Description

Technical Field

[0001] The invention relates to the technical field of cables, in particular to a cable structure for preventing current deviation by connecting multiple cables in parallel. Background Art

[0002] A cable is an electrical energy or signal transmission device, usually composed of one or several conductors. In actual power transmission scenarios, if the current carrying capacity of a single cable cannot meet the requirements, it will easily cause the cable to overheat, and in severe cases may cause insulation breakdown and other faults. Therefore, people usually use multiple cables in parallel to solve this problem. However, when multiple cables are connected in parallel, current deviation often occurs. At this time, in order to ensure the stability and safety of power transmission, people will use multiple cables in parallel to prevent current deviation cable structure.

[0003] When in use, the existing multi-cable parallel anti-current flow cable can ensure that each parallel branch cable can transmit current or signal evenly, thereby improving the stability and reliability of the entire system. However, it is not convenient to carry out overhead installation with the suspension line during long-distance overhead laying. That is, when multiple cables parallel anti-current flow cables are carried out for long-distance overhead laying, construction workers generally need to lay the cables overhead first, and then use climbing equipment to continuously move along the cable laying path to evenly distribute and install the prepared installation hooks on the suspension line. However, it is difficult for construction workers to accurately control the spacing between each hook during the movement, and uneven distribution of hooks is likely to occur, which can easily lead to uneven force on the cables, thereby affecting the service life of the cables, reducing the use effect of the multi-cable parallel anti-current flow cable, and also reducing the use efficiency of the multi-cable parallel anti-current flow cable.

[0004] Therefore, we propose a multi-cable parallel anti-current cable structure to solve the problems raised in the above background technology. Summary of the invention

Under the action of the separator, the cable body can buffer the effects of vibration, external impact, or volume expansion and contraction due to temperature changes, and prevent the conductors from being displaced or damaged due to mutual extrusion or collision. Under the action of the cylindrical hole, the filling layers between the grooves of the separator can be connected together, thereby increasing the mechanical stability of the internal structure of the entire cable body. Under the action of the protective layer, the cable body can absorb and disperse the external forces when it is subjected to external forces such as vibration, tension or extrusion, thereby protecting the steel wire core from damage. Under the action of the steel wire core, the cable body can effectively resist the tensile force when it is subjected to tensile force during laying, thereby preventing the cable body from being broken or over-stretched.

[0025] Embodiment 2: According to Figure 1-Figure 3 and Figure 8 As shown, the cable body 1 includes a steel wire core 101, a protective layer 102 is provided on the outer surface of the steel wire core 101, a partition 103 is provided on the outer wall of the protective layer 102, a plurality of cylindrical holes 104 are opened on the surface of the partition 103, a fixing sleeve 105 is provided between the outer surfaces of the partition 103, an insulating layer 107 is provided inside the four grooves of the partition 103, a conductor 106 is provided inside each insulating layer 107, a filling layer 108 is provided between the fixing sleeve 105 and the partition 103, an inner lining layer 109 is provided on the outer wall of the fixing sleeve 105, a heat-resistant layer 110 is provided on the outer wall of the inner lining layer 109, a waterproof layer 111 is provided on the outer wall of the heat-resistant layer 110, a metal shielding layer 112 is provided on the outer wall of the waterproof layer 111, and an outer sheath layer 113 is provided on the outer wall of the metal shielding layer 112.

[0026] In this embodiment, when the cable body 1 needs to be used near a chemical plant or a sewage treatment plant, various chemical corrosion sources are likely to exist in the surrounding environment. At this time, the outer sheath layer 113 can prevent these chemical substances from corroding the internal structure of the cable body 1, thereby extending the service life of the cable body 1. When various electromagnetic interference sources exist in the surrounding environment of the cable body 1, the metal shielding layer 112 can offset the external high-frequency interference electromagnetic field, thereby protecting the signal transmission inside the cable body 1. When the cable body 1 is used in an environment with high humidity, the waterproof layer 111 can prevent water vapor from condensing on the surface of the cable body 1 and penetrating into the interior, affecting the cable body. The service life of the cable body 1 is extended. When an electrical fault (such as a short circuit or lightning strike) occurs in the cable body 1 and an arc is generated, the heat-resistant layer 110 can enable the cable body 1 to withstand the high temperature of the arc without being damaged. When the cable body 1 is impacted by an external force (such as being blown by the wind and hitting the pole tower), the lining layer 109 can absorb the impact energy and protect the internal structure of the cable body 1. When the cable body 1 is used in the outdoor environment for a long time, the filling layer 108 can reduce the occurrence of aging or degradation problems, and can maintain its performance for a long time, providing stable filling and protection for the cable body 1. When the cable body 1 is in use, the insulating layer 107 can be used to maintain The invention can ensure that the electrical performance of each conductor 106 is independent, reduce the capacitive coupling and electromagnetic interference between the conductors 106, thereby improving the transmission efficiency and quality of the cable body 1. When the cable body 1 is in use, the loss of electric energy in the transmission process can be effectively reduced under the action of the conductor 106. When the cable body 1 is subjected to vibration or uneven force during installation, the fixing sleeve 105 can absorb and disperse these forces to protect the cable body 1 and the separator 103 from damage. When the cable body 1 is subjected to vibration, external force impact or volume expansion and contraction due to temperature changes during operation, the separator 103 can buffer these influences and prevent the conductor from being damaged. The bodies 106 are displaced or damaged due to mutual squeezing or collision. The filling layers 108 between the grooves of the separator 103 can be connected together under the action of the cylindrical hole 104, thereby increasing the mechanical stability of the internal structure of the entire cable body 1. When the cable body 1 is subjected to external forces such as vibration, tension or squeezing, these external forces can be absorbed and dispersed under the action of the protective layer 102, thereby protecting the steel wire core 101 from damage. When the cable body 1 is subjected to tensile force during the laying process (such as the weight of the cable itself and the possible wind load tension during overhead laying), the steel wire core 101 can effectively resist this tension to prevent the cable body 1 from being broken or over-stretched.

[0027] The effect and working principle achieved by the entire mechanism are as follows: when it is necessary to connect multiple cables in parallel with the anti-bias current cable and the suspension line for overhead installation, the sealing plug 219 is first removed, and then the outlet end of the prepared inflatable ball is connected to the inlet end of the three-way pipe 218, and then the connected inflatable ball is manually pressed. At this time, the pressed inflatable ball will begin to continuously inflate the interior of the three-way pipe 218, and the gas that continuously enters the interior of the three-way pipe 218 will enter the interiors of the two circular tubes 217 respectively, and then enter the interiors of the two rectangular grooves 215 respectively. At this time, the gas that continuously enters the interiors of the two rectangular grooves 215 will be driven by the cooperation of the shell 206, the corresponding block 210, the corresponding first annular groove 211, the corresponding first sealing ring 212, the corresponding second annular groove 213 and the corresponding second sealing ring 214, respectively. The two sliders 209 are moved toward each other (at this time, they enter the two rectangular grooves 215) The gas in the upper and lower parts will enter the space formed by the corresponding slider 209, the corresponding block 210 and the shell 206), and the two sliders 209 moving towards each other will compress the spring 216 under the cooperation of the shell 206, and at the same time, the two sliders 209 moving towards each other will respectively drive the two blocks 210 to move towards each other. When the connecting ends of the two blocks 210 are separated from the corresponding slots 220, the pressing of the inflatable ball is stopped first, and then a force is applied to the U-shaped rod 207 by the cooperation of the hole block 208, so that the U-shaped rod 207 moves away from the three-way pipe 218 until the U-shaped rod 207 is separated from the second arc block 204, and then the second arc block 204 is removed from the inside of the annular groove 201, and then the removed second arc block 204 is moved until the end faces of the two ends of the second arc block 204 are in contact with the front surface and the rear surface of the rectangular block 202 respectively (such as Figure 2As shown), at the same time, the second arc block 204 is sleeved on the outer surface of the suspension line, and then the U-shaped rod 207 is reset and moved by using the cooperation of the hole block 208. When the U-shaped rod 207 is reset to its original position, the movement of the U-shaped rod 207 is stopped first, and then the flushing ball is separated from the three-way pipe 218. At this time, the two sliders 209 will be reset and moved in cooperation with the shell 206 and the rebound force of the spring 216, and the two sliders 209 that are reset will drive the corresponding block 210 to move. At the same time, the two sliders 209 that are reset will discharge the gas in cooperation with the corresponding block 210, the shell 206, the corresponding round tube 217 and the three-way pipe 218. When the clamping ends of the two clamping blocks 210 are respectively movable, the clamping ends are respectively movable. The second arc block 204 is connected to the inside of the two card slots 220. At this time, the second arc block 204 can be connected to the rectangular block 202 with the cooperation of the two placement grooves 205, the U-shaped rod 207, the two card blocks 210 and the two card slots 220. At the same time, the second arc block 204 can be connected to the cable body 1 with the cooperation of the rectangular block 202, the annular groove 201 and the two first arc blocks 203. Then, the sealing plug 219 is reset to its original position, and then the above-mentioned operation steps are followed to install the remaining installation mechanisms 2 on the cable body 1 with the suspension wire. When the cable body 1 needs to be used near a chemical plant or a sewage treatment plant, various chemical corrosion sources are likely to exist in its surrounding environment. At this time, the outer sheath layer 113 can be used to prevent The invention prevents these chemicals from corroding the internal structure of the cable body 1, thereby extending the service life of the cable body 1. When there are various electromagnetic interference sources in the surrounding environment of the cable body 1, the metal shielding layer 112 can offset the external high-frequency interference electromagnetic field, thereby protecting the signal transmission inside the cable body 1. When the cable body 1 is used in an environment with high humidity, the waterproof layer 111 can prevent water vapor from condensing on the surface of the cable body 1 and penetrating into the interior thereof, thereby affecting the service life of the cable body 1. When an electrical fault (such as a short circuit or a lightning strike) occurs in the cable body 1 and an arc is generated, the heat-resistant layer 110 can be used to enable the cable body 1 to withstand the high temperature of the arc without being damaged. When the cable body 1 is impacted by an external force, the heat-resistant layer 110 can prevent the cable body 1 from condensing on the surface of the cable body 1 and penetrating into the interior thereof, thereby affecting the service life of the cable body 1. When the cable body 1 is blown by the wind and hits the pole tower, the inner lining layer 109 can absorb the impact energy and protect the internal structure of the cable body 1. When the cable body 1 is used under long-term outdoor exposure, the filling layer 108 can reduce the occurrence of aging or degradation problems, and can maintain its performance for a long time, providing stable filling and protection for the cable body 1. When the cable body 1 is in use, the insulating layer 107 can ensure the independence of the electrical performance of each conductor 106, reduce the capacitive coupling and electromagnetic interference between the conductors 106, thereby improving the transmission efficiency and quality of the cable body 1. When the cable body 1 is in use, the conductor 106 can effectively reduce the loss of electric energy during transmission.When the cable body 1 is subjected to vibration or uneven force during installation, the fixing sleeve 105 can absorb and disperse these forces to protect the cable body 1 and the separator 103 from damage. When the cable body 1 is subjected to vibration, external force impact or volume expansion and contraction due to temperature changes during operation, the separator 103 can buffer these effects and prevent the conductors 106 from being displaced or damaged due to mutual extrusion or collision. The cylindrical holes 104 can make the separators 103 The filling layers 108 between the grooves are connected together, thereby increasing the mechanical stability of the internal structure of the entire cable body 1. When the cable body 1 is subjected to external forces such as vibration, tension or extrusion, the protective layer 102 can absorb and disperse these external forces, thereby protecting the steel wire core 101 from damage. When the cable body 1 is subjected to tensile force during the laying process (such as the gravity of the cable itself and the possible wind load tension during overhead laying), the steel wire core 101 can effectively resist this tension and prevent the cable body 1 from being broken or over-stretched.

[0028] The second arc block 204 can be bent and deformed.

[0029] Among them, Figure 1 The cable body 1 shown is a part of the entire cable, and a plurality of mounting mechanisms 2 are evenly distributed on the entire cable.

[0030] Among them, the outer sheath layer 113 is made of polyvinyl chloride material, the metal shielding layer 112 is made of aluminum foil material, the waterproof layer 111 is made of asphalt waterproof coating, the heat-resistant layer 110 is made of mica tape material, the inner lining layer 109 is made of polyolefin elastomer material, the filling layer 108 is made of glass fiber filling material, the insulating layer 107 is made of ethylene propylene rubber material, the conductor 106 is made of copper material, the fixing sleeve 105 is made of rubber material, the separator 103 is made of silicone rubber material, the protective layer 102 is made of rubber material, and the steel wire core 101 is made of high carbon steel wire material.

[0031] Among them, the inflatable ball mentioned above is similar to the inflatable ball on the sphygmomanometer, and the air inlet port and the air outlet port of the inflatable ball are both installed with one-way valves. When the inflatable ball is not pressed, the pressure inside the ball is lower than the external atmospheric pressure. Under the action of the air pressure difference, the external air will push open one of the one-way valves and enter the ball. When the inflatable ball is pressed by hand, the air inside the ball is compressed and the pressure increases. At this time, the air in the inflatable ball will pass through the other one-way valve and enter the interior of the three-way pipe 218.
