Sea chest rapid water supply device during ship dry dock

Abstract

The invention provides a sea chest rapid water supply device during ship dry dock period. The device comprises a water supply valve box arranged on a sea chest, a plurality of connecting pull rods penetrating into the water supply valve box are arranged on the water supply valve box, the inner ends of the connecting pull rods are arranged in a T-shaped state and hooked on the edge opening of the sea chest, and nuts are arranged at the outer ends of the connecting pull rods. The water supply valve box is fixed on the sea chest through nuts. The sea chest rapid water supply device has the beneficial effects of being stable in performance, convenient to operate and implement and capable of meeting the water supply requirement for normal operation and use of ship equipment and a system of a ship in the dry dock period; meanwhile, the technical defects that in a traditional construction method, many types of work are involved, procedures are complex, the labor input is large, the period islong, and ship body outer plate base metal damage is caused to a certain degree can be effectively overcome, production cost saving, labor efficiency improving and product construction quality improving are facilitated, and the construction period of ships in dock engineering is shortened.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, and in particular relates to a fast water supply device for a seabed door during dry docking of a ship. Background technique [0002] The seabed door is generally set on the side of the ship below the waterline or on the outer plate of the bottom of the ship, and is a channel for the ship to draw seawater or fresh water to the outside. The water is drawn into the seawater pipeline by the water pump through the seabed door and then enters the various systems of the ship. The water extracted from the seabed door is mainly used as cooling water for ship equipment, and the heat generated during the operation of cooling equipment; the ship’s ballast water is used to adjust the ship’s state; the ship’s fire-fighting water is used to ensure the safety of the ship; It is an important guarantee for normal navigation at sea and the functional operation of various types of equipment and systems.
