Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to an offshore charging cable. Background Art

[0002] Offshore charging cables are mainly used for power transmission between offshore facilities and onshore power sources, or for power transmission between different offshore facilities, such as providing power connection and charging functions for offshore wind farms, oil drilling platforms, floating production storage and offloading units (FPSO), etc. They can also be used for charging ships when they are moored offshore.

[0003] Some shorter offshore charging cables are directly suspended between offshore facilities and onshore power sources when in use. The middle section of the cable will sag below the sea surface under its own weight, making it inconvenient for people to see and making it easy for accidental contact to cause damage. Therefore, it is necessary to propose an offshore charging cable. Utility Model Content

[0004] The purpose of the present utility model is to provide an offshore charging cable to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an offshore charging cable, comprising a cable, the outer portion of the cable is sheathed with a support tube, a rolling assembly is arranged inside the support tube, the lower end of the support tube is fixedly connected to a support rod, the lower end of the support rod is fixedly connected to a rotating ring, a connecting tube is rotatably connected inside the rotating ring, both ends of the connecting tube are fixedly connected to a floating tube, the lower end of the rotating ring is fixedly installed with a connecting rod, and the lower end of the connecting rod is fixedly connected to a downward pressure block.

[0006] Preferably, the rolling assembly includes a ball groove, which is opened on the inner wall of the top end of the support tube, and a ball is rollingly connected in the ball groove.

[0007] Preferably, the lower end of the ball extends into the support tube and abuts against the outer side wall of the cable.

[0008] Preferably, both ends of the rotating ring abut against outer side walls of the two floating cylinders respectively.

[0009] Preferably, the two floating cylinders are connected via a connecting pipe.

[0010] Compared with the prior art, the beneficial effect of the present invention is that when in use, the equipment is slidably connected to the bottom end of the cable through a rolling assembly and first contacts the sea surface, and the floating tube will float on the sea surface, while the downward pressure block will sink below the sea surface under its own weight, and drive the rotating ring to rotate based on the connecting tube, and push the support tube and the cable to the sea surface and support them, so that the cable will not sink completely to the seabed, which is convenient for external identification and avoids accidental damage.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] like Figure 1-Figure 3 As shown, the utility model provides the following technical solutions:

[0017] Example 1: An offshore charging cable, comprising a cable 1, wherein the outer portion of the cable 1 is sheathed with a support tube 2, a rolling assembly is disposed inside the support tube 2, a support rod 3 is fixedly connected to the lower end of the support tube 2, a rotating ring 4 is fixedly connected to the lower end of the support rod 3, a connecting tube 5 is rotatably connected to the rotating ring 4, both ends of the connecting tube 5 are fixedly connected to a floating tube 6, a connecting rod 7 is fixedly mounted on the lower end of the rotating ring 4, and a lower pressure block 8 is fixedly connected to the lower end of the connecting rod 7;

[0018] The rolling assembly includes a ball groove 9, which is opened on the inner wall of the top end of the support tube 2, and a ball 10 is rollingly connected in the ball groove 9;

[0019] When in use, during the laying of the cable 1, the support tube 2 is directly slidably connected to the cable 1 through the ball bearing 10, and slides to the lower end of the cable 1 under its own weight, and contacts the sea surface before the cable 1, and the float 6 will float on the sea surface and support the rotating ring 4 through the connecting tube 5, and the lower pressure block 8 will sink below the sea surface under its own weight and be vertical, and the lower pressure block 8 supports the rotating ring 4 through the connecting rod 7, so that the rotating ring 4 supports the support rod 3 and the support tube 2, and the support tube 2 supports the cable 1 so that it remains on the sea surface. Secondly, when the float 6 rolls and shakes on the sea surface, the connecting tube 5 and the rotating ring 4 are rotatably connected, so that the float 6 will not affect the support of the cable 1, and the falling of the lower pressure block 8 can make the support rod 3 and the support tube 2 maintain an angle to support the cable 1.

[0020] Embodiment 2: This embodiment differs from Embodiment 1 in that the technical solution includes:

[0021] The lower end of the ball 10 extends into the support tube 2 and abuts against the outer wall of the cable 1. The support tube 2 is directly slidably connected to the cable 1 through the ball 10, and slides to the lowermost end of the cable 1 under its own weight. The two ends of the rotating ring 4 respectively abut against the outer walls of the two floating tubes 6, so that the rotating ring 4 can only rotate in place without shaking at will. The two floating tubes 6 are connected by the connecting tube 5, so that the internal gas is connected and will not tip over due to uneven gas.

[0022] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
