Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grounding piles, in particular to a grounding pile for photovoltaic power generation. Background Art
[0002] The main function of the grounding pile is to ensure a stable connection between the photovoltaic bracket and the ground, thereby effectively conducting the electricity generated by the photovoltaic panels into the power grid. In this process, the grounding pile also undertakes safety protection functions such as lightning protection and leakage protection. In lightning weather conditions, the grounding pile can lead lightning into the ground to avoid damage to the photovoltaic system; at the same time, when the photovoltaic system has a leakage, the grounding pile can also promptly conduct the leakage current into the ground to prevent electric shock accidents. The grounding pile is generally buried to a certain depth underground to ensure good contact with the soil. In order to ensure the conductive performance of the grounding pile, its surface is usually specially treated, such as galvanizing or spraying conductive paint.
[0003] For example, a photovoltaic power generation installation pile disclosed in the authorization announcement number CN217974341U includes a ground pile, the bottom end of the ground pile is fixedly connected to a connecting block, the bottom of the connecting block is fixedly connected to a limiting drill bit, the inner wall of the ground pile is movably connected to the foundation pile body, the bottom end of the ground pile is fixedly connected to a grounding plate, and the top of the grounding plate is removably provided with a positioning pin. The photovoltaic power generation installation pile has the characteristic of high stability through the arrangement of ground piles, connecting blocks, limiting drill bits, pile bodies, grounding plates, positioning pins, fixing blocks, screws, nuts, electric push rods, first clamps and second clamps. However, this technical solution requires that the ground piles be pre-installed on the pile body of the photovoltaic bracket during use, and then the ground piles and the pile body of the photovoltaic bracket are driven into the soil using a limiting drill bit to achieve the purpose of grounding and conductivity. However, it is difficult to apply to already installed photovoltaic brackets, that is, since the photovoltaic bracket has been fixed and installed on the ground, if you want to install a grounding pile on its pile body and use a limiting drill bit to drive it into the soil, it will not only require additional construction space, but will also cause damage to the already installed bracket structure. Utility Model Content

[0018] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0019] See also Figure 1-5 The utility model provides an embodiment: a grounding pile for photovoltaic power generation, comprising an angle seat 1 and connecting plates 2 and a limiting plate 3 respectively fixed on the outer walls on both sides of the angle seat 1. A trapezoidal cutout groove 4 is provided on the outer wall of the limiting plate 3 away from the connecting plate 2. The upper and lower surfaces of the angle seat 1 are both provided with U-shaped stud bolts 5. The top and bottom ends of the angle seat 1 are both equipped with double-headed screwing structures 7 that cooperate with the threaded ends of the U-shaped stud bolts 5. Since the size specifications of the photovoltaic bracket foundation piles may vary depending on various factors such as project requirements, geographical location, and soil conditions, the design of the trapezoidal cutout groove 4 allows the limiting plate 3 to match foundation piles of different sizes, thereby avoiding the tedious process of replacing the limiting plate 3 due to inconsistent foundation pile sizes, greatly simplifying the installation steps;
[0020] An I-shaped plate 6 is bolted to the outer wall of the connecting plate 2 on the side away from the corner seat 1. A support column 8 is installed on one side of the bottom end of the I-shaped plate 6, and a copper-plated grounding rod 9 is installed at the bottom end of the support column 8. The copper-plated material on the copper-plated grounding rod 9 has good electrical conductivity and can effectively conduct the static charge generated by the photovoltaic system into the ground, preventing static electricity accumulation from damaging the system;
[0021] The double-ended screwing structure 7 includes a limit seat 701 installed at the top and bottom ends of the angle seat 1. The front and rear ends of the limit seat 701 are fixed with a protruding column 702. The outer circumference of each end of the U-shaped stud bolt 5 is provided with an external thread groove 501. The two ends of the U-shaped stud bolt 5 pass through the outside of the protruding column 702 and are installed with a nut sleeve 703.
[0022] When the U-shaped stud bolt 5 is connected to the double-headed screwing structure 7, the threaded end of the U-shaped stud bolt 5 is screwed into the boss 702, and then the worker simultaneously screws the two nut sleeves 703. The nut sleeves 703 continuously tighten the U-shaped stud bolt 5 until the U-shaped stud bolt 5 rests against the outer wall of the foundation pile. The double-headed screwing structure 7 makes the installation process simpler and improves on-site construction efficiency.
[0023] The angle seat 1 and the limit plate 3 are both made of stainless steel. Stainless steel has high strength and can withstand a certain amount of pressure and weight.
[0024] A rectangular block 601 is fixed on both sides of the bottom end of the I-shaped plate 6. An internal threaded hole 603 is provided inside the rectangular block 601. A positioning bolt 602 that is threadedly matched with the rectangular block 601 is installed on the outer wall of one side of the connecting plate 2. When the I-shaped plate 6 is connected to the connecting plate 2, the staff will fit the back of the I-shaped plate 6 and the rectangular block 601 on the outer wall of one side of the connecting plate 2, and then drive the positioning bolt 602 into the internal threaded hole 603 to tighten the connecting plate 2 and the rectangular block 601, thereby ensuring a firm connection between the copper-plated grounding rod 9 and the connecting plate 2 and the angle seat 1, reducing safety hazards caused by loose connections;
[0025] The length of the copper-plated grounding rod 9 is 0.3 m to 1 m. A grounding rod of sufficient length can better guide the current into the ground, thereby ensuring the effectiveness of the grounding system.
[0026] When the embodiment of the present application is in use, the staff first takes out the angle seat 1 and the U-shaped stud 5 in the grounding pile. At this time, the U-shaped stud 5 is connected with the double-headed screwing structure 7, that is, the angle seat 1 and the limit plate 3 form a groove that can be embedded with the photovoltaic bracket through the trapezoidal cut-out groove 4. Then the staff clamps the angle seat 1 and the limit plate 3 on the outer wall of the base pile of the photovoltaic power generation bracket through the trapezoidal cut-out groove 4. When the angle seat 1 and the limit plate 3 are adjusted with the base pile, the staff takes out the two U-shaped studs 5 so that the threaded ends of the U-shaped studs 5 are connected with the double-headed screwing structure 7 until the double-headed screwing structure 7 rests on the outer wall of the base pile, thereby completing the grounding pile and the base pile. The pile is initially assembled. At this time, the staff bolts an I-plate 6 on the outer wall of one side of the connecting plate 2, that is, the copper-plated grounding rod 9 is connected to the connecting plate 2 through the I-plate 6. Finally, the staff drives the copper-plated grounding rod 9 into the soil, thereby completing the connection between the grounding pile and the photovoltaic power generation bracket. This structural design allows the grounding pile to be effectively installed after the photovoltaic bracket is installed, thereby improving the flexibility and applicability of the grounding pile installation. The combined use of the U-shaped stud bolt 5, the limit plate 3, and the double-headed screwing structure 7 ensures a firm connection between the grounding pile and the photovoltaic bracket base pile, and not only provides sufficient mechanical strength, but also ensures the stability and reliability of the grounding pile.
[0027] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
