However, photovoltaic power generation devices are easily damaged by wind, especially in extreme weather such as hurricanes or strong winds, where photovoltaic supports and solar panels are easily damaged, affecting the stability and safety of photovoltaic power generation. In addition, the rear column of the photovoltaic support is a weak point that is prone to deformation during the use of the photovoltaic support. Therefore, a photovoltaic support is proposed to solve the above-mentioned problems. Utility Model Content

A Z-shaped crossbeam, diagonal brace, and crossarm are fixed between the front column and the rear column. A first support block is fixed between the crossarm and the upper clamp, and a second support block is fixed between the upper clamp and the lower clamp. The first and second support blocks are located on both sides of the PHC pipe pile. The top surface of the diagonal beam is used to fix the photovoltaic panel. The front diagonal support, the rear diagonal support, and the diagonal beam are arranged in a triangular pattern. One end of the front diagonal support and the rear diagonal support are respectively fixed to both ends of the diagonal beam, and the other end of the front diagonal support and the rear diagonal support are respectively fixed to both sides of the lower clamp.

[0007] In the above technical solution, both the first support block and the second support block are provided with fixing holes. The first support block is fixed to the front column by a bolt and nut structure that mates with the fixing hole, and the second support block is fixed to the rear column by a bolt and nut structure that mates with the fixing hole.

[0008] In the above technical solution, the upper clamp includes two upper half clamps. Each upper half clamp includes an upper arc portion and an upper connecting portion located at both ends of the upper arc portion and integrally formed with the upper arc portion. The upper connecting portion is provided with positioning threaded holes. Bolts pass through the positioning threaded holes and cooperate with nuts to fix the two upper half clamps together and clamp them onto the PHC pipe pile.

[0009] In the above technical solution, an upper reinforcing rib is provided between the upper arc portion and the upper connecting portion, and the thickness of the upper reinforcing rib is 5-10 mm.

[0010] In the above technical solution, the lower clamp includes two lower half clamps, each lower half clamp includes a lower arc portion and a connecting portion located at both ends of the lower arc portion and integrally formed with the lower arc portion. The connecting portion is provided with a first threaded hole and a second threaded hole respectively. The front column and the rear column are connected to the first threaded hole through a bolt and nut structure, and the front inclined support and the rear inclined support are connected to the second threaded hole through a bolt and nut structure.

[0011] In the above technical solution, a lower reinforcing rib is provided between the lower arc portion and the lower connecting portion, and the thickness of the lower reinforcing rib is 5-10 mm.

[0012] In another aspect of the present invention, a photovoltaic fixing system includes a plurality of wind-resistant and stable photovoltaic supports arranged in rows and a plurality of purlins, wherein the plurality of purlins are fixed in parallel to the inclined beams and the purlins are arranged in a grid pattern intersecting the inclined beams, and the photovoltaic panels are fixedly connected to the purlins.

[0013] In the above technical solution, the purlin is fixed to the inclined beam by a purlin bracket with an L-shaped cross section.

[0015] In the above technical solution, SC diagonal beam tie rods are fixed crosswise on the purlin, and the SC diagonal beam tie rods are connected to the purlin through tie rod corner braces or through fan-shaped washers.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model, by setting up Z-shaped crossbeams, diagonal braces, and crossarms between the front and rear columns, creates a more triangular stabilizing system between the front and rear columns, effectively dispersing and bearing wind loads, thereby improving the overall stability of the entire photovoltaic support system. Furthermore, in actual use, the rear column of the photovoltaic support is a weak point prone to deformation. By setting up Z-shaped crossbeams, diagonal braces, and crossarms, the support points on the upper side of the rear column can be increased, reducing the vibration and displacement of the photovoltaic support under wind force, preventing the photovoltaic support from twisting or falling off due to excessive wind force, making the photovoltaic support structure more rationally stressed, and avoiding deformation of the upper side of the column under wind loads.

[0018] 2. This utility model features a first support block fixed between the crossarm and the upper clamp, and a second support block fixed between the upper clamp and the lower clamp. The crossarm, upper clamp, lower clamp, first support block, and second support block form an S-shaped structure, thereby increasing the support points for the front and rear columns and optimizing the stress distribution. This significantly improves the wind resistance of the photovoltaic support system. Furthermore, the first and second support blocks allow the photovoltaic support system to disperse and balance external forces when subjected to wind, resisting the horizontal force and bending moment of wind loads and reducing the risk of deformation or breakage of the front and rear columns due to excessive force on one side. In addition, the support blocks enhance the horizontal stability of the support system, preventing the photovoltaic modules from shifting or falling off under strong winds. The S-shaped structure, with its symmetrical stress distribution through the support blocks on both sides, allows the support system to bear external forces more evenly under wind. This structural design helps reduce stress concentration in the support system, improving the overall durability and service life. The first and second support blocks can withstand greater wind loads with a smaller amount of steel structure, which is economical.

[0019] 3. This utility model, by setting up S-shaped and Z-shaped structures, can effectively disperse wind loads and improve the overall wind resistance of the photovoltaic support structure through their combined action. The two structures work together to form multiple support points, which can reduce the direct impact of wind on the photovoltaic modules, thereby reducing the risk of wind damage to the support structure.

[0042] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0043] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.
