Description

Technical Field

[0001] This utility model relates to the field of cable protection equipment technology, and in particular to an online monitoring system for the status of submarine cables. Background Technology

[0002] Submarine cables are laid between offshore substations and land, and between wind turbines and offshore substations. The online monitoring system for the status of submarine cables needs to inspect these cables.

[0003] A search revealed a Chinese patent disclosure for an online monitoring system for submarine cable status (authorization announcement number CN212082451U), comprising a submarine cable temperature and strain monitoring module, a submarine cable disturbance monitoring module, a ship 3D stereoscopic monitoring module, a submarine cable spare fiber monitoring module, a GIS module, and a fault alarm module. The submarine cable disturbance monitoring module consists of an optical fiber signal feedback system designed based on a combination of laser interferometry and Φ-OTDR principles. The ship 3D stereoscopic monitoring module comprises an AIS automatic identification system, a long-range radar system, a high-frequency radio, a video system, stereoscopic monitoring buoys, a remote broadcasting system, searchlights, and positioning beacons. This patented technology not only possesses the functions of real-time online distributed monitoring of temperature and strain, real-time online disturbance monitoring, and real-time AIS radar video for 3D stereoscopic monitoring of vessels in the submarine cable warning zone, but also has a good warning function, providing excellent monitoring of the cable status and effectively ensuring the safety of submarine cable lines.

[0004] However, the above-mentioned device still has some drawbacks in actual use. The most obvious one is that the above-mentioned submarine cable status online monitoring system achieves the purpose of monitoring the cable through a floating hull. However, the equipment box, photovoltaic module, lamp holder, warning light, support component, reflective light strip and protective component on the floating hull are all exposed. When there is heavy rain or other bad weather on the sea surface, the various components on the floating hull will be corroded by rainwater for a long time, which will reduce the service life of the components on the floating hull.

[0013] By adopting the above technical solution, the screw can be rotated by controlling the drive source of the screw through the controller, which in turn can drive the threaded block to slide in the fixed groove.

A light intensity sensor is fixedly installed on the outer side of the photovoltaic frame.

[0015] By adopting the above technical solution, the rotation of the output shaft of the servo motor can drive the screw to rotate.

[0016] In one preferred embodiment, a servo motor is fixedly installed inside one of the mounting slots, and the output shaft of the servo motor is fixedly connected to a bidirectional lead screw.

[0017] By adopting the above technical solution, the rotation of the output shaft of servo motor one can drive the bidirectional lead screw to rotate.

[0018] In a preferred embodiment, an alarm is fixedly installed on the top of each bracket, a reflective strip is fixedly connected to the outside of the marine monitoring vessel, and a battery box and an inverter are installed inside the bracket.

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] Reference Figure 1-4An online monitoring system for submarine cables includes a cable temperature monitoring module 111, a cable breakdown fault response module 112, a cable surrounding environment monitoring module 113, a marine monitoring hull 114, a cable environment display module 115, and a cable GIS module 116. Two brackets 12 are fixedly installed on the top of the marine monitoring hull 114. A wireless transceiver 1 is fixedly installed on the top of the marine monitoring hull 114, and a controller is fixedly installed on the top of the marine monitoring hull 114, located to one side of the wireless transceiver 1. Adjustment mechanisms are provided inside each bracket 12, and protective mechanisms are provided at both ends inside the marine monitoring hull 114. The combined use of the submarine cable temperature monitoring module 111, the submarine cable breakdown fault response module 112, the submarine cable surrounding environment monitoring module 113, the marine monitoring vessel 114, the submarine cable environment display module 115, and the submarine cable GIS module 116 enables remote control of the marine monitoring vessel 114, thereby controlling the position of the marine monitoring vessel 114. The submarine cable breakdown fault response module 112 can monitor submarine cable faults and promptly locate and troubleshoot the fault points of the submarine cable. The submarine cable environment display module 115 can transmit the monitoring images on the marine monitoring vessel 114 to the monitoring center to achieve the purpose of remote monitoring.

[0032] Reference Figure 2 The protective mechanism includes mounting slots 2 located at both ends inside the hull of the marine monitoring vessel 114. One mounting slot 2 is rotatably connected to a bidirectional lead screw 3, and the other mounting slot 2 is fixedly connected to a positioning rod 4. Both ends of the bidirectional lead screw 3 are threadedly connected to U-shaped frames 8, which are slidably connected to the positioning rod 4. By rotating the bidirectional lead screw 3, the two U-shaped frames 8 can be driven to move in opposite directions, thereby enabling the rain shelter 6 outside the U-shaped frames 8 to unfold. This prevents the various components on the marine monitoring vessel hull 114 from being corroded by rain or severe weather, thus providing protection for the components on the marine monitoring vessel hull 114 and improving the service life of the components on the marine monitoring vessel hull 114.

[0033] Reference Figure 1 The protective mechanism also includes self-cleaning glass 5 fixedly connected to both ends of the top of the marine monitoring vessel 114. Each of the two self-cleaning glass 5 has a U-shaped storage groove 7 on the side that is close to each other. The inner wall of the storage groove 7 is fixedly connected to a rain shelter 6. The side of the rain shelter 6 away from the self-cleaning glass 5 is fixedly connected to a corresponding U-shaped frame 8. When the U-shaped frame 8 is pulled, the rain shelter 6 in the storage groove 7 will be pulled out. The function of the storage groove 7 is to store the rain shelter 6, thereby providing storage space for the rain shelter 6.

[0034] Reference Figure 3The adjustment mechanism includes fixed grooves 18 on both sides of the bracket 12. Screws 19 are rotatably connected inside each fixed groove 18. Threaded blocks are threaded to the outer sides of each screw 19, and connecting rods 17 are rotatably connected to the outer sides of each threaded block. Photovoltaic frames 14 are rotatably mounted on both sides of the bracket 12. Photovoltaic panels 15 are fixedly installed inside each photovoltaic frame 14. The end of the connecting rod 17 away from the threaded block is fixedly connected to the corresponding photovoltaic frame 14. Through the setting of the illuminance sensor 16, the angle of sunlight can be detected and transmitted to the controller. The controller then controls the drive source of the screw 19 to rotate, causing the threaded blocks to slide within the fixed grooves 18. This allows the connecting rods 17 to automatically adjust the angles of the photovoltaic frames 14 and photovoltaic panels 15, thereby improving the absorption rate of sunlight by the photovoltaic panels 15.

[0035] Reference Figure 3 Servo motor 20 is fixedly installed at the bottom of the inner wall of the fixed groove 18. The output shaft of servo motor 20 is fixedly connected to the corresponding screw 19. Illuminance sensor 16 is fixedly installed on the outer side of photovoltaic frame 14. The rotation of the output shaft of servo motor 20 can drive the screw 19 to rotate, thereby realizing the transmission of power.

[0036] Reference Figure 2 One of the mounting slots 2 has a servo motor 11 fixedly installed inside. The output shaft of the servo motor 11 is fixedly connected to the bidirectional lead screw 3. The rotation of the output shaft of the servo motor 11 can drive the bidirectional lead screw 3 to rotate.

[0037] Reference Figure 2 Alarms 13 are fixedly installed on the top of each bracket 12. Reflective strips 10 are fixedly connected to the outside of the marine monitoring vessel 114. A battery box and an inverter are installed inside the bracket 12. The inverter can convert DC power into AC power and store it inside the battery box for use by the electrical equipment on the marine monitoring vessel 114.

[0038] Reference Figure 3 Two marine electric propellers 9 are fixedly installed on the rear side of the marine monitoring vessel 114. The threaded blocks are slidably connected to the inner wall of the corresponding fixed groove 18. The steering and speed of the marine monitoring vessel 114 can be adjusted by the marine electric propellers 9.

[0039] Working principle: First, the servo motor 11 is started, driving the bidirectional lead screw 3 to rotate. The rotation of the bidirectional lead screw 3 causes the two U-shaped frames 8 to move in opposite directions, thereby unfolding the rain shelter 6 outside the U-shaped frames 8. This prevents the various components on the marine monitoring vessel hull 114 from being corroded by rain or severe weather, thus providing protection for the components and extending their service life. When the U-shaped frames 8 are pulled, the rain shelter 6 is pulled out from the storage slot 7. The storage slot 7 also serves to store the rain shelter 6, providing protection for it. The storage space, through the combined use of the submarine cable temperature monitoring module 111, submarine cable breakdown fault response module 112, submarine cable surrounding environment monitoring module 113, marine monitoring hull 114, submarine cable environment display module 115 and submarine cable GIS module 116, enables remote control of the marine monitoring hull 114, thereby controlling the position of the marine monitoring hull 114. The submarine cable breakdown fault response module 112 can monitor submarine cable faults and locate and troubleshoot the fault points of the submarine cable in a timely manner. The submarine cable environment display module 115 can transmit the monitoring images on the marine monitoring hull 114 to the monitoring center to achieve the purpose of remote monitoring.

[0040] By setting up the illuminance sensor 16, the angle of sunlight can be detected and the information is transmitted to the controller. The controller then controls the drive source of the screw 19 to operate, which drives the screw 19 to rotate. This causes the threaded block to slide in the fixed groove 18, and the angle of the photovoltaic frame 14 and the photovoltaic panel 15 can be automatically adjusted by the connecting rod 17 to improve the absorption rate of sunlight by the photovoltaic panel 15. The inverter can convert the DC power into AC power and store it in the battery box for use by the electrical equipment on the marine monitoring vessel 114.
