Description

Technical Field

[0001] The present invention belongs to the technical field of offshore photovoltaic equipment, in particular to an offshore photovoltaic equipment. Background Art

[0002] As a reliable and widely applicable renewable energy source, solar energy is the best choice for people to replace non-renewable energy. Due to the continuous growth of population, the available land area is getting smaller and smaller, and the use of solar energy requires a lot of space. Therefore, the vast and uninhabited sea is undoubtedly the best place for solar power generation.

[0003] A patent with announcement number CN118928676B discloses a photovoltaic panel bracket and offshore photovoltaic power generation equipment. When the device is performing photovoltaic power generation, the photovoltaic panel bracket can increase the structural strength of the photovoltaic panel to protect the photovoltaic panel. At the same time, the protective strips and protective shells protect the photovoltaic panel to prevent floating debris on the water surface from damaging the edge of the photovoltaic panel. The protection effect is good and the service life is long. The photovoltaic panel has an inclination with the horizontal plane, and the protective shell and the protective strips are combined into a whole, which can prevent floating debris from hooking on the photovoltaic panel and affecting photovoltaic power generation. At the same time, when the wind and waves at sea are too strong or a storm occurs, the two sets of photovoltaic brackets are buckled together using two protective shells, so that the photovoltaic panel is wrapped and protected within the two protective shells and firmly locked to prevent the photovoltaic panel from being damaged by the impact of wind and waves. After closing, the buckling is tight, firm and reliable, and the protection effect is good. At the same time, two buffer plates are used to support and buffer the photovoltaic panel to prevent the photovoltaic panel from being damaged by collision inside the equipment due to violent shaking of the equipment.

[0004] There are still some problems in the actual application of the above scheme. When laying offshore photovoltaic equipment on the coast, the photovoltaic equipment will become a resting place for birds such as seagulls, which will cause the feces, feathers and weeds produced by the nesting of seagulls and other birds to cause garbage and dirt to accumulate on the surface of the photovoltaic panels. Excessive accumulation of bird droppings will affect the power generation of the photovoltaic panels, especially after the bird droppings are dried by the sun, the bird droppings will stick to the surface of the photovoltaic panels and solidify. It is difficult to clean the dried and solidified bird droppings with a broom alone. Moreover, the bird droppings will remain on the photovoltaic equipment for a long time, which will cause erosion to the photovoltaic equipment and affect the power generation performance and service life of the photovoltaic equipment.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] Example 1: Figures 1 to 8 As shown, an embodiment of the present invention described in an above-water photovoltaic device includes a frame 1, wherein air flotation blocks 2 are provided at the four corners of the frame 1, and slots 27 are provided at both ends of the frame 1. The frame 1 is connected to other frames 1 through the slots 27. Mounting blocks 3 are provided at both ends of the frame 1, and mounting brackets 4 are inserted into the inner cavity of the mounting blocks 3. A photovoltaic support plate 5 is rotatably provided between the mounting brackets 4. A photovoltaic panel 7 is installed in the upper end of the photovoltaic support plate 5, and a cleaning component 8 is provided inside the photovoltaic support plate 5. The cleaning assembly 8 includes a chute 81 provided at the lower end of the photovoltaic support plate 5, with fixed slide posts 82 installed on both sides of the inner cavity of the chute 81. A reciprocating sliding frame 84 is provided on the outer side of the fixed slide post 82, and the sliding frame 84 drives the cleaning rod 85 fixed at the upper end to move synchronously, so as to clean the surface of the photovoltaic panel 7 from dirt such as bird droppings. The inner cavity of the frame 1 is provided with a buoyancy lowering component, and the buoyancy lowering component includes a buoy 11 sliding in the inner cavity of the frame 1. Four third traction ropes 20 are fixed to the outside of the buoy 11, two of which pass through the frame 1 and are fixed with a slide 19 at one end, and the third traction ropes 20 are used to drive the slide 19 to reciprocate and pump seawater to form waves.

[0024] Specifically, in the prior art, a floating board is usually laid in Shanghai, and then a support frame is installed on the floating board, and photovoltaic panels are installed on the support frame. Although this creates a landing spot for birds such as seagulls, the landing of seagulls and other birds also causes the accumulation of garbage and dirt on the surface of the photovoltaic panels due to the droppings and feathers of the seagulls and other birds, as well as the weeds produced by their nesting. If the excessive accumulation of bird droppings and garbage is not cleaned up in time, it will affect the power generation performance of the photovoltaic panels. When laying the offshore photovoltaic equipment, the present invention connects multiple frames 1 with each other using the card slots 27 to form an offshore floating platform, and then the mounting frame 4 is plugged and fixed inside the mounting block 3. At the same time, the photovoltaic panel 7 is installed on the photovoltaic support plate 5 between the mounting frames 4, and the photovoltaic support plate 5 is rotated by toggling, thereby driving the photovoltaic panel 7 to adjust the tilt angle so as to better receive sunlight. When the photovoltaic panel 7 is in operation, the sliding frame 84 outside the fixed sliding column 82 is driven to make reciprocating motion, and the sliding frame 84 drives the cleaning rod 85 to move synchronously, and then the cleaning rod 85 can be used to clean the bird droppings and other dirt on the surface of the photovoltaic panel 7 to prevent the accumulation of bird droppings and other dirt from affecting the power generation efficiency of the photovoltaic panel 7. After the frame 1 is installed, the buoy 11 is pushed by the waves. It floats up and down in the inner cavity of the frame 1, and at the same time, the buoy 11 pulls the third traction rope 20 to expand and contract in the inner cavity of the frame 1, so that the third traction rope 20 pulls the skateboard 19 to move synchronously in the inner cavity of the frame 1. During the reciprocating sliding process of the skateboard 19 in the inner cavity of the frame 1, it squeezes the seawater in the inner cavity of the frame 1 and pushes it outward, so that the seawater forms waves to offset the waves pushed toward the shore, thereby reducing the waves pushed in, so as to reduce the impact of the waves on the frame 1, and thus reduce the swing of the frame 1, avoid the photovoltaic equipment from being subjected to large mechanical stress for a long time, and the occurrence of structural fatigue deformation, and reduce the impact force of the waves, and can also reduce the inclination angle of the swing of the photovoltaic panel 7, thereby ensuring that the photovoltaic panel 7 always maintains a stable state to receive sunlight radiation, increase power generation, and thus solve the above problems.

[0025] like Figure 1 、 Figure 5 and Figure 6 As shown, a first spring 83 is fixedly connected to one side of the sliding frame 84, and the first spring 83 is fixedly connected to the photovoltaic support plate 5. A brush and a scraper are provided on the lower end surface of the cleaning rod 85, which are used to use the brush to scrub the garbage on the surface of the photovoltaic panel 7, and use the scraper to scrape off the residual water stains and sticky bird droppings on the surface of the photovoltaic panel 7.

[0026] like Figure 1 、 Figures 4 to 6As shown, an L-shaped rotating groove 25 is opened inside one end of the mounting frame 4, a second spring 23 is fixedly connected to the inner wall of the L-shaped rotating groove 25, an L-shaped clamping block 24 is fixedly connected to one end of the second spring 23, and a rotating shaft 26 is rotatably connected between the mounting frames 4. The rotating shaft 26 is located outside the inner cavity of the L-shaped rotating groove 25 and is fixedly connected to the ratchet 22, and the L-shaped clamping block 24 is plugged into and engaged with the ratchet 22.

[0027] like Figure 1 、 Figures 4 to 6 As shown, an H-shaped rotating block 21 is fixed to the outside of the rotating shaft 26, and the H-shaped rotating block 21 is fixed to the photovoltaic support plate 5 by bolts. The rotating shaft 26 is used to drive the H-shaped rotating block 21 to rotate, and can drive the photovoltaic support plate 5 to rotate to adjust the tilt angle of the photovoltaic panel 7.

[0028] Specifically, after the photovoltaic panel 7 is installed, the second spring 23 is squeezed by toggling the L-shaped block 24, and then the photovoltaic support plate 5 is rotated, and the photovoltaic support plate 5 drives the H-shaped rotating block 21 to rotate. At the same time, the H-shaped rotating block 21 drives the rotating shaft 26 to rotate, and then drives the ratchet 22 to rotate, so that the photovoltaic support plate 5 drives the photovoltaic panel 7 to adjust the tilt angle, so that the photovoltaic panel 7 can better receive sunlight radiation. After adjusting the angle of the photovoltaic panel 7, the L-shaped block 24 is popped up by the second spring 23, and the L-shaped block 24 is plugged and engaged with the ratchet 22, thereby fixing the rotating shaft 26 and the photovoltaic support plate 5, thereby solving the problem that the existing water photovoltaic equipment usually uses bolts or binding to directly fix the photovoltaic panel and the support frame when installing the photovoltaic panel. This results in the need to disassemble and reinstall the photovoltaic panel and the support frame when adjusting the tilt angle of the photovoltaic panel, which is not only cumbersome to operate but also affects the efficiency of laying and installing the photovoltaic panel.

[0029] like Figure 3 、 Figure 6 and Figure 8 As shown, a winding rack 13 is fixedly received and wound on the outside of the rotating shaft 26, a second traction rope 12 is fixedly received and wound in the middle of the winding rack 13, and one end of the second traction rope 12 is fixedly installed on the buoy 11, and the buoy 11 is used to drive the second traction rope 12 to pull the winding rack 13 to rotate, and a counterweight block 16 is installed in the middle of the lower end of the buoy 11.

[0030] like Figure 3 、 Figure 5 and Figure 6 As shown, two first traction ropes 86 are fixed on both sides of the winding frame 13, a sealing plate 14 is installed on the lower end surface of the photovoltaic support plate 5, and two through openings 15 are provided on the lower end surface of the sealing plate 14. Two limit blocks 87 are provided on one side of the inner wall of the slide groove 81, and one end of the two first traction ropes 86 passes through the through opening 15 and the limit blocks 87 and is fixedly connected to the sliding frame 84.

[0031] Specifically, when cleaning dirt on the surface of the photovoltaic panel, the buoy 11 is moved up and down by utilizing the fluctuation of the waves. When the buoy 11 moves downward, it will pull the second traction rope 12 out of the winding rack 13. At the same time, the second traction rope 12 drives the winding rack 13 to rotate. During the rotation of the winding rack 13, it will drive the first traction rope 86 to reel in. At the same time, the first traction rope 86 pulls the sliding rack 84 to slide outside the fixed sliding column 82, and makes the sliding rack 84 drive the cleaning rod 85 to move synchronously. The lower end surface of the cleaning rod 85 is provided with a brush and a scraper, so that the brush can be used to scrub the garbage on the surface of the photovoltaic panel 7 during the movement of the cleaning rod 85, and the scraper can be used to scrape off the residual water stains and sticky bird droppings on the surface of the photovoltaic panel 7. When the buoy 11 moves upward, the first spring is used to 83 pops up and the sliding frame 84 moves and resets. At the same time, the sliding frame 84 pulls the first traction rope 86 to move and reset, and the first traction rope 86 drives the winding frame 13 to rotate. The winding frame 13 will drive the second traction rope 12 to reel in the process of rotation, thereby solving the problem that after the existing water photovoltaic equipment lays the photovoltaic panels on the sea surface for use, the offshore photovoltaic equipment will attract birds on the seashore to land and roost, which will cause bird droppings to fall on the surface of the photovoltaic panels. If they are not cleaned and accumulated for a long time, it will affect the power generation of the photovoltaic panels. In particular, after the bird droppings are dried in the sun, the bird droppings will stick to the surface of the photovoltaic panels and solidify. It is difficult to clean the dried and solidified bird droppings with a broom alone, which not only affects the power generation of the photovoltaic panels, but also reduces the life of the photovoltaic panels.

[0032] Example 2: Figure 2 、 Figure 7 and Figure 8 As shown, wave spraying ports 9 are provided on both sides of the frame 1, a wave-making groove 17 is provided in one side of the frame 1, two slides 19 are slidably connected in the inner cavity of the wave-making groove 17, a second tension spring 18 is fixed between the two slides 19, a water spraying port 10 is provided in the middle of the wave-making groove 17, and the slide 19 is driven to reciprocate in the inner cavity of the wave-making groove 17 for cyclically pumping and discharging seawater to create waves.

[0033] Specifically, after the photovoltaic panels 7 are laid, the buoys 11 are pushed up and down by the waves. During the upward movement of the buoys 11, the second tension spring 18 in the inner cavity of the wave-making trough 17 will pull the slide plates 19 to move closer to each other. At the same time, the slide plates 19 squeeze the seawater between them and spray it out through the water nozzle 10 to create water waves. As the buoys 11 move downward with the waves and the counterweight 16, the third traction rope 20 will be driven to pull the slide plates 19 away from each other. At the same time, the slide plates 19 squeeze the seawater on both sides of the inner cavity of the wave-making trough 17 and spray it out through the wave nozzle 9 to create water waves. The water waves sprayed by the water nozzle 10 and the wave nozzle 9 will offset the waves pushed toward the coast, thereby The amplitude of the waves is reduced, and the waves are prevented from directly impacting the frame 1, causing the photovoltaic equipment to swing greatly after the splicing is completed. This solves the problem that after the existing water photovoltaic equipment is laid on the sea surface, it is difficult to reduce the amplitude of the waves pushed toward the coast, resulting in the waves directly impacting the laid photovoltaic equipment, causing the photovoltaic equipment to swing greatly with the waves. The photovoltaic equipment is subjected to the mechanical stress caused by this large-scale swing for a long time, which can easily lead to damage such as structural fatigue deformation of the photovoltaic equipment. In addition, the swing of the photovoltaic equipment will also affect the inclination angle of the photovoltaic panel, resulting in the photovoltaic panel being unable to always maintain a stable state to receive sunlight radiation, thereby greatly reducing the power generation of the photovoltaic equipment.

[0034] like Figure 2 、 Figure 7 and Figure 8 As shown, a spray assembly 6 is provided on one side of the frame 1, and the spray assembly 6 includes a sealed chamber 61 opened in one side of the frame 1, two pistons 64 are slidably connected in the sealed chamber 61, and a third traction rope 20 is fixed to one side of the two pistons 64, and one end of the third traction rope 20 passes through the frame 1 and is fixed to the float 11.

[0035] like Figure 1 、 Figure 7 and Figure 8 As shown, a first tension spring 63 is fixed between the pistons 64, a water extraction port 62 is provided at the bottom of the inner cavity of the sealed cavity 61, and a one-way valve is provided in the inner cavity of the water extraction port 62. The one-way valve can only be flipped open into the sealed cavity 61, and is used to drive the piston 64 to perform reciprocating motion, so that the one-way valve can be cyclically opened to extract seawater into the sealed cavity 61.

[0036] like Figure 2 、 Figure 7 and Figure 8As shown, a folding tube 65 is fixedly connected to one side of the upper end of the frame 1, and the folding tube 65 is connected to the sealed cavity 61, one end of the folding tube 65 is fixedly connected to a T-shaped spraying tube 66, and the T-shaped spraying tube 66 is fixedly installed on the photovoltaic support plate 5, and a one-way valve is provided at the fixed connection between the T-shaped spraying tube 66 and the folding tube 65, and the one-way valve can only be flipped open toward the inner cavity of the T-shaped spraying tube 66.

[0037] Specifically, when the buoy 11 moves up and down with the waves, the buoy 11 will drive the third traction rope 20 to move synchronously. At the same time, the third traction rope 20 pulls the piston 64 to do reciprocating motion in the sealed chamber 61. When the piston 64 moves closer to each other using the first tension spring 63, the piston 64 squeezes the seawater in the sealed chamber 61 and transports the seawater into the folded tube 65 under pressure, and squeezes open the one-way valve in the inner cavity of the T-shaped spray pipe 66, and then sprays it through the T-shaped spray pipe 66 to wash the surface of the photovoltaic panel 7. The buoy 11 pulls When the third traction rope 20 drives the pistons 64 to move away from each other, the pistons 64 will pump the sealed chamber 61 to form a negative pressure to open the one-way valve in the inner cavity of the water pumping port 62, and at the same time, draw seawater into the sealed chamber 61 through the water pumping port 62. During the movement of the pistons 64 away from each other, the seawater on both sides of the sealed chamber 61 will be squeezed and sprayed out through the wave spraying port 9 to create waves, thereby forming a relative force with the waves sprayed out from the wave spraying port 9 on the other side of the frame 1, thereby reducing the thrust generated by the seawater sprayed out from the wave spraying ports 9 on both sides of the frame 1 to create waves, so as to ensure that the frame 1. The stability of the sea surface, and the seawater sprayed onto the surface of the photovoltaic panel 7 washes and softens dirt such as bird droppings, so that the cleaning rod 85 can better scrape and clean it. At the same time, the cleaning rod 85 scrapes the seawater remaining on the surface of the photovoltaic panel 7 to prevent the seawater from evaporating and forming crystals on the surface of the photovoltaic panel 7, thereby affecting the power generation of the photovoltaic panel 7. This solves the problem that when the existing water photovoltaic equipment is laid out on the sea surface and used, a large number of birds such as seagulls will stay or perch on the photovoltaic equipment, which inevitably causes birds to defecate on the surface of the photovoltaic panel. After being exposed to the sun and dried, the bird droppings will stick to the surface of the photovoltaic panel and solidify. It is difficult to clean the dried and solidified bird droppings with a broom alone. If the seawater is used for cleaning, if the seawater remaining on the surface of the photovoltaic panel is not scrubbed or scraped clean after cleaning, the seawater will crystallize after being exposed to the sun. The crystals produced by the seawater will form a white crystalline layer on the surface of the photovoltaic panel, which will not only affect the power generation performance of the photovoltaic panel, but also cause erosion to the photovoltaic panel, resulting in damage to the photovoltaic panel, greatly reducing the service life of the photovoltaic panel.

[0038] Working principle: after the photovoltaic panel 7 is installed, the second spring 23 is squeezed by toggling the L-shaped block 24, and then the photovoltaic support plate 5 is rotated, and the photovoltaic support plate 5 drives the H-shaped rotating block 21 to rotate. At the same time, the H-shaped rotating block 21 drives the rotating shaft 26 to rotate, and then drives the ratchet 22 to rotate, so that the photovoltaic support plate 5 drives the photovoltaic panel 7 to adjust the tilt angle, so that the photovoltaic panel 7 can better receive sunlight radiation. After the angle of the photovoltaic panel 7 is adjusted, the L-shaped block 24 is popped up by the second spring 23, and the L-shaped block 24 is plugged and engaged with the ratchet 22, thereby fixing the rotating shaft 26 and the photovoltaic support plate 5. When cleaning the dirt on the surface of the photovoltaic panel, the buoy 11 is moved up and down by the fluctuation of the waves. When the buoy 11 moves downward, it pulls the second traction rope 12 out of the winding rack 13. At the same time, the second traction rope 12 drives the winding rack 13 to rotate. During the rotation of the winding rack 13, it drives the first traction rope 86 to reel in. At the same time, the first traction rope 86 pulls the sliding rack 84 to slide outside the fixed sliding column 82, and the sliding rack 84 drives the cleaning rod 85 to move synchronously. The lower end surface of the cleaning rod 85 is provided with a brush and The scraper can use the brush to scrub the garbage on the surface of the photovoltaic panel 7 during the movement of the cleaning rod 85, and use the scraper to scrape off the residual water stains and sticky bird droppings on the surface of the photovoltaic panel 7. When the float 11 moves upward, the first spring 83 is used to bounce the sliding frame 84 to move and reset. At the same time, the sliding frame 84 pulls the first traction rope 86 to move and reset, and the first traction rope 86 drives the winding frame 13 to rotate. The winding frame 13 will drive the second traction rope 12 to reel in during the rotation process, thereby achieving the cleaning work on the surface of the photovoltaic panel; After the photovoltaic panels 7 are laid, the buoys 11 are pushed up and down by the waves. During the upward movement of the buoys 11, the second tension spring 18 in the inner cavity of the wave-making trough 17 will pull the slide plates 19 closer to each other. At the same time, the sea water between the slide plates 19 is squeezed and ejected through the water nozzles 10 to create water waves. As the buoys 11 move downward with the waves and the counterweight block 16, the third traction rope 20 will drive the slide plates 19 to move away from each other. At the same time, the slide plates 19 squeeze the sea water on both sides of the inner cavity of the wave-making trough 17 and eject the sea water through the wave nozzles 9 to create water waves. The water waves ejected from the water nozzles 10 and the wave nozzles 9 will offset the waves pushed toward the coast, thereby reducing the amplitude of the waves and preventing the waves from directly impacting the frame 1, causing the photovoltaic equipment to swing significantly after the splicing is completed, thereby improving the service life of the photovoltaic equipment structure.
