[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0030] In one embodiment of the present invention, a method for assessing damage to a transmission tower affected by a landslide is provided. Figure 1 Figure 2 is a flow chart of a method for assessing damage to a transmission tower affected by a landslide according to an embodiment of the present invention. The technical solutions of this embodiment of the present invention are applicable to assessing damage to transmission towers located above or below a landslide. This method can be performed by a damage assessment device for transmission towers affected by a landslide, which can be implemented in software and / or hardware.

[0031] like Figure 1 As shown, the damage assessment method for a transmission tower affected by a landslide according to an embodiment of the present invention specifically includes the following steps:

[0032] S110: Construct a simulation model of the transmission tower based on basic parameters of the transmission tower.

[0033] The basic parameters include the tower type parameters and pole parameters of the transmission tower. Transmission tower types include four-support towers and three-support towers. Pole parameters include pole type, pole size, and pole material. Pole components refer to the components that construct the transmission tower, including main and diagonal materials. Optionally, in this embodiment of the present invention, the transmission tower type is the commonly used four-support tower.

[0034] Specifically, a simulation model of the transmission tower can be constructed based on the tower type parameters and pole member parameters of the transmission tower. Alternatively, a finite element model of the transmission tower can be constructed based on the tower type parameters and pole member parameters of the transmission tower. Alternatively, a finite element model of the transmission tower can be constructed using ANSYS software.

[0035] S120: Acquire target load data corresponding to the transmission tower based on the location type of the transmission tower.

[0036] The location types include above and below the landslide. A transmission tower can be located above or below the landslide.

[0037] Specifically, according to the location type of the transmission tower, target load data corresponding to the transmission tower is obtained, so as to prepare for subsequently obtaining the stress distribution of the transmission tower based on the target load data.

[0038] S130: Based on the target load data and the simulation model, obtain the stress distribution on the transmission tower through simulation.

[0039] The stress distribution includes the stress value of at least one member in each transmission tower. Under the target load, the tower members are subjected to varying degrees of stress. Using the target load data and simulation model, the stress distribution of each member of the transmission tower can be simulated, paving the way for subsequent damage assessment results.

[0040] S140. Obtain a damage assessment result of the transmission tower based on the stress distribution.

[0041] In this embodiment of the present invention, a damage assessment result for a transmission tower is obtained through stress distribution calculation. For example, a preset calculation formula can be used to calculate the stress distribution and determine the damage status of the transmission tower's components, thereby obtaining a damage assessment result for the entire transmission tower. This allows personnel to inspect and repair the transmission tower based on the simulated damage assessment results, ensuring timely inspection and maintenance of the transmission tower and preventing damage to the transmission line caused by damage to the tower.

[0042] The technical solution of the embodiments of the present invention constructs a simulation model of a transmission tower based on its basic parameters, obtains target load data corresponding to the tower based on the tower's location type, simulates the stress distribution on the tower based on the target load data and the simulation model, and then obtains a damage assessment result for the tower based on the stress distribution. The technical solution of the embodiments of the present invention achieves damage assessment results for transmission towers affected by landslides, both above and below the landslide, improving the accuracy of the damage assessment results. It also provides data support for personnel during transmission tower maintenance, accelerating the efficiency of tower maintenance.

[0043] Transmission towers installed on or below landslides are more susceptible to environmental influences than those located on flatter terrain. Natural factors such as the texture of the landslide, the level of the groundwater level, the surrounding terrain, and trees can all affect the condition of the transmission towers, thereby impacting high-voltage power transmission. Monitoring the natural environment allows for continuous monitoring of the operating environment and condition of transmission towers. This collected data allows for damage assessments, facilitating on-site inspections and repairs.

[0044] In another embodiment of the present invention, the location types include above and below the landslide, and different location types correspond to different target load data. The stress distribution of the transmission tower is obtained by using the target load data corresponding to different location types and the simulation model, and then the maximum stress value is obtained. Specifically, when the location type of the transmission tower is below the landslide, the target load includes a first target load, and the first target load data includes the volume, velocity, and initial height of the landslide body; the stress distribution of the transmission tower is obtained by simulation based on the target load data and the simulation model, including: based on the first target load data and the simulation model, using a nonlinear dynamic analysis simulation method to calculate the first target load data to obtain a stress distribution cloud map of the transmission tower, and obtaining the maximum stress value from the stress distribution cloud map.

[0045] Specifically, when the transmission tower is located under a landslide, the first target load data includes the volume and velocity of the landslide. Based on the simulation model and the various parameters of the landslide, the stress distribution on the transmission tower is obtained. The various parameters mainly include the volume, velocity, and initial height of the landslide. In the embodiment of the present invention, the nonlinear dynamic analysis simulation method is used to calculate the stress on the transmission tower rods when it collides with the landslide, such as Figure 2As shown. The figure shows the inclination of the transmission tower under the landslide caused by the impact of the landslide body (the oblique line part in the figure) before and after the transmission tower is impacted. The height H of the transmission tower, the height x (impact height) of the highest point where the landslide body impacts the transmission tower, the initial height h of the landslide body, the speed v of the landslide body (not shown in the figure), the volume V of the landslide body, etc. can all be obtained through on-site monitoring instruments. Based on these data and the simulation model, the first target load data is calculated using a nonlinear dynamic analysis simulation method to obtain a stress distribution cloud map of the transmission tower, and the maximum stress value is obtained from the stress distribution cloud map. Optionally, the volume of the landslide body can be estimated by image recognition technology, and the speed of the landslide body can be measured by a sensor, such as a surface monitoring device reading the sliding speed of the landslide body. The height of the transmission tower can be obtained by a photoelectric sensor that measures the height.

[0046] In another embodiment of the present invention, obtaining the damage assessment result of the transmission tower based on the stress distribution includes: obtaining the damage assessment result of the transmission tower based on the maximum stress value.

[0047] In this embodiment of the present invention, a nonlinear dynamic analysis simulation method is used based on a simulation model to calculate the first target load data, thereby obtaining a stress distribution cloud map of the transmission tower under the impact of the landslide. The maximum stress value is then determined from the stress distribution cloud map, and a damage assessment result of the transmission tower is obtained. In this embodiment of the present invention, the damage status of the transmission tower members is determined based on the maximum stress value, which serves as the damage assessment result of the transmission tower.

[0048] Optionally, based on the stress distribution cloud map, the rod corresponding to the maximum stress value is obtained as the maximum stress rod, and the overall inclination rate of the transmission tower is calculated to obtain the relationship curve between the kinetic energy of the landslide body and the maximum stress of the rod, and then the stress-displacement curve is obtained, for example, Figure 3 As shown, the stress-displacement curves of the main material and the diagonal material are shown. Based on the stress-displacement curves, the corresponding stress can be obtained when the displacement of the transmission tower rod is obtained. The damage assessment result of the transmission tower is obtained based on the stress. It should be understood that the rod includes the main material and the diagonal material. In this embodiment of the present invention, the stress-displacement curves of the main material and the diagonal material of the transmission tower are obtained. Then, based on the stress-displacement curves and the displacement of the transmission tower obtained on site, the corresponding damage assessment result of the transmission tower can be obtained, thereby improving the efficiency of obtaining the damage assessment result of the transmission tower.

[0049] In another embodiment of the present invention, obtaining the damage assessment result of the transmission tower based on the stress distribution includes: calculating the difference between the stress distribution and the material yield limit of each pole of the transmission tower, and obtaining the damage assessment result of the transmission tower according to the difference.

[0050] In this embodiment of the present invention, the stress distribution refers to the stress condition of each member of a transmission tower. The difference between the stress on each member of the transmission tower and the material yield strength of each member is calculated, and the damage assessment result of the transmission tower is derived based on the difference. Optionally, the member with the maximum stress is identified based on the stress distribution. The damage assessment result of the transmission tower is then derived based on the difference between the stress of this member and the material yield strength of this member. For example, a relationship between the damage level and the difference is established. When the difference is greater than 1, the member damage level is the highest, and therefore the damage level of the transmission tower is the highest. When the difference is within the range of [0.95, 1), the member damage level is the second highest, and therefore the damage level of the transmission tower is the second highest. When the difference is within the range of [0.75, 0.95), the member damage level is the low, and therefore the damage level of the transmission tower is the low. When the difference is less than 0.75, the member damage level is safe, and therefore the transmission tower is safe. When a transmission tower's damage level reaches the highest level, it indicates a risk of collapse. By obtaining the damage assessment results for the transmission tower, workers can prepare for tower maintenance and improve the stability of normal transmission line operation.

[0051] In another embodiment of the present invention, the damage assessment result includes a risk warning; the damage assessment result of the transmission tower obtained according to the difference includes: obtaining the risk level based on the correspondence between the preset difference and the risk level, and the difference, and performing a risk warning corresponding to the risk level.

[0052] In an embodiment of the present invention, the damage assessment result includes a risk warning. According to the pre-set correspondence between the difference and the risk level, the risk level corresponding to the difference is obtained, and a risk warning corresponding to the risk level is issued. In an embodiment of the present invention, the correspondence between the difference and the risk level, as well as the relationship between the risk level and the risk warning are pre-set. If the difference is in the range of [1,∞), the risk level is the highest level, and the highest level risk warning is sent through a display interface, terminal, etc. If the difference is in the range of [0.95,1), the risk level is the second highest level, and a message of the second highest level risk warning is pushed through the terminal. If the difference is in the range of [0.75,0.95), the risk level is low, and a low-level risk warning is announced through the display interface. When the difference is less than 0.75, there is no risk, and no risk warning is issued.

[0053] For example, to examine whether a rod is damaged, the main purpose is to determine whether the rod reaches the material yield limit under a certain load. Taking Q345 steel as an example, the yield limit of this material is 345 MPa, taking a 95% safety factor and a 75% sub-safety factor, when the difference between the calculated maximum stress of the rod and the material yield limit is in the range of [1, ∞), the risk of rod damage is extremely high, and the highest level warning is issued; when the difference between the calculated maximum stress of the rod and the material yield limit of the rod is in the range of [0.95, 1), the risk of rod damage is relatively high, and a secondary level warning is issued; when the difference between the maximum stress of the rod and the material yield limit of the rod is in the range of [0.75, 0.95), the rod is relatively safe, and a lowest level warning is issued; in addition, when the difference between the maximum stress of the rod and the material yield limit of the rod is less than 0.75, the rod is safe and no warning is issued.

[0054] In another embodiment of the present invention, when the location type of the transmission tower is on a landslide, the target load includes second target load data, the second target load data includes displacement data of the transmission tower, and the displacement data includes at least one of vertical settlement and horizontal movement; the simulation based on the target load data and the simulation model to obtain the stress distribution of the transmission tower includes: judging the foundation deformation condition of the transmission tower according to the second target load data and the simulation model, and simulating the foundation deformation condition to obtain the maximum stress value of the transmission tower, wherein the foundation deformation condition includes any one of uneven settlement, horizontal relative deformation, and three-dimensional deformation.

[0055] In an embodiment of the present invention, the foundation deformation condition of the transmission tower is determined based on the obtained second target load data of the transmission tower and the simulation model. A spatial coordinate system is established based on the actual location of the transmission tower, and then the vertical settlement data and / or horizontal movement data of the transmission tower are obtained. Optionally, the transmission tower is a four-support tower type, and the displacement data of the four supports of the transmission tower can be obtained, and then the foundation deformation condition of the transmission tower is obtained based on the displacement data of each support and the simulation model. According to the foundation deformation condition, the maximum stress value of the rod in the transmission tower is obtained. Then the maximum stress value of the transmission tower is obtained to prepare for the subsequent damage assessment of the transmission tower. The transmission tower on the landslide is as follows. Figure 4 shown.

[0056] Optionally, the four supports of the transmission tower are a, b, c, and d, and the foundation deformation conditions include uneven settlement, horizontal relative deformation, and three-phase deformation. Uneven settlement, for example, occurs when one support settles, and settlement also occurs at supports a, b, c, or d. Settlement on one side of the transmission tower may occur on side ab, side ac, side bc, or side ad.

[0057] Optionally, horizontal relative deformation includes two situations: horizontal compression and horizontal stretching. For example, horizontal compression is the compression of support a in the horizontal direction. According to the spatial rectangular coordinate system and preset rules, it can be judged whether the support has undergone horizontal stretching or compression when the coordinates of the support change. For example, a spatial rectangular coordinate system is established with the center of the four supports as the origin, and the coordinates of support a are (1,0,0). When the coordinates of support a are (0.1,0,0), it can be judged that support a has undergone compression. Similarly, it can be obtained whether other supports have undergone compression or stretching.

[0058] Optionally, the three-dimensional deformation includes two situations: vertical settlement and horizontal compression, and vertical settlement and horizontal stretching. Similarly, the coordinate changes of each support can be obtained by the above-mentioned coordinate determination method to determine whether the three-dimensional deformation has occurred.

[0059] Optionally, for transmission towers located on landslides, the difference between the maximum stress value of the transmission tower and the yield strength of the pole can be used to obtain risk warning information corresponding to the difference, thereby issuing a risk warning. Based on the second target load data and simulation model on the landslide, a settlement-to-pole maximum stress curve is obtained. Based on the first target load data and simulation model below the landslide, a landslide kinetic energy-to-pole maximum stress curve is obtained. The monitored settlement or landslide kinetic energy is then incorporated into the corresponding maximum stress curve for matching and comparison, resulting in the maximum stress of the transmission tower pole, also known as the maximum stress of the transmission tower. The difference between the maximum stress and the yield strength of the pole is then calculated, and a warning is issued based on the result.

[0060] It should be noted that for transmission towers on landslides, the maximum stress value can also be used to obtain damage assessment results for the transmission towers. The principle of obtaining damage assessment results based on the maximum stress value for transmission towers under landslides is the same as the above, and will not be repeated here.

[0061] In another embodiment of the present invention, the basic parameters also include insulator parameters and conductor parameters of the transmission tower; constructing the simulation model of the transmission tower based on the basic parameters of the transmission tower includes: constructing a simulation model of at least two transmission towers connected by conductors; after obtaining the damage assessment result of the transmission tower based on the stress distribution, the method further includes: judging whether the other transmission tower is damaged based on the damage assessment result of the transmission tower and the conductor connecting the transmission tower and the other transmission tower.

[0062] In this embodiment of the present invention, a finite element model is created using ANSYS software to simulate a "three-tower, two-wire" transmission tower. The finite element model is based on the actual tower parameters, pole parameters, insulator string type, and conductor type. After obtaining the damage assessment results for the current transmission tower, the conductors are used to determine whether another connected tower has sustained damage. For example, if the current transmission tower collapses, the connected tower could also collapse due to the conductor connection.
