PURPOSE:To conduct a current leaking into water inside the body of a water purifying deice from the feeder part of an ultraviolet sterilization lamp, to an area outside the purifying device and thereby prevent an electric shock accident by providing a conductive electric leakage prevention element which covers a submersible ultraviolet sterilization lamp on the lower surface of a supporting plate. CONSTITUTION:A conductive electric leakage prevention element 23 covering an ultraviolet sterilization lamp 19 is provided on the lower surface of a supporting plate 11. This electric leakage prevention element 23 is formed with a conductive reticulate body of at least, 10-mesh size. If a water-cooling jacket 18 and the ultraviolet sterilization lamp 19 on a water purifying device with the electric leakage prevention element 23 are damaged by an external impact and the current leaks into water from the feeder part of the lamp 19, the current is conducted to an area outside the water purifying device through the electric leakage prevention element 23. Consequently, an electric shock accident in a park pond can be prevented to protect fish against fatal electric shock. |
