Description

Technical Field

[0001] This utility model relates to the field of tilt monitoring technology, specifically a device for monitoring the tilt of power transmission towers. Background Technology

[0002] In power transmission and distribution networks, power towers serve as the core support for overhead transmission lines, and their structural stability is a crucial foundation for ensuring the safe operation of the power grid. Due to factors such as geological subsidence, wind loads, and climate change, towers may tilt or even collapse, leading to accidents such as short circuits and power outages, seriously threatening the continuity and reliability of power supply. Therefore, real-time monitoring of power tower tilt, timely detection of structural hazards, and early warning have become key technical requirements for the operation and maintenance of transmission lines.

[0003] Existing power tower tilt monitoring devices generally adopt a multi-sensor combination technology. Although this approach can monitor the tilt of power towers, it suffers from many problems such as high cost, difficulty in calibration, and susceptibility to electromagnetic interference. Moreover, while existing devices can rely on electronic sensors and circuit systems to monitor the tilt of power towers, there is no tilt threshold for power towers, which may lead to incomplete monitoring and excessive tilting of power towers.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example

[0026] Please see Figures 1 to 5 The present invention provides a technical solution for a power tower tilt monitoring device, including a fixed cover 3 and a scale 4. A fixed rod 11 is fixedly connected to the upper inner side of the scale 4, and a rotating rod 6 is connected to the rear outer side of the fixed rod 11 through a bearing. A gravity ball 7 is fixedly connected to the bottom of the rotating rod 6.

[0027] The upper end of the rotating rod 6 is provided with a first electrode block 9, the upper part of the fixed cover 3 is provided with a sliding groove 2, the inner side of the sliding groove 2 is slidably connected with a slider 14, and the lower part of the slider 14 is provided with a second electrode block 10.

[0028] Specifically, the first electrode block 9 and the second electrode block 10 are both made of conductive metal and tin-plated on the surface to enhance conductivity. A damping sleeve is fitted on the outside of the gravity ball 7. The sleeve is filled with silicone oil or air damping medium with a damping coefficient of 0.5-1.0 N·s / m to attenuate the swaying caused by wind and vibration.

[0029] Please refer to Figure 1. Figure 2 and Figure 6 A second connecting rod 13 is fixedly connected to the lower front part of the rotating rod 6. A pointer 12 is fixedly connected to the front end of the second connecting rod 13. The front end of the second connecting rod 13 slides on the inner side of the dial 4.

[0030] Specifically, pointer 12 has a conical structure with a tip width of ≤0.5mm and a distance of 0.2-0.3mm from the scale line 5, ensuring a reading error of ≤0.5°. Both the second connecting rod 13 and pointer 12 are made of stainless steel with a tensile strength of ≥520MPa to prevent deformation over long-term use.

[0031] Please refer to Figure 1 to Figure 2 The front side of the dial 4 is provided with scale lines 5, which cooperate with the pointer 12.

[0032] Specifically, the scale line 5 is based on the center of the circle and is evenly distributed at 1° intervals, with a minimum scale division of 0.5° and a range of ±15°.

[0033] Please refer to Figure 4 to Figure 5 The inner side of the slider 14 is threaded with a threaded pin 1, and the upper outer side of the threaded pin 1 is engaged with the fixed cover 3.

[0034] Please refer to Figure 4. The first electrode block 9 is electrically connected to the external monitoring equipment, and the second electrode block 10 is electrically connected to the external monitoring equipment.

[0035] Specifically, the first electrode block 9 and the second electrode block 10 form a series circuit. When the two come into contact, the circuit is turned on, and the monitoring equipment triggers an audible and visual alarm.

[0036] Please refer to Figure 1 and Figure 3 A first connecting rod 8 is fixedly connected to the bottom of the fixed cover 3, and a dial 4 is fixedly connected to the lower end of the first connecting rod 8.

[0037] Specifically, the first connecting rod 8 is made of aluminum alloy, such as 6061-T6, with an elastic modulus ≥70GPa, to ensure connection rigidity.

[0038] In use, rotate the threaded pin 1 to loosen the threaded connection between the threaded pin 1 and the slider 14, then move the threaded pin 1, which in turn causes the slider 14 to slide inside the groove 2. Then the slider 14 causes the second electrode block 10 to move. According to the actual application, the second electrode block 10 is placed in a suitable position. Then rotate the threaded pin 1 to tighten the threaded connection between the threaded pin 1 and the slider 14. When the power tower tilts, due to the force of gravity, the gravity ball 7 is always downward, which causes the rotating rod 6 to rotate around the fixed rod 11, so that the rotating rod 6 is always in the vertical direction. This causes the second connecting rod 13 to slide inside the scale 4. The second connecting rod 13 causes the pointer 12 to move. The pointer 12 cooperates with the scale line 5 to read the tilt angle of the power tower. At the same time, the rotating rod 6 rotates around the fixed rod 11, causing the first electrode block 9 above the rotating rod 6 to move. When the first electrode block 9 contacts the second electrode block 10, it indicates that the tilt threshold of the power tower has been reached, and the external monitoring equipment will sound an alarm.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
