Deicing robot for double spacing-variable electric wires

Abstract

The invention discloses a deicing robot for double spacing-variable electric wires. The deicing robot comprises a bottom plate, a front guide walking mechanism, a first ice rolling mechanism, a second ice rolling mechanism, a ratchet wheel pallet vibration mechanism, a back guide walking mechanism and a spacing regulation mechanism, wherein the front guide walking mechanism mainly comprises a first motor, a cog belt, a front walking wheel bracket, a driving wheel and a front driven wheel; the first ice rolling mechanism mainly comprises a second motor, a gear I, a first ice rolling wheel, a first ice rolling shaft and a gear II; the second ice rolling mechanism mainly comprises a third motor, a gear III, a second ice rolling shaft and a second ice rolling wheel; the ratchet wheel pallet vibration mechanism mainly comprises a fourth motor, a vibration pallet, a reset spring and a ratchet wheel; and the spacing regulation mechanism mainly comprises a handle, a lead screw shaft, a chain wheel, a lead screw base and a chain. The deicing robot can deice two electric wires of different spacings as well as can shake off the crushed ice through vibration by adopting the ratchet wheel pallet vibration mechanism; and meanwhile, the deicing robot is easy to control, relatively low in cost and relatively high in practicability.

Description

technical field [0001] The invention relates to the technical field of deicing and snow removal of high-voltage transmission lines, in particular to a double-connected variable-pitch electric wire deicing robot. Background technique [0002] Most of the power resources currently used in my country are thermal power generation, which makes the domestic power transmission network area very large. High-altitude high-voltage power transmission lines can be seen everywhere in the wild, and large-scale rain, snow and freezing weather will occur in winter in northern my country , the temperature in some areas even reaches minus tens of degrees, such continuous severe cold weather will make the wires covered with ice and snow, the long-term ice coating on the surface of the transmission line and the uneven ice coating on the wires will cause the wires to dance in the air, which will cause the wires to trip , power supply interruption and other phenomena, in severe cases, it will lead ...

Chinese Patent No. 201420286878.1 discloses a deicing device for electric wires. The device melts the ice on the electric wires through a flame spraying device, and at the same time uses a deicing knife to remove residual ice. When covering ice, it takes a lot of time and the efficiency is low, and using fire to melt the ice layer will cause certain damage to the wire cortex; Chinese patent No. 201420808698.5 discloses a power transmission line deicing tool, which uses The ultrasonic principle is used for deicing, the ultrasonic generating device is fixed on the body, and the ice layer on the wire is removed with the tool head of the ultrasonic cutter. This method can reduce the damage to the wire, but the cost of deicing by ultrasonic is not only high but also The control is difficult and the practicability is poor. In addition, the device can only de-ice a single wire, and cannot de-ice two wires at the same time; Chinese patent No. 201520288230.2 discloses a power line de-icing device. The device uses two milling cutters for deicing and a percussion hammer connected to the motor to vibrate and remove residual ice, so as to achieve the effect of deicing the wires, but the sharper milling cutters will cause more or less damage to the cortex of the wires. In addition, When a percussion hammer is used to knock the residual ice, the percussion force of the percussion hammer is difficult to control, and there will be a phenomenon that the wires dance in the air. In addition, although the device can perform deicing operations on two wires at the same time, its The spacing cannot be adjusted, and it cannot be used for deicing operations on wires with different spacings; US Patent No. US20150059114A1 discloses a high-voltage transmission line deicing device. A vibrating device is used to achieve the purpose of deicing and snowing the wires. This device has a more obvious effect on removing snow, but the removal effect is relatively poor for the ice layer attached to the wires; in addition, the method of manually removing ice from wires is not only Low efficiency and very poor practicability in deep mountain and ravine environments
