[0035] The embodiment provides a fixed installation structure for an embedded photovoltaic panel on a building roof, as Figure 4 、 Figure 5 and Figure 8As shown, a driving mechanism is provided for each of the multiple second fixing units on the mounting frame 2. The driving mechanism includes a transmission seat 19 for mounting a driving motor or other power source, a shaft body 22 rotatably mounted on the side wall of the mounting frame 2, and a plurality of bidirectional lead screws 16. The plurality of bidirectional lead screws 16 are respectively mounted at one end of the two fixing plates 23 of each group of second fixing units. The transmission seat 19, the shaft body 22, and the bidirectional lead screws 16 are mounted on the same side. The shaft body 22 is arranged along the length direction of the mounting frame 2, and its length extends from the position of the first group of second fixing units adjacent to the first fixing frame 1 to the last group of second fixing units away from the first fixing frame 1. The multiple bidirectional lead screws 16 are arranged in a straight line along the length direction of the shaft body 22 and are all parallel to the shaft body 22. At the positions corresponding to both ends of each bidirectional lead screw 16 on the side wall of the mounting frame 2, there are two first supports 17. Both of the two first support plates 17 are fixed to the side wall of the mounting frame 2. Each bidirectional lead screw 16 is rotatably arranged between the corresponding two first support plates 17. The transmission blocks 15 at the ends of the two fixing plates 23 of each group of second fixing units are respectively threadedly connected to two different threaded segments in different directions of the bidirectional lead screw 16. A first gear 18 is rotatably arranged on the side wall of one of the first support plates 17, and the first gear 18 is fixed to the bidirectional lead screw 16. At the positions corresponding to both ends of the shaft body 22 on the side wall of the mounting frame 2, there are second support plates 20 respectively. The second support plates 20 are all fixed to the side wall of the mounting frame 2. The shaft body 22 is rotatably arranged between the two second support plates 20. The transmission seat 19 is rotatably arranged on the side wall of one of the second support plates 20, and the transmission seat 19 is fixedly connected to the shaft body 22.

The multiple second gears 21 are all fixedly sleeved on the shaft body 22, and the multiple second gears 21 correspond to and mesh with the multiple first gears 18 one by one.

[0036] Through the connection between the electric device and the transmission seat 19 and driving the transmission seat 19 to rotate, during the rotation of the transmission seat 19, each second gear 21 is driven to rotate through the second support plate 20. During the rotation of the second gear 21, when the bidirectional lead screw 16 is driven to rotate through the first gear 18, the two transmission blocks 15 approach each other, thereby realizing the mutual approach of the two fixing plates 23. After the two fixing plates 23 approach each other, the notch 27 on the fixed shaft 26 is located in the grooves 28 on the two fixing plates 23 to achieve the final fixation of the fixed shaft 26, that is, the final fixation of the mounting frame 13 and the mounting frame 2. The photovoltaic panel 14 can be directly integrally fixed to the mounting frame 13 or can be installed on the mounting frame 13 in a detachable fixing manner.

[0037] In the embodiment, as Figure 2As shown, the limiting component includes an elastic cord 7 and two chutes 8 respectively arranged on the side walls of the two mounting frames 2. The two chutes 8 are arranged on the same side and are disposed along the length direction of the mounting frame 2. A damping slider 4 is provided in each chute 8. A connecting block 5 is rotatably arranged on each damping slider 4. A fixing rod 6 is fixed on the side wall of each connecting block 5. The two ends of the elastic cord 7 are respectively fixed to the two fixing rods 6. During the process of unfolding the two mounting frames 2, through the sliding and resistance between the damping slider 4 and the chute 8, and in cooperation with the small-range stretching of the elastic cord 7, the two mounting frames 2 have a slower speed during the process of separating from each other, so as to facilitate the staff to unfold this device on the roof.

[0038] As Figure 3 shown, for the convenience of hoisting, the connecting component further includes a bolt 12. When the two mounting frames 2 are in a folded state, the fixing blocks 9 on the two second fixing frames 13 coincide. The bolt 12 passes through the through holes in the two fixing blocks 9, and a limiting plate 11 is arranged outside each fixing block 9. A rubber ring 10 is arranged between the two fixing blocks 9, and the two limiting plates 11 and the rubber ring 10 are both connected by the bolt 12. Hoisting holes 30 are respectively formed in the two limiting plates 11. The two mounting frames 2 are connected by the bolt 12 and hoisted by a hoisting mechanism. During the hoisting process, the two mounting frames 2 will not unfold to affect the hoisting, and during the hoisting process, due to the effect of the rubber ring 10, excessive collision between the two mounting frames 2 during the hoisting is avoided, so as to avoid damage to the mounting frames 2.

[0039] The working process of the present invention is as follows: When in use, first fold the two mounting frames 2. As Figure 1 shown, after folding, fix the rope through the two limiting plates 11, and cooperate with the hoisting equipment to hoist this device on the roof. Subsequently, through the rotation between the first fixing frame 1 and the mounting frame 2, unfold this device; during the process of unfolding the two mounting frames 2, through the sliding and resistance between the damping slider 4 and the chute 8, and in cooperation with the small-range stretching of the elastic cord 7, the two mounting frames 2 have a slower speed during the process of separating from each other, so as to facilitate the staff to unfold this device on the roof; through the rotation between the first fixing frame 1 and the mounting frame 2, this device can be fixed on the roof in both a horizontal state and a "V" shape state, so that this device can be fixed on different roofs. Then, through the fixing holes 25 on the first fixing frame 1, fix the first fixing frame 1 on the roof. Subsequently, rotate the second fixing frame 3, and fix the second fixing frame 3 on the roof through the fixing block 9 on the second fixing frame 3 to realize the fixation of this device and the roof.

[0040] Subsequently, the mounting frame 13 can be hoisted and placed in the mounting frame 2. During the process of placing the mounting frame 13 in the mounting frame 2, the fixed shaft 26 on the mounting frame 13 passes through the connection hole on the connecting plate 29 to achieve the preliminary fixation between the mounting frame 13 and the mounting frame 2. After placing each mounting frame 13 in sequence, through the connection between the electric device and the transmission seat 19, and driving the transmission seat 19 to rotate. During the rotation of the transmission seat 19, each second gear 21 is driven to rotate by the second support plate 20. During the rotation of the second gear 21, when the bidirectional lead screw 16 is driven to rotate by the first gear 18, the two transmission blocks 15 approach each other, thereby realizing the mutual approach of the two fixing plates 23. After the two fixing plates 23 approach each other, the notch 27 on the fixed shaft 26 is located in the grooves 28 on the two fixing plates 23 to achieve the final fixation of the fixed shaft 26, that is, the final fixation of the mounting frame 13 and the mounting frame 2. Finally, the photovoltaic panel 14 can be installed.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
