[0032] Furthermore, the accompanying drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities.

[0033] The flowcharts shown in the accompanying drawings are merely illustrative and do not necessarily include all steps. For example, some steps may be broken down, while others may be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances. Furthermore, all terms such as "first," "second," etc., used below are for distinction purposes only and should not be construed as limiting the scope of this disclosure.

[0034] The various steps in the method for determining the time to reach the scour pit limit depth of the offshore photovoltaic pipe pile are executed by electronic equipment. This disclosure does not limit the type of electronic equipment, such as a server, personal computer, mobile device, etc.

[0035] Figure 1 A flowchart illustrating a method for determining the time to reach the scour pit limit depth of offshore photovoltaic pipe piles according to an exemplary embodiment of the present disclosure is shown. Reference Figure 1 The method for determining the time required to reach the limit depth of the scour pit of offshore photovoltaic pipe piles may include the following steps:

[0036] S10. Based on environmental data of the offshore photovoltaic area, the pipe piles in the offshore area are grouped in advance to determine multiple pipe pile groups; wherein each pipe pile group includes at least one experimental pipe pile.

[0037] In an exemplary embodiment of this disclosure, the environmental data for the offshore photovoltaic area may include hydrological data and seabed data. Specifically, the hydrological data may include current velocity data, wave data, tidal data, etc., and the seabed data may include particle size distribution, porosity, roughness, etc. After obtaining the hydrological and seabed data for each pipe pile in advance, the pipe piles can be grouped based on the hydrological and seabed data, that is, pipe piles with the same or similar hydrological and seabed data are grouped into the same group. In each group, one or more pipe piles are selected as experimental pipe piles, which serve as representative samples of this group of pipe piles.

[0038] refer to Figure 2 In an offshore area containing multiple offshore photovoltaic (PV) piles, the distribution of other piles may affect the hydrological data of a particular pile. For example, the pile located at the center of a quincunx-shaped pile group corresponds to a lower wave velocity and can be classified as a Class I pile; similarly, piles located at the edges of the quincunx-shaped pile group can be classified as Class II piles; and other piles without nearby composite piles can be classified as Class III piles.

[0039] According to some embodiments of this disclosure, in addition to hydrological data such as wave data, the subsurface sediment data of the pipe piles also affects the time required to reach the ultimate depth of the scour pit. For example... Figure 3 As shown, in the actual operation process, pipe piles with rock strata can be classified into Class I pipe piles, pipe piles with sandy soil strata can be classified into Class II pipe piles, and pipe piles with silty clay strata can be classified into Class III pipe piles.

[0040] When the substrate is also sandy soil, if there are clusters of piles arranged in a quincunx pattern or other group distributions, the impact of the pile group distribution on hydrological data and substrate data can be comprehensively considered to group the piles accordingly. For example, in... Figure 3 In this context, a Class I grouting pile may include two piles distributed in rock strata; a Class II grouting pile may include five piles distributed in sandy soil within a quincunx-shaped pile group; a Class III grouting pile may include one pile located in a non-central position within a quincunx-shaped pile group and distributed in silty clay; and a Class IV grouting pile may include one pile located in the central position within a quincunx-shaped pile group and distributed in sandy soil.

[0041] It should be noted that in the specific implementation of this disclosure, pipe piles can be divided into multiple gradients based on hydrological data, and also into multiple gradients based on subgrade data, so as to classify pipe piles that are in the same hydrological data gradient and the same soil data gradient into the same type.

[0042] S12. Obtain the depth of multiple scour pits corresponding to each experimental pipe pile and the acquisition time corresponding to each scour pit depth.

[0043] According to some embodiments of this disclosure, a multibeam echo sounder can be used to probe each experimental pipe pile to obtain multiple scour pit depths corresponding to each experimental pipe pile, and the time points for obtaining each scour pit depth are recorded. After obtaining multiple sets of scour pit depths and time points corresponding to each experimental pipe pile, the following can be obtained: Figure 4 .

[0044] like Figure 4 As shown, the depth of the scour pit and the corresponding time point obtained by the multibeam echo sounding system are several points including 41 and 43. Here, t0 represents the time point when the depth of the experimental pipe pile was measured for the first time, t1 represents the time point when it was determined that the experimental pipe pile had reached the limit depth, 41 represents the depth of the scour pit obtained during the initial measurement of the scour pit and the time point of the initial measurement, and 43 represents the depth of the scour pit and the measurement time point represented by the last measurement result after it was determined that the experimental pipe pile had reached the limit depth of the scour pit.

[0045] During the measurement of scour pit depth, if the trend of scour pit depth change has slowed significantly, and the difference between two scour pit depth measurements taken per unit time is less than a threshold difference, then it can be determined that the scour pit has reached its limit depth. For example, if the measured depth change of this scour pit within one month is less than 1 mm, it can be determined that the scour pit has reached its limit depth.

[0046] S14. Obtain the environmental data and current scour pit depth of the target pipe pile, and determine the target pipe pile group from multiple pipe pile groups based on the environmental data of the target pipe pile.

[0047] According to an exemplary embodiment of this disclosure, after determining the target pipe pile, environmental data of the target pipe pile is acquired using equipment such as a current meter, tide meter, and shallow seismic profiler. The acquired environmental data is used to match a corresponding experimental pipe pile among various experimental pipe piles as a reference pipe pile. When matching the corresponding experimental pipe pile, it should be ensured that the reference pipe pile has reached its ultimate scour depth. The method for determining whether the scour pit of the experimental pipe pile has reached its ultimate depth can be the method described above, and therefore will not be elaborated further.

[0048] After obtaining the environmental data of the target pipe pile, the current scour pit depth of the target pipe pile can also be obtained through a multibeam echo sounding system, and the time point corresponding to obtaining the current scour pit depth can be recorded.

[0049] S16. When the target pipe pile group includes reference pipe piles, the time when the target pipe pile reaches the limit depth of the scour pit is determined based on the depth of multiple scour pits corresponding to the reference pipe piles and the acquisition time corresponding to each scour pit depth; wherein, the reference pipe pile is the experimental pipe pile whose corresponding scour pit has reached the limit depth.

[0050] According to an exemplary embodiment of this disclosure, in determining the multiple scour pit depths corresponding to the ultimate scour pit depth of the reference pipe pile and the acquisition time corresponding to each scour pit depth, the corresponding acquisition time is obtained, and this acquisition time is the equivalent acquisition time.

[0051] like Figure 4 As shown, if any pipe pile is considered to have undergone a complete scouring cycle from the start of scouring until it reaches its ultimate scouring depth, then the equivalent data acquisition time t is determined. n The progress of the target pipe pile in this type of pipe pile cycle can be determined by the time point 45 corresponding to the reference pipe pile at this scour depth.

[0052] After obtaining the equivalent acquisition time, the acquisition time corresponding to the scour pit limit depth of the reference pipe pile can be subtracted from the equivalent acquisition time to determine the time when the target pipe pile reaches the scour pit limit depth.

[0053] It should be noted that during the implementation of this disclosure, there may be situations where the current scour depth of the target pipe pile and the data acquisition time point exceed the range covered by the sample provided by the reference pipe pile. In this case, the depths of multiple scour pits corresponding to the obtained reference pipe pile and the acquisition time corresponding to each scour pit depth can be fitted to obtain the curve of the scour depth of the experimental pipe pile changing over time.

[0054] like Figure 5 As shown, if the current scour depth of the target pipe pile does not match multiple scour depths of the reference pipe pile, or t n If the time point 55 corresponding to the reference pipe pile at the scour depth is less than t0, that is, if the data of the reference pipe pile is not included in the sample capacity, the number of samples can be supplemented by fitting the depths of multiple scour pits corresponding to the reference pipe pile and the collection time corresponding to each scour pit depth, so as to process the target pipe pile in the entire scour cycle.

[0055] It should be noted that although the steps of the method in this disclosure are described in a specific order in the accompanying drawings, this does not require or imply that the steps must be performed in that specific order, or that all the steps shown must be performed to achieve the desired result. Additional or alternative steps may be omitted, multiple steps may be combined into one step, and / or a step may be broken down into multiple steps.

[0056] Furthermore, this example embodiment also provides a device for determining the time required to reach the scour pit limit depth of offshore photovoltaic pipe piles.

[0062] According to an exemplary embodiment of this disclosure, the second data processing module 67 can be used to determine the time for achieving the scour pit limit depth of the target pipe pile based on the multiple scour pit depths corresponding to the reference pipe pile and the acquisition time corresponding to each scour pit depth. The method further includes: if the target pipe pile group includes one reference pipe pile, determining the time for achieving the scour pit limit depth of the target pipe pile based on the multiple scour pit depths corresponding to the reference pipe pile and the acquisition time corresponding to each scour pit depth; if the target pipe pile group includes multiple reference pipe piles, determining the multiple scour pit limit depth achievement times of the target pipe pile based on the multiple scour pit depths corresponding to each reference pipe pile and the acquisition time corresponding to each scour pit depth; and taking the average or median of the multiple scour pit limit depth achievement times as the time for achieving the scour pit limit depth of the target pipe pile.

[0063] According to an exemplary embodiment of this disclosure, the second data processing module 65 can be used to implement a method for determining the time of reaching the limit depth of the scour pit of offshore photovoltaic pipe piles, and further includes: fitting multiple scour pit depths corresponding to the experimental pipe pile and the acquisition time corresponding to each scour pit depth to determine the change curve of the scour depth of the experimental pipe pile over time; after determining the reference pipe pile among the experimental pipe piles, if the multiple scour pit depths corresponding to the reference pipe pile do not include the current scour pit depth of the target pipe pile, determining the time point corresponding to the current scour pit depth of the target pipe pile according to the change curve.
