Description

Technical Field

[0002] With the increasing development of low-altitude areas, UAV technology has played a vital role in reconnaissance and surveillance, target indication, precision strikes, and electronic warfare. At the same time, for "low, slow, and small" UAV targets, it is crucial to quickly detect, discover, and counter the micro-UAVs that may appear in any corner. At this stage, laser radar can achieve fixed-point elimination of UAVs, but when encountering UAV swarms, its combat performance and efficiency are greatly reduced and cannot meet the needs of war. Using high-power microwave radar to scan and eliminate UAV swarms in the area, its large killing range, good directionality, and high power can greatly improve the combat performance of anti-UAVs. And because of the strong maneuverability and small size of UAVs, the tracking and positioning performance of radars is very high.

Obviously, the described embodiments are 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.

[0033] The embodiments of the present application provide a high-precision turntable for high-power microwave transmission, thereby solving the problem of using high-power microwaves to accurately track and quickly strike combat targets.

[0034] The technical solution in the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0035] In an embodiment of the present invention, the present invention provides a high-precision turntable for high-power microwave emission, and the high-precision turntable for high-power microwave emission includes: the radar antenna is connected to the turntable through the first pitch bracket and the second pitch bracket, and the first electric push cylinder and the second electric push cylinder are used to realize the conversion of the antenna working and transportation states; the first pitch bracket and the second pitch bracket are connected to the turntable through the pitch slewing support; the turntable is connected to the base through the azimuth slewing support and driven by the azimuth motor; the high-power microwave is input from the first feeder straight head through the feeder system, and is output from the first feeder elbow and transmitted to the radar antenna. The advantage of the present invention is that it can be used for high-power microwave emission to accurately track and quickly strike combat targets.

[0036] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] Embodiment 1:

[0038] like Figures 1 to 5 As shown, the present invention provides a high-precision turntable for high-power microwave transmission, which is introduced in sequence from radar antenna to base:

[0039] The radar antenna has a total of 4 fixed points, of which the two first pitch brackets 3 and the second pitch bracket 4 are connected to the turntable 11, and the other two are connected to the pitch drive rotation through the antenna ear 1 to realize the conversion of the antenna working and transportation states; the pitch drive includes two left and right drives, and the two drive structures are the same. The left drive includes the first electric push cylinder 2, the first pitch motor 14, the first pitch reducer 15, and the first pitch spiral reducer 16. The right drive includes the second electric push cylinder 13, the second pitch motor, the second pitch reducer, and the second pitch spiral reducer. The first electric push cylinder 2 and the second electric push cylinder 13 are respectively fixed with antenna ears 1 on the cylinder seats. The first electric push cylinder 2 and the second electric push cylinder 13 are arranged in parallel, and the two output ends are respectively fixed on both sides of the turntable 11 through the pitch ears 6. The pitch motor, the pitch reducer, and the pitch spiral reducer are all fixed on the cylinder seat of the corresponding electric push cylinder. The specific fixing structure is conventional technology and will not be described in detail. The pitch motor of the first electric push cylinder drives the pitch reducer, and the pitch reducer is reversed by the pitch spiral reducer. The output power of the pitch spiral reducer drives the pitch spiral reducer of the second electric push cylinder through the coupling 17, and then drives the second electric push cylinder to perform synchronous pitching action. In this embodiment, the first electric push cylinder and the second electric push cylinder are each equipped with a pitch motor, but they are driven by a single motor during normal working hours, and the other motor is used as a backup.

[0040] In this embodiment, the pitch axis is driven by an electric push cylinder, which greatly reduces the system weight and increases the system reliability compared to the traditional swing arm structure. The electric push cylinder uses a ball screw for transmission, and the inertia ratio of the pitch end reaches 1.5. It has a fast dynamic response and a small system delay, and can achieve high-precision follow-up tracking at the pitch end, greatly improving the radar performance.

[0041] The pitch bracket is connected to the turntable through the pitch slewing support; the turntable is connected to the base through the azimuth slewing support and is driven by the azimuth motor; high-power microwaves are input from the base through the feeder system, output by the pitch bracket and transmitted to the radar antenna.

[0042] The turntable 11 is a box structure as a whole, and a horizontal cylindrical structure extends above the box structure. The two pitch brackets 3 and 12 are rotatably connected to the two ends of the cylinder through the pitch slewing bearing 30. The pitch rotary transformer 28 and the pitch mounting bracket 29 are also fixed inside the box; the pitch rotary transformer 28 is installed inside the box through the pitch mounting bracket 29, and its main function is to provide real-time feedback on the pitch angle of the antenna; based on this function, the installation position of the pitch rotary transformer can meet this function.

[0043] like Figures 6 to 8As shown, one side of the first pitch bracket 3 is connected to the turntable through the pitch swivel support, and the other side is connected to the first feeder elbow through the support tube, and one side of the second pitch bracket is connected to the turntable through the pitch swivel support. The first pitch bracket and the second pitch bracket can be rotated 0 to 90 degrees through the pitch swivel support;

[0044] The feeder system includes: a first feeder elbow 4, a first feeder straight head 10, a second feeder elbow 18, a third feeder elbow 23, a first feeder rotating joint 24, a second feeder straight head 25, a second feeder rotating joint 26, and a fourth feeder elbow 27. The first feeder straight head 10 is connected to the base, and the first feeder elbow 4 is connected to the pitch bracket. The first feeder straight head 10 penetrates horizontally from the side of the base, and seals and connects the third feeder elbow 23, the second feeder straight head 25, the second feeder elbow 18, and the fourth feeder elbow 27 in sequence according to the microwave propagation direction; the third feeder elbow 23 is connected to the second feeder straight head 25 through the first feeder rotating joint 24, and the second feeder elbow 18 is connected to the fourth feeder elbow 27 through the second feeder rotating joint 26. The rotating joint in this embodiment is a collector ring. When the two pitch brackets rotate, the first feeder elbow 4 rotates synchronously with the pitch brackets, and with the cooperation of the rotating joints, the sealing performance and effect of the entire feeder system are not affected.

[0045] In this embodiment, in order to ensure the stability of the first feeder elbow 4, a support tube is horizontally extended from the outside of the pitch bracket to support the first feeder elbow 4, which can ensure the stability of the first feeder elbow 4 during rotation. High-power microwaves pass through the first feeder straight head, the third feeder elbow, the first feeder rotating joint, the second feeder straight head, the second feeder rotating joint, the fourth feeder elbow in sequence, and finally are transmitted to the radar antenna through the first feeder elbow.

[0046] like Fig. 9 As shown, the base includes a box body, an azimuth slewing bearing 31 is fixed on the top of the box body through an azimuth mounting bracket 21, an azimuth motor 8 is fixed on both sides of the box body, and the output end of the azimuth motor 8 faces upward. The azimuth drive unit composed of the azimuth motor 8 and the azimuth reducer 7 realizes azimuth rotation of 0 to 360 degrees by driving the azimuth gear 32 to engage with the azimuth slewing bearing 31. The azimuth rotary transformer 20 and the merge ring are installed inside the box body, and the azimuth latch is installed on the side of the base to complete the locking of the turntable during transportation. The first feeder straight head 10 is inserted from one side of the box body and connected to the third feeder elbow 23 inside the box body. The first feeder rotating joint 24 can realize the sealed rotation between the third feeder elbow 23 and the second feeder straight head 25.

[0047] In this embodiment, the second feeder straight end 25 extends upward from the center of the azimuth mounting bracket 21 and is sealed and rotatably connected to the second feeder elbow 18 in the turntable 11 through a rotating assembly 19, ie, a merge ring.

[0048] In this embodiment, the azimuth rotary transformer can provide real-time feedback of the azimuth angle of the antenna, and the slip ring completes the transmission of power, digital signals and other signals between the rotating part and the fixed part of the antenna.

[0049] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0050] In an embodiment of the present invention, the high-precision turntable for high-power microwave emission includes: the radar antenna is connected to the turntable through the first pitch bracket and the second pitch bracket, and the first electric push cylinder and the second electric push cylinder are used to realize the conversion of the antenna working and transportation states; the first pitch bracket and the second pitch bracket are connected to the turntable through the pitch slewing support; the turntable is connected to the base through the azimuth slewing support and driven by the azimuth motor; the high-power microwave is input from the first feeder straight head through the feeder system, output from the first feeder elbow and transmitted to the radar antenna. The advantage of the present invention is that it can be used for high-power microwave emission to accurately track and quickly strike combat targets.
