Abstract

The utility model provides a small plastic ship hull which is made by a rotational molding process. Reinforcing rib plates [2, 3 and 4] are welded on the inner wall of a ship hull shell [1] and/or lengthwise angles [5] are arranged on the outer wall of the ship hull shell. Compared with the prior art, the small plastic ship hull has the advantages that as the reinforcing rib plates [2, 3 and 4] are welded on the inner wall of the ship hull shell and/or the lengthwise angles are arranged on the outer wall of the ship hull shell, the rigidity and the capacity of resisting transverse waves of the ship hull are improved, and a ship with the small plastic ship hull is safer.

Description

A kind of small plastic hull

Technical field

The utility model relates to a kind of small plastic hull.

Background technology

Along with the progress of material technology, the hull construction material has carried out from timber to the iron and steel development to glass-felt plastic.But it is very huge that wooden ship not only consumes timber, and the navigation performance of ship and safety performance, especially wind-proof and wave-proof and fire resistance are all not good enough; Though steel ship navigation performance is preferable stronger with safety, oxidation corrosion not only needs comprehensive application but also application to have relatively high expectations easily, and boats and ships deadweight simultaneously is bigger; Glass steel ship then in the forming process toxic stronger, can not reclaim and non-degradable after scrapping.For this reason; Ship building; Especially the construction material therefor of small boat has developed into plastics; Because the not burn into surface finish of plastics is high, improve its intensity and flame retardance through filling additive easily, poison during fabrication simultaneously little, scrap characteristics such as the back is recyclable, being used to build ship has good prospect.Introduce according to Chinese invention patent application " a kind of working method of plastics ship " (publication number CN101380990); Three kinds of manufacturing approaches of existing plastics ship: the one, compression molding method; It is earlier with plastic plate through each parts of hot-forming hull, at last several kinds of difform hull Moulded plastics spares are welded into plastic hull with ultrasonic welder.The 2nd, cutting, welding fabrication method, it is earlier plastic flagstone to be cut into certain shape, again the plastic plate that cuts is welded into plastic hull with ultrasonic welder.The 3rd, injection molding method, it is first with plastic pellet injection mo(u)lding in the plastic hull mould of different parts, more several kinds of difform hull Plastic Parts is welded into plastic hull with ultrasonic welder.But these three kinds of methods all are to use the sub-assembly of hull structure of moulding in advance through being welded, and for the ship safety of navigation certain hidden danger are arranged.Therefore; Produced again like " small-sized rotational moulding ships and light boats research and design " (Chen Jianhua etc., " Chinese water transport ", the 10th volume; The 9th phase) a kind of method of building the plastics ship with rotational molding technique of introducing; This method can produce the hull that integral production is accomplished, and some is thin but this hull also seems, Hull Strength and carrying capacity also do not match.

Summary of the invention

To above-mentioned deficiency, the utility model is exactly the small plastic hull that will provide a kind of intensity high.

A kind of small plastic hull that the utility model provides is processed by rotational molding technique, on hull shell inwall, welds deep floor and/or at outer wall lengthwise angle is set.

A kind of small plastic hull that the utility model provides welds deep floor and/or at outer wall lengthwise angle is set on hull shell inwall, compared with prior art, the ability that has improved the rigidity of hull and resisted horizontal stormy waves makes ship safer.

Said deep floor is vertically to be welded on the inboard U-shaped plate of hull shell with the ship fore-and-aft direction, is called transversely stiffened plate; Be to be welded on the inboard rectangular plate of hull shell, claim vertical deep floor along the ship fore-and-aft direction; Be to be welded on hull shell installed inside power or the locational plate of steering unit, claim the structure deep floor; Each deep floor welds with its limit and hull shell interior sidewall surface by wide the direction vertical with the hull shell.

Said transversely stiffened plate is formed by three sections, is respectively a hull bottom section, two shipboard sections.

Said lengthwise angle is the two-fold angle; Be that hull shell both sides outer wall connects with the fillet of a fore-and-aft direction between up and down; And fillet both sides and hull shell wall are the rib of a recessed protruding fore-and-aft direction, the two-fold angle of folding mutually up and down that is formed on promptly that fore-and-aft direction extends on the hull shell outer wall of hull both sides.

Description of drawings

Fig. 1 is the ship birds-eye view of the utility model one embodiment, and Fig. 2 is A among Fig. 1---the A section-drawing, and among the figure: 1-hull shell, the vertical deep floor of 2-, 3-transversely stiffened plate (hull bottom section), 4-transversely stiffened plate (shipboard section), 5-lengthwise angle.

The specific embodiment

A kind of small plastic ship, its hull shell 1 adopt the poly-vinyl material modification after the one-shot forming of rotation rotational molding technique.Also installed the transversely stiffened plate of together vertical deep floor 2 of median ridge and position, midship cabin in the hull additional, transversely stiffened plate has shipboard section 4 and hull bottom section 3.Hull divides a plurality of cabins, and stern is provided with outboard drive set or propeller plant, also is provided with on-hook tail well, and on-hook tail well both sides are provided with the driver's seat, on the hull shell ship stern side of a ship, the reinforcement backplate is arranged, and there is the structure deep floor position that propelling unit is installed in the ship.When the hull casing forming; On the hull shell of hull both sides, respectively formed twice two-fold angle 5 through mold shape; Per pass two-fold angle is seeing it is that the minor face with a level connects between the hull shell-side face top and the bottom on the hull shell lateral cross section, top and minor face form salient angle, and bottom and minor face form re-entrant angle.See the narrow rectangular connection hull shell side wall top and the bottom that one two-fold angle is exactly a section level on the whole, top and rectangular formation fin, lower part and the recessed rib of rectangular formation.The setting of deep floor has increased transverse strength, has improved vertical torque, guarantees to have good impact resistance performance.Increase whole service life, can reclaim after scrapping simultaneously, practiced thrift the energy.
