Description
Technical Field

Background
Watertight doors are a common component in boats. The watertight door needs to be suitable for not only the parts of the ship cabin below the main deck and the shaft tunnel, but also the parts of the platform deck and the like. Its performance needs to meet the latest revised SOLAS convention. When the boats meet dangerous situations, the boats can enter water, so that the whole boats are prevented from entering water, more serious dangerous situations are avoided, and the boat cabins are required to be separated. Watertight doors are the most common closure means. Watertight doors are often installed at the passage locations of boats.
The watertight door comprises a door frame, a door body and a hydraulic cylinder. The driving end of the hydraulic cylinder extends out to push the door body to move along the portal frame so as to close the boat passage. And the driving end of the hydraulic cylinder contracts to pull the door body to reset along the portal frame so as to open the boat channel.
When the boat encounters dangerous situations, the boat can swing seriously, and meanwhile water can enter the engine room. In order to avoid water filling the entire boat, the boat channel communicating with the intake nacelle needs to be closed. When the water inflow in the cabin is increased, larger water pressure can be formed, and leakage can occur after the door body and the door frame cannot bear the water pressure. After the hydraulic cylinder works for a long time, the hydraulic cylinder leaks, the thrust to the door body is weakened, and when the boat swings, the door body can generate certain displacement, and the leakage between the door body and the door frame can be caused. The inertia generated when the boat swings drives the equipment of the boat to collide with the door body, and after the door frame is impacted, leakage can also occur between the door body and the door frame. How to solve the problem that watertight doors can provide higher tightness when a boat encounters a dangerous situation becomes important.
