Description

TECHNICAL FIELD

[0001] The application relates to the meteorological detection technical field, in particular to a rope speed control assembly for a strong wind ball releasing device. BACKGROUND

[0002] At present, a huge network composed of 131 sounding stations has been established nationwide. These stations work cooperatively at the same time to release meteorological balloons. These meteorological balloons bear the heavy responsibility of continuously monitoring and collecting various meteorological elements from the ground to 30,000 meters in the upper air, providing valuable data support for weather forecasting, climate research and disaster warning. A professional device called a strong wind ball releasing device (hereinafter referred to as a ball releasing device) is used in strong wind weather. The ball releasing devices used by the national sounding stations are mainly released by three major manufacturers of sounding instruments together with the sounding instruments. Although they come from different manufacturers, the ball releasing devices provided by the three manufacturers are consistent in basic principle. A 33-meter long nylon rope is wound inside the ball releasing device. The rope begins to gradually unravel at the moment when the sounding balloon is released, and expands in the air as the sounding balloon rises. The ball releasing device not only effectively solves the problem of releasing sounding balloons in strong wind weather, but also provides strong protection for the smooth progress of meteorological observation work.

[0003] In 2023, Qingdao sounding station encountered a significant problem in the use of strong wind ball releasing device: from January to December, a total of 13 abnormal meteorological balloon explosion events occurred, which directly led to the decrease of sounding height, and thus had an adverse effect on the quality of the station's detection business and the accuracy of the data. Winter gales occur frequently, which greatly increases the frequency of use of the ball releasing device. The analysis shows that the problem is partly due to the too fast speed of the rope. In the process of releasing the nylon rope to follow the balloon, the instrument is easily damaged by accidentally touching the ground at the initial stage of release. This not only increases the cost of equipment maintenance, but also seriously affects the continuity and reliability of meteorological data. SUMMARY

[0004] The device provides a rope speed control assembly for a strong wind ball releasing device, and the specific implementation is as follows:

[0005] A rope speed control assembly for a strong wind ball releasing device, comprising:

[0006] The installation cylinder as the main body of the ball releasing device is provided with a releasing disc rotating in the installation cylinder, and a nylon rope is wound on the releasing disc, and the end of the nylon rope is connected to a sounding balloon;

[0007] The damper is arranged on the mounting cylinder, and the output end of the damper is provided with a driven shaft which is connected to one side of the rotating center of the pay-off disc through a spline, and the damper rotating with the driven shaft provides a deceleration effect for the pay-off disc in the process of aerial release, thereby realizing rope speed control.

[0008] Based on the above technical scheme, by installing a damper on the pay-off disc, the stable and slow release of the nylon rope during the release of the sounding ball can be realized, thereby effectively avoiding potential risks caused by too fast release of the rope, i.e., the instrument accidentally touches the ground due to the impact force of sudden release, thereby causing the adverse consequences of failure of the entire ball release operation. Not only the safety and stability of the ball release process are significantly improved, but also the success rate of the ball release operation is greatly enhanced, thereby providing more reliable technical support for meteorological detection scientific research activities.

[0009] Preferably, the mounting cylinder is arranged in a lateral opening shape, and a detachable end cover is arranged at the opening.

[0010] Based on the above technical scheme, by arranging the end cover, the pay-off disc can be effectively sealed to ensure the dryness and cleanliness of the internal structure and avoid the adverse effects of external environmental factors on the performance of the pay-off disc. At the same time, the pay-off disc is clamped by the limiting fixed shaft, which not only enhances the stability and accuracy of the pay-off disc during rotation, but also effectively reduces the operation errors caused by shaking or deviation, thereby significantly improving the stability and reliability of the overall rotation of the pay-off disc.

[0011] Preferably, the damper comprises a seat body, and the seat body is sequentially divided into an annular adjusting chamber and a deceleration chamber along the axial direction thereof; a plurality of magnetic surfaces are equidistantly arranged in the circumferential direction in the deceleration chamber; a mounting shaft is coaxially arranged in the deceleration chamber; a plurality of magnetic blocks are equidistantly arranged on the mounting shaft in the circumferential direction; and the magnetic blocks and the magnetic surfaces are opposite in magnetism and correspond to each other.

[0012] Based on the above technical scheme, the damper is arranged between the driven shaft and the deceleration chamber with circumferentially distributed magnetic force, which fully utilizes the basic principle of magnetic interaction to create a damping mechanism. When the nylon rope starts to release, the damping effect caused by the mutual restraint between the magnetic forces can effectively slow down the release speed of the nylon rope, ensuring that it expands in a stable, orderly and controllable manner throughout the process.

[0013] Preferably, the deceleration chamber is equidistantly provided with a plurality of radial sliding grooves in the circumferential direction, each radial sliding groove is slidably provided with a sliding block, and the magnetic surface is arranged on the sliding block and faces one end of the magnetic block.

[0014] Preferably, adjacent sliding blocks are connected through arc-shaped expansion rods, and the arc-shaped expansion rods and the sliding blocks jointly form a variable-diameter circumferential structure.

[0015] Preferably, the vortex in the annular adjusting bin is provided with a tension spring reel, and one end of the tension spring reel is outwardly threaded out of the seat body, and a locking key is additionally arranged at the threaded-out position.

[0016] Preferably, an opening is arranged along the length direction in the radial sliding groove, the adjusting bin and the speed reduction bin are in communication at the opening, and any sliding block is connected to the side of the tension spring reel through the opening.

[0017] Based on the above technical scheme, by arranging the tension spring reel in the adjusting bin, the size adjustment of the magnetic damping is realized by adjusting the tension degree of the tension spring reel to drive the sliding block with the additionally arranged magnetic surface to change in diameter, and the size adjustment of the magnetic damping is realized by utilizing the magnetic attraction distance change between the magnetic surface and the magnetic block.

[0018] Preferably, a scale is arranged on the outer circumferential surface of the tension spring reel along the length direction, and the scale is used for identifying the distance between the magnetic surface and the magnetic block.

[0019] In summary, the present application has the following beneficial technical effects:

[0020] 1. The damping device connected to the pay-off drum can avoid the risk of failure of the instrument to release the ball due to the too fast speed of the nylon rope, and can greatly improve the success rate of the ball release.

[0021] 2. The utility model has the advantages of simple structure, and the damping device is arranged circumferentially between the driven shaft and the speed reduction bin, and utilizes the damping effect of the magnetic force to produce a speed reduction effect on the release of the nylon rope.

[0022] 3. The utility model discloses a damping device connected to the pay-off drum can avoid the risk of failure of the instrument to release the ball due to the too fast speed of the nylon rope, and can greatly improve the success rate of the ball release. BRIEF DESCRIPTION OF DRAWINGS
