Description

Technical Field

[0001] The utility model relates to the technical field of radar, in particular to a low-altitude UAV detection radar. Background Art

[0002] In recent years, many UAV enthusiasts fly UAVs in no-fly areas near airports, resulting in flight diversions to other airports, returns, or delays, causing a large number of passengers to be stranded and seriously affecting the flight safety of civil aviation aircraft. To intercept UAVs, detection radars are required.

[0003] The patent with the publication number CN207301312U, named "A Rotary Low-Altitude UAV Detection Radar", includes a servo turntable, a junction box arranged at the edge of the side wall of the servo turntable, a support frame fixed on the top of the servo turntable, a servo motor arranged on the top of the servo turntable and connected to the support frame for providing horizontal rotation, and a radar component fixed on the support frame. Among them, the radar component includes an antenna base, an antenna cover, a first connector, a second connector, an antenna, a sum-difference device, a power module, a communication channel, a T / R module, a motherboard, and a processor. Through the above solution, the utility model has the advantages of simple structure, excellent heat dissipation performance, and a relatively wide detection coverage area, and has high practical value and promotion value in the field of active phased array radar technology.

[0004] In the prior art such as the above patent, the detection radar is fixedly installed outdoors by bolts. If all the bolts are removed to take down the radar to be repaired and then the repaired radar is installed by bolts, a lot of time is required for this work. During this process, the detection radar cannot work. At this time, if an aircraft needs to take off and the detection radar cannot detect UAVs, it may increase the risk of aircraft takeoff. Therefore, it is particularly important to be able to quickly remove and install the detection radar. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a low-altitude UAV detection radar to solve the deficiencies in the above prior art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A low-altitude UAV detection radar includes a mounting base having a placement groove, and a radar body is connected to the mounting base through a mounting mechanism. The mounting mechanism includes: at least one locking member, which includes a wedge block and an elastic member. The wedge block is horizontally slidably connected to the mounting base through a slide rod. During the sliding stroke of the wedge block relative to the mounting base, there is a locking position protruding into the placement groove; a connecting member, which includes a circular bottom plate. The connecting member is arranged on the radar body. During the process of the bottom plate being placed into the placement groove, it squeezes and passes over the wedge block, and the elastic force of the elastic member drives the wedge block to slide to the locking position to block above the bottom plate.

[0007] Further, one end of the sliding rod away from the wedge block is rotatably connected with a rotating rod. During the rotation stroke of the rotating rod, there is a blocking working position where it is blocked by the blocking block of the mounting seat, so that the wedge block is kept in a state of disengaging from the locking working position. When there is one or more locking parts, it is convenient for a worker to disassemble the radar body through the rotating rod.

[0008] Further, a rotating plate is rotatably connected to the bottom plate through a support column. At least one bracket is fixedly connected to the rotating plate. A connecting frame is rotatably connected to the bracket, and a fixed connection is established between the connecting frame and the radar body; further included are a first driving member and a second driving member. The first driving member is used to drive the rotating plate to rotate relative to the bottom plate, and the second driving member is used to drive the connecting frame to rotate relative to the bracket. A rotating rod rotates on the bracket. The rotating rod is welded to the connecting frame. The rotation connection between the connecting frame and the bracket and the rotation cooperation of the rotating plate relative to the bottom plate can adjust the angle of the radar body.

[0009] Further, the first driving member includes a first driving motor, and the rotating shaft of the first driving motor is fixedly connected coaxially with the rotating plate. The second driving member includes a second driving motor, and the rotating shaft of the second driving motor is fixedly connected to the connecting frame. The rotation of the rotating plate driven by the first driving motor and the rotation of the connecting frame driven by the second motor cooperate to adjust the angle of the radar body, making the angle of the radar detecting the unmanned aerial vehicle better.

[0010] Further, a protective pad is provided at the bottom of the bottom plate. When the protective pad is a moisture-proof pad, when the bottom plate is placed on the ground, the moisture-proof pad can be used to prevent moisture and isolate the damage of moisture to the bottom plate. When the protective pad is a buffer pad, when the bottom plate is placed in the placement groove, the buffer pad can protect the bottom plate and the placement groove when encountering a bumpy road section.

[0011] Compared with the prior art, for a low-altitude unmanned aerial vehicle detection radar provided by the present utility model, when the radar needs to be installed outdoors, only by placing the bottom plate on the radar body into the placement groove of the mounting seat, the bottom plate can be automatically locked by the locking parts, thereby fixing the radar body. When the radar needs to be removed from the mounting seat, only by pulling the wedge block can the locking be released, realizing the quick and convenient installation of the radar or the disassembly of the radar from the vehicle, and thus facilitating the work of the worker.

[0019] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] Please refer to Figure 1 , a low-altitude UAV detection radar provided by the embodiment of the present utility model includes a radar body and a mounting seat 1 having a placing groove 11. The radar body is an existing technical device and will not be described in detail here. The radar body 2 is connected to the mounting seat 1 through a mounting mechanism.

[0021] As shown in Figure 2 , the above-mentioned mounting mechanism includes: two locking members and a connecting member. Each locking member includes a wedge block 12 and an elastic member 13. Here, the elastic member 13 is a spring. The wedge block 12 is horizontally slidably connected to the mounting seat 1 through a slide bar 121. During the sliding stroke of the wedge block 12 relative to the mounting seat 1, there is a locking position protruding into the placing groove 11. The connecting member includes a circular bottom plate 3. The connecting member is provided on the radar body 2. During the process of the bottom plate 3 being placed into the placing groove 11, it squeezes and passes over the wedge block 12, and the elastic force of the elastic member 13 drives the wedge block 12 to slide to the locking position to block above the bottom plate 3.

[0022] When the radar needs to be fixed on the mounting base 1, first move the bottom plate 3 so that the bottom plate 3 is directly above the placement groove 11 of the mounting base 1, and then slowly lower the bottom plate 3. At this time, the bottom plate 3 will abut against the wedge block 12 inside the mounting base 1. After the wedge block 12 receives the abutting force, it will slowly disengage from the locking position until it completely disengages from the locking position. As the bottom plate 3 continues to descend, it will contact the inner bottom wall of the placement groove 11. Then, due to the force of the elastic member 13, the wedge block 12 will return to the locking position to complete the locking of the locking member to the bottom plate 3, thereby fixing the radar body 2 on the mounting base 1. When replacing the radar, pull the sliding rod 121. The movement of the sliding rod 121 drives the wedge block 12 to move and the wedge block 12 simultaneously squeezes the elastic member 13. After the wedge block 12 moves to disengage from the locking position, it is only necessary to lift the bottom plate 3 out of the placement groove 11. Then, release the pulling force on the sliding rod 121, and the wedge block 12 will return to the locking position again under the action of the elastic member 13 to quickly lock the bottom plate 3 again. In this way, the disassembly of the radar body 2 is completed. This solution realizes the quick disassembly and installation of the radar body 2 compared with using bolts.

[0023] One end of the sliding rod 121 away from the wedge block 12 is rotatably connected to a rotating rod 4. As Figure 1 shown, during the rotation stroke of the rotating rod 4, there is a blocking position that abuts against the stop block 14 of the mounting base 1. That is, when the rotating rod 4 is pulled outwards to make the wedge block 12 horizontally move out of the locking position, rotate the rotating rod 4 so that the stop block 14 can block the rotating rod 4 to prevent the rotating rod 4 from horizontally moving back to its original position, so that the wedge block 12 remains in the state of disengaging from the locking position. When there is one or more locking members, it is convenient for a worker to disassemble the radar body 2 through the rotating rod 4. Among them, the way the stop block 14 blocks the rotating rod 14 can be as Figure 1 shown that the rotating rod 4 is pulled outwards beyond the end of the stop block 14, and the rotating rod 14 rotates and buckles on the end of the stop block 14, or a corresponding card slot can be opened on the stop block 14, and the rotating rod 14 rotates and is stuck in the card slot, etc.

[0024] As Figure 1 , Figure 2 , a rotating plate 5 is rotatably connected to the bottom plate 3 through a support column 31. Two brackets 51 are fixedly connected to the rotating plate 5. A rotating rod is rotatably connected between the two brackets 51. A connecting frame 6 is fixedly connected to the rotating rod. A fixed connection is made between the connecting frame 6 and the radar body 2. The connecting frame 6 is rotatably connected to the bracket 51 and the rotating plate 5 rotates relative to the bottom plate 3 in a cooperating manner, which can adjust the angle of the radar body 2.

[0025] It also includes a first driving member and a second driving member. The first driving member is used to drive the rotating plate 5 to rotate relative to the bottom plate 3, and the second driving member is used to drive the connecting frame 6 to rotate relative to the bracket 51.

[0026] Among them, as Figure 4, the first driving member includes a first driving motor 7, the rotating shaft of the first driving motor 7 is fixedly connected to the rotating plate 5 coaxially, and the installation method of the rotating plate 5 rotatably installed on the bottom plate 3 belongs to the prior art and will not be elaborated here; the second driving member includes a second driving motor 8, the rotating shaft of the second driving motor 8 is fixedly connected to the connecting frame 6 through a rotating rod, and the first driving motor 7 drives the rotating plate 5 to rotate and the second motor drives the connecting frame 6 to rotate in cooperation to adjust the angle of the radar body 2 so that the angle of the radar detecting the unmanned aerial vehicle is better.

[0027] A protective pad (not shown in the figure) is provided at the bottom of the bottom plate 3. When the protective pad is a moisture-proof pad, when the bottom plate 3 is placed on the ground, the moisture-proof pad can be used to prevent moisture and isolate the damage of moisture to the bottom plate 3. When the protective pad is a buffer pad, when the bottom plate 3 is placed in the placement groove 11, the buffer pad can protect the bottom plate 3 and the placement groove 11 when encountering a bumpy road section.

[0028] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
