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] like Figures 1 to 6 As shown, this utility model provides a counter-drone device that facilitates the replacement of laser interception equipment. It includes a connecting plate 1 for mounting on the bottom of the drone. A fixing frame 2 is fixedly connected to the bottom of the connecting plate 1. A fixing groove is formed at the bottom of the fixing frame 2. A stepper motor 3 is fixedly connected inside the fixing groove. A rotating disk 4 is fixedly connected to the output end of the stepper motor 3. A hinge frame 5 is fixedly connected to the bottom of the rotating disk 4. A mounting frame 6 is rotatably connected inside the hinge frame 5. A mounting opening 7 is formed on the outer side of the mounting frame 6. A laser interception device body 8 is housed inside the mounting opening 7. A mounting interface 9 is formed on the rear side of the mounting frame 6, and the mounting interface 9 engages with the interface end of the laser interception device body 8. Positioning grooves 10 are symmetrically formed on both sides of the outer shell of the laser interception device body 8. Limiting cavities 11 are symmetrically formed on both sides of the mounting frame 6. A positioning bolt 12 is threadedly connected to the outer side of the limiting cavity 11, and the positioning bolt 12 penetrates the limiting cavity 11 and engages with the positioning groove 10. A limiting ring 13 is sleeved on the surface of the positioning bolt 12, and the limiting ring 13 cooperates with the limiting cavity 11.

[0024] refer to Figure 2 and Figure 4 The top of the mounting frame 6 is provided with a convex groove 14. A slider 15 is slidably connected inside the groove 14, and the slider 15 fits into the groove 14. The bottom of the rotating disk 4 is hinged to an electric telescopic rod 16 through a hinge, and the output end of the electric telescopic rod 16 is hinged to the slider 15.

[0025] As a technical optimization of this utility model, by setting up the slide groove 14, the slider 15 and the electric telescopic rod 16, when the electric telescopic rod 16 extends or retracts, it can push the slider 15 to slide in the slide groove 14, thereby driving the mounting frame 6 to rotate around the hinge frame 5, realizing the angle adjustment of the main body 8 of the laser interception equipment in the vertical direction, further improving the aiming accuracy and strike effect of the target UAV.

[0026] refer to Figure 4 and Figure 6The mounting frame 6 has symmetrically provided U-shaped fastening grooves 17 on both sides, and the bottom of the fastening grooves 17 is connected to the limiting cavity 11. The inside of the fastening grooves 17 is slidably connected to the extrusion strip 18. The bottom of the extrusion strip 18 is fixedly connected to the half tooth ring 19. The surface of the limiting ring 13 is fixedly connected to several annularly evenly arranged teeth 20, and the teeth 20 are engaged with the half tooth ring 19. The top of the extrusion strip 18 is symmetrically fixedly connected to the compression spring 21, and the other end of the compression spring 21 is fixedly connected to the fastening groove 17.

[0027] As a technical optimization of this utility model, the fastening groove 17, the extrusion strip 18, the half-tooth ring 19, the teeth 20 and the downward pressure spring 21 can form a fastening and limiting mechanism for the positioning bolt 12. When the positioning bolt 12 is tightened, the teeth 20 on the limiting ring 13 engage with the half-tooth ring 19. Through the action of the extrusion strip 18 and the downward pressure spring 21, the fixation of the positioning bolt 12 can be further enhanced to prevent it from loosening, thereby ensuring the installation stability of the laser interception device body 8.

[0028] refer to Figure 4 and Figure 6 The mounting frame 6 has symmetrically opened actuation ports 22 on both sides, and the actuation ports 22 are connected to the fastening groove 17. The outer side of the extrusion strip 18 is fixedly connected to the actuation block 23, and the actuation block 23 is slidably connected to the actuation port 22.

[0029] As a technical optimization of this utility model, the setting of the toggle port 22 and the toggle block 23 makes it convenient for the operator to slide the toggle block 23 in the toggle port 22 to push the squeezing strip 18, thereby releasing the engagement between the half tooth ring 19 and the tooth 20, facilitating the operation of the positioning bolt 12, and improving the convenience of replacing the main body 8 of the laser interception device.

[0030] refer to Figure 4 The bottom of the fixed frame 2 is provided with a T-shaped balance groove, and the top of the rotating disk 4 is fixedly connected with a balance ring 24, which is rotatably connected to the balance groove.

[0031] As a technical optimization of this utility model, the setting of the balance groove and the balance ring 24 can ensure the stability and balance of the rotating disk 4 during the rotation process, reduce the shaking and vibration caused by the rotation, which is conducive to improving the aiming accuracy and strike effect of the laser interception equipment, and can also reduce the impact on the flight attitude of the UAV.

[0032] refer to Figure 3 and Figure 5 The top of the inner wall of the installation port 7 is symmetrically provided with magnetic grooves 25, and the top of the main body 8 of the laser interception device is symmetrically fixedly connected with magnetic strips 26, and the magnetic strips 26 are magnetically connected to the magnetic grooves 25.

[0033] As a technical optimization of this utility model, by setting up the magnetic groove 25 and the magnetic strip 26, the main body 8 of the laser interception device can be initially positioned and fixed by magnetic attraction when it is installed, which facilitates the subsequent installation operation and also enhances the stability of the main body of the device within the installation frame 6.

[0034] The working principle and usage process of this utility model are as follows: When using this counter-drone device, firstly, the main body 8 of the laser interception device is placed into the mounting frame 6 through the mounting port 7, so that the interface end of the main body 8 of the laser interception device is engaged with the mounting interface 9 on the rear side of the mounting frame 6. Then, the magnetic strip 26 on the top of the main body 8 of the laser interception device is magnetically connected to the magnetic groove 25 on the top of the inner wall of the mounting port 7, achieving initial positioning and fixation. Then, first slide the actuating block 23 upward, driving the compression strip 18 and the half-tooth ring 19 to slide upward, and compressing the downward spring 21. Then, rotate for positioning. The positioning bolt 12 is tightened so that its interior passes through the limiting cavity 11 and engages with the positioning grooves 10 on both sides of the outer shell of the laser interception device body 8. Simultaneously, the limiting ring 13 works in conjunction with the limiting cavity 11 to firmly fix the laser interception device body 8 within the mounting frame 6. After the positioning bolt 12 is tightened, the actuating block 23 is released, causing the compression strip 18, under the action of the downward spring 21, to drive the semi-toothed ring 19 to engage with the teeth 20 of the limiting ring 13. This fixes the limiting ring 13, further strengthening the fixation of the positioning bolt 12 and preventing it from loosening. When it is necessary to adjust the laser interception device body... When disassembling and maintaining the main body 8, the above operations can be reversed. Take out the old laser interception device main body 8 from the installation port 7, and then install the new laser interception device main body 8 into the installation frame 6 according to the installation steps. When the laser interception device main body 8 needs to be adjusted horizontally during the use of the UAV, start the stepper motor 3. The output end of the stepper motor 3 drives the rotating disk 4 to rotate. The rotating disk 4 drives the installation frame 6 and the laser interception device main body 8 to rotate horizontally together through the hinge frame 5, thereby adjusting the horizontal angle of the laser interception device. At this time, the balance ring 24 at the top of the rotating disk 4 is rotatably connected to the balance groove at the bottom of the fixed frame 2, thereby ensuring the stability and balance of the rotating disk 4 during rotation to align with the target UAV. When adjusting the laser interception device main body 8 vertically, start the electric telescopic rod 16. When the electric telescopic rod 16 extends and retracts, it pushes the slider 15 to slide in the slide groove 14 at the top of the installation frame 6, thereby driving the installation frame 6 to rotate around the hinge frame 5, realizing the vertical angle adjustment of the laser interception device main body 8 and improving the aiming accuracy of the target UAV.
