本発明は、ポンプの吸水用のポンプ吸水槽に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pump water suction tank for water suction of a pump.
この種のポンプ吸水槽の従来のものは、例えば第４図、
第５図、第６図に示す如く、河川の如き取水源から、コ
ンクリート構造物による分離部２により隔てられて吸水
槽３が設けられている。取水源ｌと吸水槽３とは、分離

が吸水槽３に取り込まれるようになっている。５はポン
プであり、モータ６により駆動され吸水槽３から吸水し
、送水管７に水を送るようになっている。Conventional pump suction tanks of this type are shown in Fig. 4, for example.
As shown in FIGS. 5 and 6, a water absorption tank 3 is provided separated from a water intake source such as a river by a separation section 2 made of a concrete structure. The water intake source 1 and the water absorption tank 3 are connected by an intake channel 4 that passes through the separation part 2, so that water is taken from the water intake source 1 into the water absorption tank 3. A pump 5 is driven by a motor 6 to suck water from the water absorption tank 3 and send water to the water pipe 7.
しかしながら、このよ゛うな従来のポンプ吸水槽におい
て、ポンプの容量増大、或いはポンプの増設などにより
ポンプの総揚水量を増大させる場合に、取水路断面積が
そのままであると、吸水槽３内の水位が低下して揚水が
不可能となる。However, in such a conventional pump water suction tank, when the total pumping amount of the pump is increased by increasing the pump capacity or adding more pumps, if the cross-sectional area of the intake channel remains the same, the amount of water in the water suction tank 3 will increase. The water level will drop and pumping will become impossible.
例えば、成るポンプにより揚水を行っているときに、取
水源１と吸水槽３との水位の差が ｈｌであったとする
。このような吸水槽３に人容その、ポンプを設置して揚
水量を増大せしめると、水位差は増大して ｈ２となる
。この ｈ２の水位差においてポンプ５の吸水人口が水
面から空気を吸い込むようになると揚水は不可能となる
。For example, suppose that the difference in water level between water intake source 1 and water absorption tank 3 is hl when water is being pumped by a pump consisting of: When a pump is installed in such a water suction tank 3 to increase the amount of water pumped, the water level difference increases to h2. If the water suction population of the pump 5 begins to suck air from the water surface at this water level difference of h2, pumping becomes impossible.
このように、揚水壇増大をはかるときに水位低下を防ぎ
、揚水を可能ならしめるためには取水路４の断面積を増
加せねばならない。しかしながら、そのためには分離部
２を構成するコンクリート構造物をはつって取水路４を
拡大せねばならず、膨大な工事の手間と費用がかかる。In this way, when increasing the pumping platform, the cross-sectional area of the intake channel 4 must be increased in order to prevent a drop in the water level and make pumping possible. However, for this purpose, it is necessary to expand the intake channel 4 by enlarging the concrete structure constituting the separation section 2, which requires a huge amount of work and cost.
その上に構造物の強度面からも拡大工事の施工限界が生
ずる場合もある、などの問題点を有する。In addition, there are other problems, such as the fact that there may be limits to the expansion work due to the strength of the structure.
本発明は、このような従来のものの問題点を解決し、既

、水位の大幅な低下を生ずることなく、また、施工の手
間も費用も僅少であるポンプ吸水槽を提供することを目
的とするものである。The present invention solves these problems with conventional pumps, and even when attempting to increase the amount of pumped water in an existing pump water suction tank, the water level does not drop significantly, and the construction effort and cost are minimal. The purpose is to provide a certain pump water suction tank.
本発明は、上記の問題点を解決するための手段として、

In a pump water intake tank that is separated from a water intake source by a separation part and that takes water through an intake channel that passes through the separation part, a siphon pipe installed above the separation part at a position higher than the water surface It is an object of the present invention to provide a pump water suction tank characterized in that the water intake source and the water suction tank are connected.
本発明の実施例を図面により説明する。 Embodiments of the present invention will be described with reference to the drawings.

しめるようになっている。In FIGS. 1, 2, and 3, 8 is a siphon pipe installed above the separation section 2 at a position higher than the water surface 9.10, and connects the water intake St and the water absorption tank 3. There is. The connecting pipe section 11 at the top of the siphon tube 8 has an upward slope, and a small hole 12 is provided at the top of the connecting pipe section 11 to connect the air reservoir chamber 1.
3. A water level gauge 14 is provided in the air reservoir chamber 13, and when the water level in the air reservoir chamber 13 falls below a predetermined water level, a vacuum pump 15 is activated to restore the water level. Make sure it is always filled with water. Reference numeral 16 denotes a vacuum break valve, which is activated when the pump 5 is stopped to introduce outside air into the air reservoir chamber 13 and into the siphon tube 8 to stop the siphon action.

The air inside the siphon tube 8 is removed and the siphon tube 8 is filled with water. Next, when the pump 5 is started, the water level in the water suction tank 3 decreases, and water from the water intake source I flows into the water suction tank 3 through the intake channel 4 and the siphon pipe 8.
このとき、取水断面積にはサイフオン管８の断面積が加
わるので吸水槽３の水位の大幅な低下が生ずることなく
、大量の揚水を行うことができる。At this time, since the cross-sectional area of the siphon pipe 8 is added to the water intake cross-sectional area, a large amount of water can be pumped without causing a significant drop in the water level in the water absorption tank 3.

It's over.
また、コンクリート構造物の強度を損ねるおそれもない

When more than a predetermined amount of air is accumulated, the vacuum pump 15 is activated to perform exhaustion.

果を奏するものである。Effects of the invention] According to the present invention, even when pumping water in a human-like manner using an existing water absorption tank, the water intake cross-sectional area can be reduced with a simple structure without machining the concrete structure. To provide a pump water suction tank that can increase the water intake tank, significantly reduce the labor and cost of construction, and that can be increased arbitrarily without being limited by the cross section of the intake channel without fear of compromising the strength of the separation part. It is possible to do so, and has extremely great practical effects.
