Description

Technical Field

[0001] This invention relates to the field of optical cable maintenance and power replenishment technology, and in particular to a self-power replenishment device for use in optical cable maintenance equipment. Background Technology

[0002] Submarine optical cables are communication cables laid on the seabed, primarily used for transmitting data between distant islands and across sea. To improve the long-term operational stability of these cables, regular manual maintenance and inspection are required. This results in very high maintenance costs and difficulties. Consequently, some unmanned inspection devices have emerged on the market. However, the biggest problem with these devices is their insufficient endurance, still requiring manned vessels on the surface for recharging. This leads to continued high maintenance costs, and the need for manual recharging is cumbersome, time-consuming, and labor-intensive. Summary of the Invention

[0003] The technical problem this invention aims to solve is that the existing unmanned fiber optic cable inspection equipment has insufficient battery life, requiring manned vessels to replenish its power at sea, resulting in high maintenance costs. Furthermore, manual recharging is cumbersome, time-consuming, and labor-intensive.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a self-powered charging device for optical cable maintenance equipment, including a main charging chamber, an outer buoyancy platform for assisting its floating on the water surface is fixedly installed at the lower edge of the main charging chamber, a chamber for installing energy storage batteries is opened inside the outer wall of the main charging chamber, a fixed solar panel for cooperating with the energy storage battery to charge is fixedly installed on the upper surface of the main charging chamber, a split-type flip solar panel is movably assembled on the outer surface of the main charging chamber, an electrically controlled flip-type charging arm is movably assembled on the inner top surface of the main charging chamber, a bottom loading and unloading port is provided on the lower surface of the main charging chamber, and a split-type bottom bearing correction platform for closing the bottom loading and unloading port is provided at the lower end of the main charging chamber.

[0005] The main energy replenishment tank has an outwardly protruding bottom mounting seat at the lower end of its outer side surface. The outer buoyancy platform has an upper fixed mounting groove that mates with the bottom mounting seat. The main energy replenishment tank is bolted to the outer buoyancy platform by inserting the bottom mounting seat into the upper fixed mounting groove.

[0006] The split-type flip solar panel includes a lateral assembly frame fixed to the two side walls of the main energy replenishment compartment, a flip back plate movably installed inside the lateral assembly frame, an inner guide rail fixed to the inner side of the flip back plate, an inner electric control screw movably installed inside the inner guide rail, an inner translation back plate threaded onto the inner electric control screw via two inner threaded blocks, a lateral adjustment support rod for controlling the flip adjustment of the inner guide rail, and a solar auxiliary panel fixed to the outer surface of the flip back plate and the inner translation back plate.

[0007] The electrically controlled tilting power replenishing arm includes two horizontally arranged top beams fixedly installed on the top surface of the main power replenishing chamber, a tilting adjustment arm movably connected to the top beams, a horizontal power replenishing arm fixedly installed at the end of the tilting adjustment arm, a copper conductive sheet elastically assembled on the pressing surface of the horizontal power replenishing arm, and a top adjustment support rod for controlling the tilting adjustment arm.

[0008] The split-type bottom bearing correction platform includes a top guide cylinder fixed to the top surface inside the main energy replenishment chamber, a longitudinally placed electric control screw movably installed inside the top guide cylinder, an internally threaded lifting cylinder threaded onto the outside of the longitudinally placed electric control screw, a flip bearing plate movably installed at the bottom of the internally threaded lifting cylinder, an electric control correction module installed on the flip bearing plate, and a bottom side adjusting support rod for controlling the flip bearing plate to flip.

[0009] The electronically controlled correction module includes a lateral assembly frame installed on the inner wall of the tilting bearing plate and an electronically controlled correction track movably installed inside the lateral assembly frame.

[0010] The electrically controlled corrective track includes an electrically driven wheel, a support guide wheel, and a corrective track installed inside the lateral assembly frame.

[0011] An embedded bottom guide shroud is fixedly installed on the lower surface of the peripheral buoyancy platform. An electrically controlled guide impeller is installed inside the embedded bottom guide shroud. A lateral guide groove is opened on the outer side of the peripheral buoyancy platform, which is connected to the discharge port of the embedded bottom guide shroud.

[0012] A top-mounted dewatering fan is fixedly installed on the top surface of the main recharge chamber to remove water accumulated in the charging section of the unmanned optical cable maintenance equipment.

[0013] The surface of the flip-over support plate is equipped with an electrically controlled drain valve and a pressure sensing module.

[0014] The beneficial effects of this invention are as follows: It employs an unmanned floating energy replenishment method. The external buoyancy platform enables the main energy replenishment chamber to float autonomously on the sea surface. The split-type flip-type solar panels, combined with fixed solar panels and energy storage batteries, generate electricity independently. The electrically controlled flip-type energy replenishment arm inside the main energy replenishment chamber automatically flips and clamps to charge the unmanned optical cable maintenance equipment. This eliminates the need for prolonged manual operation on the sea surface, greatly improving the endurance of the unmanned optical cable maintenance equipment and reducing maintenance costs and operational difficulty. The main energy replenishment chamber, as the main carrier, controls the unmanned optical cable maintenance equipment's transport on the water surface, reducing resistance and energy consumption. The split-type bottom-bearing correction platform supports, lifts, guides, and corrects the position of the optical cable maintenance equipment through bottom lifting and flipping. The closed bottom loading and unloading port enhances the safety of energy replenishment transportation. The embedded bottom guide shield, in conjunction with the electrically controlled guide impeller, achieves autonomous drive and reset, solving the problem of reliance on manual operation for marine self-supply equipment.

Detailed Implementation

[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] Figure 1 , Figure 2 , Figure 3 and Figure 4The self-powered charging device shown is used in optical cable maintenance equipment. It includes a main charging chamber 1, an outer buoyancy platform 2 for assisting the main charging chamber 1 to float on the water surface is fixedly installed at the lower edge of the main charging chamber 1, a chamber for installing energy storage batteries 3 is opened in the outer wall of the main charging chamber 1, a fixed solar panel 4 for cooperating with the energy storage batteries 3 to charge is fixedly installed on the upper surface of the main charging chamber 1, a split-type flip solar panel 5 is movably assembled on the outer surface of the main charging chamber 1, an electronically controlled flip-type charging arm 6 is movably assembled on the inner top surface of the main charging chamber 1, a bottom loading and unloading port 7 is provided on the lower surface of the main charging chamber 1, and a split-type bottom bearing correction platform 8 for closing the bottom loading and unloading port 7 is provided at the lower end of the main charging chamber 1.

[0023] Working principle: During transportation, the unmanned optical cable maintenance equipment is loaded inside the main power replenishment chamber 1. After being transported to the designated location, the split-type bottom support and correction platform 8 descends, opening the bottom loading and unloading port 7. The unmanned optical cable maintenance equipment descends into the seawater along with the split-type bottom support and correction platform 8. Then, the split-type bottom support and correction platform 8 flips to both sides, and the unmanned optical cable maintenance equipment begins operation to inspect and maintain the optical cables on the seabed. At the same time, the fixed solar panel 4 and the split-type flip solar panel 5 on the upper surface of the main power replenishment chamber 1 work together with the energy storage battery 3 to replenish energy. When the unmanned optical cable maintenance equipment needs to replenish energy, it automatically rises to the bottom of the main power replenishment chamber 1. Then, the split-type bottom support and correction platform 8 lifts it from the bottom into the main power replenishment chamber 1. The conductive column on the top of the unmanned optical cable maintenance equipment is raised, and the electrically controlled flip-type energy replenishment arm 6 is used to squeeze the conductive column from both sides to make a connection. Then, the energy storage battery 3 quickly replenishes energy to the unmanned optical cable maintenance equipment, improving the energy replenishment efficiency.

[0024] To facilitate installation and fixation, the lower end of the outer side of the main energy replenishment tank 1 has an outwardly protruding bottom mounting seat 9, and the upper surface of the outer buoyancy platform 2 has an upper fixing mounting groove that matches the bottom mounting seat 9. The main energy replenishment tank 1 is bolted to the outer buoyancy platform 2 by inserting the bottom mounting seat into the upper fixing mounting groove.

[0025] The design of the detachable external buoyancy platform 2 allows for easy replacement and adjustment according to the load capacity.

[0026] To facilitate unfolding and folding, the split-type flip solar panel 5 includes a lateral assembly frame 51 fixed to the two side walls of the main energy replenishment chamber 1, a flip back plate 52 movably installed inside the lateral assembly frame 51, an inner guide rail 53 fixed to the inner side of the flip back plate 52, an inner electric control screw 54 movably installed inside the inner guide rail 53, an inner translation back plate 55 threaded onto the inner electric control screw 54 via two inner threaded blocks, a lateral adjustment support rod 56 for controlling the flip adjustment of the inner guide rail 53, and a solar auxiliary panel 57 fixed to the outer surface of the flip back plate 52 and the inner translation back plate 55.

[0027] The lateral adjustment strut 56 controls the inner guide rail 53 to flip by telescopic extension, while the inner electric control screw 54 controls the inner translation back plate 55 with internal thread blocks on both sides to perform translation adjustment by rotation. In this way, two-section solar auxiliary panels 57 can be formed on both sides of the main energy replenishment chamber 1, which can greatly increase the optical power generation area and improve the power generation efficiency.

[0028] To facilitate top-mounted tilting adjustment and energy replenishment, the electrically controlled tilting energy replenishment arm 6 includes two horizontally arranged top beams 61 fixedly installed on the top surface of the main energy replenishment chamber 1, a tilting adjustment arm 62 movably connected to the top beams 61, a horizontal energy replenishment arm 63 fixedly installed at the end of the tilting adjustment arm 62, a copper conductive sheet 64 elastically fitted on the pressing surface of the horizontal energy replenishment arm 63, and a top adjustment support rod 65 for controlling the tilting adjustment arm 62.

[0029] The top adjusting support rod 65 controls the tilting adjusting arm 62 to tilt along the top crossbeam 61 by telescopic movement, which then drives the copper conductive sheet 64 on the horizontal power supply arm 63 to press against the conductive column at the top of the unmanned optical cable maintenance equipment. The conductive column at the top of the unmanned optical cable maintenance equipment is controlled by an electric lifting method. A sealing cover plate is fixed on the top of the conductive column at the top of the unmanned optical cable maintenance equipment to improve the sealing of the top when the conductive column retracts.

[0030] The copper conductive sheet 64 is electrically connected to the power supply terminal of the energy storage battery 3 through the power transmission equipment.

[0031] To facilitate top lifting and tilting adjustments, the split-type bottom bearing correction platform 8 includes a top guide cylinder 81 fixed to the top surface of the main energy replenishment chamber 1, a longitudinally placed electric control screw 82 movably installed inside the top guide cylinder 81, an internally threaded lifting cylinder 83 threaded onto the outside of the longitudinally placed electric control screw 82, a tilting bearing plate 84 movably installed at the bottom of the internally threaded lifting cylinder 83, an electric control correction module 85 installed on the tilting bearing plate 84, and a bottom side adjusting support rod 86 for controlling the tilting of the tilting bearing plate 84.

[0032] The longitudinally positioned electric control screw 82 rotates electrically, thereby controlling the internal thread lifting cylinder 83 to rise and fall along the longitudinally positioned electric control screw 82.

[0033] Operating principle: When the unmanned optical cable maintenance equipment needs to be recharged due to insufficient power, the unmanned optical cable maintenance equipment rises to the bottom loading and unloading port 7 at the bottom of the main recharge chamber 1. Then, the bottom side adjusting support rod 86 retracts to control the flipping bearing plate 84 to flip inward and squeeze the bottom sides of the unmanned optical cable maintenance equipment for side compression correction until the flipping bearing plate 84 is horizontally set at the bottom of the unmanned optical cable maintenance equipment. Then, the longitudinally placed electric control screw 82 rotates to drive the internal thread lifting cylinder 83 and the flipping bearing plate 84 to lift the unmanned optical cable maintenance equipment into the main recharge chamber 1, and at the same time close the bottom loading and unloading port 7.

[0034] The upper cylinder of the bottom adjusting support rod 86 is movably mounted on the outer side of the internal thread lifting cylinder 83, while the extended end of the bottom adjusting support rod 86 is movably assembled with the surface of the flip bearing plate 84. The flip bearing plate 84 is flipped and adjusted along the bottom end of the internal thread lifting cylinder 83 by extending and retracting the bottom adjusting support rod 86.

[0035] To facilitate lateral assembly and electronic correction, the electronic correction module 85 includes a lateral assembly frame 851 mounted on the inner wall of the tilting bearing plate 84 and an electronic correction track 852 movably mounted inside the lateral assembly frame 851.

[0036] When the flip-up bearing plate 84 flips inward, the unmanned optical cable maintenance equipment is supported from bottom to top by the flip-up bearing plates 84 on both sides. Then, when the flip-up bearing plate 84 flips to the horizontal position, the electrically controlled correction tracks 852 on both sides are pressed against the sides of the unmanned optical cable maintenance equipment. Then, the electrically controlled correction tracks 852 can drive the unmanned optical cable maintenance equipment to move horizontally by running.

[0037] To facilitate horizontal adjustment and correction of the unmanned optical cable maintenance equipment from both sides after tilting and lifting, the electrically controlled correction track 852 includes an electrically driven wheel 8521, a support guide wheel 8522, and a correction track 8523 installed inside the lateral assembly frame 851.

[0038] The electric drive wheel 8521 drives the correction track 8523 to run, which in turn drives the support guide wheel 8522 to rotate and provide support. When the correction track 8523 rotates, it can drive the unmanned optical cable maintenance equipment to perform horizontal displacement.

[0039] In order to coordinate with the control of the main energy replenishment tank 1 to drive on the water surface, an embedded bottom guide shroud 10 is fixedly installed on the lower surface of the outer buoyancy platform 2. An electrically controlled guide impeller 11 is installed inside the embedded bottom guide shroud 10, and a lateral guide channel 12 is opened on the outer side of the outer buoyancy platform 2, which is connected to the discharge port of the embedded bottom guide shroud 10.

[0040] The electrically controlled guide impeller 11 draws water in from the bottom by rotating rapidly, and then discharges it through the side guide channel 12, thereby controlling the main energy replenishment tank 1 to travel on the water surface. Meanwhile, after the main energy replenishment chamber 1 is overturned by the large waves, its flipping and reset can be controlled by the high-speed rotation of two electrically controlled guide impellers 11 on one side.

[0041] In order to improve the surface dryness of the unmanned optical cable maintenance equipment and enhance the safety during the recharging process, a top-mounted dewatering fan 13 is fixedly installed on the top surface of the main recharging chamber 1 to remove water accumulated in the charging section of the unmanned optical cable maintenance equipment.

[0042] When the split-type bottom bearing correction platform 8 lifts the unmanned optical cable maintenance equipment into the main energy replenishment chamber 1, the top-mounted dewatering fan 13 starts to dry the upper surface of the unmanned optical cable maintenance equipment. Then, the charging head at the top of the unmanned optical cable maintenance equipment is lifted, and the electrically controlled flip-type energy replenishment arm 6 flips down from the upper sides on both sides to clamp the charging head on both sides and replenish the energy of the unmanned optical cable maintenance equipment.

[0043] To facilitate monitoring of the fiber optic cable maintenance equipment and drainage of internal water during lifting, an electrically controlled drain valve 14 and a pressure sensing module 15 are installed on the surface of the flip-over bearing plate 84.

[0044] The pressure sensing module 15 can detect the status of the unmanned optical cable maintenance equipment when the flipping support plate 84 is flipped and lifted. Then, based on the change in the mass of the unmanned optical cable maintenance equipment, the electrically controlled flipping energy replenishment arm 6 is activated. For example, in the initial stage, the squeezing pressure of the pressure sensing module 15 on the flipping support plate 84 will increase from small to large. Then, during the lifting process of the flipping support plate 84, the water accumulated on the unmanned optical cable maintenance equipment will be drained downwards, and the mass will decrease from large to a set value. When the flipping support plate 84 flips and closes the bottom loading and unloading port 7, the electrically controlled drain valve 14 is used to drain the water inside.

[0045] The pressure sensing module 15 can detect whether there are entanglements on the surface of the unmanned optical cable maintenance equipment by weighing it. If the entanglement is too large, it needs to be returned for maintenance.
