Problems solved by technology

The existing hole opening method needs to be drilled once in the stage of subsection production, and then drilled again after the general assembly of sections, and the line marking operation in the dock will occupy the working time of the accuracy measurement personnel, prolonging the construction of the ship in the dock stage cycle

Embodiment Construction

[0030] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0031] In the present invention, unless otherwise clearly specified and limited, a first feature being "on" or "under" a second feature may include direct contact between the first and second features, and may also include the first and second features Not in direct contact but through another characteristic contact between them. Moreover, the first feature being "on" the second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is horizontally higher than the second feature. "Below" the first feature below the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the level of the first feature is smaller than that of the second feature.

Abstract

The invention discloses a method for opening grille holes of a seawater tank and a ship section. The method for opening the grille holes of the seawater tank comprises the following steps of establishing a ship hull coordinate system in computer software; according to the installation area range of the seawater tank grille, creating a ship hull plate model corresponding to the installation area range; according to the sizes and shapes of the grille holes of the seawater tank, establishing a hole-opening area model; combining the hole-opening area model and the ship hull plate model to form a fitting model; taking a reference structure as a benchmark, performing a plurality of sectioning on the fitting model, marking intersection points between sections and the hole-opening area model on the surface of the ship hull plate model, and taking the intersection points as reference points; connecting reference points to obtain a hole-opening edge line of the grid holes of the seawater tank; and finally drawing a hole-opening scribing pattern and carrying out hole opening. According to the method for opening the grille holes of the seawater tank, computer-aided design is adopted, and accurate hole opening of the grid holes of the seawater tank is completed in a sectional construction stage, the precision measurement and the scribing time of a dock stage are saved, and the cost required by a secondary hole opening operation is saved.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a method for opening grill holes of seawater tanks and ship sections. Background technique [0002] Ships need a large amount of cooling water to cool their internal power plants and some auxiliary facilities during navigation. For this reason, seawater tanks are usually installed in the ship and holes are opened at the corresponding positions on the outer plate of the ship to allow seawater to enter the seawater through the holes. After the tank is pumped to the cooling pipe for cooling. The sea tank grille needs to be set on the opening to prevent sea creatures or ice floes from being sucked into the sea tank. The existing seawater tank grille opening method is divided into three steps: [0003] In the segmented production stage, according to the approximate installation position of the grille of the seawater tank, a certain size of hole is reduced from the actual size, ...
