An adjustable bracket for supporting photovoltaic panels

Abstract

The present invention discloses an adjustable bracket for supporting a photovoltaic panel, belonging to the technical field of photovoltaic panel structures. By setting the adjustable bracket, the photovoltaic panels distributed over the entire area are integrated into several photovoltaic panel adjustment units arranged in strips. Each adjustment unit consists of a driving vehicle and several arranged photovoltaic panel frames. When the driving vehicle reciprocates along the extension track, the dialing block will push aside the blocking part of the blocking column and roller, causing the roller to move downward. Through several reciprocating movements of the driving vehicle, the sliding roller falls to the bottom end of the vertical groove track, enabling the photovoltaic panel to change its angle with the movement of the sun, thereby improving the energy conversion efficiency of the photovoltaic panel. For this adjustment bracket, only one electric device, that is, one driving vehicle, needs to be configured for each row of brackets. Compared with setting electric mechanical adjustment devices on each photovoltaic panel, the number of electric devices in the entire photovoltaic panel area is greatly reduced, the maintenance difficulty of the overall photovoltaic panel is reduced, the economic cost of the photovoltaic panel and its own energy consumption rate are reduced.

DETAILED DESCRIPTION

[0023] like Figures 1 to 6 As shown, the present invention discloses an adjustable bracket for supporting photovoltaic panels, such as Figure 1 As shown, it includes two vertical groove rails 1, two horizontal groove rails 2 and a bottom mesh plate 3 for installing photovoltaic panels. The vertical groove rails 1 and the horizontal groove rails 2 are integrated on a frame to form a supporting structure. The two vertical groove rails 1 are parallel to each other and placed vertically; the two horizontal groove rails 2 have the same height, and the horizontal groove rails 2 are located at the side of the middle section of the vertical groove rails 1. Figure 1 , cylindrical sliding rollers 31 are respectively provided at the two ends of the front and rear edges of the bottom mesh plate 3, and a clamping piece can be fixedly connected to the bottom mesh plate 3 for fixing the photovoltaic panel, and the sliding rollers 31 of the front edge of the bottom mesh plate 3 are respectively slidably arranged in the transverse groove rail 2, and the two ends of the rear edge of the bottom mesh plate 3 are respectively slidably arranged in the vertical groove rail 1, and the length of the sliding roller 31 located in the transverse groove rail 2 is less than the width of the transverse groove rail 2, and the length of the sliding roller 31 located in the vertical groove rail 1 is longer than the length of the vertical groove rail 1, so that the sliding roller 31 extends from the outer side of the vertical groove roller; in a free state, the rear edge of the bottom mesh plate 3 moves up and down along the vertical groove rail 1, and the front edge of the bottom mesh plate 3 moves horizontally along the transverse groove rail 2, so that the bottom mesh plate 3 changes its angle on this frame, and the rotation angle of the bottom mesh plate 3 can cover the movement trajectory of the sun throughout the day; also refer to Figure 1 , and also includes an extension track 4, the extension track 4 is perpendicular to the front and rear edges of the bottom mesh plate 3, the extension track 4 is located on one side of the frame formed by the vertical groove rail 1 and the horizontal groove rail 2, the length of the extension track 4 is equal to the horizontal distance between the vertical groove rail 1 and the horizontal groove rail 2, and the extension track 4 is provided with a connecting structure at the head and tail, so that a plurality of the extension tracks 4 can be connected head to tail, such as Figure 3 As shown, when the photovoltaic panels are distributed and installed, each extension track 4 of the vertically arranged photovoltaic panel units is connected end to end, and a driving vehicle 5 is provided on each of the connected extension tracks 4, such as Figure 2 A shift block 6 is vertically slidably provided on the driving vehicle 5, and a plurality of blocking portions 7 for blocking the sliding roller 31 are arranged on the vertical groove rail 1 close to the extension rail 4. The driving vehicle 5 reciprocates on the connected extension rail 4, so that the shift block 6 shifts away the blocking portion 7 blocking the sliding roller 31 until the sliding roller 31 falls to the bottom end of the vertical groove rail 1.

[0024] In this scheme, by setting an adjustable bracket, the photovoltaic panels distributed over the entire area are integrated into a number of photovoltaic panel adjustment units arranged in strips. Each adjustment unit consists of a driving vehicle 5 and a number of photovoltaic panel frames arranged in strips. When the driving vehicle 5 moves back and forth along the extension track 4, the shifting block 6 on the driving vehicle 5 moves downward a distance along the stroke of the single extension track 4. This distance is the distance between adjacent blocking portions 7. During each unidirectional movement of the driving vehicle 5, the shifting block 6 will shift the blocking portion 7 of the blocking column and blocking roller, so that the blocking roller moves downward. After several reciprocating movements, the sliding roller 31 falls to the bottom end of the vertical groove rail 1, so that the angle of the photovoltaic panel on the bottom mesh plate 3 changes. By adjusting the speed of the driving vehicle 5, the photovoltaic panel can change its angle as the sun moves, thereby improving the energy conversion efficiency of the photovoltaic panel. This adjustment bracket only needs to be equipped with one electric device, i.e., one driving vehicle 5, for each row of brackets. Compared with setting an electric mechanical adjustment device on each photovoltaic panel, it greatly reduces the number of electric devices in the entire photovoltaic panel area, reduces the difficulty of maintenance of the overall photovoltaic panel, and reduces the economic cost of the photovoltaic panel and its own energy consumption rate.

[0025] In a further solution, Figure 2 , Figure 4 and Figure 5 As shown, the blocking portion 7 includes a blocking pin 71, a spring 72, a turning block 73, a traction wire 74, a slider 75 and a resisting shaft 76; the blocking pin 71 extends from one side of the inner groove of the vertical groove rail 1 and is blocked on the bottom side of the sliding roller 31, the spring 72 resists the inner end of the blocking pin 71, the blocking pin 71 compresses the spring 72 and can be retracted into the vertical groove rail 1, the turning block 73 is located at the end of the spring 72 away from the blocking pin 71, the traction wire 74 is a steel wire, one end of the traction wire 74 is connected to the inner end of the blocking pin 71, extends toward the spring 72 and bypasses the turning block 73 to make a 90° turn, the end of the traction wire 74 is fixed to the slider 75, the slider 75 is slidably arranged inside the vertical groove rail 1, the resisting shaft 76 resists the slider 75, and the outer end of the resisting shaft 76 is provided with an arc block 8, the shift block 6 reciprocates and resists the arc block 8, so that the arc block 8 pulls the blocking pin 71 to be recovered.

[0026] In this scheme, the arc block 8 can be compressed by the reciprocating movement of the shift block 6, so that the arc block 8 moves toward the inner side of the vertical groove rail 1. When the arc block 8 moves, it drives the anti-shaft 76 to move, and the anti-shaft 76 drives the slider 75 to move. The slider 75 pulls back the traction wire 74, and the traction wire 74 bypasses the turning block 73 and pulls back the stop pin 71, so that the stop pin 71 is recovered from the groove of the vertical groove rail 1, so that the sliding roller 31 loses the support of the stop pin 71 and then falls to the next stop pin 71 position; in this structure, by setting the arc block 8, the shift block 6 can push away the stop pin 71 during the back and forth movement along the extension track 4, thereby improving the mechanical control efficiency of the drive vehicle 5 and further reducing energy consumption.

[0027] In a further solution, as Figure 4 and Figure 5 shown, the lower edge of the outer end of the stop pin 71 is chamfered. A cross shaft 61 for lifting the sliding roller 31 is fixedly provided on the shifting block 6. As the shifting block 6 moves upward, the sliding roller 31 abuts against and moves the stop pin 71 away, and moves to the top end of the vertical groove track 1. Through the upward movement of the cross shaft 61 in this solution, the photovoltaic panel can be reset again to continue absorbing the energy of the photovoltaic panel the next day. This structure fully automates the photovoltaic panel. At night, the driving vehicle 5 gradually resets each photovoltaic panel, and adjusts the angle of the photovoltaic panel during the day. The reset of the photovoltaic panel can be completed without adding additional structures, saving the investment in materials and equipment, and enhancing the overall economic value.

[0028] In a further solution, as Figure 1 and Figure 2 shown, a plurality of blocking portions 7 are also provided on the vertical groove track 1 far from the extension track 4. Between the two abutting shafts 76 in the blocking portions 7 at the same height, a synchronizing rod 9 is fixedly connected. This structure provides blocking portions 7 on both vertical groove tracks 1, and the blocking portions 7 at the same height are synchronized through the synchronizing rod 9. Under the control of the driving vehicle 5, when the shifting block 6 compresses the arc-shaped block 8, the two blocking portions 7 at the same height can be released simultaneously. This structure can improve the falling stability of the photovoltaic panel and enhance the overall support of the photovoltaic panel. Compared with the support of a single-sided vertical groove track 1, the support of the double-sided vertical groove track 1 can ensure the stable rotation of the photovoltaic panel and prevent skew and jamming.

[0029] In a further solution, as Figure 6 shown, the driving vehicle 5 includes a vehicle body 51. A guiding buckle 52 and wheels 53 are provided at the bottom of the vehicle body 51. The extension track 4 is arranged as a long strip structure. The guiding buckle 52 is clamped on the extension track 4, and the wheels 53 rotate to drive the driving vehicle 5 to move, so that the guiding buckle 52 moves along the extension track 4.

[0030] In this structure, the vehicle body 51 is driven to move by the wheels 53, and the guiding buckle 52 provides a guiding function, so that when the driving vehicle 5 moves along the extension track 4, it has a certain degree of slipperiness, avoiding the overall jamming of the driving vehicle 5 when the driving vehicle 5 and the frame are jammed.

[0031] In a further solution, as Figure 5 shown, a guiding column 54 is provided on the driving vehicle 5. The shifting block 6 is slidably arranged on the guiding column 54. A motor 62 is provided on the shifting block 6, and a gear 63 is provided on the motor 62. The gear 63 meshes with one side of the guiding column 54; a plurality of hemispherical grooves 541 are arranged in a row on the guiding column 54, and an elastic ball pin 64 is provided on the shifting block 6. The heights of the hemispherical grooves 541 are arranged in the same way as the heights of the blocking portions 7.

[0032] In this structure, guided by the guide posts 54, the shifting block 6 moves along the guide posts 54 through the gear-rack structure of the gear 63. During each stage movement of the shifting block 6, through the positioning of the hemispherical groove 541 and the elastic ball pin 64, the elastic ball pin 64 snaps into the hemispherical groove 541, and the height of the shifting block 6 is flush with the blocking portion 7, ensuring that the height of the shifting block 6 is fixed when prying open the blocking pin 71, and avoiding the failure of prying open caused by the deviation of the stopping position of the shifting block 6.

[0033] In a further solution, as Figure 6 shown, a number of fixed-point holes 41 are provided on the extension track 4. An electric cylinder 55 is provided in the driving vehicle 5, and an elastic column 56 is provided at the end of the electric cylinder 55. When the elastic column 56 snaps into the fixed-point hole 41, the horizontal shaft 61 is located at the bottom end of the vertical rail groove, and the roller 31 on the vertical rail groove is located on the surface of the horizontal shaft 61. When the photovoltaic panel is recovered at night, the electric cylinder 55 extends. When the driving vehicle 5 moves to the side of the frame, the elastic column 56 snaps into the fixed-point hole 41 to fix the position of the driving vehicle 5. At this time, the horizontal shaft 61 is located at the bottom end of the vertical rail groove, and the roller 31 is located on the surface of the horizontal shaft 61. The motor 62 does work, the horizontal shaft 61 moves upward, driving the roller 31 to push open the blocking pin 71, and finally returning to the top of the vertical groove rail 1. During the day and during the movement of the driving vehicle 5, the electric cylinder 55 retracts, and the elastic column 56 will not snap into the fixed-point hole 41, and the driving vehicle 5 moves smoothly. This structure ensures the fixed-point return of the photovoltaic panel by the driving vehicle 5 and avoids the failure of the driving vehicle 5 to reach the fixed point.

[0034] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and not to limit them.
