Description

Technical Field

[0001] This utility model relates to the field of wind vibration detection technology for high-voltage transmission lines, specifically a wind vibration detection device for high-voltage transmission line conductors. Background Technology

[0002] The wind vibration detection device for high-voltage transmission lines is a device used to monitor the vibration of transmission line conductors under wind load. Its main function is to ensure the safe and stable operation of transmission lines and avoid fatigue damage, wire breakage, and other accidents caused by long-term conductor vibration.

[0003] Wind vibration detection devices generally include mounting components and accelerometers. The accelerometer is fixed to the conductor by the mounting components and directly measures the acceleration signal of the conductor vibration. By analyzing the relationship between acceleration and vibration amplitude and frequency, the vibration characteristics of the conductor can be obtained. Existing mounting components mostly use rigid fixing (such as metal clamps for direct clamping) or a single rubber buffer. During vibration, rigid impacts are easily generated between the mounting components and the conductor, which can easily lead to distortion of the acceleration signal. Long-term use may damage the accelerometer due to fatigue, and long-term vibration friction can also cause wear on the conductor insulation layer. Therefore, improvements are needed.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5 The present invention provides an embodiment of a high-voltage transmission line conductor wind vibration detection device, comprising an installation component 1, an acceleration sensor 3, a conductor body 4 and a clamping component 5. The acceleration sensor 3 is fixed to the top of the installation component 1 by a bracket 2, and the conductor body 4 passes through the center of the installation component 1.

[0023] The mounting component 1 and the acceleration sensor 3 are installed in the middle section of the conductor body 4 of the high-voltage transmission line to monitor the vibration acceleration of the conductor body 4 in real time.

[0024] The two ends of both sides of the mounting part 1 are fixedly connected by bolts 12, and both ends of the bolts 12 are fixed and locked by nuts 13;

[0025] The mounting component 1 is spliced ​​on both sides by bolts 12 and nuts 13 to form a cavity that wraps the main body 4 of the wire. The mounting component 1 can be flexibly assembled and disassembled by the combination of bolts 12 and nuts 13.

[0026] The end of the nut 13 near the mounting part 1 is tightly fitted to the mounting part 1 through the buffer pad 19, and the end of the buffer pad 19 near the nut 13 is provided with a bulge 20. The bulge 20 and the nut 13 are connected by the elastic element 21.

[0027] The buffer pad 19 is usually made of elastic material such as silicone. When the nut 13 is tightened, the buffer pad 19 is compressed and undergoes elastic deformation, forming a reverse thrust and adhering tightly to the surface of the mounting part 1.

[0028] The elastic element 21 connects the bulge 20 and the nut 13. The elastic element 21 is made of rubber. The elastic element 21 offsets the preload reduction of the nut 13 caused by vibration through its own deformation, and maintains the tightness of the nut 13.

[0029] Both ends of the mounting component 1 are provided with clamping components 5. The side of the clamping component 5 closest to the conductor body 4 is connected to the conductor body 4 through a limiting plate 8.

[0030] The two ends of the mounting part 1 are respectively passed through the adjusting screw 6, and the adjusting screw 6 and the mounting part 1 are fixed and locked by the fastening nut 7.

[0031] Rotate the adjusting screw 6 to push the clamping parts 5 on both sides to move radially along the conductor body 4. The limiting plate 8 is symmetrically distributed about the conductor body 4, and the side of the limiting plate 8 closest to the conductor body 4 has anti-slip protrusions 18 evenly distributed. The limiting plate 8 contacts and presses against the conductor body 4 through the anti-slip protrusions 18. Then rotate the fastening nut 7 to lock the adjusting screw 6 to prevent the clamping parts 5 from loosening.

[0032] The clamping member 5 has grooves 14 evenly distributed on the side near the limiting plate 8, and each groove 14 is provided with a buffer member 15. The buffer member 15 adopts a hollow rubber structure, and each buffer member 15 is provided with a spring 16.

[0033] Guide grooves 17 are provided on both sides of the interior of the groove 14, and guide blocks matching the guide grooves 17 are provided on both sides of the buffer 15.

[0034] When the conductor body 4 generates low-frequency vibration, the rubber buffer 15 undergoes elastic deformation, converting vibration energy into heat energy. The deformation, through the sliding cooperation between the guide block and the guide groove 17, ensures that the buffer 15 is compressed in a preset direction to avoid displacement. When the conductor body 4 generates high-frequency vibration, the spring 16 provides rigid support, attenuating the amplitude of high-frequency vibration, forming a composite buffer system of "double-stage vibration reduction" to prevent distortion of the acceleration sensor signal.

[0035] The buffer 15 is evenly arranged along the circumference of the conductor body 4, so that the pressure distribution of the limiting plate 8 when clamping the conductor body 4 is more uniform, and local overload damage to the conductor body 4 is avoided.

[0036] A control box 11 is provided on one side of the bracket 2. A motherboard 22 is provided in the center of the control box 11, and a central chip 23, a communication module 24 and a GPS module 25 are arranged on the motherboard 22 in sequence.

[0037] Accelerometer 3 monitors the vibration acceleration of conductor body 4 in real time and outputs analog signals to main board 22 in control box 11. Central chip 23 filters and amplifies the signal and calculates parameters such as vibration frequency and amplitude. Communication module 24 sends the processed data to remote monitoring center. GPS module 25 obtains device location information in real time and binds it with vibration data to facilitate fault location.

[0038] The inner wall of the control box 11 is provided with a shielding layer 26, which is made of metal wire and can effectively block external electromagnetic interference.

[0039] A solar thin film 9 is provided on the side of the bracket 2 away from the control box 11, and a storage battery 10 is provided at one end of the bottom of the bracket 2. The solar thin film 9 converts solar energy into electrical energy to power the device, and the storage battery 10 can store excess electrical energy to continuously power the device when there is insufficient light, such as at night or on cloudy days.

[0040] The specific models and specifications of the accelerometer 3, central chip 23, communication module 24 and GPS module 25 need to be determined based on the specifications and parameters of the device. The selection and calculation method is existing technology, so it will not be described in detail.

[0041] Working Principle: In this embodiment, the mounting component 1 and the acceleration sensor 3 are installed in the middle section of the high-voltage transmission line. The two sides of the mounting component 1 are spliced ​​together by bolts 12 and nuts 13 to form a cavity that encloses the conductor body 4. Through the combination of bolts 12 and nuts 13, the mounting component 1 can be flexibly assembled and disassembled. When installing the detection device, the operator can easily install it onto the conductor body 1. The buffer pad 19, the bulge 20, and the elastic element 21 together constitute an elastic buffer system. When the conductor body 4 vibrates and is transmitted to the mounting component 1, the system can absorb the vibration energy, reduce the risk of loosening of the nut 13 due to vibration, and at the same time reduce the rigid collision and wear between the nut 13 and the mounting component 1. Rotating the adjusting screw 6 pushes the clamping components 5 on both sides to move radially along the conductor body 4. The limiting plate 8 contacts and presses against the conductor body 4 through the anti-slip protrusion 18. Then, rotating the fastening nut 7 locks the adjusting screw 6 to prevent the clamping components 5 from loosening. The inner groove 14 of the clamping component 5 An embedded rubber buffer 15 is used. When the conductor body 4 generates low-frequency vibration, the rubber buffer 15 undergoes elastic deformation, converting vibration energy into heat energy. The deformation is achieved through the sliding cooperation between the guide block and the guide groove 17, ensuring that the buffer 15 is compressed in a preset direction to avoid displacement. When the conductor body 4 generates high-frequency vibration, the spring 16 provides rigid support, attenuating the amplitude of high-frequency vibration, forming a "double-stage vibration reduction" composite buffer system to prevent distortion of the accelerometer signal. The accelerometer 3 monitors the vibration acceleration of the conductor body 4 in real time and outputs an analog signal to the main board 22 in the control box 11. The central chip 23 filters and amplifies the signal, calculates parameters such as vibration frequency and amplitude, and the communication module 24 sends the processed data to the remote monitoring center. The GPS module 25 obtains the device location information in real time and binds it with the vibration data for easy fault location. In addition, the solar thin film 9 converts light energy into electrical energy and stores it in the battery 10, supporting the device to work in continuous rainy weather.
