[0041] Embodiment 1:

[0042] like Figure 1-Figure 7 As shown, a bracket magnetic fire extinguishing device includes a fire extinguishing device tank body 1, and also includes:

[0043] Nozzle 2, mounting bracket 3 and magnetic member 4;

[0044] The nozzle 2 is arranged at the bottom of the fire extinguishing device tank body 1, and the nozzle 2 sprays the fire extinguishing agent stored in the fire extinguishing device tank body 1;

[0045] The mounting bracket 3 is arranged to half-cover the fire extinguishing device tank body 1 , and the magnetic member 4 is fixedly mounted on the mounting bracket 3 . The fire extinguishing device tank body 1 is mounted and connected to the magnetic metal plate through the magnetic member 4 on the mounting bracket 3 .

[0046] The fire extinguishing device tank body 1 is cylindrical, and includes a tank body 11 and a neck interface 12 protruding outward from the tank body 11 , and the nozzle 2 is connected to the neck interface 12 .

[0047] Furthermore, the mounting bracket 3 includes a mounting plate 31, a restraining belt 32 and a clamp 33;

[0048] The mounting plate 31 is L-shaped and half covers the fire extinguishing device tank 1;

[0049] The binding belt 32 is disposed on the mounting plate 31 , and the binding belt 32 is disposed around the tank body 11 ;

[0050] The clamp 33 is installed on the mounting plate 31 , and a U-shaped opening 331 is provided on the clamp 33 to be clamped with the neck interface 12 , and the clamp 33 supports the fire extinguishing device tank 1 .

[0051] Furthermore, the mounting plate 31 includes a horizontally arranged top plate 311 and a vertically arranged side plate 312 , the top plate 311 and the side plate 312 are integrally connected, and the magnetic member 4 is mounted on the top plate 311 or the side plate 312 .

[0052] In addition, the restraining belt 32 includes a first steel belt 321, a second steel belt 322 and a buckle 323;

[0053] The first steel belt 321 and the second steel belt 322 are both installed on the side plate 312. The first steel belt 321 and the second steel belt 322 are arranged in an arc shape. The first steel belt 321 and the second steel belt 322 cooperate to hold the can body 11 tightly.

[0054] The buckle 323 is connected to the first steel belt 321 , and the buckle 323 is engaged with the upper hook portion 3221 of the second steel belt 322 to tighten the first steel belt 321 and the second steel belt 322 .

[0055] The fire extinguishing device tank body 1 of the utility model is a cylindrical tank body, and the volume of the fire extinguishing device tank body 1 is 1.2L or 2.48L respectively, and the filling density is ≤90%, so that the fire extinguishing device tank body 1 forms two specifications of fire extinguishing devices containing 1kg and 2kg of fire extinguishing agent. The fire extinguishing device is adsorbed on the metal top plate or side wall of the electric cabinet / cabinet through the mounting bracket 3 and the magnetic member 4. The magnetic member 4 is a strong permanent magnet, and the magnetic member 4 tightly fixes the fire extinguishing device tank body 1 on the top plate or side wall of the electric cabinet / cabinet 5.

[0056] It is further explained that the fire extinguishing agent selected is heptafluoropropane, but it is not limited to heptafluoropropane. All fire extinguishing agents that meet the fire extinguishing effect of the utility model are within the protection scope of the utility model.

[0057] When the fire extinguishing device is installed and connected using the mounting bracket 3, the mounting bracket 3 uses the restraining belt 32 to tie and fix the upper part of the tank body 11 of the fire extinguishing device tank body 1, and the clamp 33 is inserted and matched through the U-shaped mouth 331 to limit the neck interface 12 of the fire extinguishing device tank body 1, and then the clamp 33 is used to support the fire extinguishing device tank body 1, thereby realizing that the fire extinguishing device tank body 1 is directly fixed on the mounting bracket 3, and then the mounting bracket 3 is installed on the side wall or top plate of the electric cabinet / cabinet through the magnetic part 4. It should be emphasized that when installed on the side wall of the electric cabinet / cabinet, in order to prevent the fire extinguishing device from slipping, the mounting bracket 3 and the top plate of the electric cabinet / cabinet can be reinforced by a connecting piece.

[0058] When the fire extinguishing device tank body 1 is bundled with the binding belt 32, the first steel belt 321 and the second steel belt 322 are fastened by the buckle 323 and the hook portion 3221, and the first steel belt 321 and the second steel belt 322 are closed to cover and bundle the fire extinguishing device tank body 1.

[0059] The magnetic parts 4 are distributed on the four corners of the top plate 311 or the side plate 312. The magnetic parts 4 are strong magnetic parts and are fixed to the mounting bracket 3 by screws, thereby realizing the installation connection between the fire extinguishing device and the electric cabinet / cabinet.

[0060] Embodiment 2:

[0061] Embodiment 2 of the present invention is described with reference to Embodiment 1. The differences from Embodiment 1 are as follows:

[0062] like Figure 5 As shown, the nozzle 2 is provided with a glass bulb 21 for controlling the on and off of the nozzle 2 . The glass bulb 21 is filled with a liquid temperature-sensitive medium, and the glass bulb 21 bursts when the temperature reaches 68° C. to open the nozzle 2 .

[0063] The nozzle 2 is provided with an impact driver 22 for striking the glass bulb 21 , and the impact driver 22 is activated by thermal initiation or electrical initiation.

[0064] It should be noted that the utility model adopts multiple detection activation. The fire extinguishing device not only uses the glass bulb 21 to be activated by temperature-sensitive bursting, but also uses the impact driver 22 to break the glass bulb 21 to activate, thereby achieving the purpose of dual detection activation.

[0065] The liquid temperature-sensitive medium inside the glass bulb 21 is an alcohol mixture. When the temperature reaches 68°C, the liquid temperature-sensitive medium continues to expand, causing the glass bulb to expand and burst, thereby activating the fire extinguishing device. The liquid temperature-sensitive medium can select a suitable temperature (57 / 68 / 79 / 93 / 141°C) according to the installation environment.

[0066] In addition, the working principle of the impact driver 22 is:

[0067] In the standby state, the striker is kept in a pre-installed state by a pre-loaded spring or other mechanical energy storage element (such as rubber spring, compressed air, etc.). In this state, the force of the spring is restrained, and the striking part of the striker keeps a certain distance from the glass bulb to avoid accidental triggering.

[0068] The striker's restraint mechanism is released when the fire suppression system detects a preset trigger condition, such as temperature reaching a certain threshold, smoke or flame being detected. These conditions are usually detected by sensors connected to the system.

[0069] Once the trigger mechanism is activated, the locking device (which may be a screw, pin, magnet, or electronic lock, etc.) that restrains the striker spring is released. The released spring or compression energy quickly propels the striker forward, driving the striking part to strike the glass bulb.

[0070] In addition, the impact driver 22 may be provided with a chemical gas generating agent or gunpowder inside. When powered on and heated, the chemical gas generating agent or gunpowder generates high-pressure gas expansion, causing the impactor to impact the glass bulb.

[0071] The glass bulb ruptures upon impact, initiating a further chain reaction in the fire extinguishing system. In the case of an automatic sprinkler system, the ruptured glass bulb causes a change in water pressure or releases a mechanical blocker, which opens the nozzle of the fire extinguishing agent and begins to spray.

[0072] Embodiment 3:

[0073] Embodiment 3 of the present invention is described with reference to Embodiment 2. The differences compared with Embodiment 2 are as follows:

[0074] like Figure 6 As shown, when the impact driver 22 is triggered by heat, the impact driver 22 is connected to the thermistor 221, and the design temperature of the thermistor 221 is 175°C.

[0075] The thermistor is wound inside the electrical cabinet / cabinet for detection near a fire source. When there is a fire source near the thermistor, the thermistor will undergo physical changes when it reaches 175°C, such as melting, heating, breaking or deformation, thereby triggering the connected impact driver 22, and the impact driver 22 starts.

[0076] Since the thermistor wire can be distributed and wound inside the electrical cabinet / cabinet, its detection range is wider than that of the glass bulb, it is closer to the combustible material and the reaction is more sensitive.

[0077] Embodiment 4:

[0078] Embodiment 4 of the present invention is described with reference to Embodiment 2. The differences from Embodiment 2 are as follows:

[0079] like Figure 7 As shown, when the impact driver 22 is electrically triggered, the impact driver 22 is connected to the temperature / smoke alarm 222 via an intelligent control box, and the intelligent control box is integrated on the temperature / smoke alarm 222.

[0080] The temperature / smoke alarm 222 is a temperature or smoke alarm, or a combination of a temperature and smoke alarm. It monitors the temperature and smoke concentration inside the electrical cabinet / cabinet, and then sends an electrical signal to the fire alarm host 6. At the same time, it sends an electrical signal to the impact driver 22 through the intelligent control box. The impact driver 22 breaks the glass bubble to start the spraying, and then starts the fire extinguishing device. It should be emphasized here that the temperature / smoke alarm 222 can be connected to the impact driver 22 and the fire alarm host through a wired connection, or it can be connected using a wireless network.

[0081] In addition, the temperature / smoke alarm 222 has an infrared remote control intelligent detection function to facilitate maintenance and inspection. An energy-saving alarm light is provided on it. When working, the alarm light displays red for a short time, and during inspection, the alarm light displays blue for a short time. When on standby, the alarm light saves energy and does not light up. The temperature / smoke alarm 222 is equipped with a disposable lithium battery that can be on standby for 2 years.

[0082] Embodiment 5:

[0083] Embodiment 5 of the present invention is described with reference to Embodiment 1, and the differences compared with Embodiment 1 are as follows:

[0084] like Figure 5 As shown, a dispersion disk 23 is provided at the spray hole of the nozzle 2.

[0085] In order to facilitate the fire extinguishing device to spray out the fire extinguishing agent, the fire extinguishing agent is formed into an atomized state, covering the entire internal space of the electric cabinet / cabinet from the top downward, and then extinguishing the fire in the internal space of the cabinet to eliminate the fire.

[0086] Embodiment 6:

[0087] Embodiment 6 of the present invention is described with reference to Embodiment 1, and the differences compared with Embodiment 1 are as follows:

[0088] like Figure 5 As shown, a pressure gauge 24 is provided on the nozzle 2, and the pressure gauge 24 monitors the pressure inside the fire extinguishing device tank 1.

[0089] The pressure inside the fire extinguishing device tank body 1 can be monitored in real time by the pressure gauge 24 to avoid failure of the pressure inside the fire extinguishing device tank body 1 .

[0090] Embodiment 7:

[0091] Embodiment 7 of the present invention is described with reference to Embodiment 1, and the differences compared with Embodiment 1 are as follows:

[0092] like Figure 5 As shown, the nozzle 2 is provided with a filling interface 25 for filling fire extinguishing agent and nitrogen, and the filling interface 25 is provided with a charging locking switch 26 for controlling the switch of the filling interface 25 .

[0093] After the fire extinguishing agent in the fire extinguishing device tank body 1 is sprayed out, the triggering parts can be replaced, and then the fire extinguishing agent and nitrogen can be filled into the fire extinguishing device tank body 1 through the filling interface 25 for pressurization, and then the fire extinguishing device tank body 1 can be put into use again, and the charging locking switch 26 is used to lock the filling interface 25 to prevent the leakage of the fire extinguishing agent and nitrogen.

[0094] Embodiment 8:

[0095] Embodiment 8 of the present invention is described with reference to Embodiment 1, and the differences compared with Embodiment 1 are as follows:

[0096] like Figure 5 As shown, the nozzle 2 is provided with a mechanical pressure feedback device 27, which is connected to the main control room or the connected signal receiving module through a wired signal and then returns to the fire alarm host 6 of the building.

[0097] When the impact starter is started by a thermistor, a mechanical pressure feedback device 27 is provided on the nozzle 2 due to the lack of an alarm device. The working principle of the mechanical pressure feedback device 27 is that in the standby state, the two sets of metal contacts on the mechanical pressure feedback device 27 are not in contact, and when the fire extinguishing device starts to spray the fire extinguishing agent, or when a leak occurs inside the fire extinguishing device and the pressure changes, the two sets of metal contacts come into contact, triggering the mechanical pressure feedback device 27 to send out a set of passive dry contact signals, which are received by the main control room through the signal line, thereby activating the fire alarm to remind the staff of a fire or failure of the fire extinguishing device.

[0098] When using a smoke / temperature alarm, since a fire alarm host has been set up, the mechanical pressure feedback device 27 can be cancelled. The intelligent control box on the smoke / temperature alarm can directly prompt the fire alarm, and the pressure gauge 24 can also feedback the internal pressure condition of the fire extinguishing device for inspection and maintenance.

[0099] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
