[0038] like Figure 1-Figure 7 A wind-resistant photovoltaic component installation fixture and photovoltaic roof structure shown include multiple groups of columns 2 arranged on the top of the roof 1, and the lengths of these columns 2 are increased in sequence to form a slope. Such a design is conducive to the natural discharge of rainwater and can also maximize the use of sunlight. A first rotating seat 8 is fixedly installed on the top of each column 2, and a rotating rod 4 is rotatably arranged in the first rotating seat 8. In order to support the photovoltaic panel 7, two first baffles 5 are fixedly installed on multiple rotating rods 4 on the same side, and the two first baffles 5 are arranged in parallel to each other for placing and supporting the photovoltaic panel 7. In order to further enhance the stability of the photovoltaic panel 7, a second baffle 6 is provided between the two photovoltaic panels 7 and on the outside of the side photovoltaic panel 7. The two sides of the second baffle 6 are respectively in contact with the corresponding photovoltaic panels 7, thereby forming a stable support structure.

[0039] The top of the second baffle 6 is provided with an insertion hole 19, and the top of the rotating rod 4 is provided with a threaded hole 20. A bolt 18 is provided through the insertion hole 19, and the bottom end of the bolt 18 is threadedly connected with the threaded hole 20. In this way, the photovoltaic panel 7 can be fixed on the rotating rod 4 through the cooperation of the bolt 18 and the threaded hole 20.

[0040] In order to enhance the wind resistance of the entire structure, a hollow rod 13 is provided through one side of multiple columns 2 in the same row. Multiple third rotating seats 12 are provided on the outer wall of the hollow rod 13 and the top of the roof 1. Second rotating seats 10 are fixedly provided at the bottom of both ends of the rotating rod 4, and dampers 11 are rotatably provided between the second rotating seats 10 and the corresponding third rotating seats 12. The lengths of the multiple dampers 11 increase in sequence, but the damping force is the same. They provide swing damping for the rotating rod 4, thereby enhancing the stability of the entire structure.

[0041] In order to fix the plurality of third rotating seats 12, the column 2 and the hollow rod 13 together to form a whole, a fixing assembly is provided. The fixing assembly includes a first rectangular opening 29 opened on the outer wall of the hollow rod 13, and the inner walls of the third rotating seat 12 and the column 2 are fixedly provided with a pin 32 adapted to the first rectangular opening 29. An insertion rod 30 is inserted into the hollow rod 13, and a second rectangular opening 33 corresponding to the first rectangular opening 29 is opened on the outer wall of the insertion rod 30, and one end of the pin 32 is located in the second rectangular opening 33. The outer wall of the insertion rod 30 is also provided with a plurality of equidistant annular grooves 31 for limiting the pin 32. A limiting mechanism for limiting the insertion rod 30 is provided at one end of the hollow rod 13 to ensure that the insertion rod 30 will not fall off the hollow rod 13. When the pin 32 moves from the second rectangular opening 33 to the annular groove 31, the insertion rod 30 and the pin 32 will not move relative to each other.

[0042] In order to connect the plurality of columns 2 into a whole, a connection assembly is provided. The connection assembly includes a plurality of connection seats 14 provided on the top of the roof 1, and a bending portion 15 is provided at both ends of the connection seat 14, and the bending portion 15 is fixedly connected to the parapet on the roof 1 through a bolt 18. A plurality of connection strips 16 are fixedly provided on the top of the plurality of connection seats 14, and a stud 17 corresponding to the column 2 is fixedly provided on the top of the connection strip 16. Each stud 17 is connected to the column 2 through a nut, and a cement pier 3 is poured on the outside thereof to further enhance the stability of the connection and prevent damage to the top of the roof 1.

[0043] In order to limit the position of the insertion rod 30, the specific implementation of the limiting mechanism is as follows: an inner screw ring 40 is sleeved on the outer wall of the hollow rod 13, and the inner screw ring 40 can rotate freely on the hollow rod 13. In order to position the inner screw ring 40, a positioning ring 37 is fixedly sleeved on the outer wall of the hollow rod 13. An outer screw ring 36 is slidably sleeved on the outer wall of the insertion rod 30, and the outer screw ring 36 can be used in conjunction with the inner screw ring 40. The two are tightly connected by rotation, and the movement of the insertion rod 30 can be limited. In order to limit the rotation of the outer screw ring 36, a plurality of sliding grooves 34 are provided on the outer wall of the insertion rod 30, and a slider 35 is slidably provided in the sliding groove 34, and the plurality of sliders 35 are fixedly provided on the inner wall of the outer screw ring 36. Prevent the outer screw ring 36 from rotating relative to the insertion rod 30. In addition, a plurality of positioning strips 38 are fixedly provided on the outer wall of the hollow rod 13, and a positioning groove 39 corresponding to the positioning strips 38 is provided on the inner wall of the outer screw ring 36. When the outer screw ring 36 is rotated to a proper position, the positioning bar 38 will be inserted into the positioning groove 39 , thereby further limiting the outer screw ring 36 .

[0044] In order to clamp the photovoltaic panel 7, a resisting portion 27 is provided on both sides of the second baffle 6, and a rubber strip 28 is provided at the top of the resisting portion 27. The rubber strip 28 resists the photovoltaic panel 7 to protect the photovoltaic panel 7 and increase the friction force to prevent the photovoltaic panel 7 from sliding. A rectangular hole 24 corresponding to the insertion hole 19 is provided on one side of the second baffle 6, and a trapezoidal block 25 is slidably provided in the rectangular hole 24. The trapezoidal block 25 can be used in conjunction with the two resisting portions 27. When the bolt 18 passes through the insertion hole 19 and is screwed into the threaded hole 20 of the rotating rod 4, the retaining ring 26 fixedly sleeved on the outer wall of the bolt 18 will push the trapezoidal block 25 to move downward, and the inclined surface of the trapezoidal block 25 will contact the inclined surface of the resisting portion 27 and push the resisting portion 27 to expand outward, so that the rubber strip 28 is in close contact with the photovoltaic panel 7, thereby fixing the photovoltaic panel 7.

[0045] In order to support the middle part of the photovoltaic panel 7, a plurality of grid bars 21 are detachably connected between two adjacent rotating rods 4, and the grid bars 21 are used to support the photovoltaic panel 7 and increase the stability of the photovoltaic panel 7. Wedge blocks 22 are set at both ends of the grid bar 21, and slots 23 corresponding to the wedge blocks 22 are opened at the top of the rotating rod 4. When the grid bar 21 needs to be installed on the rotating rod 4, it is only necessary to align the wedge blocks 22 at both ends of the grid bar 21 with the slots 23 and insert them. Since the shape of the wedge blocks 22 matches the shape of the slots 23, the grid bar 21 will be very stable after installation and will not fall off easily. The bottom of the second stop bar 6 conflicts with the two groups of wedge blocks 22 at the top of the rotating rod 4, and is used to fix the two groups of wedge blocks 22 at the same time. In this way, when the second stop bar 6 is fixed to the rotating rod 4 by bolts 18, it will also fix the wedge blocks 22 of the grid bar 21 in the slots 23, thereby achieving the fixation of the grid bar 21.

[0046] In order to connect the multiple first rotating seats 8 into one body, a connecting shaft 9 is rotatably provided on one side of the multiple first rotating seats 8 on the same side, and the rotating rod 4 is rotatably sleeved on the connecting shaft 9. In this way, the multiple first rotating seats 8 can be connected together through the connecting shaft 9 to form an integral structure, thereby increasing the stability of the entire installation fixture. A gap is left between two rotating rods 4 in the same row to prevent the rotating rods 4 from conflicting with each other when swinging, thereby affecting the swinging effect. The size of the gap can be adjusted according to actual conditions to ensure that the rotating rod 4 can swing smoothly.

[0047] During installation, the connection seat 14 is placed on the roof 1, and then the two ends of the connection seat 14 are bent according to the position of the column 2 to form a bent portion 15, and then the bent portion 15 is fixed to one side of the parapet by an expansion bolt 18, and then a plurality of connection strips 16 are fixed to a plurality of connection seats 14 by welding, and studs 17 are welded to the top of the connection strips 16, and then the columns 2 are inserted into the plurality of studs 17 in turn and fixed by nuts. After the fixing is completed, the cement pier 3 is used for fixing and protection;

[0048] Then, the rotating rod 4 is placed in the first rotating seat 8, and the connecting shaft 9 is inserted into the multiple first rotating seats 8 to connect the multiple rotating rods 4 in the same row. Then, the hollow rod 13 is inserted into the multiple columns 2 on the same side. During the plugging process, the third rotating seat 12 is sequentially sleeved on the outer wall of the hollow rod 13 until one end of the hollow rod 13 passes through the column 2 on the left from the right side. During the plugging process, the pin 32 is located in the first rectangular opening 29, and then the insertion rod 30 is inserted into the hollow rod 13, and the second rectangular opening 33 is made to correspond to the pin 32. After pushing the third rotating seat 12 to adjust the position of the third rotating seat 12, after the adjustment is completed, the insertion rod 30 is rotated to make the pin 3 2 moves from the second rectangular opening 33 to the annular groove 31, so that the pillar 2, the third rotating seat 12 and the insertion rod 30 can be limited by the pin 32 and the annular groove 31 respectively, and then the outer screw ring 36 is sleeved on the insertion rod 30, so that the slider 35 slides in the slide groove 34, and the outer screw ring 36 is pushed to approach the positioning ring 37 until the positioning bar 38 is inserted into the positioning groove 39. At this time, the outer screw ring 36 will not rotate, and the insertion rod 30 is limited by the slider 35 and the slide groove 34. Finally, the inner screw ring 40 is pushed and rotated, so that the inner screw ring 40 is threaded on the outer screw ring 36, until the inner wall of one side of the inner screw ring 40 conflicts with the positioning ring 37, so that the outer screw ring 36 can be limited to the left and right;

[0049] After the installation is completed, the grid bar 21 is clamped between two adjacent rotating rods 4, the wedge block 22 is clamped in the slot 23, and then the first baffles 5 are welded on one side of the plurality of rotating rods 4 in the same row. After the first baffles 5 are installed, one side of the photovoltaic panel 7 is inserted between the two first baffles 5, and the bottom of the photovoltaic panel 7 is in contact with the grid bar 21, and then the second baffle 6 is inserted between the two adjacent photovoltaic panels 7 and the side of the photovoltaic panel 7, and the second baffle 6 is pushed to move at the same time, so that the bolt 18 corresponds to the threaded hole 20, and the bolt 18 is pressed downward, and the bolt 18 moves downward to drive the retaining ring 26 When the retaining ring 26 moves downward, the retaining ring 26 can drive the trapezoidal block 25 to move downward. During the downward movement of the trapezoidal block 25, the abutment portion 27 can be deformed, and the rubber strip 28 can be abutted against one side of the photovoltaic panel 7. When the bolt 18 contacts the rotating rod 4, the bolt 18 is rotated again to screw the bolt 18 into the corresponding threaded hole 20. At the same time, the plurality of grid bars 21 below can be abutted and fixed by the second retaining strip 6 to prevent the grid bars 21 from rubbing against the photovoltaic panel 7. Finally, the damper 11 is installed between the corresponding second rotating seat 10 and the third rotating seat 12, and all installation is completed.

[0050] When encountering strong winds, since the photovoltaic panel 7 is tilted, the wind will blow the bottom end of the photovoltaic panel 7 to rotate upward, stretching the damper 11 at the bottom during the rotation, and the damper 11 at the high end will retract, allowing the photovoltaic panel 7 to rotate and preventing the wind from overturning the photovoltaic panel 7.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the present invention.
