[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-7 This embodiment provides a solar roof structure for a green building, including a roof body 1 with several solar panels 2 and an underground water tank 4 located below the roof body 1. A water collection part 3 is provided at the bottom of the roof body 1, and the water collection part 3 is connected to the underground water tank 4 through a drain pipe 5. A rinsing mechanism 7 for cleaning the solar panels 2 is provided at the top of the roof body 1. Water in the underground water tank 4 is sent into the rinsing mechanism 7 through a connecting pipe 9 on the output end of a water pump 8.

[0026] In this utility model, the roof body 1 is built on top of the building wall. The solar panels 2 on the roof body 1 can convert light energy into electrical energy, which can not only meet the basic functional requirements of the building roof, but also effectively utilize solar energy for power generation, heating and other energy conversion and utilization. On rainy days, rainwater flows into the water collection part 3 through the gable roof body 1, and then into the underground water tank 4 through the drain pipe 5 for storage. When the surface of the solar panels 2 on the roof body 1 needs to be cleaned, the water pump 8 sends the rainwater stored in the underground water tank 4 through the connecting pipe 9 to the flushing mechanism 7, so that the solar panels 2 on the roof body 1 are flushed by the flushing mechanism 7, which maximizes the utilization of natural resources, reduces the dependence on clean water resources, and ensures that the solar panels 2 can absorb sunlight to the maximum extent, maintain a high power generation efficiency, and reduce the power generation loss caused by dust accumulation.

[0027] It should be noted that, as Figure 2 , Figure 5 and Figure 6 As shown, the underground water tank 4 is equipped with a filter assembly 6 connected to the drain pipe 5. The filter assembly 6 includes a connecting cylinder 61 connected to the underground water tank 4. A filter screen 62 is installed inside the connecting cylinder 61. The filter screen 62 is detachably connected to the connecting cylinder 61 through a positioning plate 621. A limiting nut 623 is installed on the positioning plate 621 through a positioning end 622 that passes through the filter screen 62 and abuts against the surface of the filter screen 62. A corrugated hose 51 connected to the connecting cylinder 61 is installed at the bottom of the drain pipe 5.

[0028] When rainwater from the collection section 3 enters the underground water tank 4 through the drain pipe 5, particulate impurities in the rainwater are filtered through the filter screen 62 in the connecting cylinder 61, thereby preventing particulate impurities from entering the underground water tank 4 and causing blockage of the flushing mechanism 7. When the filter screen 62 needs to be cleaned and replaced, the corrugated hose 51 at the bottom of the drain pipe 5 is first separated from the connecting cylinder 61. The corrugated hose 51 can be extended and retracted, so that after the corrugated hose 51 is separated from the connecting cylinder 61, there is a space above the connecting cylinder 61 for the filter screen 62 to be disassembled. At this time, the limiting nut 623 of the positioning end 622 on the positioning plate 621 is removed, and the filter screen 62 can be pulled out from the positioning plate 621 to disassemble the filter screen 62, which facilitates the cleaning and replacement of the filter screen 62.

[0029] Specifically, such as Figures 2-4 As shown, the flushing mechanism 7 includes a fixed pipe 72 arranged along the length of the roof body 1 via a bracket 71. A spray assembly 73 connected to the fixed pipe 72 and capable of angle adjustment is provided on the bracket 71. The spray assembly 73 includes a fixed seat 731 fixed on the bracket 71. A mounting plate 732 is rotatably connected to the fixed seat 731, and at least two nozzles 733 are provided on the mounting plate 732 along its length.

[0030] The water pump 8 has a connecting pipe 9 at its output end connected to one end of a fixed pipe 72. The water pump 8 sends rainwater stored in the underground water tank 4 into the fixed pipe 72 between the brackets 71, and then sprays it out through a nozzle 733 connected to the fixed pipe 72. The water sprayed out by the nozzle 733 washes the solar panel 2, thereby cleaning the solar panel 2 and removing the impurities attached to the surface of the solar panel 2. This ensures that the solar panel 2 can absorb sunlight to the maximum extent, maintain a high power generation efficiency, and reduce the power generation loss caused by dust accumulation.

[0031] It should be noted that the mounting plate 732 has adjusting discs 734 at both ends that cooperate with the fixing base 731, and the adjusting discs 734 are provided with fixing bolts 735 that pass through the fixing base 731. The nozzle 733 is connected to the fixing tube 72 through a rubber tube. The adjusting disc 734 has several bolt holes along its circumference. Therefore, each rotation of a bolt hole can achieve a certain angle adjustment. The two ends of the mounting plate 732 are rotatably mounted on the fixing base 731. After the fixing bolts 735 are removed, the mounting plate 732 is rotated, and then the fixing bolts 735 are screwed into the bolt holes of the adjusting disc 734 at the corresponding positions. The angle of the nozzle 733 can be flexibly adjusted according to the actual pollution level and area of ​​the solar panel 2, so that the water flow can accurately wash the area that needs to be cleaned, thereby achieving the effect of saving water resources.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
