DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] Please refer to Figures 1-5 , the present invention provides an intelligent low-carbon photovoltaic building roof structure, including a base 1. A photovoltaic cavity 5 is provided in the middle of the base 1. Opening grooves 2 are provided on both inner walls of the photovoltaic cavity 5. A plurality of bushings 3 are fixedly connected to both sides of the opening groove 2. A pull rod assembly 7 is rotatably connected inside the bushing 3. An extension assembly 8 is slidably connected inside the opening groove 2. Photovoltaic panels 13 are provided on both the extension assembly 8 and the top of the base 1. Mounting plates 10 are fixedly connected to the four corners of the photovoltaic panel 13. Second strip-shaped holes 9 are provided in the middle of the four mounting plates 10. A pin assembly 6 is provided inside the second strip-shaped hole 9. Electric telescopic rods 4 are provided on both sides of the bottom of the photovoltaic cavity 5. A single-chip microcomputer controller 11 is provided on one side of the top of the base 1. A wind sensor 12 is provided on one side of the single-chip microcomputer controller 11.

[0021] Refer to Figure 2 and Figure 3 , further, the pull rod assembly 7 includes a long pull rod 71 and a short pull rod 75. A rectangular groove 73 is provided on the surface of the long pull rod 71. Rotating rods 72 are fixedly connected to both sides of one end of the long pull rod 71. Sliding grooves 74 are provided on both inner walls of the rectangular groove 73. Convex rods 76 are fixedly connected to both sides of one end of the short pull rod 75. A shaft rod 77 is fixedly connected to one side of the other end of the short pull rod 75. The surface of the convex rod 76 is slidably connected to the inside of the sliding groove 74. The extension assembly 8 includes an extension plate 81. Sliding blocks 82 are fixedly connected to both sides of the extension plate 81. Support grooves 83 are provided on both sides of the top of the extension plate 81. Rotating holes 84 are provided on both sides inside the support groove 83. A plurality of first strip-shaped holes 85 are provided on the surface of the extension plate 81, and the first strip-shaped holes 85 are matched with the second strip-shaped holes 9. A push plate 87 is fixedly connected to the middle of the bottom end of the extension plate 81. Card slots 86 are provided on both sides of the bottom of the first strip-shaped hole 85;

[0022] During use, when the electric telescopic rod 4 is activated, it pushes the push plate 87 to open the two-sided extension plates 81 to both sides. The sliding blocks 82 slide inside the opening and closing groove 2, enabling the stable extension of the extension plates 81. Then, during the extension of the extension plates 81, the long pull rod 71 is pulled by the rotating rod 72 rotatably connected inside the rotating hole 84. At this time, the convex rod 76 slides inside the sliding groove 74, and the surface of the convex rod 76 relatively rolls inside the sliding groove 74. When the extension plate 81 extends to the designated position, the convex rod 76 slides to the end of the sliding groove 74 and is limited. At this time, the extension assembly 8 is straightened to provide a pulling force for the extension plate 81, increasing stability. When retracting, the same principle is adopted and it will not affect the process of retracting the extension plate 81. Moreover, the wind sensor 12 located at the top of the base 1 can always detect the magnitude of the external wind force, and then the single-chip microcomputer controller 11 controls the electric telescopic rod 4 to control the opening and closing of the extension assembly 8. In case of strong wind weather, the extension plate 81 is automatically retracted into the photovoltaic cavity 5 to prevent damage from strong winds.

[0023] Refer to Figure 4 As shown in Figure 4 , the pin assembly 6 includes a plug rod 61. A rotating seat 65 is fixedly connected to the top of the plug rod 61. Locking rods 64 are provided on both sides of the bottom of the plug rod 61. A hard spring 63 is sleeved on the surface of the plug rod 61. One end of the hard spring 63 is fixedly connected to a support sliding sleeve 62.

[0024] During use, align the first strip-shaped hole 85 and the second strip-shaped hole 9, then insert the plug rod 61 into the hole, and insert the directions of the two sides with the locking rods 64 aligned with the vertical direction of the strip-shaped hole. The bottom of the support sliding sleeve 62 abuts against the surface of the mounting plate 10. Pinch the rotating seat 65 and press it down until it passes through the bottom of the first strip-shaped hole 85, and then rotate the plug rod 61. At this time, the direction of the locking rod 64 rotates 90°. Release the rotating seat 65, and the locking rod 64 is clamped into the inside of the card slot 86. At this time, the hard spring 63 is in a compressed state, and both ends are respectively fixedly connected to the rotating seat 65 and the support sliding sleeve 62, making the entire pin assembly 6 form a self-locking state to complete the fixation. The photovoltaic panels 13 installed on the top of the base 1 are installed and fixed in the same way, which is time-saving, labor-saving, convenient and fast.

[0025] When the embodiment of the present application is in use: Install the extension assemblies 8 to be installed on both sides into the photovoltaic cavity 5. Detect the magnitude of the external wind force through the wind sensor 12, and then control the electric telescopic rod 4 to expand and contract in the weather environment with or without strong wind through the single-chip microcomputer controller 11 to prevent damage from strong winds. The electric energy converted by the photovoltaic panels 13 is stored through the solar energy controller and can be used for the electrical equipment required by users. Solar energy is an inexhaustible energy source. Vigorously developing photovoltaic roofs can reduce the use of other non-renewable energy sources. Moreover, the process of converting solar energy into electric energy by the photovoltaic panels 13 is a green and environmentally friendly energy conversion process.
