Technical Field

[0001] This invention relates to the field of target equipment technology, specifically to a target device for rocket guidance and testing. Background Technology

[0002] The target device for testing the guidance of fire extinguishing rockets is designed to perform performance tests on the guidance system of fire extinguishing rockets at different distances. This device should be able to simulate different fire source locations to test the guidance accuracy of fire extinguishing rockets under various environmental conditions.

[0003] According to Chinese Patent No. CN113267089B, a tactical target vehicle target training system includes: a target acquisition device, a tactical target vehicle, a training controller, and a training tablet computer. The target acquisition device is mounted on top of the tactical target vehicle. It automatically detects targets and generates target data, which is then sent to the training controller. The target acquisition device receives start / pause signals from the training controller. The tactical target vehicle automatically detects its position and generates position data, which is then sent to the training controller. The tactical target vehicle receives movement signals from the training controller. The training controller receives the target data from the target acquisition device and the position data from the tactical target vehicle, and forwards both to the training tablet computer. The training controller receives start / pause signals and movement signals from the training tablet computer, and forwards the start / pause signals to the target acquisition device and the movement signals to the tactical target vehicle. The training tablet computer receives the movement signals and position data forwarded by the training controller and sends start / pause signals and movement signals to the training controller.

[0004] The document proposes a tactical target vehicle target training system. After the position is adjusted, the orientation of the target needs to be adjusted to ensure the accuracy of the target. However, the orientation adjustment is not convenient enough. The target orientation can only be adjusted by turning the entire walking device, which is not convenient to use. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a target device for rocket guidance and detection, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a target device for rocket guidance and detection, comprising a base, a traveling mechanism mounted on the bottom of the base, and a target body disposed above the base. A steering mechanism for adjusting the orientation of the target body is provided between the target body and the base. The steering mechanism includes a rotating base and a connecting shaft. The rotating base is fixedly connected to the base, one end of the connecting shaft is rotatably connected to the rotating base, and the other end of the connecting shaft is fixedly connected to the target body, so that the target body can rotate horizontally to adjust its orientation.

[0007] Preferably, the connecting shaft includes a vertical shaft, a first inclined rod, a second inclined rod, a first vertical rod, and a second vertical rod. The vertical shaft is rotatably connected to the rotating base. The top of the vertical shaft is fixedly connected to the first inclined rod. The end of the first inclined rod away from the vertical shaft is fixedly connected to the first vertical rod. The top of the first vertical rod is fixedly connected to the second inclined rod. The top of the second inclined rod is fixedly connected to the second vertical rod. The top of the second vertical rod is fixedly connected to the target body. The axis of the second vertical rod coincides with the axis of the vertical shaft.

[0008] Preferably, the first vertical rod is positioned in the middle of the front of the target body, such that the orientation of the first vertical rod corresponds to the orientation of the target body.

[0009] Preferably, it also includes an adjustment mechanism for automatically adjusting the orientation of the target body. The adjustment mechanism includes a pull rope, a winding device, and a rotating ring. The rotating ring is rotatably connected to the first vertical rod. One end of the pull rope is fixedly connected to the rotating ring, and the other end of the pull rope is connected to the winding device. In use, the winding device is placed at the origin where the operator is located, and the pull rope is wound into the winding device. The walking mechanism is activated to drive the base to move to a suitable distance. During the movement of the walking mechanism, the pull rope gradually lengthens. At the same time, under the tension of the pull rope, the first vertical rod always faces the origin, so that the target body faces the origin.

[0010] Preferably, the winding device includes a fixed base, a vertical cylinder, a housing, a drive motor, a winding wheel, a rotating drum, an internal thread, a screw, an external thread, a pin, a groove, a limiting ring, and a slider. The top of the fixed base is fixedly connected to the vertical cylinder, the top of the vertical cylinder is fixedly connected to the housing, the top of the housing is fixedly connected to the drive motor, the housing contains a winding wheel, the output end of the drive motor is coaxially connected to the winding wheel, the winding wheel is fixedly connected to a pull rope, and the bottom of the winding wheel is fixedly connected to a rotating drum. The rotating drum rotatably engages with the inner wall of the rotating drum within the vertical cylinder, and an internal thread is formed on the inner wall of the rotating drum. The screw... The screw has an external thread that matches the internal thread. The screw is threaded into the drum. A pin is fixedly connected to the bottom end of the screw. A groove is provided on the screw. A limiting ring is located below the drum and is fixedly connected to the vertical cylinder. A slider is fixedly connected to the inner side of the limiting ring. The groove on the screw slides onto the slider, so that when the winding wheel releases the rope, the drum can rotate synchronously. The drum rotates, but the screw inside the drum cannot rotate due to the restriction of the slider on the limiting ring. This causes the screw to descend while the winding wheel rotates, so that the pin at the bottom end of the screw inserts into the ground at the origin.

[0011] Preferably, the bottom of the fixing base is fixedly connected to an anti-slip pad, and the anti-slip pad has anti-slip texture.

[0012] Preferably, the fixing base has a through hole corresponding to the insertion pin.

[0013] Preferably, the fixing base is hollow and the interior of the fixing base is filled with weight-adding sand.

[0014] This invention provides a target device for rocket guidance and detection. It has the following advantages: 1. The target device for rocket guidance and detection can easily adjust the orientation of the target as needed through the setting of the steering mechanism. The adjustment is very convenient. Through the setting of the adjustment mechanism, the target body can always be oriented towards the origin position by pulling the rope during the movement of the base.

[0015] 2. In use, the target device for rocket guidance and testing is operated by placing the winding device at the operator's origin point. Simultaneously, the pull rope is wound into the winding device. The traveling mechanism is then activated, driving the base to move to a suitable distance. During this movement, the pull rope gradually lengthens, and under the tension of the rope, the first vertical rod always faces the origin, ensuring the target body is also aligned with the origin. Once the target has been moved to the appropriate testing distance, the traveling mechanism is stopped. Simultaneously, as the pull rope lengthens, it drives the winding wheel to unload the rope. As the winding wheel rotates, the drum rotates synchronously. The screw inside the drum is limited by the slider on the limiting ring. The screw cannot rotate, causing it to descend as the winding wheel rotates. This allows the pin at the bottom of the screw to insert into the soil at the origin. This ensures that the target body always faces the origin while the pin automatically inserts into the soil, preventing the winding device from being pulled over and ensuring its effectiveness. During testing, the tester holds a launcher and fires a test fire extinguishing projectile at the target body, which is made of paper. After hitting the target body, the test projectile passes through it, activating the walking mechanism to return the base to the origin. Then, the drive mechanism is activated to wind up the rope, simultaneously resetting the screw and pulling the pin out of the soil, completing one test. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] This invention provides a target device for rocket guidance and detection, such as... Figure 1-7 As shown, the device includes a base 1, a walking mechanism 3 installed at the bottom of the base 1, and a target body 2 set above the base 1. A steering mechanism for adjusting the orientation of the target body 2 is provided between the target body 2 and the base 1. The steering mechanism includes a rotating seat 6 and a connecting shaft. The rotating seat 6 is fixedly connected to the base 1. One end of the connecting shaft is rotatably connected to the rotating seat 6, and the other end of the connecting shaft is fixedly connected to the target body 2, so that the target body 2 can rotate horizontally to adjust its orientation.

[0020] The steering mechanism allows for easy adjustment of the target's orientation as needed, making the adjustment very convenient.

[0021] In some embodiments, such as Figure 2-3 As shown, the connecting shaft includes a vertical shaft 7, a first inclined rod 8, a second inclined rod 10, a first vertical rod 9, and a second vertical rod 11. The vertical shaft 7 is rotatably connected to the rotating base 6. The top of the vertical shaft 7 is fixedly connected to the first inclined rod 8. The end of the first inclined rod 8 away from the vertical shaft 7 is fixedly connected to the first vertical rod 9. The top of the first vertical rod 9 is fixedly connected to the second inclined rod 10. The top of the second inclined rod 10 is fixedly connected to the second vertical rod 11. The top of the second vertical rod 11 is fixedly connected to the target body 2. The axis of the second vertical rod 11 coincides with the axis of the vertical shaft 7.

[0022] The first vertical rod 9 is positioned in the middle of the front of the target body 2, such that the orientation of the first vertical rod 9 corresponds to the orientation of the target body 2.

[0023] In some embodiments, such as Figure 1As shown, it also includes an adjustment mechanism for automatically adjusting the orientation of the target body 2. The adjustment mechanism includes a pull rope 5, a winding device 4, and a rotating ring 12. The rotating ring 12 is rotatably connected to the first vertical rod 9. One end of the pull rope 5 is fixedly connected to the rotating ring 12, and the other end of the pull rope 5 is connected to the winding device 4. In use, the winding device 4 is placed at the origin where the operator is located, and the pull rope 5 is wound into the winding device 4. The walking mechanism 3 is activated to drive the base 1 to move to a suitable distance. During the movement of the walking mechanism 3, the pull rope 5 gradually lengthens. At the same time, under the pulling force of the pull rope 5, the first vertical rod 9 always faces the origin, so that the target body 2 faces the origin.

[0024] By adjusting the mechanism, the target body 2 can always be oriented towards the origin position by pulling the rope 5 during the movement of the base 1.

[0025] In some embodiments, such as Figure 4-7 As shown, the winding device 4 includes a fixed base 13, a vertical cylinder 14, a housing 15, a drive motor 16, a winding wheel 17, a rotating drum 18, an internal thread 25, a screw 20, an external thread 21, a pin 22, a slide groove 23, a limiting ring 19, and a slider 24. The top of the fixed base 13 is fixedly connected to the vertical cylinder 14, the top of the vertical cylinder 14 is fixedly connected to the housing 15, the top of the housing 15 is fixedly connected to the drive motor 16, the winding wheel 17 is disposed inside the housing 15, the output end of the drive motor 16 is coaxially connected to the winding wheel 17, the winding wheel 17 is fixedly connected to the pull rope 5, and the bottom of the winding wheel 17 is fixedly connected to the rotating drum 18. The rotating drum 18 is rotatably fitted inside the vertical cylinder 14. An internal thread 25 is formed on the inner wall of the rotating drum 18, and the screw 20 is... The screw 20 is threaded with an external thread 21 that matches the internal thread 25. The screw 20 is threaded into the rotating drum 18. A pin 22 is fixedly connected to the bottom end of the screw 20. A groove 23 is provided on the screw 20. A limiting ring 19 is located below the rotating drum 18 and is fixedly connected to the vertical cylinder 14. A slider 24 is fixedly connected to the inner side of the limiting ring 19. The groove 23 on the screw 20 is slidably engaged with the slider 24, so that when the winding wheel 17 rotates to release the rope, the rotating drum 18 can rotate synchronously. The rotating drum 18 rotates, but the screw 20 inside the rotating drum 18 cannot rotate due to the restriction of the slider 24 on the limiting ring 19. This causes the screw 20 to descend while the winding wheel 17 rotates, so that the pin 22 at the bottom end of the screw 20 is inserted into the soil at the origin.

[0026] In use, the winding device 4 is placed at the operator's origin, and the pull rope 5 is wound into the winding device 4. The walking mechanism 3 is activated to drive the base 1 to move to a suitable distance. During the movement of the walking mechanism 3, the pull rope 5 gradually lengthens. Under the tension of the pull rope 5, the first vertical rod 9 always faces the origin, making the target body 2 face the origin. After moving to the appropriate test distance, the walking mechanism 3 is stopped. At the same time, as the pull rope 5 lengthens, it drives the winding wheel 17 to unwind and rotate. When the winding wheel 17 unwinds and rotates, the rotating drum 18 can rotate synchronously. While the rotating drum 18 rotates, the screw 20 inside the rotating drum 18 cannot rotate due to the restriction of the slider 24 on the limiting ring 19. This causes the screw 20 to descend while the winding wheel 17 rotates, allowing the pin 22 at the bottom of the screw 20 to insert into the soil at the origin. This ensures that the target body 2 always faces the origin, while the pin 22 automatically inserts into the soil, preventing the winding device 4 from being pulled down and ensuring the effectiveness of the test. During the test, the tester holds the launcher and fires a test fire extinguishing projectile at the target body 2. The target body 2 is a paper target. After hitting the target body 2, the test projectile passes through the target body 2, and the walking mechanism 3 is activated to control the base 1 to return to the origin. Then, the drive mechanism is activated to wind up the pull rope 5, which simultaneously drives the screw 20 to reset, causing the pin 22 to be pulled out of the soil, completing one test.

[0027] The bottom of the fixed base 13 is fixedly connected to an anti-slip pad, and the anti-slip pad has anti-slip texture.

[0028] The mounting base 13 has a through hole corresponding to the pin 22.

[0029] The fixing base 13 is hollow, and the interior of the fixing base 13 is filled with weight-adding sand.

[0030] Working principle: During use, the winding device 4 is placed at the operator's origin, and the pull rope 5 is wound into the winding device 4. The walking mechanism 3 is activated to drive the base 1 to move to a suitable distance. During the movement of the walking mechanism 3, the pull rope 5 gradually lengthens. Under the tension of the pull rope 5, the first vertical rod 9 always faces the origin, making the target body 2 face the origin. After moving to the appropriate test distance, the walking mechanism 3 is stopped. At the same time, as the pull rope 5 lengthens, it drives the winding wheel 17 to unwind and rotate. When the winding wheel 17 unwinds and rotates, the rotating drum 18 can rotate synchronously. While the rotating drum 18 rotates, the screw 20 inside the rotating drum 18 cannot move due to the restriction of the slider 24 on the limiting ring 19. The rotation causes the screw 20 to descend as the winding wheel 17 rotates, allowing the pin 22 at the bottom of the screw 20 to insert into the soil at the origin. This ensures that the target body 2 always faces the origin, while the pin 22 automatically inserts into the soil, preventing the winding device 4 from being pulled down and ensuring the effectiveness of the test. During the test, the tester holds the launcher and fires a test fire extinguishing projectile at the target body 2. The target body 2 is a paper target. After hitting the target body 2, the test projectile passes through the target body 2, and the walking mechanism 3 is activated to control the base 1 to return to the origin. Then, the drive mechanism is activated to wind up the pull rope 5, which simultaneously drives the screw 20 to reset, causing the pin 22 to be pulled out of the soil, completing one test.
