Double-hull bottom double-hull ship

Abstract

The invention provides a double-hull bottom double-hull ship, which comprises a double-layer hull bottom and a double-layer hull, wherein a foaming layer is arranged in a gap of the double-layer hull bottom or double-layer hull. Preferably, the double-layer hull bottom and the double-layer hull are made of a plastic material and are integrally molded. According to the double-hull bottom double-hull ship, a rotational molding mode is adopted, the integral molding of the double-hull bottom double-hull ship can be ensured, and the molding is uniform, so that a ship hull can keep balance; and the gap can be formed in the double-layer hull by rotational molding, and can be filled with a foam material. The double-hull bottom double-hull ship has the advantages that the foam layer is arranged in the double-layer hull bottom or double-layer hull, so the safety of the ship hull can be increased; when the double-hull bottom double-hull ship encounters an external force, the foam layer can form buffering, so the safety of the ship hull can be ensured, even if water enters a cabin, the whole ship hull can float on a water surface by virtue of the buoyancy of the foam layer, and life and property security can be ensured; in addition, the double-hull bottom double-hull ship is subjected to rotational molding by adopting plastic, so that the manufacturing cost is relatively low.

Description

technical field [0001] The invention relates to the field of ships, in particular to a small double-bottom double-hull ship. Background technique [0002] In 1879, the world's first steel ship came out, marking the arrival of the era of steel ships. Up to now, the materials used in the manufacture of small boats with a length of less than 20 meters are four categories before plastic boats: wood, metal, cement, and fiberglass, each with its own advantages and disadvantages. [0003] 1. Timber: the most primitive shipbuilding material. Due to the limitation of forest resources, sustainable use is impossible. Wooden boats have a large power matching coefficient, a long construction period, and high maintenance and operating costs. [0004] 2. Metal: steel or aluminum alloy, high cost and long construction period; not resistant to salt, acid and alkali, high maintenance cost; large power matching coefficient, high operation (navigation) cost. [0005] 3. Cement: This materia...

Due to the limitation of forest resources, sustainable use is impossible

Wooden boats have a large power matching coefficient, long construction period, high maintenance and operating costs

[0004] 2. Metal: steel or aluminum alloy, high cost and long construction period; not resistant to salt, acid and alkali, high maintenance cost; large power matching coefficient, high operating (navigation) cost

[0005] 3. Cement: This material is mainly used for small inland river boats, with the lowest cost, but it is bulky, poor in strength and toughness, and extremely unsafe

[0006] 4. FRP: It is made of glass fiber and epoxy resin. It is not environmentally friendly to manufacture and use, especially after it is scrapped, it will become a serious environmental problem.

Afraid of sunlight; hydrophilic, so not heat-resistant or cold-resistant; lightly touched and fragile, high maintenance cost
