Water ingress detector installed in a hold, ballast tank and dry space for a bulk carrier ship

摘要

The present invention relates to a cargo hold, ballast tank and cargo compartment forward flooding detection device of a bulk carrier ship. By detecting the difference in temperature and detecting the inundation state, it is possible to accurately detect the inundation state even if the water absorbs water when the cargo loaded on the vessel is in the powder state and the powder absorbs water when the cargo loaded on the vessel is in the powder state. It can be applied regardless of the type of cargo, which increases reliability and has a semi-permanent lifespan by simple structure and operation principle. Relates to a device.;Inundation detection device of the cargo hold for cargo transport ship according to the present invention is an inundation detection device for outputting an inundation signal by detecting the inflow of water when flooded on one side wall surface of a plurality of cargo hold formed in the ship, the immersion detection device is heat generated when the power supply First and second heaters, first and second temperature sensors installed under the first and second heaters to sense a heating temperature of the first and second heaters to generate a signal proportional to the temperature; First and second heaters installed on the outside of the first and second heaters and the first and second temperature sensors, the lower side of which is closed, and the upper side of which is opened, to release heat of the first and second heaters in contact with the flooded water. First and second sensing rods each consisting of two thermal conductors are provided, respectively, and have the same length as the first and second sensing rods, and are formed in a non-parallel manner in which the heating temperatures of the first and second heaters are different from each other. 1st, A protective case is installed above the second thermal conductor, and a submersion signal is supplied when the driving power is supplied to the inside of the case and the temperature difference between the first and second heaters detected by the first and second temperature sensors reaches a predetermined range. It is characterized in that the submerged detection circuit for outputting through the external connection terminal, in another embodiment the length of the second sensing rod 62 is 40 to 60% of the length 100% of the first sensing rod 61 It is formed in the length of the first and second heaters 56, 57 is made in the equilibrium form to equalize the heat generated temperature, the case 51 and the first, second thermal conductors 54, 55 Between the heat insulating material 52 to prevent the heat is diffused into the case 51 and the packing (53c) to prevent water from flowing into the case 51 is characterized in that it is installed.
