DETAILED DESCRIPTION

[0023] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. Those skilled in the art will understand that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application.

[0024] Example 1:

[0025] As Figures 1-4As shown, a rotatable clamp for distributed rooftop photovoltaic modules includes a clamp assembly 2 for fixing at a position on a roof crest 1 and a clamp assembly 3 for fixing the photovoltaic modules. The clamp assembly 3 is installed in pairs on both sides of the clamp assembly 1. Wing-shaped connecting plates 4 are installed on both sides of the clamp assembly 1 along its length or width, and the clamp assembly 3 is installed on the wing-shaped connecting plates. The clamp assembly 1 includes a left clamping plate 5 and a right clamping plate 6 installed opposite to each other. Clamping parts 7 are installed at the bottom of the left and right clamping plates, forming a downward-opening clamping cavity 8. Fixing parts 9 are installed at the top of the left and right clamping plates. Cover plates 10 are movably installed on the left and right clamping plates. Wing-shaped connecting plates are installed on both sides of the cover plates. Mounting holes 11 that mate with the fixing parts are installed on the cover plates. External threads 12 are installed on the outer wall of the fixing parts. Nuts 13 are coaxially fitted on the fixing parts corresponding to the position above the cover plates. Fixing bolts are radially installed on the side wall of the fixing parts. 14. The upper part features a through-thread design, with nuts and bolts providing secondary reinforcement for a double-fixed structure. The second clamping assembly includes an upper clamping plate 15 and a lower clamping plate 16 installed opposite each other. An adjustable cavity 17 is formed between the upper and lower clamping plates to cooperate with the goose-wing-shaped connecting plate. A second clamping cavity 18 for fixing photovoltaic modules is formed on both sides of the upper and lower clamping plates. The installation height difference between the photovoltaic module and the roof crest in the second clamping cavity is 5mm, meeting the requirements for frameless, step-on photovoltaic modules. This clamping assembly can change the original layout of the photovoltaic panels, using parallel or perpendicular to the roof ridge, solving the problem of uniform installation requirements. The clamping assembly has a built-in locator for positioning and installation parallel to or perpendicular to the roof ridge. At the same time, the separate installation design of the first and second clamping assemblies solves the problem of the uniqueness of matching roof photovoltaic modules with roof panels caused by the different R&D paths of photovoltaic module manufacturers and the lack of standardization of photovoltaic module specifications and models.

[0026] Furthermore, an installation groove 19 is installed on the inner wall of the clamping cavity 2, and an elastic rubber pad 20 is installed in the installation groove. Anti-slip texture 21 is installed on the pressing surface of the elastic rubber pad, which can improve the stability of clamping.

[0027] Furthermore, reinforcing support plates 22 are installed side by side on the lower clamping plate corresponding to the adjustable cavity position to improve the overall structural strength of the clamping assembly two.

[0028] Example 2:

[0029] like Figure 5 , 6 As shown, the difference between this embodiment and embodiment 1 is that the clamp assembly and the goose wing-shaped connecting plate are integrally molded, which can reduce the overall production cost and facilitate rapid assembly. The mating surfaces of the left clamping plate 5 and the right clamping plate 6 are also designed with mutually cooperating protrusions and slots to ensure that the two are quickly positioned and installed.

[0030] Further, the clamping cavity one of the clamp assembly one has two shapes, respectively matches the metal roof board wave peak and the composite roof panel wave peak.
