をしたり、取水管の管理を厳密に行う必要がある。By the way, in the above-mentioned conventional method, since the pump in the former method is installed underwater, it is easily damaged by water and it is difficult to perform maintenance and troubleshooting easily. In addition, the latter type of pump is installed on land, so the problems of the former mentioned above are avoided, but since it is a suction type, there is a problem that water cannot be sucked in due to air intrusion, and when the pump is activated. It is necessary to properly manage the intake pipes.

能となる。As a result, in the present invention, the pump can be installed on land and can be easily managed, and problems caused by air intrusion can be avoided by using a discharge type submersible pump.
以下、本発明の実施例の一つを図面に基づいて説明する
。Hereinafter, one embodiment of the present invention will be described based on the drawings.
図面において、符号１は陸地、２は海であり、海２の水
面２ａの下に浮遊式取水口装置３がアンカー４に鎖５で
結んで設置されている。In the drawings, reference numeral 1 indicates land and 2 indicates the sea, and a floating water intake device 3 is installed below the water surface 2a of the sea 2 by being connected to an anchor 4 with a chain 5.

プ１１のモータ１２にケーブルＩ７が接続され、水中ポ
ンプ１１の吐出口１５からの導管１８がキャップ９を介
して、ポンプ室７の外に導出されている。Therefore, a hole 6, for example, is dug deeper than the water surface in the land 1, and a pump chamber 7 is installed inside this hole 6. The pump chamber 7 has an airtight structure in which a cap 9 is airtightly attached to a cylindrical case 8, and the lower part of the case 8 communicates with the water intake device 3 via a water intake pipe 10 and is placed at the same height as the water surface 2a. Water is introduced into the case 8, and a submersible pump 11 is vertically housed inside the case 8. The submersible pump 11 includes a motor 12, a pump body 13, an inlet 14, and an outlet 15.
The intake port 14 is submerged in water. Further, a partition wall 16 for separating air bubbles is vertically attached to the inside of the pump chamber 7 on the side communicating with the water intake pipe 10, and a strainer, a sand separator, etc. are attached to this partition wall 16. A cable I7 is connected to the motor 12 of the submersible pump 11, and a conduit 18 from the discharge port 15 of the submersible pump 11 is led out of the pump chamber 7 via the cap 9.
また、取水管１０には逆洗管１９が連通しており、この
逆洗管１９にエジェクター２０を有する管２１が分岐し

る。Further, a backwash pipe 19 is connected to the water intake pipe 10 , a pipe 21 having an ejector 20 branches to this backwash pipe 19 , and the upper space of the pump chamber 7 is connected to the ejector 20 via a pipe 22 . The structure is such that air can be vented.
次いで、このように構成された取水装置の作用について
説明する。Next, the operation of the water intake device configured in this way will be explained.
先ず、水中ポンプ１１が停止している場合は、海水がポ
ンプ室７の内部において同じ高さまで導入し、空気は水
の上に溜まっている。また、水中ポンプ１１の吸入口１
４は水面下にあって、常にポンプによる汲み上げ可能な
状態になっている。First, when the submersible pump 11 is stopped, seawater is introduced to the same height inside the pump chamber 7, and air remains above the water. In addition, the suction port 1 of the submersible pump 11
4 is below the water surface and can be pumped up at all times.
そこで、水中ポンプ１１のモータ１２によりポンプ本体

管１８を経て外に吐出する。すると、ポンプ室７は気密
構造であるため水の吐出により負圧化して、海水が取水
装置３から取水管１０を経て直ちに吸込まれるのであり
、こうしてポンプ作用によりポンプ室７に海水を吸入し
ながらその水を吐出して汲み上げを行う。Therefore, when the pump body 13 is driven by the motor 12 of the submersible pump 11, water in the pump chamber 7 is discharged from the discharge port 15 through the conduit 18 to the outside. Then, since the pump chamber 7 has an airtight structure, the discharge of water creates a negative pressure, and seawater is immediately sucked in from the water intake device 3 through the intake pipe 10. In this way, seawater is sucked into the pump chamber 7 by the pump action. While doing so, the water is discharged and pumped up.
また、取水装置３が目詰まりを起こすと、逆洗管１９よ
り水を逆流して、目詰まりを除去する。Furthermore, when the water intake device 3 becomes clogged, water is flowed back through the backwash pipe 19 to remove the clog.
また、海水の汲み上げを行う過程において、海水中の空

ジェクター２０により除去する。Furthermore, during the process of pumping up seawater, air and the like in the seawater accumulates in the upper part of the pump chamber 7, but this is removed by the ejector 20.
以上、本発明の実施例の１つについて述べたが、これ以
外の取水の場合にも同様に適用することができる。Although one embodiment of the present invention has been described above, the present invention can be similarly applied to other cases of water intake.
例えば、取水装置は、かならずしも、浮遊式でなくても
良く、海底に設置してもよい。叉、取水装置の形状につ
いては、ここでは特にふれない。For example, the water intake device does not necessarily have to be a floating type, and may be installed on the seabed. However, the shape of the water intake device will not be discussed here.

化し得る。As described above, according to the present invention, since the pump is installed on land, it is possible to easily manage repairs and the like. Since a discharge type submersible pump is used, there are no problems such as inability to pump due to air intrusion. The pump chamber has an airtight structure and quickly sucks in water as the pump works, so even if the volume of the pump chamber is small, there is no risk of inability to pump due to exposure of the suction port. Thereby, the pump chamber can be downsized.
