Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic installation, in particular to a photovoltaic support structure suitable for curved roofs. Background Art

[0002] As solar photovoltaic power generation technology becomes more and more mature, the installation scenarios of photovoltaic power generation are no longer limited to flat land and water surfaces. Any large open area may be used to install photovoltaic power stations.

[0003] In building roofs, taking curved roofs as an example, especially colored steel tile roofs, since the roof has a certain curvature, when installing solar panels, the installation surfaces of the two guide rails underneath are usually not on the same section, making it impossible for the pressing blocks to effectively contact the solar panels, and the guide rails cannot provide effective support for the solar panels, resulting in the solar panels being not firmly installed on the curved roof, posing a safety hazard. Utility Model Content

[0004] The purpose of the utility model is to provide a photovoltaic support structure suitable for curved roofs, solve the problems existing in the prior art, and be able to adapt to any curved roof, so that when adjacent guide rails are used to support solar panels, their installation surfaces are guaranteed to be coplanar, and the pressing blocks are effectively fitted with the solar panels to achieve firm installation.

[0005] In order to achieve the above purpose, the solution of the utility model is:

[0006] A photovoltaic support structure suitable for a curved roof, comprising a plurality of guide rails installed on the roof and parallel to each other, and a plurality of pressure block assemblies installed on the guide rails; both side surfaces of the guide rails are provided with inward grooves; the pressure block assembly comprises a limit block, a slider, a pressure block and a screw; the limit block is slidably fitted on the upper surface of the guide rail; both sides of the limit block are provided with barbs hooked in the groove, and the upper end of the limit block is provided with a first curved surface, and the first curved surface is provided with a long strip hole along its own curved direction; the upper end of the slider is provided with a second curved surface matching the first curved surface, and the middle of the second curved surface is provided with a threaded hole; the screw is successively inserted into the long strip holes of the pressure block and the limit block and then locked into the threaded hole of the slider.

[0007] A third arc surface is provided on the upper surface of the guide rail, and the third arc surface is concentric with the first arc surface. The upper and lower end surfaces of the slider are respectively gap-matched with the first arc surface and the third arc surface.

[0008] Preferably, two flanges extend downward from both sides of the lower end surface of the sliding block, and the flanges abut downward against the third arc surface of the guide rail.

[0009] Preferably, the lower end surface of the flange is a fourth curved surface matching the third curved surface.

[0010] The photovoltaic support structure suitable for curved roofs also includes an L-shaped support; a plurality of L-shaped supports are arranged on the roof, and the L-shaped supports are fixedly connected to the guide rails by bolts.

[0011] Preferably, a side surface of the guide rail is provided with a slot for placing the bolt.

[0012] Preferably, the side surface of the guide rail provided with the slot and the opposite surface of the L-shaped support are both provided with anti-slip grooves.

[0013] After adopting the above technical solution, the utility model has the following technical effects:

[0014] During installation, the utility model only needs to place the solar panel on two adjacent guide rails so that the two guide rails support the lower surface of the solar panel and form an inclined surface with a certain slope. Since the limit block is provided with a first arc surface and an elongated hole, the pressing block is adjusted to be parallel to the above-mentioned inclined surface by swinging the slider in the limit block, so that the pressing block can perfectly fit the upper surface of the solar panel frame, thereby firmly mounting the solar panel on the guide rail and achieving fixation. The limit block is mainly relatively fixed to the guide rail by the cooperation of the barb and the groove, so that the position of the limit block on the guide rail can be adjusted arbitrarily to meet the layout requirements of different photovoltaic arrays.

[0030] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0031] refer to Figures 1 to 9 As shown, the utility model discloses a photovoltaic support structure suitable for a curved roof, comprising a plurality of guide rails 1 installed on a roof 10 (especially a curved roof) and parallel to each other, and a plurality of pressing block assemblies 2 installed on the guide rails 1;

[0032] Both sides of the guide rail 1 are provided with inward grooves 11;

[0033] The pressing block assembly 2 includes a limit block 21, a slider 22, a pressing block 23 and a screw 24;

[0034] The limit block 21 is slidably fitted on the upper surface of the guide rail 1; barbs 211 hooked in the groove 11 are provided on both sides of the limit block 21 to prevent the limit block 21 from falling off the guide rail 1, and a first arc surface 212 is provided at the upper end of the limit block 21, and a long strip hole 213 is provided on the first arc surface 212 along its own arc direction;

[0035] The upper end of the slider 22 is provided with a second arc surface 221 matching the first arc surface 212, and a threaded hole 222 is provided in the middle of the second arc surface 221;

[0036] The pressing block 23 is provided with a through hole (located in the middle of the pressing block 23, not shown in the figure);

[0037] The screw 24 is inserted into the through hole of the pressing block 23 and the long hole 213 of the limiting block 21 in sequence and then locked into the threaded hole 222 of the slider 22 . The pressing block 23 can rotate according to the movement path of the slider 22 in the limiting block 21 .

[0038] Through the above scheme, when installing the utility model, it is only necessary to place the solar panel 20 on two adjacent guide rails 1, so that the two guide rails 1 support the lower surface of the solar panel 20 and form an inclined surface with a certain slope. Since the limit block 21 is provided with a first arc surface 212 and a long hole 213, the pressing block 23 is adjusted to be parallel to the above-mentioned inclined surface by the swing of the slider 22 in the limit block 21, so that the pressing block 23 can perfectly fit the upper surface of the frame of the solar panel 20, so that the solar panel 20 is firmly installed on the guide rail 1 and fixed; the limit block 21 is mainly relatively fixed to the guide rail 1 by the cooperation of the barb 211 and the groove 11, so that the position of the limit block 21 on the guide rail 1 can be adjusted arbitrarily to meet the layout requirements of different photovoltaic arrays.

[0039] Specific embodiments of the present utility model are shown below.

[0040] The upper surface of the guide rail 1 is provided with a third curved surface 12, which is concentric with the first curved surface 212 / the second curved surface 221, so that the space formed between the third curved surface 12 and the first curved surface 212 is fan-shaped, and the upper and lower end surfaces of the slider 22 are respectively gap-matched with the first curved surface 212 and the third curved surface 12. The space formed between the third curved surface 12 and the first curved surface 212 constrains the slider 22, and the slider 22 can only swing along the direction of the curved surface and cannot rotate in other directions. At the same time, the swing range of the slider 22 will be limited by the stroke of the long strip hole 213 of the limit block 21. During installation, the solar panel 20 is placed on the third curved surface 12 of two adjacent guide rails 1 to form a section. The pressing block 23 is rotated at a certain angle according to the curvature of the roof 10 to keep the contact surface of the pressing block 23 on the adjacent guide rail 1 and the solar panel 20 in the same plane and parallel to the above-mentioned section, thereby ensuring that each pressing block 23 can perfectly fit the frame of the solar panel 20, so as to cope with roofs 10 with different curvatures, so that the solar panel 20 can be effectively installed on the curved roof.

[0041] Furthermore, two flanges 223 extend downward from both sides of the lower end surface of the slider 22, and the flanges 223 abut downward against the third arc surface 12 of the guide rail 1, so that the contact area between the slider 22 and the guide rail 1 is reduced, which is conducive to the rapid movement of the slider 22 in the space between the third arc surface 12 and the first arc surface 212.

[0042] Secondly, the lower end surface of the flange 223 is a fourth arc surface 224 matching the third arc surface 12 , so that the flange 223 fits the third arc surface 12 .

[0043] The utility model further comprises an L-shaped support 3 ; a plurality of L-shaped supports 3 are arranged on the roof 10 , and the L-shaped support 3 is fixedly connected to the guide rail 1 by bolts 4 , so that the guide rail 1 is installed and fixed on the roof 10 .

[0044] Furthermore, a slot 13 for placing the bolt 4 is provided on the side of the guide rail 1 .

[0045] Secondly, the side surface of the guide rail 1 provided with the slot 13 and the opposite surface of the L-shaped support 3 are both provided with anti-skid patterns 14, 31 (or called concave and convex teeth) to achieve the purpose of mutual cooperation and anti-skid.

[0046] See also Figure 8 and Fig. 9 According to the different positions of the pressing block assembly 2 in the photovoltaic matrix, the pressing block 23 of the pressing block assembly 2 generally has two implementation modes, namely, a side pressing block 23a with a single-side pressing plate, and a middle pressing block 23b with double-side pressing plates.

[0047] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
