[0002] When installing high-voltage cable accessories, the insulation shielding layer of the cable needs to be stripped off. At present, the method of scraping off the insulation shielding with glass pieces is usually used for non-strippable insulation shielding materials. This method requires a lot of time to repair the cable insulation shielding, and if used improperly, the glass pieces will cut the hands and cause harm to the operator; in addition, in winter, the insulation shielding of the cable will harden, which will increase the difficulty of operation to a greater extent and make it difficult to ensure the timeliness of installation. In the process of repairing submarine cables, the impact of complex environmental factors at sea needs to be taken into account, and the repair projects of submarine cables pay special attention to timeliness. Adding one more day to the construction period is a very large loss. Summary of the invention

These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Figure 1 , Figure 2 and Figure 3 A heating type fast cable stripping and cutting knife is shown, comprising a main operating cylinder 1, on which a plurality of first electric rollers 3 are movably mounted through a first internal support rod 2, an internal assembly ring 5 is fixedly mounted on the inner side of the main operating cylinder 1 through a second internal support rod, a plurality of second electric-controlled rollers 7 are movably mounted on the inner side of the main operating cylinder 1 through a third internal support rod 6, an electric heating ring 9 controlled by a thermocouple module 8 is fixedly mounted on the inner side of the internal assembly ring 5, an internal annular guide rail 10 is fixedly mounted on the inner side of the main operating cylinder 1, and a retractable circular cutting blade 11 is movably mounted inside the internal annular guide rail 10.

[0022] The electric heating ring 9 is composed of a resistance heating layer and an electromagnetic induction heating layer, which heat the cable insulation shield and the conductor respectively, and the non-peelable insulation shield is changed into a peelable insulation shield by the heating device.

[0023] Working principle: People insert the cable into the inside from the opening on one side of the main operating cylinder 1, use the first electric roller 3 to control the cable to be transported inside the main operating cylinder 1, and then the internal annular guide rail 10 drives the retractable circular cutting blade 11 inside it to cut the insulation shield from the insulation, and then tear it off through the second electric control roller 7 to achieve the stripping of the insulation shield.

[0024] In order to cooperate with the internal movable assembly, the main operating cylinder 1 is welded and fixed with an internal assembly bracket at the connecting end of the first internal support rod 2 and the third internal support rod 6.

[0025] In order to facilitate the adjustment of the installation angles of the first internal support rod 2 and the third internal support rod 6, the first internal support rod 2 and the third internal support rod 6 are both composed of a flip adjustment frame 12 movably mounted on the internal assembly bracket and a lateral adjustment support rod 13 for controlling the flip adjustment frame 12.

[0026] The lateral adjustment support rod 13 controls the flip adjustment of the flip adjustment frame 12 by telescoping, so as to change the distance between the first electric roller 3 and the second electric control roller 7 and the cable.

[0027] The first electric roller 3 is in contact with the surface of the cable to control the translational transportation of the cable inside the main operating cylinder 1, while the second electric roller 7 is used to reel off the stripped insulating shielding layer.

[0028] In order to cooperate with the electric control adjustment, the retractable circular cutting blade 11 includes an inner adjustment ring 111 slidably assembled in the inner annular guide rail 10, an external adjustment motor 112 fixed on the outer surface of the main operating cylinder 1, an adjustment gear 113 installed on the output shaft of the external adjustment motor 112, an arc-shaped assembly groove opened on the inner surface of the inner adjustment ring 111, an arc-shaped adjustment arm 114 movably installed in the arc-shaped assembly groove, an inner adjustment support rod 115 for controlling the arc-shaped adjustment arm 114 and a first cutting blade 116 movably installed at the end of the arc-shaped adjustment arm 114.

[0029] The external adjustment motor 112 drives the adjustment gear 113 to rotate, and then uses the connecting gear 113 to control the rotation of the inner adjustment ring 111, thereby changing the angle of the arc adjustment arm 114 and the inner adjustment strut 115, and uses the arc adjustment arm 114 to drive the first cutting blade 116 at the end to extrude and peel off the insulation shielding on the cable surface, and the inner adjustment strut 115 controls the flipping angle of the arc adjustment arm 114 by telescoping.

[0030] In order to facilitate monitoring and controlling the cutting depth, a pressure control module 117 is provided at the end of the arc-shaped adjustment arm 114 and the connection end of the first cutting blade 116 .

[0031] When the arc-shaped adjustment arm 114 controls the first cutting blade 116 to contact and cut the insulation shield on the outer surface of the cable by flipping, the pressure control module 117 will sense the downward pressure and judge the cutting depth according to the size of the downward pressure, thereby avoiding excessive cutting.

[0032] In order to improve the separation efficiency of the insulation shield, a plurality of elastic stripping claws 14 are fixedly mounted on the outer arc surface of the first electric roller 3 .

[0033] In order to facilitate lateral installation, an arc-shaped opening is provided inside the arc-shaped adjustment arm 114 .

[0034] In order to facilitate storage and expansion, an auxiliary adjustment arm 15 and an auxiliary support rod 16 for controlling the auxiliary adjustment arm 15 are movably installed inside the arc-shaped opening.

[0035] The auxiliary support rod 16 controls the turning of the auxiliary adjustment arm 15 by extending and retracting, so as to facilitate contact between the auxiliary adjustment arm 15 and the insulation shielding of the cable surface layer as required.

[0036] In order to cut the insulating shield in another way, a second cutting blade 17 is mounted on the end of the arc-shaped adjustment arm 15 .

[0037] In order to prevent the internal heat from overflowing, the openings on both sides of the main operating cylinder 1 are provided with lateral heat insulation covers 18 .

[0038] By arranging heat insulation covers at the openings on both sides of the main operating cylinder 1 according to the outer diameter of the cable, heat spillover can be effectively reduced, thereby reducing energy consumption.

[0039] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
