Description

Technical Field

[0001] The invention belongs to the technical field of transmission tower foundations, and in particular belongs to an integrated system for leveling uneven settlement of transmission towers in goaf areas. Background Art

[0002] Most coal mining is done in underground mines. Artificial mining causes huge "cavities" under the surface, which are called "mined-out areas". Mined-out areas will cause surface deformation to form subsidence basins. The central part of the subsidence basin is mainly vertically subsided, supplemented by horizontal and tilted displacements; while the edge of the basin and the outer edge of the fracture stretching zone are mainly tilted and horizontal displacements. As the process of coal mining accelerates, the scope of mined-out will become larger and larger, and the resulting ground deformation in the mining area will become more and more serious. Large-scale subsidence basins and irregular collapse will appear on the surface. Pits and ground fissures will affect the safe operation of ground buildings. With the vigorous development of UHV transmission technology, many high-voltage transmission towers are inevitably built above goafs. When uneven settlement occurs on the ground surface in goafs, some towers will bend and deform due to foundation collapse, causing tower legs and other components, which will inevitably have a great impact on the safety of high-voltage transmission towers and pole tower bases. In order to eliminate the safety hazards of high-voltage transmission lines in designated goafs and ensure the normal transportation of coal, it is often necessary to carry out large-scale reinforcement of the locations of high-voltage transmission towers in goafs.

[0003] At present, one way to reinforce the location of the high-voltage transmission tower in the goaf on a large scale is to add an adjustment platform at the location of the four independent foundation piles of the tower using reinforced concrete at the location of the high-voltage transmission tower, and change the height of the adjustment platform to make the high-voltage transmission tower reach a balanced state. However, this method manually measures whether the high-voltage transmission tower is tilted before the high-voltage transmission tower is settled and leveled. If the high-voltage transmission tower is manually detected to be tilted, a leveling structure is built at the bottom of the high-voltage transmission tower for leveling. Although this method can level the high-voltage transmission tower, a large number of manual inspections are required during the leveling process, which makes the initial inspection time long and the leveling efficiency low. In addition, during the manual inspection process, due to the different inspection positions of the inspectors, the inspection data obtained will also be biased, resulting in a certain tilt of the high-voltage transmission tower after leveling, and the inspectors will need to conduct irregular inspections in the later stage. Summary of the invention

[0004] In order to solve the problem that during the leveling process of high-voltage transmission towers in existing goaf areas, manual detection errors are large, resulting in a certain inclination of the high-voltage transmission towers after leveling and low leveling efficiency, the present invention provides an integrated system for leveling uneven settlement of transmission towers in goaf areas.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention proposes an integrated system for leveling uneven settlement of transmission towers in goaf areas. Through the integrated detection module, the system can collect status signals of transmission towers in real time and accurately, including key parameters such as inclination and settlement, thereby ensuring the pertinence and effectiveness of adjustment measures. The main control module can perform intelligent analysis based on the data provided by the detection module and generate corresponding control signals, thereby realizing real-time monitoring of the status of the transmission tower and achieving accurate and efficient control of the correction device. The intelligent processing of the main control module greatly improves the response speed and adjustment accuracy of the system, and effectively reduces the impact of uneven settlement on the safe operation of the transmission tower. The correction device, as the actuator of the system, can fine-tune the transmission tower according to the control signal of the main control module, thereby avoiding the inconvenience and cost brought by large-scale construction in traditional methods, and can also achieve effective control of the settlement problem without affecting the normal operation of the transmission tower, thereby providing a strong guarantee for the long-term stable operation of the transmission tower.

[0017] Furthermore, the main control module in this system integrates signal acquisition, data processing, signal conversion, state determination, signal generation and storage functions, realizing comprehensive and efficient processing of transmission tower status signals; the data processing unit adopts the filtering function provided by LabVIEW, which effectively removes the noise interference in the status signal and improves the accuracy and reliability of the data; the status determination unit compares the filtered status signal with the preset status threshold (including the inclination angle threshold and the uneven settlement threshold), which can accurately determine whether the transmission tower has uneven settlement problems and generate control signals in time, thus improving the intelligence level of the system, enhancing the response speed and adjustment accuracy of the system, and providing a more solid technical guarantee for the safe and stable operation of the transmission tower.

[0018] Furthermore, a collector is added to the main control module of the system, and is equipped with a signal interface and a time assignment unit, which enhances the function and practicality of the integrated system for uneven settlement and leveling of transmission towers in goaf areas of the present invention. The collector is closely connected to the detection module through the signal interface, ensuring the accurate and efficient transmission of the status signal of the transmission tower. The introduction of the time assignment unit adds a time tag to each status signal, so that the system can trace the specific collection time of each signal and associate the real-time time with the status signal, which also facilitates the system to continuously and comprehensively monitor the status changes of the transmission tower, thereby improving the monitoring accuracy and timeliness of the system.

[0019] Furthermore, the system adds a prediction and warning unit in the main control module. The prediction and warning unit receives the status signal in real time through the warning acquisition subunit, and uses the warning prediction subunit to compare and analyze the historical accident signals in the historical accident storage subunit. It can accurately predict the accidents that may occur in the transmission tower within the preset time in the future, so as to take preventive measures in advance. The flexibility of the time preset subunit allows the user to set the prediction time interval according to actual needs, which enhances the adaptability and practicality of the system. Once a potential accident risk is predicted, the warning unit will immediately output the prediction result to the signal generation unit, triggering the corresponding warning mechanism to ensure the safe operation of the transmission tower.

[0020] Furthermore, the system adds a data display unit, a user management unit, a fault library management unit and a method self-check unit in the main control module. The user management unit ensures the security and controllability of system access and effectively prevents unauthorized access. The fault library management unit provides technicians with an intuitive and comprehensive basis for fault analysis by recording the status signals of the transmission towers and drawing change curves, which helps to promptly discover and deal with potential problems. The data display unit not only supports users to view the status signals and change curves of the transmission towers on demand, but also has the functions of zooming in, zooming out and exporting data, which greatly improves the convenience of data analysis and use. The introduction of the method self-check unit realizes real-time monitoring and fault warning of the detection system itself, ensuring that the system is always in the best working state, further improving the reliability and stability of the system.

[0021] Furthermore, the power conversion module of this system improves the flexibility and reliability of the power supply of the system. The power conversion module realizes the effective conversion and distribution of the input power through the combination of transformer and converter, ensuring that the detection module and the correction device can obtain stable and appropriate power supply. The introduction of the wireless control switch enables users to remotely control the power on and off, which not only improves the convenience of operation, but also helps to quickly cut off the power supply in an emergency to ensure the safety of personnel and equipment. The wireless control switch is connected to the distributor on the transmission tower through wires, realizing seamless connection with the power system of the transmission tower, ensuring the stable operation of the entire system in complex environments.
