Description

Technical Field

[0001] The utility model relates to the field of fire extinguishing patches, and particularly relates to a fire extinguishing patch. Background Art

[0002] At present, in distribution devices such as distribution boxes, distribution cabinets, and control cabinets, a large number of electrical components, cables, and cable joints are installed inside. The main reasons for the fire in the distribution device include short - circuit fire, leakage fire, overload fire, and fire caused by excessive contact resistance. When a fire occurs, the cabinet door is closed inside the cabinet, and it is not easy for people to find it. When the fire spreads to the outside, people can find it. At this time, when extinguishing the fire, the equipment inside the cabinet has been damaged by the flame. Not only is the fire - fighting not timely, but also the loss will increase. To solve the above - mentioned problems, we propose a fire extinguishing patch. Content of the Utility Model

[0003] The purpose of the utility model is to provide a fire extinguishing patch, and its advantage is that it can extinguish the flame when the flame occurs.

[0004] The above - mentioned technical purpose of the utility model is achieved through the following technical solutions: a fire extinguishing patch, including an outer melting layer, the inside of the outer melting layer is filled with flame - extinguishing capsules, the inside of the flame - extinguishing capsules is filled with perfluoropentanone fire extinguishing agent, the top of the flame - extinguishing capsules is provided with a connecting melting layer, the top of the connecting melting layer is provided with a flame - retardant layer, the inside of the flame - retardant layer is respectively provided with an iron sheet one and a magnet, the top of the flame - retardant layer is provided with an adhesive layer, and the inside of the connecting melting layer is fixedly sleeved with an iron sheet two.

[0005] By adopting the above - mentioned technical solutions, through the setting of the flame - extinguishing capsules, the perfluoropentanone fire extinguishing agent inside the flame - extinguishing capsules reacts with the flame when the flame occurs, and can suffocate and extinguish the flame; through the setting of the magnet, the iron sheet one, and the iron sheet two, the outer melting layer and the flame - extinguishing capsules are fixed by magnetism, and can be adapted to various iron - type distribution cabinet bodies; through the setting of the flame - retardant layer, the flame can be retarded, and the spread space of the flame can be reduced.

[0006] The utility model is further set as: the bottom of the connecting melting layer and the top of the outer melting layer are integrally processed, and the top of the connecting melting layer is in contact with the bottom of the flame - retardant layer.

[0007] By adopting the above - mentioned technical solutions, through the setting of the connecting melting layer, the top of the connecting melting layer is in contact with the flame - retardant layer. Through the magnetic force of the magnet acting on the iron sheet one, the iron sheet one generates magnetic force and then acts on the iron sheet two inside it and adsorbs the iron sheet two, so as to realize the limit of the outer melting layer, and the magnetic force of the magnet will not be affected in the flame.

[0008] The utility model is further set as: the flame - retardant layer is specifically a fire - proof cloth, and the iron sheet one is arranged inside the flame - retardant layer.

[0009] With the above technical solution, through the setting of the flame retardant layer, when the flame extinguishing capsule melts, the flame retardant layer can block the flame, avoiding damage to the adhesive layer by the flame, thus affecting the adhesion effect of the adhesive layer. And after the perfluoroketone fire extinguishing agent inside the flame extinguishing capsule is released, it can quickly extinguish the flame, ensuring to the greatest extent that the adhesion effect of the adhesive layer will not be weakened.

[0010] The present utility model is further configured as: notch openings are provided inside both the flame retardant layer and the adhesive layer, and the first iron sheet and the magnet are both located inside the notch openings.

[0011] With the above technical solution, the setting of the notch opening facilitates the removal and installation of the magnet, and the adhesion effect of the adhesive layer will not be affected after the magnet is installed.

[0012] The present utility model is further configured as: the melting point temperature of the outer melting layer is 60 °C, and the melting point temperature of the flame extinguishing capsule is 70 °C.

[0013] With the above technical solution, the normal temperature inside the power distribution device is 40 - 50 °C, while the flame combustion temperature is at least greater than 200 °C. When the flame burns, the temperature of the flame increases the internal temperature of the device. When the internal temperature of the device rises to 60 °C, the outer melting layer begins to melt. As the temperature increases to 70 °C, the flame extinguishing capsule melts, and the perfluoroketone fire extinguishing agent inside it will be released to extinguish the flame.

[0014] The present utility model is further configured as: the melting point temperature of the connecting melting layer is 300 °C.

[0015] With the above technical solution, the melting point temperature of the connecting melting layer is higher than that of the flame extinguishing capsule and the outer melting layer. Its function is to limit the second iron sheet, facilitating the adsorption and fixation of the outer melting layer and the flame extinguishing capsule through the second iron sheet and the first iron sheet.

[0016] In summary, the present utility model has the following beneficial effects:

[0017] By providing an outer melting layer inside the outer melting layer in the present utility model, when a flame occurs, the outer melting layer and the flame extinguishing capsule melt, and the perfluoroketone fire extinguishing agent inside the flame extinguishing capsule is released. The perfluoroketone will decompose to generate free radicals, and the free radicals react with the free radicals in the flame, thereby inhibiting the combustion chain reaction and extinguishing the flame. And the perfluoroketone can also reduce the oxygen concentration on the surface of the combustible, thus inhibiting the flame combustion;

[0018] By using a magnet, iron sheet 1 and iron sheet 2 to adsorb and limit the external melting layer and the flame extinguishing capsule, and bonding and fixing through the adhesive layer, the flame extinguishing sticker can meet the magnetic adsorption installation of various iron cabinets and the adhesive connection of other materials; and by adopting the magnetic adsorption external melting layer method, after the external melting layer, the flame extinguishing capsule and the connecting melting layer 3 melt, only the new external melting layer, the flame extinguishing capsule and the connecting melting layer 3 need to be replaced. The flame retardant layer can retard the flame and reduce the damage to the adhesive layer, and the structures of the magnet, iron sheet 1 and iron sheet 2 can be reused.

[0023] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Embodiment 1:

[0025] Refer to Figure 1 , Figure 2 and Figure 3, a fire extinguishing patch, comprising an outer melting layer 1. The inside of the outer melting layer 1 is filled with flame extinguishing capsules 2. The inside of the flame extinguishing capsules 2 is filled with perfluoropentanone fire extinguishing agent. The top of the flame extinguishing capsules 2 is provided with a connecting melting layer 3. The top of the connecting melting layer 3 is provided with a flame retardant layer 4. Inside the flame retardant layer 4, there are respectively an iron sheet 5 and a magnet 6. The top of the flame retardant layer 4 is provided with an adhesive layer 7. Inside the connecting melting layer 3, there is a fixedly sleeved iron sheet 8; by arranging the outer melting layer 1 inside the outer melting layer 1, when a fire occurs, the outer melting layer 1 and the flame extinguishing capsules 2 melt, and the perfluoropentanone fire extinguishing agent inside the flame extinguishing capsules 2 is released. Perfluoropentanone will decompose to generate free radicals, and the free radicals will react with the free radicals in the flame, thereby inhibiting the combustion chain reaction and extinguishing the flame. Moreover, perfluoropentanone can also reduce the oxygen concentration on the surface of the combustible, thereby inhibiting the flame combustion; by using the magnet 6, the iron sheet 5 and the iron sheet 8 to adsorb and limit the outer melting layer 1 and the flame extinguishing capsules 2 and fixing them through the adhesive layer 7, the fire extinguishing patch can meet the magnetic adsorption installation of various iron cabinets and the adhesive connection of other materials; and by adopting the method of magnetically adsorbing the outer melting layer 1, after the outer melting layer 1, the flame extinguishing capsules 2 and the connecting melting layer 3 melt, only the new outer melting layer 1, the flame extinguishing capsules 2 and the connecting melting layer 3 need to be replaced. The flame retardant layer 4 can retard the flame and reduce the damage of the flame to the adhesive layer 7, and the structures of the magnet 6, the iron sheet 5 and the iron sheet 8 can be reused.

[0026] Further, the bottom of the connecting melting layer 3 and the top of the outer melting layer 1 are integrally processed. The top of the connecting melting layer 3 is in contact with the bottom of the flame retardant layer 4. Through the setting of the connecting melting layer 3, the top of the connecting melting layer 3 is in contact with the flame retardant layer 4. Through the magnetic force of the magnet 6 acting on the iron sheet 5, after the iron sheet 5 generates magnetic force, it acts on the iron sheet 8 inside it and adsorbs the iron sheet 8, thereby realizing the limitation of the outer melting layer 1, and the magnetic force of the magnet 6 will not be affected in the flame.

[0027] Further, the flame retardant layer 4 is specifically a fireproof cloth. The iron sheet 5 is arranged inside the flame retardant layer 4. Through the setting of the flame retardant layer 4, when the flame extinguishing capsules 2 melt, the flame retardant layer 4 can block the flame and avoid the flame from damaging the adhesive layer 7, thereby affecting the adhesion effect of the adhesive layer 7. Moreover, after the perfluoropentanone fire extinguishing agent inside the flame extinguishing capsules 2 is released, the flame can be quickly extinguished, and to the greatest extent, the adhesion effect of the adhesive layer 7 is ensured not to be weakened.

[0028] Further, both the flame retardant layer 4 and the adhesive layer 7 are provided with notches 9 inside. The iron sheet 5 and the magnet 6 are both located inside the notches 9. The setting of the notches 9 facilitates the removal and installation of the magnet 6, and the adhesion effect of the adhesive layer 7 will not be affected after the magnet 6 is installed.

[0029] Furthermore, the melting point temperature of the outer melting layer 1 is 60°C, the melting point temperature of the flame extinguishing capsule 2 is 70°C, the normal temperature inside the distribution device is 40-50°C, and the flame burning temperature is at least greater than 200°C. When the flame burns, the temperature of the flame increases the temperature inside the device. When the temperature inside the device rises to 60°C, the outer melting layer 1 begins to melt. As the temperature increases to 70°C, the flame extinguishing capsule 2 melts, and the perfluorohexanone fire extinguishing agent inside it will be released to extinguish the flame.

[0030] Furthermore, the melting point temperature of the connecting melting layer 3 is 300°C, and the melting point temperature of the connecting melting layer 3 is higher than that of the flame extinguishing capsule 2 and the outer melting layer 1. Its function is to limit the iron sheet 2 8, so that the outer melting layer 1 and the flame extinguishing capsule 2 can be adsorbed and fixed through the iron sheet 2 8 and the iron sheet 1 5.

[0031] Brief description of the use process: When in use, the adhesive layer 7 can be pasted on different materials, and the outer melting layer 1 and the flame extinguishing capsule 2 can be adsorbed and fixed by the magnet 6 adsorbing the iron sheet 1 5 and the iron sheet 1 5 adsorbing the iron sheet 2 8.

[0032] When facing iron materials, the magnet 6 can be directly adsorbed onto the iron, and with the adhesive layer 7, double fixation can be achieved; when the adhesive layer 7 is torn off once and the adhesion effect decreases, the magnetic force of the magnet 6 will not change. It should be noted that the adsorption strength of the magnet 6 on the iron sheet 1 5 and the iron sheet 2 8 must be at least greater than the weight of the outer melting layer 1, the flame extinguishing capsule 2, the connecting melting layer 3 and the iron sheet 2 8. At the same time, the adsorption strength of the magnet 6 and iron materials, such as the distribution cabinet, when adsorbed, must be at least greater than the total structural weight of the flame extinguishing sticker except the magnet 6.

[0033] After the flame extinguishing iron is connected, when a flame occurs, the flame temperature is greater than 60°C, 70°C, and 300°C, which will melt the outer melting layer 1, the flame extinguishing capsule 2, and the connecting melting layer 3 in sequence;

[0034] The outer melting layer 1 melts to expose the flame extinguishing capsule 2 inside it. When the flame extinguishing capsule 2 melts, the perfluorohexanone inside it is released and decomposed to generate free radicals. The free radicals react with the free radicals in the flame and reduce the oxygen concentration around the flame, thereby suffocating the flame.

[0035] Under normal conditions, the flame extinguishing capsule 2 can extinguish the flame within a few seconds after being released, and the temperature inside the device will not reach 300°C. Therefore, the flame extinguishing capsule 2 will not melt during the time after the flame occurs and is extinguished. Even if the flame retardant layer 4 melts, it will not produce excessive flame impact.

[0036] This specific embodiment is only an interpretation of the present utility model, and it does not limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment that do not contribute creatively as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
