Description

Technical Field

[0001] This utility model relates to a diagonal bracing structure for a marine photovoltaic bolted ball grid in high wind speed areas. Background Technology

[0002] Marine renewable energy is an important means to achieve the "3060 dual carbon" target. In recent years, offshore photovoltaic (PV) has continued to develop rapidly, with advantages such as open and unobstructed sea surface, abundant sunshine, no occupation of land resources, easy integration with other marine industries, and proximity to power load centers. However, offshore PV is affected by water depth, geological and marine hydrological conditions, which places higher technical requirements on PV support systems.

[0003] Offshore photovoltaic (PV) bolted ball grid structures, composed of rods and bolted ball joints, are a typical prefabricated structure with advantages in processing and assembly speed, as well as superior precision and quality control. Currently, many projects in northern China, such as Shandong and Hebei, utilize bolted ball grid structures. This structure features a short insertion section at the bottom of the grid, facilitating direct insertion of piles and welding connections. However, offshore PV sites may be located in high-wind-speed areas. Therefore, in high-wind-speed areas, without additional diagonal bracing at the pile tops, the piles in the PV support system will bear significant bending moments. To enhance the safety and reliability of the offshore PV support system, the specifications of the piles need to be increased, inevitably leading to increased pile costs. Furthermore, due to the large span of the bolted ball grid structure, excessive structural deflection is a common problem, limiting the development of offshore PV bolted ball grid structures in deep-water areas.

[0004] Therefore, a bolted ball grid structure for marine photovoltaic systems in high wind speed areas is proposed to address the above problems. Utility Model Content

[0005] The purpose of this utility model is to overcome the existing defects and provide a marine photovoltaic bolt ball grid inclined bracing structure for high wind speed areas, which significantly reduces the external load and engineering volume of the pile foundation and improves the overall economy of photovoltaic support and pile foundation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a marine photovoltaic bolt ball grid diagonal bracing structure in high wind speed areas, comprising diagonal bracing components and connecting components;

[0007] The upper end of the diagonal bracing assembly is connected to the bolt ball grid frame, and the lower end of the diagonal bracing assembly is connected to the connecting assembly, which is connected to the upper end of the steel pipe pile.

[0008] Preferably, the first bolt ball and three diagonal braces are connected; the lower ends of the three diagonal braces are connected to the first bolt ball, and the upper ends of the three diagonal braces are connected to the lower end face of the bolt ball frame.

[0009] The first bolt ball connects to the connecting assembly.

[0010] Preferably, the connecting assembly includes a plug rod, the upper end of which is connected to the first bolt ball, the lower end of which is an insertion section that is inserted into the upper port of the steel pipe pile, and the middle part of which is connected to a partition plate.

[0011] Preferably, the upper surface of the partition is connected to multiple support plates, and the multiple support plates are connected at equal intervals to the outer wall of the plug rod.

[0012] Preferably, the lower end face of the partition is welded to the upper end of the steel pipe pile.

[0013] Preferably, the diagonal bracing can be four or more.

[0014] Preferably, the photovoltaic panel is connected to the upper end of the bolted ball grid frame.

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: The upper grid structure of this offshore photovoltaic bolted ball grid structure in high wind speed areas uses bolted ball connections, and its foundation is a steel pipe pile foundation. By adopting a diagonal bracing structure, the external load on the pile foundation can be significantly reduced, and problems such as excessive deflection of the upper support can be effectively solved, thereby reducing the amount of work and lowering the project cost. The overall structure is quick and convenient to construct, especially in high wind speed offshore areas, where its advantages are even more significant. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 A bolted ball grid structure for offshore photovoltaic systems in high wind speed areas includes a bracing assembly and a connecting assembly. The upper end of the bracing assembly is connected to the bolted ball grid 1, and the lower end of the bracing assembly is connected to the connecting assembly, which is connected to the upper end of a steel pipe pile 2. Photovoltaic panels are connected to the upper end of the bolted ball grid 1.

[0025] Specifically, the bolted ball net frame consists of multiple upper chords, multiple lower chords, multiple web members, multiple upper bolted balls, and multiple lower bolted balls. The multiple upper chords are connected to form a square net through multiple upper bolted balls, the multiple lower chords are connected to form a square net through multiple lower bolted balls, and the multiple web members are obliquely arranged between two square nets, with their ends connected to the upper bolted balls and lower bolted balls respectively.

[0026] Specifically, there is a first bolt ball 3 and three diagonal braces 4; the lower ends of the three diagonal braces 4 are connected to the first bolt ball 3, and the upper ends of the three diagonal braces 4 are connected to the lower end face of the bolt ball frame 1; there can also be four or more diagonal braces 4. The first bolt ball 3 is connected to the connecting assembly.

[0027] Specifically, the connecting assembly includes a plug rod 5, with the upper end of the plug rod 5 connected to a first bolt ball 3, and the lower end of the plug rod 5 being an insertion section 6, which is inserted into the upper port of the steel pipe pile 2. A partition plate 7 is connected to the middle of the plug rod 5. Multiple support plates 8 are connected to the upper surface of the partition plate 7, and these support plates 8 are equidistantly connected to the outer wall of the plug rod 5. The lower surface of the partition plate 7 is welded to the upper port of the steel pipe pile 2.

[0028] Specifically, the prefabricated steel pipe piles 2 are transported to the offshore construction site for piling. The members of the bolt-ball space frame 1 are interconnected via bolt-ball joints and assembled in a land-based factory. Next, the diagonal bracing structure is installed. This diagonal bracing structure is triangular in shape, with its upper end connected to the bolt-ball space frame 1 via bolt-ball joints, and its lower part connected to the first bolt ball 3. The first bolt ball 3 connects to the insertion section structure, which includes a partition and an insertion section steel pipe. After installation, the entire structure is transported to the site. The lower diagonal bracing structure of the bolt-ball space frame 1 is inserted into the steel pipe piles 2 and then welded together on-site. After welding, the bolt-ball space frame and the steel pipe pile foundation form a unified whole, thus completing the installation of the entire support system.

[0029] The marine photovoltaic bolted ball grid structure in this high-wind-speed zone utilizes bolted ball connections for the upper grid structure, with a steel pipe pile foundation. The use of a diagonal bracing structure further reduces the external load on the pile foundation and effectively solves problems such as excessive deflection of the upper support, thereby reducing the amount of work and lowering project costs. The overall structure is quick and easy to construct, especially in high-wind-speed marine areas where its advantages are even more pronounced.

[0030] In this high-wind-speed zone, the inclined bracing structure of the offshore photovoltaic bolted ball grid effectively reduces the horizontal bending moment caused by wind loads by adding an inclined bracing structure between the bolted ball grid and the pile foundation. This significantly reduces the amount of pile foundation work and improves the overall economic efficiency of the photovoltaic support and pile foundation. Furthermore, the inclined bracing structure increases the number of support points for the upper grid, effectively reducing the grid span, solving the problem of excessive structural deflection, and reducing the required pile foundation specifications, thereby lowering the project cost.

[0031] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
