[0002] Photovoltaic panels and other photovoltaic modules are typically supported by piers. If it's inconvenient to install expansion bolts on the roof of some houses, piers are often placed on the roof, and then the photovoltaic modules are installed on the neatly arranged piers. When deploying photovoltaic equipment on unpaved outdoor sites, piers are often buried in the foundation to improve the modules' wind and earthquake resistance. To enhance the overall structural strength of the piers, a steel skeleton is placed within them during casting. These skeletons are typically constructed by workers arranging and tying multiple cut steel bars according to design requirements, which can be cumbersome to operate. Utility Model Content

[0023] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application are clearly and completely described below. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts also fall within the scope of protection of this application.

[0024] like Figure 1 and Figure 2 As shown, this application discloses a skeleton structure for casting a photovoltaic module base pier, comprising a positioning base plate 1, an annular groove 2 is provided at the edge of the upper side of the positioning base plate 1, a cylindrical metal skeleton 3 made of rolled steel mesh is placed in the annular groove 2; a plurality of steel hoops 4 are sleeved on the outer side of the cylindrical metal skeleton 3, and the plurality of steel hoops 4 are evenly arranged on the outer side of the cylindrical metal skeleton 3 along its circumferential direction; a support assembly 5 is provided at the center of the positioning base plate 1, and the support assembly 5 can be connected to the photovoltaic module.

[0025] In the above embodiments, no matter the base of the photovoltaic module is cast on site or in a prefabrication plant, a steel skeleton needs to be laid out inside it in advance to ensure the overall stability of the base. These steel skeletons are usually made of multiple steel bars arranged as required and fixed with wire or welding materials. This skeleton is time-consuming and labor-intensive to produce.

[0026] When using the skeleton structure for the photovoltaic module base pier in the present application, it is only necessary to place the positioning base plate 1 to the specified position first, and then bend the sheet steel mesh along the annular groove 2 on the positioning base plate 1 to form a cylindrical metal skeleton 3 (in order to improve the stability of the cylindrical metal skeleton 3 after bending, the head and tail connections can be reinforced and tied with wire), and then the steel hoops 4 are put on the cylindrical metal skeleton 3 one by one, and the support assembly 5 is placed to complete the construction of the skeleton required for the entire photovoltaic base pier. Compared with the prior art method of placing and tying multiple steel bars one by one to build the photovoltaic base pier skeleton, the skeleton structure construction process of the present application is simpler and more convenient, which can effectively improve the casting efficiency of the photovoltaic module base pier and is also more convenient during transportation.

[0027] Furthermore, if Figure 1 and Figure 3As shown, the support assembly 5 includes a main sleeve 51, a sub-sleeve 52 is inserted into the main sleeve 51 and the two are slidably connected along the vertical direction, and a limiting unit 53 is provided on the outside of the top port of the main sleeve 51, which can limit the position of the sub-sleeve 52 in the main sleeve 51; a fixing plate 54 is installed on the top of the sub-sleeve 52.

[0028] In the above embodiment, the main sleeve 51 is placed on the positioning base plate 1. When concrete is subsequently poured on the cylindrical metal frame 3, the concrete rebounds and covers most of the main sleeve 51. After the concrete solidifies, the main sleeve 51 and the solidified concrete base pier can form a whole. In this way, the main sleeve 51 can be better fixed by the concrete base pier, and when the sub-sleeve 52 thereon provides support for the photovoltaic module, it has a good anti-overturning effect. The sub-sleeve 52 within the main sleeve 51 can slide up and down, and after sliding to a specified position, it can be fixed by the limit unit 53. In actual use, workers can flexibly adjust the length of the sub-sleeve 52 extending from the main sleeve 51 according to the height to be reached by the photovoltaic panel. The fixing plate 54 at the top of the sub-sleeve 52 is used to fix it to the connecting plate below the photovoltaic module leg, thereby installing the photovoltaic module on the base pier.

[0029] Furthermore, if Figure 3 As shown, the limiting unit 53 includes a plurality of threaded holes 531 evenly arranged along the outer side of the upper end of the main sleeve 51 , and an adjusting bolt 532 is threadedly connected in each threaded hole 531 .

[0030] In the above embodiment, when adjusting the relative position of the sub-sleeve 52 and the main sleeve 51 in the support assembly 5, the worker can loosen the multiple adjusting bolts 532 from the threaded holes 531 at their respective positions, so that the ends of the adjusting bolts 532 leave the surface of the sub-sleeve 52, thereby releasing the restriction on the position of the sub-sleeve 52 within the main sleeve 51. After the worker has adjusted the position of the sub-sleeve 52 within the main sleeve 51, the worker re-tightens the multiple adjusting bolts 532 one by one, so that their ends once again abut against the outer surface of the sub-sleeve 52. In this way, the multiple adjusting bolts 532 can re-secure the sub-sleeve 52 at the adjusted height. Controlling the state of the sub-sleeve 52 within the main sleeve 51 by adjusting the bolts 532 is simple and convenient.

[0031] Furthermore, if Figure 2 and Figure 3 As shown, a mounting sleeve 6 is welded at the center of the upper side of the positioning base plate 1 , and the inner diameter of the mounting sleeve 6 is equal to the inner diameter of the main sleeve 51 .

[0032] In the above embodiment, the installation sleeve 6 of the present application not only facilitates the rapid placement of the main sleeve 51 in the center of the positioning base plate 1, but also serves to limit the main sleeve 51 after it is inserted therein, thereby preventing the main sleeve 51 from shifting before the concrete in the cylindrical metal frame 3 solidifies.

[0033] Furthermore, if Figure 2 As shown, the area between the annular groove 2 and the mounting sleeve 6 on the positioning base plate 1 is a metal mesh structure.

[0034] In the above embodiments, if the base of the photovoltaic module is prefabricated in a unified manner in the production area, a mold will be arranged on the outside of the entire skeleton structure before pouring the concrete. In order to ensure that all components of the skeleton structure after pouring will not be exposed outside the concrete, the positioning base plate 1 will usually be erected between the bottom mold using concrete pads, and the side mold as a whole will be larger than the cylindrical metal skeleton. This application sets the area between the annular groove 2 of the positioning base plate 1 and the mounting sleeve 6 into a metal mesh structure to ensure that when pouring concrete, the concrete can quickly fill the space below the positioning base plate 1.

[0035] Furthermore, if Figure 2 As shown, a plurality of pulp passages 7 are evenly arranged on the circumference of the mounting sleeve 6 .

[0036] In the above embodiment, the slurry channel 7 arranged on the side of the installation sleeve 6 allows the concrete to be added to the cylindrical metal frame 3, and then the concrete can come into contact with the main sleeve 51 in the installation sleeve 6 through the slurry channel 7. In this way, after the concrete is subsequently solidified, the contact area between the main sleeve 51 and the concrete structure can be further increased, thereby improving the fixing effect and pull-out resistance of the main sleeve 51.

[0037] Furthermore, if Figure 3 As shown, the fixing plate 54 is circular, and a plurality of straight slot-shaped connecting through holes 8 are arranged in a circumferential array on the fixing plate 54 .

[0038] In the above embodiment, the shape of the connecting through hole 8 is a straight slot shape, so when the connecting plate on the photovoltaic module leg is installed on the fixing plate 54, Figure 5 As shown, as long as the connecting through hole 8 on the fixing plate 54 is aligned with the mounting hole on the connecting plate, connecting plates of various specifications can be installed on the fixing plate 54 of the present application, which effectively improves the applicability of the present application.

[0039] The implementation principle of this embodiment is as follows: when it is necessary to make the base of the photovoltaic module, the base template can be arranged at the designated location first. Then the base frame structure is assembled. When assembling the base frame, the worker first places the positioning base plate 1 in the designated area, and then bends and rolls the sheet-like steel mesh into a cylindrical metal frame 3 along the annular groove 2 on the positioning base plate 1, and then puts the steel hoop 4 on the cylindrical metal frame 3 one by one, and then places the support assembly 5 on the positioning base plate 1 to complete the construction of the skeleton required for the entire photovoltaic base. Compared with the prior art method of placing and tying multiple steel bars one by one to build the photovoltaic base frame, the skeleton structure construction process of this application is simpler and more convenient, which can effectively improve the casting efficiency of the photovoltaic module base, and is also more convenient during transportation.

[0040] Next, workers place concrete pads in the formwork and place the entire skeleton structure on the concrete pads, and then they can start pouring concrete. If the concrete pads have been tied to the bottom of the positioning base plate 1 in advance during the early stage of the bottom pier skeleton structure construction, there is no need to place concrete pads in the formwork. The entire skeleton structure can be directly placed in the bottom pier formwork for concrete pouring. Figure 4 After the concrete is poured and cured, the position of the sub-sleeve 52 in the main sleeve 51 can be adjusted, and then the photovoltaic module can be connected to the fixing plate 54 on the top of the sub-sleeve 52 (the connected photovoltaic module is as shown in FIG. Figure 5 shown).

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
