Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic construction, and in particular relates to a supporting and fixing structure and a photovoltaic bracket. Background Art

[0002] As the nation's carbon peak and carbon neutrality goals advance, efforts to build a new power system dominated by renewable energy are accelerating. The photovoltaic industry's status has significantly improved, ushering in historic development opportunities. Photovoltaic projects are experiencing ultra-rapid growth. To reduce the installed cost of photovoltaic power generation, the construction of photovoltaic power generation systems requires careful consideration of the site's topography, climate, and solar resource conditions, and the proper orientation and spacing of photovoltaic modules to achieve optimal power generation efficiency. As a crucial component of photovoltaic power generation systems, photovoltaic mounts are supporting structures that arrange photovoltaic modules in a specific orientation and angle and at fixed spacing. These structures directly impact the operational safety, damage rate, and construction investment of photovoltaic modules. Using appropriate photovoltaic mounts for different installation environments can not only reduce project costs but also subsequent maintenance costs. In the southwestern region, where sunlight resources are relatively abundant, the terrain is mostly mountainous, with uneven terrain and complex conditions. To fully utilize land resources, single-column fixed mounts are often used in mountainous areas. For example, Chinese utility model patent publication number CN206313716U discloses a mountain-type cast-in-place pile adjustable column photovoltaic power station bracket. This bracket uses a single column as its fixing unit, adapting to complex and uneven mountain terrain and effectively improving construction efficiency. However, single-column brackets have poor stability and are prone to tilting due to uneven force, making them unsuitable for supporting multiple photovoltaic arrays over a long period of time and resulting in high maintenance costs. Utility Model Content

[0003] In view of this, the purpose of the present invention is to provide a supporting and fixing structure to solve the technical problem of poor stability of the single-column bracket proposed in the background art.

[0004] The utility model discloses a supporting and fixing structure, which comprises an end unit, a column and a stay cable assembly;

[0005] The end unit includes compression piles, pull-out piles and connecting beams;

[0006] The two ends of the connecting beam are respectively connected to the top ends of the compression pile and the pull-out pile;

[0007] The upright column is vertically connected to the top of the compression pile;

[0008] One end of the stay cable assembly is connected to the top of the pull-out pile, and the other end is connected to the top of the column.

[0009] Compared with the existing single-line stress-bearing single column form, the supporting fixing structure provided by the utility model is a right-angled triangle structure composed of compression piles, pull-out piles, connecting beams and inclined cable assemblies. The stress-bearing structure is stable and not prone to tilting.

[0010] Furthermore, the top elevations of the connecting beam, the compression piles and the pull-out piles are equal.

[0011] Furthermore, the compression piles and the pull-out piles are cast-in-place concrete piles; the connecting beam, the compression piles and the pull-out piles are cast in one piece.

[0012] Furthermore, the compression pile includes a first steel cage, a first concrete and bolts;

[0013] The first steel cage is arranged inside the first concrete;

[0014] One end of the bolt is inserted and connected to the first steel cage, and the other end of the bolt passes through the top of the compression pile and is connected to the column.

[0015] Furthermore, the stay cable assembly includes a pre-buried fixing, a stay cable and a main cable connected in sequence, and the pull-out pile includes a second steel cage and a second concrete;

[0016] The second steel cage is arranged inside the second concrete;

[0017] The embedded fixing piece is arranged at the bottom of the second reinforcement cage;

[0018] One end of the stay cable is connected to the embedded fixing piece, and the other end of the stay cable passes through the second steel cage and the top of the pull-out pile and is connected to the bottom end of the main cable;

[0019] The top end of the main cable is connected to the top end of the column.

[0020] Furthermore, the embedded fixing part includes a steel plate and an extrusion anchor, and one end of the inclined cable passes through the steel plate and is connected to the extrusion anchor.

[0021] Furthermore, the stayed cable assembly further includes a sleeve, which is sleeved on the main cable and is arranged on the top of the pull-out pile.

[0022] The utility model also provides a photovoltaic bracket, which includes a double array of the supporting and fixing structures described above.

[0023] The two sets of supporting and fixing structures in the photovoltaic bracket cooperate with each other, and the photovoltaic components are placed on two sets of right-angled triangles composed of the supporting and fixing structures. The force-bearing structure is more stable and suitable for long-term support of multiple photovoltaic arrays.

[0024] Furthermore, the supporting and fixing structures are parallel to each other.

[0025] Furthermore, the connecting beam is perpendicular to the slope of the mountain.

[0026] The utility model has the following beneficial effects:

[0027] 1) The supporting and fixing structure provided by the present invention is stable and reliable. Each end unit is composed of a combination of a compression pile, an anti-pulling pile and a connecting beam. The compression pile and the anti-pulling pile are connected as a whole by a connecting beam. The compression pile provides the vertical support force of the column to the photovoltaic module. The anti-pulling pile improves the lateral stability of the compression pile through the tension generated by the inclined cable assembly. The connecting beam supports and fixes the compression pile and the anti-pulling pile. Compared with the single column form of single-line force, the supporting and fixing structure provided by the present invention is a right-angled triangle force structure composed of compression piles, anti-pulling piles, connecting beams and inclined cable assemblies. The force is stable and not prone to tilting. The photovoltaic bracket provided by the present invention is composed of two groups of supporting and fixing structures that cooperate with each other. The photovoltaic modules are placed on the two groups of right-angled triangles composed of the supporting and fixing structures. The force structure is more stable and suitable for long-term support of multiple photovoltaic arrays.

[0028] 2) The supporting fixed structure provided by this utility model has strong terrain adaptability and low cost. The compression and pull-out piles in the end units are cast-in-place concrete piles, which are constructed using a crawler drilling rig. Compared with traditional independent foundation supports, the cast-in-place concrete piles use less raw materials and shorten the construction time. The end units are highly adaptable to complex mountainous terrain, and drilling is easy, eliminating the need for large-scale excavation, making construction quick and efficient.

[0029] 3) The support and fixing structure provided by the present invention has high connection strength. The compression piles are pre-embedded with bolts, one end of which penetrates and connects to the steel cage within the compression piles, while the other end is connected to the column, thus enhancing the connection strength between the column and the compression piles. The pull-out piles are pre-embedded with diagonal cables connected to the main cables. One end of the diagonal cables is connected to the pre-embedded fixings within the pull-out piles, enabling them to withstand the greater tension transmitted by the main cables. This increases the pulling strength of the pull-out piles on the columns, resulting in a high connection strength for the entire support.

[0030] 4) The support and fixing structure provided by this utility model is durable and easy to maintain. The cable assembly adopts a two-stage connection method of the cable and the main cable. The cable and the pull-out pile end are provided with a sleeve to reduce the wear between the cable and the pull-out pile, thus avoiding the subsequent maintenance and repair caused by wear. Only the main cable of the cable assembly needs to be maintained and repaired.

[0031] 5) The support and fixing structure provided by this utility model is highly flexible and adaptable. The length and specifications of the compression piles, pullout piles, and connecting beams can be adjusted on-site to ensure the stability of the overall structure based on the geological conditions of the construction site, the span of the installed photovoltaic modules, and the required wind resistance performance. This makes the photovoltaic support structure suitable for a variety of terrain environments. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] In some other embodiments provided by the present invention, the connecting beam 130 is integrally cast with the compression piles 110 and the pull-out piles 120. This eliminates the need for additional construction equipment and processes, allowing for simple construction and a single, integrated structure with high structural strength. Preferably, the top elevations of the connecting beam 130, compression piles 110, and pull-out piles 120 are equal, further simplifying the integral casting process.

[0062] In some embodiments of the present invention, the connecting beam 130 is perpendicular to the slope of the mountain. In this embodiment, the length and specifications of the compression piles 110, the pull-out piles 120, and the connecting beam 130 can be adjusted on-site based on the geological conditions of the construction site, the span of the installed photovoltaic panels, and the required wind resistance to ensure the stability of the overall structure, making it suitable for various terrain environments.

[0063] In some embodiments provided by the present invention, the compression pile 110 includes a first steel cage 111, a first concrete 112, and a bolt 113. The first steel cage 111 is disposed within the first concrete 112. One end of the bolt 113 is inserted and connected to the first steel cage 111, and the other end of the bolt 113 passes through the top of the compression pile 110 and is connected to the column 200. The compression pile 110 is pre-embedded with the bolt 113. One end of the bolt 113 is inserted and connected to the first steel cage 111 within the compression pile 110, and the other end is connected to the column 200, thereby improving the connection strength between the column 200 and the compression pile 110.

[0064] In some embodiments provided by the present invention, the inclined cable assembly 300 includes an embedded fixing 310, an inclined cable 320 and a main cable 330 connected in sequence, and the pull-out pile 120 includes a second steel cage 121 and a second concrete 122; the second steel cage 121 is arranged inside the second concrete 122, and the embedded fixing 310 is arranged at the bottom of the second steel cage 121 and can be connected to the second steel cage 121; one end of the inclined cable 320 is connected to the embedded fixing 310, and the other end of the inclined cable 320 passes through the second steel cage 121 and the top of the pull-out pile 120 and is connected to the bottom end of the main cable 330; the top of the main cable 330 is connected to the top of the column 200. The pre-embedded inclined cable 320 in the pull-out pile 120 is connected to the main cable 330. One end of the inclined cable 320 is connected to the main cable 330 through the pre-embedded fixing 310 set at the bottom of the second steel cage 121, so that it can withstand the large tensile force transmitted by the main cable 330. This improves the pulling strength of the pull-out pile 120 on the column 200, making the connection strength of the entire bracket high.

In combination with the above two embodiments, the inclined cable assembly 300 adopts a two-stage connection method of the inclined cable 320 and the main cable 330. A sleeve 340 is set at the exposed end of the inclined cable 320 and the pull-out pile 120 to reduce the wear between the inclined cable 320 and the pull-out pile 120, avoiding the subsequent maintenance and repair caused by wear.
