[0021] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0022] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0023] Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A self-maintaining stable base for laying submarine cables is shown, comprising an installation base 1 for improving the installation stability of the submarine cable, an external self-cruising detection module 2 is installed on the outside of the installation base 1, and the external self-cruising detection module 2 comprises an external detection cover 21 with an inverted U-shaped structure sleeved on the outside of the installation base 1, a crawler-type travel unit 23 installed on both sides of the external detection cover 21 through a top elevator 22, four electrically controlled detection covers 24 elastically assembled on the inner side of the external detection cover 21, and an electrically controlled cutting module 25 slidably installed on the periphery of the electrically controlled detection cover 24.

[0024] Working principle: The start time is customized through electronic control, and then the external self-cruise detection module 2 is separated from the installation base 1 and moves along the submarine cable. While moving, the electronically controlled detection cover 24 is flipped inward to form a ring-shaped detection mechanism around the submarine cable. Then, during translation, the electronically controlled cutting module 25 can automatically cut off surface impurities when encountering resistance, ensuring that the detection process can proceed smoothly.

[0025] In order to improve the intuitiveness of the top display, the upper end of the external detection cover 21 has an upwardly protruding top boss 3, and a sinking groove is provided on the upper surface of the top boss 3. A waterproof and pressure-proof lampshade 4 with a built-in LED status display light is fixedly installed at the opening position of the upper end of the sinking groove.

[0026] According to the running status and test results, the LED status display light is controlled to start different color status lights. It starts yellow when running, displays red when a fault is detected, displays a flashing yellow light when charging, and lights up green when charging is completed and idle.

[0027] In order to cooperate with automatic control, an electronic level controller 5 for controlling the top elevator 22 is installed on the bottom surface of the sinking groove of the top boss 3.

[0028] The electronic level controller 5 can automatically control the extension of the low-position top lift 22 according to the horizontal state of the external detection cover 21, thereby ensuring the stability of the entire external self-cruise detection module 2.

[0029] In order to cooperate with the external concealed rotation fixation, arc-shaped lateral mounting grooves for installing the top elevator 22 are symmetrically opened on both side walls of the external detection cover 21, and lateral mounting covers 6 for fixing the top elevator 22 are bolted on both side walls of the external detection cover 21.

[0030] In order to cooperate with the drive, the crawler travel unit 23 includes a lifting frame 231 fixedly installed on the lower protruding end of the top lift 22, an electric drive wheel 232 installed on the outside of the lifting frame 231, a driven wheel 233 and a flexible crawler 234.

[0031] The top lift 22 controls the lifting frame 231 to be raised and lowered by telescoping, and then the flexible track 234 is sleeved on the outside of the electric drive wheel 232 and the driven wheel 233. The electric drive wheel 232 is used to control the flexible track 234 to move, thereby controlling the entire external self-cruise detection module 2 to be driven.

[0032] In order to facilitate lateral storage, arc-shaped storage grooves are provided on the inner side of the external detection cover 21 at positions corresponding to the electrically controlled detection cover 24 .

[0033] In order to cooperate with flip control and detection, the electrically controlled detection cover 24 includes a flip adjustment arm 241 movably installed at the opening position of the arc-shaped storage groove, an arc-shaped cover shell 242 fixedly installed at the flip end of the flip adjustment arm 241, a temperature detection module 243 installed inside the arc-shaped cover shell 242, a surface defect detection module 244, and an electrically controlled support rod 245 movably installed inside the arc-shaped storage groove.

[0034] The electric control strut 245 controls the flip adjustment arm 241 by extending and retracting, thereby flipping the arc-shaped cover 242 toward the outside of the submarine cable, forming a ring frame around the submarine cable. The temperature detection module 243 and the surface defect detection module 244 inside the arc-shaped cover 242 then perform optical scanning on the surface of the submarine cable to determine the temperature and damage level, respectively. The scanning method is conventional. When abnormal temperature or surface damage is detected at the location, the external self-cruise detection module 2 will stop and transmit the internal wireless signal to the nearest installation base 1. The location signal and the cause of the fault will be transmitted to the remote terminal through the communication unit inside the installation base 1, and then manual repair operations will be performed; If damage occurs, the arc-shaped cover 242 can be covered on the surface of the submarine cable, and then closed to improve the sealing of the damaged position while waiting for manual work.

[0035] The arc-shaped covers 242 at adjacent positions are arranged in a staggered layout, so that they can be suitable for submarine cables with different diameters.

[0036] In order to cooperate with the magnetically controlled reciprocating cutting, the electrically controlled cutting module 25 includes an external guide frame 251 fixed on the outer surface of the arc-shaped cover shell 242, a cutting blade 252 slidingly sleeved on the external guide frame 251, a magnetically controlled reciprocating control module 253 and a pressure control module 254 installed between the external guide frame 251 and the cutting blade 252.

[0037] The magnetically controlled reciprocating control module 253 includes electromagnets installed on the inner walls on both sides of the external guide frame 251 and iron springs controlled by the electromagnets. The electromagnets on both sides are opened and closed at intervals to control the iron springs to be adsorbed, folded and unfolded. In this way, the iron springs can control the cutting blade 252 to slide and adjust on the outside of the external guide frame 251. The starting method of the magnetically controlled reciprocating control module 253 is controlled by the pressure control module 254. When impurities on the surface of the submarine cable squeeze the cutting blade 252, the pressure control module 254 will be squeezed at this time, and then the pressure control module 254 will start the magnetically controlled reciprocating control module 253.

[0038] In order to cooperate with magnetic positioning, the outer side surface of the mounting base 1 and the inner side surface of the external detection cover 2 are fixedly equipped with mutually cooperating magnetic control positioning modules 7.

[0039] In order to complement the external self-cruise detection module 2 , a wireless charging module 8 that cooperates with each other is fixedly mounted on the inner upper end of the mounting base 1 and the inner top surface of the external detection cover 2 .

[0040] After the external self-cruise detection module 2 performs detection and cruising along the submarine cable, when the external self-cruise detection module 2 moves to the outside of the mounting base 1, the magnetic control positioning module 7 senses that the external self-cruise detection module 2 has reached the designated area, and the magnetic control positioning module 7 automatically controls the wireless charging module 8 to start and supply energy to the battery inside the external self-cruise detection module 2.

[0041] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
