Description

Technical Field

[0001] This invention relates to the field of ultra-high voltage power transmission tower technology, specifically to an ultra-high voltage power transmission tower deformation adjustment device and method. Background Technology

[0002] In coal mining subsidence areas, the extraction of underground coal resources causes surface subsidence and deformation, severely impacting surface infrastructure, especially the tower structures of ultra-high-voltage (UHV) transmission lines. As crucial infrastructure for power transmission, the safe and stable operation of UHV towers directly affects the reliability of the power system and the safety of residents' electricity use. However, traditional tower structures often suffer from uneven foundation settlement and tower tilting when facing surface deformation in coal mining subsidence areas. This not only increases maintenance costs but also significantly threatens the safety of transmission lines.

[0003] To address this issue, existing technical solutions mainly include reinforcing tower foundations and regularly inspecting transmission lines. However, these methods have many shortcomings, such as requiring a large amount of manpower for maintenance, being time-consuming and labor-intensive, and being unable to effectively correct the deformation of towers that have already tilted.

In the disengaged position, the driven gear separates from the driving gear. The tilt detection assembly includes a horizontal plate, support springs, and a tilt detector. The horizontal plate is connected to the top surfaces of the four lifting columns via four support springs.

[0007] In some embodiments, the side wall of the rotating column is provided with a plurality of sliders arranged at intervals along its circumference, and the inner wall of the driven gear is provided with a plurality of sliding grooves, the plurality of sliders corresponding one-to-one with the plurality of sliding grooves, and the sliders slidably engaging with the sliding grooves in the vertical direction.

[0008] In some embodiments, the adjustment assembly further includes a support plate and a telescopic rod. The support plate is sleeved on the rotating column and connected to it, and is located below the driven gear. The telescopic rod is disposed on the support plate and connected to the driven gear, and is used to adjust the position of the driven gear.

[0009] In some embodiments, the top end of the rotating column has an external thread, the lifting column has a threaded hole, the inner wall of the threaded hole is provided with an internal thread that mates with the external thread, and the lifting column is provided with an oil inlet hole for adding lubricating oil to the threaded engagement portion between the rotating column and the lifting column.

[0010] In some embodiments, the adjustment assembly further includes an airbag, an inflator, an air tube, and an exhaust valve.

The first end of the airbag in the vertical direction is located in the first groove and abuts against the bottom wall of the first groove. The second end of the airbag in the vertical direction is located in the second groove and abuts against the bottom wall of the second groove. The inflator is connected to the airbag through the air tube, and the exhaust valve is located in the air tube. The inflator is used to inflate the airbag when the lifting column rises relative to the rotating column, and the exhaust valve is used to discharge the gas in the airbag when the lifting column falls relative to the rotating column.

[0014] In some embodiments, the ultra-high voltage tower deformation adjustment device of the present invention further includes a protective shell, which is disposed on the base, and the top of the protective shell has a through hole for the lifting column to pass through, and at least a portion of the control component is disposed inside the protective shell.

[0015] The method for adjusting the deformation of ultra-high voltage power transmission towers according to embodiments of the present invention, wherein the method is applied to the ultra-high voltage power transmission tower deformation adjustment device described in any of the above embodiments, includes: Detect and confirm the tilt angle and tilt direction of the horizontal plate; Confirm the location and lifting height of the lifting column that needs to be raised or lowered; Adjust each of the lifting columns that need to be raised or lowered, and adjust the driven gear to be in the meshing position so that the driving gear drives the driven gear to rotate, thereby realizing the raising or lowering of the lifting column; The lifting column inflates or deflates the airbag while it is rising and falling.

[0023] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] like Figures 1 to 5 As shown, the UHV tower deformation adjustment device 100 of this embodiment includes a base 1, a tower body 2, a control component, a tilt detection component 5, and a controller 6. The tower body 2 includes four rectangularly distributed columns 201. The control component includes a drive component 3 and four adjustment components 4. The drive component 3 includes a motor 301 and a drive gear 302. The motor 301 is located on the base 1 and connected to the drive gear 302 to drive the drive gear 302 to rotate. The four adjustment components 4 are connected one-to-one with the four columns 201. The adjustment components 4 include a rotating column 401, a lifting column 402, and a driven gear 403. The bottom end of the rotating column 401 is rotatably connected to the base 1, and the top end of the rotating column 401 is threadedly connected to the bottom end of the lifting column 402. The top end of the lifting column 402 is connected to the column 201. The driven gear 403 is vertically adjustable and sleeved on the rotating column 401 to adjust its position. The driven gear 403 switches between an engaged position and a disengaged position. In the engaged position, the driven gear 403 meshes with the driving gear 302, so that when the driving gear 302 drives the driven gear 403 to rotate, the lifting column 402 rises and falls relative to the rotating column 401 in the vertical direction. In the disengaged position, the driven gear 403 separates from the driving gear 302. The tilt detection component 5 includes a horizontal plate 501, support springs 502, and a tilt detector 503. The horizontal plate 501 is connected to the top surfaces of the four lifting columns 402 through four support springs 502. The tilt detector 503 is located on the horizontal plate 501 to detect the tilt angle and tilt direction of the horizontal plate 501. The controller 6 is communicatively connected to the tilt detector 503 and the control component. The controller 6 is configured to control the control component to adjust the horizontal plate 501 to a horizontal state according to the detection value of the tilt detector 503.

[0025] In use, the UHV tower deformation adjustment device 100 of this embodiment of the invention uses a tilt detection component 5 to monitor the tilt angle and direction of the tower in real time via a horizontal plate 501, a support spring 502, and a tilt detector 503. When the tower tilts due to ground subsidence, the tilt detector 503 immediately detects this change. The tilt detector 503 transmits the detected tilt data to a controller 6, which analyzes and processes the data. The controller 6 issues a command based on the tilt data to drive the motor 301 and the drive gear 302 in the control component to rotate. The drive gear 302 meshes with the driven gear 403 in the adjustment component 4 corresponding to the column 201, thereby driving the linkage between the rotating column 401 and the lifting column 402. In the meshing position, the driven gear 403 meshes with the drive gear 302, causing the lifting column 402 to rise and fall vertically relative to the rotating column 401, thereby adjusting the height of the column 201 to correct the tilt of the tower.

[0026] The UHV tower deformation adjustment device 100 of this invention can automatically detect and adjust the tower's tilt state, reducing manual intervention and improving adjustment efficiency and accuracy. Real-time monitoring of the tower's tilt state allows for timely detection and handling of problems, ensuring the tower remains within a safe range. The automatic adjustment mechanism reduces structural damage caused by tower tilt, lowering maintenance and repair costs. Timely correction of tower tilt ensures the stability and safety of the transmission line, reducing the risk of power outages due to line faults. The device is flexibly designed to adapt to different types of UHV tower structures and varying regional ground subsidence conditions. Compared to traditional reinforcement and repair methods, this device utilizes resources more efficiently, reducing the consumption of materials and human resources.

[0027] In some embodiments, the side wall of the rotating column 401 is provided with a plurality of sliders 4011 arranged at intervals along its circumference, and the inner wall of the driven gear 403 is provided with a plurality of sliding grooves. The plurality of sliders 4011 correspond one-to-one with the plurality of sliding grooves, and the sliders 4011 are slidably engaged with the sliding grooves in the vertical direction.

[0028] like Figures 3 to 5 As shown, multiple sliders 4011 on the side wall of the rotating column 401 correspond one-to-one with the sliding grooves on the inner wall of the driven gear 403. This arrangement allows the sliders 4011 to slide vertically along the sliding grooves. When adjusting the position of the driven gear 403, the driven gear 403 is engaged or disengaged from the driving gear 302 by sliding vertically guided by the sliders 4011 and the sliding grooves. Simultaneously, when the driven gear 403 is engaged with the driving gear 302, the driving gear 302 drives the driven gear 403 to rotate through the cooperation of the sliders 4011 and the sliding grooves, thereby improving the stability and safety of the entire adjustment device when transmitting power.

[0029] In some embodiments, the adjustment assembly 4 further includes a support plate 404 and a telescopic rod 405. The support plate 404 is sleeved on the rotating column 401 and connected to it and located below the driven gear 403. The telescopic rod 405 is disposed on the support plate 404 and connected to the driven gear 403, and is used to adjust the position of the driven gear 403. The telescopic rod 405 is communicatively connected to the controller 6 to control the driven gear 403 to be in the meshing position or the disengaged position.

[0030] like Figure 3 and Figure 4As shown, the support plate 404 is sleeved on and connected to the rotating column 401, and is located below the driven gear 403, providing additional support for the telescopic rod 405. The telescopic rod 405 is mounted on the support plate 404 and connected to the driven gear 403. The main function of the telescopic rod 405 is to adjust the position of the driven gear 403. It can adjust the position of the driven gear 403 according to the instructions of the controller 6, switching it between an engaged position and a disengaged position. This allows the driven gear 403 to more precisely engage or disengage with the driving gear 302, ensuring that the driven gear 403 engages or disengages with the driving gear 302, thereby driving the lifting column 402 to move up and down.

[0031] The telescopic rod 405 makes the position adjustment of the driven gear 403 more flexible, allowing it to quickly and accurately switch to different positions as needed to meet the requirements of adjusting different tilt angles. The communication connection between the telescopic rod 405 and the controller 6 enables intelligent control of the entire adjustment process, further reducing the frequency and difficulty of manual intervention.

[0032] In some embodiments, the top end of the rotating column 401 has an external thread, the lifting column 402 has a threaded hole, the inner wall of the threaded hole is provided with an internal thread that mates with the external thread, and the lifting column 402 is provided with an oil inlet hole 4022, which is used to add lubricating oil to the threaded mating part between the rotating column 401 and the lifting column 402.

[0033] like Figure 3 and Figure 5 As shown, the external thread at the top of the rotating column 401 engages with the internal thread on the inner wall of the threaded hole of the lifting column 402, forming a helical transmission mechanism. When the driven gear 403 drives the rotating column 401 to rotate via the slider 4011 and the sliding groove mechanism, the engagement between the external thread on the rotating column 401 and the internal thread on the lifting column 402 allows the lifting column 402 to move up and down along the axis of the rotating column 401. The helical transmission has self-locking properties; after the motor 301 stops driving, the lifting column 402 will not move on its own due to gravity or external forces, thus ensuring the stability of the tower structure.

[0034] Through the threaded engagement, the adjusting device achieves more precise vertical movement, ensuring that the tower structure reaches the expected height during adjustment. Due to the self-locking characteristic of the screw drive, the lifting column 402 will not shift due to external factors after adjustment stops, increasing the stability and safety of the entire device. Compared to other transmission methods, such as gear drives, screw drives reduce energy loss and improve transmission efficiency under the same conditions. The threaded engagement simplifies the structure of the adjusting device, reduces the number of parts, and helps lower manufacturing costs and maintenance difficulty. The smoothness and self-locking nature of the screw drive allow the adjusting device to better adapt to various complex geological conditions, maintaining structural stability even under conditions of significant settlement.

[0035] The oil inlet 4022 is located on the lifting column 402 and is used to add lubricating oil to the threaded connection between the rotating column 401 and the lifting column 402. Lubricating oil enters the threaded connection through the oil inlet 4022, reducing friction between the threads. Regularly adding lubricating oil through the oil inlet 4022 maintains the lubrication of the threaded connection, reducing heat and wear caused by friction. This extends the service life of the threaded connection and reduces maintenance costs.

[0036] In some embodiments, the adjusting assembly 4 further includes an airbag 406, an inflator 409, an air tube 410, and an exhaust valve 411. The top surface of the rotating column 401 is provided with a first groove 4012, and the bottom wall of the threaded hole is provided with a second groove 4021. The first end of the airbag 406 in the vertical direction is located in the first groove 4012 and abuts against the bottom wall of the first groove 4012. The second end of the airbag 406 in the vertical direction is located in the second groove 4021 and abuts against the bottom wall of the second groove 4021. The inflator 409 is connected to the airbag 406 through the air tube 410. The exhaust valve 411 is provided in the air tube 410. The inflator 409 is used to inflate the airbag 406 when the lifting column 402 rises relative to the rotating column 401. The exhaust valve 411 is used to discharge the gas in the airbag 406 when the lifting column 402 falls relative to the rotating column 401.

[0037] The airbag 406 has its two ends located in the first groove at the top of the rotating column 401 and the second groove on the bottom wall of the threaded hole of the lifting column 402, respectively. By adjusting the internal air pressure, the airbag 406 can provide additional support force, which, combined with the threaded support force, improves the stability of the lifting column 402. When the tower structure needs adjustment, the length and support force of the airbag 406 can be changed by inflating or deflating it.

[0038] Airbag 406 provides an alternative support method to threaded supports, allowing the adjustment device to respond more flexibly to different situations and needs. Airbag 406 can absorb and buffer impacts and vibrations caused by external factors (such as wind loads, earthquakes, etc.), protecting the tower structure from damage. The additional support provided by airbag 406 can offer safety assurance in extreme situations; for example, when encountering external forces exceeding the capacity of threaded supports, airbag 406 can provide necessary support to prevent tower damage. Figure 3As shown, the inflator 409 is connected to the airbag 406 via an air tube 410 for inflating the airbag 406. An exhaust valve 411 is located on the air tube 410 for expelling gas from the airbag 406. The combined use of these two devices automatically controls the air pressure within the airbag 406 to accommodate the movement of the lifting column 402 relative to the rotating column 401. When the lifting column 402 moves upward relative to the rotating column 401, the inflator 409 operates, inflating the airbag 406 and increasing its length and supporting force. Conversely, when the lifting column 402 moves downward relative to the rotating column 401, the exhaust valve 411 operates, expelling gas from the airbag 406 and reducing its length and supporting force.

[0039] The inflation device 409 and the exhaust valve 411 automate the air pressure regulation process of the airbag 406, eliminating the need for manual intervention and improving the efficiency and response speed of the adjustment device. The inflation device 409 and the exhaust valve 411 can precisely control the air pressure inside the airbag 406, thereby enabling precise adjustment of the length and support force of the airbag 406 and ensuring the stability of the tower structure.

[0040] In some embodiments, the inflator 409 and the deflation valve 411 are communicatively connected to the controller 6. For example... Figure 3 As shown, the inflator 409 and the exhaust valve 411 are connected to the controller 6 via a communication line, enabling the controller 6 to receive real-time status information from the inflator 409 and the exhaust valve 411 and send control commands to them. When the tilt detection component 5 detects a tilt in the tower, the tilt detector 503 sends the tilt data to the controller 6. The controller 6 determines whether the tower needs adjustment based on a preset algorithm and parameters, and determines the direction and magnitude of the adjustment. The controller 6 sends an inflation command to the inflator 409 or an exhaust command to the exhaust valve 411 to control the expansion or contraction of the airbag 406, thereby driving the lifting column 402 to rise or fall, achieving the adjustment of the tower.

[0041] The communication connection between controller 6 and the air compressor 409 and exhaust valve 411 automates the entire adjustment process, reducing manual intervention and improving efficiency and response speed. Controller 6 can monitor the operating status of air compressor 409 and exhaust valve 411 in real time, adjusting their operating parameters promptly to ensure a smooth and accurate adjustment process. Based on collected data and preset algorithms, controller 6 can intelligently decide whether and how to adjust, improving the system's autonomous decision-making capability. In emergencies, controller 6 can immediately issue stop or reverse adjustment commands to ensure the safety of towers and transmission lines. Because air compressor 409 and exhaust valve 411 are connected to controller 6, system expansion and maintenance become easier, requiring only software updates or hardware replacements. The automated adjustment process significantly reduces the workload of maintenance personnel and improves labor productivity.

[0042] In some embodiments, the adjustment assembly 4 further includes a rotating sleeve 407 and a sealing plate 408. The rotating sleeve 407 extends vertically and is rotatably fitted in the first groove 4012. The sealing plate 408 is disposed at the bottom port of the rotating sleeve 407. The first end of the airbag 406 is located inside the rotating sleeve 407 and abuts against the sealing plate 408.

[0043] like Figure 3 As shown, the rotating sleeve 407 extends vertically and rotatably engages within the first groove 4012. This arrangement protects the airbag 406 from direct friction and wear during the rotation of the rotating column 401, extending the service life of the airbag 406. By reducing wear on the airbag 406, the durability of the entire adjustment device is improved, reducing the frequency of maintenance and replacement.

[0044] In some embodiments, the air tube 410 is provided with a one-way valve 412, which is located between the inflator 409 and the exhaust valve 411, with the outlet of the one-way valve 412 facing the airbag 406. Figure 3 As shown, a one-way valve 412 is located between the inflator 409 and the exhaust valve 411, with its outlet facing the airbag 406. When the inflator 409 is working, the one-way valve 412 ensures that the airflow can only flow to the airbag 406, preventing gas from flowing back into the inflator 409 and ensuring the stability of the air pressure inside the airbag 406.

[0045] In some embodiments of the present invention, the UHV tower deformation adjustment device 100 further includes a protective shell 7, which is mounted on the base 1. The top of the protective shell 7 has a through hole through which the lifting column 402 passes, and at least part of the control component is disposed inside the protective shell 7.

[0046] The protective housing 7 is mounted on the base 1, with a through-hole at the top allowing the lifting column 402 to pass through. Part or all of the control components are housed within the protective housing 7 to protect the mechanical and electronic parts. The protective housing 7 provides physical protection for the control components, preventing damage to internal precision components from external environmental factors such as rain, dust, and extreme temperatures. The protective housing 7 protects the internal components from harsh environmental conditions, improving the adaptability of the device to different climates and geographical conditions. By preventing damage to internal components from external factors, the protective housing 7 helps extend the service life of the control components. The design of the protective housing 7 makes maintenance and repair of the internal components easier, as it can be operated as a single unit. The inclusion of the protective housing 7 reduces interference from external factors on the control components, lowering the risk of failure and thus improving the overall system safety. The presence of the protective housing 7 can, to some extent, prevent unauthorized personnel from misoperating the control components, ensuring stable system operation. For towers located in high-risk areas, such as windy, rainy, or other potentially hazardous areas, the protective housing 7 provides an additional layer of protection, ensuring the stability and reliability of the device.

[0047] The method for adjusting the deformation of ultra-high voltage power transmission towers according to embodiments of the present invention, wherein the method is applied to the ultra-high voltage power transmission tower deformation adjustment device 100 in any of the above embodiments, includes: Detect and confirm the tilt angle and tilt direction of the horizontal plate 501; Confirm the location and lifting height of the lifting column 402 that needs to be raised or lowered; Adjust each of the lifting columns 402 that need to be raised or lowered, and adjust the driven gear 403 to be in the meshing position so that the driving gear 302 drives the driven gear 403 to rotate, thereby realizing the raising and lowering of the lifting column 402; While the rising column 402 is rising and falling, it inflates or deflates the airbag 406. Continue until the leveling plate 501 is in a horizontal position.

[0048] The steps for adjusting the method are as follows: The method for adjusting the deformation of ultra-high voltage transmission towers according to this invention first uses a tilt detection component 5 (such as a tilt detector 503) to detect and confirm the tilt angle and tilt direction of the horizontal plate 501. This is to determine the degree and direction of the tower's tilt so that targeted adjustments can be made.

[0049] Based on the tilt detection results, identify which lifting bollards 402 need to be raised or lowered, and by what height. This is for targeted adjustment of the tower's tilt.

[0050] Adjust each lifting column 402 that needs to be raised or lowered, and put the corresponding driven gear 403 into the meshing position. In this way, when the driving gear 302 rotates, the driven gear 403 can drive the lifting column 402 to rise or fall.

[0051] While the lifting column 402 is being raised and lowered, the airbag 406 is inflated by the inflator 409 or the air in the airbag 406 is discharged by the exhaust valve 411 to adjust the volume and pressure of the airbag 406, thereby helping to achieve precise raising and lowering of the lifting column 402.

[0052] Repeat the above steps until the level plate 501 is adjusted to a horizontal state, that is, the tower is restored to the predetermined vertical position.

[0053] The ultra-high voltage (UHV) transmission tower deformation adjustment method of this invention achieves precise adjustment of the tower's tilt by individually adjusting the inflation / deflation of the lifting column 402 and the airbag 406, ensuring the tower's levelness and stability. The entire adjustment process can be automated, reducing manual intervention and improving efficiency and accuracy. The tilt detection component 5 can monitor the tower's tilt status in real time, enabling rapid response to changes in ground deformation during the adjustment process. Precise adjustment of the tower's tilt reduces the risk of structural damage caused by tilt, improving the safety of the transmission line. Timely adjustment of the tower's tilt reduces stress concentration caused by uneven settlement, extending the service life of the tower and control components. The automated adjustment process reduces the need for manual maintenance, lowering maintenance costs. Ensuring the stable operation of the tower improves the reliability of power supply to the transmission line and reduces the risk of power outages.
