Description

Technical Field

[0001] This utility model relates to the field of runway foreign object detection, specifically a tower-type runway foreign object detection device. Background Technology

[0002] In the field of aviation safety, real-time monitoring of foreign objects on runways (FOD) is a key link in ensuring the safety of flight take-off and landing. Existing FOD detection systems mostly rely on fixed-installation optical monitoring equipment (such as high-definition cameras) in conjunction with radar. However, in practical applications, their monitoring flexibility and reliability still have significant shortcomings, making it difficult to meet the accurate detection needs of complex airport scenarios.

[0003] Traditional optical monitoring equipment is mostly fixed at a specific height on towers or fences, with a fixed shooting angle and monitoring radius. When the track has curves, changes in slope, or surrounding obstacles (such as light towers or green belts), blind spots are easily formed. For example, backlit areas at both ends of the track or low objects near the ground (such as gravel or metal fragments) often cannot be clearly captured due to the fixed equipment height, resulting in a missed detection rate of over 90%. Some adjustable optical monitoring equipment can only achieve fine-tuning of the angle in one direction and cannot simultaneously accommodate height adjustment and horizontal extension.

[0004] The existing adjustment structure lacks a stable self-locking function. After height adjustment, it relies solely on the braking effect of the drive motor to maintain the position. When encountering strong winds or equipment vibration, it is prone to slow descent or displacement, causing the monitoring screen to deviate. When operators discover suspected foreign objects in the background, they need to repeatedly switch the control interface to manually calibrate the equipment position. Furthermore, it is impossible to obtain the current height and extension distance of the equipment in real time, resulting in excessively long time for accurate positioning and affecting the efficiency of emergency response.

[0005] Therefore, there is an urgent need for a tower-type runway foreign object detection device that integrates height and telescopic distance adjustment functions and has a reliable self-locking structure. This device enables multi-dimensional flexible movement of the optical monitoring equipment through remote control, and with immediate locking after adjustment, ensures that the equipment is stably aligned with the monitoring target in complex environments. This improves the accuracy and response speed of runway foreign object detection, providing more reliable technical support for aviation safety. Utility Model Content

[0006] The purpose of this invention is to provide a tower-type runway foreign object detection device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a tower-type runway foreign object detection device, comprising a tower and a fence platform welded to the top of the tower. A millimeter-wave detection radar is fixedly installed on the top of the fence platform via three support columns. A support frame is fixedly installed on the top of the fence platform near a corner. A sliding frame is slidably mounted on the inner side of the support frame along the vertical direction. A driving component for driving the camera displacement is installed on the top of the sliding frame via an extension frame. A locking component is configured between the support frame and the sliding frame. The locking component can lock and fix the sliding frame when it stops moving to prevent it from falling.

[0008] Preferably, the driving component includes: a first motor, a first lead screw, a second motor, a second lead screw, and a moving block. The first motor is fixedly mounted on the inner side of the support frame near the bottom, with its output shaft facing upward and connected to the first lead screw. The first lead screw passes through the bottom of the sliding frame vertically and is threadedly connected to the sliding frame, enabling the sliding frame to move up and down along the support frame. The second lead screw passes through the inner side of the sliding frame horizontally, with one end connected to the second motor fixedly mounted on the sliding frame. The moving block is threaded onto the outer side of the second lead screw and slides in cooperation with the inner side of the sliding frame. The camera is fixedly mounted on the top of the moving block by bolts and can move horizontally under the drive of the second lead screw.

[0009] Preferably, the locking component includes: a movable cavity, a sliding plate, a locking groove, and a spring. The movable cavity is located on both sides of the bottom of the sliding frame. The sliding plate is slidably assembled in the movable cavity in a horizontal direction. A locking block is fixedly connected to one side of the sliding plate. There are multiple locking grooves evenly distributed on both sides inside the support frame, which can be engaged with the locking blocks. The two ends of the spring are fixedly connected to the sliding plate and the inner sidewall of the movable cavity, respectively, and can drive the locking block to push towards the locking groove.

[0010] Preferably, the locking component further includes an electric push rod and a limiting plate. The electric push rod is fixedly installed on the side of the movable cavity away from the locking block. Its output end passes through the sliding plate and can drive the sliding plate to compress the spring through the limiting plate, so that the locking block disengages from the locking groove.

[0011] Preferably, the movable block extends from both sides with limiting portions, and the extension frame has a corresponding guide groove adapted to the limiting portion, and the limiting portion is slidably fitted into the guide groove.

[0012] Preferably, the extension frame has multiple drainage holes at the bottom near the two side edges.

[0013] Preferably, the outer side of the second motor is provided with a protective cover, which is fixed to the sliding frame by bolts, and the cover body is provided with a clearance hole corresponding to the position of the output shaft of the second motor.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The tower supports the millimeter-wave radar and camera via a fence, enabling the millimeter-wave radar and camera to perform dual monitoring of foreign objects on the runway. The sliding frame slides up and down within the support frame via a drive mechanism and is locked in place by a locking mechanism to prevent it from falling. The camera on top of the extension frame is moved horizontally by the drive mechanism. If the camera captures an unclear image, the camera's height and horizontal position can be adjusted to ensure accurate and high-definition imaging of foreign objects on the runway.

[0016] 2. The spring can compress and push the sliding plate. The cross-section of the locking block and the locking groove are both right-angled triangles. The locking block and the inclined surface of the locking groove are in contact, so that the sliding frame can move the locking block upward. The locking groove compresses and pushes the spring on one side of the sliding plate through the locking block. The electric push rod drives the limiting plate to move. Therefore, the limiting plate pushes the sliding plate and causes the locking block to disengage from the locking groove, which improves the convenience of unlocking the sliding frame and the stability of locking the sliding frame.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please refer to Figure 1-5 As shown, this utility model provides a tower-type runway foreign object detection device, including a tower 1 and a fence platform 2 welded to the top of the tower 1. A millimeter-wave detection radar 4 is fixedly installed on the top of the fence platform 2 by three support columns 3. A support frame 5 is fixedly installed on the top of the fence platform 2 near the corner. A sliding frame 6 is slidably assembled on the inner side of the support frame 5 along the vertical direction. A driving component for driving the displacement of a camera 8 is installed on the top of the sliding frame 6 by an extension frame 7. A locking component is configured between the support frame 5 and the sliding frame 6. The locking component can be locked in place when the sliding frame 6 stops moving to prevent it from falling.

[0026] Additionally, tower 1 supports millimeter-wave radar 4 and camera 8 via fence platform 2, enabling dual monitoring of foreign objects on the runway by millimeter-wave radar 4 and camera 8. The sliding frame 6 is driven by a drive unit to slide up and down within the support frame 5, and is locked and fixed by a locking unit to prevent it from falling. The drive unit pushes the camera 8 on the top of the extension frame 7 to move horizontally. If the camera 8 captures an unclear image, its height and horizontal position can be adjusted to allow the camera 8 to accurately and clearly capture foreign objects on the runway.

[0027] Specifically, the driving components include: a first motor 9, a first lead screw 10, a second motor 11, a second lead screw 12, and a moving block 13. The first motor 9 is fixedly mounted inside the support frame 5 near the bottom, with its output shaft facing upward and connected to the first lead screw 10. The first lead screw 10 passes vertically through the bottom of the sliding frame 6 and is threadedly connected to the sliding frame 6, driving the sliding frame 6 to rise and fall along the support frame 5. The second lead screw 12 passes horizontally through the inside of the sliding frame 6, with one end connected to the second motor 11 fixedly mounted on the sliding frame 6. The moving block 13 is threadedly fitted onto the outside of the second lead screw 12 and is connected to the sliding frame 6. The moving frame 6 slides inside, and the camera 8 is fixed to the top of the moving block 13 by bolts. It can move horizontally under the drive of the second lead screw 12. Limiting parts 21 extend from both sides of the moving block 13. The extension frame 7 is opened with guide grooves 22 that are adapted to the limiting parts 21. The limiting parts 21 are slidably embedded in the guide grooves 22. The second motor 11 is covered with a protective cover 24. The protective cover 24 is fixed to the sliding frame 6 by bolts. The cover body is opened with a clearance hole corresponding to the position of the output shaft of the second motor 11. Multiple water leakage holes 23 are opened at the bottom of the extension frame 7 near the two side edges.

[0028] The controller allows for remote control of the first motor 9, the second motor 11, and the electric push rod 19. This is a relatively mature technology and will not be elaborated upon here. The first motor 9 can drive the first lead screw 10 to push the sliding frame 6 to move up and down through a threaded connection. The second motor 11 can drive the moving block 13 to change its horizontal position within the extension frame 7 through the second lead screw 12. The protective cover 24 on the outside of the second motor 11 can protect it from rain and snow and prevent it from being corroded by rainwater.

[0029] Furthermore, when the moving block 13 moves, it slides within the long guide groove 22 of its limiting part 21. The limiting part 21 guides the moving block 13. The multiple drainage holes 23 at the bottom of the extension frame 7 facilitate the downward flow of rainwater. The first lead screw 10 and the second lead screw 12 are both made of rust-proof aluminum alloy.

[0030] More specifically, the locking components include: a movable cavity 14, a sliding plate 15, a locking groove 16, and a spring 17. The movable cavity 14 is located on both sides of the bottom of the sliding frame 6. The sliding plate 15 is slidably mounted in the movable cavity 14 in the horizontal direction. A locking block 18 is fixedly connected to one side of the sliding plate 15. There are multiple locking grooves 16, which are evenly distributed on both sides inside the support frame 5 and can be engaged with the locking blocks 18. The two ends of the spring 17 are fixedly connected to the sliding plate 15 and the inner side wall of the movable cavity 14, respectively, and can drive the locking block 18 to push towards the locking groove 16. The locking components also include an electric push rod 19 and a limiting plate 20. The electric push rod 19 is fixedly mounted on the side of the movable cavity 14 away from the locking block 18. Its output end passes through the sliding plate 15 and can drive the sliding plate 15 to compress the spring 17 through the limiting plate 20, so that the locking block 18 is disengaged from the locking groove 16.

[0031] Furthermore, the spring 17 can press and push the sliding plate 15. The locking block 18 and the locking groove 16 both have right-angled triangular cross sections. The locking block 18 and the locking groove 16 are in contact with the inclined surfaces, so that the sliding frame 6 can move the locking block 18 upward. The locking groove 16 presses and pushes the spring 17 on one side of the sliding plate 15 through the locking block 18. The electric push rod 19 drives the limiting plate 20 to move. Therefore, the limiting plate 20 pushes the sliding plate 15 and causes the locking block 18 to disengage from the locking groove 16, improving the convenience of unlocking the sliding frame 6 and the stability of locking the sliding frame 6.

[0032] Working principle: First, start the first motor 9 to drive the first lead screw 10 to push the sliding frame 6 upward through the threaded connection. Then start the second motor 11 to drive the moving block 13 to change its horizontal position within the extension frame 7 through the second lead screw 12. The sliding frame 6 drives the locking block 18 to move upward. The locking groove 16 presses and pushes the spring 17 on one side of the sliding plate 15 through the locking block 18. Then the spring 17 presses and pushes the sliding plate 15, so that the locking block 18 on one side of the sliding plate 15 is embedded in the locking groove 16 to lock the sliding frame 6 to prevent it from falling.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
