Description

Technical Field

[0001] The utility model relates to the field of aircrafts, in particular to an adjustable anti-aircraft device for low-altitude aircrafts. Background Art

[0002] An aircraft anti-aircraft device is a device for countering and preventing low-altitude operable aircrafts such as drones. It ensures the operation of aircrafts in a legal, safe and orderly environment through means such as detection, identification, interference, deception, control or destruction, and prevents them from being used for illegal activities or causing harm.

[0003] Currently, during the use of low-altitude aircraft anti-aircraft devices, the anti-aircraft device often needs to be placed on the ground first. After retrieval, Chinese Patent Publication No.: CN212776459U discloses an anti-aircraft device for unmanned aircrafts used in nuclear facility defense, including an anti-aircraft body. A support block is fixedly connected to the bottom end of the anti-aircraft body. A first disc is rotatably connected inside the support block. A stabilizing block is provided at the bottom end of the support block. A second disc is fixedly connected to the top of the stabilizing block. The second disc penetrates through the inside of the support block. By providing a first support rod at the bottom end of the stabilizing block and adding the first support rod and the sliding sleeve, when the fixing block can fit with the ground, the stability of the device is greatly increased, and at the same time, the fixing block can adapt to uneven ground. The diameter of the second chute is larger than the diameter of the sliding rod, so that when the fixing block fits with uneven ground, the sliding rod will not be stuck in the second chute. The addition of the stopper makes the sliding rod not slide out of the groove. The cross-sectional shape of the engaging groove is set as an arc, so that when the engaging rod disengages from the engaging groove, it is more labor-saving.

[0004] Although the above application document can ensure the fit with the ground to a certain extent on uneven ground, during actual use, when the ground is an inclined plane, it may cause the overall device to be in an inclined state, so the scanning range of the anti-aircraft device may deviate.

The shape of the mounting rod 41 is a cylinder. A sliding groove 42 is opened at the bottom end of the mounting rod 41. The shape of the sliding groove 42 is a cylinder. A sliding rod 43 is slidably connected to the inner wall of the sliding groove 42. There is a large frictional force between the sliding rod 43 and the sliding groove 42. Through the setting of the frictional force, it is ensured that the sliding rod 43 is not easily moved up and down without external force. The height of the sliding rod 43 fits the height of the sliding groove 42. A support plate 44 is fixedly connected to the bottom end of the sliding rod 43. A support rod 45 is hinged to the outer wall of the mounting rod 41. The shape of the support rod 45 is a cylinder.

[0037] Refer to Figure 3 - Figure 5 , an adjusting assembly 46 is provided inside the support rod 45. The adjusting assembly 46 includes a threaded groove 461. The threaded groove 461 is opened on the inner wall of the support rod 45. A moving groove 462 is opened on the inner wall of the support rod 45 below the threaded groove 461. The outermost diameter of the threaded groove 461 is smaller than the diameter of the moving groove 462. A threaded rod 463 is threadedly connected to the inner wall of the threaded groove 461. The outer wall of the threaded rod 463 fits the shape of the inner wall of the threaded groove 461. The bottom of the threaded rod 463 is rotatably connected to an extension rod 464. Through the rotatable connection method, it is ensured that the threaded rod 463 and the extension rod 464 can rotate relative to each other, so as to ensure that the threaded rod 463 can only drive the extension rod 464 to move during rotation, rather than causing the extension rod 464 to rotate with the rotation of the threaded rod 463. The outer wall of the extension rod 464 is slidably connected to the inner wall of the moving groove 462.

[0038] Refer to Figure 3 - Figure 5 , a control groove 465 is opened on the inner wall of the threaded rod 463.

The upper surface of the installation shell 471 is fixedly connected to the lower surface of the extension rod 464. A grounding block 472 is rotatably connected to the inner wall of the installation shell 471. The shape of the grounding block 472 is a rectangular parallelepiped, and a rotating shaft fixedly connected to the inner wall of the installation shell 471 is provided in the middle of the grounding block 472. A pressing plate 473 is rotatably connected to the outer wall of the grounding block 472. A magnet is provided inside the pressing plate 473, and a magnet is also provided on the inner wall of the grounding block 472. When the outer wall of the grounding block 472 fits with the pressing plate 473, the magnet inside the pressing plate 473 and the magnet inside the grounding block 472 just attract each other. Through the setting of the magnet, it is ensured that when the pressing plate 473 is not needed, the pressing plate 473 can fit with the outer wall of the grounding block 472 and will not be separated from each other under the action of gravity. A push-pull block 474 penetrates and is slidably connected to the inner wall of the installation shell 471. An insertion bar 475 is fixedly connected to the outer wall of the push-pull block 474. The shape of the insertion bar 475 is a cylinder, and the end of the insertion bar 475 is provided with a tip. A jack 476 is opened at one end of the grounding block 472 close to the push-pull block 474. The shape of the jack 476 is an annular shape formed by connecting multiple circles, and the diameters of the multiple small circles of the jack 476 fit with the diameter of the insertion bar 475. An air pressure chamber 477 is opened on the inner wall of the grounding block 472. The shape of the air pressure chamber 477 is a shape formed by connecting a rectangular parallelepiped groove above and multiple cylindrical grooves below. A moving bar 478 is piston-connected to the inner wall of the air pressure chamber 477. The diameter of the moving bar 478 fits with the diameter of the cylindrical groove of the air pressure chamber 477. A sliding plate 479 is piston-connected to the inner wall of the air pressure chamber 477.

[0040] Refer to Figure 6 - Figure 8 , a sliding groove 4710 is opened on the outer wall of the grounding block 472. The sliding groove 4710 can communicate the air pressure chamber 477 with the external air. A control block 4711 is piston-connected to the inner wall of the sliding groove 4710. The control block 4711 includes a long plate with a height longer than twice the length of the sliding groove 4710 and a rectangular parallelepiped protrusion with a height consistent with the height of the sliding plate 479. And the protrusion of the control block 4711 is arranged in the middle of the long plate. An insertion rod 4712 penetrates and is slidably connected to the inner wall of the control block 4711. An insertion opening 4713 is opened on the outer wall of the grounding block 472. The diameter of the insertion opening 4713 fits with the diameter of the insertion rod 4712, and the number of the insertion openings 4713 is multiple, and the multiple insertion openings 4713 are arranged in a linear array.

[0041] Working principle: When in use, the staff first pulls out the sliding rod 43, and temporarily places the device on the ground to be installed through the support plate 44. Then the staff pulls the support rod 45 outwards, and then pulls out the push-pull block 474, so that the push-pull block 474 drives the insertion bar 475 to move outwards, so as to leave the jack 476.

[0042] When the ground is flat, adjust the plane of the ground contact block 472 to be in contact with the ground. When the ground is uneven, adjust the ground contact block 472 until the moving bar 478 is in contact with the ground, and pull out the insertion rod 4712. After the insertion rod 4712 leaves the socket 4713, push the control block 4711, so that the control block 4711 drives the sliding plate 479 to move, so that the air pressure inside the air pressure chamber 477 increases, so that the moving bar 478 moves downward under the action of air pressure, so that the bottom end of the moving bar 478 is in contact with the ground.

[0043] After adjusting the position of the ground contact block 472, the staff pulls out the pressure plate 473 and places a heavy object above the pressure plate 473, so that the position of the ground contact block 472 is fixed.

[0044] After the ground contact block 472 is fixed, the staff moves the sliding rod 43 and the support plate 44 upward, stands between the two support rods 45, and checks the difference between the top of the liquid level in the observation frame 3 and the upper surface of the connection plate 2, and adjusts the length of the corresponding extension rod 464 according to the actual situation.

[0045] When adjusting the length of the extension rod 464, the staff rotates the knob 4611, so that the knob 4611 drives the rotating rod 469 and the second bevel gear 4610 to rotate, so that the second bevel gear 4610 drives the first bevel gear 468 to rotate, so that the rotating rod 467 rotates.

[0046] When the rotating rod 467 rotates, the rotating rod 467 drives the protruding block 466 to rotate, so that the protruding block 466 squeezes the inner wall of the control groove 465 during rotation, so that the threaded rod 463 rotates, so that the threaded rod 463 drives the extension rod 464 to move during rotation, so that the length of the extension rod 464 inside the moving groove 462 changes, so that the total length of the extension rod 464 and the support rod 45 changes.

[0047] After the change is completed, the staff observes the parallelism between the liquid level and the upper surface of the connection plate 2 again and makes adjustments again according to the situation until the liquid level is completely flush with the upper surface of the connection plate 2. At this time, it can be ensured that the anti-countermeasure device body 1 is in a horizontal state, so as to ensure that there are no dead corners when using the equipment.

[0048] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
