Fire-retarding artillery shell
An artillery shell is fired out of a gun towards a fire. A trigger releases a fire-retarding material from the artillery shell to retard the fire.
1. An artillery shell comprising:
an external surface;
a cavity disposed within the external surface;
a fire-retarding material disposed within the cavity; and
a trigger configured to release the fire-retarding material, wherein the trigger is configured to mechanically open the external surface, and wherein the trigger comprises:
an interface configured to connect to the external surface;
at least one arm configured to open the external surface; and
a device comprising a timer, an altimeter, an accelerometer, a global positioning device, a temperature sensor, a pressure sensor, or a distance measuring device which is configured to determine when the at least one arm opens the external surface.
2. The artillery shell of claim 1 , wherein the trigger further comprises a rod and a sliding device disposed over the rod, wherein the at least one arm is moveably attached to the rod.
3. The artillery shell of claim 2 , wherein the at least one arm is pivotally attached to the rod.
4. The artillery shell of claim 2 , wherein when the sliding device is in a first position the at least one arm is in a retracted position and configured to not open the shell, and when the at least one arm is in a second position the at least one arm is in an extended position and configured to open the shell.
5. The artillery shell of claim 4 , wherein the trigger further comprises:
a spring disposed over the rod, wherein the spring is configured to prevent the sliding device from moving from the first position to the second position until the device releases the spring from the sliding device allowing the sliding device to move to the second position.
6. A fire-fighting system comprising:
a gun; and
an artillery shell which is configured to be fired out of the gun, wherein the artillery shell comprises:
an external surface;
a cavity disposed within the external surface; a fire-retarding material disposed within the cavity; and
a trigger configured to release the fire-retarding material, wherein the trigger is configured to mechanically open the artillery shell, the trigger comprising:
an interface configured to connect to the artillery shell;
at least one arm configured to open the artillery shell; and
a device comprising a timer, an altimeter, an accelerometer, a global positioning device, a temperature sensor, a pressure sensor, or a distance measuring device which is configured to determine when the at least one arm opens the artillery shell.
7. The fire-fighting system of claim 6 , wherein the trigger further comprises a rod and a sliding device disposed over the rod, wherein the at least one arm is moveably attached to the rod.
8. The fire-fighting system of claim 7 wherein the at least one arm is pivotally attached to the rod.
9. The fire-fighting system of claim 7 , wherein when the sliding device is in a first position the at least one arm is in a retracted position and configured to not open the artillery shell, and when the at least one arm is in a second position the at least one arm is in an extended position and configured to open the artillery shell.
10. The fire-fighting system of claim 9 , wherein the trigger further comprises a spring disposed over the rod, wherein the spring is configured to prevent the sliding device from moving from the first position to the second position until the device releases the spring from the sliding device allowing the sliding device to move to the second position.
