[0002] After the ship was launched, the bilge water equipment on board had not been tested. The cargo hold often rained during the rainy season and the cooling fan of the ventilation system produced a lot of condensed water during operation, which was discharged into the cargo hold. This caused a lot of water to accumulate in the cargo hold, and the equipment was easily soaked in water. The paint in the hold could not be applied normally, which seriously affected the production progress. Therefore, a lot of manpower and material resources were needed to carry a submersible pump to the cargo hold for drainage every day, and the work efficiency was extremely low.

[0039] It can be understood that when the water level in the cargo hold 60 rises, the floating member 20 rises, so that the second boss 221 disengages from the corresponding slot 311, and then the other second boss 221 is inserted into the other slot 311, driving the rotating member 30 to rotate, and the rotating member 30 drives the pressing plate 32 to rotate counterclockwise. When the water level in the cargo hold 60 rises to a preset position, the pressing plate 32 rotates to the opening button 13 to squeeze the opening button 13, and the water pump 40 is started to pump out the water inside the cargo hold, so that the water in the cargo hold 60 can be discharged in time, and there is no need for employees to stare at the water level changes in the cargo hold 60, so as to achieve the purpose of automatic drainage.
[0040] The opening button 13 and the closing button 14 are spaced at an angle of 180°. The opening button 13 is located below the closing button 14. When the water in the cargo hold 60 is discharged and the water level drops, the counterweight 50 pulls down the floating member 20 so that the floating part 21 always floats on the water surface. At the same time, the sliding part 22 also moves downward, and through cooperation with the rotating member 30, the rotating member 30 rotates clockwise, and the pressing plate 32 rotates clockwise. When the pressing plate 32 squeezes the closing button 14, the water pump 40 stops running, and the cargo hold 60 stops being drained at this time.
