[0002] With the large-scale development of photovoltaic power generation projects, the demand for photovoltaic racks is also increasing. Currently, most photovoltaic racks use a truss structure, with a single row of trusses as the supporting unit for photovoltaic modules. Such photovoltaic racks are fixed after installation, making it inconvenient to adjust the angle and height. When folding, they need to be disassembled one by one and cannot be folded quickly.

[0003] Chinese utility model publication number CN206259888U discloses a photovoltaic bracket and a photovoltaic bracket group, including a bracket column, an angle adjustment strut, a bracket diagonal beam, a first transmission rod and a fixing piece. One end of the bracket column is hinged to the bracket diagonal beam, and one end of the bracket diagonal beam is hinged to one end of the angle adjustment bracket. A serrated groove is provided on the angle adjustment bracket, and a first gear is provided on the first transmission rod. The first gear cooperates with the serrated groove. The first transmission rod is rotatably connected to the bracket column to adjust the distance from the first gear to the connecting part. The angle adjustment bracket can be connected to the bracket column through a fixing piece.

[0004] The photovoltaic bracket in the above patent can adjust the angle, but when it needs to be raised in height or folded for storage, it cannot automatically adjust the height and fold quickly, and can only be assembled through traditional disassembly, which is more troublesome. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] Example 1: Figures 1 to 3The foldable photovoltaic support shown is easy to adjust, including a photovoltaic support frame 1, a support frame 2 and a base 3 arranged in sequence from top to bottom. The photovoltaic panel 11 is installed on the photovoltaic support frame 1 by means of gasket bolts. The photovoltaic support frame 1 facilitates the installation of the photovoltaic panel 11. The photovoltaic support frame 1 is laid on the support frame 2. The middle part is movably connected to the top rod of the support frame 2 by a hinge, and the two side surfaces extend to the front and back sides of the support frame 2. The top rod of the photovoltaic support frame 1 is arranged symmetrically with the center, and the two sides are gathered or spread out toward the inner side. The bottom of the base 3 is welded with a support leg 31, which is fixed to the ground by bolts. The support leg 31 plays a supporting and fixing role. The bottom plate of the support frame 2 is a lifting plate 21, which is connected to the base 3 by a lifting mechanism. The lifting mechanism is fixed to the base 3 and drives the lifting plate 21 to move up and down, thereby driving the entire support frame 2 to move up and down, and adjusting the height of the photovoltaic support frame 1. The middle of the support frame 2 is connected to the two inner side surfaces of the photovoltaic support frame 1 through a set of adjustment mechanisms to adjust the opening angle of the photovoltaic support frame 1. The two sets of adjustment mechanisms are respectively located on both sides of the support frame 2.

[0026] Since the photovoltaic support frame 1 is laid on the support frame 2 and movably connected thereto, and both sides extend to the front and rear sides of the support frame 2, the expansion angle of the photovoltaic support frame 1 can be adjusted by an adjustment mechanism, and when the photovoltaic support frame 1 is completely gathered inward, it can be quickly folded and stored, making storage more convenient; by setting a lifting mechanism to connect with the support frame 2 on which the photovoltaic support frame 1 is installed, the height of the photovoltaic support frame 1 can be changed in time very conveniently through the lifting mechanism, which facilitates the adjustment of its height; similarly, by setting an adjustment mechanism to cooperate with the photovoltaic support frame 1, it is easier to adjust the expansion height of the photovoltaic support frame 1, and the photovoltaic panel 11 carried by the photovoltaic support frame 1 can adjust its own height and angle in various scenarios to collect light energy most effectively.

[0027] Example 2: Based on Example 1, a lifting mechanism is preferably designed. The lifting mechanism includes a screw 41 and a guide rod 42. The screw 41 and the guide rod 42 vertically pass through the lifting plate 21. The bottom end of the guide rod 42 is fixed to the base 3. The screw 41 rotates to drive the lifting plate 21 to move up and down. Specifically, the guide rod 42 and the screw 41 are respectively located on the left and right sides of the lifting plate 21, standing opposite each other, so that the lifting plate 21 can maintain force balance. The screw 41 is circumferentially threaded with the lifting plate 21. A bearing with a seat is installed on the base 3. A motor 32 fixed to the bottom of the base 3 is provided directly below the bearing with a seat. The bottom end of the screw 41 passes through the bearing with a seat and is fixedly connected with the output shaft of the motor 32. The motor 32 is a stepper motor. The stepper motor 32 has multiple gears, which can raise the lifting plate 21 to different arrangements and flexibly adjust the height of the photovoltaic support rack 1. The bottom end of the guide rod 42 is fixed on the base 3, and the circumference is clearance-matched with the lifting plate 21 to avoid restricting the up and down movement of the lifting plate 21. The top ends of the guide rod 42 and the screw 41 are respectively connected to the limit blocks 43 as a whole. The limit blocks 43 can limit the lifting plate 21 to prevent the lifting plate 21 from moving upward an excessive distance and separating from the guide rod 42 and the screw 41. The output shaft of the motor 32 drives the screw 41 to rotate, and the rotation of the screw 41 drives the lifting plate 21 to rotate. However, since the guide rod 42 passes through the lifting plate 21 and its bottom end is fixed to the base 3, the position of one end of the lifting plate 21 is limited by the guide rod 42 and cannot rotate with the screw 41. Therefore, it can only move up and down along the screw 41 under the limiting action of the guide rod 42. Therefore, under the cooperation of the screw 41 and the guide rod 42, the lifting plate 21 can slide up and down, thereby driving the support frame 2 to move up and down, completing the adjustment of the height of the photovoltaic support frame 1, which has the advantage of being able to more conveniently and flexibly adjust the height of the photovoltaic bracket; the output shaft of the motor 32 drives the screw 41 to rotate, and also provides power for the up and down movement of the lifting plate 21, thereby realizing the height adjustment of the photovoltaic bracket.

[0028] Example 3: Based on Example 1, the adjustment mechanism is preferably designed, and the adjustment mechanism includes a pushing device 51, one end of which can move up and down along the support rod 22 arranged vertically in the middle of the support frame 2, and the other end of the pushing device 51 controls the opening angle of the photovoltaic support frame 1 through the flip frame 52.

[0029] Specifically, the upper and lower ends of the strut 22 are respectively fixedly connected to the top rod of the support frame 2 and the middle part of the lifting plate 21. A horizontally arranged cross brace 23 is also fixed in the middle of the support frame 2. The two ends of the cross brace 23 are respectively fixedly connected to the middle part of the two side plates of the support frame 2, and the middle part is fixedly connected to the strut 22 to form a cross shape. The arrangement of the cross brace 23 and the strut 22 can enhance the connection stability of the support frame 2. The pushing device 51 is arranged below the cross brace 23. The pushing device 51 uses a pushing cylinder, and the extension length of the push rod of the pushing cylinder can be manually controlled. A sliding frame 24 is provided on the rod body of the support rod 22 below the cross brace 23. The pushing cylinders of the two sets of adjustment mechanisms are connected together through the sliding frame 24. The support rod 22 passes through the sliding frame 24, and the sliding frame 24 can move up and down along the support rod 22. The two ends of the sliding frame 24 are respectively hinged to the two pushing cylinders through a rotating shaft, that is, the fixed plates of the two pushing cylinders arranged on the bottom extend into the two sides of the sliding frame 24 respectively, and then are connected together through the rotating shaft, and the rotating shaft is locked by a nut, so that the push rod of the pushing cylinder can rotate around the rotating shaft when it is extended and retracted, thereby driving the sliding frame 24 to slide up and down on the rod body of the support rod 22, and controlling the opening angle of the photovoltaic support frame 1 by rotating the flip frame 52.

[0030] The flip frame 52 is a rectangular frame structure, including two side rods and a cross bar connecting the two side rods, wherein the two side rods are vertically connected to the cross brace 23, that is, a connecting seat 25 is fixed on the cross brace 23, and one end of the two side rods is hinged to the connecting seat 25 through a rotating shaft, so that the flip frame 52 can rotate up and down around the cross brace 23. The cross bar is located opposite to the cross brace 23 and is parallel to the cross brace 23. The push rod of the push cylinder is hinged to the flip frame 52 through the rotating shaft, that is, the push rod of the push cylinder is hinged to the inner side of the cross brace 23 through the rotating shaft. The push rod is controlled when it is extended and retracted. The flip frame 52 is controlled to rotate, and one end of the two side rods of the flip frame 52 away from the cross brace 23 is movably connected to the photovoltaic support frame 1 through the adjustment frame 53, that is, the one end of the two side rods of the flip frame 52 away from the cross brace 23 is hinged to the bottom of the two side rods of the adjustment frame 53 through the rotating shaft, and a connecting frame 12 is fixed in the middle of the photovoltaic support frame 1, and the tops of the two side rods of the adjustment frame 53 are hinged to the connecting frame 12 through the rotating shaft. This connection method enables the flip frame 52 to control the opening angle of the photovoltaic support frame 1 through the adjustment frame 53.

[0031] Since the push rod of the pushing cylinder is hinged to the flip frame 52, and one end of the flip frame 52 is hinged to the cross brace 23, and the other end is movably connected to the photovoltaic support frame 1 through the adjustment frame 53, and the base 3 of the pushing cylinder is hinged to the support rod 22 and can move up and down along the support rod 22, when the push rod of the pushing cylinder is extended or retracted, the push rod can drive the adjustment frame 53 to flip around the cross brace 23 and drive the adjustment frame 53 to rotate, thereby controlling the photovoltaic support frame 1 to expand or contract, thereby achieving the effect of automatically adjusting the expansion angle of the photovoltaic support frame 1, and when the push rod is fully retracted, the photovoltaic support frame 1 is completely gathered inward, realizing rapid folding of the photovoltaic bracket.

[0032] During use, the stepper motor 32 controls the rotation of the screw 41, and the lifting plate 21 moves up and down along the screw 41 under the restriction of the guide rod 42, thereby driving the support frame 2 to move and completing the height adjustment of the photovoltaic bracket; when the cylinder push rod is pushed to extend and retract, it can drive the flip frame 52 to rotate and change the expansion angle of the photovoltaic support frame 1 through the adjustment frame 53. Therefore, manually adjusting the extension distance of the cylinder push rod can flexibly adjust the rotation angle of the photovoltaic support frame 1, and when the push rod is fully retracted, the photovoltaic support frame 1 is folded and stored.

[0033] The above embodiments merely represent specific implementation methods of the present application. Although the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of protection of the present application. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the technical concept of the present application, and these modifications and improvements are all within the scope of protection of the present application.
