Description

Technical Field

[0001] This invention relates to the field of surface deformation-resistant devices and intelligent power equipment in mining areas, and more specifically, to a deformation monitoring system and method for power transmission towers in mining areas. Background Technology

[0002] Surface mining deformation is a common mining-related damage phenomenon, especially in areas with shallow mining depths and thick layers, where the damage is particularly severe. Mining areas are widely distributed in my country, and high-voltage power lines frequently pass through them. Mining deformation often causes tensile and compressive damage to power lines or buried pipelines. Currently, a large number of high-voltage power towers in my country are located in coal mining subsidence areas. Surface deformation can damage power transmission lines. To ensure the safety of residential electricity use and meet the safe supply of electricity needed for social development, regular safety inspections and maintenance of power lines are necessary.

[0003] Protective measures for transmission lines mainly involve reinforcement or designing anti-deformation measures, and regular maintenance. However, this method requires a large number of personnel for maintenance, which is time-consuming and labor-intensive, especially when there are many transmission towers or significant terrain variations. In recent years, methods using finite element method (FEM) prediction in design or reinforcement of older towers have also been explored, such as patents CN201610990249.0 and CN201210278125.1. However, these methods require optimization of the tower structure at the initial construction stage, need to be designed specifically for geological conditions, and lack automatic adjustment devices for grid operation. Another design approach involves monitoring using sensors, as illustrated in patent CN201410624271.4. However, regardless of the current methods—finite element method prediction in design, reinforcement of older towers, or monitoring using sensors—it is difficult to simultaneously meet the needs of monitoring, regulation, systematic management, and display. Summary of the Invention

[0009] In one possible implementation of the first aspect, the leveling assembly further includes two level detection sensors disposed on adjacent sidewalls of the concrete support body.

[0010] In one possible implementation of the first aspect, the adjusting and leveling assembly further includes a plastic threaded protective sleeve disposed above a plurality of connection holes in the concrete support frame to prevent the pre-embedded threaded steel from rusting during surface deformation.

[0011] In one possible implementation of the first aspect, an information transmission module is also included.

[0012] In one possible implementation of the first aspect, the control board is also used to calculate the distance between adjacent transmission towers based on the reflected laser signal.

Detailed Implementation

[0031] The invention will now be further described with reference to the accompanying drawings.

[0032] The deformation monitoring system for power transmission towers in mining areas provided in this application can detect the tilting and settlement of power transmission towers caused by ground deformation through laser ranging and reflectivity technology, and adjust the attitude of the towers through an adjustment mechanism, and then reinforce the adjusted power transmission towers with pre-embedded steel bars.

[0033] Specifically, the deformation monitoring system includes a laser monitoring component 100, a control mainboard 200, and a deformation adjustment mechanism. The laser monitoring component 100 is mounted on the top of the power transmission tower 400 (e.g., [missing information]). Figure 1 As shown, the deformation adjustment mechanism is located at the bottom of the transmission tower 400 to adjust the tower's posture from below.

[0034] like Figure 1 As shown, the laser monitoring component 100 includes a laser transceiver 110 and a laser reflector 120. The laser transceiver 110 can emit laser light and receive reflected laser light. In practice, the laser monitoring components 100 of two adjacent power transmission towers in a mining area are generally arranged at the same height and opposite each other, so that the laser transceiver 110 of one power transmission tower can emit incident laser light onto the laser reflector 120 of the adjacent power transmission tower and receive the laser light reflected from the laser reflector 120. Here, to ensure the reception of reflected laser light, in a single laser monitoring component 100, the laser transceiver 110 should be mounted on the corresponding laser reflector 120, such as... Figure 1 As shown.

[0035] Figure 2A schematic diagram of the laser reflector 120 is shown. It is machined from a single piece of steel and has multiple reflective areas 121 formed on its surface. These reflective areas 121 are distributed vertically and have different reflectivities. Each area is processed using a coating process with significantly different reflectivities. The reflectivity of the laser reflection signal received by the laser transceiver 110 determines which reflective area it originates from, and compares this with the reflectivity at the designed height to determine the relative settlement. It should be understood that the "relative settlement" here refers to the difference between the current height and the designed height of the laser monitoring component.

[0036] Specifically, the control motherboard 200 of this application is used to receive reflected laser signals from the laser transceiver 110, extract the corresponding reflectivity information, compare it with the reflectivity at a preset design height, and obtain the relative settlement amount. For example, three reflection zones 121 with different reflectivities are distributed vertically on the laser reflector 120, such as... Figure 2 As shown; in the initial state, the laser monitoring components 100 of two adjacent transmission towers are set at the same height and relative to each other, that is, the laser transceiver 110 of one transmission tower 400 is directly facing the central reflection area 121 (region 2) of the laser reflector 120 of the other transmission tower, and the initial reflectivity is pre-stored in the control main board 200. When one of the transmission towers 400 settles due to ground deformation, the relative positions of the laser monitoring components 100 of the two transmission towers change, and they are no longer directly facing each other. The laser emitted by the laser transceiver 110 of the transmission tower is reflected in region 3 below region 2. The reflected laser signal is received by the laser transceiver 110 and sent to the control main board 200. The control main board 200 then extracts the corresponding reflectivity information from the received reflected laser signal, determines that the incident laser is reflected by the reflection area 121---region 3 of the laser reflector 120, and determines the amount of settlement of the transmission tower 400 relative to the design height, that is, the relative settlement. Finally, the control motherboard 200 can control the deformation adjustment mechanism to adjust the height of the transmission tower 400 according to the relative settlement amount until the reflectivity in the acquired reflected laser signal is the same as the pre-stored initial reflectivity.

[0037] The following will combine Figure 3 and Figure 4 This application provides a detailed description of the deformation adjustment mechanism provided. The deformation adjustment mechanism may include:

[0038] Transmission tower base assembly 310, which is used to support transmission tower 400; and

[0039] The leveling and adjusting component 320 is located between the transmission tower base component 310 and the transmission tower 400, and can adjust the attitude of the transmission tower 400 under the actuation of the control main board 200.

[0040] Figure 3 This is a structural schematic diagram of the transmission tower base assembly 310. The transmission tower base assembly 310 specifically includes a tower base foundation 311; a pre-embedded steel structure 312, which is releasably installed inside the tower base foundation 311; and multiple mounting foundations 313, each mounting foundation 313 being integrally installed on the top surface of the tower base foundation 311 and having a pre-embedded threaded steel bar 314 fixedly installed on its top surface.

[0041] It should be understood that, in order to ensure stable support for the upper transmission tower 400, the plurality of mounting bases 313 should be evenly distributed on the top surface of the tower base foundation 311. Here, for the purposes of description, Figure 3 The general will use four installation foundations 313 as an example to introduce the technology, which corresponds to the four legs of a traditional power transmission tower 400.

[0042] The tower base foundation 311 has a trapezoidal platform structure, which is integrally cast in concrete and buried in the soil after casting. Its purpose is to increase the weight of the transmission tower foundation and ensure the stability of the power facilities. The installation foundation 313 is the foundation connecting to the superstructure. It is a concrete structure cast together with the tower base foundation 311. Each installation foundation 313 has a pre-embedded threaded steel bar 314 cast on its upper part, and the position and size of the pre-embedded threaded steel bar 314 are consistent with the connection point of the adjusting and leveling assembly 320 (described in detail later). The pre-embedded threaded steel bar 314 is a threaded steel bar to support the overall weight and connect with the supporting adjusting nut plate 322 in the adjusting and leveling assembly 320. Figure 3 The structure is designed to achieve leveling and adjustment. The embedded steel structure 312 is located inside the tower base foundation 311. It includes multiple embedded steel bars that can be releasably installed inside the tower base foundation 311. The installation foundation 313 is equipped with a steel structure interface. After the surface deformation is completed, the steel reinforcement components are welded and concrete is poured to ensure the final stability and strength of the structure.

[0043] Figure 4 This is an exploded view of the structure of the leveling assembly 320. (See attached diagram.) Figure 4 and Figure 3 As shown, the adjusting and leveling assembly 320 may include:

[0044] The concrete support body 321 is set on the transmission tower base assembly 310 and has a "well" shaped outline. Multiple connecting through holes 315 are opened at the four intersections to accommodate the pre-embedded threaded steel bars 314 on the installation foundation 313. The position and size of the connecting through holes 315 are consistent with the corresponding pre-embedded threaded steel bars 314.

[0045] Multiple support adjusting nut plates 322, each fixedly installed on the bottom surface of the corresponding intersection point of the concrete support body 321, including an adjusting nut 3221 threadedly engaged with a pre-embedded threaded steel bar 314, the size and position of which are consistent with those of the pre-embedded threaded steel bar 314; and

[0046] The transmission adjustment mechanism 323 is installed on the concrete support body 321 and includes a bidirectional motor 3231 and a transmission adjustment line 3232. The transmission adjustment line 3232 is connected to the bidirectional motor 3231 and is wound on the groove on the outer surface of the adjusting nut 3221, so that the adjusting nut 3221 can rotate under the drive of the bidirectional motor 3231, thereby rising or falling on the pre-embedded threaded steel bar 314 in the vertical direction.

[0047] In one embodiment, the control board 200 and the bidirectional motor 3231 can be mounted on the side of the concrete support body and enclosed with a thin steel plate.

[0048] Optionally, the adjusting and leveling assembly 320 may also include a plastic threaded protective sleeve 324, which is installed above the four sets of mounting and connecting through holes 315 of the concrete support body 321 to prevent the four sets of pre-embedded threaded steel bars 314 from rusting and to ensure the flexibility of the mechanical structure during adjustment. Furthermore, this invention utilizes electrical energy for power supply, directly drawing power from the transformer on the power line.

[0049] In a preferred embodiment, at least one limiting rod 316 (typically with a diameter smaller than the pre-embedded threaded steel bar 314) is fixedly provided on each mounting base 313 around the pre-embedded threaded steel bar 314. Figure 3 (As shown in four examples), at each intersection of the concrete support body 321, at least one limiting rod through hole 317 is correspondingly provided around the connecting through hole 315. Multiple sleeves 3222 are correspondingly provided on the support adjusting nut plate 322 around the adjusting nut 3221. In this way, each pre-embedded threaded steel bar 314 is accommodated within the connecting through hole 315 along the axial direction of the connecting through hole 315, avoiding the internal stress generated by point contact between the two from creating resistance to the subsequent movement of the adjusting nut 3221 on the pre-embedded threaded steel bar 314.

[0050] In another embodiment, two horizontal detection sensors 325 can be provided on the adjacent sidewalls of the concrete support body 321. These sensors are used to detect the tilt value of the concrete support body 321 relative to the horizontal plane and transmit the tilt value to the control main board 200. The control main board 200 adjusts the bidirectional motor 3231 in conjunction with the transmission adjustment line 3232 to adjust the four sets of support adjustment nut plates 322 respectively, ensuring that the concrete support body 321 is completely horizontal and ensuring the safety of the power transmission tower.

[0051] In another embodiment, the control motherboard 200 can also calculate the distance between adjacent transmission towers 400 based on the reflected laser signal from the laser transceiver 110 of the laser monitoring component 100, and issue an early warning when the power line exceeds the tensile deformation threshold. The principle for measuring the distance change ΔD is as follows: The distance between two adjacent transmission towers is measured according to the formula D = 1 / 2ct (where c is the speed of light and t is the echo time), and the distance is calculated based on ΔD = D... i -D0 (D0 is the initial distance between the transmitting and reflecting components of the device, D i The distance between the transmitting and reflecting components (recorded in the i-th measurement) is calculated, and the measurement result D is compared with the design distance to obtain the change in the spacing between adjacent power towers. The control mainboard 200 then actuates the bidirectional motor 3231 of the transmission tower 400 according to this distance change to control the height / vertical inclination of the concrete support body 321.

[0052] In the above embodiments, such as Figure 5 As shown, the system may also include an information transmission module 500, which is installed in the upper middle part of the transmission tower 400 to facilitate monitoring of data transmission and to protect the relative safety of the data transmission module.

[0053] The following will describe in detail how to install the system provided in this application.

[0054] Based on the transmission line design plan, the installation location of the 400mm transmission tower was determined, followed by foundation pit excavation. The excavation depth and tower base dimensions were determined according to the design and local geological and soil conditions. Then, based on... Figure 3 The transmission tower base assembly 310 is poured, and the installation foundation 313 is poured on top of the tower base foundation 311. The pre-embedded steel structure 312 is arranged around the installation foundation 313. Four sets of pre-embedded threaded steel bars 314 are pre-embedded on the installation foundation 313 according to certain dimensions to ensure that their size and position are consistent with the support adjustment nut plate 322.

[0055] After the transmission tower base assembly 310 solidifies, the processing and installation of the leveling and adjusting assembly 320 will commence. The concrete support body 321 will be poured as required. The concrete support body 321 is designed in a "well" shape, and at the four intersection points of the concrete support body 321 (e.g., ... Figure 4As shown, four sets of connection through holes 315 are reserved, their positions and dimensions being consistent with four sets of pre-embedded threaded steel bars 314. Support adjusting nut plates 322 are installed below the four sets of connection through holes 315, and plastic threaded protective sleeves 324 are installed above the four sets of connection through holes 315. Two horizontal detection sensors 325 are optionally installed on the mutually perpendicular sides of the concrete support body 321. A control main board 200 and a bidirectional motor 3231 are installed on the side of the concrete support body 321 and enclosed with a thin steel plate. The power supply for this system is laid from the power line using a transformer, connecting the control main board 200, bidirectional motor 3231, information transmission module 500, and laser transceiver 110 together.

[0056] The installation of transmission towers can be carried out using traditional methods. And at the top of the transmission tower (e.g., Figure 1 Install laser monitoring component 100. Information transmission module 500 is installed in the middle of the transmission tower (e.g., Figure 5 It also provides multiple interfaces to facilitate the deployment of other monitoring methods and equipment.

[0057] The installation of a single intelligent transmission tower deformation monitoring and adjustment system is now complete. Other transmission towers will be installed in the same manner. After the construction of each unit is completed, the data from each unit will be collected and visualized, including measurement distances, adjustment logs, and monitoring data. Certain thresholds will be set for early warning monitoring, etc.

[0058] After the surface deformation is completed, the transmission adjustment mechanism 323 and plastic threaded protective sleeve 324 in the adjustment and leveling component 320 can be removed, and a new steel structure can be laid using the pre-embedded steel structure 312, and concrete can be poured to complete the final reinforcement work of the transmission tower.

[0060] S610, the laser transceiver 110 of the transmission tower 400 emits laser to the laser reflector 120 of the adjacent transmission tower and receives the reflected laser;

[0061] S620, the control motherboard 200 determines the relative settlement of the transmission tower 400 based on the reflected laser signal from the laser transceiver 110; and

[0062] S630, the control main board 200 actuates the deformation adjustment mechanism of the transmission tower 400 according to the relative settlement, so as to complete the deformation adjustment of the transmission tower 400;

[0063] S640, Remove the adjusting and leveling component 320 and the plastic threaded protective sleeve 324; Utilize the pre-embedded steel structure 312 to lay a new steel structure on the transmission tower 400, and pour concrete to complete the reinforcement work of the transmission tower 400.

[0064] The monitoring process described above, along with accompanying diagrams, has already been described in detail and will not be repeated here.
