DETAILED DESCRIPTION

[0023] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0024] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0025] like Figures 1 to 10 As shown, a portable and detachable photovoltaic support for sloped roofs includes a support base 110, and the support base 110 is provided with a groove-shaped portion 111 for the upper frame edge of the photovoltaic panel assembly to extend therein, and the lower side plate of the groove-shaped portion 111 is provided with a locking plunger 120 for locking the upper frame edge of the photovoltaic panel assembly; the top of the support base is provided with a guide groove 112 with an opening facing upward for supporting the lower frame edge of the photovoltaic panel assembly, and the guide groove is provided with a slider 140 that can slide relative to it, and the slider is fixedly connected with a limit baffle 130 for leaning against the outer side of the lower frame edge of the photovoltaic panel assembly, and the upper end of the limit baffle is provided with an upper pressure plate 131 for pressing the lower frame edge of the photovoltaic panel assembly. The photovoltaic panel assembly includes a frame body and a photovoltaic panel embedded in the frame body. The photovoltaic panel assembly is a prior art, and its structure is not specifically described here. The utility model photovoltaic support can connect a single group of upper photovoltaic panel assemblies or lower photovoltaic panel assemblies (the upper layer is located obliquely above the photovoltaic support, and the lower layer is located obliquely below the photovoltaic support), such as Figure 8 , 9As shown; two upper and lower adjacent photovoltaic panel components can also be connected, such as Fig.10 As shown. The lower part of the photovoltaic bracket forms a lower limiting structure for connecting the lower photovoltaic panel assembly at the groove portion 111, and the upper part of the photovoltaic bracket (i.e., the part above the guide groove 112) forms an upper limiting structure for connecting the upper photovoltaic panel assembly. The design of the slider and the guide groove is conducive to limiting and adjusting the position of the photovoltaic panel assembly; in this way, the two adjacent layers of photovoltaic panel assemblies can form a height difference, similar to the corrugated structure; most of the rainwater flows away from the top of the photovoltaic panel assembly, which has a better waterproof effect.

[0026] The photovoltaic bracket can realize the full assembly and installation of photovoltaic panel components without welding and self-tapping screws. It is easy to install with high efficiency and can realize the rapid installation and replacement of photovoltaic panel components. There is no rigid connection between adjacent photovoltaic panel components, so it is easy to disassemble and assemble. Each photovoltaic panel component can be disassembled separately without moving other photovoltaic panel components, so it can reduce maintenance channels and increase the utilization rate of roof area.

[0027] In this embodiment, a limiting sheet metal 150 is provided at the rear of the groove-shaped portion 111, and a lower pressure plate 151 is provided at the upper end of the limiting sheet metal for pressing the bottom of the upper frame edge of the photovoltaic panel assembly.

The water-guiding armor 170 has a water-guiding effect, which can prevent water from accumulating on the photovoltaic panel assembly, and when it rains, the rainwater will wash away the mud and sand together, and automatically clean up the accumulated mud and sand.

[0031] In this embodiment, the locking plunger 120 is a hexagon socket screw, a steel ball 121 is provided in the middle of the upper end of the hexagon socket screw, and a locking nut 122 is connected to the hexagon socket screw and is clamped on the bottom side of the groove portion.

[0032] In this embodiment, a fixing bottom plate 113 is welded to the lower end of the bracket base, and bolt holes are provided on the fixing bottom plate 113 so as to fix the fixing bottom plate to the sloping roof by screws.
