It can reduce hull deformation to avoid excessive bending moments and shear forces, and reduce hull vibration. However, after long-term use, a large amount of impurities will accumulate inside the ballast water system, thereby affecting the ballast water treatment system's filtering effect on the water body. Therefore, it is necessary to install equipment in the ballast water treatment device to clean the inner wall of the device in a timely manner.

[0003] Related art relates to a self-flushing sewage discharge device for a ship's ballast water treatment device, comprising a ballast water tank and a first rotating pipe, wherein the top of the ballast water tank is connected to a first support pipe, a motor is provided at the top of the first support pipe, a first connecting pipe is connected to the outer surface of the first support pipe, a second support pipe is provided at the bottom of the ballast water tank, a sewage pipe is provided on the outer surface of the second support pipe, the bottom end of the second support pipe is connected to a water inlet pipe via a flange, a primary treatment filter is provided on the inner wall of the water inlet pipe, a second rotating pipe is provided at the bottom end of the first rotating pipe, a water hole is provided on the outer surface of the second rotating pipe, a reprocessing filter is provided on the inner wall of the ballast water tank, and a cleaning pipe is provided on the outer surface of the first rotating pipe.

However, the oil and water need to be separated, otherwise the oil will enter the ballast water tank and pollute the water. Therefore, it is necessary to develop an oil-water separation sealing structure. Summary of the Invention

[0009] Preferably, a deformation cavity is provided in the sealing rubber.

[0010] By adopting the above technical solution, as the temperature changes, the sealing rubber will expand due to heat or shrink due to pre-cooling.

[0012] By adopting the above technical solution, when the docking column and the fixed column are installed, the lower surface of the docking plate is attached to the upper surface of the docking plate. Subsequently, the positioning block is driven by the adjustment component to be inserted into the plug-in slot of the docking plate, thereby improving the stability between the docking plate and the fixed plate, thereby reducing the misalignment between the docking column and the fixed column, and further improving the connection stability between the fixed column and the docking column.

[0020] By adopting the above technical solution, the insertion block first separates the stabilizing block from the sliding rod through the synchronization component, and then the stabilizing block rises to the stabilizing groove under the elastic action of the driving spring. Then, the insertion block continues to be inserted into the insertion groove of the stabilizing block under the action of the synchronization component, and the fixation of the stabilizing block can be completed.
