Description

The utility model relates to small shipbuilding and can be used in the construction of cargo, passenger, parking and tourist vessels.

The well-known design is “A comfortable traveling small boat with outboard hydraulic motors” having a displacement hull, seats for passengers in the bow and stern superstructure and on open decks, a wheelhouse and as a mover, a propeller, separate cabins with bathrooms are equipped for passengers, the vessel has two outboard reversible hydraulic motors installed in the aft part and having independent from each other control systems for hydraulic motors in frequency and direction of rotation (patent for utility model No. 69831, IPC BV 35/7 3, published on April 2, 2007).

The disadvantages of this design include: increased resistance to movement of the hull, compared with the catamaran scheme, the complexity and high cost of the hydraulic propeller drive system, the inability to disassemble the vessel in the transport envelope for transportation on public roads.

Known design "Raft-catamaran tourist", containing inflatable floats, stringers and cross beams, equipped with pockets for installing stringers, additionally contains containers made in the form of sections of soft waterproof fabric and placed under the shield - deck, and on the shield-deck there is a frame tents, while the transverse beam contains a bracket for attaching the frame of the tent, equipped with holes for threading the stringers, and the attachment unit of the stringers contains a sleeve with a latch. This design is taken as a prototype (patent for utility model No. 48163, IPC B23B 7/08, publ. 08.04.2005)

The disadvantages of this design include the low reliability of inflatable elements, increased, compared with rigid bodies, the resistance to movement of inflatable floats, the inability to use the internal volume of the floats to accommodate auxiliary units. The disadvantages of this design include the lack of an open deck on the ship, the difficulty of mounting an outboard motor and the inability to install a stationary engine, the overall size for transportation on public roads.

The utility model is based on the task of expanding the functionality of a pontoon vessel and increasing the reliability of the vessel.

This problem is solved due to the fact that in a pontoon vessel, consisting of a superstructure installed on a base platform, consisting of two floats and a connecting bridge, a power unit and an outboard motor mounting bracket, according to a utility model, the floats are made rigid, connected to the connecting bridge with using hinges, with the possibility of turning them about the longitudinal axis and laying on the deck of the connecting bridge, and the superstructure is made modular.

In addition, the connecting bridge consists of two longitudinal beams, a set of transverse beams, and a set of deck covering modules forming the deck of the connecting bridge, the superstructure of each type of vessel can be individually configured, and at the same time can be assembled from a set of standard elements (modules).

The ship’s power plant consists of a diesel generator that generates electricity, a control station that allows you to independently control the direction of rotation and the speed of the columns, and two propeller drive columns, each of which in turn consists of an electric motor that rotates a vertical shaft, which in turn through an angular gear installed in the fairing, it drives a pair of coaxial opposing rotation propellers enclosed in a profiled annular nozzle. The electric motor and the drive shaft are enclosed in a housing with shaft lines, combining the entire column structure into a single unit.

The pontoon ship is illustrated by drawings, where

figure 6 is a General view of a cargo-passenger ship

Fig 9 is an external view of a column drive screws

The basic platform consists of two rigid floats 1 connected by a structure consisting of two longitudinal beams and a set of transverse beams 2, and deck coating modules 3. The floats are connected to the deck by hinge elements 4, with locks, and can rotate 180 degrees around the longitudinal axis , to reduce the transport dimension of the platform. In the lower position, the floats are fixed from turning by locks.

The add-in is formed by standard modules and can have a different configuration depending on the number and type of modules used. The basic set of modules includes a compact wheelhouse 5, an extended wheelhouse 6, a passenger seat 7, a side wall panel 8, an end wall panel 9, a roof panel 10, a visor panel 11, a set of rail elements, an outboard motor mounting bracket 12. Structural the elements of the joints of the modules are detachable and allow multiple assembly-disassembly and redevelopment during operation. Joint sealing is provided by removable sealants.

The power plant of the base platform consists of the following elements: diesel generator, battery, switch K, speed regulator and direction of rotation of the engines P, two columns of the propeller drive M1 and M2. A solar panel may be included in the power plant circuit. The screw drive column, in turn, consists of an electric motor 13, a vertical shaft 14, an angular gearbox 15, a pair of coaxial propellers of opposite rotation 16, a profiled annular nozzle 17, a housing with shaft ducts 18.

The basic platform, which is the universal basis for all types of ships, for transportation on public roads is reduced to the transport dimension by turning the floats around the longitudinal axis, while the decks of the floats are laid on the deck of the connecting bridge. A set of modules forming the superstructure of the cargo and passenger-and-passenger version of the vessel is placed between the folded floats and does not need to be dismantled. When using a wide set of modules for an add-in, during transportation the add-in is dismantled. The bracket for mounting the outboard motor of the base platform is used to mount the spare outboard motor, or for the main outboard motor in the case when the platform is not equipped with a standard power plant.

The platform’s full-time power plant allows you to get high propulsive efficiency of the screws, by dividing the engine power into 4 flows, using low-speed, lightly loaded large-diameter screws, using double counter-rotating screws, and using an annular nozzle that creates a tunnel for each pair of screws. The power plant diagram allows you to remove the diesel generator in a soundproof compartment, and to carry out separate power control convenient for controlling the vessel and reversing the propeller drive columns. Ring nozzles provide additional propeller protection.

The design of modular pontoon vessels provides for the manufacture of panel elements of modules and floats from epoxy fiberglass, by the method of vacuum infusion of resin.

Connecting beams are made of aluminum alloy or welded steel.

Heavily loaded hinge elements made of stainless steel.

The power plant of the vessel can be assembled from components that have been mastered by industry and are commercially available. In general, the design does not contain elements and assemblies that are difficult to fulfill at the current level of technology development.
