Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panels, in particular to a rotary drive mechanism. Background Art

[0002] Photovoltaic panels (solar panels) are devices that absorb sunlight and convert solar radiation energy directly or indirectly into electrical energy through the photoelectric effect or photochemical effect. Photovoltaic panels use a special semiconductor structure and are characterized by high efficiency, low cost, environmental protection and reliability. They are cheaper than coal-fired power, do no harm to endangered species, and have a lower greenhouse effect.

[0003] Photovoltaic panels are generally mounted on a rotatable drive mechanism, which can drive the photovoltaic panels to rotate, thereby changing the angle of the photovoltaic panels and improving the light conversion rate. However, the current photovoltaic panel drive mechanism is directly connected to the shaft on which the photovoltaic panels are installed. When the photovoltaic panels are blown by the wind outdoors, they will swing slightly. The swinging force will be transmitted to the motor of the drive mechanism through the shaft, which can easily cause damage to the motor. Secondly, the photovoltaic panels are installed at a certain height, and the drive mechanism is located on the top of the mounting bracket. When the drive mechanism fails in the later stage, it is not convenient for inspection and maintenance. Therefore, the utility model proposes a rotating drive mechanism. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 4 As shown, it involves a rotation drive mechanism, including a left side plate 1 and a right side plate 2, the bottom ends of the left side plate 1 and the right side plate 2 are commonly fixedly connected with a cross bar 3, the top ends of the left side plate 1 and the right side plate 2 are commonly rotatably connected with a cross axis 5, a plurality of mounting frames 6 for mounting photovoltaic panels are fixed on the surface of the cross axis 5, a protective cover 13 is fixedly connected to the side of the right side plate 2 away from the cross axis 5, a driving component for driving the cross axis 5 to rotate is provided at the bottom end of the inside of the protective cover 13, a lifting component for driving the driving component to move is installed on the inner bottom wall of the protective cover 13, and a locking component is installed at the top of the right side plate 2 and inside the protective cover 13.

[0024] like Figure 1-Figure 2 As shown, the bottom ends of the left side plate 1 and the right side plate 2 are fixedly connected to a base 4, and a plurality of mounting holes are opened on the side of the base 4.

[0025] The base 4 can be fixed on the ground through the mounting holes to achieve the installation and fixation of the mechanism.

[0026] like Figure 1-Figure 2As shown, one end of the transverse axis 5 located in the protective cover 13 is fixedly connected to the driven wheel 9, and the driving assembly includes a motor 7. The driving end of the motor 7 is fixedly connected to the driving wheel 8, and the surfaces of the driving wheel 8 and the driven wheel 9 are jointly sleeved with a belt 10.

[0027] Under the transmission of the belt 10 , the motor 7 can drive the driven wheel 9 to rotate through the driving wheel 8 , thereby driving the horizontal axis 5 to rotate, thereby adjusting the angle of the photovoltaic panel installed on the surface of the horizontal axis 5 .

[0028] like Figure 1-Figure 4 As shown, the lifting assembly includes a square tube 14 fixed to the inner bottom wall of the protective cover 13, a sliding rod 15 is slidably connected inside the square tube 14, the top of the sliding rod 15 is fixedly connected to the motor 7, the inner bottom wall of the square tube 14 is rotatably connected to a screw rod 16 through a bearing, the top of the screw rod 16 passes through the sliding rod 15 and is threadedly rotatably connected to the sliding rod 15, the bottom end of the screw rod 16 is fixedly connected to a first bevel gear 17, the side wall of the bottom end of the square tube 14 is rotatably connected to an adjusting shaft 18 through a bearing, one end of the adjusting shaft 18 located in the square tube 14 is fixedly connected to a second bevel gear 19, the second bevel gear 19 is meshed with the first bevel gear 17, and the other end of the adjusting shaft 18 is fixedly connected to a hand wheel 20.

[0029] By rotating the second bevel gear 19 through the hand wheel 20, the first bevel gear 17 can be driven to rotate, thereby driving the screw rod 16 to rotate. The screw rod 16 will drive the slide bar 15 to move up or down along the square tube 14, thereby changing the height of the motor 7. When the motor 7 descends, the belt 10 is tightened, and when the motor 7 rises, the belt 10 becomes loose, which is convenient for replacing the belt 10.

[0030] like Figure 4 As shown, a strip opening 21 is formed on the side of the square tube 14 away from the hand wheel 20 , and a slider 22 is fixedly connected to the bottom end of the slide rod 15 . The slider 22 is located inside the strip opening 21 and is slidably connected to the strip opening 21 .

[0033] After the angle of the horizontal axis 5 is adjusted, the electric telescopic rod 11 can be used to drive the arc-shaped card plate 12 to move upward. After the arc-shaped card plate 12 is clamped on the surface of the horizontal axis 5, the horizontal axis 5 can be fixed to prevent the swinging force of the photovoltaic panel from being transmitted to the horizontal axis 5 and driving the horizontal axis 5 to rotate. The rubber pad can increase the friction between the arc-shaped card plate 12 and the horizontal axis 5, and increase the fixing firmness.

[0034] like Figure 1 As shown, the protective cover 13 is fixedly connected with an inspection cover 23 by bolts away from the side of the right side plate 2. It is convenient to inspect and maintain the components in the protective cover 13 by disassembling the inspection cover 23.

[0035] Working principle: The photovoltaic panel can be installed and fixed on the mounting frame 6. After the motor 7 drives the horizontal axis 5 to rotate through the belt 10, the angle of the photovoltaic panel can be adjusted. Before each angle adjustment, the electric telescopic rod 11 drives the arc-shaped card plate 12 to drop away from the horizontal axis 5. After the angle adjustment is completed, the electric telescopic rod 11 drives the arc-shaped card plate 12 to re-cage on the surface of the horizontal axis 5 to fix the horizontal axis 5. When the drive assembly needs to be inspected, the inspection cover 23 can be removed, and the drive assembly can be inspected or maintained at the bottom of the right side plate 2, reducing the difficulty of inspection.
