The invention discloses a deicing robot control system integrating mechanical deicing and thermal deicing, relates to the technical field of protection equipment for overhead power transmission cables, and solves the problem of high temperature generated by the existing thermal deicing mechanism due to continuous heat generation. The problem of internal damage includes the communication module, the conversion controller installed on the deicing robot, the battery, and the stepper motor that drives the thermal deicing mechanism for deicing. The thermal deicing mechanism is equipped with a U-shaped heating plate and a U-shaped The relay electrically connected to the U-shaped heating plate and the temperature sensor installed on the U-shaped heating plate, the U-shaped heating plate is arranged circumferentially around the transmission line, and the thermal deicing mechanism controls the closing of the relay by the conversion controller to provide heat for the U-shaped heating plate , by implementing the technical solution, the temperature of the U-shaped heating plate arranged circumferentially around the transmission line can be controlled within the set temperature range, and the thermal deicing mechanism can be prevented from causing damage to the interior of the transmission line due to continuous heat generation.

Description

technical field [0001] The invention relates to the technical field of protection equipment for overhead power transmission cables, and more particularly relates to a control system for a deicing robot integrating mechanical deicing and thermal deicing. Background technique [0002] Icing of transmission lines in winter is one of the natural disasters of the power system. Due to the increased ice load on the conductors, it will cause certain mechanical damage to the conductors, iron towers and fittings. When the ice is severe, the wires will be disconnected, the towers will be inverted, the conductors will dance and flashover and trip, resulting in large-scale power outages. Because the accident occurred in the severe winter season, the mountain was blocked by heavy snow or the road was icy, which made the emergency repair conditions very difficult, resulting in a long-term power outage, which seriously threatened the safe and stable operation of the power grid and the relia...

AI Technical Summary

Problems solved by technology

However, this technical solution still has the following deficiencies: 1. Only the mechanical deicing method of percussion and vibration is used, and its effect on icing with strong binding force and thick ice layer such as rain rime and mixed rime is limited, and the deicing effect Not good; 2. The thermal deicing mechanism fixed on the transmission line is easy to cause damage to the interior of the transmission line due to the continuous heating of the thermal deicing mechanism; 3. General mechanical deicing cannot adapt to the icing of overhead lines of different diameters. The cutter head of the deicing mechanism cannot adjust the distance or can only be disassembled and adjusted at the construction site, which is complicated to operate
