Detailed Description
The utility model is described in further detail below with reference to the drawings and the specific examples.
As shown in fig. 1 to 4, the gas-generating driving type perfluorinated hexanone fire extinguishing device comprises a shell 1, wherein a perfluorinated hexanone fire extinguishing agent 3 coated by a single flexible material 2 is arranged in the shell 1, a gas generating agent 4 is arranged between the flexible material 2 and the rear end of the shell 1, and a nozzle 5 is arranged at the front end of the shell 1. The utility model sets up single flexible material 2, can be under the gas pressure that produces by the gas generator 4 and the extrusion effect of spout 5, and if use a plurality of flexible material 2 to cover the perfluorinated hexanone fire extinguishing agent 3, can exist a plurality of flexible material 2 soft contact points that contact, can form the buffering easily, thus flexible material 2 is difficult to be extruded and broken, because the utility model uses single flexible material 2, so the position (for example lateral wall, spout etc.) that contacts with flexible material 2 is the hard contact point, can be extruded and broken more easily, guarantee the normal blowout of perfluorinated hexanone fire extinguishing agent 3.
Preferably, the gas generating agent 4 is connected to one end of the activating member 6.
Preferably, the other end of the actuating member 6 passes through the rear cover 7, and the rear cover 7 is in threaded connection with the rear end of the housing 1.
Preferably, the flexible material 2 is a rubber sleeve or a silica gel sleeve or a plastic sleeve or an aluminum foil sleeve structure. The flexible material 2 can well seal the perfluorinated hexanone fire extinguishing agent 3 in the normal storage process, and can be extruded by high-pressure gas to break in the fire extinguishing process, thereby ensuring the normal spraying process of the perfluorinated hexanone fire extinguishing agent 3.
Preferably, the gas generating agent 4 is an aerosol generating agent. The aerosol generating agent can generate a large amount of aerosol or gas after being ignited, thereby generating large pressure and pushing the perfluorinated hexanone extinguishing agent 3 coated by the flexible material 2 to move towards the direction of the nozzle 5.
In addition, the utility model can further ensure that the flexible material can be normally broken under the gas pressure generated after the gas generating agent is ignited by the following embodiments, thereby ensuring the normal spraying of the perfluorinated hexanone.
Example 1: the thickness of the flexible material 2 at the end near the spout 5 is thinner than the thickness at the end near the spout 5. After the design, the directional cracking process can be realized, and the flexible material 2 is easier to crack from one end of the flexible material, which is close to the nozzle 5, due to different thickness, so that the normal spraying of the perfluorinated hexanone extinguishing agent 3 is ensured.
Example 2: as shown in fig. 2, the position of the flexible material 2 close to the nozzle 5 is also provided with a nozzle 8, and a pressure release membrane 9 is arranged in the nozzle 8. After the design, after the flexible material 2 is extruded, pressure reaches a certain degree, the pressure release diaphragm 9 can break, so that the perfluorinated hexanone fire extinguishing agent 3 is sprayed from the position of the pressure release diaphragm 9, and the process of breaking under the corresponding pressure value can be better controlled by selecting the pressure release diaphragms 9 with different materials.
Example 3: as shown in fig. 3 and 4, a stop block 10 is arranged on the inner wall of the cavity between the front end of the shell 1 and the flexible material 2. After the design, the stop block 10 can be used as a hard contact point with the flexible material 2, and when the flexible material 2 is extruded, the stop block 10 is more easily broken from a contact position with the stop block 10, so that the normal spraying of the perfluorinated hexanone extinguishing agent 3 is ensured.
Preferably, the number of the stoppers 10 is plural.
Preferably, the actuating member 6 is an electric ignition head or a heat-sensitive wire structure. In this embodiment, when the starting member 6 is of an electric ignition head structure, it is connected to a fire detection device, which is a temperature sensor and/or a smoke sensor. When fire, overheat and other conditions occur, the fire detection device detects the high temperature environment generated by the fire, and then sends a signal to the microprocessor, and the microprocessor controls the starting component 6 to ignite the gas generating agent 4. When the starting component 6 is of a thermosensitive wire structure, the thermosensitive wire structure is simpler, so that the thermosensitive wire can be automatically started when a fire disaster occurs, and the thermosensitive wire directly ignites the gas generating agent 4 without matching with an additional fire disaster detection device and other external equipment.
The working principle of the embodiment is as follows:
when a fire occurs outside, the starting component 6 ignites the gas generating agent 4, the gas generating agent 4 (aerosol generating agent is adopted in the embodiment) burns to generate a large amount of aerosol or gas, so that the perfluorinated hexanone fire extinguishing agent 3 coated by the flexible material 2 is pushed to move to the area where the nozzle 5 is located, when the pressure in the device reaches a certain degree, the flexible material 2 is extruded to break, so that the perfluorinated hexanone fire extinguishing agent 3 is released, and the fire extinguishing process is carried out by being sprayed out from the nozzle 5.
The above embodiments are merely preferred embodiments of the present utility model, and should not be construed as limiting the present utility model, and the embodiments and features of the embodiments of the present utility model may be arbitrarily combined with each other without collision. The protection scope of the present utility model is defined by the claims, and the protection scope includes equivalent alternatives to the technical features of the claims. I.e., equivalent replacement modifications within the scope of this utility model are also within the scope of the utility model.
