- 9 are please referred to Fig.1, the utility model provides a kind of uniaxial sun tracker, including more root posts 1；Each column top
Portion is provided with a swing rod 2, these swing rods are mutually parallel and can be rotated at the top of corresponding column on vertical plane；Swing rod
Along more support beams 3 are vertically provided with the direction of swing rod, these support beam upper surfaces are equipped with solar energy electroplax 4 for upper surface；
Further include one and is rotationally threaded through the transmission shaft 5 so on column 1, and the motor 6 for driving transmission shaft 5 to rotate；
The position for being located at 2 lower section of every swing rod on transmission shaft is respectively provided with there are one reel 7, and coiling has two steel in opposite direction on reel
The bottom both ends of cord 8, every swing rod are each provided with a fixed pulley 9, and the end of two steel wire ropes 8 bypasses two and slides calmly respectively
It is fixed on column 1 after wheel 9.
When work, rotated with movable reel 7 by transmission shaft 5, to be carried out at the same time winding respectively to two steel wire ropes 8, put
Volume, and then drag all swing rods 2 and rotate synchronously, reach solar tracking purpose, and since fixed pulley 9 is fixed on swing rod both ends, driving force
The arm of force it is larger, rotated so as to reliably drag all swing rods by smaller pulling force, thus without complicated more
Grade transmission mechanism, it is simple in structure；When by wind-force, the torque generated by the pulling force of steel wire rope is balanced into the torque of wind-force,
Only by shearing force at the shaft of swing rod, therefore will not be excessive and destroy because of torque is born, wind loading rating is stronger.The present embodiment
In, support beam is c-type aluminum alloy beams, to reduce weight.
Specifically, seeing Fig. 1,4,7, the swing rod 2 includes that two C-type beams 2.1 disposed in parallel and two are separately connected
Spacer block 2.2 between the end of two C-type beams；The wing plate of two C-type beams is disposed opposite to each other, and one is provided between their web
Root shaft 2.3, the shaft 2.3 are threaded through in the first bearing 1.1 for being set to 1 top of column；Two fixed pulleys 9 of swing rod 2 divide
It is not fixed on two 2.2 bottoms of spacer block.The swing rod intensity of the structure is larger and weight is smaller, and fixed pulley is arranged at spacer block,
Structural strength is larger herein, can effectively bear the power transmitted on fixed pulley.In order to further mitigate weight and rotary inertia, institute
It can be hollow structure to state spacer block, as shown in the figure.
Further, the transmission shaft 5 is square bar；The reel 7 coaxially offers the square hole being adapted with the square bar,
Transmission shaft is threaded through in square hole, to prevent reel from skidding on transmission shaft.
As shown in figure 8, the reel 7 includes two coiling portions 7.1 for being symmetricly set on 1 both sides of column, and connection two
The cylindrical portion 7.2 in a coiling portion；Cylindrical portion 7.2 is rotationally threaded through by second bearing 7.3 on column 1.In this way, on reel
The shearing force being subject to all is born by column, will not be transferred on transmission shaft 2, therefore moment of flexure will not be generated on transmission shaft, is protected
Demonstrate,proved transmission shaft only by torque, prevent transmission shaft because reel power and flexural deformation.Herein, in order to facilitate the assembly and disassembly of reel 7,
It is arranged independently of each other between the cylindrical portion 7.2 and two coiling portions 7.1, coiling portion is keyed with cylindrical portion；Or wherein one
A coiling portion is wholely set with cylindrical portion, another coiling portion is independently arranged and is keyed with cylindrical portion.
Further, two fixed pulleys 9 of swing rod 2 are separately positioned on the both sides in the longitudinally asymmetric face of swing rod, as shown in fig. 7,
To reduce the angle of the rotational plane of steel wire rope and swing rod, to reduce steel wire rope perpendicular to the rotational plane direction of swing rod
Component prevents column torsional deflection to reduce the torque that column is subject to.
Preferably, the column 1 is I-beam, and the second bearing 7.3 is mounted on the endoporus of one piece of cyclic annular mounting plate 7.4
In, which is fixed on the web of column 1, offers on the web of column and is adapted with 7.3 endoporus of second bearing
Via 1.2.The ring-type mounting plate can be, but not limited to connect by the web of bolt and column.It can be protected using work beam
Intensity is demonstrate,proved, weight also can be further mitigated；And second bearing is fixed by cyclic annular mounting plate, the web for solving column is too thin
The problem of second bearing can not effectively be fixed.
