DETAILED DESCRIPTION

[0029] It is easy to understand that, according to the technical scheme of the present application, those skilled in the art can propose a plurality of structure modes and implementation modes which can be replaced with each other without changing the essential spirit of the present application. Therefore, the following detailed description and the accompanying drawings are only exemplary description of the technical scheme of the present application, and should not be regarded as the whole or as the limitation or restriction of the technical scheme of the present application.

[0031] Nowadays, in key scenes such as airport runway, farmland, orchard, power tower, warehouse building, etc., bird activities frequently cause many prominent problems. Bird impact on aircraft in airport area may cause flight delay, equipment damage and even flight accident, which directly threatens aviation safety. In farmland and orchard, a large number of birds peck crops and fruits, which will cause serious yield reduction and affect the economic benefits of farmers. Birds nesting and excreting on power facilities easily cause line short circuit and equipment failure, affecting the stable operation of power system. The warehouse and building roof will be polluted and damaged by bird droppings and nesting, resulting in environmental deterioration and structure loss. The traditional bird driving method is either easily adapted by birds due to single sound wave, or has pollution risk due to chemical bird repellent. Therefore, bird shooting gas gun is needed to generate sound wave and impact airflow by physical method, which can safely scare away birds without harming their lives and environment, and can also avoid bird adaptation, long-term stable driving away of birds in target area, and guarantee the normal order of aviation safety, agricultural production, power operation and facility environment.

[0035] When the device is in use, the bird repeller device body 1 is moved to the designated position, the power is started, the device body is set through the operation panel 16 and the operation button 17, after the adjustment is completed, the bird repeller device body 1 starts to run, the bird repeller compression gas chamber 2 inhales the external gas through the air inlet pipeline 18, the bird repeller compression gas chamber 2 compresses the gas, the high-pressure air after compression is stored in the bird repeller compression gas chamber 2, the servo motor 19 is started, the servo motor 19 drives the sound wave frequency adjusting valve 4 to rotate, selects the appropriate valve core pipeline from the first valve core pipeline 6, the second valve core pipeline 7, the third valve core pipeline 8 and the fourth valve core pipeline 9, and aligns it with the air outlet pipeline 3 and the sound wave release pipeline 5, when driving birds, the bird repeller compression gas chamber 2 discharges compressed gas, when the gas reaches the air outlet pipeline 3, the fixed slope block 20 changes the running track of the gas, adheres to the corner of the air outlet pipeline 3, so that the flow of the gas is more smooth, when the gas reaches the wind baffle 22, the wind baffle 22 rotates around the baffle shaft 21 under the action of pressure, the wind baffle 22 is driven to flow irregularly by swinging under the action of the baffle spring 23, when the gas passes through the sound wave frequency adjusting valve 4, the sound wave changes, when the gas passes through the sound wave release pipeline 5, part of the gas enters the auxiliary air inlet 11, at this time, the pressure in the auxiliary pipeline 10 increases, at this time, the slide block return spring 13 is extruded and shrinks, the movable slide block 14 moves upward, discharges the gas in the auxiliary pipeline 10 through the auxiliary air outlet 12, the arc-shaped groove 15 changes the sound wave, the gas discharged through the auxiliary air outlet 12 mixes with the gas in the sound wave release pipeline 5 to form a composite sound wave, when the bird repeller compression gas chamber 2 stops discharging, the slide block return spring releases the elastic potential energy, drives the movable slide block 14 to reset downward along the axial direction, promotes the residual gas in the auxiliary pipeline 10 to be discharged through the auxiliary air inlet 11, forms another characteristic sound wave in the sound wave release pipeline 5, prolongs the sound wave time.

[0036] The sound wave frequency adjusting valve 4 provided with multiple valve core pipelines can generate different sound waves by switching different valve core pipelines, thereby ensuring the continuous and effective bird repelling performance of the device. Meanwhile, the auxiliary pipeline 10 is provided. When the bird repeller compression gas chamber 2 releases gas, part of the gas enters the auxiliary pipeline 10 through the auxiliary gas inlet port 11. Under the action of pressure, the movable slider 14 moves upward, and the slider return spring 13 is squeezed and contracted. The squeezed gas is discharged through the auxiliary gas outlet port 12 and mixed with the gas in the sound wave release pipeline 5 to form a composite differential sound wave. When the bird repeller compression gas chamber 2 stops working, the movable slider 14 moves downward under the elastic action of the slider return spring 13, which promotes the discharge of the internal gas through the auxiliary gas inlet port 11, forms another characteristic sound wave in the sound wave release pipeline 5, and prolongs the sound wave duration. By configuring the sound wave frequency adjusting valve 4 with multiple valve core pipelines and the auxiliary pipeline 10 with the movable slider 14 and the slider return spring 13, the basic differential sound wave can be generated by switching different valve core pipelines, and the auxiliary gas flow can be mixed with the main gas flow to form a composite differential sound wave by driving the movable slider 14 to move upward and the slider return spring 13 to contract under the pressure of the gas released by the bird repeller compression gas chamber 2.

The three-layer sound wave system greatly improves the bird adaptation difficulty and fundamentally solves the problem of bird repelling effect decay. Meanwhile, the modular design of the multiple valve core pipelines can adapt to different scenes and bird requirements.

[0037] The bird repeller device body 1 can be quickly started by moving to a designated position. When the gas flows, the fixed slope block 20 optimizes the gas flow trajectory, the resistance is reduced by fitting the pipeline corner, and the air resistance baffle 22 swings under the action of gas pressure and spring, which promotes irregular gas flow and ensures smooth gas flow. The sound wave frequency adjusting valve 4 with multiple valve core pipelines can be flexibly switched to generate differential basic sound waves. The auxiliary pipeline 10 drives the movable slider 14 to move upward and the slider return spring 13 to contract under the pressure of the gas, which makes the auxiliary gas flow and the main gas flow blend to form a composite sound wave. After the bird repeller compression gas chamber 2 stops discharging, the spring return 13 drives the slider to move downward to discharge the residual gas, which generates a new characteristic sound wave and prolongs the sound wave duration. The three-layer sound wave system significantly increases the bird adaptation difficulty and fundamentally avoids the bird repelling effect decay. The modular design of the multiple valve core pipelines can accurately adapt to different use scenes and the repelling requirements of various birds, and comprehensively ensures the continuous and efficient bird repelling effect of the device.
