WATER RESERVOIR FOR WATER SUPPLY IN CASE OF DISASTER

摘要

PROBLEM TO BE SOLVED: To provide a structure capable of swapping water in a large and short body water storage tank having a free water surface with as little water supply as possible.SOLUTION: A water reservoir in which a center pipe extending in a vertical direction is provided at a center of a tank, and the center pipe is divided into upper and lower two portions, and the upper portion is used for outflow and the lower portion is used for inflow. In the upper portion, an inflow pipe penetrates a top plate or a side plate, and then is connected laterally to the upper portion. In the lower portion, a water supply outlet outer pipe penetrates the top plate and is laterally connected to the lower portion. A submersible pump is charged inside the water supply outlet outer pipe, a submersible pump outlet is connected to the water supply outlet outer pipe and is taken out to the outside of the tank through the water supply outlet outer pipe. An upper end of the upper portion of the center pipe is formed into a substantially spherical shape having a straightening plate inside, a large number of holes are made in a surface thereof, and water is injected in all directions from there to flow into the tank. A lower end of the lower portion is connected to a center of a composite trumpet-shaped plate facing toward a bottom plate, and water is passed through multiple straightening plates inside the trumpet, guided through the center pipe lower portion, and then allowed to flow out.SELECTED DRAWING: Figure 1
