Description

The invention relates to the field of shipbuilding, in particular to modular, collapsible craft: barges, lighters, pontoons, floating platforms, floating islands, etc. made of separate blocks (modules) of buoyancy.

From the prior art, collapsible floating craft are widely known in which non-collapsible sealed steel or plastic containers are used as buoyancy blocks, including steel modules made in the standards of transport dimensions of 20 and 40 foot ISO containers, which are connected at the assembly site each other along the perimeter with the help of mechanical coupler locks of various designs into a single floating craft.

The general disadvantages of the solutions presented in analogues and prototypes are as follows:

Large metal consumption and capital intensity of the non-separable structure of individual floating block-modules due to the need to ensure strength and tightness, which is achieved by making the deck, walls and bottom of the module made of steel sheet at the factory.

The overall dimensions of the individual floating block-modules require a larger number of cargo platforms during transportation to the assembly site, since for the transportation of one module, one separate seat is required on a transport automobile or railway platform.

The closest analogue for the claimed invention is the patent of the modular barge manufacturer Poseidon Barge Corporation US 8,079,320 B1, which discloses a frame perimeter system for barge construction. The design provides for the execution of the container module with fastening fittings in the dimensions of standard multimodal 20 and 40 foot ISO containers. Structurally, the buoyancy module is made as a single welded structure of a steel supporting frame, a deck and bottom load-bearing set, steel sheet sheathing on all sides of the module and attachment points (locks) on the outer sides of the block module for assembling a single floating vehicle from separate modules. This solution has the same aforementioned disadvantages, namely, the non-separable design of individual floating modules, large weight and overall characteristics of the structure during transportation.

The task of the proposed solution is to provide the buoyancy module with a collapsible design,

The technical result of the proposed invention is to reduce the mass of the hybrid structure, small transport dimensions, the ability to float and raise the floating craft.

This technical result is ensured by the design of the proposed hybrid modular floating craft based on collapsible block modules, characterized by the fact that it includes an upper deck and a bottom, equipped at the corners with container corner fasteners - fittings and along the perimeter - bolting nodes for vertical posts and posts of fastening locks block -modules, as well as diagonal braces, while in the inner volume of the block-modules, insert sealed pneumatic elastic tank-cylinders are installed to ensure the buoyancy of the hybrid block-module.

- It is desirable that the hybrid modular craft contains a wall of the perimeter of the craft, made of sheet material with pre-installed racks of locks for fastening block modules.

- Optionally, pneumatic tank-tanks are fixed on the surface of the upper deck using a cable or rope or a sling through the eyelets of the upper skirt of the tank-tank.

- The fastening lock includes a fastening rack, figured groove plates for fixing the clamping plates and the swivel swivel plate, an eye ring, as well as a conical thrust half-sleeve for lower fixation of the conical stop of the locking mechanism.

Further, the solution is explained by references to the figures, which are shown:

- Insert sealed pneumatic elastic tank-cylinders (7) to ensure the buoyancy of the hybrid block module (21), equipped with a skirt (8) mechanically attached to the inner plane of the deck and an air supply / release valve (9).

The device (Fig. 2a, 2b) contains:

- The wall (10) of the perimeter of the vessel, made in the factory by welding from a steel profile and a steel sheet (or polymer / composite sheet / profile) with pre-installed racks of fastening locks (4) of block modules (21).

- The lock-fastening (4) includes a rack (11) of the lock-fastening, figured plate-grooves (12) for fixing the tension plates (13) and the swivel plate (18) of the swivel (17), the locking plate of the swivel of the locking mechanism (14 ), an eye ring (19), as well as a tapered thrust half-sleeve (16) for lower fixation of the tapered stop (20) of the locking mechanism (15).

- The device (Fig. 4) contains:

- plan view - floating craft (22) assembled from hybrid collapsible block modules (21);

Stacked by 4-5 pcs. in a stack, block modules (21) in disassembled form are delivered to the place of assembly of the floating craft by road, rail, river / sea or air transport.

In a stack, the disassembled block modules (21) are interconnected and fixed to the cargo platforms using standard container corner fasteners-fittings (2).

To assemble block modules (21), the lower platform - the bottom (6) is placed on a flat area.

In the nodes (grooves) of bolting of vertical struts (3) and struts of fastening locks (4) of block modules (21), vertical struts (3), struts of fastening locks (4) as well as diagonal transverse and longitudinal braces are installed and fixed with a bolt tie (five).

After assembling the lower platform-bottom (6) with vertical (pillars 3, 4) and diagonal elements (5), the upper platform-deck (1) is hung out above the bottom (6) by means of a crane beam for the corner fittings, lowered onto the vertical elements ( racks 3, 4), after which it is fixed on them with a bolt tie. Diagonal braces rise and are also fixed on the upper deck attachment points (1).

The fully assembled frame of the block module (21) contains pneumatic tanks (7) and is fixed on the surface of the upper deck platform (1) using a cable (rope, slings) through the grommets of the upper skirt (8).

After assembling the number of block modules (21) required to start the installation of the floating craft (22), the pneumatic tanks (7) are partially filled with air to ensure positive buoyancy of the block modules (21) and the assembly of the floating craft (22).

With the help of a crane, the fully assembled block modules (21) are lowered into the water and connected to each other along the longitudinal and end sides using a locking mechanism (15). In this case, individual block modules (21) are pulled to each other and adjusted manually using ropes passed through the corner fittings (2) of the upper platform - deck (1) during installation.

After aligning the racks of the module fastening locks (4), the locking mechanism (15) is installed in the formed groove and is fixed by turning the swivel (17) by 45 ° using the lever of the locking mechanism pushed through the eyebolt (15).

After assembling all modules (21) of the floating craft (22) together, along the outer perimeter, external walls (10) are installed by combining the racks of the fastening locks (4) of the block modules (21) with the racks of the fastening locks (4) of the outer walls (10 ).

After aligning the racks of the lock-fastening modules (4) and the racks of the lock-fastening of the outer walls (10), the lock mechanism (15) is installed in the formed groove and is fixed by turning the swivel (17) by 45 ° using a lever pushed through the eye ring (19) locking mechanism (15).

After the completion of the assembly of the floating craft (22), through the air supply / release valves (9), the tank cylinders (7) are filled with compressed air along the hose from the compressor to the operating pressure (0.5-2 Atm.). The filling amount can be adjusted, depending on the need, for example, the cylinders can be lowered to reduce the loading height.

Implementation of the declared floating craft in the form of a hybrid module, i.e. a metal collapsible frame with attachment points in conjunction with inset sealed pneumatic elastic cylinders-tanks, provides a decrease in the weight of the entire structure, small transport dimensions, as well as the ability to inflate and inflate the floating craft for lifting and lowering.
