Abstract

PROBLEM TO BE SOLVED: To provide a water gate for enabling passing of a small-sized ship in normal time, and automatically closing a river without using electric power and its other power source in an abnormal water increase such as a Tsunami.SOLUTION: An upper bearing 16 is installed on a main column 5 of an outer frame of a water gate, and a main shaft 15 of an opening door 8 is suspended by this bearing. In a structure of a water gate, when surging a Tsunami, a floating body of a door fixing device floats up, and a floating body support bar also floats up, and a projection installed in this separates from a fixing latch of the door, so that torque is restored since restriction of the door is released, and power of the Tsunami is also added to the door, and the door 8 automatically rotates in the closing direction, and a tip arm 13 of its door stops by striking on a door stop 7 of an auxiliary column 6, and oil under a piston of a pulling-up cylinder 11 is released by this operation, and a lower end part of the door is closed by descending up to above a door sill 4 of a river bed 3.SELECTED DRAWING: Figure 5

Description

津波等による増水を自動的に防御する開き扉の水門の構造。  The structure of a sluice gate with an open door that automatically protects against water increase due to tsunami.

低い堤防により護られた河川に津波等による増水が押寄せたとき、これを防ぐため新たに津波対策用の高い防潮堤が必要となる、そしてここには平時には船の通行を許し、増水時には即時に閉鎖できる水門の併設が必要である。  When a flood caused by a tsunami rushes into a river protected by a low embankment, a new high tidal embankment for tsunami countermeasures is required to prevent this, and here, ships are allowed during normal times, It is necessary to install a sluice that can be closed immediately.

平時は小型の船の通行を可能にし、津波等の異常増水には電力その他の動力源を使用せずに、この増水により自動的に遅滞なく河川等を閉鎖する水門を開発しようとする。  During normal times, small ships will be able to pass through, and without using electric power or other power sources for abnormal water increases such as tsunamis, this water increase will automatically close rivers without delay.

本発明は片開きの扉，及び両開きの扉の水門の構造において、水門の外枠の主柱５に上部軸受１６を取付けて、この軸受により開き扉８の主軸１５を吊下げ、そして下部軸受２２により垂直に保持する、そして扉の下端部１０を扉本体より分離して本体に沿うて昇降できるよう取付け、扉が開かれている位置にあるときは、その下端部は河底より数十糎の高さに保持されるよう引上げ用シリンダー１１により引上げておく。  In the structure of the single door and the sluice of the double door, the present invention attaches the upper bearing 16 to the main pillar 5 of the outer frame of the sluice, suspends the main shaft 15 of the open door 8 by this bearing, and lower bearing. The lower end 10 of the door is separated from the door body so that it can be moved up and down along the body. When the door is in the open position, the lower end is several tens of feet from the riverbed. It is pulled up by the pulling cylinder 11 so as to be held at the height of the ridge.

主軸の上部軸受を蔓巻ボールねじ１７の構造にすることにより、重い扉はその自重によりねじ面に沿うて下降しながら閉じる方向に向って回転しようとする。  By making the upper bearing of the main shaft into the structure of the wrapping ball screw 17, the heavy door tends to rotate toward the closing direction while descending along the screw surface by its own weight.

上記の回転力を扉固定装置２４の浮体支持棒２６に取付けた突起２７と、扉の固定用掛金２３との噛合せによって押留めておき、津波等が押寄せた時、扉固定装置の浮体２５が浮上がり、そして浮体支持棒２６も浮上がり、これに取付けた突起２７が扉の固定用掛金より離脱することにより、扉の拘束が解かれるので上記の回転力が復活し、又扉に津波の力も加わって、扉は自動的に閉鎖の方向に回転し、その扉の先端腕１３は副柱６の戸当り７に当って停止する、この作動により戸当り近くに取付けられているストップ弁（１４）を押し開き、引上げ用シリンダー１１のピストン１２下の油を逃して、ピストンと共に扉の下端部を河底３の敷居４の上まで降下させ水門を閉鎖する。  The above-mentioned rotational force is held by engagement between the protrusion 27 attached to the floating body support rod 26 of the door fixing device 24 and the fixing hook 23 for fixing the door. 25 is lifted, and the floating body support rod 26 is also lifted, and the protrusion 27 attached thereto is released from the latch for fixing the door, so that the restraint of the door is released, so that the rotational force is restored and the door is restored. Due to the force of the tsunami, the door automatically rotates in the closing direction, and the tip arm 13 of the door stops against the door stop 7 of the sub pillar 6. This stop is attached near the door stop by this operation. The valve (14) is pushed open, oil under the piston 12 of the pulling cylinder 11 is released, and the lower end of the door is lowered onto the sill 4 of the river bed 3 together with the piston to close the sluice.

本発明の開き扉の水門によって津波等による河川の増水を自動的に、遅滞なく閉鎖することが可能になる、猶河川に多少の土砂が堆積しているときも閉鎖可能である、又堤防下の車両通用門に設置し、津波の増水を自動的に防ぐことが可能である。  The sluice of the hinged door of the present invention can automatically close the increase of river due to tsunami, etc. without delay, it can be closed even when some earth and sand is accumulated in the grace river, or under the dike It is possible to prevent the tsunami from flooding automatically.

本発明は片開きの扉，及び両開きの扉の水門の構造において、水門の外枠の主柱５に上部軸受１６を取付けて、この軸受により開き扉８の主軸１５を吊下げ、そして下部軸受２２により垂直に保持する、そして扉の下端部１０を扉本体より分離して本体に沿うて昇降できるよう取付け、扉が開かれている位置にあるときは、その下端部は河底より数十糎の高さに保持されるよう引上げようシリンダー１１により引上げておく、これによって河底の土砂に邪魔されずに扉を閉める位置まで回転させることが可能となる。  In the structure of the single door and the sluice of the double door, the present invention attaches the upper bearing 16 to the main pillar 5 of the outer frame of the sluice, suspends the main shaft 15 of the open door 8 by this bearing, and lower bearing. The lower end 10 of the door is separated from the door body so that it can be moved up and down along the body. When the door is in the open position, the lower end is several tens of feet from the riverbed. The cylinder 11 is pulled up so as to be held at the height of the reed, so that it can be rotated to a position where the door is closed without being obstructed by the sediment on the riverbed.

主軸の上部軸受を蔓巻ボールねじ１７の構造にすることにより、重い扉はその自重によりねじ面に沿うて下降しながら閉じる方向に向って回転しようとする。  By making the upper bearing of the main shaft into the structure of the wrapping ball screw 17, the heavy door tends to rotate toward the closing direction while descending along the screw surface by its own weight.

上記の回転力を扉固定装置２４の浮体支持棒２６に取付けた突起２７と、扉の固定用掛金２３との噛合せによって押留めておき、津波等が押寄せた時、扉固定装置の浮体２５が浮上がり、そして浮体支持棒２６も浮上がり、これに取付けた突起２７が扉の固定用掛金より離脱することにより、扉の拘束が解かれるので上記の回転力が復活し、又扉に津波の力も加わって、扉は自動的に閉鎖の方向に回転し、その扉の先端腕１３は副柱６の戸当り７に当って停止する、この作動により戸当り近くに取付けられているストップ弁（１４）を押し開き、引上げ用シリンダー１１のピストン１２下の油を逃して、ピストンと共に扉の下端部を河底３の敷居４の上まで降下させ水門を閉鎖する。  The above-mentioned rotational force is held by engagement between the protrusion 27 attached to the floating body support rod 26 of the door fixing device 24 and the fixing hook 23 for fixing the door. 25 is lifted, and the floating body support rod 26 is also lifted, and the protrusion 27 attached thereto is released from the latch for fixing the door, so that the restraint of the door is released, so that the rotational force is restored and the door is restored. Due to the force of the tsunami, the door automatically rotates in the closing direction, and the tip arm 13 of the door stops against the door stop 7 of the sub pillar 6. This stop is attached near the door stop by this operation. The valve (14) is pushed open, oil under the piston 12 of the pulling cylinder 11 is released, and the lower end of the door is lowered onto the sill 4 of the river bed 3 together with the piston to close the sluice.

最初、扉が開かれているときは、扉の主軸１５は図６のように蔓巻ボールねじで引上げられた位置にあって、扉が自重により９０度回転して閉じられると、図７のように主軸は少し降下している、次に主軸と扉を図８のように油圧ジャッキ２１により最初の位置まで押上げると、蔓巻ボールねじの外輪は浮上がった状態となり、そして扉を開く位置まで９０度回転を戻すと、外輪は降下して図９の状態になる。  Initially, when the door is opened, the main shaft 15 of the door is in the position pulled up by the vine ball screw as shown in FIG. 6, and when the door is rotated 90 degrees by its own weight and closed, As shown in FIG. 8, when the main shaft and the door are pushed up to the initial position by the hydraulic jack 21 as shown in FIG. 8, the outer ring of the vine ball screw is lifted and the door is opened. When the 90 degree rotation is returned to the position, the outer ring descends to the state shown in FIG.

扉及び主軸は油圧ジャッキ２１の先端に支えられた状態で、開く位置まで戻すために軽い力で戻すことが出来る、そして油圧ジャッキを引下げると主軸は図６の状態に戻る。  The door and the main shaft are supported by the tip of the hydraulic jack 21 and can be returned with a light force to return to the open position. When the hydraulic jack is lowered, the main shaft returns to the state shown in FIG.
