[0031] 1. A support assembly is provided. By pulling out the latch pin, the latch pin is disengaged from the slot, and then the turntable is rotated. The turntable drives the rotating rod and the adjusting gear to rotate, and the adjusting gear drives the main gear to rotate. Since the diameter of the adjusting gear is smaller than that of the main gear, the main gear rotates slower and the adjustment is more precise. The rotation of the main gear drives the rack and the slide bar on one side to rise, and the rack and the slide bar on the other side to fall. The slide bar drives the step block to slide inside the step groove, so that the step block on one side lifts the upper plate and the step block on the other side falls, which is convenient for adjusting the angle of the upper plate.

It solves the problem that the device is only convenient for adjusting the angle of a single photovoltaic panel. However, in a photovoltaic system, it is generally composed of a large number of photovoltaic panels, and the device is not convenient for adjusting a large number of photovoltaic panels at one time, which is more troublesome when adjusting the angles of a large number of photovoltaic panels.

[0032] 2. A positioning component is provided. When installing the photovoltaic panel, the photovoltaic panel is placed inside the placement frame. The weight of the photovoltaic panel drives the placement frame to be pressed down, and the placement frame drives the guide rod to slide down and compresses spring four. The placement frame will squeeze the inclined surface of the trapezoidal block at the same time, so that the trapezoidal block moves to the outside of the placement frame, and the trapezoidal block drives the sliding block to slide in the side groove. The sliding block compresses spring three, and the trapezoidal block drives the lower rod to slide into the lower part of the U-shaped cylinder at the same time. The interior of the U-shaped cylinder is filled with hydraulic oil, and the lower rod squeezes the hydraulic oil, so that the upper rod approaches the placement frame, and the upper rod drives the installation rod and the clamping plate to move, so that the clamping plates on both sides fix the photovoltaic panel, and then slide the bolt, the bolt slides inside the installation groove, moves the bolt to the sliding block, tightens the bolt to position the sliding block, which is convenient for the stable installation of the photovoltaic panel and improves the stability during angle adjustment.

[0062] Working principle: When using the device, first, Figure 1-Figure 11 As shown, by pulling out the latch pin 512, the latch pin 512 is disengaged from the slot 513, and then the turntable 511 is rotated, the turntable 511 drives the rotating rod 53 and the adjusting gear 54 to rotate, and the adjusting gear 54 drives the main gear 52 to rotate. Since the diameter of the adjusting gear 54 is smaller than the main gear 52, the main gear 52 rotates slower and the adjustment is more precise. The rotation of the main gear 52 drives the rack 58 and the slide bar 56 on one side to rise, and the rack 58 and the slide bar 56 on the other side to descend, and the slide bar 56 drives the step block 57 to slide inside the step groove 59, so that the step block 57 on one side lifts the upper plate 3 and the step block 57 on the other side descends, so that it is easy to adjust the angle of the upper plate 3.

[0063] The rising and falling distances of the sliding rods 56 on both sides are the same, which is convenient for better supporting the upper plate 3. After adjustment, the pin 512 is inserted into the slot 513 at the corresponding position again to position it. By connecting the rotating rod 53 of another device with one end of the rotating rod 53 of the initial device, sliding the sleeve 514, the block 516 is located at the position of the slot 520. At this time, the elastic force of the spring 2 517 drives the block 516 to be stuck in the slot 520, which is convenient for fixing the two rotating rods 53. At this time, rotating the turntable 511 of the initial device can drive the devices in the same row to adjust their angles.

[0064] When installing the photovoltaic panel, the photovoltaic panel is placed inside the placement frame 4. The weight of the photovoltaic panel drives the placement frame 4 to be pressed down. The placement frame 4 drives the guide rod 7 to slide down and compress the spring four 8. The placement frame 4 will squeeze the inclined surface of the trapezoidal block 66 at the same time, so that the trapezoidal block 66 moves to the outside of the placement frame 4. The trapezoidal block 66 drives the sliding block 62 to slide in the side groove 61. The sliding block 62 compresses the spring three 63. The trapezoidal block 66 simultaneously drives the lower rod 69 to slide into the lower part of the U-shaped cylinder 68. The interior of the U-shaped cylinder 68 is filled with hydraulic oil. The lower rod 69 squeezes the hydraulic oil, so that the upper rod 610 approaches the placement frame 4. The upper rod 610 drives the installation rod 611 and the clamping plate 612 to move, so that the clamping plates 612 on both sides fix the photovoltaic panel. Then the sliding bolt 65 slides inside the installation groove 64, moves the bolt 65 to the sliding block 62, tightens the bolt 65 to position the sliding block 62, and facilitates the stable installation of the photovoltaic panel.
