[0027] In order to make the content of the present utility model easier to be clearly understood, the present utility model will be further described in detail below according to specific embodiments and in conjunction with the drawings.

[0028] As Figures 1-4 shown, a roof photovoltaic system that is convenient for assembly and splicing includes:

[0029] At least one photovoltaic component;

[0030] The photovoltaic component includes a photovoltaic bracket 1 and at least one photovoltaic panel assembly. The photovoltaic bracket 1 is installed on the roof. The photovoltaic panel assembly includes a sliding seat 21, a mounting seat 22 and a photovoltaic panel 23. The sliding seat 21 is slidably fitted on the photovoltaic bracket 1. The mounting seat 22 is installed on the sliding seat 21. The photovoltaic panel 23 is rotatably installed on the mounting seat 22;

[0031] The sliding seat 21 is adapted to slide to a predetermined position to adjust the installation position of the photovoltaic panel 23, and the photovoltaic panel 23 is adapted to rotate to a predetermined position to be deployed parallel to the roof plane.

[0032] In this embodiment, three photovoltaic panel assemblies are provided on a photovoltaic component.

[0033] Specifically, as Figures 2-3 shown, the sliding seat 21 is slidably fitted on the photovoltaic support 1 through at least one lead screw nut pair; wherein,

[0034] The lead screw nut pair includes:

[0035] a nut installed on the sliding seat 21;

[0036] a lead screw 31 installed on the photovoltaic support 1.

[0037] Specifically, as Figure 2 shown, a bearing seat 221 is provided on the mounting seat 22, and the photovoltaic panel 23 is installed on the bearing seat 221.

[0038] Specifically, as Figure 4 shown, the roof photovoltaic system facilitating assembly and splicing further includes a link assembly. The link assembly includes at least one first link 41 and at least one second link 42. The first link 41 is rotatably installed on the photovoltaic support 1, the second link 42 is rotatably installed on the sliding seat 21, the first link 41 is hinged to the adjacent second link 42, and two adjacent second links 42 are hinged to each other.

[0039] In this embodiment, the link assembly further enhances the stability and adjustment ability of the roof photovoltaic system. They are connected to each other by means of hinges to form a flexible mechanical linkage mechanism. Two adjacent second links 42 are hinged to each other through hinge points. The second links 42 coordinate with each other when the sliding seat 21 moves, so that the sliding seat 21 can maintain stability when moving, and at the same time, the sliding stroke of the sliding seat 21 is restricted.

[0040] Specifically, as Figures 2-3 shown, a guide rod 11 is further installed on the photovoltaic support 1, and a guide protrusion 111 is provided on the surface of the guide rod 11.

[0041] Specifically, as Figures 2-3 shown, a guide hole 211 adapted to the guide rod 11 is provided on the sliding seat 21, and a guide groove cooperating with the guide protrusion 111 is provided in the guide hole 211.

[0042] In this embodiment, when the sliding seat 21 slides along the photovoltaic support 1, the guide protrusion 111 will enter the guide groove in the guide hole 211, ensuring that the sliding seat 21 moves along a predetermined straight path and preventing it from deviating or rotating during the sliding process.

[0043] Specifically, as Figures 2-3As shown, a length marking post 12 is also installed on the photovoltaic support 1. A through hole 212 suitable for the length marking post 12 to pass through is provided on the sliding seat 21. The diameter of the through hole 212 is larger than the diameter of the length marking post 12. Scale markings are provided on the length marking post 12. Users can determine whether the sliding seat 21 has moved to a predetermined position or whether further fine-tuning is required by observing the scale markings on the length marking post 12, which greatly speeds up the installation speed and reduces the installation error.

[0044] Specifically, as Figures 1-2 shown, at least one first connecting part 231 and at least one second connecting part 232 are provided on the photovoltaic panel 23. The first connecting part 231 is provided on one side of the photovoltaic panel 23, and the second connecting part 232 is provided on the other side of the photovoltaic panel 23;

[0045] After two adjacent photovoltaic panels 23 are flipped to a certain angle, the first connecting part 231 on one photovoltaic panel 23 is engaged with the second connecting part 232 on the other photovoltaic panel 23.

[0046] In this embodiment, the first connecting part is hook-shaped, and the second connecting part is a groove. The hook shape and the groove are suitable for engagement. Two adjacent photovoltaic panels 23 can be flipped to a certain angle. This flipping action enables the first connecting part 231 on one photovoltaic panel 23 to be docked with the second connecting part 232 on the other photovoltaic panel 23. When the two photovoltaic panels 23 are correctly aligned, the first connecting part 231 and the second connecting part 232 are locked to each other by engagement, and the edges of the two photovoltaic panels are in contact, forming a continuous and flat photovoltaic surface, which helps to improve the overall aesthetics and power generation efficiency.

[0047] In this embodiment, materials are selected according to the area of the house roof first. First, the photovoltaic support 1 is fixed on the roof to ensure its stability and levelness. By rotating the lead screw 31 in the lead screw nut pair, the sliding seat 21 is adjusted to the required position, and fine-tuning can be performed according to the specific situation of the roof. The photovoltaic panel 23 is installed on the bearing seat 211, and the photovoltaic panel 23 is adjusted to a position parallel to the roof plane by rotation;

[0048] By flipping two adjacent photovoltaic panels 23 to a certain angle, the first connecting part 231 on one side of the photovoltaic panel 23 is engaged with the second connecting part 232 on the other side of the photovoltaic panel 23, so as to realize the tight connection between the photovoltaic panels.

[0049] In the specific embodiments described above, the technical problems solved by the present utility model, the technical solutions and the beneficial effects have been further described in detail. It should be understood that the above description is only the specific embodiments of the present utility model and is not used to limit the present utility model.
