[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4This utility model provides a technical solution: a dual-mode UAV countermeasure device, comprising: a bottom shell 1, a connector 2 installed inside the bottom shell 1, a detonation network plate 3 installed inside the bottom shell 1, a panel 4 installed inside the detonation network plate 3, a pre-formed groove 401 and a pre-formed groove 402 on the surface of the panel 4, a charge slot 5 equidistantly formed on the bottom circumference of the inner wall of the detonation network plate 3, a charge slot 6 equidistantly formed on the bottom circumference of the inner wall of the detonation network plate 3, and a flying net 10 at the bottom of the detonation network plate 3.

[0024] Specifically: When in use, the device loads explosives into the explosive charging slots 5 and 6 inside the detonation network plate 3. When the device receives a countermeasure signal, it energizes the explosives in the explosive charging slots 5 and 6 through the connector 2 installed inside the bottom shell 1, causing the explosives to transfer detonation energy. This causes the panel 4 installed inside the detonation network plate 3 to open, forming high-speed fragments that fly in a directional manner. As the fragments are formed, they crack through the pre-formed slots 401 and 402 on the surface of the panel 4, causing the fragments to scatter along a preset path, forming directional damage elements to counter the UAV. The flying net 10 set at the bottom of the detonation network plate 3 captures the UAV, enabling the device to achieve a dual-mode UAV countermeasure effect of superimposed attack and capture, making the device more complete.

[0025] In one embodiment, the shape of prefabricated groove 401 is a circular groove, and the shape of prefabricated groove 402 is a linear groove.

[0026] Specifically: By using a circular groove 401 and a linear groove 402, the panel 4 can be better scattered when broken, thus better countering the drone and making the device more complete.

[0027] In one embodiment, the inner wall of the charging tank 5 is provided with a charging hole 501, the inner wall of the charging tank 5 is provided with a charging hole 502, and the surface of the charging tank 5 is provided with a charging port 503.

[0028] Specifically: the charging holes 501 and 502 on the surface of the charging tank 5 allow the device to charge the drug through these holes. The charging port 503 on the surface of the charging tank 5 allows the drug charged through the charging holes 501 and 502 to enter the interior of the charging tank 5 where the charging holes 501 and 502 are not located, thus improving the charging effect and making the device more complete.

[0029] In one embodiment, the shape of the charge slot 2 6 is a linear slot, and a charge hole 3 601 is provided in the middle position of the charge slot 2 6.

[0030] Specifically: By using the loading hole 3 601 opened in the middle of the loading slot 2 6, the loading can be made more convenient and the device is more perfect.

[0031] In one embodiment, mass blocks 7 are installed at equal intervals around the surface of the detonation network plate 3, and mounting blocks 8 are fixedly installed at the bottom of the mass blocks 7. The mass blocks 7 form an angle with the normal direction of the detonation network plate 3. A connecting line 9 is installed at the other end of the mounting block 8 by bolts, and the other end of the connecting line 9 is fixedly installed on the surface of the flying net 10.

[0032] Specifically: Mass blocks 7 are evenly installed on the outer circumference of the detonation network plate 3. The mounting block 8, which is fixedly installed at the bottom of mass blocks 7, is installed on one end of the connecting line 9 by bolts. The other end of the connecting line 9 is fixedly installed on the surface of the flying net 10. When the detonation signal continues to be transmitted to the outer circumference of the detonation network plate 3, the mass blocks 7 can quickly pull the flying net 10 out to capture the drone affected by the fragments. This enables the device to achieve a dual countermeasure effect of attack and capture, making the device more complete.

[0033] Working principle: Charges are loaded into the inner wall of charge tank 5 through charging holes 501 and 502. The charge port 503 on the surface of charge tank 5 allows the charge to enter the interior of charge tank 5 without charging holes 501 and 502, improving the loading effect. The charging hole 601 in the middle of charge tank 6 allows the charge to be loaded into the interior of charge tank 6 during loading. Then, the connecting piece 2 installed inside the bottom shell 1 is energized to activate the charge in charge tanks 5 and 6, transferring detonation energy and activating the detonation network plate. 3. The internally installed panel 4 is opened, and the pre-formed grooves 401 and 402 on the surface of the panel 4 form high-speed fragments that are directionally dispersed, forming directional damage elements to counter the drone. This allows the device to strike the drone. Mass blocks 7 are evenly installed on the outer circumference of the detonation network plate 3. The mounting block 8, which is fixedly installed at the bottom of the mass blocks 7, is bolted to one end of the connecting line 9. The other end of the connecting line 9 is fixedly installed on the surface of the flying net 10. When the detonation signal continues to be transmitted to the outer circumference of the detonation network plate 3, the mass blocks 7 can quickly pull the flying net 10 out to capture the drone affected by the fragments. This allows the device to achieve a dual countermeasure effect of striking and capturing, making the device more complete.

[0034] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
