Description

Technical Field

[0001] This utility model relates to the field of power facility maintenance equipment technology, and in particular to an ice-breaking device for overhead transmission lines. Background Technology

[0002] In cold climates, overhead power transmission lines are prone to accumulating ice and snow, which not only increases the burden on the lines but can also lead to serious accidents such as line breaks and tower collapses. Therefore, it is necessary to de-ice overhead power transmission lines.

[0003] An ice-breaking device for overhead transmission lines, such as one disclosed in CN222423171U, includes a drive mounting base, an ice-breaking hammer, and a drive component. The drive mounting base is detachably mounted on the transmission line and moves along the line. The ice-breaking hammer is rotatably mounted on the drive mounting base and performs ice-breaking operations by swinging and striking the transmission line. The drive component is mounted on the drive mounting base and is connected to the ice-breaking hammer, driving the hammer to swing back and forth. This invention uses a drive mounting base to move along the transmission line, and the ice-breaking hammer strikes the line repeatedly during this movement, enabling rapid and effective ice-breaking of transmission circuits. It features a simple structure and convenient operation. However, because this overhead transmission line ice-breaking device is primarily designed for ice breaking of overhead transmission lines, it cannot detect line sag. When the line sags due to excessive weight, it not only affects aesthetics but may also reduce the safe distance between the conductor and the ground, increasing the risk of electric shock.

[0004] Therefore, an ice-breaking device for overhead power transmission lines has been developed that can detect the sag of transmission lines and make timely adjustments. Utility Model Content

[0005] To overcome the shortcomings of existing overhead transmission line ice-breaking devices, which are mainly designed for ice breaking of overhead transmission lines but cannot detect the sag of the transmission line, and which not only affect the aesthetics when the transmission line is too heavy and sags, but may also reduce the safe distance between the conductor and the ground and increase the risk of electric shock, this utility model provides an overhead transmission line ice-breaking device that can detect the sag of the transmission line so as to make timely adjustments.

[0006] The technical implementation scheme of this utility model is as follows: an ice-breaking device for overhead transmission lines, comprising a shell, a connecting plate, a fixing rod, a drone, an alarm, a trigger frame, a spring, a switch, a heating component, and a striking component. Two fixing rods are connected to the upper side of the middle of the shell, and a connecting plate is connected between the upper sides of the fixing rods. A trigger frame is connected to the upper side of the connecting plate, and an alarm is connected to the upper side of the trigger frame. A drone is slidably connected to the trigger frame. Springs are connected between the drone and the front and rear parts of the trigger frame. A switch is connected to the lower part of the drone and is located below the trigger frame. The shell is provided with a heating component that can heat the transmission line, and the shell is also provided with a striking component that can strike the transmission line.

[0007] Furthermore, it also includes rollers, with rollers rotatably connected to the middle and right sides of the outer casing.

[0008] Furthermore, the heating assembly includes clamps, a first motor, a bidirectional lead screw, a guide rod, and heating wires. The guide rod is connected to the upper left part of the outer casing, and clamps are slidably connected to both the front and rear parts of the guide rod. The first motor is connected to the inner side of the left rear part of the outer casing, and the bidirectional lead screw is connected to the output shaft of the first motor. The bidirectional lead screw is rotatably connected to the outer casing, and the clamps are all threadedly connected to the bidirectional lead screw. Heating wires are connected to each clamp.

[0009] Furthermore, all the fixtures are curved.

[0010] Furthermore, the striking assembly includes a rubber rod, a support plate, a bevel gear, a missing gear, and a second motor. The upper left inner side of the housing is connected to two support plates, and the rubber rod is rotatably connected between the support plates. The upper left inner side of the housing is connected to the second motor, which is located between the support plates. The missing gear is connected to the output shaft of the second motor, and the rubber rod is connected to two bevel gears.

[0011] Furthermore, the drone, alarm, switch, first motor, heating wire, second motor, and processor are electrically connected through a control module.

[0012] This invention has the following advantages: When the drone moves along the cable with its outer shell, the cable is placed on the roller. When the cable sags, it pulls the fixing rod, connecting plate and trigger frame downwards. The spring is compressed and contracts, and the trigger frame presses down on the switch, causing the alarm to sound. This achieves the effect of detecting the sag of the power transmission line so that it can be adjusted in time. Attached Figure Description

Detailed Implementation

[0020] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] An ice-breaking device for overhead power transmission lines, such as Figures 1-6 As shown, it includes a housing 1, a connecting plate 2, a fixing rod 3, rollers 6, a drone 7, an alarm 8, a trigger frame 9, a spring 10, a switch 11, a heating component, and a striking component. The upper middle part of the housing 1 is connected to two fixing rods 3 on the left and right sides. The upper sides of the fixing rods 3 are connected to the connecting plate 2. The middle and right sides of the housing 1 are rotatably connected to rollers 6. The upper side of the connecting plate 2 is connected to the trigger frame 9. The upper side of the trigger frame 9 is connected to the alarm 8. The drone 7 is slidably connected to the trigger frame 9. The front and rear parts of the trigger frame 9 are connected to the drone 7 by springs 10. The lower part of the drone 7 is connected to the switch 11, which is located below the trigger frame 9. The housing 1 is equipped with a heating component and a striking component.

[0022] like Figure 1 , Figure 4 and Figure 5As shown, the heating assembly includes clamps 4, a first motor 12, a bidirectional lead screw 13, a guide rod 14, and heating wires 15. The guide rod 14 is connected to the upper left part of the outer casing 1. The clamps 4 are slidably connected to both the front and rear parts of the guide rod 14. The clamps 4 are all arc-shaped to facilitate clamping the cable. The first motor 12 is connected to the inner side of the rear left part of the outer casing 1. The bidirectional lead screw 13 is connected to the output shaft of the first motor 12. The bidirectional lead screw 13 is rotatably connected to the outer casing 1. The clamps 4 are all threadedly connected to the bidirectional lead screw 13. The heating wires 15 are connected to the clamps 4.

[0023] like Figure 1 and Figure 6 As shown, the striking assembly includes a rubber rod 5, a support plate 16, a bevel gear 17, a missing gear 18, and a second motor 19. The upper left inner side of the outer casing 1 is connected to two support plates 16, and the rubber rod 5 is rotatably connected between the support plates 16. The upper left inner side of the outer casing 1 is connected to the second motor 19, which is located between the support plates 16. The missing gear 18 is connected to the output shaft of the second motor 19, and the rubber rod 5 is connected to two bevel gears 17. The drone 7, alarm 8, switch 11, first motor 12, heating wire 15, second motor 19, and processor are electrically connected through a control module.

[0024] When using this utility model, firstly, start the drone 7 and fly it to the side of the overhead power line so that the cable is positioned between the clamps 4. Then, the processor starts the first motor 12 through the control module, which drives the bidirectional lead screw 13 to rotate, so that the clamps 4 move closer to each other along the guide rod 14 to clamp the cable. Then, the heating wire 15 heats the cable to melt the frost on the cable. The drone 7 moves along the cable, which drives the clamps 4 to move, thus completing the de-icing of the entire cable.

[0025] While de-icing the cable, the processor starts the second motor 19 through the control module, which drives the missing gear 18 to rotate, so that the missing gear 18 intermittently meshes with the two bevel gears 17 on the left and right, thereby causing the rubber rod 5 to swing back and forth to knock off the ice and frost.

[0026] When the drone 7 moves the outer shell 1 along the cable, the cable is placed on the roller 6. When the cable droops, it pulls the fixing rod 3, the connecting plate 2 and the trigger frame 9 downward. The spring 10 is compressed and contracts. The trigger frame 9 presses down on the switch 11, causing the alarm 8 to sound an alarm. This allows the detection of the drooping of the power transmission line for timely adjustment. After the cable is released from the roller 6, the spring 10 rebounds, causing the fixing rod 3, the connecting plate 2 and the trigger frame 9 to move upward and reset.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
