Description

Technical Field

[0001] This utility model relates to the field of monitoring and early warning devices, and in particular to a power tower tilt monitoring and early warning device. Background Technology

[0002] With the rapid development of the power industry, the safety of power transmission towers, as a crucial infrastructure for power transmission, is of paramount importance. In actual use, power transmission towers may tilt due to various reasons.

[0003] On the one hand, natural factors cannot be ignored. For example, strong winds can exert continuous lateral forces on power transmission towers, which may cause them to tilt over time. Geological disasters such as earthquakes can also loosen the tower foundations, leading to tilting. In addition, geological disasters such as landslides and mudslides may alter the topography around the towers, compromising their stability.

[0004] On the other hand, human factors can also cause power transmission towers to tilt. Construction work near the towers, such as excavation and blasting, can affect the stability of the tower's foundation. Additionally, illegal climbing and vandalism can damage the tower's structure, leading to tilting.

[0005] Currently, monitoring methods for power tower tilt are relatively limited. Traditional manual inspection methods suffer from low efficiency, poor accuracy, and the inability to monitor in real time. Moreover, by the time the tilt is detected to a certain extent, it may have already seriously affected power transmission and could even lead to safety accidents. Therefore, there is an urgent need for an efficient, accurate, and real-time power tower tilt monitoring and early warning device to ensure the safe and stable operation of power towers and guarantee the reliability of power supply. Utility Model Content

[0006] The main purpose of this invention is to provide a power tower tilt monitoring and early warning device, which can effectively solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A power tower tilt monitoring and early warning device includes an early warning device horizontally installed on the power tower. The early warning device has a fan-shaped movable cavity and two symmetrical arc-shaped swing grooves on both sides of the movable cavity. An electromagnetic induction ring No. 1 and a electromagnetic induction ring No. 2 are respectively installed at both ends of the two swing grooves. A freely swinging bow-shaped angle monitoring component is movably installed in the movable cavity. The two ends of the angle monitoring component extend into the swing grooves and can swing back and forth freely. During the swing, at the maximum angle, it can extend into the electromagnetic induction ring No. 1, thereby being detected and forming a tilt angle early warning signal.

[0009] Preferably, the housing of the warning device is divided into a front shell and a bottom shell, which are fixedly connected together by screws. A pair of mounting bolts are fixedly installed on the back of the bottom shell, and the warning device is fixedly installed on the power tower by the mounting bolts.

[0010] Preferably, the swing groove is connected to the movable cavity, the second electromagnetic induction ring is installed on the inner wall of the swing groove and close to the inner wall of the movable cavity, and the first electromagnetic induction ring is installed on the other end of the inner wall of the swing groove.

[0011] Preferably, the angle monitoring device includes a long, strip-shaped swing rod, the head of which is equipped with a rotating shaft, and is rotatably connected to the center of the movable cavity through the rotating shaft, so that the swing rod can perform free pendulum motion with the rotating shaft as the center.

[0012] Preferably, an arc-shaped plastic rod is fixedly installed at the tail of the swing arm, and the plastic rod is symmetrically installed on the swing arm to maintain its own center of gravity stability. A counterweight ball is also fixedly installed at the end of the swing arm.

[0013] Preferably, a metal ring is fixedly wrapped around the outer surface of the plastic rod on both sides of the swing rod, and when the swing rod is vertical, the position of the metal ring corresponds exactly to the second electromagnetic induction ring.

[0014] Preferably, a metal rod is fixedly installed at each end of the plastic rod, and the metal rod is also arc-shaped and concentric with the plastic rod.

[0015] Preferably, the warning device is also equipped with a communication module and a power supply and control module. The power supply and control module is electrically connected to the first electromagnetic induction ring and the second electromagnetic induction ring and receives the induction signals from the first electromagnetic induction ring and the second electromagnetic induction ring. The communication module is also electrically connected to the power supply and control module and sends out the induction signals received by the power supply and control module.

[0016] Preferably, an indicator light is also installed on the top of the bottom shell. The indicator light is electrically connected to the power supply and control module and is specifically used to display the induction signal of the second electromagnetic induction ring.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention utilizes a mechanical structure to monitor changes in the tilt angle of power transmission towers. The entire early warning device is horizontally mounted on the tower. It employs an internally drooping angle monitoring component that creates an angle with the tower when it tilts. When this angle exceeds a threshold, electromagnetic induction is triggered, generating an early warning signal which is then transmitted via a communication module to a remote terminal. This allows for timely maintenance of the power transmission tower, preventing further tilting. The entire early warning device features a simple structure, easy installation, strong anti-interference capabilities, real-time monitoring, and is convenient for widespread application.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1 As shown, a power tower tilt monitoring and early warning device includes an early warning device 1 horizontally installed on the power tower. The housing of the early warning device 1 is divided into a front shell 2 and a bottom shell 3. The front shell 2 and the bottom shell 3 are fixedly connected together by screws 4. A pair of mounting bolts 5 are fixedly installed on the back of the bottom shell 3. The early warning device 1 is fixedly installed on the power tower by the mounting bolts 5.

[0026] like Figure 2 , Figure 3As shown, the swing groove 11 is connected to the movable cavity 10. The second electromagnetic induction ring 13 is installed on the inner wall of the swing groove 11, close to the inner wall of the movable cavity 10. The first electromagnetic induction ring 12 is installed at the other end of the inner wall of the swing groove 11. The warning device 1 also houses a communication module 7 and a power supply and control module 8. The power supply and control module 8 is electrically connected to the first electromagnetic induction ring 12 and the second electromagnetic induction ring 13 and receives their induction signals. The communication module 7 is also electrically connected to the power supply and control module 8 and transmits the induction signals received by the power supply and control module 8. An indicator light 6 is also installed on the top of the bottom shell 3. The indicator light 6 is electrically connected to the power supply and control module 8 and is specifically used to display the induction signal of the second electromagnetic induction ring 13.

[0027] like Figure 4 As shown, the angle monitoring component 9 includes a long, narrow swing rod 14. A pivot 15 is mounted at the head of the swing rod 14, and the pivot 15 is rotatably connected to the center of the movable cavity 10, allowing the swing rod 14 to perform free pendulum motion around the pivot 15. An arc-shaped plastic rod 16 is fixedly mounted at the tail of the swing rod 14. The plastic rod 16 is symmetrically mounted on the swing rod 14 to maintain its center of gravity stability. A counterweight ball 19 is also fixedly mounted at the end of the swing rod 14. A metal ring 17 is fixedly wrapped around each side of the plastic rod 16, and when the swing rod 14 is vertical, the position of the metal ring 17 corresponds exactly to the second electromagnetic induction ring 13. A metal rod 18 is fixedly mounted at each end of the plastic rod 16. The metal rod 18 is also arc-shaped and concentric with the plastic rod 16, ensuring that it can also swing freely within the swing groove 11.

[0028] In practical applications, during installation, two or four are typically installed on each power transmission tower, mounted on different vertical surfaces, to detect tilt in four directions and their surroundings. First, two elongated mounting holes, matching the mounting bolts 5, are drilled at appropriate locations on the power tower's frame. Then, the mounting bolts 5 are inserted and pre-locked with nuts. Next, the level of the warning device 1 (base shell 3) is adjusted. Since the angle monitoring component 9 inside the warning device 1 is movable, the swing rod 14 remains vertically downward under the weight of the counterweight ball 19. The warning device 1 is then adjusted so that the second electromagnetic induction ring 13 on the inner wall of the swing groove 11 inside the warning device 1 coincides with the metal ring 17 on the plastic rod 16, thus generating an induction signal. Only when both second electromagnetic induction rings 13 on both sides coincide with the metal ring 17 will the power supply and control module 8 receive two induction signals and control the indicator light 6 to illuminate. This indicates that the warning device 1 is now level. Maintaining this position, the nuts on the mounting bolts 5 are tightened to complete the installation of the warning device 1.

[0029] In actual monitoring, when a power tower tilts due to external forces, the warning device 1 installed on the tower naturally tilts as well. However, its internal angle monitoring component 9, being movable, does not tilt but remains vertically downward. This causes the swing rod 14 to shift within the movable cavity 10, causing the plastic rod 16 to swing in the tilting direction's swing groove 11. When the tilt angle is small, the metal rod 18 at the end of the plastic rod 16 cannot swing to the position of the first electromagnetic induction ring 12, thus failing to trigger its signal. At this time, the metal ring 17 has already deviated from the corresponding second electromagnetic induction ring 13, making it unable to sense its signal. Consequently, the communication module 7 sends the corresponding sensing status to the remote control center. If this state persists, it may indicate a small tilt of the power tower, requiring immediate on-site measurement and inspection by qualified personnel. If this state only lasts briefly before returning to normal, it may be due to strong winds or external impact; in this case, only on-duty inspection personnel need to be dispatched to confirm. When the tilt angle exceeds the threshold, the metal rod 18 will swing directly to the first electromagnetic induction ring 12. This indicates that the power tower has tilted severely or has been hit by an impact that could damage the tower structure. At this time, regardless of whether the induction signal of the first electromagnetic induction ring 12 is continuous, when the signal status is sent to the remote control center through the communication module 7, it is necessary to arrange professional personnel to go to the site for measurement and inspection as soon as possible, and prepare an emergency power outage plan for the line until the on-site inspection and maintenance are completed.
