For the photovoltaic module installation rack in Mid-low latitude area
Technical field
The present invention relates to a kind of photovoltaic module installation rack, particularly a kind of photovoltaic module installation rack for Mid-low latitude area.
Background technology
By the impact of photovoltaic overall situation, nearly 2 years large-scale photovoltaic plant projects are in rapid expansion, and the competition between enterprise grows in intensity.This wherein, the construction of photovoltaic plant also needs to consider its photovoltaic module installation rack used economy structurally, practicality and aesthetic property etc.
Existing installing rack adopts carbon steel material to make mostly, due to the hardness of carbon steel and intensity all higher, therefore its plasticity is also lower.The installing rack utilizing this carbon steel to make also all is limited to the shape manufacturing comparatively rule, as rectangle or simple bending-like, thus this kind of installing rack also can only play simple supporting role to photovoltaic module, and its stress performance is general not good, just have impact on the practicality of installing rack yet.Meanwhile, this type of installing rack due to shape be all some comparatively common shapes, therefore its aesthetic property is also generally poor.
In addition, existing installing rack is for the general installing rack under various terrain environment mostly, do not take into full account under some specific environments, the particularly problem of the setting angle of photovoltaic plant under Mid-low latitude area, difference under this different latitude band between setting angle also just will certainly have influence on the stressed effect of installing rack to photovoltaic module, therefore also can cause impact to a certain degree to the practicality of installing rack.
Therefore, we need badly and a kind ofly can ensure economy, simultaneously can improve again practicality and aesthetic property and the novel photovoltaic module installing rack in more applicable Mid-low latitude area.
Summary of the invention
Object of the present invention is exactly for the problems referred to above, provides a kind of and can ensure economy, simultaneously can improve again practicality and aesthetic property and the photovoltaic module installation rack in more applicable Mid-low latitude area.
To achieve these goals, the invention provides following technical scheme: for the photovoltaic module installation rack in Mid-low latitude area, it comprises:

Embodiment
The preferred embodiment of the present invention is described in detail below in conjunction with accompanying drawing.
Embodiment 1
The present embodiment is most preferred for implementing the utility model.As shown in Figure 1, the photovoltaic module installation rack for Mid-low latitude area in the present embodiment comprises: upper installed surface 1 and lower installed surface 2, and it is arranged in parallel; First main muscle 31 and the second main muscle 32, its to be set in parallel between installed surface 1 and lower installed surface 2 and with this on installed surface 1 and lower installed surface 2 form zigzag structure, this first main muscle 31 and the second main muscle 32 also form angle with upper installed surface 1 and lower installed surface 2 respectively, first main muscle 31 and upper installed surface 1 form the angle of 105 °, and the second main muscle 32 and lower installed surface 2 form the angle of 105 °; Three diagonal bars 4, its arranged askew becomes Z-type and is arranged between the first main muscle 31 and the second main muscle 32, and such design can make diagonal bar obtain a larger Area of bearing to photovoltaic module in side direction, promotes stressed effect; Above-mentioned upper installed surface 1, lower installed surface 2, the first main muscle 32 of main muscle 31, second and diagonal bar 4 shapingly to be made by aluminium alloy extruded.Because the plasticity of aluminium alloy is strong, therefore the present invention is taken full advantage of this plasticity and has been made the structure of this installing rack by the technique that such as hot melt extruded is shaping, in this structure, first main muscle 31 and the second main muscle 32 pairs of photovoltaic modulies define the support of vertical direction and gravity direction, three auxiliary first main muscle 31 of diagonal bar 4 and the second main muscle 32 pairs of photovoltaic modulies carry out the support of side direction, namely from the horizontal by the support on the direction of certain angle, such three diagonal bars 4 and the first main muscle 31, the cooperation of the second main muscle 32 can form the support of multiple directions to photovoltaic module, it is more excellent compared to prior art stressed effect, improve the practicality of installing rack, and buckling in extrusion modling process of installing rack can also be strengthened the adding of three diagonal bars 4, first main muscle 31 and the second main muscle 32 also form the angle of 105 ° with upper installed surface 1 and lower installed surface 2 respectively, the setting angle that the photovoltaic plant of consideration Mid-low latitude band has been set fully of this angle, through overtesting, the installing rack with this angle more adapts to the setting angle of the photovoltaic plant of Mid-low latitude band compared to prior art, stressed effect is better, practicality is stronger: as shown in Figure 2, the setting angle of support 7 is 15 °, now first of this installing rack the main muscle 31 and the second main muscle 32 are just and horizontal plane, now stressed effect is best, wherein, installing rack be by bolt 5 respectively with photovoltaic module 6, support 7 connects, as shown in Figure 3, the setting angle of support 7 is 30 °, and now first of this installing rack the main muscle 31 and the second main muscle 32 also can form preferably stressed effect, this novel profile design of photovoltaic module installation rack of the present invention, break the profile design of the rule of that installing rack of the prior art, although aluminium alloy wants high compared to carbon steel cost, but profile design of the present invention is more compact, there is no the generation of excess waste, relatively more save material, ensure that the economy of installing rack.
