Description
Technical Field
The invention belongs to the technical field of solar lighting devices, and particularly relates to a distributed solar lighting array linkage tracking mechanism.
Background
The ground plane coordinate system describes the spatial position of sunlight by adopting an altitude angle and an azimuth angle. The general east-west position is described by azimuth, commonly called lateral axial, and the north-south position is described by elevation, commonly called longitudinal axial. It is known that a lighting device has an important structural parameter, which is the plane enclosed by the structural dimensions of the opening of the lighting device, commonly referred to as the light entrance plane. The incident surface has a common normal. It is obvious that the daylighting device can receive the sunlight maximally when the common normal line of the daylighting device is parallel to the sunlight at any time. Achieving this requirement requires accurate mechanical mechanism dynamic tracking. The method for tracking sunlight is sunlight tracking. The movement locus of sunlight is a curve. Therefore, when a curved track is synthesized by using a planar track, the motion needs to be performed in both the east-west direction and the north-south direction. Commonly referred to as "dual axis tracking", or "full tracking". It is clear that these daylighting devices, in any form, need to fully track sunlight to maximize their daylighting area efficiency.
The methods currently used mainly present two important drawbacks:
first, a double-motor driven, double-axis tracking lighting method is used for a single lighting device. Each daylighting requires 2 drive motors. When multiple daylighting devices form a distributed daylighting array, motors with the number 2 times that of the daylighting devices are required to drive, and the daylighting devices form a large array. Too many driving motors cause too much system investment and too high cost.
Secondly, for the vertical axis or horizontal axis trough condenser, a plurality of daylighting devices can be synchronously tracked in a single-axis linkage manner, but the problem of double-axis linkage tracking is not solved. When the sunlight is tracked by a single shaft, the utilization rate of the area of an incident surface is only about 50 percent. Therefore, the light condensing efficiency of the light condenser is greatly reduced, and the market popularization and utilization of products are seriously restricted.
In order to improve the prior art, long-term research has been conducted and various solutions have been proposed. For example, chinese patent document discloses a lighting device capable of automatically tracking light rays [ application No.: CN201410660904.7], which comprises a lighting device body and a control circuit, wherein the lighting device body comprises a support base, two mechanical arms, four steering engines, a light intensity sensor, a mirror bracket and a mirror surface, and the control circuit comprises a single chip microcomputer, four steering engine driving circuits and a signal amplifying circuit.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Only one drive motor 6 is driven as a single power source and outputs two torque components to generate two motion components according to the tracking requirement. The driving motor 6 outputs a circular motion component through the second clutch 13, the axial tracking bevel gear 11, the transverse axial tracking walking gear 12 and the fixed gear 7. The other is that the driving motor 6 outputs a variable speed tangential output linear motion component through the first clutch 10, the longitudinal axis walking rack 8 and the longitudinal axis tracking gear 9. The two motion components respectively correspond to different tracking requirements of the lighting device in two angle directions, and the requirement of the lighting device array for tracking sunlight in a double-axial linkage manner is met. The sunlight collector is suitable for tracking sunlight by various sunlight collectors of different types.
The first clutch transmission structure comprises a longitudinal axial walking rack 8, one end of the longitudinal axial walking rack 8 is connected with the longitudinal axial tracking walking block 4, the longitudinal axial walking rack 8 is meshed with a longitudinal axial tracking gear 9, and the longitudinal axial tracking gear 9 is connected with the driving motor 6 through a first clutch 10. The output of the variable speed tangential output linear motion component is completed by the longitudinal axial walking rack 8, and the first clutch 10, the longitudinal axial tracking gear 9 and the longitudinal axial walking rack 8 are sequentially and mechanically connected. One end of the longitudinal axial walking rack 8 is rigidly connected with the longitudinal axial tracking walking block 4. When the longitudinal tracking gear 9 rotates, the longitudinal tracking rack 8 is forced to move linearly, and the longitudinal tracking block 4 is driven to move linearly along the sliding groove 17. The longitudinal axial tracking walking block 4 can drive the whole light-gathering array through the hinge shaft 20 and the linkage driving rod group to synchronously track sunlight in the longitudinal axial direction.
The speed change drive outputs a rotating force to drive the longitudinal axial walking rack 8 to do linear movement, and the longitudinal axial walking rack 8 pulls the longitudinal axial tracking walking block 4 to do synchronous equidirectional equipotential movement along with the longitudinal axial walking rack 8 under the positioning and orienting action of the sliding shaft 18 and the sliding groove 17. Meanwhile, the hinge shaft 20 arranged on the longitudinal axial tracking walking block 4 pushes the longitudinal axial tracking push rod 3 to do plane swing, and the hinge shaft 20 makes curvilinear motion based on the limiting effect of the positioning shaft 16 and the longitudinal axial tracking push rod 3. Is a daylighting device tracking centering circle, the center of the centering circle is the axis of the hinge shaft, and the moving point is the axis O5 of the hinge shaft 20. When sunlight is at different azimuth positions, the track points of the moving points on the centering circle also have an included angle lambda which is in one-to-one tracking correspondence with the moving points. The angle lambda can vary from 0 deg. to 90 deg.. The size of the included angle lambda depends on the linear displacement H of the longitudinal axial tracking walking block 4, when the longitudinal angle of sunlight is the smallest, the longitudinal axial tracking walking block 4 is farthest from the axis of the rotating branch cylinder 2, and when the longitudinal angle of sunlight is the largest, the longitudinal axial tracking walking block 4 is closest to the axis of the rotating branch cylinder 2.
The second clutch transmission structure comprises a transverse axial tracking conical gear 11, the lower part of the transverse axial tracking conical gear 11 is connected with a transverse axial tracking walking gear 12, and the upper part of the transverse axial tracking conical gear 11 is connected with the driving motor 6 through a second clutch 13. The transverse tracking running gear 12 meshes with a fixed gear 7. The transverse axis tracks the rotation of the walking gear 12, and changes the direction of the moment while outputting the moment. Since the fixed gear 7 does not rotate, the transverse axial tracking traveling gear 12 is forced to roll circumferentially around the fixed gear 7. And drives all components rigidly connected with the rotary support cylinder 2 to synchronously rotate. The azimuth tracking swing arm 5 can drive the whole lighting array through the hinge shaft 20 and the linkage driving rod group to synchronously track sunlight in the transverse axial direction.
The linkage driving rod group comprises a transverse axial linkage push rod 14 and a longitudinal axial linkage push rod 15, the azimuth tracking swing arms 5 of the adjacent single lighting devices are connected through the transverse axial linkage push rod 14, and the longitudinal axial tracking walking blocks 4 of the adjacent single lighting devices are connected through the longitudinal axial linkage push rod 15. The lighting array is formed by arranging a plurality of single lighting devices in an east-west row, a south-north row and an order on a horizontal plane. The azimuth tracking swing arm 5 of each individual daylighting device in the array has a hinge shaft 20, and a transverse axial linkage push rod 14 is hinged with the hinge shaft 20. The hinge axes simultaneously move in a curved line as the horizontal axis moves horizontally toward the associated push rod 14. Similarly, the single lighting devices in the same row synchronously rotate and move simultaneously. The longitudinal and axial linkage push rod 15 is connected with the driving motor 6 through the longitudinal and axial tracking push rod 3 and the longitudinal and axial tracking walking block 4. When the driving motor 6 drives the longitudinal axial tracking push rod 3 to do plane movement, the plurality of longitudinal axial linkage push rods 15 also synchronously follow the plane movement, and the lighting devices of the whole array can be driven by one power to synchronously and synchronously track sunlight in a linkage manner.
The horizontal axial linkage push rod 14 drives a plurality of azimuth tracking swing arms 5 in the same row to rotate synchronously under the action of external driving force. The longitudinal and axial tracking walking block 4 is driven by the sliding shaft 18 to synchronously rotate in a linkage manner, namely, the external driving force drives the east-west transverse axial tracking mechanism and simultaneously drives the north-south longitudinal axial tracking mechanism to synchronously rotate. During tracking, external driving force applied to the east-west linkage push rod drives the hinge shaft 20 to do circular motion around a circle center O1; the swing motion locus is a circle having a center at O1 and a pivot point at the hinge axis 20, and a radius at a length of a straight line segment from the center at O1 to the hinge axis 20, and is a maximum arm length of the swing arm 5 tracked in azimuth. N is the common normal line of the incident surface of the single lighting device, and when the common normal line N is parallel to the sunlight, the condenser has the maximum luminous flux. When the external force drives the hinge shaft 20 to rotate counterclockwise or clockwise about the center O1 through a round angle θ, the incident surface simultaneously traces through the equal round angle θ. Corresponding to the rounded angle θ, the cumulative amount of sunlight received by the daylighting device is equivalent to the area of the shadow in the circle. When θ is rotated through 90 °, the shaded area is a half circle area. Similarly, when the moving point A4 is rotated through a 90 ° radius, the daylighting tracker tracks through a total of 180 ° radii. The equivalent accumulated sunlight accumulation amount of the lighting device is a circle area. Therefore, the lighting device can track the sunlight synchronously and in the same direction, and has the maximum light receiving amount.

More specifically, the azimuth tracking swing arm 5 is an L-shaped metal body, one end of which is rigidly connected to the rotation support 2 and the other end of which is connected to the transverse axial linkage push rod 14 through a hinge shaft 20; the middle part of the azimuth tracking swing arm 5 is provided with a section of sliding groove 17, and the sliding groove 17 is a linear motion rail track of the longitudinal axial tracking walking block 4. The hinge shaft 20 is in a planar position, offset from the slide slot 17, by a distance in order to avoid the swinging of the azimuth tracking swing arm 5 to the true west or the true east, colliding with the rotation fulcrum 2. The longitudinal axis tracking walking block 4 extends obliquely to one side to form a second oblique connecting part 21, the second oblique connecting part 21 is hinged with the longitudinal axis linkage push rod 15 through a hinge shaft 20, the first oblique connecting part 19 and the second oblique connecting part 21 are positioned on the same side, and the transverse axis linkage push rod 14 is parallel to the longitudinal axis linkage push rod 15.
Wherein, the upper part of the rotary support 2 is provided with an upper main rotary hinged support 22, and the upper main rotary hinged support 22 is hinged with the daylighting device hinged support 1 through a hinged shaft. The azimuth tracking swing arm 5 is rigidly connected with the rotary support cylinder 2, the rotary support cylinder 2 is rotatably connected with the fixed shaft through an upper bearing and a lower bearing, and the rotary support cylinder 2 is rigidly connected with the upper main rotary hinged support 22 and the daylighting device hinged support 1. Except that the base and the fixed shaft of the rotary support 2 are stationary members, the other members are rotatable or swingable with respect to the fixed shaft. The purpose is that when the external force pushes the azimuth tracking swing arm 5 to do circular motion, the rotary support cylinder 2 drives the related parts to rotate in the same direction.
