Description

Technical Field

[0001] This invention belongs to the field of intelligent early warning cable technology, specifically an intelligent early warning cable with an integrated detection module. Background Technology

[0002] Traditional cables face hidden dangers such as localized overheating and insulation aging in complex environments, and manual inspections are difficult to detect in time. Intelligent early warning cables, through embedded sensor networks (such as distributed fiber optic temperature measurement systems) and multi-source data fusion technology, can realize real-time monitoring of cable body temperature, strain, partial discharge and environmental parameters, providing a reliable basis for safe power monitoring and management.

[0003] In modern power systems, smart cables also include terminal heads, which serve as critical nodes in power transmission lines, connecting cables to other lines. Because smart cable terminal heads are constantly exposed to high voltage and high current, problems such as loose connections and aging insulation can easily lead to localized overheating or even fires. Traditional fire protection measures for smart cable terminal heads and cables typically involve heat-shrink film or fireproof tape, passively delaying the spread of fire. However, these methods cannot actively monitor for abnormal temperature rises at the cable terminal heads, making it difficult to respond quickly and effectively in the initial stages of a fire. Overheating at the terminal head can cause the rubber material on the cable surface to ignite and melt, potentially affecting other equipment. Summary of the Invention

The end of the metal pipe away from the fire extinguishing canister is slidably connected to the inside of the powder spraying pipe.

[0011] In the above technical solution, preferably, the cooling component includes a rotating rod, which is fixedly connected to the right end of the output shaft of the dual-axis motor. A heat insulation tube is connected to the left side of the flow guide sleeve. The heat insulation tube is sleeved on the surface of the cable. The left side of the inner wall of the heat insulation tube is fixedly connected to the surface of the cable. A return pipe is connected to the surface of the heat insulation tube. A return shroud is connected to the right side of the flow guide sleeve. The return shroud is fixedly connected to the surface of the cable. The right end of the return pipe is connected to the left side of the return shroud.

[0012] The right end of the rotating rod extends through to the right side of the reflux shroud. Fan blades are fixedly connected to both sides of the rotating rod surface. Cooling plates are fixedly embedded at the front and rear ends of the right side of the reflux shroud.

[0013] In the above technical solution, preferably, a fixing sleeve is fixedly connected to the right side of the return shroud, the fixing sleeve is fitted onto the surface of the fan blade, both sides of the top of the fixing sleeve are connected to vent pipes, and a sleeve plate is fixedly connected inside the fixing sleeve.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] This invention utilizes a transmission structure consisting of a dual-axis motor, a reducer, a sliding sleeve, a sliding rod, and a concave plate to drive the powder spraying pipe, temperature sensor, and flame sensor to reciprocate within a certain angle. This allows for scanning of various connected terminal areas, avoiding blind spots. Upon detecting a sudden temperature rise or flame signal, the audible and visual alarms respond quickly, and the controller activates a miniature solenoid valve, rapidly injecting extinguishing powder from the fire extinguishing canister into the oscillating powder spraying pipe. The spray range covers multiple installation locations, ensuring that the extinguishing powder can act on the ignition point and its surrounding area, thus improving the comprehensiveness of hazard detection.

[0020] Furthermore, while early warning fire extinguishing devices can respond quickly after a fire breaks out, they cannot solve the problem of continuous heat generation in cable cores caused by long-term operation. However, by designing the cooling components, including the transfer rod, heat insulation pipe, and return pipe, and adopting a design that combines internal circulation air cooling with cooling plates, a closed cooling system is formed. The dual-axis motor drives the fan blades to circulate the air in the heat insulation pipe in a directional manner, which, together with the cooling plates, actively cools the cable, avoiding the risk of cable insulation performance degradation caused by the introduction of external moisture in traditional air cooling. By continuously removing heat from the cable core, the operating temperature of the cable core can be controlled within a safe threshold, reducing the fire hazard caused by overheating and extending the service life of the cable core.

[0021] Furthermore, although it can achieve fire early warning and circulating cooling, there is still a problem of insufficient heat conduction efficiency and difficulty in quickly removing heat from the cable core. However, through the structural design of graphene heat-conducting film, arc plate and limiting sleeve in the heat-conducting component, the graphene heat-conducting film and arc plate can conduct the heat of the cable core to the air for heat exchange, ensuring that the air can fully contact the cable surface, avoiding direct contact between the cable core and the inner wall of the heat insulation pipe, and ensuring smooth air circulation path.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figures 1 to 11 As shown, the present invention provides an intelligent early warning cable with an integrated detection module, including a cable 1, a cable core 2 fixedly connected inside the cable 1, a connection terminal 3 fixedly connected to the left side of the surface of the cable core 2, a monitoring optical fiber module 4 fixedly connected inside the cable 1, and further including:

[0036] The fire warning and extinguishing device 5 is installed on the top of the cable 1 and is used to provide early warning and extinguish fire when the temperature of the cable core 2 is abnormal.

[0037] The fire extinguishing device 5 includes a flow guide sleeve 51, which is fixedly connected to the surface of the cable 1. A dual-axis motor 52 is fixedly connected to the top of the inner cavity of the flow guide sleeve 51 through a connecting plate. The left end of the output shaft of the dual-axis motor 52 passes through the left side of the flow guide sleeve 51 through a connecting rod and is fixedly connected to a reducer 53. A rotating seat 54 is provided at the output end of the reducer 53. A powder spraying pipe 55 is hinged inside the rotating seat 54 through a shaft. A fire extinguishing device 56 is provided on the right side of the flow guide sleeve 51. A warning device 57 is fixedly connected to the front of the flow guide sleeve 51. A cooling component 58 is provided on the left side of the flow guide sleeve 51. A temperature sensor 59 is hinged to the rear side of the left end of the powder spraying pipe 55 through a shaft. A flame sensor 510 is hinged to the front side of the left end of the powder spraying pipe 55 through a shaft.

[0038] The detection ends of temperature sensor 59 and flame sensor 510 face the area of ​​connection terminal 3 for real-time monitoring of temperature and flame signals.

[0039] Specifically, the reducer 53 is a worm gear reducer, the temperature sensor 59 is an infrared temperature sensor, which can measure the surface temperature in real time without direct contact with the cable core 2 and the connection terminal 3. The flame sensor 510 is an electronic device used to detect the presence of a flame, mainly by sensing the specific light waves and heat radiation emitted by the flame to determine whether a fire has occurred. Both the temperature sensor 59 and the flame sensor 510 are existing mature technologies. The temperature sensor 59 and the flame sensor 510 adopt an adjustable angle design with a shaft hinge, which allows them to quickly adjust the detection angle according to the actual layout of the connection terminal 3 and the monitoring requirements. Precisely targeting key areas prone to heat and fire enhances the reliability and adaptability of the fire protection system; the monitoring fiber optic module 4 is a functional module based on fiber optic sensing technology for real-time monitoring of cable operating status. It is mainly based on the Raman scattering effect and the principle of optical time-domain reflection. When a laser pulse is transmitted in an optical fiber, Raman scattered light is generated. The intensity of the anti-Stokes light changes with temperature, while the Stokes light is independent of temperature. By analyzing the ratio of the anti-Stokes light to the Stokes light, the temperature of each point along the optical fiber can be accurately calculated, and precise positioning can be achieved by combining the light speed time difference, thereby realizing real-time monitoring of cable temperature in the entire time domain and along the entire path.

[0040] like Figure 1 and Figure 7 As shown, the rotating seat 54 includes a sliding sleeve 541, which is fixedly connected to the output end of the reducer 53. A concave plate 542 is hinged to the surface of the powder spraying pipe 55 via a shaft. A sliding rod 543 is fixedly connected to the bottom of the concave plate 542. The sliding sleeve 541 is slidably sleeved on the surface of the sliding rod 543.

[0041] Specifically, when the motor output shaft rotates, it drives the sliding sleeve 541 to rotate slowly through the reducer 53. The sliding sleeve 541 slides on the surface of the sliding rod 543. At the same time, the sliding sleeve 541 pushes the sliding rod 543 and the concave plate 542 to rotate. Combined with the concave plate 542 and the powder spraying structure, the powder spraying pipe 55 can swing back and forth within a certain angle, realizing the monitoring of multiple cable cores 2 and connection terminals 3 by the temperature sensor 59.

[0042] like Figure 5 As shown, the warning device 57 includes a controller 571, which is fixedly connected to the front of the flow guide sleeve 51. The temperature sensor 59 and the flame sensor 510 are both electrically connected to the controller 571. The controller 571 is electrically connected to the miniature solenoid valve 562. An audible and visual alarm 572 is fixedly connected to the left side of the top of the controller 571.

[0043] Specifically, the controller 571 consists of a temperature controller 571 and a relay. The temperature controller 571, as the core monitoring unit, can collect and analyze real-time data transmitted by the temperature sensor 59 and the flame sensor 510. Through the preset temperature threshold, it can determine the temperature of the cable core 2 and the connection terminal 3. When the temperature exceeds the threshold, it outputs an electrical signal to the relay. The relay, as the execution unit, receives the signal and starts the miniature solenoid valve 562 to perform fire extinguishing.

[0044] like Figure 1 As shown, the fire extinguishing device 56 includes a fire extinguishing canister 561, which is located on the right side of the flow guide sleeve 51. The exhaust end of the fire extinguishing canister 561 is connected to a miniature solenoid valve 562, and the output end of the miniature solenoid valve 562 is connected to a metal pipe 563. The end of the metal pipe 563 away from the fire extinguishing canister 561 is slidably connected to the inside of the powder spraying pipe 55.

[0045] Specifically, a nozzle is connected to the left side of the bottom of the powder spraying pipe 55. When the powder spraying pipe 55 swings, it slides on the surface of the metal pipe 563. When the micro solenoid valve 562 is opened, the powder inside the fire extinguishing canister 561 is continuously and stably injected into the powder spraying pipe 55. Through the swing of the powder spraying pipe 55, it evenly covers the positions of multiple cable cores 2 and connection terminals 3, achieving all-round fire extinguishing.

[0046] like Figures 1 to 3 As shown, the cooling component 58 includes a rotating rod 581, which is fixedly connected to the right end of the output shaft of the dual-axis motor 52. The left side of the flow guide sleeve 51 is connected to a heat insulation pipe 582, which is sleeved on the surface of the cable 1. The left side of the inner wall of the heat insulation pipe 582 is fixedly connected to the surface of the cable 1. The surface of the heat insulation pipe 582 is connected to a return pipe 583. The right side of the flow guide sleeve 51 is connected to a return shroud 584, which is fixedly connected to the surface of the cable 1. The right end of the return pipe 583 is connected to the left side of the return shroud 584.

[0047] The right end of the rotating rod 581 extends to the right side of the reflux shroud 584. Fan blades 585 are fixedly connected to both sides of the surface of the rotating rod 581. Cooling plates 586 are fixedly embedded at the front and rear ends of the right side of the reflux shroud 584.

[0048] Specifically, the return shroud 584 consists of a square sleeve and a round sleeve. The heat insulation pipe 582 and the return pipe 583 are both made of fluororubber. The cooling chip 586 is a semiconductor cooling chip 586. The left end of the cooling chip 586 is the cold end, and the right end of the cooling chip 586 is the hot end. The right end of the output shaft of the dual-axis motor 52 drives the rotating rod 581 to rotate. The rotating rod 581 drives the fan blade 585 to rotate, thereby forming a directional air circulation in the closed loop composed of the heat insulation pipe 582, the return pipe 583, the return shroud 584, and the guide sleeve 51, which isolates the influence of the external environment on the cable.

[0049] like Figures 5 to 8 As shown, a fixed sleeve 6 is fixedly connected to the right side of the return shroud 584. The fixed sleeve 6 is fitted onto the surface of the fan blade 585. Ventilation pipes 7 are connected to both sides of the top of the fixed sleeve 6. A sleeve plate 14 is fixedly connected inside the fixed sleeve 6.

[0050] Specifically, the fan blade 585 on the right side can cool the hot end of the cooling chip 586 through the fixing sleeve 6, effectively preventing the cooling chip 586 from degrading due to excessive temperature and ensuring its continuous and stable operation. The two vent pipes 7 can realize directional exhaust and directional suction of air, eliminating the need to evacuate air in the distribution box to cool the cooling chip 586 and preventing hot air from interfering with surrounding electrical equipment.

[0051] like Figure 1 and Figure 5 As shown, a mounting sleeve 8 is fixedly connected to the surface of the cable 1. The mounting sleeve 8 is fitted onto the surface of the fire extinguisher 561 and the metal pipe 563. A clamping bolt 9 is threadedly connected to the front of the mounting sleeve 8. The rear end of the clamping bolt 9 contacts the surface of the fire extinguisher 561. A baffle 10 is fixedly connected to each of the four corners on the left side of the mounting sleeve 8. The left end of the baffle 10 is fixedly connected to the surface of the fixing sleeve 6.

[0052] Specifically, by setting the mounting sleeve 8 and the clamping bolt 9, the fire extinguisher 561 can be clamped and fixed. The clamping force of the fire extinguisher 561 can be flexibly adjusted to prevent the fire extinguisher 561 from falling off due to loosening. At the same time, it is convenient to replace the fire extinguisher 561 after use.

[0053] like Figure 3 and Figure 6 As shown, a heat-conducting fin 11 is fixedly connected to the left side of the cooling chip 586. The left side of the heat-conducting fin 11 is fixedly connected to the left side of the inner wall of the return shroud 584. A sealing ring 12 is fixedly connected to the left side of the inner wall of the guide sleeve 51 and the right side of the inner wall of the return shroud 584. The inner wall of the sealing ring 12 is in contact with the surface of the rotating rod 581.

[0054] Specifically, the heat-conducting fins 11 can increase the heat exchange area and quickly conduct the heat generated by the cooling chip 586 to the air circulating inside the return shroud 584, thereby improving the cooling effect of the cooling chip 586 on the air. The sealing ring 12 can seal the gaps in the guide sleeve 51 to prevent external moisture from entering the interior of the guide sleeve 51.

[0055] like Figures 1 to 4As shown, a heat-conducting component 13 is provided on the surface of the cable core 2. The heat-conducting component 13 includes a graphene heat-conducting film 131, which is fixedly connected to the surface of the cable core 2. Arc-shaped plates 132 are fixedly connected to the top and bottom of the inner wall of the heat insulation tube 582. A limiting sleeve 133 is fixedly connected to the surface of the heat insulation tube 582, and the limiting sleeve 133 is sleeved on the surface of the return tube 583.

[0056] Specifically, the graphene thermal conductive film 131 and the arc plate 132 can conduct the heat of the cable core 2 to the air for heat exchange, ensuring that the air can fully contact the cable surface, avoiding direct contact between the cable core 2 and the inner wall of the heat insulation pipe 582, and ensuring smooth air circulation path.

[0057] like Figure 1 As shown, a sleeve plate 14 is fixedly connected to the surface of the powder spraying pipe 55 via a bearing. A positioning plate 15 is fixedly connected to the front and rear ends of the right side of the sleeve plate 14. The right end of the positioning plate 15 is fixedly connected to the left side of the guide sleeve 51.

[0058] Specifically, the sleeve plate 14 and the positioning plate 15 can support the powder spraying pipe 55, ensuring the stability of the powder spraying pipe 55 during the swinging process and preventing the powder spraying pipe 55 from shifting left and right when rotating.

[0059] Working principle and usage process of this invention:

[0060] The user first installs the connection terminal 3 in the designated location. When current flows through the cable core 2, the cable core 2 and the connection terminal 3 will generate a certain temperature. Then, the dual-axis motor 52 can be started. The left end of the output shaft of the dual-axis motor 52 drives the sliding sleeve 541 to rotate through the reducer 53. The sliding sleeve 541 drives the concave plate 542 to rotate through the sliding rod 543. The concave plate 542 will drive the powder spraying pipe 55 to swing back and forth within a certain angle, thereby driving the temperature sensor 59 and the flame sensor 510 to swing and monitor. It can detect the cable core 2 and the connection terminal 3 at different locations. When an abnormal temperature rise or fire is detected, the audible and visual alarm 572 will issue a warning. The controller 571 will activate the micro solenoid valve 562 to inject the extinguishing powder in the fire extinguishing canister 561 into the interior of the powder spraying pipe 55. Since the powder spraying pipe 55 is in a reciprocating swinging state, it can achieve accurate fire extinguishing at multiple installation locations.

[0061] The right end of the output shaft of the dual-axis motor 52 drives the rotating rod 581 to rotate, and the rotating rod 581 drives the fan blade 585 to rotate. The fan blade 585 pushes the air, causing the air to circulate in a closed loop composed of the heat insulation pipe 582, the return pipe 583, the guide sleeve 51, and the return shroud 584. The left end of the cooling chip 586 cools the air. The cooled air re-enters the guide sleeve 51 and flows back to the surface of the cable core 2 through the heat insulation pipe 582, circulating and carrying away the heat of the cable core 2, maintaining the temperature of the cable core 2 within a safe operating range.
