Abstract
The fire type indirect starting aerosol fire extinguishing device comprises a hollow cylindrical shell, wherein a diaphragm is arranged in the middle of the shell, the diaphragm divides the inner space of the shell into a starting cavity and a fire extinguishing cavity, and the fire extinguishing cavity is filled with excitation medicament and aerosol grains from top to bottom; an actuating device for striking the diaphragm is arranged in the actuating chamber. The utility model provides a percussion type indirect starting aerosol fire extinguishing device which has good waterproof and dustproof performances and can meet the IP67 grade requirement in sealing performance. The conversion from the traditional direct-activated form to the indirect-activated form allows the cartridge to be completely sealed.
Description
Technical Field
The utility model relates to the technical field of fire protection, in particular to a firing type indirect starting aerosol fire extinguishing device.
Background
In the prior art, because the gap at the outlet of the thermosensitive wire is larger, the whole sealing performance of the device can not reach the IP67 level, and the starting reliability in extreme environment is greatly reduced. Therefore, a hot start device with higher sealing performance, less influence from external environment and stable starting performance needs to be developed.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a percussion type indirect starting aerosol fire extinguishing device which can extinguish fire under the condition that aerosol grains are completely sealed.
In order to solve the technical problems, the utility model adopts the following technical scheme: the fire type indirect starting aerosol fire extinguishing device comprises a hollow cylindrical shell, wherein a diaphragm is arranged in the middle of the shell, the diaphragm divides the inner space of the shell into a starting cavity and a fire extinguishing cavity, and the fire extinguishing cavity is filled with excitation medicament and aerosol grains from top to bottom; an actuating device for striking the diaphragm is arranged in the actuating chamber.
Preferably, the starting device comprises a hammer, one end of a thermosensitive wire is fixedly connected with the upper part of the hammer, and the other end of the thermosensitive wire is fixedly connected with the upper end of the shell and extends to the outside of the shell; a spring in a compressed state is provided between the hammer and the upper end of the housing.
Preferably, the lower end of the fire extinguishing cavity is opened, and a glue filling packaging layer is arranged at the bottom of the aerosol grain.
Preferably, the bottom of the hammer is of a conical structure.
Preferably, the diaphragm is made of stainless steel.
Preferably, the thickness of the diaphragm is 0.5mm.
The utility model provides a percussion type indirect starting aerosol fire extinguishing device which has good waterproof and dustproof performances and can meet the IP67 grade requirement in sealing performance. The conversion from the traditional direct-activated form to the indirect-activated form allows the cartridge to be completely sealed.
Drawings
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
FIG. 1 is a schematic diagram of the structure of the present utility model;
fig. 2 is an enlarged schematic view of the structure of the present utility model a.
Detailed Description
As shown in fig. 1-2, a percussion type indirect starting aerosol fire extinguishing device comprises a hollow cylindrical shell 1, wherein a diaphragm 2 is arranged in the middle of the inside of the shell 1, the diaphragm 2 divides the inside space of the shell 1 into a starting cavity 3 and a fire extinguishing cavity 4, and an excitation medicament 5 and an aerosol grain 6 are filled in the fire extinguishing cavity 4 from top to bottom; an activation device for striking the membrane 2 is provided in the activation chamber 3.
Preferably, the starting device comprises a hammer 7, one end of a thermosensitive wire 8 is fixedly connected with the upper part of the hammer 7, and the other end of the thermosensitive wire 8 is fixedly connected with the upper end of the shell 1 and extends to the outside of the shell 1; a spring 9 is provided in a compressed state between the hammer 7 and the upper end of the housing 1. The impact of the hammer 7 on the diaphragm 2 causes the excitation agent to be impacted, releasing heat, and creating a high temperature.
Preferably, the lower end of the fire extinguishing chamber 4 is opened, and a glue filling packaging layer 10 is arranged at the bottom of the aerosol grain 6.
Preferably, the bottom of the hammer 7 has a conical structure.
Preferably, the diaphragm 2 is made of stainless steel.
Preferably, the thickness of the diaphragm 2 is 0.5mm. Stainless steel has good stability and is easy to deform after being impacted.
When the device is used, the thermosensitive wire senses the external high temperature and then burns and breaks, the spring 9 in a compressed state releases energy at the moment of breaking, the spring 9 pushes the hammer 7 to move downwards, the hammer 7 impacts the excitation medicament 5 under the diaphragm 2, the excitation medicament 5 is impacted and then releases heat to generate high temperature, so that the aerosol cartridge 6 is started, and the medicament breaks through the encapsulating layer 10 and is sprayed out from the bottom of the shell 1.
The above embodiments are only preferred embodiments of the present utility model, and should not be construed as limiting the present utility model, and the scope of the present utility model should be defined by the claims, including the equivalents of the technical features in the claims. I.e., equivalent replacement modifications within the scope of this utility model are also within the scope of the utility model.
