Description

Technical Field

[0001] The present application relates to the technical field of ship emergency power generation systems, and in particular to a ship emergency power generation combination module, a construction method and a ship engine room. Background Art

[0002] Emergency generators and emergency power distribution systems are key emergency power support facilities for ships. When the main switchboard of the ship encounters emergencies such as power failure or tripping, they can provide power support for key equipment such as emergency lighting, ventilation, steering, fire pumps, etc., to ensure the basic safe operation of the ship. Their configuration and performance are important requirements that must be met in accordance with relevant standards during the ship design phase.

[0003] In the past ship design process, emergency power generation equipment, including emergency generators (emergency power generation body), emergency switchboards (emergency power generation combination panels), emergency transformers, emergency diesel cabinets, emergency fans and other components, were defined as the P stage (segment assembly stage) of the cabin sealing parts, and they needed to be installed in this stage. However, this arrangement exposed many problems during the installation process of the D stage (hull detailed installation stage).

[0004] Specifically, during the D phase, the cable laying operation and the cabin internal insulation construction interfered with each other, which hindered the construction progress. The positioning and installation of the emergency diesel tank also conflicted with the insulation coating of the bulkhead. In order to ensure the smooth submission of the bulkhead insulation installation project, the emergency diesel tank had to be disassembled and assembled twice, which consumed a lot of manpower and time.

[0005] In addition, the wiring of the trunk cables and main distribution switches in the unit module cable laying also interfered with the installation leveling cycle of the emergency power generation equipment. Many factors were intertwined, which eventually caused the production and installation of the emergency power generation equipment to be delayed after the ship was undocking, and the equipment installation integrity was not achieved as scheduled. This further caused the installation inspection and functional debugging cycle of the emergency power generation equipment to be delayed, which in turn had an adverse impact on the functional debugging of other important equipment such as emergency lighting and emergency steering gear, delaying the overall delivery progress and debugging process of the ship. Summary of the invention

[0006] The purpose of the present application is to provide a ship emergency power generation combination module, a construction method and a ship engine room, which integrates the ship emergency power generation equipment, piping and cables to form an integrated unit similar to the ship section form, thereby enabling early assembly and commissioning of the ship emergency power generation system, which helps to improve the overall progress of ship assembly and commissioning.

The watertight door 104 can be pre-opened on the top surface structure 102 as a manhole structure, and then the watertight door 104 that can be opened and closed is installed on the manhole structure as a passage for personnel to enter and exit the cavity structure.

[0033] In one embodiment, if Figure 1 As shown, the emergency power generation equipment at least includes an emergency generator 2, an emergency switchboard 3, an emergency diesel tank 4 and an emergency transformer 5. A plurality of equipment bases 11 are installed on the bottom structure 101, and the emergency generator 2, the emergency switchboard 3, the emergency diesel tank 4 and the emergency transformer 5 are fixedly installed on the equipment base 11.

[0034] In one embodiment, if Figure 1 As shown, the ventilation device includes an emergency fan 6 and an electric shutter 8.

The electric shutter 8 is installed on the side wall structure 103 and close to the emergency generator 2, and can release the heat generated in the internal space to the outside when the emergency generator 2 is driven.

[0035] In one embodiment, a plurality of cable brackets (not shown in the figure) and a plurality of pipe brackets (not shown in the figure) are integrated and installed on the bottom surface structure 101 and / or the side wall structure 103. The pipe brackets are used to install and fix the fuel pipe system 9, and the cable brackets are used to install and fix the cables 10. The emergency diesel tank 4 is connected to the emergency generator 2 through the fuel pipe system 9, the emergency generator 2 is connected to the emergency switchboard 3 through the cable 10, and the emergency switchboard 3 is connected to the emergency transformer 5 through the cable 10.

[0036] In one embodiment, if Figure 1 As shown, the ship emergency power generation combination module can also include a load cabinet 12, which is located outside the cavity structure and installed on the side wall structure 103. The emergency distribution board 3 is electrically connected to the load cabinet 12 through the cable 10 passing through the cabin penetration piece, and the load cabinet 12 is used to connect the load.

[0037] In one embodiment, if Figure 1 As shown, a side wall structure 103 of the cavity structure is reserved with a welding structure 106 for welding with other hull structures. The welding structure 106 can be a steel plate structure extending integrally along one side of the side wall structure 103, or a plurality of protrusions can be provided as the welding structure 106.

[0038] The embodiment of the present application also provides a ship engine room, including the aforementioned ship emergency power generation combination module, an emergency power generation installation position is provided in the engine room, and the ship emergency power generation combination module is hoisted to the emergency power generation installation position and then welded and fixed.

[0039] The present application also provides a method for constructing the aforementioned ship emergency power generation assembly module, comprising the following steps:

[0040] During the ship segment platform assembly stage, the ship emergency power generation module is assembled, including structural assembly, pipeline laying and cable laying; structural assembly is to splice and weld the bottom surface structure 101, the top surface structure 102 and the side wall structure 103 to form a cavity structure, and then install skylights, watertight doors, etc., and then hoist the emergency power generation equipment into the cavity structure for installation and fixation, lay the relevant fuel pipe system, lay cables, etc.;

[0041] After the ship emergency power generation module is assembled, the structural inspection and functional debugging are carried out; the structural inspection mainly checks whether the equipment is installed firmly, whether the fuel pipe system is installed correctly and without leakage, whether the cable is laid correctly, etc.; the functional inspection mainly tests the relevant electrical equipment to ensure the normal function of each function;

[0042] The ship is assembled in sections, and then the ship emergency power generation combination module is hoisted to the predetermined position of the engine room section for welding and fixing.

[0043] Among them, the thermal insulation and insulating wrapping operation has been completed before the ship's emergency power generation combination module is hoisted to the predetermined position of the engine room section for welding and fixing.

[0044] In summary, the technical solution of the ship emergency power generation combination module of the present application systematically solves the problems of process conflicts, secondary disassembly and assembly, and debugging delays in the installation process of traditional ship emergency power generation equipment through modular integrated design and construction process optimization. The core principle is to integrate key equipment such as emergency generators, distribution boards, diesel cabinets, transformers, etc. into an independent cavity structure to form a complete functional unit that can be pre-assembled on a segmented platform. The cavity structure preferably adopts a hexahedral design with the bottom, top and side walls spliced ​​together. The lifting ears on the top support the overall lifting of the equipment after pre-installation. The side wall penetration cables are sealed inside and outside, and the ventilation device (emergency fan + electric shutters) can ensure the heat dissipation requirements of the equipment by adding sensor linkage control.

[0045] This design transfers the cable laying and piping laying of emergency equipment, which were originally scattered in the D stage (detailed hull installation stage), and the outfitting of emergency power generation equipment in the P stage (segment assembly stage), to the B platform stage (segment stage), thus avoiding the mutual interference between the cable laying and insulation construction of the emergency power generation system in the traditional process.

[0046] For example, the fuel pipes and cables are pre-fixed with brackets and functional tests in the cavity structure. After being hoisted to the engine room, only the cavity structure needs to be welded and fixed without further operation, thus eliminating the problem of secondary disassembly and assembly caused by the insulation construction of the bulkhead. In addition, the modular construction method ensures the integrity of equipment installation through structural inspection and functional debugging (such as ventilation system air volume verification and emergency power generation joint debugging test) at the stage of segmented platforms, synchronizes the equipment inspection and load equipment debugging cycle, and ultimately shortens the overall delivery cycle of the ship.

[0047] When the inventor actually applies the technical solution of the present application to the construction of a certain type of ship, the technical solution of the ship emergency power generation combination module of the solution greatly saves the dock mooring test cycle through modular integrated design and construction process optimization, which can reduce the mooring cycle by 4 to 5 days and reduce the expenditure ratio by about 20%.

[0048] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
