A gas cannon that uses recoil to change decibels

Abstract

A gas cannon that uses recoil to change decibels includes a mounting seat, four corners of the bottom of the mounting seat are fixedly connected with support legs, and a high-voltage ignition device is fixedly connected to the left side of the top of the mounting seat. The gas cannon, which uses recoil to change the decibel, is used in conjunction with the outer barrel and the inner barrel. Each time the gas cannon is used, it will generate a large recoil, which will cause the high-pressure ignition device to shift to the left. At this time The high-pressure ignition device will drive the inner gun barrel to move to the left through the connecting rod, so that the inner gun barrel rotates so that the high-pressure ignition device corresponds to the muzzle of another diameter. The same, so the sounds emitted by the adjacent muzzles are different, and the rotation is one cycle. There are four kinds of muzzles that can emit different decibels, so as to achieve the effect of changing the decibel of the explosion sound, reducing the adaptability of the bird and improving the driving force. bird effect.

Description

technical field [0001] The invention relates to the technical field of gas guns, in particular to a gas gun that uses recoil force to change decibels. Background technique [0002] The gas cannon is one of the bird repelling devices at the airport. During the working process, the gas cannon ignites the gas through the high-pressure ignition device. After the gas is burned under high pressure, it will generate a strong air flow. When the strong air flow passes through the gun tube, it will make an explosion sound. Finally, the explosion sound is used to drive the birds away to ensure the safety of the plane. However, because the current gas cannon can only emit the same decibel explosion sound, and the decibel range of the sparrow can hear is between 10-150 decibels, and the egret can hear it The decibel range of the sound is between 0-160 decibels. After a long time, the bird will gradually get used to the same decibel explosion sound, and the bird will no longer be afraid o...

[0002] The gas cannon is one of the bird repelling devices at the airport. During the working process, the gas cannon ignites the gas through the high-pressure ignition device. After the gas is burned under high pressure, it will generate a strong air flow. When the strong air flow passes through the gun tube, it will make an explosion sound. Finally, the explosion sound is used to drive the birds away to ensure the safety of the plane. However, because the current gas cannon can only emit the same decibel explosion sound, and the decibel range of the sparrow can hear is between 10-150 decibels, and the egret can hear it The decibel range of the sound is between 0-160 decibels. After a long time, the bird will gradually get used to the same decibel explosion sound, and the bird will no longer be afraid of the same decibel explosion sound, resulting in a reduced repelling effect. Therefore, we propose a method using The recoil to change the decibel gas cannon to solve the above problems
