Description

Technical Field

[0001] This invention relates to the field of cable explosion-proof joint technology, and in particular to a multi-protection cable explosion-proof joint that integrates intelligent control and fire extinguishing. Background Technology

[0002] In flammable and explosive environments such as power systems, petrochemical plants, and mines, cable joints are critical nodes in power transmission, and their safety and reliability are paramount. However, cable joints are susceptible to factors such as current overload, poor contact, and insulation aging, which can easily lead to localized high temperatures, electrical sparks, or even fires. In severe cases, this can result in explosions, threatening personnel safety and the stable operation of equipment. Traditional explosion-proof cable joints often employ a single protective structure, relying solely on physical isolation or simple fire extinguishing devices, which presents the following problems: 1. Insufficient protection: Ordinary explosion-proof connectors use ordinary explosion-proof box materials, which have low fire resistance and poor explosion protection capabilities. They are all single-structure fire protection designs.

[0003] 2. Insufficient real-time monitoring capabilities: The lack of real-time monitoring and intelligent linkage functions, or the monitoring device being added to the outside of the cable explosion-proof box, increases additional labor costs and makes it impossible to respond quickly in the early stages of a fire, leading to the spread of the fire. In the event that the fire extinguishing function and effect cannot be achieved, it may also cause the fire to spread again. Maintenance personnel cannot detect cable joint faults, fires and fault locations in a timely manner.

[0004] 3. Limited explosion-proof performance: Traditional structures are insufficient in terms of explosion pressure release and secondary fire protection. Under high temperatures, the shell is prone to melting or bursting, which increases the risk of accidents. 4. Low fire extinguishing efficiency: Most existing fire extinguishing devices are passively triggered, such as heat-sensitive glass bulbs. The coverage of the extinguishing agent is limited, making it difficult to accurately extinguish fires in localized high-temperature areas of cable joints. To address the above issues, there is an urgent need for a cable joint protection solution that integrates real-time monitoring, intelligent control, multiple fire suppression systems, and high-efficiency explosion protection to improve safety levels in complex environments. We propose a multi-protection explosion-proof cable joint that integrates intelligent control and fire suppression. Summary of the Invention

[0005] In order to overcome the technical problems existing in the prior art, the present invention provides an explosion-proof cable connector with integrated intelligent control and fire extinguishing multiple protections.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: including two sets of protective shells, with a first mounting block and a second mounting block symmetrically fixedly installed on the sides of the two sets of protective shells respectively, the first mounting block and the second mounting block being positioned and snapped together, and two sets of cables being mirror-arranged inside the two sets of protective shells, with the cable joints located at the center of the protective shells, and an active mechanism, a cooperating mechanism and an auxiliary mechanism being arranged on the inner side of the protective shells. The active mechanism includes a protective housing, inside which a power supply module and a control module are installed, and on the side of the protective housing are a first detection group and an active fire extinguishing device. The mating mechanism includes a fixed plate, a slot through which the fixed plate is formed on its side, a mating plate is set inside the slot, and a limit block, a mating block and a support block are set on the side of the mating plate. The auxiliary mechanism includes an auxiliary frame, a storage cavity on the side of the auxiliary frame, a second detection group fixedly installed on the side of the auxiliary frame, and a pressure release capsule and a heat-conducting rod installed inside the auxiliary frame.

[0007] Furthermore, the protective housing is disposed inside a set of protective housings, and a first fixing rod is provided on the side of the protective housing and the first fixing rod penetrates the protective housing to the inside of the protective housing and is threadedly installed therein. The control module is disposed above the power supply module.

[0008] Furthermore, the first detection group is fixedly installed on the side of the protective housing and electrically connected to the contact of the monitoring module. The active fire extinguishing device is symmetrically arranged on the side of the protective housing and is threaded through and installed on the side of the protective housing and electrically connected to the contact of the power supply module.

[0009] Furthermore, the fixing plates are symmetrically fixedly installed on the inner sides of the two sets of protective shells, with the fixing plates attached to the side of the cable, and the mating plates are installed on the slotted wall surface by rotating a round shaft.

[0010] Furthermore, the grooved wall has an installation groove, and the limiting block is rotatably installed on the wall of the installation groove via a round shaft. The limiting block is a rectangular block made of iron. The mating block is fixedly installed through the mating plate on the side. The mating block is a rectangular block made of magnet. The support block is fixedly connected between the side of the limiting block and the wall of the installation groove.

[0011] Furthermore, the auxiliary frame is symmetrically arranged inside the two sets of protective shells. The inner side of the auxiliary frame is attached to the side of the cable. The side of the auxiliary frame is provided with a second fixing rod, which passes through the auxiliary frame and is threaded into the inside of the protective shell.

[0012] Furthermore, the air outlet of the pressure release capsule corresponds to the position inside the storage chamber. The structure of the pressure release nozzle of the pressure release capsule adopts a closed nozzle. A partition is snapped into the inside of the storage chamber. The heat-conducting rod extends through the auxiliary frame to the nozzle position of the pressure release capsule. The heat-conducting rod is an "L"-shaped rod made of heat-conducting material.

[0013] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. This invention sets up an active mechanism and an auxiliary mechanism. Through the active mechanism, smoke sensor / temperature and humidity sensor / pressure sensor + active fire extinguishing device and the auxiliary mechanism, pressure sensor + fire extinguishing sand, dual detection and fire extinguishing linkage are achieved to quickly suppress the initial stage of fire and provide redundant protection against secondary fires. The explosion-proof shell is made of continuous basalt fiber, which is resistant to high temperature and does not burst. Combined with the pressure buffer design of the fixed plate and the matching plate, it effectively resists the impact of explosion.

[0014] 2. By setting up a matching mechanism, this invention can achieve precise fire extinguishing and zone isolation. The fixed plate and the matching plate isolate the cable joint area into an independent space, so that the thermal aerosol fire extinguishing device can concentrate on covering the fire source. When the pressure exceeds the limit, the matching plate is pushed and rotated to release the pressure and trigger auxiliary fire extinguishing. The fire extinguishing sand is diffused to the entire cavity through the slot, achieving full-area fire extinguishing coverage.

[0015] 3. By setting up a pressure release capsule and a heat-conducting rod, the present invention can achieve dual triggering to ensure reliability. The pressure release capsule of the auxiliary mechanism supports electronic triggering. Through the control module and the passively triggered heat-conducting rod, the closed nozzle can be broken by sensing temperature. Even if the control system fails, it can still automatically release fire extinguishing sand to ensure that the fire extinguishing function is not interrupted in extreme cases.

[0016] 4. The present invention is easy to maintain through modular design. The protective shell and the auxiliary frame are fixed by the first and second fixing rods by threads. With the help of the first and second mounting blocks, the cable can be auxiliaryly constrained and fixed. The assembly and disassembly are convenient and reduce labor costs. The fire extinguishing device, such as the active fire extinguishing device and the air pressure release capsule, is independently integrated into the module. When replacing it, there is no need to damage the overall structure, which reduces the operation and maintenance costs.

[0017] 5. By setting a limiting block and a mating block, the support block can provide elastic support for the limiting block so that it fits against the side wall of the mounting groove. The mating plate can be vertically fixed inside the groove by being attracted to the side of the limiting block through the mating block. The mating plate isolates the inner space of the protective shell, so that the mating plate can be easily manually reset later.

[0018] 6. By installing an LCD display device on the side of the explosion-proof device, this invention enables on-site monitoring of data from temperature and humidity sensors, pressure sensors, capsule pressure sensors, and module power consumption within the explosion-proof device. The data is then displayed on the screen, making it clearer and easier for cable maintenance personnel to inspect and check the internal operating status of the cable explosion-proof joint. The operating data can also be uploaded to a data monitoring center via the Internet of Things to achieve real-time monitoring of the cable joint's operating status. Attached Figure Description

[0021] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0022] Example: Figures 1 to 4 As shown, an integrated intelligent control and fire extinguishing multi-protection explosion-proof cable connector includes two sets of protective shells 1. The two sets of protective shells 1 are mirror-mounted and snap-fitted together to form an explosion-proof shell, providing better sealing and waterproof performance. The material of the protective shell 1 is continuous basalt fiber, which has excellent fire resistance and high temperature resistance: 269℃ ~ 1100℃, maintaining stability under extreme temperatures; high temperature strength retention rate: it can still retain 80% of the original strength at 600℃; under the action of a flame at 1100℃, it does not deform, crack, melt, or drip. The protective shell 1 is filled with an alkali-free, high flame-retardant, elastic explosion-proof material inner liner. In addition, a liquid crystal display device 13 is fixedly installed on the side of one of the protective shells 1, which consists of a liquid crystal display screen and a wireless data module, etc., which can display data from internal sensors in real time and transmit data wirelessly. A first mounting block 11 and a second mounting block 12 are symmetrically fixedly installed on the sides of the two sets of protective shells 1, respectively. The first mounting block 11 is a semi-circular ring block with protrusions on the side, and the second mounting block 12 is a semi-circular ring block with protrusions on the side. 2 is a semi-circular ring plate with concave dots on the side. The first mounting block 11 and the second mounting block 12 can be positioned and snapped together. Stainless steel clips 14 are respectively sleeved on the side of the combination of the first mounting block 11 and the second mounting block 12 to enhance the explosion resistance. Two sets of cables 2 are mirrored inside the two sets of protective shells 1. The joint of the cable 2 is located at the center of the protective shell 1. An active mechanism 3 for active detection and fire extinguishing is set on the inner side of the protective shell 1 corresponding to the joint of the cable 2. An auxiliary mechanism 5 for assisting detection and fire extinguishing is set on the inner side of the two sets of protective shells 1. A cooperating mechanism 4 for assisting fire extinguishing is set on the inner side of the two sets of protective shells 1 between the active mechanism 3 and the auxiliary mechanism 5. The active mechanism 3 can actively detect and extinguish fires on the cable 2, thus achieving basic fire safety functions. like Figures 4 to 6As shown, the active mechanism 3 includes a protective housing 31 located inside a set of protective housings 1, with the protective housing 31 corresponding to the connector of the cable 2. The protective housing 31 is also made of continuous basalt fiber and is a rectangular box with one side open. A first fixing rod 311 is provided on the side of the protective housing 31 and penetrates the protective housing 31 into the interior of the protective housing 1 for threaded installation. The first fixing rod 311 is a "T"-shaped cylindrical threaded rod. The protective housing 31 can be fixedly installed inside the protective housing 1 through the first fixing rod 311. A power supply module 32 is provided inside the protective housing 31. The power supply module 32 is composed of multiple modular power supplies, which are lithium batteries and can monitor the battery level in real time. A control module 33 is provided on the upper side of the power supply module 32 and is located inside the protective housing 31. The control module 33 is an integrated circuit board, including a wireless control device, a networking device, and a power supply device. A first detection group 34 is provided on the side of the protective housing 31 near the cable 2. The detection group 34 is fixedly installed on the side of the protective housing 31 and electrically connected to the contacts of the power supply module 32. The power supply module 32 is an integrated unit of a smoke sensor, a temperature and humidity sensor, a pressure sensor, and a water immersion sensor, used to assist in monitoring fire and water seepage. Fire can be directly detected at the cable 2 joint through smoke and temperature detection. On the side of the protective housing 31, corresponding to the position of the first detection group 34, an active fire extinguishing device 35 is symmetrically arranged and threadedly installed on the side of the protective housing 31 and electrically connected to the contacts of the power supply module 32. The active fire extinguishing device 35 is a thermal aerosol fire extinguishing device. Specifically, the power supply module 32 provides power to the control module 33, the first detection group 34, and the active fire extinguishing device 35. The control module 33 judges whether there is a fire based on the information detected by the first detection group 34 and controls the active fire extinguishing device 35 to perform active fire extinguishing operation. The power supply module 32, the control module 33, the first detection group 34, and the active fire extinguishing device 35 are centrally located on the side of the protective housing 31, reducing additional labor costs. The protective housing 31, power supply module 32, and control module 33 can form an intelligent control device for intelligent control of each component; the power supply module 32, control module 33, and first detection group 34 can form an active monitoring device for preliminary monitoring of fire effects; the power supply module 32, control module 33, and active fire extinguishing device 35 can form an active fire extinguishing device for preliminary active fire extinguishing operations. The set-in cooperating mechanism 4 can cooperate with the active mechanism 3 to carry out centralized fire extinguishing operation at the joint of cable 2, and can isolate and separate the fire extinguishing area; like Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, the mating mechanism 4 includes symmetrically fixed plates 41 installed inside the two sets of protective shells 1, with the fixed plates 41 corresponding to the two sides of the protective shell 31. The fixed plates 41 are attached to the side of the cable 2. The fixed plates 41 are semi-circular ring plates. The corresponding fixed plates 41 can form a circular ring plate on the side of the cable 2, which further constrains the cable 2 and isolates the space at the cable 2 joint. The fixed plates 41 are provided with slots 42 that penetrate through them at equal intervals on the side. The slots 42 are fan-shaped slots. Inside the slots 42 A mating plate 43 is provided and is installed on the wall of the slot 42 via a circular shaft. The mating plate 43 is a fan-shaped plate. Specifically, the inner space of the protective shell 1 at the cable 2 joint is isolated by the fixing plate 41 and the mating plate 43. When the active fire extinguishing device 35 performs fire extinguishing operation, the strontium nitrate-based fire extinguishing agent released when the thermal aerosol is activated by the thermal wire or electrical signal can quickly fill the space isolated by the fixing plate 41, and more effectively carry out fire extinguishing operation in the fire extinguishing area within the space. The wall of the slot 42 has an installation slot 44, which is rectangular. A limiting block 45 is installed inside the installation slot 44 and is rotatably mounted on the wall of the slot 44 via a circular shaft. The limiting block 45 is a rectangular block made of iron. A mating block 46 is fixedly installed through the mating plate 43 at the position corresponding to the limiting block 45. The mating block 46 is a rectangular block made of magnet. A support block 47 is fixedly connected between the side of the limiting block 45 and the wall of the installation slot 44. The support block 47 is a corrugated arc-shaped elastic block. Specifically, the support block 47 provides elastic support for the limiting block 45, allowing it to fit against one side of the wall of the installation slot 44. The mating plate 43 is attracted to the side of the limiting block 45 via the mating block 46 and can be vertically fixed inside the slot 42. The fixing plate 41 isolates the inner space of the protective shell 1. When the active fire extinguishing is effective, no electric sparks or open flames will be generated at the cable 2 connector, allowing it to pass through. The control module 33 feeds back the detection information from the first detection group 34 to the staff, who can then perform maintenance and replacement of the active fire extinguishing device 35. When there are still electric sparks and open flames at the cable 2 joint after active fire extinguishing, the internal pressure of the space isolated by the fixed plate 41 and the mating plate 43 continues to increase due to the high temperature. At this time, the active fire extinguishing device 35 continues to perform fire extinguishing operations. The pressure pushes the mating plate 43 to squeeze the limiting block 45 to rotate. When the pushing force of the mating plate 43 is greater than the elastic support force of the support block 47, the mating plate 43 pushes the limiting block 45 to rotate into the mounting groove 44. The mating plate 43 rotates directly into a horizontal position, making the groove 42 open. This allows for auxiliary detection and fire extinguishing operations through subsequent components. In addition, when a fire occurs at the cable 2 joint and generates a large explosion pressure, the mating plate 43 will quickly push the limiting block 45 to rotate and open horizontally. This also buffers the pressurized gas and enhances the explosion-proof effect. The auxiliary mechanism 5 can assist in detecting the cable 2 joint and assist in fire extinguishing operations, thus more effectively preventing the occurrence of fire. like Figure 4 , Figure 9 and Figure 10As shown, the auxiliary mechanism 5 includes two sets of auxiliary frames 51 symmetrically arranged inside the protective shell 1. The auxiliary frames 51 are positioned to cooperate with the protective shell 31 so that the fixing plate 41 can be placed between the protective shell 31 and the auxiliary frame 51. The inner side of the auxiliary frame 51 is attached to the side of the cable 2. The corresponding auxiliary frame 51 can also constrain the cable 2. The auxiliary frame 51 is an arc-shaped frame with a trapezoidal cross-section. A second fixing rod 511 is provided on the side of the auxiliary frame 51 and passes through the auxiliary frame 51 to the inside of the protective shell 1 and is threaded thereon. The second fixing rod 511 is a "T"-shaped cylindrical threaded rod. The auxiliary frame 51 can be fixedly installed inside the protective shell 1 through the second fixing rod 511. A storage chamber 52 is provided on the side of the fixed plate 41. The storage chamber 52 is a fan-shaped cavity and can store fire extinguishing sand particles. A second detection group 53 is fixedly installed on the side of the auxiliary frame 51 near the fixed plate 41. The second detection group 53 consists of a pressure sensor and a temperature and humidity sensor. A pressure release capsule 54 is inserted through the auxiliary frame 51, and the outlet of the pressure release capsule 54 corresponds to the position inside the storage chamber 52. The pressure release capsule 54 can be an existing capsule device that can quickly release high-pressure gas. The structure of the pressure release nozzle of the pressure release capsule 54 needs to be a closed nozzle, which can actively release gas or release gas by breaking the temperature sensing element through high temperature. A partition is inserted inside the storage chamber 52. 55, which can block fire extinguishing sand particles, has a heat-conducting rod 56 on the side of the auxiliary frame 51, which extends through the auxiliary frame 51 to the nozzle position of the air pressure release capsule 54. The heat-conducting rod 56 is an "L"-shaped rod made of heat-conducting material. Specifically, during normal use, the temperature and humidity sensor of the second detection group 53 can detect another area isolated by the fixed plate 41, monitoring for electric sparks and open flames at non-joint locations. Alternatively, if there are still electric sparks and open flames at the joint after the above-mentioned active fire extinguishing, the plate 43 is forced to push the limiting block 45 to rotate, and the slot 42 is opened horizontally by its own rotation. At this time, the pressure sensor of the second detection group 53 can detect the pressure change inside the protective shell 1. The sensor of the second detection group 53 detects the above information. After the signal is fed back to the control module 33, the control module 33 controls the pressure release capsule 54 to actively release high-pressure gas. The high-pressure gas quickly sprays out the fire extinguishing sand particles inside the storage chamber 52. At this time, the partition 55 is pushed out of the storage chamber 52, and the fire extinguishing sand particles quickly fill the inside of the protective shell 1 through the slot 42, ensuring the absolute fire extinguishing operation of the cable 2. When the second detection group 53 detects or the control module 33 fails, a fire occurs inside the protective shell 1 and the temperature rises. The heat can be conducted to the closed nozzle of the pressure release capsule 54 through the heat conduction rod 56. The temperature sensing element is heated and breaks, and the pressure release capsule 54 passively releases high-pressure gas, which can also ensure the release of fire extinguishing sand from the storage chamber 52 to assist in the fire extinguishing operation. The control module 33 and the second detection group 53 can form an auxiliary monitoring device for re-monitoring when active fire extinguishing fails; the control module 33, the pressure release capsule 54 and the heat-conducting rod 56 can form an auxiliary fire extinguishing device for auxiliary fire extinguishing operation after active fire extinguishing fails, and can perform electronic triggering and passive triggering modes to ensure the operation of fire extinguishing action.

[0023] Working principle: During installation and disassembly: After normal wiring of cable 2, place one set of protective shells 1 on the lower side of cable 2. At this time, cable 2 is constrained and adhered to the inner side of the second mounting block 12, fixing plate 41, and auxiliary frame 51. Place the other set of protective shells 1 on the upper side of cable 2. At this time, the first mounting block 11 and the second mounting block 12 are snapped together and aligned. After the two sets of protective shells 1 are snapped together and fixed, they are tightened with bolts. At this time, the first mounting block 11, fixing plate 41, and auxiliary frame 51 on the side of the other set of protective shells 1 cooperate to adhere to the side of cable 2, achieving [the desired fit]. The cable 2 is constrained and fixed; conversely, after loosening and removing the bolts, the two sets of protective shells 1 can be peeled off. After loosening and disassembling by the first fixing rod 311 and the second fixing rod 511, the protective shell 31 and the auxiliary frame 51 can be quickly disassembled and cleaned as a whole, and vice versa; this achieves an integrated structure, and at the same time, it works with the auxiliary mechanism 5 to assist in fire detection and extinguishing, taking into account the accident of fire in special circumstances to the greatest extent, effectively curbing the possibility of fire recurrence after the active fire detection and extinguishing mechanism 3 actively detects and extinguishes the fire; and effectively and immediately extinguishing the fire after it occurs. During active fire suppression: The smoke sensor, temperature and humidity sensor, and pressure sensor of the first detection group 34 directly detect the joint of cable 2. The detection signal is fed back to the control module 33, which controls the active fire suppression device 35 to actively spray high-temperature airflow to rapidly decompose the burning material and reduce the oxygen concentration. The fixed plate 41 and the auxiliary plate 43 isolate the internal space of the protective shell 1, allowing the strontium nitrate-based fire extinguishing agent released by the active fire suppression device to quickly fill the space area of ​​cable 2 and complete the fire suppression operation. When a fire occurs at the joint of cable 2, causing excessive air pressure, the auxiliary plate 43 can be pushed over to directly squeeze the limiting block 45 to rotate, and rotate itself to a horizontal position after being limited by the limiting block 45. The slot 42 is open. The auxiliary plate 43 has a buffering effect on the air pressure, ensuring the explosion-proof effect of the protective shell 1. At this time, after the slot 42 is open, the temperature and humidity sensor and pressure sensor of the second detection group 53 detect the fire, and the detection signal is fed back to the control module 33 to determine whether auxiliary fire suppression is needed. In passive fire suppression: If a fire still exists at the cable 2 joint under active fire suppression, the active fire suppression device 35 continues to extinguish the fire. At the same time, the second detection group 53 sensors detect the fire and feed the detection signal back to the control module 33. The control module 33 controls the pressure release capsule 54 to actively release high-pressure gas. The high-pressure gas scatters the fire extinguishing sand particles inside the storage chamber 52 and sprays them out. After passing through the slot 42, the gas quickly fills the inside of the protective shell 1, ensuring absolute fire suppression. In the event of failure of the pressure release capsule 54 or the control module 33, heat can be conducted to the closed nozzle of the pressure release capsule 54 through the heat conduction rod 56. The pressure release capsule 54 passively releases high-pressure gas, which can also ensure the fire extinguishing sand particles inside the storage chamber 52 are sprayed out for fire suppression. Simultaneously, the second detection group 53 can detect the other space isolated by the fixed plate 41 at normal times to prevent fires from occurring at the non-joint locations of the cable 2.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
