Description

Technical Field

[0001] The present application relates to the technical field of overhead cables, and in particular to a device for deicing the surface of overhead cables. Background Art

[0002] Overhead cables are overhead conductors equipped with an insulating layer and a protective outer sheath. They are a special type of cable manufactured using a production process similar to that of cross-linked cables. They are a new way of transmitting electricity between overhead conductors and underground cables. In the northern winter, ice is prone to form on the surface of overhead cables, which puts a load on the overhead cables and affects the power transmission of the overhead cables.

[0003] An overhead line deicing device mentioned in the existing Chinese public patent (authorization announcement number: CN219627340U) includes a mounting plate, a bottom plate, a power supply, a lifting mechanism, a lifting plate, a heating mechanism, a top plate, a controller, a roller, a first motor and a safety rope, wherein a bottom plate is welded to one side of the lower end of the mounting plate, wherein a power supply is fixed to the lower side of the bottom plate, and a lifting plate is installed on the upper side of the bottom plate through a lifting mechanism; a roller is installed on the upper side of the lifting plate, wherein a heating mechanism is installed on one side of the lifting plate; a top plate is welded to one side of the upper end of the mounting plate, wherein a controller is fixed to the upper side of the top plate; a first motor is installed on one side of the top plate; and one side of the top plate is connected to the bottom plate through a safety rope. The setting of the lifting mechanism and the heating mechanism of the utility model facilitates the fixing of the device to the overhead line, and can heat the outer side of the overhead line, thereby melting the ice layer on the outer side of the overhead line.

[0004] When the de-icing device is in use, it is used to de-ice the overhead cables. In the winter in the north, ice and snow are easy to cover the surface of the overhead cables, causing the overhead cables to bear a large weight, which is easy to affect the power transmission of the overhead cables. Therefore, the cables need to be de-iced. When de-icing, the above-mentioned de-icing device melts the ice on the surface of the cable through high temperature. However, in a low temperature environment, the melted ice and snow are easy to freeze again and cover the overhead cables, which is easy to cause incomplete ice and snow removal, affecting the use of the overhead cables.

[0024] 1. When the de-icing device moves, the elastic force of the spring causes the connecting column to move, and the movement of the connecting column drives the arc plate to move, and the arc plate drives the insulation plate to move, so that the cotton cloth conflicts with the cable. When the roller moves, the arc plate and the cotton cloth wipe the ice water on the cable. Part of the ice water flows down with the arc plate and flows out from the fixed inside, and part of the ice water is wiped off by the cotton cloth. When the heating tube is heated, the heat is transferred to the support frame, and the support frame conducts the heat to the arc plate. The insulation plate blocks the cotton cloth.

[0035] When the de-icing device is in use, the staff fixes the frame 1 and the fixing frame 2 to the cable through the fixing mechanism, so that the roller 3 contacts the cable, reduces the falling of the roller 3, facilitates the de-icing of the cable, and makes the frame 1 and the fixing frame 2 move more smoothly, and then starts the motor 4, the motor 4 drives the pulley to rotate, so that the roller 3 rotates, drives the frame 1 to move on the cable, and while moving, turns on the heating tube 8, the heating tube 8 heats the cable through the heating hole and the support frame 7, the temperature sensor 9 detects the heating temperature, and when the temperature is too high, it is fed back to the controller 6, the controller 6 controls the heating tube 8 to lower the temperature, melts the ice and snow on the cable surface and de-ices, and then reduces the adhesion of ice and water on the cable through the de-icing mechanism, reduces the secondary freezing of ice and water on the cable surface, and facilitates the use of the cable.

The limiting member includes two fixing bars 22 fixed to the lower end of the frame 1, and the fixing bars 22 are provided with limiting grooves 23 at positions corresponding to the fixing frame 2. Friction pads 21 are fixed on the rollers 3 and are distributed in an array, and the friction pads 21 are flexible rubber pads.

[0039] When the de-icing device is in use, the hydraulic telescopic rod 11 is started to drive the frame 1 and the fixed frame 2 to move away, and the bolts on the frame 1 are screwed to release the restriction on the support plate 13, and the support plate 13 is removed, driving the sliding rod 12 to separate from the support plate 2 14, so as to facilitate the installation of the frame 1, and make the sliding column slide on the support plate 2 14, so as to restrict the frame 1, and facilitate de-icing.

[0040] The implementation principle of the deicing device for the surface of an overhead cable in this embodiment is as follows: when the deicing device is in use, the hydraulic telescopic rod 11 is started to drive the frame 1 and the fixing frame 2 to move away from each other, and the bolts on the frame 1 are screwed to release the restriction on the support plate 13, and the support plate 13 is removed, and the sliding rod 12 is driven to separate from the support plate 2 14, so that the cable enters between the frame 1 and the fixing frame 2, and then the support plate 13 is reset, and the hydraulic telescopic rod 11 is started to drive the frame 1 to move, so that the frame 1 drives the fixing bar 22 to move into the restriction groove 23, and the frame 1 and the fixing frame 2 are restricted, and at the same time, the sliding column slides on the support plate 2 14 to restrict the frame 1, so that the roller 3 is close to the cable, which is convenient for the stable movement of the deicing device and reduces falling off;

[0041] Then start the motor 4, the motor 4 drives the pulley to rotate, so that the roller 3 rotates, the friction pad 21 increases the friction between the frame and the ice and snow, and drives the frame 1 to move on the cable. While moving, turn on the heating tube 8, the heating tube 8 heats the cable through the heating hole and the support frame 7, and the temperature sensor 9 detects the heating temperature. When the temperature is too high, it is fed back to the controller 6, and the controller 6 controls the heating tube 8 to lower the temperature to melt the ice and snow on the cable surface.

When the roller 3 moves, it drives the fixed column 15 to move, and the fixed column 15 drives the connecting column 17 to move, so that the arc plate 18 and the cotton cloth 19 wipe the ice water on the cable.

When the cotton cloth 19 needs to be replaced, the bolts on the arc plate 18 are turned to release the restriction on the arc plate 18, and the arc plate 18 is removed to facilitate the replacement of the cotton cloth 19, reduce the adhesion of ice water on the cable, and reduce the secondary freezing of ice water on the cable surface, so as to facilitate the use of the cable.
