[0002] Ships have numerous cables, densely packed together. Ship branch cable protection covers are devices used to protect cable connections. They are typically installed at cable branch points or joints to prevent damage from external factors such as collisions and friction, thus ensuring the safe and stable operation of the electrical system. These protective covers effectively extend cable lifespan and reduce maintenance costs.

[0003] In the existing technology of ship branch cables, during the cabling process, the cable connecting the cargo hold branch cable conduit and the cargo hold main bracket is often exposed to direct sunlight. In addition, during the ship's operation, the branch cable and cable conduit may shake, resulting in mechanical damage such as friction between the cable connecting the cargo hold branch cable conduit and the cargo hold main bracket.

[0004] Therefore, a protective cover for ship branch cables is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, such as the problem of cables at the connection between the cargo hold branch cable conduit and the main cargo hold bracket being exposed to direct sunlight, and the mechanical damage caused by friction between the branch cables and cable conduits during ship movement due to shaking, a protective cover for ship branch cables is proposed.

[0007] Preferably, a slide rail is fixedly connected to the bottom end of the cover plate body, and a positioning sleeve is slidably connected to the outer wall of the slide rail, with the inner wall of the positioning sleeve inserted into the outer wall of the cable pipe.

[0008] Preferably, a mounting frame is fixedly connected to the top of the cover plate body, and steel wire ropes are fixedly connected to both sides of the positioning sleeve. A take-up drum is fixedly connected to the ends of the two steel wire ropes that are far apart from each other. The two take-up drums are located at positions far apart from each other inside the mounting frame, and the tops of the two take-up drums are rotatably connected to the inside of the mounting frame.

[0009] Preferably, a rotating block is fixedly connected to the bottom end of one of the take-up reels, a cylinder is slidably connected to the outer wall of the rotating block, a rectangular rod is slidably connected to the bottom end of the rotating block, the bottom end of the rectangular rod is fixedly connected to the bottom end of the inner part of the cylinder, an operating wheel is fixedly connected to the bottom end of the cylinder, a plurality of fixing holes penetrating the operating wheel are equally spaced at the bottom end of the operating wheel, and a positioning post is fixedly connected to the bottom end of the mounting frame, the size and shape of the outer wall of the positioning post being adapted to the size and shape of the inner wall of the fixing hole.

[0010] Preferably, a spring is fixedly connected to the bottom end inside the cylinder, and the top end of the spring is fixedly connected to the bottom end of the rotating block.

[0011] Preferably, a linkage assembly is fixedly installed at the top of the two take-up drums. The linkage assembly includes two toothed drive wheels and a toothed belt. The inner wall of the toothed belt is meshed with the outer wall of the two toothed drive wheels, and the bottom end of the two toothed drive wheels is fixedly connected to the top of the two take-up drums.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0013] 1. This utility model provides a protective cover for ship branch cables. The branch cable cover is fixed to one side of the main bracket cover by screws. The branch cable cover can protect the cable connecting the cargo hold branch cable pipe and the cargo hold main bracket, prevent it from being exposed to direct sunlight, and extend its service life. The rubber protective sleeve can prevent the end of the screw from directly contacting the outer wall of the cable assembly, thereby preventing wear of the cable assembly insulation.

[0014] 2. This utility model provides a protective cover for branch cables on ships. By sliding the positioning sleeve at the bottom of the slide rail, the position of the cable pipe can be adjusted according to the wiring of the branch cables, avoiding excessive bending of the branch cables in some cases, which would lead to problems such as wear of the insulation. By setting a spring, the operating wheel is always kept upward without external force, thereby ensuring the fixing effect between the fixing hole and the positioning stake. At the same time, when it is necessary to adjust the cable pipe, it is only necessary to pull down the operating wheel and rotate it, which improves the convenience of cable pipe adjustment.

[0022] 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.

[0023] Specific implementation examples are given below.

[0024] Please see Figure 1 - Figure 5This utility model provides a technical solution: a protective cover for ship branch cables, including a main support bracket cover 1, a branch cable cover 3, and a cable conduit 4. The main support bracket cover 1 contains several cable assemblies 2. The branch cable cover 3 is fixed to one side of the main support bracket cover 1 by bolts. The branch cable cover 3 includes a cover body 31 and a cover flange 32. Screw holes are provided on the top of the cover body and near the main support bracket cover 1 on the cover flange 32. Several rubber protective sleeves 5 are fixedly connected inside the main support bracket cover 1, with the positions of the rubber protective sleeves 5 corresponding to the positions of the screw holes. The branch cable cover 3 is fixed to one side of the main support bracket cover 1 by screws. The branch cable cover 3 can protect the cable connecting the cargo hold branch cable conduit 4 and the cargo hold main support bracket, preventing it from being exposed to direct sunlight and extending its service life. The rubber protective sleeves 5 can prevent the ends of the screws from directly contacting the outer wall of the cable assembly 2, thus avoiding wear and tear on the insulation of the cable assembly 2.

[0025] like Figure 3 As shown, a slide rail 33 is fixedly connected to the bottom of the cover plate body 31. A positioning sleeve 34 is slidably connected to the outer wall of the slide rail 33. The inner wall of the positioning sleeve 34 is inserted into the outer wall of the cable pipe 4. By sliding the positioning sleeve 34 at the bottom of the slide rail 33, the position of the cable pipe 4 can be adjusted according to the wiring of the branch cable, so as to avoid excessive bending of the branch cable in some cases, which would help with problems such as insulation wear.

[0026] like Figure 4 As shown, a mounting frame 35 is fixedly connected to the top of the cover body 31, and steel wire ropes 36 are fixedly connected to both sides of the positioning sleeve 34. A take-up drum 37 is fixedly connected to the ends of the two steel wire ropes 36 that are far apart from each other. The two take-up drums 37 are located inside the mounting frame 35 at positions far apart from each other, and the tops of the two take-up drums 37 are rotatably connected to the inside of the mounting frame 35. The rotation of the two take-up drums 37 can make the sliding adjustment of the positioning sleeve 34 more stable, avoiding the problem that the positioning sleeve 34 can slide excessively in one direction due to unidirectional adjustment.

[0027] like Figure 4 and Figure 5As shown, a rotating block 39 is fixedly connected to the bottom end of a take-up drum 37. A cylinder 38 is slidably connected to the outer wall of the rotating block 39. A rectangular rod is slidably connected to the bottom end of the rotating block 39. The bottom end of the rectangular rod is fixedly connected to the bottom end inside the cylinder 38. An operating wheel 311 is fixedly connected to the bottom end of the cylinder 38. Several fixing holes 312 are evenly spaced at the bottom end of the operating wheel 311. A positioning post 313 is fixedly connected to the bottom end of the mounting frame 35. The size and shape of the outer wall of the positioning post 313 are adapted to the size and shape of the inner wall of the fixing hole 312. Through the insertion action between the fixing hole 312 and the positioning post 313, the operating wheel 311 can be fixed, thereby improving the stability of the take-up drum 37 and thus improving the stability effect of the positioning sleeve 34.

[0028] like Figure 5 As shown, a spring 310 is fixedly connected to the bottom of the cylinder 38. The top of the spring 310 is fixedly connected to the bottom of the rotating block 39. By setting the spring 310, the operating wheel 311 is always kept upward without external force, thereby ensuring the fixing effect between the fixing hole 312 and the positioning post 313. At the same time, when it is necessary to adjust the cable pipe 4, it is only necessary to pull down the operating wheel 311 and rotate it, which improves the convenience of adjusting the cable pipe 4.

[0029] like Figure 5 As shown, a linkage assembly 314 is fixedly installed at the top of the two take-up drums 37. The linkage assembly 314 includes two toothed drive wheels and a toothed belt. The inner wall of the toothed belt meshes with the outer wall of the two toothed drive wheels. The bottom ends of the two toothed drive wheels are fixedly connected to the top of the two take-up drums 37. Through the action of the linkage assembly 314, the two take-up drums 37 can be made to rotate synchronously, so that one take-up drum 37 unwinds the wire rope 36 and the other take-up drum 37 winds the wire rope 36. This ensures that the positioning sleeve 34 has a fixing effect at any node during the adjustment process, thereby ensuring the stability of the positioning sleeve 34, the cable pipe 4, and the branch cable.

[0030] The working principle of this utility model is as follows: In use, the branch cable assembly 2 of the cargo hold is routed through the cable conduit 4 to the inside of the main support bracket cover 1. Then, the branch cable cover 3 is fixed to one side of the main support bracket cover 1 with screws. At this time, the branch cable cover 3 can protect the cable connecting the cargo hold branch cable conduit 4 and the cargo hold main support bracket, preventing it from being exposed to direct sunlight. At the same time, it can limit the cable of the connecting part, improve its stability, thereby reducing the risk of mechanical damage and extending its service life. Pulling down the operating wheel 311 causes the fixing hole 312 to engage with the positioning stake 31. 3. When disengaged, rotating the operating wheel 311 will drive the rotating block 39 to rotate, which in turn drives one take-up drum 37 to rotate. Through the action of the linkage component 314, the two take-up drums 37 can rotate synchronously, so that one take-up drum 37 unwinds the wire rope 36 and the other take-up drum 37 winds the wire rope 36. Under the action of the slide rail 33, the cable tube 4 can slide smoothly, and the position of the cable tube 4 can be adjusted for the branch cable wiring, avoiding excessive bending of the branch cable in some cases, which would help with insulation wear and other problems.

[0031] 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.
