Inundation prevention system of public zone

摘要

The present invention is installed in a multi-storey building structure and is a flood prevention system for a common area that prevents the water flowing in due to a leak from spreading to other spaces. A drainage module that shields the drainage passage, and includes a drainage trench having a plurality of drainage holes through which the inflowing water is drained into the drainage passage, and a piping unit connected to the drainage passage and draining water to the outside; A flood detection sensor that detects inflow, a water supply shutoff valve installed in the water supply line of a building structure to block water supply by a control signal, and a control signal to a water supply shutoff valve to block water supply when a flood signal is received from the flood detection sensor It provides a flood prevention system for a common area, characterized in that it includes a flood control module configured to include a control unit for transmitting. According to the above, it is configured so that the water leakage can be stopped and drained through the drainage module and the blocking module, so that the leakage caused by damage to the water pipe and the fire pipe in the common space for each floor of the building structure is effectively prevented from flowing into the elevating facility space. It is possible to prevent flooding of the elevating equipment.
