Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power stations, and in particular to a floating photovoltaic power station and a use method thereof. Background Art

[0002] In the early stages of the development of photovoltaic technology, photovoltaic power stations were mainly ground-mounted, which required a large amount of land area. In areas with tight land resources, finding a suitable installation site became a problem. With the increase in demand for renewable energy and thinking about the use of land resources, people began to consider using water surfaces to install photovoltaic power stations. The water area is vast, especially some reservoirs, lakes, ponds, etc. These water surfaces provide new possibilities for photovoltaic power stations in terms of space utilization. As a result, the concept of floating photovoltaic power stations gradually emerged. The initial idea was to simply place photovoltaic panels on a floating device so that they could float stably on the water surface, while using the space on the water surface for photovoltaic power generation.

[0003] However, the existing floating photovoltaic power stations cannot withstand harsh environments when in use. For example, when it snows or hail, the surface of the photovoltaic panels is easily hit by hail, causing depressions on the surface of the photovoltaic panels. The surface of the photovoltaic panels will also be covered with snow, making it impossible to work normally. If it rains heavily, rainwater forms a water film on the surface of the photovoltaic panels, which will reflect and refract sunlight, reducing the actual amount of sunlight energy absorbed by the photovoltaic panels. After the rain stops, the rainwater remaining on the surface of the photovoltaic panels needs a lot of time to evaporate before the efficiency of the photovoltaic panels can be maximized. Summary of the invention

[0004] In view of the fact that the above-mentioned floating photovoltaic power station cannot withstand harsh environments when in use, for example, when it snows or hails, the surface of the photovoltaic panel is easily hit by hail, causing depressions on the surface of the photovoltaic panel, and the surface of the photovoltaic panel will also be covered with snow, making it impossible to work normally. If it is heavy rainfall, rainwater forms a water film on the surface of the photovoltaic panel, which will reflect and refract sunlight, reducing the actual amount of sunlight energy absorbed by the photovoltaic panel. After the rain stops, the rainwater remaining on the surface of the photovoltaic panel needs a lot of time to evaporate before the efficiency of the photovoltaic panel can reach the highest level. The present invention is proposed.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a floating photovoltaic power station, comprising: a longitudinal connecting rod and a transverse connecting rod, a pair of longitudinal connecting rods are provided with a plurality of transverse connecting rods at the lower surface, cylindrical buoys are provided below the transverse connecting rods, circular ring mounting sleeves are provided at the arc surface outside the plurality of cylindrical buoys, connecting plates are also provided at the arc surface outside the circular ring mounting sleeves, rectangular aisle plates are also installed at the inner ring of the transverse connecting rods, and rectangular support rods are provided at the inner ring of the longitudinal connecting rods;

[0006] L-shaped positioning plates are provided on the vertical surfaces on both sides of the rectangular support rod, a U-shaped adjustment plate is also provided at the end point of the upper end of the rectangular support rod, and a docking rod is also provided at the inclined surface of the U-shaped adjustment plate, and a rectangular mounting block is also provided on the upper surface of a pair of docking rods, a photovoltaic panel is installed on the upper surface of the rectangular mounting block, and an I-shaped mounting block is also provided on the upper surface of the docking rod, and an L-shaped limiting plate is provided on the upper surface of the I-shaped mounting block.

[0007] As a preferred solution of a floating photovoltaic power station described in the present invention, a pair of L-shaped limit plates are both connected through the same threaded conveying rod, one of the end points of the threaded conveying rod is also provided with a first driving motor, a pair of threaded conveying rods are both provided with a transmission wheel penetrated through the rod body, a pair of the transmission wheels are both connected to the same belt, and a rectangular magnet is also provided on the upper surface of the I-shaped mounting block.

[0008] As a preferred solution of a floating photovoltaic power station described in the present invention, a pair of threaded conveying rods are connected to the same cleaning structure on their rod bodies, and the cleaning structure includes a trapezoidal moving block and a rectangular mounting plate, and the trapezoidal moving block is mounted on the rod body of the rectangular mounting plate.

[0009] As a preferred solution of a floating photovoltaic power station described in the present invention, the relative vertical surfaces of a pair of trapezoidal moving blocks are connected to a rectangular mounting plate, an arc-shaped scraper is penetrated on the rectangular mounting plate, a rectangular sleeve is further provided at the end point of the arc-shaped scraper away from the trapezoidal moving block, and a scraper is further installed on the lower surface of the rectangular sleeve, rectangular loading rods are provided on the vertical surfaces of the pair of trapezoidal moving blocks, rectangular mounting bars are further provided between the rectangular loading rods, and a convex lens is penetrated on the upper surface of the rectangular mounting bar.

[0010] As a preferred solution of the floating photovoltaic power station described in the present invention, a docking strip is provided through the upper surface of the rectangular mounting plate, a rectangular mounting sleeve is provided on the lower surface of the docking strip, and a soft brush is provided on the lower surface of the rectangular mounting sleeve.

[0011] As a preferred solution of a floating photovoltaic power station described in the present invention, wherein: an I-shaped mounting block away from the first drive motor has a rectangular storage box on its upper surface, a pair of item sensors are also provided on the vertical surface of the outside of the rectangular storage box, a pair of winding rollers are also provided inside the rectangular storage box, the pair of winding rollers are respectively wrapped with an insulation layer and a protective layer, and rectangular baffles are provided at the end points of the insulation layer and the protective layer, a pair of U-shaped hooks are provided on the vertical surfaces of the rectangular baffles, and rotating rods are provided on the circular surfaces of both ends of the pair of winding rollers, and the circular surface of one of the rotating rods is connected to the output end of the second drive motor.

[0012] The present invention also provides an on-site use method of a floating photovoltaic power station, the purpose of which is that: when the floating photovoltaic power station is in use, it cannot withstand a harsh environment. For example, when it snows or hails, the surface of the photovoltaic panel is easily hit by hail, causing the surface of the photovoltaic panel to become concave, and the surface of the photovoltaic panel will also be covered with snow, thereby being unable to work normally. If it rains heavily, rainwater forms a water film on the surface of the photovoltaic panel, which will reflect and refract sunlight.

[0013] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a floating photovoltaic power station and a method for using the same, comprising the following steps: before starting the first driving motor, first confirm the current working environment of the photovoltaic panel. If it is below zero in winter, because a rectangular lifting groove is provided on the vertical surface of the trapezoidal moving block, and a water storage bag is provided on the bottom surface of the rectangular lifting groove, the water inside the water storage bag will freeze. Because the volume of water will increase after freezing, the water storage bag will push the rectangular lifting block to rise;

[0014] After that, just start the first drive motor directly, and then the threaded conveying rod will rotate. Because a transmission wheel is also provided on the rod body of the threaded conveying rod, when the first drive motor is started, a pair of trapezoidal moving blocks will move. During the movement of the trapezoidal moving blocks, a soft brush is provided on the lower surface of the rectangular sleeve to pre-clean the photovoltaic panel. Because the inclined surface of the trapezoidal plate is facing the U-shaped hook, after the trapezoidal plate contacts the U-shaped hook, the trapezoidal moving block will continue to move. During the movement of the trapezoidal plate, the trapezoidal plate will retreat due to the influence of the thrust, and enter the inner ring of the U-shaped hook. After there is no resistance, the memory spring will bounce the trapezoidal piece back. At this time, the item sensor at the top will send a wireless signal after detecting the trapezoidal piece, and the wireless signal will be received by the second drive motor above.

[0015] Eventually, the second drive motor will rotate, and the first drive motor will rotate in the opposite direction, causing the trapezoidal moving block to reset. At this time, the trapezoidal plate will pull the U-shaped hook, and eventually the top insulation layer will be pulled out. After the object sensor finds that the trapezoidal piece has disappeared, it will delay the signal transmission for 45-60s, which is enough time for the insulation layer to be laid.

[0016] If the working environment of the photovoltaic panel is heavy rain at that time, the drive motor is started directly. Because the temperature of the external environment is above degrees Celsius, the water storage bag will not be expanded, so the rectangular lifting block will not rise, and the subsequent steps can be operated according to the above-mentioned operation below 0 degrees Celsius. The subsequent steps are the same, because heavy rain is sudden, and personnel operation and reaction take time, and there are already water droplets on the photovoltaic panel at this time. After the rain is completed, because the protective layer and the thermal insulation layer are elastic materials, and the trapezoidal moving block is still some distance away from the rectangular magnet, the first motor will move the trapezoidal movement in the direction of the transmission wheel for a small distance. When the trapezoidal moving block and the rectangular magnet are in the same horizontal plane, the circular iron sheet will be moved by the attraction of the rectangular magnet, so that the trapezoidal sheet will be detached from the range of the U-shaped hook, and then the staff will remotely control it to make the second drive motor drive the winding roller to rotate and retract the protective layer. Then let the soft brush clean most of the water droplets on the photovoltaic panel, and the convex lens will evaporate a small amount of water droplets on the photovoltaic panel during the movement.

[0017] If the photovoltaic panel only needs to be cleaned, the first drive motor can be directly started, and the trapezoidal moving block will move. During the movement, the soft brush arranged on the lower surface of the rectangular sleeve will clean the dust on the photovoltaic panel, and the harder dust particles on the photovoltaic panel will be hung down by the scraper arranged at the end point of the arc scraper away from the trapezoidal moving block.

[0018] Beneficial effects of the present invention:

[0019] 1. The equipment is equipped with a device to protect the photovoltaic panels. When encountering harsh environments, the insulation layer and protective layer inside the rectangular storage box will be pulled out to cover the surface of the photovoltaic panels, thereby protecting and insulating the photovoltaic panels, ensuring that the photovoltaic panels will not be affected by the external environment, so that they can be better protected and the service life of the photovoltaic panels can be extended.

[0020] 2. The device also has a structure that speeds up the cleaning of rainwater on the surface of the photovoltaic panels. After most of the rainwater is removed, a small part of the rainwater will be evaporated by the sunlight gathered by the convex lens, thereby speeding up the evaporation of water and the cleaning effect. In addition, when encountering conditions such as icing, the convex lens can also melt the ice, ensuring that the photovoltaic panels can quickly reach the highest efficiency.

[0021] 3. The device is also equipped with a cleaning structure. The photovoltaic panels floating on the water are often affected by bird droppings and dust particles. The cleaning structure of the device can effectively clean the dust and bird excrement accumulated on the photovoltaic panels to ensure that the photovoltaic panels will not be eroded and affected by the droppings.

[0041] When in use, a floating photovoltaic power station and a method for using the same include the following steps: before starting the first drive motor, first confirm the current working environment of the photovoltaic panel. If it is below zero in winter, because a rectangular lifting groove is provided on the vertical surface of the trapezoidal moving block, and a water storage bag is provided on the bottom surface of the rectangular lifting groove, the water inside the water storage bag will freeze. Because the volume of water will increase after freezing, the water storage bag will push the rectangular lifting block to rise;

[0042] After that, just start the first drive motor directly, and then the threaded conveying rod will rotate. Because a transmission wheel is also provided on the rod body of the threaded conveying rod, when the first drive motor is started, a pair of trapezoidal moving blocks will move. During the movement of the trapezoidal moving blocks, a soft brush is provided on the lower surface of the rectangular sleeve to pre-clean the photovoltaic panel. Because the inclined surface of the trapezoidal plate is facing the U-shaped hook, after the trapezoidal plate contacts the U-shaped hook, the trapezoidal moving block will continue to move. During the movement of the trapezoidal plate, the trapezoidal plate will retreat due to the influence of the thrust, and enter the inner ring of the U-shaped hook. After there is no resistance, the memory spring will bounce the trapezoidal piece back. At this time, the item sensor at the top will send a wireless signal after detecting the trapezoidal piece, and the wireless signal will be received by the second drive motor above.

[0043] Eventually, the second drive motor will rotate, and the first drive motor will rotate in the opposite direction, causing the trapezoidal moving block to reset. At this time, the trapezoidal plate will pull the U-shaped hook, and eventually the top insulation layer will be pulled out. After the object sensor finds that the trapezoidal piece has disappeared, it will delay the signal transmission for 45-60s, which is enough time for the insulation layer to be laid.

[0044] Example 2

[0047] When in use, if the working environment of the photovoltaic panel 10 is heavy rainfall, the drive motor 14 is directly started. Because the temperature of the external environment is above 0 degrees Celsius, the water storage bag 35 will not be expanded, so the rectangular lifting block 37 will not rise. The subsequent steps can be operated according to the above-mentioned 0 degrees Celsius. The subsequent steps are the same. Because heavy rainfall is sudden, personnel operation and reaction take time. At this time, there are already water droplets on the photovoltaic panel 10. After the rainfall is completed, because the protective layer and the thermal insulation layer are elastic materials, and at this time the trapezoidal moving block 19 is still some distance away from the rectangular magnet 17, the first electric The machine 14 will move the trapezoidal moving block 19 a short distance toward the direction of the transmission wheel 15. When the trapezoidal moving block 19 is at the same horizontal plane as the rectangular magnet 17, the circular iron sheet 39 will be moved by the attraction of the rectangular magnet 17, so that the trapezoidal sheet 40 will be separated from the range of the U-shaped hook 31. After that, the staff will remotely control the second drive motor 33 to drive the winding roller 29 to rotate and retract the protective layer. After that, the soft brush 26 can clean most of the water droplets on the photovoltaic panel 10, and the convex lens 24 will evaporate a small amount of water droplets on the photovoltaic panel 10 during the movement.

A floating photovoltaic power station as claimed in any one of claims 1 to 7, comprising the following method of use: before starting the first drive motor (14), first confirm the current working environment of the photovoltaic panel (10). If it is below zero in winter, because a rectangular lifting groove (34) is provided on the vertical surface of the trapezoidal moving block (19), and a water storage bag (35) is provided on the bottom surface of the rectangular lifting groove (34), the water inside the water storage bag (35) will freeze. Because the volume of water will increase after freezing, the water storage bag (35) will push the rectangular lifting block (37) to rise; After that, the first driving motor (14) can be directly started, and then the threaded conveying rod (13) will rotate. Because the rod body of the threaded conveying rod (13) is also provided with a transmission wheel (15), when the first driving motor (14) is started, a pair of trapezoidal moving blocks (20) will move. During the movement of the trapezoidal moving blocks (20), a soft brush (26) is provided on the lower surface of the rectangular sleeve (25) to pre-clean the photovoltaic panel (10). Because the inclined surface of the trapezoidal plate (40) is facing the U-shaped hook (31), the trapezoidal plate (40) is provided with a soft brush (26). ) contacts the U-shaped hook (21), the trapezoidal moving block (19) will continue to move.

After there is no resistance, the memory spring (38) will bounce the trapezoidal plate (40) back.

If the working environment of the photovoltaic panel (10) is heavy rainfall at that time, the driving motor (14) is directly started. Because the temperature of the external environment is higher than (0) degrees Celsius, the water storage bag (35) will not be expanded, so the rectangular lifting block (37) will not rise. The subsequent steps can be operated according to the above-mentioned operation below 0 degrees Celsius. The subsequent steps are the same. Because heavy rainfall is sudden, it takes time for personnel to operate and react. At this time, there are already water droplets on the photovoltaic panel (10). After the rainfall is completed, because the protective layer and the thermal insulation layer are made of elastic materials, and at this time the trapezoidal moving block (19) is still some distance away from the rectangular magnet (17), the first motor (14) will bring the ladder The trapezoidal moving block (19) moves a short distance in the direction of the driving wheel (15). When the trapezoidal moving block (19) and the rectangular magnet (17) are at the same horizontal plane, the circular iron sheet (39) will be moved by the attraction of the rectangular magnet (17), so that the trapezoidal sheet (40) is separated from the range of the U-shaped hook (31). Then, through remote control by the staff, the second driving motor (33) drives the winding roller (29) to rotate and the protective layer is retracted. Then, the soft brush (26) can be used to clean most of the water droplets on the photovoltaic panel (10), and the convex lens (24) will evaporate a small amount of water droplets on the photovoltaic panel (10) during the movement. If the photovoltaic panel (10) only needs to be cleaned, the first drive motor (14) can be directly started, and the trapezoidal moving block (19) will move. During the movement, the soft brush (26) arranged on the lower surface of the rectangular sleeve (25) will clean the dust on the photovoltaic panel (10), and the harder dust particles on the photovoltaic panel (10) will be hung off by the scraper arranged at the end point of the arc scraper (21) away from the trapezoidal moving block (19).
