[0002] The application of floating hoses is becoming more and more extensive in the development and transportation of marine resources, especially in the fields of oil and natural gas extraction and submarine cable laying. As an important transmission channel connecting offshore platforms with ships, shore-based or submarine facilities, the stability and reliability of floating hoses are directly related to the safe and efficient operation. In the design of traditional marine floating hoses, although various measures have been taken to ensure that the hoses can remain afloat in complex marine environments, there are still some challenges.

[0003] In the prior art, hoses without built-in floating airbags usually rely on the buoyancy material of the tube body itself or the addition of external floats to maintain the floating state. However, this type of design has many limitations, such as: the external float is easily affected by the impact of waves and the attachment of marine organisms, resulting in reduced stability; the increase in the weight of the tube body material not only increases the manufacturing cost, but also may affect the flexibility and durability of the hose; in extreme weather or deep-water operating conditions, the floating ability and maneuverability of the hose are often difficult to meet the requirements.

[0016] The beneficial effects of the marine floating hose with high buoyancy provided by the utility model are:

[0017] Compared with the prior art, the utility model provides a marine floating hose with high buoyancy. By arranging a floating airbag inside the hose, the overall buoyancy of the hose can be significantly increased to ensure that the hose remains floating in the water, which is crucial for transporting liquids, especially when operating in open sea or deep water areas, and can prevent damage or operation interruption caused by the sinking of the hose.

DETAILED DESCRIPTION

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by this embodiment more clearly understood, this embodiment is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this embodiment and are not used to limit this embodiment.

[0029] Please also read Figures 1 to 3 Now, a marine floating hose with high buoyancy provided by this embodiment is described. In this embodiment, each section of the marine floating hose with high buoyancy includes a hose body 3 and flanges Ⅰ1 and Ⅱ2 respectively arranged at both ends of the hose body 3. The hose body 3 includes a main body 31 and a secondary body 33. The main body 31 forms a receiving space for receiving fluid. The secondary body 33 is wrapped around the outside of the main body 31. The main body 31, the secondary body 33, the flange Ⅰ1, and the flange Ⅱ2 form an oil-retaining interface 32.

[0030] The main body 31 includes, from inside to outside, an inner lining layer Ⅰ311, a cord reinforcement layer Ⅰ313, and a rubber coating layer Ⅰ314, and a metal skeleton layer is arranged inside the cord reinforcement layer Ⅰ313;

[0031] The auxiliary tube body 33 includes, from the inside to the outside, an inner lining layer II331 covering the outside of the main tube body 31, a cord reinforcement layer II332, and a rubber coating layer II333 with a floating layer and a self-inflating leakage warning layer 3334 therein; the floating layer includes a floating airbag 3332 arranged along the axial direction of the hose, and the auxiliary tube body 33 is provided with an air pipeline 4 connected to the floating airbag 3332, and air valves 6 connected to an external air pressure source are respectively provided at both ends of the air pipeline 4.

[0032] The marine floating hose with high buoyancy of the present embodiment can significantly increase the overall buoyancy of the hose by arranging a floating airbag 3332 inside the hose, thereby ensuring that the hose remains floating in the water, which is crucial for transporting liquids, especially when operating in open sea or deep water areas, and can prevent damage or operation interruption caused by the sinking of the hose.

[0033] Based on the overall description of the above structure, an exemplary structure of an ocean floating hose with high buoyancy of this embodiment is shown in the figure.

[0034] A buffer layer I-1 312 is provided between the inner lining layer I 311 and the cord reinforcement layer I 313 in the main body 31; the cord reinforcement layer I 313 includes, from inside to outside, a cord reinforcement layer I-1 3131, a metal skeleton layer I-1 3132, a buffer layer I-2 3133, a metal skeleton layer I-2 3134, and a cord reinforcement layer I-2 3135. The metal skeleton layer I-1 3132, the buffer layer I-2 3133, and the metal skeleton layer I-2 3134 constitute a metal skeleton layer, which further enhances the strength of the main body 31. The cord reinforcement layer I-1 3131 is formed by winding the cord at a winding angle of 40 to 60 degrees on the buffer layer I-1 312; the cord reinforcement layer I-2 3135 is formed by winding the cord at a winding angle of 40 to 60 degrees on the metal skeleton layer I-2 3134; the winding angle can be 50 degrees, etc. The rubber coating layer I 314 is coated on the outside of the cord reinforcement layer I-2 3135.

[0035] Preferably, the material of the inner lining layer I311 is one of nitrile rubber, chloroprene rubber, styrene-butadiene rubber, EPDM rubber, and polyurethane rubber; the material of the buffer layer I-1 312 and the buffer layer I-2 3133 is one of polyester, cotton thread, polyester thread, and polyamide thread mesh cloth; the material of the metal skeleton layer I-1 3132 and the metal skeleton layer I-2 3134 is one of copper-plated steel wire, spring steel wire, and stainless steel wire; the material of the rubber coating layer I314 is one of nitrile rubber, chloroprene rubber, styrene-butadiene rubber, EPDM rubber, and polyurethane rubber; the rubber coating layer II333 is, from inside to outside, rubber coating layer II-1 3331, floating airbag 3332, protective layer 3333, self-expanding leakage warning layer, rubber coating layer II-2 3335; the material of the inner lining layer II 331 is one of nitrile rubber, chloroprene rubber, styrene butadiene rubber, EPDM rubber, and polyurethane rubber; the material of the rubber coating layer II-1 3331 and the rubber coating layer II-2 3335 is one of nitrile rubber, chloroprene rubber, styrene butadiene rubber, EPDM rubber, and polyurethane rubber.

[0036] There are a plurality of floating airbags 3332 arranged in sequence along the axial direction of the hose, and each floating airbag 3332 is divided into an independent chamber by a soft partition 5, and each independent chamber is provided with a valve for inflation and deflation.

[0037] In this embodiment, the floating airbag 3332 is provided to adjust the buoyancy of the hose by inflation or deflation, adapting to different operation requirements and water depth changes, thereby improving the flexibility and application range of the hose system. The floating airbag 3332 is provided as a plurality of independent chambers, so that even if one chamber is damaged and leaks, the other airbags can still keep the hose floating, thereby enhancing the reliability and safety of the system.

[0038] In this embodiment, the floating airbag 3332 is made of nylon or polyurethane. The polyurethane may be thermoplastic polyurethane, which has good elasticity and toughness, and can withstand certain external impacts without being easily broken; at the same time, it can quickly return to its original state even under high compression, thus ensuring the stable floating performance of the airbag.

[0039] Preferably, the soft partition 5 is made of a highly airtight flexible material. Also preferably, the soft partition 5 is made of high-strength polyester fiber, reinforced nylon fabric, or a thin film material with a special coating. These materials can withstand a certain internal and external pressure difference while ensuring airtightness to prevent gas leakage between chambers.

[0040] Generally, in order to ensure air tightness, the connection between the soft partition 5 and the inner wall of the hose or the adjacent floating airbag 3332 is very important. This is usually achieved by high temperature welding, adhesive bonding or special mechanical fasteners (such as sutures plus waterproof tape) to ensure that there is no leakage at the seams under long-term use and various environmental conditions.

[0041] In this embodiment, by evenly arranging multiple buoyancy supports along the axial direction of the hose, it is helpful to provide uniform buoyancy support for the hose, reduce the swing caused by waves, protect the hose from external impact and wear, and also make the hose easier to be towed and manipulated.

[0042] In addition, as a preferred embodiment, a plurality of floating airbags 3332 are arranged along the radial direction of the hose around the outer circumference of the rubber coating layer II-1 3331. The evenly distributed floating airbags 3332 can make the buoyancy distribution of the hose in all directions more balanced, thereby enhancing the stability of the hose on the water surface and reducing rolling or large swinging. At the same time, the evenly distributed floating airbags 3332 may help improve the streamline of the hose, reduce the resistance of the water flow to the hose, and thus reduce the drag force, save energy consumption, and improve the overall operation efficiency.

[0043] In addition, the floating airbags 3332 evenly distributed along the radial direction of the hose can also provide additional structural support for the hose, disperse external forces, and reduce local stress concentration, thereby improving the durability and damage resistance of the hose and extending its service life.

[0044] In this embodiment, in order to ensure that the pipeline is fully protected and supported, a reinforcement layer 3336 is provided between the rubber coating layer II-1 3331 and the protective layer 3333, and the reinforcement layer 3336 is coated on the outside of the floating airbag 3332. Preferably, the reinforcement layer 3336 is made of high-strength fiber material. High-strength fiber material generally refers to synthetic or natural fibers with extremely high strength, wear resistance and modulus, for example, one of aramid fiber, carbon fiber, ultra-high molecular weight polyethylene fiber, and glass fiber.

[0045] The present embodiment is further improved in that a buffer layer II 3337 is provided between the reinforcement layer 3336 and the rubber coating layer II-1 3331 to reduce friction and wear. Preferably, a clamp for fixing the pipeline is provided on the wall of the hose to ensure the fixed position of the floating airbag 3332 inside the hose to prevent the floating airbag 3332 from moving or rotating. A protective cover for protecting the air valve 6 is provided at the end of the hose to avoid impact wear on the part during the laying of the floating hose, which affects the sealing of the gas pipeline 4.

[0046] In addition, in order to detect the air pressure in each floating airbag 3332, in this embodiment, as a preference, a pressure sensor for detecting the air pressure is provided in each floating airbag 3332 to monitor the pressure, temperature and other conditions of each chamber at any time, and transmit the data to the control system wirelessly or wiredly for real-time monitoring and remote operation.

[0047] As a preferred implementation in this embodiment, the self-expanding leakage warning layer 3334 is divided into multiple sections along the long axis direction of the hose and wound with different winding angles; the winding angle of the next section adjacent to the starting section is larger than that of the starting section, and the remaining sections are wound alternately according to this winding angle rule; or, the winding angle of the next section adjacent to the starting section is smaller than that of the starting section, and the remaining sections are wound alternately according to this winding angle rule. In this embodiment, the winding angles of each section of the self-expanding leakage warning layer 3334 are not specifically described, and can be designed according to actual conditions.

[0048] In this way, when a leak occurs in the marine oil hose, the diameter of the marine floating hose will change. At this time, the staff can more intuitively and promptly determine that the oil hose is leaking, and can promptly warn the staff and replace the leaking oil pipeline, thereby reducing more economic losses and waste of resources.

[0049] When the marine floating hose with high buoyancy of the utility model is used, the hose can be inflated after being spread out to reduce the weight of the hose during the spreading process and improve the spreading efficiency. At the same time, the hose in the uninflated state is also convenient for winding and storage. In addition, it can also be directly formed in one piece using an air compressor or other inflation equipment during the processing and forming process.

[0050] A floating airbag 3332 is arranged in the floating hose. Compared with the prior art in which a floating sponge is arranged in the inner layer of the hose, the hose in this embodiment has a lighter overall weight and better floating stability on the sea, thereby improving the overall ease of use of the hose.

[0051] The above description is only a preferred embodiment of the present embodiment and is not intended to limit the present embodiment. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present embodiment shall be included in the protection scope of the present embodiment.
