Problems solved by technology

[0004] No matter what kind of automatic fire extinguishing equipment, there are limitations in the actual application range, such as: temperature detection and / or smoke detector, solenoid valve control automatic fire extinguishing equipment, in larger warehouses, temperature detection and / or smoke detectors Sensors can only be installed on walls, pillars, and beams on the top of warehouses. Once a burning point appears far away from walls, pillars, and beams, the temperature or dense smoke will be transmitted to temperature detection and / or smoke detectors. For a certain period of time, the burning point cannot be extinguished in time
Another example: the glass bubble is used as a fire extinguishing device for sealing the nozzle. When the glass bubble is far from the burning point, it cannot be broken in time, and the fire cannot be extinguished in time.

Embodiment 1

[0027] Such as figure 1 , figure 2 As shown, in the case of direct contact with the burning point, the membrane rupture device is a sealing pressure-resistant film 7, and the sealing pressure-resistant film is arranged between the sealing film and the sealing component, and is made of heated combustible metal.

[0028] Utilizing the phenomenon that combustible metals burn when heated, the sealing film is burned through by burning, and the fire extinguishing material stored in the pressure vessel can be ejected from the top of the ceramic cap to realize automatic triggering.

[0029] Further, the sealing pressure-resistant film is made of metal such as magnesium sheet, or magnesium alloy sheet, or conductive titanium powder compressed sheet, or titanium sheet, or titanium alloy sheet, or aluminum sheet, or tin sheet. The best solution is magnesium flakes. 38°C-40°C is the ignition point of magnesium. Magnesium can burn in carbon dioxide. The metal strength is similar to gold ...

Embodiment 2

[0032] Such as Figure 1 to Figure 5 As shown, in the case of direct contact with or relatively close to the burning point, the membrane rupture device can also be a temperature-sensitive puncturing assembly 8, which includes a heat-deformed deformed metal part 81 and an acupuncture part 82; The acupuncture part points to and is close to the sealing film, the top of the acupuncture part is detachably connected to the bottom of the deformed metal part, and the deformed metal part is fixed by a metal bracket arranged on the top of the spout; the deformed metal part can be A deforming movement is generated towards the sealing film, and the needling part is able to pierce the sealing film.

[0033] Among them, after the deformed metal part is heated, it is blocked by the metal bracket and moves toward the deformation of the sealing film. The acupuncture part connected with the deformed metal part begins to move towards the sealing film and finally pierces the sealing film; the sea...

Embodiment 3

[0039] On the basis of the foregoing embodiment 2, as Figure 1 to Figure 5 As shown, this embodiment proposes an improved technical solution.

[0040] The membrane rupture device is a temperature-sensitive puncture component with a temperature control circuit; the temperature control circuit is connected to both ends of the deformable metal part through two wires; the deformable metal part is energized and generates heat and can generate deformation movement to the sealing film, The needling parts are able to pierce the sealing membrane.

[0041] When the flame burns, the heat or smoke rises upwards, but the horizontal temperature control diffusion or smoke diffusion is slow; if the fire extinguishing equipment is set in parallel with the burning point, at this time, the temperature control circuit set above the burning point can be used to detect the presence of fire. At the burning point, the power frequency voltage is controlled by the temperature control circuit to condu...

Abstract

The invention relates to a fire extinguisher, specifically an automatic trigger fire extinguisher, comprising a membrane breaking device capable of breaking a sealed film; the membrane breaking device is a sealed pressure-resistant film, or the membrane breaking device is a temperature-sensitive puncture component , or the membrane rupture device is a temperature-sensitive puncture assembly with a temperature control circuit, or the membrane rupture device is a plasma high-temperature discharge assembly, or the membrane rupture device includes a sealing pressure-resistant film, a temperature-sensitive puncture assembly and The comprehensive membrane breaking device of the plasma high-temperature discharge component; it can automatically trigger the burning membrane breaking, piercing membrane breaking, and breakdown membrane breaking of the sealing film, so as to realize automatic fire extinguishing. Realize the voltage lower than 5V to control valve opening and fire extinguishing, and can be directly connected to the control circuit lower than 5V. The technical solution of the invention is widely used in the detection range of the combustion point, has a simple structure, low manufacturing and use costs, is suitable for fire protection engineering in many fields in reality, and is easy to popularize.

Description

technical field [0001] The invention relates to a fire extinguisher, in particular to an automatic trigger fire extinguisher. Background technique [0002] Fire extinguishing equipment is an important equipment in the event of a fire, especially automatic fire extinguishing equipment. By placing it in public facilities, industrial and mining enterprises, aerospace railway ships, buildings and other environments, it can immediately extinguish the burning point and avoid further expansion of the fire. [0003] Automatic fire extinguishing equipment in the prior art is roughly divided into two ways to trigger automatic fire extinguishing. One is to use electronic equipment, such as temperature detection, smoke detectors, etc., to detect the occurrence of a fire, so as to open the solenoid valve switch of the automatic fire extinguishing device, so that the fire extinguishing material is sprayed out, and the other is to use glass bubbles similar to thermometers as the nozzles of...
