Description

Technical Field

[0001] This utility model relates to the fields of mechanical manufacturing and fire extinguishing cannon technology, specifically, to a portable forest fire extinguishing cannon. Background Technology

[0002] Currently, forest fires are complex, especially cliff fires. Due to the treacherous terrain, it is difficult or even impossible for personnel to approach quickly, making it difficult to suppress the fire in time. This can easily lead to the fire spreading and further escalating, posing great challenges to rescue efforts.

[0003] In existing technologies, traditional rescue methods include aerial operations using helicopters, but this method is costly. Using traditional artillery to fire extinguishing shells for long-range forest fire fighting is hampered by the heavy equipment, requiring specialized vehicles for transport, slow deployment speed, and poor adaptability due to complex forest terrain. Existing portable long-range forest fire extinguishing devices suffer from simple structures and measurement systems, poor accuracy, and the use of explosive extinguishing shells to release the extinguishing agent, which can easily cause the fire to spread due to the shockwave. Furthermore, the use of proximity fuses results in poor extinguishing effectiveness.

[0004] In summary, at least one of the following technical problems exists:

[0005] Traditional firefighting methods suffer from high rescue costs, long deployment times, poor environmental adaptability, poor accuracy, poor fire extinguishing effect, and a tendency to cause secondary spread of fire. Utility Model Content

[0037] Portable forest fire extinguishing cannon working process:

[0038] Firefighters arrived near the fire and selected a relatively flat area as the launch site, taking launcher 3 out of their backpacks.

[0039] Take the launch tube 2 out of the packaging box and install it on the launcher 3. Adjust the launcher 3 base 15 by adjusting the launcher 3 angle adjustment mechanism 17. When the level bubble is in the center position, it indicates that the base 15 has been leveled.

[0040] Record the initial tilt angle value of the tilt sensor 11 on the launch tube 2. The angle along the axial direction of the launch tube 2 is the value measured by the tilt sensor 11 along the OX axis, and is recorded as α. The angle perpendicular to the axial direction is the value measured by the tilt sensor 11 along the OY axis, and is recorded as β.

[0041] Rotate the launcher 3 and adjust the elevation adjustment mechanism 14 of the launcher 3 to adjust the elevation angle of the launch tube 2. Initially aim at the fire source through the launch tube 2, and fine-tune the elevation adjustment mechanism 14 of the launcher 3 to make the crosshair of the launch tube 2 accurately aim at the fire source.

[0042] Use rangefinder 5 to measure the distance l between the nozzle of launch tube 2 and the ignition point.

[0043] Read the measurement value of the tilt sensor 11OX, which is the aiming angle γ.

[0044] The computer software calculates the firing parameters based on the above data. The calculation principle is as follows:

[0045] Establish a launch coordinate system and calculate the coordinates (X1, Y1, Z1) of the ignition point in the launch coordinate system;

[0046] Establish a geodetic coordinate system. Based on the initial tilt angle of launch tube 2, transform the coordinates of the ignition point in the launch coordinate system into coordinates (X2, Y2, Z2) in the geodetic coordinate system. The transformation formula is as follows:

[0047]

[0048] Among them, α - the X-axis measurement value of tilt sensor 11; β - the OY-axis measurement value of tilt sensor 11; X1 - the X-coordinate of the ignition point in the launch coordinate system converted to the earth coordinate system; Y2 - the Y-coordinate of the ignition point in the launch coordinate system converted to the earth coordinate system; Z2 - the Z-coordinate of the ignition point in the launch coordinate system converted to the earth coordinate system.

[0049] The firing parameters are calculated in the horizontal coordinate system.

[0050] The firing parameters in the horizontal coordinate system are transformed into firing parameters in the launch coordinate system, including the launch angle δ and the fuse binding parameter t.

[0051] Adjust the setting parameter of fuse 7 to t, and put fire extinguishing bomb 1 into launch tube 2.

[0052] Adjust the elevation angle adjustment mechanism 14 of the launcher 3 to adjust the elevation angle of the launch tube 2 to the launch angle δ.

[0053] The ignition harness 19 is connected to the ignition power supply 18 and the rocket section 9 of the fire extinguishing bomb 1 respectively. The ignition power supply 18 provides an ignition current signal, and the fire extinguishing bomb 1 is launched from the launch tube 2.

[0054] Fire extinguishing bomb 1 flies through the air along a predetermined trajectory. When the flight time reaches the setting parameter t of fuse 7 or when fire extinguishing bomb 1 touches the mountain at the point of fire, fire extinguishing bomb 1 sprays fire extinguishing agent to suppress the fire.

[0055] Observe the landing point of fire extinguishing grenade 1 and the spraying time of fire extinguishing agent. If it is necessary to adjust the landing point of fire extinguishing grenade 1 or the spraying time of fire extinguishing agent, make corrections through the calculation computer and recalculate the firing data.

[0056] Repeatedly adjust the timing of fuse 7, insert fire extinguishing shell 1 into the tube, adjust the firing angle, and fire fire extinguishing shell 1.

[0057] Once the firefighting mission is complete, the system will be dismantled, and the fire extinguisher will be packed into a box and backpack.

[0058] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0059] The portable forest fire extinguishing cannon is a long-range firefighting device developed to address the complexities of forest fires, the difficulty for firefighters to approach the fire, and the inherent risks to their safety. It can launch fire extinguishing projectiles at long distances, precisely delivering the extinguishing agent via spraying. The release process produces no lethal fragments or shockwaves, preventing secondary fire spread. Employing a time-controlled and impact-detonated fuse, the extinguishing agent spraying time is controllable, improving firefighting efficiency. It features convenient portability, simple operation, effective firefighting, and operational safety. It is particularly suitable for medium- to long-range firefighting in complex terrain where firefighters cannot reach, such as cliff fires, solving the problems of "out of reach" and "unreachable targets," achieving separation of personnel and fire, and ensuring the safety of firefighters.
