Description

Technical Field

[0001] The utility model relates to the technical field of marine floating hoses, in particular to a floating hose with monitoring and early warning functions. Background Art

[0002] As global energy demand continues to grow, offshore oil extraction and transportation are becoming increasingly important. While traditional methods of crude oil transportation, such as submarine pipelines and fixed platforms, have met this demand to a certain extent, they face numerous limitations in deepwater, harsh marine environments, and operations requiring frequent movement. For example, submarine pipelines are expensive to install and maintain, and difficult to implement in certain waters. Fixed platforms, however, are geographically constrained and lack the flexibility to respond to changing operational needs.

[0003] In order to solve these problems, double-layer marine floating hoses came into being. However, the existing double-layer marine floating hoses still have some significant shortcomings in practical applications. Among them, the problem of flange connection is also a major shortcoming of the existing double-layer skeleton hose. The flange connection design may not be strong enough and prone to leakage. Especially under the influence of wave impact and physical wear, the sealing performance of the connection will be further reduced, increasing the risk of leakage. The mechanical strength of the flange connection may also be insufficient and unable to withstand high pressure and external force, which can easily lead to loosening or damage of the connection, affecting the safety and stability of the entire system. At the same time, when a leak occurs in the flange, the leak is mostly discovered through the expansion of the pipe body, which not only increases the difficulty of handling, but also shortens the time for operation and increases the risk of operation. Utility Model Content

[0004] The purpose of the utility model is to provide a floating hose with monitoring and early warning functions, aiming to improve the overall sealing of the hose and reduce the risk of leakage.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: providing a floating hose with monitoring and early warning functions, comprising a pipe body and flanges provided at both ends of the pipe body, wherein the flanges are bonded to the pipe body;

[0006] The tube bodies are sequentially arranged from the inside to the outside as a first tube body, a second tube body and a floating body, and a buffer layer is formed between the second tube body and the first tube body;

[0007] The flange includes a flange tube inserted into the tube body and a flange plate arranged at the upper end of the flange tube. A sleeve and a rib ring are sequentially arranged on the flange tube along its extension direction. The rib ring is inserted into the first tube body, and the sleeve is inserted into the second tube body. The lower edge of the sleeve abuts against the end of the first tube body, the upper bottom surface of the sleeve abuts against the end of the second tube body, and the upper top surface of the sleeve is flush with the end surface of the floating body.

[0008] The first tube body is sequentially provided with an inner lining layer I, a reinforcement layer I, a metal skeleton layer, a reinforcement layer II and an outer covering layer I from the inside to the outside;

[0009] The second tube body is sequentially provided with an inner lining layer II, a reinforcement layer III and an outer covering layer II from the inside to the outside;

[0010] The floating body is sequentially provided with an appendage layer, a protective layer and an outer covering layer III from the inside to the outside.

[0011] Furthermore, a reinforcement layer is provided between the protective layer and the outer covering layer III.

[0012] Furthermore, the diameter of the upper edge of the sleeve is larger than the diameter of the lower edge.

[0013] Furthermore, the sleeve includes a tube body and a baffle arranged at the upper end of the tube body. The tube body is inserted into the second tube body, and the lower end of the tube body abuts against the end of the first tube body. The lower end of the baffle abuts against the end of the second tube body, and the upper end is flush with the floating body.

[0014] Furthermore, ribs are provided on the cylinder body in a direction perpendicular to the axis thereof and are press-fitted with the second tube body.

[0015] Furthermore, a winding steel wire group II is provided in the second tube body at the interval between the blocking piece and the cylinder body.

[0016] Furthermore, a plurality of rib rings are spaced apart along the extension direction of the flange tube, and at least the rib ring close to the lower end of the flange tube has a wedge-shaped surface inclined toward the upper end of the flange tube.

[0017] Furthermore, a winding steel wire group I is provided in the first tube body at the interval between each two adjacent tendon rings.

[0018] Furthermore, the flange is provided with a leak detector for detecting crude oil leakage, and the leak detector is located in the buffer layer.

[0019] The beneficial effects of the floating hose with monitoring and early warning functions provided by the utility model are:

[0020] Compared to existing technologies, the present invention provides a floating hose with monitoring and early warning functions. It consists of a tube body and flanges at both ends. The flanges are bonded to the tube body, ensuring a tight and reliable connection. The hose body adopts a multi-layered design, consisting, from the inside out, of a first tube body, a second tube body, and a floating body. A buffer layer is formed between the second and first tube bodies, effectively absorbing external impact forces and reducing the impact on the internal tube body, thereby improving overall safety and service life.

[0021] The flange consists of a flange sleeve inserted into the tube body and a flange plate mounted on the upper end of the flange sleeve. The flange sleeve is provided with a sleeve and a rib ring along its extension. The rib ring is inserted into the first tube body, while the sleeve is inserted into the second tube body. This design not only strengthens the connection between the flange and the tube body, but also ensures a tight fit at the connection. Specifically, the lower edge of the sleeve abuts the end of the first tube body, the bottom surface of the upper edge abuts the end of the second tube body, and the top surface of the upper edge is flush with the floating body, forming a stable mechanical connection.

[0022] Furthermore, the design of the rib ring further enhances the stability of the connection. Particularly near the lower end of the flange, the rib ring features a wedge-shaped surface that slopes toward the upper end of the flange. This helps to better distribute stress and prevent connection failure due to external forces. The sleeve design has also been optimized, with a larger diameter at the top than at the bottom, creating a tapered structure. This allows the sleeve to fit more tightly against the pipe at the connection, improving the sealing and stability of the connection.

[0023] The outermost float ensures the hose's stable buoyancy, making it suitable for offshore operations. This design not only facilitates hose installation and maintenance, but also reduces operational complexity and improves efficiency. The hose's multi-layered structure, buffer layer, and sophisticated flange connection design all work together to ensure high performance in high-risk, demanding applications.

[0030] 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 intended to limit this embodiment.

[0031] Please also refer to Figures 1 to 3 The floating hose with monitoring and early warning functions provided by this embodiment is now described. The floating hose with monitoring and early warning functions of this embodiment includes a pipe body and flanges 5 provided at both ends of the pipe body, and the flanges 5 are bonded to the pipe body.

[0032] The tube bodies are sequentially arranged from the inside out into a first tube body 1, a second tube body 2, and a floating body 3, with a buffer layer 4 formed between the second tube body 2 and the first tube body 1. Furthermore, the flange 5 comprises a flange barrel 51 inserted into the tube body and a flange plate 52 disposed at the upper end of the flange barrel 51. A sleeve 511 and a rib ring 512 are sequentially arranged on the flange barrel 51 along its extension direction. The rib ring 512 is inserted into the first tube body 1, and the sleeve 511 is inserted into the second tube body 2. The lower edge of the sleeve 511 abuts against the end of the first tube body 1, the upper bottom surface of the sleeve 511 abuts against the end of the second tube body 2, and the upper top surface of the sleeve 511 is flush with the end surface of the floating body 3.

[0033] In this embodiment of a floating hose with monitoring and early warning functions, the buffer layer 4 between the second tube body 2 and the first tube body 1 reduces the impact of external shocks on the tube body, improving safety. Furthermore, the adhesive connection between the flange 5 and the tube body ensures a tight and reliable connection, while the design of the rib ring 512 and sleeve 511 enhances the strength of the connection.

[0034] Based on the overall description of the above structure, an exemplary structure of a floating hose with monitoring and early warning functions in this embodiment is as follows: Figure 1 As shown in the figure, the first tube body 1 is sequentially provided with an inner lining layer I 11, a reinforcement layer I 12, a metal skeleton layer 13, a reinforcement layer II 14, and an outer covering layer I 15. The second tube body 2 is sequentially provided with an inner lining layer II 21, a reinforcement layer III 22, and an outer covering layer II 23. The floating body 3 is sequentially provided with an appendage layer 31, a protective layer 32, and an outer covering layer III 33.

[0035] The inner lining layer I 11 and the inner lining layer II 21 are made of one of nitrile rubber, chloroprene rubber, styrene-butadiene rubber, EPDM rubber, or polyurethane rubber. These materials are oil-resistant, ensuring the seal and corrosion resistance of the internal conveying medium. The metal skeleton layer 13 is made of one of copper-plated steel wire, spring steel wire, or stainless steel wire. This not only enhances the mechanical strength of the hose but also provides a conductive path for facilitating the wiring of the leak detector 6. The outer covering layers I 15, II 23, and III 33 are made of one of nitrile rubber, chloroprene rubber, styrene-butadiene rubber, EPDM rubber, or polyurethane rubber. The inner appendage layer 31 of the float 3 is made of one of expanded polyethylene foam, polyurethane sponge, or natural rubber sponge.

[0036] Preferably, a reinforcement layer 34 is provided in the middle of the tube body and between the protective layer 32 and the outer covering layer III 33 to effectively limit external deformation, protect the floating body 3 from damage, and extend the service life.

[0037] A further improvement of this example is that, referring to Figure 1 As shown in FIG, the length of the first tube body 1 is smaller than the length of the second tube body 2. Such a configuration has a better protective effect on the first tube body 1. Specifically, it is embodied in:

[0038] First, the longer second tube 2 provides additional external protection for the inner first tube 1. This structure effectively resists wave impact and physical wear in harsh marine environments, thereby reducing damage to the first tube 1. Furthermore, the buffer layer 4 formed between the second tube 2 and the first tube 1 absorbs some of the energy from external forces, further protecting the internal pipeline.

[0039] Secondly, from the perspective of structural strength, the longer second tube body 2 helps improve the rigidity and pressure resistance of the entire hose. More material is used for support and reinforcement, making the hose more stable and reliable when subjected to high pressure and external forces. In particular, at the connection between the flange 5 and the tube body, the second tube body 2 is longer than the first tube body 1. This allows the sleeve 511 to be better secured within the second tube body 2, enhancing the sealing and mechanical strength of the connection between the flange 5 and the tube body, and ensuring the reliability of the connection.

[0040] In terms of installation and maintenance, the shorter first tube 1 makes the flange 5 connection more compact, facilitating positioning and adjustment during installation and simplifying on-site construction operations. Furthermore, when inspection or maintenance is required, the longer second tube 2 can be more easily removed and reinstalled without exposing or damaging the internal first tube 1, improving maintenance convenience.

[0041] Finally, considering buoyancy, the longer second tube 2 better cooperates with the float 3, allowing the hose to maintain a stable floating state on the water surface. This design helps the hose maintain good operational performance during offshore operations, ensuring its efficient operation in complex marine environments.

[0042] As a further improvement to this embodiment, flange ears 521 are provided at the ends of flange barrel 51 to facilitate connection with external components. A sleeve 511 is also designed along the flange barrel 51, near flange ears 521, along its extension direction. The diameter of the upper edge of sleeve 511 is larger than that of the lower edge. This design allows sleeve 511 to better fit the pipe body at the connection point, improving the sealing and stability of the connection.

[0043] Specifically, refer to Figures 1 to 3 As shown in the figure, the sleeve 511 includes a tube body 5112 and a baffle 5111 arranged at the upper end of the tube body 5112. The tube body 5112 is inserted into the second tube body 2, and the lower end of the tube body 5112 abuts against the end of the first tube body 1, the lower end of the baffle 5111 abuts against the end of the second tube body 2, and the upper end is flush with the floating body 3.

[0044] Among them, the diameter of the baffle 5111 is larger than the diameter of the cylinder body 5112, thereby forming a step-like shape between the baffle 5111, the cylinder body 5112 and the flange cylinder 51, so as to facilitate connection with the first tube body 1 and the second tube body 2 respectively, thereby improving the connection stability and sealing.

[0045] Specific as Figure 1As shown, the stepped space formed by the baffle 5111 and the tube body 5112 is connected to the second tube body 2, and the stepped space formed between the tube body 5112 and the flange tube 51 is connected to the end of the first tube body 1. The lower end of the flange tube 51 is inserted into the first tube body 1 and connected to the first tube body 1. Preferably, the lower end of the flange tube 51 is configured to be tapered. When the lower end of the flange tube 51 is inserted into the first tube body 1, the frictional resistance during the penetration is reduced, thereby ensuring a smooth and tight connection.

[0046] In this embodiment, the design of the flange tube 51 takes into account ease of installation and maintenance. The shorter first tube 1 makes the flange 5 connection more compact, facilitating positioning and adjustment during installation. The longer second tube 2 allows for easier removal and reinstallation for inspection or maintenance without exposing or damaging the internal first tube 1. This design simplifies on-site construction and improves maintenance convenience.

[0047] As a further preferred feature, in this embodiment, when the second tube body 2 is connected to the cylinder body 5112, a winding wire group II 8 is provided in the interval between the baffle 5111 and the cylinder body 5112 in the second tube body 2. Figure 1 As shown, the reinforcement layer III 22 of the second tube 2 is preferably composed of multiple layers of fabric, with adjacent fabrics bonded with adhesive to enhance overall strength. Multiple sets of winding wires II 8 are provided within the reinforcement layer III 22 to constrain the second tube 2 to the sleeve 511, achieving a secure connection and high stability.

[0048] At the same time, in order to further improve the connection between the two, refer to Figure 1 and Figure 2 As shown in FIG, ribs 513 are provided on the sleeve body 5112 in a direction perpendicular to its axis and are press-fitted with the second tube body 2. The ribs 513 are arranged around the outer circumference of the sleeve body 5112. When the flange sleeve 51 is inserted into the second tube body 2, the contact between the ribs 513 and the second tube body 2 can effectively improve the connection strength between the sleeve 511 and the second tube body 2, ensuring the stability and reliability of the connection.

[0049] Similarly, in this embodiment, as a preference, multiple rib rings 512 are spaced apart along the extension direction of the flange tube 51. At least the rib ring 512 near the lower end of the flange tube 51 has a wedge-shaped surface that slopes toward the upper end of the flange tube 51. In this embodiment, this design effectively disperses stress at the connection point, reducing localized stress concentration, thereby extending the service life of the flange 5 and its connection. This design also helps improve the stability of the flange 5 when subjected to external impact, ensuring the long-term reliability of the connection.

[0050] In this embodiment, there are two rib rings 512, which are arranged below the sleeve 511 and at a certain interval. In addition, the multiple rib rings 512 arranged at intervals on the flange tube 51 also effectively disperse stress and improve the stability of the connection part.

[0051] As an example, a winding steel wire group I 7 is provided in the first tube body 1 at the intervals between each two adjacent tendon rings 512. Figure 1 As shown in the figure, in the reinforcement layer I 12 of the second tube body 2, a winding steel wire group I 7 is provided between each two adjacent rib rings 512. This increases the mechanical strength of the first tube body 1, enabling it to better withstand changes in internal and external pressure. The reinforcement layers I 12 and II 14 in the first tube body 1 utilize the same materials and structural design as the aforementioned reinforcement layer III 22 in the second tube body 2.

[0052] In addition, in this embodiment, as a preference, a leak detector 6 for detecting crude oil leakage is provided on the flange 5. The leak detector 6 is arranged at the lower end of the sleeve 511 to be connected to the buffer layer 4. When the crude oil in the first tube body 1 leaks into the buffer layer 4, the leak detector 6 can monitor it in time and send an alarm message to the outside through the central processing unit.

[0053] Specific reference Figure 1 、 Figure 2 and Figure 4 As shown in the figure, the leak detector 6 on the flange 5 enters the metal skeleton layer 13 in the first tube body 1 through the conductive wire and finally passes through the other end to be connected to another flange 5. The conductivity of the steel wire in the metal skeleton layer 13 is used to complete the circuit arrangement.

[0054] In this embodiment, a leak detector 6 is integrated into the flange 5 and located within the buffer layer 4. This allows real-time monitoring of leaks within the first tube body 1. The leak detector 6 is connected to the other end of the flange 5 via conductive wires within the metal skeleton layer 13, utilizing the electrical conductivity of the wires to transmit signals. Once a leak is detected, the system immediately issues an alarm, providing early warning and preventing the spread of the leak. This built-in leak detection system not only improves safety but also simplifies maintenance, ensuring the reliability of the hose during operation.

[0055] Compared to the prior art, this embodiment of a floating hose with monitoring and early warning functions demonstrates that, when a crude oil leak occurs, the stepped space formed by the baffle 5111 and the main body 5112 on the flange 51 connects to the second tube 2. The stepped space between the main body 5112 and the flange 51 connects to the end of the first tube 1. The lower end of the flange 51 extends into the first tube 1 and connects to it. This enhances the sealing and mechanical strength of the connection between the flange 5 and the tube, ensuring the reliability of the connection. A leak detector 6 is also provided to provide a timely alarm when a leak occurs in the tube, thereby reducing the risk of crude oil leaks.

[0056] During use of the floating hose of this embodiment, the leak detector 6 can refer to monitoring structures such as pressure sensors or liquid level sensors in the prior art. When crude oil leaks, the pressurized crude oil in the buffer layer 4 is monitored by the leak detector 6. The leak detector 6 transmits a signal to the external control system and issues an alarm. The terminal connected to the external control system also displays the number of the leaking pipeline to the staff, allowing the leaking hose to be accurately located in the batch of hoses, thereby reducing losses.

[0057] The above description is only a preferred embodiment of this embodiment and is not intended to limit this embodiment. Any modifications, equivalent replacements and improvements made within the spirit and principles of this embodiment should be included in the scope of protection of this embodiment.
