Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable facility maintenance, in particular to a high-altitude cable deicing device and a high-altitude cable deicing method. BACKGROUND

[0002] The high-altitude cable, also known as overhead transmission line, mainly refers to overhead line, which is erected above the ground and is used to transmit electric energy by fixing the transmission conductor on the pole tower erected on the ground through insulators. The overhead transmission line is convenient to erect and maintain and has low cost, but is prone to failure due to weather and environment (such as strong wind, lightning, contamination, ice and snow, etc.). At present, the overhead transmission line is prone to form ice accretion on the cable in cold weather, which not only increases the burden of the cable and causes the cable to break, but also causes safety hazards when the ice accretion falls. In the prior art, when the ice accretion forms on the cable, the ice accretion on the cable is knocked off by manual work to realize the deicing of the cable, which not only has low deicing efficiency, but also causes the deicing personnel to be hit by the falling ice accretion, and has low safety.

After the ice falls onto the high-altitude cable de-icing device, it melts into water and is then discharged, avoiding direct falling ice that could cause injury to personnel and improving the safety of cable de-icing.

The motor drives the rotor blades of the propeller to rotate, generating lift. The spiral aircraft 17 can carry the base 11 to the high-altitude cable 20. The base 11 supports the first traveling mechanism 13, the first de-icer 15, the spiral aircraft 17, and the battery 18.

[0063] The base 11 has an ice-melting tank 111, a machine cavity 112, and drain holes 113. The ice-melting tank 111 is located above the machine cavity 112. A heating element 12 is provided between the ice-melting tank 111 and the machine cavity 112. Specifically, a partition 114 is provided between the ice-melting tank 111 and the machine cavity 112, separating them. The heating element 12 is located on the partition 114, which is a heat-conducting plate made of a good thermal conductor such as metal. The ice-melting tank 111 communicates with the outside of the base 11 through the drain holes 113. Multiple drain holes 113 are provided on both sides of the ice-melting tank 111. The partition 114 is inverted V-shaped, and its upper surface gradually rises along the direction away from the drain holes 113, which facilitates the drainage of water from the melted ice through the drain holes 113 on both sides.

[0064] The first walking mechanism 13 comprises a first bracket 1301 slidingly arranged on the base 11, a second bracket 1302 slidingly arranged on the base 11, a first roller 1303 rotatably arranged on the first bracket 1301, a second roller 1304 rotatably arranged on the second bracket 1302, a first driver 1305 in driving connection with the first roller 1303 and / or the second roller 1304, and a second driver in driving connection with the first bracket 1301 and the second bracket 1302 to move the first bracket 1301 and the second bracket 1302 towards or away from each other. The outer circumferential surface of the first roller 1303 and the outer circumferential surface of the second roller 1304 form a first cable clamping channel 1327, the first ice remover 15 is located above the ice melting groove 111 and on the extension path of the first cable clamping channel 1327, the first cable clamping channel 1327 extends along the extension direction of the cable 20, the outer circumferential surface of the first roller 1303 and the outer circumferential surface of the second roller 1304 are close to each other to form the first cable clamping channel 1327, and the cable 20 is clamped by the first cable clamping channel 1327. After the base 11 is brought to the high-voltage cable 20 by the helical aircraft 17, the first bracket 1301 and the second bracket 1302 are moved along the radial direction of the first roller 1303 or the radial direction of the second roller 1304 or the radial direction of the cable 20 under the driving of the second driver, so as to move the outer circumferential surface of the first roller 1303 and the outer circumferential surface of the second roller 1304 close to each other and clamp the cable 20 together, and then the helical aircraft 17 can stop flying, and the aerial cable 20 deicing device can be hung on the cable 20.

After the outer circumferential surface of the first roller 1303 and the outer circumferential surface of the second roller 1304 are close to each other and clamp the cable 20 together, the first driver 1305 is used to drive the first roller 1303 and the second roller 1304 to roll along the cable 20, so as to drive the entire aerial cable 20 deicing device to move along the cable 20.

[0065] The first de-icing device 15 is installed on the first support 1301 and / or the second support 1302. When the aerial cable 20 de-icing device moves along the cable 20, the cable 20 is de-iced by the first de-icing device 15. The first de-icing device 15 can de-ice the cable 20 by knocking or by heating. The ice on the cable 20 is separated from the cable 20 under the action of the first de-icing device 15, and then falls into the ice melting groove 111 below the first de-icing device 15. Then the ice in the ice melting groove 111 is melted into water by the heating sheet 12. Finally, the water is discharged through the drain hole 113.

[0066] The battery 18 is installed in the cavity 112. The heat generated by the battery 18 when it is powered can also be transmitted to the ice melting groove 111 through the partition 114 and the heating sheet 12, further improving the ice melting efficiency and saving energy.
