[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model provides a power cable reinforcement device, such as... Figure 1-4 As shown, the power cable reinforcement device includes: two reinforcement shells 1 for securing the power cable connection; an insulating sleeve 2 disposed inside the reinforcement shell 1; sealing sleeves 3 disposed at both ends of the reinforcement shell 1; a pressure sleeve 4 disposed on the sealing sleeve 3; a rack 6 symmetrically fixed on the pressure sleeve 4; a guide sleeve 5 fixed on the reinforcement shell 1; and a limiting mechanism disposed on the reinforcement shell 1 for limiting the rack 6.

[0021] In this embodiment, before installation, when connecting two cables, the compression sleeve 4 and the sealing sleeve 3 are first put on the two cables in sequence, and the insulating sleeve 2 is put on one of the cables so that it can be put on the connection point later. After the cables are connected, the insulating sleeve 2 is moved to the connection point, the two reinforcing shells 1 are fastened and secured at the connection point, the sealing sleeve 3 is attached to both ends of the reinforcing shell 1, the compression sleeve 4 is put on the cable and pushed to the sealing sleeve 3, the rack 6 is inserted into the guide sleeve 5, and the rack 6 is fixed by the limiting mechanism so that the compression sleeve 4 presses the sealing sleeve 3 tightly.

[0022] The insulating sleeve 2 enhances the insulation of the connection, the two reinforced shells 1 improve the overall strength and rigidity, the sealing sleeve 3 and the pressure sleeve 4 work together to enhance the sealing performance and reduce the influence of external factors, and the limiting mechanism fixes the rack 6 to ensure structural stability. This device can enhance the impact resistance of the cable intermediate joint, reduce the risk of damage caused by external impact, reduce discharge and safety accidents, extend the service life of the joint, and improve the safety of power transmission.

[0023] In a further preferred embodiment of the present invention, the limiting mechanism includes: a threaded tube 7 fixed on the reinforcing shell 1; a threaded post 8 threadedly assembled on the threaded tube 7; and a limiting plate 9 sleeved on the threaded post 8. A toothed block 11 is fixed on the limiting plate 9 by a connecting block 10, and the toothed block 11 can limit the movement of the rack 6.

[0024] In this embodiment, after the rack 6 passes through the guide sleeve 5, the threaded column 8 is rotated to move it inside the threaded tube 7, the limiting plate 9 descends, and the toothed block 11 engages with the rack 6 to complete the fixing of the rack 6.

[0025] The threaded tube 7 provides support and a movement path for the threaded column 8. The threaded column 8 limits the position of the limiting plate 9. The toothed block 11 cooperates with the rack 6 to stably restrict the movement of the rack 6. The connecting block 10 fixes the toothed block 11 and the limiting plate 9. This limiting mechanism can more stably limit the rack 6, enhance the pressure stability of the pressure sleeve 4 on the sealing sleeve 3, improve the overall robustness of the reinforcement device, and further reduce the possibility of damage to the cable intermediate joint due to external impact.

[0026] In a further preferred embodiment of the present invention, an outer shell 13 is provided outside the reinforced shell 1, and a connecting plate 15 is fixed at the connection of the outer shell 13. The connecting plate 15 is provided with bolts 16 for limiting the position.

[0027] In this embodiment, the outer shell 13 is fitted over the reinforcing shell 1, the connecting plate 15 at the connection of the outer shell 13 is aligned, and the bolt 16 is installed on the connecting plate 15 and tightened to fix the outer shell 13. The outer shell 13 can form external protection for the reinforcing shell 1, the connecting plate 15 provides support for the connection of the outer shell 13, and the bolt 16 can fix the connecting plate 15, thereby enhancing the stability of the connection of the outer shell 13.

[0028] In a further preferred embodiment of the present invention, a knob 12 is fixed to the top of the threaded post 8, and a groove is provided on the knob 12. An insert block 14 is fixed on the inner wall of the outer shell 13, and the bottom end of the insert block 14 can be inserted into the groove.

[0029] In this embodiment, the knob 12 facilitates the operator to rotate the threaded post 8, and the groove provides an insertion space for the insert 14. The insert 14 is fixed to the inner wall of the outer shell 13 and can lock the knob 12 when the outer shell 13 is closed. This structure, by inserting the insert 14 into the groove, can prevent the threaded post 8 from loosening.

[0030] In a further preferred embodiment of this utility model, the limiting plate 9 has an opening, and the inner diameter of the opening is larger than that of the threaded post 8.

[0031] In this embodiment, the threaded column 8 passes through the opening on the limiting plate 9. When the threaded column 8 is rotated, the limiting plate 9 will not rotate with the threaded column 8, but will only move along the axial direction of the threaded column 8 until the tooth block 11 and the rack 6 are limited.

[0032] In a further preferred embodiment of the present invention, the connecting plate 15 is provided with a mounting hole, the mounting hole is adapted to the bolt 16, and a nut is provided on the bolt 16.

[0033] In this embodiment, the bolt 16 is passed through the mounting hole on the connecting plate 15, and then the nut is screwed onto the bolt 16 and tightened to make the connecting plate 15 firmly connected, thereby fixing the outer shell 13.

[0034] In a further preferred embodiment of this utility model, the inner diameter of the guide sleeve 5 is larger than that of the rack 6, allowing it to pass through.

[0035] In this embodiment, the rack 6 is passed through the guide sleeve 5. Since the inner diameter of the guide sleeve 5 is larger than that of the rack 6, the rack 6 can move smoothly within the guide sleeve 5. After being adjusted to a suitable position, it is fixed by the limiting mechanism. The guide sleeve 5 provides a path for the rack 6 to pass through. Its inner diameter is larger than that of the rack 6 to avoid jamming between the two and ensure that the rack 6 can move flexibly, which is convenient for subsequent limiting operations.

[0036] In summary, compared with related technologies, by reinforcing the cable connection with the reinforced shell 1, strengthening the insulation with the insulating sleeve 2, improving the sealing with the sealing sleeve 3 and the pressure sleeve 4, securing the connection with the rack 6, guide sleeve 5 and limiting mechanism, and strengthening the protection with the outer shell 13, connecting plate 15, bolts 16, etc., the overall strength, rigidity and shock resistance of the cable joint are improved, the risk of damage caused by external impact is reduced, and the occurrence of safety accidents is reduced.
