[0011] Preferably, the method for using the multi-angle adjustable flexible photovoltaic bracket comprises the following steps:

[0012] S1: When the tilt angle of the photovoltaic panel needs to be adjusted, the driving motor is controlled to work, thereby driving the rotating shaft to rotate, and then driving the driving disk and the missing angle bevel gear to rotate synchronously, thereby driving the two extrusion arc plates to respectively contact the bottom of an L-shaped frame, so that the two L-shaped frames slide upward along a mounting frame respectively, thereby driving the control crank to deflect in the rotating groove, and then the movable column moves in the direction of the movable groove, so that the reset spring contracts synchronously, so that the clamping block moves in the direction away from the clamping groove, and then meshes with one of the matching bevel gears under the continuous rotation of the missing angle bevel gear, thereby driving the matching bevel gear to rotate, thereby driving the driving shaft to rotate, and then driving the placement frame and the control frame to deflect synchronously, so as to adjust the tilt direction of the photovoltaic panel, and after the extrusion arc plate is out of contact with the L-shaped frame, the control crank is reset under the action of the reset spring, so that the clamping block is re-clamped in any one of the clamping grooves, thereby fixing the control shaft, and then completing the locking of the driving shaft, so that the position of the photovoltaic panel is synchronously locked;

[0013] S2: When the driving motor is controlled to work, the missing angle bevel gear has not yet meshed with the matching bevel gear. At this time, under the rotation of the driving disk, one of the fan-shaped pressing pieces is driven to press against the bottom of one end of the triangular plate, so that the triangular plate, under the cooperation of the trigger crank and the connecting rod, makes the auxiliary block slide in the sliding track, and the compression spring is tightened and released once, so that the triangular plate tilts to the other side, and then the matching block slides in the moving groove, so that it slides from one end of the moving groove to the other end, and in the process of sliding, it drives the matching tooth groove rod to move synchronously, so that the trigger gear meshing with it rotates, and then under the action of the spring telescopic rod, drives the cleaning frame to move from one end of the cleaning track to the other end;

[0014] S3: Each time the triangle plate is triggered to deflect, the cleaning frame drives the first gear to move on the driving toothed rod, causing the first gear to rotate, thereby driving the linked toothed rod and the linked frame meshing therewith to slide synchronously in the auxiliary track, causing the second gear to move synchronously, and then, under the action of the auxiliary toothed rod, the second gear rotates synchronously during the movement, thereby driving the fixed toothed rod and the moving frame meshing therewith to slide synchronously on the control track, allowing them to move from one end of the control track to the other end, thereby driving the action frame and the cleaning roller to move from one side of the placement frame to the other side, so that the photovoltaic panels on the placement frame can be cleaned.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present invention, when the device is used, when it is necessary to adjust the working angle of the photovoltaic panel, the staff controls the driving component to work, and controls the locking component to work during the work process, thereby unlocking the photovoltaic panel, thereby facilitating the control of the tilt angle of the photovoltaic panel on the support frame, and automatically locking the position of the photovoltaic panel after the adjustment is completed, and before adjusting the tilt angle, the setting trigger component works to drive the matching component to work, so that the cleaning component automatically cleans the surface of the photovoltaic panel.

At the same time, after the photovoltaic panel is used for a long time, the surface of the photovoltaic panel can be automatically cleaned, thereby avoiding the possibility of insufficient power generation effect due to dust on the surface of the photovoltaic panel, thereby achieving the automatic locking of the photovoltaic panel after deflection and the automatic cleaning of the surface of the photovoltaic panel, so as to avoid the effect of low convenience and insufficient power generation effect.

[0017] In the present invention, when the inclination angle of the photovoltaic panel needs to be adjusted, the driving motor is controlled to work, thereby driving the rotating shaft to rotate, and then driving the driving disk and the missing angle bevel gear to rotate synchronously, thereby driving the two extrusion arc plates to respectively contact the bottom of an L-shaped frame, so that the two L-shaped frames slide upward along a mounting frame respectively, thereby driving the control crank to deflect in the rotating groove, and then the movable column moves in the direction of the movable groove, so that the reset spring is synchronously contracted, so that the clamping block moves in the direction away from the clamping groove, and then meshes with one of the matching bevel gears under the continuous rotation of the missing angle bevel gear, thereby driving the matching bevel gear to rotate, thereby driving the driving shaft to rotate, and then driving the placement frame and the control frame to deflect synchronously, so as to adjust the inclination direction of the photovoltaic panel, and after the extrusion arc plate is out of contact with the L-shaped frame, the control crank is reset under the action of the reset spring, so that the clamping block is re-clamped in any one of the clamping grooves, thereby fixing the control shaft, and then the drive shaft is locked, so that the position of the photovoltaic panel is synchronously locked, thereby avoiding the need for staff to lock the adjusted photovoltaic panel through a locking mechanism, reducing the working steps, and improving the convenience of the use process.

[0018] When the cam is in motion, the gear shifts from one end of the gear to the other, and the spring forces the gear shifters to move in a synchronous manner, thereby facilitating the cleaning of the gears.

[0019] In the present invention, each time the triangular plate is triggered to deflect, under the action of the cleaning frame, the first gear is driven to move on the driving toothed rod, so that the first gear rotates, and then drives the linked toothed rod and the linked frame meshing therewith to slide synchronously in the auxiliary track, so that the second gear moves synchronously, and then under the action of the auxiliary toothed rod, the second gear rotates synchronously during the movement, and then drives the fixed toothed rod and the moving frame meshing therewith to slide synchronously on the control track, so that they can move from one end of the control track to the other end, and then drives the action frame and the cleaning roller to move from one side of the placement frame to the other side, so that it cleans the photovoltaic panel on the placement frame, so that it can automatically clean the surface of the photovoltaic panel, thereby avoiding the possibility of insufficient power generation effect due to dust on the surface of the photovoltaic panel.

[0046] S2: When the driving motor 39 is controlled to work, the missing angle bevel gear 38 has not yet meshed with the matching bevel gear 35. At this time, under the rotation of the driving disk 31, one of the fan-shaped pressing pieces 820 is driven to press against the bottom of one end of the triangular plate 812, so that the triangular plate 812, under the cooperation of the trigger crank 813 and the connecting rod 814, makes the auxiliary block 815 slide in the sliding track 816, and makes the compression spring 817 tighten and release once, so that the triangular plate 812 tilts to the other side, thereby making the matching block 818 slide in the moving groove 819, so that it slides from one end in the moving groove 819 to the other end, and in the process of sliding, drives the matching tooth groove rod 831 to move synchronously, so that the trigger gear 832 meshing with it rotates, and then drives the cleaning frame 834 to move from one end of the cleaning track 835 to the other end under the action of the spring telescopic rod 833;

[0047] S3: Each time the triangular plate 812 is triggered to deflect, under the action of the cleaning frame 834, the first gear 92 is driven to move on the driving toothed rod 91, so that the first gear 92 rotates, and then drives the linked toothed rod 96 and the linked frame 95 meshing therewith to slide synchronously in the auxiliary track 94, so that the second gear 97 moves synchronously, and then under the action of the auxiliary toothed rod 93, the second gear 97 rotates synchronously during the movement, and then drives the fixed toothed rod 100 and the moving frame 99 meshing therewith to slide synchronously on the control track 98, so that it can move from one end of the control track 98 to the other end, and then drives the action frame 101 and the cleaning roller 102 to move from one side of the placement frame 37 to the other side, so that it can clean the photovoltaic panel 5 on the placement frame 37.
