Description

Technical Field

[0001] This invention relates to the field of marine technology, and in particular to an installation structure for a marine cryogenic container. Background Technology

[0002] Currently, cryogenic containers on ships, such as LNG fuel tanks, generally use pads for heat conduction between the mounting base and the hull structure. This is to protect the hull structure from cryogenic damage in the event of tank insulation failure leading to low surface temperatures of the tank and mounting base.

[0003] Current installation structures for cryogenic containers, such as the structure of a cylindrical container for transporting cryogenic liquefied gas on a ship disclosed in Chinese patent CN101473163A, specifically disclose a saddle structure to provide sufficient strength for the installation of the cryogenic container, but it cannot solve the problem of cryogenic container leakage damaging the ship's hull structure. Summary of the Invention

[0004] The purpose of this invention is to provide an installation structure for a ship cryogenic container that can collect cryogenic leaks and effectively prevent them from contacting the ship's hull structure, thereby protecting the hull structure.

[0005] To achieve the above objectives, the present invention provides an installation structure for a ship cryogenic container, comprising: Two saddles are provided for supporting the cryogenic container. Each saddle has a first vent at its bottom and a first temperature sensor is provided at its bottom. The receiving groove is fixedly connected to the two saddles at both ends. The bottom of the receiving groove has a second vent, and the bottom of the receiving groove is provided with a second temperature sensor. The recycling assembly includes a first branch pipe, a second branch pipe, a main pipe, and a recycling tank. The first branch pipe has two sections, each connected to a first vent port of one of the two saddles. A first vent valve is installed on each of the first branch pipes. The second branch pipe is connected to a second vent port of the receiving trough. A second vent valve is installed on the second branch pipe. The first branch pipe and the second branch pipe are connected to the recycling tank through the main pipe. The first temperature sensor is connected to the first relief valve via signal connection, and the second temperature sensor is connected to the second relief valve via signal connection.

[0006] In some embodiments, a third temperature sensor is included, which is mounted on the surface of the cryogenic container and is signal-connected to both the first vent valve and the second vent valve.

[0007] In some embodiments, the saddle includes a saddle groove and a first upright plate fixed to the saddle groove, the first vent is located at the bottom of the saddle groove, the upper part of the first upright plate has a groove, and the cryogenic container abuts against the groove.

[0008] In some embodiments, the saddle further includes a plurality of second upright plates, the second upright plates being fixed to the saddle groove, each of the second upright plates being perpendicular to the first upright plate, and the upper part of the second upright plate being flush with the upper part of the first upright plate.

[0009] In some embodiments, the height of the saddle groove is equal to the height of the receiving groove.

[0010] In some embodiments, the receiving groove has a partition with a connecting hole.

[0011] In some embodiments, two pads are included, and the two saddles are mounted on the hull via the two pads.

[0012] In some embodiments, the pad includes a first epoxy resin layer, a fiberglass layer, and a second epoxy resin layer connected in sequence.

[0013] In some embodiments, the first branch pipe is located below the saddle, the second branch pipe is located below the receiving groove, the main pipe is located below the first branch pipe and the second branch pipe, and the recycling tank is located below the main pipe.

[0014] In some embodiments, the first relief valve and the second relief valve are solenoid valves or electric valves.

[0015] This invention provides an installation structure for a ship cryogenic container, which has the following advantages compared to the prior art: Two saddles support the cryogenic container. Each saddle has a first vent at its bottom and a first temperature sensor at its bottom. A receiving groove is fixedly connected to both saddles at both ends and has a second vent at its bottom, also equipped with a second temperature sensor. The recovery assembly includes a first branch pipe, a second branch pipe, a main pipe, and a recovery tank. Two first branch pipes are connected to the first vents of the two saddles, respectively. Each first branch pipe is equipped with a first vent valve. The second branch pipe is connected to the second vent of the receiving groove and is equipped with a second vent valve. The first and second branch pipes are connected to the recovery tank via the main pipe. The first temperature sensor is signal-connected to the first vent valve, and the second temperature sensor is signal-connected to the second vent valve. Thus, when the first and second temperature sensors detect a leak in the cryogenic container, they generate signals to open the first and second vent valves, allowing the cryogenic leak to be collected in the recovery tank. This effectively prevents the leaked material from contacting the ship's structure, thereby protecting the ship's structure. Attached Figure Description

[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0022] It should be understood that in the description of this application, the terms "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used solely for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. That is, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Furthermore, unless otherwise stated, "a plurality of" means two or more.

[0023] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0024] like Figures 1-4 As shown, the installation structure of a ship cryogenic container according to some embodiments of the present invention includes a saddle 1, a receiving groove 2, and a recovery assembly 3.

[0025] Two saddles 1 are used to support the cryogenic container 4. Each saddle 1 has a first vent at its bottom and a first temperature sensor 11 is installed at its bottom. When a leak occurs, the cryogenic leaked material collected by the saddles 1 and falling from the cryogenic container 4 is discharged from the first vent.

[0026] The two ends of the receiving trough 2 are fixedly connected to two saddles 1. The bottom of the receiving trough 2 has a second vent, and a second temperature sensor 21 is installed at the bottom of the receiving trough 2. When a leak occurs, the low-temperature leaked material collected by the receiving trough 2 from the low-temperature container 4 is discharged from the second vent.

[0027] The recycling assembly 3 includes a first branch pipe 31, a second branch pipe 32, a main pipe 33, and a recycling tank 34. The first branch pipe 31 has two sections, which are respectively connected to the first vent ports of the two saddles 1. A first vent valve 311 is installed on each first branch pipe 31. The second branch pipe 32 is connected to the second vent port of the receiving groove 2. A second vent valve 321 is installed on the second branch pipe 32. The first branch pipe 31 and the second branch pipe 32 are connected to the recycling tank 34 through the main pipe 33.

[0028] In this embodiment, the first temperature sensor 11 is signal-connected to the first relief valve 311, and the second temperature sensor 21 is signal-connected to the second relief valve 321.

[0029] When a leak occurs, the temperature of the saddle 1 and the receiving groove 2 drops rapidly. At this time, the first temperature sensor 11 is triggered to generate a signal to open the first vent valve 311, and the second temperature sensor 21 is triggered to generate a signal to open the second vent valve 321. In this way, the low-temperature leaked material flows to the main pipe 33 through the first branch pipe 31 and the second branch pipe 32, and is finally collected by the recovery tank 34.

[0030] Based on the above structural design, cryogenic leaks can be collected, effectively preventing them from contacting the ship's structure and thus protecting it.

[0031] like Figure 1 As shown, in some embodiments, a third temperature sensor 41 is included. The third temperature sensor 41 is mounted on the surface of the cryogenic container 4 and is signal-connected to both the first vent valve 311 and the second vent valve 321. Thus, the third temperature sensor 41 facilitates direct detection of leaks in the cryogenic container 4, allowing for direct control of the opening of the first vent valve 311 and the second vent valve 321 to collect the leaked cryogenic material.

[0032] like Figure 3 As shown, in some embodiments, the saddle 1 includes a saddle groove 12 and a first upright plate 13 fixed to the saddle groove 12. A first vent is located at the bottom of the saddle groove 12, and the upper part of the first upright plate 13 has a groove 131, in which the cryogenic container 4 abuts. The shape of the groove 131 fits the surface of the cryogenic container 4 to ensure stable installation of the cryogenic container 4. The saddle groove 12 has a accommodating space to collect cryogenic leaks and allows the cryogenic leaks to be discharged from the first vent.

[0033] like Figure 3 As shown, in some embodiments, the saddle 1 further includes multiple second upright plates 14, which are fixed to the saddle groove 12. Each second upright plate 14 is perpendicular to the first upright plate 13, and the upper part of the second upright plate 14 is flush with the upper part of the first upright plate 13. In this way, the second upright plates 14 can improve the structural stability of the first upright plate 13, and the upper part of the second upright plate 14 abuts against the cryogenic container 4, which helps to increase the stress-bearing area of ​​the cryogenic container 4 and ensures the stable installation of the cryogenic container 4.

[0034] like Figure 1 As shown, in some embodiments, the height of the saddle groove 12 is equal to the height of the receiving groove 2.

[0035] like Figure 4 As shown, in some embodiments, the receiving groove 2 has a partition 22 with communicating holes. The partition 22 can improve the structural strength of the receiving groove 2, while the communicating holes on the partition 22 facilitate the flow of cryogenic leaks, allowing the cryogenic leaks to be discharged from the second vent. like Figure 2 As shown, in some embodiments, two pads 5 are included, and the two saddles 1 are mounted on the hull via the two pads 5. In this way, the pads 5 can isolate the heat conduction between the saddles 1 and the hull, protecting the hull structure from low-temperature damage in the event that the insulation of the cryogenic container 4 fails and the saddles 1 become hot.

[0036] like Figure 2 As shown, in some embodiments, the pad 5 includes a first epoxy resin layer 51, a fiberglass layer 52, and a second epoxy resin layer 53, which are sequentially bonded together. The first epoxy resin layer 51 abuts against the saddle 1, increasing friction, while the second epoxy resin layer 53 abuts against the hull, increasing friction and ensuring structural stability. Furthermore, the first epoxy resin layer 51, the fiberglass layer 52, and the second epoxy resin layer 53 all provide thermal insulation.

[0037] like Figure 1 As shown, in some embodiments, the first branch pipe 31 is located below the saddle 1, the second branch pipe 32 is located below the receiving tank 2, the main pipe 33 is located below the first branch pipe 31 and the second branch pipe 32, and the recovery tank 34 is located below the main pipe 33. This allows cryogenic leaks to flow under gravity from the saddle 1 to the first branch pipe 31, from the receiving tank 2 to the second branch pipe 32, from the first branch pipe 31 and the second branch pipe 32 to the main pipe 33, and from the main pipe 33 to the recovery tank 34, without the need for a pump to extract the cryogenic leaks.

[0038] In some embodiments, the first relief valve 311 and the second relief valve 321 are solenoid valves or electric valves. Specifically, the temperature signals detected by the first temperature sensor 11 and the second temperature sensor 21 are transmitted to the controller, which compares the measured values ​​with the set temperature to control the opening or closing of the first relief valve 311 and the second relief valve 321.

[0039] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
