FEEDER SYSTEM

PROBLEM TO BE SOLVED: To attain a long-life by eliminating power storage based on chemical reaction, enable recycling to be carried out to save resources and contribute to an entire cost reduction.SOLUTION: This invention comprises float lifting means 3 in which one end 3ws is connected to a float body 2, a wire member 3w passed through guide parts 3ga, 3gb...is wound up by a taking-up part 3r to sink the float body 2 floated at a water surface Wu down to a specified depth D and at the same time fed out of the taking-up part 3r to float up the float body 2 sunk down to a specified depth D; energy converting means 4 having an electric motor 4m for rotationally driving the taking-up part 3r in a taking-up direction Fr and a power generator 4g for generating electricity on the basis of a rotation of the taking-up part 3r in the feeding-out direction Ff; and mode changing-over means 5 for changing-over mode to a power storage mode for supplying a generated electrical power Pe to at least the energy converting means 4 to perform storage of electricity or discharging mode enabling the generated electrical power Pe to be taken out of the energy converting means 4 and to be used.SELECTED DRAWING: Figure 1 【課題】 化学反応に基づく蓄電を排して長寿命化を図るとともに、再利用を可能にして資源節減を図り、かつ全体のコストダウンにも寄与する。【解決手段】 フロート体２に一端３ｗｓを結合し、かつガイド部３ｇａ，３ｇｂ...を経由させたワイヤ部材３ｗを、巻取部３ｒにより巻き取ることにより水面Ｗｕに浮いたフロート体２を所定の深さＤまで沈めるとともに、巻取部３ｒから繰り出すことにより所定の深さＤに沈めたフロート体２を浮上させるフロート昇降手段３と、巻取部３ｒを巻取方向Ｆｒに回転駆動する電動機４ｍ及び繰出方向Ｆｆにおける巻取部３ｒの回転に基づいて発電を行う発電機４ｇを有するエネルギー変換手段４と、少なくとも当該エネルギー変換手段４に発電電力Ｐｅを供給して蓄電を行う蓄電モード又は当該エネルギー変換手段４から蓄電電力Ｐｅを取出して使用可能にする放出モードに切換えるモード切換手段５とを備える。【選択図】 図１
