Description

Technical Field

[0001] The present application relates to the technical field of high-voltage transmission line safety detection, and in particular to a device for measuring the displacement of transmission towers caused by ground cracks. Background Art

[0002] Some mining areas, especially shallow coal mines, often experience problems such as ground fissures and subsidence in the goaf. Transmission towers and foundation structures passing through or located on the mining areas generally find it difficult to adapt to the surface movement and deformation of the coal mine goaf. Transmission towers usually tilt and overturn, and the tower bases settle unevenly. At the same time, transmission towers are tall structures and are therefore very sensitive to tilt deformation and have higher requirements for uneven foundation settlement. Therefore, how to collect transmission tower spacing displacement information caused by ground fissures is particularly important for providing data support for the maintenance and correction and reinforcement of the entire transmission line.

[0003] Especially compared with the influence of natural conditions such as wind and snow, the goaf first affects the base of the transmission tower. Measuring the base of the tower can better reflect and more accurately determine the displacement of the transmission tower spacing.

[0034] See also Figures 1-6 In an embodiment of the present application, a device for measuring the displacement of transmission towers caused by ground cracks includes:

[0035] The transmission tower 1 is constructed by connecting a single tower top support 11 and four evenly spaced tower foot supports 12 via a lattice. The tower top support 11 supports multiple groups of transmission cables 2, and a distance measuring component 6 is provided near the top of the tower top support 11.

[0036] The base plates 3 are arranged in multiple pieces and fixed to the lower end surfaces of the tower foot brackets 12;

[0037] The fixed foot bolts 4 are arranged in a group of four, one end of which is deeply embedded in the soil and the other end is fixed to the base plate 3. That is, the lower end of a single base plate 3 is connected to four evenly distributed fixed foot bolts 4, and the upper end is connected to a single tower foot bracket 12. The base plates 3 and fixed foot bolts 4 connected in sequence form a group of tower foundations. Specifically, the fixed foot bolts 4 are screw pile foundations, which are mechanically screwed into the soil layer.

[0038] The calibration components 5 are arranged in multiple numbers, and in the tower base, the calibration components 5 are set between two adjacent fixed foot bolts 4, and the distance measuring component 6 is also set on the lower end surface of the base plate 3.

[0039] It should be explained that the spacing between transmission towers 1 is the center straight line spacing. However, because the device is installed somewhere on the tower body, such as at the top of the tower, the measured spacing is the spacing between the tower tops. In the case of a tilted or damaged transmission tower 1, the measurement data error is too large, and the reference value is reduced.

[0040] Therefore, in this application, while the distance between the transmission towers 1 is measured by the distance measuring component 6, the integrity of a single tower base is monitored by the calibration component 5. In addition, the distance measuring component 6 in the tower base and the distance measuring component 6 on the tower top support 11 communicate to measure the distance, thereby determining the integrity of the tower body. At the same time, the calibration component 5 provides data to assist in determining the settlement of the tower base and the inclination of the tower body, and in conjunction with the calibration of the transmission tower 1 spacing measurement value, improves the monitoring accuracy.

[0041] In this embodiment, Figure 3 , the calibration component 5 includes:

[0042] The sleeve 54 is placed horizontally between two adjacent fixed foot bolts 4, and the two ends of the sleeve 54 are respectively a measuring head end and a measuring tail end. The measuring head end of the sleeve 54 is connected to the fixed foot bolt 4 through the adapter plate 1 51, and the measuring tail end of the sleeve 54 is connected to the fixed foot bolt 4 through the adapter plate 2 52;

[0043] The measuring component 53 is arranged between the adapter plate 1 51 and the sleeve 54 .

[0044] As a preferred embodiment, the sleeve tube 54 is clamped with a support plate 1 541 near the first section of the measurement, and is clamped with a support plate 2 542 near the end of the measurement, and a guard plate 55 is fixedly arranged between the support plate 1 541 and the support plate 2 542, and the guard plate 55 is located below the sleeve tube 54.

[0045] It should be explained that, because the tower base is at a lower level, the outer sleeve 54 of the calibration component 5 and the measuring component 53 can better adapt to the harsh external environment and improve durability.

[0046] As a preferred embodiment, the sleeve tube 54 is fixedly connected to the measuring component 53, and an extension tube 521 is fixedly provided on the adapter plate 2 52. The sleeve tube 54 is slidably sleeved on the extension tube 521. Specifically, when the fixed foot bolt 4 in the same tower base is offset and moved, the sleeve tube 54 and the extension tube 521 slide and change.

[0047] As a preferred embodiment, the adapter plate 1 51 and the adapter plate 2 52 are both fixed to the fixed foot bolt 4 by welding, and a hanging ring is provided inside the extension tube 521, one end of the hanging ring is fixed to the adapter plate 2 52, and the other end faces the measuring component 53.

[0048] In this embodiment, Figure 4The measuring component 53 includes a protective shell 531, a connecting tube 532 and an output tube 533. The connecting tube 532 is fixedly arranged on the side of the protective shell 531, and the output tube 533 is fixedly arranged on the upper end of the protective shell 531. The connecting tube 532 and the output tube 533 are both connected to the interior of the protective shell 531.

[0049] In this embodiment, Figure 5 , the measuring component 53 further includes:

[0050] The torque module 534 is fixedly disposed inside the protective shell 531 and is provided with an external connector 535. A cable extends from the torque module 534 through the external connector 535 and is connected to the outside through the output tube 533, specifically for transmitting signals and energy.

[0051] A rotating shaft 536 is rotatably disposed on the torque module 534, and a through hole is formed on the rotating shaft 536;

[0052] The rotating rod 537 is formed by bending an elastic steel rod, one end of which passes through the through hole of the rotating shaft 536 and the other end is attached to the surface of the rotating shaft 536. A ring is bent in the middle of the rotating rod 537;

[0053] The connecting bracket 539 passes through the sleeve tube 54 through the connecting tube 532, and the two ends of the connecting bracket 539 are respectively connected to the ring of the rotating rod 537 and the hanging ring on the second adapter plate 52 through the connecting buckle 538.

[0054] It should be explained that when the fixed foot bolt 4 is offset, the rotating shaft 536 will rotate, and the corresponding torque module 534 will extract the rotation angle information of the rotating shaft 536, and integrate the information of different measuring components 53 to assist in judging the settlement condition. In addition, during the installation process of the connecting bracket 539, the rotating rod 537 is pulled to make the rotating shaft 536 deflect a part of the angle within the rotation range, so that the connecting bracket 539 is tightened by the torque provided by the torque module 534, thereby improving the sensitivity of the rotating shaft 536. Information collection through mechanical devices is more suitable for long-term harsh outdoor environments.

[0055] As a preferred embodiment, when the rotating shaft 536 rotates, the torque module 534 provides and monitors the magnitude of the deflection angle, and the torque module 534 transmits a signal to the outside.

[0056] In this embodiment, Figure 6The distance measuring component 6 includes a pad 61, a fixed block 62 and a measuring module 63. The measuring module 63 is fixedly connected to the fixed block 62. The fixed block 62 is fixedly set on the tower top bracket 11 and the base plate 3 through the pad 61. Specifically, the measuring module 63 has a leveling module for determining the horizontal value, a communication module for transmitting signals, and a photoelectric module for ranging.

[0057] During specific implementation, the torque module 534 is used to extract the rotation angle information of the rotating shaft 536, and the information of different measuring components 53 is combined to assist in judging the settlement condition. In addition, the distance measuring component 6 in the tower base and the distance measuring component 6 on the tower top support 11 communicate to measure the distance, and then determine the integrity of the tower body. The distance measurement is performed by the distance measuring components 6 between the tower bases to determine the degree of inclination of the tower body. In conjunction with the calibration of the distance measurement value of the transmission tower 1, the monitoring accuracy is improved.

[0058] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and application concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
