Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting technology, in particular to a piston-type perfluorohexanone fire extinguishing device. Background Art

[0002] Perfluorohexanone is a new type of environmentally friendly fire extinguishing agent, known for its efficient fire extinguishing performance and environmental characteristics. It is a colorless and transparent liquid at room temperature and pressure, with a boiling point of approximately 49.2°C. When encountering a fire source, it can quickly evaporate into gas without leaving any residue. Secondly, the fire extinguishing mechanism of perfluorohexanone mainly includes three aspects: cooling the temperature of the burning material to below the ignition point, gas sinking to reduce the oxygen concentration around the fire source, and chemical inhibition.

[0003] Considering that perfluorohexanone is a liquid at room temperature and pressure, perfluorohexanone fire extinguishers usually use gas to push a piston, which pushes the perfluorohexanone in the bottle to spray toward the fire source to extinguish the fire. The existing method of pushing the piston movement is usually to ignite the agent to generate gas to push the piston movement. However, when the piston pushes out all the perfluorohexanone in the bottle, the generated gas will remain in the bottle and cannot play a role in extinguishing the fire, resulting in waste. Utility Model Content

[0004] In order to solve the problem of gas waste in existing perfluorohexanone fire extinguishers, the utility model provides a piston-type perfluorohexanone fire extinguishing device. The specific technical solution is as follows:

[0005] A piston-type perfluorohexanone fire extinguishing device comprises: a first-stage fire extinguishing assembly, which includes a perfluorohexanone storage bottle; and a second-stage fire extinguishing assembly, which includes a carbon dioxide storage bottle and a puncture piece. The carbon dioxide storage bottle can push the perfluorohexanone storage bottle to release the perfluorohexanone stored therein through the carbon dioxide stored therein. When the perfluorohexanone is completely released, the puncture piece can connect the carbon dioxide storage bottle with the perfluorohexanone storage bottle to release the carbon dioxide.

[0006] Furthermore, the first-stage fire extinguishing assembly also includes: a puncture piece arranged inside the perfluorohexanone storage bottle, the puncture piece forming a jet pipe connecting the outside world and the inside of the perfluorohexanone storage bottle; a sealing gasket arranged at the connection between the perfluorohexanone storage bottle and the carbon dioxide storage bottle, the sealing gasket can limit the mixing of carbon dioxide and perfluorohexanone, and the puncture piece can pierce the sealing gasket to exchange gas between the carbon dioxide storage bottle and the outside world.

[0007] Preferably, the first-stage fire extinguishing assembly further comprises: a piston arranged at one end of the perfluorohexanone storage bottle close to the carbon dioxide storage bottle, which piston can push the perfluorohexanone out of the perfluorohexanone storage bottle along the axial direction of the perfluorohexanone storage bottle under the push of carbon dioxide; and an end cap arranged at one end of the perfluorohexanone storage bottle close to the carbon dioxide storage bottle, the side of the end cap in contact with the perfluorohexanone storage bottle being a sealing edge.

[0008] Preferably, the second-stage fire extinguishing assembly further includes: a first pipe with an unopened end, the first pipe being capable of guiding carbon dioxide to push perfluorohexanone to be released to the outside; and an electric explosion valve arranged inside the first pipe, the electric explosion valve forming a structure for controlling the flow of carbon dioxide.

[0009] Preferably, the second-stage fire extinguishing assembly further comprises a through second pipe, which is formed by penetrating the unopened end of the first pipe, and the second pipe guides the carbon dioxide to be released to the outside through the perfluorohexanone storage bottle.

[0010] It can be seen from the above technical solution that the utility model has the following beneficial effects:

[0011] The utility model is provided with a carbon dioxide storage bottle to push the sealing gasket to push the piston, thereby pushing the perfluorohexanone to be released to the fire source for extinguishing the fire. Secondly, a piercing member is provided at the end position of the sealing gasket, that is, the rightmost end of the perfluorohexanone storage bottle, so that the piercing member can pierce the sealing gasket that has reached the end position to connect the carbon dioxide storage bottle and the perfluorohexanone storage bottle, so that the carbon dioxide can also be released to the fire source for extinguishing the fire, thereby improving the fire extinguishing efficiency and gas utilization rate of the utility model.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] In the description of the embodiments of the present invention, it should be noted that the terms "inside", "outside", "upper", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of the present invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0017] like Figure 1 As shown, an embodiment of the present invention includes: a first-stage fire extinguishing assembly 1, which includes a perfluorohexanone storage bottle 11; and a second-stage fire extinguishing assembly 2, which includes a carbon dioxide storage bottle 21 and a puncture member 15. The carbon dioxide storage bottle 21 can push the perfluorohexanone storage bottle 11 to release the perfluorohexanone stored therein through the carbon dioxide stored therein. When the perfluorohexanone is completely released, the puncture member 15 can connect the carbon dioxide storage bottle 21 with the perfluorohexanone storage bottle 11 to release carbon dioxide.

[0018] Specifically, liquid perfluorohexanone is placed in the perfluorohexanone storage bottle 11, and compressed liquid carbon dioxide is placed in the carbon dioxide storage bottle 21. When the liquid carbon dioxide inside is released, it quickly turns into gas to push the perfluorohexanone inside the perfluorohexanone storage bottle 11 to be released to the fire source. When it encounters the fire source, it will quickly turn into gas to extinguish the fire. Secondly, after all the perfluorohexanone is released to the outside, carbon dioxide is also released to the outside through the connecting port between the carbon dioxide storage bottle 21 and the perfluorohexanone storage bottle 11 under high pressure to extinguish the fire. Among them, carbon dioxide fire extinguishing mainly relies on the asphyxiation effect to achieve the purpose of fire extinguishing. When a large amount of carbon dioxide is sprayed into the combustion area, it will quickly diffuse and dilute the oxygen in the air, reducing the oxygen concentration to a level that is insufficient to maintain combustion, thereby preventing the combustion process. It is basically the same as the fire extinguishing scenario applicable to perfluorohexanone, so that this embodiment can not only avoid the waste of gas that pushes perfluorohexanone, but also realize a two-stage fire extinguishing structure to improve the fire extinguishing effect.

[0019] like Figure 2As shown, the first-stage fire extinguishing assembly 1 also includes a piston 12 arranged at one end of the perfluorohexanone storage bottle 11 close to the carbon dioxide storage bottle 21, and the piston 12 can push the perfluorohexanone out of the perfluorohexanone storage bottle 11 along the axial direction of the perfluorohexanone storage bottle 11 under the push of carbon dioxide; and an end cap 14 arranged at one end of the perfluorohexanone storage bottle 11 close to the carbon dioxide storage bottle 21, and the side of the end cap 14 in contact with the perfluorohexanone storage bottle 11 is a sealing edge.

[0020] Specifically, a piston 12 is slidably connected to the inside of the perfluorohexanone storage bottle 11, and the radial outer surface of the piston 12 is in close contact with its inner surface, dividing it into two independent spaces. The left space is connected to the carbon dioxide storage bottle 21 so that the carbon dioxide can push the piston 12 to move to the right, thereby compressing the right space, thereby releasing the perfluorohexanone in the right space to the external fire source for extinguishing the fire; secondly, an end cap 14 is welded to one end of the perfluorohexanone storage bottle 11 close to the carbon dioxide storage bottle 21, and the end cap 14 seals the left space so that the carbon dioxide that pushes the piston 12 to move will not leak to the outside, thereby increasing the release rate of perfluorohexanone and thereby increasing the fire extinguishing speed of the embodiment.

[0021] Furthermore, the first-stage fire extinguishing assembly 1 also includes: a piercing member 15 arranged inside the perfluorohexanone storage bottle 11, the piercing member 15 forming a jet pipe 16 connecting the outside world and the inside of the perfluorohexanone storage bottle 11; a sealing gasket 13 arranged at the connection between the perfluorohexanone storage bottle 11 and the carbon dioxide storage bottle 21, the sealing gasket 13 can limit the mixing of carbon dioxide and perfluorohexanone, and the piercing member 15 can pierce the sealing gasket 13 to exchange gas between the carbon dioxide storage bottle 21 and the outside world.

[0022] Specifically, the jet pipe 16 controls the connection between the perfluorohexanone storage bottle 11 and the outside world, and the carbon dioxide pushes the piston 12 and then pushes the perfluorohexanone to be released to the outside world through the jet pipe 16; secondly, the sealing gasket 13 is tightly fitted with one side of the piston 12, and its movement state is the same as that of the piston 12. A through hole for the puncture member 15 to pass through is formed in the central area of ​​the piston 12, but the sealing gasket 13 can prevent carbon dioxide from flowing into the perfluorohexanone storage bottle 11 and mixing with perfluorohexanone, thereby ensuring the efficiency of carbon dioxide in pushing the piston 12, and a sharp structure is formed on the end of the puncture member 15 pointing to the piston 12. When the piston 12 moves to the rightmost end of the perfluorohexanone storage bottle 11, that is, when all the perfluorohexanone is released, the sharp structure contacts the sealing gasket 13 and forms a through hole, thereby allowing the carbon dioxide storage bottle 21 to penetrate the perfluorohexanone storage bottle 11, thereby allowing carbon dioxide to pass through the through hole of the sealing gasket 13 and the perfluorohexanone storage bottle 11 and finally flow from the jet channel to the outside world to extinguish the fire.

[0023] Furthermore, the second-stage fire extinguishing assembly 2 also includes: a first pipe 22 with an unopened end, which can guide carbon dioxide to push perfluorohexanone to be released to the outside; and an electric explosion valve 24 arranged inside the first pipe 22, which has a structure for controlling the flow of carbon dioxide.

[0024] Specifically, the electric explosion valve 24 is a valve activated by an electrical signal. It is often used in situations that require a quick response and extremely high reliability. Its working principle is based on the action of electromagnetic force. When an electrical signal is received, the electromagnetic coil will generate a magnetic field, thereby driving the internal piston 12 or diaphragm to move, so that the valve is opened or closed. Explosive materials can be used to achieve instantaneous power transmission, thereby quickly opening or closing the valve; secondly, the first pipe 22 connects the carbon dioxide storage bottle 21 and the perfluorohexanone storage bottle 11, and the electric explosion valve 24 is arranged between the first pipe 22 to control the flow of gas therein, so that carbon dioxide pushes the unopened end of the first pipe 22, namely the sealing gasket 13, and then promotes the release of perfluorohexanone, so that the direction and speed of the carbon dioxide flow can be controlled, and the release rate of perfluorohexanone can be controlled, thereby improving the utilization rate of perfluorohexanone.

[0025] Furthermore, the second-stage fire extinguishing assembly 2 also includes a through second pipe 23 , which is formed by penetrating the unopened end of the first pipe 22 . The second pipe 23 guides carbon dioxide to be released to the outside through the perfluorohexanone storage bottle 11 .

[0026] Specifically, when the carbon dioxide pushes the sealing gasket 13 and the piston 12 to release all the perfluorohexanone, the unopened end of the first pipe 22, i.e., the sealing gasket 13, is close to the rightmost end of the perfluorohexanone storage bottle 11, so that the piercing member 15 can pierce the sealing gasket 13 so that the first pipe 22 forms a penetrating second pipe 23, and the carbon dioxide can be released to the outside along the second pipe 23 and the jet pipe 16 to extinguish the fire, thereby improving the fire extinguishing efficiency of this embodiment.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
