Technical Field

[0001] This utility model relates to the field of solar photovoltaic panels, and in particular to a flip-up solar photovoltaic panel rain shelter bracket. Background Technology

[0002] Currently, solar photovoltaic panels are all fixedly connected to vertical supports on the ground, with their front facing upwards all day. This leads to water stains mixed with dust settling on the front of the panels after rain, causing them to become dirty and reducing solar energy absorption. Therefore, the front of the photovoltaic panels needs to be cleaned and maintained at regular intervals. Manual maintenance significantly increases labor costs, while mechanical maintenance requires specialized equipment such as drones, which also increases costs. Therefore, we are considering designing a photovoltaic panel that can be sheltered from rain, reducing the frequency of cleaning and maintenance, and thus controlling costs. Utility Model Content

A drive component for driving rotation is connected to the hinge point of any connecting rod.

[0005] Furthermore, the side plate is perpendicular to the base plate and has a length.

The end of the upper base plate is fixed with a protrusion, and the protrusion has a lower-secondary hinge point and a lower-level hinge point at the front and back. One end of the curved connecting rod is connected to the upper-level hinge point and the other end is connected to the lower-level hinge point.

[0019] 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.

[0020] like Figure 1 The illustration shows a flip-up solar photovoltaic panel rain shelter bracket. The photovoltaic panel 1 is fixed face-up on a base 2. The photovoltaic panel 1 is conventionally rectangular, and the base 2 is also rectangular. Side plates 3 are fixed to both ends of the base 2 along its length. The side plates 3 are perpendicular to the base 2 and have a length that extends downwards. Straight connecting rods 4 and curved connecting rods 5 are hinged to the side plates 3. The other ends of both straight connecting rods 4 and curved connecting rods 5 are hinged to an upper base 6. The straight connecting rods 4 and curved connecting rods 5 are arranged in a staggered, intermittent pattern, meaning there is a gap between them to prevent contact, but they appear to cross each other when viewed from the side. The two ends of the curved connecting rods 5 are bends, and these bends are centrally symmetrical about the middle of the curved connecting rod 5.

[0021] Specifically, a first-level hinge point 7 is provided on the side plate 3 near the base 2, and a second-level hinge point 8 is provided on the side plate 3 away from the base 2. A protrusion 9 is fixed to the end of the upper base 6, such as... Figure 2 As shown, the convex seat 9 is provided with a lower secondary hinge point 10 and a lower primary hinge point 11 at the front and rear. One end of the curved connecting rod 5 is connected to the upper primary hinge point 7 and the other end is connected to the lower primary hinge point 11; one end of the straight connecting rod 4 is connected to the upper secondary hinge point 8 and the other end is connected to the lower secondary hinge point 10.

[0022] Considering that most photovoltaic panels 1 are rectangular, in order to ensure the stability of the photovoltaic panel 1, this embodiment uses two side plates 3 and two protrusions 9. The two side plates 3 and two protrusions 9 are arranged one-to-one at both ends of the length direction of the photovoltaic panel 1. Each set of corresponding side plates 3 and protrusions 9 is connected by a straight connecting rod 4 and a curved connecting rod 5. When used on other small-sized or positively oriented photovoltaic panels 1, only one set of side plates 3 and protrusions 9 can be used, in which the side plates 3 are fixed in the middle of the panel base 2, and the protrusions 9 are located in the middle of the upper base 6.

[0023] A drive assembly for driving rotation is connected to the hinge point of any link. The drive assembly can be connected to the next secondary hinge point 10 or the next primary hinge point 11. In the accompanying drawings of this embodiment, the next primary hinge point 11 is used as an example, and a rotating rod 12 is connected between the two next primary hinge points 11. Figure 1 The lower ends of the two connecting rods 5 are fixed to the rotating rod 12. The drive assembly includes a worm gear transmission group 13, in which the worm gear is coaxially connected to the rotating rod 12, and the worm is connected to the drive motor 14. The drive motor 14 drives the connecting rods 5 to rotate, and the straight connecting rod 4 is passively rotated, causing the photovoltaic panel 1 to flip 180°. After flipping, the state is as follows. Figure 3 As shown, at this time, the front of the photovoltaic panel 1 is facing down, which can prevent rainwater from falling on the front of the photovoltaic panel 1.

[0024] like Figure 2As shown, the bottom of the upper base 6 is fixed to the lower base 15 by bolts. The projected area of ​​the lower base 15 is larger than that of the upper base 6. The non-overlapping portion of the lower base 15 is fixed to the ground by bolts. The increased bottom area of ​​the lower base 15 enhances the stability of the entire device. The drive motor 14 of the drive assembly is fixed to either the upper base 6 or the lower base 15; in this embodiment, it is installed on the lower base 15.

[0025] Optionally, a diagonal brace 16 is fixed between the plate base 2 and the side plate 3, and a diagonal brace guard plate 17 is fixed between the diagonal brace 16 and the plate base 2, such as... Figure 4 As shown. The diagonal bracing plate 17 is used to increase the contact area between the diagonal bracing rod 16 and the plate base 2, thereby enhancing the stability of the connection between the side plate 3 and the plate base 2.

[0026] Optionally, a connecting plate 18 is fixedly connected between the two side plates 3, such as... Figure 5 As shown, the connecting plate 18 is located behind the side plate 3, which ensures the synchronicity of the movement of the two sets of connecting rods and does not affect the normal rotation of the connecting rods.

[0027] It should be noted that the electricity generated on the photovoltaic panel is transmitted to the power station or other energy storage devices via electrical wires. Because the electrical wires are flexible, the connection between the photovoltaic panel and the energy storage device is not affected when the panel is flipped. After flipping, the electrical wire interfaces on the photovoltaic panel are exposed upwards, so waterproofing at the interfaces can be done using standard methods. Furthermore, the interfaces can be designed on the side of the photovoltaic panel rather than the back, which can reduce the shaking of the electrical wires caused by flipping the panel.

[0028] Furthermore, the drive motor can be started remotely or automatically by connecting to an outdoor humidity sensor. For remote control, when rain is detected in the control room, a start signal is sent to the drive motor via an antenna, causing the photovoltaic panel to flip. For automatic control, when the outdoor humidity sensor detects that the humidity has reached a certain value, the control board connected to the humidity sensor automatically sends a start signal to the drive motor, causing the photovoltaic panel to flip.
