Description

Technical Field

[0001] This utility model relates to the field of ship technology, specifically to an anti-submersion patrol boat. Background Technology

[0002] Patrol boats play a crucial role in the security system of coastal, inland, and border waters. As small vessels capable of performing multiple important tasks such as patrolling, law enforcement, and search and rescue, patrol boats, with their flexibility and maneuverability, can quickly respond to various emergencies in complex and ever-changing aquatic environments, effectively maintaining the safety and order of the waters. They are indispensable equipment for ensuring the normal conduct of maritime activities, combating illegal and criminal activities, and carrying out emergency rescue operations; their importance is self-evident.

[0003] From an equipment configuration perspective, patrol boats are typically equipped with small-caliber naval guns, machine guns, and other weapon systems to meet the needs of responding to potential threats and implementing necessary force interventions in different law enforcement scenarios. They are also equipped with various advanced rescue equipment, such as lifebuoys, stretchers, and first-aid supplies, to ensure timely and effective rescue of those in distress during search and rescue missions, thereby increasing their chances of survival. The coordinated operation of these equipment systems enables patrol boats to fulfill their duties comprehensively and at multiple levels.

[0004] However, patrol boats face challenges in power supply during operation. Due to the need for long-duration, high-intensity missions, their power demand is substantial, and a stable power supply is fundamental to ensuring the normal operation of all equipment on board and the smooth execution of missions. To meet this need, some patrol boats currently utilize photovoltaic panels, converting solar energy—a clean and renewable energy source—into electricity. By converting solar energy into electrical energy and storing it for backup, a certain amount of power support is provided for the continuous and stable operation of patrol boats, alleviating power supply pressure to some extent, and also aligning with the development concept of energy conservation and environmental protection.

[0005] However, existing photovoltaic (PV) panel applications have significant drawbacks. Currently, most PV panels are installed directly and exposed on the exterior of patrol boats, lacking effective storage and protection mechanisms. In harsh environments such as rainy weather, the PV panels cannot be stored away and remain continuously exposed to rainwater. Rainwater not only directly erodes the surface of the PV panels, damaging their coating and affecting light absorption and conversion efficiency, but impurities and acidic substances in the rainwater can also corrode the internal circuitry and electronic components, damaging their electrical performance. Prolonged exposure to such harsh environments significantly shortens the lifespan of the PV panels and gradually degrades their performance, ultimately affecting the stability and reliability of the entire solar power supply system. This prevents the PV panels from providing continuous and sufficient power support, posing a potential risk to their normal operation. Utility Model Content

[0006] The purpose of this utility model is to provide an anti-submersion patrol boat to solve at least one of the above-mentioned technical problems. It can effectively solve the problems of photovoltaic panel storage and protection, and has important practical significance for improving the power supply stability of patrol boats and ensuring the smooth execution of their various tasks.

[0007] This utility model achieves the above objectives through the following technical solutions: An anti-submersion patrol boat includes a patrol boat body, characterized in that the patrol boat further includes: a bilge keel disposed on the bilge of the patrol boat body, and a retractable photovoltaic panel assembly disposed on the top of the patrol boat body; The photovoltaic panel assembly includes, in a rotatable connection, a baffle, photovoltaic panel one, photovoltaic panel two, and photovoltaic panel three; The baffle is located at the upper end of the patrol boat body, and the photovoltaic panel one, the photovoltaic panel two, and the photovoltaic panel three are all located in the shielding cavity formed below the top surface of the baffle when they are in the stored state. The photovoltaic panel assembly further includes: a support column; the support column is connected to the top lower side of the baffle; Multiple limiting rings are provided on the side wall of the support column; the outer edge of the first limiting ring is connected to the photovoltaic panel one, and the outer edge of the second limiting ring is connected to the photovoltaic panel two. The top of photovoltaic panel three is slidably connected to the bottom of photovoltaic panel two; the top of photovoltaic panel two is slidably connected to the bottom of photovoltaic panel one; Pulling the photovoltaic panel three allows it to slide outwards in stages, unfolding the photovoltaic panel three, the photovoltaic panel two, and the photovoltaic panel one in sequence, so that the three photovoltaic panels are removed from the bottom shielding area of ​​the baffle.

[0008] Furthermore, the top of the photovoltaic panel one, the photovoltaic panel two, and the photovoltaic panel three are all provided with protruding rods; The bottom of the baffle, the first photovoltaic panel, and the second photovoltaic panel are all provided with sliding grooves; The sliding connection between the protruding rod and the sliding groove enables rotational connections between the baffle, photovoltaic panel one, photovoltaic panel two, and photovoltaic panel three in pairs.

[0009] Furthermore, the groove has an arc-shaped structure.

[0010] Furthermore, the arc center of the groove is located on the same vertical line as the rotation center point of photovoltaic panel one, photovoltaic panel two, and photovoltaic panel three.

[0011] Furthermore, the photovoltaic panel one, the photovoltaic panel two, and the photovoltaic panel three are distributed sequentially from top to bottom; The rotation center points of photovoltaic panel one, photovoltaic panel two, and photovoltaic panel three are located on the same vertical line.

[0012] Furthermore, there is a gap between the support column and the photovoltaic panel.

[0013] Furthermore, the photovoltaic panel assembly also includes: a mounting base; The longitudinal section of the baffle is inverted L-shaped, and the side of the baffle is connected to the side of the mounting base; The mounting base is equipped with a servo motor, the output end of which is connected to a rotating shaft, and the photovoltaic panel is located on the upper end of the rotating shaft.

[0014] Furthermore, the servo motor rotates clockwise or counterclockwise according to the control signal from the remote controller or the onboard controller.

[0015] Furthermore, photovoltaic panel one, photovoltaic panel two, and photovoltaic panel three all have a fan-shaped structure.

[0016] The beneficial effects of this utility model are as follows: This utility model's patrol boat features a highly efficient photovoltaic panel deployment and retraction function. A servo motor, driven by a remote control or onboard controller, rotates photovoltaic panel three. Then, a protruding rod precisely slides within an arc-shaped groove, sequentially rotating photovoltaic panel two and photovoltaic panel one, achieving the step-by-step deployment and retraction of the three photovoltaic panels. In the deployed state, the fan-shaped photovoltaic panels one, two, and three can be seamlessly joined to form a near-circular light-receiving surface, maximizing solar radiation capture per unit area and significantly improving power supply efficiency. In the retracted state, the fan-shaped outlines of each photovoltaic panel overlap, with consistent outer diameters, allowing them to be seamlessly embedded into the shading cavity beneath the top surface of the inverted L-shaped baffle. This not only effectively reduces radial dimensions and wind resistance, lowering the patrol boat's drag during navigation, but also provides reliable shading protection for the photovoltaic panels, reducing damage from external factors and extending their lifespan. This has significant practical implications for improving the stability of the patrol boat's power supply and ensuring the smooth execution of its various missions.

[0017] This invention, by installing bilge keels on the bilge section, effectively disturbs the flow field around the hull when the vessel rolls, generating additional damping. By increasing roll damping, the amplitude of the roll is significantly reduced, thereby achieving roll reduction and greatly enhancing the stability of the patrol boat in complex sea conditions. This effectively prevents capsizing, ensures the safety of the patrol boat's navigation, and enables it to perform various tasks more smoothly. Attached Figure Description

[0020] The present invention will now be discussed with reference to exemplary embodiments. It should be understood that the described embodiments are merely intended to enable those skilled in the art to better understand and thus implement the present invention, and are not intended to imply any limitation on the scope of the present invention.

[0021] As used herein, the term "comprising" and its variations are to be interpreted as open-ended terms meaning "including but not limited to". The term "based on" is to be interpreted as "at least partially based on". The terms "one embodiment" and "an embodiment" are to be interpreted as "at least one embodiment".

[0022] Example 1 Figure 1 This is a schematic diagram of the main structure of an anti-subversion patrol boat according to one embodiment of the present invention; Figure 2 This is a schematic diagram of a photovoltaic panel assembly in its unfolded state according to one embodiment of the present invention. Figure 1-2 As shown, according to one embodiment of the present invention, an anti-submersion patrol boat includes a patrol boat body 1, a bilge keel 2 disposed on the bilge of the patrol boat body 1, and a retractable photovoltaic panel assembly disposed on the top of the patrol boat body 1. The photovoltaic panel assembly includes the following components that are rotatably connected: baffle 3, photovoltaic panel one 7, photovoltaic panel two 8, and photovoltaic panel three 9; The baffle 3 is located at the upper end of the patrol boat body 1. Photovoltaic panel 7, photovoltaic panel 8 and photovoltaic panel 9 are all located in the shielding cavity formed below the top surface of the baffle 3 when they are in the stored state.

[0023] In this embodiment, an anti-capsulation patrol boat is provided: bilge keels 2 are symmetrically arranged on the bilge of the patrol boat body 1. The bilge keels 2 extend along the length of the boat and have a streamlined wing-like cross-section. When the boat rolls due to wind and waves, the bilge keels 2 disturb the flow field around the hull, inducing additional eddies and increasing the rolling damping moment, thereby suppressing the roll angle amplitude and period, improving stability, and reducing the risk of capsizing. A retractable photovoltaic panel assembly is installed on the top of the patrol boat body 1. The photovoltaic panel assembly includes a baffle 3 and photovoltaic panels 7, 8, and 9 stacked sequentially. Each photovoltaic panel and the baffle 3 rotate coaxially and can be deployed or retracted in stages. In the retracted state, the three photovoltaic panels are completely retracted into the shielding cavity formed below the top surface of the baffle 3. The baffle 3 simultaneously serves as a physical barrier and a rainproof layer, blocking external impacts and moisture intrusion, and extending the lifespan of the photovoltaic panels. When unfolded, photovoltaic panel 9 is manually or electrically rotated, which in turn pulls photovoltaic panel 8 and photovoltaic panel 7 outward in sequence. The three photovoltaic panels are laid out in a stepped manner on the same vertical rotation center, which increases the light-receiving area and does not block each other.

[0024] This invention features symmetrically arranged bilge keels extending along the length of the patrol boat and with a streamlined, wing-like cross-section. These keels suppress the amplitude and period of the boat's roll angle, improving stability and reducing the risk of capsizing. The retractable photovoltaic panel assembly of this invention can be protected from external impacts and moisture intrusion by baffles when stored, extending its lifespan. When deployed, the three photovoltaic panels are arranged in a stepped pattern, increasing the light-receiving area without obstructing each other.

[0025] Figure 3 This is a cross-sectional structural diagram of a photovoltaic panel module according to one embodiment of the present invention. Figure 3 As shown, according to one embodiment of the present invention, the photovoltaic panel assembly further includes: a support column 5; the support column 5 is connected to the lower top side of the baffle 3; Multiple limiting rings 6 are provided on the side wall of the support column 5; the outer edge of the first limiting ring 6 is connected to a photovoltaic panel 7, and the outer edge of the second limiting ring 6 is connected to a photovoltaic panel 8. The top of photovoltaic panel 39 is slidably connected to the bottom of photovoltaic panel 28; the top of photovoltaic panel 28 is slidably connected to the bottom of photovoltaic panel 17. Pulling photovoltaic panel 39 allows it to slide outwards in stages, unfolding photovoltaic panel 39, photovoltaic panel 28, and photovoltaic panel 17 in sequence, so that the three photovoltaic panels are removed from the bottom shaded area of ​​baffle 3.

[0026] In this embodiment, a support column 5 is added to the photovoltaic panel assembly. The upper end of the column is fixed to the lower side of the top of the baffle 3. Two limiting rings 6 are set from top to bottom on the outer wall of the column, which respectively rotate to support photovoltaic panel 7 and photovoltaic panel 8. The top of photovoltaic panel 9 and the bottom of photovoltaic panel 8, and the top of photovoltaic panel 8 and the bottom of photovoltaic panel 7 are connected by a sliding-rotation connection. When photovoltaic panel 9 is pulled manually or electrically, photovoltaic panel 8 and photovoltaic panel 7 are pulled outward step by step around the same vertical rotation center. The three fan-shaped panels are staggered in a stepped manner and are separated from the bottom shading area of ​​the baffle 3 to maximize the light-receiving area. When retracting, photovoltaic panel 9 is pushed in the opposite direction. The photovoltaic panels are stacked sequentially under the limiting of the baffle and re-embedded into the shading cavity below the baffle 3, completing the photovoltaic panel retraction and retraction action without tools, with low resistance and high reliability.

[0027] This utility model, through the design of support columns and limiting rings and a sliding-rotating connection structure, enables photovoltaic panels to be manually or electrically unfolded step by step in a staggered manner to maximize the light-receiving area. When retracted, they can be sequentially stacked and embedded into the shading cavity, completing the tool-free, low-resistance, and highly reliable unfolding and retraction operation.

[0028] Figure 4 This is a schematic diagram of the protruding rod structure according to one embodiment of the present invention; Figure 5 This is a schematic diagram of a groove structure according to one embodiment of the present invention. Figure 4-5 As shown, according to one embodiment of the present invention, the top of photovoltaic panel 7, photovoltaic panel 8 and photovoltaic panel 9 are all provided with protruding rods 10. The bottom of the baffle 3, photovoltaic panel 7 and photovoltaic panel 8 are all provided with sliding grooves 11; The sliding connection between the protruding rod 10 and the sliding groove 11 enables the rotational connection between each pair of the baffle 3, photovoltaic panel 7, photovoltaic panel 8, and photovoltaic panel 9.

[0029] Preferably, the groove 11 has an arc-shaped structure.

[0030] Preferably, the arc center of the slide groove 11 is located on the same vertical line as the rotation center point of photovoltaic panel 7, photovoltaic panel 8, and photovoltaic panel 9.

[0031] In this embodiment, a protruding rod 10 is provided on the outer edge of the top surface of photovoltaic panel 7, photovoltaic panel 8, and photovoltaic panel 9, and concentric arc-shaped grooves 11 are opened on the bottom surface of baffle 3, photovoltaic panel 7, and photovoltaic panel 8 respectively. The protruding rod 10 is embedded in the groove 11 to form a sliding-rotating pair. The arc center of the groove 11 coincides with the common vertical rotation center of the three photovoltaic panels, ensuring that when the protruding rod 10 moves in the groove, each photovoltaic panel unfolds or retracts in sequence around the same axis. When unfolding, the lower-level photovoltaic panel protrusion 10 slides along the upper-level slide groove 11 from the proximal end to the distal end, gradually pushing photovoltaic panel 8 and photovoltaic panel 7 to rotate outward until the three fan-shaped photovoltaic panels are staggered in a stepped manner to maximize the light-receiving area; when retracting, it is pushed in the opposite direction, and the protrusion 10 is gradually retracted under the limit of the stop block at the end of the slide groove 11, so that each photovoltaic panel is stacked in sequence and enters the bottom shielding cavity of the baffle 3 as a whole, realizing the photovoltaic panel unfolding and retracting movement without additional locking, low friction and high synchronization.

[0032] This invention utilizes a sliding-rotation connection design between a protruding rod and a concentric arc-shaped groove to allow three photovoltaic panels to unfold sequentially around the same axis in a stepped, staggered manner to maximize the light-receiving area. During retrieval, they can be stacked sequentially into the shielding cavity, achieving a retraction and unfolding movement with no additional locking, low friction, and high synchronization.

[0033] According to one embodiment of the present invention, photovoltaic panel 7, photovoltaic panel 8, and photovoltaic panel 9 are distributed from top to bottom; The rotation center points of photovoltaic panel 7, photovoltaic panel 8, and photovoltaic panel 9 are located on the same vertical line; There is a gap between support column 5 and photovoltaic panel 9.

[0034] In this embodiment, photovoltaic panels 7, 8, and 9 are arranged sequentially from top to bottom along the same vertical axis. The rotation centers of the three fan-shaped photovoltaic panels coincide with the center line of the support column 5, forming a coaxial stacked structure. When unfolded, the lower-level photovoltaic panels drive the upper-level photovoltaic panels to rotate around the same axis step by step through the convex rod-sliding groove pair. The panels are staggered in a stepped manner in the horizontal plane to avoid mutual shading and maximize the light-receiving area. When retracted, the panels are pushed in the opposite direction to stack sequentially along the same axis and are embedded into the bottom shading cavity of the baffle 3 for compact storage. The coaxial design simplifies the drive mechanism, reduces space occupation, and ensures synchronous and smooth unfolding / retraction actions, making it suitable for patrol boat applications where the top space of the hull is limited.

[0035] This utility model adopts a coaxial stacked structure of three photovoltaic panels. When unfolded, they are laid out in a stepped staggered manner to avoid shading and maximize the light-receiving area. When folded up, they are stacked sequentially and embedded into the shading cavity to achieve compact storage. The coaxial design simplifies the drive mechanism, reduces space occupation, and ensures synchronous and smooth operation.

[0036] Figure 6This is a bottom view schematic diagram of a photovoltaic panel assembly according to one embodiment of the present invention. Figure 6 As shown, according to one embodiment of the present invention, the photovoltaic panel module further includes: a mounting base 4; The longitudinal section of the baffle 3 is inverted L-shaped, and the side of the baffle 3 is connected to the side of the mounting base 4; The mounting base 4 is equipped with a servo motor 12. The output end of the servo motor 12 is connected to a rotating shaft 13. The photovoltaic panel 9 is located on the upper end of the rotating shaft 13.

[0037] Preferably, the servo motor 12 rotates clockwise or counterclockwise according to the control signal from the remote controller or the onboard controller.

[0038] In this embodiment, a mounting base 4 is added to the photovoltaic panel assembly: the longitudinal section of the baffle 3 is inverted L-shaped, and its vertical outer side is fastened to the side of the mounting base 4; the mounting base 4 is embedded with a servo motor 12, and the output end of the servo motor 12 extends upward through a rotating shaft 13 to below the horizontal section of the baffle 3, with the top of the rotating shaft 13 fixedly connected to the photovoltaic panel 9. The servo motor 12 receives forward / reverse signals from the remote controller or the ship's controller, driving the rotating shaft 13 to rotate the photovoltaic panel 9 clockwise or counterclockwise around the same vertical center line, thereby sequentially pulling the photovoltaic panel 8 and the photovoltaic panel 7 to unfold or retract through the convex rod-sliding groove pair. The inverted L-shaped baffle 3 also serves as a motor protective cover and a rain shield, preventing seawater and rainwater from entering the motor and sliding pair, realizing an electromechanical integrated sealing design, and improving system reliability and service life.

[0039] This invention adds a mounting base with a servo motor, which drives the rotating shaft to rotate the photovoltaic panel three times, enabling the photovoltaic panel module to automatically unfold and retract. The inverted L-shaped baffle also has protective and waterproof functions, improving the system's reliability and service life.

[0040] According to one embodiment of the present invention, photovoltaic panel 7, photovoltaic panel 8, and photovoltaic panel 9 are all fan-shaped structures.

[0041] In this embodiment, photovoltaic panel 7, photovoltaic panel 8, and photovoltaic panel 9 are all designed as fan-shaped structures with the same central angle. The three are stacked from top to bottom on the same vertical axis. When unfolded, they are rotated in a staggered manner along the circumference. The outer edges of the fan shapes can be seamlessly spliced ​​to form an approximately circular light-receiving surface, maximizing the solar radiation capture per unit area. When retracted, the fan-shaped outlines of each photovoltaic panel overlap, with the same outer diameter, making it easy to embed the whole into the shading cavity below the top surface of the inverted L-shaped baffle 3, reducing radial dimensions and wind resistance. The fan-shaped geometry also makes the trajectories of the protruding rod 10 and the arc-shaped sliding groove 11 naturally concentric, reducing the friction and jamming risk of the sliding pair, improving the smoothness and reliability of the retraction and extension movements, and adapting to the curved surface arrangement of the patrol boat top and the requirements for wind and wave resistance.

[0042] This invention designs three photovoltaic panels into a fan-shaped structure with the same central angle. When unfolded, they can be seamlessly spliced ​​into an approximately circular light-receiving surface to maximize the capture of solar radiation. When folded, they are easy to embed into the shading cavity to reduce radial dimensions and wind resistance, and also reduce the risk of friction jamming of sliding pairs, thus improving the smoothness and reliability of unfolding and folding.

[0043] Example 2 According to one embodiment of the present utility model, an anti-submersion patrol boat includes a patrol boat body 1, a bilge keel 2 is installed on the bilge of the patrol boat body 1, a baffle 3 and a mounting seat 4 are installed on the upper end of the patrol boat body 1, and the side of the baffle 3 and the side of the mounting seat 4 are connected to each other. The mounting base 4 houses a servo motor 12, the output of which is connected to a rotating shaft 13. A photovoltaic panel 9 is mounted on the upper end of the rotating shaft 13. A support column 5 is connected to the top of the baffle 3. A limit ring 6 is provided on the side wall of the support column 5. A photovoltaic panel 7 is connected to the outer edge of the upper limit ring 6, and a photovoltaic panel 8 is connected to the outer edge of the lower limit ring 6. A protruding rod 10 is installed at one end of photovoltaic panel 7, photovoltaic panel 8 and photovoltaic panel 9, and a sliding groove 11 is opened on the lower side of baffle 3, photovoltaic panel 7 and photovoltaic panel 8.

[0044] There is a gap between the support column 5 and the photovoltaic panel 9. The rotation center point of the photovoltaic panel 9 is on the same vertical line as the rotation center points of the photovoltaic panel 7 and the photovoltaic panel 8. This allows the photovoltaic panels 7, 8 and 9 to rotate smoothly and avoid jamming.

[0045] Photovoltaic panel 7 and photovoltaic panel 8 are both connected to the support column 5 by limiting ring 6 to form a rotating structure. Photovoltaic panel 7, photovoltaic panel 8 and photovoltaic panel 9 are distributed from top to bottom. There are gaps between photovoltaic panel 7, photovoltaic panel 8 and photovoltaic panel 9, which can be flexibly extended and retracted.

[0046] Photovoltaic panel 7, photovoltaic panel 8, and photovoltaic panel 9 are all fan-shaped structures. The highest point of photovoltaic panel 7 is lower than the lowest point of the upper surface of baffle 3, so photovoltaic panel 7, photovoltaic panel 8, and photovoltaic panel 9 can be easily folded into baffle 3 for shading and protection.

[0047] A protruding rod 10 is installed at one end of photovoltaic panel 7, photovoltaic panel 8 and photovoltaic panel 9. A sliding groove 11 is opened on the lower side of baffle 3, photovoltaic panel 7 and photovoltaic panel 8. Preferably, the protruding rod 10 extends into the sliding groove 11 to slide. The sliding groove 11 has an arc-shaped structure, and the photovoltaic panel can be smoothly unfolded in a circular trajectory by using the protruding rod 10.

[0048] The arc center of the slide groove 11 is on the same vertical line as the rotation center of photovoltaic panel 7, photovoltaic panel 8 and photovoltaic panel 9. When photovoltaic panel 7, photovoltaic panel 8 and photovoltaic panel 9 rotate and retract, the protruding rod 10 slides smoothly in the slide groove 11 to avoid jamming.

[0049] The working principle of this utility model is as follows: When using the anti-overturning patrol boat of this utility model, the bilge of the patrol boat body 1 is equipped with a bilge keel 2. When the boat rolls, the bilge keel 2 disturbs the flow field around the hull, causing the boat to generate additional damping. By increasing the roll damping, the purpose of reducing roll is achieved, thereby realizing the anti-overturning effect of the patrol boat. The upper end of the patrol boat body 1 is equipped with a baffle 3 and a mounting base 4. In clear weather, the servo motor 12 can be powered on and operated, controlling its forward rotation. This, in turn, controls the rotating shaft 13 connected to the output end to rotate counterclockwise, thereby controlling the photovoltaic panel 9 connected to the upper end of the rotating shaft 13 to rotate counterclockwise. The photovoltaic panel 9 gradually rotates out of the baffle 3. Simultaneously, the protruding rod 10 connected to the end of the photovoltaic panel 9 slides within the groove 11 opened on the lower side of the photovoltaic panel 8 until the protruding rod 10 slides to one end of the groove 11, which can then pull the photovoltaic panel 8 to rotate, gradually rotating it out of the baffle 3. When the protruding rod 10 connected to the end of the photovoltaic panel 8 slides in the groove 11 opened on the lower side of the photovoltaic panel 7, until the protruding rod 10 slides to one end of the groove 11, the photovoltaic panel 7 can be pulled to rotate, and the photovoltaic panel 7 is gradually rotated out of the baffle 3. At the same time, the protruding rod 10 connected to the end of the photovoltaic panel 7 slides in the groove 11 opened on the lower side of the baffle 3, and the photovoltaic panel assembly is unfolded. The photovoltaic panel converts solar energy into electrical energy, and outputs the electrical energy to the patrol boat's battery through the inverter for storage and supply to the patrol boat for use. In rainy weather, the servo motor 12 can be reversed, thereby controlling the rotating shaft 13 to drive the photovoltaic panel 9 to rotate clockwise. The protruding rod 10 connected to the end of the photovoltaic panel 9 slides in the groove 11 opened on the lower side of the photovoltaic panel 8 until the protruding rod 10 slides to the other end of the groove 11, which can push the photovoltaic panel 8 to rotate clockwise. The protruding rod 10 connected to the end of the photovoltaic panel 8 slides in the groove 11 opened on the lower side of the photovoltaic panel 7 until the protruding rod 10 slides to the other end of the groove 11, which can push the photovoltaic panel 7 to rotate clockwise, folding the photovoltaic panel 7, photovoltaic panel 8 and photovoltaic panel 9 into the baffle 3, using the baffle 3 to shield and protect them.

[0050] This invention, by installing rotatable photovoltaic panel components on the patrol boat body and combining them with a bilge keel anti-roll design, allows the photovoltaic panels to be deployed in sunny weather to convert solar energy into electrical energy and store it for use by the patrol boat. In cloudy or rainy weather, the fan-shaped photovoltaic panel components can be folded into the baffle for shielding and protection. This effectively solves the problems of traditional photovoltaic panels being directly exposed and unable to be stored, unable to be shielded and protected, and easily damaged, thus affecting their service life. At the same time, it ensures the patrol boat's anti-capsulation effect.
