Spring type multi-functional air cannon free of air source

Abstract

The invention relates to a spring type multi-functional air cannon free of an air source. The air cannon is characterized in that the elastic potential performance of a spring is collected by the aidof a mechanism and becomes the kinetic energy of the air cannon after being shot, the bird repelling effect is relatively ideal, and accidents that birds strike airplanes can be effectively preventedand reduced; during emergency rescue and disaster relief, life rafts, life buoys, life lines and anchor hooks can be thrown, and cables can be thrown on warships; during dealing with pirates, water can be sprayed by the aid of water cannons, and stones and bricks can be thrown; during fire extinguishment for high-rises, fire extinguishing bombs can be shot, and bricks and stones can be thrown to break doors and windows; during anti-terrorism actions, extra-large catching nets, bombs, tear bombs and smoke bombs can be shot; and during meeting with foreign guests, the air cannon can be used as asalute.

Description

technical field [0001] The present invention relates to an air cannon, in particular to a spring-type multifunctional air cannon without an air source. Pirate's weapon. Background technique [0002] There are often bird activities in the air above the airport. The stranded and flying of these birds seriously affect the normal take-off and landing of the aircraft, and even bird collision incidents occur. At present, in order to prevent the occurrence of the above-mentioned incidents, two methods are generally adopted, one is the silent repelling method, such as setting scarecrows around the airport, hanging dead birds and sticky bird nets, etc.; the other is the sound repelling method, such as bird repelling guns , A certain amount of liquefied petroleum gas and acetylene are mixed with air and oxygen into the barrel for temporary storage, and then ignited by a high-pressure spark plug, and the pressure is generated in the barrel and sprayed outward to produce sound, so as t...

AI Technical Summary

Problems solved by technology

The weak point of the above multiple methods of driving birds is: the silent driving method can only work on the birds flying at low altitude, and the sound driving method must use fuel, which will cause air pollution after burning, its structure is complicated, and the cost of use is high. It is very unsafe to use, and it is not easy to use bird repellent due to the high temperature generated by gas combustion

During rescue at sea, it is difficult to throw the cable life-saving rope and life-saving equipment to a long distance by hand
