Description

Technical Field

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

[0002] In the operation of modern power systems and electrical equipment, power cables play a vital role. They are the key medium for power transmission. With the continuous development of the power industry, the application environment of power cables has become increasingly complex and diverse, from traditional overhead and underground installations to various special environments such as oceans, mines, and chemical companies. At the same time, the power system has increasingly higher requirements for the reliability, safety, and stability of power supply.

[0003] In many cases, power cables are subject to various mechanical forces. For example, in urban construction, underground cables may be squeezed, collided, and scraped due to road construction, excavation, and other activities, causing problems such as outer sheath wear and internal core deformation.

[0004] In cables where two sections of cables are connected, a protective sheath is directly attached to the outside of the two sections of power cables at the connection point, and a rubber sheath is set on the outer wall of the cable to achieve multiple protections. The outer sheath of the cable has limited protection capabilities and is often unable to withstand these complex and changeable mechanical forces for a long time. Once the outer sheath is damaged, it will directly impact the two sections of the cable, which will expose the internal insulation layer and core wire to a dangerous environment, increasing the risk of cable failure. Utility Model Content

[0005] The purpose of the present utility model is to provide an electric power cable with a multiple protection structure to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model provides an electric power cable with a multiple protection structure, including a cable body, an outer wall of the cable body is fixedly installed with a mounting ring, the outer wall of the cable body is sleeved with a second sleeve, the outer wall of the second sleeve is provided with a thread, the outer wall of the second sleeve is threadedly connected to the first sleeve, the outer wall of the first sleeve is rotatably connected to a plurality of connecting rods, the end of the connecting rod away from the first sleeve is connected to a mounting bar, one end of the mounting bar is fixedly installed with a connecting block, the end of the connecting block away from the mounting bar is fixedly installed with a blocking block, the outer wall of the mounting ring is fixedly installed with a mounting frame, the mounting frame is sleeved on the outside of the connecting block, and the outside of the mounting bar is provided with a galvanized steel pipe.

[0007] Furthermore, the shape of the installation bar is set to be L-shaped, and a rubber layer is fixedly installed on the top of the installation bar, and the top of the rubber layer abuts against the inner wall of the galvanized steel pipe.

[0008] Furthermore, a waterproof layer is provided on the outer wall of the cable body, a battery core is provided inside the cable body, and a protective layer is provided between the cable body and the battery core.

[0009] Furthermore, the installation frames are evenly distributed on the outer wall of the installation ring, and the multiple installation frames are distributed in a cross shape.

[0010] Furthermore, a polyvinyl chloride layer is fixedly installed on the outer wall of the galvanized steel pipe, and an armor layer is fixedly installed on the outer wall of the polyvinyl chloride layer.

[0011] Furthermore, the outer wall of the first sleeve is coated with a waterproof coating, and the outer wall of the armor layer is provided with an anti-corrosion coating.

[0012] Furthermore, the shape of the installation frame is set to be a U-shape, and the installation ring, the installation frame, the first sleeve and the second sleeve are all set to be made of steel.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In the present invention, a worker rotates the second sleeve, which is threadedly connected to the first sleeve, to move the first sleeve toward the mounting frame. The bottom end of the connecting rod is fixed on the first sleeve, increasing the angle between it and the first sleeve while maintaining its position. The top end of the connecting rod supports the mounting bar, and the rubber layer on the top of the mounting bar abuts the inner wall of the galvanized steel pipe to support and fix the galvanized steel pipe. The galvanized steel pipe, PVC, and armor layer constitute the first layer of protection. The isolation space formed by the connecting rod and the mounting bar is the second layer of protection. The first and second sleeves are the third layer of protection. This multi-layered protection structure can withstand more types of impacts at the connection between the two cable sections, providing more comprehensive protection and a higher upper limit of protection.

[0015] 2. In this utility model, the PVC layer protects the galvanized steel pipe from wear and tear due to contact with the outside world. It also provides a buffer during installation, reducing friction with other objects and preventing structural changes in the steel pipe due to wear, thereby securing the cable in place. The armor layer, located on the outer surface of the PVC layer, forms a multi-layered protective structure with the galvanized steel pipe, increasing the mechanical strength of the cable. When subjected to significant impact or compression forces, the armor layer first absorbs and distributes some of the force to the PVC layer and galvanized steel pipe, minimizing cable displacement and enhancing securement.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1-4 , the utility model provides a technical solution:

[0023] See Figures 1-4 The figure shows an electric power cable with a multiple protection structure, comprising a cable body 1, a mounting ring 2 fixedly mounted on the outer wall of the cable body 1, a second sleeve 4 sleeved on the outer wall of the cable body 1, a thread provided on the outer wall of the second sleeve 4, a first sleeve 3 threadedly connected to the outer wall of the second sleeve 4, a plurality of connecting rods 5 rotatably connected to the outer wall of the first sleeve 3, a mounting bar 6 connected to one end of the connecting rod 5 away from the first sleeve 3, a connecting block 8 fixedly mounted on one end of the mounting bar 6, a blocking block 9 fixedly mounted on the end of the connecting block 8 away from the mounting bar 6, a mounting frame 7 fixedly mounted on the outer wall of the mounting ring 2, the mounting frame 7 sleeved on the outside of the connecting block 8, and a galvanized steel pipe 11 provided on the outside of the mounting bar 6.

[0024] When the staff rotates the second sleeve 4, the first sleeve 3 is threadedly connected to the second sleeve 4, so the first sleeve 3 moves toward the mounting frame 7, and the bottom end of the connecting rod 5 is set on the first sleeve 3 as a fixed point, which is rotated upward, but the position remains unchanged. The angle between the connecting rod 5 and the first sleeve 3 becomes larger, and the top of the connecting rod 5 is rotatably connected to the mounting bar 6. The top of the connecting rod 5 lifts the mounting bar 6, and the rubber layer 10 on the top of the mounting bar 6 abuts against the inner wall of the galvanized steel pipe 11, which supports and fixes the galvanized steel pipe 11. The galvanized steel pipe 11, polyvinyl chloride 12, and armor layer 13 can serve as the first layer of protection to the outside world. The connecting rod 5 and the mounting bar 6 create a part of the isolation space between the galvanized steel pipe 11 and the cable body 1, which serves as the second layer of protection. The first sleeve 3 and the second sleeve 4 are arranged on the outside of the cable body 1 to serve as the third layer of protection. This multi-layer protection structure can cope with more types of impacts, provide more comprehensive protection, and the upper limit of protection will be higher.

[0025] At the same time, the connecting block 8 moves upwards at the opening on the installation frame 7. The cross section of the blocking block 9 is larger than the opening on the installation frame 7, so the blocking block 9 can play a role of limiting.

[0026] See Figure 1-3 The shape of the mounting block 6 is set to be L-shaped, and a rubber layer 10 is fixedly installed on the top of the mounting block 6. The top of the rubber layer 10 abuts against the inner wall of the galvanized steel pipe 11.

[0027] The close contact between the rubber layer 10 and the inner wall of the galvanized steel pipe 11 can ensure that the position of the cable is more stable. This close fit enables the cable and the mounting strip 6 to form a whole with the galvanized steel pipe 11, reducing the activity space of the cable in the galvanized steel pipe 11. For example, in the case of temperature changes or environmental vibrations, the cable will not gradually deviate from the original fixed position due to slight displacements, thereby ensuring the long-term stability of the fixation.

[0028] See Figure 1-2 The outer wall of the cable body 1 is provided with a waterproof layer, the inside of the cable body 1 is provided with a battery core 15, and a protective layer 14 is provided between the cable body 1 and the battery core 15.

[0029] The waterproof layer material itself has a certain degree of toughness and strength, such as chlorinated polyethylene. When the cable is subjected to external forces, the waterproof layer can serve as a line of defense, resisting some of the external forces and reducing deformation of the cable body 1. This helps maintain the integrity of the cable's internal structure, including the stable position of the protective layer 14 and the battery cell 15, thereby enhancing the stability of the cable after it is fixed.

[0030] See Figure 1-3 The mounting frames 7 are evenly distributed on the outer wall of the mounting ring 2 , and the plurality of mounting frames 7 are distributed in a cross shape.

[0031] The cross-shaped mounting frames 7 provide balanced support against external forces from various directions. Since they are distributed around the mounting ring 2, no matter which direction the external force is applied, the corresponding mounting frame 7 will resist it, ensuring stable support for the cable in all directions. Like a stable cross-shaped bracket, it effectively prevents the cable from tilting, shaking, and other instabilities during installation or use.

[0032] See Figure 1-2 The outer wall of the galvanized steel pipe 11 is fixedly installed with polyvinyl chloride 12, and the outer wall of the polyvinyl chloride 12 is fixedly installed with an armor layer 13.

[0033] PVC 12 prevents direct contact between the galvanized steel pipe 11 and external objects, thus protecting it from wear and tear due to friction. During installation, when routing cables through pipes or bridges, PVC 12 acts as a buffer, reducing friction between the pipe and other objects. It also helps prevent structural changes in the pipe due to localized wear, ensuring that the cable remains securely in place within the pipe.

[0034] The armor layer 13 is fixed to the outer wall of the PVC 12, forming a multi-layer protective structure. This structure can increase the overall mechanical strength of the cable. When a large external impact or extrusion force is applied, the armor layer 13 can first withstand the force and disperse part of the force to the PVC 12 and galvanized steel pipe 11. This multi-layered synergistic resistance can effectively reduce cable displacement and enhance fixed stability.

[0035] See Figure 1 The outer wall of the first sleeve 3 is coated with a waterproof coating, and the outer wall of the armor layer 13 is provided with an anti-corrosion coating.

[0036] An anti-corrosion coating is applied to the outer surface of the armor layer 13 to protect it from external corrosive substances such as chemical gases and acid rain. Corrosion of the armor layer 13 reduces its mechanical strength, potentially preventing it from effectively protecting the cable's internal structure when subjected to external forces. The anti-corrosion coating extends the service life of the armor layer 13 and maintains its excellent mechanical properties, ensuring that it can stably perform its protective and support functions when subjected to external forces such as impact and compression, maintaining the cable's fixed position.

[0037] See Figure 1 The shape of the mounting frame 7 is set to be a U-shape, and the mounting ring 2, the mounting frame 7, the first sleeve 3, and the second sleeve 4 are all set to be made of steel.

[0038] Steel has high strength and hardness, capable of withstanding significant external forces. The mounting ring 2 and mounting frame 7 serve as the cable's external fixing framework, and their high strength effectively resists external pressure, tension, and impact. For example, in an industrial environment, if a heavy object accidentally falls on the cable or the cable is struck by a vehicle, the steel mounting frame 7 protects the cable from deformation or displacement due to excessive external forces.

[0039] Working principle: The staff rotates the second sleeve 4, and the first sleeve 3 is threadedly connected to the second sleeve 4, so that the first sleeve 3 moves toward the mounting frame 7, and the bottom end of the connecting rod 5 is set on the first sleeve 3 as a fixed point, which rotates upward, but the position remains unchanged. The angle between the connecting rod 5 and the first sleeve 3 becomes larger, and the top of the connecting rod 5 is rotatably connected to the mounting bar 6. The top of the connecting rod 5 lifts the mounting bar 6, and the rubber layer 10 on the top of the mounting bar 6 abuts against the inner wall of the galvanized steel pipe 11, which supports and fixes the galvanized steel pipe 11. The galvanized steel pipe 11, polyvinyl chloride 12, and armor layer 13 can serve as the first layer of protection to the outside world. The connecting rod 5 and the mounting bar 6 create a part of the isolation space between the galvanized steel pipe 11 and the cable body 1, which serves as the second layer of protection. The first sleeve 3 and the second sleeve 4 are arranged on the outside of the cable body 1 to serve as the third layer of protection. This multi-layer protection structure can cope with more types of impacts at the connection between the two cable sections, provide more comprehensive protection, and the upper limit of protection will be higher.

[0040] At the same time, the connecting block 8 moves upwards at the opening on the installation frame 7. The cross section of the blocking block 9 is larger than the opening on the installation frame 7, so the blocking block 9 can play a role of limiting.

[0041] The above structure is ideally placed at the connection point between two cables or at a location that specifically requires protection.

[0042] PVC 12 prevents direct contact between the galvanized steel pipe 11 and external objects, thus protecting it from wear and tear due to friction. During installation, when routing cables through pipes or bridges, PVC 12 acts as a buffer, reducing friction between the pipe and other objects. It also helps prevent structural changes in the pipe due to localized wear, ensuring that the cable remains securely in place within the pipe.

[0043] The armor layer 13 is fixed to the outer wall of the PVC 12, forming a multi-layer protective structure. This structure can increase the overall mechanical strength of the cable. When a large external impact or extrusion force is applied, the armor layer 13 can first withstand the force and disperse part of the force to the PVC 12 and galvanized steel pipe 11. This multi-layered synergistic resistance can effectively reduce cable displacement and enhance fixed stability.
