Description

Technical Field

[0001] This utility model relates to the field of marine composite hose technology, specifically an enhanced thermal insulation marine composite hose. Background Technology

[0002] Marine composite hoses are pipeline systems specifically designed for transporting fluids such as oil and natural gas in marine environments. The "Reinforced Insulated Marine Composite Hoses" disclosed in patent number "CN206112312U" has solved the technical drawbacks of long-term transport of insulated hoses in high-pressure deep-sea environments, such as easy deformation and low safety factor. However, in practical use, composite hoses with similar structures still have many defects. For example, their cold insulation effect is poor. When the composite hose is used in the low-temperature ocean, the low temperature is conducted to the inside of the hose, and the fluid flow (such as oil and natural gas) will deteriorate, leading to reduced transmission efficiency. Decreased fluid flow may also increase pressure loss within the pipeline, further affecting transmission efficiency. Additionally, the pressure-resistant structure is too simple; when used in deep ocean, the composite hose may deform and collapse due to water pressure. Therefore, we have designed an reinforced insulated marine composite hose to solve these problems. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an enhanced thermal insulation marine composite hose, which solves the problem of poor cold insulation and heat preservation effect leading to poor internal fluid flow when used in low-temperature oceans, as well as the problem of a single reinforced pressure-resistant structure affecting the overall strength when used in deep ocean.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: an enhanced thermal insulation marine composite hose, comprising a tube body mechanism and a thermal insulation mechanism assembled inside the tube body mechanism, wherein the tube body mechanism includes a protective sleeve and an inner guide tube, a reinforcing layer is fixedly installed on the inner wall of the protective sleeve, and support rings are fixedly installed at equal intervals on the inner wall of the protective sleeve; The insulation mechanism includes an insulation cotton sleeve fitted on the outer wall of the inner conduit. An insulation layer is fixedly installed on the outer wall of the insulation cotton sleeve. Four sets of assembly holes are equally spaced inside the insulation cotton sleeve. A heating wire is installed inside each of the four sets of assembly holes. A conductive ring is fixedly installed at one end of the insulation cotton sleeve. One end of each of the four sets of heating wires is fixedly connected to the conductive ring.

[0005] Preferably, multiple sets of annular wires are fixedly installed at equal intervals inside the reinforcing layer, and the annular wires are fixedly connected to each other by reinforcing wires.

[0006] Preferably, a junction plate is fixedly connected to the top of the conductive ring, and an insulating sleeve is fitted on the outer wall of the junction plate.

[0007] Preferably, the outer wall of the protective sleeve is provided with bending grooves at equal intervals.

[0008] Preferably, a quick connector is fixedly installed at one end of the inner conduit, and two sets of operating rods are fixedly installed on the outer wall of the quick connector.

[0009] Preferably, the outer wall of the protective sleeve is coated with an anti-corrosion coating.

[0010] This invention provides an enhanced thermal insulation marine composite hose. Compared with the prior art, it has the following advantages: (1) The enhanced thermal insulation marine composite hose, through the cooperation between the thermal insulation cotton sleeve, the thermal insulation layer and the heating wire, can perform cold insulation and heat preservation work when the composite hose is used in the ocean. When the ocean temperature is low, the heating wire can actively heat the inside of the composite hose, avoiding the situation that the internal fluid flow of the composite hose will be poor when it is used in the low temperature ocean, and ensuring the efficiency of fluid transmission through the composite hose in the low temperature ocean. (2) By combining the reinforcing layer and the support ring, the composite hose can be subjected to double reinforcement and pressure resistance treatment during use. The double reinforcement greatly improves the pressure resistance of the composite hose when used in the deep ocean, avoids or reduces the situation of deformation and crushing of the composite hose due to excessive water pressure when used in the deep ocean, and improves the stability of the composite hose when used in the deep ocean.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 This utility model provides a technical solution: an enhanced thermal insulation marine composite hose, including a tube body 1 and a thermal insulation mechanism 2 assembled inside the tube body 1. The tube body 1 includes a protective sleeve 101 and an inner guide tube 4. A reinforcing layer 3 is fixedly installed on the inner wall of the protective sleeve 101, and support rings 401 are fixedly installed at equal intervals on the inner wall of the protective sleeve 101. The thermal insulation mechanism 2 includes a thermal insulation cotton sleeve 201 sleeved on the outer wall of the inner guide tube 4. A thermal insulation layer 204 is fixedly installed on the outer wall of the thermal insulation cotton sleeve 201. Four sets of assembly holes 203 are opened at equal intervals inside the thermal insulation cotton sleeve 201. A heating wire 202 is installed inside each of the four sets of assembly holes 203. A conductive ring 205 is fixedly installed at one end of the thermal insulation cotton sleeve 201, and one end of each of the four sets of heating wires 202 is fixedly connected to the conductive ring 205.

[0019] Based on the above structural design, this enhanced insulated marine composite hose consists of a hose body 1 and an insulation mechanism 2. The hose body 1 is the fluid transport mechanism, and the insulation mechanism 2 is the thermal insulation and cold insulation mechanism for the composite hose during marine use. Specifically, during operation, the protective sleeve 101 protects the exterior of the composite hose during marine use, ensuring its safety. The inner conduit 4 allows for fluid transport, facilitating fluid transport operations in the ocean. The reinforcing layer 3 provides external support and reinforcement for the composite hose during use, and the support ring 401 provides internal support and reinforcement. Through the external support of the reinforcing layer 3 and the internal support of the support ring 401, the composite hose achieves dual reinforcement and pressure resistance during marine use, significantly improving its performance. To enhance the pressure resistance of the composite hose when used in deep ocean conditions, and to prevent or reduce the risk of deformation and crushing, the insulation sleeve 201 provides external insulation for the inner conduit 4, while the insulation layer 204 blocks external low temperatures. This provides insulation and heat preservation for the fluid inside the inner conduit 4. When the composite hose is used in low-temperature ocean conditions, the heating wire 202 can actively heat the inside of the inner conduit 4. This active heating prevents the fluid flow from decreasing and affecting the fluid transmission efficiency, ensuring the efficiency of fluid transmission in low-temperature ocean conditions. The conductive ring 205 provides power to the heating wire 202, facilitating its heating and heat preservation operation.

[0020] Furthermore, multiple sets of annular wires 302 are fixedly installed at equal intervals inside the reinforcing layer 3, and the annular wires 302 are fixedly connected to each other by reinforcing wires 301. Among them, the annular wires 302 provide rigid support for the reinforcing layer 3, and the reinforcing wires 301 can strengthen the tensile strength, thereby increasing the tensile strength of the composite hose during use and preventing the composite hose from deforming or breaking due to pulling during installation.

[0021] Furthermore, a junction plate 206 is fixedly connected to the top of the conductive ring 205, and an insulating sleeve 207 is fitted onto the outer wall of the junction plate 206. The junction plate 206 facilitates connection of the conductive ring 205 to an external power source, improving the ease of energizing the heating wire 202. The insulating sleeve 207 provides insulation protection for the outer wall of the junction plate 206, ensuring its safety during use.

[0022] Furthermore, the outer wall of the protective sleeve 101 is provided with bending grooves 102 at equal intervals. The bending grooves 102 improve the bending performance of the composite hose during use, making it easier for workers to bend and lay the composite hose according to the actual laying conditions, and improving the convenience of workers in laying and adjusting the composite hose.

[0023] Furthermore, a quick connector 5 is fixedly installed at one end of the inner conduit 4, and two sets of operating levers are fixedly installed on the outer wall of the quick connector 5. The quick connector 5 can be connected to an externally compatible connector, thereby facilitating the quick connection and disconnection of the composite hose. The operating levers make it easier for workers to operate the quick connector 5 during installation, improving the convenience of workers when installing and connecting the composite hose.

[0024] Furthermore, the outer wall of the protective sleeve 101 is coated with an anti-corrosion coating 103. The anti-corrosion coating 103 increases the corrosion resistance of the outer wall of the protective sleeve 101, isolates corrosive substances in seawater, increases the oxidation resistance of the composite hose surface, and extends the service life of the composite hose when used in the ocean.
