Abstract
Description
Technical Field
[0001] This invention relates to the field of shipbuilding technology, specifically to a modular honeycomb core panel ship and its construction method. Background Technology
[0002] Traditional shipbuilding typically employs the welding of heavy, solid steel plates to form a single hull. This structure presents numerous problems in actual production and use: First, steel consumption is extremely high; a typical 10,000-ton ship can consume thousands of tons of steel, accounting for approximately 30% of its actual load capacity, directly leading to high shipbuilding costs. Second, the manufacturing process relies on complex hull forming and manual welding techniques, resulting in a lengthy construction cycle; the construction of a 10,000-ton ship usually takes several months to half a year, leading to low production efficiency. Finally, the ship's heavy weight results in high fuel consumption during navigation, and traditional single-hull or simple double-hull structures lack independent sealed compartment designs, leading to poor buoyancy. Once a compartment is damaged, it can easily cause a sinking accident. In addition, fuel-powered ships also suffer from high noise levels and severe environmental pollution.
[0003] Existing lightweight ships mostly use lightweight materials such as aluminum alloys and composite materials, which can reduce the hull weight, but the material costs are high and the structural strength is insufficient to meet the navigation requirements of large ships. Although modular shipbuilding technology is applied, the modules are still traditional steel structures, which cannot solve the fundamental problems of high steel consumption and high energy consumption. In addition, existing ship energy systems are mostly driven by single fuel oil or simple new energy auxiliary power supply, lacking intelligent energy distribution logic and low energy utilization. Energy storage devices are not precisely matched with the ship's operating conditions in terms of capacity and temperature adaptability, making it difficult to meet the stable operation requirements in the complex marine environment.
[0004] In summary, there is an urgent need for a modular honeycomb core panel ship and its construction method that can balance lightweight, high strength, anti-sinking performance, low energy consumption, and high manufacturing efficiency. Summary of the Invention

After splicing, the sealing performance of the module connection seams is tested by air pressure test method. At the same time, the compartment division and basic pipeline laying are completed.

It is connected to the front panel and the bottom plate by pulsed gas metal arc welding, and the strength of the welded joint is not less than 90% of the strength of the base material. Specifically, the independent sealed compartments are formed by a honeycomb sandwich structure enclosing the panel and bottom plate. The volume of a single compartment is 1-11m³. The compartments are equipped with 0.5-1mm thick sealing partitions to ensure that damage to a single compartment does not affect the sealing of other compartments.
[0022] Specifically, the density of the honeycomb core panel module 2 is less than that of water (≤900kg / m³), and the weight of a single module is only 1 / 5 of that of a traditional steel module of the same volume.

[0024] Specifically, the ship's electrical system has a built-in energy distribution controller, which uses a PLC control module to dynamically distribute electrical energy according to the logic of "solar energy priority, wind energy supplementation, and natural gas as a backup".
[0025] Specifically, an energy storage device is installed, using lithium iron phosphate battery packs; the drive system adopts an all-electric propulsion method, including a permanent magnet synchronous propulsion motor and an adjustable pitch propeller, to achieve stepless speed regulation.
