Description

Technical Field

[0001] This invention relates to the field of waterborne photovoltaic technology, and more particularly to a waterborne robot. Background Technology

[0002] With the widespread application of aquatic robots (such as unmanned vessels, surface buoys, and marine exploration platforms) in fields such as marine environmental monitoring, emergency rescue, and patrol reconnaissance, their endurance and autonomous recharging needs are becoming increasingly prominent. Traditional methods mainly rely on returning to port for charging or battery replacement, which significantly increases operating costs. They also often use fixed or rigidly deployed solar panels, which occupy a lot of space, affect navigation stability, and waste space when not charging, making them difficult to integrate efficiently into small aquatic robots. Summary of the Invention

[0003] The present invention provides an aquatic robot to solve at least one of the problems mentioned in the background art.

[0004] The aquatic robot of this application includes a body, a power supply, and a flexible photovoltaic module. The body has a receiving cavity, the power supply is located inside the body, the flexible photovoltaic module is housed in the receiving cavity, the flexible photovoltaic module has an air cavity, and the flexible photovoltaic module can expand and unfold from inside the receiving cavity to outside the receiving cavity after the air cavity is inflated. The flexible photovoltaic module is electrically connected to the power supply.

[0005] In the aquatic robot of this application embodiment, the flexible photovoltaic module can be housed in the housing cavity of the body, which can prevent it from affecting the shape of the aquatic robot when not in use, thus improving the structural compactness of the aquatic robot. When the flexible photovoltaic module is needed, the air cavity of the flexible photovoltaic module is inflated to expand and unfold the flexible photovoltaic module, providing additional photovoltaic power to the power supply of the aquatic robot, effectively improving the charging efficiency of the aquatic robot and meeting the relevant usage requirements.

[0006] In some embodiments, the aquatic robot includes a tow rope, one end of which is connected to the flexible photovoltaic module and the other end to the body.

[0007] In the above embodiment, the traction rope connects the flexible photovoltaic module and the machine body, and limits the pop-out distance of the flexible photovoltaic module by physical limiting, ensuring that the flexible photovoltaic module is always within a controllable range and is easy to store later.

[0008] In some embodiments, the aquatic robot includes a guide wire connecting the flexible photovoltaic module and the body, the guide wire being arranged along the traction rope.

[0009] In the above embodiments, the wires are arranged along the traction rope, which can effectively prevent the wires from getting tangled or interfering with other components during the expansion of the flexible photovoltaic module, thus ensuring a reliable electrical connection for the flexible photovoltaic module.

[0010] In some embodiments, the water robot includes a protective sheath that covers at least a portion of the traction rope and the conductor.

[0011] In the above embodiments, the protective sleeve covers the surface of the traction rope and the wire, which can effectively prevent external objects from directly acting on the wire and help improve the service life of the wire and the traction rope.

[0012] In some embodiments, the flexible photovoltaic module includes a junction box disposed within the receiving cavity and electrically connected to the power source, wherein the wires are used to collect the electrical energy generated by the flexible photovoltaic module to the junction box.

[0013] In the above embodiments, the junction box is located inside the receiving cavity, which can effectively prevent the junction box from being directly affected by sea waves or other external objects, which is conducive to improving the working stability of the flexible photovoltaic module and further improving the space utilization of the receiving cavity.

[0014] In some embodiments, the flexible photovoltaic module forms a housing chamber after the air cavity expands and unfolds, the housing chamber having an upward opening, the housing chamber being used to carry objects.

[0015] In the above embodiments, after the flexible photovoltaic module expands and unfolds, it forms a accommodating compartment that can be used to support objects, effectively improving the functional integration of the flexible photovoltaic module.

[0016] In some embodiments, when the flexible photovoltaic module is in its expanded state, the side of the flexible photovoltaic module away from the fuselage has an opening that communicates with the housing compartment.

[0017] In the above embodiments, the opening formed by the flexible photovoltaic module can allow rescued personnel to smoothly enter the containment cabin in emergency rescue scenarios, ensuring the maritime emergency rescue function of the flexible photovoltaic module.

[0018] In some embodiments, the aquatic robot further includes a pop-out mechanism fixed within the receiving cavity for popping the flexible photovoltaic module out of the receiving cavity.

[0019] In the above embodiment, the flexible photovoltaic module is ejected from the receiving cavity by an ejection mechanism. The ejection mechanism ensures that the flexible photovoltaic module can be smoothly removed from the receiving cavity. The ejection mechanism is set inside the receiving cavity, which further improves the overall structural compactness.

[0020] In some embodiments, the ejection mechanism includes an air storage container disposed within the receiving cavity. The air storage container includes a valve head for sealing its air passage. After the valve head is opened, the air storage container inflates the air cavity and causes the flexible photovoltaic module to expand and eject.

[0021] In the above embodiments, the inflation and deflation of the flexible photovoltaic module are both achieved by the gas storage container, without the need for an additional mechanical deflation structure, and the overall action is smooth and fast.

[0022] In some embodiments, the aquatic robot further includes a ducted fan connected to and electrically connected to the fuselage, the ducted fan being used to propel the fuselage.

[0023] In the above embodiments, the water robot can navigate on the water surface and in the air by means of a ducted fan connected to its body, which improves the functional versatility of the water robot. The annular duct of the ducted fan can effectively prevent debris from getting tangled and bumping into it, thus improving the safety and stability of the water robot's navigation.

[0032] Please see Figures 1-5 , Figure 1 This is a structural schematic diagram of one state of the water robot 100 according to an embodiment of the present invention. Figure 2 This is a structural schematic diagram of another state of the aquatic robot 100 according to an embodiment of the present invention. Figure 3 This is a schematic diagram of the flexible photovoltaic module 30 according to an embodiment of the present invention when unfolded. Figure 4 This is a schematic diagram of the unfolded structure of the flexible photovoltaic module 30 according to an embodiment of the present invention. Figure 5 This is a partial structural schematic diagram of the aquatic robot 100 according to an embodiment of the present invention.

[0033] The aquatic robot 100 of this application includes a body 10, a power supply 20, and a flexible photovoltaic module 30. The body 10 is provided with a receiving cavity 11. The power supply 20 is disposed inside the body 10. The flexible photovoltaic module 30 is housed in the receiving cavity 11. The flexible photovoltaic module 30 is provided with an air cavity 31. The flexible photovoltaic module 30 can expand and unfold from inside the receiving cavity 11 to outside the receiving cavity 11 after the air cavity 31 is inflated. The flexible photovoltaic module 30 is electrically connected to the power supply 20.

[0034] In the underwater robot 100 of this application embodiment, the flexible photovoltaic module 30 can be housed in the receiving cavity 11 of the body 10, which can prevent it from affecting the shape of the underwater robot 100 when not in use, thus improving the structural compactness of the underwater robot 100. When the flexible photovoltaic module 30 is needed, the air cavity 31 of the flexible photovoltaic module 30 is inflated, causing the flexible photovoltaic module 30 to expand and unfold, providing additional photovoltaic energy to the power supply 20 of the underwater robot 100, effectively improving the charging efficiency of the underwater robot 100 and meeting relevant usage requirements.

[0035] Specifically, the water robot 100 is an unmanned platform that can perform autonomous navigation or controlled operation tasks on the water surface or in near-shore waters. Its body 10 serves as the main load-bearing structure and integrates a power supply 20 and a housing cavity 11. The power supply 20 provides power for the navigation and operation load of the water robot 100, and at the same time serves as the power receiving end of the flexible photovoltaic module 30 to realize energy storage and reuse.

[0036] The containment cavity 11 is a sealed chamber located inside the fuselage 10 and isolated from the external water body. The cavity's outline is adapted to the flexible photovoltaic module 30 in its folded state, allowing the flexible photovoltaic module 30 to be fully housed when the aquatic robot 100 is navigating or not performing solar charging operations. This maintains a smooth, continuous streamlined profile on the exterior of the fuselage 10, avoiding increased water resistance and navigation interference caused by protruding photovoltaic modules. It also provides physical protection for the flexible photovoltaic module 30 in its folded state, reducing the risk of damage from wave impacts and scratches from floating debris. The power supply 20 is a large-capacity energy storage unit integrated inside the fuselage 10. As the power source for the aquatic robot 100's power and control core, it stores the electrical energy converted from the flexible photovoltaic module 30 and provides stable power output to onboard equipment such as the propulsion system, control system, and communication module.

[0037] The water robot 100 also includes a hatch 90. The power supply 20 is located inside the body 10 of the water robot 100. The hatch 90 shields the power supply 20. When the hatch 90 is closed, the power supply 20 is isolated from the external environment, which prevents damage to the power supply 20 caused by sea waves, foreign objects, etc., and helps to maintain the stability of the operating environment of the power supply 20. When the hatch 90 is opened, the internal components such as the power supply 20 can be maintained, which is convenient for operators to inspect or replace.

[0038] The flexible photovoltaic module 30 is a foldable charging component made of flexible thin-film solar cells. Its substrate is a high-strength flexible material, which can be folded and unfolded multiple times without damaging the power generation performance. The flexible photovoltaic module 30 integrates an inflatable air cavity 31. The air cavity 31 is arranged along the force-bearing skeleton of the flexible photovoltaic module 30. After inflation, it can form a uniform rigid support, which not only provides the tension and shape retention force required for the flexible photovoltaic module 30 to unfold, but also allows it to leave the receiving cavity 11 with the pressure of inflation, pushing the flexible photovoltaic module 30 to pop out smoothly from the receiving cavity 11 and fully unfold to the outside of the body 10.

[0039] The unfolded flexible photovoltaic module 30 can receive sunlight with the maximum light-receiving area, efficiently converting solar energy into electrical energy, and then charging the power supply 20 inside the body 10 through the preset electrical connection line, realizing the autonomous energy supply of the water robot 100 in the static floating state without relying on external charging facilities, thus extending the endurance of the water robot 100.

[0040] The flexible photovoltaic module 30 can be popped out and deployed by inflating, which effectively simplifies the system structure and reduces the failure rate and maintenance cost. The flexible photovoltaic module 30 is stored in the housing cavity 11 when it is in storage, which improves the utilization rate of the internal space of the body 10. The flexible photovoltaic module 30 can be deployed on the water surface as needed, which can improve the photovoltaic energy replenishment efficiency of the water robot 100 and meet relevant requirements.

[0041] In addition, the inflated air cavity 31 and the flexible photovoltaic module 30 can together form an inflatable cushion structure with a certain buoyancy. When the water robot 100 encounters a malfunction or emergency, it can provide additional buoyancy support for the equipment, improve its survivability in harsh sea conditions, and have the dual functions of charging and safety assistance.

[0042] Please see Figure 3 and Figure 4 In some embodiments, the water robot 100 includes a tow rope 40, one end of which is connected to a flexible photovoltaic module 30 and the other end of which is connected to the body 10.

[0043] In the above embodiment, the traction rope 40 connects the flexible photovoltaic module 30 and the body 10, and limits the pop-out distance of the flexible photovoltaic module 30 by physical limiting, so as to ensure that the flexible photovoltaic module 30 is always within a controllable range and is convenient for subsequent storage.

[0044] Specifically, the traction rope 40 is a flexible high-strength rope. One end of the rope is fixedly connected to the edge or stress node of the inflated and deployed flexible photovoltaic module 30, and the other end is reliably connected to the preset traction point of the body 10. When the flexible photovoltaic module 30 is inflated in the air cavity 31 and pops out of the receiving cavity 11 and unfolds, the traction rope 40 can effectively limit its maximum unfolding distance, preventing the photovoltaic module from drifting excessively or detaching from the body 10 under the impact of waves and ocean currents, and avoiding the risk of cable pulling and equipment loss.

[0045] In addition, the traction rope 40 can transmit the traction force of the fuselage 10 on the flexible photovoltaic module 30, so that the flexible photovoltaic module 30 maintains a stable relative position with the fuselage 10 on the water surface, reduces the swaying and twisting caused by the water flow impact, and reduces fatigue damage to the flexible photovoltaic module 30 and electrical connection lines.

[0046] The length and strength of the tow rope 40 can be adapted to the sea conditions of the operating area. While ensuring the maximum unfolding area and optimal light-receiving efficiency of the flexible photovoltaic module 30, it maintains the overall navigation stability and controllability of the fuselage 10. It provides a reliable connection medium for emergency recovery of the flexible photovoltaic module 30. When storage is required, the flexible photovoltaic module 30 floating on the water surface can be pulled back to the vicinity of the fuselage 10 through the tow rope 40. The folding and storage are completed in conjunction with the deflation action, which improves the convenience and reliability of the system recovery operation.

[0047] Please see Figure 3 and Figure 4 In some embodiments, the water robot 100 includes a guide wire 50 connecting the flexible photovoltaic module 30 and the body 10, and the guide wire 50 is arranged along a traction rope 40.

[0048] In the above embodiment, the wire 50 is arranged along the traction rope 40, which can effectively prevent the wire 50 from getting tangled or interfering with other components during the expansion of the flexible photovoltaic module 30, and provide a guarantee for the reliable electrical connection of the flexible photovoltaic module 30.

[0049] Specifically, the conductor 50 is a power transmission line connecting the flexible photovoltaic module 30 and the power supply unit 20 of the fuselage 10. It is arranged along the direction of the traction rope 40 and can form an integrated structure with the traction rope 40 by binding, embedding or covering. When the flexible photovoltaic module 30 is inflated and unfolded, the conductor 50 unfolds synchronously with the traction rope 40. When the flexible photovoltaic module 30 is retracted and folded, it is also stored in the housing cavity 11 of the fuselage 10 or the corresponding wiring space along with the traction rope 40. There is no need to set up an additional independent cable storage mechanism, which avoids damage caused by the conductor 50 floating on the water surface, getting tangled or being pulled by the impact of waves, and also reduces the extra space occupied by the cable, improving the compactness and reliability of the overall structure.

[0050] Furthermore, the tow rope 40 provides physical protection for the conductor 50, buffering the impact of water flow and the external forces caused by the scraping of floating objects, reducing the wear, bending fatigue and short circuit risk of the conductor 50, ensuring the stability and continuity of the photovoltaic module's power supply to the power source 20 of the fuselage 10, simplifying the wiring layout, optimizing the system's space utilization, and ensuring that the conductor 50 always maintains reasonable tension and direction under the constraint of the tow rope 40, avoiding excessive pulling or loosening and knotting, thus improving the durability and operational stability of the entire charging system in complex marine environments.

[0051] Please see Figure 6 , Figure 6 This is a cross-sectional schematic diagram of the protective sleeve 60, the traction rope 40, and the guide wire 50 according to an embodiment of the present invention. In some embodiments, the water robot 100 includes a protective sleeve 60 that covers at least a portion of the traction rope 40 and the guide wire 50.

[0052] In the above embodiment, the protective sleeve 60 covers the surface of the traction rope 40 and the wire 50, which can effectively prevent external objects from directly acting on the wire 50, and is conducive to improving the service life of the wire 50 and the traction rope 40.

[0053] Specifically, the protective sleeve 60 is a flexible protective component that wraps around at least a portion of the traction rope 40 and the wire 50. It can be made of wear-resistant and seawater corrosion-resistant polymer materials. It is fixed to the outside of the traction rope 40 and the wire 50 by means of sleeve, heat shrinking or wrapping, integrating the two into a single structure. During the deployment, floating and retrieval of the flexible photovoltaic module 30, it can provide physical protection for the traction rope 40 and the wire 50 at the same time, avoiding wear and damage caused by wave erosion, scratching by floating objects, and entanglement by marine organisms. It can also effectively block seawater erosion and prevent the insulation layer of the wire 50 from aging, short circuit or the traction rope 40 from being corroded and broken.

[0054] The protective sleeve 60 can constrain the relative position of the towing rope 40 and the wire 50, preventing them from tangling and twisting under the impact of water flow, reducing the risk of storage failure and power transmission interruption caused by cable knots, and also reducing the overall structure's resistance in water, improving floating stability. Its integrated wrapping structure can accommodate the extension and bending movements of the towing rope 40 and the wire 50, and can maintain reliable protective performance during long-term offshore operations, further improving the durability and operational stability of the flexible photovoltaic module 30.

[0055] Please see Figure 2 and Figure 5 In some embodiments, the flexible photovoltaic module 30 includes a junction box 32, which is disposed in the receiving cavity 11 and electrically connected to the power supply 20. The wire 50 is used to collect the electrical energy generated by the flexible photovoltaic module 30 to the junction box 32.

[0056] In the above embodiment, the junction box 32 is located inside the receiving cavity 11, which can effectively prevent the junction box 32 from being directly affected by sea waves or other external objects, which is conducive to improving the working stability of the flexible photovoltaic module 30 and further improving the space utilization of the receiving cavity 11.

[0057] Specifically, the junction box 32 is a waterproof busbar component installed inside the housing cavity 11 of the body 10. It can be made of high-strength engineering plastic or metal material that is resistant to seawater corrosion, and waterproof and dustproof performance can be achieved through potting, sealing ring or ultrasonic welding process. The junction box 32 integrates a busbar, anti-reverse charging diode, overcurrent protection element and voltage stabilizing circuit module. It is rigidly connected to the internal structure of the housing cavity 11 through a preset fixed bracket, and is always within the protective space of the housing cavity 11, and does not move with the unfolding and retraction of the flexible photovoltaic module 30.

[0058] The junction box 32 is stably connected to the power supply unit 20 inside the body 10. As a transfer node for the flexible photovoltaic module 30 to transmit power to the power supply 20, it is responsible for receiving and organizing the power generated by the flexible photovoltaic module 30. It also prevents the current from the power supply 20 from flowing back to the photovoltaic module through anti-reverse charging components. At the same time, it filters and limits the power through overcurrent protection and voltage regulation modules to ensure the stability and safety of charging the power supply 20.

[0059] One end of the wire 50 is fixedly connected to the output end of the power generation unit of the flexible photovoltaic module 30, and the other end passes through the sealed wire hole on the wall of the receiving cavity 11 and enters the receiving cavity 11, where it is reliably connected to the busbar in the junction box 32. The entire wire 50 is arranged along the traction rope 40 and wrapped by the protective sleeve 60. It stretches out synchronously with the inflation and unfolding action of the flexible photovoltaic module 30, and is also stored together with the traction rope 40 when it is retracted and folded.

[0060] The junction box 32 is located inside the housing cavity 11, which keeps it within the protective space of the body 10, avoiding direct exposure to the harsh environment of seawater, salt spray, wave impact, and marine organisms. This reduces the risk of corrosion, water ingress, or mechanical damage to the junction box 32 and electrical connection parts. The connection end of the wire 50 to the junction box 32 is fixed inside the housing cavity 11, which reduces the pulling and twisting damage to the connection parts of the junction box 32 caused by the wire 50 during the repeated unfolding and retraction of the flexible photovoltaic module 30. This prevents the connection parts from becoming loose, having poor contact, or experiencing open circuit failures, further ensuring the reliability of the power transmission link and providing continuous and safe energy supply for the aquatic robot 100.

[0061] Please see Figure 4 In some embodiments, the flexible photovoltaic module 30 forms a housing 33 after the air cavity 31 expands and unfolds. The housing 33 has an upward-facing opening 331 and is used to carry objects.

[0062] In the above embodiments, after the flexible photovoltaic module 30 expands and unfolds, it forms a accommodating chamber 33 that can be used to carry objects, effectively improving the functional integration of the flexible photovoltaic module 30.

[0063] Specifically, after the air cavity 31 is filled with gas, it gradually expands, fully unfolding and shaping the folded flexible photovoltaic module 30. The module's own material and the inflated cavity work together to enclose the housing 33, which has an upward-facing opening 331 at the top. The inflated air cavity 31 acts as a frame to maintain the overall shape of the housing 33 and provides sufficient buoyancy. Combined with the material properties of the flexible photovoltaic module 30, the housing 33 has good buoyancy and structural toughness, and can withstand the impact of waves on the water surface without easily deforming or capsizing.

[0064] The containment chamber 33 can be used to carry various items such as testing instruments, emergency supplies, and small tools required for water operations, expanding the equipment carrying capacity. It can also serve as an emergency rescue carrier, allowing people in distress to enter the chamber for temporary shelter and board, using the buoyancy provided by the air chamber 31 to float on the water surface, thus improving water survival safety. The upward-facing open space 331 provides ample space, facilitating quick entry for people in distress and making it easy to deploy and retrieve rescue equipment and emergency supplies. The surrounding edges of the chamber provide effective protection, preventing people from accidentally slipping into the water due to currents.

[0065] Once the rescue or operational task is completed, the gas inside the air chamber 31 is released, and the containment chamber 33 loses its support and retracts and bends accordingly, folding together with the flexible photovoltaic module 30 and smoothly stored inside the containment chamber 11 of the body 10. No separate storage structure is required, and no additional external space is occupied. The overall structure remains simple and neat. While retaining the original photovoltaic power generation function, it expands to include practical material carrying and water rescue functions, realizing multi-functional reuse of the structure and improving the emergency support capability of the water robot 100 when operating in complex waters.

[0066] Please see Figure 4 In some embodiments, when the flexible photovoltaic module 30 is in an expanded state, the side of the flexible photovoltaic module 30 away from the fuselage 10 is provided with an opening 34 that communicates with the housing 33.

[0067] In the above embodiments, the opening 34 formed by the flexible photovoltaic module 30 can allow rescued personnel to smoothly enter the containment cabin 33 in emergency rescue scenarios, ensuring the maritime emergency rescue function of the flexible photovoltaic module 30.

[0068] Specifically, after the flexible photovoltaic module 30 expands and unfolds through the air cavity 31, it maintains a stable three-dimensional shape. A lateral opening 34 is provided on the side of the module away from the fuselage 10, and the opening 34 is interconnected with the internal accommodating compartment 33. The opening 34 and the surrounding structure are integrated with the photovoltaic module and the air cavity 31, and the material has excellent toughness, making it less prone to deformation and damage when facing the impact of water waves. The opening 34 is positioned close to the water surface, allowing personnel who fall into the water to directly enter the accommodating compartment 33 from the water, greatly reducing the difficulty of boarding and reducing physical exertion.

[0069] The perimeter of opening 34 prevents water from flowing into the cabin and restricts personnel movement to prevent accidental falls into the water. The side opening 34, combined with the top opening 331 of the accommodating compartment 33, forms two passageways, allowing for normal personnel entry and exit as well as the transfer of rescue equipment and operational supplies, adaptable to various usage scenarios. After the operation or rescue is completed, the air chamber 31 is emptied, and the side opening 34 folds and retracts synchronously with the flexible photovoltaic module 30. The flexible photovoltaic module 30 is then stored inside the housing cavity 11 of the fuselage 10, maintaining a neat overall shape and a simple and smooth storage process.

[0070] Please see Figures 3-5 In some embodiments, the aquatic robot 100 also includes a pop-out mechanism 70, which is fixed inside the receiving cavity 11 and is used to pop out the flexible photovoltaic module 30 from the receiving cavity 11.

[0071] In the above embodiment, the flexible photovoltaic module 30 is ejected from the receiving cavity 11 by the ejection mechanism 70. The ejection mechanism 70 ensures that the flexible photovoltaic module 30 can be smoothly removed from the receiving cavity 11. The ejection mechanism 70 is set inside the receiving cavity 11, which further improves the overall structural compactness.

[0072] Specifically, the pop-out mechanism 70 is fixedly assembled inside the receiving cavity 11 of the body 10, and its installation position remains constant. The pop-out mechanism 70 is used to drive the flexible photovoltaic module 30 in the folded state. It can output a stable pushing force to overcome the frictional resistance between the module and the inner wall of the cavity and the restraint of the limiting structure, and smoothly push the flexible photovoltaic module 30 out of the receiving cavity 11. When the flexible photovoltaic module 30 is stored and folded, the pop-out mechanism 70 will not interfere with the placement or folding of the flexible photovoltaic module 30, allowing the flexible photovoltaic module 30 to be completely stored inside the cavity.

[0073] When the operation is completed and retrieval is required, the flexible photovoltaic module 30 deflates, retracts, and folds back, accurately returning to the containment cavity 11 and parking in the corresponding working area of ​​the ejection mechanism 70. The entire structure can be repeatedly operated in cycles. The ejection mechanism 70 is integrated inside the fuselage 10, with no protruding external parts, thus not increasing the equipment's navigation drag. It is also protected by the containment cavity 11, effectively resisting the intrusion of seawater and debris. It operates stably during long-term use, further improving the smoothness of the deployment of the flexible photovoltaic module 30 under long-term use conditions and the overall operational reliability of the equipment.

[0074] Please see Figure 5 In some embodiments, the ejection mechanism 70 includes an air storage container 71 disposed in the receiving cavity 11. The air storage container 71 includes a valve head 711 for blocking its air passage. After the valve head 711 is opened, the air storage container 71 inflates the air cavity 31 and causes the flexible photovoltaic module 30 to expand and then eject.

[0075] In the above embodiments, the inflation and deflation of the flexible photovoltaic module 30 are both achieved by the gas storage container 71, without the need for an additional mechanical deflation structure, and the overall action is smooth and fast.

[0076] Specifically, the core component of the ejection mechanism 70 is the gas storage container 71. The gas storage container 71 is fixedly installed inside the receiving cavity 11 of the fuselage 10. The overall structure is sealed and adapted to the cavity space, allowing for long-term storage of compressed gas. The gas storage container 71 is equipped with a dedicated valve head 711, which is normally kept closed, completely sealing the gas passage of the gas storage container 71, preventing internal gas leakage, ensuring stable internal gas pressure, and reserving sufficient power for subsequent operations.

[0077] When the device needs to unfold the flexible photovoltaic module 30, the control system triggers the valve head 711 to open. The compressed gas stored inside the gas storage container 71 is instantly injected into the air cavity 31 of the flexible photovoltaic module 30 through the connected air passage. The air cavity 31 expands rapidly under the pressure of the gas. On the one hand, it generates a continuous expansion thrust, which overcomes the limiting resistance and structural friction of the receiving cavity 11 and pushes the folded flexible photovoltaic module 30 out of the receiving cavity 11 smoothly. On the other hand, the continuous inflation allows the flexible photovoltaic module 30 to fully unfold and take shape, stably forming a housing chamber 33 structure with a side opening 34 and a top opening 331.

[0078] The gas storage container 71 integrates the inflation and deployment of the flexible photovoltaic module 30 without the need for additional mechanical structures such as motors and transmission push rods. It uses air pressure to drive the deployment and deployment operations. The structure is simple and the response speed is fast. The entire process is integrated into the housing cavity 11. There is no exposed structure when it is stored, which will not increase the navigation drag of the fuselage 10. At the same time, the sealed gas storage structure is resistant to seawater corrosion and wind and wave interference, which greatly improves the operational stability and reliability in complex water environments.

[0079] Please see Figures 1-4 In some embodiments, the water robot 100 also includes a ducted fan 80, which is connected to and electrically connected to the body 10, and is used to propel the body 10.

[0080] In the above embodiments, the water robot 100 can navigate on the water surface and in the air by means of the ducted fan 80 connected to its body 10, thereby improving the functional versatility of the water robot 100. The annular duct of the ducted fan 80 can effectively prevent debris from getting tangled and bumping into it, thereby improving the safety and stability of the water robot 100's navigation.

[0081] Specifically, the ducted fan 80 mounted on the aquatic robot 100 is securely installed at the corresponding mounting position on the body 10. It is electrically connected to the internal power supply 20 and control system of the body 10 via onboard circuitry, allowing for unified power supply and intelligent control by the body 10 system. The ducted fan 80 integrates a ring-shaped duct protective structure, with its impeller completely housed within the duct, preventing direct exposure during operation. This effectively avoids the risks of collision and entanglement from floating debris, weeds, and waves, making it suitable for complex aquatic operating environments.

[0082] When the water robot 100 needs to move and navigate, the control system of the fuselage 10 outputs an electrical signal to drive the ducted fan 80 to operate. The high-speed rotating impeller continuously rotates to generate a continuous reverse thrust, thereby driving the fuselage 10 to move smoothly on the water surface, realizing the equipment's autonomous navigation, position fine adjustment, fixed-point hovering, and course adjustment.

[0083] For example, in an embodiment of this application, the shaft of the ducted fan 80 rotates around its axis to change the direction of the force exerted by the ducted fan 80. For instance, the ducted fan 80 can rotate around its axis to a direction perpendicular to the horizontal plane. In this case, the direction of the force exerted by the ducted fan 80 is perpendicular to the horizontal plane. When the magnitude of the force is greater than or less than the overall weight of the water robot 100, the water robot 100 achieves vertical upward or downward movement. Furthermore, different actions of the water robot 100 can be achieved by controlling the direction and magnitude of the force exerted by each ducted fan 80 to meet relevant usage scenarios.

[0084] The ducted fan 80 is continuously powered by the power supply 20 of the body 10, which is compatible with the power supply system of the whole machine. The power output is stable and uniform, with low navigation noise, small water disturbance and strong driving stability, effectively ensuring the maneuverability of the water robot 100 and meeting the mobile needs of multiple scenarios such as water patrol, emergency rescue and material delivery.
