Description

Technical Field

[0001] This utility model relates to the field of power transmission line monitoring technology, and specifically to an online monitoring device for micro-wind vibration of power transmission lines. Background Technology

[0002] Online monitoring of transmission line vibration under light wind is a system that uses sensors and monitoring technology to monitor the vibration of transmission lines in real time under the influence of light wind. Its working principle is as follows: vibration sensors installed on the transmission line collect conductor vibration signals, which are then collected, converted, and preliminarily processed by a data acquisition unit. The data is then transmitted to the monitoring center via a wireless communication module, where analysis software analyzes the data to obtain vibration characteristic parameters and determine the differential vibration state of the line. The system consists of a sensor layer, a data transmission layer, and a monitoring center layer. It is of great significance, ensuring the safe operation of the line, timely detection and early warning of abnormal vibrations to prevent faults; extending the service life of the line and allowing for more rational scheduling of maintenance; optimizing line design and operation and maintenance by providing data support; and improving the operating efficiency of the power system, reducing power outages, and ensuring a reliable power supply.

[0003] According to the public announcement (CN215726082U), a micro-wind vibration online monitoring device for transmission lines is disclosed. This technology discloses that the device includes a base shell, a top cover bolted to the top of the base shell, a wind speed and direction mechanism bolted to the top of the top cover, an eddy current displacement sensor inside the base shell, a support frame with an anemometer and a wind direction indicator on the top of the support frame, a warning light on the top of the support frame, and a circuit board bolted to the inside of the base shell with a microcontroller chip soldered to the top of the circuit board. The eddy current displacement sensor monitors the vibration of the transmission line under micro-wind conditions, and the anemometer and wind direction indicator in the wind speed and direction mechanism monitor the wind speed and direction affecting the transmission line. This gives the micro-wind vibration online monitoring device multi-functional characteristics, facilitating timely detection of problems and maintenance needs by personnel, and improving the efficiency of locating the device.

[0004] However, the above technical solution uses the snap-fit ​​grooves on the bottom shell and top cover to snap onto the power transmission line body. Since the outer shell of the power line is generally made of plastic, this snap-fit ​​method has a certain degree of flexibility. After long-term use, thermal expansion and contraction will cause it to loosen. In severe weather such as strong winds and heavy rain, the device is easily blown outward and tilted, resulting in inaccurate monitoring results.

[0005] To address the aforementioned issues, this application proposes an online monitoring device for micro-wind vibration of transmission lines. Utility Model Content

[0006] This utility model addresses the technical problems existing in the prior art by providing an online monitoring device for micro-wind vibration of power transmission lines.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: an online monitoring device for micro-wind vibration of transmission lines, including an upper shell and a lower shell, a cover plate is fixedly connected to the upper surface of the upper shell, a fixing component is provided inside the upper shell, and reinforcing components are snapped onto the left and right sides of the upper shell and the lower shell.

[0008] The fixing assembly includes a screw, a first gear, and a second gear. The upper end of the screw is fixedly connected to the first gear, and the side surface of the first gear is meshed with the second gear.

[0009] The reinforcing component includes a connecting plate and an arc-shaped reinforcing plate, and the connecting plate has a slot inside.

[0010] Preferably, an anemometer and a wind vane are mounted on the upper surface of the cover plate, and a control chip is fixedly connected to the lower surface of the cover plate. External wind speed and direction signals are collected by the anemometer and wind vane, processed by the control chip, and then uploaded to the cloud platform.

[0011] Preferably, both the upper and lower housings are equipped with snap-fit ​​assemblies. Each snap-fit ​​assembly includes a slider, a locking block, and a spring. One end of the slider is fixedly connected to the locking block, and the end of the slider away from the locking block is fixedly connected to the spring. The spring springs the locking block on the slider into a slot, achieving the effect of quickly assembling and reinforcing the component using the snap-fit ​​assembly.

[0012] Preferably, a pull rod is fixedly connected inside the slider, and a pull ring is fixedly connected to the end of the pull rod away from the slider. By pulling the pull rod, the pull ring pulls the locking block on the slider backward, thereby separating the reinforcing component from the fixing component. The operation is simple and the disassembly is convenient.

[0013] Preferably, the lower end of the screw is threaded to the lower housing, and wires are provided on the inner walls of the upper and lower housings. The lower housing is pulled upward by the synchronous rotation of the two pull rings, so that the wires are tightly fixed between the upper and lower housings.

[0014] Preferably, a motor is fixedly connected to the upper surface of the cover plate, and a rotating shaft is fixedly connected to the output end of the motor. The lower end of the rotating shaft is fixedly connected to the second gear. By driving the rotating shaft to rotate through the motor, the second gear drives the screws below the two first gears to rotate synchronously, making the process of pulling up and down the housing more coordinated.

[0015] Preferably, a protective shell is fixedly connected to the upper surface of the cover plate. The protective shell protects the motor from rain and snow, preventing it from malfunctioning.

[0016] Preferably, a bolt is inserted inside the slot, and a nut is threaded onto the side surface of the bolt. The bolt and nut work together to secure the upper and lower slots, ensuring that the inner wall of the slot fits snugly against the wire, thus making the connection between the device and the wire more secure.

[0017] The beneficial effects of this utility model are:

[0018] 1. By using the fixing components on the housing, the power transmission line and the micro-wind vibration online monitoring device can be tightly connected together, thereby ensuring that the device will not be blown askew in severe weather, ensuring its normal use, improving the accuracy of monitoring results, and the pressure between the power transmission line and the arc-shaped clamp can be automatically adjusted. By increasing the pressure, the friction is increased, making it less likely for the device to tilt or hang upside down on the power line.

[0019] 2. Based on the average annual wind force at this location, a set of reinforcing components is added to the side of the casing. By adjusting the contact area between the fixing components and the outer surface of the transmission line, the reinforcing components can work together with the fixing components to form a linkage effect, further increasing the contact area and thus improving the fixing effect. This makes the device more stable during use, and the installation of the reinforcing components and the casing is convenient and simple. Attached Figure Description

[0029] Reference Figure 1-4 An online monitoring device for micro-wind vibration of power transmission lines includes an upper housing 1 and a lower housing 3. A cover plate 2 is fixedly connected to the upper surface of the upper housing 1. A fixing component is installed inside the upper housing 1. Reinforcing components are snapped onto the left and right sides of both the upper housing 1 and the lower housing 3. An anemometer 4 and a wind vane 5 are installed on the upper surface of the cover plate 2, and a control chip 6 is fixedly connected to the lower surface of the cover plate 2. The anemometer 4 and the wind vane 5 collect external wind speed and direction signals, which are then processed by the control chip 6 and uploaded to the cloud.

[0030] The fixing assembly includes a screw 7, a first gear 8, and a second gear 9. The upper end of the screw 7 is fixedly connected to the first gear 8, and the side surface of the first gear 8 meshes with the second gear 9. Both the upper housing 1 and the lower housing 3 have snap-fit ​​assemblies inside. Each snap-fit ​​assembly includes a slider 13, a locking block 14, and a spring 15. One end of the slider 13 is fixedly connected to the locking block 14, and the end of the slider 13 away from the locking block 14 is fixedly connected to the spring 15. The spring 15 springs the locking block 14 on the slider 13 into the locking groove 12, achieving the effect of quickly assembling the reinforcing assembly using the snap-fit ​​assembly. A pull rod 16 is fixedly connected inside the slider 13, and a pull ring 17 is fixedly connected to the end of the pull rod 16 away from the slider 13. By pulling the pull rod 16, the pull ring 17 pulls the locking block 14 on the slider 13 backward, achieving the separation of the reinforcing assembly from the fixing assembly. The operation is simple and easy to disassemble. The lower end of the screw 7 is threadedly connected to the lower housing 3. Wires 18 are installed on the inner walls of the upper housing 1 and the lower housing 3. The lower housing 3 is pulled upwards by the synchronous rotation of two pull rings 17, which tightly fixes the wire 18 between the upper housing 1 and the lower housing 3. A motor 19 is fixedly connected to the upper surface of the cover plate 2, and a rotating shaft 20 is fixedly connected to the output end of the motor 19. The lower end of the rotating shaft 20 is fixedly connected to the second gear 9. The motor 19 drives the rotating shaft 20 to rotate, thereby enabling the second gear 9 to drive the screws 7 below the two first gears 8 to rotate synchronously, making the process of pulling the lower housing 3 more coordinated. A protective shell 21 is fixedly connected to the upper surface of the cover plate 2. The protective shell 21 protects the motor 19 from rain and snow entering and causing the motor 19 to malfunction.

[0031] The reinforcing assembly includes a connecting plate 10 and an arc-shaped reinforcing plate 11. The connecting plate 10 has a slot 12 inside, and a bolt 22 passes through the slot 12. A nut 23 is threaded onto the side surface of the bolt 22. The bolt 22 and nut 23 work together to secure the upper and lower slots 12, ensuring the inner wall of the slot 12 fits snugly against the wire 18, thus making the connection between the device and the wire 18 more secure.

[0032] Working principle:

[0033] During installation, first, the upper housing 1 is clipped above the wire 18, then the screw 7 is inserted into the lower housing 3. The motor 19 is started to drive the rotating shaft 20 to rotate, and then the screw 7 below the two gears 8 is driven to rotate synchronously through the second gear 9, so that the lower housing 3 is automatically pulled up. The upper housing 1 and the lower housing 3 together clamp the wire 18. When the upper housing 1 and the lower housing 3 become loose due to environmental influences, the motor 19 can be controlled from the cloud through the control chip 6. The motor 19 drives the screw 7 to pull the lower housing 3 tighter. When connecting the reinforcing component, simply align the slot 12 on the connecting plate 10 with the slot 14 and insert and lock it in place. The operation is simple and convenient. Then tighten the bolt 22 and nut 23 so that the upper housing 1 and the lower housing 3 are further fixed to the wire 18 through the reinforcing component, increasing the contact surface of the fixation, so that the device is not easy to tilt.
