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 ternary battery prevention and control aerosol fire extinguishing device comprises a groove 2 attached in a ternary battery box 1, a medicament plate 3 is arranged in the groove 2, the outer surface of the medicament plate 3 is in contact with a starting explosive column 4, and the initiating end of a starting component 6 is connected with the starting explosive column 4. In the present embodiment, when the battery in the ternary battery case 1 heats or burns, the starting member 6 ignites the starting cartridge 4, and the heat generated by the combustion of the starting cartridge 4 causes the reagent plate 3 to burn to generate a large amount of fire extinguishing substances, thereby performing a fire extinguishing process inside the ternary battery case 1.
Preferably, the groove 2 is a cuboid shell structure with an open top, and is attached to the inner surface of the box cover 1.1 at the top of the ternary battery box 1. In this embodiment, after the groove 2 is attached to the case cover 1.1 of the ternary battery case 1, the replacement of the battery may not be affected, for example, when the battery is maintained and replaced or charged, the battery needs to be taken out, and the case cover 1.1 needs to be opened at this time, if the fire extinguishing device is in the ternary battery case 1, the possibility that the battery will collide with the fire extinguishing device when taken out or mounted needs to be considered, and after the fire extinguishing device is mounted to the case cover 1.1, the whole fire extinguishing device can be turned to one side by opening the case cover 1.1, so that the dismounting process of the battery is not affected.
Preferably, the outer surface of the medicament plate 3 is covered with a silicone layer 5. The silica gel layer 5 can play a role in heat insulation, a large amount of heat can be generated after the medicament plate 3 is ignited, and the heat can be prevented from generating open flame and deflagration energy in the ternary battery box 1 through the heat insulation effect of the silica gel layer 5.
Preferably, a mounting groove matched with the starting explosive column 4 is formed in the middle area of the outer surface of the medicament plate 3. By such design, the process of installing the explosive column 4 on the outer surface of the medicament plate 3 can be started conveniently.
Preferably, the medicament plate 3 has a plate-like structure formed by pressing aerosol generating agent powder, and the starting cartridge 4 has a cylinder structure formed by pressing aerosol generating agent powder. In the embodiment, the main components of the aerosol generating agent powder used by the agent plate 3 comprise 40% -47% (mass fraction) of potassium nitrate, and other components are phenolic resin, melamine and ferrocene, and the aerosol generating agent powder has the characteristics of good fire extinguishing effect, almost no open flame generated during combustion, but difficult to start; the main components of the aerosol generating agent powder used for starting the explosive column 4 comprise 60% -75% (mass fraction) of potassium nitrate, and other components are phenolic resin, melamine and ferrocene, and the aerosol generating agent powder has the characteristics of poor fire extinguishing effect, but is easy to start (ignite). Therefore, the starting grain 4 and the medicine plate 3 are matched for use, and the dual advantages of easy starting and good fire extinguishing effect can be achieved.
Preferably, the actuating member 8 is an electric ignition head or a heat-sensitive wire structure. In the present embodiment, the starting means 8 may perform a starting process on the starting cartridge 4 by means of electric ignition or by means of thermally sensitive wire ignition; when the actuating member 8 is of an electrical ignition head construction, the actuating member may be connected to a fire detection device (e.g. a temperature sensor and/or a smoke sensor); when the batteries in the ternary battery box 1 are in fire, overheat and the like, the fire detection 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 controls the starting component 8 to start the explosive column 4 to ignite. When the starting component 8 is in a thermosensitive line structure, the thermosensitive line structure is simpler, and when the thermosensitive line is adopted, the battery in the ternary battery box 1 can be directly ignited when fire, overheat and the like occur, and then the starting explosive column 4 is ignited.
The working principle of the utility model is as follows:
when the batteries in the ternary battery box 1 are in fire, overheat and the like, the starting part 6 ignites the starting explosive column 4, and the heat generated by the combustion of the starting explosive column 4 enables the medicament plate 3 to burn so as to generate a large amount of aerosol fire extinguishing substances, so that the fire extinguishing process is rapidly carried out in the ternary battery box 1; when the battery is maintained and replaced or charged, the battery needs to be taken out, the case cover 1.1 needs to be opened at the moment, the whole fire extinguishing device can be turned to one side by opening the case cover 1.1, and therefore the disassembly and assembly process of the battery cannot be influenced.
