Description

[0002] A cable is a wire made of one or more mutually insulated conductors and an outer insulating protective layer, laid underground, in the air, etc. There are usually two types: power cables and control cables. Power cables are mainly used for the transmission and distribution of electric energy; control cables are mainly used for lines such as measurement, protection, and control. Cables have the characteristics of being energized inside and insulated outside.
[0003] Cables are generally used for overhead power transmission. When installed, multiple cables are usually arranged side by side to transmit power. To improve the safety of the cables when exposed to wind, the side-by-side cable lines will maintain a certain degree of slack. However, when the cables are exposed to wind, they will swing, and in this way, the side-by-side cables are likely to be twisted together, causing a cable short circuit. The swing amplitude can be reduced by increasing the cable tension, but at the same time, the buffering ability of the cable when exposed to wind will be reduced, and the cable is likely to break. Therefore, an anti-twisting cable protection device is proposed to be installed on the surface of the cable to prevent the side-by-side cables from being twisted together when exposed to wind.

[0027] It should be noted that all the directional indications in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.
[0028] In the present application, unless otherwise clearly defined and limited, the terms "connection", "fixation", etc. shall be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.
[0029] In addition, in the present application, descriptions such as "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present application.
[0030] During installation, generally multiple cables are used to transmit electricity side by side. To improve the safety of the cables when exposed to wind, the side-by-side cables will maintain a certain degree of slack. When the cables are affected by wind, they will swing, and in this way, the side-by-side cables are likely to become entangled with each other, resulting in a short circuit of the cables.
[0031] In the related art, the swing amplitude is reduced by increasing the cable tension, but at the same time, the buffering ability of the cable when affected by wind is reduced, which is likely to cause the cable to break.
[0032] To solve the problems in the related art to a certain extent, the embodiments of the present application provide an anti-winding cable protection device. When the cable sways under the action of wind, the gravity ball 12 pulls the semi-push ring 5 to move leftward through the pull rope 13 under inertia, pushes the movable tube 6 out of the through hole 8, drives the push rod 16 to move leftward, and the disk rod 15 connected elastically blocks the left end of the air outlet pipe 14 under the action of elastic connection. When the right end head 1 sways up and down, air flow enters the right end head 1, and the elastic skin 17 gradually expands as the air flow fills in. The two expanded elastic skins 17 increase the minimum distance that the two cables can approach, effectively preventing adjacent cables from winding together. When the wind force decreases or stops, the tension telescopic rod 4 pulls the semi-push ring 5 to reset. The movable tube 6 retracts into the through hole 8 under the action of the connecting spring 7. The semi-push ring 5 pushes the push rod 16 to apply a thrust to the disk rod 15, so that the disk rod 15 disengages from blocking the air outlet pipe 14, and the air flow in the elastic skin 17 can leak out from the air outlet pipe 14.
[0033] The present application will be described below with reference to the accompanying drawings and specific embodiments:
[0034] Combined with Figures 1 - 5 the embodiments of the present application provide an anti-winding cable protection device, including a right end head 1. The number of the right end heads 1 is two. The left side surfaces of the two right end heads 1 are fixedly connected with inner cavity half cylinders 2. The left ends of the two inner cavity half cylinders 2 are fixedly connected with left end heads 3. Both between the two right end heads 1 and between the two left end heads 3 are connected by bolt rods. The left side surface of the right end head 1 is slidably inserted with a semi-push ring 5. The right side surface of the semi-push ring 5 is fixedly installed with a tension telescopic rod 4. The right end of the tension telescopic rod 4 is fixedly connected with the right inner wall of the right end head 1. A through hole 8 is formed in the outer ring surface of the right end head 1. The inside of the through hole 8 is slidably inserted with a movable tube 6. The outer ring surface of the movable tube 6 and the inner wall of the through hole 8 are elastically connected by a connecting spring 7. One end of the movable tube 6 close to the inside of the right end head 1 is elastically connected with an elastic sealing plate 9. A stress rod 10 is arranged on the side of the elastic sealing plate 9 away from the movable tube 6. The stress rod 10 is fixedly connected with the corresponding movable tube 6. The other end of the stress rod 10 is in sliding contact with the outer ring surface of the adjacent semi-push ring 5. An inner fixing plate 11 is fixedly connected inside the inner cavity half cylinder 2. A pull rope 13 is slidably inserted inside the inner fixing plate 11. The left end of the pull rope 13 is fixedly connected with a gravity ball 12. The right end of the pull rope 13 is fixedly connected with the left side surface of the semi-push ring 5. The right end surface of the right end head 1 is fixedly inserted with an air outlet pipe 14. A disk rod 15 is arranged at the left end of the air outlet pipe 14. The middle position of the disk rod 15 is elastically rotatably connected with the right inner wall of the right end head 1. A push rod 16 is arranged on the left side of the end of the disk rod 15 away from the air outlet pipe 14. The left end of the push rod 16 is fixedly connected with the semi-push ring 5. Elastic skins 17 are arranged on the sides of the two inner cavity half cylinders 2 away from each other. The four sides of the elastic skins 17 are fixedly connected with the inner cavity half cylinders 2.
[0035] The connecting spring 7 has a tendency to pull the movable tube 6 into the through hole 8. The tension telescopic rod 4 has a tendency to pull the semi-pushing ring 5 to move to the right, and then pulls the gravity ball 12 through the pull rope 13. When the right side surface of the semi-pushing ring 5 contacts the inner wall of the right end head 1, the push rod 16 is pushed to separate the disc rod 15 from the air outlet pipe 14. When the semi-pushing ring 5 moves to the left, it drives the push rod 16 to move to the left, so that the disc rod 15 plugs the left end of the air outlet pipe 14 under elastic connection. At the same time, when the semi-pushing ring 5 moves to the left, it can push the movable tube 6 out of the through hole 8.
[0036] In some embodiments, the mutually approaching surfaces of the two inner cavity half cylinders 2 are both semi-circular structures, and the mutually remote surfaces of the two inner cavity half cylinders 2 are both through groove structures.
[0037] Specifically, the air flow entering the inner cavity half cylinder 2 causes the elastic skin 17 to expand through the through groove structure.
[0038] In some embodiments, the outer end of the through hole 8 is a tapered enlarged hole structure. One end of the movable tube 6 far from the axis of the right end head 1 is fixedly connected with an elastic cylinder 18. A plurality of elastic struts 19 are arranged inside the elastic cylinder 18, and the elastic struts 19 are elastically connected with the end surface of the movable tube 6.
[0039] Specifically, when the movable tube 6 moves out of the through hole 8, the elastically connected elastic struts 19 can push the outer end of the elastic cylinder 18 to open, increasing the area of the elastic cylinder 18 entering the air flow and accelerating the expansion speed of the elastic skin 17.
[0040] In some embodiments, the axis of the movable tube 6 is perpendicular to and intersects with the axis of the right end head 1. The number of through holes 8 opened in each right end head 1 is multiple, and the multiple through holes 8 are equidistantly distributed inside the right end head 1.
[0041] In some embodiments, the shapes of the right end head 1 and the left end head 3 are both semi-circular rings. Soft semi-rings 20 are rotatably inserted into the inner ring surfaces of the two left end heads 3 and the inner ring surfaces of the two right end heads 1.
[0042] Specifically, the soft semi-ring 20 reduces the abrasion of the right end head 1 and the left end head 3 on the cable.
[0043] In some embodiments, the semi-pushing ring 5 is coaxially arranged with the right end head 1, and the diameter of the outer ring surface at the left end of the two semi-pushing rings 5 is smaller than the diameter of the outer ring surface at the right end.
[0044] Specifically, when the semi-pushing ring 5 moves to the left, it can push the movable tube 6 out of the through hole 8.
[0045] In some embodiments, the outer ring surface of the semi-pushing ring 5 is an uneven surface. A friction plate 21 is arranged on the outer ring side of the semi-pushing ring 5, and the right end of the friction plate 21 is fixedly connected with the left side surface of the corresponding right end head 1.
[0046] Specifically, the frictional force between the friction plate 21 and the semi-push ring 5 reduces the reset speed of the semi-push ring 5, extends the blockage of the air outlet pipe by the disc rod, and prevents the elastic skin 17 from expanding and contracting alternately when the wind force is unstable, thus effectively preventing adjacent cables from being wound together.

Moreover, the specific features, structures, materials, or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.
