Abstract
Description
Technical Field
[0001] This utility model relates to fire-resistant containers, and more particularly to a fire-resistant battery compartment for marine box-type power supplies. Background Technology
[0002] As a convenient green energy carrier, containerized power supplies are currently widely used in scenarios such as power propulsion and peak shaving for pure battery-powered and hybrid-powered ships. The lithium iron phosphate batteries used in marine containerized power supplies are classified as Class 9 dangerous goods. Although equipped with safety protection systems such as fire protection, battery management, and temperature control, there is no unified industry standard, and the configuration of safety equipment varies. Due to operational scenarios, factors such as battery defects, overcharging and over-discharging, short circuits, high temperatures, collisions, water ingress, and lightning strikes may cause thermal runaway and fire of lithium batteries, threatening the safety of ships and crew. The container structure of marine box-type power supplies that have been put into operation and are under research and development generally has the following problems: (1) The classification society specifications require that the fire-resistant battery compartment of marine box-type power supplies be fire-resistant on six sides with an A-60 rating, but the existing design schemes generally only achieve five sides with an A-60 rating, namely: front, back, left, right and top. The bottom side often does not meet the A-60 rating fire resistance requirement because it needs to install battery racks; (2) The bottom of traditional marine box-type power supplies uses composite alumina blankets as fire-resistant materials, while box-type power supplies generally use liquid-cooled battery packs. When the coolant leaks, the bottom composite alumina blankets will be soaked in water and lose their fire-resistant function. Summary of the Invention
[0003] Purpose of the utility model: The purpose of this utility model is to provide a marine box-type fire-resistant battery compartment that meets the A60 fire resistance requirements on all six sides.
[0004] Technical solution: The marine box-type fire-resistant battery compartment of this utility model includes a fire-resistant top deck, a fire-resistant bottom deck, a fire-resistant forward bulkhead, a fire-resistant aft bulkhead, a fire-resistant left bulkhead, and a fire-resistant right bulkhead. The surface of the fire-resistant bottom deck is covered with a fire-resistant deck lining layer.
[0005] Preferably, the thickness of the fire-resistant decking layer is not less than 40 mm, and the fire resistance rating is A60.
[0006] Preferably, multiple bottom deck reinforcements are welded below the fire-resistant bottom deck.
[0007] Preferably, the thickness of the fire-resistant bottom plate is not less than 4.5 mm, and the spacing between the reinforcing members of every two bottom plates is equal and not greater than 600 mm.
[0008] Preferably, multiple top deck reinforcement members are welded below the fire-resistant top deck, and the spacing between every two top deck reinforcement members is equal and not greater than 600mm.
[0009] Preferably, the fire-resistant top deck battery compartment side is covered with a composite alumina blanket for decks with a thickness of not less than 30mm.
[0010] Preferably, the fire-resistant front bulkhead and the fire-resistant rear bulkhead battery compartment sides are respectively covered with a composite alumina blanket layer for bulkheads, and the thickness of each composite alumina blanket layer for bulkheads is not less than 20mm.
[0011] Preferably, multiple side bulkhead stiffeners are vertically welded to the surfaces of both the fire-resistant front bulkhead and the fire-resistant rear bulkhead, with the spacing between any two side bulkhead stiffeners being equal and not greater than 600mm.
[0012] Preferably, the fire-resistant front bulkhead and the fire-resistant rear bulkhead are steel bulkheads with a thickness of not less than 4.5 mm.
[0013] Preferably, A60 fireproof doors are symmetrically installed on the fire-resistant left bulkhead and the fire-resistant right bulkhead, and the battery compartment sides of the fire-resistant left bulkhead and the fire-resistant right bulkhead are respectively covered with a composite alumina blanket for the bulkhead.
[0014] Beneficial effects: Compared with the prior art, this utility model has the following advantages: (1) The battery compartment side of the bottom deck is provided with fire-resistant deck covering, so that the battery compartment meets the A60 fire resistance requirement on all six sides, which enhances the safety and reliability of the box power supply; (2) The battery compartment side of the bottom deck is provided with fire-resistant deck covering, and the battery compartment achieves A60 level fire resistance on all six sides through the continuous fire-resistant structure on all six sides, which can solve the problem of bottom fire resistance failure caused by leakage of liquid cooling system in the prior art; (3) The structure of this utility model is simple, the volume and weight are small, and it is easy to construct and maintain, which further improves the safety performance of the box power supply in the transportation and use process and ensures the navigation safety of electric ships.

Detailed Implementation
[0016] The technical solution of this utility model will be further described below with reference to the embodiments.
[0017] like Figure 1-5 As shown, the marine box-type fire-resistant battery compartment of this utility model includes a fire-resistant top deck 1, a fire-resistant bottom deck 2, a fire-resistant forward bulkhead 3, a fire-resistant aft bulkhead 4, a fire-resistant port bulkhead 5, and a fire-resistant starboard bulkhead 6. The surface of the fire-resistant bottom deck 2 is covered with a fire-resistant deck lining layer 21, forming a continuous fire-facing surface. The fire-resistant deck lining on the side of the battery compartment on the bottom deck can solve the problem of bottom fireproofing failure caused by leakage of the liquid cooling system in the prior art.
[0018] The fire-resistant deck lining layer 21 is 40mm thick, with a fire resistance rating of A60, and is applied to the bottom deck battery compartment side using adhesive. The fire-resistant bottom deck 2 is made of steel with a thickness of not less than 4.5mm. Multiple bottom deck reinforcing members 22 are welded below the fire-resistant bottom deck 2, with equal spacing between every two bottom deck reinforcing members 22 and not exceeding 600mm.
[0019] Multiple top deck reinforcing members 11 are welded below the fire-resistant top deck 1, with equal spacing between every two top deck reinforcing members 11 and not exceeding 600mm. A composite alumina blanket layer 12 for decking is laid on the side of the battery compartment of the fire-resistant top deck 1. The composite alumina blanket layer 12 for decking is 30mm thick, and the composite alumina blanket layer for decking forms a continuous fire-facing surface.
[0020] The front fire-resistant bulkhead 3 and the rear fire-resistant bulkhead 4 are each covered with two 20mm thick composite alumina blanket layers 32 for the bulkhead. The composite alumina blanket layers 32 form a continuous fire-facing surface.
[0021] Multiple side bulkhead stiffeners 31 are vertically welded to the surfaces of both the fire-resistant front bulkhead 3 and the fire-resistant rear bulkhead 4. The spacing between any two side bulkhead stiffeners 31 is equal and not greater than 600mm.
[0022] The fire-resistant front bulkhead 3 and the fire-resistant rear bulkhead 4 are made of steel, and the thickness of the steel bulkhead is not less than 4.5 mm.
[0023] Two A60 fireproof doors 51 are symmetrically installed on the fire-resistant left bulkhead 5 and the fire-resistant right bulkhead 6 respectively. Two layers of 20mm thick composite alumina blanket for the bulkhead are laid on the battery compartment side of the fire-resistant left bulkhead 5 and the fireproof doors 51 together form a continuous fire-facing surface.
[0024] When using, such as Figure 6 The battery compartment 7 described in this utility model is placed inside one side of the container body 8. Figure 6 (Place the container on the right side), and then place it on the ship for use.
[0025] According to classification society regulations, for general-purpose box-type power supplies, the enclosure of the battery compartment should be a Class A60 fire-resistant partition. If the dimensions and structural form of the fire-resistant partition are inconsistent with the Class A standard core in the FTP code, a standard fire resistance test should be conducted; if the strength and stiffness of the fire-resistant partition are equivalent to the standard core, including plate thickness, stiffener dimensions, and spacing, a standard fire resistance test is not required. The marine box-type power supply fire-resistant battery compartment described in this utility model meets the relevant regulatory requirements, therefore a standard fire resistance test is not required.
