The present application relates to the technical field of aerial bomb fuze, and discloses a novel aerial bomb fuze clockwork mechanism with rotation speed control, which comprises a gear train, a rotor prime mover body, a safety device, a lower check ring and a rotor, characterized in that the safety device is fixed on the shaft of the gear train by the lower check ring, the safety device is provided with gear teeth and is engaged with the output wheel in the gear train, and the safety device is driven to rotate by the output wheel; the constant speed governor is located between the gear train and the toothed disc, the toothed disc is fixed with the bushing through riveting and is fixed on the central shaft by the upper check ring; the other end of the anemometer shaft is connected with the rotor seat through screw threads, the rotor seat can rotate relative to the time mechanism shell and drives the anemometer to rotate; and the rotor is fixed on the rotor seat. The present application can improve the timing accuracy, prevent the safety from being released too early, better protect the safety of the airplane and the pilot, has certain overload resistance, and when the overload reaches 20G, all the internal parts can remain stable and will not be damaged.

The present application relates to the technical field of aerial bomb fuze, especially to a mechanical time aerial bomb fuze with universal ignition function. The aerial bomb fuze currently used has problems of large timing error, insufficient ignition reliability and safety. The present application designs an anemometer and an isokinetic speed regulator, and through the regulation and control of the two, effectively increases the timing accuracy and safety. Considering that the M904 fuze adopts an impact ignition mechanism, if the angle of the aerial bomb when landing is not within the range of impact ignition, normal ignition will not be achieved. To overcome this limitation, the present application adopts a universal inertia ignition mechanism, improving the ignition reliability.

The application discloses a ground-air integrated multifunctional fire extinguishing system and belongs to the technical field of fire-fighting equipment. The system comprises a ground vehicle combat unit, an aerial bomb-throwing unit and a high-rise building fixed water spraying unit. The ground vehicle is composed of an ice cannon launching vehicle and a water supply supply vehicle, the ice cannon vehicle adopts a six-legged walking mechanism and a multi-tube launching device, can launch high-density ice bombs or other fire extinguishing media, and is provided with an independent generator and a quick power supply interface, and the two vehicles are backup for each other; the aerial unmanned aerial vehicle or fixed-wing aircraft is hung with a throwable ice bomb cabin to realize high-altitude accurate attack; and the high-rise building is internally provided with a multi-section relay type independent water spraying system. The application effectively solves the fire extinguishing problems of complex fire scenes such as mountains, high-rise buildings and oil and chemical plants through ground-air three-dimensional cooperation, double effects of ice bomb cooling and suffocation, safe redundant power supply and all-terrain adaptability, and has the advantages of high fire extinguishing efficiency, strong reliability and wide application range.
