Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Specific implementation examples:

[0029] like Figures 1-6As shown, a rooftop photovoltaic support structure includes two supports 1, each made of aluminum alloy, which is lightweight and easy to install. Both supports 1 are installed on the roof using expanded-bottom anchor bolts. Each support 1 has a sliding groove 2 on its adjacent side. Two ends of a sliding plate 3 slide within the adjacent sliding groove 2. A mounting frame 4 is rotatably connected to the sliding plate 3 via a hinge. The mounting frame 4 is used to install photovoltaic panels 5 (installing photovoltaic panels 5 on the frame is a conventional technique and will not be described in detail here). A receiving groove 31 is provided on the sliding plate 3, within which a moving block 6 slides. A connecting rod 7 is rotatably connected to the moving block 6 via a hinge seat. The free end of the connecting rod 7 is rotatably connected to the mounting frame 4 via the hinge seat. A synchronous drive mechanism 8 is installed on the sliding plate 3 to drive the movement of the moving block 6. Through the connection of the connecting rod 7, the mounting frame 4 rotates relative to the sliding plate 3, thereby adjusting the tilt angle of the photovoltaic panel 5. The two supports 1 are equipped with... The rotating cleaning mechanism 9 includes a threaded rod 91 rotatably connected to any bracket 1 via a bearing seat (not shown in the figure) and a slide rod 92 fixedly connected to another bracket 1. One end of the threaded rod 91 is fixedly connected to the output end of a first servo motor 93 mounted on the same bracket 1. A movable frame 94 slides on the slide rod 92, and the other end of the movable frame 94 is threadedly connected to the threaded rod 91. A drive shaft 95 is rotatably connected to the movable frame 94. One end of the drive shaft 95 is fixedly connected to the output end of a drive motor 96 mounted on the movable frame 94. A soft brush 97 is fixedly connected to the shaft of the drive shaft 95. The output of the first servo motor 93 causes the threaded rod 91 to rotate, causing the movable frame 94 to move on the bracket 1. At the same time, the output of the drive motor 96 causes the drive shaft 95 to drive the soft brush 97 to rotate and clean the surface of the photovoltaic panel 5. The rotating cleaning can remove the dust adhering to the surface of the photovoltaic panel 5, improving cleaning efficiency.

[0030] like Figures 1-6 As shown, the bracket 1 has a positioning hole 10 that communicates with the slide groove 2, and the sliding plate 3 has a positioning rod 11 that is adapted to the positioning hole 10. After the two brackets 1 are installed on the roof, the positioning rod 11 is pulled out, the sliding plate 3 is slid into the slide groove 2 to a suitable position, and the positioning rod 11 is inserted into the positioning hole 10 and the sliding plate 3 to fix the position of the sliding plate 3.

[0031] like Figures 1-6As shown, the synchronous drive mechanism 8 includes a vertical plate 81 fixedly installed on the roof, a second servo motor 82 installed on the vertical plate 81, and a rotating rod 83 that passes through and is rotatably connected to the sliding plate 3. The rotating rod 83 has an external thread 831 on its body located in the receiving groove 31, so that the rotating rod 83 passes through and is threadedly connected to the moving block 6. A cross-shaped locking block 84 is fixedly connected to the end of the rotating rod 83 away from the second servo motor 82. In this embodiment, the locking block 84 has a cross-shaped cross section. A locking groove 85 that matches the locking block 84 is provided at the end of the rotating rod 83 near the second servo motor 82. In this embodiment, it is also cross-shaped. The output end of the second servo motor 82 is also fixedly connected to a cross-shaped locking block 84. After installing the two brackets 1, push the sliding plate 3 into the two sliding grooves 2. After inserting the sliding rod 92 to install the first sliding plate 3, install the subsequent sliding plates 3 in sequence. During installation, the locking blocks 84 and locking slots 85 on the two adjacent rotating rods 83 engage with each other. The locking slot 85 on the rotating rod 83 adjacent to the second servo motor 82 engages with the locking block 84 on the output end of the second servo motor 82. Through the output of the second servo motor 82, the locking blocks 84 engage with the locking slots 85, so that each rotating rod 83 rotates synchronously. Since the rotating rod 83 is threadedly connected to the moving block 6, the moving block 6, which slides in the receiving groove 31, moves within the receiving groove 31, causing the angles of the connecting rod 7 and the mounting bracket 4 to change, thereby synchronously adjusting the tilt angle of each photovoltaic panel 5.

[0032] like Figures 1-6 As shown, a baffle 98 is fixedly connected to the mobile frame 94. The baffle 98 can block the obstructions swept away by the soft brush 97, reduce the probability of the obstructions flying to the rear, and thus improve the cleaning efficiency of the photovoltaic panel 5 surface.

[0033] like Figures 1-6 As shown, multiple soft brushes 97 are fixedly connected along the circumference of the drive shaft 95. In this embodiment, three soft brushes 97 are fixedly connected. By setting multiple soft brushes 97, the cleaning frequency of the photovoltaic panel 5 is increased compared to a single soft brush 97, while the rotation speed of the drive shaft 95 remains unchanged, thus further improving the cleaning efficiency.

[0034] like Figures 1-6 As shown, a lifting ring 12 is fixedly connected to the support 1. The lifting ring 12 not only makes it convenient for workers to lift the support 1, but also allows the support 1 to be hoisted in conjunction with the lifting rope and crane.

[0035] The drive motor 96, the first servo motor 93, and the second servo motor 82 are all electrically connected to an external power supply and to a control unit (not shown in the figure).

[0036] The working principle of a roof photovoltaic support structure in this embodiment is as follows: After installing two supports 1 on the roof, pull out the positioning rod 11, slide the sliding plate 3 into the sliding groove 2 to a suitable position, insert the positioning rod 11 into the positioning hole 10 and the sliding plate 3, and then install each sliding plate 3 in sequence. During installation, the locking blocks 84 and locking slots 85 on adjacent rotating rods 83 cooperate to engage. The locking blocks 84 on the output end of the second servo motor 82 cooperate to engage with the locking slots 85 on the rotating rods 83 adjacent to the second servo motor 82. Then, install the upright plate 81 on the roof so that each rotating rod 83 can rotate synchronously under the drive of the second servo motor 82, so that the moving block 6 sliding in the receiving groove 31 is in contact with the moving block 6. The connecting rod 7 moves within the receiving groove 31, causing the angle between the connecting rod 7 and the mounting bracket 4 to change, thereby synchronously adjusting the tilt angle of each photovoltaic panel 5. When the surface of the photovoltaic panel 5 needs to be cleaned, the mounting bracket 4 is driven by the second servo motor 82 to rotate and approach the sliding plate 3, flattening the photovoltaic panel 5. After the mounting bracket 4 is flattened, the connecting rod 7 enters the receiving groove 31 without affecting the flattening of the mounting bracket 4. The output of the first servo motor 93 causes the threaded rod 91 to rotate, causing the moving bracket 94 to move on the support 1. At the same time, the output of the drive motor 96 causes the drive shaft 95 to drive the soft brush 97 to rotate and clean the surface of the photovoltaic panel 5. Rotation and cleaning can remove the dust adhering to the surface of the photovoltaic panel 5, improving cleaning efficiency.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
