Description

Technical Field

[0001] The utility model relates to the technical field of oil tank sealing, in particular to a rubber sealing structure used for a ship's oil tank. Background Art

[0002] The oil tank of a ship refers to a tank used to load oil, such as fuel oil, lubricating oil tanks, circulating lubricating oil tanks, dirty oil tanks, etc. Due to the high density of liquids, they are generally located at the bottom of the ship, which is beneficial to the stability of the ship. In order to reduce the influence of the free liquid surface on the stability, most of them are arranged symmetrically with respect to the longitudinal centerline of the ship. The oil tank of the ship directly relies on bolts to squeeze the rubber layer to seal the oil tank opening. However, most of the oil tanks of the ship will shake due to the movement of the ship. The oil loaded inside the oil tank will fluctuate due to the shaking of the ship, which can easily cause the oil to leak through the gaps between the rubber layers. In addition, when the ship shakes, the friction between the rubber blocks will increase. Long-term use will cause the rubber layer to wear and cause oil leakage. Therefore, the present application proposes a rubber sealing structure for ship oil tanks. Utility Model Content

When the ship shakes, the friction between the rubber blocks will increase, and long-term use will cause the rubber layer to wear and cause oil leakage. A rubber sealing structure for ship oil tanks is proposed.

[0006] The sealing mechanism includes a sealing ring, an inner wall of the sealing ring is provided with a sealing groove, an inner top surface of the sealing groove is fixedly connected to a rubber top block, a bottom end of the rubber top block is fixedly connected to an elastic layer, and a bottom end of the elastic layer is fixedly connected to a rubber bottom block.

[0007] Optionally, the fixing mechanism includes a fixing ring, the bottom end of the fixing ring is fixedly connected to the fixing base 1 through a plurality of connecting bolts, and the bottom ends of the plurality of connecting bolts pass through the fixing base 2.

[0008] Optionally, the top end of the sealing ring is fixedly connected to a sealing cover via a threaded connection port, and the sealing cover is located at the top end of the oil tank.

[0009] Optionally, a plurality of sliding grooves are formed on the inner wall of the sealing ring at equal intervals, the inner walls of the plurality of sliding grooves are slidably connected to sliding rods, and the bottom ends of the plurality of sliding rods are fixedly connected to connecting pipes.
