Sound amplifying tube for generating valley echo effect of repelling bird impact waves and control method

Abstract

The invention belongs to the technical field of bird repelling equipment, and discloses a sound amplifying tube for generating valley echo effect of repelling bird impact waves and a control method. The sound amplifying tube comprises a blasting chamber, wherein a blasting gas inlet is formed in the right end of a blasting chamber, a blasting gas inlet joint is welded in the blasting gas inlet, acenter shaft is welded at the left end of the blasting gas inlet joint; and a cross-shaped fixing support is welded to the left end of the center shaft and fixed to the left end of the inner side of the blasting chamber in a welded mode; and a plurality of equidistantly arranged triangular airflow diversion frames are welded in the middle of the central shaft, and the plurality of triangular airflow diversion frames have the same angle difference in sequence from left to right. The sound amplifying tube is prevented from being influenced by the external environment, good explosion sounds can be generated, the explosion sounds are louder than that of a traditional gas gun, the energy is greater, a spiral structure is formed by the plurality of triangular airflow diversion frames, three strands of impact waves with the spiral rotating direction are formed through dredging of the triangular airflow dredging frames, and the sounds are transmitted farther and have the feature of valley echoeffect.

Description

technical field [0001] The invention belongs to the technical field of bird repelling equipment, and particularly relates to a loudspeaker tube and a control method for generating a valley echo effect for bird repelling shock waves. Background technique [0002] At present: Gas cannons are the most used for bird protection in the airport flight area. At present, the barrel of the gas gun is simply divided into an explosion chamber and an explosion gas discharge pipe. The explosion gas discharge pipe is hollow. This kind of barrel has a simple structure and is easily affected by the external environment (such as wind, air pressure, humidity), The sound produced (no more than 135db) is not too large and not far enough to shock the bird. [0003] Through the above analysis, the existing problems and defects in the prior art are: the existing gas cannons for bird repelling are simple in structure, easily affected by the external environment, the generated sound (no more than 13...
