Description

Automatic-travelling beating type power transmission line deicing device and use method thereof

Technical Field

The invention relates to the technical field of power transmission line deicing, in particular to an automatic-travelling beating type power transmission line deicing device and a using method thereof.

Background

Icing is a natural disaster with extremely strong destructiveness, and brings great influence to industrial and agricultural production and people's life. Seriously affecting the service performance and operation safety of the circuit. The ice and snow covering can increase the load of the transmission line, and line disconnection and pole tower tilting collapse can occur when serious, so that the development of a line deicing technology is beneficial to reducing faults, damage and power failure and improving the safety level of the transmission line.

The existing line deicing technology mainly comprises mechanical deicing, heating deicing, chemical deicing and other modes, wherein the mechanical deicing can directly remove the coverage of the line surface through a scraping shovel or a manual beating device, the mode has the characteristics of high efficiency and low cost, but the existing deicing device is only applicable to deicing of a line with a certain line diameter, the use occasion of deicing equipment is limited, and meanwhile, the simple and rough mechanical deicing often causes damage to the line surface; the heating deicing mode has high efficiency and less damage, but also has higher energy consumption and cost; chemical deicing mainly achieves the deicing effect by spraying an ice melting agent or a hydrophobic material on the surface of a line, but the influence of the material on the environment restricts the development of chemical deicing.

For example, CN110429545a discloses an automatic deicing device in a power transmission line and a working method thereof, wherein the device comprises an electric heating plate, a bottom plate, a first mechanical arm, a second mechanical arm, a third mechanical arm, an icing sensor, a power supply device and a control device. The electric heating plate is provided with a water leakage hole towards one side of the power transmission line, the front end of the bottom plate is provided with a control device and a first mechanical arm, the middle part of the bottom plate is provided with a second mechanical arm and an icing sensor, the icing sensor is arranged at the front end of the second mechanical arm, the rear end of the bottom plate is provided with a third mechanical arm and a power supply device, and the control device is connected with the power supply device, the electric heating plate, the first mechanical arm, the second mechanical arm, the third mechanical arm and the icing sensor; the deicing device realizes deicing of the power transmission line, can also cross obstacles, and can reduce damage to the power transmission line by using electricity for deicing, but has high energy consumption and high cost, and the deicing device completely depends on heating for deicing, has low efficiency, and is easy to bring secondary deep icing after deicing.

For example, CN117060316a discloses an automatic removing device for ice coating on an overhead high-voltage transmission line, which comprises a driving unit for moving on the transmission line, wherein a first deicing unit is installed at the right end of the driving unit through an auxiliary plate, and a plurality of second deicing units distributed in a semicircular shape are connected to the first deicing unit. According to the existing method, ice cubes can be promoted to melt through the movable electric heating pipe, the ice cubes are broken through swinging of the ice breaking rod, so that ice coating on the surface of the power transmission line is removed, but the adopted electric heating pipe can only heat the ice coating from one place, and the ice coating melting effect is not ideal. The adopted first deicing unit is matched with the second deicing unit, so that multidirectional local melting treatment can be firstly carried out on the ice covered in the ring shape, and then the ice is removed from the surface of the power transmission line in a mode of knocking at a plurality of angles, so that the effect of removing the ice covered on the surface of the power transmission line is improved; however, the device is complex and heavy in structure, and the device is used for knocking operation from the side face of the cable, so that shaking impact force brought to the cable is large, safety is poor, no cleaning mechanism is provided, and accumulated water after ice melting is easily brought to ice deeply again.
