Description

Technical Field

[0001] This utility model relates to the field of power pole monitoring technology, specifically a device for synchronous monitoring of the settlement of the power pole body and foundation. Background Technology

[0002] Power poles are crucial infrastructure in power transmission networks, and their stability directly affects the safe operation of the power system. During long-term use, factors such as geological changes, soil subsidence, and external loads can cause settlement or tilting of the power poles and their foundations. Failure to monitor and address these issues promptly can lead to serious accidents such as pole collapse and power line interruptions.

[0003] Currently, settlement monitoring of railway power poles and towers mostly relies on manual periodic measurements or single-point monitoring devices, which have the following shortcomings: manual measurement is inefficient and costly, and it is difficult to achieve real-time monitoring; existing monitoring devices mostly monitor the settlement of the pole and tower body or foundation separately, and cannot achieve synchronous monitoring of the two, making it difficult to accurately reflect the overall stability status of the pole and tower. Utility Model Content

[0004] This application provides a device for synchronous monitoring of the settlement of power poles and their foundations, to solve the problem that existing technologies cannot achieve synchronous monitoring of the settlement of power poles and their foundations. The specific solution is as follows:

[0005] A synchronous monitoring device for settlement of power pole body and foundation includes a power pole body and a settlement synchronous monitoring device. The settlement synchronous monitoring device is installed on one side of the power pole body. The settlement synchronous monitoring device includes an equipment box, and a contact rod, a monitoring module and a control module arranged sequentially from top to bottom inside the equipment box.

[0006] The contact rod is vertically arranged, and its top end is installed at the center of the top plate of the equipment box. The contact rod can rotate around the mounting point with the equipment box.

[0007] The monitoring module is provided in several parts, and the monitoring modules are arranged in a ring around the touch rod as the center;

[0008] The control module is installed on the bottom inner wall of the equipment box, and the control module is connected to several monitoring modules respectively.

[0009] Preferably, a connecting assembly is provided between the touch rod and the top plate;

[0010] The connection assembly includes shock absorbers and connectors;

[0011] The shock absorber is located between the connector and the top plate, and the top and bottom ends of the shock absorber are respectively connected to the top plate and the connector;

[0012] The end of the connector facing away from the shock absorber is connected to the contact rod.

[0013] Preferably, the connector is a spherical connector.

[0014] Preferably, the monitoring module is an inductive sensor.

[0015] Preferably, the settlement synchronous monitoring device further includes a display and an alarm, the display being installed on one side of the equipment box;

[0016] The alarm is installed outside the equipment box, and the display and the alarm are electrically connected to the control module.

[0017] Preferably, the outer surface of the equipment enclosure is provided with an anti-corrosion layer;

[0018] The anti-corrosion layer is applied to the outer wall of the equipment enclosure.

[0019] Preferably, the equipment enclosure has lightning protection.

[0020] The beneficial effects of this application are as follows:

[0021] When the power pole or its foundation settles, the pole will tilt. To address this, this application fixes an equipment box outside the pole, with the bottom and top plates perpendicular to the pole. The contact rod is suspended from the bottom of the top plate of the equipment box, ensuring it is initially parallel to the pole. Several monitoring modules are arranged in a ring around the bottom of the contact rod. When the power pole or its foundation settles, the pole will tilt to varying degrees, and the contact rod will rotate around its connection to the equipment box as the pole tilts. This causes a change in the relative position between the bottom of the contact rod and the monitoring modules at different locations. The corresponding monitoring modules can detect this change and transmit the signal to the control module. The control module can then determine the direction and angle of the pole's tilt based on the signal, thus achieving synchronous monitoring of the settlement of the pole and its foundation.

[0022] This application provides a connecting assembly between the contact rod and the top plate of the equipment box. The shock absorber reduces the impact of external vibrations on the contact rod, ensuring its stability and improving monitoring accuracy. The spherical connector allows the contact rod to rotate flexibly, ensuring that the contact rod can produce a corresponding positional change when the tower body tilts slightly, thus improving monitoring sensitivity.

[0023] The monitoring module uses an inductive sensor to determine whether tilting has occurred by detecting the change in magnetic flux between the contact rod and the monitoring module. The tilt direction is determined by the position of the corresponding monitoring module, and the tilt degree is determined based on the change.

[0024] The equipment enclosure is equipped with an anti-corrosion layer and a lightning protection enclosure, which can effectively resist the erosion of the external environment and the damage of lightning strikes, extend the service life of the equipment, and ensure the stable operation of the equipment in harsh environments.

[0063] Example

[0064] Please see Figure 1-5This embodiment provides a synchronous monitoring device for the settlement of the power pole body and foundation, including the power pole body 12 and the synchronous monitoring device 11, which is installed on one side of the power pole body 12.

[0065] The settlement synchronous monitoring device 11 includes an equipment box, which is a closed box consisting of a bottom plate 1, a top plate 3 and four wall plates 7. Inside the equipment box, from top to bottom, there are a touch rod 6, a monitoring module 5 and a control module (i.e., a controller 2), as well as a display 13 and an alarm 19 located outside the equipment box.

[0066] In this embodiment, the contact rod 6 is made of metal and is vertically arranged. The top of the contact rod 6 is installed at the center of the top plate 3 of the equipment box through a connecting component. The contact rod 6 can rotate around the mounting point of the equipment box.

[0067] In this embodiment, the connecting assembly includes a shock absorber 9 (i.e., a shock absorber) and a spherical connector 8 (i.e., a connector). The shock absorber 9 is located between the spherical connector 8 and the top plate 3. The top and bottom ends of the shock absorber 9 are connected to the top plate 3 and the spherical connector 8, respectively. The end of the spherical connector 8 facing away from the shock absorber 9 is connected to the contact rod 6.

[0068] In this embodiment, the monitoring module 5 is equipped with six sensors: a first sensor 14, a second sensor 15, a third sensor 16, a fourth sensor 17, a fifth sensor 18, and a sixth sensor 10. The first sensor 14, the second sensor 15, the third sensor 16, the fourth sensor 17, the fifth sensor 18, and the sixth sensor 10 are arranged in a ring around the touch rod 6. In this embodiment, the first sensor 14, the second sensor 15, the third sensor 16, the fourth sensor 17, the fifth sensor 18, and the sixth sensor 10 are all inductive sensors of the same specification, and they are connected to the control module through connecting lines 4.

[0069] In this embodiment, the control module is installed on the bottom inner wall of the equipment box (i.e., on the bottom plate 1).

[0070] In this embodiment, both the display 13 and the alarm 19 are mounted on one side panel 7 of the equipment box and are electrically connected to the control module via cables.

[0071] In this embodiment, the equipment enclosure is a corrosion-resistant and lightning-proof enclosure.

[0072] This application monitors the settlement of power poles based on their tilt. When the power pole body 12 or foundation settles, causing the pole to tilt, the equipment box installed on the pole tilts along with it. The contact rod 6 remains vertical under gravity but rotates relative to the equipment box and monitoring module 5. The relative position between the contact rod 6 and the monitoring modules 5 at different locations changes, causing a change in the magnetic flux of the induction coil. The monitoring module 5 converts the magnetic flux change signal into an electrical signal and transmits it to the control module. The control module receives the electrical signals from each induction coil and determines the tilt direction and angle of the contact rod 6 based on the changes in the electrical signals, judging the settlement of the power pole body 12 and foundation, and displays the monitoring data in real time on the display 13. When the monitored settlement or tilt of the pole exceeds the safety value, the control module controls the alarm 19 to sound an alarm, reminding personnel to carry out timely maintenance.
