Description

Technical Field

[0001] The present invention relates to the technical field of cable de-icing, and particularly relates to an automatic de-icing device for overhead cables in a substation. Background Art

[0002] Icing on overhead lines can cause accidents such as system stability damage, icing-induced pole collapse and wire breakage, ice flashover, and galloping, which will not only cause large-scale power outages, but in severe cases, even threaten the personal safety of residents near the lines. The existing de-icing methods mainly include manual de-icing by knocking with bamboo poles. Workers have to climb onto the high-voltage towers in cold weather, often working for more than 10 hours, and sometimes even working at night. The work difficulty and potential safety hazards are imaginable. Summary of the Invention

[0003] The present invention provides an automatic de-icing device for overhead cables in a substation.

An installation frame is installed at the bottom of the drone. The installation frame includes two spaced-apart installation side plates. An installation top plate is arranged between the two installation side plates. Two spaced-apart and horizontally arranged threaded rods are rotatably arranged between the two installation side plates. The two ends of the threaded rod are respectively rotatably connected to the two installation side plates. Two spaced-apart moving plates are threadedly connected to the threaded rod. A support frame is fixedly connected to the bottom of the moving plate. A de-icing device is installed at the bottom of the support frame. The de-icing device includes a driving motor I, which is vertically installed at the bottom of the support frame. A de-icing roller is connected to the rotating shaft of the driving motor I. A plurality of de-icing blades are distributed on the outer circumference of the de-icing roller.

[0005] The threaded rod is connected to a driving motor I, and the driving motor I is fixedly installed outside the installation side plate.

[0006] A groove is radially formed in the de-icing roller, and the longitudinal section of the groove is in a horn-shaped structure.

[0007] The de-icing blades are installed in the groove, and the shape of the de-icing blade is adapted to the groove.

[0008] A partition is fixedly connected to the bottom of the installation top plate, and the threaded rods are respectively located on both sides of the partition.

[0009] The support frame is in a portal structure and includes two support side plates and a support top plate.

[0010] Guide blocks are arranged on both side surfaces of the partition along its length direction. Guide grooves are formed on one side surface of the two support side plates close to the guide blocks, and the guide grooves are matched with the guide blocks.

[0011] The technical solution of the present invention has the following positive effects: Driven by a drone, the present invention can be lifted and lowered arbitrarily, which is convenient to use and reduces the labor intensity of workers; the distance between the ice melting rollers can be adjusted to adapt to cables of different diameters; the ice melting rollers are provided with trumpet-shaped grooves, and the shape of the ice melting blades is adapted to the grooves, increasing the contact area with the cable and improving the ice melting effect.

DETAILED DESCRIPTION OF THE INVENTION

[0017] As Figures 1-4 shown, an automatic ice melting device for overhead cables of a substation includes a drone 1. A mounting frame 2 is installed at the bottom of the drone 1. The mounting frame 2 includes two spaced mounting side plates 3. An mounting top plate 4 is arranged between the two mounting side plates 3. Two spaced and horizontally arranged threaded rods 5 are rotatably arranged between the two mounting side plates 3. The two ends of the threaded rod 5 are respectively rotatably connected to the two mounting side plates 3. Two spaced moving plates 7 are threadedly connected to the threaded rod 5. The bottom of the moving plate 7 is fixedly connected to a support frame 8. An ice melting device is installed at the bottom of the support frame 8. The ice melting device includes a driving motor I 9. The driving motor I 9 is vertically installed at the bottom of the support frame 8. The rotating shaft of the driving motor I 9 is connected to an ice melting roller 10. A plurality of ice melting blades 11 are distributed on the outer circumference of the ice melting roller 10; the threaded rod 5 is connected to a driving motor II 9. The driving motor II 9 is fixedly installed on the outside of the mounting side plate 3.

[0018] Specifically, the drone is controlled to rise above the cable. The two ice melting rollers 10 are located on both sides of the cable. The driving motor two 17 is started to rotate the threaded rod 5. Two opposite threads are arranged on the left and right sides of the threaded rod 5, so that the two moving plates 7 move towards the middle or towards both ends at the same time. The driving motor one 9 is started to drive the ice melting rollers 10 to rotate, so that the whole device can move along the cable. When moving, the ice melting blades 11 will melt and break the ice on the cable.

[0019] The ice melting roller 10 is radially provided with a groove 12, and the longitudinal section of the groove 12 is a horn-shaped structure; the ice melting blade 11 is installed in the groove 12, and the shape of the ice melting blade 11 is adapted to the groove 12. Specifically, setting the groove 12 in a horn shape can increase the contact area with the cable and the ice melting effect is better.

[0020] The bottom of the installation top plate 4 is fixedly connected with a partition plate 13, and the threaded rod 5 is respectively located on both sides of the partition plate 13.

[0021] The support frame 8 is a portal structure, and the support frame 8 includes two support side plates 6 and a support top plate 14.

[0022] Guide blocks 15 are arranged on both side surfaces of the partition plate 13 along its length direction. Guide grooves 16 are opened on one side surface of the two support side plates 6 close to the guide blocks 15, and the guide grooves 16 are matched with the guide blocks 15; specifically, when the moving plate 7 moves on the threaded rod 5, the guide blocks 15 and the guide grooves 16 can limit the moving plate 7 to prevent it from rotating.

[0023] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
