The invention provides an equipment ice melting method, device and system based on the microwave technology. The method obtains ice layer information of ice frozen equipment and determines the microwave frequency of ice melting according to the ice layer information of the ice frozen equipment and then determines an ice melting mode according to the ice layer information of the ice frozen equipment and the microwave frequency of the ice melting. The system comprises a sensing unit used to acquire the ice layer information of the ice frozen equipment; a microwave generating unit used to smoothly output high-power microwaves; a steam generating unit used to generate steam by radiation heating of a monopole oscillator antenna; ice melting unit for performing ice melting; and a control unit for performing the ice melting according to the method. The invention is suitable deicing of non-power-transmission lines, realizes jointly implementation of four types of ice-melting modes such as microwave radiation ice melting, microwave electrode ice cutting, microwave steam ice melting and microwave steam ice cutting so as to achieve safe, fast and highly-efficient electrical equipment deicing.

The invention provides a four-cable synchronous deicing robot and a deicing method. The four-cable synchronous deicing robot comprises a cross beam, two swing arms, a movable table, four rotor helicopters, four cone pulley sets, a lead screw motor, two guide wheels and four cables, wherein the cone pulley set comprises a main cone pulley, an auxiliary cone pulley and a motor; a motor shaft is in key connection with the main bevel wheel; gears of the main cone wheel and the auxiliary cone wheel are in engaged transmission; and the cross beam and the swing arms are fixedly connected with the motor and are rotationally connected with the main cone pulley and the auxiliary cone pulley; the cross beam is rotationally connected with the swing arms; the movable table is fixedly connected with thelead screw motor and supports of four rotor helicopters, and is connected with two guide wheel through shafts; arc-shaped grooves of the swing arms are in rolling contact with the guide wheels; and alead screw of the lead screw motor is spirally connected with a threaded hole of the cross beam. During deicing, the two cone pulley sets of the cross beam clamp two cables, and the movable table pushes the swing arms through the guide wheels to drive the cone pulley sets to clamp the other two cables to walk for deicing; and when deicing is finished, the lead screw motor drives the swing arms torotate reversely, so that the cone pulley sets are separated from the cables, and the rotor helicopters carry the robot to fly to the ground or a cable to be deiced.

The invention belongs to the technical field of unmanned aerial vehicles, and discloses a high-altitude flight antifreezing system of an unmanned aerial vehicle. The system comprises heating structures, power supply batteries, a vehicle-mounted controller, a wireless transreceiver module and a ground remote control terminal, wherein the heating structures are connected with the power supply batteries through control switches to obtain electric energy to generate heat, and are distributed on windward sides of wings and empennages of the unmanned aerial vehicle; the control switches are connected with the vehicle-mounted controller to control the power supply of the heating structures; and the vehicle-mounted controller communicates with the ground terminal control terminal through the wireless transreceiver module. The system is provided with the heating structures on the wings and the empennages of the unmanned aerial vehicle to deal with the problem of freezing of the windward surfaces in the high-altitude flight so as to prevent the freezing from influencing the aerodynamic configuration and causing signal transmission distortion; and meanwhile, a remote control communication mechanism is established to realize flexible deicing and antifreezing control and prevent freezing.
