[0037] like Figure 1As shown, in this embodiment, a ship cable fixing device is installed on a cable bracket, and the cable bracket includes two main beams that are opposite and spaced apart. The ship cable fixing device includes a support plate 1, a fixing plate 2 and a connecting piece. Among them, the support plate 1 is located between the two main beams, and the support plate 1 is provided with a fixing hole 11, and the fixing hole 11 is used to fix the cable. There are two fixing plates 2, and the two fixing plates 2 are respectively arranged at the two ends of the support plate 1, and the two fixing plates 2 can be respectively attached to the two main beams.

The connecting piece passes through the adjustment hole 21 and is connected to the main beam. Specifically, a plurality of cable brackets are installed on the ship for erecting and supporting cables, and a through piece is arranged between each two adjacent cable brackets. The main function of the through piece is to ensure the continuity and safety of cable wiring, reduce stress, protect the integrity of the cable, and provide maintenance convenience, shock absorption and stability. The support plate 1 is installed between the two main beams through the fixing plates 2 set at both ends. The fixing holes 11 of the support plate 1 are used for cable fixing and tying. The size of the ship cable fixing device is matched based on the spacing between the two main beams, that is, the sum of the thickness of the two fixing plates 2 and the length of the support plate 1 is equal to the width of the cable bracket. Then, the two fixing plates 2 are respectively installed on the corresponding main beams through the connecting piece, that is, the ship cable fixing device is installed at the end of the cable bracket and can be adjusted through the adjustment hole 21. The adjustment hole 21 is a waist-shaped hole. The fixing plate 2 moves synchronously with the connecting piece and the main beam and the support plate 1 along the extension direction of the adjustment hole 21 until the spacing between the corresponding ship cable fixing devices on the two adjacent cable brackets does not exceed the safety distance. The safety distance is set to 400mm. The connecting piece is an adjusting bolt. Tighten the connecting piece to lock and fix the fixing plate 2 with the main beam to avoid the problem that the cable is stretched by its own gravity due to the excessive distance between the brackets supporting the cable, which affects the performance and life of the cable. The installation is simple, saves installation time, reduces on-site workload, and also ensures the smooth progress of the project while improving work efficiency and reducing later maintenance costs.

[0038] Further, continue to refer to Figure 1 There are multiple fixing holes 11, and the multiple fixing holes 11 are extended along the length direction of the support plate 1.

Specifically, there are multiple connectors, and the multiple connectors pass through the corresponding adjustment holes 21 and are fixedly connected to the main beam. When the spacing between the corresponding ship cable fixing devices on two adjacent cable brackets does not meet the safety distance requirements, the multiple connectors are loosened, and the fixing plate 2 moves synchronously with the connectors and the main beam and the support plate 1 along the extension direction of the multiple adjustment holes 21, and then the multiple connectors are tightened in sequence, so that the fixing plate 2 is locked and fixed to the main beam.

[0040] Further, continue to refer to Figure 1 The fixing plate 2 and the support plate 1 are integrally formed. Specifically, the fixing plate 2 and the support plate 1 are integrally formed by casting or the like. Optionally, the fixing plate 2 and the support plate 1 are fixedly connected by welding, and the connection is firm. The fixing plate 2 and the support plate 1 are made of steel material, including stainless steel material or carbon steel material, and have high structural strength.

[0041] Further, continue to refer to Figure 1 The ship cable fixing device further includes a protective layer, which is coated on the outer surface of the support plate 1 and the fixing plate 2. Specifically, the protective layer includes but is not limited to a pearl surface, a frosted surface, a brushed surface, an embossed surface, etc., through galvanizing, spraying and other technologies, and the outer surface of the support plate 1 and the fixing plate 2 is coated with a protective layer, which has good corrosion resistance while ensuring structural strength.

[0042] Further, continue to refer to Figure 1 The fixing plate 2 is also provided with a grounding hole 22, which is connected to the hull structure through a grounding wire.

[0051] When the requirement that the spacing between the corresponding ship cable fixing devices on two adjacent cable brackets does not exceed the safety distance of 400mm is met, tighten the connector to lock and fix the fixing plate 2 to the main beam. Finally, the hull structure is grounded through the grounding hole 22 to avoid the problem that the cable is stretched by its own gravity due to the large distance between the adjacent brackets supporting the cable, which affects the performance and life of the cable. The installation is simple, saves installation time, reduces on-site workload, and also ensures the smooth progress of the project while improving work efficiency and reducing subsequent maintenance costs.
