Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a cable with a protection structure. Background Art

[0002] A cable is usually composed of several or several groups of wires. A cable is usually a rope-like cable formed by stranding several or several groups of wires (at least two wires in each group). The wires in each group are insulated from each other and are often twisted around a central wire, and the whole is covered with a highly insulating covering layer. It is mostly erected in the air or installed underground or underwater for telecommunications or power transmission. Usually, cables are used for long-distance telecommunications or power transmission. After a section of cable is used up, it needs to be connected to the next section. No matter which connection method is used during the connection, the connection will emit more heat than other positions during use. This leads to that when normal heat dissipation is carried out, when the heat of other positions is completely dissipated, only a part of the heat at the connection is taken away, resulting in continuous heat accumulation, which will not only affect the service life of the connection, but even cause the connection to burn when the temperature is too high, posing a safety hazard.

[0003] The publication number is: CN219717746U, which discloses a cable protection pipe with a heat dissipation structure. This cable protection pipe with a heat dissipation structure, through the cooperation of the air inlet hopper, the spiral heat dissipation pipe and the air outlet hopper, enables cold air to enter the inside of the spiral heat dissipation pipe and flow for a longer distance outside the cable connection, and at the same time speeds up the flow rate of the cold air, so as to take away more heat. The arranged flow disturbing bumps and external threads increase the contact area between the cold air and the inner wall of the side of the spiral heat dissipation pipe close to the inner pipe while disturbing the cold air, so that the cold air conducts more comprehensive heat exchange inside the spiral heat dissipation pipe. However, in actual use, the external weather is changeable. The above cable protection pipe dissipates heat from the cable connection by allowing cold air to enter the spiral pipe. However, since the inside of the spiral pipe is closed and the spiral pipe is wound around the inner pipe for multiple turns, when it rains and blows outside, the cold air will blow raindrops into the spiral pipe. After the rainwater enters the spiral pipe, under the action of gravity, the rainwater will accumulate at the bottom of the spiral pipe. If it accumulates for a long time, one end of the spiral pipe will be blocked, thus affecting the protection effect on the cable.

[0004] Based on this, a cable with a protection structure is now provided, which can eliminate the drawbacks of the existing device. Content of the Utility Model

Detailed implementation mode

[0025] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Embodiment 1

[0027] In one embodiment, as Figures 1-6 shown, a cable with a protection structure includes a first cable body 11 and a second cable body 12. The first cable body 11 and the second cable body 12 are respectively sleeved with a first protective tube 13 and a second protective tube 14. A plurality of mounting grooves are provided on both the first protective tube 13 and the second protective tube 14. Clamping blocks 15 are slidably arranged in the mounting grooves. A plurality of stopping blocks 16 are fixedly arranged at the bottom ends of the clamping blocks 15. Sliding plates are fixedly arranged at both ends of the clamping blocks 15. Sliding grooves are provided at positions corresponding to the sliding plates on the inner sides of the mounting grooves. Return springs 17 are provided between the bottom ends of the sliding plates and one sides of the sliding grooves. Limiting components for simultaneously limiting and fixing a plurality of clamping blocks 15 are provided on both the first protective tube 13 and the second protective tube 14. First fixing plates are fixedly arranged inside one ends of the first protective tube 13 and the second protective tube 14. Sealing rings 20 are closely attached to one sides of the first fixing plates. Fixing mechanisms for fixing the sealing rings 20 are provided on both the first protective tube 13 and the second protective tube 14. Heat dissipation mechanisms for facilitating heat dissipation at the connection of the first cable body 11 and the second cable body 12 are provided on both the first protective tube 13 and the second protective tube 14. The fixing mechanism facilitates the limiting and fixing of the sealing ring 20, and the heat dissipation mechanism facilitates accelerating the air flow speed at the connection of the first cable body 11 and the second cable body 12, so as to facilitate heat dissipation at the connection of the first cable body 11 and the second cable body 12;

[0028] The limiting component includes a threaded sleeve 18. Threaded sleeves 18 are sleeved on both the first protection tube 13 and the second protection tube 14. Inner threads are provided on the inner sides of the threaded sleeves 18, and external threads are provided on the outer sides of the clamping blocks 15. The edges on one side of the clamping blocks 15 are chamfered, and the edges at one end of the threaded sleeves 18 are chamfered. A limiting ring 19 is closely arranged at one end of the threaded sleeve 18, and the limiting ring 19 is arranged on the first protection tube 13 and the second protection tube 14. During use, when the first protection tube 13 and the second protection tube 14 need to be installed, the first protection tube 13 and the second protection tube 14 are respectively sleeved on one ends of the first cable main body 11 and the second cable main body 12. Subsequently, the first cable main body 11 and the second cable main body 12 are connected. After the connection is completed, one ends of the first protection tube 13 and the second protection tube 14 are made to be closely adjacent. Then, the threaded sleeves 18 are respectively slid on the first protection tube 13 and the second protection tube 14. When one end of the threaded sleeve 18 is closely adjacent to the chamfered portion of the clamping block 15, the clamping block 15 slides in the installation groove. When the internal thread inside the threaded sleeve 18 is engaged with the external thread on the clamping block 15, the stop blocks 16 on one side of the clamping block 15 are closely adjacent to the first cable main body 11 and the second cable main body 12, so that the first protection tube 13 and the second protection tube 14 are respectively fixed on the first cable main body 11 and the second cable main body 12. Subsequently, the threaded sleeve 18 is rotated. Under the action of the thread, the threaded sleeve 18 fixes a plurality of clamping blocks 15. When one end of the threaded sleeve 18 is closely adjacent to the limiting ring 19, the threaded sleeve 18 stops moving, and the limiting ring 19 can seal one end of the threaded sleeve 18.

[0029] A plurality of diversion grooves are provided on the threaded sleeves 18. The diversion grooves are all arc-shaped. During use, it is convenient to divert the cold air so that the cold air flows along the axial directions of the first cable main body 11 and the second cable main body 12.

[0030] The fixing mechanism includes a limiting frame 21. A plurality of fixing grooves are provided at one ends of the first protection tube 13 and the second protection tube 14. The limiting frames 21 are slidably arranged in the fixing grooves. The limiting frames 21 are L-shaped. Tension springs 22 are arranged between the inner sides of the limiting frames 21 and one sides of the fixing grooves. One side of the limiting frame 21 is inclined. A guiding ring 23 is closely arranged at the inclined surface of the limiting frame 21, and the guiding ring 23 is fixedly arranged at one end of the threaded sleeve 18. During use, when installing the sealing ring 20, the threaded sleeve 18 is pushed to slide on the first protection tube 13 and the second protection tube 14, so that the guiding ring 23 is closely adjacent to the inclined surfaces of a plurality of limiting frames 21, and a plurality of limiting frames 21 slide in the fixing grooves. Subsequently, one side of the sealing ring 20 is closely adjacent to one side of the first fixing plate. After the sealing ring 20 is installed, the threaded sleeve 18 is pushed so that the guiding ring 23 is disengaged from the limiting frame 21. Under the action of the tension spring 22, the limiting frame 21 returns to the initial position, thereby fixing the tension spring 22.

[0031] The heat dissipation mechanism includes heat dissipation perforations 24. A number of heat dissipation perforations 24 are equidistantly arranged on the first protection tube 13 and the second protection tube 14. The cross-section of the heat dissipation perforation 24 is arc-shaped. One end of the heat dissipation perforation 24 has a larger diameter than the other end. Two heat dissipation perforations 24 on the first protection tube 13 and the second protection tube 14 combine to form a complete ventilation hole. A number of positioning columns are fixedly arranged at one end of the first protection tube 13 at equal intervals, and positioning grooves are provided at positions corresponding to the positioning columns at one end of the second protection tube 14. During use, when installing the first protection tube 13 and the second protection tube 14, the positioning columns are aligned with the positioning grooves and the positioning columns are inserted into the positioning grooves. At this time, the heat dissipation perforations 24 on the first protection tube 13 and the heat dissipation perforations 24 on the second protection tube 14 are coaxially arranged. At this time, the ventilation holes formed by the two heat dissipation perforations 24 form an arc-shaped ventilation hole with a large diameter at both ends and a small diameter in the middle. When cold air enters through one end of the ventilation hole, due to the decrease in the cross-sectional diameter in the middle of the ventilation hole, the air flow velocity in the middle increases, thereby accelerating the heat dissipation at the connection of the first cable main body 11 and the second cable main body 12.

[0032] A first sealing plate 26 is fixedly arranged inside one end of the first protection tube 13. A second sealing plate 27 is sleeved on the first sealing plate 26. The second sealing plate 27 is fixedly arranged inside one end of the second protection tube 14. During use, when one end of the first protection tube 13 and the second protection tube 14 are in close contact, the first sealing plate 26 is inserted into the second sealing plate 27, strengthening the sealing effect at the connection of the first protection tube 13 and the second protection tube 14.

[0033] Embodiment 2

[0034] The difference from Embodiment 1 is that spiral plates 25 are fixedly arranged at one end of the first protection tube 13 and the second protection tube 14. The spiral plates 25 are made of copper. During use, when one end of the first protection tube 13 and the second protection tube 14 are in close contact, the two spiral plates 25 combine to form a complete heat dissipation spiral plate, and the spiral plates 25 are made of copper, facilitating heat dissipation at the connection of the first cable main body 11 and the second cable main body 12.

[0035] A number of circular perforations are provided on the spiral plates 25. During use, it is convenient to accelerate the passage of air through the spiral plates 25, facilitating heat dissipation of the spiral plates 25.

[0036] The above embodiments disclose a cable with a protection structure. Among them, before installing the first protection tube 13 and the second protection tube 14, the threaded sleeve 18 is pushed to slide on the first protection tube 13 and the second protection tube 14, so that the guide ring 23 is in close contact with the inclined surfaces of several limiting frames 21, causing several limiting frames 21 to slide in the fixing grooves. Subsequently, one side of the sealing ring 20 is in close contact with one side of the first fixing plate. After the sealing ring 20 is installed, the threaded sleeve 18 is pushed to make the guide ring 23 disengage from the limiting frame 21. Under the action of the tension spring 22, the limiting frame 21 returns to its initial position, thereby fixing the tension spring 22. The first protection tube 13 and the second protection tube 14 are respectively sleeved on one ends of the first cable main body 11 and the second cable main body 12. Subsequently, the first cable main body 11 and the second cable main body 12 are connected. After the connection is completed, the positioning column is aligned with the positioning groove and the positioning column is inserted into the positioning groove. At this time, the heat dissipation perforations 24 on the first protection tube 13 and the heat dissipation perforations 24 on the second protection tube 14 are coaxially arranged. One ends of the first protection tube 13 and the second protection tube 14 are in close contact. Subsequently, the threaded sleeve 18 slides on the first protection tube 13 and the second protection tube 14 respectively. When one end of the threaded sleeve 18 is in close contact with the chamfer of the clamping block 15, the clamping block 15 slides in the installation groove. When the internal thread inside the threaded sleeve 18 is engaged with the external thread on the clamping block 15, the stop blocks 16 on one side of the clamping block 15 are in close contact with the first cable main body 11 and the second cable main body 12 respectively, so that the first protection tube 13 and the second protection tube 14 are respectively fixed on the first cable main body 11 and the second cable main body 12. Subsequently, the threaded sleeve 18 is rotated. Under the action of the thread, the threaded sleeve 18 fixes several clamping blocks 15. When one end of the threaded sleeve 18 is in close contact with the limiting ring 19, the threaded sleeve 18 stops moving, and the limiting ring 19 can seal one end of the threaded sleeve 18. At the same time, the first sealing plate 26 is inserted into the second sealing plate 27, enhancing the sealing effect at the connection of the first protection tube 13 and the second protection tube 14. The two spiral plates 25 are combined into a complete heat dissipation spiral plate, and the spiral plate 25 is made of copper material, facilitating heat dissipation at the connection of the first cable main body 11 and the second cable main body 12;

[0037] When in use, when cold air enters from one end of the ventilation hole, due to the reduction in the cross-sectional diameter in the middle of the ventilation hole, the air flow velocity in the middle increases, thereby accelerating heat dissipation at the connection of the first cable main body 11 and the second cable main body 12. When cold air enters from one end of the ventilation hole, due to the reduction in the cross-sectional diameter in the middle of the ventilation hole, the air flow velocity in the middle increases, thereby accelerating heat dissipation at the connection of the first cable main body 11 and the second cable main body 12.

[0038] As described above, it is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
