Description

Technical Field

[0001] This utility model relates to the field of intelligent monitoring, specifically to a turntable for search and tracking. Background Technology

[0002] Drone technology is being used more and more in various industries. For some important buildings and special areas, it is necessary to deploy equipment that can intelligently monitor, search, analyze and strike threat targets to ensure regional security.

[0003] Existing products integrating radar, visible light, thermal imaging, laser, and radio jamming components use two motors to drive each segment of the pitch axis. The thermal imaging and laser strike components are mounted on the left side of the device, responsible for infrared monitoring and hard strikes against threats. The visible light and radio jamming components are mounted on the right side of the device, responsible for imaging threats and signal interference. When the device operates at night, requiring the thermal imaging component to work in conjunction with the laser component for hard strikes, or the thermal imaging and radio jamming components to work in conjunction with the laser component for hard strikes simultaneously, the functional components on both sides need to point towards the target. In this case, the independent rotation of the two motors will generate tracking errors, reducing the accuracy of the device's strikes. A similar technical solution can be found in the utility model patent with authorization announcement number CN221406034U. Utility Model Content

[0008] Furthermore, the base includes a bottom shell and a chassis located at its bottom end. A slot is provided in the middle of the chassis, and the lower end of the hollow support shaft is fixed in the slot. The fixed shaft is a hollow structure, and the upper end of the hollow support shaft is anti-rotationally assembled with the inner side of the fixed shaft.

[0009] Furthermore, the radar turntable is a one-dimensional turntable, and the radar assembly includes a radar base and a radar body; the fixed base is equipped with a third motor and a second azimuth rotating shaft, the upper end of the second azimuth rotating shaft is connected to the radar base, and the second azimuth rotating shaft is driven by the third motor.

[0010] Furthermore, the hollow support shaft has a radial hole near the bottom for threading cables. The cables can pass through the hollow support shaft and the fixed shaft in sequence before entering the radar turntable.

[0011] Furthermore, a conductive slip ring is fitted on the outer side of the hollow support shaft.

[0012] Furthermore, the first mounting structure is used to mount a first functional component, the first functional component including a laser component; the first mounting structure is also used to mount a second functional component, the second functional component including an infrared thermal imaging component, a visible light camera component, and a radio directional jamming component.

[0035] 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 skilled in the art are within the protection scope of the present utility model.

[0036] Embodiments of this utility model:

[0037] like Figure 1 As shown, a search and tracking turntable includes a two-dimensional turntable and a one-dimensional turntable, forming a three-axis turntable structure. The two-dimensional turntable is used to drive the azimuth rotation and pitch movements of the laser assembly 4, the infrared thermal imaging assembly 5, the visible light camera assembly 6, and the radio directional jamming assembly 7. The one-dimensional turntable does not rotate with the two-dimensional turntable; it rotates independently and is used to drive the radar assembly 8.

[0038] like Figure 1 and 2 As shown, the two-dimensional turntable includes a base 1 and a rotating platform 2. The rotating platform 2 is rotatably mounted on the base 1 via a first directional rotating shaft 15, which is driven by a first motor 17. The base 1 includes a bottom shell 11 and a chassis 12 located at its bottom end, and the chassis 12 is detachably connected to the bottom shell 11. The first directional rotating shaft 15 is a hollow structure, similar to a sleeve, and is mounted in the bottom shell 11 via a first crossed roller bearing 19.

[0039] like Figure 4 As shown, the bottom of the base shell 11 is provided with a mechanical interface 111 for mounting and fixing equipment. The mechanical interface 111 is a slotted hole, which is radially and evenly distributed in a circumferential manner, making installation and adjustment simple.

[0040] like Figure 1 and 2As shown, the rotating platform 2 is equipped with a pitch shaft. A first mounting structure 24 and a second mounting structure 25 are respectively provided at both ends of the pitch shaft. The first mounting structure 24 and the second mounting structure 25 are used to connect corresponding functional components. The pitch shaft is driven by a second motor 29 located within the rotating platform 2. In this embodiment, the pitch shaft is designed as two shafts, including a first pitch shaft 21 and a second pitch shaft 22 connected together by a coupling sleeve 27. The first pitch shaft 21 and the second pitch shaft 22 are coaxially assembled and driven by the same second motor 29. The second motor 29 is connected to the second pitch shaft 22. In other embodiments, the second motor 29 can also be connected to the first pitch shaft 21. The coupling sleeve 27 is a hollow structure with a through-hole in the middle.

[0041] like Figure 2 As shown, the rotating platform 2 includes a rotating housing 23, which has through holes in the top and bottom and in the left and right for mounting corresponding components. The first pitch axis 21 and the second pitch axis 22 are respectively assembled in the rotating housing 23 by an angular contact ball bearing 28.

[0042] like Figure 2 As shown, the rotating table 2 is equipped with a limiting structure, using a limiting block 26, to limit the rotation range of the coupling sleeve 27. Under normal circumstances, the rotation angle of the coupling sleeve 27 is controlled by the motor. In the event of a control failure, the limiting block 26 can prevent it from rotating further.

[0043] like Figure 1 As shown, the left and right ends of the rotating housing 23 are provided with lifting slots 201. The lifting slots 201 are annular slots. With the help of the lifting slings, the overall center of gravity of the equipment is below the height of the pitch axis, ensuring that the equipment is stable and does not overturn during the lifting process.

[0044] like Figure 2 , 3 As shown in Figure 6, the rotating platform 2 also includes a vertically placed hollow support shaft 13. A slot is provided in the middle of the chassis 12, and the lower end of the hollow support shaft 13 is fixed in the slot with a first tightening sleeve 141. The hollow support shaft 13 passes through the clearance opening of the coupling sleeve 27, which ensures that the coupling sleeve 27 does not interfere with the hollow support shaft 13 when rotating within a certain angle range. Figure 3As shown, the fixed shaft 18 is a hollow structure. The upper end of the hollow support shaft 13 is anti-rotationally fitted to the inner side of the fixed shaft 18, specifically through a second expansion sleeve 142 and a transition sleeve 143. The central hole of the transition sleeve 143 is wider at the top and narrower at the bottom, which can accommodate and support the second expansion sleeve 142. The upper end of the hollow support shaft 13 and the transition sleeve 143 are tightly connected by the second expansion sleeve 142. The transition sleeve 143 is located on the lower inner side of the fixed shaft 18. The central hole of the fixed shaft 18 is a stepped hole. The fixed shaft 18 and the transition sleeve 143 are tightly fitted, and the transition sleeve 143 can support the fixed shaft 18. A second crossed roller bearing 20 is fitted on the outer periphery of the fixed shaft 18. The outer periphery of the second crossed roller bearing 20 contacts the inner wall of the upper hole of the rotating housing 23. When the first directional rotating shaft 15 rotates, the fixed shaft 18 does not move accordingly.

[0045] like Figure 1 and 2 As shown, the one-dimensional turntable is the radar turntable 3, which is used to mount the radar assembly 8. The radar turntable 3 includes a fixed base 31; the bottom of the fixed base 31 is connected to the upper end of the fixed shaft 18 via a lower adapter flange 32, which supports it. The fixed shaft 18 is not of uniform diameter; the upper outer diameter is larger to provide stable support for the lower adapter flange 32.

[0046] like Figure 1 and 4 As shown, radar assembly 8 includes radar mount 82 and radar body 81, with the working surface of radar body 81 at a specific elevation angle to the horizontal plane. Figure 2 As shown, the fixed base 31 is equipped with a third motor 37 and a second azimuth rotating shaft 33. The upper end of the second azimuth rotating shaft 33 is connected to the radar base 82 through an upper adapter flange 34. The second azimuth rotating shaft 33 is driven by the third motor 37. The second azimuth rotating shaft 33 is assembled in the fixed base 31 through a third crossed roller bearing 36. The second azimuth rotating shaft 33 can rotate independently and can be used together with the two-dimensional follower turntable below to form a three-axis turntable. It can also be disassembled and used as an independent turntable.

[0047] like Figure 2 As shown, a first slip ring 16 is fitted on the outer side of the hollow support shaft 13. The first slip ring 16 is a conductive slip ring and does not contact the hollow support shaft 13. The cables in the base 1 can be led to the rotating table 2 through the first slip ring 16 to supply power to the second motor 29.

[0048] like Figure 2 and 6As shown, the hollow support shaft 13 has a radial hole 131 near its bottom for threading cables. The cables pass through the hollow support shaft 13 and the fixed shaft 18 in sequence before entering the radar turntable 3 and connecting to the drive board 38. Part of the cable from the drive board 38 supplies power to the third motor 37, and another part extends upwards through the second slip ring 35 to the electrical interface 341. The location of the electrical interface 341 is shown in the image. Figure 4 As shown. Electrical interface 341 is responsible for power supply and communication of radar component 8. Electrical interface 341 is located on the outer side of the upper adapter flange 34, making it easy to plug and unplug.

[0049] like Figure 2 and 6 As shown, the first mounting structure 24 is used to mount the first functional component, which includes the laser component 4; the first mounting structure 24 is also used to mount the second functional component, which includes the infrared thermal imaging component 5, the visible light camera component 6, and the radio directional jamming component 7.

[0050] like Figures 7 to 9 As shown, the first mounting structure 24 has two first mounting slots 241, and the laser assembly 4 has a first hook 41 that mates with the first mounting slots 241. After mounting, they are reliably connected by screws. The second mounting structure 25 has a second mounting slot 251, and the second functional component has a second hook 51 that mates with the second mounting slot 251. The hook has a U-shaped opening facing downwards, which engages with the corresponding mounting slot.

[0051] This invention utilizes three drive motors across three sets of shaft systems. The radar component 8 rotates freely 360° in all weather conditions, capturing targets within its monitoring radius and reporting warnings. The visible light component can photograph and track detected targets during the day, while the thermal imaging component photographs and tracks them at night. The radio directional jamming component 7 can interfere with the signal reception of threatening targets, causing them to lose remote control connection or malfunction. The laser component delivers destructive strikes to threatening targets. Driven by the three shaft systems, the equipment control system coordinates the various functional components to achieve the monitoring, search, tracking, and strike capabilities of the detected targets.
