Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable construction devices, and particularly relates to a cable laying ship. BACKGROUND

[0002] The cable laying ship, also known as a "cable laying ship" or a "cable laying ship", is a special ship specially used for laying cables on the seabed and underwater. The device for storing cables on the cable laying ship is a cable reel. For example, a combined type submarine cable untwisting system for multiple section submarine cables is disclosed in Chinese patent CN108275503A, which comprises a submarine cable storage reel and a plurality of liftable load-bearing tables arranged below the submarine cable storage reel. The submarine cable storage reel comprises an inner fence, an outer fence, a bottom plate and a partition plate. The inner fence, the outer fence and the bottom plate are matched to form an upwardly open cable storage cavity. The partition plate is transversely arranged to divide the cable storage cavity into multiple layers of cable storage chambers. Although the submarine cable storage reel has multiple layers of cable storage chambers, when the cable is discharged from a single cable storage chamber, the entire submarine cable storage reel will rotate, which makes the rotating force of the submarine cable storage reel larger. Therefore, the existing cable laying ship has the problem of a larger rotating force of the submarine cable storage reel. CONTENT OF THE UTILITY MODEL

The fixed shaft is fixed to the ship body. The fixed shaft is arranged in the first cable reel, and the first cable reel and the fixed shaft are rotatably connected. The support table is fixed to the fixed shaft, and the first cable reel and the support table are rotatably connected. The first driving mechanism is used to drive the first cable reel to rotate. The fixed shaft is arranged in the second cable reel, and the second cable reel and the fixed shaft are rotatably connected. The first cable reel and the second cable reel are arranged apart.

The second bevel gear is arranged on the second cable reel, and the second driving bevel gear is arranged on the ship body. The second bevel gear and the second driving bevel gear are engaged.

[0006] Optionally, the cable laying ship further comprises a first thrust ball bearing and a second thrust ball bearing. The first thrust ball bearing is sleeved on the fixed shaft, and the first cable reel, the first thrust ball bearing and the support table are sequentially abutted. The second thrust ball bearing is sleeved on the fixed shaft, and the second cable reel, the second thrust ball bearing and the ship body are sequentially abutted.

[0007] Optionally, the first cable reel comprises a first bottom plate and a first inner fence, the first bottom plate and the first inner fence are connected, the fixed shaft is arranged through the first bottom plate and the first inner fence, the first bottom plate and the fixed shaft are arranged apart, the first inner fence and the fixed shaft are arranged apart, and the first bottom plate and the race of the first thrust ball bearing are fixedly connected.

[0045] The present application is explained by specific embodiments, and other advantages and effects of the present application can be easily understood by those skilled in the art from the disclosure of the present application.

[0046] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. In order to enable those skilled in the art to better understand the present application scheme, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.

[0047] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or devices.

[0048] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0049] like Figure 1 As shown, this embodiment provides a cable-laying vessel, comprising a fixed shaft 6, a hull 7, a first cable reel 1, a support platform 3, a first drive mechanism 14, a second cable reel 4, and a second drive mechanism 15. The fixed shaft 6 is fixed to the hull 7. The fixed shaft 6 passes through the first cable reel 1, and the first cable reel 1 and the fixed shaft 6 are rotatably connected. The support platform 3 is fixed to the fixed shaft 6, and the first cable reel 1 and the support platform 3 are rotatably connected. The first drive mechanism 14 drives the first cable reel 1 to rotate. The fixed shaft 6 passes through the second cable reel 4, and the second cable reel 4 and the fixed shaft 6 are rotatably connected. The first cable reel 1 and the second cable reel 4 are spaced apart. The second drive mechanism 15 drives the second cable reel 4 to rotate.

[0050] like Figure 1 As shown, since both the first cable reel 1 and the second cable reel 4 are rotatably connected to the fixed shaft 6, and the first cable reel 1 and the second cable reel 4 are spaced apart, the first cable reel 1 is driven to rotate by the first drive mechanism 14, and the second cable reel 4 is driven to rotate by the second drive mechanism 15. That is, the first cable reel 1 and the second cable reel 4 can rotate independently. When the first cable reel 1 rotates to release the cable, the second cable reel 4 will not rotate with it, and when the second cable reel 4 rotates to release the cable, the first cable reel 1 will not rotate with it, thus reducing the force required to rotate the submarine cable storage reels.

[0051] like Figure 1The material of the fixed shaft 6 can be 45# steel. The materials of the first cable reel 1 and the second cable reel 4 can be steel. The first cable reel 1 and the second cable reel 4 can store cables of different specifications (the specifications can include size, material, shape, model, etc.).
