Description

Technical Field

[0001] This utility model relates to the technical field of fire prevention devices for electrical equipment, specifically a self-triggered fire extinguishing module device with expandable thermal induction wire. Background Technology

[0002] With the widespread use of electrical equipment, fires caused by the use of electrical equipment occur frequently. Therefore, some electrical equipment is equipped with passive automatic fire extinguishing devices. Passive automatic fire extinguishing devices are devices that automatically activate the fire extinguishing device by using temperature changes or flame detection. When the passive automatic fire extinguishing device in the electrical cabinet encounters an electric arc or abnormal high temperature, it can automatically sense and quickly release highly insulating nano-microcapsule particles to block the conditions for flame combustion in the space of the electrical equipment, thereby achieving effective control and active protection against fire arcs inside the equipment.

[0003] For example, a passive automatic fire extinguishing module for electrical equipment with multiple triggers, patent number CN116407792A, is described in the prior art. This module has multiple independent fire extinguishing chambers and thermally sensitive wires with different temperature sensing ranges in each chamber. The thermally sensitive wires can trigger the extinguishing agent multiple times for intelligent fire extinguishing, solving the problem that existing passive automatic fire extinguishing devices can only trigger fire extinguishing once and cannot deal with reignition.

[0004] However, in use, the heat-sensitive wire only works on a single fire extinguishing module. When an electrical fire occurs, it cannot trigger other nearby fire extinguishing modules, thus failing to quickly sense and extinguish the initial electrical fire.

[0005] Therefore, in order to address the above problems, the applicant needs to design a self-triggered fire extinguishing module device with expandable thermal induction wires to solve the problem. Utility Model Content

[0006] The purpose of this invention is to provide a self-triggered fire extinguishing module device with expandable thermal induction wires to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a self-triggered fire extinguishing module device with expandable thermal induction wire, comprising a fire extinguishing module body.

[0008] It also includes: an induction wire mechanism disposed on the main body of the fire extinguishing module, and the induction wire mechanism is used to trigger the main body of the fire extinguishing module to start. The induction wire mechanism includes a first induction wire and a second induction wire connected to the main body of the fire extinguishing module, and a plurality of expandable expansion components are disposed between the first induction wire and the second induction wire. The expansion component includes a corrugated tube, and a fixing block is disposed at both ends of the corrugated tube. A clamping block is disposed on the fixing block, and the clamping block cooperates with the fixing block to lock the first induction wire or the second induction wire. A connecting component is disposed on the inner side of the corrugated tube, and the connecting component is used to connect the first induction wire and the second induction wire.

[0009] Furthermore, the connecting component includes a spiral hollow sleeve, and a connecting line is provided inside the spiral hollow sleeve. Both ends of the connecting line are provided with connecting pieces, and the connecting pieces are fixedly connected to the fixing block.

[0010] Through the above structural design, the connecting wires, protected by the spiral hollow sleeve, safely realize the signal transmission between the first and second sensing wires. The connecting piece provides a firm connection point with the fixed block. When the extension component is stretched or compressed to adapt to different distances, the electrical continuity of the sensing wires is always reliably maintained, which is a guarantee for realizing the linkage transmission of thermal sensing signals between multiple fire extinguishing modules.

[0011] Furthermore, a sliding sleeve is provided on the inner side of the spiral hollow sleeve, and a sliding rod is slidably provided on the inner side of the sliding sleeve. A connecting rod is fixedly provided on the sliding rod and the sliding sleeve, and the connecting rod is fixedly connected to the bellows.

[0012] Through the above structural design, the sliding of the slide rod within the sliding sleeve allows the connecting components to smoothly extend or retract synchronously with the expansion and contraction of the bellows. The connecting rod then fixes the sliding sleeve and slide rod assembly onto the bellows, ensuring coordinated movement between the two. This effectively prevents the bellows from pulling, squeezing, or twisting the internal connecting wires during expansion and contraction, greatly enhancing the mechanical reliability and service life of the overall structure of the expansion component and ensuring stable signal transmission under repeated expansion and contraction operations.

[0013] Furthermore, the fixing block is provided with mounting holes, and the clamping block is provided with mounting screws, and the mounting screws cooperate with the mounting holes to lock the fixing block and the clamping block.

[0014] With the above structural design, the mounting screws pass through the clamping block and are screwed into the mounting holes of the fixing block, which can generate a strong locking force. This allows the clamping block to tightly and reliably press and fix the first or second sensing line onto the connecting piece, ensuring that the connection point between the sensing line and the connecting component has excellent mechanical strength and electrical contact performance. At the same time, the screw locking method also facilitates on-site installation, disassembly and maintenance, improving the convenience of using the module.

[0015] Furthermore, the fire extinguishing module body is provided with a self-triggering insulating fire extinguishing agent, and the self-triggering insulating fire extinguishing agent is covered with a moisture-proof coating, and the first sensing wire and the second sensing wire are disposed on the moisture-proof coating.

[0016] Through the above structural design, the moisture-proof coating can effectively isolate the fire extinguishing agent below from moisture and prevent it from becoming damp, clumping, degrading in performance, or failing. This ensures the effectiveness and rapid response of the fire extinguishing agent after long-term storage. At the same time, placing the sensing wire on top of the moisture-proof coating protects the sensing wire itself and ensures that the sensing wire can directly and sensitively sense heat changes from the electrical equipment space. The thermal response speed will not be reduced due to the coating, thus balancing protection and functionality.

[0017] Furthermore, the self-triggered insulating fire extinguishing agent is formed by pressing granular fire extinguishing agent.

[0018] Through the above structural design, the granular extinguishing agent has a larger specific surface area and excellent flowability. When the module is triggered and released, it can quickly diffuse and fill the space of electrical equipment, forming a highly insulating asphyxiating environment, effectively blocking the combustion chain. Pressing it into shape ensures the structural stability and compactness of the extinguishing agent when stored in the module, preventing the particles from settling, separating, or creating voids during transportation or vibration, which would lead to uneven performance. On the other hand, the overall structure formed by pressing can produce the expected rupture and spray pattern at the moment of triggering, which is conducive to the rapid and uniform release of the extinguishing agent to cover the fire source area, improving the rapid suppression effect on initial fires and reignition.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the thermal sensing wire of the expandable thermal sensing wire self-triggered fire extinguishing module device can be expanded, thereby quickly sensing and extinguishing initial electrical fires, as detailed below:

[0020] When using this expandable thermal sensing wire self-triggered fire extinguishing module device, loosen the mounting screws and insert the sensing wires on the adjacent fire extinguishing modules into the inside of the fixing block, then tighten the mounting screws to facilitate the connection of the first and second sensing wires. After the sensing wires on the main bodies of the adjacent fire extinguishing modules are connected, the thermal sensing signal is transmitted in linkage between multiple fire extinguishing modules. When an electrical fire occurs, it can trigger multiple nearby fire extinguishing modules to quickly sense and extinguish the initial electrical fire.

[0021] When this expandable thermal sensing wire self-triggered fire extinguishing module device is in use, if the sensing wires on adjacent fire extinguishing modules of different specifications need to be connected, an external force is used to pull the corrugated pipe. The change in length of the corrugated pipe will drive the spiral hollow sleeve to change its length. The change in length of the spiral hollow sleeve will synchronously drive the connecting wire to change its length. Thus, when the expansion component is stretched or compressed to adapt to different distances, the electrical continuity of the sensing wire is always reliably maintained. This is the guarantee for realizing the linkage transmission of thermal sensing signals between multiple fire extinguishing modules and has a wide range of applications. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-4As shown, the self-triggered fire extinguishing module device with expandable thermal sensing wire of this utility model includes a fire extinguishing module body 1 and a sensing wire mechanism 2 disposed on the fire extinguishing module body 1. The sensing wire mechanism 2 is used to trigger the fire extinguishing module body 1 to start. The sensing wire mechanism 2 includes a first sensing wire 20 and a second sensing wire 22 connected to the fire extinguishing module body 1. A plurality of retractable extension components 21 are disposed between the first sensing wire 20 and the second sensing wire 22. The extension component 21 includes a corrugated tube 211, and a fixing block 210 is disposed at both ends of the corrugated tube 211. A clamping block 212 is disposed on the fixing block 210, and the clamping block 212 and the fixing block 210 are connected. The corrugated pipe 211 is equipped with a connecting component 215 on its inner side to lock the first sensing line 20 or the second sensing line 22. The connecting component 215 is used to connect the first sensing line 20 and the second sensing line 22. The fixing block 210 is provided with a mounting hole 213, and the clamping block 212 is provided with a mounting screw 214. The mounting screw 214 cooperates with the mounting hole 213 to lock the fixing block 210 and the clamping block 212. The fire extinguishing module body 1 is provided with a self-triggered insulating fire extinguishing agent, and the self-triggered insulating fire extinguishing agent is covered with a moisture-proof coating. The first sensing line 20 and the second sensing line 22 are set on the moisture-proof coating. The self-triggered insulating fire extinguishing agent is formed by pressing granular fire extinguishing agent.

[0029] With the above structural design, during use, loosen the mounting screw 214 and insert the induction wire on the adjacent fire extinguishing module into the inside of the fixing block 210, and then tighten the mounting screw 214. This will facilitate the connection of the first induction wire 20 and the second induction wire 22. After the induction wires on the adjacent fire extinguishing module bodies 1 are connected, the thermal induction signal linkage transmission between multiple fire extinguishing modules will be realized. When an electrical fire occurs, it can trigger multiple nearby fire extinguishing modules to quickly sense and extinguish the initial electrical fire.

[0030] The connecting component 215 includes a spiral hollow sleeve 2150, and a connecting line 2151 is provided inside the spiral hollow sleeve 2150. Both ends of the connecting line 2151 are provided with connecting pieces 2152, and the connecting pieces 2152 are fixedly connected to the fixing block 210. A sliding sleeve 2153 is provided on the inner side of the spiral hollow sleeve 2150, and a sliding rod 2154 is slidably provided on the inner side of the sliding sleeve 2153. A connecting rod 2155 is fixedly provided on the sliding rod 2154 and the sliding sleeve 2153, and the connecting rod 2155 is fixedly connected to the bellows 211.

[0031] Through the above structural design, when the sensing wires on the main body 1 of adjacent fire extinguishing modules of different specifications need to be connected, the corrugated pipe 211 is pulled by external force. The change in length of the corrugated pipe 211 will drive the spiral hollow sleeve 2150 to change its length. The change in length of the spiral hollow sleeve 2150 will synchronously drive the connecting wire 2151 to change its length. Thus, when the extension component 21 is stretched or compressed to adapt to different distances, the electrical continuity of the sensing wire is always reliably maintained. This is the guarantee for realizing the linkage transmission of thermal sensing signals between multiple fire extinguishing modules and has a wide range of applications.

[0032] Working principle: When using this self-triggered fire extinguishing module device with expandable thermal sensing wire, when the sensing wires on the main body 1 of adjacent fire extinguishing modules of different specifications need to be connected, the corrugated pipe 211 is pulled by external force. The change in length of the corrugated pipe 211 will drive the spiral hollow sleeve 2150 to change its length. The change in length of the spiral hollow sleeve 2150 will simultaneously drive the connecting wire 2151 to change its length. After the length change is completed, the mounting screw 214 is loosened and the sensing wire on the adjacent fire extinguishing module is inserted into the inside of the fixing block 210. Then the mounting screw 214 is tightened, which will facilitate the connection of the first sensing wire 20 and the second sensing wire 22. After the sensing wires on the main body 1 of adjacent fire extinguishing modules are connected, the thermal sensing signal linkage transmission between multiple fire extinguishing modules will be realized. When an electrical fire occurs, multiple nearby fire extinguishing modules can be triggered to quickly sense and extinguish the initial electrical fire.

[0033] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
