MANHOLE PUMP SYSTEM, MANHOLE PUMP CONTROL DEVICE AND MANHOLE PUMP CONTROL METHOD
To provide a manhole pump system that has a low load of restoring a pump and that can suppress occurrence of noise more than when using an engine type pump.SOLUTION: A manhole pump system comprises pumps 23a and 23b for sucking and discharging liquid in a storage tank, a power supply passage R1-1 for supplying commercial power, a power supply passage R2-1 for supplying electrical power of a portable type storage battery 61, power supply passages R3-1 and R3-2 for supplying electrical power of a battery in an electric vehicle 65 to a pump, an inverter 311 for converting a characteristic of storage power in matching with commercial power, a V2 L66 for converting a characteristic of electrical power of the battery, a change-over switch 33 that switches power supply passages R1-1, R2-1 and R3-2 and that supplies any of commercial power, storage power and electrical power of the battery in the electric vehicle 65 to the pumps 23a and 23b, and an inverter 312 with a soft start function of suppressing a start current of the pumps 23a and 23b.SELECTED DRAWING: Figure 4
【課題】ポンプの復旧に係る負荷が小さく、また、エンジン式のポンプを使うよりも騒音の発生を抑止できるマンホールポンプシステムを提供する。【解決手段】貯留槽の液体を吸い込み、吐出するポンプ２３ａ、２３ｂ、商用電力を供給する電力供給路Ｒ１－１、可搬式の蓄電池６１の電力を供給する電力供給路Ｒ２－１、電動車両６５のバッテリの電力をポンプに供給する電力供給路Ｒ３－１、Ｒ３－２、蓄電電力の特性を商用電力に合わせて変換するインバータ３１１、バッテリの電力の特性を変換するＶ２Ｌ６６、電力供給路Ｒ１－１、Ｒ２－１、Ｒ３－２を切り替えて、商用電力、または蓄電電力、電動車両６５のバッテリの電力のいずれかをポンプ２３ａ、２３ｂに供給する切替スイッチ３３、ポンプ２３ａ、２３ｂの始動電流を抑止するソフトスタート機能付インバータ３１２と、によりマンホールポンプシステムを構成する。【選択図】図４
