A kind of dip-adjustable type photovoltaic bracket
The utility model relates to a kind of mounting bracket, relates in particular to a kind of mounting bracket of solar module, belongs to the solar energy generation technology field.
Common photovoltaic bracket mainly is concrete pedestal support and spiral ground pile base rack both at home and abroad, two row bases before and after mostly adopting, the basis span is generally 2～3m, cause basic One's name is legion, basis quantity too much not only increases the support cost, prolongs construction period, but also because the numerous upper component quantity that cause in basis are many, positioning accuracy is poor, and the on-site installation work amount is large.
In the installing bracket of solar cell module patent that has retrieved, " stent structure for photovoltaic module " (patent No.: ZL201120001495.1) adopt long narrow shape isolated footing to control concrete amount, but it is unreliable to exist column to be connected with steel pipe, support adopts angle steel to cause cost higher in a large number, and the technological deficiencies such as labour intensity is large are installed; " a kind of photovoltaic module mounting bracket system and fastening clamping block member thereof " (patent No.: ZL201110138059.3) adopt a kind of aluminium alloy fastening clamping block member with tooth-shape structure to fix cell panel, cost is higher, inconvenience is installed, column and longeron junction adopt EPDM rubber to regulate support angle as bolster, exist ageing of rubber to lose efficacy and cause the hidden danger of support torsional deformation; " photovoltaic component fixing bracket that a kind of U-bolt connects " (patent No.: ZL201110077646.6) be the concrete pedestal cribbing, although purlin does not exist perforate and alignment error problem, but cross-arm needs perforate and has the alignment error problem, the bracket basis height is unadjustable, and applicability is relatively poor.
Summary of the invention
The utility model provides a kind of dip-adjustable type photovoltaic bracket for the weak point of existing photovoltaic bracket, and entire body adopts the Z bar IPN to form, can the realization level install, foundation construction is convenient, and installation workload is little, the support inclination angle is adjustable, safeguard easy to use, build and cost of investment low.
For achieving the above object, the utility model is by the following technical solutions:
A kind of dip-adjustable type photovoltaic bracket, it comprises crossbeam and the cant beam between crossbeam; The cant beam below connects channel-section steel, and the channel-section steel below is connected I-steel by the waist-shaped hole I with the bolt I; I-steel is fixed on the bracket basis; Side at described I-steel arranges angle steel, and angle steel one end is hinged on the bracket basis, and the angle steel other end is connected on the cant beam with the bolt II by the waist-shaped hole II.
Described crossbeam and cant beam are Z-shape steel, have the Z-type hole at the sidewall of cant beam, and crossbeam passes the Z-type hole.
Junction at crossbeam and cant beam IPN arranges the right angle stator.
The end of I-steel arranges the waist-shaped hole III, and the waist-shaped hole III is fixed on the bracket basis by the bolt III.
Described bracket basis is prefabricated pile, bored concrete pile, piling bar or bar shaped or block concrete pedestal.
Below described bolt I, bolt II and bolt III, anti-skid washer is set all.
Adopt the positive progressive of photovoltaic bracket of the present utility model to be:
(1) delicate structure, entire body adopt the Z bar IPN to form, and connect reliably, and steel using amount is few, and cost is low, and installation workload is little.
(2) basic span is large, and the foundation construction amount is little, and easy construction does not need extensive smooth location.
(3) can realize the support level installation, it is low that labour intensity is installed.
(4) the support inclination angle is adjustable, improves energy output, reduces the power station cost of investment.
(5) connect reliably, crossbeam is that aspectant contact is connected with the solar module frame, and the fixing reliably while is the ingenious rigidity of utilizing the solar module frame to strengthen photovoltaic bracket again.
(6) maintenance is easy to use, and every solar module all can independently be installed, and repair demolition is convenient; Whole row's solar module surface is beneficial to solar module and carries out the mechanized cleaning maintenance neatly without thrust.

Such as Fig. 1～shown in Figure 6, a kind of dip-adjustable type photovoltaic bracket, it comprises crossbeam 1 and the cant beam 2 between crossbeam.Above-mentioned crossbeam 1 and cant beam 2 are Z-shape steel, have the Z-type hole at the sidewall of cant beam 2, and crossbeam 1 passes the Z-type hole, thereby form the interpenetrating structure of crossbeam 1 and cant beam 2.Junction at crossbeam 1 and cant beam 2 IPNs arranges right angle stator 6, locks with screw 11 on the stator 6.In addition as shown in Figure 5, crossbeam 1 top has mounting hole, can adjust installation site, solar module 13 left and right sides.
As shown in Figure 4, cant beam 2 belows connect channel-section steel 3, and being connected with the bolt I by the waist-shaped hole I and connecting I-steel 4 in channel-section steel 3 belows, like this, can adjust the up and down installation site of channel-section steel 3.
As described in Figure 6, in a side of I-steel 4 angle steel 5 is set, angle steel 5 one ends are hinged on the bracket basis 12, and angle steel 5 other ends are connected on the cant beam 2 with the bolt II by the waist-shaped hole II.Can realize the many grades of adjustings in support inclination angle by adjusting the installation site of angle steel 5 on cant beam 2 like this, improve energy output; In addition, bracket basis also can the realization level be installed, and reduces labour intensity is installed, and avoids work high above the ground dangerous.
Have the mounting hole III on the end of I-steel 4, on bracket basis 12, bolt III 9 can be set simultaneously, thereby can adjust installation site, I-steel 4 front and back, I-steel 4 is securely fixed on the bracket basis 12.Above-mentioned bracket basis 12 is prefabricated pile, bored concrete pile, piling bar or bar shaped or block concrete pedestal.
Below bolt I 10, bolt II and bolt III 9 anti-skid washer 7 is set all, anti-skid washer 7 after applying certain prestressing force, can prevent that I-steel from sliding along the waist hole for to widen packing ring.
