DETAILED DESCRIPTION

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0030] In the related art, most photovoltaic power stations are equipped with cleaning systems to clean the photovoltaic panels during operation and maintenance, preventing excessive dust accumulation on the panels and affecting the system's power generation, thereby ensuring stable operation of the photovoltaic power station. However, the cleaning system requires the installation of a large number of pipes within the photovoltaic power station, which can easily interfere with the installation and routing of cables within the photovoltaic power station, resulting in a cumbersome and costly overall construction process for the photovoltaic power station. To address the above issues, the present application proposes a frame 10.

[0031] See also Figures 1 to 6 In one embodiment of the present application, the frame 10 includes a frame body 11 and a flow pipe 13. The frame body 11 encloses a fixed cavity, which is used to install and fix the photovoltaic panel 30. A flow space 111 is provided in the frame body 11. The frame body 11 is provided with a water outlet structure 113 connected to the flow space 111. The water outlet structure 113 is used to spray water to the photovoltaic panel 30; the flow pipe 13 includes a first pipe 131 and a second pipe 133. The first pipe 131 and the second pipe 133 are respectively connected to the frame body 11 and respectively connected to the flow space 111.

[0032] It is understood that the photovoltaic power station can use mounting components such as pressure blocks, clamps, or bolt mounts to connect and fix the frame 10 of the photovoltaic system 100 to the frame of the photovoltaic support, so that the photovoltaic system 100 can be stably assembled on the photovoltaic support. Specifically, the photovoltaic system 100 can use the frame 10 to surround and fix the photovoltaic panel 30, which can be made of photovoltaic materials. The frame 10 can provide a certain degree of protection for the photovoltaic panel 30, preventing the photovoltaic panel 30 from being broken by external forces, so that the photovoltaic panel 30 can be stably mounted on the photovoltaic support to absorb and convert light energy, thereby ensuring the stable operation of the photovoltaic power station.

[0033] In this embodiment, the frame 11 of the frame 10 can be an annular structure or a groove. In this case, the frame 11 can be enclosed to form an open fixed cavity, so that the photovoltaic system 100 can accommodate and install the photovoltaic panel 30 in the fixed cavity. In this case, the photovoltaic panel 30 can be fixed by opening a groove on the inner wall of the fixed cavity; or the photovoltaic panel 30 can be fixed in the frame 10 by bonding the peripheral side of the photovoltaic panel 30 and the inner wall of the fixed cavity with adhesive; or a receiving platform can be provided on the inner wall of the fixed cavity so that the photovoltaic panel 30 is placed on the receiving platform, and then a pressure block is connected to the frame 11 to clamp and fix the photovoltaic panel 30. In this way, the frame 11 is fixedly installed on the photovoltaic bracket under the action of the mounting member, so that the frame 11 can wrap and protect the photovoltaic panel 30, reduce the external force on the photovoltaic panel 30 when it is mounted on the photovoltaic bracket, and ensure the stable and reliable operation of the photovoltaic system 100.

[0034] By making the frame 11 out of a material having a certain thickness, the interior of the frame 11 can be hollowed out to form a flow space 111. By connecting the frame 11 with the first pipe 131 and the second pipe 133, the first pipe 131 and the second pipe 133 can be connected to the flow space 111, and then a certain amount of liquid such as clean water can be injected into the flow space 111 from the first pipe 131 or the second pipe 133, and the liquid in the flow space 111 can be discharged from the first pipe 131 or the second pipe 133, so that the frame 10 can have the function of storing a certain amount of liquid flow. By providing a water outlet structure 113 on the frame 11, the water outlet structure 113 can be a water outlet structure provided near the photovoltaic panel 30; or a nozzle structure connected to the frame 11 and provided toward the photovoltaic panel 30; or a cleaning device movably provided on the frame 11, so that the frame 10 can inject clean water into the flow space 111 through the first pipe 131 or the second pipe 133, and the water flow can be sprayed on the photovoltaic panel 30 through the water outlet structure 113, so that the water flow can flow on the surface of the photovoltaic panel 30 to wash away dust, sand and other debris attached to the surface of the photovoltaic panel 30, thereby achieving the cleaning function of the photovoltaic panel 30. Furthermore, the photovoltaic system 100 can not only use the frame 10 to fix the photovoltaic panel 30, but also use the internal space of the frame 10 to form a water flow channel for the cleaning system, which is conducive to reducing the pipe laying area in the photovoltaic power station and effectively improving the practicality and reliability of the frame 10.

[0035] Among them, the frame 10 can use the first pipe 131 as the water inlet end of the flow space 111 and the second pipe 133 as the water outlet end of the flow space 111. When the photovoltaic system 100 is arranged and installed according to a certain layout, the first pipe 131 and the second pipe 133 of the frame 10 of any two photovoltaic systems 100 can be connected and connected, and the flow spaces 111 in the frames 10 of multiple photovoltaic systems 100 can be connected in sequence. Then, when the frame 10 of the photovoltaic system 100 is filled with water, water can be injected from the first pipe 131 of a photovoltaic system 100 near the edge of the photovoltaic bracket, so that the water flows into the flow space 111 of the frame 10 of the photovoltaic system 100. 11, it can enter the flow space 111 of the frame 10 of another photovoltaic system 100 from the second pipe 133, so that the frames 10 of multiple photovoltaic systems 100 can be connected to form an integrated water network system, so that water can be stably injected into the flow space 111 of multiple frames 10, which is conducive to better reducing the area of pipes laid in the photovoltaic power station. At the same time, by using the flow space 111 in the frame 10 and the flow pipes 13 connected between the frames 10, it is possible to better avoid the interference of the pipes of the cleaning system on the photovoltaic bracket with the cables, effectively reduce the construction difficulty of the photovoltaic power station, improve the assembly convenience of the photovoltaic power station, and further improve the practicality and reliability of the frame 10. For example, the liquid flow network formed by the flow space 111 of the frames 10 of multiple photovoltaic systems 100 can be as follows Figures 1 to 4 As shown, the dotted line with an arrow in the figure represents the direction of water flow in the flow space 111.

[0036] The photovoltaic power station can also install a water supply mechanism 200 such as a water pump or a water pump at the water source, and use a pipe to connect the water supply mechanism 200 and the first pipe 131 of the frame 10 of the photovoltaic system 100 set at the edge of the photovoltaic bracket, so that the photovoltaic power station can use the water supply mechanism 200 to stably extract water from the water source and flow it into the flow space 111 of the frame 10 of multiple photovoltaic systems 100, ensuring that the frame 10 can stably output water to clean the photovoltaic panel 30, further improving the overall structural stability and reliability of the photovoltaic power station.

[0037] In addition, by using the flow pipe 13 to connect the flow spaces 111 in the frames 10 of multiple photovoltaic systems 100 to form a water network system, water can also flow inside the frames 10 of multiple connected photovoltaic systems 100, which is conducive to using the water flowing in the flow space 111 to carry away the heat released by the photovoltaic panel 30 on the frame 11, achieving a certain heat dissipation effect of the photovoltaic system 100, and thus reducing the number of devices for dissipating heat from the photovoltaic system 100 in the photovoltaic power station, or reducing the operating power of the devices for dissipating heat from the photovoltaic system 100, further improving the practicality and reliability of the frame 10. When the surface temperature of the photovoltaic panel 30 is too high, the photovoltaic system 100 can use the water outlet structure 113 to spray water onto the surface of the photovoltaic panel 30 to carry away the heat from the photovoltaic panel 30, thereby better improving the heat dissipation effect of the frame 10, so that the photovoltaic system 100 can operate under better working conditions and ensure the power generation efficiency of the photovoltaic power station.

[0038] In one embodiment of the present application, a flow space 111 is provided within the frame 11, and a water outlet structure 113 connected to the flow space 111 is provided on the frame 11. Clean water can be injected into the flow space 111 through the flow pipe 13, and the water in the flow space 111 can be sprayed from the water outlet structure 113 onto the photovoltaic panel 30, thereby cleaning and dissipating heat for the photovoltaic panel 30. Furthermore, the pipes of the photovoltaic power station cleaning system can be integrated into the frame 10, effectively reducing the number of pipes laid in the photovoltaic power station. Furthermore, when the photovoltaic system 100 is arranged and installed, for example, the first pipe 131 and the second pipe 133 on adjacent frames 10 can be connected, so that the frames 10 of multiple photovoltaic systems 100 can be connected in sequence to form a certain water network system. This helps to better reduce the number of cleaning pipes laid on the photovoltaic bracket, avoid interference between the cleaning pipes and the cables of the photovoltaic system 100, effectively reduce the construction difficulty and construction cost of the photovoltaic power station, and improve the practicality and reliability of the frame 10. It should be noted that the connection between the first pipe 131 and the second pipe 133 on adjacent frames 10 is only an example and not a limitation. In practice, it is only necessary to meet the requirement that when the photovoltaic system is arranged and installed, the first pipe on any frame can be connected to the second pipe on another frame.

[0039] See Figure 5 and Figure 6 In one embodiment of the present application, a first plug-in terminal 1311 is provided at the end of the first pipe 131, and a second plug-in terminal 1331 is provided at the end of the second pipe 133. The first plug-in terminal 1311 and the second plug-in terminal 1331 can be connected and connected in a coordinated manner.

[0040] In this embodiment, the flow pipe 13 can be provided with a first plug terminal 1311 at the end of the first pipe 131 facing away from the frame 11, and a second plug terminal 1331 can be provided at the end of the second pipe 133 facing away from the frame 11. The first plug terminal 1311 and the second plug terminal 1331 can be plug and socket structures that can be plugged into each other, and through holes are provided in the first plug terminal 1311 and the second plug terminal 1331 so that the through holes in the first plug terminal 1311 and the second plug terminal 1331 can be connected and connected after the first plug terminal 1311 and the second plug terminal 1331 are plugged and fixed. In this way, the photovoltaic power station can configure the second plug terminal 1331 at the water injection end of the device that supplies water to the frame 10, and the first plug terminal 1311 of the first pipe 131 can be plugged and connected with the second plug terminal 1331 of the flow supply device. In addition, the first pipes 131 and the second pipes 133 of the frames 10 of multiple photovoltaic systems 100 can be plugged and connected through the first plug terminal 1311 and the second plug terminal 1331, thereby ensuring stable water supply to the cleaning system. By utilizing the first plug-in terminal 1311 and the second plug-in terminal 1331 to realize the plug-in assembly of the first pipe 131 and the second pipe 133, the pipe connection convenience and reliability of the frame 10 can be better improved, which is conducive to better realizing the convenient assembly of the photovoltaic power station and further improving the practicality and reliability of the frame 10.

[0041] In addition, by using the first plug-in terminal 1311 and the second plug-in terminal 1331 to achieve the pipe connection assembly of the frame 10, it is more convenient to remove part of the photovoltaic system 100 for maintenance in the photovoltaic power station without the need to dismantle the photovoltaic system 100 as a whole, further improving the maintenance convenience of the photovoltaic power station.

[0042] See Figure 5 and Figure 6 In one embodiment of the present application, the water outlet structure 113 includes a first water outlet 1131 , which is disposed on the inner wall of the fixing cavity and faces the light-facing surface 31 of the photovoltaic panel 30 .

[0043] It can be understood that the photovoltaic panel 30 can integrate materials that absorb and convert light energy on one side of the panel. When the photovoltaic system 100 is installed and fixed on the photovoltaic bracket, the side panel of the photovoltaic panel 30 can be kept facing the light source. At this time, the panel surface of the photovoltaic panel 30 that is kept facing the light source can be set as the light-facing surface 31 of the photovoltaic panel 30, and the other side panel surface facing away from the light-facing surface 31 can be set as the backlight surface 33 of the photovoltaic panel 30. When the photovoltaic power station is operating, the light-facing surface 31 of the photovoltaic panel 30 is exposed above the photovoltaic bracket, and the dust and debris accumulated on the light-facing surface 31 are more than the dust accumulated on the backlight surface 33.

[0044] Therefore, the first water outlet 1131 of the water outlet structure 113 can be set on the inner wall of the fixed cavity and above the light-facing surface 31 of the photovoltaic panel 30. At this time, a gate can be set on the inner wall of the flow space 111 near the first water outlet 1131, and the flow and flow of water at the first water outlet 1131 can be controlled by opening and closing the gate; or a pipe connected to the first water outlet 1131 can be provided in the frame 11, and a valve component can be provided on the pipe. The flow rate of water discharged from the first water outlet 1131 can be regulated by controlling the valve opening of the valve component, and then by discharging the water in the flow space 111 from the first water outlet 1131, the water flow can be stably flowed to the light-facing surface 31 of the photovoltaic panel 30 to flush the dust and debris accumulated on the light-facing surface 31, thereby achieving a cleaning effect on the photovoltaic panel 30. By setting a first water outlet 1131 on the inner wall of the fixed cavity to achieve the cleaning of the photovoltaic panel 30 by the frame 10, the setting of the raised water outlet structure 113 on the frame 10 can be better reduced, avoiding the obstruction of the photovoltaic panel 30 by the water outlet structure 113, and better ensuring the full absorption and conversion of light energy by the photovoltaic panel 30, thereby further improving the practicality and structural reliability of the frame 10.

[0045] In one embodiment of the present application, the water outlet structure 113 is provided with a first nozzle, and the first nozzle is installed at the first water outlet 1131 .

[0046] In this embodiment, a first nozzle can be installed at the first water outlet 1131 so that the water flow in the flow space 111 can be sprayed from the first water outlet 1131 through the first nozzle toward the light-facing surface 31 of the photovoltaic panel 30. At this time, by adjusting the nozzle of the first nozzle, the first nozzle can be made to spray a water column with a higher flow rate or water pressure, so that the water outlet structure 113 can better clean dust or debris attached to the photovoltaic panel 30; or the first nozzle can be made to spray a diffuse water flow with a larger range, so that the water flow sprayed by the water outlet structure 113 can better act on the entire light-facing surface 31 of the photovoltaic panel 30, thereby achieving a better cleaning and heat dissipation effect on the frame 10, further improving the structural stability and reliability of the frame 10. In addition, the first nozzle can also be provided with a steering mechanism so that the first nozzle can be swung back and forth under the action of the steering mechanism, and then the swing of the first nozzle can be used to spray the water flow onto the entire light-facing surface 31 of the photovoltaic panel 30, thereby achieving a more comprehensive cleaning and heat dissipation effect of the frame 10 on the photovoltaic panel 30, further improving the practicality and reliability of the frame 10.

[0047] See Figure 6 and Figure 7 In one embodiment of the present application, the water outlet structure 113 further includes a second water outlet 1133 , which is disposed on the inner wall of the fixed cavity and faces the backlight surface 33 of the photovoltaic panel 30 .

[0048] In this embodiment, the frame 11 can be provided with a raised structure on the inner wall of the fixed cavity that is inclined toward the backlight surface 33 of the photovoltaic panel 30, and a second water outlet 1133 can be provided at the end of the raised structure so that the second water outlet 1133 can be better arranged close to the backlight surface 33 of the photovoltaic panel 30. At this time, a gate can be set in the flow space 111 near the second water outlet 1133, and the flow and flow rate of water at the second water outlet 1133 can be controlled by opening and closing the gate; or a valve component can be set in the raised structure, and the valve opening of the valve component can be controlled to regulate the flow rate of water discharged from the second water outlet 1133, and then by discharging the water in the flow space 111 from the second water outlet 1133, the water flow can be sprayed onto the backlight surface 33 of the photovoltaic panel 30 to flush away dust and debris accumulated on the backlight surface 33, or the water flow can be used to absorb heat on the backlight surface 33 of the photovoltaic panel 30 to achieve a cleaning and heat dissipation effect on the photovoltaic panel 30, thereby ensuring the stable operation of the photovoltaic system 100 and further improving the practicality and reliability of the frame 10.

[0049] In addition, in some embodiments, the frame 10 may be provided with only a first water outlet 1131 to spray water on the light-facing surface 31 of the photovoltaic system 100, thereby cleaning and dissipating heat of the photovoltaic system 100; while in other embodiments, the frame 10 may be provided with only a second water outlet 1133 to spray water on the backlight surface 33 of the photovoltaic system 100, thereby cleaning and dissipating heat of the photovoltaic system 100; or, in other embodiments, the frame 10 may be provided with both the first water outlet 1131 and the second water outlet 1133, thereby achieving stable cleaning and heat dissipation of the light-facing surface 31 and the backlight surface 33 of the photovoltaic system 100, thereby better improving the practicality and reliability of the frame 10.

[0050] In one embodiment of the present application, the water outlet structure 113 is provided with a second nozzle, and the second nozzle is installed at the second water outlet 1133 .

[0051] In this embodiment, a second nozzle can be installed at the second water outlet 1133 so that the water flow in the flow space 111 can be sprayed from the second water outlet 1133 through the second nozzle toward the backlight surface 33 of the photovoltaic panel 30. At this time, by adjusting the nozzle of the second nozzle, the second nozzle can be made to spray a water column with a higher flow rate or water pressure, so that the water outlet structure 113 can better clean dust or debris attached to the photovoltaic panel 30; or the second nozzle can be made to spray a diffuse water flow with a larger range, so that the water flow sprayed by the water outlet structure 113 can better act on the backlight surface 33 of the entire photovoltaic panel 30, achieving a better cleaning and heat dissipation effect on the frame 10, further improving the structural stability and reliability of the frame 10. In addition, the second nozzle can also be provided with a steering mechanism so that the second nozzle can be swung back and forth under the action of the steering mechanism, and then the swing of the second nozzle can be used to spray the water flow onto the backlight surface 33 of the entire photovoltaic panel 30, achieving a more comprehensive cleaning and heat dissipation effect of the frame 10 on the photovoltaic panel 30, further improving the practicality and reliability of the frame 10.

[0052] See Figure 8 In one embodiment of the present application, the frame 11 is provided with a drainage channel 115 , which passes through the inner wall of the fixed cavity and the outer wall of the frame 11 and is in communication with the fixed cavity.

[0053] In this embodiment, the frame 11 may be provided with a groove on the surface facing away from the photovoltaic support, and the two opposite inner side walls of the groove may be opened, so that the groove forms a drainage channel 115 of the frame 11; alternatively, a drainage hole may be provided in the frame 11 that penetrates the inner wall of the fixing cavity and the outer wall of the frame 11, so that the drainage hole forms the drainage channel 115 of the frame 11. Furthermore, after the overflow space 111 is sprayed onto the surface of the photovoltaic panel 30 through the water outlet structure 113 for cleaning or heat dissipation, the water flow carries the cleaned foreign matter or the heat generated by the photovoltaic panel 30 and is discharged from the drainage channel 115, thereby achieving a more stable and reliable cleaning and heat dissipation effect of the frame 10 on the photovoltaic panel 30, better preventing the sewage on the photovoltaic panel 30 or water with a certain temperature from flowing back into the overflow space 111 from the water outlet structure 113, and further improving the structural stability and reliability of the frame 10.

[0054] See Figure 5 and Figure 6 In one embodiment of the present application, a card slot is provided around the inner wall of the fixing cavity, and the card slot is used for clamping and fixing the photovoltaic panel 30 on all sides.

[0055] In this embodiment, the frame 11 can be provided with a card slot around the inner wall of the fixing cavity, and the notch of the card slot is exposed on the inner wall of the fixing cavity. By setting the slot width to be greater than or equal to the thickness of the photovoltaic panel 30, the photovoltaic panel 30 can be fixed on all sides by carding in the card slot, so that the frame 10 can surround and fix the photovoltaic panel 30, further improving the connection stability and reliability between the frame 10 and the photovoltaic panel 30. By carding the surrounding structure of the photovoltaic panel 30 into the card slot, the contact area between the frame 11 and the photovoltaic panel 30 can be better increased, so that the heat released from the photovoltaic panel 30 can be better transferred to the frame 11, and then the water flow in the flow space 111 can be used to take away the heat from the frame 11, so that the frame 10 can dissipate heat from the photovoltaic panel 30 more quickly, further improving the heat dissipation effect of the frame 10.
