Embodiment
As Figure 1-Figure 4, a specific embodiment of the present invention, photovoltaic generation rack mounting structure, comprise briquetting 1, matrix pad 3, purlin 4, square nut 5 and stay bolt 6, stay bolt 6 is successively through briquetting 1, purlin 4 is fixedly connected with square nut 5, briquetting 1 is coordinated with the photovoltaic module 7 of two rows respectively by the flanging of both sides, matrix pad 3 is provided with between photovoltaic module 7 and purlin 4, stay bolt 6 adopts specification to be the bolt of M8x100, because original mounting structure adopts lag bolt, do not affect the space of electric poling, first row photovoltaic module is still adopted to the fixed form of original mounting structure, to photovoltaic module overhead far away, as second, 3rd, the installation of the 4th row's assembly, then adopt new mounting structure.
The construction method of photovoltaic generation support, the steps include: the first step, civil engineering pile foundation.
Second step, tripod is assembled: before (1) tripod is assembled, first check that whether tripod material is complete, intact, that is: whether the timbering material such as front column, rear column, crossbeam, diagonal brace, diagonal brace upper connector, connecting bolt, flat shim, spring washer is complete, material has zero defect, if any lacking or defect, then completion or replacing;
(2) the tripod assembling of photovoltaic bracket: 1. crossbeam is lain in ground, front column, rear column and crossbeam are linked together by design drawing, according to design drawing size, the 8th hole alignment in front Kong Yingyu crossbeam distance end of adpting flange plate on front column, on rear column, the metapore of adpting flange plate should align with crossbeam other end distance the 11 hole, the bolt of M10 is passed down through in the groove of crossbeam, and assorts two plain washers and a spring washer, firmer nut;
2. by the bolted splice of one end of diagonal brace elder generation with the diagonal brace connecting plate M10 of rear column bottom, but it is not first fastening, also the bolt connection diagonal brace upper connector of M10 is used at the other end of diagonal brace, diagonal brace is made naturally to rotate around first pin joint again, another face of diagonal brace upper connector and the lower plane of crossbeam are contacted, and join two plain washers, a spring washer with the bolt of M10, diagonal brace upper connector and crossbeam are linked together and clamp nut, again that the bolted of the first two pin joint is good, complete the assembled of photovoltaic bracket tripod;
3. self-inspection: be 2600mm by the steel tape horizontal range measured between forward and backward column, as this size has error, then unclamp the connecting bolt of forward and backward column and crossbeam, utilize the installation elliptical aperture of crossbeam to adjust, to reach after just size each bolt firm again.
3rd step, vertical tripod: (1) three people's compounding practice, tripod is erected, front column and rear column are lifted to be put in cement pile foundation, make the pre-embedded bolt in cement pile foundation through the connecting plate installing hole of forward and backward column bottom, two people hold up steady tripod, and another people assorts plain washer, spring washer, nut, by overall for tripod firm in cement pile foundation;
(2) use angle measuring instrument, whether the angle measuring tripod crossbeam is 36 ° ± 1 °, if any deviation, then unclamp the bolt that tripod is connected with cement pile foundation, below column lower connecting plate, adopt the mode of plus-minus parallels to adjust, adjusted rear fastening good nut and again checked with upper angle.
4th step, purlin mounting and adjusting: 36 meters of submatrixs are longitudinally the purlin of 56 meters of length, the purlin of 1 6.79 meters of length, laterally total identical purlin 5 is arranged; 18 meters of submatrixs are longitudinally the purlin of 26 meters of length, the purlin of 1 6.41 meters of length, and laterally total identical purlin 5 is arranged;
(1) purlin of first row lowest part is installed, get the purlin of 6 meters of length, purlin end is made to be 681mm apart from the tripod crossbeam distance of the most end of submatrix, purlin distance crossbeam distance 70mm bottom, in each contact position of purlin and crossbeam, with hexagonal socket nut, plain washer, spring washer, purlin is connected with crossbeam and tightens together by square nut, get the purlin of 6 meters of length again, its end is docked with a upper mounted purlin, with U-shaped guide groove connector, adjacent two purlins are linked together, and purlin and each crossbeam contact point to be connected with the same method that last purlin is installed and fastening.Install according to the method successively third and fourth, five, six roots of sensation purlin, six roots of sensation purlin length is 6.79 meters, after first row purlin installs, use the same method successively install second and third, four, five row's purlins, the spacing of each row's purlin is 970mm;
(2) adjust the linearity of purlin: adopt bracing wire adjustment, as purlin linearity has deviation, the footing mounting nuts of corresponding tripod can be unclamped, make this tripod entirety movable, until wingceltis bar meets the requirements of linearity.
5th step, photovoltaic panel is installed: the installation of (1) first row photovoltaic module: after photovoltaic module is transported to installation station by the personnel of carrying, taken over by installation personnel, photovoltaic module is placed into the first row purlin place, along aliging with the first row purlin under assembly, side and purlin end distance 25mm, two aluminium alloy limit briquettings are installed at the first row purlin place, assembly is fastened solid, and equipped bolt, pad, square nut are fastening, briquetting assembly in Article 2 purlin place, the position corresponding with limit briquetting are installed, but bolt temporarily need not be fastening; With the first block assembly for benchmark, use the same method horizontal installation component successively, and the lateral clearance between assembly and assembly is 25mm.Laterally installing battery component is 22 pieces;
(2) installation of second row photovoltaic module: at the second row module position that first row first block assembly is corresponding, start second row first block assembly is installed, briquetting on assembly is middle briquetting, fastening bolt is from top to bottom through wingceltis bar, workmen carries out terminal operation at module backside, the each block assembly of second row should align with each assembly sideline of first row, the linearity after installing with Assurance component, carries out tightening operation then avoid front to install trampling phenomenon to assembly at module backside;
The installation of (3) the 3rd row's photovoltaic modulies: identical with the mounting means of second row assembly.But because setting height(from bottom) is higher, installation personnel palpus uses step to install, and installation personnel must join safety belt, to avoid security incident, simultaneously the safety of palpus Assurance component simultaneously;
The installation of (4) the 4th row's photovoltaic modulies: similar with first row assembly mounting means, the briquetting that difference is in the 5th purlin place, road is limit briquetting, it is identical that assembly is arranged in secure context and installation the 3rd.
Answer four people one group during installation, two people transfer to two installation personnels on movable Scaffold after removing assembly, submit assembly personnel should immediately at supported underneath assembly until card as in briquetting.
(5) self-inspection: after each submatrix installation, necessary self-inspection, ensure that photovoltaic bracket is respectively connected the fastening of fastening bolt with assembly, assembly linearity meets the requirements.
This embodiment shortens greatly installs the same single-row set-up time, and install more convenient, improve installation effectiveness, eliminate potential safety hazard, protect the safety of workman, reliability is high, has wide market application foreground.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technical staff in the art, all should by the determined protection range of claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
