Description

Technical Field

[0001] This invention belongs to the field of high-voltage power line tower foundation correction technology, specifically relating to a high-voltage power line tower foundation correction device in a mining subsidence area. Background Technology

[0002] my country has abundant coal reserves, and a large number of high-voltage transmission lines need to cross mining areas, resulting in the common situation of coal being buried under high-voltage towers. As typical tall structures, high-voltage transmission towers have small base areas and high heights, making them extremely sensitive to settlement and tilting caused by surface mining. National standards clearly require that the tilt of straight towers must not exceed 3‰ of the tower height. Once the tower base shifts or the tower tilts beyond the allowable range, it will directly cause serious safety accidents such as power outages and tower overturning, threatening the stability of the power system and the safety of people and property. To mitigate the aforementioned risks, traditional solutions mainly include the mandatory retention of protective coal pillars and the overall relocation of power transmission lines. However, the retention of protective coal pillars requires the delineation of retaining zones based on the protection level of the buildings, resulting in the inability to mine large amounts of coal resources and causing serious resource waste. On the other hand, the relocation of power transmission lines not only involves complex line rerouting designs but also faces practical problems such as long construction periods, high economic costs, and difficulties in implementation due to terrain limitations in some areas. Neither of these solutions can meet the dual needs of resource development and power security. Therefore, in-situ protection technology for high-voltage towers in mining areas has become a key research focus in the industry. In particular, correction devices with repeatable adjustment and dynamic tilt adjustment functions have become a key direction for solving the problem of long-term deformation in mining areas. Currently, existing high-voltage power line tower tilt correction technologies mainly employ methods such as jacking, forced landing, and crane lifting to achieve single-stage tilt adjustment operations. For example, some technologies use spiral anchors, steel beams, and hydraulic jacks to jack the tower base, which can achieve a certain degree of tilt correction, but still requires excavation of foundation pits and modification of the foundation structure, resulting in a complex construction process and a large workload. Other technologies use temporary guy wires, live-line straightening, or foundation reinforcement, all of which are primarily one-time operations and cannot adapt to the long-cycle deformation characteristics of the surface in mining areas, which can last for several months during the initial, active, and decay phases. This makes it difficult to achieve dynamic adjustment throughout the entire cycle. In addition, existing technologies generally lack real-time monitoring systems, making it impossible to capture the tilt trend of the tower base in a timely manner, resulting in delayed adjustments. Furthermore, they rely heavily on manual on-site operations, which are not only labor-intensive but also pose safety hazards due to high-altitude operations. Moreover, existing solutions are not economically viable due to the costs involved in large equipment leasing and foundation modification, and are not suitable for the promotion of multi-tower centralized deployment in mining areas. Further analysis reveals that while existing correction technologies have explored local structural reinforcement or single-time tilt adjustment, they are insufficient to meet the actual needs of full-cycle, multi-point dynamic adjustment, and high-frequency monitoring during mining operations. Therefore, there is an urgent need to develop a high-voltage tower foundation correction device that is simple in structure, easy to operate, repeatedly adjustable, and cost-controllable, in order to solve the many shortcomings of existing technologies and ensure the safe and stable operation of high-voltage transmission lines in mining areas. Summary of the Invention

This device enables dynamic and repeated correction of the high-voltage power line tower foundation, adapts to long-term surface deformation in mining areas, requires no large equipment or complex foundation modifications, is easy to construct and has a short construction period, significantly reduces the amount of work and costs, facilitates centralized deployment and promotion of multiple towers, and forms a stable support by filling and solidifying the top support after support.

[0016] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0017] like Figures 1-9 As shown, a high-voltage power line tower foundation correction device in a mining subsidence area includes four correction structures distributed at the four end positions of the bottom of the high-voltage power line tower 1. Each correction structure includes a base plate 3, which is buried below ground level. The base plate 3 is secured to its installation position with concrete or other materials. An installation plate 5 is fixed at the end corner of the bottom of the high-voltage power line tower 1, and a top plate 4 is fixed to the bottom of the installation plate 5. An installation block 6 is fixed to the side of the base plate 3 and the top plate 4 that are close to each other. A first hydraulic cylinder 2 is installed between two installation blocks 6. The stroke rod of the first hydraulic cylinder 2 is vertically upward. The top of the stroke rod and the bottom of the cylinder body of the first hydraulic cylinder 2 are fixed to a fixing block 7 through a connecting structure. A rotating ball 8 is fixed to the side of the two fixing blocks 7 that are far from each other, and the two rotating balls 8 are movably connected to the two installation blocks 6 respectively. (Refer to the attached figure.) Figure 3 An insulator 9 is fixed to the outer side of the cylinder body and the outer side of the stroke rod of the first hydraulic cylinder 2. A folding telescopic tube 10 is fixed between the two insulators 9 and on the outer side of the first hydraulic cylinder 2. The insulators 9 can avoid lightning and other objects, thus ensuring the insulation effect of the first hydraulic cylinder 2. The folding telescopic tube 10 can seal the connection between the stroke rod and the cylinder body of the first hydraulic cylinder 2 to prevent corrosion from rainwater and other objects. The high-voltage tower 1 is equipped with a tilt monitoring component, a central control component, and a remote interaction component. The tilt monitoring component includes a triaxial tilt sensor, which is detachably fixed to the upper part of the tower body or tower leg of the high-voltage tower 1. The triaxial tilt sensor is used to collect the tilt angle data of the high-voltage tower 1 in real time and output an electrical signal. The central control component includes a control motherboard, a data storage unit, and a communication interface. The control motherboard is electrically connected to the data storage unit and the communication interface, and is also electrically connected to the triaxial tilt sensor via a wire or wireless transmission module to receive and analyze tilt angle data. When the tilt angle exceeds a preset safety threshold, an adjustment control command is generated. The central control component can also be electrically connected to the first hydraulic cylinder 2. The remote interaction component includes a 5G communication module and an alarm unit. The 5G communication module and the alarm unit are installed on the high-voltage tower 1. The 5G communication module is electrically connected to the communication interface of the central control component to remotely transmit tilt angle data and adjustment control commands to the terminal device. The alarm unit is electrically connected to the 5G communication module. When the tilt angle exceeds the preset alarm threshold, the alarm unit is triggered by the central control component to emit an audible and visual alarm signal. The 5G communication module can be installed at the top of the high-voltage tower 1 or at the tower body to ensure communication effectiveness, while the alarm unit can be installed at a lower position at the bottom of the tower to remind people around that the high-voltage tower 1 is tilted and to move away as soon as possible. The alarm unit also includes an audible and visual alarm. See attached document Figures 2-3 When the high-voltage tower 1 is tilted due to the collapse, the tilt state and tilt angle are detected by a three-axis tilt sensor. The three-axis tilt sensor transmits the signal to the central control component, which analyzes the signal and transmits it to the staff through the remote interaction component. The staff immediately rushes to the scene to drive one or two of the first hydraulic cylinders 2, or directly drives the first hydraulic cylinder 2 through the central control component. The first hydraulic cylinder 2 is the first hydraulic cylinder 2 at the tilt position of the high-voltage tower 1, while the other three or two first hydraulic cylinders 2 are in a fixed state. At this time, the driven first hydraulic cylinder 2 extends and drives the top plate 4 and the mounting plate 5 to move upward, pushing the high-voltage tower 1 to a horizontal position. Some construction waste or stone slabs are piled up around the high-voltage tower 1 and inserted around the extended first hydraulic cylinder 2. The construction waste and other objects support the weight, while the first hydraulic cylinder 2 is used to push the high-voltage tower 1, thereby reducing the working time of the first hydraulic cylinder 2 and ensuring the service life of the first hydraulic cylinder 2. By rotating the ball 8, the first hydraulic cylinder 2 extends and its angle changes accordingly with that of the high-voltage tower 1, thus preventing the first hydraulic cylinder 2 from jamming during extension. This allows the high-voltage tower 1 to reset and reach a balanced state when it is slightly tilted, thereby ensuring the service life of the high-voltage tower 1. While the high-voltage tower 1 is still operational, it avoids the need to rebuild a new high-voltage tower 1, which could lead to prolonged power outages. Furthermore, the first hydraulic cylinder 2 can also be a jack or other similar component, allowing for manual operation by the user. Locking structures are installed on the top of the base plate 3 and the bottom of the top plate 4, and the two locking structures are respectively assembled on the outside of the two fixing blocks 7. The locking structures lock the position and angle of the fixing blocks 7.

[0018] See attached document Figure 4Each locking structure includes a mounting bracket 12. Two mounting brackets 12 are respectively mounted on the top of the base plate 3 and the bottom of the top plate 4. Multiple second hydraulic cylinders 13 are fixed to the inner wall of the mounting bracket 12. A clamping plate 14 is fixed to the end of the stroke rod of each second hydraulic cylinder 13 facing the fixed block 7. An arc surface 11 is provided on the outer side of the fixed block 7. After the first hydraulic cylinder 2 extends to a certain distance, the high-voltage tower 1 is in a balanced state. By driving the second hydraulic cylinder 13, the output end of the second hydraulic cylinder 13 drives the clamping plate 14 towards the fixed block 7. The fixed block 7 moves in a certain direction, thereby allowing multiple clamping plates 14 to limit the fixed block 7 and prevent the fixed block 7 from changing angle again, thus sharing the weight of the first hydraulic cylinder 2. Multiple first limiting balls 15 are fixed on the side of the clamping plate 14 near the fixed block 7, and second limiting balls 16 corresponding to the first limiting balls 15 are provided on the outside of the fixed block 7. The clamping plate 14 drives the first limiting balls 15 to move towards the fixed block 7, thereby strengthening the limiting effect on the fixed block 7 through its friction.

[0019] See attached document Figures 5-9 Each connection structure includes a fixing plate 17, and the two fixing plates 17 are respectively fixed to the top of the stroke rod of the first hydraulic cylinder 2 and the bottom of the cylinder body. The fixing plate 17 is internally threaded with a threaded rod 18, and the threaded rod 18 fixes the fixing plate 17 and the fixing block 7 together through the threaded connection. When the first hydraulic cylinder 2 is installed on the two fixed blocks 7, the end of the stroke rod of the first hydraulic cylinder 2 and the bottom of the cylinder body can be welded with a fixing plate 17, and then the fixing plate 17 and the fixing block 7 can be connected together by a threaded rod 18, thereby fixing the first hydraulic cylinder 2 and the fixing block 7 together. When the first hydraulic cylinder 2 needs to be disassembled, the threaded rod 18 can be removed, and the first hydraulic cylinder 2 can be replaced.

[0020] A rotating column 20 is fixed to the bottom of the threaded rod 18, and an end 19 is fixed to the bottom of the rotating column 20. An installation chamber 21 is provided at the bottom of the fixing plate 17, and the rotating column 20 is located inside the installation chamber 21. A magnetic abutment piece 22 is slidably connected to the inner wall of the installation chamber 21, and a snap-fit ​​structure is installed between the magnetic abutment piece 22 and the installation chamber 21. One side of the first snap-fit ​​block 25 and the other side of the second snap-fit ​​block 27 are respectively fixed with a through surface 29 and an abutment surface 30, so that when the through surface 29 of the second snap-fit ​​block 27 rotates to contact the through surface 29 on the first snap-fit ​​block 25, the second snap-fit ​​block 27 can retract into the installation groove 26, and the abutment surface 30 of the second snap-fit ​​block 27 contacts the abutment surface 30 of the first snap-fit ​​block 25, so that the second snap-fit ​​block 27 will not rotate and will be stuck.

[0021] See attached document Figure 8 and attached Figure 9The snap-fit ​​structure includes a first snap-fit ​​block 25 fitted to the inner wall of the magnetic abutment piece 22. Multiple mounting grooves 26 are provided inside the rotating column 20 near its edge. A second snap-fit ​​block 27 is slidably connected within each mounting groove 26. A second spring 28 is installed within each mounting groove 26, and the end of the second spring 28 is connected to the second snap-fit ​​block 27. When the threaded rod 18 rotates, it drives the rotating column 20 to rotate, which in turn drives the second snap-fit ​​block 27 to rotate. When the through surface 29 on the second snap-fit ​​block 27 rotates to contact the through surface 29 on the first snap-fit ​​block 25... Guided by the surface 29, the second locking block 27 slides into the mounting groove 26 and compresses the second spring 28, thereby allowing the rotating column 20 and the threaded rod 18 to continue rotating. When the rotating column 20 wants to reverse due to vibration or other reasons, the abutting surface 30 of the second locking block 27 contacts the abutting surface 30 on the first locking block 25, thereby preventing the second locking block 27 from rotating, and thus preventing the threaded rod 18 and the rotating column 20 from continuing to rotate, thereby ensuring that the first hydraulic cylinder 2 can be stably installed between the two fixed blocks 7. The installation chamber 21 is also equipped with a control structure, which is used to control the position of the magnet abutment piece 22. In this way, when the first hydraulic cylinder 2 needs to be removed, the position of the magnet abutment piece 22 can be controlled to avoid restricting the rotation of the rotating column 20.

[0022] See attached document Figure 7 The control structure includes multiple first springs 23 mounted on the top of the inner side of the mounting chamber 21, with the ends of the first springs 23 connected downward to the magnetic abutment piece 22. Multiple electromagnets 24 are also mounted on the top of the inner side of the mounting chamber 21. Under normal conditions, the magnetic abutment piece 22 is kept in a position where it is engaged with the rotating column 20 by the setting of the first springs 23. When the rotating column 20 needs to be reversed, the electromagnets 24 can be driven to attract the magnetic abutment piece 22, thereby causing the magnetic abutment piece 22 to move upward, so that the first locking block 25 and the second locking block 27 are no longer engaged with each other, and the rotating column 20 can be rotated to reverse.

[0023] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
