[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 and Figure 3 The self-energy replenishing equipment shown is used for optical cable maintenance equipment, including a main energy replenishing bin 1, a peripheral buoyancy aid platform 2 for assisting it to float on the water surface is fixedly installed at the lower edge of the main energy replenishing bin 1, a chamber for installing an energy storage battery 3 is opened inside the outer wall of the main energy replenishing bin 1, a fixed solar panel 4 for cooperating with the energy storage battery 3 for energy replenishment is fixedly installed on the upper surface of the main energy replenishing bin 1, a split flip solar panel 5 is movably installed on the outer surface of the main energy replenishing bin 1, an electric-controlled flip energy replenishing arm 6 is movably installed on the inner top surface of the main energy replenishing bin 1, a bottom loading and unloading port 7 is provided on the lower surface of the main energy replenishing bin 1, and a split bottom load-bearing correction platform 8 for closing the bottom loading and unloading port 7 is provided at the lower end of the main energy replenishing bin 1.

[0024] Working principle: During the transportation process, the unmanned optical cable maintenance equipment is loaded inside the main energy replenishing bin 1, and then transported to the designated position. The split bottom load-bearing correction platform 8 descends, and the bottom loading and unloading port 7 is opened. The unmanned optical cable maintenance equipment descends into the sea water along with the split bottom load-bearing correction platform 8, and then the split bottom load-bearing correction platform 8 flips to both sides. The unmanned optical cable maintenance equipment starts to run and inspects and maintains the optical cable on the seabed. At the same time, the fixed solar panels 4 and the split flip solar panels 5 on the upper surface of the main energy replenishing bin 1 cooperate with the energy storage battery 3 to replenish energy. When the unmanned optical cable maintenance equipment needs energy replenishment, it automatically rises to the bottom of the main energy replenishing bin 1, and then the split bottom load-bearing correction platform 8 lifts it from the bottom to the inside of the main energy replenishing bin 1. The conductive column on the top of the unmanned optical cable maintenance equipment is lifted, and the electrically controlled flip energy replenishing arm 6 is used to squeeze the conductive column from both sides to connect, and then the unmanned optical cable maintenance equipment is quickly replenished with energy through the energy storage battery 3, thereby improving the energy replenishment efficiency.

[0025] In order to cooperate with installation and fixation, the lower end of the outer side surface of the main energy replenishment tank 1 has a bottom side mounting seat 9 protruding outward, and the upper surface of the peripheral flotation platform 2 is provided with an upper fixed mounting groove that cooperates with the bottom side mounting seat 9. The main energy replenishment tank 1 is inserted into the upper fixed mounting groove through the bottom side mounting seat and is fixed to the peripheral flotation platform 2 with bolts.

[0026] The detachable outer flotation platform 2 is designed to be easily replaced and adjusted according to the load capacity.

[0027] In order to cooperate with the expansion and contraction, the split flip solar panel 5 includes a lateral assembly frame 51 fixed on the two side walls of the main energy replenishment chamber 1, a flip backboard 52 movably installed inside the lateral assembly frame 51, an inner guide rail 53 fixed on the inner side of the flip backboard 52, an inner electric control screw 54 movably installed inside the inner guide rail 53, an inner translation backboard 55 threadedly connected to the inner electric control screw 54 through internal thread blocks on both sides, a lateral adjustment strut 56 for controlling the flip adjustment of the inner guide rail 53, and a solar auxiliary panel 57 fixed on the outer surface of the flip backboard 52 and the inner translation backboard 55.

[0028] The lateral adjustment strut 56 controls the flipping of the inner guide rail 53 by telescoping, and 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 rotating, so that a two-stage solar auxiliary panel 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.

[0029] In order to cooperate with the overhead flip adjustment energy replenishment, the electrically controlled flip energy replenishment arm 6 includes two horizontally arranged overhead beams 61 fixedly installed on the top surface of the main energy replenishment chamber 1, a flip adjustment arm 62 movably connected to the overhead beam 61, a horizontal energy replenishment arm 63 fixedly installed at the end of the flip adjustment arm 62, a copper conductive sheet 64 elastically assembled on the extrusion surface of the horizontal energy replenishment arm 63 and a top adjustment support rod 65 for controlling the flip adjustment arm 62.

[0030] The top adjustment strut 65 controls the flip adjustment arm 62 to flip along the top beam 61 by telescoping, and then drives the copper conductive sheet 64 on the horizontal power supply arm 63 to squeeze 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 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.

[0031] The copper conductive sheet 64 is electrically connected to the power supply terminal of the energy storage battery 3 through a power transmission device.

[0032] In order to cooperate with the top lifting and flipping adjustment, the split bottom bearing correction platform 8 includes a top guide cylinder 81 fixed on the top surface of the main energy replenishment warehouse 1, a longitudinal electric control screw 82 movably installed inside the top guide cylinder 81, an internal thread lifting cylinder 83 threadedly sleeved on the outside of the longitudinal electric control screw 82, a flip bearing plate 84 movably installed at the bottom of the internal thread lifting cylinder 83, an electric control correction module 85 installed on the flip bearing plate 84 and a bottom side adjustment support rod 86 for controlling the flipping of the flip bearing plate 84.

[0033] The longitudinal electric control screw rod 82 is rotated by electric control, thereby controlling the internal thread lifting cylinder 83 to be raised and lowered along the longitudinal electric control screw rod 82 .

[0034] Operating principle: When the unmanned optical cable maintenance equipment has insufficient battery life and needs to be recharged, the unmanned optical cable maintenance equipment rises to the bottom loading and unloading port 7 at the bottom of the main recharging bin 1, and then the bottom side adjustment support rod 86 contracts to control the flip load plate 84 to flip inward and squeeze the bottom two sides of the unmanned optical cable maintenance equipment, and performs extrusion correction on both sides until the flip load plate 84 is horizontally set at the bottom of the unmanned optical cable maintenance equipment, and then the internal threaded lifting cylinder 83 and the flip load plate 84 are driven to lift by the longitudinal electric control screw 82, and the unmanned optical cable maintenance equipment is lifted to the inside of the main recharging bin 1, and the bottom loading and unloading port 7 is closed at the same time.

[0035] The upper end cylinder of the bottom side adjustment strut 86 is movably mounted on the outer side surface of the internal thread lifting cylinder 83, and the protruding end of the bottom side adjustment strut 86 is movably assembled with the surface of the flip supporting plate 84. The flip supporting plate 84 is controlled to be flipped and adjusted along the bottom end of the internal thread lifting cylinder 83 by extending and retracting the bottom side adjustment strut 86.

[0036] In order to cooperate with lateral assembly and electronically controlled correction, the electronically controlled correction module 85 includes a lateral assembly frame 851 installed on the inner wall of the flip carrier plate 84 and an electronically controlled correction track 852 movably installed inside the lateral assembly frame 851 .

[0037] When the flip supporting plate 84 flips inward, the unmanned optical cable maintenance equipment is supported from the bottom upward by the flip supporting plates 84 on both sides, and then the flip supporting plate 84 flips to a horizontal position. At this time, the electric-controlled correction tracks 852 on both sides are squeezed on both sides of the unmanned optical cable maintenance equipment, and then the electric-controlled correction tracks 852 can drive the unmanned optical cable maintenance equipment to move horizontally by operation.

[0038] In order to facilitate the horizontal adjustment and correction of the unmanned optical cable maintenance equipment from both sides after flipping and lifting, the electrically controlled correction track 852 includes an electric drive wheel 8521 installed inside the lateral assembly frame 851, a support guide wheel 8522 and a correction track 8523.

[0039] The electric drive wheel 8521 drives the correction track 8523 to run, thereby driving the support guide wheel 8522 to rotate and support. When the correction track 8523 rotates, it can drive the unmanned optical cable maintenance equipment to move horizontally.

[0040] In order to cooperate with the control of the main energy replenishment tank 1 driving on the water surface, an embedded bottom fairing 10 is fixedly installed on the lower surface of the peripheral buoyancy-aiding platform 2. An electric-controlled guide impeller 11 is installed inside the embedded bottom fairing 10. A lateral guide groove 12 connected to the discharge port of the embedded bottom fairing 10 is opened on the outside of the peripheral buoyancy-aiding platform 2.

[0041] The electrically controlled guide impeller 11 rotates rapidly to draw water in from the bottom, and then discharges it through the lateral guide groove 12, thereby controlling the main energy charging tank 1 to travel on the water surface; At the same time, after the main energy replenishment tank 1 is overturned by a big wave, its overturning and reset can be controlled by the high-speed rotation of the two electrically controlled guide impellers 11 on one side.

[0042] In order to improve the surface dryness of the unmanned optical cable maintenance equipment and enhance the safety during the energy charging process, a top-mounted dewatering fan 13 is fixedly installed on the top surface of the main energy charging chamber 1 to remove water accumulated in the charging section of the unmanned optical cable maintenance equipment.

[0043] When the split bottom load-bearing correction platform 8 lifts the unmanned optical cable maintenance equipment into the main energy charging compartment 1, the top-mounted dehumidification fan 13 is started to dry the upper surface of the unmanned optical cable maintenance equipment, and then the charging head on the upper end of the unmanned optical cable maintenance equipment is lifted, and then the electrically controlled flip-type energy charging arm 6 is flipped downward from the upper ends on both sides and clamped on both sides of the charging head to perform energy charging operations on the unmanned optical cable maintenance equipment.

[0044] In order to facilitate monitoring of the optical cable maintenance equipment and draining of the accumulated water inside when the flip support plate 84 is lifted, an electrically controlled drain valve 14 and a pressure sensing module 15 are installed on the surface of the flip support plate 84 .

[0045] The pressure sensing module 15 can be used to detect the status of the unmanned optical cable maintenance equipment when the flip supporting plate 84 is flipped and lifted, and then the electrically controlled flip energy replenishing arm 6 is started according to the mass change of the unmanned optical cable maintenance equipment. For example, in the initial stage, the squeezing force of the pressure sensing module 15 on the flip supporting plate 84 will increase from small to large, and then when the flip supporting plate 84 is lifted, the accumulated water on the unmanned optical cable maintenance equipment will be discharged downward, and the mass will decrease from large to a set value. When the flip supporting plate 84 flips and closes the bottom loading and unloading port 7, the electrically controlled drain valve 14 is used to drain the accumulated water inside.

[0046] The pressure sensing module 15 can detect whether there is any entanglement 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.

[0047] 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.
