A gasket is installed between the bottom plate 5, the plurality of flashboards 3 and the top plate 2. - 特許庁A U-shaped curved tube 4 is fixed to both ends of the flashboard 3 . The upper end of each curved tube 4 communicates with a first launch hole 16 and a first drain hole 17 installed in the flashboard 3 . Between the flashboards 3, the first launch hole 16 on one flashboard 3 and the first drain hole 17 on the other flashboard 3 communicate with each other.

A second water launching hole 15 is installed in the top plate 2 , one end of the second water launching hole 15 communicates with the upper end of the curved path, and the other end of the second water launching hole 15 communicates with the upstream surface of the top plate 2 . are doing. A valve is installed in the second launch hole 15 .

前段の水門室内にある水を後段の水門室内に排出したい場合、弁を開放でき、前段の水門室内の水が第二進水孔１５及び彎曲通道を通過した後、第二排水孔１８から後段の水門室内に排出する。これにより、後段の水門室内の高い水頭の水を低所の水に変更して、低所の水により充満し、且つ彎曲通道を利用して水流速度を削減し、極大で高い水頭の水流による後段の水門室の底板５の衝撃を弱める。 When the water in the front gate chamber is to be discharged into the rear gate chamber, the valve can be opened, and the water in the front gate chamber passes through the second water launch hole 15 and the curved passage, and then the second drain hole 18 to the rear stage. discharge into the gate chamber. As a result, the high head water in the latter stage of the water gate chamber is changed to the low water, and the low water is filled, and the curved passage is used to reduce the water flow velocity, resulting in the maximum and high head water flow. To weaken the impact of the bottom plate 5 of the water gate chamber in the latter stage.

フラッシュボード３を吊り上げる必要がある場合、吊り索が二つの湾曲チューブ４に接続させてフラッシュボード３を吊り上げることができる。 When the flashboard 3 needs to be lifted, a sling can be connected to the two curved tubes 4 to lift the flashboard 3.

シリンダー１２が、弁孔１３内に運動するプランジャー１４を駆動する過程で、第二進水孔１５の急速な開閉を容易にする。 Cylinder 12 facilitates rapid opening and closing of secondary launch hole 15 in the process of driving plunger 14 moving into valve hole 13 .

フラッシュボード３の上流面に複数の制限管７が取り付けられ、各制限管７内にゴム製気嚢８が設置され、ゴム製気嚢８が急速ジョイント及びホース１１により浮標６と接続される。ホース１１が気源と連通させた後、圧縮空気がゴム製気嚢８内に入り、ガスをゴム製気嚢８に補給して浮力を生じ、フラッシュボード３及び天板２を持ち上げ、フラッシュボード３と底板５との間又はフラッシュボード３とフラッシュボード３との間に隙間を形成させる。前段の水門室２０にある水が隙間を貫通して急速に後段の水門室１９に入り、後段の水門室の水の急速的充満を実現し、同時に後段の水門室の底部に垂直に衝撃する水流を後段の水門室１９に水平に入ることに改め、水流による後段の水門室の底板５の衝撃を弱める。 A plurality of restriction tubes 7 are attached to the upstream surface of the flashboard 3 , a rubber bladder 8 is installed in each restriction tube 7 , and the rubber bladder 8 is connected with the buoy 6 by a quick joint and a hose 11 . After the hose 11 communicates with the air source, the compressed air enters the rubber bladder 8 and replenishes the gas to the rubber bladder 8 to create buoyancy, lift the flashboard 3 and the top plate 2, and lift the flashboard 3 and the top plate 2. A gap is formed between the bottom plate 5 or between the flashboards 3 and 3. The water in the front sluice chamber 20 passes through the gap and rapidly enters the rear sluice chamber 19, realizing rapid filling of the rear sluice chamber with water, and at the same time vertically impacting the bottom of the rear sluice chamber. The water flow is changed to horizontally enter the water gate chamber 19 in the latter stage, and the impact of the water flow on the bottom plate 5 of the water gate chamber in the latter stage is weakened.

各ホース１１に締切弁９及び圧力表１０が取り付けられる。図２の示すように、各ゴム製気嚢８にガスを補給する過程で、圧力表１０を観察してゴム製気嚢８のガス補給量を確定できる。これにより、ゴム製気嚢８の浮力を調整し、フラッシュボード３と底板５との間隙を調整する。 A shut-off valve 9 and a pressure table 10 are attached to each hose 11 . As shown in FIG. 2, in the process of refilling each rubber bladder 8, the pressure table 10 can be observed to determine the amount of gas refilled in the rubber bladder 8. As shown in FIG. This adjusts the buoyancy of the rubber bladder 8 and adjusts the gap between the flashboard 3 and the bottom plate 5 .

水門室内の排水による止水洗浄ストップログゲートを使用して水門室を排水する方法は、弁を開け、前段の水門内にある水が、第二進水孔１５、彎曲通道及び第二排水孔１８を通過した後、後段の水門室内に流入し、後段の水門室内の水位が底板５高さ１／２を上回るまで上昇したときに、各ゴム製気嚢８内にガスを補給し、ゴム製気嚢８が各段のフラッシュボード３をアップコンバータして作動させることで、前段の水門内の水を、フラッシュボード３とフラッシュボード３との間隙又はフラッシュボード３と底板５との間隙を介して後段の水門室１９内の水面に流入させる。これにより、流入した水流による後段の水門室の底部への直接の衝撃を回避できる。 Stop water washing by draining water in the water gate room The method of draining the water gate room using the log gate is to open the valve and the water in the water gate in the previous stage flows through the second launch hole 15, the curved passage and the second drainage hole. 18, it flows into the water gate chamber of the latter stage, and when the water level in the water gate chamber of the latter stage rises to exceed 1/2 of the height of the bottom plate 5, the gas is replenished in each rubber bag 8, and the rubber The air sac 8 up-converts the flashboards 3 of each stage to operate, so that the water in the water gate of the previous stage flows through the gap between the flashboards 3 and the flashboards 3 or the gap between the flashboards 3 and the bottom plate 5. It is caused to flow into the water surface in the water gate chamber 19 in the latter stage. As a result, direct impact on the bottom of the subsequent sluice gate chamber by the inflowing water flow can be avoided.
