Description

本発明は、例えば河川の橋脚工事や堰堤工事等において、障害物を設けて河川をせき止めたとき上流側に溜った水などをサイホン作用を利用して下流側へと移動させる送液用ポンプに接続される開閉装置、並びにその開閉装置を使用した液体の送液方法に関する。   The present invention provides, for example, a pump for feeding a liquid that moves water accumulated on the upstream side to the downstream side using a siphon action when an obstacle is installed to block the river in river pier construction or dam construction. The present invention relates to a connected switchgear and a liquid feeding method using the switchgear.

例えば河川の橋桁や堰堤等の工事を行なう場合は、図１０に示すように、工事箇所１の上流側及び下流側で、河川を横断する方向に障害物２を設けて締切工事を行っている。上流側に溜った水は、一般にエンジン式発電機３により発電し、水中ポンプ４を駆動してホース５を通して下流側に流している。また、砂防工事においても、同様に、締切工事をした障害物２部分に溜った水は、水中ポンプ４を利用してホース５を通して下流側に流している。   For example, when constructing river bridge girders, dams, etc., as shown in FIG. 10, an obstacle 2 is provided in the direction crossing the river on the upstream side and the downstream side of the construction site 1 to perform the deadline construction. . The water accumulated on the upstream side is generally generated by the engine generator 3, and drives the submersible pump 4 to flow downstream through the hose 5. Similarly, in the sabo work, the water accumulated in the obstacle 2 portion subjected to the deadline construction is made to flow downstream through the hose 5 using the submersible pump 4.

上記工事においては、エンジン式発電機３及び水中ポンプ４を連続して運転するため、つぎのような問題が発生する。
（１）定期的に給油作業を行わなければならないので、保守に手間がかかる。排水作業は昼夜を問わず行なうので、給油作業を行なう作業員の負担が大きい。
（２）エンジンの排ガスにより環境汚染が発生する。
（３）騒音が大きく、特に夜間においては近隣の迷惑になる。
（４）燃費等の運転費用が嵩む。 In the above construction, the engine generator 3 and the submersible pump 4 are continuously operated, and thus the following problems occur.
(1) Since refueling work must be performed regularly, maintenance is troublesome. Since drainage work is performed day and night, the burden on workers who perform refueling work is large.
(2) Environmental pollution occurs due to engine exhaust gas.
(3) Noisy, especially in the vicinity at night.
(4) The operating cost such as fuel consumption increases.

本発明者は、上記の問題の解決を目的として、水中ポンプの稼働時間を短縮して運転費用を節約し、簡単な装置で水を移動させることができる送水装置に使用される送水用ポンプを提供した（特許文献１参照）。   For the purpose of solving the above problems, the present inventor has reduced the operating time of a submersible pump to save operation costs, and a water supply pump used in a water supply device that can move water with a simple device. Provided (see Patent Document 1).

図１１〜図１３に示すように、この送水用ポンプ２０は、障害物の両側に跨設され一方の端部が水中に浸漬され他方側の端部が一方の端部の水位面よりも下方に位置する送水管１４を通じて一方側に溜った水を障害物の他方側へ移動させる送水装置１０に使用されるものであって、水中に浸漬され吐出側が送水管１４の一方の下端部１４ｂに接続された水中ポンプ２１と、この水中ポンプ２１の吐出側を囲んでその外側に設けられる吸水孔２２ａを有する分岐吸水管２２と、前記水中ポンプ２１の吐出側に設けられ前記送水管１４と分岐吸水管２２とを連通する連通孔（図示しない）とを備えたことを特徴とするものである。   As shown in FIGS. 11 to 13, this water supply pump 20 is straddled on both sides of the obstacle, one end is immersed in water, and the other end is below the water level surface of one end. Is used in a water supply device 10 that moves water accumulated on one side to the other side of an obstacle through a water supply pipe 14 located in the water, and is immersed in water and the discharge side is connected to one lower end portion 14b of the water supply pipe 14. A submerged pump 21 connected, a branched water intake pipe 22 having a water suction hole 22a provided around the discharge side of the submersible pump 21, and a branch of the water supply pipe 14 provided on the discharge side of the submersible pump 21 A communication hole (not shown) that communicates with the water absorption pipe 22 is provided.

上記構成を備えた送水用ポンプを用いた場合、該送水用ポンプを初期の期間だけ駆動させれば送水管内の水の流れが定常状態になり、そこで送水用ポンプを停止させれば、サイホン作用によって引き続き、送水が行われるので、水中ポンプの運転時間を著しく短縮することができ、運転費用を節約し、排ガスによる環境汚染や騒音等の公害の発生を防止することができるという優れた効果を奏する。   When a water pump having the above configuration is used, if the water pump is driven only for an initial period, the flow of water in the water pipe becomes a steady state, and if the water pump is stopped there, the siphon action As a result, the submerged pump operation time can be significantly shortened, operating costs can be saved, and pollution such as environmental pollution and noise caused by exhaust gas can be prevented. Play.

また特許文献１には、別の形態として図１２及び図１３に示すように、送水管１４からほぼ直角に分岐吸水管２５を分岐させ、この分岐吸水管２５の支点２６を中心に回動可能とした第２の開閉弁２７を設け、水位に連動して分岐吸水管２５を開閉させるようにした送水用ポンプが示されている。   Further, in Patent Document 1, as shown in FIGS. 12 and 13 as another form, a branched water absorption pipe 25 is branched from a water supply pipe 14 at a substantially right angle, and can be rotated around a fulcrum 26 of the branched water absorption pipe 25. The water supply pump provided with the second on-off valve 27 is configured to open and close the branch water intake pipe 25 in conjunction with the water level.

第２の開閉弁２７は、軟質弾性材例えば軟質ゴム或は合成樹脂から中空体に形成されたフロート状の浮上部２７ａと、分岐吸水管２５の端面に当接する弁座２７ｂを一体に形成したものであるため、構成が簡単であり、分岐吸水管２５の閉鎖時期が的確に実施されて、送水を効率的に実施できるという効果を奏する。   The second on-off valve 27 is integrally formed with a float-like floating portion 27 a formed in a hollow body from a soft elastic material such as soft rubber or synthetic resin, and a valve seat 27 b that comes into contact with the end surface of the branch water absorption pipe 25. Therefore, the configuration is simple, and the closing time of the branch water absorption pipe 25 is accurately performed, and there is an effect that water supply can be efficiently performed.

またこの開閉弁２７によれば、上流側の水位が下がると、該第２の開閉弁２７が分岐吸水管２５を閉鎖（図１３参照）するようになっているので、サイホン作用による送水は一旦停止することになる。その後、水位が上昇すれば、再び第２の開閉弁２７が浮上して分岐吸水管２５が開放され、サイホン作用を利用した送水が再開するので、送水が継続して実施されるという効果も奏する。
特許第３０９９２２７号公報 Further, according to this on-off valve 27, when the water level on the upstream side is lowered, the second on-off valve 27 closes the branch water intake pipe 25 (see FIG. 13), so that water supply by the siphon action is temporarily stopped. Will stop. Thereafter, if the water level rises, the second on-off valve 27 rises again, the branch water intake pipe 25 is opened, and water supply using the siphon action is resumed, so that the water supply is continuously performed. .
Japanese Patent No. 3099227

ところが、上記開閉弁２７の場合、上流側の水位の変化に伴ってフロート状の浮上部２７ａが浮き沈みし、水位が下がることで開閉弁２７が分岐吸水管２５を閉鎖するようになっていることから、送水用ポンプが斜めに傾いた場合には、開閉弁２７によって分岐吸水管２５を閉鎖できない場合も生じていた。この場合、空気の進入によってサイホン作用が働かず、再度水中ポンプを駆動させなければならないという煩雑さがあった。また、図１３に示すフロート状の浮上部２７ａは、軟質ゴムなどのフレキシブルな素材から成る袋状物であるため、吸水時に分岐吸水管２５の中まで吸い込まれてしまうことがある。この場合、水位が上昇しても、その部分が分岐吸水管２５内に吸着されて浮上部２７ａが浮上できないため、分岐吸水管２５が開放されず、サイホン作用を利用した送水が再開できない事態に至るおそれがあった。   However, in the case of the on-off valve 27, the float-like floating portion 27a rises and falls with the change of the upstream water level, and the on-off valve 27 closes the branch water intake pipe 25 by lowering the water level. Therefore, when the water supply pump is inclined obliquely, the branch water intake pipe 25 cannot be closed by the on-off valve 27. In this case, the siphon action does not work due to the entry of air, and the submersible pump must be driven again. Further, since the float-like floating portion 27a shown in FIG. 13 is a bag-like material made of a flexible material such as soft rubber, the float-like floating portion 27a may be sucked into the branched water absorption pipe 25 at the time of water absorption. In this case, even if the water level rises, the portion is adsorbed in the branch water absorption pipe 25 and the floating part 27a cannot rise, so the branch water absorption pipe 25 is not opened and water supply using siphon action cannot be resumed. There was a risk.

本発明は、上記送水用ポンプの開閉弁をさらに改良したものであり、送水用ポンプが斜めに傾いた場合であっても、分岐吸水管を閉鎖して、空気の進入を確実に阻止することができ、しかも水位が上昇したときには、サイホン作用を利用した送液が確実に再開されるようにした開閉装置、並びにその開閉装置を使用した液体の送液方法を提供することを目的とするものである。   The present invention further improves the opening / closing valve of the water supply pump, and even when the water supply pump is inclined obliquely, the branch water intake pipe is closed to reliably prevent air from entering. It is possible to provide a switchgear that can reliably resume liquid feeding using siphon action when the water level rises, and a liquid feeding method using the switchgear It is.

上記目的を達成するため、本発明は、障害物の両側に誇設された送液管を通じて、前記障害物の一方の側に溜まった液体をサイホン作用を利用して他方側へ移動させる送液用ポンプに直接的又は間接的に接続される開閉装置であって、
前記送液管に繋がる通液路を構成する装置本体と、前記装置本体内において回動又は摺動することで前記通液路を開閉する開閉弁と、前記障害物の一方の側に溜った水面位置の変動に連動して前記開閉弁を開閉動させる連動部材とを備えたことを特徴とする開閉装置をその要旨とした。 In order to achieve the above-mentioned object, the present invention provides a liquid feeding method in which liquid accumulated on one side of the obstacle is moved to the other side using a siphon action through liquid feeding pipes provided on both sides of the obstacle. A switchgear connected directly or indirectly to the pump for use,
An apparatus main body constituting a liquid passage connected to the liquid supply pipe, an on-off valve that opens and closes the liquid passage by rotating or sliding in the apparatus main body, and accumulated on one side of the obstacle The gist of the present invention is an opening / closing device comprising an interlocking member that opens and closes the opening / closing valve in conjunction with a change in the water surface position.

本発明の開閉装置において、障害物の一方の側に溜った水面位置の変動に連動して開閉弁を開閉動させる連動部材としては、例えば図１〜図６に示すように、障害物の一方の側に溜った水面上に配されるフロートと、障害物の一方の側に溜った水面位置の変動に伴うフロートの位置変化に従って引張弛緩される連結部材と、前記連結部材の引張弛緩に伴って装置本体の通液路内に設けた回動軸周りに回動する開閉コックとからなるものを挙げることができる。   In the opening / closing apparatus of the present invention, as an interlocking member that opens and closes the opening / closing valve in conjunction with the fluctuation of the water surface position accumulated on one side of the obstacle, for example, as shown in FIGS. A float disposed on the surface of the water accumulated on the side of the obstacle, a connecting member that is tension-relaxed according to a change in the position of the float accompanying a change in the position of the water surface accumulated on one side of the obstacle, And an opening / closing cock that rotates around a rotation shaft provided in the liquid passage of the apparatus main body.

このような連動部材を採用した場合、障害物の一方の側に溜った水面位置の変動に伴う前記フロートの位置変化に従って連結部材が引張弛緩され、これに伴って前記開閉コックが回動軸周りに回動することで同軸に軸支された開閉弁が回動し、装置本体の通液路を開閉するようになる。   When such an interlocking member is adopted, the connecting member is pulled and loosened according to the position change of the float accompanying the fluctuation of the water surface position accumulated on one side of the obstacle, and accordingly the opening / closing cock is rotated around the rotation axis. , The on-off valve pivotally supported by the shaft rotates to open and close the liquid passage of the apparatus main body.

また別の連動部材としては、例えば図７に示すように、障害物の一方の側に溜った水面位置の変動を検知する水位センサーと、前記水位センサーからの信号を受けて開閉弁を開閉動させる駆動部とからなるものを挙げることができる。   As another interlocking member, for example, as shown in FIG. 7, a water level sensor that detects a change in the water surface position accumulated on one side of the obstacle, and an open / close valve that opens and closes in response to a signal from the water level sensor. The thing which consists of a drive part to be made can be mentioned.

このような連動部材を採用した場合、障害物の一方の側に溜った水面位置の変動を検知した水位センサーからの信号を受けて駆動部が駆動して開閉弁を回動軸周りに回動させて装置本体の通液路を開閉するようになる。   When such an interlocking member is adopted, the drive unit is driven by the signal from the water level sensor that detects the change in the water surface position accumulated on one side of the obstacle, and the on-off valve rotates about the rotation axis. As a result, the liquid passage of the apparatus main body is opened and closed.

また別の連動部材としては、例えば図８に示すように、障害物の一方の側に溜った水面上に配されるフロートと、フロート上面に立設固定され、障害物の一方の側に溜った水面位置の変動に伴うフロートの位置変化に従って昇降動する連結杆とからなるものを挙げることができる。   As another interlocking member, for example, as shown in FIG. 8, a float arranged on the water surface collected on one side of the obstacle, and standing and fixed on the upper surface of the float, collected on one side of the obstacle. And a connecting rod that moves up and down according to a change in the position of the float accompanying a change in the water surface position.

このような連動部材を採用した場合、障害物の一方の側に溜った水面位置の変動に伴う前記フロートの位置変化に従って連結杆が昇降動し、これに伴って開閉弁が摺動して装置本体の通液路を開閉するようになる。   When such an interlocking member is adopted, the connecting rod moves up and down according to the position change of the float accompanying the change of the water surface position accumulated on one side of the obstacle, and the on-off valve slides along with this, and the device slides. It opens and closes the fluid passage of the main body.

さらに別の連動部材としては、例えば図９に示すように、障害物の一方の側に溜った水面位置の変動を検知する水位センサーと、前記水位センサーからの信号を受けて開閉弁を摺動させる駆動部とからなるものを挙げることができる。   As another interlocking member, for example, as shown in FIG. 9, a water level sensor that detects a change in the water surface position accumulated on one side of the obstacle, and a sliding valve that receives a signal from the water level sensor. The thing which consists of a drive part to be made can be mentioned.

このような連動部材を採用した場合、障害物の一方の側に溜った水面位置の変動を検知した水位センサーからの信号を受けて駆動部が駆動して開閉弁を摺動させて装置本体の通液路を開閉するようになる。   When such an interlocking member is adopted, the drive unit is driven in response to a signal from the water level sensor that detects the change in the water surface position accumulated on one side of the obstacle, and the on-off valve is slid to drive the device body. The liquid passage is opened and closed.

本発明の開閉装置は、障害物の両側に誇設された送液管を通じて、前記障害物の一方の側に溜まった液体をサイホン作用を利用して他方側へ移動させる送液用ポンプに直接的又は間接的に接続されるものであり、該開閉装置によれば、送液管に繋がる通液路を構成する装置本体内に設けた開閉弁が、障害物の一方の側に溜った水面位置の変動に連動する連動部材によって装置本体内において回動又は摺動することで前記通液路を開閉するようになっていることから、送液用ポンプが斜めに傾いた場合であっても、水位が下がった場合には装置本体内の開閉弁が閉動して該装置本体の通液路を閉鎖するので、空気の進入を確実に阻止することができ、しかも水位が上昇したときには、サイホン作用を利用した送液が確実に再開される。   The switchgear according to the present invention is directly connected to a liquid feed pump for moving the liquid accumulated on one side of the obstacle to the other side using a siphon action through the liquid feed pipes provided on both sides of the obstacle. According to the opening / closing device, the opening / closing valve provided in the device main body constituting the fluid passage connected to the liquid feeding pipe is a water surface collected on one side of the obstacle. Since the liquid passage is opened and closed by rotating or sliding in the apparatus main body by an interlocking member that interlocks with a change in position, even if the liquid feeding pump is inclined obliquely When the water level drops, the on-off valve in the device main body closes and closes the liquid passage of the device main body, so that the ingress of air can be reliably prevented, and when the water level rises, The liquid delivery using the siphon action is reliably resumed.

以下、本発明の開閉装置、並びにその開閉装置を使用した液体の送液方法を図面に示した一実施の形態に従った詳細に説明する。尚、本発明の液体の送液方法は、本発明の開閉装置を説明する中で説明する。本発明は送液用ポンプに接続される開閉装置に関するものであり、図１には、この開閉装置を接続した送液用ポンプを河川の橋脚や堰堤の建設に行われる締切り工事に適用した具体例を示した。図１において、河川の締切部４１の上流側には流下した水を貯留する上流側貯留部４２が設けられ、締切部４１の下流側には、前記上流側貯留部４２の水位よりも低い位置に下流側貯留部４３が設けられている。   Hereinafter, the switchgear of the present invention and a liquid feeding method using the switchgear will be described in detail according to the embodiment shown in the drawings. The liquid feeding method of the present invention will be described in the description of the switchgear of the present invention. The present invention relates to a switchgear connected to a pump for feeding liquid. FIG. 1 shows a concrete example in which the pump for feeding liquid connected to this switchgear is applied to a closing work performed for construction of a river pier or a dam. An example is shown. In FIG. 1, an upstream storage portion 42 that stores water that has flowed down is provided upstream of the river cut-off portion 41, and a position lower than the water level of the upstream storage portion 42 is provided downstream of the cut-off portion 41. The downstream storage part 43 is provided in this.

河川を締め切る締切部４１を跨ぐように送液管４４が配置され、この送液管４４の一端４４ａが上流側貯留部４２に配され、他端４４ｂが下流側貯留部４３に配されている。この送液管４１の上流側貯留部４２に配される一端４４ａ側に送液用ポンプ５０が接続されている。   A liquid supply pipe 44 is disposed so as to straddle the cut-off part 41 that closes the river. One end 44 a of the liquid supply pipe 44 is arranged in the upstream storage part 42, and the other end 44 b is arranged in the downstream storage part 43. . A liquid feed pump 50 is connected to the one end 44 a disposed in the upstream side storage section 42 of the liquid feed pipe 41.

送液用ポンプ５０は、サイホン作用を利用して送液するものであり、水中ポンプ５１と分岐吸液管５２とからなる。水中ポンプ５１は従来周知のものであり、その吐出側５１ａが本発明の開閉装置６０の装置本体６１下端に接続されており、電力線またはエンジン発動機からの電力によって駆動するようになっている。   The liquid-feeding pump 50 feeds liquid using a siphon action, and includes an underwater pump 51 and a branch liquid absorption pipe 52. The submersible pump 51 is well known in the art, and its discharge side 51a is connected to the lower end of the device body 61 of the opening / closing device 60 of the present invention, and is driven by the power from the power line or the engine engine.

分岐吸液管５２は、前記水中ポンプ５１の吐出側部分５１ａに開口し、この部分５１ａから略直角に分岐され、前記水中ポンプ５１と共に上流側貯留部４２の水面下に浸漬されている。この分岐吸液管５２の水中ポンプ５１の吐出側部分５１ａに形成された開口５２ａには、開閉蓋５２ｂが回動可能に軸支されている。
この開閉蓋５２ｂは、前記水中ポンプ５１が駆動しているときは、吐出側部分５１ａへの開口５２ａを閉鎖し、水中ポンプ５１が停止したときは、吐出側部分５１ａへの開口５２ａを開放するように動作するようになっている。またこの開閉蓋５２ｂは、水中ポンプ５１の駆動中、水中ポンプ５１によって吸い上げられた液体が分岐吸液管５２側へ逆流するのを防止する働きがあり、開口５２ａ周辺での渦の発生を防ぎ、送液効率をより高める効果を奏する。 The branch liquid absorption pipe 52 opens to the discharge side portion 51 a of the submersible pump 51, branches from the portion 51 a at a substantially right angle, and is immersed under the water surface of the upstream storage portion 42 together with the submersible pump 51. An opening / closing lid 52b is pivotally supported by an opening 52a formed in the discharge side portion 51a of the submersible pump 51 of the branch liquid absorption pipe 52.
The open / close lid 52b closes the opening 52a to the discharge side portion 51a when the submersible pump 51 is driven, and opens the opening 52a to the discharge side portion 51a when the submersible pump 51 stops. Is supposed to work. The open / close lid 52b functions to prevent the liquid sucked up by the submersible pump 51 from flowing back to the branch suction pipe 52 side during the operation of the submersible pump 51, thereby preventing the generation of vortex around the opening 52a. The effect of further increasing the liquid feeding efficiency is achieved.

上記の如く構成された送液用ポンプ５０にあっては、上流側貯留部４２の水位上昇に伴って水中ポンプ５１を駆動させる。水中ポンプ５１下部の吸入口５１ｂから吸い込まれた液体は、図１中矢印Ａに示すように、吐出側部分５１ａからこれに繋がる開閉装置６０を経由して送液管４４の一端４４ａから送液管４４を通り、送液管４４の他端４４ｂから下流側貯留部４３へと送液される。   In the liquid feed pump 50 configured as described above, the submersible pump 51 is driven as the water level rises in the upstream storage section 42. As shown by an arrow A in FIG. 1, the liquid sucked from the suction port 51b at the bottom of the submersible pump 51 is fed from one end 44a of the liquid feed pipe 44 through the opening / closing device 60 connected to the discharge side part 51a. The liquid is fed from the other end 44 b of the liquid feeding pipe 44 to the downstream storage section 43 through the pipe 44.

上記送液が定常状態となり、送液管４４内が満水状態となったとき、水中ポンプ５１を停止させる。するとサイホン作用の働きによって、開閉蓋５２ｂが開いて吐出側部分５１ａへの開口５２ａが開放し、引き続き図１中矢印Ｂに示すように、分岐吸液管５２下部に設けた吸入口５２ｃから上流側貯留部４２内の液体が吸い込まれ、吐出側部分５１ａ、これに繋がる開閉装置６０を経由して送液管４４の一端４４ａから送液管４４を通り、送液管４４の他端４４ｂから下流側貯留部４３へと送液されるようになる。   When the liquid feeding is in a steady state and the liquid feeding pipe 44 is full, the submersible pump 51 is stopped. Then, due to the action of the siphon action, the opening / closing lid 52b is opened and the opening 52a to the discharge side portion 51a is opened. Subsequently, as shown by the arrow B in FIG. 1, upstream from the suction port 52c provided at the lower part of the branch suction pipe 52 The liquid in the side reservoir 42 is sucked in, passes through the discharge side portion 51a, the opening / closing device 60 connected thereto, the liquid supply pipe 44 from one end 44a through the liquid supply pipe 44, and from the other end 44b of the liquid supply pipe 44. Liquid is fed to the downstream storage section 43.

上記送液用ポンプ５０によるサイホン作用を利用した送液は、上流側貯留部４２内の水位が所定高さまで低下すると、開閉装置６０の働きにより送液管４４への流路が閉鎖され、送液が停止される。上流側貯留部４２内の水位が所定高さまで回復したとき、開閉装置６０の働きにより送液管４４への流路が開放され、再びサイホン作用を利用した送液が再開される。次に、このような作用効果を奏する開閉装置６０について詳説する。尚、本発明の開閉装置を接続した送液用ポンプは、河川の橋脚や堰堤の建設工事などの他に、水処理場の水処理設備、工場の排水処理設備や廃油処理設備における汚水や廃液の処理、廃油の処理の際の送液にも利用することができる。尚、本発明の開閉装置が直接的又は間接的に接続される送液用ポンプには、上述したものの他、従来公知の水中ポンプを利用することもできる。   When the water level in the upstream reservoir 42 is lowered to a predetermined height, the liquid supply utilizing the siphon action by the liquid supply pump 50 is closed by the action of the opening / closing device 60 to close the flow path to the liquid supply pipe 44. The liquid is stopped. When the water level in the upstream reservoir 42 is restored to a predetermined height, the flow path to the liquid feeding pipe 44 is opened by the action of the opening / closing device 60, and liquid feeding using the siphon action is resumed. Next, the opening / closing device 60 having such an effect will be described in detail. In addition to the construction work of river piers and dams, etc., the pump for feeding liquid connected to the switchgear according to the present invention is used for sewage and wastewater in water treatment facilities in water treatment plants, wastewater treatment facilities and waste oil treatment facilities in factories. It can also be used for liquid feeding during the treatment of waste oil and waste oil. In addition, what is mentioned above can also utilize a conventionally well-known submersible pump for the pump for liquid feeding to which the switchgear of this invention is connected directly or indirectly.

本発明の開閉装置は、送液管に繋がる通水路を構成する装置本体と、装置本体装置本体内において回動又は摺動することで前記通液路を開閉する開閉弁と、障害物の一方の側に溜った水面位置の変動に連動して前記開閉弁を開閉動させる連動部材とを備えたことで特徴付けられたものであり、障害物の一方の側に溜った水面位置が変動したとき、これに連動して装置本体の通液路内の開閉弁を開閉させる連動部材には、様々な形態のものを採用することができる。まず、図１〜図６に示す連動部材を採用した開閉装置６０について説明する。   The opening / closing device of the present invention includes an apparatus main body constituting a water passage connected to a liquid feed pipe, an on-off valve that opens or closes the liquid passage by rotating or sliding in the apparatus main body, and one of obstacles. It is characterized by having an interlocking member that opens and closes the on-off valve in conjunction with the fluctuation of the water surface position accumulated on the side of the water, and the water surface position accumulated on one side of the obstacle fluctuated Sometimes, various forms of interlocking members that open and close the on-off valve in the liquid passage of the apparatus main body can be employed in conjunction with this. First, the opening / closing device 60 employing the interlocking member shown in FIGS. 1 to 6 will be described.

図１〜図６に示す開閉装置６０は、送液用ポンプ５０に直接的に接続される形態を示すものであり、装置本体６１と、前記装置本体６１の通液路６１ａ内に設けた回動軸６２に軸支される開閉弁６３と、障害物である締切部４１の一方の側に溜った水面位置の変動に連動して前記開閉弁６３を回動させて通液路６１ａを開閉させる連動部材６６とを備えたことを特徴とするものである。   The opening / closing device 60 shown in FIG. 1 to FIG. 6 shows a configuration in which the opening / closing device 60 is directly connected to the liquid feed pump 50. The on-off valve 63 pivotally supported by the moving shaft 62 and the on-off valve 63 are rotated in conjunction with the fluctuation of the water surface position accumulated on one side of the shut-off portion 41 which is an obstacle to open and close the liquid passage 61a. The interlocking member 66 to be provided is provided.

この開閉装置６０において、装置本体６１は円筒状をなしており、送液用ポンプ５０と前記送液管４４とを繋ぐ通水路６１ａを構成するようになっている。この装置本体６１の通液路６１ａ内には、液体の通過方向と直交する方向に回動軸６２が横設されており、この回動軸６２に通液路６１ａを開閉する開閉弁６３が回動可能に軸支されている。開閉弁６３は、装置本体６１の通液路６１ａを閉蓋することができるように、通液路６１ａの断面形状に対応する大きさの円盤状に設けられている。尚、開閉弁６３は、装置本体６１の通液路６１ａ内で回動し、かつこの通液路６１ａを閉塞可能なものであるならば、その形状や大きさは特に限定されない。   In the opening / closing device 60, the device main body 61 has a cylindrical shape and constitutes a water passage 61 a that connects the liquid feeding pump 50 and the liquid feeding pipe 44. In the liquid passage 61a of the apparatus main body 61, a rotating shaft 62 is provided in a direction orthogonal to the liquid passing direction, and an opening / closing valve 63 for opening and closing the liquid passage 61a on the rotating shaft 62 is provided. It is pivotally supported so that it can rotate. The on-off valve 63 is provided in a disc shape having a size corresponding to the cross-sectional shape of the liquid passage 61 a so that the liquid passage 61 a of the apparatus main body 61 can be closed. The on-off valve 63 is not particularly limited in its shape and size as long as it rotates within the liquid passage 61a of the apparatus main body 61 and can close the liquid passage 61a.

開閉弁６３の回動軸６２と直交する方向（液体の通過方向）の一方端部表面には液流を受ける羽根部材６４が設けられている。羽根部材６４は、開閉弁６３の両表面から飛び出た状態に設けられているため、開閉弁６３が開状態にあり、装置本体６１の通液路６１ａ内を液体が通過しているとき、開閉弁６３の両表面から飛び出た羽根部材６４がその液流を受けて開閉弁６３を開状態に保持するようになっている。   A blade member 64 that receives a liquid flow is provided on one end surface of the opening / closing valve 63 in a direction orthogonal to the rotation shaft 62 (liquid passing direction). Since the blade member 64 is provided so as to protrude from both surfaces of the opening / closing valve 63, the opening / closing valve 63 is opened and closed when the opening / closing valve 63 is open and liquid is passing through the liquid passage 61a of the apparatus main body 61. The blade member 64 jumping out from both surfaces of the valve 63 receives the liquid flow and holds the on-off valve 63 in an open state.

また装置本体６１の通液路６１ａ内には、前記開閉弁６３の回動する両端部が当接するストッパー６５が前記開閉弁６３を軸支する回動軸６２とほぼ同じ高さ位置にそれぞれ設けられており、開閉弁６３が通液路６１ａを閉塞した状態を保持するように、その回動範囲が規制されるようになっている。   Further, in the liquid passage 61 a of the apparatus main body 61, stoppers 65 with which both ends of the opening / closing valve 63 abut are provided at substantially the same height as the rotating shaft 62 that pivotally supports the opening / closing valve 63. Therefore, the range of rotation is restricted so that the on-off valve 63 maintains the closed state of the liquid passage 61a.

次に、障害物である締切部の一方の側に溜った水面位置の変動に連動して上記開閉弁を開閉動させる連動部材について説明する。図１〜図６に示す連動部材６６は、障害物（締切部４１）の一方の側に溜った水面上に配されるフロート６７と、障害物（締切部４１）の一方の側に溜った水面位置の変動に伴うフロート６７の位置変化に従って引張弛緩される連結部材６８と、前記連結部材の引張弛緩に伴って装置本体６１の通液路６１ａ内に設けた回動軸６２周りに回動する開閉コック６９とからなる。   Next, a description will be given of an interlocking member that opens and closes the on-off valve in conjunction with fluctuations in the water surface position accumulated on one side of the shut-off portion that is an obstacle. The interlocking member 66 shown in FIGS. 1 to 6 is floated on the water surface collected on one side of the obstacle (the cut-off part 41) and collected on one side of the obstacle (the cut-off part 41). A connecting member 68 that is pulled or loosened in accordance with a change in the position of the float 67 that accompanies a change in the water surface position, and rotates around a rotating shaft 62 that is provided in the liquid passage 61a of the apparatus main body 61 as the connecting member is pulled or loosened. And an open / close cock 69.

フロート６７は、上流側貯留部４２に浮かべて、その水位に従って昇降動するものであれば何でも良く、例えば木、発泡樹脂ブロック、風船などを挙げることができる。このフロート６７に接続される連結部材６８はワイヤーなどからなり、その太さや長さは任意である。この連結部材６８の先端は、装置本体６１に設けたリング状の誘導金具７０を経由して装置本体６１の回動軸６２に一方端が軸支された開閉コック６９の他方端に繋がっている。図示の開閉コック６９は棒状をなす重りであり、その自重によって前記連結部材６８を弛緩方向に付勢するようになっている。   The float 67 may be anything that floats on the upstream storage section 42 and moves up and down according to the water level. Examples thereof include wood, foamed resin blocks, and balloons. The connecting member 68 connected to the float 67 is made of a wire or the like, and its thickness and length are arbitrary. The distal end of the connecting member 68 is connected to the other end of an opening / closing cock 69 whose one end is pivotally supported on the rotation shaft 62 of the apparatus main body 61 via a ring-shaped guide fitting 70 provided on the apparatus main body 61. . The illustrated opening / closing cock 69 is a rod-shaped weight that urges the connecting member 68 in the relaxation direction by its own weight.

この開閉装置６０によれば、障害物（締切部４１）の一方の側に溜った水面位置が低下したとき、これに伴ってフロート６７の位置が下降すると、これに従って連結部材６８が引張されることになる。連結部材６８が引張されるのに伴って開閉コック６９が回動軸６２周りに回動し、同軸に軸支された開閉弁６３が回動し、その開閉弁６３の回動端部が装置本体６１の通液路６１ａ内に設けたストッパー６５に当接し、該通液路６１ａを閉塞状態に保持する。   According to the opening / closing device 60, when the position of the water surface accumulated on one side of the obstacle (the cut-off portion 41) is lowered, the position of the float 67 is lowered accordingly, and the connecting member 68 is pulled accordingly. It will be. As the connecting member 68 is pulled, the opening / closing cock 69 rotates around the rotation shaft 62, the coaxially supported opening / closing valve 63 rotates, and the rotation end of the opening / closing valve 63 is the device. Abutting against a stopper 65 provided in the liquid passage 61a of the main body 61, the liquid passage 61a is kept closed.

一方、障害物（締切部４１）の一方の側に溜った水面位置が上がり、これに伴ってフロート６７の位置が上昇すると、これに従って連結部材６８が弛緩されることになる。連結部材６８が弛緩されると、開閉コック６９がその自重と液体の流れに押されて回動軸６２周りに弛緩方向に回動する。回動軸６２の回動に伴って同軸に軸支された開閉弁６３が回動し、該通液路６１ａを開放する。通液路６１ａの開放により、再びサイホン作用によって送液が開始される。送液が開始されると、開閉弁６３の両表面から飛び出た羽根部材６４がその液流を受けて開閉弁６３を開状態に保持するようになっている。   On the other hand, when the position of the water surface accumulated on one side of the obstacle (the cut-off portion 41) rises and the position of the float 67 rises accordingly, the connecting member 68 is loosened accordingly. When the connecting member 68 is relaxed, the open / close cock 69 is pushed by its own weight and the flow of liquid, and rotates around the rotation shaft 62 in the relaxation direction. Along with the rotation of the rotation shaft 62, the on-off valve 63 pivotally supported by the rotation rotates to open the liquid passage 61a. With the opening of the liquid passage 61a, liquid feeding is started again by the siphon action. When the liquid feeding is started, the blade member 64 jumping out from both surfaces of the on-off valve 63 receives the liquid flow and holds the on-off valve 63 in the open state.

次に、図７の開閉装置８０について説明する。図７に示す開閉装置８０は、図１〜図６に示すものと同じく、送液用ポンプ５０に直接的に接続される形態を示すものであり、連動部材８１が、障害物の一方の側に溜った水面位置の変動を検知する水位センサー８２と、前記水位センサー８２からの信号を受けて開閉弁６３を開閉動させる駆動部８３とからなるものである。   Next, the opening / closing device 80 of FIG. 7 will be described. The open / close device 80 shown in FIG. 7 is similar to that shown in FIGS. 1 to 6 and is configured to be directly connected to the liquid feed pump 50, and the interlocking member 81 is on one side of the obstacle The water level sensor 82 detects a change in the water surface position accumulated in the water level, and a drive unit 83 that opens and closes the on-off valve 63 in response to a signal from the water level sensor 82.

水位センサー８２は、従来公知の赤外線を用いた水位計など、水位を測定できるものならば何でもよい。また水位センサー８２には、該水位センサー８２によって測定された水位情報を信号化して駆動部８３へと発信する発信部８２ａを有しており、水位センサー８２によって得られた水位情報が駆動部８３へと発信されるようになっている。一方、駆動部８３は、水位センサー８２からの信号を受け取る受信部８３ａと、水位センサー８２から受け取った水位情報に従って、その水位が予め設定された２つの設定水位、すなわち装置本体６１の通液路６１ａを閉塞させるべき下限水位を下回るか否か、或いは通液路６１ａを開放すべき上限水位を上回るか否かを判断する制御部８３ｂと、開閉弁６３を軸支する回動軸６２を回転させて駆動モータ８３ｃとからなり、水位センサー８２から受け取った水位情報に従って、制御部８３ｂが下限水位を下回ると判断した場合には、駆動モータ８３ｃを駆動させて回動軸６２を回転させ、同軸に軸支される開閉弁６３を通液路６１ａが閉塞されるように回動させる。一方、制御部８３ｂが上限水位を上回ると判断した場合には、駆動モータ８３ｃを駆動させて回動軸６２を回転させて開閉弁６３を通液路６１ａが開放されるように回動させる。   The water level sensor 82 may be anything that can measure the water level, such as a conventionally known water level gauge using infrared rays. Further, the water level sensor 82 has a transmitter 82a that converts the water level information measured by the water level sensor 82 into a signal and transmits the signal to the drive unit 83. The water level information obtained by the water level sensor 82 is the drive unit 83. To be sent to. On the other hand, the drive unit 83 includes a receiving unit 83a that receives a signal from the water level sensor 82, and two set water levels whose water levels are set in advance according to the water level information received from the water level sensor 82, that is, the liquid passage of the device main body 61 The controller 83b that determines whether or not the lower limit water level that should close the 61a or the upper limit water level that should open the liquid passage 61a and the rotary shaft 62 that pivotally supports the on-off valve 63 are rotated. When the control unit 83b determines that the lower water level is lower than the lower limit water level according to the water level information received from the water level sensor 82, the drive motor 83c is driven to rotate the rotating shaft 62 and coaxially. The on-off valve 63 that is pivotally supported is rotated so that the liquid passage 61a is closed. On the other hand, when the control unit 83b determines that the upper limit water level is exceeded, the drive motor 83c is driven to rotate the rotation shaft 62 and rotate the opening / closing valve 63 so that the liquid passage 61a is opened.

尚、水位センサー、発信部、駆動部を構成する受信部、制御部、及び駆動モータとしては特に限定されず、送液ポンプ及び送液管の容量、大きさ（太さ）、使用状況、用途、送液ポンプ及び送液管を流れる液量などを考慮して適宜決定すればよい。   It should be noted that the water level sensor, the transmitter, the receiver that constitutes the drive unit, the control unit, and the drive motor are not particularly limited. The amount may be appropriately determined in consideration of the amount of liquid flowing through the liquid feeding pump and the liquid feeding pipe.

次に、本発明の開閉装置の別の形態を説明する。図８に示す開閉装置１００は、送液用ポンプ１０２に直接接続されず、送液用ポンプ１０２に接続される送液管１０１の端部近傍に接続される形態を示すものであり、内部に通液路を構成する箱形状の装置本体１０３と、前記装置本体１０１内を摺動して通液路を連通させる開放窓１０４ａを下部に有する板状の開閉弁１０４と、障害物の一方の側に溜った水面位置の変動に連動して前記開閉弁１０４を摺動させる連動部材１０５とを備えたものである。   Next, another embodiment of the switchgear according to the present invention will be described. The opening / closing device 100 shown in FIG. 8 is not directly connected to the liquid delivery pump 102 but is connected to the vicinity of the end of the liquid delivery pipe 101 connected to the liquid delivery pump 102. A box-shaped device main body 103 constituting the liquid passage, a plate-like on-off valve 104 having an open window 104a in the lower portion that slides in the device main body 101 to communicate with the liquid passage, and one of the obstacles And an interlocking member 105 that slides the on-off valve 104 in conjunction with the fluctuation of the water surface position accumulated on the side.

また図８に示す連動部材１０５は、障害物の一方の側に溜った水面上に配されるフロート１０６と、フロート１０６上面に立設固定され、障害物の一方の側に溜った水面位置の変動に伴うフロート１０６の位置変化に従って昇降動する連結杆１０７からなる。   Further, the interlocking member 105 shown in FIG. 8 has a float 106 disposed on the water surface accumulated on one side of the obstacle, and is fixed upright on the upper surface of the float 106, and has a position of the water surface accumulated on one side of the obstacle. It consists of a connecting rod 107 that moves up and down in accordance with a change in the position of the float 106 that accompanies the fluctuation.

連結杆１０７は、開閉弁１０４下部にその端部が取り付けられており、フロート１０６が水面位置の変動に伴って位置変化するのに従って昇降動するようになっている。このため、例えば水位が低下すると、フロート１０６が下方に位置を変え、これに伴ってフロート１０６上面に立設固定された連結杆１０７が下降し、これにより、該連結杆１０７に繋がる開閉弁１０４が装置本体１０３内を下動して該装置本体１０３の通液路が閉塞されることになる。   The end of the connecting rod 107 is attached to the lower part of the on-off valve 104 so that the float 106 moves up and down as the position of the float 106 changes as the water surface position changes. For this reason, for example, when the water level is lowered, the float 106 changes its position downward, and accordingly, the connecting rod 107 erected and fixed on the upper surface of the float 106 is lowered, thereby the on-off valve 104 connected to the connecting rod 107. Moves down in the apparatus main body 103 and the liquid passage of the apparatus main body 103 is closed.

一方、水位が上昇すると、フロート１０６が上方に位置を変え、これに伴ってフロート１０６上面に立設固定された連結杆１０７が上降することになる。これにより、該連結杆１０７に繋がる開閉弁１０４が装置本体１０３内を上動して該装置本体１０３の通液路の位置に開閉弁１０４の開放窓１０４ａが位置するようにすることで前記通液路を連通させ、通液が再開されるようになっている。   On the other hand, when the water level rises, the float 106 changes its position upward, and accordingly, the connecting rod 107 standing and fixed on the upper surface of the float 106 descends. As a result, the on-off valve 104 connected to the connecting rod 107 moves up in the apparatus main body 103 so that the open window 104a of the on-off valve 104 is positioned at the position of the liquid passage of the apparatus main body 103. The liquid passage is communicated and the liquid flow is resumed.

尚、図示はしないが、装置本体１０３内には開閉弁１０４の上端が当接するストッパーが設けられており、開閉弁１０４が上動したとき、その開放窓１０４ａが通液路に位置するように、上動位置を規制するようになっている。   Although not shown, the apparatus main body 103 is provided with a stopper with which the upper end of the on-off valve 104 abuts so that when the on-off valve 104 moves up, its open window 104a is positioned in the liquid passage. The upper moving position is regulated.

図９は、連動部材１１１が、障害物の一方の側に溜った水面位置の変動を検知する水位センサー１１２と、開閉弁１０４を上下動させる駆動部１１３とからなる形態を示している。この形態における水位センサー１１２は、図８に示すものと同じであるため、ここでの説明は割愛する。   FIG. 9 shows a form in which the interlocking member 111 includes a water level sensor 112 that detects a change in the water surface position accumulated on one side of the obstacle, and a drive unit 113 that moves the on-off valve 104 up and down. Since the water level sensor 112 in this embodiment is the same as that shown in FIG. 8, description thereof is omitted here.

駆動部１１３は、装置本体１０３に付設されており、水位センサー１１２からの信号を受け取る受信部１１３ａと、水位センサー１１２から受け取った水位情報に従って、その水位が予め設定された２つの設定水位、すなわち装置本体１０３の通液路を閉塞させるべき下限水位を下回るか否か、或いは通液路を開放すべき上限水位を上回るか否かを判断する制御部１１３ｂと、前記開閉弁１０４を上下動させるシリンダー１１３ｃとからなり、水位センサー１１２から受け取った水位情報に従って、制御部１１３ｂが下限水位を下回ると判断した場合には、シリンダー１１３ｃを駆動させて開閉弁１０４を装置本体１０３内で下動させて、通液路が閉塞させる。   The drive unit 113 is attached to the apparatus main body 103 and receives two set water levels whose water levels are set in advance according to the water level information received from the receiving unit 113a that receives a signal from the water level sensor 112 and the water level sensor 112, that is, The controller 113b for determining whether or not the lower limit water level at which the liquid passage of the apparatus main body 103 should be blocked or below the upper limit water level at which the liquid passage should be opened and the on-off valve 104 are moved up and down. When the control unit 113b determines that the lower limit water level is lower than the lower limit water level according to the water level information received from the water level sensor 112, the cylinder 113c is driven to move the on-off valve 104 downward in the apparatus main body 103. The fluid passage is blocked.

一方、制御部１１３ｂが上限水位を上回ると判断した場合には、シリンダー１１３ｃを駆動させて開閉弁１０４を装置本体１０３内で上動させ、該装置本体１０３の通液路の位置に開閉弁１０４の開放窓１０４ａが位置するようにすることで前記通液路を連通させ、通液が再開されるようになっている。   On the other hand, when the control unit 113b determines that the upper limit water level is exceeded, the cylinder 113c is driven to move the on-off valve 104 up in the apparatus main body 103, and the on-off valve 104 is moved to the position of the liquid passage in the apparatus main body 103. The open window 104a is positioned so that the liquid passage is communicated and the liquid passage is resumed.
