Technical Field

[0001] This invention relates to the field of drone countermeasure testing technology, and in particular to an automatic rotating laser countermeasure drone testing device. Background Technology

[0002] Drone laser countermeasures are a technology that uses high-energy laser beams to destroy or interfere with drones in a targeted manner. Through a closed-loop mechanism of "detection-tracking-strike", it can quickly intercept low-altitude drones. In the existing technology, after the production of high-power lasers for drone countermeasures is completed, multiple lasers from the same batch need to be selected for drone countermeasure tests.

[0003] In existing technologies, when conducting UAV countermeasure tests on high-power lasers under test, in order to facilitate the rotation and adjustment of the high-power laser during the test, it is necessary to fix the high-power laser under test on a fixture bracket, as disclosed in the invention patent with authorization announcement number CN118549092B. However, after completing the test of the current high-power laser, the current high-power laser must be removed before the next high-power laser under test can be installed and fixed. Moreover, the next test operation can only continue after the next high-power laser is installed. The test interval between adjacent sides is relatively long, which has a significant impact on the overall test efficiency.

[0004] Therefore, it is necessary to invent an automatic rotating laser counter-drone test device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic rotating laser countermeasure drone testing device that can complete the removal of laser A and the installation and positioning of laser C during the testing of laser B, thereby effectively shortening the interval between two adjacent tests and improving testing efficiency. This solves the problem mentioned in the background art that the existing testing method requires removing the current high-power laser after the test of the current high-power laser before installing and fixing the next high-power laser, and the next test operation can only continue after the installation of the next high-power laser is completed. The long interval between adjacent tests has a significant impact on the overall testing efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic rotating laser countermeasure drone test device, comprising a rotation adjustment component, a clamping and positioning component fixedly disposed on the top of the rotation adjustment component, a pushing component disposed on the clamping and positioning component, a transmission component fixedly disposed on the rear side of the rotation adjustment component, a laser support component slidably disposed on the inner side of the transmission component along the front-back direction, and a traction and pushing mechanism that is connected to the transmission component is disposed inside and on the rear side of the laser support component;

[0007] The laser support assembly includes a movable block that is slidably sleeved on the outside of two guide rods C. The top front of the movable block has a lower clearance groove, and the top of the movable block has an upper clearance groove that communicates with the lower clearance groove. A rotating cylinder is rotatably nested on the top of the movable block via a bearing. A drive gear is sleeved on the bottom outer side of the rotating cylinder via a one-way bearing. A shifting disk is fixedly sleeved on the top outer side of the rotating cylinder. U-shaped positioning frames adapted to the laser under test are fixedly installed at both ends of the top of the shifting disk.

[0008] The traction and pushing mechanism includes a moving plate that is driven and sleeved on the outside of the reciprocating screw and slidably sleeved on the outside of the two guide rods C. Connecting springs are fixedly connected to both sides of the bottom front of the moving plate. The front end of the connecting spring is fixedly connected to the back of the moving block. A connecting arm is fixedly installed on the top front of the moving plate. The connecting arm passes through the lower clearance groove and the upper clearance groove and enters the interior of the rotating cylinder. A pushing block is fixedly connected to the top of the connecting arm.

[0009] Preferably, the rotation adjustment assembly includes a base plate, a support base is fixedly disposed on the top of the base plate, a motor A is fixedly disposed at the bottom center of the support base, the output shaft of the motor A extends to the top of the support base and is fixedly connected to a lower U-shaped frame, a rotating shaft is rotatably nested on the inner side of the lower U-shaped frame through a bearing, and an upper U-shaped frame is fixedly sleeved on both outer ends of the rotating shaft.

[0010] Preferably, a driven gear is fixedly sleeved on the outer side of the rotating shaft, and a motor B is fixedly installed on the bottom inner side of the lower U-shaped frame. A driving gear that meshes with the driven gear is connected to the left side of the motor B.

[0011] Preferably, the clamping and positioning assembly includes a heat dissipation base fixedly disposed on the top of the upper U-shaped frame, a cooling water inlet pipe fixedly disposed through the right side of the front of the heat dissipation base, and a cooling water outlet pipe fixedly disposed through the left side of the front of the heat dissipation base.

[0012] Preferably, side plates are fixedly provided on both sides of the heat dissipation base, and an electric push rod A is fixedly provided on the outer side of the side plate. The output shaft of the electric push rod A extends to the inner side of the side plate and is fixedly connected to a clamping plate. A guide rod A that slides through the side plate is fixedly provided on the outer side of the clamping plate.

[0013] Preferably, a sight is fixedly provided on the outer side of any one of the side plates.

[0014] Preferably, the ejection assembly includes a crossbeam fixedly disposed on the front side of the top of the heat dissipation base, an electric push rod B fixedly disposed in the center of the front of the crossbeam, the output shaft of the electric push rod B extending to the rear side of the crossbeam and fixedly connected to an ejection plate, and guide rods B that slide through the crossbeam fixedly disposed on both sides of the front of the ejection plate.

[0017] The technical effects and advantages of this invention are as follows:

[0018] This invention incorporates a laser support component and a traction and pushing mechanism. When the traction and pushing mechanism moves the laser support component backward, it avoids interfering with the rotation adjustment component's ability to drive the laser under test. Simultaneously, the laser support component, in conjunction with the transmission component, can perform a post-test laser-to-test laser swapping operation. When the traction and pushing mechanism subsequently moves the laser support component forward, it not only aligns with the clamping and positioning component but also pushes the laser under test into the clamping and positioning component for secure clamping. Compared to existing technologies, this invention allows for the removal of laser A and the installation and positioning of laser C during the testing of laser B, effectively shortening the interval between adjacent tests and significantly improving testing efficiency.

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] This invention provides, for example Figures 1-5 An automatic rotating laser countermeasure drone test device is shown, including a rotation adjustment component 1, a clamping and positioning component 2 fixedly mounted on the top of the rotation adjustment component 1, a push-out component 3 mounted on the clamping and positioning component 2, a transmission component 4 fixedly mounted on the rear side of the rotation adjustment component 1, a laser support component 5 slidably mounted on the inner side of the transmission component 4 in the front-back direction, and a traction and pushing mechanism 6 that is connected to the transmission component 4 is mounted inside and on the rear side of the laser support component 5.

[0027] like Figure 2As shown, the rotary adjustment assembly 1 includes a base plate 11 made of Q235 low-carbon steel, which is high-strength, deformation-resistant, has a strong load-bearing capacity, and is low in cost, making it suitable as a foundation for equipment. A support base 12 is fixedly installed on the top of the base plate 11, and a motor A13 is fixedly installed at the center of the bottom of the support base 12. The output shaft of the motor A13 extends to the top of the support base 12 and is fixedly connected to a lower U-shaped frame 14. A rotating shaft 15 is rotatably nested inside the lower U-shaped frame 14 via bearings. An upper U-shaped frame 16 is fixedly sleeved at both ends of the outer side of the rotating shaft 15. Both the upper and lower U-shaped frames are made of 7075 aviation aluminum alloy, which is lightweight, corrosion-resistant, reduces rotational load, and improves adjustment response speed. A driven gear 17 is fixedly sleeved on the outer side of the rotating shaft 15. A motor B18 is fixedly installed at the bottom of the inner side of the lower U-shaped frame 14. A drive gear 19 that meshes with the driven gear 17 is connected to the left side of the motor B18.

[0028] Therefore, when motors A13 and B18 are started, motor A13 can drive the lower U-shaped frame 14 to rotate, and the lower U-shaped frame 14 can drive the upper U-shaped frame 16 to rotate through the rotating shaft 15. In turn, the upper U-shaped frame 16 drives the laser under test to rotate through the clamping and positioning assembly 2. Motor B18 can drive the rotating shaft 15 to rotate through the driving gear 19 and the driven gear 17. The rotating shaft 15 can drive the upper U-shaped frame 16 to rotate, and the upper U-shaped frame 16 drives the laser under test to rotate through the clamping and positioning assembly 2.

[0029] like Figure 3 As shown, the clamping and positioning assembly 2 includes a heat dissipation base 21 fixedly mounted on the top of the upper U-shaped frame 16. The base is made of 6063 aluminum alloy with a thermal conductivity of 201 W / (m·K). It has a serpentine water channel that can be machined inside, resulting in high heat dissipation efficiency and ensuring low-temperature operation of the laser under test. A cooling water inlet pipe 22 is fixedly installed through the right side of the front of the heat dissipation base 21, and a cooling water outlet pipe 23 is fixedly installed through the left side of the front of the heat dissipation base 21. Side plates 24 are fixedly mounted on both sides of the heat dissipation base 21. An electric push rod A25 is fixedly mounted on the outer side of the side plate 24. The output shaft of the electric push rod A25 extends to the inner side of the side plate 24 and is fixedly connected to a clamping plate 26. The clamping plate 26 is made of 6061 aluminum alloy and has a nitrile rubber pad bonded to its inner side. The aluminum alloy is lightweight and strong, and the rubber pad is non-slip and scratch-resistant, providing stable clamping force. A guide rod A27 that slides through the side plate 24 is fixedly mounted on the outer side of the clamping plate 26. A sight 28 is fixedly mounted on the outer side of any side plate 24.

[0030] By setting up the aforementioned rotation adjustment component 1 and clamping positioning component 2, after the laser under test enters between the two clamping plates 26, the two electric push rods A25 respectively drive the two clamping plates 26 to move inward, thereby clamping and fixing the laser under test A. Then, the laser under test A is connected to the control system of the aiming device 28, motor A13 and motor B18, and the control system controls the UAV to fly in the test area. Subsequently, the aiming device 28 performs reconnaissance and aiming at the UAV in the test area. The control system controls the motors A13 and B18 to start according to the reconnaissance data of the aiming device 28, thereby causing the lower U-shaped frame 14 to drive the laser under test A to rotate, and the upper U-shaped frame 16 to drive the laser under test A to rotate, so as to adjust the orientation of the laser under test A. After the adjustment is completed, the control system starts the laser under test A, thereby causing the laser under test A to emit a high-power laser to ablate and destroy the UAV. After the test is completed, the rotation adjustment component 1 is reset.

[0031] In addition, during the test, cooling water is continuously input into the heat dissipation base 21 through the cooling water input pipe 22, thereby cooling the laser under test. The cooled water is then output through the cooling water output pipe 23.

[0032] like Figure 3 As shown, the ejection assembly 3 includes a crossbeam 31 fixedly mounted on the front side of the top of the heat sink base 21. The crossbeam is made of 6061 aluminum alloy, which is rigid, provides stable support, and is lightweight. An electric push rod B32 is fixedly mounted in the center of the front of the crossbeam 31. The output shaft of the electric push rod B32 extends to the rear side of the crossbeam 31 and is fixedly connected to an ejection plate 33. The ejection plate 33 is made of 6061 aluminum alloy and has a Teflon coating on its inner side. The coating has a friction coefficient of ≤0.05, which ensures smooth and unobstructed pushing and avoids scratching the laser. Guide rods B34 that slide through the crossbeam 31 are fixedly mounted on both sides of the front of the ejection plate 33.

[0033] By setting up the above structure, after the laser under test is tested and the transposition disk 56 is docked with the heat dissipation base 21, the electric push rod B32 pushes the push plate 33, which is guided by the guide rod B34, to move backward. In turn, the push plate 33 pushes the laser under test to the inside of the U-shaped positioning frame 57 at the top front end of the transposition disk 56, so as to realize the output of the laser under test after the test.

[0034] like Figure 4 As shown, the transmission assembly 4 includes a fixed frame 41 located at the rear end of the base plate 11. It is welded from Q235 steel plate, has high overall rigidity, and supports the transmission components stably. A motor C42 is fixedly installed in the center of the front of the fixed frame 41. A reciprocating screw 43, which is connected to the motor C42, is rotatably nested inside the fixed frame 41 through a bearing. Guide rods C44 are fixedly installed on both sides inside the fixed frame 41. A back plate 45 is fixedly installed at the top rear end of the fixed frame 41. A drive rack 46 is fixedly installed on the right side of the front of the back plate 45.

[0035] By setting up the above structure, when the motor C42 drives the reciprocating screw 43 to rotate, the moving plate 61, guided by the guide rod C44, moves forward or backward.

[0036] like Figure 5 As shown, the laser support assembly 5 includes a movable block 51 slidably sleeved on the outside of the two guide rods C44. The movable block 51 is made of PA66+30% glass fiber reinforced engineering plastic, which has good self-lubrication, wear resistance, lightweight, and smooth sliding. The top of the movable block 51 has a lower clearance groove 52, and the top of the movable block 51 has an upper clearance groove 53 that communicates with the lower clearance groove 52. The top of the movable block 51 is rotatably nested with a rotating cylinder 54 made of 45 steel. The bottom of the outer side of the rotating cylinder 54 is sleeved with a drive gear 55 through a one-way bearing. The top of the outer side of the rotating cylinder 54 is fixedly sleeved with a shifting plate 56. Both ends of the top of the shifting plate 56 are fixedly equipped with U-shaped positioning frames 57 that are adapted to the laser under test.

[0037] By setting the above structure, the drive gear 55 meshes with the drive rack 46 during the backward movement of the moving block 51. When the moving plate 61 continues to move backward, the drive rack 46 drives the rotating cylinder 54 to rotate through the drive gear 55, which in turn drives the transposition disk 56 to rotate until the transposition disk 56 rotates 180 degrees. At this time, the laser after testing and the laser under test are transposed. When the moving block 51 moves forward, the drive rack 46 cannot drive the rotating cylinder 54 to rotate due to the limitation of the one-way bearing between the drive gear 55 and the rotating cylinder 54.

[0038] like Figure 5 As shown, the traction and pushing mechanism 6 includes a moving plate 61 that is sleeved on the outside of the reciprocating screw 43 and slidably sleeved on the outside of the two guide rods C44. The moving plate 61 is made of 6061 aluminum alloy, which is lightweight and provides stable support. Connecting springs 62 are fixedly connected to both sides of the bottom front of the moving plate 61. The front end of the connecting springs 62 is fixedly connected to the back of the moving block 51. A connecting arm 63 is fixedly installed on the top front of the moving plate 61. The connecting arm 63 passes through the lower clearance groove 52 and the upper clearance groove 53 and enters the interior of the rotating cylinder 54. A pushing block 64 is fixedly connected to the top of the connecting arm 63. The pushing block 64 is made of POM (polyoxymethylene), which has good self-lubrication, low coefficient of friction, and moderate hardness, and will not scratch the shell of the laser being tested.

[0039] By setting the above structure, when the moving plate 61 moves forward, the two connecting springs 62 can push the moving block 51 forward. Subsequently, when the moving block 51 can no longer move forward, as the moving plate 61 continues to move forward, the moving plate 61 compresses the connecting springs 62, and at the same time drives the connecting arm 63 to move forward inside the lower clearance groove 52 and the upper clearance groove 53. As the connecting arm 63 continues to move forward, the connecting arm 63 pushes the laser under test through the push block 64, thereby moving the laser under test from the top of the transposition disk 56 to the top of the heat dissipation base 21. When the moving plate 61 moves backward, the moving plate 61 can drive the compressed connecting springs 62 to reset. After the connecting springs 62 are reset, the connecting arm 63 is located at the last end inside the upper clearance groove 53. Subsequently, as the moving plate 61 continues to move backward, the moving plate 61 can drive the moving block 51 to move backward through the connecting arm 63.

[0040] Working principle:

[0041] In the initial state, the laser under test A is placed inside the U-shaped positioning frame 57 at the front end of the transposition disk 56 for positioning. Then, the motor C42 drives the reciprocating screw 43 to rotate clockwise. At this time, the reciprocating screw 43 drives the moving plate 61 guided by the guide rod C44 to move forward continuously. When the moving plate 61 moves forward, it pushes the moving block 51 forward through the two connecting springs 62. The moving block 51 drives the transposition disk 56 to move forward through the rotating cylinder 54. The transposition disk 56 drives the laser under test inside the front U-shaped positioning frame 57 to enter between the two clamping plates 26 until the front of the moving block 51 is in contact with the inner wall of the fixed frame 41. At this time, due to the obstruction of the inner wall of the fixed frame 41, the moving block 51 cannot move forward. At the same time, the front end of the transposition disk 56 is in contact with the rear end of the heat dissipation base 21.

[0042] As the moving plate 61 continues to move forward, it compresses the connecting spring 62, and simultaneously drives the connecting arm 63 to move forward inside the lower clearance groove 52 and the upper clearance groove 53. As the connecting arm 63 continues to move forward, it pushes the laser under test A through the pushing block 64, thereby moving the laser under test A from the top of the transposition disk 56 to the top of the heat dissipation base 21. Then the moving plate 61 moves to the front end of the reciprocating thread on the outside of the reciprocating screw 43. As the reciprocating screw 43 continues to rotate, the moving plate 61 moves backward to reset. During the reset process of the moving plate 61, the traction pushing mechanism 6 and the laser support assembly 5 reset one after another, and then the motor C42 is stopped.

[0043] Two electric push rods A25 drive two clamping plates 26 to move inward, thereby clamping and fixing the laser under test A. Then, the laser under test A is connected to the control system of the aiming device 28, motor A13 and motor B18, and the control system controls the drone to fly within the test area. Then, the aiming device 28 reconnoits and aims at the drone within the test area. The control system controls motor A13 and motor B18 to start according to the reconnaissance data of the aiming device 28, thereby causing the lower U-shaped frame 14 to rotate the laser under test A and the upper U-shaped frame 16 to rotate the laser under test A to adjust the orientation of the laser under test A. After the adjustment is completed, the control system starts the laser under test A, thereby causing the laser under test A to emit a high-power laser to ablate and destroy the drone. After the test is completed, the rotation adjustment component 1 is reset.

[0044] During the above test, the laser under test B is positioned inside the U-shaped positioning frame 57 at the rear end of the top of the transposition disk 56. After the test of the laser under test A is completed, the motor C42 drives the reciprocating screw 43 to rotate counterclockwise. At this time, the moving plate 61 pushes the moving block 51 forward again through the connecting spring 62, so that the transposition disk 56 is once again attached to the rear end of the heat dissipation base 21. Then the push block 64 is pushed forward again and then moved back to reset.

[0045] During the repositioning process of the push block 64, the electric push rod B32 pushes the push plate 33, which is guided by the guide rod B34, to move backward. This causes the push plate 33 to push the laser under test A to move to the inside of the U-shaped positioning frame 57 at the front end of the top of the transposition disk 56. As the moving plate 61 moves backward, the drive gear 55 meshes with the drive rack 46. When the moving plate 61 continues to move backward, the drive rack 46 drives the rotating cylinder 54 to rotate through the drive gear 55, which in turn causes the rotating cylinder 54 to rotate the transposition disk 56.

[0046] When the moving plate 61 moves to the last end of the reciprocating thread on the outer side of the reciprocating screw 43, the switching plate 56 rotates 180 degrees. At this time, the laser under test A and the laser under test B are switched. Subsequently, as the reciprocating screw 43 continues to rotate, the moving plate 61 pushes the moving block 51 forward again until the laser under test B enters between the two clamping plates 26 and moves to the top of the heat dissipation base 21. During this process, due to the limitation of the one-way bearing between the drive gear 55 and the rotating cylinder 54, the drive rack 46 cannot drive the rotating cylinder 54 to rotate. Then the moving plate 61 moves backward to reset, thereby resetting the moving plate 61 and the laser support assembly 5 one after the other. The motor C42 is stopped again, and the laser under test B is tested. During the test of the laser under test B, the laser under test A located at the rear end of the top of the switching plate 56 is removed and the laser under test C is repositioned.
