Description

Technical Field

[0001] This invention relates to the field of submarine cable post-maintenance adjustment technology, and in particular to a conveying and adjusting mechanism applied to submarine cable post-maintenance devices. Background Technology

[0002] Submarine cables are cables wrapped in insulating material and laid on the seabed, mainly used in critical applications such as long-distance connections between islands and cross-sea facilities. The routine maintenance of submarine cables requires significant manpower and resources. Furthermore, relying solely on manpower makes long-distance underwater operations impossible, greatly increasing the maintenance cycle and difficulty. This results in long maintenance intervals, compromising the durability and timeliness of repairs. Existing cleaning equipment cannot operate unmanned or adjust the position of submarine cables, and it cannot perform comprehensive inspection and maintenance of exposed and contact surfaces. Summary of the Invention

[0003] The technical problem to be solved by this invention is that the maintenance of submarine cables on the market is difficult and costly. At the same time, traditional cleaning equipment cannot be operated unmanned or adjusted in position on the submarine cables laid on the seabed, and cannot perform comprehensive inspection and maintenance on their exposed and contact surfaces.

[0004] The technical solution adopted by this invention to solve its technical problem is: a conveying and adjusting mechanism applied to a submarine cable post-maintenance device, including an arc-shaped top mounting base, arc-shaped lateral tilting adjusting covers movably mounted on both sides of the arc-shaped top mounting base, an electrically controlled top adjusting cover movably mounted on the upper surface of the arc-shaped top mounting base, an electrically controlled flow guiding device movably mounted inside the electrically controlled top adjusting cover, and matching inner guide grooves opened on the inner arc-shaped surfaces of the arc-shaped top mounting base and the arc-shaped lateral tilting adjusting covers, an electrically controlled cleaning roller brush and an electrically controlled detection mechanism movably mounted inside the inner guide grooves of the arc-shaped top mounting base, and a plurality of arc-shaped slag discharge ports matching the electrically controlled cleaning roller brush opened on the outer arc-shaped surface of the arc-shaped lateral tilting adjusting cover.

[0005] The upper surface of the arc-shaped top mounting base is provided with a central storage groove for installing an electrically controlled top adjustment cover, and a flip storage slot is provided on the bottom surface of the central storage groove.

[0006] The electrically controlled top adjustment cover includes a flip-up cover that is movably installed inside the central storage groove and a top flip-up support rod that is movably installed inside the flip-up storage slot.

[0007] The electrically controlled flow guiding device includes a tilting adjustment cover movably mounted inside the tilting cover, an angle adjustment motor mounted at the lower end of the tilting cover, and electrically controlled flow guiding blades mounted on both sides inside the tilting adjustment cover.

[0008] The inner guide groove includes a front guide groove, an outer guide groove, and a rear guide groove.

[0009] The electrically controlled cleaning roller brush includes an internal adjustment seat slidably assembled inside the front guide groove and the rear guide groove, a guide support wheel and an electrically controlled drive wheel movably installed on the side wall of the internal adjustment seat, a built-in drive motor movably installed inside the internal adjustment seat, a cleaning roller brush axially mounted on the drive shaft outside the built-in drive motor via a coupling, an extraction blade axially fixed to one side of the cleaning roller brush, and an air guide cover fixed to the side wall of the internal adjustment seat.

[0010] The electronically controlled detection mechanism includes an external adjustment block that is slidably mounted inside an external guide groove, a fixed frame that is fixed between the external adjustment block and the internal adjustment seat, and an embedded optical detection probe and an infrared temperature measurement module that are fixed inside the external adjustment block.

[0011] The upper surface of the arc-shaped top mounting base is movably fitted with electrically controlled flip-up support rods on both sides for controlling the arc-shaped lateral flip-up adjustment cover.

[0012] A lateral adjustment frame is fixedly mounted on the outer surface of the arc-shaped lateral tilting adjustment cover, and an electrically controlled lifting track is movably mounted inside the lateral adjustment frame.

[0020] 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.

[0021] 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.

[0022] Figure 1 , Figure 2 , Figure 3 and Figure 4 The conveying and adjusting mechanism shown is used in a submarine cable post-maintenance device. It includes an arc-shaped top mounting base 1, arc-shaped lateral tilting adjustment covers 2 movably mounted on both sides of the arc-shaped top mounting base 1, an electrically controlled top adjustment cover 3 movably mounted on the upper surface of the arc-shaped top mounting base 1, an electrically controlled flow guiding device 4 movably mounted inside the electrically controlled top adjustment cover 3, inner guide grooves that cooperate with each other on the inner arc-shaped surfaces of the arc-shaped top mounting base 1 and the arc-shaped lateral tilting adjustment cover 2, an electrically controlled cleaning roller brush 5 and an electrically controlled detection mechanism 6 movably mounted inside the inner guide groove of the arc-shaped top mounting base 1, and a plurality of arc-shaped slag discharge ports 7 that cooperate with the electrically controlled cleaning roller brush 5 on the outer arc-shaped surface of the arc-shaped lateral tilting adjustment cover 2.

[0023] Working principle: The electrically controlled top adjustment cover 3 at the upper end of the arc-shaped top mounting base 1 is flipped and adjusted, while the electrically controlled flow guide device 4 can rotate and adjust along the inside of the electrically controlled top adjustment cover 3. When the electrically controlled flow guide device 4 rotates and is stored inside the electrically controlled top adjustment cover 3, it can be easily stored. When the electrically controlled flow guide device 4 rotates, the two sides of the electrically controlled top adjustment cover 3 can be adjusted.

[0024] The entire mechanism descends to the seabed and aligns with the submarine cable using video cameras mounted on both sides of the arc-shaped top mounting base 1. Then, the arc-shaped lateral tilting adjustment cover 2 is tilted downwards, forming a cylindrical detection frame with the arc-shaped top mounting base 1 and the arc-shaped lateral tilting adjustment cover 2, placing the submarine cable inside. At this point, the electrically controlled detection mechanism 6 is activated, driving in a circular motion along the submarine cable. When contamination is detected on the cable surface, the electrically controlled cleaning roller brush 5 is activated to remove the contaminants. Simultaneously, the removed contaminants are discharged through the outer arc-shaped slag discharge port 7.

[0025] To facilitate top storage and assembly, the upper surface of the arc-shaped top mounting base 1 is provided with a central storage groove 8 for installing the electrically controlled top adjustment cover 2, and a flip storage slot 9 is provided on the bottom surface of the central storage groove 8.

[0026] To facilitate the flip adjustment, the electrically controlled top adjustment cover 3 includes a flip cover 31 that is movably installed inside the central storage groove 8 and a top flip support rod 32 that is movably installed inside the flip storage slot 9.

[0027] To facilitate rotation adjustment, the electrically controlled flow guide device 4 includes a tilting adjustment cover 41 movably mounted inside the tilting cover 31, an angle adjustment motor 42 mounted at the lower end of the tilting cover 31, and electrically controlled flow guide blades 43 mounted on both sides inside the tilting adjustment cover 41.

[0028] Angle adjustment motor 42 controls the tilting adjustment cover 41 to rotate and adjust inside the tilting cover 31, tilting the electrically controlled guide vanes 43 outward. At this time, the electrically controlled guide vanes 43 on both sides rotate to both sides of the arc-shaped top mounting base 1. The electrically controlled guide vanes 43 then rotate rapidly to guide the air downward, controlling the entire adjustment mechanism to rise. When the top tilting support rod 32 extends to control one side of the tilting cover 31 to tilt upward, it can drive forward. When the tilting cover 31 tilts outward, the electrically controlled guide vanes 43 rotate in the opposite direction, thus driving backward. The translation is achieved by using the speed difference of the electrically controlled guide vanes 43 on both sides.

[0029] To facilitate sliding adjustment, the inner guide groove includes a front guide groove 10, an outer guide groove 11, and a rear guide groove 12.

[0030] To facilitate the cleaning and maintenance of the submarine cable surface, the electrically controlled cleaning roller brush 5 includes an internal adjustment seat 51 slidably mounted inside the front guide groove 10 and the rear guide groove 11, a guide support wheel 52 and an electrically controlled drive wheel 53 movably mounted on the side wall of the internal adjustment seat 51, a built-in drive motor 54 movably mounted inside the internal adjustment seat 51, a cleaning roller brush 55 axially mounted on the drive shaft outside the built-in drive motor 54 via a coupling, an extraction blade 56 axially fixed to one side of the cleaning roller brush 55, and an air guide cover 57 fixed to the side wall of the internal adjustment seat 51.

[0031] The electrically controlled drive wheel 53 controls the internal adjustment seat 51 to slide synchronously along the front guide slide 10 and the rear guide slide 11. Through the synchronous and unidirectional sliding adjustment of the internal adjustment seat 51 inside the front guide slide 10 and the rear guide slide 11, the cleaning roller brush 55 is driven to slide along the front guide slide 10 and the rear guide slide 11. The built-in drive motor 54 drives the cleaning roller brush 55 to rotate at high speed. Through centrifugal force, the cleaning roller brush 55 is controlled to clean the surface of the submarine cable. Then, it is brushed away along the outer side of the submarine cable. The centrifugal force generated by the high-speed rotation of the cleaning roller brush 55 causes the cleaning brush on the outer side of the cleaning roller brush 55 to be thrown outward and scraped away from the surface of the submarine cable.

[0032] At the same time, the extraction blades 56 are driven, and the cleaning material generated during cleaning is discharged from the inside to the outside of the arc-shaped slag discharge port 7 through the extraction blades 56 and the air guide cover 57.

[0033] To facilitate linkage adjustment and optical detection, the electronically controlled detection mechanism 6 includes an external adjustment block 61 that is slidably mounted inside the external guide groove 11, a fixed frame 62 that is fixed between the external adjustment block 61 and the internal adjustment seat 51, an embedded optical detection probe 63 that is fixed inside the external adjustment block 51, and an infrared temperature measurement module 64.

[0034] The external adjustment block 61 is fixed to the internal adjustment seat 51 through the fixed frame 62. When the internal adjustment seat 51 is slidably adjusted, it will drive the external adjustment block 61 to adjust in a coordinated manner. During adjustment, the embedded optical detection probe 63 is used to detect impurities and skin damage on the surface of the submarine cable, and the temperature of the submarine cable is detected non-contactly through the infrared temperature measurement module 64.

[0035] In order to adjust the flip and thus control the opening and closing of the lower opening, the upper surface of the arc-shaped top mounting base 1 is movably equipped with electrically controlled flip support rods 13 for controlling the arc-shaped lateral flip adjustment cover 2.

[0036] The electrically controlled tilting support rod 13 controls the tilting adjustment of the arc-shaped lateral tilting adjustment cover 2 by telescoping, thereby controlling the gap adjustment of the lower connecting surfaces of the arc-shaped lateral tilting adjustment cover 2 on both sides. This makes it easy to control the separation or assembly of the entire mechanism from the submarine cable.

[0037] To facilitate driving on the outer bottom, a lateral adjustment frame 14 is fixedly mounted on the outer surface of the arc-shaped lateral tilting adjustment cover 2, and an electrically controlled lifting track 15 is movably mounted inside the lateral adjustment frame 14.

[0038] The lateral adjustment frame 14 has symmetrically arranged longitudinal adjustment slots on its inner walls on both sides. The electrically controlled lifting track 15 includes a lateral adjustment screw installed inside the longitudinal adjustment slot, a lateral mounting plate with internal thread lifting blocks on both sides, an outer electric drive wheel, an outer support wheel, and a flexible track that are movably installed on the side wall of the lateral mounting plate. The outer electric drive wheel drives the flexible track to rotate along the outer electric drive wheel and the outer support wheel. The lateral mounting plate is raised and lowered by rotating the lateral adjustment screw, thereby forming a downwardly protruding track mechanism on both sides of the mechanism. This allows the submarine cable at this position to be lifted, and then the entire adjustment mechanism can be separated from the contact surface between the submarine cable and the seabed.

[0039] To facilitate support and drive of the bottom of the submarine cable, an embedded internal electric drive wheel 16 is installed on the inner arc-shaped surface of the arc-shaped lateral tilting adjustment cover 2.

[0040] The arc-shaped lateral tilting adjustment cover 2 on both sides of the arc-shaped top mounting base 1 flips downward to form a ring cover with a closed bottom. Then the embedded internal electric drive wheel 16 moves to both sides of the lower end of the submarine cable. At this time, the embedded internal electric drive wheel 16 can rotate along the bottom of the submarine cable, thereby controlling the entire mechanism to move and adjust along the submarine cable.

[0041] 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.
