[0002] Submarine cables are cables wrapped in insulating material and laid on the seabed, mainly used in important applications such as long-distance island connections and cross-sea facilities. To improve the long-term operational stability of submarine cables, manual maintenance and inspection are required. However, to facilitate the inspection and repair of the cable surface, a large amount of maintenance equipment and consumables need to be carried. This equipment and consumables are mostly transported manually. This operation not only consumes a lot of manpower and resources, but it is also very difficult to operate by a single person. This leads to a significant increase in labor costs, high operational difficulty, and low efficiency. Summary of the Invention

[0003] The technical problem that this invention aims to solve is that traditional maintenance equipment and consumables are mostly transported manually.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] Figure 1 , Figure 2 and Figure 3 The device shown is an electrically controlled conveying auxiliary device for the later maintenance of submarine cables. It includes a top-mounted main frame 1, four lateral lifting clamps 2 and four arc-shaped detection frames 3 symmetrically mounted on both sides of the top-mounted main frame 1, an embedded electrically controlled winch 4 fixedly mounted in the center of the top-mounted main frame 1, an electrically controlled outer flow guiding mechanism 5 movably mounted on the outer arc-shaped surface of the lateral lifting clamps 2, and an electrically controlled surround detection module 6 that cooperates with the arc-shaped detection frames 3 movably mounted on the inner top surface of the top-mounted main frame 1.

[0024] Working principle: When it is necessary to transport goods and consumables, the side lifting clamps 2 clamp the goods and consumables from both sides, and then the electronically controlled outer flow guiding mechanism 5 drives the entire equipment. After moving to the designated position, the clamps are released to transport the goods and consumables to the designated position. It can also follow the maintenance personnel on the seabed for tracking, so that it can be used and replenished at any time. After transportation is completed, the arc-shaped detection frame 3 can be flipped to the outside of the submarine cable to form a ring-shaped detection mechanism. The electronically controlled surround detection module 6 can then perform a surround detection along the outside of the submarine cable, and finally complete the overall detection of the submarine cable by translation.

[0025] To facilitate the movable assembly on both sides, the lower ends of both sides of the top main frame 1 are provided with lateral flipping assembly slots for the movable assembly of the lateral lifting clamping arm 2 and the arc-shaped detection frame 3.

[0026] To accommodate the top mounting and bottom extension of the hoisting cable, the upper surface of the top main frame 1 is provided with an upper mounting groove for mounting the embedded electric winch 4, and the lower surface of the top main frame 1 is provided with a lower rope threading hole that cooperates with the embedded electric winch 4.

[0027] The bottom of the internal lifting cable of the embedded electric winch 4 is connected to a flip-up hook, which facilitates lifting.

[0028] To facilitate electric tilting and external flow guidance, the lateral lifting clamp 2 has an arc-shaped mounting port 7 for installing the electrically controlled external flow guidance mechanism 5. The electrically controlled external flow guidance mechanism 5 includes a tilting flow guide seat 51 movably installed inside the arc-shaped mounting port 7, an electrically controlled worm gear 52 for controlling the tilting flow guide seat 51, an electrically controlled flow guide cover 53 movably installed on the outer surface of the tilting flow guide seat 51, and a drive liquid pump 54 installed inside the electrically controlled flow guide cover 53.

[0029] On one side of the rotating guide seat 51, there is a lateral worm wheel that cooperates with the electric worm gear 52. The electric worm gear 52 drives the lateral worm wheel to rotate, thereby controlling the rotating guide seat 51 to rotate in the arc-shaped assembly port 7, thereby changing the angle of the rotating guide seat 51. The electric guide cover 53 can rotate along the rotating guide seat 51.

[0030] When the electric worm gear 52 drives the flipping guide seat 51 to flip and adjust inside the arc-shaped assembly port 7, it can ensure the stability of the device lifting and lowering when the lateral lifting clamp arm 2 is flipped. For example, when the lateral lifting clamp 2 flips upward, the flipping guide seat 51 flips downward; the forward, backward, left, and right translation is controlled by the speed difference between the two sides; The electrically controlled flow guide shroud 53 rotates along the flip flow guide seat 51, so that it can be clamped around the submarine cable by the top main frame 1 and the lateral lifting clamp arm 2. At this time, the electrically controlled flow guide shroud 52 can be rotated to control the entire device to move and adjust along the submarine cable.

[0031] To facilitate internal sliding adjustment, matching arc-shaped guide grooves 8 are provided on the inner top surface of the top-mounted main frame 1 and the inner arc-shaped surface of the arc-shaped detection frame 3.

[0032] To facilitate electronic adjustment and optical inspection, the electronically controlled surround inspection module 6 includes a horizontal assembly frame 61, electric drive wheels 62 mounted on both sides of the horizontal assembly frame 61, elastic limit wheels 63 elastically mounted on both sides of the horizontal assembly frame 61, and an optical inspection module 64 mounted on the side wall of the horizontal assembly frame 61.

[0033] The elastic limiting wheel 63 consists of an elastic support rod fixed to the side wall of the horizontal assembly frame 61 and a limiting wheel installed at the extended end of the elastic support rod. The elastic support rod elastically compresses the limiting wheel, thereby increasing the compressive force between the electric drive wheel 62 and the inner wall of the arc-shaped guide groove 8, thus ensuring drive stability.

[0034] To facilitate cleaning of the submarine cable surface, a scraper is installed on the outside of the horizontal assembly frame 61. At this time, the electric drive wheel 62 drives the horizontal assembly frame 61 to perform circular operation adjustment between the top main frame 1 and the lateral lifting clamp 2. While rotating, surface impurities are scraped off and optical inspection is performed.

[0035] In order to cooperate with the lifting of the submarine cable and ensure the cable is in the center position, the lateral lifting clamp arm 2 is equipped with a magnetically controlled bottom guide wheel 9.

[0036] The lateral lifting clamping arm 2 clamps from both sides and inserts its bottom end into the bottom of the submarine cable. Then, the magnetically controlled bottom guide wheels 9 at the upper and lower ends are activated. At this time, the magnetically controlled bottom guide wheels 9 can be evenly arranged around the submarine cable, which can also reduce the resistance when the equipment is transported along the submarine cable.

[0037] In order to control the angle of the lateral lifting clamp 2 and the arc-shaped detection frame 3, the top main frame 1 is equipped with electrically controlled adjusting support rods 10 on both sides for controlling the flipping of the lateral lifting clamp 2 and the arc-shaped detection frame 3.

[0038] The electrically controlled adjustable support rod 10 controls the lateral lifting of the clamping arm 2 and the arc-shaped detection frame 3 to flip by extending and retracting.

[0039] The top-mounted main frame 1 has lateral assembly frames on both sides for mounting the electrically controlled adjustment support rod 10. The extended end of the electrically controlled adjustment support rod 10 is movably assembled with the lateral lifting clamp arm 2 and the outer arc surface of the arc-shaped detection frame 3.

[0040] The function of the lateral lifting clamp 2 is to clamp and fix consumables or equipment, and then use the electrically controlled outer flow guiding mechanism 5 on the outside of the lateral lifting clamp 2 to control the movement of the entire equipment inside the water body, including translation and lifting.

[0041] When the arc-shaped detection frame 3 approaches the submarine cable, it first flips outward. Then, when the top main frame 1 moves to the upper end of the submarine cable, the arc-shaped detection frames 3 on both sides flip downward to the outer perimeter of the submarine cable, forming a ring-shaped guide mechanism with the top main frame 1 and the arc-shaped detection frames 3 on both sides. The arc-shaped guide groove 8 on the inner top surface of the top main frame 1 and the inner arc-shaped surface of the arc-shaped detection frame 3 forms a ring-shaped guide groove. Then, the electric drive wheel 62 starts and moves along the arc-shaped guide groove 8. At this time, it can move along the outer perimeter of the submarine cable. The optical detection module 64 detects the damage, temperature and distance on the surface of the submarine cable and records them. This can assist maintenance personnel in performing fixed-point maintenance. Damage refers to surface damage or scratches, temperature refers to the operating temperature, and distance refers to the outer diameter of the submarine cable, thereby judging the service status of the submarine cable.

[0042] To facilitate remote control, a front mounting groove 11 is provided on the outer wall of the front end of the top-mounted main unit 1, and an angle-adjustable camera 12 is movably mounted inside the front mounting groove 11.

[0043] The installation method of the angle-adjustable camera 12 is the same as that of drone gimbal cameras on the market, which is convenient for operation and control and can also improve the video acquisition range. The front mounting groove 11 has an opening on the outside and a transparent waterproof cover, which can improve the safety and stability of the angle-adjustable camera 12.

[0044] Remote operators can easily operate and control the system remotely via the angle-adjustable camera 12.

[0045] To facilitate magnetic adjustment, the magnetically controlled bottom guide wheel 9 includes an arc-shaped flip arm 91 movably mounted on the outer side of the lateral lifting clamp arm 2, an electromagnet 92 fixed inside the lateral lifting clamp arm 91, a compression spring 93 elastically mounted between the arc-shaped flip arm 91 and the lateral lifting clamp arm 2, and a bottom guide wheel 94 movably mounted on the flip end of the arc-shaped flip arm 91.

[0046] When the lateral lifting clamp 2 flips downwards to both sides of the submarine cable, the lower end of the arc-shaped flipping arm 91 is inserted into the bottom of the submarine cable. Then, the electromagnet 92 is activated to control the magnetic attraction of the compression spring 93, and simultaneously control the arc-shaped flipping arm 91 to flip towards the lateral lifting clamp 2. At this time, the bottom guide wheel 94 will press against the surface of the submarine cable, forming four guide wheels around the submarine cable. Then, the drive liquid pump 54 drives the submarine cable to move along the submarine cable while it is being lifted. During the movement, inspection can be carried out, and the surface of the submarine cable can be cleaned to facilitate manual inspection.

[0047] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
