Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the 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 shall fall within the protection scope of the present utility model.
[0025] The present utility model provides as Figures 1 - 5A portable UAV detection, identification and positioning device as shown includes a base 1. A support rod 2 is fixedly connected to the upper end of the base 1. A locking disc 3 is fixedly connected to the upper end of the support rod 2.

The UAV detection, identification and positioning device can stand on the ground through the base 1 and the support rod 2, and adjust the signal capture azimuth through the rotation between the locking disc 3 and the bearing head 4. At the same time, the signal capture elevation can be adjusted through the rotation between the elevation turntable 5 and the elevation head 6. And the UAV detection, identification and positioning device can capture signals through the detection and identification mechanism 7, and can enhance the signal capture ability of the detection and identification mechanism 7 through a plurality of enhanced antennas 8, so that the UAV detection, identification and positioning device can adjust the capture azimuth and capture elevation according to the azimuth and height of the UAV, ensuring stable detection and identification of the UAV and preventing signal loss.
[0026] Preferably, an insertion and extraction card slot 9 is opened inside the center of the rear end of the detection and identification mechanism 7, and the elevation head 6 is inserted into the inside of the insertion and extraction card slot 9. Fixed card slots 10 are opened inside the inner walls at both left and right ends of the insertion and extraction card slot 9. Fixed card heads 11 are clamped inside the two fixed card slots 10. One end of the two fixed card heads 11 away from the fixed card slots 10 is connected to a splitting button 13 through a connecting slide plate 12. And the two fixed card heads 11, the two connecting slide plates 12 and the two splitting buttons 13 are respectively slidably connected to the inside of the front sides at both left and right ends of the elevation head 6. One end of the two fixed card heads 11 and the two splitting buttons 13 close to the fixed card slots 10 protrudes outside the elevation head 6, and the two splitting buttons 13 are both located at the rear side of the detection and identification mechanism 7. A fixed spring 14 is arranged between the two splitting buttons 13 and is elastically connected to the inside of the elevation head 6 through the fixed spring 14. During the installation process of the UAV detection, identification and positioning device, the detection and identification mechanism 7 can be connected to the elevation head 6 through the insertion and extraction card slot 9, and fixed through the clamping between the two fixed card heads 11 slidably connected to the inside of the front sides at both left and right ends of the elevation head 6 and the fixed card slots 10 opened inside the inner walls at both left and right ends of the insertion and extraction card slot 9, so that the detection and identification mechanism 7 can be firmly and stably installed at the front end of the elevation head 6.
[0027] Preferably, after the use of the UAV detection, identification and positioning device, by pressing the splitting button 13 connected to the fixing chuck 11, the fixing chuck 11 can slide into the elevation swivel head 6, and the fixing chuck 11 can be disengaged from the fixing slot 10, thereby releasing the fixation between the elevation swivel head 6 and the detection and identification mechanism 7, enabling the detection and identification mechanism 7 to be smoothly detached from the front end of the elevation swivel head 6, and further making the UAV detection, identification and positioning device more convenient for maintenance and carrying.
[0028] Preferably, locking shafts 15 are slidably connected to the inner sides of the rear ends of the left and right sides of the elevation swivel head 6. A locking spring 16 is arranged between the two locking shafts 15 and is elastically connected to the inside of the elevation swivel head 6 through the locking spring 16. The two locking shafts 15 are respectively clamped in the two elevation swivel seats 5 through locking holes 17, and the two locking holes 17 are respectively opened in the inner sides of the two elevation swivel seats 5 close to the elevation swivel head 6. During the process of adjusting the elevation angle for capturing the UAV detection, identification and positioning device, the elevation swivel head 6 can be connected to the two elevation swivel seats 5 through the locking shafts 15 arranged on the inner sides of the rear ends of the left and right sides, and can rotate between the two elevation swivel seats 5 through the two locking shafts 15 and the two locking holes 17. By forcefully rotating the elevation swivel head 6, the elevation swivel head 6 can adjust the elevation angles of the front-end detection and identification mechanism 7 and the multiple booster antennas 8 through rotation between the two elevation swivel seats 5, thereby adjusting the elevation angle for capturing the UAV detection, identification and positioning device. After the adjustment of the elevation angle for capturing is completed, since the two locking shafts 15 are elastically connected to the elevation swivel head 6 and the inner sides of the two locking holes 17 through the locking spring 16 and can be tightly clamped with the two locking holes 17, the two locking shafts 15 can be locked with the two locking holes 17 through the locking spring 16, thereby locking the elevation swivel head 6 inside the elevation swivel seat 5, ensuring that the angles of the detection and identification mechanism 7 and the multiple booster antennas 8 no longer change, and ensuring that the elevation angle for capturing the UAV detection, identification and positioning device remains stable.
[0029] Preferably, a locking pressure ring 18 is arranged on the outer side between the locking disc 3 and the azimuth rotating head 4, and the outer wall of the lower end of the locking pressure ring 18 is closely attached to the outer side of the upper end wall of the locking disc 3. A plurality of telescopic sliding sleeves 19 are fixedly connected to the outer side of the upper end of the locking pressure ring 18. The plurality of telescopic sliding sleeves 19 are all inserted into the inner part of the outer side of the lower end of the azimuth rotating head 4 through telescopic holes 20, and the plurality of telescopic holes 20 are all opened in the inner part of the outer side of the lower end of the azimuth rotating head 4. A pressing spring 21 is arranged in the upper end part of each of the plurality of telescopic sliding sleeves 19 and is elastically connected to the inside of the telescopic hole 20 through the pressing spring 21. During the process of adjusting the capturing azimuth of the UAV detection, recognition and positioning device, since the locking pressure ring 18 can limit its position with the azimuth rotating head 4 through the plurality of telescopic sliding sleeves 19 and the plurality of telescopic holes 20, the azimuth rotating head 4 can limit its position with the locking disc 3 through the locking pressure ring 18. When the capturing azimuth needs to be adjusted, by rotating the azimuth rotating head 4 forcefully, the azimuth rotating head 4 can smoothly adjust the capturing azimuth. After the adjustment is completed, the locking pressure ring 18 is closely attached to the upper end of the locking disc 3 under the action of the plurality of pressing springs 21 in the upper end parts of the plurality of telescopic sliding sleeves 19 and is locked with the locking disc 3, so as to lock the locking disc 3 and the azimuth rotating head 4 with each other, thereby ensuring the stability of the capturing azimuth of the UAV detection, recognition and positioning device.
