[0032] As an example, the transmission assembly is located directly below the drive motor 51, and the transmission assembly comprises a transmission member 61, a sliding block 62 fixed to the transmission member 61 away from the drive motor 51, and a guide block 63 cooperating with the sliding block 62.

The other end of the transmission member 61 is detachably connected with the electric wire 20 through a buckle 64, the guide block 63 is fixedly connected with the inner wall of the box body 30 through welding or bolt fixing, etc., the guide block 63 is provided with a guide groove 602, the guide groove 602 is arranged along the short axis direction of the waist-shaped through hole 601, and the sliding block 62 is slidably arranged in the guide groove 602. The cooperation between the guide block 63 and the sliding block 62 can effectively limit the movement direction of the transmission member 61, ensure the stability and accuracy of the transmission member 61 during movement, and avoid deviation or shaking. In this way, when the drive motor 51 drives the rotating member 52 to rotate so that the sliding rod 522 reciprocatingly slides in the waist-shaped through hole 601, the sliding block 62 on the transmission member 61 will also reciprocatingly slide in the guide groove 602, thereby converting the circular motion of the rotating member 52 into the linear motion of the transmission member 61.

[0033] Further, the transmission member 61 comprises a first transmission block 611, a second transmission block 612 and a mounting block 613, the waist-shaped through hole 601 is arranged on the first transmission block 611, the second transmission block 612 is arranged on one end of the first transmission block 611 along the long axis direction of the waist-shaped through hole 601, the mounting block 613 is L-shaped, one end of the mounting block 613 is connected with the end of the second transmission block 612 away from the first transmission block 611, and the other end of the mounting block 613 is provided with the buckle 64, and the buckle 64 is located below the second transmission block 612.

[0034] Further, one side of the box body 30 is provided with an avoiding hole 603, and the second transmission block 612 is slidably arranged in the avoiding hole 603.

[0035] The power distribution network wire deicing device of the present application further comprises an abutting assembly, which comprises a connecting block 71, an abutting rod 72 connected with the connecting block 71, and an abutting block 73 matched with the abutting rod 72. The connecting block 71 is fixed on the side of the mounting block 613 away from the clasp 64 by welding or bolt connection, etc. The abutting block 73 is fixed on the outer wall of the box 30 by welding or bolt connection, etc., and is located above the second transmission block 612. The abutting block 73 is provided with a plurality of first protrusions 731 and a plurality of second protrusions 732, which are alternately and spacedly arranged along the length direction of the abutting block 73. When the transmission member 61 reciprocates under the driving of the rotating member 52, the connecting block 71 moves together with the mounting block 613, thereby driving the abutting rod 72 to move. The end of the abutting rod 72 will abut against the first protrusions 731 and the second protrusions 732 on the abutting block 73 in sequence during the movement. The stress direction and size of the abutting rod 72 change periodically during the abutting process, thereby generating vibration. The vibration can be transmitted to the wire 20, thereby assisting in removing the ice layer on the wire 20 and improving the deicing efficiency.

[0036] Further, in order to optimize the vibration effect of the abutting assembly, the first protrusions 731 and the second protrusions 732 in the embodiment are designed as semicircular protrusion structures, and the diameter of the first protrusions 731 is greater than that of the second protrusions 732. This design makes the abutting rod 72 generate vibrations of different frequencies and amplitudes when abutting against protrusions of different diameters, which can effectively promote the ice layer to fall off from the wire 20 and further improve the deicing effect. This design does not require an additional power source, but cleverly utilizes the movement of the existing structure to simply and efficiently improve the deicing efficiency and broaden the application range of the device, which has better removal effect on ice layers of different thicknesses and hardnesses.

[0037] Further, the clasp 64 is in a C-shaped structure to facilitate the placement of the wire 20 inside the clasp 64. One end of the opening of the clasp 64 is provided with a mounting groove, and the groove wall of the mounting groove is connected with one end of a clamping block 651 through a spring 652. A push plate 653 is arranged on the clamping block 651 to provide an easy operating force point for the operator. In actual use, the operator can operate the push plate 653 to make the clamping block 651 overcome the elastic force of the spring 652 and retract into the mounting groove. At this time, the opening of the clasp 64 is no longer blocked by the clamping block 651, and the opening space is completely open, so that the wire 20 can be quickly and smoothly placed into the clasp 64. When the wire 20 is accurately placed in position, the push plate 653 is loosened, and the clamping block 651 is ejected from the mounting groove under the restoring force of the spring 652, thereby effectively blocking the opening of the clasp 64 again, so that the wire 20 is stably limited in the clasp 64. During the deicing operation, the wire 20 can be effectively prevented from falling off from the clasp 64, thereby ensuring the stable operation of the entire deicing device.

[0038] In practical application, the use principle of the power distribution network wire deicing device can be: first, the clamping assembly 40 is used to stably install the box 30 on the cross beam 10 of the power distribution network structure, specifically, the fastening bolt 43 is sequentially inserted through the guide hole of the first connecting plate 41 guide part 412, the second connecting part 421 of the second connecting plate 42 and the first connecting part 411 of the first connecting plate 41, and the bolt is tightened, so as to realize the stable connection between the box 30 and the cross beam 10. Then, the actuating plate 653 at the opening of the buckle 64 is actuated, so that the clamping block 651 overcomes the elastic force of the spring 652 and shrinks into the installation groove, the opening of the buckle 64 is opened, after the wire 20 is placed in place, the actuating plate 653 is loosened, the clamping block 651 pops out of the installation groove and shields the opening of the buckle 64, so as to limit the wire 20 in the internal space of the buckle 64.

[0039] Then, the remote control device matched with the driving motor 51 is started, the driving motor 51 starts to operate, the output shaft of the driving motor 51 drives the connecting plate 521 of the rotating part 52 to rotate, and then makes the slide rod 522 perpendicular to the connecting plate 521 to make circular motion. The slide rod 522 slides in the waist-shaped through hole 601 at one end of the transmission part 61, and due to the cooperation of the sliding block 62 and the guide block 63, the circular motion of the slide rod 522 will finally be converted into the reciprocating linear motion of the transmission part 61 along the direction of the guide groove 602. At the same time, the connecting block 71 and the abutting rod 72 provided at the top end of the mounting block 613 in the transmission part 61 will move synchronously, the end of the abutting rod 72 alternately abuts against the first protrusion 731 and the second protrusion 732 spaced apart on the abutting block 73, and vibration is generated and transmitted to the wire 20. Under the driving of the transmission part 61, the wire 20 connected with the buckle 64 makes reciprocating linear motion, and the vibration effect generated by the abutting assembly is combined, so that the ice layer on the wire 20 is efficiently removed.

[0040] In summary, the power distribution network wire deicing device has the advantages that: through the cooperation between the driving assembly and the transmission assembly, the rotating motion of the motor is efficiently converted into the reciprocating linear motion of the wire, the ice layer on the wire is efficiently removed, and the applicability is high. Specifically, the driving assembly converts the rotating motion of the driving motor into the circular motion of the rotating part, providing a power source for subsequent transmission; the transmission assembly accurately converts the circular motion of the slide rod into the reciprocating linear motion of the transmission part through the cooperation between the waist-shaped through hole on the transmission part and the slide rod of the rotating part, and the guiding effect of the sliding block and the guide block, and then drives the wire in the buckle to make reciprocating linear motion, thereby efficiently removing the ice layer on the wire. Further, the abutting assembly is also provided to increase the vibration auxiliary function for the ice removal process of the wire, specifically, when the transmission part drives the wire to move, the abutting rod in the abutting assembly alternately abuts against the first protrusion and the second protrusion on the abutting block, which will generate vibration of a certain frequency acting on the wire, effectively enhancing the ice removal effect and improving the application range of the whole device.
