Abstract

The invention discloses a bracket for a photovoltaic power station. The bracket mainly comprises three parts, including rigid purlines, supporting rods and inhaul cables, wherein the rigid purlines are erected on stand columns, and directly connected with a photovoltaic module for supporting the photovoltaic module; the supporting rods are arranged between the rigid purlines and the inhaul cables for connecting the rigid purlines and the inhaul cables together; pre-stressing force is applied to the inhaul cables to reduce deflection of the rigid purlines and to bear force transmitted from the supporting rods; and the rigid purlines, the supporting rods and the inhaul cables can be optionally combined. The bracket has high applicability and can be applied to regions where a large number of bracket stand columns cannot be reduced and relatively high span is needed; the bracket is convenient to assemble, flexible to configure, and low in damage to the ground; the installation mode of the photovoltaic module is the same as that of a conventional bracket; and compared with the conventional bracket, the bracket provided by the invention is more environment-friendly, lower in bracket steel consumption, and lower in construction cost.

Description

A kind of support for photovoltaic plant

Technical field

The present invention relates to the support technology field of photovoltaic plant, it is specifically related to a kind of support for photovoltaic plant.

Background technology

In photovoltaic plant engineering, the pile foundation engineering of support and installing engineering are whole photovoltaic plant civil engineering and electromechanical engineering Amount the best part.Conventional photovoltaic bracket, typically takes door type steel frame structure, by upright supports cant beam, then oblique at present Mounting purlines on beam, installation photovoltaic component on purlin.It is reliable that the method has a connection, using the advantage 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. Shortcoming.Further, since column spacing is usually 3m, traditional photovoltaic bracket due to post away from less it is impossible to solve large span Problem.

Occur in that flexible photovoltaic support in recent years, due to rope bending rigidity very little, deformation is big, to load, uneven The dynamic load such as distributed load and wind is more sensitive.In actual use, swinging up and down of assembly easily causes inside Hidden split or hidden split extension, thus causing the Latent destruction of assembly.

Content of the invention

It is an object of the invention to provide a kind of photovoltaic bracket, both can solve the problems, such as that conventional photovoltaic support span was little, Can solve the problems, such as that flexible photovoltaic stiffness of support is little, the installation side of the mounting means of its photovoltaic module and conventional photovoltaic assembly again Formula is identical.

The technical scheme is that:

A kind of support for photovoltaic plant, provides, in the added photovoltaic module that is set to of column, the rigid purlin supporting, 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 connected by strut.

Further, described a kind of support for photovoltaic plant, mainly by rigid purlin, strut and drag-line three It is grouped into;Described rigid purlin is erected on column, is joined directly together with photovoltaic module, is that photovoltaic module provides a supporting role;Institute State strut to be arranged between described rigid purlin and drag-line, for coupling together rigid purlin and drag-line;Apply on described drag-line Added with prestressing force, for reducing the amount of deflection of rigid purlin, bear the power that described strut transmits, described rigid purlin, strut and draw This three part of rope can be in any combination.

Further, in such scheme, between described strut and rigid purlin, and the connection between strut and drag-line Mode is rubber bound, and concrete method of attachment is:

Step one:On the surface of described strut and rigid purlin junction, and the surface of strut and drag-line junction is equal Coat rubber heat cure adhesive coating, dry, precuring, control build is 13.5-20 micron;

Step 2:Isolating pad is compressed 15%, is placed in and scribbles rubber heat cure adhesive coating on strut and rigid purlin Centre, and the centre of rubber heat cure adhesive coating is scribbled on strut and drag-line, heating makes isolating pad and the hot sulfur of rubber Change binding agent and produce heat cure bonding.

Further, described isolating pad is curing rubber.

Further, described rubber heat cure binding agent is Cilbond80C.

Further, in such scheme, described drying process condition is:30-35 minute is dried under room temperature, or 65-68 DEG C force drying 5 minutes.If drying is insufficient after gluing, dissolvent residual can be led in glued membrane, when cured during bonding, can rush Broken glued membrane, causes degumming.

Further, described pre-cure process condition is:155-157 DEG C carries out precuring, and the time is less than 12 minutes.

Further, on the surface of described strut and rigid purlin junction, and the surface of strut and drag-line junction Before all coating rubber heat cure adhesive coating, need coating surface is surface-treated with sand-blast, from 200-400 The quartz sand of micron grain size or aluminium oxide carry out blasting treatment, and to avoid various pollutant residuals, these pollutant can be to bonding Cause extreme influence, lead to degumming.It is also possible to use other surfaces processing method, such as phosphatization and chromate treating, acid-alkali treatment, and Chemical reagent is processed.

Compared with photovoltaic bracket form of the prior art, beneficial effects of the present invention are embodied in:

(1) there is wide applicability, can be used for that inconvenience is a large amount of to reduce bracket upright post it is desirable to the larger region of span;(2) Easy to assembly, the mounting means of photovoltaic module is identical with conventional stent;(3) flexible arrangement;(4) little to ground failure, with respect to Conventional stent is more environmentally friendly;(5) little with respect to conventional photovoltaic support steel using amount, low cost.
