[0024] This application provides a repair device for cable joint 5, such as Figure 1 and Figure 2As shown, the assembly includes a drive component 1, a scraper component 2, and a positioning component 3. The scraper component 2 is directly or indirectly connected to the drive component 1, and the scraper assembly is used to contact the part of the cable connector 5 to be repaired. The positioning component 3 is connected to the scraper component 2 and / or the drive component 1, and the positioning component 3 is used to abut against the cable connector 5.

[0025] The repair device provided in this application includes a driving component 1, a scraping component 2, and a positioning component 3. The positioning component 3 can be connected to the driving end of the driving component 1, or it can be connected to the non-driving end of the driving component 1. That is, the positioning component 3 can be a structure that moves synchronously with the driving end, or it can be a structure that does not move with the driving end. The positioning component 3 is used to assist the scraping component 2 in positioning and installation, ensuring that the scraping component 2 can contact the cable connector 5, so as to scrape and cut off the damaged parts on the surface of the cable connector 5.

[0026] The driving component 1 provides driving force, enabling the scraping component 2 to rotate relative to the cable connector 5. Through the contact relationship between the scraping component 2 and the cable connector 5, the burnt and damaged insulation on the surface of the cable connector 5 is scraped off. Specifically, the driving component 1 is an electrically driven component, specifically a drive motor.

[0027] Specifically, the scraper 2 can be made of a high-hardness, wear-resistant alloy blade. The blade is sharp and can accurately scrape off the insulating material from the arc-burned area.

[0028] The repair device provided in this application can quickly repair the burned parts of the cable joint 5, restore insulation performance, reduce the risk of electric arc, extend the service life of the cable joint 5, reduce the number of overall replacements, save maintenance costs, facilitate construction, reduce labor intensity, improve maintenance efficiency, and ensure stable and reliable performance of the insulation layer after repair, which can meet the needs of long-term operation. It can be widely applied to cable joints 5 of different specifications and has good adaptability and versatility.

[0029] In one possible implementation, such as Figure 1 and Figure 2 As shown, the positioning component 3 includes a positioning cover, which has a connecting end and an open end. The connecting end is connected to the driving component 1, and the open end abuts against the cable connector 5. The scraping component 2 is disposed on the inner wall of the positioning cover, and the driving component 1 drives the scraping component 2 to move synchronously through the positioning cover.

[0030] In this embodiment, the positioning member 3 includes a positioning cover, one side of which is an open end and the other side of which is a connecting end. The open end and the connecting end are opposite ends. For example, the open end is located at the bottom of the positioning cover and the connecting end is located at the top of the positioning cover.

[0031] When the positioning cover is installed on the cable connector 5, the cable connector 5 will pass through the opening end of the positioning cover and enter the interior of the positioning cover. When it is in place, the opening end of the positioning cover will abut against the base of the cable connector 5. The scraper 2 is located on the inner wall of the positioning cover. The drive unit 1 can indirectly drive the scraper 2 to rotate by driving the positioning cover, so that the scraper 2 can repair the surface of the cable connector 5.

[0032] It should be noted that the shape of the positioning cover is adapted to the shape of the cable connector 5. When the positioning cover is placed on the cable connector 5, the scraper 2 located inside the positioning cover can make good contact with the cable connector 5, ensuring that the damaged area of ​​the cable connector 5 can be effectively scraped off.

[0033] In one possible implementation, such as Figure 1 and Figure 2 As shown, the positioning cover includes a cover body 31 and a limiting connecting block 32. The bottom of the cover body 31 has an open end, and the scraper 2 is provided on the inner wall of the cover body 31. The limiting connecting block 32 is provided on the side of the cover body 31 away from the open end. The limiting connecting block 32 forms a connecting end and cooperates with the limiting groove of the driving member 1.

[0034] In this embodiment, the positioning cover includes a cover body 31 and a limiting connecting block 32. The bottom of the cover body 31 is provided with an open end, and the scraper 2 is provided on the inner wall of the cover body 31. When the cover body 31 rotates, the scraper 2 will rotate synchronously with the cover body 31.

[0035] The limiting connection block 32 is located at the top of the cover 31. The driving component 1 is effectively connected to the cover 31 through the limiting connection block 32, thereby ensuring that the driving component 1 drives the cover 31 to move synchronously.

[0036] Specifically, the limiting connection block 32 is a polygon, for example, a rectangular block.

[0037] In one possible implementation, such as Figure 1 and Figure 2 As shown, the positioning cover also includes a connecting rod 33, and the positioning cover is detachably connected to the drive component 1 through the connecting rod 33.

[0038] In this embodiment, considering the small installation space of the cable connector 5, the operable range of the positioning cover can be extended by providing a detachable connecting rod 33 for the positioning cover. One end of the connecting rod 33 is connected to the cover body 31, and the other end of the connecting rod 33 is connected to the drive component 1.

[0039] Specifically, one end of the connecting rod 33 is provided with a groove, and the limiting connecting block 32 on the cover 31 can be embedded in the groove of the connecting rod 33. The other end of the connecting rod 33 can be embedded in the groove of the driving component 1, thereby realizing the effective connection between the driving component 1 and the positioning component 3 and the scraping component 2 through the connecting rod 33.

[0040] In one possible implementation, such as Figure 1 and Figure 2 As shown, the scraper 2 includes multiple detachable metal brushes 21, which enclose a working cavity to accommodate the cable connector 5.

[0041] In this embodiment, the scraping component 2 includes multiple metal brushes 21, which are detachably mounted on the inner wall of the cover 31. When the metal brushes 21 are severely worn, they cannot ensure effective contact with the cable connector 5 and it is difficult to achieve the scraping function. In this case, the metal brushes 21 can be removed from the opening end of the cover 31 for replacement, effectively ensuring the repair function of the scraping component 2 for the cable connector 5.

[0042] Among them, the metal brush 21 can not only perform scraping and repair functions, but also has a certain degree of deformation, making it suitable for cable joints 5 with different degrees of damage.

[0043] In one possible implementation, the metal brush 21 is a steel brush.

[0044] In one possible implementation, the inner wall of the positioning cover is provided with mounting portions distributed along the height direction of the positioning cover, and the metal brush 21 is provided with assembly portions that cooperate with the mounting portions.

[0045] In this embodiment, the mounting part is disposed on the inner wall of the positioning cover along the height direction of the positioning cover. For example, the mounting part is a protrusion that extends along the height direction of the positioning cover. Correspondingly, the metal brush 21 includes a base plate and bristles. The base plate is provided with a mating groove that mates with the protrusion. The metal brush 21 can be connected to the positioning cover by inserting the bristles into the protrusion, making disassembly convenient.

[0046] Meanwhile, since the metal brush 21 is mounted on the positioning cover along the height direction of the positioning cover, and the positioning cover and the metal brush 21 will rotate under the drive of the drive component 1, and the two are in different directions, the connection between the metal brush 21 and the positioning cover is reliable and durable and will not easily fall off.

[0047] In one possible implementation, such as Figure 1 As shown, the repair device also includes an insulating sleeve 4, which is fitted onto the cable joint 5.

[0048] In this embodiment, after the cable joint 5 is scraped by the scraper 2, a new insulating sleeve 4 is then fitted onto the cable joint 5. The insulating sleeve 4 can provide stable insulation protection, making the insulation performance of the repaired cable joint 5 stable and reliable, and meeting the long-term operation requirements.

[0049] In one possible implementation, the insulating sleeve 4 comprises a rubber sleeve. The rubber sleeve has self-adaptive capabilities, allowing for a better and tighter wrapping of the cable joint 5 after it has been scraped.

[0050] In one possible implementation, the insulating sleeve 4 is provided with a positioning part for engaging with the cable connector 5.

[0051] In this embodiment, the insulating sleeve 4 is also provided with a positioning part, which can be used to cooperate with the cable connector 5 to ensure that the insulating sleeve 4 is installed in place. For example, the positioning part may include a snap-fit ​​structure, a magnetic attraction structure, etc.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them.
