[0002] Cable is one of the important components for the operation of the power system. The cable contains metallic copper, insulation, anti-interference layer and protective layer. The cable plays the role of a power road in power transmission. At this stage, cables are often laid underground. When laying cables underground, it is generally necessary to avoid joints. Since the joints may be easily damaged, the cable joints may be damaged when buried underground, and the copper metal inside the cable may be affected by oxidation and leakage. Therefore, longer cables are used for laying cables, and they are cut off for laying. At the same time, in some line renovation projects, waste cables will be recycled. The copper material inside the recycled cables is a relatively scarce resource, and the protective layer of the cables will be damaged to a certain extent due to oxidation. The cables can no longer be used, and the copper material inside the cables needs to be peeled before they can be removed.

[0003] When the existing cable recycling device recycles the cable, the protective layer of the cable is cut in half to make the metal copper in the cable leak out and be wound for recycling; the protective layer separated in half on the cable has a high hardness, and the cut protective layer is too long, which may hinder the normal work of the personnel and affect the convenience of recycling the cut protective layer. Summary of the invention

[0025] Example

[0026] Please refer to Figures 1 to 3The present invention proposes a cable sheath recovery device, comprising a workbench 1 and a roller cutter 2. Two roller cutters 2 are arranged longitudinally and rotatably mounted on a bracket 11 of the workbench 1 to clamp the cable and cut it in half. A turntable 3 is rotatably mounted on the workbench 1 and located beside the roller cutter 2. A plurality of groups of mutually meshing knife bodies 4 are rotatably mounted on the turntable 3. Two guide plates 5 are mounted on the workbench 1. The two guide plates 5 can squeeze a group of knife bodies 4 on the turntable 3 to mesh and cut the cable into interval segments. In this solution, the turntable 3 needs to be connected and driven by a motor, and the rotation speed of the turntable 3 does not need to be too fast. During operation, the motor drives the turntable 3 to rotate, and a group of blades 4 on the turntable 3 will clamp the cable, and the blade 4 will engage the wire sheath embedded in the cable. At this time, the blade 4 will be embedded in the wire sheath to process the wire sheath in sections. The blade 4 will continue to be embedded in the wire sheath and will contact the copper body inside the cable. At the same time, the two blades 4 will not completely cut the wire sheath. After cutting, the knife marks left are two semicircular, and the two ends of the two knife marks are not connected; after the blade 4 is embedded in the wire sheath, the rotation of the disk body can drive the cable to move horizontally through the conductor; further, the segmented cable will enter between the two rollers 2, and the roller 2 will cut the wire sheath of the cable in half. When the two rollers 2 are embedded in the wire sheath, a cutting seal will be generated, which will connect the ends of the two semicircular knife marks to form a circle. At this time, the segmented wire sheath will be completely cut off and fall off, forming a segmented wire sheath for easy storage. Furthermore, in the present solution, two guide plates 5 are installed on the workbench 1, and the guide plates 5 are used to guide the two blade bodies 4 to engage and cut the cable.

[0027] In a specific embodiment, refer to Figure 1 or Figure 3 A slot 31 parallel to the rotation axis of the turntable 3 is provided on the turntable 3, and the direction of the slot 31 is parallel to the rotation axis of the turntable 3. There are two cutter bodies 4 on a set of cutter bodies 4, and the two cutter bodies 4 are rotatably installed with connecting strips 41, and the connecting strips 41 are located in the slot 31. A slide bar 42 is slidably installed between the two connecting strips 41, so that the two connecting strips 41 can slide closer to or farther away from each other through the slide bar 42. An elastic member 43 is sleeved on the slide bar 42, and the elastic member 43 is a spring. The two ends of the spring respectively resist the two connecting strips 41 in the same slot 31. When the two cutter bodies 4 are close to each other to cut and segment the cable, the two connecting strips 41 at this time will squeeze the spring, and the spring will be in a compressed state. When the two cutter bodies 4 are not squeezed by the guide plate 5, the spring will release the elastic force, so that the two cutter bodies 4 are separated from the cable to avoid hindering the movement of the cable.

[0028] In a specific embodiment, refer to Figure 1 or Figure 3 The width of the slot 31 is greater than the range of movement of the connecting strip 41. The connecting strip 41 in the present application will have a rotation range. The range width of the slot 31 needs to avoid hindering the range of movement of the connecting strip 41, so it is achieved by increasing the width of the slot 31.

[0029] In a further embodiment, in the present application, the spring needs to be located in the slot 31 and cannot protrude from the slot 31. If the spring protrudes from the slot 31, it may be squeezed by the cable and damaged, or the spring cannot be deformed.

[0030] In a specific embodiment, refer to Figure 3 The cutter body 4 includes a rotating body 44 and a blade 45. In this embodiment, the cutter body 4 is composed of the rotating body 44 and the blade 45. A plurality of flat steps 32 are circumferentially arranged on the turntable 3, wherein one end of the rotating body 44 is rotatably mounted on the step 32 via a rotating shaft, and the other end of the rotating body 44 is used to mount the cutter body 4. The rotation of the turntable 3 will preferentially allow the end of the rotating body 44 close to the rotating shaft to enter between the two guide plates 5. The connecting strip 41 is rotatably mounted on the rotating body 44 and is located in the slot 31. The cutter body 4 and the rotating body 44 are fixed by screws.

[0031] In a specific embodiment, refer to Figure 3 The blade 45 has a concave arc shape. When the two blades 45 cut against each other, a ring can be formed. Since there is metallic copper in the cable, the blade body 4 is set to an inwardly concave arc shape to protect the blade 45 from cutting the metal. At the same time, it can protect the metallic copper in the cable from being cut off, so that the complete copper body can be wound and stored.

[0032] In a specific embodiment, refer to Figure 2 or Figure 3 The interval between the rotating axes of two blade bodies 4 in the same group is smaller than the thickness of the turntable 3.

[0033] In a specific embodiment, refer to Figure 3 The axis of rotation of the turntable 3 is parallel to the axis of rotation of the hob 2; when the turntable 3 is moved to the cable between the hobs 2 for cutting, the two semicircular cuts form a circle.

[0034] A cable sheath recovery method, using the cable sheath recovery device of the above scheme, comprises the following steps:

[0035] S1: firstly place the cable between a set of blade bodies 4, and rotate the turntable 3 so that a set of blade bodies 4 are squeezed by the guide plate 5 to pre-clamp the cable;

[0036] S2: Rotate the turntable 3 so that a set of cutters 4 can cut the cable sheath into sections, while driving the cable to move toward the hob 2;

[0037] S3: Introduce the end of the cable leaking from the turntable 3 into between the two rollers 2, and let the rollers 2 cut and clamp the cable;

[0038] S4: The cable sheath moved out from the roller cutter 2 is stripped and segmented.
