[0023] Example:

[0024] like Figures 1-6As shown, an embodiment of the present invention provides a multifunctional photovoltaic mounting bracket, including multiple sub-mounting brackets 24, multiple sub-mounting brackets 24 are connected to each other, the sub-mounting brackets 24 include multiple horizontal tubes 1 and multiple vertical tubes 2, multiple vertical tubes 2 are fixed on the surface of the multiple horizontal tubes 1, the bottom of the multiple horizontal tubes 1 are rotatably and slidably connected to the retractable support legs 3, the bottom of the retractable support legs 3 are threadedly connected to the fine-tuning nuts 5, the bottom of the fine-tuning nuts 5 are rotatably connected to the base 4, and the two ends of the multiple horizontal tubes 1 and the multiple vertical tubes 2 are respectively provided with a first threaded connection The connector 7 and the second threaded connector 8, multiple sub-mounting brackets 24 are respectively connected through the first threaded connector 7 and the second threaded connector 8, the retractable support leg 3 includes a bottom tube 301 and a telescopic tube 302, a groove 303 is provided on one side of the telescopic tube 302, a spring 304 is provided inside the groove 303, one end of the spring 304 is fixed to the inner wall of the groove 303, and the other end is fixed with a clamping block 305, a plurality of clamping holes 306 are opened on the surface of the bottom tube 301, and the clamping block 305 is clamped into the inside of any clamping hole 306.

[0025] The second threaded connector 8 includes a threaded head 801 that is the same as the first threaded connector 7. The outer surface of the threaded head 801 is threadedly connected to a threaded sleeve 802. When the first threaded connector 7 is connected to the threaded head 801, the threaded sleeve 802 is threadedly connected to the outer surface of the first threaded connector 7. A sealing groove 701 is provided at one end of the first threaded connector 7. A sealing ring 803 is connected to one end of the threaded head 801. When the first threaded connector 7 is connected to the threaded head 801, the sealing ring 803 extends to the inside of the sealing groove 701 to perform a sealing function.

[0026] like Figure 2 、 Figure 3 and Figure 6 As shown, during assembly, the block 305 is pressed to disengage the block 305 from the hole 306, and the telescopic tube 302 can be pulled to engage the block 305 with the other hole 306, so that the height of the telescopic support leg 3 can be adjusted to make the heights of the front and rear telescopic support legs 3 different, and the inclination angle of the sub-mounting bracket 24 can be adjusted. When the two sub-mounting brackets 24 are docked, due to the different inclination angles of the front and rear brackets, the height of the telescopic support leg 3 can be fine-tuned by rotating the fine-adjusting nut 5 so that the first threaded connector 7 and the second threaded connector 8 of the front and rear sub-mounting brackets 24 are aligned, and then the threaded sleeve 802 is rotated to connect it to the first threaded connector 7 to achieve the connection between the two.

[0027] An extension pipe 9 is extended from the middle of one of the horizontal pipes 1, and a vertical pipe 11 is provided on the surface of the extension pipe 9. The top of the vertical pipe 11 is rotatably connected to a rotating nozzle 12. A plurality of threaded mounting holes 201 are provided on the surface of the vertical pipe 2. The threaded mounting holes 201 are convenient for installing photovoltaic panels. The spray holes of the rotating nozzle 12 are provided on the side. When water is sprayed out, it can rotate under the action of thrust, so that the spraying range is wider.

[0028] like Figure 2 As shown, the transverse tubes 1 of multiple sub-mounting brackets 24 are connected by a first connecting tube 19 and a second connecting tube 20 to form a cooling water guide channel. One end of the formed cooling water guide channel is connected to a return pipe 21, and the other end is connected to an outlet pipe 23. A circulating water supply tank 13 is arranged between the return pipe 21 and the outlet pipe 23. Several metal cold conduction plates 6 are connected between the two transverse tubes 1. The top of the metal cold conduction plate 6 is located on the same plane as the surface of the vertical pipe 2, which can play a cooling role and cool the back of the photovoltaic panel. A solenoid valve 10 is arranged between the extension tube 9 and the vertical pipe 11, and a water stop valve 22 is arranged on the return pipe 21. The circulating water supply tank 13 includes a cooling water tank 131 and a drive cavity 132. A water pump 14 is arranged inside the drive cavity 132. The pumping end of the water pump 14 is connected to the cooling water tank 131, and the outlet end of the water pump 14 is connected to the outlet pipe 23.

[0029] When water cooling circulation is required, the water pump 14 is started, and the water pump 14 pumps water from the cooling water tank 131 through the cooling water guide channel. The cooling water guide channel transfers the low temperature to the metal cold guide plate 6 to cool the bottom of the photovoltaic panel. The cold water returns to the cooling water tank 131 after heat exchange through the cooling water guide channel. When water spraying is required, the solenoid valves 10 on multiple sub-mounting brackets 24 are opened through an external controller connected to the solenoid valve 10 (not shown in the figure), and the water stop valve 22 at one end is closed, so that the cooling water guide channel forms a pipeline with one end closed. Then the water pump 14 is started to pump water from the cooling water tank 131. The water will be sprayed out from the rotating nozzle 12 to cool the surface of the photovoltaic panel.

[0030] like Figure 4 and Figure 5 As shown, a plurality of semiconductor refrigeration plates 15 are fixed to the side wall of the cooling water tank 131, and a plurality of metal cooling plates are arranged inside the cooling water tank 131. One end of the plurality of metal cooling plates is connected to the cold end of the semiconductor refrigeration plate 15, and the other end of the plurality of metal cooling plates is fixedly connected to the heat sink 16, and a plurality of through holes 133 are opened on the side wall of the driving cavity 132.

[0031] The water inside the cooling water tank 131 can be cooled by the semiconductor refrigeration sheet 15 , so that the water temperature inside the cooling water tank 131 is lower, thereby improving the heat dissipation and cooling effect on the photovoltaic panel.

[0032] The water pump 14 is a modified water pump, including a water pump impeller assembly 141 fixed on the outer wall of the cooling water tank 131 and a drive motor 142. An extension rod is installed between the driving end of the drive motor 142 and the rotating shaft of the water pump impeller assembly 141. The inner wall of the driving chamber 132 is rotated to connect the rotating rod 18. A cooling fan blade 17 is fixed at one end of the rotating rod 18. The cooling fan blade 17 is close to one end of the heat sink 16. The extension rod and the rotating rod 18 are driven by a belt and a pulley. The semiconductor refrigeration plate 15 transfers the heat of the cooling water tank 131 to the hot end, and dissipates it through the heat sink 16 and the cooling fan blade 17. The cooling fan blade 17 is linked to the operation of the water pump 14, thereby driving the cooling fan blade 17 to rotate, which is more energy-saving and environmentally friendly.

[0033] The above is only a preferred specific implementation method of this embodiment, but the protection scope of this embodiment is not limited to this. Any technician familiar with this technical field can make equivalent replacements or changes based on the technical solution and inventive concept of this embodiment within the technical scope disclosed in this embodiment, and they should be covered by the protection scope of this embodiment.
