Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail:
Referring to Fig. 1-3, solar automatic tracking device of the present invention, comprises the bone joint physical construction 6 being arranged on base, and the top movable end of bone joint physical construction 6 is provided with link 7, and the load that need to gather sunshine is installed on link 7; All sides of link 7 are furnished with some sealing air cylinders 4 that are vertically fixed on base, and the movable end of sealing air cylinder 4 is connected with the downside of link 7 by articulation mechanism; Be provided with the sunray focus type reflecting curved surface 5 of high reflectance at the rear side of some sealing air cylinders 4.Described reflecting curved surface 5 is parabolic cylinder shape in the vertical direction.
Sealing air cylinder 4 of the present invention is made up of the column cylinder body of a sealing and the axis of the piston that column cylinder body one end is set, gassy in column cylinder body.Some sealing air cylinders 4 are all upside down on base, and its axis of the piston 4.1 is fixed on base, and its cylinder body 4.2 is connected by turning joint mechanism with the downside of link 7.Described articulation mechanism comprises that the level being fixedly installed on respectively on link 7 and sealing air cylinder 4 is to power arm, and two levels connect by roller between power arm.
Solar automatic tracking device of the present invention is applicable to any needs all the time towards the load of sun collection sunshine, and what Fig. 1-3 provided is a kind of specific embodiment of the present invention, and the load in figure is made up of dish-shaped reflection concentration type body 1 and dimmer 2; Dish reflection concentration type body 1 is fixedly installed on link 7, directly over dish-shaped reflection concentration type body 1, by dowel 3, dimmer 2 is corresponding thereto set, and is provided with the optical channel of hollow out in the center of dish-shaped reflection concentration type body 1.The dish-shaped reflection concentration type body 1 being oppositely arranged and the coincidence of the primary optical axis of dimmer 2 and focus are identical.
In sum, the present invention wherein a kind of embodiment forms load by dish-shaped reflection concentration type body 1 and dimmer 2, multiple sealing air cylinders 4 of being answered in contrast by the sunray focus type reflecting curved surface 5 of high reflectance form heated body group, and require bone joint physical construction to have the function that three-dimensional freely rotates.The reflective parabolic sphere of dish condensing body 1 and dimmer 2 curved surfaces as load will have same focus, identical optical axis, but both focal length differences, its function is under the driving control of heated body group (also can be described as three dimensions solar automatic tracking system), the optical axis of load keeps the state parallel with sunshine always, realizing parallel sunshine by the reflecting surface of the reflective parabolic sphere of dish condensing body 1 converges after enhancing, again according to the reciprocity principle of light path by same focus and there is the dimmer 2(minute surface of same optical axis) be adjusted to again the parallel sunshine of enhancement mode, and hollow out delivery outlet (being optical channel) along optical axis from the reflective parabolic sphere of dish condensing body 1 center penetrates, and the heated body group that the sunshine reflecting curved surface 5 of high reflectance and multiple sealing air cylinders 4 of answering in contrast form settles institute to form according to particular spatial location, can the be disposable integrated functions such as signals collecting, power drive and transmission in motion tracking sunshine system that complete, utilize parabolic cylinder reflecting surface that the sunshine in this moment is converged and reflexed on corresponding sealing air cylinder 4, the heat producing will cause the expanded by heating of sealing gas, again because the sealing gas in the cylinder body of sealing air cylinder 4 is metal cylinder shape, other direction shape immobilizes, so only can realize by the directed movement of piston the new balance of pressure, produce corresponding thrust, promote the directed movement of piston rod, and here the diameter at piston place than little many of heated portion, object is to need the displacement of larger distance and the actual needs of smaller thrust here, and this directed movement by the roller of power arm and top ends apply strength upwards condensing body is moved upward produce to tilt to ensure its normal and sunshine direction basically identical, along with sun motion from east to west, the direction of sunray is also producing respective change continuously, thereby along with passage of time is successively heated A successively in different time sections, B, C, each seals heated body D etc. (being set to P in Fig. 2), and the corresponding movement along with sunshine, A, B, C, the sealing air cylinders such as D again successively successively order because different time sections lose converge reflected sunlight irradiation and naturally after cooling shrinkage piston rod is bounced back, and naturally fall after rise under load Action of Gravity Field, thereby form along with sunshine is by the variation successively of direction of illumination westwards again of east orientation south, dish reflection concentration type body 1 cross section also corresponding generation towards by the rotation (motion) westwards again of east orientation south, thereby realize condensing body from motion tracking solar light irradiation direction function, realize and receive to greatest extent sunshine effect, the precondition that certain dish-shaped reflection concentration type body 1 produces these motions necessarily require whole load in dish-shaped reflection concentration type body 1 center as rotation axis, the mode that is slidably connected that forms any direction with bone articulated manner at the strong point here is just connected and can realizes with physical construction.The alleged bone joint physical construction of the present invention is goalpost joint linkage structure, has the ability of multiple-directional rotating.
In specific embodiments of the invention, be not limited only to structure shown in Fig. 1-3, load of the present invention also can need to gather for being arranged on solar energy photovoltaic panel on link 7 or other carrier of sunshine.
