Abstract
Description
Technical Field
[0001] This utility model relates to a tree stump-type base component and its photovoltaic support, belonging to the field of ground piles. Background Technology
[0002] With the increasing global demand for clean energy, photovoltaic (PV) power generation has been widely adopted as a sustainable energy source. PV support systems, as crucial structures supporting PV modules, typically use either driven-in columns or helical piles as their foundations. However, these conventional foundation types require specialized construction equipment, making them unsuitable for small-scale or remotely accessible projects. Therefore, this tree stump-style PV column fixing system was designed. It can be installed using common and portable equipment, and the length of the inclined tube can be freely adjusted to suit different application scenarios, filling technological gaps in certain usage scenarios.
[0003] The prior art discloses a tree-shaped ground pile with publication number CN203977413, which includes a column, a flange for installing the top of the column, and multiple limiting sleeves for limiting the installation position of the reinforcing bars. The limiting sleeves are evenly distributed around the column and obliquely welded to the outer surface of the column side wall. However, the existing technology has a relatively simple method of fixing the steel bars and the limiting sleeve, which is prone to loosening due to external forces or vibrations, affecting the overall stability and service life of the photovoltaic support. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tree stump-type base component and its photovoltaic support to solve the problem.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a tree stump-type base assembly, including a base, a limiting sleeve, and a beveled circular tube inserted into the limiting sleeve; the limiting sleeves are evenly distributed around the base and obliquely welded to the base; it also includes a limiting component and a positioning element; The limiting component is installed on the limiting sleeve and acts on the obliquely cut round tube to fix the obliquely cut round tube to the limiting sleeve; Several positioning elements are provided and fixed to the outside of the base. The positioning elements are used to position the base during construction and prevent the base from tipping over.
[0006] Preferably, the limiting component includes a nut fixed on the limiting sleeve and a bolt threadedly connected to the nut; the bolt is inserted into the limiting sleeve and abuts against the obliquely cut circular tube.
[0007] Preferably, each of the limiting sleeves is provided with at least one limiting component.
[0008] Preferably, the base is a hollow rectangular tubular structure with several mounting grooves distributed on one wide side for accommodating photovoltaic bracket assembly.
[0009] Preferably, the positioning element is welded to the short side of the outer side of the base.
[0010] Preferably, the positioning element is parallel to the long axis of the base.
[0011] A photovoltaic bracket is installed in the base by means of hardware components.
[0012] Beneficial effects The limiting component of this utility model can firmly fix the obliquely cut round tube in the limiting sleeve, effectively preventing the obliquely cut round tube from shifting or shaking during use, and ensuring the stability and reliability of the photovoltaic bracket support structure. The positioning components solve the problem of difficult base positioning during construction, and can effectively prevent the base from tipping over, thus enhancing safety during construction and overall stability after installation. Attached Figure Description
[0013] Other features, objects, and advantages of this invention will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings: Figure 1 This is a structural schematic diagram of a tree stump-type base component and its photovoltaic support according to the present invention; Figure 2 This is a schematic diagram of the photovoltaic bracket of this utility model installed on the module; Figure 3 A schematic diagram of existing technology. Detailed Implementation
[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0015] Please see Figure 1 This utility model provides a technical solution for a tree stump-type base assembly: including a base 1, a limiting sleeve 2, and a beveled circular tube 3 inserted into the limiting sleeve 2; the limiting sleeves 2 are evenly distributed around the base 1 and obliquely welded to the base 1; the base 1 serves as the basic load-bearing component, and the limiting sleeves 2 are obliquely welded around the base 1 and evenly distributed to accommodate the inclined insertion requirements of the beveled circular tube 3, allowing the beveled circular tube 3 to be installed at a suitable angle. In one embodiment, there are 4 limiting sleeves 2, and the beveled circular tube 3 is inserted into the limiting sleeve 2, which can achieve ground support of the photovoltaic bracket through cooperation with the limiting sleeve 2.
[0016] It also includes limit components and positioning parts 5; In order to fix the obliquely cut round tube 3 to a certain extent within the limiting sleeve 2 and prevent it from shifting or shaking during use, a limiting component is provided; in one embodiment, the limiting component is installed on the limiting sleeve 2 and acts on the obliquely cut round tube 3 to fix the obliquely cut round tube 3 to the limiting sleeve 2.
[0017] Considering the actual needs during construction, the installation position of the positioning base 1 needs to be determined, and the base 1 needs to be effectively prevented from tilting. Positioning components 5 will be provided. In one embodiment, two positioning components 5 are provided, which are made of steel bars and fixed to the outside of the base 1. The positioning components 5 are used to position the base 1 during construction and prevent the base 1 from tilting.
[0018] Furthermore, the limiting component includes a nut 41 fixed on the limiting sleeve 2 and a screw 42 threadedly connected to the nut 41; the screw 42 is inserted into the limiting sleeve 2 and abuts against the obliquely cut circular tube 3. The length of the obliquely cut circular tube 3 relative to the ground within the limiting sleeve 2 is adjusted by tightening the screw 42, thereby fixing the obliquely cut circular tube 3 based on the position of the screw 42 and the limiting sleeve 2.
[0019] To ensure the fixing strength of the obliquely cut circular tube 3, each of the limiting sleeves 2 is provided with at least one limiting component. In one embodiment, multiple limiting components are provided to enhance the fixing effect between the limiting sleeve 2 and the obliquely cut circular tube 3.
[0020] Preferably, the base 1 is a hollow rectangular tubular structure with several mounting slots 11 distributed on one wide side for accommodating photovoltaic bracket assembly. On the one hand, the hollow structure reduces the overall weight while ensuring the structural strength of the base 1; on the other hand, the rectangular tubular structure has good stability, providing a solid foundation for the modules. The mounting slots 11 meet the installation requirements of the photovoltaic bracket.
[0021] Preferably, the positioning element 5 is welded to the short side of the outer side of the base 1. The positioning element 5 is parallel to the long axis of the base 1. This ensures that the force direction of the positioning element 5 is consistent with the installation direction of the base 1, facilitating its upright standing on the ground after installation.
[0022] See Figure 2 A photovoltaic bracket, wherein the photovoltaic bracket 6 is installed in the base 1 by means of hardware components.

It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
