The simple and easy mounting structure of solar photovoltaic assembly
Technical field
The utility model relates to a kind of solar energy photovoltaic system, the simple and easy mounting structure of particularly a kind of solar photovoltaic assembly.
Background technology
Solar energy power generating has obtained using comparatively widely as a kind of emerging green energy resource.But because the area without shade on the top that generally is installed on building of photovoltaic module, so its mounting structure especially will be considered easily assembling, performance such as light, stable, safe.But the loading and unloading that the present photovoltaic system that uses has are easy, but exist the bad problem of stability; What have stablizes, but exists the problem that loading and unloading bother, weight is big.
Summary of the invention
The purpose of this utility model is exactly the weak point in the background technology, provides a kind of solar photovoltaic assembly simple and easy mounting structure, and it has simple in structure, in light weight, easy to loading and unloading, good stability.
In order to achieve the above object, the utility model adopts following technical scheme: the simple and easy mounting structure of solar photovoltaic assembly, comprise some photovoltaic modulies, it also comprises the attachment rail of some arranged askew, described attachment rail cross section is I shape, the mounting groove in the web left side of attachment rail is the A groove, the mounting groove on web right side is the B groove, the B groove of the attachment rail that the A groove of the attachment rail that horizontal level is higher and horizontal level are lower is oppositely arranged, and the photovoltaic module plate is installed and is arranged between the A groove and B groove of two adjacent groups attachment rail.
For a kind of optimization of the present utility model, first time second lower wing plate of A groove downside and the angle β of web are that 75 degree are to 86 degree, the cross-sectional width a of first upper flange of A groove upside is less than the cross-sectional width b of first lower wing plate, and the cross-sectional width c of second upper flange of B groove upside is less than the cross-sectional width d of second lower wing plate of B groove downside.
For a kind of optimization of the present utility model, second lower wing plate and web junction are provided with the water guide groove.
For a kind of optimization of the present utility model, described attachment rail downside is provided with the holddown groove that is connected with fixed mount.
For a kind of optimization of the present utility model, the track mounting plane that attachment rail constituted of some arranged askew and the angle α of horizontal plane are that 20 degree are between 60 degree.
The utility model is compared with background technology, has simple in structurely, and photovoltaic module is positioned between the A groove and B groove of two adjacent groups attachment rail, and its mounting means is simple, and convenient disassembly, connective stability are good, and overall weight is light.

Embodiment
Embodiment 1: with reference to Fig. 1 ~ 5.The simple and easy mounting structure of solar photovoltaic assembly, comprise some photovoltaic modulies 2, it also comprises the attachment rail 1 of some arranged askew, described attachment rail 1 cross section is I shape, the mounting groove in the web 1-4 left side of attachment rail 1 is A groove 1a, the mounting groove on web 1-4 right side is B groove 1b, and the B groove 1b of the attachment rail 1 that the A groove 1a of the attachment rail 1 that horizontal level is higher and horizontal level are lower is oppositely arranged, and photovoltaic module plate 2 is installed and is arranged between the A groove 1a and B groove 1b of two adjacent groups attachment rail 1.First lower wing plate 1-1 of A groove 1a downside and the angle β of web 1-4 are that 75 degree are to 86 degree, the cross-sectional width a of the first upper flange 1-2 of A groove 1a upside is less than the cross-sectional width b of the first lower wing plate 1-1, and the cross-sectional width c of the second upper flange 1-3 of B groove 1b upside is less than the cross-sectional width d of the second lower wing plate 1-5 of B groove 1b downside.The second lower wing plate 1-5 and web 1-4 junction are provided with water guide groove 1-6.Described attachment rail 1 downside is provided with the holddown groove 1c that is connected with fixed mount.Vertical range between the minimum distance between the first lower wing plate 1-1 and the first upper flange 1-2 and the second upper flange 1-3 and the second lower wing plate 1-5 is greater than the thickness of photovoltaic module 1.The track mounting plane 3 that the attachment rail 1 of some arranged askew is constituted and the angle α of horizontal plane 4 are that 20 degree are between 60 degree.
What need understand is: though present embodiment is to the utility model detailed explanation of contrasting; but these explanations; just to simple declaration of the present utility model; rather than to restriction of the present utility model; any innovation and creation that do not exceed in the utility model connotation all fall in the protection range of the present utility model.
