In addition, the ventilation fan and the protective net are both fixed and cannot be disassembled, making subsequent cleaning and replacement very inconvenient. Therefore, the present invention proposes an energy-saving ventilation device for green buildings. Summary of the Invention
[0005] The purpose of this invention is to address the deficiencies in the existing technology by proposing an energy-saving ventilation device for green buildings.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: An energy-saving ventilation device for green buildings includes a frame assembly fitted and installed on an exterior wall, and a photovoltaic panel installed on the outside of the exterior wall.

[0023] The top of the water tank 6 is open, which can collect rainwater and can also be connected to an external water source to supply water for rinsing the components 8 for subsequent rinsing and cleaning of the photovoltaic panels 4.
[0024] Furthermore, the left and right sides of the frame component 1 are disassembled and installed to the installation holes of the outer wall through multiple anchor bolts 11. The ventilation assembly 2 includes a housing 21, with a duct at the center of the housing 21. A ventilation fan 22 is rotatably installed inside the duct and is driven by a drive motor 23. A sleeve 24 is fixed around the housing 21. The protective net assembly 5 includes an outer protective net 51 located outside the outer shell 21 and an inner protective net 52 located inside the outer shell 21. The outer protective net 51 and the inner protective net 52 each have a mesh corresponding to the branch pipe and the ventilation fan 22 at their center. Multiple bolt holes are opened around the outer protective net 51 and the inner protective net 52, and the bolt holes are coaxial with the sleeve 24. The outer protective net 51, the outer shell 21 and the inner protective net 52 are connected in series by connecting bolts 53. The upper and lower sides of the outer protective net 51 are connected and fixed to the inner top and inner bottom walls of the outer casing 21 by angle iron 54 and screws.
[0025] Furthermore, the inner top wall and the top wall of the frame assembly 1 are both provided with sliding grooves 12, and the upper and lower surfaces of the outer protective net 51, the outer shell 21 and the inner protective net 52 are all fixed with sliders 9, which slide and match the sliding grooves 12. Figure 3 The outer protective net 51, outer shell 21 and inner protective net 52 are sequentially connected by connecting bolts 53 and sliding match the slider 9 and the sliding groove 12, so that the outer protective net 51, outer shell 21 and inner protective net 52 are sequentially installed on the inner wall of the frame assembly 1, and then the frame assembly 1 is installed in the installation hole of the outer wall by anchor bolts 11.
[0026] Furthermore, the top of the outer casing 1 is connected and fixed to the bottom of the bracket 3 by connecting bolts 31, and the top of the bracket 3 is connected and fixed to the outer wall of the outer wall by multiple expansion bolts.

[0032] The water pump 81 in the flushing component 8 draws water from the water tank 6 and pumps it to the nozzle 83 through the water pipe 82. At this time, the nozzle can spray water to flush the surface of the photovoltaic panel 4. The flushing component 8 and the cleaning component 7 work together to efficiently flush and clean the surface of the photovoltaic panel 4, so that it can maintain high power generation efficiency.
[0033] The electrical equipment in the ventilation assembly 2, cleaning assembly 7, and flushing assembly 8 are powered by both mains electricity and the power source of the photovoltaic panel 4. Since the electricity generated by the photovoltaic panel 4 can power the ventilation assembly 2, cleaning assembly 7, and flushing assembly 8, their dependence on and consumption of mains electricity can be reduced.
