Technical field

The present invention relates to the technical field of fire extinguishing equipment, and in particular to a multi-bomb fire extinguishing platform and a fire extinguishing method thereof.

Background technique

The muzzle speed of various existing fire-extinguishing projectiles depends on the launch energy and projectile weight. Since the muzzle speed of fire-extinguishing projectiles cannot be adjusted, the ranges of different projectile types (with different projectile weights) cannot be unified and cannot reach the same impact point. That is, only a single type of ammunition can be used at the same fire scene at the same time, which cannot meet the requirements of efficient fire extinguishing.

Specifically, due to the different densities of fire extinguishing agents with different properties (such as dry powder, water-based fire extinguishing agents), different types of fire extinguishing bombs have different weights. If they are launched from the same launch platform, they will be ejected from the same launch angle. Fire extinguishing bombs cannot reach the same impact point.

The comprehensive effectiveness of various fire extinguishing agents increases the flexibility of fire extinguishing operations and greatly improves the fire extinguishing effect.

The fire extinguishing method in this application will be described in detail below with specific embodiments.

1) Preparation of fire bombs

Predetermine fire-extinguishing plans based on the conditions of most fires. Fire-extinguishing bombs should be prepared at a ratio of 1:2 between dry powder fire-extinguishing bombs and water-based fire-extinguishing bombs (can also be prepared in other ratios according to local multiple fire categories), and loaded into corresponding fire-extinguishing cannon trucks, respectively. The programmable muzzle speed of the corresponding barrels of dry powder fire-extinguishing bombs and water-based fire-extinguishing bombs is available for use. Dry powder bombs are mainly used to suffocate and suppress the fire head and prevent the fire from spreading and expanding; water-based bombs are mainly used to cool and block burning materials.

2)Fire extinguishing bomb loading

Manually control the hydraulic system to unlock the release, insert the fire-extinguishing bombs from the muzzle into the corresponding barrels, and manually control the release to lock the fire-extinguishing bombs. The charging system fills the chamber with a mixture of methane and air to complete the loading process. Set the prescribed release pressure for different fire extinguishing bombs on the programmable console. Complete the ammunition preparation work.

3) Launch preparation

After the artillery carriage reaches the operating position, place the artillery carriage with its axis deflected approximately 30 degrees to the left from the direction of the fire scene, deploy the hoes, and adjust the artillery carriage to the level; the artillery barrel is inflated, and the artillery launch preparation is completed. At the same time, the reconnaissance and observation drone flew to the side of the fire scene, measured the fire scene coordinates, and input the fire scene coordinate information and the artillery vehicle coordinates and direction information into the artillery control system. The artillery control system automatically set the warhead release time for the fire extinguishing bombs. information, adjust the direction angle and height angle of the artillery to aim at the fire field, and the artillery enters the ready-to-fire state.

The on-site commander issues the launch order, observes the fire-fighting effect through reconnaissance and observation drones, and issues correction firing elements. At the same time, determine the order and quantity of firing based on the conditions of the fire scene (scale and type), such as: 2 dry powder bullets first, then 4 water-based bullets (or 5 dry powder bullets first, and 10 water-based bullets later).

4) Fire fighting operations

The artillery control system ignites according to the firing sequence at intervals of 2 seconds. The artillery is fired and ignited. The mixture of air and methane in the barrel deflagrates to generate high pressure to push the projectile into motion. The fuze releases the recoil safety. The moment the projectile exits the muzzle, the fuze tests the speed of the projectile, and corrects the set delay release time based on the speed of the projectile. After the projectile flies 60m away from the muzzle, the crawling safety of the fuze is released; the fuze enters the ready state, the projectile flies above the fire field, the fuze delay release time ends, the ignition signal is output, the warhead air mixture is ignited, and the slow descent and deceleration device is activated. The fire-extinguishing warhead expands and explodes under the action of high-pressure gas, and the fire-extinguishing agent is thrown onto the fire scene to complete the fire-extinguishing operation.

In summary, the present invention has the following advantages:

(1) Use the barrel gun principle and conventional energy power to complete the launch of large-caliber multi-barreled fire-extinguishing projectiles, inheriting the characteristics of multiple rocket launchers, and taking advantage of the barrel gun's high accuracy and large shooting angle;

(2) Using conventional energy-powered multi-variety fire-extinguishing bomb combination fire-extinguishing technology, after firing and ignition, the pressure in the chamber will drop gently, and the timing of the fire-extinguishing bombs being released from the chamber can be controlled through the console to adjust the muzzle speed of the fire-extinguishing bombs, thus achieving different The bullet types (with different bullet weights) have the same landing point function, so that a single platform can be mixed and launched with multiple bullet types (such as solid fire extinguishing agents or water-based fire extinguishing agents, etc.) to achieve efficient combination ("multiple bullet types, same landing point" )Extinguishing;

(3) Using large-capacity and super-caliber intelligent fire-extinguishing bomb technology, the fire-extinguishing bombs are continuously launched to achieve a large-capacity combined delivery of multiple fire-extinguishing agents to the same fire area in a short period of time, which has an overwhelming effect on fire fighting.
