Description

Technical Field

[0001] The invention relates to the technical field of power transmission lines, in particular to a snow clearing device for high-voltage cables. Background Art

[0002] Transmission line icing in winter is one of the biggest natural disasters in the power system. When cold raindrops fall on objects with a temperature below freezing (0℃), rime is formed. If it condenses on wires, it forms wire icing. If all wires in a range are covered with ice, this is line icing. For high-voltage wires that transmit electricity over long distances, they rely on iron towers for support. Icing increases the load on the iron towers. Severe icing can cause the iron towers to collapse because they are unable to support these wires. If there is ice on the insulator strings on the iron towers, the only way is to pull the switch to stop the transmission line from transmitting electricity, thus causing large-scale power outages. Line icing constitutes a serious disaster. It is necessary to de-ice the line icing.

[0003] Artificial deicing is currently the main way to ensure the smooth operation of the power grid. The consequences of power outages and even power grid disconnection caused by icing are usually extremely serious, and the repair work is difficult and time-consuming. In order to ensure the reliability of the power system, improve the efficiency of deicing high-voltage transmission lines, reduce losses, and maintain the safety of workers, the development of safe and effective deicing machinery to replace human deicing of wires has good application prospects and practical significance.

[0004] After searching, there are applications of deicing using drones in the prior art, such as a transmission line drone thermal deicing device with publication number CN113555833A, which includes: an aircraft, a deicing control unit, a thermal deicing operation device, etc. However, when the prior art is used, a nozzle is used to spray flames on the ice layer on the surface of the transmission line to melt the ice layer on the surface of the transmission line, but the surface of the transmission line is easily burned when the flame is sprayed, which will reduce the service life of the transmission line.

[0005] In view of this, a drone blowing device is proposed to remove ice by breaking the ice layer, which can effectively reduce the damage to the cable during deicing. Summary of the invention

[0006] The purpose of the present invention is to provide a snow-clearing device for high-voltage cables. The device is driven by an unmanned aerial vehicle to move to the top of the cable so that the cable is stuck between two hammer plates. The hammer plates are driven by a driving device to reciprocate to break the ice on the cable. The crushed ice remaining on the cable is then blown away by a fan. De-icing is performed by breaking the ice layer, which is relatively simple. Flames are sprayed on the ice layer on the surface of the transmission line through a nozzle to melt the ice layer on the surface of the transmission line. This can effectively reduce damage to the cable during de-icing.

[0031] The use process of the high-voltage cable snow clearing device provided by the present invention is as follows: Technical principle: When in use, the drone driving device is moved to the top of the cable so that the cable is stuck in the position between the two hammer plates 6. The motor 17 drives the turntable 15 to rotate, thereby driving the connecting column 16 to rotate. When the connecting column 16 rotates, it drives the end of the third connecting rod 14 away from the guide rod 12 to rotate, so that the end of the third connecting rod 14 away from the connecting column 16 drives the guide rod 12 to reciprocate, and drives the hammer plate 6 to reciprocate. When the hammer plate 6 reciprocates, it hammers the ice layer on the surface of the cable to break the ice layer to de-ice. The fan 19 rotates to drive the airflow to blow to the cable, so that the crushed ice remaining on the cable is blown away from the cable. The heating tube 18 heats the air flowing through it to melt the ice layer that cannot be blown away, making the de-icing more thorough.
