Technical Field
[0001] This utility model relates to the field of medium-voltage branch cable technology for ships, and in particular to an insulating protective layer for the branch section of a medium-voltage branch cable for ships. Background Technology
[0002] Cables are widely used as a means of transmitting electricity, especially in ships. Due to their use on ships, the insulation requirements for cable branch points are high, and insulation protection is required for cable branch points.
[0003] However, traditional insulation protection is usually quite simple and can only protect a certain section of the cable. It is not convenient to adjust the position after installation, and it is prone to shaking on ships. Traditional insulation protection can only be fixed in one place, and the line is easily damaged when shaking occurs. Utility Model Content
[0004] The main objective of this invention is to provide an insulating protective layer for the branch section of a medium-voltage branch cable used in ships, which can effectively solve the technical problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] An insulating protective layer for the branch section of a medium-voltage branch cable for ships includes a protective shell, and both ends of the protective shell are provided with adjustment structures.
[0007] The adjustment structure includes a fixed ring, which is fixedly connected to the protective shell. Four storage boxes are fixedly installed on one side of the fixed ring. An adjustment ring is rotatably installed on the outside of the fixed ring. An adjustment plate is slidably installed through the inside of the storage box. A guide rod is fixedly installed on the outside of the adjustment plate. The adjustment ring is connected to two screws by threads.
[0008] As a further embodiment of this utility model, an insulating layer and several sealing rings are fixedly provided on the inner side of the protective shell, and the guide rod and the storage box are slidably arranged through it.
[0009] As a further embodiment of this utility model, a plurality of threaded holes are provided on one side of the fixing ring, and the threads of the screw and the threads of the fixing ring are compatiblely matched.
[0010] As a further embodiment of this utility model, the outer surface of the adjusting ring is provided with four arc-shaped holes, and the arc-shaped holes of the guide rod and the adjusting ring are adaptively matched.
[0011] As a further embodiment of this utility model, the protective shell is provided with a limiting structure on its exterior. The limiting structure includes an outer sleeve and two limiting rings. The outer sleeve and the protective shell are rotatably connected, and the limiting rings and the protective shell are fixedly connected. The outer sleeve is fixedly provided with two hanging ears and two fixing plates. The fixing plates are connected to threaded rods by threads. One end of the threaded rod is rotatably connected to a limiting block, and one side of the limiting block is fixedly connected to a sliding rod.
[0012] As a further embodiment of this utility model, the limiting block and the limiting ring are adaptively matched, and the fixing plate is penetrated by the sliding rod.
[0013] The beneficial effects of this utility model are as follows:
[0014] The cable can be fixed inside the protective shell by setting an adjustment structure. When it is necessary to adjust the position of the cable under insulation protection, the screw can be removed and the adjustment ring can be turned. Conversely, when it is necessary to fix it, the adjustment ring can be adjusted and then the screw can be tightened.
[0015] By setting a limiting structure, the cable can be allowed to sway slightly when the ship rolls, reducing damage to the cable. Alternatively, the protective shell can be fixed in position to prevent the cable from swaying, which helps improve operational adaptability. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] like Figure 1-4 As shown, an insulating protective layer for the branch section of a medium-voltage branch cable for ships includes a protective shell 1, and an adjustment structure 2 is provided at both ends of the protective shell 1.
[0023] The adjustment structure 2 includes a fixed ring 6, which is fixedly connected to the protective shell 1. Four storage boxes 7 are fixedly installed on one side of the fixed ring 6. An adjustment ring 8 is rotatably installed on the outside of the fixed ring 6. An adjustment plate 9 is slidably installed through the inside of the storage box 7. A guide rod 10 is fixedly installed on the outside of the adjustment plate 9. The adjustment ring 8 is connected to two screws 11 by a thread.
[0024] The adjustment structure 2 allows the cable to be fixed inside the protective shell 1. When it is necessary to adjust the position of the cable under insulation protection, the screw 11 can be removed and the adjustment ring 8 can be rotated. Conversely, when it is necessary to fix it, the adjustment ring 8 can be used to adjust it and then the screw 11 can be fixed.
[0025] In this embodiment, an insulating layer 4 and several sealing rings 5 are fixedly provided on the inner side of the protective shell 1, and the guide rod 10 and the storage box 7 are slidably disposed through it.
[0026] Insulation layer 4 and sealing ring 5 serve to seal the cable.
[0027] In this embodiment, a plurality of threaded holes are provided on one side of the fixing ring 6, and the threads of the screw 11 and the threads of the threaded holes of the fixing ring 6 are compatiblely matched.
[0028] Screw 11 serves to limit the position of adjusting ring 8.
[0029] In this embodiment, the outer surface of the adjusting ring 8 is provided with four arc-shaped holes, and the guide rod 10 and the arc-shaped holes of the adjusting ring 8 are adaptively matched.
[0030] Under the action of the adjusting ring 8, the guide rod 10 slides along the inside of the storage box 7 with the adjusting plate 9.
[0031] In this embodiment, a limiting structure 3 is provided on the outside of the protective shell 1. The limiting structure 3 includes an outer sleeve 12 and two limiting rings 13. The outer sleeve 12 and the protective shell 1 are rotatably connected, and the limiting rings 13 and the protective shell 1 are fixedly connected. Two hanging ears 14 and two fixing plates 15 are fixedly provided on the outside of the outer sleeve 12. The fixing plates 15 are connected to threaded rods 16 by threads. One end of the threaded rod 16 is rotatably connected to a limiting block 17, and a sliding rod 18 is fixedly connected to one side of the limiting block 17.
[0032] The limiting structure 3 can allow the cable to sway slightly when the ship rolls, reducing damage to the cable. It can also fix the protective shell 1 in place as needed to prevent the cable from swaying, which helps to improve the adaptability of the work.
[0033] In this embodiment, the limiting block 17 and the limiting ring 13 are adaptively matched, and the fixing plate 15 is penetrated by the slide rod 18.
[0034] The slide bar 18 provides a constraint effect on the limit block 17.
[0035] It should be noted that this utility model is an insulation protection layer for the branch part of a medium-voltage branch cable for ships. When in use, it can be placed in the place where it needs to work to make it meet the working conditions.
[0036] Pass the cable through the inside of the protective shell 1. When the cable passes through to the area that requires insulation protection, remove the screw 11, rotate the adjusting ring 8 so that it acts on the guide rod 10 to move the adjusting plate 9 toward the outside of the cable until the adjusting plate 9 and the surface of the cable come into contact and stop. Then install the screw 11 into the corresponding position of the adjusting ring 8 and the fixing ring 6 to complete the limit fixation. At the same time, the insulation layer 4 and the sealing ring 5 are in close contact with the outside of the cable due to the elastic effect.
[0037] The outer sleeve 12 can be installed in the required position by using the expansion screw and the lug 14. When the ship rolls, the cable and the protective shell 1 will swing inside the outer sleeve 12 because the outer sleeve 12 and the protective shell 1 are rotatably connected. This will not damage the cable. When the cable does not need to swing freely, the threaded rod 16 can be rotated to insert the limit block 17 into the limit ring 13.
[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
