Description

Technical Field

[0001] This application relates to the field of meteorological detection technology, and in particular to a bidirectional line-laying assembly for a high-wind ball-laying device. Background Technology

[0002] Upper-air sounding is a key technology in meteorology, crucial for improving the accuracy of weather forecasts and advancing global meteorological research. It primarily involves releasing balloons carrying radiosondes at specific times to collect vertical meteorological observation data from the ground to high altitudes. This data includes key meteorological elements such as temperature, humidity, air pressure, wind speed, and wind direction, which are irreplaceable for understanding atmospheric conditions, predicting weather changes, and studying climate change. To ensure the comparability and interactivity of meteorological observation data globally, the World Meteorological Organization has established a unified set of standards. According to these standards, all countries must conduct upper-air sounding within the same time period (i.e., one hour before 00:00 and 12:00 UTC each day). In China, this standard is specified by national radiosonde stations conducting launches at 07:15 and 01:15 daily. This timing not only ensures global data synchronization but also facilitates the global exchange of radiosonde data.

[0003] In meteorological upper-air sounding, a rope is typically used to connect the radiosonde to a hydrogen balloon. Hydrogen balloons are widely used as launch vehicles due to their lightweight and high buoyancy. Before release, the radiosonde undergoes rigorous inspection to ensure proper functioning. Supported by the BeiDou Navigation Satellite System, remote monitoring and real-time data transmission of the radiosonde are possible. However, in current high-wind balloon launchers for meteorological sounding, the distance between the instrument and the balloon is often too close. When they approach the tropopause (approximately 18,000 meters above the ground), especially near the turbulent zone, the instrument often experiences violent up-and-down rolling motions due to strong winds. This unstable motion significantly increases the risk of the instrument rupturing the balloon, frequently leading to abnormal balloon bursts ("balloon burst") near the crucial 18,000-meter troposphere. This reduces the sounding altitude and directly impacts the quality of the station's sounding operations and the quality of the balloons produced by the manufacturer. Summary of the Invention

[0004] This device provides a bidirectional cable feeding assembly for a high-wind ball bearing device, and the specific implementation method is as follows:

[0005] A bidirectional line feeding assembly for a high-speed ball bearing device includes:

[0006] The ball release device and the line release drum inside the ball release device are equipped with a nylon rope wound on the line release drum. The two ends of the nylon rope pass through the ball release device and are respectively connected to the sounding ball and the sounding instrument.

[0007] The middle section of the nylon rope is wound around the circumference of the release drum. When the nylon rope is launched, both ends are released outward, so that there is a sufficient safe distance between the radiosonde and the radiosonde.

[0008] Based on the above technical solution, by winding the middle section of the nylon rope along the circumference of the release drum, the radiosonde and the radiosonde can perform opposite and synchronous release actions relative to the release device during the release operation. This increases the distance between them, reducing the abnormal balloon bursting phenomenon that frequently occurs at an altitude of 18,000 meters near the tropopause due to insufficient distance. This significantly improves the achievable altitude of radiosonde operations, i.e., the maximum altitude that radiosonde can reach. Moreover, it greatly optimizes the quality score of winter weather balloons, further ensuring and improving the accuracy and reliability of meteorological observation data.

[0009] Preferably, the ball feeder is equipped with a damper, and the output end of the damper is connected to the shaft of the feed drum via a spline.

[0010] Preferably, the ball release device includes a hollow cylinder, with the upper and lower ends of the cylinder respectively having radially opposite outlets for the ends of nylon ropes to pass through.

[0011] Preferably, the cylinder body is open on the side, and an end cap is installed at the open part. A concave-convex columnar structure for rotation limit is provided between the end cap and the wire feeding cylinder.

[0012] Based on the above technical solutions, by adding a damper to the line-feeding drum of the ball-feeding device, the rotational damping force of the line-feeding drum was successfully increased, thereby achieving precise control of the line-feeding speed, slowing down the line-feeding rate of the line-feeding drum, and making the line-feeding process more stable and controllable. At the same time, it effectively avoids the risk of falling to the ground that may be caused by the excessively fast release speed of the radiosonde and the excessive distance between it and the radiosonde ball in the initial stage of bidirectional line-feeding operation. This not only enhances the safety and stability of line-feeding, but also ensures the smooth release of the radiosonde under complex weather conditions, providing a solid technical guarantee for the accurate collection of meteorological observation data.

[0013] Preferably, the ball feeder includes a cylinder, the inside of which is axially divided into three cavities by two partitions, and the feed cylinder is installed in the middle cavity.

[0014] Preferably, the upper and lower parts of the two side cavities in the cylinder are respectively provided with a second rope outlet and a first rope outlet, and a third rope outlet is provided on the partition for the end of the nylon rope to pass through.

[0015] Based on the above technical solutions, the use of a partition effectively isolates the lead-out portion of the nylon rope from the rotating release structure of the lead-out drum. This ensures that the nylon rope does not directly contact or interfere with the rotating part of the lead-out drum during the lead-out process, thus greatly reducing potential problems caused by friction or entanglement. Simultaneously, the nylon ropes at both ends are guided to unfold to both sides, further preventing entanglement during lead-out, improving the stability and reliability of the bidirectional lead-out operation, simplifying the lead-out process, and increasing work efficiency, providing strong technical support for the smooth execution of meteorological observation tasks. A fuse device can be added to the internal structure of the launcher, and a parachute can be equipped for the radiosonde. After the meteorological observation task is successfully completed, the fuse can be used to quickly and accurately disconnect the connection between the radiosonde and the radiosonde. Subsequently, the deployment of the parachute allows for the safe and secure recovery of the radiosonde, enabling its reuse.

[0016] Preferably, both ends of the rotating shaft are provided with side plates, and nylon rope is wound around the rotating shaft and between the two side plates.

[0017] Preferably, the partition is provided with an annular baffle inward, and the outer peripheral surface of the side plate abuts against the inner side of the annular baffle, and the thickness of the annular baffle is the same as the thickness of the side plate.

[0018] Based on the above technical solution, there is a rotation gap between the side plate and the partition. This gap can become a potential jamming risk point for the nylon rope 2 during the unwinding process. In order to effectively avoid this risk, the annular partition 306 is used to fit tightly around the rotation gap, which plays a blocking role and effectively prevents the nylon rope 2 from accidentally getting stuck in the rotation gap during the unwinding process.

[0019] In summary, this application includes the following beneficial technical effects:

[0020] 1. This utility model, by winding the middle section of the nylon rope around the circumference of the release drum, allows the sounding balloon and the sounding instrument to release the line simultaneously in opposite directions relative to the release device during the release of the line. This effectively reduces or eliminates the abnormal balloon burst phenomenon near the tropopause at an altitude of 18,000 meters, increases the sounding altitude, and improves the quality score of winter weather balloons.

[0021] 2. This utility model has a simple structure. By adding a damper to the feeding drum of the ball feeder, the rotational damping force of the feeding drum is increased, thereby slowing down the feeding speed of the feeding drum and effectively avoiding the problem of the sounding instrument falling to the ground due to the increased release speed after bidirectional feeding.

[0022] 3. This utility model uses a partition to isolate the nylon rope from the rotational release of the pay-off drum, and the nylon rope at both ends extends to both sides, thus avoiding the problem of tangling during the pay-off process and improving the stability of bidirectional pay-off.

[0034] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail.

[0035] This application discloses a bidirectional wire feeding assembly for a high-wind ball feeding device.

[0036] Example 1

[0037] Reference Figures 1 to 3 This embodiment discloses a bidirectional line-releasing assembly for a high-wind ball launcher, including a ball launcher 3 and a line-releasing drum 7 disposed inside the ball launcher 3. A nylon rope 2 is wound on the line-releasing drum 7, and the two ends of the nylon rope 2 pass through the ball launcher 3 and are respectively connected to the radiosonde 1 and the radiosonde 5. In this structure, the middle section 203 of the nylon rope 2 is wound around the circumference of the line-releasing drum 7. When launching, both ends of the nylon rope 2 are released outward, so that there is a sufficient safe distance between the radiosonde 1 and the radiosonde 5. A damper 4 is provided on the ball launcher 3, and the output end of the damper 4 is connected to the rotating shaft 701 of the line-releasing drum 7 through a spline.

[0038] The ball release device 3 includes a hollow cylinder 301. The upper and lower ends of the cylinder 301 are respectively provided with radially opposite outlets for the end of the nylon rope 2 to pass through. In this structure, the cylinder 301 is open on the side, and an end cap 6 is installed at its opening. A concave-convex columnar structure for rotation limit is provided between the end cap 6 and the release cylinder 7.

[0039] The specific implementation process is as follows: After the radiosonde 5 is running normally, the radiosonde ball 1 is released manually; in the initial stage of launch, the damper 4 rotates coaxially with the release drum 7 to provide a deceleration effect, so that the initial take-off speed of the radiosonde ball 1 is greater than the release speed of the nylon rope 2, so that the radiosonde 5 will not fall to the ground during take-off; during the ascent, the nylon rope 2 is continuously released, and after reaching the detection airspace, the nylon rope 2 is detached from the release drum 7, and its two ends are always connected to the radiosonde ball 1 and the radiosonde 5, and a safe distance is maintained between the two.

[0040] Example 2

[0041] Reference Figures 4 to 5 Based on the above embodiments, this embodiment also discloses a bidirectional line feeding assembly for a large-scale ball feeding device. The ball feeding device 3 includes a cylinder 301. The inside of the cylinder 301 is axially divided into three cavities by two partitions 304, and the line feeding drum 7 is installed in the middle cavity. In this structure, the line feeding is separated by the rotation of the line feeding drum 7 and the exit of the nylon rope 2. The first rope end 202 and the second rope end 203 feed the line to both sides respectively, which can prevent the two from getting tangled and affecting the overall smoothness of the nylon rope 2 feeding.

[0042] The upper and lower parts of the two side cavities in the cylinder 301 are respectively provided with a second rope outlet 303 and a first rope outlet 302, and a third rope outlet 305 is provided on the partition plate 304 for the end of the nylon rope 2 to pass through. The two ends of the nylon rope 2 are the first rope end 202 and the second rope end 203, respectively. The first rope end 202 passes through the first rope outlet 302 and is connected to the radiosonde 5, and the second rope end 203 passes through the second rope outlet 303 and is connected to the radiosonde ball 1.

[0043] Example 3

[0044] Reference Figure 4 and Figure 5 Based on the above embodiments, this embodiment also discloses a bidirectional line-releasing assembly for a large-scale ball-releasing device. Both ends of the rotating shaft 701 are provided with side plates 702. A nylon rope 2 is wound around the rotating shaft 701 and between the two side plates 702. In this structure, the partition plate 304 has an inwardly provided annular baffle 306. The outer circumferential surface of the side plate 702 abuts against the inner side of the annular baffle 306, and the thickness of the annular baffle 306 is the same as the thickness of the side plate 702. Alternatively, the thickness of the annular baffle 306 can be greater than the thickness of the side plate 702. The extended portion is designed as a barb structure. There is a rotational gap between the side plate 702 and the partition plate 304. Using the annular baffle 306 to block the rotational gap can prevent the nylon rope 2 from getting stuck in the gap, thereby improving the stability of the nylon rope 2 release.
