A photovoltaic support structure

Abstract

This application discloses a photovoltaic support structure, relating to the photovoltaic field. The photovoltaic support structure includes a clamping mechanism, a support rod, a base mechanism, and a support mechanism. During installation, two semi-clamps are fastened to the outer periphery of the pile foundation by a first fastening component. The support rods connect the semi-clamps and the base respectively. If the pile foundation deviates horizontally, the position of the base can be adjusted. If the elevation of the pile foundation deviates, shims can be placed between the base and the column base plate to compensate for the height difference. The photovoltaic support structure of this application does not require additional positioning auxiliary devices and has the function of adjusting the plane position and elevation to adapt to the construction deviation of the pile foundation. Compared with traditional technology, it is not necessary to correct the position and elevation of each rod individually. The base rests against the top of the pile foundation, and the connection of each part is bolted, eliminating the need for hot work. The adjustment of the pile foundation construction deviation is completed during the installation of this photovoltaic support structure, significantly improving work efficiency.

Description

Technical Field

[0001] This application relates to the field of photovoltaics, and more particularly to a photovoltaic support structure. Background Technology

[0002] For pile foundations used in photovoltaic support systems, small deviations are inevitable during construction, given the current level of construction technology. Current construction specifications require that the allowable deviations be: pile top elevation deviation 0 to -10mm and pile position deviation ±30mm.

[0003] In existing technologies, to accommodate deviations in pile foundation construction, oblong holes are typically designed at each bolted joint of the support structure for bolt fastening. While this method can accommodate deviations in pile foundation construction, regardless of whether the work surface is assembled piece by piece or pre-assembled and installed on site, the position and elevation of each member need to be corrected individually. This results in varying degrees of cumbersome operation and low construction efficiency, or the need for additional auxiliary positioning devices for adjustment. Utility Model Content

To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0032] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0033] like Figure 1 and Figure 2 As shown in the figure, this embodiment discloses a photovoltaic support structure, which includes a clamping mechanism 100, a support rod 200, a base mechanism 300, and a support mechanism 400.

[0034] like Figure 3 As shown, the clamping mechanism 100 includes two half-clamps 110 and a first fastening component 120. There are two half-clamps 110, symmetrically arranged, each with an arc shape. Both ends of each half-clamp 110 have connecting ears 111. The first fastening component 120 passes through the connecting ears 111 of the two half-clamps 110, connecting and locking the two half-clamps 110 together at two locations. The two half-clamps 110, when connected, form a ring-shaped clamp, which is used to clamp the outer circumference of the pile foundation 500. In this embodiment, the first fastening component 120 is preferably a combination of bolts and nuts.

[0035] like Figure 3As shown, a first square tube 130 is provided on the outer circumference of the semi-hoop 110. The axial direction of the first square tube 130 is aligned with the height direction. A first square hole 130a is provided inside the first square tube 130, which is a through hole along the height direction. A second square tube 140 is also provided on the outer circumference of the semi-hoop 110. The axial direction of the second square tube 140 is aligned with the height direction. A second square hole 140a is provided inside the second square tube 140, which is a through hole along the height direction.

[0036] like Figure 2 and Figure 3 As shown, in this embodiment, the first square tube 130 facilitates a stable connection with the lower end of the support rod 200, and the second square tube 140 facilitates engagement with the mating rod 360 of the base 310. On one hand, this limits the mating rod 360 to sliding adjustment only in the first horizontal direction. On the other hand, after the horizontal positions of the base 310 and the mating rod 360 are adjusted, a first shim 370 is filled between the mating rod 360 and the second square hole 140a to stabilize the position of the base 310. Furthermore, the square hole in this embodiment is a through-hole design, which prevents water and dust accumulation.

[0037] like Figure 3 As shown, along the arc of the semi-hoop 110, the first connecting ear 111, the first square tube 130, the second square tube 140, and the second connecting ear 111 are sequentially arranged. The included angle between the first connecting ear 111 and the first square tube 130 is 45 degrees, and the included angle between the first square tube 130 and the second square tube 140 is 45 degrees. From a top view, the two first square tubes 130 of the clamping mechanism 100 are symmetrically arranged about the second horizontal direction, and the two second square tubes 140 of the clamping mechanism 100 are symmetrically arranged about the first horizontal direction. The first and second horizontal directions intersect perpendicularly in the horizontal plane.

[0038] like Figure 2 As shown, the support rod 200 is a square prism. The lower end of the support rod 200 is inserted into the first square hole 130a. Preferably, the size of the support rod 200 matches the inner circumference of the first square hole 130a, preventing the support rod 200 from moving or rotating horizontally within the first square hole 130a. The support rod 200 is vertically positioned. A first aperture is provided at the upper end of the support rod 200, with its axial direction aligned in a first horizontal direction. The first screw 320 of the base mechanism 300 passes through the first aperture. A fourth aperture is provided at the lower end of the support rod 200, with its axial direction aligned in a second horizontal direction. A second fastening assembly 150 passes through the first square tube 130 and the fourth aperture along the second horizontal direction, connecting the support rod 200 to the first square tube 130. The second fastening assembly 150 is configured as a conventional bolt and nut combination.

[0039] like Figure 2 As shown, in some preferred embodiments, a stop block 210 is also provided on the side of the support rod 200 facing the pile foundation 500. The stop block 210 can abut against the outer circumference of the pile foundation 500. When the support rod 200 is under force, the stop block 210 abuts against the pile foundation 500 to ensure the stability of the support rod 200.

[0040] like Figure 2 As shown, the base mechanism 300 includes a base 310, a first screw 320, a second screw 330, a first locking nut 340, and a second locking nut 350.

[0041] The base 310 is circular in shape, and its axis is parallel to the axis of the clamping mechanism 100. After installation, the base 310 fits against the top surface of the pile foundation 500.

[0042] like Figure 2 As shown, one end of the first screw 320 is fixedly connected to the upper surface of the base 310. A reinforcing rib is provided between the first screw 320 and the base 310 to ensure the strength and stability of the first screw 320. The axial direction of the first screw 320 is configured in a first horizontal direction, and the first screw 320 passes through a first aperture at the upper end of the support rod 200 along the first horizontal direction. In this embodiment, there are two first screws 320, symmetrically arranged at both ends of the base 310 about a second horizontal direction, with the axial directions of the two first screws 320 coinciding (the axial direction of the first screw 320 is the first horizontal direction).

[0043] like Figure 2 As shown, in this embodiment, the first screw 320 and the support rod 200 are arranged in a one-to-one correspondence. The two support rods 200 are respectively connected to the first square tube 130 of the two half-hoops 110. The support rod 200 is provided with a first light hole, which can restrict the first screw 320 and the base 310 to move horizontally relative to the clamping mechanism 100 in the first horizontal direction, thereby adjusting the horizontal deviation caused by the construction of the pile foundation 500. On the other hand, by cooperating with the support rod 200 and the first screw 320, the entire clamping mechanism 100, the support rod 200 and the base mechanism 300 can be pre-assembled together and then fitted onto the pile foundation 500 as a whole, which greatly improves the construction efficiency.

[0044] like Figure 4As shown, the second screw 330 is vertically mounted on the base 310, and its lower end is fixedly connected to the base 310. A second light hole is provided on the column base plate 420 of the support mechanism 400. The second screw 330 passes coaxially upward through the second light hole, thereby achieving a limiting connection between the column base plate 420 and the base 310. Preferably, in this embodiment, there are multiple second screws 330. This embodiment illustrates four second screws 330 spaced apart on the base 310 along the height direction.

[0045] like Figure 2 As shown, the first locking nut 340 is threaded onto the first screw 320, and the first locking nut 340 is located on the outside of the support rod 200, that is, the first locking nut 340 is located on the side of the support rod 200 away from the base 310 along the first horizontal direction. Both first screws 320 are threaded with the first locking nut 340. After the base 310 and the first screws 320 are adjusted to their positions in the first horizontal direction, the first locking nuts 340 restrict the first screws 320 and the base 310 from moving freely in the first horizontal direction, thereby locking the base 310 in the first horizontal direction.

[0046] like Figure 2 As shown, the second locking nut 350 is threaded onto the second screw 330. The second locking nut 350 is located on the upper side of the column base plate 420. By screwing the second locking nut 350 downwards, the column base plate 420 is pressed together with the base 310, thereby achieving the locking of the column base plate 420 in the height direction.

[0047] In other words, this embodiment is designed so that the first locking nut 340 and the second locking nut 350 can lock the base 310 and the column foot plate 420 respectively in the first horizontal and vertical directions after the position deviation adjustment is completed, so as to ensure structural stability.

[0048] like Figure 2 As shown, in this preferred embodiment, the base mechanism 300 is provided with two mating rods 360. The two mating rods 360 are symmetrically arranged at both ends of the base 310 about the first horizontal direction. The mating rods 360 extend vertically downward and can be inserted downward into the second square hole 140a of the second square tube 140. The mating rods 360 can slide in the second square hole 140a along the first horizontal direction. The lower end of the mating rod 360 is provided with a light hole. The third fastening component 160 passes through the second square tube 140 and the light hole of the mating rod 360 along the first horizontal direction and connects the mating rod 360 and the second square tube 140 together through the third fastening component 160. In this embodiment, the two mating rods 360 are inserted one-to-one with the second square tubes 140 on the two half-hoops 110.

[0049] like Figure 7As shown, in this embodiment, the mating rod 360 mates with the second square tube 140, which increases the connection stability between the half-hoop 110 and the base 310. After the base 310 is adjusted, a first shim 370 can be filled between the second square hole 140a and the mating rod 360, preventing the mating rod 360 from sliding relative to the second square hole 140a, thereby restricting the base 310. In this embodiment, preferably, a third light hole is provided on the first shim 370, through which the third fastening component 160 passes, preventing the first shim 370 from deviating. The third fastening component 160 is configured as an existing bolt and nut combination.

[0050] like Figure 4 As shown, in some preferred embodiments, the base mechanism 300 further includes a second shim 380, which is configured as a rectangular piece. The second shim 380 is disposed between the upper surface of the base 310 and the column base plate 420. If there is a deviation in the elevation of the pile foundation 500 (generally, the height of the pile foundation will only be lower than the design height), the second shim 380 is superimposed between the base 310 and the column base plate 420 to compensate for the height difference. If there is no elevation deviation in the pile foundation 500, there is no need to fill the second shim 380. In this embodiment, preferably, the second shim 380 is provided with a light hole through which the second screw 330 passes, which can limit the horizontal position of the second shim 380 and prevent it from deviating.

[0051] like Figure 1 As shown, the support mechanism 400 includes a support body 410 and a column base plate 420. The support body 410 is used to install photovoltaic modules (such as photovoltaic panels). The support body 410 includes structures such as columns, diagonal beams, and diagonal braces, which are existing technologies and will not be described in detail here. The column base plate 420 is fixedly connected to the lower end of the column of the support body 410. The column base plate 420 is provided with a plurality of second optical holes for correspondingly connecting with the second screws 330.

[0052] The construction steps in this embodiment are as follows:

[0053] I. For example Figure 5 As shown, after the pile foundation 500 was completed, a re-measurement was carried out, and the center line of the photovoltaic array's long axis (i.e., axis A) was marked on the top of the pile. Figure 5 ① to ⑨ represent the measured deviations in horizontal position and top elevation of piles ① to ⑨, respectively. For example: Figure 6 As shown, the pile position deviates from axis A by X mm (mm: millimeter) and the pile top elevation deviates by -Z mm.

[0054] 2. The lower end of the support rod 200 is locked together with the first square tube 130 of the clamping mechanism 100 through the second fastening component 150. The first light hole at the upper end of the support rod 200 is connected to the first screw 320 on the base 310. The base 310 and the clamping mechanism 100 are pre-connected through the support rod 200. Then the clamping mechanism 100 is installed on the pile foundation 500. The top surface of the half hoop 110 of the clamping mechanism 100 is a certain distance lower than the top surface of the pile foundation 500.

[0055] III. Figure 7 As shown, the position of the base 310 is adjusted in the first horizontal direction according to the principle of aligning the center line L of the base 310 with the axis A. Then, the first shim 370 is filled in the empty space between the mating rod 360 and the second square hole 140a. The third fastening assembly 160 passes through the second square tube 140 and the first shim 370 and is locked. Then, the first locking nut 340 is threaded onto the first screw 320 to lock the base 310.

[0056] IV. Figure 4 As shown, according to the elevation deviation, the corresponding second shim 380 is superimposed on the upper surface of the base 310. Then, the column base plate 420 of the bracket mechanism 400 is aligned with the base 310, the second light hole on the column base plate 420 is aligned with the second screw 330 and inserted, and then the column base plate 420 is locked on the base 310 by the second locking nut 350, thus completing the installation.

[0057] The above description is merely a specific implementation of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
