Abstract

PURPOSE: To prevent the sea water from infiltration a method wherein at the tip opening part of an air ventilating pipe with which a light buoy body with built-in air cells and the atmosphere are connected, are provided both a valve seat with a connecting hole and a valve of small specific weight, and the connecting hole can be closed when the sea water comes in.
CONSTITUTION: In the tip openings 2b, 3b of air ventilating pipes 2, 3 for ventilating the air of air cells built in a floating light 1 is provided a protective device from infiltration of the sea water, which is composed of a valve seat 8 with a connecting hole 9 in the center and a valve seat container 7 with a valve body 11 of small specific weight like a ping pong ball in the lower part. Usually, the valve 11 is located under the container 7 and ventilated through the connecting hole 9. Though the floating light is inclined, the front ends of the air ventilating pipes are dipped in the sea water and the water comes in from A, the valve 11 closes the connecting hole 9 and the sea water cannot enter the hole.
