Description

Technical Field

[0001] This utility model belongs to the field of power transmission line monitoring technology, specifically relating to a power transmission line galloping monitoring device. Background Technology

[0002] As a crucial component of the power system, the safe and stable operation of transmission lines directly impacts the reliability and stability of power supply. In the natural environment, transmission lines are frequently affected by meteorological factors such as wind, rain, and snow. Wind-induced galloping is a common cause of transmission line faults. Transmission line galloping refers to a low-frequency, high-amplitude self-excited vibration phenomenon generated by wind on transmission lines. This vibration leads to reduced conductor spacing, accelerated wear of hardware, and in severe cases, even line tripping or wire breakage, posing a serious threat to the safe operation of the power system. To effectively monitor transmission line galloping, promptly detect potential faults, and ensure the safe and stable operation of transmission lines, transmission line galloping monitoring devices have emerged. Traditional galloping monitoring devices installed on transmission lines generally consist of a monitoring unit, a mounting bracket, and a galloping sensor installed within the monitoring unit. During installation, to ensure a stable connection between the monitoring unit and the mounting bracket, pressure sealant is typically applied to the top of the monitoring unit and the bottom of the mounting bracket.

[0003] However, existing traditional motion monitoring devices have many shortcomings in their structural design:

[0004] On the one hand, traditional galloping monitoring devices mostly only have circumferential grooves on their rubber seals to limit the rotational displacement of the device, without any axial limiting measures. When these devices are installed on power transmission lines, the lines are subjected to various external forces during operation, such as wind and changes in conductor tension. These forces can cause the monitoring devices to shift axially on the lines, resulting in positional deviations. This deviation not only affects the accurate acquisition of galloping parameters and reduces the reliability of the monitoring data, but also makes it impossible for the device to be stably fixed in its intended position on the power transmission line. Long-term operation may damage the device and further reduce monitoring stability.

[0005] On the other hand, traditional vibration monitoring devices lack an effective connection between the adhesive tape and the main body of the device. During installation at heights, installers must work at high altitudes above power lines, in a complex and dangerous environment. Due to the weak connection between the adhesive tape and the main body, it is prone to detachment due to external impacts, wind, or other factors. This detachment not only affects the installation progress, increasing time and cost, but may also require installers to perform high-altitude re-installation, significantly increasing installation difficulty and risk, and reducing ease of installation.

[0006] Therefore, this utility model proposes a power transmission line galloping monitoring device. Utility Model Content

[0007] The purpose of this invention is to provide a power transmission line galloping monitoring device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a transmission line galloping monitoring device, comprising a monitoring instrument body and a fixing bracket respectively fixed to the bottom and top of the transmission line, wherein fixing brackets are fixed on both sides of the fixing brackets, and fixing brackets are fixed on both sides of the monitoring instrument body, and further comprising...

[0009] The three-section combined pressure adhesive is installed on the bottom surface of the fixed bracket and the top surface of the monitoring instrument body. The three-section combined pressure adhesive consists of two end pressure adhesives and a central pressure adhesive set between the two end pressure adhesives. The inner surfaces of the end pressure adhesives and the central pressure adhesive are respectively provided with axial limiting grooves and circumferential grooves.

[0010] And a bolt assembly disposed between fixed seat two and fixed seat one.

[0011] Preferably, it also includes a snap-fit ​​connection structure, wherein a snap-fit ​​connection structure is provided between the three-section combined adhesive and the monitoring instrument body, and between the three-section combined adhesive and the fixed bracket.

[0012] Preferably, the snap-fit ​​connection structure includes L-shaped locking feet and L-shaped locking slots. Multiple L-shaped locking feet are fixed on the top surface of the monitor body and the bottom surface of the fixed bracket, and two L-shaped locking slots corresponding to the L-shaped locking feet are opened on the outer surfaces of the end pressure adhesive and the center pressure adhesive.

[0013] Preferably, the side of the L-shaped clamping foot is provided with an arc-shaped guide surface, and the end of the arc-shaped guide surface is a plane.

[0014] Preferably, both corners at the top of the fixed support are chamfered, and both corners at the bottom of the monitoring instrument body are chamfered.

[0015] Preferably, the bolt assembly includes a long bolt and a nut, the top end of the long bolt pressing against the top surface of the second fixing seat, the bottom end of the long bolt passing through the second fixing seat and extending to the bottom of the first fixing seat, and the nut being fitted onto the bottom surface of the long bolt and abutting against the bottom surface of the first fixing seat.

[0016] Preferably, both the surface of the second fixing seat and the surface of the first fixing seat have two bolt holes for the bottom end of the long bolt to pass through.

[0017] Preferably, a monitoring head is provided at the front end of the monitoring instrument body, and a motion sensor is installed inside the monitoring instrument body.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: The transmission line galloping monitoring device of this application, through the design of a three-section combined pressure adhesive, has axial limiting grooves at the ends of the front and rear sections and a circumferential groove in the middle section, which can limit the monitoring device in all directions. After the monitoring device is installed, the axial limiting groove can effectively prevent the monitoring device from axial displacement on the transmission line, and the circumferential groove can limit the rotational displacement of the monitoring device, thereby ensuring that the monitoring device is stably limited and will not rotate or slide back and forth, greatly improving the stability of the monitoring device on the transmission line and ensuring the accuracy and reliability of the monitoring data. At the same time, this application designs a snap-fit ​​connection structure between each pressure adhesive and the main body of the monitoring device. This connection structure allows the pressure adhesive to be stably locked on the device. During high-altitude installation, even if affected by external force collisions, wind, or other factors, the pressure adhesive is not easy to fall off, avoiding problems such as reinstallation due to pressure adhesive falling off, reducing installation difficulty, improving installation convenience, reducing installation time and cost, and also reducing the safety risks for installers.
