[0002] With the integration and development of the photovoltaic industry and the power system, substation rooftops, as idle spaces, are gradually becoming an important site for the installation of photovoltaic systems.

[0003] The waterproof and anti-corrosion layers on the substation roof serve as a protective barrier for the core equipment inside, and any penetration or irreversible damage is prohibited. However, existing photovoltaic systems are generally installed on the roof through penetrating anchoring or welding, which can easily damage the original building structure and cause roof leaks. Moreover, due to the different construction environments of substations, photovoltaic panels need to be installed at specific angles to achieve efficient power generation. The existing fixed photovoltaic support foundations cannot adjust the angle, which limits their applicability in diverse substation scenarios. Utility Model Content

The rubber buffer pad is tightly attached to the purlin by tightening the pressing bolts.

[0009] As a further embodiment of this utility model: the adjustment structure includes multiple adjustment rods that are adjusted by a sliding component, the adjustment rods are spaced apart, one end of the adjustment rod is hinged to the photovoltaic bracket, and the other end is hinged to the sliding component.

[0010] As a further embodiment of this utility model: the sliding assembly includes a fixed plate, a sliding rod, and multiple sliding sleeves connected to corresponding adjusting rods.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-7 A substation rooftop photovoltaic support foundation includes several longitudinal purlins 1 arranged at equal intervals. The purlins 1 can be installed on the side walls at both ends of the roof or installed through photovoltaic piers. The purlins 1 serve as the mounting base for the overall rooftop photovoltaic support foundation, used to fix all photovoltaic support foundation structures above them, and provide stable support for the subsequent assembly of various components.

[0026] Several sets of bearing bases 2 are provided above the purlin 1. Each set of bearing bases 2 is set above two adjacent purlins 1. The bearing bases 2 are connected to the purlins 1 through a pressing and fixing structure 3. The bearing bases 2 are rectangular frame structures. There are multiple sets of pressing and fixing structures 3, which are symmetrically arranged on the connecting rods of two bearing bases 2 parallel to the purlins 1. The pressing and fixing structures 3 on each side are equidistant along the vertical direction of the connecting rods.

[0027] like Figure 2-4 As shown, the pressing and fixing structure 3 includes a pre-tightening bracket 31 set on the top surface of the purlin 1, a pressing plate 32 set on the bottom surface of the purlin 1, and a pressing bolt 33 connecting the two. The pre-tightening bracket 31 has an L-shaped structure. Its vertical section is fixedly connected to the outer wall of the bearing base 2 by welding, and its horizontal section is set at the bottom of the bearing base 2. The horizontal section has two opposing first connecting holes 311, and the distance between the two first connecting holes 311 is greater than the width of the purlin 1. The pressing plate 32 has two second connecting holes 321 opposite to the first connecting holes 311. The pressing bolt 33 passes through the first connecting holes 311 and the second connecting holes 321 to fix the pre-tightening bracket 31 and the pressing plate 32 to the purlin 1, so as to install the bearing base 2 on the substation roof without penetration or damage.

[0028] A rubber buffer pad 34 is fixedly connected to the bottom surface of the pre-tightening bracket 31 and the top surface of the pressing plate 32. Several anti-slip protrusions 11 are provided on the upper and lower surfaces of the purlin 1. The rubber buffer pad 34 is tightly attached to the purlin 1 by tightening the pressing bolt 33, and is fixed by static friction to avoid penetration damage.

[0029] like Figure 1 and Figure 6As shown, a photovoltaic bracket 4 is hinged to the support base 2, and an adjustment mechanism 5 is provided between them. The photovoltaic bracket 4 has a rectangular frame structure, with mounting rods 41 at both ends of the horizontal side of the rectangular frame. The bracket is hinged to the outer walls of the support base 2 on both sides near the sunlight end via the mounting rods 41. The adjustment mechanism 5 includes two sets of adjustable structures for adjusting the angle of the photovoltaic bracket 4, which are arranged opposite to each other. The adjustable structures are equipped with fasteners 6 with locking functions. The two sets of adjustable structures are respectively arranged opposite to each other on the outer walls of the support base 2.

[0030] like Figure 5 As shown, in the first embodiment of this utility model, the adjustment structure includes multiple adjustment rods 51 that are adjusted by a sliding assembly. The adjustment rods 51 are spaced apart. One end of the adjustment rod 51 is hinged to the photovoltaic bracket 4, and the other end is hinged to the sliding assembly. The sliding assembly includes a fixed plate 52, a sliding rod 53, and multiple sliding sleeves 54 connected to the corresponding adjustment rods 51. There are two fixed plates 52, which are vertically fixedly connected to the side wall of the bearing base 2. The sliding rod 53 is fixedly connected between the two fixed plates 52. Multiple sliding sleeves 54 are sleeved on the sliding rod 53. The sliding sleeves 54 are slidably connected to the sliding rod 53. The sliding sleeves 54 correspond one-to-one with the adjustment rods 51. In this embodiment, there are two sliding sleeves 54 and two adjustment rods 51. The adjustment rod 51 is hinged to the side wall of the corresponding sliding sleeve 54.

[0031] Multiple first mounting holes 531 are equidistantly provided on the slide rod 53, extending from the top surface to the bottom surface of the slide rod 53. A second mounting hole 541 (not shown in the figure) is provided on the sliding sleeve 54, extending from the top surface to the bottom surface of the sliding sleeve 54. Fasteners 6 pass through the first and second mounting holes 531 and 541 to secure the sliding sleeve 54 to the slide rod 53. Tightening the fasteners 6 restricts the movement of the sliding sleeve 54 on the slide rod 53, ensuring the structural stability of the photovoltaic support 4.

[0032] like Figure 7As shown, in the second embodiment of this utility model, the adjustment structure includes multiple sets of telescopic rod assemblies spaced apart. One end of each telescopic rod assembly is connected to the photovoltaic bracket 4 via a hinge seat 56, and the other end is hinged to the bearing base 2. Each telescopic rod assembly includes an outer tube 57 with an internal cavity and a telescopic rod 58 disposed within the outer tube 57. The telescopic rod 58 is slidably connected to the outer tube 57. An annular limiting boss is provided on the inner wall of the outer tube 57 near the end of the telescopic rod 58. An annular stop is provided at the end of the telescopic rod 58 that extends into the outer tube 57, adapting to the limiting boss. The abutment between the limiting boss and the annular stop prevents the telescopic rod 58 from completely dislodging from the outer tube 57, ensuring sliding stability. Multiple third mounting holes 581 extending along the thickness direction are equidistantly provided on the telescopic rod 58, and a fourth mounting hole 571 extending along the thickness direction is provided on the outer tube 57 (not marked in the figure). Fasteners 6 pass through the third mounting holes 581 and the fourth mounting holes 571 to fix the outer tube 57 and the telescopic rod 58, so that the photovoltaic bracket 4 remains stable after the angle is adjusted.

[0033] The working principle of this utility model is as follows: First, purlins 1 are installed according to the actual structure of the roof. If the roof structure and distance allow for the installation of purlins 1, several purlins 1 can be installed equidistantly on the side walls at both ends of the roof; if not, photovoltaic piers can be used for installation. The photovoltaic piers are fixed first, and then the purlins 1 are connected and fixed to the photovoltaic piers, so that the purlins 1 form a stable installation base for the overall photovoltaic support foundation of the roof. Then, the bearing base 2 is installed and fixed to two adjacent purlins 1 by the pressing and fixing structure 3. The horizontal section of the pre-tightening bracket 31 is attached to the top surface of the purlin 1, and the pressing plate 32 is placed on the bottom surface of the purlin 1 corresponding to the position of the pre-tightening bracket 31. The pressing bolts 33 are passed through the first connecting hole 311 of the pre-tightening bracket 31 and the second connecting hole 321 of the pressing plate 32, and tightened to complete the assembly of the bearing base 2. When the angle of the photovoltaic support 4 needs to be adjusted according to different installation environments, it can be adjusted by the adjusting mechanism 5. When using the structure in the first embodiment of this patent, by pushing the sliding sleeve 54 to slide along the sliding rod 53, the sliding sleeve 54 drives the hinged adjusting rod 51 to move synchronously, thereby changing the tilt angle of the photovoltaic bracket 4. When the angle is adjusted to the preset value, the fastener 6 is passed through the first mounting hole 531 of the sliding rod 53 and the second mounting hole 541 of the sliding sleeve 54 and tightened to restrict the movement of the sliding sleeve 54 and achieve angle locking of the photovoltaic bracket 4. When using the structure in the second embodiment of this patent, the telescopic rod 58 is pulled or pushed to slide along the cavity of the outer tube 57. The angle of the photovoltaic bracket 4 is adjusted by the change in the length of the telescopic rod assembly. After the angle is determined, the fastener 6 is passed through the fourth mounting hole 571 of the outer tube 57 and the third mounting hole 581 of the telescopic rod 58 and tightened to fix the relative position of the outer tube 57 and the telescopic rod 58, ensuring that the photovoltaic bracket 4 maintains a stable angle.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
