Description

Technical Field

[0001] The present application relates to the technical field of green buildings, and in particular to a roof structure for green buildings. Background Art

[0002] Green buildings can effectively alleviate the urban heat island effect and reduce the energy consumption of buildings by planting green plants on the roof. Green plants can absorb solar radiation and reduce the temperature of the roof surface, thereby reducing the need for air conditioning. For example, the Nanyuan Green Cloud Rooftop Co-construction Garden is a typical case of roof greening. It not only provides community activity space, but also achieves the goals of low carbon and community participation through the concept of solar panels and co-construction gardens.

[0003] At present, a green building roof with light energy utilization function with announcement number CN215888992U includes a building body and a roof body arranged on the top of the building body. A drainage pipe is arranged at the bottom of the roof body, and a light energy component is arranged at the top of the roof body. At the same time, a green plant component is added, which can improve the space utilization rate of the house and firmly fix the planted green plants.

[0004] The photovoltaic building integrated assembly and photovoltaic building with announcement number CN219918778U include a photovoltaic unit, a bracket unit, a spray unit and a control unit. The photovoltaic unit is arranged on the roof of the building body, and a green space is formed between the photovoltaic unit and the roof of the building body for placing green plants.

[0005] Regarding the above-mentioned related technologies, the growth of green plants requires sunlight in many aspects. For example, if the green plants on the roof of a green building with light energy utilization function with announcement number CN215888992U are exposed to strong light for a long time, the leaves may be directly damaged, causing burn spots or withering on the leaves. If the photovoltaic building integrated component and the green plants in the photovoltaic building with announcement number CN219918778U are exposed to shade for a long time, the green plants may become slender and weak, making it difficult for the green plants to grow healthily. Summary of the invention

[0006] In order to enable green plants on the roof to grow appropriately, the present application provides a roof structure for a green building.

[0007] The present application provides a roof structure for a green building using the following technical solutions:

[0008] A roof structure for a green building, comprising:

[0009] A flat roof, on which a green plant layer and a support frame are arranged, on which a number of photovoltaic panels are installed;

[0010] A rotating platform, comprising a rotating member and a limiting member, wherein the rotating member is installed between the support frame and the photovoltaic panel, the limiting member is installed on the side of the support frame close to the east, and the limiting member is located in a horizontal position, the rotating member enables the photovoltaic panel to gradually rotate from facing the west to the east, and the limiting member is located on the rotation path of the photovoltaic panel;

[0011] The temperature control component includes a temperature-sensing airbag and a driving component. The side of the temperature-sensing airbag close to the photovoltaic panel is attached to the photovoltaic panel, and the driving component is fixedly connected to the temperature-sensing airbag. The driving component is connected to the rotating component so that the temperature-sensing airbag senses the temperature increase of the photovoltaic panel and drives the photovoltaic panel to gradually rotate toward the east.

[0012] By adopting the above technical solution, when the sun rises from the east in the morning and the sunlight temperature is lower, the photovoltaic panels are tilted to face the west, thereby reducing the photovoltaic panels' blocking of sunlight on the green plant layer, allowing the morning sunlight to smoothly shine on the green plant layer, allowing the green plant layer to grow better through photosynthesis.

[0013] As the sun gradually rises from the east, the sunlight gradually becomes stronger. After the sunlight shines on the photovoltaic panel, the temperature of the photovoltaic panel gradually rises. As the temperature of the photovoltaic panel gradually rises, the temperature-sensing airbag expands. The expansion of the temperature-sensing airbag drives the driving part to move. The movement of the driving part drives the rotating part to drive the photovoltaic panel to rotate, so that the inclined photovoltaic panel gradually rotates toward the horizontal direction, so that the photovoltaic panel finally abuts against the limit part and maintains a horizontal state, thereby blocking the strong light over the largest area, thereby preventing the green plant layer from being burned by the strong light. At the same time, the transpiration of the green plant layer can also cool the photovoltaic panel, thereby improving the photoelectric conversion efficiency of the photovoltaic panel.

[0014] The temperature-sensing airbag is used to sense the intensity of sunlight, and the angle of the photovoltaic panel is adjusted by the driving part and the rotating part. When the sunlight is weak in the morning, the tilt angle of the photovoltaic panel is close to parallel to the light, thereby minimizing the shielding of the sunlight, allowing the green plant layer to better photosynthesize, which is more suitable for the growth of the green plant layer. When the sunlight is strong at noon, the tilt angle of the photovoltaic panel is close to perpendicular to the light, thereby maximizing the shielding of the sunlight, preventing the green plant layer from being burned by strong light, and allowing the green plant layer to grow more appropriately.

[0015] Optionally, the rotating member includes a rotating shaft, which is fixedly connected to the supporting frame, and the edge of the photovoltaic panel is fixedly connected to a mounting shell, the mounting shell is provided with a rotating groove, the rotating shaft is inserted into the rotating groove, and a rotating gear is fixedly connected to the rotating shaft; the side of the temperature sensing airbag away from the rotating shaft is fixedly connected to the mounting shell, and the outer wall of the temperature sensing airbag is in contact with the photovoltaic panel, and the driving member includes a driving rack, which is fixedly connected to a side of the temperature sensing airbag close to the rotating shaft, and the driving rack is meshed with the rotating gear.

[0016] By adopting the above technical solution, the cooperation between the rotating shaft and the rotating groove enables the photovoltaic panel to rotate around the axis of the rotating shaft. The outer wall of the temperature-sensitive airbag is used to sense the temperature of the photovoltaic panel. When the temperature rises, the temperature-sensitive airbag expands, and the expanded temperature-sensitive airbag pushes the drive rack to move toward the rotating gear. The drive rack abuts against the meshing part of the rotating gear, so that the drive rack rotates around the rotating gear, thereby controlling the mounting shell and the photovoltaic panel to gradually rotate toward the horizontal. When the temperature drops, the temperature-sensitive airbag shrinks, and the shrinking temperature-sensitive airbag pulls the drive rack to reset, and the drive rack pulls the meshing part of the rotating gear, thereby controlling the mounting shell and the photovoltaic panel to gradually tilt.

[0017] The expansion and contraction of the temperature-sensitive airbag is utilized to control the extension and contraction of the drive rack, thereby controlling the rotation of the mounting shell and the photovoltaic panel.

[0018] Optionally, a plurality of rotating rods are connected to the mounting shell, each of which is fixedly connected to a rotating blade, the rotating blade is made of a heat-conducting material, the rotating blade is located on the side of the photovoltaic panel close to the flat roof, a control component is installed on the rotating blade, and the control component is connected to the rotating gear, so that when the photovoltaic panel is rotated to a horizontal position, the rotating blade rotates to a state perpendicular to the surface of the photovoltaic panel, and one end of the rotating blade is in contact with the photovoltaic panel.

[0019] By adopting the above technical solution, when the temperature of the photovoltaic panel is high, the control component controls one side of the rotating leaf to fit against the photovoltaic panel, and uses the good thermal conductivity of the rotating leaf to transfer the heat on the photovoltaic panel, thereby greatly increasing the heat dissipation area of ​​the photovoltaic panel, thereby improving the heat dissipation effect of the photovoltaic panel, and further improving the conversion efficiency of the photovoltaic panel.

[0020] Optionally, the surface of the rotating blade is smooth, and the rotating rod is parallel to the rotating axis.

[0021] By adopting the above technical solution, when the morning sunlight shines on the photovoltaic panel, making the temperature of the photovoltaic panel lower, the inclined and smooth rotating leaves can reflect the sunlight onto the green plant layer, so that the green plant layer can better carry out photosynthesis.

[0022] Optionally, the control member includes a control gear and a control rack, the control gear is coaxially fixedly connected to the rotating rod, the control rack is meshed with the control gear, and the control rack is meshed with the rotating gear.

[0023] By adopting the above technical solution, when the photovoltaic panel and the mounting shell rotate, the rotating gear drives the control rack to move, the control rack movement drives the control gear to rotate, and the control gear rotation drives the rotating blade to rotate. When the photovoltaic panel is in a horizontal position, the rotating blade fits on the photovoltaic panel to dissipate heat, and when the photovoltaic panel is tilted, the rotating blade refracts sunlight to facilitate photosynthesis of the green plant layer.

[0024] Optionally, the limiting member includes a limiting bracket and a limiting rod, the limiting bracket and the limiting rod are both horizontally arranged, the limiting bracket is fixedly connected to the support frame, the limiting rod is fixed to the limiting bracket, and the limiting rod is provided with a receiving groove and an abutment groove, the receiving groove is located on the rotation path of the photovoltaic panel on the same support frame, and the abutment groove is located on the rotation path of the photovoltaic panel on the adjacent support frame.

[0025] By adopting the above technical solution, the two adjacent photovoltaic panels are limited by the accommodating groove and the abutting groove respectively, so that the two photovoltaic panels can be seamlessly spliced ​​under strong sunlight, so that multiple photovoltaic panels can completely shield the strong light on the green plant layer, avoiding burns to the green plant layer by the strong sunlight.

[0027] By adopting the above technical solution, the booster pump uses a water delivery pipe to spray the water stored in the water tank to the photovoltaic panel through the cleaning nozzle, thereby cleaning the surface of the photovoltaic panel, so that the photovoltaic panel can remain clean for a long time.

[0028] Optionally, the cleaning nozzle is located on a side of the photovoltaic panel that is inclined upward.

[0029] By adopting the above technical solution, the cleaning nozzle is set on the side of the photovoltaic panel that is inclined upward, so that the water sprayed by the cleaning nozzle can flow along the inclined surface of the photovoltaic panel, so that the cleaning effect of the cleaning nozzle is better. At the same time, the water cleaned by the cleaning nozzle can flow along the photovoltaic panel to the green plant layer to irrigate the green plant layer.

[0030] Optionally, a dispersion plate is fixedly connected to a side of the mounting shell away from the cleaning nozzle.

[0031] By adopting the above technical solution, the arrangement of the dispersion plate enables the water flowing along the photovoltaic panel to hit the dispersion plate, causing the water to splash, thereby making the irrigation more uniform.

[0044] The following is combined with Figure 1-3 This application is described in further detail.

[0045] The embodiment of the present application discloses a roof structure for a green building.

[0046] Reference Figure 1-3 A roof structure for green buildings includes a flat roof 1, a rotating platform 2, and a temperature control component 3. A green plant layer 11 and a support frame 12 are provided on the flat roof 1, and a plurality of photovoltaic panels 13 are installed on the support frame 12. The rotating platform 2 includes a rotating member 21 and a limiting member 22. The rotating member 21 is installed between the support frame 12 and the photovoltaic panel 13. The limiting member 22 is installed on the side of the support frame 12 close to the east, and the limiting member 22 is located in a horizontal position. The rotating member 21 enables the photovoltaic panel 13 to gradually rotate from facing the west to the east, and the limiting member 22 is located on the rotation path of the photovoltaic panel 13. The temperature control component 3 includes a temperature-sensing airbag 31 and a driving member 32. The side of the temperature-sensing airbag 31 close to the photovoltaic panel 13 is attached to the photovoltaic panel 13, and the driving member 32 is fixedly connected to the temperature-sensing airbag 31, and the driving member 32 is connected to the rotating member 21, so that the temperature-sensing airbag 31 senses the temperature increase of the photovoltaic panel 13 and drives the photovoltaic panel 13 to gradually rotate to the east. After sensing the intensity of sunlight through the temperature-sensing airbag 31 , the driving member 32 and the rotating member 21 are driven to adjust the angle of the photovoltaic panel 13 so that the green plant layer 11 receives more suitable sunlight, thereby enabling the green plant layer 11 to grow more appropriately.

[0047] The green plant layer 11 in this embodiment is provided with two rectangular areas, and the length direction of the two rectangular areas of the green plant layer 11 is from west to east. The green plant layer 11 can be made of carpet grass, Sedum or Bermuda grass, etc. Bermuda grass is used in this embodiment. In other embodiments, green plants with better adaptability can also be selected according to the area where the building is located.

[0048] There are 9 support frames 12, and the 9 support frames 12 are distributed in a rectangular shape, so that there are 3 support frames 12 in the length direction of the rectangular area of ​​each green plant layer 11, so that the 3 support frames 12 in the middle are located between the two green plant layers 11, and each photovoltaic panel 13 is located above the green plant layer 11 and installed on the support frame 12, so that both sides of the 3 support frames 12 in the middle are rotatably connected to the photovoltaic panel 13.

[0049] Since the morning sunlight is usually soft and the ultraviolet radiation is relatively weak, it is beneficial to the growth of the green plant layer 11. The morning sunlight can gently promote the start of photosynthesis and help plants accumulate energy and nutrients required for growth. Therefore, in this embodiment, the photovoltaic panel 13 is tilted to the west, so that when the sun rises from the east in the morning, the photovoltaic panel 13 reduces the shielding of the sunlight on the green plant layer 11, so that the morning sunlight can smoothly irradiate the green plant layer 11, so that the green plant layer 11 can grow better through photosynthesis.

[0050] As the sun gradually rises from the east, the sunlight gradually becomes stronger, and the strong sunlight can easily cause burns to the green plant layer 11. After the sunlight shines on the photovoltaic panel 13, the temperature of the photovoltaic panel 13 gradually rises. As the temperature of the photovoltaic panel 13 gradually rises, the temperature-sensing airbag 31 expands, and the expansion of the temperature-sensing airbag 31 drives the driving member 32 to move. The movement of the driving member 32 drives the rotating member 21 to drive the photovoltaic panel 13 to rotate, so that the tilted photovoltaic panel 13 gradually rotates toward the horizontal direction, so that the photovoltaic panel 13 finally abuts against the limit member 22 to maintain a horizontal state, thereby blocking the strong light with the largest area, thereby preventing the green plant layer 11 from being burned by the strong light.

[0051] In this embodiment, the rotating member 21 includes a rotating shaft 211 and a rotating gear 212, and the driving member 32 includes a driving rack 321. Other embodiments may also use a temperature sensing resistor and a motor to drive the photovoltaic panel 13 to rotate.

[0052] The rotating shaft 211 is fixedly connected to the support frame 12, and the rotating gear 212 is coaxially fixedly connected to the rotating shaft 211. The edge of the photovoltaic panel 13 is fixedly connected to the mounting shell 14, and the mounting shell 14 is provided with a rotating groove 15. By inserting the rotating shaft 211 into the rotating groove 15, the cooperation between the rotating shaft 211 and the rotating groove 15 makes the photovoltaic panel 13 rotate around the axis of the rotating shaft 211, so that the direction of the rotating shaft 211 can be controlled to control the photovoltaic panel 13 to tilt toward the west, and the photovoltaic panel 13 can be gradually rotated from facing the west to the east.

[0053] The side of the temperature-sensing airbag 31 away from the rotating shaft 211 is fixedly connected to the mounting shell 14, and the outer wall of the temperature-sensing airbag 31 is in contact with the photovoltaic panel 13. The driving rack 321 is fixedly connected to the side of the temperature-sensing airbag 31 close to the rotating shaft 211, and the driving rack 321 is meshed with the rotating gear 212. In this embodiment, a limiting shell 33 is provided on the outer surface of the temperature-sensing airbag 31. The setting of the limiting shell 33 enables the temperature-sensing airbag 31 to more stably control the movement of the driving rack 321.

[0054] The outer wall of the temperature-sensing airbag 31 senses the temperature of the photovoltaic panel 13. When the temperature rises, the temperature-sensing airbag 31 expands, and the expanded temperature-sensing airbag 31 pushes the drive rack 321 to move toward the rotating gear 212. The drive rack 321 abuts against the meshing portion of the rotating gear 212, so that the drive rack 321 rotates around the rotating gear 212, thereby controlling the mounting shell 14 and the photovoltaic panel 13 to gradually rotate toward the horizontal. When the temperature drops, the temperature-sensing airbag 31 contracts, and the contracted temperature-sensing airbag 31 pulls the drive rack 321 to reset, and the drive rack 321 pulls the meshing portion of the rotating gear 212, thereby controlling the mounting shell 14 and the photovoltaic panel 13 to gradually tilt.

[0055] The expansion of the temperature-sensing airbag 31 when heated controls the extension of the driving rack 321, and the contraction of the temperature-sensing airbag 31 when cooled drives the contraction of the rack 321, thereby controlling the rotation of the mounting shell 14 and the photovoltaic panel 13, so that the photovoltaic panel 13 can sense the intensity of sunlight and adjust the angle of the photovoltaic panel 13, so that the green plant layer 11 can obtain more suitable sunlight.

[0056] As sunlight gradually becomes stronger, the power generation of the photovoltaic panel 13 also gradually increases. The light energy that is not converted into electrical energy during the photoelectric conversion process of the photovoltaic panel 13 will be dissipated in the form of heat energy. The temperature effect of the photovoltaic panel 13 will affect the intrinsic properties of the photovoltaic panel 13 material and the parameters characterizing the performance, thereby affecting its power generation efficiency. Therefore, the photovoltaic panel 13 needs to perform sufficient heat dissipation during the high-intensity photoelectric conversion process.

[0057] Reference Figure 3 and Figure 4 Therefore, a rotating rod 4, a rotating blade 41 and a control member 42 are installed on the mounting shell 14. The rotating blade 41 is made of a heat-conducting material, such as a magnesium alloy or an aluminum alloy. In this embodiment, an aluminum alloy is used. The rotating rod 4 is rotatably connected to the mounting shell 14. The rotating blade 41 is fixedly connected to the rotating rod 4. The rotating blade 41 is located on a side of the photovoltaic panel 13 close to the flat roof 1. One end of the control member 42 is connected to the rotating rod 4, and the other end is connected to the rotating gear 212.

[0058] When the photovoltaic panel 13 is in a horizontal state, that is, the photovoltaic panel 13 is performing high-intensity photoelectric conversion, the temperature of the photovoltaic panel 13 is relatively high. At this time, the control component 42 drives the rotating rod 4 to rotate to make the rotating blade 41 abut against the back of the photovoltaic panel 13, and utilizes the good thermal conductivity of the rotating blade 41 to transfer the heat on the photovoltaic panel 13, thereby greatly increasing the heat dissipation area of ​​the photovoltaic panel 13, thereby improving the heat dissipation effect of the photovoltaic panel 13, and further improving the conversion efficiency of the photovoltaic panel 13.

[0059] Meanwhile, the rotating blade 41 made of aluminum alloy in this embodiment has a smooth surface, and the rotating shaft rotating rod 4 of the rotating blade 41 is parallel to the rotating shaft 211 of the photovoltaic panel 13. Therefore, when the morning sunlight shines on the photovoltaic panel 13, making the temperature of the photovoltaic panel 13 lower, the inclined and smooth rotating blade 41 can reflect the sunlight onto the green plant layer 11, so that the green plant layer 11 can perform photosynthesis better.

[0060] The control member 42 in this embodiment includes a control gear 421 and a control rack 422. The control gear 421 is coaxially fixedly connected to the rotating rod 4. The control rack 422 and the driving rack 321 are arranged parallel to each other. The control gear 421 is located between the driving rack 321 and the control rack 422. One side of the control rack 422 is meshed with the rotating gear 212, and the other side is meshed with the control gear 421. When the photovoltaic panel 13 and the mounting shell 14 rotate, the rotating gear 212 drives the control rack 422 to move, the control rack 422 moves to drive the control gear 421 to rotate, and the control gear 421 rotates to drive the rotating blade 41 to rotate.

[0061] When the photovoltaic panel 13 gradually rotates to a horizontal position, the control rack 422 is driven to move by the rotating gear 212, and the control rack 422 drives the control gear 421 and the rotating rod 4 to rotate, thereby controlling the rotating blade 41 to fit on the photovoltaic panel 13, and utilizing the good thermal conductivity of the photovoltaic panel 13 to dissipate heat.

[0062] When the photovoltaic panel 13 gradually rotates to tilt, the rotating gear 212 drives the control rack 422 to move, and the control rack 422 drives the control gear 421 to rotate. Since the diameter of the rotating gear 212 is larger than the diameter of the control gear 421, the rotation angle of the control gear 421 is larger than the rotation angle of the control rack 422 relative to the rotating gear 212. Therefore, the rotation angle of the rotating leaf 41 is larger than the rotation angle of the photovoltaic panel 13, so that the leaf surface of the rotating leaf 41 is tilted downward with its back to the photovoltaic panel 13. Therefore, when the morning sunlight shines on the back of the photovoltaic panel 13, the rotating leaf 41 refracts the sunlight, and the refracted sunlight can shine more on the green plant layer 11, thereby facilitating the photosynthesis of the green plant layer 11.

[0063] Reference Figure 1-3A cleaning nozzle 5 is also installed on the installation shell 14. A water storage tank 51 is installed on one side of the flat roof 1. A water supply pipe 52 is connected to the water storage tank 51. The water supply pipe 52 is connected to the support frame 12 between the two rectangular green plant layers 11. The water supply pipe 52 extends along the support frame 12 to the rotating shaft 211, and is finally connected to the cleaning nozzle 5 on the installation shell 14 through the rotating shaft 211. A booster pump 53 is installed on the water supply pipe 52. The booster pump 53 is used to send the water stored in the water storage tank 51 to the cleaning nozzle 5 through the water supply pipe 52, so that the cleaning nozzle 5 sprays water on the surface of the photovoltaic panel 13 for cleaning and cleaning, so that the photovoltaic panel 13 can be kept clean for a long time.

[0064] In this embodiment, the cleaning nozzle 5 is located on the side of the photovoltaic panel 13 that is tilted upward. In other embodiments, the cleaning nozzles 5 may be installed on both sides of the photovoltaic panel 13. In this embodiment, by arranging the cleaning nozzle 5 on the side of the photovoltaic panel 13 that is tilted upward, the water sprayed by the cleaning nozzle 5 can flow along the inclined surface of the photovoltaic panel 13, so that the cleaning effect of the cleaning nozzle 5 is better. At the same time, the water cleaned by the cleaning nozzle 5 can flow along the photovoltaic panel 13 to the green plant layer 11 to irrigate the green plant layer 11 located below the photovoltaic panel 13.

[0065] In an optional embodiment, a dispersing plate 6 is fixedly connected to the side of the mounting shell 14 away from the cleaning nozzle 5, and there is a gap between the dispersing plate 6 and the photovoltaic panel 13, and a dispersing hole 61 is also opened on the dispersing plate 6. The dispersing plate 6 is arranged so that the water flowing along the photovoltaic panel 13 hits the dispersing plate 6, so that the cleaned water splashes, or is dispersed into each dispersing hole 61 and flows out, thereby making the irrigation more uniform.

[0066] The limiting member 22 in this embodiment includes a limiting bracket 221 and a limiting rod 222, both of which are arranged horizontally, the limiting bracket 221 is fixedly connected to the support frame 12, the limiting rod 222 is fixed to the limiting bracket 221, and the limiting rod 222 is provided with a receiving groove 223 and an abutting groove 224, the receiving groove 223 is located on the path of the photovoltaic panel 13 on the same support frame 12, the abutting groove 224 is located on the path of the photovoltaic panel 13 on the adjacent support frame 12, and a clearance hole 225 is provided at the bottom of the abutting groove 224, so that the clearance hole 225 is passed through by the dispersion plate 6. The setting of the clearance hole 225 facilitates the passage of the dispersion plate 6, and when the adjacent photovoltaic panels 13 are in a horizontal position, the limiting rod 222 is connected to the dispersion plate 6, so that the connection between the adjacent photovoltaic panels 13 and the support frame 12 is more stable.

[0067] The accommodating groove 223 and the abutting groove 224 are used to limit the two adjacent photovoltaic panels 13 respectively, so that the two photovoltaic panels 13 can be seamlessly spliced ​​under strong sunlight, so that multiple photovoltaic panels 13 can completely shield the strong light on the green plant layer 11 and avoid burns to the green plant layer 11 by the strong sunlight.

[0068] The implementation principle of a roof structure for a green building in an embodiment of the present application is as follows: when the soft sunlight shines from the east in the morning, the photovoltaic panel 13 is tilted to face the west, and at the same time, the leaf surface of the rotating leaf 41 is tilted downward with its back to the photovoltaic panel 13, so that when the sun rises from the east in the morning, the photovoltaic panel 13 reduces the blocking of sunlight on the green plant layer 11, and the tilted and smooth rotating leaves 41 can reflect the sunlight shining on the back of the photovoltaic panel 13 onto the green plant layer 11, so that the green plant layer 11 can better carry out photosynthesis.

[0069] As the sun gradually rises from the east, the sunlight gradually becomes stronger. After the sunlight shines on the photovoltaic panel 13, the temperature of the photovoltaic panel 13 gradually rises. As the temperature of the photovoltaic panel 13 gradually rises, the temperature-sensing airbag 31 expands. The expanded temperature-sensing airbag 31 pushes the drive rack 321 to move toward the rotating gear 212. The drive rack 321 abuts against the meshing part of the rotating gear 212, so that the drive rack 321 rotates around the rotating gear 212, thereby controlling the mounting shell 14 and the photovoltaic panel 13 to gradually rotate horizontally. At the same time, the rotating gear 212 drives the control rack 422 to move, and the control rack 422 moves to drive the control gear 421 to rotate. The control gear 421 rotates and drives the rotating blade 41 to rotate, so that the rotating blade 41 rotates until it gradually fits toward the back of the photovoltaic panel 13.

[0070] Until noon, when the sunlight is the strongest, the photovoltaic panel 13 rotates to a horizontal position. At this time, one end of the mounting shell 14 on the photovoltaic panel 13 abuts in the receiving groove 223, and the other end abuts in the abutting groove 224, so that the photovoltaic panel 13 can maintain a horizontal state, thereby receiving sunlight over a maximum area. At the same time, the rotating blade 41 rotates to a vertical state. At this time, the rotating blade 41 is attached to the back of the photovoltaic panel 13 and uses the good thermal conductivity of the rotating blade 41 to transfer the heat on the photovoltaic panel 13, greatly increasing the heat dissipation area of ​​the photovoltaic panel 13, thereby improving the heat dissipation effect of the photovoltaic panel 13, so that the photovoltaic panel 13 can increase the conversion efficiency of the photovoltaic panel 13 when the power generation is the largest.

[0071] As the sun gradually sets in the west, the sunlight gradually weakens, causing the power generation of the photovoltaic panel 13 to gradually decrease, and thus the temperature of the photovoltaic panel 13 gradually decreases. As the temperature of the photovoltaic panel 13 gradually decreases, the temperature-sensing airbag 31 contracts, and the contracted temperature-sensing airbag 31 pulls the drive rack 321 to reset, and the drive rack 321 pulls the meshing part of the rotating gear 212, thereby controlling the mounting shell 14 and the photovoltaic panel 13 to gradually tilt. At the same time, the rotating blade 41 is also synchronously reset to the blade surface facing away from the photovoltaic panel 13 and tilting downward.

[0072] The temperature-sensing airbag 31 is used to sense the temperature of the photovoltaic panel 13 to sense the intensity of sunlight, and the angle of the photovoltaic panel 13 is adjusted by the driving member 32 and the rotating member 21. When the sunlight is weak in the morning, the inclination angle of the photovoltaic panel 13 is close to parallel to the light, thereby minimizing the shielding of the sunlight. At the same time, the rotating leaves 41 also reflect the weaker sunlight onto the green plant layer 11, so that the green plant layer 11 can better carry out photosynthesis, which is more suitable for the growth of the green plant layer 11. When the sunlight is strong at noon, the inclination angle of the photovoltaic panel 13 is close to vertical to the light, thereby maximizing the shielding of the sunlight, preventing the green plant layer 11 from being burned by strong light, and allowing the green plant layer 11 to grow more appropriately. At the same time, the rotating leaves 41 are also in contact with the photovoltaic panel 13, so that the photovoltaic panel 13 can perform good heat dissipation when the power generation is maximum, so that the photoelectric conversion efficiency of the photovoltaic panel 13 is better.

[0073] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
