Since the photovoltaic support ceiling is inclined, in order to ensure safety, a circular hole can be provided only at the rear end of the strip hole 20. When the photovoltaic panel 18 moves downward as a whole, the photovoltaic panel 18 can be prevented from falling directly from the photovoltaic support ceiling. The diameter of the circular hole 21 is greater than the width of the strip hole 20. A concave seat 24 is provided at the lower side of the grooved tube 10, and a pair of connecting bolts 22 are passed through the concave seat 24. The upper ends of the connecting bolts 22 are passed through the strip holes 20, and the upper ends of the connecting bolts 22 are provided with end caps, and the lower ends of the end caps act on the grooved tube 10. A nut 23 is provided at the lower end of the connecting bolt 22, and the upper ends of the nut 23 act on the concave seat 24. A pair of cross bars 25 are provided on both sides of the concave seat 24, and a side plate 26 is sleeved on the cross bars 25 on the same side. A lower plate 37 is provided at the upper end of the side plate 26, and a moving strip hole 370 is opened on the lower plate 37, and a pull rod 33 is passed through the moving strip hole 370. The length direction of the movable bar hole 370 is parallel to the length direction of the lower plate 37. A spacer block 38 is provided at the upper end of the pull rod 33. A wing plate 39 is provided at the upper end of the spacer block 38. The spacer block 38 is located between two adjacent photovoltaic panels 18. The lower wall of the wing plate 39 acts on the upper wall of the photovoltaic panel 18. A lower nut 330 is provided at the lower end of the pull rod 33. The lower wall of the concave seat 24 contacts with an upper screw rod 34. A lower pull-down horizontal plate 32 is threadedly connected to the upper screw rod 34. The pull rod 33 is rotatably arranged at both ends of the lower pull-down horizontal plate 32. The lower pull-down horizontal plate 32 is located at the upper end of the lower nut 330.

[0023] Specifically, a sleeve 36 is provided on the lower wall of the concave seat 24 , and the upper end of the lifting screw 34 is inserted into the sleeve 36 .

[0024] Specifically, the outer wall of the side panel 26 is provided with a vertical plate 27, and the inner wall of the side panel 26 is provided with a plurality of anti-slip teeth, which are vertically arranged.

An internal pressure rod 30 is movably provided in the vertical groove 29 and the inclined groove 28, and a pair of pull plates 31 are provided at both ends of the internal pressure rod 30. The pull plates 31 are located on both sides of the vertical plate 27, and the lower ends of the pull plates 31 are installed on the pull-down horizontal plate 32.

[0025] When operating this embodiment, the photovoltaic bracket roof is installed first, specifically, the photovoltaic pile foundation is poured first, and then the bracket is installed on the photovoltaic pile foundation, and then the rectangular tube 1 is installed on the bracket by bolts, and then the groove tube 10 is installed on the rectangular tube 1 by bolts according to the predetermined spacing, so that the basic framework of the photovoltaic bracket roof is built, and then the photovoltaic panels 18 are placed on two adjacent groove tubes 10 one by one. When placing, it is necessary to ensure that there is a predetermined interval between the photovoltaic panels 18, and whenever a pair of photovoltaic panels 18 is placed, at least one inner plate 12 needs to be inserted into the groove tube 10, and the concave member 14 is installed and fixed by the first screw 13. After the fixing is completed, the lower wall of the positioning plate 15 acts on the upper side of the photovoltaic panel 18, which is used for the complete positioning of the photovoltaic panel 18 in the X direction. At this time, the photovoltaic panel 18 has been fixed, so it will not move. This operation is carried out until all the photovoltaic panels 18 are fixed.

[0026] Then the construction workers place the concave seat 24 with the connecting bolt 22 on the lower side of the trough pipe 10. When placing it, the construction workers insert the end cap of the connecting bolt 22 into the round hole 21, and make the connecting bolt 22 pass through the strip hole 20, and tighten the concave seat 24 against the lower wall of the trough pipe 10 by screwing the nut 23. When fixing, it is necessary to ensure that the spacer 38 can be inserted into the gap between two adjacent photovoltaic panels 18. When the concave seat 24 is fixed, the position of the spacer 38 and other components on the trough pipe 10 will be locked. After that, the pull rod 33 can be rotated so that the wing plate 39 is located directly above the photovoltaic panel 18.

[0027] Then, the construction personnel rotate the lower end cap 35 by a wrench, and the rotation of the lower end cap 35 will drive the upper screw 34 to rotate, and the rotation of the upper screw 34 will increase the distance between the pull-down horizontal plate 32 and the concave seat 24, and along with the downward movement of the pull-down horizontal plate 32, the inner pressure rod 30 will be pulled downward by the pull plate 31, and as the inner pressure rod 30 moves downward, it will act on the inclined groove 28, so that the side plate 26 is closely attached to the outer wall of the grooved tube 10, and in this process, the wing plate 39 is in a state of approaching the photovoltaic panel 18, and when the inner pressure rod 30 moves from the inclined groove 28 to the vertical groove 29, the pull-down horizontal plate 32 will further act on the upper end of the lower nut 330, and finally the lower wall of the wing plate 39 will act on the upper wall of the photovoltaic panel 18, and the fixing operation of the photovoltaic panel 18 will be completed. If necessary, the fixing effect of the wing plate 39 on the photovoltaic panel 18 can be improved by screwing down the nut 330.
