Description
Technical field
The present invention relates to the support technology fields of photovoltaic plant, are specifically related to a kind of bracket for photovoltaic plant.
Background technique
In photovoltaic plant engineering, the pile foundation engineering of bracket and installing engineering are entire photovoltaic plant civil engineering and electromechanical engineering
Measure the best part.Conventional photovoltaic bracket at present, generally takes door type steel frame structure, by upright supports cant beam, then oblique
Mounting purlines on beam, the installation photovoltaic component on purlin.This method has connection reliable, using the advantages such as generally, but there is also
Civil engineering pile foundation is more, wants the original ground vegetation of considerable damage during pile foundation construction, and construction work amount is big, and steel using amount is big etc.
Disadvantage.Further, since column spacing is usually 3m or so, traditional photovoltaic bracket can not solve large span since column is away from smaller
The problem of.
Occurs flexible photovoltaic bracket in recent years, due to rope bending stiffness very little, deformation is big, to load, unevenly
The dynamic loads such as distributed load and wind are more sensitive.In actual use, swinging up and down for component be easy to cause inside
Crack or crack extend, to cause the Latent destruction of component.
Summary of the invention
The purpose of the present invention is to provide a kind of photovoltaic brackets, both can solve the small problem of conventional photovoltaic bracket span,
It can solve the small problem of flexible photovoltaic stiffness of support, the mounting means of photovoltaic module and the installation side of conventional photovoltaic component again
Formula is identical.
The technical scheme is that
A kind of bracket for photovoltaic plant is set as photovoltaic module in column restocking and provides the rigid purlin of support, big
While amount reduces column, reduce the amount of deflection of rigid purlin by being applied with prestressed drag-line, rigid purlin and drag-line it
Between pass through strut connect.
Further, a kind of bracket for photovoltaic plant, mainly by rigid purlin, strut and drag-line three
It is grouped as；The rigidity purlin is erected on column, is connected directly with photovoltaic module, is provided a supporting role for photovoltaic module；Institute
Strut setting is stated between the rigid purlin and drag-line, for connecting rigid purlin with drag-line；It is applied on the drag-line
The power that the strut transmits, the rigidity purlin, strut and drawing are born for reducing the amount of deflection of rigid purlin added with prestressing force
This three parts of rope can be in any combination.
Further, in the above scheme, between the strut and rigid purlin and the connection between strut and drag-line
Mode is rubber bound, specific connection method are as follows:
Step 1: the surface in the surface of the strut and rigid purlin junction and strut and drag-line junction is equal
Rubber heat cure adhesive coating, dry, precuring are coated, control thickness of dry film is 13.5-20 microns；
Step 2: compressing 15% for isolating pad, is placed on strut and rigid purlin and is coated with rubber heat cure adhesive coating
Centre and strut and drag-line on be coated with the centre of rubber heat cure adhesive coating, heating makes isolating pad and the hot sulphur of rubber
Change adhesive and generates heat cure bonding.
Further, the isolating pad is curing rubber.
Further, the rubber heat cure adhesive is Cilbond80C.
Further, in the above scheme, the drying process condition are as follows: dry 30-35 minutes or 65-68 at room temperature
DEG C force drying 5 minutes.If drying is insufficient after gluing, it will lead to dissolvent residual in glue film, when being bonded when cured, can rush
Broken glue film, causes degumming.
Further, the pre-cure process condition are as follows: 155-157 DEG C of progress precuring, time are no more than 12 minutes.
Further, on the surface of the strut and rigid purlin junction and the surface of strut and drag-line junction
It before coating rubber heat cure adhesive coating, needs to be surface-treated coating surface with sand-blast, selects 200-400
The quartz sand or aluminium oxide of micron grain size carry out blasting treatment, and to avoid various pollutants residual, these pollutants can be to bonding
Extreme influence is caused, degumming is caused.Other surfaces processing method also can be used, if phosphatization and chromaking are handled, soda acid processing, and
Chemical reagent processing.
Compared with photovoltaic bracket form in the prior art, the beneficial effects of the present invention are embodied in:
(1) there is wide applicability, can be used for inconvenience and largely reduce bracket upright post, it is desirable that the biggish region of span；(2)
Easy to assembly, the mounting means of photovoltaic module is identical as conventional stent；(3) flexible arrangement；(4) small to ground failure, relative to
Conventional stent is more environmentally friendly；(5) small relative to conventional photovoltaic bracket steel using amount, low cost.
