Description

Technical Field

[0001] The present invention belongs to the technical field of pole and tower stability, and more specifically, relates to a method for monitoring the state of transmission line poles and towers and timely stabilizing them. Background Art

[0002] With the acceleration of the social industrialization and urbanization processes, the demand for electricity has increased sharply. In some regions, the capacity of the power system can no longer meet the local demand, so cross-river power transmission projects have become an effective solution. However, when crossing river waters, the pole foundations of transmission lines inevitably stand in the riverfront area, and the stability of the pole foundations in the riverfront area of transmission towers is often affected by hydrological factors. Moreover, in some mountainous areas, due to the weak bearing capacity and certain fluidity of the soil itself, settlement and inclination of the pole foundations will inevitably occur at this time.

[0003] Existing technologies mostly stabilize the position of poles and towers by strengthening the compaction effect of the formation and adding diagonal braces, etc. However, as the service time extends, accidents such as inclination of poles and towers still occur. For the above reasons, multiple sensors are installed on the poles and towers in the existing technology to monitor the poles and towers, but it takes a certain amount of time from the sensor to feedback data to the maintenance personnel for maintenance. Therefore, some faults are somewhat concealed, so the stability and service life of the poles and towers still cannot be well guaranteed. Summary of the Invention

[0004] The purpose of the present invention is to provide a method for monitoring the state of transmission line poles and towers and timely stabilizing them, aiming to solve the problems that the poles and towers cannot be effectively supported and there is a lag in dealing with problems when accidents occur.

[0021] Determine the pressure condition of the formation in the length direction of the anchor rod, and infer the change of the formation and the change of the ultimate bearing capacity of the formation through the pressure condition.

[0022] In a possible implementation, inferring the change in the pressure of the pole tower on the anchor rod based on the external force includes:

[0023] Combining the changes in the stresses at different positions of the anchor rod to determine whether the pole tower has a dislocation with the formation under the current external conditions;

[0024] Predict the subsequent external environment. If it is speculated that the external force exceeds the threshold, prepare the filling material in advance.

[0025] In a possible implementation, filling the filling material into a plurality of air bags arranged at intervals on the anchor rod through the anchor rod includes:

[0030] According to the change in the bearing capacity of the formation fed back by the anchor rod, carry out tamping and reinforcement treatment before the bearing capacity of the formation decreases.

Brief Description of the Drawings

[0033] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following will briefly introduce the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings.

[0034] Figure 1 It is a flowchart of the method for monitoring the state and timely stabilizing of transmission line towers provided by the embodiments of the present invention. Detailed Embodiments

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] Please refer to Figure 1 , and now the method for monitoring the state and timely stabilizing of transmission line towers provided by the present invention will be described. The method for monitoring the state and timely stabilizing of transmission line towers includes:

[0037] During the construction of the tower, a plurality of anchor rods are connected to the tower and positioned in the supporting formation, and the change of the formation supporting capacity is detected in real time through the sensors on the anchor rods.

[0038] The shape of the line supported by the tower is determined in real time, and the force exerted by the line on the tower and the force exerted by the external environment on the tower are integrated to determine the total external force received by the tower.

[0039] According to the external force, the change of the pressure of the tower on the anchor rod is inferred. If the change exceeds the preset standard, filling materials are injected into a plurality of air bags arranged at intervals on the anchor rod through the anchor rod, and the sliding resistance between the anchor rod and the formation is increased by the expansion of the volumes of the plurality of air bags, and finally the fixation of the tower is realized.

[0040] The beneficial effect of the method for monitoring the state and timely stabilizing of transmission line towers provided by the present invention is that: compared with the prior art, in the method for monitoring the state and timely stabilizing of transmission line towers of the present invention, during the construction of the tower, a plurality of anchor rods are connected to the tower and positioned in the supporting formation, and the change of the formation supporting capacity is detected in real time through the sensors on the anchor rods. In order to determine the total external force received by the tower, it is necessary to determine the shape of the line supported by the tower in real time and integrate the force exerted by the line on the tower and the force exerted by the external environment on the tower.

[0041] Finally, the change in the pressure of the pole tower on the anchor rod is inferred based on the external force. If the change exceeds the preset standard, filler is injected into multiple airbags arranged at intervals on the anchor rod through the anchor rod, and the sliding resistance between the anchor rod and the formation is increased by the expansion of the volumes of the multiple airbags, ultimately achieving the fixation of the pole tower. Through the anchor rod and the airbags, on the one hand, the present application can ensure the stable support of the pole tower, and on the other hand, it can increase the friction force with the formation before the pole tower fails, avoid the dislocation between the anchor rod and the formation, thereby stabilizing the entire pole tower, extending the service life of the pole tower, improving the efficiency of handling accidents such as inclination, and ensuring timeliness.

[0042] A pole tower is a support for overhead transmission lines to support the transmission wires. Pole towers are mostly made of steel or reinforced concrete and are the main support structures of overhead transmission lines. With the development of social economy, the demand for electricity is getting higher and higher, and the demand for pole towers is also increasing day by day. Gradually, a type of transmission line pole tower has been widely used.

[0043] The support foundation of a communication line pole tower needs to be buried deep underground. For pole towers with a higher erection height, concrete needs to be poured in the foundation pit where it is buried to increase the stability of the pole tower. When the pole tower is poured by the concrete pouring method, a steel bar grid is usually buried at the bottom of the foundation pit to increase the reinforcement strength of the pole tower. When the concrete in the foundation pit is poured, it is necessary to vibrate the concrete manually.

[0044] In some embodiments of the method for monitoring the state and timely stabilizing of a transmission line pole tower provided in the present application, determining the shape of the line supported by the pole tower in real time includes:

[0045] Judging and drawing the shape of the line, and calculating the acting force on the pole tower in combination with the physical parameters of the line and the swinging rate.

[0046] Due to the high position of the electric pole tower where the transmission line is carried, in harsh natural environments such as typhoons, sandstorms, and storms, the upper end of the transmission pole tower is prone to large-amplitude shaking. During the large-amplitude shaking process of the transmission pole towers at both ends of the transmission line, it is extremely easy to cause the transmission line to break, and at the same time, it is also easy to cause the transmission pole tower to tilt and deform. Therefore, monitoring the state of the transmission pole tower is beneficial for timely carrying out repairs and making emergency responses in a timely manner to ensure the safe operation of the transmission pole tower.

[0047] The state monitoring of transmission towers in the prior art is achieved by arranging various sensors on the towers for real-time data collection. For the entire power system or a specified area, the number of distributed transmission towers is large, and generally multiple sensors are installed on each transmission tower. The traditional operation of transmission tower state monitoring is to start other sensors for monitoring when a certain state reaches the design value or threshold. For example, when the wind speed value of the transmission tower reaches the design value, vibration sensors, tilt sensors, pressure sensors, etc. can be started to achieve the state monitoring of the transmission tower.

[0048] However, these existing methods can only perform state monitoring and cannot give earlier warnings, nor can they take timely measures for the abnormal states of the towers.

[0049] In some embodiments of the transmission line tower state monitoring and timely stabilization method provided in the present application, integrating the force exerted by the line on the tower and the force exerted by the external environment on the tower to determine the total external force received by the tower includes:

[0050] Create a model of the tower, analyze and determine the magnitude and direction of the force exerted by the line on the tower at the current time point.

[0051] With the development of processing technology and the progress of digital information, in the current tower construction, by inferring past weather data and referring to physical information such as the weight of the supported line, a tower design scheme with sufficient lifespan and meeting the usage requirements can be designed.

[0052] Tower tilting and collapse mostly occur in extreme weather. For the above reasons, the main faults of current towers are the settlement and tilting of the underlying support foundation, which lead to tower tilting or even deformation. Although the foundation is compacted and reinforced during construction, with the flow of soil in the stratum and the loss of moisture, etc., the supporting force under the tower becomes insufficient, thus causing the deviation of the tower position.

[0053] The present application aims to provide a method for improving the support stability of towers, and more importantly, to avoid tower tilting and monitor the state of the towers at the same time.

[0054] In some embodiments of the transmission line tower state monitoring and timely stabilization method provided in the present application, integrating the force exerted by the line on the tower and the force exerted by the external environment on the tower to determine the total external force received by the tower includes:

[0055] Detect the external weather conditions of the tower to clarify the total force exerted by the external weather on the tower.

[0056] Integrate the forces exerted by the line and the external weather on the tower to determine the external force.

[0057] It should be noted that the main reasons for the problems of the pole tower can be divided into external factors and internal factors. The external factors mainly include the acting force of the line, the influence of the external weather, and the foundation support condition, while the internal factor is mainly the structural strength of the components of the pole tower itself. No matter which kind of fault, it will ultimately cause a change in the acting force of the pole tower on the underlying foundation.

[0058] Taking an embodiment as an example, if the line sways under the influence of the external wind, the acting force of the line sway will act on the pole tower, then the stress at the bottom of the pole tower will change accordingly. At this time, the stress on one side of the pole tower under the action of the line increases significantly, while the stress on the other side decreases significantly. Then it can be determined that the pole tower has a tendency to tilt, and even its own situation has changed.

[0059] By analyzing the change of the stress at the bottom of the pole tower and combining with the remote monitoring of the pole tower, the ultimate goal is to be able to monitor the actual state inside the pole tower and effectively predict before the pole tower undergoes large deformation.

[0060] In some embodiments of the method for monitoring and timely stabilizing the state of the transmission line pole tower provided in the present application, after integrating the acting force of the line on the pole tower and the force of the external environment on the pole tower to determine the total external force received by the pole tower, the following steps are further included:

[0061] Apply the external force to the model to determine the theoretical change degree of the internal stress on the model; analyze whether the components of the model will deform and whether the model will tilt under the action of the external force.

[0062] The purpose of the present application is to improve the support capacity and stability of the pole tower, avoid the change of the position of the pole tower due to insufficient support force. Another purpose is to monitor the state of the pole tower in real time, provide intuitive and accurate data for the unmanned remote monitoring of the pole tower. The last purpose is to increase the support force of the pole tower when an abnormal situation occurs to delay or even stop the tilt of the pole tower to a certain extent.

[0063] To achieve the above technical effects, during construction, after tamping the foundation, drill positioning holes, and then insert anchor rods into the positioning holes. More importantly, an airbag is sleeved outside the anchor rod. The airbag has a certain volume and a closed cavity is formed between the inner side surface of the airbag and the anchor rod. An adjustment hole communicating with the cavity is opened at the center of the anchor rod.

[0064] In actual application, through the adjustment hole in the anchor rod, filling material is introduced into the cavity. Under the action of the filling material, the airbag expands and thus squeezes the soil layer on the wall of the positioning hole. At this time, the bearing capacity of the entire anchor rod can be improved, so as to achieve the purpose of stabilizing the entire pole tower.

[0065] In some embodiments of the transmission line tower state monitoring and timely stabilization method provided in the present application, connecting a plurality of anchor rods to the tower and positioning them in the supporting formation includes:

[0066] Fixing the support base at the bottom of the tower on the anchor rods; the support of the tower is realized by a plurality of anchor rods and the connected construction platform.

[0067] Another object of the present application is to provide a method for monitoring the fluidity and supporting capacity in the soil. First, it should be pointed out that the number of airbags on the anchor rod is multiple, and the multiple airbags are evenly distributed on the anchor rod, with gaps between adjacent airbags. When it is necessary to increase the supporting capacity of the tower, the multiple airbags are simultaneously filled with filling materials, and the volume of the airbags becomes larger, so as to increase the contact area and friction with the soil, and finally achieve the purpose of stabilizing the tower.

[0068] More importantly, a plurality of sensors are arranged along the length direction of the anchor rod. The plurality of sensors are used to detect the acting force of the soil on the anchor rod at different depths. Different acting forces correspondingly reflect the fluidity and density of the soil, because if the soil is loose, the acting force on the anchor rod is relatively small. By real-time feedback of the data detected by the multiple sensors on the anchor rod, the state of the formation can be monitored in real time.

[0069] In some embodiments of the transmission line tower state monitoring and timely stabilization method provided in the present application, inferring the change of the pressure of the tower on the anchor rod according to the external force includes:

[0070] Determining the pressure situation of the formation in the length direction of the anchor rod, and inferring the change of the formation and the change of the ultimate bearing capacity of the formation through the pressure situation.

[0071] In the actual application process, first, the tower and the line are remotely monitored by a drone or a remote monitoring device. It should be particularly noted that the monitoring of the tower mainly determines whether the positions of its various components have changed, whether there is slight shaking or dislocation. After determining that the positions of the components in the tower have not changed, then the shape and swing amplitude of the line on the tower are determined in real time. The final result is to construct a model of the line and calculate the direction and magnitude of the acting force of the line on the tower. It should be pointed out that the acting situation of the line on the tower needs to be calculated in real time and measured.

[0072] Then determine the acting situation of the external environment on the tower. In actual application, it is necessary to determine the wind speed and wind direction outside. After creating the model of the tower, the acting situation of the wind on the entire tower can be determined through physical simulation. After the above situation is determined, calculate the pressure of the tower on the foundation at this time, and compare the obtained pressure with the actual situation for subsequent analysis.

[0073] In some embodiments of the transmission line tower state monitoring and timely stabilization method provided in the present application, inferring the change in the pressure of the tower on the anchor rod according to the external force includes:

[0074] Combining the changes in the stresses at different positions of the anchor rod to determine whether the tower is displaced relative to the formation under the current external conditions.

[0075] Predict the subsequent external environment. If it is inferred that the external force exceeds the threshold, prepare the filling material in advance.

[0076] First, through the sensors on the anchor rod, the force exerted by the tower on the formation can be determined in real time, and through the stress-strain sensors inside the anchor rod, the change in the direction of the force exerted by the tower on the anchor rod can be determined. The content determined by the sensors on each anchor rod is fed back to the upper computer, and then the influence of external factors on the tower is determined. The state of the tower model is restored proportionally in the upper computer. By setting corresponding parameters, the structural strength and state of each component of the model are made the same as the actual ones. After determining the above situation, the force exerted by the tower model on the anchor rod model measured is compared with the actually calculated value, and the difference between the two is analyzed. If the difference exceeds the preset standard, then analyze whether there is a problem with the measurement or whether there is an unobserved problem with the state of the tower, etc. At this time, further analysis is required.

[0077] In some embodiments of the transmission line tower state monitoring and timely stabilization method provided in the present application, filling the filling material into a plurality of airbags arranged at intervals on the anchor rod includes:

[0078] The filling material flows into the plurality of airbags through the adjustment holes opened in the middle of the anchor rod.

[0079] The volume of the airbag expands and squeezes the formation to increase the friction force of the anchor rod relative to the formation.

[0080] Another object of the present application is to provide a method for stabilizing a tower. In this method, a plurality of airbags on the anchor rod are required. For a more detailed description, first, through a plurality of sensors on the anchor rod, the stress condition of the soil in the formation can be determined in real time, so as to give an early warning before a series of problems such as settlement occur. More importantly, when the stress of the soil decreases and the supporting ability of the formation decreases, the volume of the airbag can be expanded to achieve the purpose of stabilizing the tower.

[0081] In some embodiments of the transmission line tower state monitoring and timely stabilization method provided in the present application, increasing the sliding resistance between the anchor rod and the formation by the expansion of the volume of a plurality of airbags includes:

[0082] Timely introduce the filling material into the airbag according to the bearing capacity of the formation, so as to achieve stable support for the tower under the condition of changing bearing capacity.

[0083] According to the change of the formation bearing capacity feedback by the anchor rod, tamping and reinforcement treatment is carried out before the formation bearing capacity drops.

[0084] Another purpose is that when it is detected that the formation state has not changed, but at this time, due to the instability of the pole tower's own components or a large change in the external environment, in order to stabilize the pole tower, the volume of the airbag on the corresponding side of the anchor rod can be increased at this time. Therefore, if the pole tower tilts, the stress on one side of the anchor rod will decrease while the stress on the other side will increase. By reducing the volume of the airbag on the side with reduced stress, the movement of the anchor rod relative to the formation can ultimately be avoided, thus stabilizing the entire pole tower.

[0085] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
