Furthermore, the design of building rooftops often fails to consider integration with other functions such as landscaping, recreation, and energy production, leaving their potential untapped. Rooftops, ideal for solar energy utilization, are underutilized in many buildings, leading to a waste of renewable energy. Utility Model Content

[0028] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0029] Rooftops, as ideal locations for solar energy utilization, are often underutilized in many buildings, leading to a waste of renewable energy. Utilizing rooftop space can save energy and achieve low-carbon or even zero-carbon goals. Furthermore, building rooftops, with their large area and often unused space, are excellent locations for solar energy utilization. If rooftops could be used for solar photovoltaic power generation, and hot air could be expelled through the roof's cavities via a surface breathing system, energy consumption inside the building could be reduced, thereby lowering overall building energy consumption.

[0030] This utility model provides a rooftop temperature control system based on solar photovoltaics, installed on the top of a building roof, such as... Figure 1 As shown, it includes: 1. Solar photovoltaic panel; 2. Photovoltaic combiner box; 3. Photovoltaic inverter; 4. Movable louvers; 5. Support frame; 6. Mechanical-electric-hydraulic support rod; 7. Gear transmission device; 8. Drainage gutter with electric heating function; 9. Anti-slip pull plate; 10. Interactive air vent; 11. Main structure; 12. Cavity layer; 13. Control unit; 14. Steel column; 15. Secondary beam; 16. Triangular bracket; 17. Steel beam; 18. Partition plate; 19. Battery pack; 20. Sensing device; 21. Control module.

[0031] The main structure 11 is installed on the top of the building roof; the steel support frame 5 is installed on the top of the main structure 11, including multiple sets of steel columns 14, secondary beams 15, triangular brackets 16, and steel beams 17. The steel columns 14 are vertically installed on the top of the main structure 11 to support the secondary beams 15. The steel beams 17 are installed between two sets of secondary beams 15. Triangular brackets 16 are provided on both sides of the top of the steel columns 14 to support the steel beams 17. A partition 18 is installed between the steel beams 17 and the top of the main structure 11. The partition 18 has reserved installation holes, which are fixed to the steel support frame 5 by expansion bolts. Figure 2As shown; the photovoltaic combiner box 2, photovoltaic inverter 3, control unit 13, and battery pack 19 are installed on the top of the main structure 11. The output end of the solar photovoltaic panel 1 is electrically connected to the input end of the photovoltaic combiner box 2, the output end of the photovoltaic combiner box 2 is electrically connected to the input end of the photovoltaic inverter 3, and the output end of the photovoltaic inverter 3 is electrically connected to the input end of the battery pack 19. The solar photovoltaic panel 1 is fixed to the steel support frame 5. The output end of the sensing device 20 is connected to the input end of the control module 21. The drainage gutter 8 with electric heating function and the anti-slip pull plate 9 are installed on the top of the steel support frame 5. The gear transmission device 7 is installed below the anti-slip pull plate. The gear transmission device 7 and the drainage gutter 8 with electric heating function are fixed to the secondary beam 15 of the steel support frame 5. The anti-slip pull plate 9 is fixed to the secondary beam 15 of the steel support frame 5 and connected to the mechanical electric drive hydraulic support rod 6. One end of the mechanical electric drive hydraulic support rod 6 is fixed to the steel support frame 5, and the other end is connected to the bottom surface of the solar photovoltaic panel 1 to support the solar photovoltaic panel 1. Photovoltaic panel 1, solar photovoltaic panel 1, and anti-slip pull plate 9 are all provided with reserved installation holes. Mechanical electric drive hydraulic support rod 6 is connected to the solar photovoltaic panel 1 and the anti-slip pull plate 9 with bolts through the reserved installation holes. Movable louvers 4 are installed on the south and north sides of the steel support frame 5. Movable louvers 4 are provided with reserved installation holes, which are fixed to the steel support frame 5 with expansion bolts. When the mechanical electric drive hydraulic support rod 6 pulls the solar photovoltaic panel parallel to the building roof, the movable louvers 4, partition 18, and solar photovoltaic panel 1 form a closed cavity layer 12. When the mechanical electric drive hydraulic support rod 6 supports the solar photovoltaic panel 11 upwards, the solar photovoltaic panel 1 and the top surface of the steel support frame 5 form an angle. The solar photovoltaic panel 1, mechanical electric drive hydraulic support rod 6, and the top surface of the steel support frame 5 form a triangular connection. An interactive air vent 10 is formed between the solar photovoltaic panel 1 and the anti-slip pull plate 9. Figure 3 As shown;

[0032] The working modes of the work unit include summer mode, winter mode, and daily mode, such as Figure 4 As shown;

[0033] In summer mode, the movable louver 4 is opened, the mechanical electric hydraulic support rod 6 is shortened, the solar photovoltaic panel 1 is lowered, the angle between the solar photovoltaic panel 1 and the steel support frame 5 is reduced, the anti-slip pull plate 9 is moved to the north side, the interactive air vent 10 is opened, the cavity layer 12 is connected to the outside, and the summer wind blows into the cavity layer 12 from the movable louver 4 and then blows out from the interactive air vent 10 on the upper layer of the cavity layer 12.

[0034] In winter mode, the movable louvers 4 are closed, the mechanical electric drive hydraulic support rod 6 is extended, the solar photovoltaic panel 1 is raised, the angle between the solar photovoltaic panel 1 and the steel support frame 5 is increased, the anti-slip pull plate 9 is moved to the south side, the air vent 10 is closed, and the cavity layer 12 is isolated from the outside. Winter wind blows from the outside and cannot enter the cavity layer 12, so cold air cannot enter the room. When the heat in the room dissipates to the outside, it is also reflected back into the room because the cavity layer 12 is isolated from the outside, thus playing a role in heat preservation.

[0035] In the daily mode, the mechanical electric hydraulic support rod 6 adjusts its extension length according to the angle and time of sunlight exposure, driving the anti-slip pull plate 9 and the solar photovoltaic panel 1 to move in the north-south direction, adjusting the angle between the solar photovoltaic panel 1 and the steel support frame 5;

[0036] When the working unit is in the summer mode, the control unit 13 controls the mechanical electro-hydraulic support rod 6 and the gear transmission device 7 to connect, opening the movable louver 4. Summer air flows through the movable louver 4, pushing the anti-slip pull plate 9 to the north, opening the interactive vent 10. Hot air in the cavity layer 12 is then exhausted outdoors through the interactive window 10 formed by the movement of the anti-slip pull plate 9. Figure 5 As shown;

[0037] When the working unit is in the winter mode, the control unit 13 controls the mechanical electric hydraulic support rod 6 and gear transmission device 7 to disconnect, close the movable louver 4, move the anti-slip pull plate 9 to the south side, close the interactive air vent 10, and form the cavity layer 12 on the top of the building to isolate the cold outdoor air from reaching the indoors.

[0038] When the working unit is in the daily mode, the sensing device 20 integrated within the solar photovoltaic panel senses the energy absorbed by the solar photovoltaic system. The control module 21 then controls the mechanically driven hydraulic support rod 6 and the gear transmission device 7 to form an angle conducive to solar energy absorption. Figure 6 As shown.

[0039] In this embodiment, during summer mode, environmental conditions are cleverly optimized and energy consumption is reduced through movable louvers 4 and anti-slip pull plates 9. Summer winds enter the cavity layer 12 of the building roof through the movable louvers 4. At this time, the anti-slip pull plates 9 move to the north, and the interactive vents 10 open accordingly. After passing through the cavity layer 12, the summer winds are blown outward through the interactive vents 10. Simultaneously, the anti-slip pull plates 9 move to the north, forming a shading area between the solar photovoltaic panels 1 and the building roof. Figure 7 As shown, this reduces sunlight exposure to buildings, lowers roof temperatures, and improves the efficient use of solar energy.

[0040] In this embodiment, during winter mode, the movable louvers 4 and anti-slip pull plate 9 are closed, and the solar photovoltaic panel 1, movable louvers 4, and partition 18 are closed, forming a cavity layer 12 that becomes a warm haven, effectively isolating cold air in the air and providing insulation for the interior, reducing indoor temperature loss, and replenishing building energy consumption through the energy absorbed by the solar photovoltaic panel 1. During winter snowfall, the solar photovoltaic panel automatically enters snow removal mode, and the accumulated snow slides down to the drainage gutter 8 with electric heating function due to gravity, and is melted and discharged through the solar electric heating system. This process not only keeps the building surface clean, but also effectively reduces building energy consumption, maximizes energy utilization, and ensures the comfort and functionality of the building.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope defined by the claims of the present invention.
