Description

Technical Field

[0001] The utility model relates to the technical field of bird repelling, in particular to an electric high-altitude bird repelling bomb. Background Art

[0002] A bird repelling bomb is a special ammunition for driving away birds, which mainly drives them away by stimulating the senses of birds (such as sound, light, smell, etc.) to prevent birds from damaging airplanes, crops or other important facilities. For existing electric high-altitude bird repelling bombs, generally, an external arc device is used to ignite the lead wire of the bird repelling bomb to prevent the danger of manually igniting the lead wire. These existing high-altitude bird repelling bombs often can only take off first, and then drive away birds through the sound generated by an explosion after taking off. Since the sound is only once, the effect is not particularly good. In big cities or near big cities, some birds are used to the sound, and the frightening effect caused by just hearing an explosion sound is relatively poor. Summary of the Invention

[0003] The purpose of the utility model is to solve the problem that existing bird repelling bombs in the prior art often can only drive away birds through the sound generated by an explosion once, and since the sound is only once, the effect is not particularly good. Thus, an electric high-altitude bird repelling bomb is proposed, which includes an inner shell. A lead wire for ignition is fixedly connected to the upper part of the inner shell. An outer shell is sleeved outside the inner shell. A plurality of limiting protrusions are arranged on the inner side of the outer shell, and the limiting protrusions are fixedly connected to the side wall of the inner shell.

[0004] Preferably: A plurality of chambers are formed between the inner wall of the outer shell, the outer wall of the inner shell and the plurality of limiting protrusions. The bottom of the chamber is completely sealed. A thin plate is arranged on the upper part of the chamber. One side of the thin plate is hermetically connected to the outer shell. An air inlet is arranged between the inner shell and the thin plate. A conical groove is formed on the side wall of the outer shell. The position where the conical groove is formed is on the side of the chamber, and the height where the conical groove is formed is at least greater than half of the height of the outer shell.

[0005] Preferably: The inside of the inner shell includes an explosive layer, a firing pin layer, a mud bottom, a non-porous paper pad, an ignition fuse and a paper piece.

[0006] Beneficial Effects: When the lead wire is ignited, it will first drive the inner shell and the fixedly connected outer shell to take off. When the outer shell takes off, since there is an air inlet between the inner shell and the thin plate, at this time, gas will enter the interior of the chamber. And because a conical groove is formed on one side of the chamber, the airflow entering the air inlet will be vibrated to form many air waves. These air waves are transmitted in the form of sound, and a relatively large sound will be generated during takeoff. The sound will drive away the birds for the first time, and then the secondary explosion sound generated after takeoff will drive away the birds for the second time. Description of the Drawings

[0011] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0012] Refer to Figures 1 to 3 , the electric high-altitude bird repellent bomb, including an inner shell 1, the upper part of the inner shell 1 is fixedly connected and communicated with a lead wire 101 for ignition, an outer shell 2 is placed and sleeved outside the inner shell 1, and a plurality of limiting protrusions 201 are arranged on the inner side of the outer shell 2, and the limiting protrusions 201 are fixedly connected to the side wall of the inner shell 1.

[0013] Preferably, a plurality of chambers 203 are formed between the inner wall of the outer casing 2, the outer wall of the inner casing 1, and the plurality of limiting protrusions 201. The bottom of the chamber 203 is completely sealed. A thin plate 202 is provided at the upper part of the chamber 203. One side of the thin plate 202 is sealingly connected to the outer casing 2. An air inlet 205 is provided between the inner casing 1 and the thin plate 202. A conical groove 204 is formed on the side wall of the outer casing 2. The position where the conical groove 204 is formed is on the side where the chamber 203 is located, and the height at which the conical groove 204 is formed is at least greater than half of the height of the outer casing 2. When the lead wire 101 is ignited, the explosive layer in the inner casing 1 will be detonated, thereby driving the inner casing 1 and the outer casing 2 fixedly connected to the inner casing 1 to lift off. When the outer casing 2 lifts off, due to the air inlet 205 provided between the inner casing 1 and the thin plate 202, at this time, gas will enter the interior of the chamber 203. Also, because a conical groove 204 is formed on one side of the chamber 203, when the inner casing 1 and the outer casing 2 lift off, a whistle principle will be formed inside the chamber 203. When air enters the air inlet 205, the air flow passes through the chamber 203 and generates a series of vibrations on the inner wall of the chamber 203. This kind of vibration is caused by the frictional force between the air flow and the inner wall of the chamber 203. When the air flow passes through the chamber 203, it is hindered by the frictional force between the air column in the chamber 203 and the inner wall of the chamber 203, resulting in the vibration of the air flow and forming many air waves. These air waves are propagated in the form of sound, which will cause a relatively large sound in the air. The sound will drive away the birds for the first time, and then the secondary explosion sound generated after lifting off will drive away the birds for the second time.

[0014] Preferably, the interior of the inner casing 1 includes an explosive layer, a firing pin layer, a mud bottom, a non-porous paper sheet, a fuse, and a paper piece.

[0015] Working principle: During use, the lead wire 101 is ignited by an arc generator. When the lead wire 101 is ignited, the explosive layer in the inner casing 1 will be detonated, thereby driving the inner casing 1 and the outer casing 2 fixedly connected to the inner casing 1 to lift off. When the outer casing 2 lifts off, due to the air inlet 205 provided between the inner casing 1 and the thin plate 202, at this time, gas will enter the interior of the chamber 203. Also, because a conical groove 204 is formed on one side of the chamber 203, when the inner casing 1 and the outer casing 2 lift off, a whistle principle will be formed inside the chamber 203. When air enters the air inlet 205, the air flow passes through the chamber 203 and generates a series of vibrations on the inner wall of the chamber 203. This kind of vibration is caused by the frictional force between the air flow and the inner wall of the chamber 203. When the air flow passes through the chamber 203, it is hindered by the frictional force between the air column in the chamber 203 and the inner wall of the chamber 203, resulting in the vibration of the air flow and forming many air waves. These air waves are propagated in the form of sound, which will cause a relatively large sound in the air. The sound will drive away the birds for the first time, and then the secondary explosion sound generated after lifting off will drive away the birds for the second time.

[0016] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
