Description
Technical Field
The invention belongs to the technical field of ship construction, and particularly relates to a rapid water supply device for a submarine door during ship dry dock.
Background
The sea bottom door is generally provided on a side or bottom outer plate of the ship below a waterline, and is a passage for pumping seawater or fresh water to the outside of the ship. Water is pumped into a seawater pipeline by a water pump through a sea chest to enter each system of the ship. The water extracted by the sea chest is mainly used as cooling water of ship equipment, and the cooling equipment generates heat during operation; adjusting the state of the ship by using ship ballast water; the use of the fire-fighting water of the ship ensures the safety of the ship; the ship water-making system is used for making purified fresh water and the like; the method is an important guarantee for the ship to normally sail on the sea and for various equipment and systems to realize functional operation.
During the maintenance stage when the ship enters the dock, the ship equipment and the system cannot be supplied with water or stop running due to no external water source in the dock engineering process. During dry dock, on the one hand the vessel needs to be supplied with fire water normally for safety reasons; on the other hand, in order to flexibly organize engineering in the dock, the equipment is operated and debugged if needed. Under the condition, an external water source is required to be introduced to continuously supply water to the submarine door, normal supply of seawater of the ship is guaranteed, and the equipment and the system can be normally operated and used.
The conventional method is to weld a temporary water inlet valve box on the hull structure of the outer plate of the submarine door, and externally connect a water supply pump set through a connecting pipeline to provide water source for the submarine door. However, the traditional construction method for welding the water supply valve box has complex construction process, and generally comprises the steps of dismantling a submarine gate grating, dismantling a submarine gate blow-off pipe and welding the valve box. Cutting off a valve box before the ship is undocked, batch grinding a cut part, repairing paint, reinstalling a blowing pipe, reinstalling a grating and installing a safety pin.
The traditional method has a plurality of defects: the method has the advantages of large variety of work, complex working procedures, large labor input, long period and incapability of effectively guaranteeing quality supervision in the construction process due to damage to the hull outer plate parent metal to a certain extent. Is not beneficial to saving the production cost, improving the labor efficiency and improving the product quality.
