Description

Technical Field

[0001] This invention relates to the field of electrical components technology, and in particular to an armored control cable resistant to high-pressure testing. Background Technology

[0002] Electrical components are the core parts that enable circuit switching and control functions. Cables are the carriers that connect electrical components and transmit electrical signals or energy. The compression armor layer is a protective structure wrapped around the outer layer of the cable and reinforced with metal or high-strength materials to resist external forces such as compression and impact, and protect the internal core wires and insulation layers of the cable.

[0003] Chinese patent application CN120261038B discloses a multi-harness mining pressure-resistant cable. It features a central sleeve containing a central wire harness, with an insulation layer between the central wire harness and the inner surface of the central sleeve. Multiple sector-shaped sleeves are installed outside the central sleeve, surrounding it. Each adjacent sector-shaped sleeve has a positioning wing plate and a receiving groove for accommodating the positioning wing plate. When the multiple sector-shaped sleeves are joined together, the positioning wing plates connect them end-to-end. Furthermore, the sector-shaped sleeves are positioned and limited by their sides and the positioning wing plates, ensuring the stability of their relative positions. This improves the stability of the central wire harness and side wire harness positions, thereby ensuring the stability and safety of the cable during use.

[0004] In the aforementioned patent, when a cable is subjected to compression, existing cable compression resistance mainly relies on multiple components spliced ​​together to form a protective structure, using rigid restraint to maintain the stability of the internal structure and thus resist external compression. This method can only achieve basic protection through the rigid support of the rigid structure. When faced with a violent impact, the rigid structure cannot absorb the impact energy and is prone to stress concentration leading to protection failure. Furthermore, when faced with continuous mechanical pressure, the rigid structure is not only prone to permanent deformation that cannot be restored, but may also directly damage the internal core components due to rigid compression, ultimately leading to a decrease in the cable's compressive strength.

[0005] Therefore, we propose an armored control cable resistant to high-pressure testing. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the defects of the prior art. The present invention proposes an armored control cable that is resistant to strong pressure testing. This solves the problem in the background art that the cable's anti-compression structure is formed by splicing multiple components to form a protective structure, which makes the rigid protection difficult to absorb impact and prone to failure, and the deformation is difficult to restore and damage the internal core components, ultimately leading to a decrease in the cable's compressive strength.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an armored control cable resistant to high-pressure testing, comprising a cable core, a metal layer fixedly installed on the outer surface of the cable core, a pressure-resistant component for protecting the cable core provided on the outer surface of the metal layer, and a sheath fixedly installed on the outer surface of the pressure-resistant component; the pressure-resistant component includes a pressure-resistant ring A and a pressure-resistant ring B disposed on the outer surface of the metal layer, the pressure-resistant ring B being inclinedly disposed on the outer surface of the metal layer, and one side of the pressure-resistant ring A and one side of the pressure-resistant ring B being in contact with each other; both the pressure-resistant ring A and the pressure-resistant ring B include a damping ring inside, a support ring is provided on the inner wall of the damping ring, a triggering component and a main air bladder for triggering the inflation of the triggering component are fixedly installed on the inner wall of the support ring, four sets of main air bladders and triggering components are provided, the triggering component is located between two sets of main air bladders, the triggering component is fixedly installed on the outer surface of the metal layer, a secondary air bladder is provided inside the main air bladder, and a non-Newtonian fluid is provided inside the damping ring.

[0008] Furthermore, the main airbag is equipped with an air outlet pipe and an air inlet pipe, both of which are connected to the auxiliary airbag. A one-way valve is fixedly installed inside the air outlet pipe and the air inlet pipe, and a thread is provided at one end of both the air outlet pipe and the air inlet pipe.

[0009] Furthermore, an mounting plate is fixedly installed on the outer surface of the auxiliary airbag. There are four sets of mounting plates, with two mounting plates in each set. One mounting plate has a threaded air inlet on its surface, and the other mounting plate has a threaded air outlet on its surface. The mounting plate is connected to the air outlet pipe, and the threaded air outlet is connected to the air inlet pipe.

[0010] Furthermore, the triggering component includes a fixed frame that is fixedly installed on the outer surface of the metal layer. A rectangular groove is opened on the surface of the fixed frame, and a cavity is opened on one side of the fixed frame. A movable block is movably arranged inside the rectangular groove, and a sliding plate is movably arranged inside the movable block. A squeezing plate is fixedly installed at one end of the sliding plate. The lower surface of the squeezing plate is in contact with the bottom of the cavity. The auxiliary airbag is located on the surface of the squeezing plate, and the movable block is fixedly installed with the support ring.

[0011] Furthermore, the movable block has a groove inside, and sliding grooves are formed on both sides of the inner wall of the groove. A spring is fixedly installed on the top of the sliding groove, and a slider is fixedly installed on one end of the spring. The slider is fixedly installed on the sliding plate, and the slider is located on both sides of the sliding plate.

[0012] Furthermore, the support ring surface has a threaded hole A, the movable block surface has a threaded hole B, a bolt is installed inside the threaded hole B, and the threaded hole A is fixedly installed to the movable block by the bolt.

[0013] Furthermore, a Velcro strap A is fixedly installed on the inner wall of the damping ring, and a Velcro strap B is fixedly installed on the outer surface of the support ring, with the Velcro strap B and the Velcro strap A fitting together.

[0014] Furthermore, the inner wall of the damping ring is provided with slots that are compatible with bolts.

[0015] Furthermore, the support ring is a component made of glass fiber reinforced nylon.

[0016] Furthermore, the triggering components inside the pressure-resistant ring B are located between the two sets of triggering components inside the pressure-resistant ring A, and there are also four sets of triggering components inside the pressure-resistant ring B. The triggering components inside the pressure-resistant ring A and the pressure-resistant ring B are arranged in the same row at the same angle on the surface of the metal layer.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The armored control cable with high-pressure resistance proposed in this invention, when the cable is subjected to a violent impact, the non-Newtonian fluid inside the damping ring hardens due to its own properties, keeping the damping ring in a circular shape to resist the impact and absorb the impact force, protecting the cable core. When the cable is subjected to continuous compressive force, the pressure-resistant component gradually becomes elliptical. Then, the two sets of trigger components on the front gradually decrease in pressure, and the two sets of trigger components away from the pressure move outward and squeeze the two parts of the auxiliary airbag to seal it. Subsequently, the squeezed main airbag is released through the air outlet pipe to the auxiliary airbag. The airbag is inflated, filling the secondary airbag on the front with gas to prevent the triggering component from squeezing the cable core. Then, the triggering component moves to the threshold and stops, causing the anti-pressure component to stop deforming the cable. The cable core is protected by the main airbag, the secondary airbag, and the triggering component. When the continuous pressure disappears, the support ring made of glass fiber reinforced nylon gradually returns to a circular shape, allowing the triggering component, the main airbag, and the secondary airbag to return to a circular shape. Moreover, the triggering components inside the anti-pressure ring A and the anti-pressure ring B respectively block the positive and oblique pressure to achieve all-round protection, ultimately improving the cable's pressure resistance.

[0021] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0022] Example 1: To solve the technical problem of how to improve the compressive strength of cables, such as... Figures 1-4As shown, the following preferred technical solution is provided: an armored control cable resistant to high-pressure testing, comprising a cable core 1, a metal layer 2 fixedly installed on the outer surface of the cable core 1, a pressure-resistant component 3 for protecting the cable core 1 provided on the outer surface of the metal layer 2, and a sheath 4 fixedly installed on the outer surface of the pressure-resistant component 3; the pressure-resistant component 3 includes a pressure-resistant ring A31 and a pressure-resistant ring B32 disposed on the outer surface of the metal layer 2, the pressure-resistant ring B32 being inclinedly disposed on the outer surface of the metal layer 2, and one side of the pressure-resistant ring A31 and one side of the pressure-resistant ring B32 being in contact; both the pressure-resistant ring A31 and the pressure-resistant ring B32 include a damping ring 33 inside, and a support ring 34 is provided on the inner wall of the damping ring 33 to support... A trigger assembly 36 and a main airbag 35 for inflating the trigger assembly 36 are fixedly installed on the inner wall of the ring 34. Four sets of main airbags 35 and trigger assemblies 36 are provided. The trigger assembly 36 is located between two sets of main airbags 35 and is fixedly installed on the outer surface of the metal layer 2. A secondary airbag 37 is provided inside the main airbag 35. A non-Newtonian fluid is provided inside the damping ring 33. When the cable is subjected to a violent impact, the non-Newtonian fluid inside the damping ring 33 will, due to its own properties, block the impact force. Because the non-Newtonian fluid hardens upon impact, the damping ring 33 will still... The ring shape resists impact, and the impact force is absorbed by the non-Newtonian fluid. When the cable encounters continuous mechanical pressure, the entire pressure-resistant component 3 gradually becomes elliptical. When it becomes elliptical, the two sets of trigger components 36 facing the pressure gradually decrease in pressure, while the two sets of trigger components 36 away from the pressure move outward, squeezing and sealing the auxiliary airbags 37 at both points. The squeezed main airbag 35 then inflates the auxiliary airbags 37, gradually filling the auxiliary airbags 37 inside the two sets of trigger components 36 facing the pressure to prevent the trigger components 36 from squeezing the cable core 1. As the pressure continues... When the movement of the trigger component 36 reaches the threshold, the trigger component 36 will stop moving. At this point, the stopped trigger component 36 will also stop moving along with the anti-pressure component 3, and the cable will stop deforming. The cable core 1 inside the cable will be protected by the main airbag 35, the auxiliary airbag 37, and the trigger component 36. When the continuous pressure disappears, the support ring 34 will gradually reset into a circular shape, allowing the trigger component 36, the main airbag 35, and the auxiliary airbag 37 to return to a circular shape. Thus, through the joint cooperation of the damping ring 33, the main airbag 35, the auxiliary airbag 37, and the trigger component 36, the cable's anti-pressure capability is improved.

[0023] Specifically, when the cable is subjected to a violent impact, the non-Newtonian fluid inside the damping ring 33 instantly hardens due to its own properties. At this time, the damping ring 33 maintains its circular shape to resist the impact and absorbs the impact force, preventing the cable core 1 from being damaged by the impact. When the cable is subjected to continuous compressive force, the entire pressure-resistant component 3 gradually becomes elliptical. Then, the two sets of trigger components 36 that are under pressure on the front gradually depress, while the two sets of trigger components 36 that are away from the pressure move outward, thereby squeezing and sealing the two parts of the auxiliary airbag 37. Subsequently, the compressed main airbag 35 inflates the auxiliary airbag 37, allowing the auxiliary airbags 37 inside the two sets of trigger components 36 that are under pressure on the front to gradually fill with gas. This prevents the triggering component 36 from directly squeezing the cable core 1. Then, as the pressure continues to act, the movement of the triggering component 36 stops after reaching the threshold. The stopped triggering component 36, together with the anti-pressure component 3, comes to a standstill. At this time, the cable no longer deforms, and the cable core 1 is protected by the main airbag 35, the auxiliary airbag 37, and the triggering component 36. When the continuous pressure disappears, the support ring 34 gradually resets itself into a circular shape, while simultaneously driving the triggering component 36, the main airbag 35, and the auxiliary airbag 37 to return to a circular shape. Thus, through the joint cooperation of the damping ring 33, the main airbag 35, the auxiliary airbag 37, and the triggering component 36, the cable's anti-pressure effect is ultimately improved.

[0024] Example 2: To address the technical problem of how to further improve the compressive strength of cables, such as... Figures 4-11 As shown, the following preferred technical solution is provided: The main airbag 35 is movably equipped with an air outlet pipe 351 and an air inlet pipe 352, both of which are connected to the auxiliary airbag 37. One-way valves are fixedly installed inside the air outlet pipe 351 and the air inlet pipe 352. One end of the air outlet pipe 351 and the air inlet pipe 352 is threaded. Air is inflated into the auxiliary airbag 37 through the air outlet pipe 351, which allows the auxiliary airbag 37 to gradually expand and protect the cable core 1 when the cable is subjected to continuous compression. When the support ring 34 is restored, the additional air pumped into the auxiliary airbag 37 can be returned to the main airbag 35 through the air inlet pipe 352, allowing the air to be recycled and enabling the pressure-resistant component 3 to protect the cable for a long time, thereby improving the overall protection quality of the pressure-resistant component 3.

[0025] The auxiliary airbag 37 has a mounting plate 371 fixedly installed on its outer surface. There are four sets of mounting plates 371, with two plates in each set. One mounting plate 371 has a threaded air inlet 372 on its surface, and the other mounting plate 371 has a threaded air outlet 373 on its surface. The mounting plate 371 is connected to the air outlet pipe 351, and the threaded air outlet 373 is connected to the air inlet pipe 352. When installing the auxiliary airbag 37, after the auxiliary airbag 37 is placed inside the trigger component 36, the threads of the air outlet pipe 351 and the air inlet pipe 352 are connected to the threaded air inlet 372 and the threaded air outlet 373, allowing the gas inside the air outlet pipe 351 to enter the auxiliary airbag 37. At this time, the auxiliary airbag 37 will be filled with gas. Due to the compression and disconnection by the trigger component 36, the gas-filled auxiliary airbag 37 will form two semi-circular arcs located directly below the compression force.

[0026] Trigger component 36 includes a fixed frame 361 fixedly mounted on the outer surface of metal layer 2. A rectangular groove 365 is formed on the surface of the fixed frame 361, and a cavity 362 is formed on one side of the fixed frame 361. A movable block 363 is movably disposed inside the rectangular groove 365, and a sliding plate 3636 is movably disposed inside the movable block 363. A compression plate 3637 is fixedly mounted at one end of the sliding plate 3636. The lower surface of the compression plate 3637 is in contact with the bottom of the cavity 362. The auxiliary airbag 37 is located on the surface of the compression plate 3637. The movable block 363 is fixedly mounted to the support ring 34. The movable block 363 can move by cooperating with the rectangular groove 365. The movable block 363 is fixedly installed with the support ring 34, and the fixed frame 361 is fixedly installed with the metal layer 2. When the support ring 34 is squeezed, two sets of movable blocks 363 will descend, while the other two sets of movable blocks 363 will rise. The rising movable blocks 363 will squeeze the auxiliary airbag 37 with the squeezing plate 3637, making the auxiliary airbag 37 into two semicircles. At this time, the semicircular auxiliary airbag 37 will gradually fill with gas. The surface of the filled auxiliary airbag 37 will then contact the descending movable block 363, preventing the descending movable block 363 from continuing to descend. Thus, the auxiliary airbag 37 will protect the cable core 1, thereby blocking external compression.

[0027] The movable block 363 has a groove 3632 inside, and sliding grooves 3633 are formed on both sides of the inner wall of the groove 3632. A spring 3634 is fixedly installed on the top of the sliding groove 3633, and a slider 3635 is fixedly installed on one end of the spring 3634. The slider 3635 is fixedly installed on the sliding plate 3636. The slider 3635 is located on both sides of the sliding plate 3636. The groove 3632 can be used to store the sliding plate 3636 when the movable block 363 descends. When the movable block 363 rises, the sliding plate 3636 and the compression plate 3637 can rise together with the movable block 363, thereby compressing the auxiliary airbag 37.

[0028] The support ring 34 has a threaded hole A341 on its surface, and the movable block 363 has a threaded hole B3631 on its surface. A bolt 364 is installed inside the threaded hole B3631. The threaded hole A341 is fixedly installed to the movable block 363 by the bolt 364. The bolt 364 allows the movable block 363 and the support ring 34 to move synchronously. When the support ring 34 is compressed, the trigger component 36 will act synchronously, thereby immediately activating the auxiliary airbag 37 and the main airbag 35, so as to protect the cable core 1 at the moment of compression.

[0029] The inner wall of the damping ring 33 is fixedly installed with Velcro A332, and the outer surface of the support ring 34 is fixedly installed with Velcro B342. Velcro B342 is attached to Velcro A332. Velcro A332 allows the damping ring 33 to be disassembled and reused when the cable needs to be cut due to problems. New damping rings 33 can also be replaced into cables that have been in long-term use at any time, thereby increasing the safety of the cable.

[0030] The inner wall of the damping ring 33 has a groove 331 that is adapted to the bolt 364. By matching the groove 331 with the bolt 364, the groove 331 can be aligned with the position of the bolt 364 when installing the damping ring 33. Then the two ends of the damping ring 33 can be joined together to form a complete ring to protect against external impacts.

[0031] The support ring 34 is a component made of glass fiber reinforced nylon. Due to the inherent properties of glass fiber reinforced nylon, when subjected to strong impact, the glass fiber reinforced nylon, in combination with non-Newtonian fluid, can prevent the cable from deforming. When the cable is continuously compressed, the glass fiber reinforced nylon support ring 34, through its high toughness and high bending strength, can gradually change from a circular ring to an ellipse. When the continuous compressive force disappears, the support ring 34 can also gradually recover as the force disappears, forming a supporting force from the inside of the cable outward to support the integrity of the cable.

[0032] The triggering component 36 inside the pressure-resistant ring B32 is located between the two sets of triggering components 36 inside the pressure-resistant ring A31, and there are also four sets of triggering components 36 inside the pressure-resistant ring B32. The triggering components 36 inside the pressure-resistant ring A31 and the pressure-resistant ring B32 are arranged at the same angle and in the same row on the surface of the metal layer 2. The cable can be protected in all directions through the triggering components 36 inside the pressure-resistant ring A31 and the pressure-resistant ring B32. When the pressure comes from directly above or from the side, the pressure-resistant ring A31 will block it, and when the pressure comes from the oblique direction, the triggering component 36 inside the pressure-resistant ring B32 will block it, thereby achieving all-round protection.

[0033] Specifically, when the cable is subjected to continuous compression, the support ring 34, made of glass fiber reinforced nylon, gradually changes from a circular ring to an ellipse due to its high toughness and high bending strength. Simultaneously, because the support ring 34 is fixed to the movable block 363 by bolts 364, the deformation of the support ring 34 causes the movable block 363 to move within the rectangular groove 365 of the fixed frame 361. The two sets of movable blocks 363 under frontal pressure gradually descend, while the other two sets rise outwards. Next, the sliders 3635 on both sides of the slide plate 3636 rise with the movable blocks 363 within the sliding groove 3633 of the plate groove 3632. Simultaneously, the spring 3634 at the top of the sliding groove 3633 assists in the sliding, causing the compression plate 3637 at one end of the slide plate 3636 to compress the auxiliary airbag 37 located on the surface of the compression plate 3637, causing the auxiliary airbag 37 to become two sets of semicircles. Subsequently, the compressed main airbag 35 inflates the auxiliary airbag 37 through its movably installed air outlet pipe 351. A one-way valve ensures that gas can only enter and not exit, causing the auxiliary airbag 37 to gradually expand and be positioned directly below the compressive force. It contacts the descending movable block 363 and prevents it from descending further, thus protecting the cable core 1. When the continuous pressure disappears, the support ring 34 gradually resets into a circular shape due to its own characteristics, driving the movable block 363 back to its original position. The slide plate 3636 is stored back in the slot 3632 of the movable block 363. At the same time, the extra gas in the auxiliary airbag 37 returns to the main airbag 35 through the air inlet pipe 352 to achieve gas circulation. During this period, the damping ring 33 is fixed to the support ring 34 by the Velcro A332 on the inner wall and the Velcro B342 of the support ring 34. The groove 331 of the damping ring 33 is adapted to the bolt 364 to ensure that it forms a complete circular ring. With the help of the internal non-Newtonian fluid, it resists the impact. At the same time, the trigger component 36 inside the pressure-resistant ring A31 and the inclined pressure-resistant ring B32 respectively blocks the positive and oblique pressure, ultimately further improving the cable's pressure resistance.
