The adjustable photovoltaic support in a kind of basis
The utility model relates to the mounting bracket of photovoltaic battery panel.
Common photovoltaic bracket has the versions such as ballast cribbing, concrete pedestal cribbing and spiral ground pile cribbing.The ballast cribbing is easy for installation, need to level land, and is not suitable for the soft area of soil property; Concrete pedestal cribbing underlying strength is good, and applicable geological conditions scope is wider, but the concrete pedestal construction period is relatively long, is subject to the restriction of season and temperature; Spiral ground pile cribbing easy construction, but pile installs and limited by local geological conditions, is not suitable for the hard area of soil property, and since pile be embedded in underground, outstanding at the varieties in saline-alkali areas Anticorrosion.
In the installing bracket of solar cell module patent that has retrieved, " solar photovoltaic cell panel mounting bracket " (patent No.: ZL200920298183.4) be the ballast cribbing, higher to ground flat degree and compaction requirement, be not suitable for the soft desert electric field of soil property; " 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; " 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, 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.
Domestic photovoltaic bracket producer must believe, like the companies such as Li De such as peace, adopt generally that the long limit of battery component is vertically arranged, C shape steel is opening up and aluminium alloy in the scheme of briquetting and side pressing block securing battery cell packs, the battery component connection reliability is poor, C shaped steel accumulates rainwater and the dust storm technological deficiency such as easily get rusty, briquetting is fixed on the cell panel surface, easily cause shade, be not easy to the mechanized cleaning battery component.

At upper bracket at least five loss of weight mounting holes are set, the installation passage that matches with the loss of weight mounting hole in the respective side setting of front support beam and rear support beam.
Described front support beam and rear support beam are the C formed steel construction, and upper bracket is fixedly connected with square nut by bolt with front support beam, rear support beam.
Described square nut bottom arranges mating groove, the chimb interlock of mating groove and front support beam, rear support beam; And on the mating groove with the friction line.
Described crossbeam is connected with upper bracket by U bolt, clamp nut.
Leave 2～6mm gap between the adjacent beams.
Crossbeam is connected with cant beam by pipe clamp.
Between adjacent front support beam, perhaps arranged crosswise reinforcing bar between the adjacent rear support beam.
Bar shaped or block cement buttress are set below undersetting and upper bracket, and the cement buttress is placed directly on the fabricating yard or is pre-buried to underground.
Adopt the utility model of technique scheme, foundation construction is convenient, and is quick for installation, safeguards easy to usely, and construction cost is low.The utility model is applicable to outdoor large Gobi Desert Terrain ground light overhead utility, also is applicable to roof photovoltaic power station.Progressive is:
(1) the photovoltaic bracket basis is adjustable, and basic required precision is low; Foundation construction is convenient, does not need extensive smooth location, need not to excavate ground; Concrete pedestal intensity is good, strong adaptability.
(2) quick for installation, whole process to be installed to need not welding, part generalization degree is high, and shaped steel and steel pipe all need not perforate, do not have perforate and alignment error problem, can random overlap joint be set according to the place; Job safety need not work high above the ground, need not auxiliary equipment.
(3) connect reliably, solar module is fixedly connected with by 4 of Z-shaped solar module connecting plates with cant beam, cant beam is that aspectant contact is connected with the solar module frame, connecting plate and solar module " binding ", the fixing reliably while is the ingenious rigidity of utilizing the solar module frame to strengthen photovoltaic bracket again.
(4) maintenance is easy to use, and every solar module all can independently be installed, and repair demolition is convenient, can not affect other solar module; Photovoltaic bracket draining in rainy season is unobstructed, adopts the opening down or slant setting design of crossbeam, seeping phenomenon and then corrosion zinc coat can not occur; Solar module connecting plate Hide All is at the solar module back side, and whole row's solar module surface is beneficial to solar module and carries out the mechanized cleaning maintenance neatly without thrust.
