Description

Technical Field

[0001] The invention relates to the technical field of power transmission line monitoring devices, in particular to a transmission line iron tower fixed monitoring device. Background Art

[0002] Transmission lines are important power engineering facilities that are responsible for efficiently transmitting electricity from power plants to various power consumption areas. Their operating status is directly related to the safety and stability of the entire power grid. At present, transmission lines erected at high altitudes are fixed on towers using connecting fittings. However, transmission lines exposed to complex and harsh natural environments for a long time, especially in windy weather, will experience wear and looseness due to the swing between the fittings and the conductors, causing friction and damage to the connecting fittings fixed on the towers. In severe cases, the transmission line tower may collapse and the line may be disconnected, causing power grid interruption. Commonly used fitting wear detection methods include: (I) UAV inspection: UAVs are used to inspect the overall condition of power transmission lines, and high-definition cameras are used to take aerial photos to understand the condition of hardware. UAV inspections can quickly inspect large areas of power transmission lines and improve the efficiency of hardware wear inspections. However, UAV inspections are limited by shooting angles, and in some cases, the wear of hardware cannot be identified in a timely manner. (ii) Manual ground inspection, where maintenance personnel use telescopes and other observation equipment on the ground to conduct manual observations to understand the actual conditions of hardware and insulators. However, this method is limited by the line of sight of the inspection and cannot intuitively and accurately identify the wear of hardware; (3) Manual tower inspection: Operation and maintenance personnel need to climb up the transmission tower and directly inspect the hardware. The inspection results can provide a relatively accurate comprehensive assessment of the wear of the hardware, but this method is time-consuming and labor-intensive, with a long inspection cycle, high requirements for operation and maintenance personnel, and there are greater safety risks.

[0026] The present invention will be further described below in conjunction with embodiments and drawings: Embodiment 1: As attached Figure 1-8 As shown, the transmission line tower fixed monitoring device includes a connecting hardware 2, two groups of spaced fixing mechanisms 3, and a monitoring component 5. The connecting hardware 2 is arranged on the tower 1, and the connecting hardware 2 is installed between the two groups of fixing mechanisms 3. The fixing mechanism 3 includes a side plate 31 and a clamping component 32. The connecting hardware 2 is installed between the upper parts of the two side plates 31. The clamping component 32 can clamp the transmission wire 100 and can monitor the front and rear vibration of the transmission wire 100. The monitoring component 5 is installed on the connecting hardware 2 to monitor the longitudinal vibration of the transmission wire 100.

[0027] When in use, firstly, the connecting hardware 2 is bolted to the vertical frame structure on the iron tower 1, and then the connecting hardware 2 is adjusted so that the lower end mounting grooves of the side plates 31 installed on both sides of the connecting hardware 2 are placed outside the transmission line 100, so that the clamping assembly 32 clamps and fixes the parts of the transmission line 100 placed in the side plates 31 on both sides, thereby realizing stable and convenient fixation of the connecting hardware 2 on the transmission line 100 and the iron tower 1. The overall operation is simple, and the collected vibration swing frequency and offset wear value are transmitted and communicated in real time through the solar energy data base station fixed on the iron tower 1. The connecting hardware 2 calculates the wear amount in combination with the wear value and the swing frequency, thereby achieving the purpose of real-time monitoring, timely discovering safety hazards, and issuing early warnings.

[0028] The above-mentioned transmission line tower fixed monitoring device can be further optimized and / or improved according to actual needs: Embodiment 2: As attached Figure 3-6 As shown, the fixing mechanism 3 also includes a transmission assembly 33.

Two arc rings 321 with openings facing each other are provided on the outer side of the transmission wire 100. The middle of the arc ring 321 is located in the mounting groove. An end plate 322 is slidably installed on the outer side of each arc ring 321. A first elastic telescopic rod 323 is provided between the end plate 322 and the arc ring 321. A vibration sensor is provided at one end of the first elastic telescopic rod 323. The transmission assembly 33 can drive the two arc rings 321 to clamp the transmission wire 100.

[0029] The transmission component 33 drives the two arc rings 321 with opposite openings to approach each other and clamp the outside of the transmission line 100. One end of the first elastic telescopic rod 323 is installed on the outer end surface of the arc ring 321, and the other end of the first elastic telescopic rod 323 is installed with a vibration sensor. When the transmission line 100 is subjected to swing vibration, the front and back vibration changes will be measured and recorded by the vibration sensor installed on one end of the first elastic telescopic rod 323. The swing amplitude is recorded according to the frequency and amplitude of the vibration, and the offset of the transmission line 100 is calculated according to the acceleration data of the vibration, and then the data is sent to the solar data base station fixed on the tower 1 for real-time communication.

The clamping ring 53 can be clamped on the upper side of the transmission wire 100. The clamping ring 53 elastically connected to the lower end of the second elastic telescopic rod 52 will abut against the upper half of the transmission wire 100. When the transmission wire 100 is vibrated, the longitudinal vibration changes, and the vibration acceleration, frequency and amplitude are measured and recorded by the vibration sensor installed on one side of the second elastic telescopic rod 52. The swing amplitude is recorded according to the frequency and amplitude of the vibration. The offset of the transmission wire 100 is calculated according to the acceleration data of the vibration, and the wear condition of the connection fitting 2 is judged.

The vertical frame structure of the iron tower 1 is clamped between the mounting seat 61 and the pad 62, and fixed by the screw rod 63 and the nut 631. The connection between the screw rod 63 and the nut 631 uses a pressure sensor to judge the tightness, and the position of the pad 62 is moved according to the thickness of the vertical frame structure. It can be applied to the iron tower 1 structure with different thicknesses, and has a wider range of applications.

[0036] Embodiment 9: Monitoring method, the vibration sensor collects the number of swings and the actual wear, and performs real-time transmission communication through the solar data base station fixed on the tower 1, and the connection hardware 2 calculates the wear value based on the wear value and the number of swings.
