DESIGNED WATER LEVEL WATER SUPPLY APPARATUS

摘要

PPROBLEM TO BE SOLVED: To provide a designed water level water supply apparatus which can always automatically supply water to a water supply target in a designed water level without an electric source and manpower for supplying water to the water supply target, can be made at a low cost, does not need a running cost, is quiet on operation, and can be used at various places such as roads or building rooftops, and to provide a designed water level water supply method. PSOLUTION: The designed water level water supply apparatus includes a water level-adjusting tank 2 for once receiving water to be supplied from a water supply source to a water supply target, and a designed water level water supply mechanism 4 for controlling a water level in the water level-adjusting tank to keep the designed water level of the water supply target and simultaneously for automatically supplying water to the water supply target. The designed water level water supply mechanism 4 includes a screw shaft 5 which is disposed in the water level-adjusting tank 2 and can be rotated by an outer force, a lifting or lowering guide 9 which is lifted or lowered by the rotation of the screw shaft 5, a water supply port 10 which is disposed on the lifting or lowering guide 9 and discharges water supplied from the water-supply source 13 through a flexible pipe 11, and a float valve 12 for opening or closing the water supply port 10 in response to the water level in the water level-adjusting tank 2.
