At present, because forest fires frequently occur and the fire is rapidly developed, a plurality of uncertain dangers are brought to fire extinguishing and rescue work. The ground cluster bomb is adopted to carry out long-distance fire extinguishing, so that casualties can be effectively avoided. Before the fire extinguishing bomb on the ground is launched, the power supply device of the bomb body needs to be started, and the battery cabin is a device for providing required electric energy for the bomb body.
Among the existing elastomer power supply devices, lithium batteries are the most common. However, the lithium battery is stored for a long time, self-discharge is easy to occur, the electric quantity of the battery is insufficient after the discharge, and the electric energy required by the projectile body for launching the projectile body cannot be reliably provided after a fire disaster occurs. Thereby delaying the opportunity of fire fighting and causing irreparable loss to the society. Meanwhile, the projectile body is provided with the initiating explosive device, and if the projectile body cannot work normally, huge dangerous hidden dangers are caused for projectile body recovery or projectile body destruction.

When the projectile body is stored, the thermal battery is not used, and when the projectile body needs the power supply device to provide electric energy, the thermal battery starts to react and act after the power-on switch arranged on the battery cabin body is opened, and the thermal battery discharges outwards. Thus, the thermal battery can provide the projectile with its necessary electrical energy reliably without the projectile powering means being affected by the storage time.
In order to adapt to the working environment of the thermal battery, a thermal insulation sleeve made of bakelite rubber materials is used for storing the thermal battery. Three cavity structures are evenly distributed in the heat insulation sleeve, and a thermal battery is stored in each cavity, so that the heat insulation and magnetic isolation effects among the thermal batteries are realized. The top of the heat insulation sleeve is provided with a wiring groove for outgoing lines of the thermal batteries, and the outgoing lines of each thermal battery are concentrated into a wiring harness groove of a semicircular notch on the side edge of the heat insulation sleeve through the wiring groove and are connected with a full-elastic power supply line. In order to ensure the firmness of the thermal battery assembly, the gaps between the thermal battery and the cavity of the heat insulating sleeve and the top of the thermal battery are filled with flexible heat-resistant materials. The heat insulating sleeve is fixed at the bottom of the battery compartment shell through the long screw, so that the pressure generated by the whole heat insulating sleeve and the thermal battery when the projectile body is launched acts on the battery compartment shell, and the heat insulating sleeve and the thermal battery are supported by the battery compartment shell so as to ensure that the heat insulating sleeve structure and the thermal battery do not generate relative stress and move during launching, and maintain the original structure unaffected.
The bottom of the battery compartment shell is provided with a square groove for positioning the thermal battery, and the square groove is used for positioning the assembly direction of the thermal battery. The square groove and the semicircular groove on the heat insulation sleeve are respectively aligned with the square groove and the semicircular groove at the bottom of the shell, and the three separation cavities on the heat insulation sleeve are respectively aligned with the three thermal batteries. The lead wire on the thermal battery and the full-elastic wire harness are connected with the upper cabin section and the lower cabin section through the semicircular groove of the battery cabin. The heat insulation sleeve is sequentially provided with a cover plate, a magnetic insulation pad, a circuit board and geomagnetism.
The battery compartment is internally provided with a circuit board for controlling the full-bullet electric appliance and a geomagnetic device for measuring the posture of the bullet body. The circuit board is fixed on the cover plate provided with the magnetic isolation pad through screws after being subjected to plastic packaging. In order to not influence the working performance of the geomagnetism, a special magnetism isolating pad is added between the cover plate and the circuit board besides the heat insulation sleeve made of the bakelite rubber. The geomagnetic device is fixed on the cover plate by using a screw. The connection stud is adopted between the geomagnetic device and the circuit board for positioning, and the reasonable distance between the circuit board and the geomagnetic device is ensured.
The power-on switch is installed from a square opening at the bottom end of the battery compartment shell, the round head part of the switch is fixed on the shell of the battery compartment, and the switch is screwed up and fixed from the outside of the battery compartment shell by using screws.
Has the advantages that:
1. the battery compartment structure of the ground fire extinguishing bomb disclosed by the invention uses the thermal battery as a power supply of a body of the fire extinguishing bomb, the thermal battery is not activated and does not discharge, replacement is not needed, the storage time is long, and the effect is reliable.
