To provide a rainwater pump control device enabling a prior standby operation of a rainwater pump only when rainwater flows in.SOLUTION: A rainwater pump control device comprises: a return water amount detection section 13 that detects an amount of water returned by a drainage pump 6, the water accumulating in a pump well 3; an inflow ditch water level change rate calculating section 11 that calculates a water level change rate of an inflow ditch 1, the change rate being only due to rainwater inflow, from a difference between a water level increase value of the inflow ditch 1 being an entrance where rainwater flows in and the amount of returned water detected by the return water amount detection section 13; and a pump control section 12 that predicts in advance that the rainwater flows into the pump well 3 according to the inflow ditch water level change rate detected by the inflow ditch water level change rate calculating section 11 and instructs a rainwater pump 7 to start a prior standby operation based on a pump well water level value detected by a water level gauge 5 provided in the pump well 3.SELECTED DRAWING: Figure 1
【課題】雨水流入時のみで雨水ポンプの先行待機運転を可能とする雨水ポンプ制御装置を提供する。【解決手段】 ポンプ井３に溜まった水を排水ポンプ６にて返送した水量を検出する返送水量検出部１３と、雨水が流れ込む入口となる流入渠１の水位上昇値と返送水量検出部１３で検出した返送水量の差分から雨水流入のみで流入渠１の水位変化率を算出する流入渠水位変化率演算部１１と、流入渠水位変化率演算部１１にて検出した流入渠水位変化率により、ポンプ井３に雨水が流入することを事前に予測しポンプ井３に設置した水位計５にて検出したポンプ井水位値に基づき雨水ポンプ７に対し先行待機運転要求を行うポンプ制御部１２とからなる雨水ポンプ制御装置。【選択図】図１
