Description

Technical Field

[0001] The utility model belongs to the technical field of power cables, and particularly relates to an ice remover for power cables. Background Art

[0002] A power cable is a cable used for transmitting and distributing electric energy. It mainly consists of a conductor, an insulating layer, a sheath, etc. The conductor usually adopts metal materials such as copper or aluminum, which has good electrical conductivity and is responsible for transmitting current. The insulating layer isolates the conductor from the outside world to ensure the safe transmission of current. Common insulating materials include cross-linked polyethylene, polyvinyl chloride, etc. The sheath plays a protective role for the entire cable, preventing mechanical damage, chemical erosion, etc. Power cables are widely used in power systems, including transmission lines from power plants to substations, connections within substations, distribution lines in urban power grids, etc., and are an essential and important part of modern power supply.

[0003] For example, the "ice remover for power cables" disclosed in the application number "202223004918.2" is also an increasingly mature technology. When ice removal is required for a power cable, the knocking mechanism cooperates with the traveling mechanism, so that the entire cable can be continuously knocked to remove ice, improving the ice removal efficiency and quality of the ice remover for the cable, and further improving the service life of the cable.

[0004] When the disclosed ice remover for power cables removes ice, the ice on the cable is cleaned by pushing and hitting the cable up and down by the ice removal mechanism. However, during the ice removal operation, the pushing amplitude will cause bending and stretching of the cable, and such multiple excessive stretches will cause inevitable damage to the cable. Therefore, it needs to be improved. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an ice remover for power cables, aiming to solve the problem in the prior art that the pushing amplitude during ice removal will cause bending and stretching of the cable, and such multiple excessive stretches will cause inevitable damage to the cable, so it needs to be improved.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An ice remover for power cables, including a cable, a traveling mechanism is movably installed on the cable, an ice removal mechanism is installed on one side of the traveling mechanism, and a limit cover is arranged between the two traveling mechanisms;

[0007] Side plates are respectively welded on both sides of the limit cover, a movable rod is installed on the side plate, the bottom of the movable rod is inserted into the inside of a sleeve rod, the bottom of the sleeve rod is fixedly installed on the surface of an installation strip, and the installation strip is installed on the surface of the ice removal mechanism through bolts.

[0008] In order to slow down the upward movement of the cable when the de-icing mechanism pushes the cable upward and prevent the cable from moving upward too much, as an optimization of the power cable de-icing machine of the present utility model, a backing plate is fixedly bonded to the bottom of the limit cover. The side of the backing plate is of a semi-circular structure, and the backing plate is made of flexible insulating rubber material.

[0009] In order to complete the docking between the side plate and the movable rod, as an optimization of the power cable de-icing machine of the present utility model, a group of through holes are symmetrically arranged on the side plate, and the inner diameter size of the through holes is adapted to the diameter size of the end of the movable rod.

[0010] In order to prevent the movable rod from detaching from the side plate, as an optimization of the power cable de-icing machine of the present utility model, a nut is screwed onto the end of the movable rod, and a fixed disk is fixedly welded at a position of the movable rod close to its end.

[0011] In order to prevent the side plate from sliding down excessively on the movable rod, as an optimization of the power cable de-icing machine of the present utility model, the upper surface of the fixed disk is in movable contact with the bottom of the side plate, and the bottom of the nut presses against the upper surface of the side plate after being docked with the movable rod.

[0012] In order to enable the movable rod to perform up and down telescoping, as an optimization of the power cable de-icing machine of the present utility model, a disk is fixedly installed at one end of the movable rod located inside the sleeve rod. A spring is connected to the bottom of the disk, and the other end of the spring is connected to the longitudinal inner wall of the sleeve rod.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

In this way, the pulling force when the cable is lifted can be reduced, the damage to the cable during de-icing can be reduced, and a protection function for the cable is achieved.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model provides the following technical solutions: A power cable de-icing machine includes a cable 1, a traveling mechanism 2 is movably installed on the cable 1, a de-icing mechanism 3 is installed on one side of the traveling mechanism 2, and a limit cover 4 is arranged between the two traveling mechanisms 2;

[0023] The two traveling mechanisms 2 are installed on the cable 1. During use, the de-icing mechanism 3 will impact the ice on the cable 1, thereby achieving the function of de-icing.

[0024] Side plates 5 are respectively welded on both sides of the limit cover 4. A movable rod 6 is installed on the side plates 5. The bottom of the movable rod 6 is inserted into the inside of the sleeve rod 7. The bottom of the sleeve rod 7 is fixedly installed on the surface of the mounting strip 8. The mounting strip 8 is installed on the surface of the de-icing mechanism 3 through bolts.

[0025] Preferably: A backing plate 401 is fixedly adhered to the bottom of the limit cover 4. The side surface of the backing plate 401 is a semi-circular structure. The backing plate 401 is made of flexible insulating rubber material.

[0026] During specific use, when the cable 1 moves upward to the maximum range under the thrust, one side of the cable 1 will be pressed against the backing plate 401. At this time, the soft backing plate 401 will reduce the extrusion force on the cable 1 during extrusion, thereby improving the protection effect on the cable 1.

[0027] Preferably, a set of through holes 501 are symmetrically formed in the side plate 5. The inner diameter of the through holes 501 is adapted to the diameter of the end of the movable rod 6, and a threaded structure is provided at the top of the movable rod 6. A nut 601 is screwed onto the end of the movable rod 6, and a fixed disk 602 is fixedly welded to the position of the movable rod 6 near its end. The upper surface of the fixed disk 602 is in movable contact with the bottom of the side plate 5, and the bottom of the nut 601 presses against the upper surface of the side plate 5 after being butted against the movable rod 6.

[0028] During specific use, after the through holes 501 on the side plate 5 are butted against the ends of the movable rods 6, the side plate 5 will move downward under its own gravity. When the bottom of the side plate 5 contacts the surface of the fixed disk 602, the side plate 5 will stop further downward movement. Then, the nut 601 is tightened on the top of the movable rod 6, so that the side plate 5 can be installed on the movable rod 6.

[0029] Preferably, a disk 9 is fixedly installed at one end of the movable rod 6 located inside the sleeve rod 7. A spring 901 is fixedly connected to the bottom of the disk 9, and the other end of the spring 901 is connected to the longitudinal inner wall of the sleeve rod 7.

[0030] During specific use, when the limit cover 4 is impacted by the cable 1, it will drive the movable rod 6 to move upward. When the movable rod 6 moves upward, it will drive the spring 901 to move upward through the disk 9. At this time, the spring 901 will weaken the pulling force when the limit cover 4 moves upward under its own elastic force, and thus the impact force when the de-icing mechanism 3 pushes the cable 1 upward can be further reduced through this structure.

[0031] Working principle: When the de-icing mechanism 3 performs de-icing operations on the cable 1 through impact, the cable 1 will deform and bend upward at this time. When the cable 1 bends to the maximum stroke, the top of the cable 1 will press against the bottom of the limit cover 4;

[0032] At this time, the limit cover 4 will drive the movable rod 6 to move upward through the side plate 5. At this time, the movable rod 6 will be counteracted by the reverse force of the spring 901 to offset part of the upward pulling force, so that the upward movement amplitude of the cable 1 can be controlled, and thus the damage caused to the cable 1 by excessive full amplitude can be reduced.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
