Description
Technical field
The present invention relates to a kind of driving mechanism of oblique single shaft photovoltaic tracking support.Specifically, a kind of cable for photovoltaic tracking support-semi-circular guide groove driving mechanism is related to.
Background technology
Along with the sustained and rapid development of China's economic, energy resource consumption and environmental problem more and more become the significant problem that people pay close attention to.Coal, oil, the conventional energy resource such as natural all belong to non-renewable resources, and quantity reduces day by day, and the discharge of " three wastes " causes increasing environmental pollution, the important content developing into current social development of new forms of energy.Solar energy has been widely used in the fields such as generating, heating as a kind of inexhaustible clean energy resource, and solar energy generation technology is increasingly mature, cost reduces gradually, add the encouragement of national policy, and photovoltaic plant emerges rapidly.
Typical single shaft photovoltaic tracking mounting system provides the fixed support of support coming from basis to form by one piece for the swinging mounting with two bearings of fixing photovoltaic battery panel with for these two bearings.Swinging mounting is maximum by the generating total amount realizing all cell panels fixing on this swinging mounting in certain hour scope around the swing of these two bearings.Here swing, normally different latitude, the function of solar orbit during different solar terms.Driving shaft through these two bearings provides the moment of torsion of rotation for swinging mounting.And the moment of torsion of driving shaft comes from reductor or linkage.
The essential characteristic of above-mentioned Drive Structure is driving shaft transmitting torque.As everyone knows, photovoltaic cell board mount will bear stronger wind and carry active force, usually large more than 13 grades of design, and therefore, gear reduction unit and driving are taken out and must be born a lot of moment of torsion.Here very high pulling torque refers to, the reductor under Financial cost and the intensity of driving shaft cannot ensure that resisting this larger wind carries.In other words: the driving shaft diameter of axle and the reducer gear modulus that meet resistance 13 grades of wind-force, its cost has exceeded owner can bear the upper limit; And meet the driving shaft diameter of axle that owner's cost expects and module and can not ensure to carry reductor under effect and driving shaft reliability at design wind.Find one can meet owner's cost requirement, reliably can resist again the brand-new mechanism that 14 grades of wind carry becomes object of the present invention.
Utility model content
Sail is best suited for bearing wind and carries the most successful ancient machinery of effect.The present invention uses for reference the principle of sail, proposes one and utilizes cable pull to provide power, and utilize semi-circular guide groove to realize photovoltaic cell board component that cable travel is directly proportional to rotation angle swings driving mechanism.Described technical scheme is as follows:
For cable-semi-circular guide groove driving mechanism of photovoltaic tracking support, it is characterized in that mainly comprising semi-circular guide groove 1, left tractive cable 2, right tractive cable 3, left chain wheel assembly 4, right pulley assembly 5, swinging mounting 6 and fixed support 7 form.Described semi-circular guide groove 1 is the semi arch structure that a radius is as far as possible large; Its cross section is " U " groove being conducive to engaging cable; In order to improve the rigidity of semi-circular guide groove, some brace rod structures can be set in the inner side of semi arch.
Described semi-circular guide groove 1 center overlaps with the pivot of swinging mounting 6, for being rigidly connected between semi-circular guide groove 1 and swinging mounting 6, and semi-circular guide groove 1 place plane and swinging mounting 6 place plane orthogonal.
Described left tractive cable 3, one end of right tractive cable 4 is articulated in semi-circular guide groove 1 and swinging mounting 6 junction respectively, engages respectively after the other end of two tractive cables walks around the arc circle section of in semi-circular guide groove 1 with the left chain wheel assembly 4 be fixed on fixed support 7 and right pulley assembly 5.Described left chain wheel assembly 4 and right pulley assembly 5 are fixed on fixed support 7, and the axis of rotation of left chain wheel assembly 4 and right pulley assembly 5 is parallel with described semi-circular guide groove 1 axis of oscillation, and the midship section of this two pulley assembly overlaps with the midship section of semi-circular guide groove 1.The layout of this two pulley assembly is for ensureing that tractive cable enters " U " type groove of semi-circular guide groove 1, and the maximum engagement length of every side cable is all greater than the arc length corresponding to swinging mounting maximum pendulum angle; For improving the rigidity of semi-circular guide groove 1 further, " U " groove of left chain wheel assembly 4 and right pulley assembly 5 also carries out having engaged with " U " type groove of semi-circular guide groove 1.
Described tractive cable is arranged along the internal tangent of left chain wheel assembly 4 and right pulley assembly 5 and semi-circular guide groove 1 all the time, ensure that the angle of oscillation speed of the linear velocity of tractive cable and swinging mounting is linear.
The present invention's beneficial effect compared with prior art:
Cable-semi-circular guide groove driving mechanism for photovoltaic tracking support have employed a major diameter semi-circular guide groove, increases the driving arm of force, reduces actuating force; When tractive cable actuating force is certain, greatly strengthen the torque of swinging mounting wobble drive.Due to the driving shaft of transmitting torque abandoned and complicated reductor, enormously simplify driving mechanism, greatly reduce the stress of any parts in mechanism, thus greatly improve the intensity of system, and then improve the reliability of following the tracks of mounting system.Tractive cable has intrinsic flexible nature, greatly strengthens the overall wind load resistance ability of mounting system.The actuating speed of tractive cable and the linear relationship of swinging mounting angle of oscillation speed, make the drived control function of tractive cable greatly simplify, and then reduce manufacturing cost.
