The invention discloses a ship drainage
system which is mounted on a ship and comprises a drainage
pipe, a first
sewage disposal structure and an anti-
backflow structure are arranged at the drainage
pipe, and the drainage
pipe is connected with a water pump; the
water pumping pipe is provided with a second
sewage disposal structure, sediments in the
water pumping pipe are cleaned through the second
sewage disposal structure, and the
water pumping pipe is connected with a water pump; the water pump is installed on the ship, a water passing opening is formed in the ship, and the water pump is connected with the water passing opening through a connecting pipeline; the liquid level detection
assembly is used for detecting the liquid level in the ship, when the liquid level is higher than a preset threshold value, a
signal is sent to the
control system to control the water pump to be started, and liquid in the ship is pumped out; and the
control system is used for controlling the first sewage disposal structure, the second sewage disposal structure and the water pump. According to the ship drainage
system, sediments in the drainage pipeline can be cleaned, the drainage efficiency is improved, and the ship drainage
system belongs to the technical field of ship drainage.
