[0002] With the continuous growth of modern power demand, extra-high voltage and ultra-high voltage transmission lines are increasingly widely used. The efficient operation and safety monitoring of these transmission lines become particularly important. Therefore, it is of great practical significance to develop fixing devices for monitoring equipment applicable to different types of transmission towers.

[0003] At present, most of the common installation methods of transmission line monitoring equipment on the market are based on the angle steel tower structure, and such devices have good stability and adaptability on the angle steel tower. However, with the development of transmission technology, extra-high voltage and ultra-high voltage transmission lines have adopted cylindrical tower structures, and the existing monitoring equipment fixing devices have insufficient adaptability to cylindrical tower structures.

[0004] In the prior art, there are relatively few fixing devices for monitoring equipment for cylindrical towers, and most of them are complex in design and cumbersome in installation steps, requiring a large amount of manpower and time for installation, increasing the project cost and construction period, with high maintenance costs, and unable to fully meet the actual application requirements. Moreover, due to the imperfect design of the prior art, the fixing stability of the monitoring equipment on the cylindrical tower is poor, and it is easily affected by external environmental factors (such as wind force, vibration, etc.), affecting the long-term reliable operation of the equipment. Content of the Utility Model

[0005] In view of the above problems, the utility model provides a fixing device for monitoring equipment of extra-high voltage and ultra-high voltage transmission lines, which is clamped and fixed on the cylindrical tower of the transmission line through an arch-shaped structural member, and the monitoring equipment is fixed on the fixing platform on the arch-shaped structural member, so as to fix the monitoring equipment on the cylindrical tower of the transmission line. It can not only be firmly fixed on the surface of the cylindrical tower widely used in extra-high voltage and ultra-high voltage transmission lines, but also improve the safety and stability of the monitoring equipment, greatly simplify the installation process of the monitoring equipment on the cylindrical tower, reduce the installation steps and labor costs, and improve the installation efficiency.

[0006] To achieve the above object, the utility model provides a fixing device for monitoring equipment of extra-high voltage and ultra-high voltage transmission lines, comprising: two groups of adapted arch-shaped structural members, the arched concave surfaces of the two groups of arch-shaped structural members face each other and are fixedly installed on the cylindrical tower of the transmission line;

[0007] A fixing platform is fixedly welded on the arched convex surface of one of the groups of arch-shaped structural members, and the monitoring equipment to be fixed is fixed on the fixing platform.

[0008] In the above technical solution, preferably, raised ribs are distributed on the arched concave surfaces of the two groups of arched structural members, and the raised ribs are perpendicular to the arched edges of the arched structural members.

[0009] In the above technical solution, preferably, the radian of the arched concave surface of the two groups of arched structural members is adapted to the radian of the tower body of the cylindrical tower.

[0010] In the above technical solution, preferably, the radian of the arched structural member is 130-140 mm, and the width is 90-110 mm. Mounting holes are symmetrically arranged on both sides of the arch of the arched structural member, and the two groups of arched structural members are clamped and fixed on the cylindrical tower by bolts installed in the mounting holes.

[0011] In the above technical solution, preferably, fixing holes are preset on the fixed platform, and the monitoring device is fixed to the fixed platform by screwing or riveting through the fixing holes.

[0012] In the above technical solution, preferably, the fixing device for the monitoring device of ultra-high voltage and extra-high voltage transmission lines further includes a convex-shaped structural member. A transfer hole is provided on the protruding surface of the convex-shaped structural member, the monitoring device is fixed to the transfer hole, screw holes are provided on the bottom surfaces of both sides of the convex-shaped structural member, and the convex-shaped structural member is fixed to the fixed platform by bolts.

[0013] In the above technical solution, preferably, the protruding height of the protruding surface of the convex-shaped structural member is 15-25 mm.

[0014] In the above technical solution, preferably, the screw holes on the bottom surfaces of both sides of the convex-shaped structural member are respectively set as circular and rounded rectangular, and the convex-shaped structural member is fixed to the fixed platform through the circular screw hole and the rounded rectangular screw hole respectively.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: The monitoring device is fixed to the cylindrical tower of the transmission line by clamping with the arched structural member, and the monitoring device is fixed through the fixed platform on the arched structural member, realizing the fixation of the monitoring device on the cylindrical tower of the transmission line. It can not only be firmly fixed on the surface of the cylindrical tower widely used in ultra-high voltage and extra-high voltage transmission lines, but also improve the safety and stability of the monitoring device, greatly simplify the installation process of the monitoring device on the cylindrical tower, reduce the installation steps and labor costs, and improve the installation efficiency. The raised ribs inside the arched structural member increase the friction force, effectively reducing the risk of the device moving under external environmental factors such as wind force and vibration. In addition, the split design of the convex-shaped structural member can disperse the device acting force, improve the safety factor of the installation components, ensure the long-term stable operation of the device, and reduce the maintenance and replacement frequency.
