Technical Field

[0001] This application relates to the field of meteorological monitoring equipment technology, and in particular to a low-altitude wind shear detection device based on wind profiler radar. Background Technology

[0002] Low-level wind shear is a sudden change in wind direction and speed occurring at altitudes of several thousand meters at low altitudes, posing a serious threat to aviation safety. During takeoff and landing, low-level wind shear can cause sudden changes in airspeed and loss of attitude control, leading to flight accidents. Therefore, timely and accurate detection of low-level wind shear is crucial. Wind profiler radar, as an advanced meteorological detection device, can utilize the principle of electromagnetic wave scattering by atmospheric turbulence to achieve vertical detection of wind fields at different altitudes.

[0003] However, existing low-altitude wind shear detection devices based on wind profiler radar still have some problems. On the one hand, the structural stability of some devices is poor, making it difficult to guarantee normal operation and measurement accuracy under complex weather conditions, such as strong winds and heavy rain. On the other hand, the height adjustment function of the detection device is not flexible enough, failing to quickly and accurately adjust the detection height according to actual needs, thus affecting the detection effect of wind shear at different altitude levels. In addition, existing devices also have shortcomings in data recording and presentation methods; data recording is not intuitive or continuous, hindering staff from timely analyzing and judging wind shear conditions, thereby affecting aviation safety decisions.

[0027] Reference Figure 1 , Figure 2 , Figure 4One embodiment shown is as follows: The entire detection device uses a base 1 as its basic support component, which provides an installation platform for other mechanisms. Adjustable horizontal support legs 2 are connected to the bottom of the base 1 to ensure stable placement of the device on different terrains. A rotating detection mechanism 3 is mounted on the upper surface of the base 1. A wind-receiving rotating component 4 cooperates with a transmission conversion component 5. A wind cup assembly 6, as a key component of the wind-receiving rotating component 4, senses wind force and generates rotation. A height adjustment mechanism 7 is connected at one end to the base 1 and at the other end to the rotating detection mechanism 3, serving to adjust the height between the two. A recording pen 10 in the data recording mechanism 8 is movably connected to the transmission conversion component 5 via a transmission component, and recording paper 9 is wound around the data recording area corresponding to the recording pen 10. In this embodiment, the support assembly 2 can be adjusted to keep the base 1 in a horizontal state to ensure the accuracy of the detection; the wind cup assembly 6 senses the wind force and drives the wind-receiving rotating component 4 to rotate, and the transmission conversion component 5 converts the rotation into a specific motion; the height adjustment mechanism 7 can change the height of the rotating detection mechanism 3 according to actual needs to adapt to different detection scenarios; the transmission conversion component 5 converts the rotation of the wind cup assembly 6 into the up and down movement of the recording pen 10, so that the recording pen 10 records the wind shear data on the recording paper 9.

[0028] The implementation principle of the above embodiment is as follows: the base 1 is leveled by the support assembly 2, providing a foundation for the stable operation of the entire device; the wind cup group 6 in the rotating detection mechanism 3 rotates under the action of wind force, driving the wind-receiving rotating component 4, and the transmission conversion component 5 converts its rotation into a motion suitable for driving the recording pen 10; the height adjustment mechanism 7 adjusts the height of the rotating detection mechanism 3 according to actual needs, so that the detection device can adapt to different environments; in the data recording mechanism 8, the transmission conversion component 5 drives the recording pen 10 to move on the recording paper 9, thereby realizing the recording of wind shear data, and the various mechanisms work together to complete the detection and recording of low-altitude wind shear.

[0029] Reference Figure 1 , Figure 3 One embodiment shown is as follows: the support assembly 2, a key component at the bottom of the base 1, has multiple support sleeves 11 fixedly connected to the base 1 by welding. Specifically, the support sleeves 11 are welded to the four corners of the base 1. The welding connection allows the support sleeves 11 to be tightly integrated with the base 1, forming a stable overall structure, effectively enhancing the support strength of the bottom of the device and enabling it to withstand various external forces during operation. Each support sleeve 11 is internally connected to an adjusting leg 12 via a threaded engagement. The adjusting leg 12 is designed as a screw structure. This threaded connection method is based on the principle of screw transmission. By manually rotating the adjusting leg 12, the up-and-down movement of the adjusting leg 12 within the support sleeve 11 can be precisely controlled.

[0030] In this embodiment, the welded connection between the support sleeve 11 and the base 1 ensures the stability of the support assembly 2 within the device, providing a reliable support foundation. The threaded connection between the adjustable support 12 and the support sleeve 11 provides flexibility for leveling the device. When the device is placed on uneven ground, the length of the adjustable support 12 extending beyond the support sleeve 11 can be changed by rotating it to fine-tune the levelness of the base 1, ensuring that the base 1 is level. This design effectively avoids deviations in the detection data caused by the tilt of the base 1, greatly improving the accuracy and reliability of the detection results and ensuring stable operation of the device under various complex terrain conditions.

[0031] The implementation principle of the above embodiment is as follows: When the detection device needs to be installed, the device is first placed in a predetermined position, and then the levelness of the base 1 is observed. If the base 1 is not level, the adjusting feet 12 inside each foot sleeve 11 are rotated according to the tilt direction and degree of the base 1. Rotating the adjusting foot 12 clockwise moves it downward within the foot sleeve 11, increasing the support height on that side; rotating the adjusting foot 12 counterclockwise moves it upward, decreasing the support height on that side. By repeatedly adjusting the position of each adjusting foot 12, the levelness of the base 1 is continuously calibrated until the base 1 reaches a level state, completing the stable installation of the device and creating favorable conditions for subsequent accurate wind shear detection.

[0032] Reference Figure 1 , Figure 5 One embodiment shown is as follows: In the wind-receiving rotating component 4, the wind cup assembly 6 consists of a wind cup holder 13 and multiple spoon-shaped wind cups 14. The multiple spoon-shaped wind cups 14 are fixed to the periphery of the wind cup holder 13 by welding, bolting, or bonding. This fixed connection method ensures a firm connection between the spoon-shaped wind cups 14 and the wind cup holder 13, preventing them from easily loosening or falling off under external wind force. The unique spoon-shaped design of the spoon-shaped wind cups 14 provides a larger force-bearing area when facing the wind, enabling them to more efficiently capture wind force and convert it into their own rotational torque. The wind cup holder 13, as the supporting carrier of the spoon-shaped wind cups 14, provides a stable installation base for the spoon-shaped wind cups 14, ensuring that the multiple spoon-shaped wind cups 14 are evenly distributed on the same circumferential plane. This allows the wind cup assembly 6 to maintain balance and stability during rotation, accurately reflecting changes in the magnitude and direction of the wind force.

[0033] In this embodiment, the fixed connection between the spoon-shaped wind cup 14 and the wind cup holder 13 makes the wind cup assembly 6 a cooperating whole. When there is wind, the spoon-shaped wind cup 14 rotates under the force of the wind. Due to their fixed connection with the wind cup holder 13, they drive the wind cup holder 13 to rotate as well, converting changes in the external wind force into changes in the rotation angle and speed of the wind cup holder 13. This converts the wind force signal into a mechanical rotation signal that can be used by the subsequent transmission conversion component 5. This structural design significantly improves the response sensitivity and detection accuracy of the wind cup assembly 6 to changes in wind force, ensuring that the detection device can capture subtle changes in low-altitude wind shear in a timely and accurate manner, providing reliable raw data input for wind shear detection.

[0034] The implementation principle of the above embodiment is as follows: When wind occurs, the wind acts on the arc-shaped surface of the spoon-shaped wind cup 14. Due to the special shape of the spoon-shaped wind cup 14, the force exerted by the wind on it is decomposed into a torque that causes the spoon-shaped wind cup 14 to rotate around the central axis of the wind cup holder 13. Multiple spoon-shaped wind cups 14 are simultaneously subjected to wind force, jointly driving the wind cup holder 13 to rotate around the central axis, converting the changes in the magnitude and direction of the wind force into changes in the rotational state of the wind cup holder 13, that is, changes in the rotation angle and speed. The rotation of the wind cup holder 13 serves as the initial input signal of the rotation detection mechanism 3, which is transmitted to the subsequent transmission conversion component 5. The transmission conversion component 5 further converts this rotation signal into the up-and-down movement of the recording pen 10, thereby recording data information related to wind shear on the recording paper 9, realizing the detection and data recording of low-altitude wind shear phenomena.

[0035] Reference Figure 3 , Figure 4 One embodiment shown is as follows: The height adjustment mechanism 7 is located between the base 1 and the rotation detection mechanism 3, serving to connect and adjust the height. The rotating sleeve 15 is rotatably mounted on the base 1 via rotating connecting components such as bearings. This rotating connection allows the rotating sleeve 15 to rotate flexibly relative to the base 1, while ensuring the smoothness and stability of the rotation process. The rotating sleeve 15 is connected to the sliding cylinder 16 via a sliding fit. The inner walls of both are machined with high precision, ensuring that the sliding cylinder 16 can slide smoothly up and down along the axial direction within the rotating sleeve 15 without any shaking or jamming during the sliding process. The top of the sliding cylinder 16 is fixedly connected to the wind cup holder 13. Inside the sliding cylinder 16, one end of the return spring 17 is connected to the inner wall of the sliding cylinder 16 by welding, bonding, or other fixing methods, and the other end is also fixedly connected to the inner wall of the rotating sleeve 15. The return spring 17 is in a compressed state in the initial state, providing an upward elastic force to the sliding cylinder 16.

[0036] In this embodiment, the rotatable connection between the rotating sleeve 15 and the base 1 allows the rotating detection mechanism 3 to maintain a relatively flexible posture during height adjustment, adapting to different installation and testing requirements. The sliding connection between the sliding cylinder 16 and the rotating sleeve 15 provides a motion basis for the height adjustment of the rotating detection mechanism 3, allowing the sliding cylinder 16 to move up and down within the rotating sleeve 15, thereby changing the height of the rotating detection mechanism 3. The reset spring 17 not only acts as a buffer and reset mechanism during height adjustment but also, to a certain extent, offsets part of the weight of the rotating detection mechanism 3, reducing resistance during adjustment and making height adjustment easier and more convenient. When it is necessary to raise the rotating detection mechanism 3, an external force is applied to push the sliding cylinder 16 upward against the elastic force of the reset spring 17. When the external force is removed, the elastic force of the reset spring 17 will cause the sliding cylinder 16 to automatically reset or remain stably at the set height position, ensuring that the device works stably at the adjusted height.

[0037] The implementation principle of the above embodiment is as follows: When it is necessary to adjust the height of the rotating detection mechanism 3, an upward external force is applied to the sliding cylinder 16. Under the action of this external force, the sliding cylinder 16 overcomes the elastic force of the reset spring 17 and slides upward within the rotating sleeve 15, thereby driving the rotating detection mechanism 3 to rise and increasing the detection height of the detection device. When the required detection height is reached, the applied external force is removed. At this time, the reset spring 17, due to its own elastic restoring force, will generate a downward pulling force on the sliding cylinder 16, stabilizing the sliding cylinder 16 at the current height position and keeping the height of the rotating detection mechanism 3 unchanged. If it is necessary to lower the height of the rotating detection mechanism 3, the elastic force of the reset spring 17 can be released in a certain way. Under the combined action of the weight of the rotating detection mechanism 3 and the elastic force of the reset spring 17, the sliding cylinder 16 slides downward, thereby lowering the detection height. In this way, the height of the rotating detection mechanism 3 can be flexibly and conveniently adjusted to meet different detection environments and actual needs.

[0038] Reference Figure 1 , Figure 4 , Figure 5One embodiment shown is as follows: In the height adjustment mechanism 7, a connecting pipe 18 at the bottom of the rotating sleeve 15 is connected to the interior of the sliding cylinder 16, forming a gas flow channel. The connecting pipe 18 and the rotating sleeve 15 are rotatably connected by components such as bearings and rotary joints. This connection method ensures that the connecting pipe 18 can be relatively stably fixed on the base 1 when the rotating sleeve 15 rotates, without affecting the normal flow of gas in the pipe. At the end of the connecting pipe 18 away from the rotating sleeve 15, a press-type inflatable airbag 19 is fixedly connected by a sealing joint or other means to ensure good sealing at the connection point and prevent gas leakage. A one-way valve 20 is installed inside the connecting pipe 18 to ensure that gas can only flow into the connecting pipe 18 from the side of the inflatable airbag 19, preventing reverse flow of gas, thereby ensuring that gas can be effectively accumulated in the connecting pipe 18 and the sliding cylinder 16. The exhaust pipe 21 is located inside the connecting pipe 18 and above the one-way valve 20. The valve 22 is installed on the exhaust pipe 21. By controlling the opening and closing of the valve 22, the on / off control of the exhaust pipe 21 is realized, thereby controlling the discharge of gas.

[0039] In this embodiment, the rotatable connection between the connecting pipe 18 and the rotating sleeve 15 ensures that the rotation of the rotating sleeve 15 does not interfere with the flow of gas during the operation of the height adjustment mechanism 7, thus guaranteeing the normal operation of the height adjustment function. The connection between the inflatable airbag 19 and the connecting pipe 18 provides a convenient air source for inflating the connecting pipe 18. By pressing the inflatable airbag 19, gas can be quickly inflated into the connecting pipe 18 and the sliding cylinder 16, pushing the sliding cylinder 16 upward and raising the rotation detection mechanism 3. The one-way valve 20 ensures that the gas can only flow in one direction, preventing the backflow of the inflated gas and ensuring that the gas can effectively accumulate and generate sufficient pressure to push the sliding cylinder 16. The cooperation of the exhaust pipe 21 and the valve 22 allows the gas in the connecting pipe 18 and the sliding cylinder 16 to be discharged in a timely manner as needed, causing the sliding cylinder 16 to move downward under the action of the reset spring 17, thus lowering the rotation detection mechanism 3. Through the cooperation of these components, the height of the rotating detection mechanism 3 can be precisely and conveniently adjusted, meeting the diverse needs for detection height in different detection scenarios.

[0040] The implementation principle of the above embodiment is as follows: When it is necessary to raise the rotating detection mechanism 3, the inflatable airbag 19 is pressed. Under pressure, gas enters the connecting pipe 18 through the one-way valve 20. Due to the one-way conduction characteristic of the one-way valve 20, the gas can only flow in one direction and will not flow back. As the inflatable airbag 19 is continuously pressed, gas continuously fills the connecting pipe 18 and the sliding cylinder 16, causing the air pressure in the pipe and the sliding cylinder 16 to gradually increase. The gas pressure pushes the sliding cylinder 16 to slide upward against the elastic force of the reset spring 17, thereby driving the rotating detection mechanism 3 to rise. When the required height is reached, the inflatable airbag 19 is stopped, and the one-way valve 20 prevents the gas from flowing back, keeping the sliding cylinder 16 at the current height position. If it is necessary to lower the height of the rotating detection mechanism 3, the valve 22 on the exhaust pipe 21 is opened, and the gas in the connecting pipe 18 and the sliding cylinder 16 is discharged through the exhaust pipe 21. The air pressure decreases, and under the combined action of the elastic force of the reset spring 17 and the weight of the rotating detection mechanism 3 itself, the sliding cylinder 16 slides downward, realizing the reduction of the detection height. By controlling the pressing of the inflatable airbag 19 and the opening and closing of the exhaust valve 22, flexible and precise adjustment of the height of the rotating detection mechanism 3 is achieved.

[0041] Reference Figure 1 , Figure 5 , Figure 6 One embodiment is shown as follows: In the transmission conversion component 5, the fixed bushing 23 is fixedly connected to the bottom of the rotating sleeve 15 by welding, so that the fixed bushing 23 can rotate synchronously with the rotating sleeve 15. A positioning cylinder 24 with vertical axial orientation is fixedly installed on the base 1 by bolt connection, ensuring that the positioning cylinder 24 is stable and vertically positioned. The fixed bushing 23 is fitted onto the outside of the positioning cylinder 24, with a small gap between them, allowing the fixed bushing 23 to rotate flexibly relative to the positioning cylinder 24. The connecting pipe 18 is fixed to the inside of the positioning cylinder 24 by welding, ensuring the stability of gas flow without affecting the rotation of the fixed bushing 23. A hinge rod 25 is hinged to the periphery of the fixed bushing 23 via a hinge shaft, allowing the hinge rod 25 to swing freely around the hinge shaft. A movable bushing 26 is hinged to the bottom of the positioning cylinder 24 via a hinge seat, allowing the movable bushing 26 to move axially up and down at the bottom of the positioning cylinder 24. A connecting rod 27 is hinged to the movable bushing 26 via another hinge shaft. The other end of the connecting rod 27 is hinged to the hinge rod 25 via a hinge shaft. This multi-hinged structure allows for more flexible motion transmission between components. A gravity ball 28 is threaded onto the free end of the hinge rod 25, allowing the hinge rod 25 to remain drooping when there is no external force interference. A sliding sleeve 29 is welded to the bottom of the movable bushing 26. The sliding sleeve 29 and the positioning cylinder 24 are connected by a guide rail-slider sliding connection structure, allowing the sliding sleeve 29 to slide smoothly up and down on the positioning cylinder 24.

[0042] In this embodiment, the welding and fixing of the fixed bushing 23 and the rotating sleeve 15 ensures that the rotation of the rotating sleeve 15 can be reliably transmitted to the fixed bushing 23; the fitting of the fixed bushing 23 and the positioning cylinder 24 provides both support and enables relative rotation; the fixed connection between the connecting pipe 18 and the positioning cylinder 24 ensures the gas flow function of the height adjustment mechanism 7; the hinged and sliding connections between the hinge rod 25, the connecting rod 27, the movable bushing 26, and the sliding sleeve 29 constitute a transmission system that converts rotation into linear motion. The presence of the gravity ball 28 ensures the initial stability of the hinge rod 25, while the guide rail-slider structure makes the movement of the sliding sleeve 29 precise and stable.

[0043] The implementation principle of the above embodiment is as follows: When the wind cup assembly 6 drives the rotating sleeve 15 to rotate, the fixed bushing 23 fixedly connected to it rotates accordingly. During the rotation of the fixed bushing 23, the hinge rod 25 remains drooping under the action of the gravity ball 28. As the fixed bushing 23 rotates, the hinge rod 25 swings in a circle around the hinge point. The swing of the hinge rod 25 is transmitted to the movable bushing 26 through the connecting rod 27. Since the movable bushing 26 is hinged to the bottom of the positioning cylinder 24 and can move up and down, the pulling of the connecting rod 27 causes the movable bushing 26 to move up and down on the positioning cylinder 24. The sliding sleeve 29 at the bottom of the movable bushing 26 is connected to the movable bushing 26, thereby driving the sliding sleeve 29 to slide up and down synchronously on the guide rail of the positioning cylinder 24. Finally, the rotational motion of the wind cup assembly 6 is accurately converted into the vertical linear motion of the sliding sleeve 29, providing power transmission for data recording.

[0044] Reference Figure 1 , Figure 5 , Figure 6 One embodiment is shown as follows: A rotatable drive roller 30 and a driven roller 31 are bolted to the upper surface of the base 1. Both ends of the drive roller 30 and driven roller 31 are connected to the base 1 via bearings, ensuring flexible rotation. Recording paper 9 is wound around the outer sides of the drive roller 30 and driven roller 31 to form a data recording carrier. One end of a recording pen 10 is bolted to a sliding sleeve 29, while the other end remains in contact with the recording paper 9 with moderate pressure, ensuring clear marks without excessive pressure affecting the paper's movement. A drive motor 32 is fixedly mounted on the base 1 via a motor bracket. The output shaft of the drive motor 32 is rigidly connected to the drive roller 30 via a coupling, ensuring reliable power transmission. The drive motor 32 is a servo motor, capable of precisely controlling speed and direction to meet the recording requirements of wind shear data.

[0045] In this embodiment, the bolted connection between the drive roller 30 and the driven roller 31 and the base 1 ensures the stability of their installation. The bearing arrangement allows for smooth rotation of both rollers, providing support and guidance for the movement of the recording paper 9. The recording paper 9 is wound around the drive roller 30 and the driven roller 31 to form a continuous recording plane. The bolted connection between the recording pen 10 and the sliding sleeve 29 ensures that the recording pen 10 can move synchronously with the sliding sleeve 29. The drive motor 32 is connected to the coupling of the drive roller 30, realizing efficient power transmission, enabling the drive roller 30 to rotate at a set speed, driving the recording paper 9 to move at a uniform speed.

[0046] The implementation principle of the above embodiment is as follows: When the sliding sleeve 29 in the transmission conversion component 5 moves up and down on the positioning cylinder 24, the recording pen 10, which is fixedly connected to it, moves up and down synchronously. At the same time, the drive motor 32 starts and drives the active roller 30 to rotate through the coupling. The rotation of the active roller 30 drives the recording paper 9 to move at a constant speed between the active roller 30 and the driven roller 31 through friction. During the up and down movement, the recording pen 10 leaves a track on the uniformly moving recording paper 9, thereby recording the wind shear data reflected by the rotation of the wind cup assembly 6 in a visual form. By precisely controlling the speed of the drive motor 32, the moving speed of the recording paper 9 can be adjusted according to actual needs to ensure that the recorded data can accurately reflect the changes in wind shear, and realize the automated and accurate recording of low-altitude wind shear data.

[0047] The working principle of this device is as follows: During installation, the adjustable support leg 12 of the bottom support leg assembly 2 of the rotating base 1 is moved up and down within the support leg sleeve 11, adjusting the base 1 to a horizontal state. When there is wind, the wind cup assembly 6 rotates under the action of the wind force, driving the rotating sleeve 15 and the fixed bushing 23 fixed at its bottom to rotate. When the fixed bushing 23 rotates, the hinge rod 25 swings under the action of the gravity ball 28, driving the movable bushing 26 to move up and down on the positioning cylinder 24 through the connecting rod 27, thereby causing the sliding sleeve 29 connected to the movable bushing 26 to slide on the positioning cylinder 24, driving the recording pen 10 to move up and down.

[0048] Simultaneously, the drive motor 32 drives the active roller 30 to rotate, pulling the recording paper 9 to move between the active roller 30 and the driven roller 31. The recording pen 10 leaves a trace on the moving recording paper 9, completing the recording of wind shear data. When the detection height needs to be adjusted, the inflatable airbag 19 is pressed to inflate the connecting pipe 18, pushing the sliding cylinder 16 to rise within the rotating sleeve 15, thereby raising the rotating detection mechanism 3. The air is released by opening the exhaust pipe 21 valve 22, and under the action of the reset spring 17, the sliding cylinder 16 descends, achieving a reduction in height to meet different detection needs.
