Low-cost practical fire extinguishing bomb power device ignition system

Abstract

The invention discloses a low-cost practical fire extinguishing bomb power device ignition system. The system comprises a combustion chamber, a spray pipe and an igniter, wherein the combustion chamber and the spray pipe are detachably and fixedly connected, the igniter is arranged between the combustion chamber and the interior of the spray pipe, a spray pipe plug cover is detachably fixed on theigniter, the outer ring of the spray pipe plug cover is detachably connected to the connecting end between the combustion chamber and the spray pipe, the spray pipe plug cover can cover the space between the igniter and the inner wall of the spray pipe, a ring of annular shear ring is also prefabricated on the spray pipe plug cover, and the fracture force of the annular shear ring is smaller thanthe injection force of gas flow. The separation mode of the igniter provided by the invention abandons the design of connecting an igniting system by a conventional detachable plug, eliminates the connection mode that a conventional igniting system needs to be unlocked and separated, saves the complicated mechanical action that the plug falls off, is simple and practical in connection structure,and can greatly reduce the system cost.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle fire extinguishing, and in particular relates to an ignition system of a low-cost practical fire extinguishing bomb power device. Background technique [0002] In recent years, with the frequent occurrence of urban high-rise fires and forest fires, the difficulty of fire fighting and rescue in high-rise buildings has become a recognized worldwide problem. The traditional fire-fighting methods, especially in the face of high-rise fires, have relatively large limitations and low efficiency. Therefore, countries have developed new fire extinguishing methods in succession. With the advancement of drones and artificial intelligence systems, the huge advantages of drone fire extinguishing systems have gradually emerged. In the case of poor roads and traffic interruptions, take the drone to the scene of the disaster accident. The conditions for using the drone to take off are simple and t...

AI Technical Summary

Problems solved by technology

[0003] Due to competition considerations, low price is a prerequisite for developing a UAV fire extinguishing system. The rocket engine of the fire extinguishing bomb accounts for the bulk of the overall cost of the fire extinguishing bomb, and the conventional ignition system of the rocket engine needs to be unlocked and disconnected. Costs tend to be higher and the disengagement process more complex
