It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 to 3, a combined bird repelling device includes: a shock wave generator 1 generating a high sound pressure and high directivity shock wave cyclone; the bird repellent output device 2 is connected with the shock wave generator 1 and is used for outputting bird repellent; wherein the bird repellent output device 2 outputs the bird repellent to the cyclone of the shock wave generated by the shock wave generator 1.
The high-directivity shock wave cyclone is linearly transmitted, and has the characteristic of rotation, so that when the high-directivity shock wave cyclone is transmitted in the air, the energy loss is small, the transmission distance is long, the bird repelling range can be increased, the bird repelling agent is input into the shock wave cyclone, is smashed and distributed more uniformly, and is carried by the shock wave cyclone and then uniformly distributed in a pointing area; has the functions of quickly responding to bird repelling and continuously repelling birds in a pointed area, and ensures the uniform distribution of bird repelling agents.
Further, the shock wave generator 1 includes: a gas-fired device 11; the gun barrel 12 is connected with the gas device 11 and is internally provided with the rectifying device 3; the rectifying device 3 adjusts the gas before and after the explosion to generate high-loudness sonic cyclone.
The sound wave is restrained by adopting the mode of the gun barrel 12, so that the sound wave with high directivity is formed, and the propagation distance of the sound wave is increased. The gas device 11 adopts gas input equipment to input gas into the gun barrel 12 and ignite, and then deflagration occurs to generate impact sound waves, wherein the gas input equipment is the prior art, and the effect is only to input gas. The fuel gas of the combined bird repelling device adopts carbon-containing gas, and mainly comprises the following components: one or more of ethylene, acetylene, ethane, propane, coal gas, etc., and further preferably ethylene or coal gas, because ethylene gas is the most safe and coal gas is the most available and the cost is the lowest. The rectifying device 3 rectifies sound waves generated by gas explosion to form shock wave cyclone with sound pressure of more than 200dB and extremely high loudness. The barrel can be movable mounting and realize the free rotation every single move on the support, and concrete structure can be a bearing of shelf location, a dwang of this bearing inscription, and the breach is seted up to the dwang upper end, connecting block of barrel 12 below fixed connection, and the connecting block passes through the bolt to be settled in the breach of dwang, and the dwang can be rotatory by the relative support, but the every single move of barrel 12 relative dwang is realized to barrel 12 relative dwang.

The gas device 11 inputs gas into the gas inlet mechanism, the gas inlet mechanism guides the gas flow, disordered gas regularly flows in the gun barrel 12 after passing through the gas inlet mechanism, and the gas device 11 ignites the regularly flowing gas to form explosion, which is an explosion point 33. The blasting sonic flow passes through the rectifying mechanism 32 to form a rotating sonic flow which is emitted from the nozzle of the gun barrel 12. The air inlet mechanism occupies a certain volume in the gun barrel 12, so that the volume of the gas which can be accommodated and passed is smaller than that of the gas which can be accommodated at the explosion point 33, the gas is reserved when more space exists at the explosion point 33 after passing through the air inlet mechanism and then is injected into air by the gas device 11 to be ignited, and the gas can be concentrated on the explosion point 33 as much as possible by setting the volume of the explosion point 33 to be larger than that of the gas which can be passed through the air inlet mechanism, so that the loudness of sound is improved, and the bird repelling effect is further increased. In addition, after the explosion point 33 explodes, the sound wave airflow passes through the air inlet mechanism to return and collide with the gas device 11, forms an echo, and then is transmitted to the rectifying mechanism 32 to be superposed with the sound wave at the rectifying mechanism 32 for transmission. The sound wave is rectified by the rectifying mechanism 32 to form a sound wave cyclone. The gas passing through the gas inlet means can be equally distributed to the explosion point 33 in the barrel 12 effectively.

In addition, the spiral staggered comb tooth structure 35 can reduce the problem that residual waste gas flows back to the outlet of the gas device 11 after gas explosion to a certain extent, and influences the next explosion. In addition, set up different widths with guide rod 351 on the broach structure 35, the sound wave that detonation produced in explosion point 33 department strikes on different guide rod 351, and the sound wave stack that produces in echo and the fairing 32 of production forms the sound wave of higher frequency, and the effect strengthens greatly. The comb-shaped structure 35 is adjustably mounted on the mounting rod 34 in a plurality of ways, for example, a through hole is formed in the guide rod 351 of the comb-shaped structure 35 along the length direction of the guide rod, the guide rod is screwed into the through hole through a bolt, and then the guide rod abuts against the mounting rod 34 to achieve locking, and the comb-shaped structure 35 can be adjusted to axially slide or rotate along the mounting rod 34 after the bolt is screwed out.
Further, the pitch of the two comb tooth structures 35 increases in order from the gas combustion device 11.
The comb tooth structure 35 not only has the function of dredging the fuel gas, but also has the function of reducing the volume of the fuel gas at the position, so that the fuel gas is easy to remain at the subsequent explosion point 33 with larger volume; moreover, broach structure 35 still possesses the effect of even gas, distribute uneven gas behind the helical space that broach structure 35's guide rod 351 formed, along with the interval increase between broach structure 35, subsequent broach structure 35 can't form perfect helical space with preceding broach structure 35 (the guide rod 351 of preorder broach structure 35 has the overlap portion in the axial of settling pole 34 promptly, it is subsequent), the gas is smashed by subsequent broach structure 35's guide rod 351 this moment, be equivalent to the reef of the protrusion surface of water in the rivers, make the gas degree of consistency improve.
