The present invention relates to a ship air pipe closing device equipped with a heating device for ice-making and ice-making.

In general, ships are composed of individual tanks, with their bottoms or sides divided into double diaphragms. The reason for this is to prevent water from coming in and completely submerging even if the ship's outer shell is damaged when the ship sails or the ship's shell is damaged. In addition, in order to maintain the equilibrium of the ship, it is important to configure a closed tank. As such, when maintaining the balance of the ship, the water is filled in. At this time, the internal air must be discharged to the outside by the amount of water injected, and in order to discharge the air pipe closing device is required. In addition, the water may be inclined to one place by the waves during the sailing of the ship, or the water may flow back to the place where the air is discharged to one side when the ship collides. This backflow had a problem that the water went into the tank sinks.

As a conventional technique for solving such a problem, Korean Utility Model Publication No. 20-0213730, "Box type air pipe closing device for ships" and the like have been proposed.

The main body 10 includes a housing 19 having a hexagonal shape in which front and rear surfaces are opened and a through hole 17 formed in a center of a lower surface thereof. The front plate 13 and the back plate 14 are joined to each opening of the housing 19 by welding. In addition, the fluid opening and closing means 30 for controlling the flow of air or fluid is mounted inside the housing 19. The fluid opening and closing means 30 has a disk buoy 34 having an insertion hole 32 and a fixing hole 33 formed at its lower surface, and the disk buoy 34 has its front and both sides with an open portion. Formed into a closed panel on the back side. The rubber packing 37 is fitted into the insertion hole 32, and the disk buoy 39 reciprocates up and down to linearly contact the rubber packing 37 to prevent the flow of air or fluid. In addition, the blocking film means 50 is coupled to the front plate 13 of the body portion 10.
