Description

The invention relates to the technology of shipbuilding and relates to the design of modular building blocks of ships

The purpose of the invention is to reduce the labor intensity of electrical installation work when assembling modular units differently.

The drawing shows schematically modal blocks of the ship's hull with busbars installed in them, an axonometric projection.

The hull of the vessel consists of modular units 1-3, in which busbars 4 are placed, located along the sides above the existing waterline, equipment 5, connecting devices 6, inside. speaker cables 7, routed across the vessel and connected to the bus lines 4, interconnect cables 8, as well as detectors 9 The switching equipment 10 is mounted on the 4 pipelines 4.

The construction of the vessel according to the proposed method is carried out in the following sequence:

When a ship is built, the hulls of modular units 1-3 are made, which are first saturated with two busbars 4, equipment 5 and connecting devices 60 At the installation site of blocks 1-3 and they are laid, they are divided and the intra-block cables 7 are connected. one end of which is connected to the protective switching equipment 10 of the busbar 4, and the other end to the equipment. 5, as well as interconnects. 8 cables as follows. For cables 8, on site of installation of unit 2 with blocks 1 and 3: the unattached 5 to the equipment, the ends are cut, marked, placed in connecting devices. 6, and for Cables 8, blocks 1 and 3 that are not connected to equipment 5, the ends are cut, marked, placed in simulators 9, which are installed in the immediate vicinity of blocks 1-3 for a period of set-up works

Before transporting the blocks to the place of their joining in the immediate vicinity of blocks 1-3, the simulators 9 are connected to the connecting devices 6, they preserve the order of location of the cores set by the simulators, turn on the equipment of 5 blocks for joint operation, carry out adjustment and adjustment works, and then dismantle imitators 9 „

After joining the blocks 1-3, the cables, preserved by the simulators of the pores before the location of the cores, are connected to connecting devices, and the busbars of the blocks are interconnected.

Thus, horizontal and vertical transverse cables 7 are laid in each block from busbars 4, providing equipment with electric power for only one block.

Intracellular. Longitudinal cable cables are not laid, as equipment 5 is connected to busbars 4 by the shortest route. In this case, there is no need for switchboards in modular units, to ensure the selectivity of protection, since all consumers are connected to the busbar 4, and the main switchboard is considerably simplified (there are no cables going to modular units, automatic protection machines and t, D0) to be unified The number of interconnect cables is significantly reduced.

Obviously, the laboriousness of electrical installation is greatly reduced, since the wine lines are part of the ship design, the onboard space is released (switchboards are not mounted, and part of the cable routes are not laid), and each modular unit has an independent power distribution system. At the same time, the survivability of the ship and the level of saturation of the modules during the construction of the vessel are increased. Most cables start and end in a modular unit.

Such an electric power distribution scheme allows a more flexible construction of the vessel, since in the case of modular units being split into smaller modular units, there is no question of rearranging block switchboards.

The sequence of vessel construction after completion of the installation work is as follows.

Modular units with the help of simulators 9, consisting of cables, connecting devices, pipelines, fittings, are connected with equivalents of mechanical and electrical equipment, switching equipment, onshore communications — pipelines, cable network. With the help of cables, pipeline fittings and switching equipment, functionally dependent units are interconnected.

Using emergency protection and test equipment, they verify the correctness of electrical installation and assembly work, set up electromechanical circuits and equipment, using coastal communications or electrical equipment equivalents (load devices, power supplies, stands) and mechanical equivalents as power sources or loads. equipment (all kinds of throttling devices, braking devices, etc.)

Next, the modular units commute for operation, in the case of functionally dependent units for joint operation, and check the operation of the equipment. Then the modular units are disconnected from the technological sets of cables and pipelines, transported to the assembly site, joined and finally tested the equipment, after which the vessel was put into operation,

The use of the proposed method makes it possible to refuse switchboards in modular units, from part of cable routes, from selective protection machines. This allows reducing the cost of electrical work and the weight of cable routes by 20-30%.

The proposed method of building a ship from modular units allows the electrical installation work to start much earlier, since the bus duct is laid even when

86996

to reduce the number of cables, since the trunk and intra-block longitudinal cables are not laid; to reduce the laboriousness of electrical installation work, since the bus ducts are part of the ship design, some cables do not prokad

Partly, the protection circuit breakers and the distribution of the electrical panels are not installed, reduce the number of network circuit breakers, as the selectivity of protection is not needed and all equipment is connected to the bus ducts, save onboard space, as the switchboards in the modular units are not installed and part the cable routes on the ship are not laid, to unify the main switchboards and the ship’s electrical power supply system as a whole, to ensure the flexibility of the ship’s construction, since choke blocks have neobhodk- bridge in reflows switchboards in blocks, paving the data bus in the trunking as part of their structure "
