Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically to a centralized fixed grid-connected photovoltaic support. Background Technology

[0002] Solar energy, as an inexhaustible and clean energy source, has spurred the vigorous development of the photovoltaic industry. The Hexi Corridor, in particular, boasts unique geographical advantages such as abundant solar resources, flat land, and low vegetation cover, making it a popular location for numerous large-scale grid-connected photovoltaic power plants. In the entire photovoltaic power generation system, the photovoltaic support structure, as a key component supporting the photovoltaic modules, requires a tilt angle designed to be fixed according to the latitude and longitude of the power plant location to ensure efficient power generation.

[0003] However, the current fixed photovoltaic support structures on the market are complex and use concrete as a base. Since large-scale centralized grid-connected photovoltaic power plants require a large number of fixed photovoltaic supports, the manufacturing and installation costs of the supports have increased significantly. Secondly, due to the complex structure and excessive weight of the photovoltaic supports, the support connectors are prone to fatigue damage under strong winds or rain and snow loads, which further increases the operation and maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a centralized fixed grid-connected photovoltaic support system to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A centralized fixed grid-connected photovoltaic support system includes:

[0007] The base includes an upper base and a lower base, wherein the lower base is a helical pile structure and helical blades are provided on the helical pile body;

[0008] The first support rod and the second support rod are embedded in the upper part of the base and fixed by a fixing shim.

[0009] A fixed inclined shaft is connected to the upper part of the first support rod, the upper part of the second support rod, and the upper part of the reinforcing rod respectively through connectors;

[0010] A fixed horizontal axis is installed equidistantly above a fixed oblique axis.

[0011] The reinforcing rod has its lower part connected to the first support rod via a circular clamp, and its upper part connected to the fixed inclined shaft via a connector.

[0012] Wherein, both the fixed oblique axis and the fixed horizontal axis are The structure has equidistant bolt holes on the bottom horizontal surface and a downwardly inclined baffle on the inner side wall of the top. Single-sided and double-sided pressure blocks for fixing photovoltaic modules are installed on the fixed horizontal axis by bolts.

[0013] The base has three threaded openings on its upper part, and is reinforced by bolts passing through the intersection of the support rod and the base.

[0014] There is a height difference between the first support rod and the second support rod, which causes the fixed inclined axis to form a preset tilt angle.

[0015] The connector is provided with a hinge point, and the upper part of the first support rod and the upper part of the second support rod are respectively embedded in the hinge point and fixed by bolts.

[0016] The inner diameter of the circular clamp matches the outer diameter of the first support rod, and the lower part of the reinforcing rod is fastened by bolts.

[0017] The connector also includes an upper surface with two bolt holes. The upper surface of the connector abuts against the bottom horizontal surface of the fixed inclined shaft when the connector is installed.

[0018] The width of both the single-sided and double-sided pressure blocks is smaller than the width of the groove on the fixed horizontal axis. An "L"-shaped fixing plate is fixedly installed on the single-sided and double-sided pressure blocks, extending upward from the side closest to the photovoltaic module.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0020] 1) The base of this utility model adopts a spiral pile structure, which drives the pile into the ground through rotary drilling. The depth of the base can be adjusted according to the terrain, so even if the terrain of the installation area is complex, the photovoltaic support can be kept at the same level. In addition, the base installation process does not require large mechanical equipment, has little impact on the surrounding environment, and is fast. It has the characteristics of universality for building large-scale centralized grid-connected photovoltaic power stations in different terrains;

[0021] 2) The main structure of this utility model consists of a base, a support rod, a reinforcing rod, and a fixed shaft. The structural design is simple and reasonable, and it can withstand the weight of the photovoltaic module, wind load, snow load, and other external forces, ensuring that the photovoltaic module maintains safe and stable operation under various environmental conditions. At the same time, it is convenient for later operation and maintenance, which greatly saves labor costs.

[0022] 3) By adopting a fixed inclined shaft and a fixed horizontal shaft with an upper opening and a downward tilting baffle, this utility model not only reduces the overall weight and facilitates transportation and installation, but also prevents the single-sided pressure block and the double-sided pressure block from accidentally detaching, effectively improving the stability of photovoltaic module installation.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0036] like Figure 1-10 As shown, the centralized fixed grid-connected photovoltaic support according to this utility model includes: a base 1, a first support rod 2, a second support rod 3, a fixed inclined shaft 4, a fixed horizontal shaft 5, a reinforcing rod 6, a connector 7, a circular clamp 8, a single-sided pressure block 9, and a double-sided pressure block 10.

[0037] Each base 102 has a helical pile structure with helical blades. The pile is vertically driven into the ground via rotary drilling, with the depth determined by the terrain of the installation area, ensuring that each base 101 is at the same horizontal level. Following the optimal inclination angle, the lower parts 201 and 302 of the first and second support rods are vertically embedded into the upper parts 101 of the base 1. Fixing shims 203 are provided on the lower parts 201 and 301 to secure their embedment into the upper parts 101. An opening is provided at the perpendicular intersection of the upper parts 101 and the lower parts 201 and 301. Bolts pass through these openings. The upper parts 101 also have three threaded openings; screwing the bolts into these openings reinforces and supports the connection between the base 1 and the first and second support rods.

[0038] The inner diameter of the circular clamp 8 is the same as the outer diameter of the first support rod 2. The extended portions at both ends of the circular clamp 8 are fastened with bolts, thereby fixing the circular clamp 8 to the first support rod. At the same time, the lower part 601 of the reinforcing rod is aligned with the mounting hole on the circular clamp 8 and connected with bolts.

[0039] The connector 7 is a U-shaped channel steel structure with triangular sides. The apex of the triangular side is the connector hinge point 701, which has a through hole. The bottom plane of the U-shaped channel steel is the upper plane 702 of the connector. The upper plane 702 of the connector has two bolt holes. The installation angle of each connector 7 is adjusted to the optimal tilt angle through the connector hinge point 701. When the connector 7 is installed, the upper plane 702 of the connector abuts against the bottom horizontal surface of the fixed inclined shaft 4 and is fixed with bolts. The upper part 202 of the first support rod and the upper part 302 of the second support rod are elliptical structures, and the upper part 602 of the reinforcing rod is rectangular. The upper parts 202 of the first support rod, the upper part 302 of the second support rod, and the upper part 602 of the reinforcing rod are respectively embedded in the connector hinge point 701 and fixed with bolts.

[0040] The height difference between the first support rod 2 and the second support rod 3 ensures that the fixed inclined shaft 4 achieves the optimal tilt angle. Both the fixed inclined shaft 4 and the fixed horizontal shaft 5 are... The structure, namely the fixed inclined shaft 4 and the fixed horizontal shaft 5, is a U-shaped structure. A downwardly sloping baffle is provided on the inner wall of the top opening end, and equidistant bolt holes are provided on the bottom horizontal surface. Four equidistant fixed horizontal shafts 5 are installed above the fixed inclined shaft 4 and fixed with bolts. By using fixed inclined shafts 4 and fixed horizontal shafts 5 with top openings and downwardly sloping baffles, not only is the overall weight reduced, facilitating transportation and installation, but it also prevents the single-sided pressure block 9 and the double-sided pressure block 10 from accidentally detaching, effectively improving the stability of the photovoltaic module 11 installation.

[0041] A single-sided pressure block 9 and a double-sided pressure block 10 for fixing the photovoltaic module 11 are bolted and installed on the fixed horizontal axis 5. The width of the single-sided pressure block 9 and the double-sided pressure block 10 is smaller than the width of the groove on the fixed horizontal axis 5, so that the single-sided pressure block 9 and the double-sided pressure block 10 can be embedded into the fixed horizontal axis 5 by bolts, which can effectively prevent the single-sided pressure block 9 and the double-sided pressure block 10 from detaching from the fixed horizontal axis 5. An "L"-shaped fixing plate is fixedly provided on the single-sided pressure block 9 and the double-sided pressure block 10 near the side of the photovoltaic module 11, and the photovoltaic module 11 can be pressed and installed on the fixed horizontal axis 5 by the "L"-shaped fixing plate.

[0042] In use, the single-sided pressure block 9 is installed on the edge of the photovoltaic module 11, corresponding to the bolt holes on the horizontal surface of the fixing axis 5, and is fixed to the side of the photovoltaic module 11 by bolts. The double-sided pressure block 10 is installed at the splicing point of two adjacent photovoltaic modules 11, engaging the frame groove of the photovoltaic module 11, corresponding to the bolt holes on the horizontal surface of the fixing axis 5, and is fixed by bolts to ensure that the two photovoltaic modules 11 are tightly connected, thereby making the photovoltaic module 11 securely installed on the entire bracket.
