Description

Technical Field

[0001] This disclosure relates to the field of wind turbine blade transportation technology, and in particular to a wind turbine blade transportation and loading method, system, equipment, medium and procedure product. Background Technology

[0002] Wind turbine blades are characterized by their large size, heavy weight, high value, complex aerodynamic shape, and a certain degree of structural flexibility. During the transportation of wind turbine blades, environmental factors (such as road bumps during land transport, ship swaying during sea transport, and the effects of wind and waves) can easily excite vibrations and significant deformations in the blades. These dynamic responses mean that the actual space occupied by the wind turbine blades during transportation may be much larger than their static geometric dimensions.

[0003] In existing technologies, the safe transport of wind turbine blades often relies on manual experience. Based on simple static morphological calculations of the blades, a large safety margin is allowed to determine the actual load-bearing scheme. This method depends on the assembly personnel's historical experience, which, on the one hand, makes it difficult to cover the extreme environmental impacts that wind turbine blades may encounter during transport, easily leading to safety hazards such as blade collision damage in extreme environments; on the other hand, setting an excessively large safety margin can reduce the number of wind turbine blades transported per trip, thus increasing transportation costs.

Detailed Implementation

[0013] Based on the relevant descriptions in the background art, the current transportation and loading of wind turbine blades often relies on manual experience. Based on simple static morphological calculations of the blades, a large safety margin is used to determine the actual loading scheme. This scheme, on the one hand, fails to cover the extreme environmental impacts that wind turbine blades may encounter during transportation, easily leading to safety hazards such as blade collision damage in extreme environments. On the other hand, setting excessively large safety margins can reduce the number of blades transported per trip, thereby increasing transportation costs. To solve the above technical problems, some embodiments of this disclosure provide a wind turbine blade transportation and loading method, system, equipment, medium, and program product, which can effectively improve the safety and efficiency of wind turbine blade transportation and loading.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the various embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details are provided in the embodiments of this disclosure to facilitate a better understanding of the disclosure. However, the technical solutions claimed in this disclosure can be implemented even without these technical details and various variations and modifications based on the following embodiments. The division of the following embodiments is for ease of description and should not constitute any limitation on the specific implementation of this disclosure. The various embodiments can be combined with and referenced by each other without contradiction.

[0015] In some embodiments of this disclosure, Figure 1 A schematic flowchart of a wind turbine blade transportation and loading method is shown, as follows: Figure 1 As shown, process 100 may specifically include the following steps: Step 110: Based on the transportation planning of the wind turbine blades, determine the theoretical environmental data of the wind turbine blades during transportation. It is understood that in practical applications, wind turbine blades have a long, slender, flexible structure, which is easily affected by changes in the transportation environment during transportation, resulting in vibrations. For example, in land transportation scenarios, uneven road surfaces and speed bumps may cause periodic impacts and random vibrations, which are external excitations. These external excitations are transmitted to the wind turbine blades through the transportation space or the fixed supports of the wind turbine blades, causing vibrations. The wind turbine blade transportation and loading method provided in this disclosure simulates and estimates the possible vibrations of the wind turbine blades during transportation, and then makes reasonable adjustments to the loading method based on the simulation estimates. In the above process, it is necessary to prioritize the estimation of the external excitations that the wind turbine blades may experience during transportation. That is, based on the transportation planning of the wind turbine blades, the theoretical environmental data of the transportation route area can be determined. In some embodiments, taking land transportation scenarios as an example, the theoretical environmental data may specifically include weather and road conditions in the transportation route area obtained based on the transportation planning, which are not limited here.

[0016] In some embodiments, taking a maritime transport scenario as an example, when wind turbine blades are transported by sea, the theoretical environmental data of the wind turbine blades during transport includes at least one or any combination of the following: environmental wind direction, the extreme wind speed corresponding to the environmental wind direction, environmental wave direction, and the extreme wave height corresponding to the environmental wave direction. It is understood that in land transport scenarios, large wind turbine blades are often transported individually, or the number of wind turbine blades mounted in the same transport space is relatively small, and collisions and interference between multiple wind turbine blades are less frequent. However, in maritime transport scenarios, multiple wind turbine blades are often mounted in the same transport space, and for economic reasons, it is necessary to utilize the limited transport and loading space as much as possible to transport a larger number of wind turbine blades in a single trip while ensuring the safe transport of wind turbine blades. Therefore, the technical solution provided in this disclosure is particularly suitable for the maritime transport scenario of wind turbine blades. In some embodiments, for maritime transport scenarios, the external excitation experienced by wind turbine blades during transport mainly originates from the wind and waves affecting the transport vessel during maritime transport. Accordingly, the theoretical environmental data of wind turbine blades during transport can mainly include environmental wind direction, wind speed, environmental wave direction, wave height, and other data information of the sea areas through which the wind turbine blades pass. The above data information can be obtained in advance based on the determined maritime transport plan for wind turbine blades, the transport date, and the marine weather forecast of the transport route area, and is not limited here. In some embodiments, further, during maritime transport, the greater the wind speed faced by the transport vessel, the greater the possible vibration amplitude of the wind turbine blades due to external excitation; similarly, the greater the wave height faced by the transport vessel, the greater the possible vibration amplitude of the wind turbine blades due to external excitation. Therefore, in the process of determining the theoretical environmental data, it is necessary to acquire extreme sea state data such as extreme wind speed data and extreme wave height data of the sea areas traversed during maritime transport, so as to provide a data basis for subsequently obtaining the maximum vibration range that the wind turbine blades may generate, effectively ensuring that the dynamic clearance of each wind turbine blade can still meet the safety transport requirements under extreme sea state environments. Users can also choose other suitable environmental prediction data as the above-mentioned theoretical environmental data according to actual needs, without limitation.

[0017] Step 120: Based on theoretical environmental data and the associated transportation simulation model of the wind turbine blades, determine the simulated space occupied by the wind turbine blades during transportation. It is understood that theoretical environmental data and the associated transportation simulation model of the wind turbine blades can simulate the vibration and displacement of the wind turbine blades under the influence of external environmental loads. Based on this vibration and displacement, the simulated space occupied by the wind turbine blades during transportation can be determined. This simulated space can cover the vibration and displacement of the wind turbine blades under possible extreme environmental scenarios and can serve as a reference basis for the subsequent safe transportation and assembly layout of the wind turbine blades. The specific method for determining the simulated space will be explained in detail later and will not be elaborated here.

[0018] Step 130: Based on the simulated occupied space, adjust the assembly layout of each wind turbine blade in the transportation space to ensure that the assembly layout meets the preset transportation conditions. In some embodiments, the simulated occupied space obtained based on the relevant steps of the foregoing embodiments can characterize the maximum vibration range that the wind turbine blades may experience during transportation. The assembly layout of each wind turbine blade in the transportation space can be determined based on the distribution of the simulated occupied space in the transportation space. This assembly layout can meet the preset safe transportation requirements of the wind turbine blades. That is, even if the wind turbine blades face extreme environments during transportation, there will be no risk of collision between each wind turbine blade or between the wind turbine blades and the internal boundaries of the transportation space (e.g., the inner wall of the container), effectively ensuring the transportation safety of the wind turbine blades. This is not limited here. In some embodiments, further, in addition to meeting the safe transportation requirements of the wind turbine blades, the preset transportation conditions also need to maximize the space utilization efficiency of the transportation space. That is, while meeting the safe transportation conditions, the loading layout of the wind turbine blades should be set as compactly as possible so that as many wind turbine blades as possible can be carried in a single transportation process, thereby improving the utilization rate of the transportation space and effectively reducing the transportation cost of the wind turbine blades. The specific adjustment process for the assembly layout will be explained in detail later, and will not be repeated here.

[0019] It is understood that the wind turbine blade transportation and loading method provided by the above process 100 can effectively improve the safety and efficiency of wind turbine blade transportation and loading. The specific implementation of each step in the above process 100 will be further explained and illustrated below with specific embodiments.

[0020] In some embodiments of this disclosure, Figure 2 This paper presents a schematic diagram illustrating the process of determining the simulated space occupied by wind turbine blades during transportation, based on theoretical environmental data and a transportation simulation model associated with wind turbine blades. Figure 2 As shown, process 200 may specifically include the following steps: Step 210: Based on the flexible dynamics model of the wind turbine blade, the transport carrier model of the wind turbine blade, and the support fixture model of the wind turbine blade in the transport carrier, establish a transport simulation model related to the wind turbine blade. In some embodiments, specifically, a high-precision multibody dynamics simulation model can be jointly established based on the flexible dynamics model of the wind turbine blade, the transport carrier (e.g., ship, vehicle, etc.) model of the wind turbine blade tip, and the support fixture model of the wind turbine blade set in the transport space of the transport carrier; this is not limited here.

[0021] Step 220: Based on theoretical environmental data, simulate the vibration of the wind turbine blades during transportation using a transportation simulation model. It is understood that the transportation simulation model can determine the environmental load on the wind turbine blades based on theoretical environmental data, and based on the environmental load and the structural characteristics of the blades, obtain the temporal vibration displacement data of the wind turbine blades during transportation, which serves as the simulated vibration of the wind turbine blades during transportation. The transportation simulation model can determine the simulated vibration based on dynamic simulation (e.g., based on the finite element method, multibody dynamics method, etc.), which is not limited here.

[0022] Step 230: Based on the simulated vibration, determine the simulated space occupied by the wind turbine blades during transportation. It can be understood that through the above process 200, the vibration displacement that the wind turbine blades may generate during transportation can be quantitatively characterized based on the transportation simulation model, and the simulated space occupied by the wind turbine blades during transportation can be formed. The specific method for determining the simulated space will be explained in detail below with reference to specific embodiments.

[0023] In some embodiments of this disclosure, Figure 3 This diagram illustrates a process for determining the simulated space occupied by wind turbine blades during transportation based on simulated vibration conditions. Figure 3 As shown, process 300 may specifically include the following steps: Step 310: Based on the design morphology parameters of the wind turbine blades, multiple vibration reference sections are set in the spanwise direction of the wind turbine blades, and at least one vibration reference point is set on the airfoil profile of the vibration reference sections. In some embodiments, the user can select multiple sections as vibration reference sections in the spanwise direction of the wind turbine blades according to the actual size of the wind turbine blades and transportation needs; preferably, the vibration reference sections can be distributed as evenly as possible in the spanwise direction of the wind turbine blades, so as to better simulate the overall possible vibration of the wind turbine blades, but this is not limited here.

[0024] Step 320: Based on the simulated vibration conditions, determine the trajectory of the vibration reference point during the transport process of the wind turbine blades. For example, Figure 4 A schematic diagram of the displacement of a vibration reference point is shown, such as... Figure 4 As shown, based on the simulation of environmental excitation, the displacement time trajectory 410 of the vibration reference point in the global coordinate system can be obtained, which is not limited here.

[0025] Step 330: Based on the point movement trajectory, determine the two-dimensional motion envelope of the vibration reference section corresponding to the vibration reference point during the transport of the wind turbine blade. It can be understood that, given the point movement trajectory of the vibration reference point, for any point on the airfoil profile of the vibration reference section, the point movement trajectory during the transport of the wind turbine blade can be obtained through coordinate transformation based on the rigid geometric relationship with the vibration reference point, thereby obtaining the two-dimensional motion envelope of the entire vibration reference section during the transport of the wind turbine blade. For example, Figure 5 A schematic diagram of the two-dimensional motion envelope of a vibration reference section during the transport process of a wind turbine blade is shown. In some embodiments, such as Figure 5 As shown, the motion trajectory of the vibration reference section during the wind turbine blade transportation process is as follows: Figure 5 As shown in the shaded area 510, this represents the spatial trajectory swept by all points on the airfoil profile of the vibration reference section during the transport of the wind turbine blade. In some embodiments, such as Figure 5 As shown, the two-dimensional motion of the vibration reference section during wind turbine operation includes, for example: Figure 5 As shown in closed curve 520, it can be understood that the two-dimensional motion envelope of a vibration reference section is the smallest closed boundary that can contain all points on the airfoil profile corresponding to that vibration reference section, such as... Figure 5 The closed curve 520 shown can just encompass the entire shaded area 510, and is not limited here. In some embodiments, for the convenience of subsequent calculations, the two-dimensional motion envelope of the vibration reference section during the transport process of the wind turbine blade is smoothed so that it is slightly larger than the corresponding airfoil motion trajectory. Users can adaptively fine-tune the obtained two-dimensional motion envelope according to actual needs, and is not limited here.

[0026] Step 340: Based on the two-dimensional motion envelopes of all vibration reference sections during the transportation process of the wind turbine blades, determine the three-dimensional motion envelope of the wind turbine blades during transportation, which serves as the simulated space occupied by the wind turbine blades during transportation. In some embodiments, specifically, in 3D modeling software, based on the two-dimensional motion envelopes corresponding to each vibration reference section and the actual spatial positions of the vibration reference sections on the wind turbine blades, these two-dimensional motion envelopes are smoothly connected through a surface construction mode to form a complete 3D entity (surface model). This 3D entity (surface model) is the three-dimensional motion envelope of the wind turbine blades during transportation, which can characterize the maximum dynamic space that the wind turbine blades may occupy during the entire transportation process, i.e., the simulated space occupied by the wind turbine blades during transportation. For example, Figure 6 A schematic diagram simulating the space occupied by a wind turbine blade during transportation is shown. In some embodiments, such as Figure 6 As shown, plane 610 is the two-dimensional motion envelope of each vibration reference section during the transportation process of the wind turbine blade, and three-dimensional solid 620 is the three-dimensional motion envelope formed by the surface fitting of each plane 610. Users can also choose other feasible technical means to determine the three-dimensional motion envelope of the wind turbine blade during the transportation process through the two-dimensional motion envelope of all vibration reference sections according to the actual application scenario, which is not limited here.

[0027] In some embodiments of this disclosure, the simulated space occupied by the wind turbine blades during transportation is further associated with the assembly orientation of the wind turbine blades relative to the transportation space. It is understood that if the wind turbine blades have the same assembly orientation relative to the transportation space during transportation, the environmental loads they experience in the transportation space can be considered the same. The parameters of the transportation simulation models corresponding to these wind turbine blades are identical, and the simulated space occupied by the environmental loads is also the same; that is, wind turbine blades with the same assembly orientation have the same simulated space occupied during transportation. In some embodiments, common assembly layouts during the transportation of wind turbine blades include unidirectional stacking layouts and interlocking stacking layouts: for example, Figure 7 A schematic diagram of the assembly of a wind turbine blade with a unidirectional stacked layout is shown. Figure 8 A schematic diagram of an assembly of wind turbine blades in a plug-in stacked configuration is shown. In some embodiments, as... Figure 7In the unidirectional stacking layout shown, all wind turbine blades 710 are stacked in the same orientation and direction, and their assembly direction relative to the transport space is the same. Therefore, it can be assumed that the response of all wind turbine blades to environmental loads is essentially the same during the same transport process. Only one simulation is needed, and the simulated space occupied by any one wind turbine blade can be used as the simulated space occupied by all other wind turbine blades for subsequent assembly layout adjustments, thus saving on simulation computation. This is not limited here. In some embodiments, as shown... Figure 8 In the interlocking stacked layout shown, the wind turbine blades 810 are stacked along a first direction relative to the transport space, and the wind turbine blades 820 are stacked along a second direction relative to the transport space, with the second direction opposite to the first direction. Since the assembly directions of the wind turbine blades 810 and 820 are different, the parameter composition of the transport simulation models corresponding to the wind turbine blades 810 and 820 is also different, and their responses to environmental loads during the same transport process are also different. Two independent simulation processes are required to obtain the simulated space occupied by the wind turbine blades corresponding to the two assembly directions, which is not limited here.

[0028] In some embodiments of this disclosure, in the specific implementation of step 130 in the aforementioned embodiments, during the process of adjusting the assembly layout of the wind turbine blades in the transportation space based on the simulated occupied space of the wind turbine blades, the preset transportation conditions specifically include that the minimum distance between the simulated occupied spaces of each wind turbine blade is greater than a preset safe loading threshold, and the minimum distance between the simulated occupied space of each wind turbine blade and the boundary of the transportation space is greater than the safe loading threshold. It can be understood that the simulated occupied space of the wind turbine blades can reflect the vibration displacement of the wind turbine blades under environmental excitation during transportation. If the minimum distance between the simulated occupied space of the wind turbine blades and the simulated occupied spaces of other blades, as well as the internal boundary of the transportation space, is greater than the safe loading threshold, it indicates that even under the most unfavorable dynamic response to environmental excitation, no collision will occur between the wind turbine blades and the transportation space. The aforementioned quantified benchmark settings can ensure that the assembly layout of the wind turbine blades meets the safe transportation requirements in the preset transportation conditions.

[0029] In some embodiments of this disclosure, further, in the specific implementation of step 130 in the aforementioned embodiments, during the process of adjusting the assembly layout of the wind turbine blades in the transportation space based on the simulated occupied space of the wind turbine blades, the preset transportation conditions also include that the difference between the minimum spacing between the simulated occupied spaces of each wind turbine blade and the safe loading threshold is less than a first threshold, and the difference between the minimum spacing between the simulated occupied spaces of each wind turbine blade and the boundary of the transportation space and the safe loading threshold is less than a second threshold. It is understandable that setting the difference between the minimum spacing between the simulated occupied space of each wind turbine blade and the safe loading threshold to be less than the first threshold, and setting the difference between the minimum spacing between the simulated occupied space of each wind turbine blade and the boundary of the transportation space and the safe loading threshold to be less than the second threshold, can make the minimum spacing between each wind turbine blade and the inner boundary of the transportation space as close as possible to the safe loading threshold. This can ensure the safe transportation of wind turbine blades while maximizing the utilization rate of the transportation space and the transportation efficiency of wind turbine blades. Based on the relevant descriptions of the aforementioned embodiments, given the simulated occupied space of the wind turbine blades, all possible vibration displacements of the wind turbine blades during transportation are included in the simulated occupied space. There is no need to set excessive or excessive safety margins. The utilization rate of the transportation space can be maximized as much as possible while ensuring that the simulated occupied spaces do not interfere with each other. More wind turbine blades can be loaded in a single transportation process. The assembly layout of the wind turbine blades can meet the transportation space utilization requirements in the preset transportation conditions through the above-mentioned quantitative benchmark settings, thereby improving the transportation efficiency of the wind turbine blades. In some embodiments, further, given a determined upper limit on the number of wind turbine blades to be transported in the transport space, the gap between each wind turbine blade and the inner boundary of the transport space can be further adjusted evenly based on the remaining space allowance to further improve the transport safety of the wind turbine blades; this is not limited here. In some embodiments, the user can freely set the specific values ​​of the first threshold and the second threshold as needed; this is not limited here.
