[0001] The present application relates to the technical field of photovoltaic support, in particular to a column base assembly of photovoltaic support. BACKGROUND
[0002] With the continuous development and application of photovoltaic technology, the performance and efficiency of photovoltaic support system, as an important part of photovoltaic power station, are increasingly concerned. The photovoltaic support system is mainly composed of roof skeleton, waterproof skeleton and support skeleton, etc. Among them, the support skeleton, as the main load-bearing part, is usually formed by several columns arranged at intervals.
[0003] In the traditional scheme, as shown in Figure 1 , it is necessary to weld the fittings such as square tube 1', bottom plate 2' and stiffener plate 3' together at the construction site to form a column that can be supported on the ground, welding points a and b. In the welding process, it is troublesome to fix the position of the square tube, which needs to be located at the middle position of the bottom plate. This way not only has a long construction period, high labor cost, but also requires high technical level of construction workers.
[0004] In addition, the welding points are exposed and are easily affected by environmental factors such as moisture and corrosion, thereby affecting the stability and service life of the entire support system, and also affecting the aesthetics. SUMMARY
[0005] The purpose of the present application is to provide a column base assembly of photovoltaic support, which can realize quick and reliable connection of the column and the base, solve the problem of low construction efficiency of the traditional structure, and improve the stability and aesthetics of the entire support system.
[0006] To achieve the above purpose, the solution of the present application is: a column base assembly of photovoltaic support, comprising a column, a base, a fastener and an end cover, the upper end of the column is used to connect the beam of the roof skeleton, and the lower end of the column is connected with the base and supported on the ground;
[0007] The base comprises a bottom plate and a plug-in column vertically arranged on the bottom plate, the plug-in column is integrally formed with the bottom plate, the middle part of the plug-in column is a hollow structure for inserting the column, and the side wall of the plug-in column is provided with a mounting hole, after the column is inserted into the plug-in column, the fastener is used to cooperate with the mounting hole to fix the column; the outer side of the plug-in column and the bottom plate are provided with a stiffener plate inclinedly supported therebetween; and the end cover covers the base to hide it.
[0008] Further, the plug-in column is enclosed by four side plates vertically arranged on the bottom plate, and the mounting hole is formed in the plate wall of the side plate.
[0009] Further, the mounting hole is formed in at least one pair of opposite side plates.
[0010] Furthermore, mounting holes are provided on all four side plates.
[0011] Furthermore, the upper end of the column is provided with a U-shaped mounting groove for the beams of the roof frame to be embedded, and the side wall of the U-shaped mounting groove is provided with mounting holes.
[0012] Furthermore, the fastener is a bolt and nut assembly.
[0013] Furthermore, the end cap has a through hole in the middle for the column to pass through.
[0014] Furthermore, the end cap is generally in the form of a trapezoidal platform structure.
[0015] Furthermore, positioning holes are provided around the base plate, which are used to cooperate with fasteners to fix the base to the ground or a designated platform.
[0016] Furthermore, the positioning hole is a runway hole.
[0017] After adopting the above solution, the beneficial effects of the present invention are as follows:
[0018] The independent base, welded from a bottom plate, side plates, and stiffening plates, possesses strong stability. After prefabrication in the factory, the base is transported to the site for assembly with the columns. During assembly, workers simply insert the columns into the base's connectors, align the mounting holes, and then tighten them with fasteners to easily secure the base to the columns. This process significantly reduces on-site welding, simplifying the connection between the base and columns, significantly improving construction efficiency, effectively reducing labor costs, and ensuring the overall stability of the structure.
[0019] After the position of the column is determined and fixed, the end cap is put into the column and then placed on the base to hide the connection between the base and the column. This not only protects the fasteners and reduces the risk of them being corroded by rainwater and exposed to sunlight, but also makes the power station more aesthetically pleasing.

[0031] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0032] This invention provides a column base assembly for a photovoltaic support, such as... Figures 2 to 5 As shown, it comprises four independent parts: column 1, base 2, fastener 4, and end cap 5. The upper end of column 1 is used to support the roof frame, while the lower end is connected to base 2 and supported on the ground or a designated platform.
[0033] like Figure 2 As shown, the upper end of the column 1 has a U-shaped mounting groove 11, the size of which matches the size of the beams of the roof frame. The side wall of the U-shaped mounting groove 11 has mounting holes 3. During construction and assembly, the beams of the roof frame are embedded in the mounting groove of the column 1, and then fastened by fasteners 4 in conjunction with the mounting holes 3, thus connecting and fixing the beams to the column 1. The entire process eliminates the need for cumbersome welding operations that may pose safety hazards.
[0034] As shown in Figure 3, the base 2 includes a base plate 21 and a vertically mounted insertion post on the base plate 21. The middle part of the insertion post is a hollow structure for inserting the column 1. In this embodiment, the insertion post is formed by four vertical side plates 22. When the column 1 is inserted into the insertion post, the outer side wall of the column 1 and the inner side wall of the insertion post are in close contact, ensuring the stability and load-bearing capacity of the structure.
[0035] The side plate 22 has mounting holes 3 on its wall that can mate with the fastener 4, and at least one pair of opposite side plates 22 have mounting holes 3. The lower end of the column 1 has a hole corresponding to the mounting holes 3. The fastener 4 described in this invention is preferably a bolt 41 and nut 42 set.
[0036] To further enhance the stability of the base 2 structure, stiffening plates 23 are provided between the outer side of the side plate 22 of the insertion column and the base plate 21. These stiffening plates 23 are inclined and supported between the side plate 22 and the base plate 21. One side plate 22, one stiffening plate 23, and the base 2 form a stable triangular structure, effectively distributing the force and enhancing the overall load-bearing capacity. The upper end of the stiffening plate 23 is lower than the position of the mounting hole 3, so as not to obstruct or interfere with the use of the mounting hole 3.
[0037] In the base 2 structure described in this case, the side plates 22 and stiffening plates 23 are integrally formed on the base plate 21. These components are first welded in the factory, and then the entire base 2 structure is transported to the construction site for assembly with the columns 1, eliminating the need for on-site welding, which greatly simplifies the construction process and improves efficiency. This prefabricated production method not only saves time and costs associated with on-site welding but also helps improve project quality and safety.
[0038] The assembly process of column 1 and base 2 is as follows: Figure 5 As shown, first insert the lower end of the column 1 into the plug-in post, aligning the hole on the column 1 with the mounting hole 3 on the side plate 22. Then, pass the bolt 41 through the mounting hole 3 on one side of the base 2 through the hole in the column 1, and then through the mounting hole 3 on the other side. Tighten the nut 42 to complete the connection and fixation between the column 1 and the base 2. Here, to improve the stability of the assembly, mounting holes 3 can also be opened on all four side plates 22, and then two sets of fasteners 4 can be used to lock the column 1 all around, further reducing the risk of collapse caused by the column 1 shaking or tilting.
[0039] like Figure 4 As shown, the base plate 21 has positioning holes 24 around its perimeter. These holes 24 are used to engage with fasteners 4 to fix the base 2 to the ground or a designated platform. To provide greater installation flexibility and adjustment space, the positioning holes 24 are designed in the shape of runway holes. The runway hole design allows for fine-tuning within a certain range to adapt to different installation conditions and uneven ground, thereby ensuring that the base 2 can be installed stably and accurately.
[0040] like Figure 2 and Figure 5 As shown, the end cap 5 has a through hole 51 in the middle for the column 1 to pass through. The end cap 5 has a trapezoidal structure that is narrower at the top and wider at the bottom. After the position of the column 1 is determined and fixed, the end cap 5 is placed on the column 1. The end cap 5 can slide up and down along the column 1, and slide down to fasten and hide itself on the base 2. This not only protects the fasteners 4 and reduces the risk of corrosion from rainwater and exposure to sunlight, but also makes the power station more aesthetically pleasing. During assembly, the end cap 5 can be slid upwards to expose the base 2 without affecting construction.
[0041] In this case, the beams of the roof frame refer to diagonal beams or horizontal beams. In this embodiment, the diagonal beams, horizontal beams, and columns 1 are respectively made of square tubing with specifications of 50x100, 40x80, and 100x100 mm. However, this is only one embodiment and should not be taken as a limitation of this case. The specifications of the diagonal beams, horizontal beams, and columns 1 can be freely selected according to actual needs.
[0042] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention, primarily used to illustrate the embodiments and to explain the operating principles of the embodiments in conjunction with the relevant descriptions in the specification. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components. Furthermore, the front, back, left, and right orientations involved in this embodiment are only for reference and do not represent the orientation in actual application.
[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the design of this case. All equivalent changes made based on the key design features of this case shall fall within the protection scope of this case.
