Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Reference Figures 1-6 This invention provides a rooftop adjustable photovoltaic module for energy-efficient buildings, comprising: The outer casing 1 has an opening at the top. Inside the outer casing 1, a lifting platform 2 is provided via a lifting assembly. The top of the lifting platform 2 is provided via a turntable 3 and an inclined frame 4 is provided. Several photovoltaic panels 21 are rotatably connected inside the inclined frame 4. The top of the turntable 3 is provided with a horizontal sliding assembly, which is hinged to one side of the inclined frame 4. A pitch adjustment assembly is also provided between the turntable 3 and the side wall of the inclined frame 4. The control components include a control unit 23 disposed within the housing 1 and a solar tracking sensor disposed on the tilt frame 4.

[0021] The main function of the lifting platform 2 is to adjust the height of the turntable 3. During normal use, the turntable 3 is raised to the top of the outer casing 1 to facilitate its rotation. In case of severe weather, the height of the turntable 3 and the tilting frame 4 is lowered so that the tilting frame 4 is below the top of the outer casing 1. The main function of the turntable 3 is to drive the tilting frame 4 to rotate following the sun's trajectory, so that the photovoltaic panel 21 can face the sun. The main function of the tilting frame 4 is to fix several photovoltaic panels 21. The main function of the horizontal sliding component is to move the tilting frame 4 backward when the photovoltaic panel is blocked by the projection of an adjacent photovoltaic module, thereby avoiding the projection area. The main function of the pitch adjustment component is to adjust the pitch angle of the tilting frame 4 so that the photovoltaic panel 21 can face the sun directly. At the same time, it can also control the tilting frame 4 to tilt to a horizontal position and fit against the turntable 3, so that the photovoltaic panel 21 can be lowered with the lifting platform 2 to below the top of the outer casing 1. The main function of the solar tracking sensor is to detect the position of the sun and provide a basis for the adjustment of the tilting frame 4. Overall, this invention, by setting up a pitch adjustment component and a horizontal sliding component, can adjust the tilt frame to a suitable pitch angle and also move the tilt frame horizontally to achieve the effect of moving the photovoltaic panel out of the projection area. At the same time, by setting up a lifting platform, after the tilt frame is adjusted to a horizontal state and is in contact with the turntable, the photovoltaic panel is lowered below the top of the outer casing by the lifting platform, thereby protecting the photovoltaic panel and enabling it to withstand severe weather such as strong winds, reducing the damage rate of the photovoltaic panel.

[0022] The scheme is further optimized. The horizontal sliding component includes a plurality of first slots 17 opened on the top of the turntable 3. The plurality of first slots 17 are arranged in parallel and are located near one side of the turntable 3. Second movable hinge seats 16 are slidably connected in the plurality of first slots 17. The plurality of second movable hinge seats 16 are respectively hinged to the side of the inclined frame 4 near the turntable 3. A movable driving component is provided between the second movable hinge seats 16 and the turntable 3. The moving drive component includes a third lead screw 15 rotatably connected to the first slot 17, the third lead screw 15 being arranged parallel to the first slot 17, a second moving hinge seat 16 being threaded onto the third lead screw 15, and a third motor 14 being drivenly connected to one end of the third lead screw 15.

[0023] like Figure 1 and Figure 4 As shown, when it is necessary to move the tilt frame 4 to the rear to avoid the projection area of ​​the adjacent photovoltaic module, the control unit can control the third motor 14 to rotate. The third motor 14 drives the third lead screw 15 to rotate. Through the threaded transmission between the third lead screw 15 and the second movable hinge seat 16, the second movable hinge seat 16 moves horizontally to the rear of the tilt frame 4, so that the photovoltaic panel 21 avoids the projection area. After the movement is completed, the pitch adjustment component synchronously adjusts the tilt frame 4 to a suitable angle so that the photovoltaic panel 21 faces the sun.

[0024] Further optimization of the scheme: the pitch adjustment component includes a second slot 18 opened on the top of the turntable 3. The second slot 18 is arranged parallel to the first slot 17, and the second slot 18 is located on the side of the top of the turntable 3 away from the first slot 17. One end of the telescopic rod 10 is hinged to the second slot 18 through a horizontal slide, and the other end of the telescopic rod 10 is hinged to the side wall of the tilt frame 4.

[0025] In a further optimized design, a fixed hinge seat 24 is fixedly connected to the side of the tilting frame 4 closest to the turntable 3, and the end of the telescopic rod 10 away from the turntable 3 is hinged to the fixed hinge seat 24.

[0026] The scheme is further optimized. The horizontal slide part includes a first movable hinge seat 12 that is slidably connected in the second slot 18. One end of the telescopic rod 10 is hinged to the first movable hinge seat 12. A second lead screw 11 is rotatably connected in the first slot 17. The first movable hinge seat 12 is threaded onto the second lead screw 11. One end of the second lead screw 11 is drivenly connected to a second motor 13.

[0027] like Figure 1 and Figure 4As shown, the telescopic rod 10 is an electric telescopic rod, and the pitch angle of the tilt frame 4 can be adjusted by changing the length of the telescopic rod 10. When the second movable hinge seat 16 moves, the second motor 13 can be controlled to drive the second lead screw 11 to rotate. Through the thread transmission of the second lead screw 11, the first movable hinge seat 12 moves horizontally accordingly. In conjunction with the length adjustment of the telescopic rod 10, the angle of the tilt frame 4 can be quickly adjusted.

[0028] Meanwhile, when it is necessary to keep the tilting frame 4 in a horizontal state, the first movable hinge seat 12 can be driven by the second motor 13 to slide towards the second movable hinge seat 16 while the telescopic rod 10 is shortened, so that the telescopic rod 10 falls into the second slot 18, thereby making the tilting frame 4 fit with the turntable 3.

[0029] The scheme is further optimized by having several openings 20 on the tilting frame 4, and several photovoltaic panels 21 are rotatably connected in the openings 20. Several flip motors 19 are fixedly connected in the tilting frame 4, and the flip motors 19 are connected to the photovoltaic panels 21 for transmission. The flip motors 19 are used to drive the photovoltaic panels 21 to flip at a certain angle.

[0030] like Figure 1 and Figure 5 As shown, to further protect the photovoltaic panel, before tilting the frame 4 is tilted to a horizontal position, the flipping motor 19 can be controlled to rotate the photovoltaic panel 21 by 180°, so that the light-receiving surface of the photovoltaic panel faces the turntable 3. Thus, when the tilting frame 4 is in a horizontal position, the back of the photovoltaic panel 21 faces upward, which can reduce the probability of damage to the photovoltaic panel 21.

[0031] In a further optimized design, a rotary motor 5 is vertically fixedly connected to the top of the lifting platform 2. The rotary motor 5 is connected to the bottom of the turntable 3 via a transmission connection, and the rotary motor 5 is used to drive the turntable 3 to rotate horizontally.

[0032] like Figure 2 As shown, the rotary motor 5 drives the turntable 3 to rotate, which in turn drives the tilting frame 4 to rotate with the movement of the sun.

[0033] The scheme is further optimized. The lifting assembly includes a fixed wedge block 6 fixedly connected to the bottom of the lifting platform 2 and a movable wedge block 7 horizontally slidably connected to the bottom of the inner side of the outer shell 1. The movable wedge block 7 is adapted to the fixed wedge block 6. A first lead screw 8 is horizontally rotatably connected inside the outer shell 1. The movable wedge block 7 is threaded onto the first lead screw 8. One end of the first lead screw 8 is drivenly connected to a first motor 9.

[0034] Further optimize the plan, such as Figure 2As shown, several vertical grooves 22 are respectively provided on the two opposite side walls inside the outer shell 1. Several sliders are fixedly connected to the side wall of the lifting platform 2. The lifting platform 2 is slidably connected to the several grooves 22 through the several sliders, so that the lifting platform 2 can be stably raised and lowered.

[0035] like Figure 3 As shown, when it is necessary to raise the lifting platform 2, the first motor 9 can be controlled to rotate by the control unit. The first motor 9 drives the first lead screw 8 to rotate. The first lead screw 8 drives the moving wedge block 7 to move to the right through the threaded transmission. Through the relative movement of the wedge surface with the fixed wedge block 6, the fixed wedge block 6 is pushed upward, thereby driving the lifting platform 2 to move upward.

[0036] Further optimization of the scheme: the solar tracking sensor device includes a solar tracking sensor 25, which is fixedly connected to the side wall of the tilting frame 4 away from the turntable 3.

[0037] like Figure 1 As shown, the main function of the solar tracking sensor 25 is to monitor the position of the sun and transmit the detection data to the control unit 23. The control unit 23 controls the operation of the rotary motor 5, the second motor 13 and the third motor 14 so that the photovoltaic panel 21 on the tilted frame 4 can always face the sun.

[0038] The scheme is further optimized. The control unit 23 includes a communication module 26 and a control module 27. The control module 27 is used to communicate with the cloud platform and is electrically connected to the photovoltaic panel 21, the lifting component, the horizontal sliding component, the pitch adjustment component, and the solar tracking sensor.

[0039] like Figure 3 and Figure 6 As shown, the communication module 26 can connect to the cloud platform to achieve real-time monitoring of power generation, power consumption, and energy storage, and optimize scheduling based on the building's energy consumption, thus supporting peak shaving and valley filling, and grid connection of surplus electricity. It matches the building's electricity load characteristics, prioritizing the supply to high-energy-consuming equipment such as lighting and air conditioning, reducing dependence on the power grid.

[0040] In a further optimized design, a storage battery 28 is fixedly connected inside the outer casing 1. The storage battery 28 is used to supply power to the communication module 26 and the control module 27.

[0041] like Figure 3 As shown, the main function of the storage battery 28 is to maintain the power supply required for the operation of the photovoltaic module itself.

[0042] The working process of this embodiment is as follows: During normal use, the lifting platform 2 is in a high position, and the turntable 3 can adjust its rotation angle according to the sun's position under the drive of the rotary motor 5. The tilting frame 4 is adjusted by controlling the telescopic rod 10 so that the photovoltaic panel 21 faces the sun. As the turntable 3 rotates, when the photovoltaic panel 21 is affected by the projection of adjacent modules, the control unit 23 can automatically control the operation of the second motor 13, the third motor 14, and the telescopic rod 10 to move the tilting frame 4 backward while maintaining a suitable tilt angle.

[0043] When encountering severe weather, the flip motor 19 drives the photovoltaic panel 21 to rotate 180°. Then, the first movable hinge seat 12 and the second movable hinge seat 16 move forward, and the telescopic rod 10 shortens, causing the tilting frame 4 to fall to the horizontal. Then, the first motor 9 lowers the height of the lifting platform 2 until the tilting frame 4 is below the top of the outer casing 1, so as to reduce the damage rate of the photovoltaic panel 21 in severe weather.

[0044] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0045] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.
