Description

Technical Field

[0001] The present invention relates to the technical field of safety fire fighting, and in particular to a ready-to-install intelligent fire extinguishing device. Background Art

[0002] Fire extinguishers are one of the common firefighting equipment, which usually contain chemicals to put out fires. With the emergence of aerosols, aerosol fire extinguishers have become a new breakthrough in the application of fire extinguishers. Compared with traditional chemical fire extinguishers, aerosol fire extinguishers combine high-efficiency gas-generating aerosol agents with fire-extinguishing particle generators, using the heat and power of aerosol agents to generate fire-extinguishing gas, so that the fire-extinguishing particle generator decomposes and releases high-efficiency fire-extinguishing particles. It is superior in portability, safety and fire-extinguishing ability, so it is widely used in electrical, automotive and other fields.

[0003] However, most of the existing aerosol fire extinguishers are manually triggered. Once a fire occurs inside an electrical component with a small space (such as a power cabinet, etc.), the fire extinguisher cannot be manually opened in time to put out the fire, which easily makes the fire difficult to control.

[0004] Therefore, there is an urgent need for a new fire extinguishing device that can be used to extinguish fire in time when a fire occurs inside an electrical component in a narrow space. Summary of the invention

[0005] The technical problem to be solved by the embodiments of the present invention is to provide a ready-to-install intelligent fire extinguishing device, which can be used to promptly extinguish a fire when a fire occurs inside an electrical component in a narrow space.

[0006] In order to solve the above technical problems, the embodiment of the present invention provides a ready-to-use intelligent fire extinguishing device, including a fire extinguishing composition, a thermal ignition rod and a temperature sensing detection line; wherein,

[0007] The fire extinguishing composition is filled in the closed shell, and when burned, it automatically decomposes to generate aerosol fire extinguishing substances, which are discharged to the outside of the closed shell through a plurality of first through holes preset on the closed shell;

[0008] One end of the heat ignition rod is located outside the closed shell and connected to the temperature sensing detection line, and the other end extends into the closed shell through a second through hole preset on the closed shell and connected to the fire extinguishing composition, and the heat ignition rod is driven to burn by the temperature sensing detection line to ignite the fire extinguishing composition;

[0009] Among them, after the closed shell is fixed in the designated electrical component and at least one of the first through holes thereon is set toward a specific ignition point in the designated electrical component, if the ignition point catches fire, the temperature will be detected by the temperature sensing detection line and transmitted to the thermal ignition rod, so as to trigger the thermal ignition rod to automatically burn, thereby driving the fire extinguishing composition to burn and decompose to produce aerosol fire extinguishing substances, which are further released through each of the first through holes to extinguish the ignition point; the automatic combustion of the thermal ignition rod is triggered when the auto-ignition temperature of the ignition point exceeds the temperature detected and transmitted by the temperature sensing detection line after the ignition point catches fire.

[0010] Among them, it also includes: a wrapping cushion layer; among them,

[0011] The wrapping cushion layer is arranged in the closed shell and wrapped around the outside of the fire extinguishing composition, and is provided with a plurality of holes for releasing aerosol fire extinguishing substances generated by combustion and decomposition of the fire extinguishing composition.

[0012] Wherein, the wrapping cushion layer is a component of a high melting point porous insulating material.

[0013] Wherein, the auto-ignition temperature of the thermal ignition rod is lower than the ignition temperature of the fire extinguishing composition.

[0014] The fire extinguishing composition is composed of metal salt particles, organic compounds and a binder for bonding the metal salt particles and the organic compounds together;

[0015] The metal salt particles are a mixture of one or more components of potassium bicarbonate, potassium dihydrogen phosphate, sodium bicarbonate, potassium nitrate, strontium nitrate, and dicyandiamide;

[0016] The organic compound is a mixture of one or more components of dimethyl diamide, melamine, phenolic resin, hexamethylenetetramine, ammonium chloride, and melamine polyphosphate.

[0017] It also includes: a remotely controlled igniter; wherein the igniter is connected to the middle part of the thermal ignition rod, and when receiving an external command, it instantly generates an ignition temperature exceeding the auto-ignition temperature of the thermal ignition rod to drive the thermal ignition rod to burn.

[0018] The igniter is composed of a receiving circuit, a decoding circuit, a relay circuit, an ignition circuit and a power supply module.

[0019] The enclosed housing is a nylon glass fiber insulation flame retardant material component, which is formed by sealingly connecting an upper cover body and a mounting base plate;

[0020] The upper cover body is in a semi-enclosed structure, with a plurality of the first through holes on its bottom wall, a second through hole on one side wall, and a cavity with an opening toward the installation base plate and used to accommodate the wrapping cushion layer formed between the bottom wall and all the side walls;

[0021] The upper surface of the mounting base plate is sealed to cover the opening of the upper cover body through a sealing member and a locking mechanism, and the lower surface is provided with a fastener fixed to the designated electrical component.

[0022] Wherein, the locking mechanism comprises two buckle plates and two buckle rods respectively cooperating with the two buckle plates; Wherein,

[0023] The two gusset plates are respectively fixed on two opposite outer side walls of the upper cover body;

[0024] The two buckle rods are both fixed on the upper surface of the mounting base plate, and the distance between the two is greater than the opening diameter of the upper cover body.

[0025] Wherein, the fastener is a double-sided adhesive tape; and the designated electrical component is an electric power cabinet or an electric power communication shaft.

[0033] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] like Figures 1 to 4 As shown in the figure, an intelligent fire extinguishing device that can be installed and used immediately is proposed in an embodiment of the present invention, comprising a fire extinguishing composition 2, a heat ignition rod 3 and a temperature sensing detection line 4; wherein,

[0035] The fire extinguishing composition 2 is composed of metal salt particles, organic compounds and a binder for bonding the metal salt particles and the organic compound together; wherein the metal salt particles are a mixture of one or more components of potassium bicarbonate, potassium dihydrogen phosphate, sodium bicarbonate, potassium nitrate, strontium nitrate and dicyandiamide; the organic compound is a mixture of one or more components of dimethyl diamide, melamine, phenolic resin, hexamethylenetetramine, ammonium chloride and melamine polyphosphate; it should be noted that the fire extinguishing composition 2 is formed by grinding and crushing the metal salt particles and the organic compound as a whole, fixing them with a binder, and drying the bonded mixture at a low temperature;

[0036] At this time, the fire extinguishing composition 2 is filled in the closed shell 1, and when it burns, it automatically decomposes to produce aerosol fire extinguishing substances and is discharged to the outside of the closed shell 1 through the multiple first through holes 13 preset on the closed shell 1; it should be noted that the aerosol fire extinguishing substances decomposed by the fire extinguishing composition 2 under heat, specifically organic compounds, will produce nitrogen, carbon dioxide and other gases, and metal salt particles will produce a series of fire extinguishing particles (with a size of sub-nanometer level and can float); the closed shell 1 is a nylon glass fiber insulation flame retardant material component, and the multiple first through holes 13 provided thereon can be flexibly designed with a distribution pattern (such as array, equal spacing or other patterns), and the specific situation can be designed according to the actual environment, and the number of the first through holes 13 can be determined according to the overall size of the ready-to-install intelligent fire extinguishing device;

[0037] The hot ignition rod 3 has a self-ignition property, one end of which is located outside the closed shell 1 and connected to the temperature sensing detection line 4, and the other end extends into the closed shell 1 through a second through hole 14 preset on the closed shell 1 and is connected to the fire extinguishing composition 2, and it is driven to burn by the temperature sensing detection line 4 to ignite the fire extinguishing composition 2; it can be understood that the self-ignition temperature of the hot ignition rod 3 is a fixed value, and it automatically triggers combustion once the temperature transmitted from the temperature sensing detection line 4 is greater than its self-ignition temperature; at this time, the self-ignition temperature of the hot ignition rod 3 is preferably lower than the ignition temperature of the fire extinguishing composition 2, which can prevent the fire extinguishing composition 2 from burning before the hot ignition rod 3;

[0038] The temperature sensing detection line 4 is composed of a temperature detector and a heat-conducting metal wire; it can be understood that the heat-conducting metal wire of the temperature sensing detection line 4 has elasticity and angular bending properties, so as to adjust the temperature measurement direction to improve the detection of the surrounding temperature of the fire-prone point;

[0039] Among them, after the closed shell 1 is fixed in a designated electrical component (not shown, such as an electric cabinet or electric communication shaft with a small space, etc.), and at least one of the first through holes 13 thereon is set toward a specific fire-prone point (not shown) in the designated electrical component, if the fire-prone point catches fire, the temperature will be detected by the temperature sensing detection line 4 and transmitted to the heat ignition rod 3, so as to trigger the automatic combustion of the heat ignition rod 3 to drive the fire extinguishing composition 2 to burn and decompose to produce aerosol fire extinguishing substances, which are further released through each first through hole 13 to extinguish the fire-prone point; at this time, the automatic combustion of the heat ignition rod 3 is triggered when the self-ignition temperature of the fire-prone point exceeds the temperature detected and transmitted by the temperature sensing detection line 4 after the fire-prone point catches fire. It should be noted that the fire-prone point is determined by artificial experience and previous historical fire situations, and the temperature of the space where it is located when there is no fire will not exceed the natural temperature of the heat ignition rod 3;

[0040] In the embodiment of the present invention, the ready-to-use intelligent fire extinguishing device further includes: a wrapping cushion layer 5; wherein the wrapping cushion layer 5 is arranged in the closed housing 1 and wrapped around the outside of the fire extinguishing composition 2, and is provided with a plurality of holes for releasing the aerosol fire extinguishing substance generated by the combustion and decomposition of the fire extinguishing composition 2. At this time, the wrapping cushion layer is a high-melting-point porous insulating material component, which is beneficial to the heat preservation, moisture-proof and dust-proof of the fire extinguishing composition 2.

[0041] In the embodiment of the present invention, the ready-to-use intelligent fire extinguishing device further includes: an igniter 6 that can be remotely controlled; wherein the igniter 6 is connected to the middle of the hot ignition rod 3, and when receiving an external command, it instantly generates an ignition temperature that exceeds the self-ignition temperature of the hot ignition rod 3 to drive the hot ignition rod 3 to burn. The igniter 6 is composed of a receiving circuit (wireless), a decoding circuit, a relay circuit, an ignition circuit and a power supply module (such as Figure 4As shown). It can be understood that the igniter 6 is triggered by a remote sensing generator, and the signal generated by the remote sensing generator is recognized by the receiving circuit (wireless mode) to generate a control signal, which is decoded by the decoding circuit and transmitted to the ignition circuit, and the ignition circuit drives the heat initiation rod 3 to work.

[0042] In the embodiment of the present invention, in order to disassemble the closed housing 1 at the edge, the closed housing 1 is designed to be formed by sealingly connecting an upper cover 11 and a mounting base plate 12; wherein the upper cover 11 is in a semi-enclosed structure, a plurality of first through holes 13 are opened on its bottom wall, a second through hole 14 is opened on one side wall thereof, and a cavity is formed between the bottom wall and all side walls, the cavity opening toward the mounting base plate 12 and used to accommodate the wrapped cushion layer 5; it can be understood that the fire extinguishing composition 2 and the heat ignition rod 3 are also located in the cavity;

[0043] The upper surface of the mounting base plate 12 is sealed to cover the opening of the upper cover body 11 by means of a seal (not shown, such as a sealing gasket) and a locking mechanism (including a mechanical lock, a magnetic lock, etc.), and the lower surface is provided with a fastener (not shown, such as a double-sided tape, etc.) fixed to the designated electrical components. In one example, the locking mechanism includes two buckle plates 7 and two buckle rods 8 respectively cooperating with the two buckle plates 7, so that the upper cover body 11 and the mounting base plate 12 are fixed by the buckle plates 7 and the buckle rods 8; wherein the two buckle plates 7 are respectively fixed on the two opposite outer side walls of the upper cover body 12; the two buckle rods 8 are both fixed on the upper surface of the mounting base plate 12, and the distance between the two is greater than the opening diameter of the upper cover body 11. It should be noted that the structure and connection method of the buckle plates 7 and the buckle rods 8 are designed by conventional technical means in this field, which will not be repeated here.

[0044] The working principle of a ready-to-install intelligent fire extinguishing device in an embodiment of the present invention is to first determine the approximate position of a fire-prone point inside a designated electrical component (such as a power cabinet), and then turn the upper cover body 11 as a whole toward the electrical direction inside the designated electrical component, so that most of the multiple first through holes 13 are facing the fire-prone point, and then tear off the double-sided tape under the mounting base plate 12 and stick it to the surrounding position of the fire-prone point in the designated electrical component, and then press hard to ensure that the ready-to-install intelligent fire extinguishing device is firmly stuck.

[0045] Secondly, the temperature sensing detection line 4 is directly bound to a certain position slightly above the target area or is pulled out as a whole and then bound to a certain position slightly above the target area.

[0046] Then, keep the designated electrical component space in a relatively closed state. When the target area inside the designated electrical component is on fire and the fire temperature reaches the ignition temperature of the heat trigger rod 3, the temperature sensing detection line 4 will trigger the heat trigger rod 3 to self-ignite by transferring heat to the heat trigger rod 3, and drive the fire extinguishing composition 2 to burn through the burning heat trigger rod 3, so that the fire extinguishing composition 2 will be heated to decompose and produce a large amount of fire extinguishing substances (for example, organic compounds will produce nitrogen, carbon dioxide, etc., and metal salt particles will produce a series of fire extinguishing particles). At this time, the gaseous and fire extinguishing particles first pass through the holes on the wrapped cushion layer 5, and then use the first through hole 13 opened on the upper cover body 11 to release to the ignition point for fire extinguishing, specifically through nitrogen and carbon dioxide, etc., which can reduce the oxygen concentration in the combustion and play an auxiliary role. The fire extinguishing particles will undergo physical endothermic processes such as heat melting and gasification, absorb a large amount of heat at high temperature, and the flame temperature is greatly reduced, and then radiate to the combustion surface of the combustible material for gasifying the combustible molecules, and repeatedly consume a large amount of active groups, interrupt the combustible combustion chain, and achieve the purpose of active fire extinguishing.

[0047] In addition, when personnel discover that a fire has occurred at the ignition point but the initial temperature of the ignition point has not reached the auto-ignition temperature of the thermal initiator rod 3, a remote sensing generator can be used to generate a signal, which will be transmitted to the igniter 6 and then recognized by the internal receiving circuit (wireless mode) to generate a control signal. The signal will be decoded by the decoding circuit and transmitted to the ignition circuit, and then the ignition circuit will drive the thermal initiator rod 3 to burn, and the burning thermal initiator rod 3 will further ignite the fire extinguishing composition 2 to extinguish the fire.

[0048] Implementing the embodiments of the present invention has the following beneficial effects:

[0049] In the ready-to-install intelligent fire extinguishing device of the present invention, a fire extinguishing composition is filled in a closed shell. The hot ignition rod is driven to burn by a temperature sensing detection line connected to one end to ignite the fire extinguishing composition connected to the other end, which automatically decomposes to produce aerosol fire extinguishing substances and is discharged outside the closed shell to extinguish specific fire-prone points in designated electrical components (such as power cabinets, etc.). Therefore, fire can be extinguished in time when a fire occurs inside an electrical component with a small space, thereby overcoming the disadvantages of the manual triggering method of traditional fire extinguishing devices and the inability to extinguish fires in electrical components with a small space.

[0050] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
