[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Reference Figure 1-10The embodiment provides an assembled building photovoltaic roof module, including a roof panel 1, the front end and right side of the roof panel 1 are fixedly connected with a plug-in block 2, the rear end and left side of the roof panel 1 are provided with a plug-in slot 8, and the plug-in slot 8 corresponds to and matches the plug-in block 2; a protection component 3 is provided at the upper end of the roof panel 1, and a photovoltaic frame 4 is provided inside the protection component 3, and the photovoltaic frame 4 is rotatably installed in the protection component 3 through a support shaft 9, and rotates in the protection component 3 under the action of the support shaft 9, thereby changing the inclination angle of the photovoltaic frame 4. A photovoltaic panel 5 is fixedly connected to the upper end surface of the photovoltaic frame 4; transmission components 6 are provided on both sides of the protection component 3, and a power mechanism 7, an angle adjustment mechanism 10 and a reset component 11 are provided inside the protection component 3, and the power mechanism 7 is used to provide power to the angle adjustment mechanism 10, and the inclination angle of the photovoltaic frame 4 is adjusted by the angle adjustment mechanism 10.

[0031] Specifically, before installing the photovoltaic roof, the photovoltaic frame 4 is first assembled on the roof panel 1. During assembly, the photovoltaic frame 4 is installed inside the protective component 3. Under the action of the protective component 3, the photovoltaic panel 5 can be protected, and objects can be effectively prevented from hitting the photovoltaic panel 5 from the side. After the photovoltaic frame 4 is assembled, the photovoltaic panel 5 is installed on the photovoltaic frame 4. After the photovoltaic panel 5 is assembled, when assembling the roof panel 1, align the plug-in block 2 on the roof panel 1 with the plug-in groove 8, so that it is convenient to splice the two roof panels 1 together; in order to ensure that the roof panel 1 is firmly spliced, a first circular hole is opened on the upper end face of the plug-in groove 8, and a second circular hole is opened on the upper end face of the plug-in block 2, and the first circular hole corresponds to the second circular hole. During operation, after the roof panels 1 are spliced, the fixing bolts are passed through the first circular hole and the second circular hole, and the two roof panels 1 can be fixedly connected together. Since the photovoltaic panel 5 is installed on the roof panel 1 in advance, it is convenient to assemble the photovoltaic panel 5 together with the roof panel 1 when assembling the roof panel 1, thereby reducing the assembly time, avoiding drilling holes on the roof, and improving the protection of the roof; after the roof panel 1 is assembled, a power source is provided to the power mechanism 7, which can provide power to the angle adjustment mechanism 10, and at the same time, with the cooperation of the reset component 11, it is convenient to change the inclination angle of the photovoltaic frame 4; when the roof panel 1 needs to be transferred, the photovoltaic frame 4 is stored in the protective component 3, and as the photovoltaic frame 4 rotates downward, the internal space of the protective component 3 can be changed with the cooperation of the transmission component 6, thereby facilitating the storage of the photovoltaic frame 4 in the protective component 3.

[0032] In the embodiment, Figure 2 and Figure 6As shown, the protection assembly 3 includes a fixed frame 301 and a mobile frame 302. The fixed frame 301 is a concave frame, fixed above the roof panel 1, with the concave opening facing the side. The mobile frame 302 is slidably installed on the concave opening side of the fixed frame 301. The support shaft 9 is rotatably installed on the side of the fixed frame 301 away from the concave opening. One side of the photovoltaic frame 4 is fixedly connected to the support shaft 9. The mobile frame 302 and the fixed frame 301 form a square protection frame surrounding the photovoltaic frame 4 and the outside of the photovoltaic panel 5, thereby protecting the photovoltaic panel 5 and effectively preventing objects from hitting the photovoltaic panel 5 from the side. Figure 2 , Figure 3 , Figure 8 and Fig. 9 As shown, two groups of transmission components 6 are symmetrically arranged on both sides of the protection component 3, and each group of transmission components 6 includes a pressure plate 601, a limit seat 602, a moving rod 603 and a first transmission rod 604. The pressure plate 601 is fixedly connected to the edge of the photovoltaic frame 4, and the limit seat 602 is fixedly connected to the position of the upper frame opening of the fixed frame 301 corresponding to the pressure plate 601. The moving rod 603 is slidably connected inside the limit seat 602, and the moving rod 603 corresponds to the pressure plate 601. The first transmission rod 604 is rotatably connected to the lower end of the moving rod 603, and the end of the first transmission rod 604 away from the moving rod 603 is connected to the moving frame 302 through the first fixed shaft 605. The first fixed shaft 605 is fixedly connected to the moving frame 302, and the first transmission rod 604 is rotatably connected to the first fixed shaft 605.

[0033] When the photovoltaic rack 4 is stored, the photovoltaic rack 4 rotates downward along the support shaft 9 and is stored in the protection assembly 3. During the rotation of the photovoltaic rack 4, the pressing plate 601 is driven to move toward the moving rod 603. After the pressing plate 601 contacts the moving rod 603, the moving rod 603 is squeezed to slide downward inside the limit seat 602. As the moving rod 603 moves downward, the first transmission rod 604 and the first fixed shaft 605 cooperate to drive the moving frame 302 to slide forward inside the fixed frame 301, thereby increasing the internal space of the protection assembly 3 and facilitating the storage of the photovoltaic rack 4 inside the protection assembly 3. The ball bearing 12 can be movably connected inside the upper end of the moving rod. When working, by setting the ball bearing 12, the friction between the moving rod 603 and the pressing plate 601 can be reduced under the action of the ball bearing 12, thereby increasing the service life of the pressing plate 601 and the moving rod 603.

[0034] An assembled building photovoltaic roof module is provided in an embodiment, such as Figures 4 to 6As shown, the angle adjustment mechanism 10 is provided with two groups, which are symmetrically arranged in the fixed frame 301. Each group of angle adjustment mechanism 10 includes a bearing seat 1001, a screw rod 1002, a slider 1003 and a second transmission rod 1005. The bearing seat 1001 is provided with two, which are fixedly connected to the roof panel 1. The screw rod 1002 is rotatably connected between the two bearing seats 1001. The slider 1003 is threadedly connected to the outside of the screw rod 1002, and when the screw rod 1002 rotates, the slider 1003 can move along the screw rod 1002; the upper end of the second transmission rod 1005 is hinged to the photovoltaic frame 4, and the lower end is fixedly connected to the slider 1003 through the second fixed shaft 1004. Figure 1 , Figures 6 to 9 As shown, the power mechanism 7 includes a rotating shaft 701 and a transmission shaft 705. The rotating shaft 701 is rotatably connected to the inside of the fixed frame 301, and the rotating shaft 701 is located at one end of the two screw rods 1002 and is perpendicular to the two screw rods 1002. First bevel gears 703 are fixedly installed at the positions of the rotating shaft 701 corresponding to the two groups of screw rods 1002, and a second bevel gear 704 is fixedly connected to one end of the two screw rods 1002 adjacent to the rotating shaft 701, and the second bevel gear 704 is meshed with the corresponding first bevel gear 703 for transmission; both ends of the rotating shaft 701 extend to the outside of the fixed frame 301, and a transmission groove 702 with a hexagonal cross-section is opened at the end, the end face shape of the transmission shaft 705 is hexagonal, and the transmission shaft 705 matches the transmission groove 702.

[0035] When the photovoltaic rack 4 needs to be angle-adjusted, the power source is connected to the rotating shaft 701, and the rotating shaft 701 is controlled to rotate. As the rotating shaft 701 rotates, the two first bevel gears 703 on the rotating shaft 701 rotate, and the screw rods 1002 of the two sets of angle adjustment mechanisms 10 are driven to rotate with the cooperation of the two second bevel gears 704, and the sliders 1003 on the screw rods 1002 move, and then the photovoltaic rack 4 can be driven to rotate around the support shaft 9 with the cooperation of the second fixed shaft 1004 and the second transmission rod 1005, providing power for the photovoltaic rack 4, so that the inclination angle of the photovoltaic rack 4 can be changed, which is beneficial for the photovoltaic panel 5 to absorb light energy, or the photovoltaic rack 4 can be stored in the protective assembly 3. After the adjacent two roof panels of the present invention are spliced, the transmission shaft 705 can be inserted into the transmission groove 702 of the adjacent two roof panels to connect the rotating shafts in the adjacent two roof panels as a whole. After the roof panels are assembled, the angle adjustment of a row of photovoltaic racks 4 can be controlled at the same time by connecting a power source.

[0036] An assembled building photovoltaic roof module is provided in an embodiment, such as Figure 4 and Figure 5As shown, the reset assembly 11 includes a guide rod 1101 and a spring 1102. The guide rod 1101 is slidably connected inside the mobile frame 302. The guide rod 1101 is fixedly connected to the fixed frame 301. The circumferential surface of the guide rod 1101 is provided with a spring 1102. One end of the spring 1102 is fixedly connected to the mobile frame 302, and the other end of the spring 1102 is fixedly connected to the fixed frame 301. When working, when the mobile frame 302 moves forward, the mobile frame 302 can be moved more smoothly under the action of the guide rod 1101. Stable, and the movement of the movable frame 302 also stretches the spring 1102; when the photovoltaic frame 4 is unfolded, as the photovoltaic frame 4 rotates upward, the pressure plate 601 no longer presses the movable rod 603, and the movable frame 302 can be driven to move backward under the action of the stretching spring 1102, so that the movable rod 603 presses the pressure plate 601, which makes it convenient for the photovoltaic frame 4 to unfold. After the photovoltaic frame 4 is unfolded to a certain angle, the movable frame 302 is located at the lower end of the photovoltaic frame 4, which effectively reduces impurities falling from above into the inside of the protective component 3.

[0037] The working process of the present invention is as follows: when splicing the roof panels 1, it is necessary to match the plug-in blocks 2 of the roof panels 1 with the plug-in slots 8 to facilitate the splicing of the roof panels 1. When splicing the roof panels 1 left and right, it is also necessary to insert the transmission shaft 705 into the transmission slots 702 of the two adjacent roof panels 1, so that the rotating shafts in the two adjacent roof panels 1 can be connected as one, so that multiple rotating shafts 701 can be driven to rotate at the same time by connecting a power source. After the roof panels 1 are spliced, the power source drives the rotating shaft 701 to rotate. At this time, the screw rod 1002 can be driven to rotate under the cooperation of the first bevel gear 703 and the second bevel gear 704, and then the slider 1003 can be driven to move under the action of the screw rod 1002, and then the second fixed shaft 1004 and the second transmission rod 1005 can be driven to rotate around the support shaft 9, thereby changing the inclination angle of the photovoltaic frame 4, which is beneficial for the photovoltaic panel 5 to absorb light energy; at the same time, the photovoltaic frame 4 rotates upward, and the pressure plate 601 no longer presses the moving rod 603, and under the action of the tension spring 1102, the moving frame 302 can be driven to move backward, so that the moving rod 603 presses the pressure plate 601, so that the photovoltaic frame 4 is convenient for unfolding. After the photovoltaic frame 4 is unfolded to a certain angle, the moving frame 302 is located at the lower end of the photovoltaic frame 4, which effectively reduces impurities from falling from above into the inside of the protective component 3.

[0038] When the photovoltaic rack 4 is stored, the power source works in the reverse direction, and the photovoltaic rack 4 can be driven to rotate downward, thereby driving the pressure plate 601 to move downward. After the pressure plate 601 contacts the moving rod 603, the moving rod 603 will be squeezed to slide inside the limit seat 602. As the moving rod 603 moves downward, the first transmission rod 604 and the first fixed shaft 605 can cooperate to drive the moving frame 302 to slide forward inside the fixed frame 301, thereby increasing the internal space of the protective assembly 3, which is beneficial for the photovoltaic rack 4 to be stored inside the protective assembly 3.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
