DETAILED DESCRIPTION OF THE EMBODIMENTS:

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0017] Such as Figures 1-4As shown in the figure, a bird repellent air cannon includes a box body 1, an air pump 2, a high-pressure inflator 3, a sound generating throat tube 4, a sound amplifying tube 5 and a partition 6. Among them, the air pump 2 and the high-pressure inflator 3 are both existing devices. The air pump 2 uses a DC-12V DC air compressor, and the high-pressure inflator 3 uses a Xiangda 10-gallon high-pressure inflator 3. The specific structure will not be elaborated here. The box body 1 is used to provide installation positions for each device. Universal wheels 8 are installed at the four corners of the bottom of the box body 1 through legs 7, which facilitates the movement of the entire box body 1.

[0018] The high-pressure inflator 3 is installed in the box body 1 and is used as an air storage cylinder. Horizontally arranged support plates 15 are welded and fixed on each leg 7 below the box body 1. The air pump 2 is fixed on the support plate 15. The outlet of the air pump 2 is connected to the inlet of the high-pressure inflator 3 through a pipeline. The high-pressure inflator 3 is inflated by the air pump 2. A backup battery 9 and a storage battery 10 are also fixed on the support plate 15. A solar panel is installed on one side outside the box body 1. When there is sufficient sunlight, the solar panel can convert solar energy into electrical energy and store it in the storage battery 10 for use by the air pump 2. The air pump 2 can be powered by the solar panel, the backup battery 9 or 220V mains power. The sound amplifying tube 5 is fixedly penetrated and installed on the side wall of the box body 1 and has the function of amplifying sound. The outlet of the high-pressure inflator 3 is connected to the small-diameter end of the sound amplifying tube 5 through the sound generating throat tube 4. The length of the sound generating throat tube 4 is 21 cm. The large-diameter end of the sound amplifying tube 5 passes through the side wall of the box body 1 and is placed outside the box body 1. A plurality of partitions 6 are fixedly spaced in the sound generating throat tube 4 near the small-diameter end of the sound amplifying tube 5. The plate surface of each partition 6 is arranged perpendicular to the axis direction of the sound generating throat tube 4. Through holes 6.1 are penetrated and opened on each partition 6. The through holes 6.1 of each partition 6 are arranged from large to small along the gas flow direction, and the through holes 6.1 of each partition 6 are staggered. When compressed air enters the sound generating throat tube 4, in a short time, the compressed air quickly flows out from the gradually shrinking through holes 6.1, which can expand the vibration effect and generate an air cannon. And because the through holes 6.1 are staggered, the generated air cannon has a vortex ring, can transmit waves over a longer distance and has a longer duration, which can have a greater impact on bird flight.

[0019] A pressure sensor 11 is provided on the high-pressure inflator 3 to monitor the pressure value inside the high-pressure inflator 3 in real time. The pressure sensor 11 is electrically connected to the input end of the controller 12, and the output end of the controller 12 is electrically connected to the power switch of the air pump 2. When the pressure sensor 11 detects that the gas pressure value inside the high-pressure inflator 3 exceeds the maximum set value, it transmits a signal to the controller 12, and the controller 12 controls the power switch of the air pump 2 to close, so that the air pump 2 stops inflating; when the pressure sensor 11 detects that the gas pressure value inside the high-pressure inflator 3 is lower than the minimum set value, it transmits a signal to the controller 12, and the controller 12 controls the power switch of the air pump 2 to open, so that the air pump 2 starts inflating;

[0020] A quick exhaust valve 13 is provided at the outlet of the high-pressure inflator 3. By opening the quick exhaust valve 13, the compressed air inside the high-pressure inflator 3 is instantaneously released to generate an air cannon for bird repelling. A timer 14 is installed on the box body 1. The timer 14 is connected to the input end of the controller 12, and the output end of the controller 12 is connected to the quick exhaust valve 13. The timer 14 is controlled by the remote control switch of the mobile phone, and the working frequency of the quick exhaust valve 13 can be set through the mobile phone.

[0021] Working process: The high-pressure inflator 3 is inflated by the air pump 2. The air pump can fill the gas pressure inside the high-pressure inflator 3 to 7 Kpa within 1 minute and 30 seconds. When the pressure sensor 11 detects that the gas pressure inside the high-pressure inflator 3 exceeds 7 Kpa, it transmits a signal to the controller 12, and the controller 12 controls the power switch of the air pump 2 to close, so that the air pump 2 stops inflating; the working frequency of the quick exhaust valve 13 is set through the mobile phone, and it is set to generate a blasting sound once every 5 - 10 minutes. When the quick exhaust valve 13 is opened, the compressed air enters the sound generating throat 4. In a short time, the compressed air rapidly flows out from each through hole 6.1 that gradually narrows, which can expand the vibration effect to generate an air cannon. And because the through holes 6.1 are arranged staggeredly, the generated air cannon has a vortex ring, can transmit over a longer distance, and has a longer duration, which can have a greater impact on bird flight.

[0022] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
