どの上水道断水時には貯水槽の機能を果す給水用
の貯水槽に関するものである。[Detailed explanation of the invention] [Industrial application field] This invention is normally used to supply water to each floor of high-rise buildings such as city buildings and condominiums, and serves as a water tank during water supply outages such as earthquakes. This relates to a water tank for use.
［従来技術］
従来、高層住宅やビルの各層に給水するために

る（改訂・「貯水槽の衛生管理」175ページ、ビル
管理教育センター）。[Prior Art] Conventionally, in order to supply water to each floor of a high-rise residence or building, as shown in Figure 3, a water distribution pipe 1 was first connected to a receiver installed on the lowest floor of the building (usually the first or second floor underground). Water is received in a water tank 21, and the water in this water tank is pumped by a water pump 7' to an elevated water tank 22 installed on the top floor of the building (usually on the roof of a tower), and from this elevated water tank to each floor. Water is supplied by natural flow through a water supply pipe that is installed hanging down to the washbasin or toilet bowl (revised "Water Tank Hygiene Management" page 175, Building Management Education Center).
しかし、この受水槽では配管水圧に悪影響を与
えないように、その水面が大気に接して自由に上
下する、いわゆる自由水面を形成することが必要
であり、そのため露出した水面から汚水が流入し
たり、小動物、虫などが侵入したり、空気と接触
して残留塩素量が低下して上水使用の少ない休日
などは水質劣化のおそれが生じたりする。 However, in order to avoid adversely affecting the water pressure in the pipes, this water tank needs to have a so-called free water surface, where the water surface freely rises and falls in contact with the atmosphere, which prevents sewage from flowing in from the exposed water surface. , small animals, insects, etc. may enter the water, or the amount of residual chlorine may decrease due to contact with the air, leading to a risk of water quality deterioration on holidays and other occasions when water usage is low.
一方、地震などにより上水が断水する場合に備

３′と夫々連通する構成を示している。 On the other hand, an ``emergency water storage device'' proposed by the applicant in case water supply is cut off due to an earthquake, etc.
(Japanese Patent Publication No. 59-34628), as shown in Fig. 4, a water storage tank 4' is constructed by connecting large diameter pipes, and a water supply pipe 23 and a water collection pipe 24 are arranged inside this pipe. hand,
A configuration is shown in which the water distribution main pipe 1' communicates with the water supply branch pipe 2' and the discharge branch pipe 3', respectively.
なお、この両分岐管の途中に緊急遮断弁５′を
夫々具えており、通常は弁を開いて配水本管１′
から貯水槽４′へ上水が流入、流出して水が常に
入れ替わるようなバイパス形式を採つている。 In addition, each of these two branch pipes is equipped with an emergency shutoff valve 5' in the middle, and normally the valve is opened and the main water pipe 1' is closed.
A bypass system is adopted in which water is constantly replaced by flowing water into and out of the water storage tank 4'.
地震などが発生すると弁が閉じて貯水槽４′内
の新鮮な水を緊急時の飲料に供することができる
ものである。 When an earthquake or the like occurs, the valve closes and fresh water in the water tank 4' can be made available for drinking in an emergency.
［考案が解決しようとする問題点］
上記二つの従来技術を組合わせて、高層ビルな
どの近くに貯水槽を地下埋設したり、地下室に配
置したりすることができる。[Problems to be solved by the invention] By combining the above two conventional techniques, a water tank can be buried underground near a high-rise building or the like, or placed in a basement.
水は常に入れ替つて水質が劣化することなく新
鮮な上水を建築物内に給水できるし、一旦地震な
どが発生したときは、この新鮮な水を飲料に供す
る貯水槽の役割も兼ねることができる。 The water is constantly replaced, allowing fresh tap water to be supplied into the building without degrading the quality of the water, and in the event of an earthquake, etc., it can also serve as a water storage tank to supply this fresh water for drinking. .
ところが、この形式の貯水槽の場合は自由水面

ち貯水槽から急に水がひき出され槽内および配水
本管１′の下流側水圧が低下し、下流側使用者に
大きな悪影響をもたらす（この点が従来、自由水
面を採つてきた理由でもあるが）。 However, in the case of this type of water storage tank, it is not a free water surface, but a type of sealed pressure vessel, so when the water storage tank is piped indoors and pumped up, the amount of water used in the building suddenly increases. Water is suddenly drawn out from the water tank, lowering the water pressure inside the tank and downstream of the water distribution main 1', which has a major negative impact on downstream users (this is also the reason why free water level has been adopted in the past). but).
本願考案は上記二つの従来技術を組合せた場合
に生じる障害を解決し、建築物内の使用水量の変
動があつても、本管下流側に水圧の変動が起らな

する。 The present invention solves the problems that occur when the above two conventional technologies are combined, and provides a closed type water supply storage system that does not cause fluctuations in water pressure on the downstream side of the main pipe even if the amount of water used in the building fluctuates. The purpose is to provide a tank.
［問題点を解決するための手段］

Both ends of the pipe body communicating with the existing water distribution main pipe 1 via the water supply branch pipe 2 and the discharge branch pipe 3 are closed, and emergency shutoff valves 5,
5, a pressure tank 5 that communicates with the water tank 4 and is equipped with a pneumatic means, a means for detecting the water level in the pressure tank 5, and a system that responds in response to a command from this detection. The above-mentioned problem was solved by providing a water pump.

る。 On the other hand, a pressure tank 6 is provided which communicates with the water storage tank 4, and since this pressure tank 6 is equipped with a pneumatic means, the water flowing into the tank is always subjected to a constant pressure and is sent to each layer in the high-rise building. Water can be pumped and supplied.
建築物内の使用のため圧力槽内の水位が降下
し、あらかじめ設定してあるレベルに達したとき
は、その状態を検知して直ちにこの検出に命令さ
れて揚水ポンプが作動して貯水槽４より水を吸引
して設定レベルに水位が達して作動が停止する。 When the water level in the pressure tank drops due to use in a building and reaches a preset level, this condition is detected and the water pump is immediately activated by this detection to pump water into the water storage tank 4. It sucks in more water and stops operating when the water level reaches the set level.
なお、地震など異常発生のため断水したときは
緊急遮断弁５，５が閉じて貯水槽４、圧力槽６に
充満している上水は緊急の飲料水などとして使用
に供せられる。 In addition, in the event of a water outage due to an abnormality such as an earthquake, the emergency shutoff valves 5, 5 are closed and the tap water filling the water tank 4 and pressure tank 6 is made available for use as emergency drinking water.

ものが望ましい。 The water storage tank 4 that communicates with the water distribution main pipe 1 through the water supply branch pipe 2 and the discharge branch pipe 3 has a large diameter (for example, 2.6 m).
It is preferable to connect several centrifugal cast iron tubes with cement-lined inner surfaces and seal both ends with convex lids.
この貯水槽４は地中に埋設してもよく、又は建
築物の最下層床面上に据えつけてもよい。 This water tank 4 may be buried underground or may be installed on the lowest floor of a building.
また、この槽にはバルブ８、空気弁９を具え、

動を命令し昇圧する。 The lift pump 7 is a centrifugal pump, and its power source is connected to a water level detector 10 hanging down inside the pressure water tank 6, which detects whether or not the tip is in contact with liquid and sends a signal to the lift pump 7. Command to start or stop. A pressure detector 11 is attached to the pressure tank 6, and is connected to the power source of the compressor 12.The pressure sensor 11 is connected to the power supply of the compressor 12, and detects a drop in the pressure inside the tank due to a drop in the water level, and turns on the compressor 12 in order to restore the pressure to a constant pressure. Command the operation and increase the pressure.
建築物内での使用水量が減少し圧力槽内の水量
