Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic power generation platforms, and in particular relates to an offshore photovoltaic power generation platform. Background Art

[0002] Offshore photovoltaic power generation platforms are a new type of energy facility that applies photovoltaic power generation technology to the marine environment. By installing photovoltaic modules on floating or fixed platforms at sea, they use solar energy to generate electricity. This has the advantages of efficiently utilizing ocean space, not occupying land resources, and improving photovoltaic power generation efficiency.

[0003] As a modern energy facility, the offshore photovoltaic power generation platform is mainly composed of several key parts, including floating structure, photovoltaic modules, support system, electrical system, mooring system and protection system. During the installation process, the photovoltaic modules need to be accurately installed on the floating structure first, and then through the connection of the auxiliary float, multiple groups of photovoltaic modules and the floating structure are effectively connected together to ensure the stability of the entire structure. Finally, the entire power generation platform is fixed in an appropriate position with the help of the mooring system to adapt to the complexity of the marine environment.

[0004] However, since the floating structure is placed above the water surface, there are abundant marine life in the surrounding seawater. These organisms grow and attach to the floating structure. Over time, their weight will gradually increase, causing the load on the floating structure to gradually increase, eventually causing the floating structure to sink, affecting the stability and safety of the photovoltaic power generation platform. Summary of the Invention

[0005] The purpose of the present invention is to provide an offshore photovoltaic power generation platform to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: an offshore photovoltaic power generation platform, comprising a plurality of photovoltaic modules, each of which is evenly arranged, the bottom end of each photovoltaic module being connected to a floating body via a bracket, each of the floating bodies being connected to each other via an auxiliary floating body, each of the floating bodies being provided with a bottom plate at the bottom end, a knocking assembly being provided at the bottom end of the bottom plate, and the bottom plate being connected to the floating body via a moving assembly;

[0007] In which, the tapping assembly includes a tapping plate arranged at the bottom end of the base plate, and there are four tapping plates. The four tapping plates are rotatably connected to the base plate through a first rotating shaft, and both ends of each first rotating shaft are fixedly installed with a first bevel gear, and the bottom end of one of the first bevel gears is meshed and connected with a second bevel gear, and the bottom end of the second bevel gear is fixedly connected with a second rotating shaft, and the bottom end of the second rotating shaft is fixedly installed with a gear, and one side of the gear is meshed and connected with a rack plate, and the rack plate is slidably installed on the inner wall of the base plate, and one end of the rack plate is fixedly connected to a movable plate, and the inside of the movable plate is slidably connected with a slider, and one end of the slider is fixedly connected to the rotating plate, and a third rotating shaft is fixedly installed on one side of the rotating plate, and a motor is fixedly installed on the end of the third rotating shaft away from the rotating plate.

[0008] As a further technical solution of the present invention, through holes are opened inside the knocking plate, and the through holes are evenly distributed.

[0009] It makes the water flow smoother and reduces resistance, which is beneficial to improving the maneuverability and flexibility of the knocking board.

[0010] As a further technical solution of the present invention, a first protrusion is fixedly installed on the side wall of the knocking plate, and a plurality of first protrusions are provided.

[0011] When the knocking plate rotates and knocks the bottom plate, the knocking plate drives the end of the first protrusion to contact the bottom plate, which helps to destroy the adhesion between the microorganisms and the bottom plate.

[0012] As a further technical solution of the present invention, a second protrusion is slidably installed inside the knocking plate, and a second spring is provided between the second protrusion and the knocking plate.

[0013] When the second protrusion encounters a hard object, such as a shellfish attached to the bottom of the bottom plate, the elasticity of the second spring can buffer part of the impact force, thereby extending the service life.

[0014] As a further technical solution of the present invention, a third protrusion is provided on the side wall of the knocking plate, baffles are fixedly connected on both sides of the third protrusion, a slide is fixedly installed on one side of the third protrusion, the slide is slidably installed inside the knocking plate, and a first spring is provided between the slide and the knocking plate.

[0015] The ability to move left and right during striking helps ensure that the third bump always maintains optimal contact with the striking surface during striking, thereby improving the striking effect;

[0016] By cooperating with the first protrusion, the second protrusion and the third protrusion, the protrusions on the side wall of the tapping plate have multiple implementation modes, which can adapt to different microorganisms attached to the bottom of the base plate, thereby improving the cleaning effect.

[0017] As a further technical solution of the present invention, the moving component includes a connecting plate slidably installed inside the float, the bottom end of the connecting plate is fixedly connected to a connecting rod, the bottom end of the connecting rod is fixedly connected to the bottom plate, an electromagnet is arranged under the connecting plate, the electromagnet is fixedly installed inside the float, and a knocking component is arranged on one side of the float.

[0018] When the knocking plate knocks, it can be activated by the electromagnet to generate an adsorption force on the connecting plate, so that the connecting plate moves and fits with the electromagnet. The movement of the connecting plate drives the movement of the connecting rod, and the movement of the connecting rod drives the movement of the bottom plate, so that the bottom plate moves to the side away from the floating body and separates from it, reducing the impact force of the knocking plate on the floating body when knocking, thereby ensuring the stability of the photovoltaic power generation platform.

[0019] As a further technical solution of the present invention, a vibration motor is installed inside the base plate.

[0020] The vibration motor is activated to make the bottom plate vibrate, and the vibration can be transmitted to the surface of the bottom plate, further destroying the attachment structure of microorganisms, and cooperating with the tapping of the tapping plate to improve the cleaning effect of the microorganisms attached to the bottom of the bottom plate.

[0021] As a further technical solution of the present invention, a tension spring is provided at the top end of the connecting plate.

[0022] When the connecting plate moves, the tension spring deforms and stores elastic potential energy. When the microorganisms attached to the bottom of the base plate are cleaned, the electromagnet is powered off, and the elastic potential energy is released through the tension spring to move the connecting plate back to its original position. At the same time, the tension spring can cushion and reduce shock when the tapping plate is tapped, further improving the stability of the photovoltaic power generation platform.

[0023] As a further technical solution of the present invention, a damper is installed inside the tension spring, and the damper is arranged inside the float.

[0024] Reduce the impact and vibration on the floating body, and further prevent the vibration from being transmitted to the photovoltaic power generation platform.

[0025] As a further technical solution of the present invention, the knocking assembly includes a gravity block arranged on one side of the floating body, the gravity blocks are evenly arranged, and the top of each gravity block is fixedly connected to a connecting rope, and the end of the connecting rope away from the gravity block is fixedly installed on the side wall of the connecting plate, and a fourth rotating shaft is provided inside the connecting rope, and the fourth rotating shaft is rotatably installed inside the floating body, and the outer wall of the fourth rotating shaft is provided with a coil spring.

[0026] When cleaning the microorganisms attached to the bottom of the bottom plate, the connecting plate moves downward, driving one end of the connecting rope to move, and the gravity block moves downward through its own gravity, so that the gravity block moves down from one side of the float to one side of the knocking plate. When the knocking plate rotates, the side wall contacts the gravity block, causing the gravity block to knock on the side wall of the knocking plate. This can not only clean the microorganisms attached to the knocking plate itself, but also prevent some microorganisms from attaching to the surface through the water flow during the knocking of the knocking plate on the bottom plate, thereby improving the stability and reliability of the knocking plate when knocking.

[0027] The beneficial effects of the present invention are as follows:

[0028] 1. The present invention sets a knocking assembly. When it is necessary to clean the microorganisms attached to the bottom of the bottom plate, the motor is first started by controlling the PLC. The start of the motor drives the rotation of the third rotating shaft, the rotation of the third rotating shaft drives the rotation of the rotating plate, the rotation of the rotating plate drives the rotation of the slider, the rotation of the slider drives the moving plate to slide back and forth inside the knocking plate, the movement of the moving plate drives the movement of the rack plate, the movement of the rack plate drives the gear to rotate, the rotation of the gear drives the second rotating shaft to rotate, the rotation of the second rotating shaft drives the second bevel gear to rotate, the rotation of the second bevel gear drives the first bevel gear to rotate, and the rotation of the first bevel gear drives the first The rotating shaft rotates, and the rotation of the first rotating shaft drives the knocking plate to rotate. The reciprocating sliding of the moving plate drives the knocking plate to rotate reciprocally, so that the knocking plate rotates to one side of the bottom plate to knock on the bottom plate, thereby cleaning the microorganisms attached to the bottom of the bottom plate, avoiding the fact that the floating structure is placed above the water surface and the surrounding seawater is relatively rich in marine life. These organisms grow and attach to the floating body. With the passage of time, their weight will gradually increase, thereby causing the weight of the floating body to gradually increase, and eventually causing the floating body to sink, affecting the stability and safety of the photovoltaic power generation platform. Cleaning the microorganisms attached to the bottom of the bottom plate improves the stability and safety of the photovoltaic power generation platform.

[0029] 2. The present invention is provided with a moving component. When the knocking plate knocks, it can be activated by the electromagnet to generate an adsorption force on the connecting plate, so that the connecting plate moves and fits with the electromagnet. The movement of the connecting plate drives the movement of the connecting rod, and the movement of the connecting rod drives the movement of the bottom plate, so that the bottom plate moves to the side away from the floating body and separates from it, reducing the impact force of the knocking plate on the floating body when knocking, thereby ensuring the stability of the photovoltaic power generation platform.

[0030] 3. Through the setting of the knocking component, the present invention cleans the microorganisms attached to the bottom of the base plate. When the connecting plate moves downward, it drives one end of the connecting rope to move. The gravity block moves downward due to its own gravity, so that the gravity block moves down from one side of the float to one side of the knocking plate. When the knocking plate rotates, the side wall contacts the gravity block, causing the gravity block to knock on the side wall of the knocking plate. This can not only clean the microorganisms attached to the knocking plate itself, but also prevent some microorganisms from attaching to the surface through water flow during the knocking of the knocking plate on the base plate, thereby improving the stability and reliability of the knocking plate when knocking.

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 making creative efforts are within the scope of protection of the present invention.

[0043] like Figures 1 to 10 As shown, in an embodiment of the present invention, an offshore photovoltaic power generation platform includes a photovoltaic module 1, wherein a plurality of photovoltaic modules 1 are evenly arranged, the bottom end of each photovoltaic module 1 is connected to a floating body 3 via a bracket 2, each floating body 3 is connected to each other via an auxiliary floating body 4, and the bottom end of each floating body 3 is provided with a bottom plate 5, the bottom end of the bottom plate 5 is provided with a knocking assembly, and the bottom plate 5 is connected to the floating body 3 via a moving assembly;

[0044] Among them, the tapping assembly includes a tapping plate 6 arranged at the bottom end of the base plate 5, and there are four tapping plates 6. The four tapping plates 6 are rotatably connected to the base plate 5 through the first rotating shaft 7. Both ends of each first rotating shaft 7 are fixedly installed with a first bevel gear 8, and the bottom end of one of the first bevel gears 8 is meshed and connected with the second bevel gear 9, and the bottom end of the second bevel gear 9 is fixedly connected with the second rotating shaft 10. The bottom end of the second rotating shaft 10 is fixedly installed with a gear 11, and one side of the gear 11 is meshed and connected with a rack plate 12, and the rack plate 12 is slidably installed on the inner wall of the base plate 5, and one end of the rack plate 12 is fixedly connected to a moving plate 13, and the inside of the moving plate 13 is slidably connected with a slider 14, and one end of the slider 14 is fixedly connected to a rotating plate 15, and one side of the rotating plate 15 is fixedly installed with a third rotating shaft 16, and the end of the third rotating shaft 16 away from the rotating plate 15 is fixedly installed with a motor 17.

[0045] Through the setting of the tapping component, when it is necessary to clean the microorganisms attached to the bottom of the base plate 5, the motor 17 is first started by the PLC control, and the start of the motor 17 drives the rotation of the third rotating shaft 16, and the rotation of the third rotating shaft 16 drives the rotation of the rotating plate 15, and the rotation of the rotating plate 15 drives the rotation of the slider 14, and the rotation of the slider 14 drives the moving plate 13 to slide back and forth inside the tapping plate 6, and the movement of the moving plate 13 drives the movement of the rack plate 12, and the movement of the rack plate 12 drives the gear 11 to rotate, and the rotation of the gear 11 drives the second rotating shaft 10 to rotate, and the rotation of the second rotating shaft 10 drives the second bevel gear 9 to rotate, and the rotation of the second bevel gear 9 drives the first bevel gear 8 to rotate, and the first bevel gear The rotation of the wheel 8 drives the first rotating shaft 7 to rotate, and the rotation of the first rotating shaft 7 drives the knocking plate 6 to rotate. The reciprocating sliding of the movable plate 13 drives the knocking plate 6 to rotate reciprocally, so that the knocking plate 6 rotates to one side of the bottom plate 5 to knock on the bottom plate 5, thereby cleaning the microorganisms attached to the bottom of the bottom plate 5, avoiding the fact that the floating body 3 structure is placed above the water surface and the surrounding seawater is relatively rich in marine life. These organisms grow and attach to the floating body 3. With the passage of time, their weight will gradually increase, thereby causing the load of the floating body 3 to gradually increase, and eventually causing the floating body 3 to sink, affecting the stability and safety of the photovoltaic power generation platform. Cleaning the microorganisms attached to the bottom of the bottom plate 5 improves the stability and safety of the photovoltaic power generation platform.

[0046] like Figures 1 to 10 As shown, through holes 20 are opened inside the knocking plate 6, and the through holes 20 are evenly distributed.

[0047] This makes the water flow smoother and reduces resistance, which is beneficial to improving the maneuverability and flexibility of the knocking plate 6.

[0048] like Figures 1 to 10 As shown, a first protrusion 19 is fixedly mounted on the side wall of the knocking plate 6 , and a plurality of first protrusions 19 are provided.

[0049] The first protrusion 19 is set to be conical. When the knocking plate 6 rotates to knock on the bottom plate 5, the knocking plate 6 drives the end of the first protrusion 19 to contact the bottom plate 5, which helps to destroy the adhesion between the microorganisms and the bottom plate 5.

[0050] The air flow generated during the rotation of the tapping plate 6 may help to remove the detached microorganisms from the surface of the bottom plate 5.

[0051] like Figures 1 to 10 As shown, a second protrusion 34 is slidably installed inside the knocking plate 6, and a second spring 33 is provided between the second protrusion 34 and the knocking plate 6.

[0052] When the second protrusion 34 encounters a hard object, such as a shellfish attached to the bottom of the bottom plate 5, the elasticity of the second spring 33 can buffer part of the impact force, thereby extending the service life.

[0053] like Figures 1 to 10 As shown, a third protrusion 35 is provided on the side wall of the knocking plate 6, and a baffle 30 is fixedly connected to both sides of the third protrusion 35. A slide plate 31 is fixedly installed on one side of the third protrusion 35, and the slide plate 31 is slidably installed inside the knocking plate 6. A first spring 32 is provided between the slide plate 31 and the knocking plate 6.

[0054] The ability to move left and right during striking helps ensure that the third protrusion 35 always maintains optimal contact with the striking surface during the striking process, thereby improving the striking effect;

[0055] By cooperating with the first protrusion 19, the second protrusion 34 and the third protrusion 35, the protrusions on the side wall of the tapping plate 6 have multiple implementation modes, which can adapt to different microorganisms attached to the bottom of the bottom plate 5, thereby improving the cleaning effect.

[0056] like Figures 1 to 10 As shown, the moving component includes a connecting plate 22 slidably installed inside the float 3, the bottom end of the connecting plate 22 is fixedly connected to a connecting rod 23, the bottom end of the connecting rod 23 is fixedly connected to the bottom plate 5, an electromagnet 21 is arranged below the connecting plate 22, the electromagnet 21 is fixedly installed inside the float 3, and a knocking component is arranged on one side of the float 3.

[0057] The electromagnet 21 is magnetically connected to the connecting plate 22;

[0058] Through the setting of the moving component, when the knocking plate 6 knocks, the electromagnet 21 can be activated to generate an adsorption force on the connecting plate 22, so that the connecting plate 22 moves to fit with the electromagnet 21. The movement of the connecting plate 22 drives the movement of the connecting rod 23, and the movement of the connecting rod 23 drives the movement of the bottom plate 5, so that the bottom plate 5 moves to the side away from the floating body 3 and separates from it, reducing the impact force of the knocking plate 6 on the floating body 3 when knocking, thereby ensuring the stability of the photovoltaic power generation platform.

[0059] like Figures 1 to 10 As shown, a vibration motor 18 is installed inside the base plate 5.

[0060] When cleaning the microorganisms attached to the bottom of the bottom plate 5, the vibration motor 18 can be started to make the bottom plate 5 vibrate. The vibration can be transmitted to the surface of the bottom plate 5, further destroying the attachment structure of the microorganisms, and cooperating with the tapping of the tapping plate 6 to improve the cleaning effect of the microorganisms attached to the bottom of the bottom plate 5.

[0061] like Figures 1 to 10 As shown, a tension spring 24 is provided at the top end of the connecting plate 22 .

[0062] When the connecting plate 22 moves, the tension spring 24 deforms to store elastic potential energy. When the microorganisms attached to the bottom of the bottom plate 5 are cleaned, the electromagnet 21 is powered off, and the elastic potential energy is released by the tension spring 24 to move the connecting plate 22 back to its original position.

[0063] At the same time, the tension spring 24 can buffer and reduce shock when the knocking plate 6 is knocked, thereby further improving the stability of the photovoltaic power generation platform.

[0064] like Figures 1 to 10 As shown, a damper 25 is installed inside the tension spring 24 , and the damper 25 is arranged inside the floating body 3 .

[0065] Reduce the impact and vibration on the floating body 3, and further prevent the vibration from being transmitted to the photovoltaic power generation platform.

[0066] like Figures 1 to 10 As shown, the knocking assembly includes a gravity block 28 arranged on one side of the float 3. The gravity blocks 28 are evenly arranged. The top of each gravity block 28 is fixedly connected to a connecting rope 26. The end of the connecting rope 26 away from the gravity block 28 is fixedly installed on the side wall of the connecting plate 22. A fourth rotating shaft 27 is provided inside the connecting rope 26. The fourth rotating shaft 27 is rotatably installed inside the float 3, and a coil spring 29 is provided on the outer wall of the fourth rotating shaft 27.

[0067] Through the setting of the knocking component, when cleaning the microorganisms attached to the bottom of the bottom plate 5, the connecting plate 22 moves downward, driving one end of the connecting rope 26 to move, and the gravity block 28 moves downward through its own gravity, so that the gravity block 28 moves down from one side of the float 3 to one side of the knocking plate 6. When the knocking plate 6 rotates, the side wall contacts the gravity block 28, causing the gravity block 28 to knock on the side wall of the knocking plate 6, which can not only clean the microorganisms attached to the knocking plate 6 itself, but also prevent some microorganisms from attaching to the surface through the water flow during the knocking of the knocking plate 6 on the bottom plate 5, thereby improving the stability and reliability of the knocking plate 6 when knocking.

[0068] Working principle and usage process:

[0069] When it is necessary to clean the microorganisms attached to the bottom of the bottom plate 5, the electromagnet 21, the motor 17 and the vibration motor 18 are first started by the PLC. The start of the electromagnet 21 generates an adsorption force on the connecting plate 22, causing the connecting plate 22 to move and fit into the electromagnet 21. The movement of the connecting plate 22 drives the movement of the connecting rod 23, and the movement of the connecting rod 23 drives the movement of the bottom plate 5, causing the bottom plate 5 to move away from the floating body 3 and separate from it.

[0070] When the connecting plate 22 moves downward, the gravity block 28 moves downward by its own gravity, so that the gravity block 28 moves downward from one side of the floating body 3 to one side of the knocking plate 6;

[0071] The start of the motor 17 drives the rotation of the third rotating shaft 16, and the rotation of the third rotating shaft 16 drives the rotation of the rotating plate 15. The rotation of the rotating plate 15 drives the rotation of the slider 14. The rotation of the slider 14 drives the movable plate 13 to slide back and forth inside the knocking plate 6. The movement of the movable plate 13 drives the movement of the rack plate 12. The movement of the rack plate 12 drives the gear 11 to rotate. The rotation of the gear 11 drives the second rotating shaft 10 to rotate. The rotation of the second rotating shaft 10 drives the second bevel gear 9 to rotate. The rotation of the second bevel gear 9 drives the first bevel gear 8 to rotate. The rotation of the first bevel gear 8 drives the first rotating shaft 7 to rotate. The rotation of the first rotating shaft 7 drives the knocking plate 6 to rotate. The reciprocating sliding of the movable plate 13 drives the knocking plate 6 to rotate back and forth, causing the knocking plate 6 to rotate toward one side of the bottom plate 5, knocking the bottom plate 5, and contacting the gravity block 28, causing the gravity block 28 to knock on the side wall of the knocking plate 6.

[0072] The start of the vibration motor 18 causes the bottom plate 5 to vibrate, and the vibration can be transmitted to the surface of the bottom plate 5, and cooperate with the tapping of the tapping plate 6 to clean the microorganisms attached to the bottom of the bottom plate 5.

[0073] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
