DETAILED DESCRIPTION

[0045] See also Figure 1 In an embodiment of the present invention, a highly integrated anti-UAV turntable includes:

[0046] Support base 1;

[0047] A control unit 11 is arranged directly above the support base 1;

[0048] The speed control and adjustment component 2 is coaxially fixed on the support base 1, and the control unit 11 is installed on the speed control and adjustment component 2;

[0049] The mounting frame 12 has an inverted U-shaped cross section. The mounting frame 12 is relatively rotatably mounted on the control unit 11, and a speed control and adjustment component 2 is correspondingly arranged between the mounting frame 12 and the control unit 11;

[0050] A tracking probe 13 is fixed to one side of the upper end surface of the mounting frame 12; and

[0051] The radar monitoring device (not shown in the figure) is installed on the control unit 11, so that the radar monitoring device performs preliminary capture and then the tracking probe performs continuous tracking to realize integrated anti-UAV work.

[0052] In this embodiment, the speed control and adjustment component 2 includes:

[0053] A middle shaft 21 is vertically fixed to the middle of the upper end surface of the support base 1;

[0054] A main drive device 3 is coaxially mounted on the support base 1, and the main drive device 3 is rotatably mounted on the central shaft 21;

[0055] The auxiliary driving device 4 is relatively rotatably mounted on the main driving device 3, and the control unit 11 is fixed on the auxiliary driving device 4; and

[0056] The gradual speed regulation component 5 is arranged on the main drive device 3, and the output end of the gradual speed regulation component 5 is connected to the auxiliary drive device 4, which is used to drive the auxiliary drive device 4 to deflect the center of the circle, wherein the main drive device and the auxiliary drive device can rotate independently or synchronously, and their rotation directions can be set in opposite directions or in the same direction. The corresponding gradual speed regulation component can realize zero-point speed-up operation, so as to achieve seamless connection in the synchronous rotation of the main drive device and the auxiliary drive device. For example: when the device body needs to rotate at 10° / s, at this time, if the main drive device moves at a maximum of 8° / s, at this time, the gradual speed regulation component accelerates from zero point to 8° / s, and stops moving after running for 1s, the main drive device starts to rotate, and then the gradual speed regulation component accelerates from zero point to 2° / s, and the auxiliary drive device correspondingly rotates at 2° / s (at this time the gradual speed regulation component stops moving).

[0057] As a preferred embodiment, the main driving device 3 can form a first speed in a rotating state, and the auxiliary driving device 4 can form a second speed in a rotating state;

[0058] Furthermore, the first speed is greater than the second speed, and both the first speed and the second speed are set to a three-speed adjustable mode, with various mixing modes and strong adaptability.

[0059] In this embodiment, the main driving device 3 includes an internal gear seat 31, which is coaxially arranged on the support base 1. A driving motor is provided on one side of the support base 1. A transmission tooth 32 is installed at the output end of the driving motor. The transmission tooth 32 is meshed with the internal gear seat 31 for transmission.

[0060] The auxiliary driving device 4 includes an outer fixed disk 41, which is fixed concentrically on the inner gear seat 31. A worm wheel 42 is rotatably arranged inside the outer fixed disk 41, and a worm body 43 is rotatably arranged on one side of the outer fixed disk 41. The worm body 43 is meshed with the worm wheel 42 for transmission with high precision, so that the system pointing accuracy can reach 0.05°.

[0061] In this embodiment, the gradual speed regulation component 5 includes:

[0062] A sealing branch pipe 51 is fixed above the main driving device 3, and the cross section of the sealing branch pipe 51 is an arc-shaped structure;

[0063] An inner plug 52 is slidably disposed in the sealing branch pipe 51, one end of the inner plug 52 is connected to the auxiliary driving device 4, and an outer spring is sleeved on one side of the inner plug 52 located on the sealing branch pipe 51;

[0064] A liquid storage tank 53 is transversely fixed on the main drive device 3, and the liquid storage tank 53 stores pressurized oil. A plug pusher 56 is slidably disposed in the liquid storage tank 53;

[0065] A transmission screw 54 is rotatably disposed on the liquid storage bin 53, a guide member 55 is slidably sleeved on the transmission screw 54 through threaded engagement, and one end of the guide member 55 is fixed to the plug pusher 56 through a support rod; and

[0066] The inner connecting tube 57 is connected to one end of the liquid storage tank 53, and one end of the inner connecting tube 57 is connected to the sealing branch pipe 51. That is to say, the push plug is driven to move laterally through the rotation of the transmission screw, so as to deliver the pressurized oil to the sealing branch pipe, and the auxiliary drive device is driven by the steering displacement of the inner plug to deflect relative to the main drive device.

[0067] In this embodiment, it also includes:

[0068] A current collecting seat 58 connected to the inner connecting pipe 57;

[0069] There are multiple shunt pipes 59 arranged in an array, each of which is connected to the current collecting seat 58, and one end of the shunt pipe 59 is connected to the sealing branch pipe 51;

[0070] An outer ring sleeve 6 is sleeved outside the sealing branch pipe 51. A ring plug is provided on the outer ring sleeve 6 for sliding sealing via a supporting spring 61. The ring plug is slidably sleeved outside the sealing branch pipe 51.

[0071] The discharge piece is laterally connected between the shunt pipes 59, one end of the discharge piece is connected to the outer ring sleeve 6, and each of the shunt pipes 59 is provided with a three-way valve 510, and the three-way valve 510 is connected to the discharge piece. Especially in the initial use, when the gradual speed regulation component accelerates from zero point, the transmission screw drives the plug pusher to move laterally at a uniform speed, and one of the three-way valves is connected to the sealing branch pipe (the rest is connected to the outer ring sleeve through the discharge piece), runs for 2 seconds, and then opens one of the two three-way valves, so that the two three-way valves are connected to the sealing branch pipe (there is still one connected to the outer ring sleeve through the discharge piece), runs for 2 seconds, and finally opens the remaining three-way valve, thereby realizing the acceleration of the steering displacement of the inner plug.

[0072] As a preferred embodiment, each of the three-way valves 510 can control each of the branch pipes 59 to transport the pressurized oil in the manifold 58 to the outer ring sleeve 6 or the sealing branch pipe 51 .

[0073] In this embodiment, a side bin 7 is further provided on one side of the liquid storage bin 53, a driving disk 71 is rotatably provided in the side bin 7, a transmission rod is hinged on the driving disk 71, a sliding plug is further provided in the side bin 7, and the transmission rod is connected to the sliding plug;

[0074] Furthermore, a telescopic guide rod 72 is provided in the middle of the inner plug 52, a displacement sensor 73 is provided at one end of the telescopic guide rod 72, and a receiver 74 is fixed at the other end thereof;

[0075] The telescopic guide rod 72 is provided with a limit spring on its outer sleeve, especially before use, in order to prevent the inner plug from being affected by the friction of the inner wall of the sealing branch pipe, resulting in immobility under small displacement variables, the driving disk reciprocates to drive the sliding plug to move (at this time, the telescopic guide rod is in a flexible extension and retraction state), and the displacement of the inner plug is measured by the displacement sensor, thereby improving the use accuracy (the above problem can be solved by replacing the inner plug or replacing the boost oil).

[0076] In this embodiment, the pitch axis adjustment range of the tracking probe 13 is from -10° to 80°.

[0077] Specifically, during use, the radar monitoring equipment is used for preliminary capture, and then the tracking probe is used for continuous tracking. At this time, the pitch and steering of the tracking probe are precisely controlled by the corresponding speed control and adjustment components, wherein the main drive device rotates to form a first speed and the auxiliary drive device rotates to form a second speed, both of which are set to a three-speed adjustment mode, so that angular velocity acceleration or deceleration movement can be performed in a variety of combinations, with a strong mixing effect and a wide range of use; in particular, the gradual speed adjustment component can provide a precise corner zero-point acceleration effect, so that the first speed and the second speed can be seamlessly connected to avoid a sense of gap.

[0078] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
