Description

Technical Field

[0001] This utility model relates to the field of photovoltaic structure technology, and specifically to a marine photovoltaic support grid structure. Background Technology

[0002] Photovoltaic power generation is the most effective form of developing and utilizing solar energy resources today, and abundant solar energy resources provide favorable conditions for the development of photovoltaic power generation. At present, with the continuous growth of onshore photovoltaic installations, land resources and related policy restrictions are becoming key factors restricting the large-scale development of photovoltaics; therefore, offshore photovoltaics have begun to develop gradually.

[0003] Offshore photovoltaic grid structures are directly connected to offshore pile foundations. Typically, the cross-section of the grid members is smaller than that of the columns. Under load, the stress in the members at the connection between the grid and the top of the columns is relatively large. To reduce the stress in the members, methods such as increasing the number of columns and reducing the span of the grid are usually adopted. This results in low space and material utilization and increased project costs. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the prior art and provide a marine photovoltaic support grid structure to solve the problem of high engineering cost of traditional marine photovoltaic grid structures in the prior art.

[0005] To achieve the above objectives, this utility model provides a marine photovoltaic support grid structure for use in conjunction with marine pile foundations to provide support and installation positions for photovoltaic panels above the sea surface; the marine photovoltaic support grid structure includes:

[0006] The space frame platform is set above the sea surface and forms an installation plane above the sea surface through its own top.

[0007] The support column is connected at its bottom to the offshore pile foundation and at its top to the bottom of the space frame platform above the sea surface; at least three support columns are connected to the bottom of the space frame platform, and these three support columns are not on the same straight line.

[0008] The tensioning mechanism tensions two adjacent support columns, while simultaneously supporting the bottom of the space frame platform between these two support columns.

[0009] By adopting this technical solution, on the basis of the existing photovoltaic panel support structure composed of support columns and grid platform, a tensioning mechanism is set between adjacent support columns to tension the adjacent support columns, while providing support force to the bottom of the grid platform between the support columns. Without increasing the offshore pile foundation or reducing the support span of the support columns, the vertical stiffness of the grid platform is increased, and the internal force distribution is not concentrated near the support columns. This increases the stability of the entire support grid structure, reduces the project cost, and meets the actual stability requirements for use.

[0010] Furthermore, the space frame platform includes an upper space frame, a lower space frame, and diagonal braces;

[0011] Both the upper and lower space frames are composed of rods arranged in a grid pattern and connected to each other by ball bolts;

[0012] The diagonal brace is inclinedly installed between the upper and lower space frames, and its two ends are respectively connected to ball bolts on the upper and lower space frames at the corresponding positions.

[0013] By adopting this technical solution, the upper space frame, lower space frame, and diagonal braces can be connected by ball bolts to form a conventional four-corner pyramid space frame structure, which can ensure that the space frame platform itself has high structural strength and stability.

[0014] Furthermore, the support column is a tree branch column with a forked top, and each end of the forked top is connected to the bottom of the grid platform.

[0015] By adopting this technical solution, the support columns are set as tree branch columns, which can directly reduce the support span of the space frame platform, thereby improving the support stability of the space frame platform.

[0016] Furthermore, the tensioning mechanism includes support rods and cables; wherein,

[0017] The top of the support rod is connected to a ball bolt at a corresponding position on the lower space frame, and the lower end of the support rod is sleeved on the cable.

[0018] The two ends of the cable are respectively connected to two adjacent support columns, and the cable has tension prestress.

[0019] By adopting this technical solution, after the cable tensions two adjacent support columns, it can push the support members upward, thereby acting on the bottom of the space frame platform between adjacent support columns, so that the positions not supported by the support columns can be supported, which is equivalent to reducing the support span and thus improving the stability of the overall structure.

[0020] Furthermore, at least two support rods are provided between the cable between adjacent support columns and the bottom of the space frame platform.

[0021] By adopting this technical solution, increasing the number of support members can further reduce the support span of the space frame platform and further improve the overall structural stability.

[0022] Furthermore, the support rod includes four support rods connected at the bottom and forming an inverted cone shape.

[0023] By adopting this technical solution, the four inverted cone-shaped struts, after being connected to the ball bolts on the lower space frame, have high structural strength and stability. They can adapt to the upward supporting force generated by the tensioning of the cables, ensuring the stability of the corresponding force transmission, and thus ensuring the stability of the corresponding functions.

[0024] Compared with the prior art, this utility model has the following advantages:

[0025] Based on the existing photovoltaic panel support structure consisting of support columns and a grid platform, a tensioning mechanism is installed between adjacent support columns to tension the adjacent support columns, while simultaneously providing support force to the bottom of the grid platform between the support columns. Without increasing the offshore pile foundation or reducing the support span of the support columns, the vertical stiffness of the grid platform is increased, and the internal force distribution is not concentrated near the support columns. This increases the stability of the entire support grid structure, reduces the project cost, and meets the actual stability requirements for use. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Please see the appendix Figure 1 This utility model provides a marine photovoltaic support grid structure for use in conjunction with marine pile foundations to provide support and installation positions for photovoltaic panels 5 above the sea surface. The marine photovoltaic support grid structure includes: a grid platform 2, which is set above the sea surface and forms an installation plane above the sea surface through its top; support columns 1, whose bottom ends are connected to the marine pile foundations and whose top ends extend above the sea surface to connect to the bottom of the grid platform 2; at least three support columns 1 are connected to the bottom of the grid platform 2, and these three support columns 1 are not on the same straight line; a tensioning mechanism 3, which tensions two adjacent support columns 1 and simultaneously supports the bottom of the grid platform 2 between these two support columns 1.

[0031] Based on the existing photovoltaic panel 5 support structure consisting of support columns 1 and grid platform 2, a tensioning mechanism 3 is set between adjacent support columns 1 to tension the adjacent support columns 1, while providing support force to the bottom of the grid platform 2 between the support columns 1. Without increasing the marine pile foundation or reducing the support span of the support columns 1, the vertical stiffness of the grid platform 2 is increased, and the internal force distribution is not concentrated near the support columns 1, thereby increasing the stability of the entire support grid structure, reducing the project cost, and meeting the actual use stability requirements.

[0032] It should be noted that the grid platform 2 only provides support and installation position for the offshore photovoltaic panels 5, and does not directly support and install the photovoltaic panels 5. Specifically, when the photovoltaic panels 5 are actually installed on the grid platform 2, purlins 4 need to be installed on the grid platform 2 to provide direct support and installation for the photovoltaic panels 5.

[0033] The support column 1 should be installed in a one-to-one correspondence with the offshore pile foundation.

[0034] The space frame platform 2 includes an upper space frame, a lower space frame, and diagonal braces. Both the upper and lower space frames are composed of members arranged in a grid pattern and connected to each other by ball bolts. The diagonal braces are inclined between the upper and lower space frames, and their two ends are respectively connected to ball bolts on the upper and lower space frames at corresponding positions. The upper space frame, lower space frame, and diagonal braces can be connected by ball bolts to form a conventional four-corner pyramid space frame structure, which can ensure that the space frame platform 2 itself has high structural strength and stability.

[0035] Support column 1 is a tree branch column with a forked top, and each end of the forked top is connected to the bottom of the space frame platform 2. The tree branch column design of support column 1 can directly reduce the support span of the space frame platform 2, thereby improving the support stability of the space frame platform 2.

[0036] Please see the appendix Figure 2 The tensioning mechanism includes a support rod 31 and a cable 32. The top end of the support rod 31 is connected to a ball bolt at a corresponding position on the lower space frame, and the lower end of the support rod 31 is sleeved on the cable 32. The two ends of the cable 32 are respectively connected to two adjacent support columns 1, and the cable 32 has tension prestress. After the cable 32 tensions the two adjacent support columns 1, it can push the support rod 31 upward, thereby acting on the bottom of the space frame platform 2 between the adjacent support columns 1, so that the position not supported by the support column 1 can be supported, which is equivalent to reducing the support span, thereby improving the stability of the overall structure.

[0037] Furthermore, at least two support members 31 are provided between the cable 32 between adjacent support columns and the bottom of the space frame platform 2; increasing the number of support members 31 can further reduce the support span of the space frame platform 2 and further improve the overall structural stability.

[0038] Furthermore, the support member 31 includes four support rods connected at the bottom and forming an inverted cone shape. The four support rods, which are inverted cone shape, have high structural strength and stability after being connected to the ball bolts on the lower space frame. They can adapt to the upward supporting force generated by the tensioning of the cable 32, ensure the stability of the corresponding force transmission, and thus ensure the stability of the corresponding function.

[0039] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
