Description

Technical Field

[0001] This utility model belongs to the technical field of cable auxiliary accessories, and specifically relates to a cable sheath. Background Technology

[0002] Wind turbine generators primarily transmit electricity via cables. During installation, the cables typically enter the tower from the nacelle and hang at the bottom of the nacelle. As the wind turbine operates, the cables swing with it, causing them to twist. Over time, this friction between the cables can lead to wear. To prevent wear and tear, cable sheaths are usually placed over the cables.

[0003] CN219329582U discloses a clamp-type combined sheath, including an outer sheath ring and an inner sheath ring. The outer sheath ring includes a first outer ring and a second outer ring, both of which are metal sheets with a semi-circular radial cross-section. The outer sheath ring is a cylindrical structure formed by joining the first and second outer rings. The inner sheath ring is fixed to the inner side of the arc of the outer sheath ring. There are multiple inner sheath rings, each individually fixed to the inner side of either the first or second outer ring. Although this cable sheath can separate cables, it can only separate cables close to the inner wall of the outer sheath ring. It cannot separate cables in the middle. Furthermore, the outer sheath ring has multiple outward-protruding bolts. During cable installation, a central ring is set on the outer side. When the bolts protruding from the sheath collide with the central ring on the outer side, the rubber pad of the central ring is easily damaged. Utility Model Content

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a cable sheath includes an outer shell and a fixing component. The outer shell has an arc-shaped outer perimeter, and the two outer shells are connected to form a hollow cylindrical structure. The fixing component is fixed inside the outer shell and includes an outer fixing component and a central fixing component. The outer fixing component is fixed to the inner wall of the outer shell, and the cable on the outer perimeter is fixed inside the outer shell through the outer fixing component. The two ends of the central fixing component are fixed between the two outer shells, and the middle part of the central fixing component passes through the axis of the cylinder formed by the two outer shells. The cable in the center is fixed inside the outer shell through the central fixing component.

[0005] The outer casing is provided with a plurality of first grooves that are recessed into the outer casing, and the first grooves are provided with first through holes. Bolts pass through the first through holes to fix the external fixing assembly to the outer casing.

[0006] The lower end of the outer shell is provided with a second recessed groove, and there are two second grooves. The two second grooves are respectively provided at the two ends of the lower end of the outer shell. The second groove is provided with a second through hole. The axis of the second through hole is perpendicular to the length direction of the central fixing component. The bolt passes through the second through hole to connect the lower parts of the two outer shells 1.

[0007] The upper end of the outer shell is provided with two connecting ears, which are respectively located at the ends of the upper end of the outer shell. Each connecting ear is provided with a third through hole, the axis of which is perpendicular to the length direction of the central fixing component. Bolts pass through the third through holes to connect the upper parts of the two outer shells.

[0008] The number of external fixation components is multiple, and each external fixation component includes a first external fixation clip and a second external fixation clip. Both ends of the first external fixation clip and the second external fixation clip are provided with a fourth through hole. The bolt passes through the first through hole, the fourth through hole of the first external fixation clip, and the fourth through hole of the second external fixation clip in sequence to fix the external fixation component to the outer shell. The middle part of the opposite side of the first external fixation clip and the second external fixation clip are provided with an arc-shaped groove. The arc-shaped groove is provided with anti-slip texture, which is a plurality of protrusions extending horizontally along the arc-shaped groove.

[0009] The number of arc-shaped grooves is one or more, and the multiple arc-shaped grooves are arranged in an array along the horizontal direction of the external fixing component.

[0010] The outer periphery of the end of the first external fixing clip away from the second external fixing clip is arc-shaped, and the two ends of the arc shape are provided with a third groove that matches the first groove. The fourth through hole on the first external fixing clip is provided in the third groove.

[0011] The central fixing assembly includes a fixing plate and a central fixing clip. The two ends of the central fixing clip are fixed to the middle of the fixing plate by bolts. The middle of the central fixing clip is arc-shaped. The central fixing clip and the fixing plate form a semi-circular gap. The two ends of the fixing plate are provided with a fifth through hole. The bolt passes through the second through hole and the fifth through hole to fix the central fixing assembly to the lower part of the outer shell. The bolt passes through the third through hole and the fifth through hole to fix the central fixing assembly to the upper part of the outer shell.

[0012] The outer shell is provided with a plurality of circular through holes and oblong through holes. The circular through holes are arranged in an array along the circumference and vertical direction of the outer shell, and the oblong through holes are located at the upper and lower ends of the circular through holes. The oblong through holes are arranged in an array along the circumference of the outer shell.

[0013] The cable sheath obtained through the above technical solution has the following beneficial effects:

[0014] A central fixing component was added inside the sheath, which can separate the middle section of the cable and reduce friction in the middle section of the cable when twisting.

[0015] Grooves have been added to the sheath to prevent bolts from being exposed when they are fixed with bolts, thus preventing the bolts from colliding with the central ring on the outside of the sheath and extending the service life of the central ring gasket.

[0016] There are no exposed connecting ears at the bottom of the sheath, so there is no restriction when lifting it when it is installed in the center ring position. It can be directly installed and slid into the center ring from the top without the need for installation inside the center ring, making the operation more convenient and quick.

Detailed Implementation

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Unless otherwise defined, the technical terms used in the following embodiments have the same meaning as commonly understood by those skilled in the art to which this utility model pertains.

[0027] The present invention will be further explained below with reference to the embodiments and accompanying drawings. It should be understood that the present invention is not limited to the specific embodiments described.

[0028] like Figure 1 , Figure 2 , Figure 7 As shown, this utility model proposes a cable sheath, including an outer shell 1 and a fixing component 2. There are two outer shells 1, each with an arc-shaped outer perimeter. The two outer shells 1 are connected to form a hollow cylindrical structure. The fixing component 2 is fixed inside the outer shell 1. The fixing component 2 includes an outer fixing component 21 and a central fixing component 22. The outer fixing component 21 is fixed to the inner wall of the outer shell, and the outer cable is fixed inside the outer shell 1 via the outer fixing component 21. The two ends of the central fixing component 22 are fixed between the two outer shells 1, and the middle of the central fixing component 22 passes through the axis of the cylinder formed by the two outer shells 1. The central cable is fixed inside the outer shell 1 via the central fixing component 22, which can effectively separate the cables and reduce mutual friction between the cables when twisting occurs.

[0029] like Figure 3 As shown, the outer shell 1 is provided with a plurality of first grooves 11 that are recessed into the outer shell 1. The first grooves 11 are provided with first through holes 11a. The bolts pass through the first through holes 11a to fix the external fixing component 21 to the outer shell 1, which can effectively prevent the bolts from being exposed and keep the outer surface of the outer shell 1 smooth.

[0030] The lower end of the outer shell 1 is provided with a second recess 12 that is recessed into the outer shell. There are two second recesses 12, which are respectively provided at the two ends of the lower end of the outer shell 1. A second through hole 12a is provided on the second recess 12. The axis of the second through hole 12a is perpendicular to the length direction of the central fixing component 22. The bolt passes through the second through hole 12a to connect the lower parts of the two outer shells 1, so that the lower part of the outer shell 1 remains smooth and is not restricted when it is installed in the position of the central ring.

[0031] The upper end of the outer shell 1 is provided with a connecting ear 13. There are two connecting ears 13, which are respectively located at the upper end of the outer shell 1. The connecting ear 13 is provided with a third through hole 13a. The axis of the third through hole 13a is perpendicular to the length direction of the central fixing component 22. The bolt passes through the third through hole 13a to connect the upper parts of the two outer shells 1.

[0032] like Figure 4As shown, there are multiple external fixing components 21. Each external fixing component 21 includes a first external fixing clip 211 and a second external fixing clip 212. Both ends of the first external fixing clip 211 and the second external fixing clip 212 are provided with a fourth through hole 21a. The bolt passes through the first through hole 21a, the fourth through hole 21a of the first external fixing clip 211, and the fourth through hole 21a of the second external fixing clip 212 in sequence to fix the external fixing component 21 to the outer shell 1. An arc-shaped groove 21b is provided in the middle of the opposite side of the external fixing clip 212. The outer cable is fixed in the arc-shaped groove 21b of the external fixing assembly 21 by the first external fixing clip 211 and the second external fixing clip 212. The arc-shaped groove 21b is provided with anti-slip texture, which is a plurality of protrusions extending horizontally along the arc-shaped groove 21b. It can effectively increase the friction between the cable and the first external fixing clip 211 and the second external fixing clip 212, and prevent relative sliding between the cable and the external fixing assembly 21.

[0033] like Figure 5 As shown, the number of arc-shaped grooves 21b is one or more, and the multiple arc-shaped grooves 21b are arranged in an array along the horizontal direction of the external fixing component 21. Multiple arc-shaped grooves 21b can be set as needed to increase the number of cable strands within an external fixing component 21.

[0034] The outer periphery of the end of the first external fixing clip 211 away from the second external fixing clip 212 is arc-shaped, and the two ends of the arc shape are provided with a third groove 211a that fits into the first groove 11. The fourth through hole 21a on the first external fixing clip 211 is located in the third groove 211a, so that the first external fixing clip 211 fits against the inner wall of the outer shell 1, making it easier to fix it on the inner wall of the outer shell 1. Since the second external fixing clip 212 does not fit against the inner wall of the outer shell 1, the shape of its outer side is not restricted, as long as it does not collide with other fixing components 2.

[0035] like Figure 6 As shown, the central fixing component 22 includes a fixing plate 221 and a central fixing clamp 222. The two ends of the central fixing clamp 222 are fixed to the middle of the fixing plate 221 by bolts. The middle of the central fixing clamp 222 is arc-shaped. The central fixing clamp 222 and the fixing plate 221 form a semi-circular gap. The two ends of the fixing plate 221 are provided with a fifth through hole 221a. The bolt passes through the second through hole 12a. The fifth through hole 221a fixes the central fixing component 22 to the lower part of the outer shell 1. The bolt passes through the third through hole 13a and the fifth through hole 221a to fix the central fixing component 22 to the upper part of the outer shell 1. The central cable is fixed in the semi-circular gap formed between the central fixing clamp 222 and the fixing plate 221.

[0036] The outer casing 1 is provided with multiple circular through holes 14 and oblong through holes 15. The circular through holes 14 are arranged in an array along the circumference and vertical direction of the outer casing. The oblong through holes 15 are located at the upper and lower ends of the circular through holes 14 and are arranged in an array along the circumference of the outer casing 1. Cable ties are passed through two adjacent circular through holes 14 or oblong through holes 15 respectively to individually tie the small cable to the outer casing 1, making it more flexible to use. At the same time, providing multiple circular through holes 14 and oblong through holes 15 on the cylinder can reduce the weight of the outer casing 1 and also ensure heat dissipation of the cable.

[0037] In use, first take out the outer shell 1, place the cable that needs to be separated on the outer periphery into the arc groove 21 between the first outer fixing clip 211 and the second outer fixing clip 212, fit the first outer fixing clip 211 against the inner wall of the outer shell 1, and insert the bolt through the first through hole 11a in the first groove 11 to fix the outer fixing component 2 to the inner wall of the cable. Then, place the cable that needs to be separated in the middle into the semi-circular gap between the central fixing clip 222 and the fixing plate 221, and fix the central fixing clip 222 to the fixing plate 221 with bolts. Then, pass the bolts through the second through hole 12a (or the third through hole 13a) of one of the outer shells 1, one of the fifth through holes 221a of the central fixing clip 222, and the second through hole 12a (or the third through hole 13a) of the other outer shell 1 in sequence to fix the two ends of the central fixing clip 222 between the two outer shells 1, thus completing the separation of the outer periphery and center of the cable.
