[0002] The main benefits of installing photovoltaics on ships are as follows: environmental protection and energy saving: using solar energy to generate electricity does not produce greenhouse gas emissions such as carbon dioxide, reducing carbon emissions and saving energy: solar energy is a renewable energy source that is inexhaustible and can effectively reduce dependence on traditional fossil energy.

[0003] At present, the photovoltaic modules installed on traditional ships for photovoltaic power generation devices are generally installed in a fixed manner. Although the fixed installation can improve the stability of the photovoltaic modules, when the ship is sailing at sea, the weather at sea is changeable and it is easy to encounter strong winds or heavy rain. The photovoltaic modules cannot be protected in strong winds or heavy rain. The dense raindrops continue to impact the surface of the photovoltaic panels, which will cause a certain degree of physical damage to the photovoltaic panels, such as wearing the surface coating of the photovoltaic panels, which may affect its photoelectric conversion efficiency in the long term. Strong winds will cause the photovoltaic modules to be blown off and damaged. If the ship is sailing or anchored in windy weather, the strong wind may loosen the connection between the photovoltaic modules and the installation site, or even directly blow the modules away from their original position, causing the modules to be cracked, scratched and other physical damage, thereby affecting their normal power generation function. Summary of the invention

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example 1

[0027] A self-regulating photovoltaic power generation device for a ship comprises a frame 1 and photovoltaic modules 2 arranged in rows inside the frame 1, a storage cavity 3 is fixedly connected to the bottom of the frame 1, and a protective plate 4 is symmetrically arranged at the bottom of the frame 1. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, in the present application, the photovoltaic module 2 is the core component of the photovoltaic power generation device, which is responsible for converting solar energy into direct current. After the photovoltaic module 2 is installed, an external battery pack used in conjunction with the photovoltaic module 2 must be installed. The battery pack is used to store the electrical energy generated by the photovoltaic module 2. The battery pack must be installed with a battery controller 18 to control the charging and discharging process of the battery and protect the battery from damage such as overcharging, over-discharging and overcharging. The inverter converts direct current into alternating current so that it can be connected to the power grid or used for household and industrial electrical equipment. Finally, an AC distribution cabinet matching the photovoltaic module 2 is installed to distribute and control the output of alternating current. The storage cavity 3 is used to store the folded photovoltaic module 2. With the use of the protective plate 4, a protective space can be formed to protect the folded and stored photovoltaic module 2.

[0028] Furthermore, the surface of the frame 1 is provided with a piezoelectric raindrop sensor 8 and a wind speed sensor 19, both of which are fixedly connected to the surface of the frame 1 through a mounting member, and the surface of the storage cavity 3 is equipped with a controller 18, such as Figure 1 , Figure 3 and Figure 7 As shown, the piezoelectric raindrop sensor 8 and the wind speed sensor 19 are both installed on the frame 1. The piezoelectric raindrop sensor 8 can detect the amount of rainfall in rainy weather, and the wind speed sensor 19 can check the amount of wind in the external environment. The controller 18 is used to receive the detection data of the piezoelectric raindrop sensor 8 and the wind speed sensor 19, and is used to control the folding and storage of the photovoltaic assembly 2.

[0029] The frame 1 is symmetrically provided with sliding grooves 5 inside, and a bidirectional threaded rod 6 is rotated inside the sliding grooves 5. The surface of the bidirectional threaded rod 6 is symmetrically screwed with a sliding block 7 slidably connected to the sliding grooves 5. The sliding block 7 is rotated on the side close to the photovoltaic component 2 to fix the outermost photovoltaic component 2. The top of the storage cavity 3 is provided with a barrel rod 10 for active connection between two adjacent photovoltaic components 2. The frame 1 is symmetrically fixed with an articulated seat 11 hinged to the photovoltaic component 2 inside. A transmission mechanism 12 and a driving mechanism 13 are respectively provided at one end of the frame 1. A plurality of connecting members 22 are rotated at both ends of the barrel rod 10. Two adjacent connecting members 22 are designed for alignment and are fixed to the photovoltaic component 2. A connecting bracket 20 is assembled on the top of the protective plate 4. The connecting bracket 20 is fixed to the bottom of the outermost photovoltaic component 2. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, when the piezoelectric raindrop sensor 8 and the wind speed sensor 19 detect the data of the rainfall and wind volume in the external environment and transmit them to the controller 18, the controller 18 determines whether the photovoltaic assembly 2 needs to be stored through the data. When the photovoltaic assembly 2 needs to be stored, the controller 18 controls the driving mechanism 13 to start, and the driving mechanism 13 starts to transmit the rotational force to the bidirectional threaded rod 6 through the transmission mechanism 12. The bidirectional threaded rod 6 is installed inside the sliding groove 5, and the sliding block 7 is screwed to the bidirectional threaded rod 6. When the rotational force is transmitted to the bidirectional threaded rod 6, the bidirectional threaded rod 6 can be driven to rotate, and the sliding block 7 slides with the sliding groove 5. Dynamic connection, the sliding block 7 is forced to make linear motion. In the present application, the preferred number of photovoltaic modules 2 is four, the hinge seat 11 is installed inside the frame 1, and there are two protrusions on the hinge seat 11, the two protrusions are hinged to the middle two of the four photovoltaic modules 2, and then, the two photovoltaic modules 2 in the middle of the frame 1 can be rotated at the axis of the hinge seat 11, the preferred number of the barrel rod 10 is two, respectively located between the side photovoltaic modules 2 and the middle photovoltaic modules 2, the connecting member 22 is installed on the barrel rod 10, the connecting member 22 is fixed to the photovoltaic module 2, and the connecting member 22 on the side photovoltaic module 2 is connected to the photovoltaic module 2 in the middle section The connecting piece 22 on the cylinder rod 10 is in the opposite direction to the direction on the cylinder rod 10. The connecting piece 22 can fix the side photovoltaic components 2 and the photovoltaic components 2 in the middle section on the cylinder rod 10. The side photovoltaic components 2 and the photovoltaic components 2 in the middle section can rotate with the cylinder rod 10 as the axis. The rotating column 9 is rotatably installed on the sliding block 7, and the other end of the rotating column 9 is fixed to the side photovoltaic components 2. When the bidirectional threaded rod 6 rotates, the sliding block 7 drives the rotating column 9 to move, and the two photovoltaic components 2 on the side move toward the two photovoltaic components 2 in the middle, while the height of the photovoltaic components 2 on the side remains unchanged, and the side photovoltaic components 2 are aligned with the photovoltaic components in the middle. The connection point of the components 2 is tilted at an angle along the axis. At this time, the two side photovoltaic components 2 and the two middle photovoltaic components 2 form a W structure. When continuing to fold, the four photovoltaic components 2 are parallel to each other. Since the two middle photovoltaic components 2 are fixed on the hinge seat 11 and do not move, the folded photovoltaic components 2 are all in the storage cavity 3. The protective plate 4 is installed on the photovoltaic components 2 on the side. When the two side photovoltaic components 2 are vertically stored in the storage cavity 3, the protective plate 4 and the storage cavity 3 are surrounded to form a protective space to protect the folded photovoltaic components 2 and reduce damage in windy and rainy weather.

[0030] The transmission mechanism 12 includes a transmission rod 121, one end of the bidirectional threaded rod 6 penetrates the outside of the frame 1 and is fixedly sleeved with a first bevel gear 122, the surface of the first bevel gear 122 is meshed with a second bevel gear 123 fixedly sleeved with the transmission rod 121, the driving mechanism 13 includes a servo motor 131, the servo motor 131 and the frame 1 are fixedly connected by a mounting member, a third bevel gear 132 is fixed to the output end of the servo motor 131, the surface of the third bevel gear 132 is meshed with a fourth bevel gear 133 fixedly sleeved with the transmission rod 121, and a fixed block 21 is symmetrically fixed to one end of the frame 1, and the fixed block 21 is rotatably connected to the transmission rod 121, such as Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, the servo motor 131 is installed on the frame 1, and the third bevel gear 132 is installed on the output end of the servo motor 131. When the servo motor 131 is controlled by the controller 18, the third bevel gear 132 can be driven to rotate. The fourth bevel gear 133 is installed on the transmission rod 121 and meshes with the third bevel gear 132. When the third bevel gear 132 rotates, the fourth bevel gear 133 can be driven to rotate, thereby driving the transmission rod 121 to rotate, and the second bevel gear 123 is installed on the transmission rod 121, and can be driven to rotate by the transmission rod 121. The first bevel gear 122 is fixed to one end of the bidirectional threaded rod 6 outside the frame 1 and meshes with the second bevel gear 123. The rotation of the second bevel gear 123 can drive the first bevel gear 122 to rotate, thereby achieving the purpose of the transmission rod 121 driving the two bidirectional threaded rods 6 to rotate.

[0031] The front of the storage chamber 3 is equipped with an air guide fan 14, the output end of the air guide fan 14 is connected to a three-way hose 15, one end of the two branches of the three-way hose 15 is connected to the cylinder rod 10, the surface of the cylinder rod 10 is symmetrically connected to the air guide cavity head 16, and the air inlet of the air guide fan 14 is equipped with a filter screen 17, such as Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the air guide fan 14 is installed on the storage chamber 3, and is used to transport external air to the inside of the three-way hose 15. The branch pipe of the three-way hose 15 is connected to the cylinder rod 10, so that the air transported by the air guide fan 14 can be transported to the inside of the cylinder rod 10. The air guide cavity head 16 is installed on the surface of the cylinder rod 10 and is connected to the inside of the cylinder rod 10. The air transported to the inside of the cylinder rod 10 can be discharged outward through the air guide cavity head 16. Because the air inlet of the air guide cavity head 16 is large and the air outlet is small, the wind flow is compressed and presents a jet to discharge from the air guide cavity head 16, which can blow away the dust on the photovoltaic module 2, and can also blow away the snowflakes on snowy days to prevent snow accumulation on the photovoltaic module 2.
