First, the movable plate 17 is moved to the inner wall side of the rotating frame 12, and then the fixed frame 19 is placed in the rotating frame 12 and connected to the upper end of the connecting bar 13, and the rotating frame 12 is pushed to one side so that the second limiting block 20 is inserted into the second limiting groove 47. At the same time, the threaded column 16 is rotated to drive the movable plate 17 to move, so that the first limiting block 18 is inserted into the first limiting groove 21, thereby fixing the fixed frame 19 in the rotating frame 12, which facilitates the disassembly and assembly of the rotating frame 12.

[0037] A plurality of I-beams 22 are evenly fixedly installed in the fixed frame 19 in the horizontal direction, and a plurality of connecting plates 23 are evenly fixedly installed in the vertical direction. The connecting plate 23 is fixed to the lower end of the I-beam 22, which increases the firmness of the fixed frame 19. During construction, the three ends of the fixed frame 19 are welded first, and then the I-beam 22 and the connecting plate 23 are welded. The end of the fixed frame 19 that contacts the I-beam 22 is welded last.

[0038] The upper end of each I-beam 22 is slidably connected to a support plate 28 through a slider 26. The four ends of the support plate 28 are fixedly installed with an extension plate 29. One end of the extension plate 29 is fixedly installed with a mounting plate 30. The mounting plate 30 is L-shaped, and one end is welded to the outer side of the extension plate 29. The mounting plate 30 is connected to the photovoltaic module 24 through a connector 25. The lower end of the photovoltaic module 24 contacts the upper end of the extension plate 29 and the support plate 28 to support them. The front and rear ends of the left and right sides of the lower end of the support plate 28 are fixedly installed. There is a support rod 27, which is L-shaped. One end of the support rod 27 is fixedly installed on the lower end of the support plate 28, and the other end is fixedly installed with a slider 26. The slider 26 is slidably inserted into the inner sides of the left and right ends of the I-beam 22. The upper and lower outer walls of the slider 26 are slidably connected to the upper and lower inner walls of the I-beam 22. When the slider 26 slides in the I-beam 22, the support plate 28 will not shake at the upper end of the I-beam 22. At the same time, a protrusion is provided at the bottom end of the support plate 28, and the lower end of the protrusion is slidably connected to the top of the I-beam 22.

[0039] Four splicing plates 31 are fixedly connected to the outer side walls of the support plate 28. The splicing plates 31 and the extension plates 29 are arranged in an alternating manner. The upper ends of the splicing plates 31 are flush with the upper ends of the extension plates 29 and the support plates 28, so as to support the photovoltaic module 24. The outer ends of the four splicing plates 31 are flush with the outer sides of the four ends of the photovoltaic module 24. Two symmetrically arranged splicing plates 31 have a splicing groove 1 32 on the lower side of the outer end of one, and a splicing groove 2 33 on the upper side of the other outer end. The other two symmetrical splicing plates 31 have a slide groove 34 on one outer end, and a slide bar 35 is fixedly installed on the other outer end. When the photovoltaic module 24 is spliced ​​horizontally, the splicing groove 1 32 and the splicing groove 2 33 are connected to each other. When the photovoltaic module 24 is spliced ​​vertically, the slide bar 35 is slidably inserted into the slide groove 34, thereby completing the horizontal and vertical splicing of the photovoltaic module 24, and the installation is simple and quick.

[0040] A limiting component is installed on one side of the slider 26, and the limiting component is located on the inner side of the I-beam 22. The limiting component includes a fixed cylinder 37, and a fixed block 36 is fixedly installed on the outer wall of one end of the fixed cylinder 37. One end of the fixed block 36 is fixedly installed on the outer wall of one end of the slider 26. When the slider 26 is inserted into the I-beam 22, the limiting component will be inserted into the I-beam 22 synchronously. The lower end of the fixed cylinder 37 is slidably connected to a moving cylinder 38, and the upper end of the fixed cylinder 37 is slidably connected to a moving column 39. The moving column 39 is convex. One end is slidably inserted into the moving cylinder 38, and a spring 41 is fixedly installed at one end of the moving column 39. The end of the spring 41 away from the moving column 39 is fixedly connected to the inner wall of the bottom end of the moving cylinder 38. The other ends of the moving column 39 and the moving cylinder 38 are fixedly installed with an expansion plate 42, and the outer ends of the expansion plate 42 are fixedly installed with an anti-skid plate 43. When the spring 41 is in a compressed state, the anti-skid plates 43 at the upper and lower ends of the fixed cylinder 37 contact the inner walls of the upper and lower ends of the inner side of the I-beam 22, thereby preventing the slider 26 from moving in the I-beam 22.

[0041] Plug holes 40 are provided on the side walls of the fixed cylinder 37, the movable cylinder 38 and the movable column 39. The plug holes 40 on the side walls of the fixed cylinder 37, the movable cylinder 38 and the movable column 39 are connected by compressing the spring 41 again, and then the plug pin 44 is inserted into the plug hole 40 to fix the movable cylinder 38 and the movable column 39 to the inner end of the fixed cylinder 37. At this time, the spring 41 is in a compressed state, and the outer end of the anti-slip plate 43 is separated from the inner wall of the I-beam 22, and a pull ring 45 is fixedly installed on the outer end of the plug pin 44, and a connecting rope 46 is fixedly installed on the outer wall of the pull ring 45. After moving the photovoltaic module 24 to a suitable position, hold the photovoltaic module 24 with one hand and pull the connecting rope 46 with the other hand to pull the plug pin 44 out of the plug hole 40. Under the reaction force of the spring 41, the movable cylinder 38 and the movable column 39 pop out to the outside, so that the anti-slip plate 43 contacts the inner wall of the I-beam 22 to fix the photovoltaic module 24.

[0042] A photovoltaic system comprises the above-mentioned photovoltaic fixing bracket with adjustable inclination angle.

[0043] In actual use, during construction, the three ends of the fixed frame 19 are welded first, and then the I-beam 22 and the connecting plate 23 are welded. The end of the fixed frame 19 that contacts the I-beam 22 is not welded first, and the photovoltaic module 24 is fixed to the upper end of the support plate 28 through the connecting piece 25. The plug hole 40 on the side wall of the fixed cylinder 37, the movable cylinder 38 and the movable column 39 is connected by compressing the spring 41, and then the plug pin 44 is inserted into the plug hole 40, and the connecting rope 46 is tied to the pull ring 45 at the rear end of the plug pin 44. Then the slider 26 is inserted into the I-beam 22, and the limiting component is inserted into the I-beam 22 at the same time. After the photovoltaic module 24 is moved to the appropriate position, hold the photovoltaic module 24 with one hand and pull the connecting rope 46 with the other hand to pull the plug pin 44 out of the plug hole 40. Under the reaction force of the spring 41, the movable cylinder 38 and the movable column 39 pop out to the outside, so that The anti-skid plate 43 contacts the inner wall of the I-beam 22 to fix the photovoltaic module 24, and then the photovoltaic module 24 is quickly spliced ​​on the I-beam 22 in sequence, and then the other end of the fixed frame 19 is welded. The inner walls of the four ends of the fixed frame 19 are in contact with the outer wall of the photovoltaic module 24. Then the fixed frame 19 is placed in the rotating frame 12 and connected to the upper end of the connecting strip 13, and the rotating frame 12 is pushed to one side, so that the limit block 20 is inserted into the limit groove 2 47, and at the same time, the threaded column 16 is rotated to drive the movable plate 17 to move, so that the limit block 18 is inserted into the limit groove 1 21, so that the fixed frame 19 is fixed in the rotating frame 12, and the motor 4 drives the threaded rod 5 to rotate, and drives the threaded sleeve 7 to move with the guide sleeve 8. When the guide sleeve 8 moves, it moves with one end of the driving rod 10, and the driving rod 10 lifts the rotating frame 12 upward or moves it downward, thereby adjusting the angle of the rotating frame 12.
