Description

Technical Field

[0001] This utility model relates to the field of submarine optical cable watertightness testing technology, and more specifically, to a tray for submarine optical cable watertightness testing. Background Technology

[0002] The development of marine communications and energy transmission has driven the demand for high-performance submarine optical cables. As a key infrastructure connecting different landmasses and islands for communication and power transmission, the reliability of submarine optical cables in extreme deep-sea environments is crucial.

[0003] During the manufacturing process of submarine optical cables, submarine optical cable companies need to connect and package all components, including the electronic compartment, the compartment connection node, and the submarine optical cable. After that, the connected assembly is placed in a watertight tank for a watertight test to simulate the watertight performance of the submarine optical cable under actual deployment conditions.

[0004] In the production and transportation stages of submarine optical cables, pallets are typically used to carry and protect the cables. Traditional submarine optical cable pallet designs often prioritize ease of ground logistics, employing a flat structure. This means the pallet's height is relatively small, but its length, width, or radial dimensions are relatively large. However, watertight tanks are usually vertically placed cylindrical pressure vessels, and traditional flat submarine optical cable pallets are difficult to fit into the vertical structure of these tanks. If the pallet, along with the wound submarine optical cable, is to be placed into the watertight tank simultaneously, a larger diameter watertight tank must be selected, increasing testing costs. Utility Model Content

[0005] The main purpose of this utility model is to provide a tray for watertight testing of submarine optical cables, so that the tray and the wound submarine optical cables can be placed into a small watertight container for watertight testing, thereby reducing testing costs.

[0006] To achieve the above objectives, this utility model provides a tray for testing the water tightness of submarine optical cables, comprising: a support base; a limiting component, including an inner limiting component and an outer limiting component, the outer limiting component being circumferentially disposed along the outer contour of the support base at the outer periphery of the support base, the inner limiting component being disposed on the support base and located inside the outer limiting component, the inner limiting component and the outer limiting component being spaced apart to form an annular accommodating space for accommodating submarine optical cables; a supporting member, connected to the outer limiting component and located at one end of the support base along its length direction; the tray for testing the water tightness of submarine optical cables has a horizontal placement state supported by the support base and a vertical placement state supported by the supporting member, wherein the maximum length dimension of the tray for testing the water tightness of submarine optical cables is L1, the maximum width dimension of the tray for testing the water tightness of submarine optical cables is L2, and the maximum height dimension of the tray for testing the water tightness of submarine optical cables is H, wherein L1 > L2 and L1 > H.

[0007] Furthermore, when the tray for the watertightness test of the submarine optical cable is in a vertical position, the outer contour of the projection of the supporting component in the horizontal plane is located within the outer contour of the projection of the whole formed by the limiting component and the support base in the horizontal plane.

[0008] Furthermore, the support member includes: a bottom support portion; two side support portions, each side support portion being disposed on the side of the bottom support portion facing the outer limiting component, the bottom support portion and the two side support portions defining a limiting space, and one end of the outer limiting component facing the support member being disposed within the limiting space; and fasteners, the support member and the outer limiting component being detachably connected by fasteners.

[0009] Furthermore, one end of the outer limiting component facing the support member is an arc-shaped structure protruding towards the support member. Two side support parts are distributed at intervals along the extension direction of the arc-shaped structure. Each side support part includes a connecting rod and two support members. The two support members are distributed in a direction perpendicular to the support base. The two ends of the connecting rod are respectively connected to the two corresponding support members. Each support member includes a support rod. The support rod has an included angle with the bottom support part. The support rod is used to support the outer limiting component.

[0010] Furthermore, the outer contour of the support base includes two arc-shaped segments arranged opposite each other along the length direction of the support base and two straight segments arranged opposite each other along the width direction of the support base. The two straight segments are parallel to each other, and the two arc-shaped segments are located at the two ends of the two straight segments respectively. The ends of the arc-shaped segments and the straight segments that are close to each other are connected to each other. The distance between the two straight segments is L2, and the maximum distance between the two arc-shaped segments is greater than the distance between the two straight segments. Alternatively, the support base includes an annular plate and multiple connecting rods located inside the annular plate. The two ends of each connecting rod are connected to the inner periphery of the annular plate respectively. The outer limiting component is annularly arranged at the outer periphery of the annular plate, and the inner limiting component is annularly arranged at the inner periphery of the annular plate. The side of the annular plate facing the outer limiting component is a plane.

[0011] Furthermore, the tray for the watertightness test of the submarine optical cable also includes: a structural reinforcement member disposed between one end of the inner limiting component away from the support member and one end of the outer limiting component away from the support member, the two ends of the structural reinforcement member being detachably connected to one end of the inner limiting component away from the support member and one end of the outer limiting component away from the support member, respectively; and / or, a horizontal lifting lug member disposed at one end of the outer limiting component away from the support member, the horizontal lifting lug member having a first through hole; a vertical lifting lug member disposed at one end of the outer limiting component away from the support member, the vertical lifting lug member having a second through hole; and a fixing ring disposed on at least one of the limiting component and the support member, the fixing ring cooperating with the strap to fix the submarine optical cable.

[0012] Furthermore, the inner limiting component includes multiple inner limiting members, which are spaced apart along the annular direction; the arrangement density of the inner limiting members at the end away from the supporting member is greater than the arrangement density of the inner limiting members at other positions; and / or, a first reinforcing rib is provided at the connection position of the inner limiting member with the supporting base.

[0013] Furthermore, the outer limiting component includes: multiple outer limiting members, which are spaced apart along the outer periphery of the support base; and connecting members, at least one connecting member is provided between two adjacent outer limiting members, and the two ends of the connecting member are respectively connected to the two corresponding outer limiting members. The number of connecting members connected to the outer limiting member at the end closest to the support member is greater than the number of connecting members connected to the outer limiting members at other positions.

[0014] Furthermore, the inner limiting component is arranged in a ring on the support base, and the tray for the watertightness test of the submarine optical cable also includes at least one electronic compartment tooling, which is located inside the inner limiting component.

[0015] Furthermore, the electronic compartment tooling is in multiple parts, arranged sequentially along a direction perpendicular to the support base, with adjacent electronic compartment tooling detachably connected; or, the electronic compartment tooling includes a support plate and at least one clamp, the support plate having a support groove for supporting the electronic compartment, the clamp being detachably connected to the support plate, and the clamp and support plate forming an installation space for installing the electronic compartment.

[0016] Applying the technical solution of this utility model, the submarine optical cable is wound within the accommodating space of the submarine optical cable watertightness test tray. When transporting, hoisting, or storing the submarine optical cable watertightness test tray, it is placed horizontally. At this time, the maximum dimension (H) of the submarine optical cable watertightness test tray in the vertical direction is relatively small, while the dimensions in the radial direction (maximum width dimension L2, maximum length dimension L1) are relatively large. This setting can lower the center of gravity of the submarine optical cable watertightness test tray, facilitating stable handling and stacking storage of the submarine optical cable watertightness test tray. During the watertightness test, the submarine optical cable watertightness test tray can be changed to a vertical placement state. In this way, the submarine optical cable watertightness test tray can be placed into a watertight container with a smaller diameter. That is, it is only necessary to ensure that the diameter of the watertight container is greater than H and L2, rather than ensuring that the diameter of the watertight container is greater than L1. Furthermore, the support structure allows the tray for the watertightness test of submarine optical cables to stand stably in an upright position, improving stability and convenience during the watertightness test.

[0036] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0037] In existing technologies, submarine optical cables are typically wound on flat pallets to facilitate transportation and hoisting operations. Flat pallets have a larger radial dimension (for long, narrow pallets, this refers to both length and width dimensions; for cylindrical pallets, this refers to diameter dimensions) and a smaller height dimension.

[0038] However, when placing the aforementioned flat tray along with the submarine optical cable in a watertight container for a watertight test, this type of tray presents significant limitations. Because watertight containers (pressure vessels) are typically vertically placed cylindrical structures, a larger diameter watertight container is required to accommodate the tray with a larger radial dimension. This increases the cost of the testing equipment and may also increase energy consumption and operational complexity during the test due to the increased container volume. Therefore, the applicant provides the following tray for submarine optical cable watertight testing, described in detail below:

[0039] like Figures 1 to 9As shown, this embodiment of the utility model provides a tray for testing the water tightness of submarine optical cables. The tray for testing the water tightness of submarine optical cables includes a support base 10, a limiting component, and a supporting member 40. The limiting components include an inner limiting component 20 and an outer limiting component 30. The outer limiting component 30 is arranged in a ring around the outer periphery of the support base 10. The inner limiting component 20 is arranged on the support base 10 and located inside the outer limiting component 30. The inner limiting component 20 and the outer limiting component 30 are spaced apart to form a ring-shaped accommodating space for accommodating the submarine optical cable. The supporting member 40 is connected to the outer limiting component 30 and is located at one end of the length direction of the support base 10. The submarine optical cable watertightness test tray has a horizontal placement state supported by the support base 10 and a vertical placement state supported by the supporting member 40. The maximum length dimension of the submarine optical cable watertightness test tray is L1, the maximum width dimension of the submarine optical cable watertightness test tray is L2, and the maximum height dimension of the submarine optical cable watertightness test tray is H, where L1 > L2 and L1 > H.

[0040] like Figures 1 to 3 As shown, it can be understood that the maximum length of the tray for the watertightness test of the submarine optical cable is defined as L1, the maximum width of the tray for the watertightness test of the submarine optical cable is L2, and the maximum height of the tray for the watertightness test of the submarine optical cable is H. The above dimensions refer to the dimensions measured when the tray for the watertightness test of the submarine optical cable is placed horizontally; when the tray for the watertightness test of the submarine optical cable is placed vertically, the height of the tray for the watertightness test of the submarine optical cable is L1 in the vertical direction.

[0041] Applying the technical solution of this utility model, the submarine optical cable is wound within the accommodating space of the submarine optical cable watertightness test tray. When transporting, hoisting, or storing the submarine optical cable watertightness test tray, it is placed horizontally. At this time, the maximum dimension (H) of the submarine optical cable watertightness test tray in the vertical direction is relatively small, while the dimensions in the radial direction (maximum width dimension L2, maximum length dimension L1) are relatively large. This setting can lower the center of gravity of the submarine optical cable watertightness test tray, facilitating stable handling and stacking storage of the submarine optical cable watertightness test tray. During the watertightness test, the submarine optical cable watertightness test tray can be changed to a vertical placement state. In this way, the submarine optical cable watertightness test tray can be placed into a watertight container with a smaller diameter. That is, it is only necessary to ensure that the diameter of the watertight container is greater than H and L2, rather than ensuring that the diameter of the watertight container is greater than L1. Furthermore, the support component 40 enables the tray for the water tightness test of submarine optical cable to stand stably in an upright position, improving the stability and convenience during the water tightness test.

[0042] Specifically, when the submarine optical cable watertightness test tray is in an upright position, the outer contour of the projection of the support member 40 in the horizontal plane is located within the outer contour of the projection of the entire assembly formed by the limiting component and the support base 10 in the horizontal plane. With this configuration, when placing the submarine optical cable watertightness test tray in a watertight container, it is not necessary to consider whether the support member 40 meets the radial dimension requirements of the watertight container, allowing the submarine optical cable watertightness test tray to more easily match and adapt to the appropriate watertight container.

[0043] like Figure 3 and Figure 4 As shown in the embodiment of this solution, the support member 40 includes a bottom support portion 41, side support portions 42, and fasteners 43. There are two side support portions 42, each disposed on the side of the bottom support portion 41 facing the outer limiting component 30. The bottom support portion 41 and the two side support portions 42 define a limiting space, and one end of the outer limiting component 30 facing the support member 40 is disposed within this limiting space. The support member 40 and the outer limiting component 30 are detachably connected via fasteners 43. The bottom support portion 41 serves as the foundation of the support member 40, ensuring that the tray for the submarine optical cable watertight test can stand stably in the watertight tank during the watertight test. The bottom support portion 41 and the two side support portions 42 provide support points for different parts of the outer limiting component 30, thereby enhancing the load-bearing capacity of the support member 40.

[0044] In this embodiment, one end of the outer limiting component 30 facing the support member 40 is an arc-shaped structure protruding towards the support member 40, and the bottom support portion 41 contacts and supports the outermost end of the outer limiting component 30. This arrangement ensures that the tray for the watertightness test of the submarine optical cable maintains good balance when placed vertically.

[0045] Furthermore, the two side support portions 42 are symmetrically distributed on both sides of the outermost end of the outer limiting component 30 along the extension direction of the arc-shaped structure. This arrangement enhances the lateral stability of the tray for the submarine optical cable watertightness test. The side support portions 42 not only provide additional radial support for the outer limiting component 30, but also, through their symmetrical layout, balance the lateral forces (such as water pressure) that may act on the outer limiting component 30, improving the tray's ability to resist lateral external forces and enhancing its stability when placed vertically. Moreover, the above arrangement ensures the structural compactness of the support member 40 and the outer limiting component 30 after they are fitted together, minimizing the maximum length dimension L1 of the tray.

[0046] In this embodiment, the bottom support 41 is a rectangular frame structure, comprising two opposing first rods 411 and two opposing second rods 412, wherein the two first rods 411 are distributed along a direction perpendicular to the support base 10. The side support 42 comprises a connecting rod 421 and two support members 422, wherein the two support members 422 of each side support 42 are distributed along a direction perpendicular to the support base 10, and the two ends of the connecting rod 421 are respectively connected to the corresponding two support members 422. The two support members 422 of each side support 42 are respectively disposed on the two first rods 411, and the connecting rod 421 is parallel to the second rods 412.

[0047] In this embodiment, the support member 422 includes a support rod 4221 and an inclined rod 4222 connected to each other, with an included angle between them. One end of the support rod 4221 away from the inclined rod 4222 is mounted on a first rod body 411, and the other end of the inclined rod 4222 away from the support rod 4221 is also mounted on the first rod body 411. A triangular structure is formed between the first rod body 411, the support rod 4221, and the inclined rod 4222, located between the inclined rod 4222 and the support rod 4221. The support rod 4221 supports the outer limiting component 30. This configuration improves the support stability of the support member 422.

[0048] like Figure 1 and Figure 2 As shown, specifically, the outer contour of the support base 10 includes two arc-shaped segments 101 arranged opposite each other along the length direction of the support base 10 and two straight segments 102 arranged opposite each other along the width direction of the support base 10. The two straight segments 102 are parallel to each other, and the two arc-shaped segments 101 are located at the two ends of the two straight segments 102 respectively. The ends of the arc-shaped segments 101 and the straight segments 102 that are close to each other are connected to each other. The distance between the two straight segments 102 is L2, and the maximum distance between the two arc-shaped segments 101 is greater than the distance between the two straight segments 102. This arrangement allows the entire submarine optical cable watertightness test tray to form a long strip rather than a cylindrical structure, enabling the entire submarine optical cable watertightness test tray to be smoothly placed into the watertight tank when it is placed vertically.

[0049] In one embodiment of this solution, two arc segments 101 are symmetrically arranged at both ends of two straight segments 102.

[0050] like Figure 1 , Figure 5 and Figure 6As shown in the embodiment of this solution, the support base 10 includes an annular plate 11 and a plurality of connecting rods 12 located inside the annular plate. The two ends of each connecting rod 12 are connected to the inner periphery of the annular plate 11. An outer limiting component 30 is annularly disposed at the outer periphery of the annular plate 11, and an inner limiting component 20 is annularly disposed at the inner periphery of the annular plate 11. This arrangement allows the winding path of the submarine optical cable to bend along the shape of the annular plate 11, reducing additional stress on the submarine optical cable during the winding process and protecting the structural integrity and functionality of the submarine optical cable.

[0051] Furthermore, the side of the annular plate 11 facing the outer limiting component 30 is flat. This arrangement allows the flat surface to contact the submarine optical cable located at the bottom, reducing the possibility of indentations appearing on the surface of the submarine optical cable that is in direct contact with the support base 10.

[0052] In this embodiment, the multiple connecting rods 12 include multiple intersecting horizontal and vertical rods. This arrangement ensures the structural strength of the support base 10 while also achieving a lightweight design.

[0053] Furthermore, an annular recess is formed on the side of the support base 10 away from the limiting component, and a plurality of second reinforcing ribs 13 are provided in the annular recess. The plurality of second reinforcing ribs 13 are arranged at intervals along the circumference of the recess. The provision of the second reinforcing ribs 13 further improves the structural stability of the support base 10.

[0054] like Figure 1 As shown in the embodiment of this solution, the tray for the submarine optical cable watertightness test also includes a structural reinforcement 50. The structural reinforcement 50 is disposed between the end of the inner limiting component 20 away from the supporting member 40 and the end of the outer limiting component 30 away from the supporting member 40. The two ends of the structural reinforcement 50 are detachably connected to the ends of the inner limiting component 20 and the outer limiting component 30 away from the supporting member 10, respectively. When the tray for the submarine optical cable watertightness test is in a vertically placed state, the submarine optical cable exerts a large pressure on the end of the inner limiting component 20 away from the supporting member 40. The structural reinforcement 50 can reduce the deformation of the inner limiting component 20 due to excessive pressure.

[0055] Specifically, multiple structural reinforcement members 50 are provided, and the multiple structural reinforcement members 50 are provided at the arc-shaped structure of the inner limiting component 20 and the outer limiting component 30 at the end away from the supporting member 40, and the multiple structural reinforcement members 50 are distributed at intervals along the extension direction of the arc-shaped structure.

[0056] In this embodiment, the structural reinforcement 50 includes a plurality of tie bolts.

[0057] like Figure 1As shown, the submarine optical cable watertightness test tray further includes a horizontal lifting lug component 61, which is located at the end of the outer limiting component 30 away from the support base 10. The horizontal lifting lug component 61 has a first through hole. This configuration facilitates the lifting operation of the submarine optical cable watertightness test tray when it is in a horizontal placement state.

[0058] In this embodiment, four horizontal lifting lug components 61 are arranged circumferentially at intervals along the end of the outer limiting component 30 away from the support seat 10.

[0059] Furthermore, the tray for the submarine optical cable watertightness test also includes a vertical lifting lug component 62, which is located at the end of the outer limiting component 30 away from the supporting component 40, and has a second through hole. This configuration facilitates the lifting operation of the tray for the submarine optical cable watertightness test when it is in an upright position.

[0060] In this embodiment, two vertical lifting lugs 62 are provided at both ends of the arc-shaped structure of the outer limiting component 30 away from the support member 40, and the two vertical lifting lugs 62 located on the same side are distributed at intervals along a direction perpendicular to the support base 10.

[0061] Furthermore, the tray for the watertightness test of the submarine optical cable also includes a retaining ring 63, which is disposed on at least one of the limiting component and the support base 10. The retaining ring 63 cooperates with the strap to secure the submarine optical cable.

[0062] In this embodiment, multiple fixing rings 63 are provided. Multiple fixing rings 63 can be provided at the inner periphery of the annular plate 11, the outer periphery of the annular plate 11, on the connecting rod 12, on the outer limiting component 30, and on the inner limiting component 20.

[0063] Furthermore, the inner limiting assembly 20 includes multiple inner limiting elements 21, which are spaced apart along a circumferential direction. The density of the inner limiting elements 21 at the end furthest from the supporting member 40 is greater than that at other locations. When the tray for the submarine optical cable watertightness test is placed vertically, the weight of the submarine optical cable will be mainly concentrated on the multiple inner limiting elements 21 at the end furthest from the supporting member 40, resulting in a larger load on the inner limiting elements 21 in this area. In this solution, increasing the density of the inner limiting elements 21 at the end furthest from the supporting member 40 can better distribute the pressure applied by the submarine optical cable, reduce the pressure on a single inner limiting element 21, and reduce the possibility of deformation of a single inner limiting element 21 due to excessive pressure.

[0064] In this embodiment of the solution, multiple inner limiting members 21 are arranged at annular intervals on the inner periphery of the annular plate 11.

[0065] Furthermore, a first reinforcing rib is provided at the connection position between the inner limiting member 21 and the support base 10. The provision of the first reinforcing rib can further improve the stability of the connection between the inner limiting member 21 and the support base 10.

[0066] In this embodiment of the solution, the first reinforcing rib is located outside the accommodating space. This arrangement can prevent the submarine optical cable from coming into contact with the first reinforcing rib and prevent the surface of the submarine optical cable from being pressed into the first reinforcing rib with indentations.

[0067] Furthermore, the outer limiting assembly 30 includes an outer limiting member 31 and a connecting member 32. Multiple outer limiting members 31 are provided, spaced apart along the outer periphery of the support base 10; at least one connecting member 32 is provided between two adjacent outer limiting members 31. This arrangement improves the stability of the outer limiting assembly 30.

[0068] In this embodiment, the two ends of the connector 32 are respectively connected to two corresponding outer limiting members 31. The number of connectors 32 connected to the outer limiting member 31 at the end near the support member 40 is greater than the number of connectors 32 connected to the outer limiting member 31 at other locations. When the tray for the submarine optical cable watertightness test is placed vertically, the multiple outer limiting members 31 at the end near the support member 40 mainly bear the pressure from the submarine optical cable for the outer limiting component 30. In this embodiment, the increased number of connectors 32 connected to the outer limiting member 31 at the end near the support member 40 creates a denser network structure between the connectors 32 and the outer limiting members 31 in this area, reducing the possibility of deformation of the connectors 32 and the outer limiting members 31 in this area.

[0069] In this embodiment of the solution, in the inner limiting member 21 and the outer limiting member 31 at the end away from the supporting member 40, two tie rods are provided between each pair of opposing inner limiting members 21 and outer limiting members 31.

[0070] Combination Figures 7 to 9 As shown, the submarine optical cable watertightness test tray further includes at least one electronic compartment fixture 70, which is located inside the inner limiting component 20, specifically within the space enclosed by multiple inner limiting components 21. By directly integrating the electronic compartment fixture 70 and the submarine optical cable onto the same submarine optical cable watertightness test tray, the entire system can be directly placed into the watertight tank for testing after the electronic compartment and the submarine optical cable are connected, without the need for additional transfer or repositioning processes, saving time and labor costs.

[0071] Furthermore, by placing the electronic cabin tooling 70 inside the inner space of the inner limiting component 20, the internal volume of the submarine optical cable watertight test tray is fully utilized, avoiding additional space occupation. This allows the submarine optical cable watertight test tray to adapt to smaller watertight tanks, reducing test costs.

[0072] In this embodiment, there are multiple electronic cabin fixtures 70, which are arranged sequentially along a direction perpendicular to the support base 10, and adjacent electronic cabin fixtures 70 are detachably connected. The bottommost electronic cabin fixture 70 is detachably fixed to multiple connecting rods 12 by bolts. This arrangement improves the adaptability of the device; a specific number of electronic cabin fixtures 70 can be set according to actual working conditions, providing greater flexibility.

[0073] Specifically, the tray for the watertightness test of the submarine optical cable in this solution also includes vertical rods 80. Multiple vertical rods 80 are arranged between two adjacent electronic compartment fixtures 70, and these rods 80 are arranged in a ring around the periphery of the main body of the electronic compartment fixture 70. The two ends of each vertical rod 80 are detachably connected to the corresponding two electronic compartment fixtures 70 via bolts. This arrangement facilitates the assembly and disassembly of adjacent electronic compartment fixtures 70.

[0074] Specifically, the electronic compartment fixture 70 includes a support plate 71 and at least one clamp 72. The support plate 71 has a support groove 711 for supporting the electronic compartment. The clamp 72 is detachably connected to the support plate 71. The clamp 72 and the support plate 71 form an installation space for installing the electronic compartment. Multiple vertical rods 80 are located on the outer periphery of the support plate 71. This arrangement improves the stability and convenience of fixing the electronic compartment.

[0075] In this embodiment, both ends of the clamp 72 are detachably connected to the support plate 71 by bolts.

[0076] Furthermore, the support groove 711 includes a bottom wall and two oppositely arranged side walls, both of which are inclined, and the distance between the two side walls gradually increases in the direction away from the bottom wall.
