Problems solved by technology

But this progress is too slow, and each person can beat only two or three kilometers a day; moreover, icebreakers often have numb hands and feet, backs and backs when working, and at the same time, they also risk great casualties such as broken lines and collapsed towers.

Embodiment Construction

[0029] from diagram 2-1 , Figure 2-2 It can be seen in the figure: the ground can transmit various signals such as advancing, reversing, and hitting through the remote control. After receiving the remote control signal, the high-altitude cable deicing device performs sorting and conversion, and then sends control commands to each unit to implement specific functions. The travel unit is composed of the main motor, transmission gear, travel wheel, cross-arm shaft, etc.; the deicing unit is composed of a 180° reciprocating motor and double pendulum hammers; the braking unit is composed of electromagnets, pressure springs, and brake pads; the working power supply It can be provided from the ground by mains electricity or gasoline and diesel generators, and it can also bring its own storage battery, eliminating the need for long pull wires.

[0030] Due to live deicing, this device works on a single phase, so its great feature is the cross-arm suspension type, and the balance pr...

Abstract

The invention relates to a split-phase electrified deicing device, belonging to mechanical and electrical integrated deicing equipment for a power transmission line. A control part consists of a transmitter, a receiver and a control circuit. A mechanical part comprises a traveling unit, a deicing unit and the like. In the traveling unit, a traveling wheel is a gear with a groove in the middle anda traveling motor drives the traveling wheel to rotate through a driving gear to move forwards or backwards along the power transmission line; and the deicing unit consists of a double-pendulum striking hammer which is installed on a motor and rotates forwards and backwards within 180 degrees together with the motor so as to strike to remove ice covering the power transmission line. In consideration of balance during movement, a dynamic balance device is also designed and consists of a liquid level switch, a set of gear transmission mechanism and a counterbalance. When a bottom plate tilts, the liquid switch is turned on, the motor is electrified to drive the gear transmission mechanism to rotate, the counterbalance is enabled to move on the bottom plate to change the gravity center of the device and therefore the bottom plate is kept in a balanced state. The split-phase electrified deicing device has the advantages of remote control, automatic traveling and automatic icebreaking.

Description

technical field [0001] The invention relates to a power transmission line deicing device, which is a transmission line deicing device that automatically advances, retreats, and vibrates in a remote control manner. Background technique [0002] Freezing disasters have become another black hand in power transmission. In the past, it was serious in the north. In recent years, it has also become a development trend in the south. In Hunan, Sichuan, Jiangsu and Zhejiang, downed poles, broken lines, power outages, and even personal casualties have occurred from time to time. The power system has been He paid a heavy price for it. So anti-icing and deicing has become one of the main security tasks in winter. [0003] Looking at the existing deicing methods, although automatic deicing devices such as frequency oscillation and line heating are installed in very few places, there are still certain technical problems, and there are millions of dollars in investment, fixed assembly loca...
