Description

TECHNICAL FIELD

[0002] Cables are the key carriers for transmitting energy and signals, and their external insulation and protective layers are crucial for ensuring long-term stable operation. When a cable is damaged, special equipment is usually used for repair. For example, patent CN120073563B discloses an overhead insulated cable surface repair device. The device generally includes a support frame, a driving mechanism (such as a bidirectional motor), a cleaning assembly, and a winding assembly. Its working principle is to remove dirt and loose materials from the damaged part of the cable by the cleaning assembly, and then tightly wrap and roll the insulation tape on the repaired part by the winding assembly to restore its insulation and protection functions. Compared with the earlier method (such as simply brushing waterproof insulation glue), the above-mentioned prior art has made significant progress, as it solves the problems of low efficiency and unstable quality of manual repair through mechanical automation.

[0003] However, the repair device still has design defects. The cleaning end (cleaning assembly) and the repair end (winding assembly) are arranged at the two ends of the moving wheels of the device. This layout causes two interrelated problems. First, it unnecessarily lengthens the cleaning path, and the device needs to move a longer distance to complete the entire process from cleaning to repairing, reducing the work efficiency. Second, and more importantly, when the device moves forward after cleaning, the moving wheels will roll over the cable segment that has just been cleaned. The dust, oil stains, and other pollutants on the cable surface may adhere to the moving wheels, causing secondary pollution to the cleaned cable surface to be repaired, affecting the integrity of the cleaning and the adhesion quality of the final repair layer, and posing a hidden danger to the long-term safe operation of the cable.

[0048] The buffer spring set 223 comprises a fixed sleeve 2231 fixedly connected to the inner wall of the hub support 221; a movable core shaft 2232 movably sleeved in the inner cavity of the fixed sleeve 2231 is provided, one end of the movable core shaft 2232 close to the hub support 221 is provided with a limiting plug handle as a mechanical limiting structure, the limiting plug handle ensures that the movable core shaft 2232 always remains inside the fixed sleeve 2231 when moving in the axial direction through the physical blocking effect, prevents it from completely separating, the surface of the movable core shaft 2232 is sleeved with a first spring 2233, the first spring 2233 acts as a buffer element, the two ends of the first spring 2233 are respectively abutted to the end face of the limiting plug handle and the inner edge of the port of the fixed sleeve 2231, an elastic pre-pressing structure is formed in the axial direction to maintain the dynamic cooperation relationship between the components, so that the movable core shaft 2232 can elastically stretch and contract along the inner cavity of the fixed sleeve 2231; the end portion of the movable core shaft 2232 is fixedly connected with the cleaning brush head 222;

[0049] In order to further improve the cleaning effect of the cleaning brush head 222 on the surface of the cable, the structure of the cleaning brush head 222 is further optimized, specifically, the cleaning brush head 222 comprises a liquid storage cavity 2221 fixedly connected with the movable core shaft 2232, the liquid storage cavity 2221 is filled with an adsorbing cotton layer 2223, the inner side of the liquid storage cavity 2221 is provided with a capillary oil guiding core 2222, the end portion of the capillary oil guiding core 2222 extends into the liquid storage cavity 2221 to contact the adsorbing cotton layer 2223, the outer side wall surface of the liquid storage cavity 2221 is provided with a microporous distribution plate 2224, the capillary oil guiding core 2222 can adsorb the cleaning agent permeated in the adsorbing cotton layer 2223 and uniformly coat on the surface of the cable, and the powerful decontamination effect is achieved;

[0050] In order to realize the automatic supply of oil contained in the adsorbing cotton layer 2223 during the cleaning process, the structure of the force applying head 62 is further optimized, specifically, the force applying head 62 comprises a liquid storage bin 621 connected to the bottom end of the guide column 61, a trigger type valve core 622 is arranged in the liquid storage bin 621, the trigger type valve core 622 comprises a valve piece 6221, one end of the valve piece 6221 is integrally formed with a taper head 6222, the other end of the valve piece 6221 is elastically connected in the liquid storage bin 621 through a second spring 6223, when the liquid storage bin 621 is attached to the cleaning brush head 222, the taper head 6222 in the trigger type valve core 622 will be subjected to the reaction force of the microporous distribution plate 2224 to compress the second spring 6223, that is, the taper head 6222 is pressed back into the liquid storage bin 621, so that the valve piece 6221 is separated from the liquid discharge port of the inner side wall of the liquid storage bin 621, at this time, the cleaning agent stored in the liquid storage bin 621 can be received by the microporous distribution plate 2224 and permeate to the adsorbing cotton layer 2223; on the contrary, when the jacking adjusting rod 6 releases the axial pressure on the cleaning brush head 222, the first spring 2233 in the buffer spring set 223 drives the cleaning brush head 222 to realize the radial reset movement through the elastic potential energy stored therein, and finally makes the brush head working surface form a preset safety distance with the surface of the conductive cable; (note: the repair agent cooling forming can use external intervention cooling device to shape or natural air drying), so that the equipment moves and positions to the next damaged point on the surface of the cable, and performs the same standardized repair operation as the previous processing procedure at the position;

[0051] The end of the taper head 6222 is provided with an inclined polytomy, when the outside of the liquid storage cavity 2221 contacts the taper face, the taper head 6222 is retracted through the extrusion force;

[0052] The cleaning agent can be selected as acetone; advantage: one of the strongest and most effective choices; acetone is a very strong organic solvent, which can quickly dissolve and remove oil stains, grease, silicone, flux residues and most organic pollutants on the surface of the cable; it volatilizes very quickly and does not leave residues.

[0053] Working principle of the application:

[0054] The opening of the main shell 21 and the cleaning wheel 22 side wall is radially sleeved on the cable periphery, so that the cable is coaxial with the main shell 21 and the cleaning wheel 22, and the cable is accurately dropped into the cleaning track of the cleaning wheel 22; then the first cylinder 8 is started, and the telescopic shaft drives the push-pull piece 4 to shrink to the center of the rack 1 through the connecting piece, so that the circumferentially distributed push-pull pieces 4 are simultaneously aggregated to the center, the included angle between the swing arm 3 and the push-pull piece 4 is continuously reduced, and the swing arm 3 is gradually overlapped with the bottom wall of the push-pull piece 4; in this process, the articulated rotary cleaning module 2 is pushed outward by the swing arm 3, so that the rotary cleaning module 2 linearly displaces along the cable surface, and the two groups of rotary cleaning modules 2 arranged symmetrically are separated to the two sides under the action of the thrust force, so that the cable surface is efficiently cleaned; at the same time, the piston push rod 52 is synchronously pulled to the cable during the aggregation process of the push-pull piece 4 to the center of the rack 1, so that the nozzle of the guide pipe 521 is gradually close to the side edge of the cable, and the valve plate 522 compresses the repair agent in the liquid cavity of the transformer box body 51 at this time; when the guide pipe 521 reaches the preset spraying position, the cleaning wheel 22 has completed the cleaning work of the current section to form a process preposition, and at this time the nozzle adjuster 53 is activated to make the repair agent in the liquid cavity sprayed to the cable surface to be repaired through the flow guide hole 523, the valve plate 522 and the unblocked guide pipe 521, and the spraying angle can be dynamically adjusted by operating the extensible section of the guide pipe 521, so that the blind area of spraying is effectively eliminated; the design not only achieves the cleaning preposition of the cable, but also provides pressure kinetic energy for the delivery of the repair agent, so that the cable cleaning and repair processing are efficiently cooperated; after the work is completed, the equipment is separated from the cable along the reverse motion track of the assembly and is reset to the initial position, and at this time the liquid cavity of the transformer box body 51 automatically forms a negative pressure storage state in the mechanical reset process, which provides negative pressure adsorption power conditions for the autonomous repair system of the repair agent when the subsequent negative pressure supply valve 54 starts to work, so that the closed loop working cycle of the equipment can be continuously worked;

[0055] In the above working process, the driving force for the circumferential rotation of the cleaning wheel 22 is provided by the power mechanism 23, specifically: the output shaft of the motor drives the transmission gear 231 rigidly connected thereto to rotate, and through the synchronous belt 233, the linkage pulley 232 is driven to make the two transmission gears 231 rotate synchronously and in the same direction, so that at least one transmission gear 231 can transmit power to the hub support 221 in the cleaning wheel 22, and drive the entire cleaning wheel 22 to complete the circumferential cleaning action along the cable surface;

[0056] In the above operation process, in the process of adjusting the pressure of the cleaning wheel 22 on the cable, the telescopic shaft of the second cylinder 9 drives the jacking adjusting rod 6 to move towards the center of the main shell 21, and the force head 62 then exerts pressure on the outside of the cleaning brush head 222. This force gradually drives the cleaning brush head 222 away from the fixed sleeve 2231 by pulling the movable mandrel 2232 and compressing the first spring 2233, thereby enhancing the adhesion of the cleaning brush head 222 to the surface of the cable, expanding the contact area of the capillary oil guide core 2222, and improving the cleaning efficiency. At the same time, when the liquid storage bin 621 is attached to the cleaning brush head 222, the conical head 6222 in the trigger valve core 622 will be subjected to the reaction force of the micro-hole distribution plate 2224 to compress the second spring 6223, i.e. to press the conical head 6222 back into the liquid storage bin 621, causing the valve plate 6221 to be separated from the liquid outlet of the inner side wall of the liquid storage bin 621. At this time, the cleaning agent stored in the liquid storage bin 621 can be accepted by the micro-hole distribution plate 2224 and permeate to the adsorbing cotton layer 2223, and finally be uniformly coated on the surface of the cable by the capillary oil guide core 2222 after being adsorbed, realizing the dual synergy of precise release of cleaning agent and mechanical decontamination, and significantly enhancing the cleaning effect of the cable.

[0057] The above is only one preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application; according to the technical plan and improvement idea of the present application, equivalent substitution or modification is carried out, which should be included in the protection of the present application.
