[0026] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0027] Combine the following Figure 1-Figure 5 A floating offshore photovoltaic platform capable of cleaning photovoltaic modules according to an embodiment of the present invention is described.

[0028] The floating offshore photovoltaic platform capable of cleaning photovoltaic modules of the embodiment of the present invention comprises a platform body 1, a vertical rod 2, a cleaning rod 3 and a driving device. The platform body 1 comprises an upper frame 11, the projected outer contour of the upper frame 11 in the height direction is a regular hexagon, and the upper surface of the upper frame 11 is paved with photovoltaic modules 18. The vertical rod 2 is pivotally mounted at least partially at the corners of the upper frame 11. The number of cleaning rods 3 is equal to that of the vertical rods 2 and corresponds one to one. The first end of the cleaning rod 3 is pivotally connected to the corresponding vertical rod 2. A water storage chamber is provided in the cleaning rod 3. The lower surface of the cleaning rod 3 is provided with a plurality of nozzles connected to the water storage chamber, and the lower surface of the cleaning rod 3 is provided with a brush 31. The driving device is mounted on the upper frame 11 and is transmission-connected to the vertical rod 2.

[0029] According to the floating offshore photovoltaic platform capable of cleaning photovoltaic modules according to the embodiment of the present invention, a vertical rod 2 is rotatably installed at the corner position of the upper frame 11, and a cleaning rod 3 is provided to be connected to the vertical rod 2, so that the cleaning rod 3 can rotate around the central axis of the vertical rod 2 to rotate above the photovoltaic module 18. When the photovoltaic module 18 needs to be cleaned, water is supplied to the water storage chamber in the cleaning rod 3 and pressurized to spray high-pressure water flow at the nozzle, and the driving device drives the cleaning rod 3 to rotate above the photovoltaic module 18 through the vertical rod 2. While the high-pressure water flow flushes the photovoltaic module 18, the brush 31 on the cleaning rod 3 also brushes the upper surface of the photovoltaic module 18, accelerates the cleaning of the dirt on the upper surface of the photovoltaic module 18, and improves the cleaning efficiency of the photovoltaic module 18. Moreover, the cleaning of the photovoltaic module 18 by the cleaning rod 3 is basically not affected by the complex external environment, thereby effectively improving the reliability of the cleaning effect of the cleaning rod 3 on the photovoltaic module 18.

[0030] Specifically, there are multiple cleaning rods 3, each cleaning rod 3 corresponds to cleaning a different area of ​​the photovoltaic module 18, thereby avoiding interference between the cleaning rod 3 and the electric control system 19 located at the center of the upper frame 11, while also ensuring that the cleaning rod 3 can achieve cleaning of all areas of the photovoltaic module 18.

[0031] In some embodiments, Figure 3-Figure 5 As shown, there are six vertical rods 2, and each corner of the upper frame 11 is rotatably mounted with a vertical rod 2. The driving device includes six motors 4 corresponding to the vertical rods 2, which are installed below the upper frame 11 and are drivingly connected to the corresponding vertical rods 2.

[0032] Therefore, the six cleaning rods 3 correspond to six areas of the photovoltaic module 18, and each cleaning rod 3 swings back and forth within a range of 60° to achieve cleaning of the corresponding area of ​​the photovoltaic module 18. This arrangement greatly improves the cleaning efficiency of the photovoltaic module 18. Moreover, after the cleaning of the photovoltaic module 18 is completed, the six cleaning rods 3 are respectively stationary at the six edges of the upper frame 11 to act as a barrier, thereby effectively ensuring the working safety of the staff on the upper frame 11.

[0033] Specifically, the length of the cleaning rod 3 is slightly smaller than the side length of the projection of the upper frame 11, one end of the cleaning rod 3 is connected to the upper end of the corresponding vertical rod 2, the motor 4 is installed below the upper frame 11, and the motor shaft of the motor 4 passes through the upper frame 11 and is coaxially connected to the lower end of the vertical rod 2.

[0034] In some embodiments, Figure 3-Figure 5 As shown, a stopper rod 5 extends upward from the upper surface of the upper frame 11 and is located at the outer edge of the photovoltaic assembly 18. The stopper rod 5 can abut against the outer side surface of the cleaning rod 3 to prevent the cleaning rod 3 from protruding from the outer peripheral surface of the upper frame 11 in the horizontal direction.

[0035] After the cleaning rod 3 finishes cleaning the photovoltaic assembly 18, the cleaning rod 3 is reset to the outer side of the photovoltaic assembly 18 to prevent the cleaning rod 3 from blocking the sunlight and affecting the power generation efficiency of the photovoltaic assembly 18. At this time, the end of the cleaning rod 3 away from the vertical rod 2 abuts against the stop rod 5, thereby preventing the cleaning rod 3 from rotating away from the photovoltaic assembly 18, while also ensuring that it has a reliable enclosure function.

[0036] Specifically, there are six gear bars 5 corresponding to the cleaning bars 3 one by one. The gear bars 5 extend along the height direction and are welded to the edge of the upper frame 11 .

[0037] In some embodiments, the outer edge of the upper frame 11 is extended upward to be provided with a fence, which is located on the outer peripheral side of the vertical rod 2 and the cleaning rod 3. The fence extends around the outer edge of the upper frame 11 and is connected end to end.

[0038] The fence itself realizes the enclosure function to ensure the working safety of the staff on the upper frame 11 . At the same time, the fence can also prevent the cleaning rod 3 from rotating in a direction away from the photovoltaic component 18 and affecting the cleaning efficiency of the photovoltaic component 18 .

[0039] In some embodiments, Figure 3 and Figure 4 As shown, the brushes 31 have multiple clusters and are arranged in sequence along the length direction of the cleaning rod 3, wherein the brushes 31 and the nozzles are arranged at intervals along the width direction of the cleaning rod 3, or, the number of clusters of the brushes 31 corresponds to the nozzles one by one, and each cluster of the brushes 31 is arranged around the corresponding nozzle.

[0040] The above arrangement enables the brush 31 and the nozzle to repeatedly perform brushing and flushing operations on the photovoltaic module 18 when the cleaning rod 3 swings back and forth around the vertical rod 2, so as to better achieve the cleaning efficiency of the photovoltaic module 18.

[0041] Specifically, the plurality of nozzles are arranged at equal intervals along the length direction of the cleaning rod 3 , and the distance between two nozzles located at the edge is substantially equal to the length of the brush 31 .

[0042] In some embodiments, Figure 1 and Figure 2 As shown, the platform body 1 also includes a lower frame 12, columns, a desalination device, a water pump and a water pipe. The vertical rod 2 is connected between the lower frame 12 and the upper frame 11, and a floating body 17 is provided on the lower frame 12. The desalination device is installed on the lower frame 12, and the desalination device is connected to each cleaning rod 3 through a water pipe, and the water pump is installed on the water pipe.

[0043] The seawater desalination device is used to supply fresh water to the water storage chamber in the cleaning rod 3 to ensure that the cleaning rod 3 uses fresh water to complete the flushing of the photovoltaic component 18. Compared with using seawater to flush the photovoltaic component 18, it is effective to avoid the flushing water droplets attached to the photovoltaic component 18 after the photovoltaic component 18 is flushed. The rinsing water droplets attached to the photovoltaic component 18 will be dried and salt will be generated, thereby affecting the power generation efficiency of the photovoltaic component 18.

[0044] Specifically, the water pump installed on the water pipe is used to pressurize the water storage chamber in the cleaning rod 3 to ensure that the nozzle sprays high-pressure water flow to achieve effective flushing of the photovoltaic module 18.

[0045] In some embodiments, the inner cavity of at least part of the column forms a fresh water cavity, the seawater desalination device is connected to the fresh water cavity, and the water pipe is connected to the fresh water cavity.

[0046] The fresh water chamber is provided to facilitate the storage of fresh water generated by the desalination device, ensuring that there is sufficient fresh water when cleaning the photovoltaic module 18 without being affected by the power of the desalination device. A small-sized and lower-cost desalination device can be used, and the desalination device continues to work when the photovoltaic module 18 is not being cleaned to complete the storage of fresh water.

[0047] Specifically, there are multiple columns including a central column 13, an intermediate column 14 and an edge column 15, there are multiple intermediate columns 14 and are arranged at intervals along the circumference of the central column 13, and there are multiple edge columns 15 and are arranged at intervals along the circumference of the central column 13. The inner cavities of the six edge columns 15 adjacent to the vertical rods 2 form a fresh water cavity, and each fresh water cavity is connected to the water storage cavity of the adjacent cleaning rod 3 through a corresponding water pipe. In this case, the length of the water pipe is shorter and the installation cost is lower.

[0048] In some embodiments, the water pipe is a hose, and the water pipe, the water pump and the cleaning rod 3 correspond to each other one by one. The water pipe connects the fresh water cavity and the corresponding cleaning rod 3, and the water pump is installed on the corresponding water pipe.

[0049] By installing a water pump on each water pipe, the spraying condition of each cleaning rod 3 can be set relatively independently. For example, if there is too much salt and / or bird droppings attached to a certain area through video observation, the corresponding water pump can be controlled to work longer than other water pumps to achieve a longer flushing time for the area, thereby ensuring the same speed of cleaning efficiency for the photovoltaic components 18 and effectively reducing the cleaning cost.

[0050] Specifically, a through hole is provided in the upper frame 11 adjacent to the vertical rod 2 , one end of the water pipe is located below the upper frame 11 and communicates with the fresh water chamber, and the other end of the water pipe passes through the through hole and communicates with the water storage chamber of the corresponding cleaning rod 3 .

[0051] In some embodiments, the floating offshore photovoltaic platform capable of cleaning photovoltaic modules also includes a liquid storage box, an infusion tube and a control valve. The liquid storage box is used to store a chemical solution capable of cleaning bird droppings and salt stains. The infusion tube connects the liquid storage box and the water pipe, and the control valve is installed on the infusion tube.

[0052] That is, a high-concentration chemical solution can be pre-stored in the liquid storage box. After the photovoltaic module 18 is cleaned with fresh water, if it is found that there are bird droppings and / or salt residues in some areas on the photovoltaic module 18 that cannot be cleaned, the water pump and the control valve can be started, and the fresh water and the high-concentration chemical solution will merge in the water pipe and flow into the water storage chamber together, thereby forming a chemical solution of appropriate concentration, which is convenient for reliable and rapid cleaning of bird droppings and / or salt stains.

[0053] In some embodiments, an electric control system 19 is provided in the middle of the upper frame 11 , and the floating offshore photovoltaic platform capable of cleaning photovoltaic components further includes a camera module, which is installed in the electric control system 19 and is used to monitor the photovoltaic components 18 .

[0054] When the cleaning rod 3 is cleaning the photovoltaic module 18, the camera module can take a real-time photo of the photovoltaic module 18, and mark the difficult-to-clean position, so that the difficult-to-clean position can be reliably cleaned by adding chemical solution or increasing the operation time. At the same time, the staff can also observe the cleanliness of the upper surface of the photovoltaic module 18 from time to time through the camera module to determine whether to perform the cleaning operation.

[0055] Specifically, the camera module is disposed above the electric control system 19 to complete 360° no-dead-angle shooting of the surrounding photovoltaic components 18 .
