[0030] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0031] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0032] like Figure 1-12The photovoltaic integrated device on the building roof shown includes a pair of photovoltaic modules. The structures of the two photovoltaic modules are the same and can be symmetrical to each other by adjusting the appropriate angles. The photovoltaic modules include a center panel 1 with the largest area. The center panel 1 includes an isosceles frame 101. The two sides of the isosceles frame 101 are parallel, and the other two sides are equal in length. In fact, it is an isosceles trapezoid. The isosceles frame 101 is fixedly connected with a main photovoltaic panel 102, which is also the part with the largest lighting surface in the entire photovoltaic module. A limiting assembly 5 and a driving assembly 3 are arranged below the center panel 1, which are respectively located below the two parallel sides of the center panel 1, and are used to flexibly connect the center panel 1 to the building roof and provide support to the center panel 1 to ensure its stability.

[0033] Specifically: the driving component 3 is located below the upper bottom of the isosceles frame 101, that is, close to the narrow side parallel to the side of the isosceles frame 101. The specific structure of the driving component 3 includes a main hydraulic cylinder 302, which can provide a strong and stable supporting force. The two ends of the main hydraulic cylinder 302 are respectively connected to the upper bottom of the isosceles frame 101 and the roof of the building to form a rotating pair. In this way, when the inclination angle of the center plate 1 changes, the inclination angle of the main hydraulic cylinder 302 can also be adaptively changed. The lower surface of the upper bottom of the isosceles frame 101 is fixedly connected with a first articulated sleeve 103, and the upper movable end of the main hydraulic cylinder 302 is fixedly connected with an upper articulated plate 306, which is used to be rotatably connected to the first articulated sleeve 103 through an upper articulated shaft 307. The axis of the upper articulated shaft 307 Parallel to the upper bottom of the isosceles frame 101, that is, parallel to the swing axis of the center plate 1, the driving assembly 3 also includes a first roof plate 301 fixedly connected to the roof of the building. The first roof plate 301 is the metal truss structure on the roof of the building. It also serves as a reinforcement structure of the roof of the building and a part of the mounting base of the photovoltaic integrated device. The upper surface of the first roof plate 301 is fixedly connected to a lower articulated sleeve 305, and the lower end of the main hydraulic cylinder 302 is fixedly connected to a lower articulated plate 303, which is used to be rotatably connected to the lower articulated sleeve 305 through a lower articulated shaft 304. The axis of the lower articulated shaft 304 is parallel to the upper bottom of the isosceles frame 101, and is also parallel to the swing axis of the center plate 1, thereby ensuring that the center plate 1 and the main hydraulic cylinder 302 rotate synchronously.

[0034] The specific structure of the limiting component 5 includes a third roof plate 501 fixedly connected to the roof of the building, which is also a metal truss of the roof of the building. A support column 502 is fixedly connected to the upper surface of the third roof plate 501. The support column 502 is usually set in a vertical state and has many roots. An axial hole 503 is opened at the upper end of the support column 502. A second hinge shaft 504 with an axis parallel to the lower bottom of the isosceles frame 101 is inserted into the axial hole 503. A second hinge sleeve 104 is fixedly connected to the lower surface of the lower bottom of the isosceles frame 101 for rotationally connecting with the second hinge shaft 504. The center plate 1 can only rotate around the second hinge shaft 504 within a certain range. In order to improve the stability of the upper bottom of the isosceles frame 101, more than one main hydraulic cylinder 302 is usually provided. For example, three are provided in this embodiment.

[0035] The two symmetrical sides of the center plate 1 are movably connected to the side wing plates 2 through the hinge mechanism 6 respectively. The functions of the side wing plates 2 and the center plate 1 are the same, both of which are used to obtain solar energy and convert it into electrical energy, but the area of ​​the side wing plates 2 is significantly smaller than the center plate 1. The side wing plates 2 include a right-angled trapezoidal right-angled frame 201, and a secondary photovoltaic panel 202 which is also a right-angled trapezoid is fixedly connected to the right-angled frame 201. The hinge mechanism 6 includes a first hinge plate 601 and a second hinge plate 602. The first hinge plate 601 is fixedly connected to the oblique waist lower surface of the isosceles frame 101, and the second hinge plate 602 is fixedly connected to the oblique waist lower surface of the right-angled frame 201. The first hinge plate 601 and the second hinge plate 602 are rotatably connected by a hinge shaft 603, so that the side wing plates 2 can rotate relative to the center plate 1 along an axis parallel to the waistline.

[0036] A support assembly 4 is provided below the side wing plate 2 for providing a support force adapted to the angle of the side wing plate 2. The support assembly 4 includes a second roof plate 401 fixedly connected to the roof of the building. The second roof plate 401 has the same properties as the first roof plate 301 and the third roof plate 501. The difference is that the heights of the two ends of the second roof plate 401 are not the same, and one end is tilted relative to the other end. Of course, both ends of the second roof plate 401 are fixedly connected to the top of the building to ensure its own stability. The support assembly 4 also includes a secondary hydraulic cylinder 402 located between the right-angle frame 201 and the second roof plate 401, which is also used to generate a large support force. The upper movable end of the secondary hydraulic cylinder 402 is fixedly connected to the upper sphere 403. The right-angle frame An upper ball sleeve 203 is fixedly connected to the lower surface of the straight waist of 201, which is used to cooperate with the upper sphere 403 to form a ball pair. The lower end of the auxiliary hydraulic cylinder 402 is fixedly connected to the lower sphere 404. The upper surface of the second roof plate 401 is fixedly connected to the lower ball sleeve 405, which is used to cooperate with the lower sphere 404 to form a ball pair. In this way, the auxiliary hydraulic cylinder 402 has a higher angular freedom. When the inclination angle of the center plate 1 changes, the support assembly 4 can allow the side wing plate 2 to make adaptive angle adjustments. There is not only one auxiliary hydraulic cylinder 402. In this embodiment, there are two, and the upper spheres 403 corresponding to the two auxiliary hydraulic cylinders 402 are respectively located at the two ends of the waist of the right-angle frame 201, and the lower spheres 404 are located at the two ends of the second roof plate 401.

[0037] Working principle: The central panel 1 is constrained by the limiting component 5 and can swing along a fixed axis driven by the driving component 3, while the side panels 2 are constrained by the hinge mechanism 6 connected to the central panel 1. Under the adaptive adjustment of the supporting component 4, the angle relative to the central panel 1 will change, so that the main photovoltaic panel 102 and the auxiliary photovoltaic panel 202 can be recessed inward at the top crown of the tower to form multiple reflective surfaces, like diamonds, which can not only improve the lighting efficiency of the photovoltaic panels, but also enhance the high-end and aesthetic appearance of the building exterior.
