Description

Technical Field

[0001] This utility model patent relates to the field of meteorological equipment technology, specifically to a sounding positioning correction device for a weather balloon. Background Technology

[0002] In the field of meteorological observation, weather balloons, as important upper-air sounding devices, are widely used in tasks such as collecting atmospheric physical parameters and transmitting meteorological data. The accuracy of their onboard positioning devices in obtaining spatial coordinates directly affects the validity and reliability of meteorological data. However, the upper-air environment is characterized by complex atmospheric movements, such as strong winds, turbulence, and irregular airflows. These factors can cause weather balloons and their onboard positioning devices to deviate, tilt, or even flip, resulting in significant positioning data deviations and severely impacting the accuracy of the observations.

[0003] Existing weather balloon positioning devices have significant shortcomings in dealing with complex upper-level airflow. Traditional positioning equipment typically employs passive stabilization structures (such as simple suspension cables or rigid connection frames), which are insufficient to effectively resist the dynamic torques generated by atmospheric motion, leading to instability in the device's attitude. While some devices incorporate active correction mechanisms, they often rely on unidirectional power adjustment or complex attitude control systems, resulting in structural complexity, high energy consumption, and slow response speeds. Furthermore, they have limitations in multi-dimensional spatial attitude adjustment and cannot accurately respond to airflow disturbances in three-dimensional space.

[0004] Furthermore, the signal reception capability of existing positioning devices is susceptible to the influence of the high-altitude electromagnetic environment and the device's own structure. Traditional shell designs often employ simple geometric shapes, which not only result in significant wind resistance but may also create a shielding effect on signal reception, leading to unstable positioning signal transmission. Simultaneously, the lack of a collaborative correction mechanism between the positioning data acquisition module and the external environment prevents real-time dynamic adjustments to the positioning strategy based on atmospheric motion parameters, further exacerbating the positioning error problem. Summary of the Invention

[0005] To address some or all of the aforementioned technical problems, this application provides a sounding positioning correction device for a weather balloon, which possesses the technical advantages of multi-directional active attitude adjustment technology to enhance anti-interference capabilities and an integrated design of a low-drag shell and signal enhancement.

[0006] A sounding positioning correction device for a weather balloon includes: an assembly port installed on the mounting interface of a corresponding weather balloon; an extension sling installed on the lower end face of the assembly port; an equipment truss connected to the extension sling; a first assembly interface encased in a shell, the shell being an elliptical assembly block assembled from multiple pieces and mounted on the first assembly interface; a positioning data acquisition module mounted on the first assembly interface; and a first axial flow duct disposed within the first assembly interface, containing a drive fan. Multiple first axial flow ducts are provided, each comprising a different directional axis in spatial coordinates, and the multiple first axial flow ducts do not intersect each other. Embedded signal lines are laid on the outside of the assembly blocks, with abutment springs at both ends of the signal lines, and the multiple signal lines forming receiving antennas through corresponding abutment springs.

[0007] The first axial flow duct passes through the housing, the equipment truss passes through the housing and is fixedly connected to the first assembly interface, and the positioning data acquisition module is disposed inside the housing.

[0008] By adopting the above technical solutions, a complete positioning correction system has been constructed for the meteorological balloon sounding positioning correction device.

[0009] The assembly port is connected to the weather balloon installation interface, serving as the connection hub between the device and the balloon to ensure reliable device mounting; the extended sling connects the assembly port to the equipment truss, providing structural support and, to some extent, cushioning the balloon's swaying in the airflow.

[0010] The outer side of the first assembly interface is wrapped with multiple elliptical assembly blocks. The shell is designed with a low drag coefficient to reduce the lateral thrust of high-altitude airflow on the device and ensure positioning stability.

[0011] The positioning data acquisition module is installed in the first assembly interface to collect spatial coordinate information in real time. The drive fan in the first axial flow duct is arranged through a multi-directional axis to generate thrust in different directions. When the device is deviated or tilted due to airflow, the drive fan adjusts its speed and direction to generate a reverse compensation torque, corrects the device's attitude, and ensures the accuracy of positioning data acquisition.

[0012] Embedded signal lines are laid on the outside of the assembly block and form a receiving antenna through abutment springs, which effectively enhances the signal reception capability, avoids the shielding of the signal by the shell, and ensures stable transmission of positioning signals.

[0013] Optionally, the assembly port includes a flange port, and the mounting interface is fixedly connected to the structural frame of the corresponding weather balloon.

[0014] By adopting the above technical solution, the assembly port includes a flange port, which is fixedly connected to the structural frame of the weather balloon. This connection method provides a solid connection strength, which can withstand the force of high-altitude airflow on the device and ensure that the device will not fall off under complex weather conditions.

[0015] Meanwhile, the standardized flange port design facilitates rapid adaptation to existing weather balloons, reduces installation difficulty, shortens installation time, improves operational efficiency, and meets the needs of rapid deployment for emergency weather detection.

[0016] Optionally, the two ends of the extension sling are connected to the assembly port and the equipment truss respectively via ball joints, and a support rod is provided inside the extension sling.

[0017] By adopting the above technical solution, the two ends of the sling are connected to the assembly port and equipment truss through the ball shaft, so that the sling can rotate freely within a certain range, flexibly adapt to the swing of the balloon in the airflow, avoid stress concentration and attitude coupling problems caused by rigid connection, and protect the structural integrity of the device.

[0018] Optionally, the equipment truss is provided with multiple correction units, each correction unit including a second assembly interface and a second axial flow duct.

[0019] Optionally, the assembly port includes a surrounding interface located at the edge of the equipment pod on the lower end face of the weather balloon, and multiple extension slings are provided. The assembly port, the multiple extension slings, and the equipment truss are connected in multiple sets of triangular fixed connections.

[0020] Optionally, multiple temperature sensors are installed on the equipment truss, the vertical cross-section of the equipment truss is a rhomboid structure, and the equipment truss is a triangular frame structure.

[0021] By adopting the above technical solution, the support rod installed inside the sling provides axial rigid support on the basis of flexible connection, ensuring the stability of the central axis of the device when swinging. Combined with the triangular fixed connection structure, a composite support system of flexible buffer and rigid positioning is formed, which greatly improves the stability of the device, controls the tilt angle to a very small range, and effectively reduces the positioning deviation caused by the shaking of the device.

[0022] By adopting the above technical solution, the equipment truss is equipped with multiple correction units, including a second assembly interface and a second axial flow duct, forming a multi-level correction system.

[0023] Multiple extension slings, assembly ports, and equipment trusses form multiple sets of triangular fixed connection structures, further enhancing the overall structural stability. The mechanical properties of the triangular structure enable the device to withstand greater external forces without deformation.

[0024] When high-altitude airflow is complex and variable, the number of correction units can be flexibly increased or decreased according to the actual situation to make more precise corrections to the device's attitude, adapting to environments with different altitudes and airflow intensities, significantly improving correction accuracy, and further ensuring positioning accuracy. In addition, temperature sensors installed on the equipment truss collect atmospheric temperature data in real time. Combined with information from the positioning data acquisition module, this data is transmitted to the central processor via the communication module to compensate for and correct environmental factors such as air pressure deviations caused by temperature and equipment thermal deformation. This improves the device's environmental adaptability, constructs a closed-loop control system, and comprehensively enhances positioning accuracy.

[0025] Optionally, the receiving antenna is connected to the communication module, which is installed in the weather balloon. The communication module is connected to the positioning data acquisition module and multiple driving fans.

[0026] Optionally, a counterweight is provided within the second assembly interface.

[0027] Optionally, the counterweight may be a storage battery.

[0028] By adopting the above technical solutions and optimizing the counterweight design, the stability of the device's structure during lifting and levitation is improved.

[0029] The receiving antenna is connected to the communication module, which in turn connects the positioning data acquisition module and the drive fan, enabling rapid data transmission and control command issuance. This allows the device to adjust the working state of the drive fan in a timely manner based on positioning data and environmental information, forming an efficient positioning correction feedback mechanism.

[0030] The counterweight block installed in the second assembly interface is made of a storage battery, which not only optimizes the center of gravity distribution of the device and enhances static stability, but also powers the device, reduces the space occupied by additional energy equipment, reduces the overall weight, realizes the integrated optimization of structure and function, and improves the practicality and reliability of the device.

[0031] Compared with the prior art, this application includes at least one of the following beneficial technical effects of the sounding positioning correction device for weather balloons:

[0032] Traditional positioning devices often employ passive stabilization structures or unidirectional dynamic adjustment, making them ill-suited for complex airflow patterns. Positioning devices are susceptible to large positioning errors due to deviations and tilts caused by complex high-altitude airflow.

[0033] The two ends of the extension sling in this application are connected by a ball joint, which can rotate freely to adapt to the swing of the balloon and avoid stress concentration; the internal support rod of the sling provides axial rigid support, and together with multiple sets of triangular fixed connection structures, a composite support system of flexible buffer and rigid positioning is formed.

[0034] The elliptical assembly block design reduces wind resistance, minimizes lateral thrust, and ensures device stability.

[0035] By arranging the first axial flow duct in multiple directions, the driving fan can generate thrust in different directions, adjust the device's attitude in real time, and quickly generate a reverse compensation torque when the device deviates or tilts.

[0036] Meanwhile, the embedded signal circuitry forms a receiving antenna, enhancing signal reception capabilities, avoiding shielding by the housing, ensuring stable transmission of positioning signals, and further guaranteeing positioning accuracy.

[0037] By optimizing the mechanical structure design and adopting innovative structures such as multi-directional first axial flow duct active attitude adjustment, elliptical modular low wind resistance shell, and splicable embedded signal line receiving antenna, multi-dimensional compensation for high-altitude atmospheric disturbances is achieved, effectively improving the stability and positioning accuracy of the positioning device. It has advantages such as compact structure, rapid response, and low energy consumption, providing a reliable technical solution for the precise positioning of meteorological balloons.

[0038] The multi-module modular shell design supports rapid on-site assembly, reducing the difficulty of field operations and improving the practicality and reliability of the device.

[0039] In terms of structural design, the truss of the equipment in this application is equipped with multiple correction units, which can be flexibly added or removed according to the actual airflow conditions to form a multi-level correction system that can adapt to different altitudes and different airflow intensities.

[0040] The flange port or surround interface design of the assembly port facilitates rapid adaptation to existing mainstream weather balloons and meets the needs of rapid deployment for emergency weather detection.

[0041] This application combines a counterweight with a battery, which not only enhances static stability by optimizing the center of gravity distribution, but also provides power to the device, reducing the space occupied by additional energy equipment and thus reducing the overall weight.

Detailed Implementation

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this utility model patent clearer, the technical solutions of the embodiments of this utility model patent will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model patent, not all of them. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model patent are within the scope of protection of this utility model patent.

[0050] This application discloses a sounding positioning correction device for a weather balloon.

[0051] Reference Figure 1 A sounding positioning correction device for a weather balloon 12 includes a connecting structure and operating equipment, with the operating equipment installed on the connecting structure.

[0052] The connection structure includes assembly port 1, extension sling 2, and equipment truss 3.

[0053] Assembly port 1 is installed on the mounting interface 11 of the corresponding weather balloon 12. Assembly port 1 includes a flange port, and mounting interface 11 is fixedly connected to the structural frame of the corresponding weather balloon 12.

[0054] The flange port is rigidly connected to the aluminum alloy frame of the weather balloon 12. The standardized flange interface conforms to general aviation connection standards, reducing installation time and significantly improving equipment compatibility.

[0055] The extension sling 2 is installed on the lower end face of the assembly port 1, and a support rod is installed inside the extension sling 2.

[0056] Ensure that extension sling 2 maintains a straight shape under dynamic load.

[0057] The outer layer of the extension sling 2 is a fiber braided layer, and the inner layer integrates a 4-core shielded cable to transmit power signals and control signals synchronously, reducing the impact of external electromagnetic interference on data transmission.

[0058] In some embodiments, the two ends of the extension sling 2 are connected to the assembly port 1 and the equipment truss 3 respectively via ball bearings.

[0059] The ball bearing uses a self-lubricating spherical bearing, providing rotational freedom and allowing it to absorb the sway amplitude of the weather balloon body within a range of ±30° in real time.

[0060] This operating mode is suitable for a single first assembly interface 4 structure.

[0061] In some embodiments, the assembly port 1 includes a surrounding interface disposed on the edge of the equipment pod on the lower end face of the weather balloon 12. Multiple assembly ports 1 and extension slings 2 are provided, and multiple sets of triangular fixed connection structures are formed between the multiple assembly ports 1, multiple extension slings 2, and equipment trusses 3.

[0062] The working principle and effect are that the equipment truss 3 forms an equilateral triangle support structure, which can improve the uniformity of stress distribution at the connection by 80%.

[0063] When encountering strong winds, the offset of the device's central axis is controlled within a certain swing range, which is significantly better than the traditional single-dry drive structure and effectively avoids the drift of the positioning reference caused by the flexible deformation of the balloon.

[0064] Furthermore, preferably, the assembly port 1 is a triangular structure, and the first assembly interface 4 and multiple correction units 7 are respectively installed at the ends of the triangular structure.

[0065] For example, in terms of specific structure: the triangular assembly port 1 is made of lightweight alloy forging, with a side length of 25cm and a thickness of 6mm, and can withstand dynamic load forces in three directions.

[0066] The end point has a pre-set threaded mounting hole, which, together with the quick-release bolt, enables the first assembly interface 4 and the correction unit 7 to be disassembled and assembled in seconds, meeting the needs of emergency maintenance in the field.

[0067] Combine, refer to Figure 2 The first assembly interface 4 is installed on the equipment truss 3. The positioning data acquisition module 41 is installed inside the first assembly interface 4, and the outside is wrapped with an elliptical assembly block 5.

[0068] For example, in terms of specific structure: the five assembled blocks have a major axis of 30cm and a minor axis of 20cm, which reduces the drag coefficient compared to a traditional cube.

[0069] For example, in terms of specific structure: the assembly block 5 is assembled from 8 SMC molded fiberglass pieces, and the joints are sealed with silicone rubber, which can withstand temperature shocks of -60℃ to +80℃ and high-altitude ultraviolet radiation.

[0070] Furthermore, the first assembly interface 4 is provided with multiple first axial flow ducts 6, and a drive fan 61 is provided inside the first axial flow ducts 6. The multiple first axial flow ducts 6 include different directional axes in spatial coordinates (such as X, Y, Z axes and diagonal directions) and do not intersect each other.

[0071] The fan 61 can be driven in both forward and reverse directions.

[0072] For example, in terms of specific structure: the drive fan 61 uses a brushless DC motor. There are no fewer than 3 sets of axial flow ducts orthogonally distributed (no fewer than 1 set in each of the positive and negative directions of the X / Y / Z axes), covering three-dimensional space.

[0073] Multiple first axial flow ducts 4 are distributed along the orthogonal directions (X, Y, Z axes) and diagonal directions in three-dimensional space.

[0074] Furthermore, in conjunction with reference Figure 3 Embedded signal lines 51 are laid on the outside of the assembly block 5. Abutment springs 52 are set at both ends of the signal lines 51. Multiple signal lines 51 form a receiving antenna through the corresponding abutment springs 52.

[0075] Operating principle and effect: Signal line 51 adopts an impedance microstrip antenna design, which improves signal reception sensitivity in low temperature environments.

[0076] The contact spring 52 is made of beryllium bronze plated with gold, with a contact resistance of ≤10mΩ, ensuring that a continuous conductive surface is formed after the housing is assembled, and reducing signal transmission loss by 60% compared with traditional external antennas.

[0077] The abutting spring 52 includes a rhomboid deformation abutting structure design, wherein the abutting spring 52 adopts a rhomboid deformation abutting design to achieve abutting connection.

[0078] Embedded signal lines 51 are laid on the outside of the assembly block 5. Abutment springs 52 are set at both ends of the signal lines 51. Multiple signal lines 51 form a receiving antenna through the corresponding abutment springs 52.

[0079] This addresses the defects caused by metal shrinkage and structural brittleness in low-temperature environments, leading to gaps in connections or damage from impacts.

[0080] For example, in terms of specific structure: the abutment spring 52 includes a rhomboid metal piece with a long side of 12mm and a short side of 8mm, and the angle between the two diagonals is 110°.

[0081] When the ambient temperature at high altitude drops to -50℃, the metal material undergoes approximately linear contraction due to thermal expansion and contraction. The diamond-shaped spring automatically compensates for the changes in the spacing between the assembly blocks 5 through elastic compression in the short diagonal direction, so that the contact pressure is always maintained within a certain range, avoiding connection gaps caused by low-temperature contraction.

[0082] When the device vibrates due to airflow impact, the multi-directional elastic deformation capability of the rhomboid spring can absorb the vibration energy, avoiding spring breakage or contact failure caused by rigid collision.

[0083] • Verified by high and low temperature vibration composite test, the design can work continuously for 24 hours without contact failure under vibration conditions of -50℃ and 5g acceleration, which is 4 times more reliable than the traditional structure.

[0084] In some embodiments, multiple temperature sensors are provided on the equipment truss 3, the vertical cross section of the equipment truss 3 is a rhomboid structure, and the equipment truss 3 is a triangular frame structure.

[0085] For example, the specific structure: rhomboid cross section: the aerodynamic design with a 120° apex angle and a 60° base angle allows high-altitude condensate to slide down the slope at a wind speed of 0.2 m / s, avoiding the formation of an ice layer on the frame surface and ensuring the long-term reliable operation of the temperature sensor.

[0086] Temperature sensor: Collects atmospheric temperature data in real time, corrects temperature parameters in barometric altitude calculation, and optimizes operational accuracy for altitude errors.

[0087] Combine, refer to Figure 4 Multiple correction units 7 are provided on the equipment truss 3. The correction unit 7 includes a second assembly interface 71 and a second axial flow duct 72. A counterweight block 73 (preferably a battery) is provided inside the second assembly interface 71.

[0088] Battery counterweight: enhances static stability, supplies power to the entire system, increases battery life, and reduces space occupation.

[0089] Each correction unit 7 is completely identical to the main frame structure and supports up to 3 levels of cascaded expansion. When the main frame's correction capability is insufficient, the secondary correction unit 7 is automatically activated to meet the attitude correction requirements of ultra-high altitude strong turbulence environment. The correction accuracy increases linearly with the number of units.

[0090] Furthermore, the receiving antenna is connected to the communication module, which is installed on the weather balloon 12. The communication module is connected to the positioning data acquisition module 41 and multiple drive fans 61.

[0091] The first axial flow duct 6 passes through the shell, the equipment truss 3 passes through the shell and is fixedly connected to the first assembly interface 4, and the positioning data acquisition module 41 is set inside the shell.

[0092] The first assembly interface 4 and the housing and receiving antenna thereon have the same structural design as the second assembly interface 71, and the first axial flow duct 6 and the second axial flow duct 72 have the same structural design.

[0093] A drive fan is installed inside the second axial flow duct 72 to assist in correcting the attitude of the device.

[0094] The modular design with the same structure has the advantage that there is no need to distinguish between the main and auxiliary frames during maintenance; the faulty unit can be directly replaced, thus shortening the maintenance time per operation.

[0095] The communication module adopts a dual-redundant bus design, and the positioning data acquisition module 41 synchronously outputs data protocols to ensure reliable transmission of control commands in complex electromagnetic environments.

[0096] In this embodiment of the application, the implementation principle of a sounding positioning correction device for a weather balloon 12 is as follows:

[0097] Precise positioning is achieved through the design of structural stability support, optimized resistance shell, and multi-axis dynamic correction operation:

[0098] Mechanical connection layer: Assembly port 1 forms a rigid / flexible connection with the balloon through a flange or surround interface. Combined with the rigid support of the triangular fixed structure, a composite system of "flexible buffer + rigid positioning" is constructed to effectively isolate the balloon body's swing from interfering with the device's attitude.

[0099] The elliptical assembly block 5, through its low wind resistance design, generates compensating thrust in real time through multi-directional axial air ducts, forming a three-dimensional torque balance, which physically counteracts the effects of high-altitude airflow disturbances.

[0100] An embedded antenna array on the housing surface enhances signal reception. Combined with real-time atmospheric parameter data collected by a temperature sensor, it provides environmental compensation for positioning data.

[0101] Embedded signal lines 51 are laid on the outside of the assembly block 5.
