Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing device technology, and in particular to a non-pressurized piston-type perfluorohexanone fire extinguishing device. Background Technology

[0002] With the rapid development of society, electrical equipment is frequently seen in people's work and daily lives. As the equipment has been in operation for a longer period, the insulation materials of electrical components, cables, and other equipment gradually age, posing some safety hazards and potentially causing fires. Therefore, it is necessary to equip them with appropriate fire extinguishing devices, such as perfluorohexanone fire extinguishing systems.

[0003] Existing perfluorohexanone fire extinguishing devices have the following problems: perfluorohexanone residue remains in the device during operation, and some solid sediments in the smoke generated by the self-extinguishing insulation material layer do not spray out from the nozzle. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a non-pressurized piston-type perfluorohexanone fire extinguishing device in order to overcome the shortcomings of the existing technology.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a non-pressurized piston-type perfluorohexanone fire extinguishing device, comprising a long pipe and threaded joints A and B respectively screwed to both ends of the long pipe.

[0006] The inner cavity of the long tube forms a perfluorohexanone chamber. A piston B is filled at one end of the long tube near the threaded joint A. Piston B is embedded in piston A. Piston A has a slot to facilitate the discharge of excess gas during installation. The smoke generated by the self-extinguishing insulation material layer can squeeze the piston B and piston A device towards the nozzle.

[0007] The threaded connector A is screwed onto the outside of the long tube. The cavity at the end of the threaded connector A away from the long tube forms a chemical chamber. The chemical chamber contains, from the inside out, a self-extinguishing insulating material layer and an electric igniter. The electric igniter and the self-extinguishing insulating material layer are placed in close contact within the chemical chamber. The gas generated by the self-extinguishing insulating material layer pushes the piston, which can spray the perfluorohexanone liquid in the long tube out of the nozzle.

[0008] The threaded connector B is screwed into the long pipe. In the cavity of the threaded connector B near the end of the long pipe, an aluminum alloy rupture disc, a nylon gasket, and an internal hexagonal through-hole plug for limiting the position are placed in sequence from the inside to the outside.

[0009] Specifically, the aluminum alloy rupture disc has a C-shaped groove in the middle, making it more prone to rupture under pressure.

[0010] Furthermore, a terminal cap is screwed onto one end of the medicine compartment of the threaded connector A. The cavity at the end of the terminal cap away from the threaded connector A forms a sealed chamber. After the sealed chamber is filled with a silicone plug, a plug is screwed onto it.

[0011] The wire connecting the electric ignition head passes through the silicone plug and connects to the temperature control switch assembly. The silicone plug is used to prevent gas generated in the reagent compartment from escaping from the cap.

[0012] Furthermore, the temperature control switch assembly includes a temperature control switch, a circuit board, and a battery; the electric igniter is connected in series with the temperature control switch, the circuit board, and the battery via a wire. The temperature control switch closes upon sensing temperature to form a circuit, triggering the electric igniter to ignite the self-extinguishing insulating material layer. The self-extinguishing insulating material layer reacts to produce a large amount of gas, increasing the pressure in the agent chamber, breaking through the aluminum alloy rupture disc, and the gas compresses the piston device, spraying the perfluorohexanone liquid in the long tube out of the nozzle, achieving cooling and fire extinguishing effects.

[0013] Furthermore, a square end cap is screwed onto the end of the long tube furthest from the threaded joint B, and the square end cap is provided with spray holes. There are multiple spray holes, and when the device is started, the gas generated in the reagent chamber mixed with perfluorohexanone liquid is sprayed out from the spray holes.

[0014] Furthermore, a sealing ring A is provided at the connection between the long tube and piston B, and at the connection between piston B and piston A; a sealing ring B is provided at the connection between the long tube and threaded joint B. The sealing rings are provided to prevent leakage of perfluorohexanone liquid.

[0015] The beneficial effects of this invention are as follows: The piston design allows the smoke generated by the self-extinguishing insulating material layer to push the piston towards the nozzle, thus completely expelling the perfluorohexanone without leaving any residue. Simultaneously, the smoke is isolated by the piston, preventing any solid sediment from being ejected from the nozzle, resulting in a cleaner extinguishing agent. The device has a simple structure, is easy to manufacture and assemble, and requires no maintenance. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Figure 1 and Figure 2 The illustrated non-pressurized piston-type perfluorohexanone fire extinguishing device includes a long pipe 1 and threaded connectors A4 and B7 respectively screwed to both ends of the long pipe 1.

[0022] The inner cavity of the long tube 1 forms a perfluorohexanone chamber 101. The end of the long tube 1 near the threaded joint A4 is filled with a piston B43. The piston B43 is embedded with a piston A42. The piston A42 has a slot to facilitate the discharge of excess gas during installation. The smoke generated by the self-extinguishing insulation material layer can squeeze the piston B43 and piston A42 towards the nozzle.

[0023] Threaded connector A4 is screwed onto the outside of long pipe 1. The cavity at the end of threaded connector A4 away from long pipe 1 forms a chemical chamber 41. The chemical chamber 41 contains, from the inside out, a self-extinguishing insulating material layer 5 and an electric igniter 6. The chemical chamber houses the electric igniter and the self-extinguishing insulating material layer, which are in close contact. The gas generated by the self-extinguishing insulating material layer pushes a piston, which can spray perfluorohexanone liquid from the nozzle inside the long pipe.

[0024] The threaded connector B7 is screwed into the long pipe 1. In the cavity of the threaded connector B7 near the end of the long pipe 1, the aluminum alloy rupture disc 10 and the nylon gasket 91 are placed in sequence from the inside to the outside, and then the internal hexagonal through-hole plug 9 for limiting is screwed in.

[0025] The aluminum alloy rupture disc has a C-shaped groove in the middle, making it more prone to rupture under pressure.

[0026] One end of the medicine chamber 41 of the threaded connector A4 is externally screwed with a terminal cap 3. The cavity at the end of the terminal cap 3 away from the threaded connector A4 forms a sealed chamber 31. The sealed chamber 31 is filled with a silicone plug 21 and then externally screwed with a plug 2.

[0027] The wire 11 connecting the electric ignition head 6 passes through the silicone plug 21 and is connected to the temperature control switch assembly. The silicone plug is used to prevent gas generated in the medicine compartment from overflowing from the cap.

[0028] The temperature control switch assembly includes a temperature control switch 13, a circuit board 14, and a battery 12.

[0029] A square end cap 8 is screwed onto one end of the long pipe 1 away from the threaded joint B7. The square end cap 8 is provided with a spray hole 81. There are multiple spray holes 81. When the device is started, the gas generated in the reagent chamber is mixed with perfluorohexanone liquid and sprayed out from the spray holes.

[0030] A sealing ring A44 is provided at the connection between long pipe 1 and piston B43, and at the connection between piston B43 and piston A42; a sealing ring B71 is provided at the connection between long pipe 1 and threaded joint B7. These sealing rings are provided to prevent leakage of perfluorohexanone liquid.

[0031] The electric igniter 6 is connected in series with the temperature control switch 13, the circuit board 14 and the battery 12 via the wire 11. The temperature control switch 13 closes when it senses the temperature to form a circuit, triggering the electric igniter 6 to ignite the self-extinguishing insulating material layer 5. The self-extinguishing insulating material layer reacts to produce a large amount of gas, which increases the pressure in the agent chamber, breaks through the aluminum alloy rupture disc, and the gas squeezes the piston device, spraying the perfluorohexanone liquid in the long tube out of the nozzle to achieve the cooling and extinguishing effects.

[0032] The smoke generated by the self-extinguishing insulation material layer can squeeze the piston device towards the nozzle, thereby completely pushing out the perfluorohexanone by the piston device without any residue; at the same time, the smoke is isolated by the piston device, and some solid sediment will not be ejected from the nozzle, making the extinguishing material of the device cleaner.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
