[0002] In recent years, with the important layout of the national new energy strategy, the development of photovoltaic power generation has been getting faster and faster, but photovoltaic power generation has currently encountered its own bottleneck. With the gradual reduction of traditional photovoltaic land use and the warning of the red line of cultivated land quantity, the applicable scope of traditional photovoltaics is also getting narrower and narrower. Offshore photovoltaics well solve the drawback of traditional photovoltaic power generation occupying more land. The ocean area is vast, the applicable scope of photovoltaics is wide, there are no obstacles in the sky, the solar energy utilization efficiency is high, and the offshore photovoltaic power generation efficiency is 30% higher than that of onshore photovoltaic power generation. It is an important area for the future development of the photovoltaic industry. At the same time, there are significant differences between the offshore photovoltaic pile foundations and support systems and conventional onshore photovoltaic brackets. Their single set of bracket sizes are large, the pile foundation spacing is large, and the support structure is greatly affected by the marine environment. Similar structures have never been applied in the same environment, and there is no engineering practice in China and even worldwide.

[0003] The factors that have a greater destructive impact of the marine environment on the photovoltaic structure include the following aspects: the action of sea breeze on the photovoltaic panels, the influence of wave current, salinity, and sea ice on the piles, the settlement displacement of the pile foundations, the deformation of the pile foundations and brackets, the internal force changes within various structures and between structures under the action of various external factors, the structural vibration influence caused by sea breeze, etc. Therefore, it is very important to extract in real time the changes of photovoltaic panels, brackets, and pile foundations in the natural environment under various external forces for monitoring and early warning, and to make structural optimization adjustments for the influence of the marine environment on the photovoltaic structure.

[0037] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further introduced in detail below in conjunction with the accompanying drawings.

[0038] Please refer to Figure 1-6 , an offshore centralized photovoltaic detection and early warning operation platform, including a pile foundation 1 and a support frame 2 supported by the pile foundation 1. Here, the pile foundation 1 is a steel pile at the sea surface position, and the support frame 2 is a steel structure frame. Photovoltaic panels are laid above the support frame 2, and a deformation prevention support structure is arranged below the support frame 2. The support frame 2 with a large area is strengthened through the deformation prevention support structure to improve the structural stability in various marine environments. A support adjusting pile is arranged at the top of the pile foundation 1, and the support adjusting pile is used to support the bottom of the deformation prevention support structure. When the settlement of the pile foundation 1, the deformation of the support frame 2 and the deformation prevention support structure cause the support stress at the position of the support adjusting pile to change, the support height is adjusted through the support adjusting pile to restore the support stress on the deformation prevention support structure. Furthermore, after local deformation or stress change of the operation platform, through the support adjustment of the support adjusting pile, the support stress is restored within the preset range, thereby ensuring the long-term stability of the structure of the operation platform and improving the service life. Further, it also avoids frequent replacement of the pile foundation 1 and frequent maintenance of the support frame 2, so as to reduce the later maintenance cost of the offshore centralized photovoltaic detection and early warning operation platform;

[0039] The support adjusting pile includes a support part and an adjusting part. The adjusting part adjusts the support height in the axial direction relative to the support part to restore the support stress on the deformation prevention support structure. When the support stress is balanced, the relative position between the support part and the adjusting part is fixed to maintain this balanced state, so that the offshore centralized photovoltaic detection and early warning operation platform can resume normal use.

[0040] Furthermore, the deformation prevention support structure includes a longitudinal frame body 3. The longitudinal frame bodies 3 are multiple groups arranged in parallel below the support frame 2. The longitudinal frame bodies 3 provide structural support for the support frame 2 in the extending direction of the longitudinal frame bodies 3 to ensure structural stability. A transverse frame body 4 is arranged between every two adjacent groups of longitudinal frame bodies 3. The transverse frame body 4 is inclined to the longitudinal frame body 3 to provide structural support for the support frame 2 in the extending direction of the transverse frame body 4 to ensure structural stability;

[0041] The longitudinal frame body 3 and the transverse frame body 4 are both supported by pile foundations 1 below, so that each main stress-bearing part below the longitudinal frame body 3 and the transverse frame body 4 is supported by the pile foundation 1, in order to provide more stable support for the support frame 2.

[0042] Furthermore, the longitudinal frame body 3 is a support frame structure with an overall triangular shape, and the transverse frame body 4 is a triangular truss structure. By utilizing the stability of the triangular structure, stable support is provided for the support frame 2, reducing the probability of structural deformation of the support frame 2 in its plane.

[0043] Furthermore, the support part includes a support column 5. A flange connection is made between the bottom of the support column 5 and the top of the pile foundation 1 to provide a margin for the upper support structure in case of settlement of the pile foundation 1 or the like through the support column 5.

[0044] Furthermore, the adjustment part includes an adjustment sleeve 6. The adjustment sleeve 6 is sleeved on the support column 5 and axially slides on the support column 5;

[0045] The outer side of the adjustment sleeve 6 is fixedly connected to the longitudinal frame body 3 and the transverse frame body 4 by arranging side wing plates;

[0046] An adjustment mechanism is arranged between the adjustment sleeve 6 and the support column 5 to drive the adjustment sleeve 6 to axially move relative to the support column 5 and position the position after movement.

[0047] Specifically, by axially sliding the adjustment sleeve 6 on the support column 5, the margin of the support structure provided by the support column 5 is utilized to make up for the change in stress in case of settlement of the pile foundation 1 or the like, so as to maintain the stress balance of the support for the support frame 2. And this adjustment process is driven by the adjustment mechanism to make the adjustment sleeve 6 axially move relative to the support column 5 and position the position after movement, and maintain a balanced support state to continue to maintain the stability of the support for the support frame 2.

[0048] Furthermore, the adjustment mechanism includes a bottom support ring 7. The bottom support ring 7 is fixedly arranged around the bottom of the support column 5. A plurality of tightening bolts 8 are circumferentially arranged on the bottom support ring 7 to be tightened on the bottom surface of the adjustment sleeve 6. The tightening bolts 8 pass through the bottom support ring 7 and are in threaded cooperation with the bottom support ring 7;

[0049] An assembly plate 9 is arranged above the support column 5. A plurality of connecting rib plates 10 are circumferentially arranged between the lower surface of the assembly plate 9 and the outer surface of the upper end of the adjustment sleeve 6. An internally threaded pipe fitting 11 is arranged through the center position of the assembly plate 9. A threaded rod 12 that is in threaded cooperation with it is arranged inside the internally threaded pipe fitting 11. The lower end of the threaded rod 12 is tightened on the upper end surface of the support column 5.

[0050] Specifically, when performing the stress balance adjustment operation through the adjustment mechanism, first use a tool to rotate the threaded rod 12. Under the action of the threaded fit between the threaded rod 12 and the internally threaded pipe fitting 11, the lower end of the threaded rod 12 abuts against the upper end surface of the support column 5. Supported by the assembly plate 9 and the connecting rib plate 10, it is equivalent to the threaded rod 12 pushing the support column 5 to move axially downward. However, the actual moving part is the adjustment sleeve 6, and the adjustment sleeve 6 is connected to each component of the anti-deformation support structure to achieve the effect of jacking up each component of the anti-deformation support structure. This process can be carried out slowly to detect the stress change of the pile foundation 1 or the support frame 2 at this part while rotating the threaded rod 12. At the same time, also rotate multiple tightening bolts 8 on the bottom support ring 7 to timely tighten and fix the lower end surface part of the adjustment sleeve 6 that has separated from the tightening bolts 8 to further ensure the structural stability of the adjustment sleeve 6 after adjustment. This operation continues until the stress at the corresponding part of the pile foundation 1 or the support frame 2 is within a reasonable range to complete the adjustment and ensure the stability of the support of the pile foundation 1 to the support frame 2 at this position.

[0051] Furthermore, an anemometer is arranged at the windward position on the support frame 2 to detect the wind direction and wind speed. The anemometer monitors the wind force changes inside and outside the photovoltaic array area and at each position, studies the attenuation effect of the offshore photovoltaic array on the wind, provides a basis for the selection of the attenuation coefficient in the inner and outer areas of the offshore photovoltaic, and is mutually verified with the conclusions of the wind tunnel test at the same time.

[0052] Referring to the relevant requirements in the "Code for Surface Meteorological Observation" and the "Code for Wind Energy Resource Measurement and Marine Hydrographic Observation in Offshore Wind Farm Projects", the measurement height is based on the average sea level in the wind farm area, and the wind direction and wind speed at a height of 10 m above the sea surface are measured. At the same time, the anemometer is arranged on the windward surface. Here, the stress changes of the pile foundation 1 and the support frame 2 will also be comprehensively considered, and early warnings will be made in a timely manner by detecting the influence of factors such as offshore wind force and wind speed on this operation platform.

[0053] Nine anemometer monitoring points are set in the photovoltaic array, which can be arranged with reference to Figure 6 as shown.

[0054] Furthermore, differential resistance strain gauges are arranged on both the pile foundation 1 and the support frame 2 to detect the stress changes of the pile foundation 1 and the support frame 2 during displacement or deformation. The arrangement of differential resistance strain gauges on the support frame 2 can be referred to the possible maximum deformation position of the support frame 2. Differential resistance strain gauges can be arranged at the pile top, pile body of the pile foundation 1 or at each connecting part of the pile top such as the support adjustment pile position to provide a more accurate deformation position.

[0055] Furthermore, a buffer and anti-collision structure is provided on the pile foundation 1, and the buffer and anti-collision structure includes:

[0056] Side anti-collision plate 13. The side anti-collision plate 13 is composed of two groups of symmetrically arranged plate structures, which are connected at one end to form a V shape. In addition, in order to ensure the structural stability of the V-shaped side anti-collision plate 13, connecting pieces are provided at the end parts of the two groups of plate structures to prevent the two groups of plate structures from being easily separated and damaged. The side anti-collision plate 13 plays a role in preventing sea ice from directly hitting the pile foundation 1, avoiding direct damage to the pile foundation 1 by sea ice;

[0057] Mounting frame 14 is arranged inside the side anti-collision plate 13;

[0058] Connecting frame 15 is a rectangular frame structure, and the connecting frame 15 is connected to the mounting frame 14;

[0059] Guiding support rods 16. There are at least two groups of guiding support rods 16, which are symmetrically arranged in parallel with each other inside the connecting frame 15. A connecting plate 17 is arranged inside the connecting frame 15. Guide holes 18 through which the guiding support rods 16 pass are provided at both ends of the connecting plate 17. A compression spring 19 is sleeved on the guiding support rods 16. The compression spring 19 is compressed between the connecting frame 15 and the connecting plate 17. The connecting plate 17 is rotatably connected to the pile foundation 1 through a bearing, so as to realize that the side anti-collision plate 13 can rotate relative to the pile foundation 1 along the direction of the ocean current.

[0060] Specifically, during actual operation, the side anti-collision plate 13 can follow the ocean current, making the tip of the V-shaped side anti-collision plate 13 face the direction from which the ocean current flows. Therefore, the side anti-collision plate 13 can rotate along the direction of the ocean current. When sea ice drifts along the direction of the ocean current, the tip of the V-shaped side anti-collision plate 13 directly faces the sea ice, reducing the impact loss. At the same time, when the side anti-collision plate 13 is stressed, it drives the connecting frame 15 to move accordingly, and makes the guiding support rods 16 move in the guide holes 18 on the guiding support rods 16, while compressing the compression spring 19 to play a certain buffering role and also play a certain role in protecting the pile foundation 1.

[0061] Furthermore, an ice pressure gauge 20 is arranged between the connecting frame 15 and the mounting frame 14 to directly detect the pressure that the pile foundation 1 will bear through the ice pressure gauge 20 when the side anti-collision plate 13 bears the impact of sea ice, so as to realize detection and early warning, enabling ground staff to make reasonable response plans in a timely manner.

[0062] It should be noted that the above sensors and their use, as well as related data collection and collation work, are all within the scope well-known to those skilled in the art and belong to common general knowledge, so they will not be elaborated further.

[0063] In summary, on the premise that this operation platform detects the stress of the pile foundation and support frame of the offshore photovoltaic through sensors, it can grasp the settlement of the pile foundation and the deformation of the pile foundation and support frame under various factors in real time, such as the settlement of the pile foundation and the deformation caused by sea ice impact. On the premise that this operation platform improves the structural strength of the support frame for supporting the photovoltaic panel through the anti-deformation support structure, it also supports the support frame through the support adjustment pile. When the stress of the support frame changes due to external forces, corresponding structural adjustments are made in a timely manner to ensure the balance of the overall structural stress, so as to solve the platform structural stability brought by external forces. The pile foundation is protected through the buffer anti-collision structure, and the sea ice impact force is detected in real time to make a timely response to ensure timely early warning, ensure the overall stability of the offshore centralized photovoltaic detection and early warning operation platform, and ensure the service life of the operation platform, so that the offshore photovoltaic can develop rapidly and is more conducive to the construction of the energy conservation and environmental protection industry.

[0064] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
