Description

Technical Field

[0001] This utility model specifically relates to a highly adaptable ship cable sleeve and ship cable. Background Technology

[0002] Cable conduits, also known as protective conduits or ducts, are pipes used in electrical installations to protect wires and cables, allowing them to be inserted and replaced. They are a new type of conduit material widely used in power engineering. Currently, marine cables are used for power, lighting, and general control on various river and sea vessels and offshore oil platforms and other floating structures. They ensure the normal operation of various electrical equipment and serve as an important link connecting various electrical devices on a ship. During installation, they sometimes pass through decks or bulkheads. To protect the marine cables, a hatch is usually opened in the deck or bulkhead to insert the marine cable conduit, and then the marine cable is inserted through the inside of the marine cable conduit, thus ensuring the smooth laying of the marine cable.

[0003] However, when using current ship cable conduits, because ship cables vary in thickness and outer diameter, while the inner diameter of the ship cable conduit is a fixed value, the ship cables are always in a loose state inside, and are frequently subjected to collisions and friction. The outer sheath is easily worn or even cracked, which seriously affects the service life of the ship cables.

[0004] Therefore, it is necessary to invent a more adaptable ship cable conduit to solve the above problems. Utility Model Content

[0005] (a) Purpose of the utility model

[0006] To address the technical problems existing in the background art, this utility model proposes a highly adaptable marine cable conduit and marine cable. By incorporating clamping blocks, pressure blocks, sliders, and springs, the clamping blocks can hold the marine cable after it is inserted into the conduit, keeping it suspended inside the conduit. This provides excellent protection for the outer sheath, making the marine cable less prone to wear and breakage, and significantly extending its service life. Furthermore, because each set of clamping blocks is forced apart by the volume of the marine cable itself, and then tends to move closer together under the action of spring force, marine cables of different outer diameters can be firmly clamped by the clamping blocks, exhibiting high flexibility and being simple and convenient to use.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a highly adaptable marine cable conduit, installed on a ship, comprising a conduit body for installing marine cables;

[0009] Several sets of clamping blocks are evenly spaced inside the tube along the tube axis. Each set of clamping blocks has no less than two blocks, and the clamping blocks in each set can move closer or further apart from each other to clamp or release the ship cable that passes through the tube.

[0010] Several positioning components are respectively set on one side of each group of clamping blocks to position the clamping blocks.

[0011] Preferably, the clamping blocks in each group are evenly distributed in a circular array around the central column of the tube.

[0012] Preferably, the inner wall of the tube is connected to a limiting block at the clamping block, and the end of the limiting block away from the tube extends into the inside of the clamping block. The clamping block has a limiting groove inside that allows the limiting block to be inserted.

[0013] Preferably, the limiting block is T-shaped, and the limiting groove is adapted to the limiting block.

[0014] Preferably, each clamping block has a first inclined section on both the left and right sides, and each clamping block has an arc-shaped surface on both the top and bottom sides.

[0015] Preferably, each positioning component includes a pressure block that contacts the right side of the clamping block, a slider disposed between the pressure block and the inner wall of the tube and connected to the top of the pressure block, an annular plate connected to the inner wall of the tube, and a spring installed between the slider and the annular plate.

[0016] Preferably, each of the pressing blocks and clamping blocks is provided with a second inclined section on the side adjacent to it, and the second inclined section is adapted to the first inclined section.

[0017] Preferably, the tube body has a groove at the end of each slider for slider translation, and each spring has an inner liner plate inside, the inner liner plate being annular and connected to the side of the adjacent annular plate.

[0018] Preferably, a plurality of heat-conducting plates are installed inside the tube.

[0019] A marine cable, wherein the exterior of the marine cable is fitted with a highly adaptable marine cable sheath of this invention.

[0020] Compared with the prior art, the beneficial effects of the above-mentioned technical solution of this utility model are:

[0021] 1. This utility model, by setting up a clamping block, a pressure block, a slider and a spring, when the ship cable is inserted into the pipe, the first inclined section and the second inclined section will decompose the horizontal elastic force applied by the spring to the pressure block into a pressure parallel to the height direction of the clamping block and towards the ship cable at the clamping block, thereby achieving clamping of the ship cable. After the ship cable is laid, it is in a suspended state inside the pipe, which is not easy to collide or rub, and has a good means of protecting the outer sheath, making the ship cable less prone to wear and breakage, and greatly improving its service life;

[0022] 2. This utility model uses clamping blocks to hold the ship cables that pass through the tube body. The volume of the ship cables themselves forces the clamping blocks in each group to move away from each other. Under the action of spring force, they tend to move closer to each other. This allows ship cables of different outer diameters to be firmly clamped by the clamping blocks, which has high flexibility and is simple and convenient to use. Attached Figure Description

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0034] This utility model provides, for example Figure 1-6 The diagram shows a highly adaptable marine cable conduit, which is installed on a ship and includes a conduit body 1 for installing marine cables.

[0035] Several sets of clamping blocks 2 are evenly spaced along the axial direction of the tube body 1 inside the tube body 1. Each set of clamping blocks 2 has no less than two, and the clamping blocks 2 in each set can move closer or further away from each other, for clamping or releasing the ship cable that passes through the tube body 1.

[0036] Several positioning components 3 are respectively disposed on one side of each group of clamping blocks 2 for positioning the clamping blocks 2. Each positioning component 3 includes a pressure block 31 that contacts the right side of the clamping block 2, a slider 32 disposed between the pressure block 31 and the inner wall of the tube body 1 and connected to the top of the pressure block 31, an annular plate 33 connected to the inner wall of the tube body 1, and a spring 34 installed between the slider 32 and the annular plate 33.

[0037] In one embodiment, the clamping blocks 2 in each group are evenly distributed in a circular array around the central column of the tube body 1, so that the outer side of the ship cable passing through the tube body 1 can be clamped in multiple places to ensure its stability after being clamped.

[0038] In one embodiment, the inner wall of the tube body 1 is connected to the clamping block 2 at each clamping block 2. The end of the clamping block 4 away from the tube body 1 extends into the interior of the clamping block 2. The clamping block 2 has a limiting groove 5 inside which the clamping block 4 can be inserted. The clamping block 4 is T-shaped. The limiting groove 5 is adapted to the clamping block 4 so that when the clamping block 2 is spread apart by the ship cable, that is, when they are far apart, the tube body 1 will not move in the axial direction. That is, the clamping block 2 can only move along the length direction of its internal limiting block 4, thereby limiting the movement direction of the clamping block 2 and ensuring that the clamping block 2 can always be in close contact with the outside of the ship cable.

[0039] In one embodiment, each clamping block 2 is provided with a first inclined section 6 on both the left and right sides, and each pressure block 31 is provided with a second inclined section 35 on the side adjacent to the clamping block 2. The second inclined section 35 is adapted to the first inclined section 6. The first inclined section 6 on the left side facilitates the insertion of the ship cable and reduces the compression on the end of the ship cable when it is inserted. The first inclined section 6 on the right side can be adapted to the second inclined section 35, forcing the spring 34 to contract under force. The upper and lower surfaces of each clamping block 2 are set as arc surfaces, which can better adapt to the outer side of the ship cable and avoid the clamping block 2 applying relatively concentrated pressure to the outer side of the ship cable. Thus, when the ship cable is clamped, it not only has better protection, but also will not be damaged due to excessive clamping force.

[0040] In one embodiment, the tube body 1 has a groove 7 at the end of each slider 32 for translating the slider 32. Each spring 34 has an inner liner plate 8 inside. The inner liner plate 8 is annular and connected to the side of the adjacent ring plate 33. The groove 7 can ensure that the slider 32 moves horizontally after being pushed by the pressure plate, while the inner liner plate 8 can provide support and protection for the spring 34, so that the spring 34 will not be damaged due to compression during use.

[0041] In one embodiment, a plurality of heat-conducting plates 9 are installed inside the tube body 1, which can quickly dissipate the heat inside the tube body 1, thereby ensuring a good operating environment for the marine cable and further improving its service life.

[0042] An embodiment of a marine cable uses the highly adaptable marine cable sleeve of this invention on the outside of the marine cable, which makes the marine cable less prone to wear and breakage inside the sleeve after laying, and greatly improves its service life.

[0043] The specific implementation method is as follows: When the present invention is not in use, the slider 32 always tends to move towards the clamping block 2 under the action of the spring force of the spring 34. That is, the spring force of the spring 34 forces the pressure block 31 to contact the clamping block 2. At this time, multiple clamping blocks 2 in the same group approach each other.

[0044] The highly adaptable marine cable conduit is installed in a hatch on the ship's deck or bulkhead. The marine cable to be laid is then passed through the left side of conduit 1 and exits through the right side. Clamping blocks 2 automatically clamp the marine cable inside conduit 1, ensuring the cable is firmly held and suspended within the conduit. Specifically:

[0045] The ship cable passes through the gap formed by the arc surface between each group of multiple clamping blocks 2. At this time, the clamping blocks 2 will be subjected to a thrust from the volume of the ship cable itself, forcing the clamping blocks 2 to move away from each other synchronously. Due to the restriction of the limiting block 4, the clamping blocks 2 will not be displaced in the axial direction of the tube body 1. That is, the clamping blocks 2 will move away from each other in the length direction of the internal limiting block 4. At this time, the first inclined section 6 makes the second inclined section 35 tend to move in the length direction of the slider 32. Due to the restriction of the slide groove 7, the pressure plate will push the slider 32 to move in the length direction of the spring 34. At this time, the spring 34 will contract and shorten, storing elastic force.

[0046] Once the ship cable is fully inserted, the spring 34 of each positioning component 3 will apply a spring force to the slider 32. After being transmitted through the pressure plate, under the cooperation of the second inclined section 35 and the first inclined section 6, a pressure parallel to the height direction of the clamping block 2 and directed towards the ship cable is generated, thereby enabling the clamping block 2 to clamp the ship cable. The ship cable is in an airborne state, making it less prone to collision and friction. The outer sheath is also well protected, making it less prone to wear and breakage, and greatly improving its service life.

[0047] Furthermore, since the clamping blocks 2 are forced apart by the volume of the ship cable itself, and tend to move closer together due to the elastic force of the spring 34, ship cables of different outer diameters can be firmly clamped by the clamping blocks 2. This highly adaptable ship cable sleeve has high flexibility and is simple and convenient to use.

[0048] This embodiment specifically addresses the problem that in the current technology of ship cable conduits, due to the varying thickness and outer diameter of ship cables while the inner diameter of the conduit is a fixed value, the ship cables are constantly in a loose state inside, frequently colliding and rubbing against each other, causing the outer sheath to wear down or even crack, which seriously affects the service life of the ship cables.

[0049] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
