DETAILED DESCRIPTION

[0055] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0056] See also Figures 1 to 25 It should be noted that the illustrations provided in this embodiment are only used to illustrate the basic concept of the present invention in a schematic manner, and the illustrations only show the components related to the present invention rather than the number, shape and size of the components in the actual embodiment. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0057] Existing CO 2 The construction mode of the fire extinguishing system has the following specific defects:

[0058] 1. The construction sequence is rigid and lacks flexibility: the existing model requires that all structural work must be completed before CO can be carried out. 2 The installation of the system could not be dynamically adjusted according to the actual production progress of the shipyard, resulting in insufficient resource utilization and extended construction period;

[0059] 2. Low space utilization: The layout of the gas cylinder group and the control box did not fully consider the temporary needs during the construction phase, occupying limited cabin space and affecting the parallel development of other outfitting operations;

[0060] 3. Complexity of multi-task collaborative work: Different professional types of work in CO 2 Frequent cross-operation between systems increases the difficulty of safety management and also leads to low efficiency due to poor communication and coordination;

[0061] 4. Serious waiting phenomenon: Due to the strict sequence dependence between the processes, the delay of the previous process is directly transmitted to the subsequent process, resulting in cumulative delays, which further aggravates the tension of the construction period.

[0062] In view of the above defects, the present application provides a ship carbon dioxide integrated fire extinguishing system and a construction method thereof, which are now described in detail through the following embodiments.

[0063] This embodiment provides a ship carbon dioxide integrated fire extinguishing system, such as Figure 1 As shown, the ship carbon dioxide integrated fire extinguishing system includes a plurality of bottle group frames 100 and module reinforcement components.

[0064] like Figure 2 and Figure 3 As shown, each bottle group frame 100 is provided with a plurality of carbon dioxide gas cylinders 101. A bottle head valve 102 is provided on the top of each carbon dioxide gas cylinder 101. The bottle head valve 102 is used to control the release of the high-pressure gas in the carbon dioxide gas cylinder 101. The bottle head valve 102 is operated mechanically or pneumatically to achieve functions such as gas sealing, release and safe pressure relief. The bottle head valve 102 is connected to the carbon dioxide manifold 110 through a hose 103. Figure 1 As shown, the carbon dioxide collecting pipe 110 is connected with the corresponding area through the pipeline 120, specifically connected with the pipeline of the corresponding area. The corresponding area usually refers to the area where fire may occur, or the area to be extinguished, etc. After the carbon dioxide gas reaches the corresponding area through the pipeline 120, it is sprayed out from the nozzle to extinguish the fire in the corresponding area.

[0065] like Figure 1As shown, a plurality of bottle group frames 100 are connected via a module reinforcement assembly, the module reinforcement assembly includes a first assembly and a second assembly, the tops of adjacent bottle group frames 100 are connected via the first assembly, and the bottoms of adjacent bottle group frames 100 are connected via the second assembly.

[0066] The integrated carbon dioxide fire extinguishing system for ships provided in this embodiment reduces the operating load on the ship and the cross-operation of multiple types of work on the ship through an integrated modular design, so that the outfitting of the ship's carbon dioxide fire extinguishing system is moved forward to the previous process for completion. After the remaining outfitting construction is completed, the relevant equipment and outfitting parts of the ship's carbon dioxide fire extinguishing system can be completed through a single hoisting, thereby avoiding mutual interference between different types of work in the same operating area, greatly improving the shipbuilding efficiency, and shortening the construction period of the carbon dioxide fire extinguishing system.

[0067] In an optional embodiment, if Fig.12 , Fig.13 , Fig.15 and Fig.16 As shown, the first component includes a first angle steel 211 and a cushion block 212. The top edges of adjacent bottle group frames 100 are connected by the first angle steel 211. A cushion block 212 is arranged between the first angle steel 211 and the bottle group frame 100. The first angle steel 211 and the cushion block 212 are connected to the top of the bottle group frame 100 by bolts.

[0068] In an optional embodiment, if Fig.18 As shown, the second component includes a second angle steel 221 , and the bottom edges of adjacent bottle group frames 100 are connected by the second angle steel 221 .

[0069] In an optional embodiment, if Figures 4 to 11 As shown, the second component also includes an angle steel foot 222 and a round steel foot 223. The angle steel foot 222 is provided on the second angle steel 221 in the middle of the edges of two adjacent bottle group frames 100, and the round steel foot 223 is provided on the second angle steel 221 in the middle of the edges of four adjacent bottle group frames 100. The angle steel foot 222 and the round steel foot 223 are both used to support the bottle group frame 100. As a specific implementation, after the bottoms of two adjacent bottle group frames 100 are connected by the second angle steel 221, they are connected to the angle steel foot 222 through the second angle steel 221; after the bottoms of four adjacent bottle group frames 100 are connected by the second angle steel 221, they are connected to the round steel foot 223 through the second angle steel 221. Optionally, in order to facilitate the supply and transportation, the carbon dioxide gas cylinder 101 is pre-installed in the bottle group frame 100 by the manufacturer for supply. In order to ensure stability during transportation, the original foot can be retained during supply, and the bottle group frame 100 is modified during the module assembly operation. In order to facilitate the subsequent on-site welding work, the bottom foot of the bottle group frame 100 is changed to Figures 4 to 11In the form shown, the bottoms of two adjacent bottle group frames 100 are connected by the second angle steel 221 and supported by the angle steel foot 222 ; the bottoms of four adjacent bottle group frames 100 are connected by the second angle steel 221 and supported by the round steel foot 223 .

[0070] In an optional embodiment, if Fig.10 As shown, the second component also includes a bottom channel steel reinforcement 224, which is provided at the middle position inside the bottom of the bottle assembly frame 100, and the bottom channel steel reinforcements 224 provided in adjacent bottle assembly frames 100 are connected to each other. Since the bottom of the bottle assembly frame 100 includes bottom support profiles provided at intervals, the bottom channel steel reinforcements 224 are used to reinforce the bottom support profiles.

[0071] In an optional embodiment, if Figure 1 , Fig.17 and Fig.18 As shown, a channel platform 170 is also provided at the bottom of the bottle group frame 100, and the channel platform 170 is detachably connected to the second angle steel 221. The channel platform 170 is used for maintenance and replacement of the carbon dioxide cylinders 101 and daily passage of the crew. As a specific implementation, the second angle steel 221 is welded to the bottom profile of the bottle group frame 100, and the channel platform 170 is detachably connected to the second angle steel 221 by bolts. In this way, after the ship's carbon dioxide integrated fire extinguishing system is hoisted and positioned, when the bottom foot of the bottle group frame 100 is inconvenient, the channel platform 170 can be temporarily disassembled to ensure normal construction. After the ship's carbon dioxide integrated fire extinguishing system of this embodiment is hoisted, a flower steel plate or a fiberglass grille is laid on the channel platform 170 for people to walk on.

[0072] In an optional embodiment, if Figures 19 to 21 As shown, the tops and bottoms of adjacent bottle group frames 100 are connected by frame channel steel reinforcements 130, that is, the side walls of adjacent bottle group frames 100 are connected by frame channel steel reinforcements 130, and the frame channel steel reinforcements 130 are detachably connected to the bottle group frames 100. The frame channel steel reinforcements 130 are temporary reinforcements, and can be removed after the ship carbon dioxide integrated fire extinguishing system of this embodiment is hoisted to ensure the original weight of the ship carbon dioxide integrated fire extinguishing system, and the removed frame channel steel reinforcements 130 can be recycled to save construction costs.

[0073] like Figures 19 to 21 As shown, the frame channel steel reinforcement 130 is provided with four lifting eye plates 140 at the hard stop corresponding to the bottle group frame 100, and the lifting eye plates 140 are arranged opposite to each other. The lifting eye plates 140 are used for lifting the ship's carbon dioxide integrated fire extinguishing system. It can be understood that the selection of the lifting eye plates 140 can be selected according to the total weight of the ship's carbon dioxide integrated fire extinguishing system and the corresponding coefficient of lifting calculation.

[0074] In an optional embodiment, if Figure 1 As shown, a pipe support 150 is provided on the top of the bottle assembly frame 100, and the pipe support 150 is used to fix the pipeline 120. As a specific embodiment, the pipe support 150 is connected to the top profile of the bottle assembly frame 100 by welding to form an integrated design.

[0075] A top brace 160 is provided at the top edge of the bottle assembly frame 100. After the ship carbon dioxide integrated fire extinguishing system is hoisted, the top brace 160 can be welded to the ship bulkhead to further support, reinforce and prevent the ship carbon dioxide integrated fire extinguishing system from tipping over.

[0076] In an optional embodiment, if Figure 2 As shown, a plurality of carbon dioxide gas cylinders 101 are arranged in each cylinder group frame 100 , and a fixing member 104 is arranged on both sides of each adjacent carbon dioxide gas cylinder 101 , and the fixing members 104 on both sides are clamped and fixed by bolts 105 .

[0077] In an optional embodiment, if Figure 1 , Fig.19 and Fig. 22 As shown, a carbon dioxide gas control box 300, a delay control box 400, a carbon dioxide fire extinguishing system relay box 500, a key box 600 and a carbon dioxide fire extinguishing system nameplate 700 are provided on the bottle group frame 100. The sizes, installation positions and bolt hole spacings of the above-mentioned equipment are pre-installed with corresponding profiles and bolt holes are provided. Each control box, nameplate, etc. are fixed to the bottle group frame 100 by bolt connection, forming a highly integrated one-piece combination design with the bottle group frame 100.

[0078] Among them, the carbon dioxide gas control box 300 is a device for controlling and monitoring the release of carbon dioxide gas, which usually includes components such as a starter gas cylinder and a control valve. Its main function is to ensure that carbon dioxide can be released accurately and timely for fire extinguishing when a fire occurs. It may also include pressure monitoring and alarm functions; the delay control box 400 is used to delay the release of carbon dioxide for a certain period of time after the fire occurs. This delay is to ensure that people have enough time to evacuate the dangerous area. It usually includes a mechanical delayer or other delay device; the carbon dioxide fire extinguishing system relay box 500 is a device for controlling and transmitting electrical signals. In the carbon dioxide fire extinguishing system, it can be responsible for receiving signals from fire detectors and triggering corresponding operations, such as starting valves or alarms. It can also be integrated with other control systems to achieve automated operation; the key box 600 is usually used to store keys or other important tools for starting or shutting down the carbon dioxide system. It is located in a key position to ensure that only authorized personnel can access and control the key components of the system; the carbon dioxide fire extinguishing system nameplate 700 is an identification plate installed on the equipment to provide key information, such as equipment name, model, production date, operating instructions, etc., and also includes safety warnings and instructions for use. The carbon dioxide gas control box 300, the time delay control box 400, the carbon dioxide fire extinguishing system relay box 500, the key box 600 and the carbon dioxide fire extinguishing system nameplate 700 are all commercially available.

[0079] In an optional embodiment, the top profile of the bottle group frame 100 is a porous angle steel, which is used to fix and bind the direction pipe 180 of the control gas.

[0080] like Fig.23 As shown, the working process of the ship carbon dioxide integrated fire extinguishing system provided by this embodiment is roughly as follows: during the daily navigation of the ship, the real-time status on board is monitored by gas and temperature. When a fire occurs, the ship's alarm system starts to alarm, and the delay control box 400 in the ship's carbon dioxide integrated fire extinguishing system starts to work and ensures that personnel in the fire area are evacuated and all vents and hatches in the fire area are closed. Then, the carbon dioxide gas control box 300 starts to work, controls the carbon dioxide cylinder 101 to pneumatically open, the pneumatically controlled release valve 800 to pneumatically open, and the bottle head valve 102 in the carbon dioxide cylinder 101 to open. The carbon dioxide gas enters the carbon dioxide collecting pipe 110 through the flexible tube in the carbon dioxide cylinder 101 and then reaches the nozzle in the corresponding area through the pipeline 120 and is sprayed out, quickly filling the area and implementing fire extinguishing.

[0081] This embodiment also provides a method for constructing a ship carbon dioxide integrated fire extinguishing system, comprising the following steps:

[0082] S100, providing a plurality of bottle group frames 100, each of which is provided with a plurality of carbon dioxide gas cylinders 101;

[0083] S200, connecting a plurality of bottle group frames 100 through a module reinforcement assembly, wherein the module reinforcement assembly includes a first assembly and a second assembly, connecting the tops of adjacent bottle group frames 100 through the first assembly, and connecting the bottoms of adjacent bottle group frames 100 through the second assembly;

[0084] S300, connecting the bottle head valve 102 of the carbon dioxide gas cylinder 101 with the hose 103; after the carbon dioxide manifold 110 is positioned, connecting the hose 103 with the carbon dioxide manifold 110, and connecting the carbon dioxide manifold 110 with the pipeline 120;

[0088] S700. Lift the ship's carbon dioxide integrated fire extinguishing system to the ship's installation area.

[0089] Among them, step S200 includes modifying the foot of the carbon dioxide gas cylinder 101, specifically including the bottom of two adjacent bottle group frames 100 connected by the second angle steel 221 and supported by the angle steel foot 222; the bottom of four adjacent bottle group frames 100 are connected by the second angle steel 221 and supported by the round steel foot 223.

The first angle steel 211, the frame channel steel reinforcement 130, the bottom channel steel reinforcement 224, the lifting eye plate 140 and other welded parts are installed first, and after the welding operation is completed, the remaining iron outfitting parts mentioned above are installed one by one.

[0090] Step 300 specifically includes: first, connecting the hose 103 to the bottle head valve 102, and after completing the positioning of the carbon dioxide collecting pipe 110, connecting the hose 103 to the carbon dioxide collecting pipe 110, and then positioning and installing each pipe section of the pipeline 120 one by one. After the positioning is completed, the branch pipes of each carbon dioxide collecting pipe 110 are connected to the branch pipes of the pipeline 120. The carbon dioxide collecting pipe 110 needs to be adjusted to cooperate with the positioning of the pipeline 120. After the adjustment and connection are completed, the carbon dioxide collecting pipe 110 and the main pipe of the pipeline 120 are fixed, and finally the air-controlled release valve 800 and the pressure gauge, pressure switch and other pipe accessories are installed.

[0091] Between step 300 and step 400, the following steps are also included: after the outfitting of the entire functional module is completed, the welding parts are polished, and after the welding points are polished, the entire module is painted.

After the equipment installation is completed, the laying of the direction pipe 180 is completed.

[0093] After step 400 and before step S500, the process also includes tightness and flow tests. At this point, the ship carbon dioxide integrated fire extinguishing system (also known as carbon dioxide integrated functional module) is completed in the workshop. Construction in the workshop provides a large construction space, a comfortable construction environment, and high construction efficiency.

[0094] Step S500 specifically includes: using the workshop's driving crane to test lift the ship's carbon dioxide integrated fire extinguishing system, ensuring that the welding of each lifting eye plate 140 is correct before starting the test lifting, confirming that there is no yield deformation at the welding of the lifting eye plate 140, and there is no obvious visual deformation of the functional module profile structure before formal lifting, and the construction unit can add temporary reinforcement according to the actual situation.

[0095] While completing step 100 to step S600, the dock simultaneously carries out welding of the functional module foot, welding of the protective web, polishing and painting of the deck surface between the carbon dioxide systems, and laying of the deck covering, wherein a space at the functional module foot needs to be reserved when laying the covering.

[0096] Step 700 specifically includes: before completing the hoisting of the ship's carbon dioxide integrated fire extinguishing system, it is necessary to mark and position the installation area according to the construction drawings to assist in the positioning and installation of the functional modules. In this embodiment, the dock is high-lifted based on the lifting eye plate 140 to lift the hook, and the ship's carbon dioxide integrated fire extinguishing system is gradually lowered after being lifted to the designated installation area. The positioning is performed according to the position of the welding protection web of the foot (including the angle steel foot 222 and the round steel foot 223) and the on-site marking position, and finally the foot is accurately dropped to the welding point. After the high-lift wire rope is completely relaxed without force, the hook is withdrawn, and finally the welding between each foot and the web is completed.

[0097] Step S700 also includes grinding and paint repairing the bottom welding parts of the ship's carbon dioxide integrated fire extinguishing system. After the paint repair is completed, the dressing filling at the bottom is completed, and then the grille is laid on the channel platform 170. At this point, the installation of the ship's carbon dioxide integrated fire extinguishing system in this embodiment is completed.

[0098] During the construction process of the ship carbon dioxide integrated fire extinguishing system in this embodiment, all materials and equipment are hoisted using small vehicles in the workshop. Compared with large lifting equipment at the dock or pier, the workshop driving operation cost is low, which saves the lifting resources of large lifting equipment, reduces the lifting cost, avoids cross-lifting operations, and improves the lifting efficiency.

[0099] The ship is hoisted onto the ship by a four-point hoisting method through a high crane at the dock. The hoisting points are arranged with the help of finite element analysis, such as Fig.24 As shown, in the hoisting process of this embodiment, according to Fig.19 Under the arrangement of the hanging points shown, the deformation of the bottle assembly frame 100 is distributed in the range of 0 to 12.938 mm. The deformation of the bottle assembly frame 100 in the middle position is larger due to the shear stress of the hanging, and the maximum deformation is 12.938 mm. The maximum deformation is theoretically elastic deformation and will not cause permanent impact on the bottle assembly frame 100. Fig.25 As shown, during hoisting, the overall stress distribution of the bottle group frame 100 is in the range of 0 to 193 MPa, the main distribution area of ​​the bottle group frame 100 is in the range of 0 to 81 MPa, and the maximum stress in a very small area can reach 193 MPa. The above stress distribution is theoretically within the allowable range, and the stress distribution at the four lifting eye plates 140 is uniform.

Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
