[0020] 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 described in detail below with reference to the accompanying drawings.

[0021] See also Figure 1-6, an offshore concentrated photovoltaic detection and early warning operation platform, comprising a pile foundation 1 and a support frame 2 supported by the pile foundation 1, the pile foundation 1 mentioned here is a steel pile at the sea surface, the support frame 2 is a steel structure frame, photovoltaic panels are laid on the support frame 2, and an anti-deformation support structure is arranged below the support frame 2, and the anti-deformation support structure is used to strengthen the structural stability of the support frame 2 laid over a large area in various marine environments, a support adjustment pile is arranged on the top of the pile foundation 1, and the support adjustment pile is used to support the bottom of the anti-deformation support structure, when the pile foundation 1 settles, the support frame 2 and the anti-deformation support structure are deformed, resulting in a change in the support stress of the support adjustment pile position, the support height is adjusted by the support adjustment pile to restore the support stress of the anti-deformation support structure, and then after the local deformation or stress change of the operation platform, the support adjustment of the support adjustment pile is achieved to restore the support stress within a preset range, thereby ensuring the long-term stability of the structure of the operation platform and prolonging its service life, and further, avoiding 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 concentrated photovoltaic detection and early warning operation platform; The support adjustment pile includes a supporting part and an adjusting part. The adjusting part adjusts the supporting height relative to the axial direction of the supporting part to restore the supporting stress on the anti-deformation support structure. When the supporting stress is balanced, the relative position between the supporting 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.

[0022] Furthermore, the anti-deformation support structure includes a longitudinal frame 3, which is a plurality of groups arranged parallel to each other below the support frame 2. The longitudinal frame 3 provides structural support to the support frame 2 in the extension direction of the longitudinal frame 3 to ensure structural stability. A transverse frame 4 is arranged between each two adjacent groups of longitudinal frames 3, and the transverse frame 4 is arranged obliquely to the longitudinal frame 3, so as to provide structural support to the support frame 2 in the extension direction of the transverse frame 4 through the transverse frame 4 to ensure structural stability. The longitudinal frame 3 and the transverse frame 4 are both supported by pile foundations 1 , so that each main stress-bearing part below the longitudinal frame 3 and the transverse frame 4 is supported by the pile foundations 1 , so as to better provide stable support for the support frame 2 .

[0023] Furthermore, the longitudinal frame 3 is a triangular support frame structure as a whole, and the transverse frame 4 is a triangular truss structure. The stability of the triangular structure is utilized to provide stable support for the support frame 2, thereby reducing the probability of structural deformation of the support frame 2 on its plane.

[0024] Furthermore, the support part includes a support column 5, and a flange connection is formed between the bottom of the support column 5 and the top of the pile foundation 1, so that the support column 5 can provide a margin of the upper support structure in the event of settlement of the pile foundation 1.

[0025] Furthermore, the adjustment part includes an adjustment sleeve 6, which is sleeved on the support column 5 and slides on the support column 5 along the axial direction; The outer side of the adjusting sleeve 6 is fixedly connected to the longitudinal frame 3 and the transverse frame 4 by setting side wing plates; An adjustment mechanism is provided between the adjustment sleeve 6 and the support column 5 to drive the adjustment sleeve 6 to move axially relative to the support column 5 and to locate the position after the movement.

[0026] Specifically, the adjustment sleeve 6 slides axially on the support column 5, so as to utilize the margin of the support structure provided by the support column 5 to compensate for the stress change caused by the settlement of the pile foundation 1, so as to maintain the stress balance of the support frame 2. This adjustment process is driven by the adjustment mechanism, so that the adjustment sleeve 6 moves axially relative to the support column 5 and locates the moved position, and maintains a balanced support state, so as to continue to maintain the stability of the support frame 2.

[0027] Furthermore, the adjustment mechanism includes a bottom support ring 7, which is fixed to the bottom of the support column 5. A plurality of tightening bolts 8 are arranged circumferentially on the bottom support ring 7 to tighten against the bottom surface of the adjustment sleeve 6. The tightening bolts 8 pass through the bottom support ring 7 and are threadedly engaged with the bottom support ring 7. An assembly plate 9 is arranged above the support column 5, and a plurality of connecting ribs 10 are circumferentially arranged between the lower surface of the assembly plate 9 and the outer surface of the upper end of the adjusting sleeve 6. An internal threaded pipe fitting 11 is penetrated through the center position of the assembly plate 9, and a threaded rod 12 which is threadably matched with the internal threaded pipe fitting 11 is arranged inside the internal threaded pipe fitting 11, and the lower end of the threaded rod 12 is pressed tightly against the upper end surface of the support column 5.

[0028] Specifically, when the stress balance adjustment is performed through the adjustment mechanism, the threaded rod 12 is first rotated by a tool, and under the action of the threaded cooperation between the threaded rod 12 and the internal threaded pipe fitting 11, the lower end of the threaded rod 12 is pressed against the upper end surface of the support column 5, and under the support of the assembly plate 9 and the connecting rib plate 10, it is equivalent to the threaded rod 12 pushing the support column 5 axially downward, and the actual moving part is the adjustment sleeve 6, which is connected to the various components of the anti-deformation support structure to achieve the function of lifting the various components of the anti-deformation support structure. This process can be carried out slowly, so that the stress changes of the pile foundation 1 or the support frame 2 at this part are detected while the threaded rod 12 is rotated, and at the same time, the multiple tightening bolts 8 on the bottom support ring 7 are also rotated, so that the lower end surface of the adjustment sleeve 6 that is separated from the tightening bolts 8 is tightened and fixed in time by the multiple tightening bolts 8, so as to further ensure the structural stability of the adjustment sleeve 6 after adjustment. This operation is performed until it is detected that the stress at the corresponding part of the pile foundation 1 or the support frame 2 is within a reasonable range, so as to complete the adjustment and ensure the stability of the support frame 2 supported by the pile foundation 1 at this position.

[0029] 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 offshore photovoltaic arrays on wind, provides a basis for the selection of attenuation coefficients in the inner and outer areas of offshore photovoltaics, and verifies the conclusions of wind tunnel tests.

[0030] Referring to the relevant requirements in the "Specifications for Ground Meteorological Observation" and "Specifications for Wind Energy Resource Measurement and Marine Hydrological Observation of Offshore Wind Farm Projects", the measurement height is based on the average sea level of the wind farm area, and the wind direction and wind speed at a height of 10m above the sea surface are measured. At the same time, the anemometer is arranged on the windward side. Here, the stress changes of pile foundation 1 and support frame 2 will be integrated, and the impact of offshore wind force, wind speed and other factors on this operating platform will be detected, so as to make timely warnings.

[0031] Set up 9 wind meter monitoring points on the photovoltaic array. Figure 6 Arrangement shown.

[0032] Furthermore, differential resistance strain gauges are arranged on the pile foundation 1 and the support frame 2 to detect stress changes of the pile foundation 1 and the support frame 2 during displacement or deformation. The differential resistance strain gauges arranged on the support frame 2 can be arranged with reference to the possible maximum deformation position of the support frame 2. Differential resistance strain gauges can be arranged at the pile top, pile body or various connecting parts of the pile top of the pile foundation 1, such as the support adjustment pile position, to provide a more accurate deformation position.

[0033] Further, a buffer and anti-collision structure is provided on the pile foundation 1, and the buffer and anti-collision structure comprises: The side anti-collision plate 13 is a symmetrically arranged two-group plate structure 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, a connecting piece is provided at the tail end 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 prevents sea ice from directly hitting the pile foundation 1, thereby preventing sea ice from directly damaging the pile foundation 1. A mounting frame 14, the mounting frame 14 is arranged inside the side anti-collision plate 13; A connecting frame 15, which is a rectangular frame structure and is connected to the mounting frame 14; The guide support rods 16 are at least two groups of guide support rods 16 which are symmetrically arranged in parallel with each other on the inner side of the connecting frame 15. A connecting plate 17 is arranged on the inner side of the connecting frame 15. Both ends of the connecting plate 17 are provided with guide holes 18 for the guide support rods 16 to pass through. A compression spring 19 is sleeved on the guide 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, thereby realizing that the side anti-collision plate 13 can rotate relative to the pile foundation 1 along the direction of the ocean current.

[0034] Specifically, in actual operation, the side impact plate 13 can follow the ocean current so that the tip of the V-shaped side impact plate 13 faces the direction of the ocean current, thereby enabling the side impact plate 13 to rotate along the direction of the ocean current. When the sea ice drifts along the direction of the ocean current, the tip of the V-shaped side impact plate 13 directly faces the sea ice to reduce the impact loss. At the same time, under the force applied to the side impact plate 13, the connecting frame 15 is driven to move accordingly, and the guide support rod 16 is moved in the guide hole 18 on the guide support rod 16, while the compression spring 19 is compressed to play a certain buffering role, and also to play a certain protective role for the pile foundation 1.

[0035] Furthermore, an ice pressure gauge 20 is provided 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 is subjected to the impact of sea ice, thereby realizing detection and early warning, so that ground staff can make reasonable response plans in time.

[0036] 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 known to technical personnel in this field and belong to common knowledge, and will not be elaborated on.

[0037] To summarize, this operation platform uses sensors to detect stress on the pile foundations and support frames of offshore photovoltaics, and can grasp the pile foundation settlement, deformation of the pile foundation and support frame caused by various factors, such as pile foundation settlement and sea ice impact in real time. This operation platform uses an anti-deformation bracket structure to improve the structural strength of the support frame supporting the photovoltaic panels, and also supports the support frame through support adjustment piles. When the support frame is subjected to stress changes caused by external forces, corresponding structural adjustments are made in time to ensure the balance of the overall structural stress, so as to solve the structural stability of the platform caused by external forces, protect the pile foundation through a buffer and anti-collision structure, detect the sea ice impact force in real time, and respond in time to ensure timely 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.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
