[0007] Preferably, the lower placing plate is in a semi-arc structure.

[0008] By adopting the above technical scheme: the lower placing plate in semi-arc structure can better fit the shape of the power transmission and transformation line electric wire.

[0009] Preferably, the plurality of U-shaped seats are equidistantly distributed.

[0010] By adopting the above technical solution, the U-shaped seats with equal spacing can make the power transmission and transformation line wires bear force evenly on the fixing device.

[0011] Preferably, the lowering plate corresponds to the position of the fixing mechanism.

[0012] By adopting the above technical solutions, the entire fixing process becomes smoother and more efficient.

[0013] Preferably, the fixing mechanism includes a fixing plate, an insulating pad is provided on the inner surface of the fixing plate, two mounting plates are fixedly installed on the left and right ends of the fixing plate, movable rods are provided on the upper ends of the four mounting plates, limit plates are provided on the upper ends of the four movable rods, and a screw is movably installed on the middle part of the outer surface of the fixing plate through a movable sleeve, and a handle is fixedly installed on the upper end of the screw.

[0016] By adopting the above technical solution, the semi-circular structure can better fit the shape of the wire, providing comprehensive fixation and insulation protection for the wire.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In this invention, the mounting base can be firmly fixed in a suitable position by threaded rods and bolts, ensuring the stability of the entire device. When the wire is passed between the lower plate and the fixed plate, the outer surface of the wire is in contact with the inner surface of several insulating sleeves. The insulating sleeves play a good insulating role, ensuring the safe operation of the power transmission and transformation line. When the wire is pulled for installation, several movable rollers cooperate to make it easy for workers to move the wire, saving more effort. At the same time, the rolling of the movable rollers avoids direct hard friction between the wire and the fixed device, avoiding additional damage to the wire and extending the service life of the wire.

[0019] In this invention, rotating the handle drives the screw to rotate, which in turn moves the fixing plate downwards until the insulating pad on the inner surface of the fixing plate is tightly fitted against the upper outer surface of the wire. This design makes operation convenient and quick. The insulating pad further enhances the insulation performance of the fixing device and firmly secures the wire, preventing it from loosening or shifting due to external forces during power transmission and transformation. This ensures the stable operation of the power transmission line, reduces the probability of faults caused by loose wires, and improves the reliability and safety of power transmission and transformation.

[0028] Please see Figures 1-4 This utility model provides a technical solution:

[0029] A wire insulation fixing device for power transmission and transformation lines includes a mounting base 1. Support rods 2 are provided at the four corners of the upper end of the mounting base 1. A top plate 3 is provided at the upper end of the four support rods 2. A placement component 4 is provided at the upper end of the mounting base 1. Four movable holes 10 are provided at the upper end of the top plate 3. A fixing mechanism 5 is provided inside the four movable holes 10. Threaded rods 6 are provided at the lower left and lower right parts of the mounting base 1. Fastening nuts 7 are provided on the outer surface of the two threaded rods 6. Fixing ears 8 are provided at the left and right ends of the mounting base 1. Two screw holes 9 are provided at the upper end of the two fixing ears 8. Bolts 11 are threaded into the four screw holes 9.

[0030] In this embodiment, the placement component 4 includes a lowering plate 41. Support columns 42 are provided on the lower left and lower right sides of the outer surface of the lowering plate 41. A plurality of U-shaped seats 43 are provided on the inner surface of the lowering plate 41. Movable shafts 44 are provided inside each of the U-shaped seats 43. Movable rollers 45 are provided on the outer surfaces of the movable shafts 44. Insulating sleeves 46 are provided on the outer surfaces of the movable rollers 45. The lowering plate 41 has a semi-arc structure. The U-shaped seats 43 are evenly distributed. The lowering plate 41 corresponds to the position of the fixing mechanism 5.

[0031] Through the above scheme: the lowering plate 41 has a semi-arc structure, which can better fit the shape of the power transmission line wire, providing support and guidance for the wire. The support column 42 is used to support the lowering plate 41 and keep it in a stable position. The movable roller 45 on the movable shaft 44 can rotate freely around the movable shaft 44. When the wire is placed on the lowering plate 41, the movable roller 45 rotates accordingly, reducing the friction between the wire and the lowering plate 41 and facilitating the wire. The insulating sleeve 46 on the outer surface of the movable roller 45 plays an insulating role to prevent the wire from leaking electricity.

[0032] In this embodiment, the fixing mechanism 5 includes a fixing plate 51, an insulating pad 52 is provided on the inner surface of the fixing plate 51, two mounting plates 53 are fixedly installed on the left and right ends of the fixing plate 51, movable rods 54 are provided on the upper ends of the four mounting plates 53, and limit plates 55 are provided on the upper ends of the four movable rods 54. A screw 56 is movably installed on the middle part of the outer surface of the fixing plate 51 through a movable sleeve, and a handle 57 is fixedly installed on the upper end of the screw 56. The four movable rods 54 are respectively inserted and movably installed inside the four movable holes 10. The fixing plate 51 and the insulating pad 52 are both semi-arc structures.

[0033] With the above design: both the fixing plate 51 and the insulating pad 52 have a semi-circular structure, which can better fit the wire, providing fixation and insulation protection for the wire. The movable rod 54 makes the up-and-down movement more stable. The screw 56 is connected to the fixing plate 51 through a movable sleeve, and turning the handle 57 can move the screw 56 up and down. When the screw 56 moves downward, it drives the fixing plate 51 and the insulating pad 52 to move upward, clamping and fixing the wire; when the screw 56 moves upward, the fixing plate 51 and the insulating pad 52 release the wire, making it easier to adjust the wire.

[0034] It should be noted that this utility model is a wire insulation fixing device for power transmission and transformation lines. In the process of use, the entire mounting base 1 is first fixed in a suitable position by threaded rod 6 and bolt 11. During fixing, the wire is passed between the lower plate 41 and the fixing plate 51, so that the outer surface of the wire is in contact with the inner surface of several insulating sleeves 46. When the wire is pulled during installation, the cooperation of several movable rollers 45 makes it easy for the staff to move the wire, which is more labor-saving and will not cause additional damage to the wire. After the adjustment is completed, the screw 56 is easily rotated by turning the handle 57, which in turn makes it easy to move the fixing plate 51 downward until the insulating pad 52 on the inner surface of the fixing plate 51 is tightly in contact with the upper part of the outer surface of the wire, thus fixing the wire stably.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
