Description

Technical Field

[0001] This invention relates to the field of cable fixing technology, and in particular to a cable sheath tube that can fix cables and its application. Background Technology

[0002] A cable is an electrical circuit used to transmit electrical energy, signals, or realize electromagnetic energy conversion. It is usually composed of one or more mutually insulated conductors and an outer insulating protective layer. Cables are widely used in many fields such as modern industry, communications, construction, and transportation. In power systems, cables are used to transmit high-voltage electrical energy, connect power plants, substations, and user terminals, and ensure the efficient transmission of electrical energy. When laying out power lines, cables usually need to be fixed to racks. Currently, common cable fixing methods mainly include using clip-on structures or cable ties for fixing.

[0003] However, at cable joints, due to their relatively weak structure, when using clip-on structures or cable ties for fixation, the cable joints are often directly exposed to the outside without corresponding protective structures. This makes the cable joints susceptible to external mechanical damage, environmental corrosion, and other damage, thereby affecting the cable's service life and transmission performance, and increasing the risk of cable damage.

[0004] To address the aforementioned issues, this application proposes a device for fixing cables and a cable sheath tube for its application. Summary of the Invention

[0005] This invention proposes a cable sheath tube for fixing cables and its application, which solves the problems in related technologies where cable connections are exposed to the outside when fixed with clips or cable ties, lacking protection, and susceptible to mechanical damage and environmental corrosion, affecting service life and transmission performance, and increasing the risk of damage.

[0006] The present invention proposes a device for fixing cables, including a fixing tube;

[0007] The fixed tube has multiple opening slots arranged along its length. Each opening slot is equipped with a U-shaped shell, and each U-shaped shell is hinged with a V-shaped limiting member. A clamping area for clamping cables is formed between the multiple V-shaped limiting members. A bladder-type assembly that supports the middle of the V-shaped limiting member is installed inside the U-shaped shell. The bladder-type assembly is filled with inert gas.

[0008] Both ends of the fixed tube are equipped with sealing bladders, and the sealing bladders at both ends are respectively connected to multiple bladder-type components. When the cable passes through the fixed tube and the cable connection is in the clamping area, the sealing bladder is inflated, allowing the gas to enter the bladder-type component. The outward movement of the bladder-type component causes the V-shaped limiting component to deform and support and clamp the cable. The sealing bladder expands to seal the end of the fixed tube and clamp the cable tightly.

[0009] As a further optimization of the present invention, the V-shaped limiting member includes two limiting rods, with one end of the two limiting rods hinged together and the other end of the two limiting rods rotatably connected to both ends inside the U-shaped shell. The two limiting rods form a V-shaped structure, and the bladder-type component is used to support the connection between the two limiting rods.

[0010] As a further optimization of the present invention, multiple spaced rubber pads are connected to the outer sides of both limiting rods.

[0011] As a further optimization of the present invention, the bladder assembly includes a hollow block, a top bladder portion, and an elastic push portion. The hollow block is installed in the middle of the U-shaped shell. An insertion cavity communicating with the sealing bladder is opened in the hollow block. The elastic push portion is installed in the insertion cavity. The top bladder portion is inserted into the insertion cavity and connected to the elastic push portion. The top bladder portion supports the hinge joint of the two limiting rods. Inert gas is filled in the top bladder portion.

[0012] As a further optimization of the present invention, the elastic push part includes a spring and a piston plate. The piston plate is installed in the cavity of the hollow block by means of the spring, and the piston plate slides in fit with the inner wall of the hollow block. The top bladder part is installed on the side of the piston plate away from the spring.

[0013] As a further optimization of the present invention, the top bladder includes a bladder block and a top bladder body. The bladder block is fixed on the side of the piston plate away from the spring. The top bladder body is connected to the bladder block to support the hinge joint of the two limiting rods. The inert gas is nitrogen, which is filled in the bladder block and the top bladder body.

[0014] As a further optimization of the present invention, the sealing bladder includes a ring, an annular sealing part and an air guide tube. Both ends of the fixed tube are equipped with rings, and an annular sealing part is installed inside the ring. Multiple air guide tubes are connected to the annular sealing part, and the multiple air guide tubes are respectively connected to the insertion cavities in multiple hollow blocks.

[0015] As a further optimization of the present invention, the annular sealing part includes an annular bladder, the annular bladder is fixed inside a ring, the air guide tube is connected to the outer periphery of the annular sealing part, and an air intake valve is connected to the outer side of the annular bladder.

[0016] As a further optimization of the present invention, a plurality of annular liners arranged at intervals are fixed inside the annular bladder.

[0017] A cable sheath tube for fixing cables is provided for use in the aforementioned cable fixing device. The cable sheath tube body is included, and the cable fixing device is installed inside the cable sheath tube body for fixing cables.

[0018] The above-described technical solution of the present invention has the following beneficial technical effects:

[0019] 1. This invention involves passing one section of cable through a fixed tube, then connecting another section of cable to the first section outside the fixed tube. The connected cable is then moved so that its connection point is inside the fixed tube, positioned within a clamping area between multiple V-shaped limiting members. An inflation device then inflates the sealing bladders at both ends of the fixed tube. The gas enters the hollow block within the bladder assembly, pushing the elastic pusher outwards, causing the top bladder to support the V-shaped limiting members. The V-shaped limiting members deform and support the cable, clamping it between the multiple V-shaped limiting members. After inflation, the sealing bladders fit tightly against the cable, further clamping it and preventing dust from entering the fixed tube. This design, through the synergistic effect of the fixed tube, V-shaped limiting members, bladder assembly, and sealing bladders, effectively clamps the cable, preventing external mechanical damage and environmental corrosion. Simultaneously, the inflated sealing bladders prevent dust from entering the fixed tube, thereby extending the cable's service life and reducing the risk of cable damage.

[0020] 2. The present invention fills the top bladder with inert gas. When the cable is carrying high voltage electricity and the load is too large, causing it to burn, the flames will cause the top bladder to rupture. After the top bladder ruptures, the inert gas inside will be discharged, extinguishing the fire at the cable connection point, effectively preventing the fire from spreading, further improving the safety of the cable connection point, and reducing the risk of cable damage caused by fire.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0031] Example 1

[0032] like Figure 1-8 As shown, the present invention proposes a device for fixing cables, including a fixing tube 1;

[0033] The fixed tube 1 has multiple opening slots arranged along its length. Each opening slot is equipped with a U-shaped shell 11. Each U-shaped shell 11 is hinged with a V-shaped limiting member 2. A clamping area for clamping the cable is formed between the multiple V-shaped limiting members 2. A bladder-type component 3 that supports the middle of the V-shaped limiting member 2 is installed inside the U-shaped shell 11. The bladder-type component 3 is filled with inert gas.

[0034] Both ends of the fixed tube 1 are equipped with sealing bladders 4, and the sealing bladders 4 at both ends are respectively connected to multiple bladder-type components 3. When the cable passes through the fixed tube 1 and the cable connection is in the clamping area, the sealing bladders 4 are inflated, so that the gas enters the bladder-type components 3. The outward movement of the bladder-type components 3 drives the V-shaped limiting member 2 to deform and support and clamp the cable. The sealing bladders 4 expand to seal the end of the fixed tube 1 and clamp the cable tightly.

[0035] This invention involves passing one cable through a fixed tube 1, and then connecting another cable to the first cable on the outside of the fixed tube 1. The connected cable is then moved so that its connection point is inside the fixed tube 1, in the clamping area between multiple V-shaped limiting members 2. Subsequently, the sealing bladders 4 at both ends of the fixed tube 1 are inflated using an inflation device. The gas enters all the bladder components 3 through the connecting channel, causing the components inside the bladder components 3 to move outward. The bladder components 3 apply a supporting force to the middle of the V-shaped limiting members 2, forcing the V-shaped limiting members 2 to undergo elastic deformation, thus clamping the cable between the V-shaped limiting members 2. At the same time, the sealing bladders 4 expand after inflation, tightly adhering to the outer periphery of the cable, thus completing both the sealing protection of the end of the fixed tube 1 and forming a secondary clamping, providing double protection for the stability of the cable fixation and preventing cable movement.

[0036] In this embodiment, the V-shaped limiting member 2 includes two limiting rods 21. The two limiting rods 21 are hinged at adjacent ends, and the ends of the two limiting rods 21 that are far apart are rotatably connected to the two ends inside the U-shaped shell 11. The two limiting rods 21 form a V-shaped structure. The capsule-type component 3 is used to support the connection point of the two limiting rods 21. When the capsule-type component 3 applies a supporting force to the hinge point of the two limiting rods 21, the hinge point is forced to move outward, causing the two limiting rods 21 to rotate around their respective connection points with the U-shaped shell 11. The opening angle of the V-shaped structure is reduced, and the inner sides of the two limiting rods 21 move towards the cable direction and fit together synchronously. This structural design concentrates the clamping force on the cable surface, and through the rotational characteristics of the two-point hinge, it ensures that the limiting rods 21 can adapt to cables of different diameters, achieving adaptive clamping, while dispersing the clamping pressure and avoiding excessive local pressure that could damage the cable sheath.

[0037] In this embodiment, multiple spaced rubber pads 22 are connected to the outer sides of both limiting rods 21. When the V-shaped limiting member 2 clamps the cable, the rubber pads 22 are in direct contact with the cable sheath. The rubber material itself has good elasticity and friction. On the one hand, it can increase the friction between the limiting rod 21 and the cable, effectively preventing the cable from sliding after clamping. On the other hand, the elastic deformation of the rubber pads 22 can buffer the pressure generated during clamping, preventing the hard limiting rod 21 from directly squeezing the cable sheath and protecting the cable insulation layer from damage.

[0038] In this embodiment, the capsule assembly 3 includes a hollow block 31, a top capsule 32, and an elastic pusher 33. The hollow block 31 is installed in the middle of the U-shaped shell 11. The hollow block 31 has an insertion cavity that communicates with the sealing capsule 4. The elastic pusher 33 is installed in the insertion cavity. The top capsule 32 is inserted into the insertion cavity and connected to the elastic pusher 33. The top capsule 32 supports the hinge of the two limiting rods 21. Inert gas is filled in the top capsule 32. When the sealing capsule 4 is inflated, the gas enters the insertion cavity of the hollow block 31, pushes the elastic pusher 33 outward, and then drives the top capsule 32 out of the insertion cavity, acting on the hinge of the two limiting rods 21 to provide support and ensure that the V-shaped limiting member 2 can maintain a stable clamping state.

[0039] In this embodiment, the elastic push part 33 includes a spring 331 and a piston plate 332. The piston plate 332 is installed in the cavity of the hollow block 31 through the spring 331, and the piston plate 332 slides with the inner wall of the hollow block 31. The top bladder 32 is installed on the side of the piston plate 332 away from the spring 331. When gas enters the cavity, the gas pressure acts on the piston plate 332, overcoming the elastic force of the spring 331 and pushing the piston plate 332 to slide outward of the cavity. This causes the top bladder 32 to move towards the hinge of the V-shaped limiting member 2 and apply a supporting force. The elastic characteristics of the spring 331 give the movement of the piston plate 332 a buffering effect, preventing the supporting force from being too large at any moment and damaging the V-shaped limiting member 2 or the cable. At the same time, when the cable needs to be disassembled later, the gas in the sealing bladder 4 is released, and the rebound force of the spring 331 can drive the piston plate 332 to reset, causing the top bladder 32 to retract into the cavity, and the V-shaped limiting member 2 to return to its initial state, making it convenient to remove the cable.

[0040] In this embodiment, the top bladder 32 includes a bladder block 321 and a top bladder body 322. The bladder block 321 is fixed on the side of the piston plate 332 away from the spring 331. The top bladder body 322 is connected to the bladder block 321 to support the hinge joint of the two limiting rods 21. The inert gas is nitrogen, which is filled in the bladder block 321 and the top bladder body 322. When the piston plate 332 moves outward, it drives the bladder block 321 and the top bladder body 322 to move outward synchronously. The top bladder body 322 applies a supporting force to the hinge joint of the two limiting rods 21 to ensure that the V-shaped limiting member 2 deforms stably to clamp the cable. In addition, when the cable burns due to overload, the flame will destroy the structure of the top bladder body 322, causing the nitrogen to be released rapidly. This can quickly cover the cable connection, isolate oxygen, achieve the fire extinguishing effect, prevent the fire from spreading, and reduce the damage range and safety risks of the cable.

[0041] In this embodiment, the sealing bladder 4 includes a ring 41, an annular sealing part 42, and an air guide tube 43. Both ends of the fixed tube 1 are equipped with rings 41, and an annular sealing part 42 is installed inside the ring 41. Multiple air guide tubes 43 are connected to the annular sealing part 42, and the multiple air guide tubes 43 are respectively connected to the insertion cavities in multiple hollow blocks 31. When the annular sealing part 42 is inflated, the gas is evenly distributed to the insertion cavity of each hollow block 31 through the air guide tubes 43, causing the elastic push part 33 to move outward. The top bladder part 32 on its outer side can support the V-shaped limiting part 2, so as to achieve uniform clamping of the cable and avoid uneven force or unstable fixation of the cable due to inconsistent local clamping force.

[0042] In this embodiment, the annular sealing part 42 includes an annular bladder 421, which is fixed inside the ring 41. The air guide tube 43 is connected to the outer periphery of the annular sealing part 42, and an air inlet valve 422 is connected to the outer side of the annular bladder 421. The air inlet valve 422 on the outer side of the annular bladder 421 serves as an inflation interface, facilitating connection with an external inflation device for rapid inflation. The inflation device is an air pump, and the outlet end of the air pump is connected to an inflation tube. An inflation head that cooperates with the air inlet valve 422 is connected to the inflation tube to inflate the annular bladder 421. Meanwhile, the structure of the air inlet valve 422 is similar to that of a car air inflator, with an air core installed in its middle. When deflating, simply press the air core in the middle. When the annular bladder 421 is inflated, its inner side fits tightly against the outer periphery of the cable, effectively preventing dust, moisture, and other external impurities from entering the fixed tube 1, avoiding environmental corrosion at the cable connection point, and also fixing the cable.

[0043] In this embodiment, multiple annular liners 423 are fixed inside the annular bladder 421 at intervals. The annular liners 423 are made of flexible material to adapt to the deformation of the annular bladder 421. When the annular bladder 421 is inflated, the annular liners 423 can limit the irregular deformation of the annular bladder 421, ensuring that the annular bladder 421 expands uniformly in the radial direction, making the annular bladder 421 fit more tightly with the cable and the fixing tube 1, and improving the sealing and clamping effect.

[0044] Example 2

[0045] In order to protect the device that can fix the cable, a cable sheath body 5 is installed on the outside of the device, as detailed below:

[0046] A cable sheath tube for fixing cables is provided, used in the aforementioned cable fixing device. It includes a cable sheath tube body 5, with the cable fixing device installed inside the cable sheath tube body 5 for securing the cable. The cable sheath tube body 5 serves as a load-bearing and protective structure, internally housing the cable fixing device to form an integrated cable protection and fixing structure. The cable sheath tube body 5 possesses certain mechanical strength and protective performance, providing initial anti-collision and anti-wear protection for the internal fixing device and cable. When the cable passes through the cable sheath tube body 5 and the internal fixing device, the fixing device secures the cable. The cable sheath tube body 5 then wraps around the cable and fixing device from the outside, further blocking external impacts and environmental erosion, forming double protection. This integrated design combines fixing and protection functions, simplifying the cable installation process and effectively extending the cable's service life.

[0047] In a specific embodiment, in order to facilitate the disassembly of the device that can fix the cable, a threaded channel is opened in the main body 5 of the cable sheath tube, and threads are provided on the outer periphery of the fixing tube 1, so that the fixing tube 1 can be spirally installed inside the fixing tube 1, thereby achieving detachable installation.

[0048] The specific working principle of this invention is as follows:

[0049] In the initial state of the device, the V-shaped limiting member 2 inside the fixed tube 1 is in a naturally open state, and the bladder component 3 and the sealing bladder 4 are in an uninflated and retracted state, which facilitates the insertion of the cable. Then, the two cables that need to be connected are passed through the two ends of the fixed tube 1 respectively. After the cable connection operation is completed on the outside of the fixed tube 1, the cable is moved so that the connection point is located in the clamping area surrounded by multiple V-shaped limiting members 2 inside the fixed tube 1.

[0050] By connecting the air inlet valve 422 of the sealing bladder 4 to the external inflation device, air is inflated into the annular bladder 421 of the annular sealing part 42. The gas in the annular bladder 421 flows into the insertion cavity of multiple hollow blocks 31 through multiple air guide tubes 43, so as to achieve uniform gas distribution. After the gas enters the insertion cavity of the hollow block 31, it pushes the piston plate 332 of the elastic push part 33 to slide outward against the elastic force of the spring 331. The piston plate 332 drives the bladder block 321 and the top bladder body 322 of the top bladder part 32 to extend out of the insertion cavity.

[0051] After the top bladder 322 extends, it applies a continuous supporting force to the hinge of the two limiting rods 21 of the V-shaped limiting member 2, forcing the two limiting rods 21 to rotate around their respective connection points with the U-shaped shell 11, and the opening of the V-shaped structure narrows, thereby achieving the supporting clamping of the cable.

[0052] At the same time, the annular bladder 421 expands synchronously during the inflation process, and its inner side is tightly attached to the outer periphery of the cable, completing the sealing of the end of the fixing tube 1, preventing external impurities from entering, and forming a secondary clamping, further improving the cable fixing stability.

[0053] The annular liner 423 inside the annular bladder 421 ensures that the annular bladder 421 expands evenly, avoiding local deformation that could affect the sealing and clamping effect. The nitrogen filled in the top bladder 322 not only ensures the stability of the top support force, but also releases nitrogen to extinguish the fire when the cable is accidentally burned, preventing the fire from spreading.

[0054] When it is necessary to disassemble or adjust the cable, the gas in the sealing bladder 4 is released through the air inlet valve 422. The rebound force of the spring 331 drives the piston plate 332 and the top bladder 32 to reset, and the V-shaped limit member 2 returns to the open state, so that the cable can be taken out or adjusted. The device can be reused.

[0055] The embodiments of the present invention have been described above, but the embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments described above, all of which are within the protection scope of the embodiments described above.
