The solar battery bracket that the utility model provides is by being provided with first installation portion and second installation portion at described second column, the contour setting in installation site of first end of described second installation portion and described installing rack, described first installation position is in the top of second installation portion, when second end of installing rack is positioned at first installation portion, horizontal by certain angle (being convenient to receive the inclination angle of sunlight), can make the solar panel that is installed on the installing rack fully absorb sunray; When second end of installing rack was positioned at second installation portion, parallel with horizontal plane, the suffered wind-force of solar panel that is installed on the installing rack reduced, and the power that solar bracket bears is also corresponding to be reduced.Those skilled in the art will appreciate that wind carries the computing formula of (bearing wind-force): W=C
W* q * A, wherein: q-design wind pressure; A-wind area; C
W-wind factor, in the time of with the wind, C
W=0.65+0.009 θ, in the time of against the wind, C
W=0.71+0.016 θ; θ is the angle of solar panel and horizontal plane; With the solar battery bracket in the present embodiment is example, when solar battery bracket is positioned at first state, and angle theta=45 of installing rack and solar panel of go up installing and horizontal plane °, C with the wind
W=1.06, C against the wind
W=1.43.And when solar battery bracket is positioned at second state, angle theta=0 of installing rack and solar panel of go up installing and horizontal plane °, C with the wind
W=0.65, C against the wind
W=0.71; Hence one can see that, in the time of with the wind, the wind that solar battery bracket is positioned at second state carries about 0.61 times that carries for the wind that is positioned at first state, in the time of against the wind, the wind that solar battery bracket is positioned at second state carries about 0.50 times that carries for the wind that is positioned at first state, prove absolutely that the angle of solar panel and horizontal plane is more little, its wind carries more little.
By the structural design of present embodiment, solar battery bracket is when being subjected to high wind, by making the parallel active force that can reduce high wind to the whole solar cell support with horizontal plane of installing rack.Thereby, can corresponding reduction with the design strength of described solar battery bracket, that is to say, the wind loading rating of solar bracket integral body is positioned at level design with solar panel, and during not with normal use, the maximum wind velocity when promptly solar panel and ground (being horizontal plane) is certain inclination angle designs, can reduce the material and the cost of manufacture of solar bracket, rough estimation can be saved 1/5th support cost, i.e. steel product cost; Say further, by the positioning component of solar battery bracket is stressed according to designing a little more than the common wind-force in locality, installing rack, column and locking device during with the solar panel level return period maximum wind velocity carry out wind force proofing design, when actual wind-force surpass positioning component predetermined when bearing wind-force, the shell fragment of the two port positioning component of installing rack is rotated down around first end after applying downward pressure, stop to rotate when rotating to the locating piece of second installation portion, and it is locked by the locking device of second installation portion place setting, at this moment, solar bracket can be resisted large wind, after the high wind, support can be placed first installation portion again, Stability Analysis of Structures, security insurance can satisfy the needs of fixed solar battery.
What deserves to be mentioned is, solar battery bracket of the present utility model also can comprise damping device, described damping device at second end of installing rack when first installation portion drops to second installation portion, can play the effect of buffering, damping, prevent solar bracket on the installing rack and the damage of going up the solar cell of installing thereof, the damping device that described damping device can adopt those skilled in the art to use always is not done at this and to be given unnecessary details.
In addition, be understandable that, in the present embodiment, make the contour setting in installation site (being the articulated section) of first end of described second installation portion and described installing rack, when second end of installing rack is positioned at second installation portion, parallel with horizontal plane, be a kind of preferred mode.In fact, in other embodiment of the present utility model, and do not require the contour setting of described second installation portion and described articulated section, as long as make described first installation position in the top of second installation portion, the angle of inclination of described installing rack when second state gets final product less than the angle of inclination of installing rack when first state, so just can guarantee installing rack when second state suffered wind-force less than wind-force suffered when first state.
The solar battery bracket of the utility model preferred embodiment has following characteristics: the positioning component of solar battery bracket is stressed according to designing a little more than the common wind-force in locality, installing rack, column and locking device during with the solar panel level return period maximum wind velocity carry out wind force proofing design, when the solar panel of installing on the installing rack is subjected to monsoon intensity to surpass the design load of positioning component, second crossbeam of installing rack glides after shell fragment is exerted pressure, second of installing rack is made a clean sweep of when dropping down onto horizontal level, the shell fragment of touching locking device, shell fragment contact briquetting and to move to the below of briquetting locked to realize, make solar battery bracket can resist big wind speed, and can effectively reduce material cost.
Those skilled in the art know easily; the above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.Protection range of the present utility model is determined by claims.
