Description

Technical Field

[0001] The utility model belongs to the technical field of cable laying, and in particular relates to a submarine cable shock absorbing component and a flexible cable shock absorbing bracket. Background Art

[0002] Submarines use power cables as an important part of the power transmission and distribution system. These cables are used to transfer electricity from the generator room to various ship systems, equipment and devices to meet the power supply needs of various electrical equipment on board. The specifications, cross-sectional area and material selection of ship cables will also vary depending on the specific ship type, power requirements and electrical system design. Submarine cables are generally composed of multi-core cables, each of which is used to transmit different power or signals. These cables are usually composed of copper conductors, insulation layers, sheaths and outer sheaths to meet the requirements of submarine electrical systems. However, in the prior art, existing submarine cables are susceptible to large impact forces and shaking during the ship's travel. Long-term shaking can easily cause the submarine cable to fall off or loosen at the interface with the electrical equipment, resulting in poor contact and inducing safety accidents.

[0003] Chinese patent CN1945083A discloses an integrally raised stretched cable bridge for ships and marine engineering, including a support plate and a guide plate, which is characterized in that the support plate and the guide plate are an integrated ladder structure, and each section of the concave and convex surface of the support plate after the integral stamping process is provided with a reinforcing rib, the upper corners of the guide plates at both ends of the cable bridge are "R" shaped, and the connection between the guide plate and the support plate is also "R" shaped and forms a reinforcing rib, and the side wall of the guide plate is also provided with continuous and regular connecting holes. Compared with the prior art, the present invention adopts an integral stamping process, so that the guide plate and the support plate of the bridge do not need to be welded into one. The above cable bridge does not consider the internal shock and noise reduction factors of the ship. At present, there is no relevant data reported on submarine cable vibration reduction, but for other cable vibration reduction forms, generally a fixed ring is used to cover the cable, and then a vibration reduction device is arranged at the bottom of the fixed ring. The above technical solution has a complex structure, and it is difficult to meet the vibration reduction requirements of the cable in two directions and multiple cables at the same time, and it is inconvenient to adjust the parameters of the vibration reduction device. Utility Model Content

[0004] The utility model aims to overcome the shortcomings of the prior art and provide a submarine cable shock absorbing assembly and a flexible cable shock absorbing bracket which have a simple structure, convenient maintenance, stable structure, adjustable vibration reduction device parameters, ideal shock absorption and noise reduction effects, and an overload protection function.

[0005] To solve the above technical problems, the utility model is implemented as follows:

[0006] A submarine cable shock-absorbing assembly comprises a hanging plate, a T-shaped hanging plate and a shock-absorbing rubber sheet; a supporting plate is transversely fixed at the bottom of the T-shaped hanging plate; the shock-absorbing rubber sheet is fixed between the hanging plate and the T-shaped hanging plate and is located above the supporting plate; an assembly hole is provided at the upper part of the T-shaped hanging plate; and mounting holes are provided on both sides of the hanging plate.

[0007] Furthermore, the utility model provides a hook on the hanging plate; and a through hole is provided on the T-shaped hanging plate corresponding to the position of the hook.

[0008] Furthermore, the utility model provides a screw hole in the middle area of ​​the T-shaped hanging plate; the screw is fixedly connected to the shock-absorbing rubber sheet through the screw hole.

[0009] A flexible cable shock-absorbing bracket comprises a cable bracket and a submarine cable shock-absorbing assembly; the submarine cable shock-absorbing assembly comprises a hanging plate, a T-shaped hanging plate and a shock-absorbing rubber sheet; a supporting plate is fixedly arranged horizontally at the bottom of the T-shaped hanging plate; the shock-absorbing rubber sheet is fixedly arranged between the hanging plate and the T-shaped hanging plate and is located above the supporting plate; an assembly hole is arranged on the upper part of the T-shaped hanging plate; mounting holes are arranged on both sides of the hanging plate; the hanging plate in the submarine cable shock-absorbing assembly is fixedly connected to the cable bracket through the mounting holes.

[0010] The utility model has the advantages of simple structure, convenient maintenance, stable structure, adjustable parameters of vibration reduction device, ideal vibration reduction and noise reduction effect, and overload protection function. The vibration reduction static stiffness of the utility model can be achieved by adjusting different installation positions of the cable shock absorbing component.

[0011] Compared with the prior art, the utility model has the following characteristics:

[0012] a. The different installation positions of the cable damping assembly on the cable bracket can meet the vibration reduction requirements of cables of different qualities. At the same time, with the help of the optimization function of the finite element, its configuration can be optimized for easy implementation.

[0013] b. This cable shock-absorbing assembly realizes the vibration reduction requirements of the cable in the transverse, axial and longitudinal directions.

[0014] c. This cable shock-absorbing assembly can meet the technical requirements for simultaneous vibration reduction of multiple cables.

[0015] d. This cable shock-absorbing assembly occupies a small space, which meets the extremely narrow installation environment of submarines.

[0016] e. This cable shock-absorbing component has an overload protection function. When the cable is subjected to a large inertial force, it is prevented from continuing to move, thus preventing the shock-absorbing rubber sheet from being damaged due to excessive compression.
