[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In order to prevent the detection device from directly hitting the ground when tipping over, a protective effect is provided for the detection body 2 to improve the safety of the detection device, such as Figure 1 - Figure 7 As shown, the present embodiment provides a UAV detection device based on spectrum recognition, which consists of a bracket 1, a detection body 2 and a positioning mechanism 3. The detection body 2 is arranged on the top of the bracket 1, and the bracket 1 can be folded and stored. The detection body 2 detects the UAV by analyzing and identifying the radio spectrum signal between the UAV and the remote control. The positioning mechanism 3 is arranged on the top of the bracket 1 and is used to install detection bodies 2 of different specifications and provide protection for them; specifically, the positioning mechanism 3 includes a support seat 30 fixedly arranged on the top of the bracket 1, and six movable clamping rods 31 distributed in a circular array and slidably arranged on the support seat 30. A protective pad is fixedly bonded to the middle part of one side of the movable clamping rod 31, which can provide a certain shock absorption and protection effect for the detection body 2. The six movable clamping rods 31 can fix and install detection bodies 2 of different specifications, which can expand the application scope of the positioning mechanism 3.

[0039] A protective cover 32 is detachably provided on the top of the support seat 30, and a movable pressure plate 33 for supporting the detection body 2 is provided on the top of the protective cover 32. An anti-skid pad 36 is fixedly provided on the top of the movable pressure plate 33. When the detection body 2 is placed on the movable pressure plate 33, it contacts the anti-skid pad 36, thereby increasing the friction between the movable pressure plate 33 and the detection body 2, making the detection body 2 more stable when installed. A sealing baffle 34 located at the bottom of the protective cover 32 and sliding with the support seat 30 is fixed on one side of the bottom of the movable clamping rod 31. The protective cover 32 and its surroundings are Six sealing baffles 34 protect the inner side of the support seat 30, and a protective cover 35 detachably connected to the support seat 30 is provided on the side of the bottom of the movable clamping rod 31 away from the protective cover body 32. When the detection body 2 falls, the protective cover 35 on the support seat 30 first contacts the ground to prevent the detection body 2 from directly hitting the ground. At the same time, the six movable clamping rods 31 also provide protection for the detection body 2, so as to provide multiple protections for the detection body 2, thereby improving the safety of the detection device and avoiding the situation where the existing detection device falls on the ground and is damaged when it falls.

A transmission assembly 38 for synchronously driving the six movable clamping rods 31 to move toward the center is provided on the inner side of the support seat 30. The specific implementation method is that the rotating assembly 37 includes a threaded vertical sleeve 371 rotatably provided at the inner center position of the support seat 30 through a bearing, and the top of the threaded vertical sleeve 371 passes through the protective cover body 32 and is rotatably connected thereto, and the inner side thread of the threaded vertical sleeve 371 is provided with a threaded vertical shaft 372 whose top is fixed to the movable pressure plate 33. A transmission gear 373 is fixedly set on the outer side of the threaded vertical shaft 372. The detection body 2 is placed on the movable pressure plate 33. The detection body 2 squeezes the movable pressure plate 33, and the movable pressure plate 33 pushes the threaded vertical shaft 372 to move downward. The threaded vertical shaft 372 rotates inside the threaded vertical sleeve 371, so that the threaded vertical shaft 372 drives the threaded vertical sleeve 371 outside it to rotate, and the threaded vertical sleeve 371 drives the transmission gear 373 thereon to rotate, thereby driving the transmission gear 373 to rotate, so as to drive the transmission component 38 to operate, making the detection body 2 more convenient and reducing the inconvenience of the staff.

[0042] The transmission assembly 38 includes transmission racks 381 respectively fixedly arranged on one side of the bottom of the six movable clamping rods 31, and one end of the transmission rack 381 is meshed with the transmission gear 373. Two opposite transmission racks 381 are staggered left and right, and two adjacent transmission racks 381 are staggered up and down, which can ensure that the six transmission racks 381 can move stably and will not be affected. A reset baffle 382 that slides with the support seat 30 is fixedly arranged in the middle of one side of the transmission rack 381, and a limit spring 383 is fixedly arranged on one side of the reset baffle 382. One end of the limit spring 383 is fixedly arranged with a fixed spring 383 that is fixed with the support seat 30. The limit baffle 384, when the transmission gear 373 rotates, the transmission gear 373 simultaneously drives the six transmission racks 381 to move, and the six transmission racks 381 respectively drive the movable clamping rods 31 at one end thereof to move, and the six movable clamping rods 31 move toward the middle of the support seat 30, and at the same time the transmission rack 381 also drives the reset baffle 382 to move, and the reset baffle 382 squeezes the limit spring 383, and the limit spring 383 produces elastic deformation and is compressed, clamping the detection body 2 on the support seat 30. The structure is simple and reasonable, and the transmission is stable, which ensures the stability of the installation of the detection body 2 and improves the practicability of the detection device.

[0043] Third embodiment

[0044] In order to further fix the detection body 2 and ensure that the detection body 2 is safer when in use, Figure 5 and Figure 7As shown, in this embodiment, a clamping assembly 39 for pressing the detection body 2 onto the support seat 30 is provided on the movable clamping rod 31.

The bottom of the movable protrusion 396 is provided with an anti-skid plate 397 that contacts the top edge of the detection body 2. The top of the anti-skid plate 397 is fixed with a buffer spring 398 that is fixed to the movable protrusion 396. When the anti-skid plate 397 contacts the top edge of the detection body 2, the anti-skid plate 397 squeezes the buffer spring 398. The buffer spring 398 produces elastic deformation and is compressed. While providing a buffer for the detection body 2, it can also compress the detection body 2 of different thicknesses, thereby expanding the application range of the positioning mechanism 3.

[0045] In actual use of the drone detection device, firstly, the bracket 1 with a suitable height adjusted is placed on a flat ground, and then the detection body 2 is placed on the movable pressure plate 33, the detection body 2 squeezes the movable pressure plate 33, the movable pressure plate 33 pushes the threaded vertical shaft 372 to move downward, the threaded vertical shaft 372 rotates inside the threaded vertical sleeve 371, so that the threaded vertical shaft 372 drives the threaded vertical sleeve 371 outside thereof to rotate, the threaded vertical sleeve 371 drives the transmission gear 373 thereon to rotate, and the transmission gear 373 drives the six transmission racks 381 to move at the same time, and the six transmission racks 381 respectively drive the movable clamping rod 31 at one end thereof to move, and the six movable The clamping rod 31 moves toward the middle of the support seat 30, and the six movable clamping rods 31 clamp and fix the side of the detection body 2.
