Description

Technical Field

[0001] The utility model belongs to the field of military cable brackets, in particular to a single-hole cable vibration damper for ships. Background Art

[0002] Shipboard military cables are composed of one or more mutually insulated conductive core wires placed in a closed sheath, which can be covered with a protective layer on the outside and laid on the seabed. These cables are used to transmit 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 shipboard cables will also vary depending on the specific ship type, power requirements and electrical system design.

[0003] Prior art technology exposes shipboard military cables to significant impact and vibration during navigation. Prolonged vibration can easily cause the cables to become detached or loosen at the interfaces with electrical equipment, resulting in poor contact and potentially causing safety incidents. Furthermore, most seismic-resistant cable trays are suitable only for laying cables; they cannot be used to secure cable conduits, providing no shock-absorbing effect. Furthermore, submarines have very stringent vibration and noise requirements. The vibration waves from submarine cables, transmitted to the bulkhead, can negatively impact the submarine's quietness. Utility Model Content

[0004] The utility model aims to overcome the shortcomings of the existing technology and provide a single-hole cable vibration damper for ships that has a simple structure, is easy to install, is easy to adjust vibration damping parameters, and can simultaneously meet the vibration damping requirements of both directions in the vertical plane of the cable and the axial direction of the cable.

[0005] In order to solve the above technical problems, the utility model is achieved as follows:

[0006] A single-hole cable vibration damper for ships comprises an outer frame, a rubber body and a bottom plate; the rubber body comprises a single-hole center ring and support feet fixed to the outer wall of the single-hole center ring; the bottom plate is connected to the bottom of the outer frame; the rubber body is fixedly connected to the inner wall of the outer frame and the bottom plate via the support feet.

[0007] Furthermore, the utility model is also provided with welding feet; a folding edge is fixedly provided at the bottom of the outer frame; and the outer frame is detachably connected to the bottom plate and the welding feet via the folding edge.

[0008] Furthermore, the outer frame of the present invention adopts a flange structure; the end of the supporting foot is fixedly placed in the flange of the outer frame.

[0009] Furthermore, a cutout is provided on the upper portion of the single-hole center ring in the rubber body of the present invention.

[0010] Furthermore, the outer frame of the present invention is connected to the bottom plate and the welding feet through the folding edge and the bolts.

[0011] Furthermore, the utility model has four supporting legs, which are evenly distributed on the outer wall of the single-hole center ring.

[0012] To avoid sonar detection, ships, especially submarines, have very strict vibration and noise control requirements. It has been found that the vibration of submarine cables is not negligible. This vibration is transmitted to the bulkhead, affecting the submarine's quietness. The present invention has a simple structure, is easy to install, and allows for easy adjustment of vibration reduction parameters. It can also meet the vibration reduction requirements in both the vertical direction and the axial direction of the cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] like Figure 1 、 2 As shown in Figure 3, the single-hole cable shock absorber for ships includes an outer frame 1, a rubber body 2 and a bottom plate 3; the rubber body 2 includes a single-hole center ring and a support foot 5 fixed to the outer wall of the single-hole center ring; the bottom plate 3 is connected to the bottom of the outer frame 1; the rubber body 2 is fixedly connected to the inner wall of the outer frame 1 and the bottom plate 3 through the support foot 5. The utility model is also provided with a welding foot 4; a folding edge is fixedly provided at the bottom of the outer frame 1; the outer frame 1 is detachably connected to the bottom plate 3 and the welding foot 4 through the folding edge. The outer frame 1 adopts a flanging structure; the end of the support foot is fixedly placed in the flanging 6 of the outer frame 1. A cutout 7 is provided on the upper part of the single-hole center ring in the rubber body 2. The outer frame 1 is connected to the bottom plate 3 and the welding foot 4 through the folding edge by bolts 8. There are four support feet 5, and they are evenly distributed on the outer wall of the single-hole center ring.

[0019] During specific use, the cable of the utility model passes through the single-hole center ring of the rubber body 2, and multiple cables are arranged along the axial direction of the cable to achieve the purpose of vibration reduction. The rubber body 2 of the utility model can better meet the requirements of vibration reduction stiffness and damping and has good wrapping properties. It can not only provide vibration reduction in two directions in the vertical plane, but also meet the axial vibration reduction requirements of the cable through the preload force provided by the interference fit between the single-hole center ring and the cable. The outer frame 1 of the utility model adopts a flanging structure to ensure the stable position of the rubber body in three directions, and is connected to the bottom plate 3 to jointly constrain the rubber. At the same time, the flanging structure has an overload protection function. When the cable is subjected to a large load, it contacts the flanging 6 to prevent it from moving, thereby preventing the rubber body 2 from being damaged due to excessive deformation. The bottom folding edge of the outer frame 1 of the utility model is connected to the bottom plate 3 and the welding foot 4, and has good processability. See Figure 1 As shown, the single-hole center ring of the rubber body 2 of this invention has a cutout 7 on the top for cable placement, thus ensuring a bottom-up assembly sequence and facilitating installation. The entire device is welded to the bottom surface via weld legs 4, making installation easy and overall stability more stable. This device occupies a relatively small space, and due to its strict space requirements, it can effectively reduce cable vibration in confined spaces.
