[0002] The cable systems on large and medium-sized ships usually include power cables, communication cables, control cables, etc. These cables need to be safely supported and arranged to ensure the normal operation of the ship.

[0003] The cable tray on a ship is a device used to support and protect cables. It can effectively support the cables to prevent them from moving and swinging inside the ship, thereby ensuring the stability and reliability of the cable system; it can effectively protect the cables to prevent them from being physically damaged and chemically corroded by the outside world, thereby extending the service life of the cables; it can effectively arrange the cables to avoid cable crossing and confusion, thereby making the cable system tidier and easier to maintain; it is easy to maintain and overhaul, thereby reducing the cost and time of ship maintenance and ensuring the normal operation of the ship.

[0004] Existing ship cable bridges mostly use land-based cable bridges, which cannot cope well with the violent shaking of ships moving forward in waves.

[0031] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0032] Implementation example:

[0033] like Figure 1 As shown, a corrosion-resistant cable tray for large and medium-sized ships includes a fixed structure 2000 connected and fixed to the top of the cabin, and a bridge structure 1000 laid along the fixed structure 2000 for accommodating cables 3000.

[0034] like Figure 4-5 As shown, the bridge structure 1000 includes a frame 1100 and a cover 1200, and a clamping structure 1300 for clamping the cable 3000 in the frame 1100. The upper end surfaces of the support walls 1110 on both sides of the frame 1100 are provided with concave slots 1111, the connecting walls 1210 on both sides of the cover 1200 are matched with the corresponding sizes of the slots 1111, and the lower end surface of the cover 1200 is provided with a cover protrusion 1220 corresponding to the frame groove 1130 on the upper end surface of the support wall 1110. The connecting wall 1210 is inserted into the slot 1111, and the cover protrusion 1220 enters the frame groove 1130, completing the installation of the cover 1200 on the frame 1100, and at the same time realizing the closure of the bridge structure 1000, protecting the cable from corrosion, and spraying PTFE anti-corrosion coating on the outer surface of the bridge structure 1000 and the fixed structure 2000 to realize the anti-corrosion protection of the cable bridge itself.

[0035] The clamping structure 1300 includes a plurality of clamping blocks 1310 arranged in parallel, the upper end surface of the clamping block 1310 is provided with an upper clamping groove 1312, and the lower end surface is provided with a lower clamping groove 1311. The clamping block 1310 is movably connected to the frame slide rail 1120 on the inner lower surface of the frame 1100 through the lower clamping groove 1311, and the upper clamping groove 1312 is movably connected to the cover body protrusion 1220. The clamping block 1310 moves within the range of the frame slide rail 1120 and the cover body protrusion 1220 to clamp the cable.

[0036] Two elastic clamping blocks 1320 arranged on both sides of the clamping structure 1300 have clamping rods 1321 extending to both sides, passing through the supporting wall 1110 to the outside of the frame 1100. The elastic component 4000 arranged along the clamping rod 2313 abuts against the inner side of the supporting wall 1110 and the elastic clamping block 1320. In this embodiment, the elastic component 4000 is a spring. When placing the cable 3000, the clamping rods 1321 are pulled outward at both ends of the frame 1100, and the cable 3000 is placed between the clamping blocks 1310. The clamping rods 1321 are loosened, and the clamping blocks 1310 clamp the cable 3000 under the action of the spring, thereby achieving the clamping of the cable 3000 in the frame 1100, and at the same time having a buffering and shock absorbing effect.

[0037] like Figure 2 As shown, the fixed structure 2000 is arranged along the direction of laying the cable 3000, and includes a mounting plate 2100 fixed on the cabin, a mounting frame 2200 accommodating the supporting bridge structure 1000, and a buffer connection structure 2300 connecting the mounting plate 2100 and the mounting frame 2200. The mounting plate 2100 is provided with screw holes and is fixed to the cabin by bolts. The frame 1100 is laid on the mounting frame 2200, and the inner diameter of the mounting frame 2200 matches the outer diameter of the frame 1100.

[0038] like Figure 3 As shown, the buffer connection structure 2300 is symmetrically arranged on both sides of the bridge structure 1000, including a vertical connection rod 2310 and a horizontal connection rod 2320. The vertical connection rod 2310 includes a vertical connection upper sleeve rod 2311, a vertical connection lower sleeve rod 2312, and a vertical pull rod 2313 whose two ends are respectively inserted and connected in the vertical connection upper sleeve rod 2311 and the vertical connection lower sleeve rod 2312. The vertical connection upper sleeve rod 2311 is fixed to the lower end surface of the mounting plate 2100 by bolts, one end of the vertical pull rod 2313 is connected to the vertical connection upper sleeve rod 2311 by a spring, and the other end is connected to the vertical connection lower sleeve rod 2312 by a spring. The vertical pull rod 2313 moves in the vertical connection upper sleeve rod 2311 and the vertical connection lower sleeve rod 2312 to realize the buffering and shock absorption of the bridge structure 1000 in the vertical direction.

[0039] The horizontal connecting rod 2320 includes a first horizontal connecting rod 2321 and a second horizontal connecting rod 2322. The first horizontal connecting rod 2321 is connected to the top of the horizontal slot 2210 through a spring in the horizontal slot 2210 on the outside of the mounting frame 2200. The first horizontal connecting rod 2321 moves in the horizontal slot 2210 due to the tension of the spring to achieve shock absorption and buffering of the bridge structure 1000; the second horizontal connecting rod 2322 is provided with a concave slide groove 2323 on the end face facing the mounting frame 2200, and the slide groove 2323 is inserted into the horizontal protrusion 2220 of the mounting frame 2200. The end of the slide groove 2323 is connected to the top of the horizontal protrusion 2220 through a spring. The horizontal protrusion 2220 moves in the slide groove 2323 due to the tension of the spring to achieve shock absorption and buffering of the bridge structure 1000.

[0040] The vertical connecting rod 2310 and the horizontal connecting rod 2320 realize the shock absorption and buffering of the cable 3000 in the vertical and horizontal directions, and cooperate with the buffering effect of the clamping structure 1300 to better protect the cable 3000 when the ship is sailing at sea.
