するもので゛ある。In other words, this idea is a water intake device in which the upper end of the dam crest is set as the planned spillway water level, and the intake pipe is installed in the water in front of it. The main objective is to make it possible to reduce the
以下、この考案の実施例を図面に基づいて詳細に説明す
る。Hereinafter, embodiments of this invention will be described in detail based on the drawings.
図面において、１はダム貯水池などの堰堤、２はクレス
ト、３は上向開口の取水管、４は放水管路で、取水管３
は堰堤コンクリートにクレスト２の上流側に立設せられ
、その下端が放水管路４に連結されている。In the drawing, 1 is a weir such as a dam reservoir, 2 is a crest, 3 is an upward-opening intake pipe, 4 is a water discharge pipe, and intake pipe 3
is erected on the dam concrete on the upstream side of the crest 2, and its lower end is connected to the water discharge pipe 4.
５は放水管路４の端部に設けられた流量調整ゲートで制
水を行なわしめうろこと勿論であり、スライドゲートの
みならず、他の形式のゲートが利用しうろこと当然で゛
ある。Reference numeral 5 is, of course, a scale that controls water by a flow rate regulating gate provided at the end of the water discharge pipe 4, and it is natural that other types of gates can be used, not just slide gates.
なお、放水管路４の途中には、下面に段部６が設けられ
、この段部６から下流側は、下面が上流側よりも高くな
っており、水流がはね上がって、流水と共に取水管３の
上部取水口３Ａから吸い込んだ空気を、この段部６から
下流には流さないようせき止めるよう作用する。In addition, a step 6 is provided on the lower surface in the middle of the water discharge pipe 4, and on the downstream side from this step 6, the lower surface is higher than the upstream side, and the water flow splashes up and is removed together with the flowing water. It acts to stop the air sucked in from the upper water intake port 3A of the water pipe 3 from flowing downstream from this stepped portion 6.
７は取水開口３Ａの外周堰堤１Ａ上に立設された支柱で
、この支柱７の上端には中央に空気抜孔８をもった略傘
形の天板９が取付けられている。Reference numeral 7 denotes a post erected on the outer peripheral dam 1A of the water intake opening 3A, and a generally umbrella-shaped top plate 9 with an air vent hole 8 in the center is attached to the upper end of this post 7.
また、天板９の上側にはこれを覆うように覆蓋板１０が
所定の間隔を保持すべく間隔保持部材１１を介して取付
けられている。Further, a cover plate 10 is attached to the upper side of the top plate 9 via a spacing member 11 so as to cover the top plate 9 and maintain a predetermined spacing.
なお、覆蓋板１０は、天板９と同じ形状に形或せられ、
取水管３内から前記空気抜孔８を通って天板９との間に
導びかれた空気が覆蓋板１０の外周端縁１０Ａから排出
されるようになっている。Note that the cover plate 10 is shaped in the same shape as the top plate 9,
Air introduced from inside the water intake pipe 3 through the air vent hole 8 and between the top plate 9 and the top plate 9 is discharged from the outer peripheral edge 10A of the cover plate 10.
１２は支柱７の上・中・下部に、これらを互に連結する
ように固着された連結梁で、この連結梁１２の外側には
、平板からなるスクリンバ−１３が所定の間隔で全周面
に取付けられ、除塵スクリーン１４が形威されている。Reference numeral 12 denotes connecting beams fixed to the upper, middle, and lower parts of the pillars 7 so as to connect these to each other, and on the outside of the connecting beams 12, scrimbars 13 made of flat plates are installed at predetermined intervals on the entire circumference. A dust removal screen 14 is installed on the screen.
１５はゲート開閉油圧シリンダ、１６はゲート開閉ロツ
ドである。15 is a gate opening/closing hydraulic cylinder, and 16 is a gate opening/closing rod.
なお、前記クレスト２の天端は、計画洪水吐水位Ｌと一
致せしめられ、前記覆蓋板１０の天端は、この計画洪水
吐水位よりも下方に位置するように設置されている。The top of the crest 2 is made to coincide with the planned spillway water level L, and the top of the cover plate 10 is installed so as to be located below this planned spillway water level.
この考案によれば、取水口３Ａから流入した水は、放水
管路４に至り、段部６に当って放水管路４の天壁に衝突
して空気の逃げ道を塞ぎ、下流に流れて、ゲート５部分
を経て放流される。According to this invention, water flowing in from the water intake port 3A reaches the water discharge pipe 4, hits the stepped portion 6, collides with the ceiling wall of the water discharge pipe 4, blocks the air escape route, and flows downstream. The water is discharged through Gate 5.
したがって、取水管３および放水管路４内の空気は、取
水管３内を上昇して天板９中夫の空気抜孔８から覆蓋板
１０との間を経て大気中に排出される。Therefore, the air in the water intake pipe 3 and the water discharge pipe 4 rises inside the water intake pipe 3 and is discharged into the atmosphere through the space between the air vent hole 8 of the top panel 9 and the cover plate 10.
そのため、流量係数が小さくなり、流量が多くなる。Therefore, the flow rate coefficient becomes smaller and the flow rate increases.
そして、取水口３Ａよりも水位が高いときは、貯水は放
水され、その水量はゲート５により必要に応じて調整さ
れる。When the water level is higher than the water intake port 3A, the stored water is discharged, and the amount of water is adjusted by the gate 5 as necessary.
また、水位が計画洪水吐水位を越えると、貯水はクレス
ト２を溢流する。Furthermore, when the water level exceeds the planned spillway water level, the stored water overflows the crest 2.

さらに、取水口の外周にこれを囲む除塵スクリーンが設
けられているので、除塵はもとより危険を防止すること
ができる。As mentioned above, this design has a stepped section on the bottom surface of the water discharge pipe, a top plate with an air vent above the water intake, and a cover plate on the top plate. The air in the water pipes and water discharge pipes is released into the atmosphere from the outer peripheral edge of the cover plate through the air vent hole, and the flow rate coefficient becomes smaller. It can be made smaller, and a flow rate adjustment gate is installed at the end of the water discharge pipe, so you can adjust the amount of water discharged as needed.
Furthermore, since a dust removal screen is provided around the outer periphery of the water intake, it is possible not only to remove dust but also to prevent danger.
