Abstract

The invention relates to the technical field of ships, in particular to a water flow impacting system of a ship ballast tank. The water flow impacting system comprises a first water spray nozzle group composed of a plurality of first water spray nozzles, a second water spray nozzle group composed of a plurality of second water spray nozzles, and a water pump, wherein the first water spray nozzle group is arranged on the side wall of the ballast tank, and the second water spray nozzle group is arranged at the bottom of the ballast tank. The water inlet end of the water pump communicates with a water source, and the water outlet end of the water pump supplies water to the first water spray nozzle group and the second water spray nozzle group. When ballast water is injected into the ballast tank, the first water spray nozzle group and the second water spray nozzle group are opened, water flow sprayed from the first water spray nozzle group and the second water spray nozzle group can achieve water flow disturbance to sediment in ballast water, sediment can be effectively prevented from forming sludge after being settled at the bottom of the ballast tank, time required for manual removing of sludge is shortened, and time spent in harbors of ships is shortened.

Description

technical field

[0001] The invention relates to the technical field of ships, in particular to a water flow impact system of a ship's ballast tank. Background technique

[0002] In cargo ships transporting crude oil or containers, ballast tanks are provided to ensure the stability of the ship's hull during navigation. Usually, the ballast tank is filled with ballast water when there is no cargo such as crude oil loaded, and the ballast water is discharged when crude oil or containers need to be loaded, thereby adjusting the buoyancy of the hull to stabilize the hull.

[0003] Especially for large transport ships, the amount of ballast water is even as high as 100,000 tons. In some cases (especially when the ship is in a port, estuary and other sea areas), the ballast water injected by the ship contains a large amount of sediment. After a long voyage, The sediment deposits at the bottom of the ballast tank to form a hard and thick silt layer, which requires a lot of manpower...
