Description

The present invention relates to a drain clogging notification device. More specifically, the present invention relates to a drain clogging notification device that notifies when a drain provided on a rooftop is clogged and water accumulates on the rooftop.

It is common practice to provide a waterproof layer on the roof of a building using construction methods such as asphalt waterproofing, sheet waterproofing, and paint film waterproofing. If water leaks occur in the waterproof layer and is detected late, it can cause severe damage to the building. Therefore, various methods have been devised to detect water leakage from the waterproof layer.

For example, Japanese Patent Application Laid-open No. 2004-233142 (Patent Document 1) describes a conductive layer laid between a waterproof layer and a building frame, a first electrode electrically connected to the conductive layer, and a reinforcing bar embedded in the building frame. a second electrode that is electrically connected; a current measuring device that measures electrical conductivity between the first electrode and the second electrode; and a current measuring device that detects water leakage based on measurement data of the current measuring device. Disclosed is a water leakage detection system that detects water leakage from a waterproof layer mounted on the frame of a building structure, and has a judgment means for making a judgment.

The electrode does not need to be made of a single metal or alloy; it may be a base material plated with a metal or alloy, or a base material coated with a conductive ink containing a metal or alloy. There may be.

Since the first electrode 34 and the second electrode 35 are made of different metals or alloys, the first electrode 34 and the second electrode 35 have different ionization tendencies. Therefore, when the drain is clogged and water accumulates on the roof and the water level exceeds the first distance H, the water detector 3 is immersed in water, the water behaves as an electrolyte, and the first electrode 34 and the second A potential difference is generated between the first electrode 34 and the second electrode 35, and the first electrode 34 and the second electrode 35 function as a battery, and the battery is used as a power source to drive the transmitter 4 and transmit a signal. The signal is received by the receiver and causes the receiver to indicate that the drain is clogged and water is collecting on the roof. The receiver is, for example, a smartphone or a computer.

By using the first electrode 34 and second electrode 35 made of different metals or alloys, the first electrode 34 and the second electrode 35 generate their own power, so a separate power source is not required. Therefore, the device can be downsized, easy to install, and requires no maintenance such as replacing the power source.
