Background
The aerosol fire extinguishing device has the characteristics of small volume, high fire extinguishing energy efficiency and no pollution, so that the device has been widely applied in the industries of electric power, energy sources and the like. At present, an aerosol fire extinguishing device mainly adopts a thermosensitive wire and/or an electronic ignition head as a starting device, and adopts a physical or chemical coolant as a cooling structure. When the conventional aerosol fire extinguishing device is designed, the internal structure of the device is compact, the heat-sensitive wire or the ignition head can be pressed by the coolant, and the heat-sensitive wire or the ignition head can be wrapped by the coolant under the pressing, so that the energy of the coolant can be reduced when the heat-sensitive wire or the ignition head is started, and the fire extinguishing device cannot be started.
In addition, because a large amount of gas can be generated when the aerosol fire extinguishing device is started, the internal pressure of the device is rapidly increased, the space on one surface of the coolant, which is closely attached to the aerosol generating agent, is narrow, and the local pressure is suddenly increased due to the large amount of gas, so that the risk of explosion of the device exists.

The utility model aims to solve the technical problems, and adopts the technical scheme that: the fire extinguishing device with the starting protector comprises an outer cylinder and a fire extinguishing agent grain arranged in the outer cylinder, wherein one end of the fire extinguishing agent grain is connected with the tail end of a starting part, a protective cover net is arranged at the tail end of the starting part, and a coolant is arranged between the outer side of the protective cover net and a nozzle.
Preferably, the protective cover net comprises a circular screen, and a supporting plate is arranged at the outer edge of the circular screen.
Preferably, protrusions are further arranged near the holes of the circular screen.
Preferably, the starting component is an electric ignition head or a thermosensitive wire structure.
Preferably, the end of the starting part is connected with one end of the fire extinguishing agent column through an ignition medicine bag.
Preferably, a silica gel sleeve for heat insulation is arranged on the inner side wall of the outer cylinder.

FIG. 2 is a schematic perspective view of the protective cover net of FIG. 1;
fig. 3 is a schematic top view of the structure of fig. 2 with a bump structure added.
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 3, a fire extinguishing device with a starting protector comprises an outer cylinder 1 and a fire extinguishing agent grain 2 arranged in the outer cylinder 1, wherein one end of the fire extinguishing agent grain 2 is connected with the tail end of a starting part 3, the tail end of the starting part 3 is provided with a protective cover net 4, and a coolant 5 is arranged between the outer side of the protective cover net 4 and a nozzle 10.
Preferably, the protective cover net 4 comprises a circular screen 4.1, and a supporting plate 4.2 is arranged at the outer edge of the circular screen 4.1. After the design, the fire extinguishing device can form a protective cover to protect the tail end of the starting part 3 (a thermosensitive wire or an ignition head), so that the energy of the coolant can not be reduced during starting, and the phenomenon that the fire extinguishing device cannot be started is effectively avoided.
Preferably, the round screen 4.1 is further provided with protrusions 6 near the openings. After the protrusions 6 are arranged, the cooling agent 5 contacted with the circular screen 4.1 can be effectively dispersed, and thus, the cooling agent 5 can be effectively prevented from blocking the screen holes of the circular screen 4.1.
Preferably, the starting part 3 is an electric ignition head or a heat-sensitive wire structure. In the present embodiment, when the starting member 3 is an electric ignition head structure, it is connected to a fire detecting device, which is a temperature sensor and/or a smoke sensor. When the conditions such as fire and overheat occur, the fire detecting device detects that the outside generates a high-temperature environment due to the fire, and then sends a signal to the microprocessor, and the microprocessor in the embodiment can select a 51 single-chip microcomputer, the model is an 80C51 single-chip microcomputer, or an STM32 microprocessor, the model is an STM32F103, and the microprocessor controls the starting component 3 to ignite the fire extinguishing agent grain 2. When the starting component 3 is of a thermosensitive line structure, the thermosensitive line structure is simpler, so that the fire extinguishing agent column 2 can be automatically started when a fire disaster occurs when the thermosensitive line is adopted, and the thermosensitive line can directly ignite the fire extinguishing agent column 2 without being matched with an additional fire disaster detection device and other external equipment.
Preferably, the end of the starting member 3 is connected to one end of the extinguishing agent column 2 through an ignition charge 7. In this embodiment, the ignition charge 7 may be ignited by the starting means 3 before the extinguishing agent column 2 is ignited by the ignition charge 7.
Preferably, the inner side wall of the outer cylinder 1 is provided with a silica gel sleeve 8 for heat insulation. The silica gel sleeve 8 can avoid the situation that the temperature of the outer cylinder 1 is too high in the fire extinguishing process.
Preferably, the front side of the outer cylinder 1 is provided with a front cover 9 in threaded fit with the front cover, a nozzle 10 is arranged on the surface of the front cover 9, the rear side of the outer cylinder 1 is provided with a rear cover 11 in threaded fit with the rear cover, and the rear cover 11 is provided with a through hole for penetrating the starting component 3.
Preferably, the rear cover 11 is connected to one side of the mounting frame 12 through bolts, and a mounting hole is formed in the other side of the mounting frame 12. So designed, the entire fire extinguishing apparatus can be quickly installed and removed by the installation frame 12.
The working principle of the embodiment is as follows:
when a fire occurs outside, the starting part 3 ignites the fire extinguishing agent grain 2, the fire extinguishing agent grain 2 in the embodiment is a grain pressed by aerosol generating agent, and the fire extinguishing agent grain 2 burns to generate fire extinguishing substances (such as aerosol or gas); after passing through the protective cover net 4, the fire extinguishing substance is cooled by the coolant 5 and then sprayed out from the nozzle 10, so that the temperature at the nozzle 10 of the fire extinguishing device is not too high; in this process, the protective cover net 4 provides enough space between the section of the starting of the fire extinguishing agent grain and the coolant, so that local pressure surge in the fire extinguishing device is avoided after the fire extinguishing agent grain is started, a certain buffering effect is provided, and a certain support is provided for the coolant 5, so that the energy of the starting structure is not reduced by the coolant.
