JP2000064411A - Water cut-off plate by buoyancy - Google Patents

Abstract

PROBLEM TO BE SOLVED: To perfectly prevent the flooding by providing a water collecting lid for receiving the water penetrating into a side-ditch and a rib for pressing a water cut-off plate to the opposite side to the water penetrating direction of the side-ditch while supporting the water collecting lid, and raising the cut-off plate by use of the buoyancy generated in the penetrated water receiving side- ditch. SOLUTION: A water collecting lid D receives the water penetrating into a side-ditch B, and a rib C presses a water cut-off plate A to the opposite side to the water penetrating direction of the side-ditch B while supporting the water collecting lid D and plays the role of a guide for providing the effect of the water cut-off plate A, so that the cut-off plate A is raised by the use of the buoyancy generated in the penetrated water receiving side-ditch B. Since the water used for the buoyancy is regularly drained in a fixed quantity, the cut-off plate A is naturally lowered when the water penetration is stopped. Since the force of the penetrating water is utilized, the water cut-off can be safely performed at low cost without any person.

Description

Description: BACKGROUND OF THE INVENTION [0001] The present invention is required in daily life to prevent inundation of buildings, works and the like. 2. Description of the Related Art Electric operation and the like are expensive and require immediate response by humans, and their use is limited. [0003] The power of inundated water is used to prevent buildings and structures using inundation prevention devices that are inexpensive and safe if maintenance is not performed, even during power outages or when people are absent. If the inundation can be prevented and the inundation subsides naturally,
The water stop plate also returns to its original position. [0004] The apparatus according to the first aspect of the present invention uses the buoyancy of the inundating water to float the water stop plate to prevent the infiltration of water. In order to always drain a certain amount of water, if the inundation stops, the water stop plate naturally goes down. Naturally, the waterstop is made of a material that is lighter and has a certain strength. DETAILED DESCRIPTION OF THE INVENTION When water is flooded, the water stop plate rises due to the buoyancy of the water, and when the water stops flowing, the water stop plate naturally falls. According to the present invention, even if no person is present, no person responds to the inundation, even if there is no power outage or no emergency power supply, it is said that the conventional electric breakwater is expensive. Unlike those that raise doubts about Foolsafe (that something did not work or there was a problem with people's response), it is cheap and always has to put things on top, and there is no garbage. This invention can be used in cases where flooding is often a problem.

Claims (1)

Claims: 1. A water stoppage plate for protecting a building or a workpiece from being flooded, and a water stoppage side groove for generating buoyancy and a water stoppage plate and a side groove floating by buoyancy. It is composed of a water collecting lid that receives incoming water and a power bone that also serves as a guide that exerts the effect of the water stopping plate by pressing the water stoppage plate on the opposite side of the gutter while supporting the water collection lid. Drainage is provided so that the water stoppage naturally returns to its original position when the inundation stops.
