、波受室２２に津波が押寄せた時、この波受帯２３はこれを受けて押流されて左右の主軸７及び８に固定した左右の扉５及び６を左回転又は右回転させる。  The left and right main shafts are extended into the underground wave receiving chamber 22 where the left and right doors 5 and 6 are installed, and the long wave receiving plates 24 and 25 are shifted from the doors by about 45 degrees. After fixing, the left and right short wave receiving plates 26 and 27 are connected to the respective tips by hinges 28 and 29, and the left and right short wave receiving plates are connected so as to be able to swing with a central hinge 30 to provide a single piece. Left and right doors 5 and 6 fixed to the left and right main shafts 7 and 8 when the tsunami is pushed into the wave receiving chamber 22. Rotate left or right.

この時左右の長尺波受板２４及び２５の下辺には左右の底板付扇形歯車３１及び３２が取付けられており、これらが互いに噛合うことにより、左右の主軸７及び８は常に同角速度で反対方向に回転する、従って左右の扉５及び６は左右より同時に閉鎖されるようになる。  At this time, fan gears 31 and 32 with left and right bottom plates are attached to the lower sides of the left and right long wave receiving plates 24 and 25, respectively, so that the left and right main shafts 7 and 8 always have the same angular velocity. It rotates in the opposite direction, so the left and right doors 5 and 6 are closed simultaneously from the left and right.

図３より図６は左扉５の左主軸７の左上部軸受１０を左蔓巻ボールねじ１４の構造にし、開扉時、閉扉時、閉扉時中に左扉をジャッキで突上げた時、及びジャッキで突上げ中、これを開扉した時の作動を示す断面拡大図である。  From FIG. 3 to FIG. 6, the left upper bearing 10 of the left main shaft 7 of the left door 5 has the structure of the left swirl ball screw 14, and when the left door is pushed up with a jack during opening, closing, and closing, FIG. 5 is an enlarged cross-sectional view showing an operation when the door is opened while being pushed up with a jack.

左扉５の左上部軸受１０を緩勾配の左蔓巻ボールねじ１４の構造、右扉６の右上部軸受１２を緩勾配の右蔓巻ボールねじ１５の構造にすることによって重い左右の扉５及び６はその自重によりねじ面に沿うて下降しながら扉の閉じる方向に向かって左回転又は右回転しようとする、この回転力を扉固定装置３４の扉停止棒４０及び４１により押留めておき、津波等が押寄せたとき、波受帯２３はこれを受けて押流されて左右の扉５及び６を閉じようとする時、同時に津波により扉停止棒４０及び４１が引下げられて左右の扉の拘束を解かれるので、上記の回転力が復活して波受帯２３が扉を閉じようとする作動を助勢するようにする。  By making the left upper bearing 10 of the left door 5 a structure of the left vine ball screw 14 with a gentle gradient and the right upper bearing 12 of the right door 6 with a structure of the right vine ball screw 15 of a gentle gradient, the heavy left and right doors 5. And 6 are held down by the door stop rods 40 and 41 of the door fixing device 34 so as to rotate leftward or rightward toward the door closing direction while descending along the screw surface due to their own weight. When the tsunami or the like is pushed in, the wave receiving band 23 is swept away and tries to close the left and right doors 5 and 6, and at the same time, the door stop rods 40 and 41 are pulled down by the tsunami and the left and right doors Since the door is unconstrained, the rotational force is restored and the wave band 23 assists the operation of closing the door.

しかし開扉のときは上記と逆にねじ面に逆のぼる必要があるために容易ではない、従って開扉に先立って、左右の主軸７及び８の底面のセンター孔９を油圧ジャッキ３３等により突上げて左右の蔓巻ボールねじの外輪１６の底に隙間を作った後、左右の主軸７及び８を油圧ジャッキ３３のセンターの上で回転することにより左右の扉５及び６を小さな力で開くことを可能にする。  However, when opening the door, it is not easy because it is necessary to go back to the threaded surface contrary to the above. Therefore, before opening the door, the center holes 9 on the bottom surfaces of the left and right main shafts 7 and 8 are projected by the hydraulic jack 33 or the like. After raising and making a gap in the bottom of the outer ring 16 of the left and right swoop ball screws, the left and right doors 5 and 6 are opened with a small force by rotating the left and right main shafts 7 and 8 on the center of the hydraulic jack 33. Make it possible.

本発明の防水装置により多額の建設費を要する従来の電力による水門よりの転換が可能となって、その管理も容易に行うことが可能になる。  The waterproof device of the present invention enables conversion from a sluice gate using conventional electric power that requires a large amount of construction cost, and can be easily managed.

左右の扉５及び６は左右の主軸７及び８に取付けて両開きするように、そしてこれら左右の主軸を左右の扉５及び６の設置場所の地下の波受室２２内まで延長して、ここに左右の長尺波受板２４及び２５を各扉と約４５度ずらした位置に固定した後、その各々の先端に左右の短尺波受板２６及び２７を蝶番２８及び２９により連結し、この左右の短尺波受板を中央の蝶番３０で遥動しうるよう連結して、一本の波受帯２３を形成し、波受室２２に津波が押寄せた時、この波受帯２３はこれを受けて押流されて左右の主軸７及び８に固定した左右の扉５及び６を左回転又は右回転させる。  The left and right doors 5 and 6 are attached to the left and right main shafts 7 and 8 so as to open both sides, and these left and right main shafts are extended into the underground wave reception chamber 22 at the installation location of the left and right doors 5 and 6. The left and right long wave receiving plates 24 and 25 are fixed at positions shifted by about 45 degrees from the doors, and the left and right short wave receiving plates 26 and 27 are connected to the respective tips by hinges 28 and 29. The left and right short wave receiving plates are connected so as to be able to move with a central hinge 30 to form one wave receiving band 23. When a tsunami is pushed into the wave receiving chamber 22, the wave receiving band 23 is In response to this, the left and right doors 5 and 6 fixed to the left and right main shafts 7 and 8 are swung left or right.

左右の扉の一方が早く閉じ始めると、この扉を押して流れる水は片方の扉の裏に流れ込み、その扉の閉鎖を妨げることになる、この現象を避けるため左右の長尺波受板２４及び２５の下辺には左右の底板付扇形歯車３１及び３２が取付けられており、これらが互に噛合うことにより左右の主軸７及び８は常に同角速度で反対方向に回転する、従って左右の扉５及び６は左右より同時に閉鎖されるようにする。  When one of the left and right doors begins to close quickly, the water that flows through the door flows into the back of one door and prevents the door from closing. To avoid this phenomenon, the left and right long wave receiving plates 24 and Left and right fan-shaped gears 31 and 32 are attached to the lower side of 25, and the left and right main shafts 7 and 8 always rotate in the opposite direction at the same angular speed by engaging with each other. And 6 are closed simultaneously from the left and right.

上記の波受帯２３に押寄せた津波の力により扉を閉じるとき、その扉の主軸を軽く回転しなければならない。このため図１に示したように通常のボール軸受により扉の重量を支える構造に代わって、図３に示すように蔓巻ボールねじ１４及び１５により、扉の重量を受けるようにすると、重い左右の扉５及び６はその自重によりねじ面に沿うて下降しながら扉の閉じる方向に向かって左回転又は右回転しようとする、この回転力を扉固定装置３４の扉停止棒４０及び４１により押留めておき、津波等が押寄せたとき波受帯２３はこれをうけて流されて左右の扉５及び６が閉じようとする時、同時に津波により扉停止棒４０及び４１が引下げられて、左右の扉の拘束を解かれるので上記の回転力が復活して波受帯２３が扉を閉じようとする作動を助勢するようにする。  When the door is closed by the force of the tsunami pressed against the wave band 23, the main shaft of the door must be lightly rotated. Therefore, instead of the structure that supports the weight of the door by a normal ball bearing as shown in FIG. 1, if the weight of the door is received by the vine ball screws 14 and 15 as shown in FIG. The doors 5 and 6 are driven by the door stop rods 40 and 41 of the door fixing device 34 so as to rotate leftward or rightward in the closing direction of the door while descending along the screw surface due to their own weight. Keeping in mind, when the tsunami or the like is pushed, the wave receiving band 23 is swept away by this and when the left and right doors 5 and 6 try to close, the door stop bars 40 and 41 are pulled down simultaneously by the tsunami, Since the left and right doors are unconstrained, the rotational force is restored and the wave receiving band 23 assists the operation of closing the doors.

左右の上部軸受１０及び１２に左右の蔓巻ボールねじ１４及び１５を使用した場合、閉じられた左右の扉５及び６を開けるためには、図５に示すように左右の主軸７及び８の底面のセンター孔９を油圧ジャッキ３３、スクリュージャッキ等により突上げて左右の蔓巻ボールねじの外輪１６の底に隙間を作る。  When the left and right swirl ball screws 14 and 15 are used for the left and right upper bearings 10 and 12, in order to open the closed left and right doors 5 and 6, as shown in FIG. The center hole 9 on the bottom surface is pushed up by a hydraulic jack 33, a screw jack or the like to create a gap in the bottom of the outer ring 16 of the left and right swirl ball screws.

次に図６に示すように左右の扉の主軸７及び８を油圧ジャッキのセンター等の上で回転させる。このとき主軸を回転させても外輪１６は回転せずに次第に降下して底の隙間は埋めるように降下する、従って左右の主軸７及び８は蔓巻ボールねじによる抵抗を受けることなく自由に油圧ジャッキ３３のセンターの上を回転することが出来、従って左右の扉５及び６は小さな力で開くことが可能になる。  Next, as shown in FIG. 6, the main shafts 7 and 8 of the left and right doors are rotated on the center of the hydraulic jack. At this time, even if the main shaft is rotated, the outer ring 16 is gradually lowered without rotating, and is lowered so as to fill the gap in the bottom. Therefore, the left and right main shafts 7 and 8 are free from hydraulic pressure without receiving resistance from the swooping ball screw. The center of the jack 33 can be rotated, so that the left and right doors 5 and 6 can be opened with a small force.

左右の扉５及び６が全開すると扉固定装置３４の扉停止棒４０及び４１で固定した後、油圧ジャッキ３３を取外す。  When the left and right doors 5 and 6 are fully opened, the hydraulic jacks 33 are removed after fixing with the door stop bars 40 and 41 of the door fixing device 34.

上部軸受１０及び１２に蔓巻ボールねじ１４及び１５を使用することにより十数米の広幅の重い扉も軽く閉鎖することが可能になり、又、この防水装置を横に並べて各々の主軸の上に歯車を固定し、隣接する装置の主軸の歯車を噛合わせることにより、同時に両装置の扉を閉鎖することが可能になる、従って広い河口、漁港入口の閉鎖も可能になる。  By using the conical ball screws 14 and 15 for the upper bearings 10 and 12, it is possible to lightly close a heavy door with a width of more than a dozen US. Also, this waterproof device is placed side by side on each main shaft. By fixing the gears to each other and engaging the gears of the main shafts of the adjacent devices, it is possible to close the doors of both devices at the same time, and thus it is possible to close the wide river mouth and the fishing port entrance.

Significant construction costs are required.

本発明は津波の堤防又は堤防の機能を持つ道路への溢水、津波の河川入口への浸水又は河川上流よりの雨水や洪水等を異常時の増水を利用して自動的に防水を行うものである。  The present invention automatically waterproofs tsunami dikes or floods on roads with dike functions, flooding tsunamis into river inlets, rainwater or flooding from upstream of rivers, etc. by using increased water during abnormal times. is there.

本発明の防水装置の構造は両開きの左右の扉５及び６を取付けた左右の主軸７及び８を、左右の上部軸受１０及び１２と左右の下部軸受１８及び２０によって左右の壁３及び４に沿うて垂直に設置する。  In the structure of the waterproof device of the present invention, left and right main shafts 7 and 8 to which left and right doors 5 and 6 having double doors are attached are attached to left and right walls 3 and 4 by left and right upper bearings 10 and 12 and left and right lower bearings 18 and 20, respectively. Install vertically.

そしてこれの左右の主軸を左右の扉５及び６の設置場所の地下の波受室２２内まで延長して、ここに長尺波受板２４及び２５を各扉と約４５度ずらした位置に固定した後、その各々の先端に左右の短尺波受板２６及び２７を蝶番２８及び２９により連結し、この左右の短尺波受板を中央の蝶番３０で揺動しうるよう連結して一本の波受帯２３を形成し、波受室２２に津波が押寄せた時、この波受帯２３はこれを受けて押流されて左右の主軸７及び８に固定した左右の扉５及び６を左回転又は右回転させる。  The left and right main shafts are extended into the underground wave receiving chamber 22 where the left and right doors 5 and 6 are installed, and the long wave receiving plates 24 and 25 are shifted from the doors by about 45 degrees. After fixing, the left and right short wave receiving plates 26 and 27 are connected to the respective tips by hinges 28 and 29, and the left and right short wave receiving plates are connected so as to be swingable by the central hinge 30. Left and right doors 5 and 6 fixed to the left and right main shafts 7 and 8 when the tsunami is pushed into the wave receiving chamber 22. Rotate left or right.

この時左右の長尺波受板２４及び２５の下辺には左右の底板付扇形歯車３１及び３２が取付けられており、これらが互いに噛合うことにより、左右の主軸７及び８は常に同角速度で反対方向に回転する、従って左右の扉５及び６は左右より同時に閉鎖されるようになる。  At this time, fan gears 31 and 32 with left and right bottom plates are attached to the lower sides of the left and right long wave receiving plates 24 and 25, respectively, so that the left and right main shafts 7 and 8 always have the same angular velocity. It rotates in the opposite direction, so the left and right doors 5 and 6 are closed simultaneously from the left and right.

図３より図６は左扉５の左主軸７の左上部軸受１０を左蔓巻ボールねじ１４の構造にし、開扉時、閉扉時、閉扉時中に左扉をジャッキで突上げた時、及びジャッキで突上げ中、これを開扉した時の作動を示す断面拡大図である。  From FIG. 3 to FIG. 6, the left upper bearing 10 of the left main shaft 7 of the left door 5 has the structure of the left swirl ball screw 14, and when the left door is pushed up with a jack during opening, closing, and closing, FIG. 5 is an enlarged cross-sectional view showing an operation when the door is opened while being pushed up with a jack.

左扉５の左上部軸受１０を緩勾配の左蔓巻ボールねじ１４の構造、右扉６の右上部軸受１２を緩勾配の右蔓巻ボールねじ１５の構造にすることによって重い左右の扉５及び６はその自重によりねじ面に沿うて下降しながら、扉の閉じる方向に向って左回転又は右回転しようとする、この回転力を扉固定装置３４の扉停止棒４０及び４１で押留めておく、扉固定装置３４の構造は長尺軸４２を左右の支点３８及び３９で揺動可能に支持し、これに左右の浮体３５を取付けた支持棒３６及び３７を取付け、津波により浮体３５が持上げられると支持棒の長尺軸４２への取付位置の反対側の支持棒の先端部が引下げられ、それに連結した左右の扉停止棒４０及び４１が同時に引き下げられて、左右の扉の拘束が解かれるので上記の回転力が復活して、波受帯２３が津波の力により左右の扉を閉じようとする作動を助成するようになる。By making the left upper bearing 10 of the left door 5 a structure of the left vine ball screw 14 with a gentle gradient and the right upper bearing 12 of the right door 6 with a structure of the right vine ball screw 15 of a gentle gradient, the heavy left and right doors 5. And 6 are held down by the door stop rods 40 and 41 of the door fixing device 34 so as to rotate leftward or rightward in the closing direction of the door while descending along the screw surface by its own weight. The structure of the door fixing device 34 is such that the long shaft 42 is swingably supported by the left and right fulcrums 38 and 39, and the support rods 36 and 37 to which the left and right floating bodies 35 are attached are attached thereto. When lifted, the tip of the support bar on the opposite side of the mounting position of the support bar to the long shaft 42 is pulled down, and the left and right door stop bars 40 and 41 connected thereto are pulled down simultaneously , thereby restraining the left and right doors. The above rotational force will be restored Wave 受帯 23 comes to funding the operation to try to close the door of the left and right by the force of the tsunami.

しかし開扉のときは上記と逆にねじ面に逆のぼる必要があるために容易ではない、従って開扉に先立って、左右の主軸７及び８の底面のセンター孔９を油圧ジャッキ３３等により突上げて左右の蔓巻ボールねじの外輪１６の底に隙間を作った後、左右の主軸７及び８を油圧ジャッキ３３のセンターの上で回転することにより左右の扉５及び６を小さな力で開くことを可能にする。  However, when opening the door, it is not easy because it is necessary to go back to the threaded surface contrary to the above. Therefore, before opening the door, the center holes 9 on the bottom surfaces of the left and right main shafts 7 and 8 are projected by the hydraulic jack 33 or the like. After raising and making a gap in the bottom of the outer ring 16 of the left and right swoop ball screws, the left and right doors 5 and 6 are opened with a small force by rotating the left and right main shafts 7 and 8 on the center of the hydraulic jack 33.

左右の扉５及び６は左右の主軸７及び８に取付けて両開きするように、そしてこれら左右の主軸を左右の扉５及び６の設置場所の地下の波受室２２内まで延長して、ここに左右の長尺波受板２４及び２５を各扉と約４５度ずらした位置に固定した後、その各々の先端に左右の短尺波受板２６及び２７を蝶番２８及び２９により連結し、この左右の短尺波受板を中央の蝶番３０で揺動しうるよう連結して、一本の波受帯２３を形成し、波受室２２に津波が押寄せた時、この波受帯２３はこれを受けて押流されて左右の主軸７及び８に固定した左右の扉５及び６を左回転又は右回転させる。  The left and right doors 5 and 6 are attached to the left and right main shafts 7 and 8 so as to open both sides, and these left and right main shafts are extended into the underground wave reception chamber 22 at the installation location of the left and right doors 5 and 6. The left and right long wave receiving plates 24 and 25 are fixed at positions shifted by about 45 degrees from the doors, and the left and right short wave receiving plates 26 and 27 are connected to the respective tips by hinges 28 and 29. The left and right short wave receiving plates are connected so as to be swingable by a central hinge 30 to form a single wave receiving band 23. When a tsunami is pushed into the wave receiving chamber 22, the wave receiving band 23 is In response to this, the left and right doors 5 and 6 fixed to the left and right main shafts 7 and 8 are swung left or right.

左右の扉の一方が早く閉じ始めると、この扉を押して流れる水は片方の扉の裏に流れ込み、その扉の閉鎖を妨げることになる、この現象を避けるため左右の長尺波受板２４及び２５の下辺には左右の底板付扇形歯車３１及び３２が取付けられており、これらが互に噛合うことにより左右の主軸７及び８は常に同角速度で反対方向に回転する、従って左右の扉５及び６は左右より同時に閉鎖されるようにする。  When one of the left and right doors begins to close quickly, the water that flows through the door flows into the back of one door and prevents the door from closing. To avoid this phenomenon, the left and right long wave receiving plates 24 and Left and right fan-shaped gears 31 and 32 are attached to the lower side of 25, and the left and right main shafts 7 and 8 always rotate in the opposite direction at the same angular speed by engaging with each other. And 6 are closed simultaneously from the left and right.

左扉５の左上部軸受１０を緩勾配の左蔓巻ボールねじ１４の構造、右扉６の右上部軸受１２を緩勾配の右蔓巻ボールねじ１５の構造にすることによって重い左右の扉５及び６はその自重によりねじ面に沿うて下降しながら、扉の閉じる方向に向って左回転又は右回転しようとする、この回転力を扉固定装置３４の扉停止棒４０及び４１で押留めておく、扉固定装置３４の構造は長尺軸４２を左右の支点３８及び３９で揺動可能に支持し、これに左右の浮体３５を取付けた支持棒３６及び３７を取付け、津波により浮体３５が持上げられると支持棒の長尺軸４２への取付位置の反対側の支持棒の先端部が引下げられ、それに連結した左右の扉停止棒４０及び４１が同時に引き下げられて、左右の扉の拘束が解かれるので上記の回転力が復活して、波受帯２３が津波の力により左右の扉を閉じようとする作動を助成するようになる。By making the left upper bearing 10 of the left door 5 a structure of the left vine ball screw 14 with a gentle gradient and the right upper bearing 12 of the right door 6 with a structure of the right vine ball screw 15 of a gentle gradient, the heavy left and right doors 5. And 6 are held down by the door stop rods 40 and 41 of the door fixing device 34 so as to rotate leftward or rightward in the closing direction of the door while descending along the screw surface by its own weight. The structure of the door fixing device 34 is such that the long shaft 42 is swingably supported by the left and right fulcrums 38 and 39, and the support rods 36 and 37 to which the left and right floating bodies 35 are attached are attached thereto. When lifted, the tip of the support bar on the opposite side of the mounting position of the support bar to the long shaft 42 is pulled down, and the left and right door stop bars 40 and 41 connected thereto are pulled down simultaneously to restrain the left and right doors. The above rotational force will be restored Wave 受帯 23 comes to funding the operation to try to close the door of the left and right by the force of the tsunami.

左右の上部軸受１０及び１２に左右の蔓巻ボールねじ１４及び１５を使用した場合、閉じられた左右の扉５及び６を開けるためには、図５に示すように左右の主軸７及び８の底面のセンター孔９を油圧ジャッキ３３、スクリュージャッキ等により突上げて左右の蔓巻ボールねじの外輪１６の底に隙間を作る。  When the left and right swirl ball screws 14 and 15 are used for the left and right upper bearings 10 and 12, in order to open the closed left and right doors 5 and 6, as shown in FIG. The center hole 9 on the bottom surface is pushed up by a hydraulic jack 33, a screw jack or the like to create a gap in the bottom of the outer ring 16 of the left and right swirl ball screws.

次に図６に示すように左右の扉の主軸７及び８を油圧ジャッキのセンター等の上で回転させる。このとき主軸を回転させても外輪１６は回転せずに次第に降下して底の隙間は埋めるように降下する、従って左右の主軸７及び８は蔓巻ボールねじによる抵抗を受けることなく自由に油圧ジャッキ３３のセンターの上を回転することが出来、従って左右の扉５及び６は小さな力で開くことが可能になる。  Next, as shown in FIG. 6, the main shafts 7 and 8 of the left and right doors are rotated on the center of the hydraulic jack. At this time, even if the main shaft is rotated, the outer ring 16 is gradually lowered without rotating, and is lowered so as to fill the gap in the bottom. Therefore, the left and right main shafts 7 and 8 are free from hydraulic pressure without receiving resistance from the swooping ball screw. The center of the jack 33 can be rotated, so that the left and right doors 5 and 6 can be opened with a small force.

左右の扉５及び６が全開すると扉固定装置３４の扉停止棒４０及び４１で固定した後、油圧ジャッキ３３を取外す。  When the left and right doors 5 and 6 are fully opened, the hydraulic jacks 33 are removed after fixing with the door stop bars 40 and 41 of the door fixing device 34.

上部軸受１０及び１２に蔓巻ボールねじ１４及び１５を使用することにより十数米の広幅の重い扉も軽く閉鎖することが可能になり、又、この防水装置を横に並べて各々の主軸の上に歯車を固定し、隣接する装置の主軸の歯車を噛合わせることにより、同時に両装置の扉を閉鎖することが可能になる、従って広い河口、漁港入口の閉鎖も可能になる。  By using the conical ball screws 14 and 15 for the upper bearings 10 and 12, it is possible to lightly close a heavy door with a width of more than a dozen US. Also, this waterproof device is placed side by side on each main shaft. By fixing the gears to each other and engaging the gears of the main shafts of the adjacent devices, it is possible to close the doors of both devices at the same time, and thus it is possible to close the wide river mouth and the fishing port entrance.
