[0003] Unlike installing photovoltaic panels on land, which directly places the photovoltaic panels on the metal bracket and fastens them, installing photovoltaic panels on ships generally involves installing a metal frame on the ship and placing the photovoltaic panels inside the metal frame. In order to ensure the stability of the photovoltaic panels when the ship is in harsh environments such as at sea, the photovoltaic panels and the metal frame are generally fixed with bolts, which requires drilling holes on the outer surface of the metal frame and the frame of the photovoltaic panels. The bolts pass through the holes in the metal frame and the holes in the frame of the photovoltaic panels to achieve the purpose of fixation. Although it can achieve the purpose of installation with high stability, the number of holes punched on the metal frame and the frame of the photovoltaic panel is relatively large. Photovoltaic panels are installed on ships for use, because the marine environment is worse than that on land, and wave impact, salt spray corrosion, vibration and shaking may cause damage to the photovoltaic panels. The large number of bolts makes installation and disassembly extremely troublesome, and drilling holes on the frame of the photovoltaic panel can easily cause damage to the photovoltaic panel.

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.

[0027] Embodiment, this embodiment discloses a photovoltaic installation structure for ship power generation, including an installation frame 1 and a plurality of photovoltaic modules 2 placed inside the installation frame 1, a plurality of pressing plates 3 for fixing the photovoltaic modules 2 are arranged on the top of the installation frame 1, and a compartment seat 4 is symmetrically fixed to the bottom of the pressing plate 3, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, in the present application, the mounting frame 1 is used to place the photovoltaic module 2, the pressing plate 3 is used to limit the photovoltaic module 2 to prevent the photovoltaic module 2 from escaping from the mounting frame 1, and the compartment seat 4 is located between the two photovoltaic modules 2 to drive the pressing plate 3 to press the edges of the two photovoltaic modules 2.

[0028] Furthermore, a plurality of mounting seats 5 are provided at the bottom of the mounting frame 1, a groove body 11 is provided at the top of the mounting seat 5, a screw rod 12 is rotated inside the groove body 11, a connecting block 13 is screwed on the surface of the screw rod 12, a second support rod 14 is provided on the top of the connecting block 13, a transmission mechanism 15 is provided at the bottom of the mounting frame 1, the transmission mechanism 15 includes a transmission rod 20, one end of the screw rod 12 passes through the outside of the mounting seat 5 and is fixedly sleeved with a first bevel gear 21, a second bevel gear 22 whose number matches the first bevel gear 21 is fixedly sleeved on the surface of the transmission rod 20, and the second bevel gear 22 meshes with the first bevel gear 21, one end of the first support rod 6 and one end of the second support rod 14 are both hinged with a first connecting seat 28, the two first connecting seats 28 are both fixedly connected to the mounting frame 1, and a second connecting seat 29 hinged with the second support rod 14 is fixedly connected to the top of the connecting block 13, Figure 1 , Figure 4 and Figure 5As shown, the mounting seat 5 is used for supporting and fixing the first support rod 6, and the resistance reduction outer frame 30 is installed on the outside of the mounting frame 1. Its surface is triangular and has a certain slope, which can reduce the wind resistance of the mounting frame 1. The first support rod 6 is installed on the top of the mounting seat 5 and is hinged to the mounting frame 1 through the first connecting seat 28, so that the mounting frame 1 can be rotatably supported. The second support rod 14 connects the connecting block 13 and the mounting frame 1 together through a first connecting seat 28 and a second connecting seat 29. The mounting seat 5 supports the mounting frame 1 through the first support rod 6 and the second support rod 14. The screw rod 12 is installed in the inside of the groove body 11, and the screw rod 12 is screwed to the connecting block 13. The transmission rod 20 is installed on the mounting seat 5 at the bottom of the mounting frame 1. The first bevel gear 21 and the second bevel gear 22 are respectively installed on the screw rod 12 and the transmission rod 20, and the first bevel gear 21 and the second bevel gear 22 are meshed. When the transmission When the movable rod 20 rotates, the screw rod 12 can be driven to rotate under the action of the first bevel gear 21 and the second bevel gear 22. The rotation of the screw rod 12 drives the connecting block 13 inside the slot body 11 to move, and the connecting block 13 drives the second support rod 14 to move. Under the limitation of the first support rod 6, the installation frame 1 is adjusted at an angle with the hinge of the first support rod 6 as the axis, driving the photovoltaic component 2 to adjust the angle. When it is in bad weather such as strong winds, when the photovoltaic component 2 inside the frame is adjusted to a horizontal state, the contact area between the photovoltaic component 2 and the wind is reduced, which can reduce wind resistance and reduce damage to the photovoltaic component 2 caused by external environmental factors, thereby ensuring the normal structure of the photovoltaic component 2. When the weather is clear, the photovoltaic component 2 can be adjusted to a corresponding inclination state according to the time period of the day, thereby increasing the amount of sunlight received by the photovoltaic component 2 at different time periods, so that the photovoltaic component 2 can convert more solar energy into electrical energy during the day.

[0029] Further, guide blocks 23 are installed on both sides of the connecting block 13, guide grooves 24 are symmetrically opened inside the groove body 11, the guide blocks 23 and the guide grooves 24 are slidably connected, and multiple mounting ears 25 are fixedly connected on both sides of the mounting seat 5. The shape of the mounting ears 25 is L-shaped, and threaded mounting holes 26 are opened at the horizontal ends of the mounting ears 25. A fixed block 27 is fixedly connected to one end of the mounting seat 5 close to the transmission rod 20, and the fixed block 27 is rotatably connected to the transmission rod 20, such as Figure 1 and Figure 4As shown, the guide block 23 is installed on both sides of the connecting block 13, and the guide groove 24 is opened inside the groove body 11. The guide block 23 is slidably connected with the guide groove 24, which can convert the mechanical force of the connecting block 13 driven by the screw rod 12 to rotate into a straight motion force, and reduce the friction force when the connecting block 13 moves. The mounting ears 25 are designed on both sides of the mounting seat 5. The mounting ears 25 are provided with threaded mounting holes 26 for fixing the mounting seat 5. The mounting seat 5 can be fixed on the platform of the ship through the mounting holes. The fixing block 27 is installed on the mounting seat 5. The fixing block 27 and the transmission rod 20 are preferably rotatably connected by bearings. The fixing block 27 can limit the rotation of the transmission rod 20 to improve the stability of the transmission rod 20 when it rotates.

[0030] A limit card block 7 is arranged inside the compartment seat 4, and a limit card slot 8 slidably connected to the limit card block 7 is symmetrically opened inside the mounting frame 1. A support spring 10 is arranged inside the compartment seat 4, and the two ends of the support spring 10 contact the limit card block 7 and the inner wall of the compartment seat 4 respectively. Figure 2 , Figure 3 and Figure 6 As shown, the limit card block 7 is installed inside the cavity seat 4, the limit card slot 8 is opened inside the mounting frame 1, and the support spring 10 is inside the cavity seat 4, which is used to provide support force for the limit card block 7. When the pressure plate 3 drives the cavity seat 4 to move into the mounting frame 1, the limit card block 7 inside the cavity seat 4 is pressed by the wall of the mounting frame 1 to move into the cavity seat 4. When the cavity seat 4 drives the limit card block 7 to move to the limit card slot 8, the limit card block 7 is pushed out of the cavity seat 4 by the support spring 10. Because the inclined surface of the limit card block 7 cooperates with the inclined surface of the limit card slot 8, the cavity seat 4 can be driven to pull downward, so that the cavity seat 4 pulls the pressure plate 3 to limit the photovoltaic component 2. This design can directly press the pressure plate 3 on the top of the photovoltaic component 2, so that the pressure plate 3 and the mounting frame 1 form a whole. When fixing the photovoltaic component 2, there is no need to drill holes, which avoids the trouble of installation and disassembly and prevents damage to the photovoltaic component 2.

[0031] The top and bottom of the limit block 7 are both equipped with guide blocks 16, and the interior of the compartment seat 4 is provided with a guide groove 17 slidably connected to the guide block 16. One end of the limit block 7 inside the compartment seat 4 is fixedly connected to a connecting slide rod 9, and a support spring 10 is sleeved on the surface of the connecting slide rod 9. A through groove 18 is symmetrically provided on the top of the pressure plate 3. One end of the connecting slide rod 9 passes through the through groove 18 to one end of the pressure plate 3 and is screwed to a limit cap 19. Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, the guide block 16 is installed on the limit block 7, and the guide groove 17 is opened inside the compartment seat 4 and is slidably connected with the guide block 16, so that the limit block 7 can be moved and limited when the limit block 7 moves and the friction force during its movement can be reduced. The connecting slide bar 9 is installed at one end of the limit block 7 inside the compartment seat 4, which is used to support and fix the support spring 10. The through groove 18 is opened on the pressure plate 3, which is used to provide a passage for the connecting slide bar 9 to pass through. One end of the connecting slide bar 9 passes through the through groove 18 from the inside of the compartment seat 4 and then passes through the through groove 18 to one end of the pressure plate 3, and the limiting cap 19 is screwed on this end. After the limiting cap 19 contacts the pressure plate 3, the connecting slide bar 9 can be limited, and the connecting slide bar 9 cannot move. The limit block 7 inside the compartment seat 4 is limited by the connecting slide bar 9 and cannot move, so that the pressure plate 3 is at the top of the photovoltaic component 2 and forms a whole with the mounting frame 1, so as to limit the photovoltaic component 2 and improve the stability of the fixation of the photovoltaic component 2.

[0032] Specifically, after the photovoltaic component 2 is installed inside the installation frame 1, the compartment seat 4 of the pressure plate 3 is placed between the two photovoltaic components 2 and moved downward. When the compartment seat 4 drives the limit block 7 to move to the limit slot 8, the limit block 7 is pushed out of the compartment seat 4 by the support spring 10. Because the inclined surface of the limit block 7 cooperates with the inclined surface of the limit slot 8, the compartment seat 4 can be driven to pull downward, so that the compartment seat 4 pulls the pressure plate 3 to limit the photovoltaic component 2. When the angle of the photovoltaic component 2 needs to be adjusted, the transmission rod 20 is rotated to drive the first bevel gear 21 and the second bevel gear 22 to rotate, and the transmission rod 20 drives the screw rod 12 to rotate. The rotation of the screw rod 12 drives the connecting block 13 inside the groove body 11 to move, and the connecting block 13 drives the second support rod 14 to move. Under the limitation of the first support rod 6, the installation frame 1 adjusts the angle with the hinge of the first support rod 6 as the axis to complete the response to different weather.
