[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0023] Please refer to Figures 1 to 5As shown in the figure, a screw pile of a solar photovoltaic array integrated with a pile foundation in this embodiment includes a pile body 1, a threaded rod 3, a first nut 4, and a second nut 5. The pile body 1 is of a hollow structure. A spiral blade 2 is arranged on the outer circumference of the pile body 1. An internal thread is arranged in the hollow structure of the pile body 1. The lower end of the pile body 1 is pointed. The threaded rod 3 is inserted into the hollow structure from the upper end of the pile body 1 and is matched with the pile body 1 through threads. The first nut 4 and the second nut 5 are arranged on the upper part of the threaded rod 3. During use, first implant the pile body 1 into the soil to increase the stability and bearing capacity through the blade 2 on the pile body 1. Then, screw the threaded rod 3 into the pile body 1. The connecting piece of the solar photovoltaic panel is fixed between the first nut 4 and the second nut 5, and it can be clamped tightly through the second nut 5. With the screw pile of the solar photovoltaic array in this embodiment, there is no need for a concrete base, saving the time and cost of making the concrete base.
[0024] As Figure 3 shown, the lower end of the pile body 1 is provided with a separable expansion structure for pushing it to expand after the threaded rod 3 moves down to the bottom, so as to fix it in the soil. That is, similar to the structure of an expansion bolt, after it expands, it can be well fixed in the soil.
[0025] The first nut 4 can preferably be set as a square to facilitate the tightening operation; and the first nut 4 and the threaded rod 3 can also be set as an integral structure.
[0026] As Figure 4 shown, the size of the lower end portion 6 of the threaded rod 3 is larger than the size of the main body of the threaded rod 3. Through this design, it is beneficial for the expansion structure to expand in a larger range.
[0027] Again, as Figure 5 shown, the size of the blade 2 gradually decreases from top to bottom, making its load-bearing capacity and stability better and enabling it to penetrate into the ground better.
[0028] It should be noted that in this article, relative terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.
[0029] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
