Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、例えばガソリン給油所に設置する給液装置
に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a liquid supply device installed in, for example, a gasoline filling station.
例えば給油所では、従来周知のごとく、給油所敷地の
地下にタンクを埋設し、ここにガソリン等の油を貯蔵し
ておき、給液装置として地上に給油装置を設置し、前記
地下の貯油タンクと給油装置とを給油管で連結し貯油タ
ンク内の油をポンプで給油装置に送り込み、給油装置に
設けた給油ホース先端の給油ノズルから自動車に給油す
るようにしている。For example, in a gas station, as is well known, a tank is buried underground in the site of the gas station, oil such as gasoline is stored in the tank, and an oil supply device is installed on the ground as a liquid supply device. And an oil supply device are connected by an oil supply pipe, and the oil in the oil storage tank is sent to the oil supply device by a pump so that the vehicle is oiled from the oil supply nozzle provided at the tip of the oil supply hose provided in the oil supply device.
ところで、この油汲上げ用のポンプの設置場所とし

プ、給油モータなどを組込んでいる。そして、停電時に
給油ポンプが停止した場合の対策手段としては給油ポン
プに着脱自在な手動ハンドルを設けてあり、この手動ハ
ンドルで給油ポンプを駆動して給油できるようにしてい
る。By the way, when the pump for pumping oil is installed at a relatively small underground tank capacity of, for example, 10 kl or less, or when the number of refueling devices installed in one refueling station is small, a fixed type above ground is used. The refueling pump, refueling motor, etc. are installed in the refueling machine case installed upright on the island installed in the above, or in the pump room installed above ground in the suspension type. Further, as a countermeasure against the stop of the fuel pump during a power failure, a removable manual handle is provided on the fuel pump, and the manual handle is used to drive the fuel pump for fueling.
しかし、地下タンクの容量が例えば30kl以上と大きな
ものになり揚程が大きくなったり、あるいは小容量のタ
ンクでも地中深くに埋設して揚程が大きくなると、ポン
プを地上に設置したのでは充分な汲上げ能力が得られな
い。また、給油装置の設置台数が例えば５台以上と多数
になると、個々の給油装置に個別にポンプを設けるので
はコスト的に高いものとなってしまう。However, if the underground tank has a large capacity, such as 30 kl or more, and the head is large, or if the tank with a small capacity is buried deep in the ground and the head becomes large, it will be sufficient to install a pump on the ground. I cannot get the ability to raise. In addition, if the number of refueling devices installed is large, for example, five or more, it would be costly to provide a pump individually for each refueling device.
このため、前記のような場合は、地下タンク内に液中
ポンプ（サブマーシブルポンプ）を１台設置してこのポ
ンプで地下から地上の各給油装置へと油を圧送するよう
にしている。For this reason, in the above-mentioned case, one submersible pump (submersible pump) is installed in the underground tank, and this pump is used to pump the oil from the underground to each refueling device above the ground.
しかし、送液ポンプとしてかかるサブマーシブルポン
プを地下タンク内に設置するタイプの給液装置では、停
電時の対策手段として該ポンプを手動とすることは不可
能であり、停電時には給液不可となってしまう不都合が
ある。However, in a liquid supply device of the type in which such a submersible pump as a liquid feed pump is installed in an underground tank, it is impossible to manually operate the pump as a countermeasure against a power failure, and liquid supply is disabled during a power failure. There is an inconvenience.

給液装置を提供することにある。The object of the present invention is to eliminate the disadvantages of the conventional example, and even in a type of liquid supply device in which a liquid feed pump such as a submersible pump is installed in an underground tank, liquid can be manually pumped from the underground tank during a power failure. Another object of the present invention is to provide a liquid supply device which can ensure safety during manual switching and does not hinder the work of gas stations.
本発明は前記目的を達成するため、地下のタンクに液

接続することを要旨とするものである。In order to achieve the above-mentioned object, the present invention installs a submersible pump in an underground tank, connects a submersible pump connected to the submersible pump to a plurality of submersible devices, and installs the submersible pump in a case of the submersible device. A bypass pipe is connected in the middle of the installed feed pipe via a switching valve having a valve changeover detection switch, and a manual pump is provided in the midway of the bypass pipe, and the submersible pump and the feed pipe on the discharge side of the manual pump are connected. A flow meter is installed on the way, and an electromagnetic valve that opens and closes in conjunction with hanging and unplugging the oil supply nozzle to the nozzle hook or manually opens and closes is provided, and in the valve changeover detection switch, the changeover valve communicates with the bypass pipe side. The gist of the invention is that the valve changeover detection switches are connected in series to the circuit of the motor that drives the submerged pump.
本発明によれば、停電時などの非常時用の手動ポンプ

上げの妨げとなるおそれはない。According to the present invention, since the manual pump for emergencies such as during a power failure is provided in the bypass pipe connected to the liquid supply pipe connected to the submersible pump, the manual pump can be rotated manually to store the water in the underground tank. The liquid is pumped through the bypass pipe. Further, when the normal liquid is pumped by the submersible pump, the manual pump is not located in the middle of the flow path, so that the manual pump does not interfere with the normal liquid pumping.
また、切換弁を手動ポンプ側に切り換えることで液中
ポンプへの通電が絶たれるから、切り換え動作が確実で
あり、安全である。Further, since the submersible pump is de-energized by switching the switching valve to the manual pump side, the switching operation is reliable and safe.
