Description

TECHNICAL FIELD

[0001] The utility model belongs to cable protection technical field, and specifically is a cable with cable protection device. BACKGROUND

[0002] With the development of technology and the increase of power demand, the layout of cables is becoming increasingly complex. During the process of cable wiring, due to the limitation of space, for example, in some narrow wire slots, pipe or wiring space inside electrical equipment, cables often need to be bent, twisted or closely arranged. In such cases, cables, especially branch cables, are extremely susceptible to external forces and prone to shaking and displacement. The shaking and displacement of branch cables can cause a series of problems. On the one hand, shaking can cause friction between cables or between cables and objects in the surrounding environment. This friction can cause wear and tear of the outer insulation layer or sheath of the cable over time. Once the insulation layer of the cable is worn, there is a risk of electric shock, which not only affects the normal operation of the cable, but also poses a threat to the safety of surrounding equipment and personnel. On the other hand, frequent shaking can cause the cable connection part to loosen. If the cable connection part is loose, it will increase the contact resistance, which in turn can cause local heating. This local heating can accelerate the aging of the cable, and in severe cases, it can even cause a short circuit, resulting in a power failure and affecting the normal operation of the entire power system or electrical equipment.

[0003] To this end, a cable with a cable protection device is provided to solve the above problems. SUMMARY

[0030] As shown in Figures 1 to 5 A cable with a cable protection device, comprising: a branch joint device 3, a main line cable 1 vertically passing through the branch joint device 3, and branch line cables 2 respectively connected to both sides of the main line cable 1, a main line channel 4 is provided in the branch joint device 3 for the main line cable 1 to pass through, a branch line channel 5 is provided on both sides of the main line channel 4 and passes through the bottom end of the branch joint device 3, the branch line cable 2 is located in the branch line channel 5 and the bottom end extends from the bottom end of the branch line channel 5, an adjusting plate 6 is provided in the branch line channel 5 for stabilizing the branch line cable 2, and a connecting column 7 is fixedly connected on the adjusting plate 6 and longitudinally passes through the branch line channel 5 and the outer wall of the branch joint device 3.

[0031] In the specific application of the embodiment of the utility model, the main cable 1 is connected and arranged physically through the main line channel 4, and the branch cable 2 is connected and arranged physically through the branch line channel 5, so that the current can be conducted smoothly from the main cable 1 to the branch cable 2. When the power is transmitted from the main cable 1, due to the reasonable design of the internal channel of the branch joint device 3, the power can be distributed to each branch cable 2 without any obstruction according to the designed path, so as to meet the power demand of different equipment or areas.

[0032] The existence of the adjusting plate 6 in the branch line channel 5 provides lateral support force for the branch cable 2. When the branch cable 2 is shaken by external interference, the adjusting plate 6 will block the shaking and limit the movement of the branch cable 2 in the plane. At the same time, there may be a certain friction force between the adjusting plate 6 and the branch cable 2, which also helps to prevent the branch cable 2 from sliding in the channel, so as to ensure the stability. The connecting column 7 is fixedly connected with the adjusting plate 6 and the outer wall of the branch joint device 3. When external force acts on the branch joint device 3, the force is transmitted to the connecting column 7 through the outer wall of the branch joint device 3. The connecting column 7 then disperses the force to the adjusting plate 6. Since the adjusting plate 6 has a stabilizing effect on the branch cable 2 in the branch line channel 5, the whole structure can jointly bear the external force and avoid damage to the local structure. For example, when there is a pressure perpendicular to the direction of the branch joint device 3, the connecting column 7 can prevent the adjusting plate 6 from deforming due to the pressure, so as to protect the internal branch cable 2 from being affected.

[0033] In a possible implementation, the end of the connecting column 7 away from the adjusting plate 6 is connected with a top block 10, and an annular column 8 for the connecting column 7 to pass through is fixedly arranged on the branch line channel 5. The annular column 8 is rotatably connected with the connecting column 7. The main line channel 4 and the branch line channel 5 are sequentially provided with a waterproof layer 14, a fireproof layer 13 and a porcelainized silicone rubber layer 12 from inside to outside.

[0034] In the specific application of the embodiment of the utility model, the waterproof layer 14 prevents the penetration of water molecules by using the physical barrier principle according to the material properties thereof, such as low water permeability. The fireproof layer 13 resists the erosion of fire by chemical reaction or physical change when it encounters high temperature, by using the special fireproof material composition thereof. For example, some fireproof materials will decompose at high temperature, absorb heat and release non-combustible gas, so as to reduce the oxygen concentration around and inhibit the spread of fire. The porcelainization principle of the porcelainized silicone rubber layer 12 is that the composition in the silicone rubber changes at high temperature, and the inorganic composition in the silicone rubber forms a ceramic structure.

[0035] In the connection operation of the cable, the connecting post 7 transmits the force or signal of the cable to the top block 10. When the cable is subjected to tension or pressure, the connecting post 7 serves as an intermediate conducting component to transmit the force to the top block 10, and the top block 10 further transmits the force to the external component in contact therewith. In terms of signal transmission, if the cable is used to transmit an electrical signal or a data signal, the connection of the connecting post 7 and the top block 10 ensures that the signal can be stably transmitted between the cable and the external device, the principle of which is to form a good electrically-conductive contact (if it is an electrical signal) or signal coupling (if it is a data signal). The rotatable connection of the connecting post 7 and the annular post 8 is achieved by a suitable mechanical structure, such as providing a smooth surface on the contact surface of the connecting post 7 and the annular post 8 or using a ball, bearing or other component to reduce friction. When the cable needs to be rotated, the torque acting on the connecting post 7 overcomes the friction between the connecting post 7 and the annular post 8, so that the connecting post 7 can rotate relatively in the annular post 8, thereby achieving flexible adjustment of the cable while ensuring the stability of the connection.

[0036] In a possible implementation, the rotatable connection of the annular post 8 and the connecting post 7 means that an inner thread 15 is arranged on the inner wall of the annular post 8, an outer thread 15 is arranged on the connecting post 7 and matches the inner thread 15, and an insulating layer 11 is arranged at the bottom of the adjusting plate 6.

[0037] In the specific application of the embodiment of the utility model, when a torque in the circumferential direction is applied to the annular post 8, the annular post 8 will rotate upwards or downwards along the outer thread 15 of the connecting post 7 due to the helical surface contact between the inner thread 15 and the outer thread 15, and the position of the annular post 8 relative to the connecting post 7 can be accurately adjusted. For example, if it is necessary to adjust the height or angle of the cable protection device in a certain direction, the annular post 8 can be rotated to achieve this, and the adjustment amplitude can be accurately controlled according to actual needs.

[0038] During the rotation process, the cable can change its direction or angle to a certain extent along with the rotation of the annular post 8. At the same time, due to the threaded connection, the rotatable connection has a certain self-locking property, that is, after being adjusted to a suitable position, the annular post 8 will not rotate by itself due to its own gravity or external slight interference, thereby ensuring that the cable is in a stable protection state.

[0039] The insulating layer 11 is usually made of materials with high resistivity, such as rubber, plastic and the like. The electrons in these materials are tightly bound by atoms, and it is difficult for them to form free-moving charges. When the adjusting plate 6 is in the cable system, even if there is an electric field or voltage difference around, due to the existence of the insulating layer 11, the electrons cannot form a conduction current inside the insulating layer 11, thereby preventing the current from leaking from the adjusting plate 6 to the surrounding environment or flowing from the surrounding environment into the adjusting plate 6, and ensuring the electrical insulation performance of the cable system.

[0040] In one possible implementation, the branch joint device 3 is provided with an oil-free lubricated bearing at the intersection with the connecting column 7, and the branch line channels 5 are four in number and are respectively located on both sides of the main line channel 5.

[0041] In the specific application of the embodiments of the utility model, the oil-free lubricated bearing is usually made of special materials, such as self-lubricating composite materials or metal alloys with low friction coefficients. When there is relative motion or force between the branch joint device 3 and the connecting column 7 at the intersection, the material properties of the oil-free lubricated bearing play a role. The solid lubricant or low-friction material structure inside can form a lubricating film on the surface, which can effectively reduce the friction coefficient. Unlike traditional bearings that require oil lubrication, it does not need to be regularly added with lubricating oil, reducing maintenance costs and the risk of environmental pollution caused by lubricating oil leakage.

[0042] The oil-free lubricated bearing also has a certain stress dispersion capability. When the connecting column 7 is subjected to forces such as tension, pressure or torsion from the cable, the bearing can uniformly disperse these forces to the surrounding structure. For example, when the cable generates tension under the action of external forces such as wind and vibration, the tension of the connecting column 7 on the branch joint device 3 is transmitted through the oil-free lubricated bearing in a more uniform manner, avoiding local stress concentration and helping to prevent structural damage at the joint, such as material deformation, cracking, etc., ensuring the normal operation of the cable joint.

[0043] The four branch line channels 5 are located on both sides of the main line channel. During power transmission, the current in the main line is divided according to the load demand of each branch line. When current I is input into the main line, according to the size of the load resistance connected by each branch line channel, the current will automatically be distributed to each branch line channel according to Ohm's law ((I = V / R), where (V) is voltage and (R) is resistance). The branch line channel with smaller load resistance will be allocated relatively larger current, and the branch line channel with larger load resistance will be allocated relatively smaller current, thereby realizing the reasonable distribution of power among different branch lines and meeting the power demand of different electrical equipment or lines.

[0044] During the operation of the cable, the current passing through the main line and the branch lines will generate an electromagnetic field. The reasonable layout of the four branch line channels helps to optimize the distribution of the electromagnetic field and improve the electromagnetic compatibility of the cable system.

[0045] Since the branch line channels are respectively located on both sides of the main line channel, the electromagnetic fields generated by them influence and restrict each other in space. This layout can reduce the mutual interference of electromagnetic fields, reduce the influence of electromagnetic radiation on the surrounding environment and other electronic equipment, and also prevent external electromagnetic fields from interfering with the power transmission inside the cable, ensuring the stable transmission of power signals inside the cable.

[0046] It is to be noted that, in the present document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.
