The photovoltaic module on type roof, light steel roof truss slope is provided with structure
Technical field
The utility model relates to the photovoltaic power generation technology field, and the photovoltaic module that relates in particular to type roof, a kind of light steel roof truss slope is provided with structure.
Background technology
In the photovoltaic generation engineering, according to the principle of photovoltaic generation, the angle of slope of photovoltaic module has influence on the generated energy of whole generating engineering to a great extent.Aforementioned angle of slope is meant the angle between photovoltaic cell (also claiming solar cell) square formation plane and the level ground.According to the analytical calculation of a plurality of parameters such as engineering location latitude, can obtain in theory one make the photovoltaic cell square formation one-year age in the cycle generated energy be maximum optimum incline angle.But in practice of construction, be limited by multiple factors such as construction environment, actual angle of slope general with above-mentioned optimum incline angle and incomplete same, two numerical value even gap are bigger in some engineering.
As shown in Figure 1, in type roof, light steel roof truss slope photovoltaic project, the structure on whole roof comprises the second cloudy roof structure 12 of first roof structure 11 and court of Chaoyang.Because the structural limitations on roof, photovoltaic module 21,22 all is to install with the structure arrangement mode that directly is affixed on the roof.It is negative angle that this mounting structure can cause on the roof angle of slope of the photovoltaic module 22 on the second cloudy roof structure 12.The generating capacity of the photovoltaic module 22 of this part will reduce greatly in this case, cause the generated energy of whole generating engineering that tangible loss is arranged.
Therefore, those skilled in the art is devoted to develop a kind of photovoltaic module that improves the type roof, light steel roof truss slope of photovoltaic module generated energy structure is set.
The utility model content
Because the above-mentioned defective of prior art, the utility model technical problem to be solved provides a kind of photovoltaic module that improves the type roof, light steel roof truss slope of photovoltaic module generated energy structure is set.
For realizing above-mentioned purpose; The utility model provides the photovoltaic module on type roof, a kind of light steel roof truss slope that structure is set; Comprise first roof structure with positive bevel angle, second roof structure with reverse caster angle; Said first roof structure is provided with first photovoltaic module, and said second roof structure is provided with second photovoltaic module; Be provided with bracing frame between said second roof structure and said second photovoltaic module, support frame as described above is a wedge.
Preferably, said wedge carves the angle more than or equal to said reverse caster angle.
Preferably, support frame as described above and said second roof structure are structure as a whole.
Preferably, support frame as described above is lightweight steel construction or brick wall structure.
Preferably, said first roof structure is a lightweight steel construction.
Preferably, said second roof structure is a lightweight steel construction.
The beneficial effect of the utility model is:
