Description

Technical Field

[0001] This invention relates to the field of upper-air meteorological detection equipment technology, and in particular to a disposal device and control method for meteorological balloons. Background Technology

[0002] With the continuous development of upper-air meteorological sounding technology, fully automated upper-air meteorological sounding systems have gradually become core equipment in the field of meteorological observation. These systems can automatically complete the entire process of balloon inflation, radiosonde deployment, and meteorological data reception. They are characterized by a high degree of automation and the ability to operate unattended, and can adapt to the routine meteorological sounding needs of remote and harsh environments. The working cabin of a fully automated upper-air meteorological sounding system is usually divided into three compartments: a working chamber, a storage chamber, and a balloon deployment tube. A sealed door is installed between the storage chamber and the balloon deployment tube. The radiosonde storage box is stored on a shelf in the storage chamber. It can be picked up by a transfer mechanism and sent into the balloon deployment tube through the sealed door to complete the balloon inflation and deployment operations in sequence. After the balloon is deployed, the empty storage box is returned to the storage chamber through the sealed door.

[0003] In related technologies, when the system malfunctions, such as detecting hydrogen leakage during inflation, damage to the balloon, a failure of the inflation equipment, or a user temporarily canceling the balloon release task, it is necessary to handle the balloons that have been fully inflated in the release tube, vent the hydrogen from the balloons, and reset the equipment. Otherwise, the system will be unable to carry out the next balloon release task.

[0004] Currently, the disposal of these inflated balloons is entirely done manually. Operators must travel to the system installation site, enter the balloon release tube, manually remove the balloon, and purge the internal hydrogen. However, this manual balloon disposal method has many drawbacks and safety hazards: On the one hand, the volume of the inflated balloon far exceeds the passage size of the sealed door, making it impossible to return directly to the storage room with the storage box. On the other hand, the balloon and storage box continuously occupy the space of the balloon release tube, which will cause the entire system to stop and make it impossible to perform subsequent balloon release tasks. On the other hand, the balloon is filled with a large amount of hydrogen. Manual disassembly and venting can easily cause hydrogen leakage, which poses a risk of causing a fire and explosion accident, making it difficult to guarantee the safety of the operation. In addition, fully automated upper-air meteorological detection systems are mostly deployed at remote sites that are not suitable for long-term personnel presence. Operators need to spend a lot of time and manpower to travel back and forth to handle the situation. Furthermore, while waiting for manual intervention, the hydrogen-filled balloons remain in the balloon release tube for an extended period of time, which poses a continuous safety risk. Overall, the operation and maintenance efficiency and safety level are difficult to meet the needs of actual applications. Summary of the Invention

[0005] In response to the shortcomings of the existing production technologies, the applicant provides a disposal device and control method for weather balloons, thereby overcoming the defects of existing technologies, such as high safety risks, time-consuming and labor-intensive manual disposal of hydrogen-filled weather balloons, and low system reset efficiency under abnormal operating conditions. This device can break up hydrogen-filled balloons inside the balloon release tube without the need for on-site manual intervention, thus improving the operation and maintenance safety and efficiency of unattended upper-air meteorological detection systems.

[0006] The technical solution adopted in this invention is as follows: This invention provides a disposal device for weather balloons, comprising: A first link assembly and a second link assembly are symmetrically spaced apart in a first horizontal direction. The first linkage assembly includes a first base, a first link, and a second link. The first base is connected to one end of the first link, and the other end of the first link is connected to the second link. A first intermediate member is provided at the connection position between the first link and the second link. A rotatable first shaft is provided at the end of the second link away from the first link. The second linkage assembly includes a second base, a third link, and a fourth link. The second base is connected to one end of the third link, and the other end of the third link is connected to the fourth link. A second intermediate member is provided at the connection position between the third link and the fourth link. A rotatable second pivot is provided at the end of the fourth link away from the third link. The first driving source has its output end in contact with the first intermediate rod. The second drive source has its output end in contact with the second intermediate rod. The first roller is connected to the first rotating shaft and rotates synchronously with the first rotating shaft. The second roller is connected to the second rotating shaft and rotates synchronously with the second rotating shaft. A third drive source is connected to the first roller or the second roller via a transmission connection; The first roller and the second roller are provided with meshing transmission gears at the same end in the axial direction. The first drive source and the second drive source are used to extend synchronously to drive the first linkage assembly and the second linkage assembly to approach each other until the first roller and the second roller collide; the third drive source is used to drive the roller connected to it to rotate, and drive another roller to rotate synchronously in the opposite direction through the transmission gear, so as to squeeze and break the weather balloon located between the two rollers. Its beneficial effects are as follows: The device can be directly integrated into the balloon launch tube of a fully automated upper-air meteorological detection system. In the event of abnormal conditions such as hydrogen leakage, balloon rupture, equipment failure, or temporary cancellation of the mission, it can automatically complete the breaking of the hydrogen-filled balloon without the need for operators to go to the site to manually operate the balloon launch tube. This fundamentally avoids the risk of hydrogen leakage and explosion during manual disassembly and venting. At the same time, it significantly shortens the abnormal handling cycle, allowing the system to quickly reset and execute subsequent balloon launch tasks, significantly improving the operational safety and continuous operation capability of unattended sites.

[0007] As a further improvement, the first roller body is divided into a first roller segment and a second roller segment in sequence along the axial direction, and the spiral first protrusions on the outer peripheral surfaces of the two roller segments rotate in opposite directions; the second roller body is divided into a third roller segment and a fourth roller segment in sequence along the axial direction, and the spiral second protrusions on the outer peripheral surfaces of the two roller segments rotate in opposite directions, and the positions of the first protrusion and the second protrusion correspond to each other, forming an engagement area for breaking balloons when the two roller bodies come into contact. Specifically, when the two rollers rotate synchronously in opposite directions, the spiral protrusions with opposite directions of rotation will apply a converging force along the axial direction of the rollers to the surface of the contacted balloon, causing the two ends of the balloon to continuously move towards the center of the rollers along the axial direction. Its beneficial effects are as follows: In view of the "larger at the top and smaller at the bottom" shape of hydrogen-filled balloons, the reverse spiral structure can effectively prevent the balloon from slipping off from both ends of the roller body during the breakage process, ensuring that the entire balloon enters the breakage area between the two roller bodies, greatly improving the success rate and thoroughness of balloon breakage treatment, and avoiding the failure of balloons being partially unbroken or stuck in the device.

[0008] As a further improvement, both the first protrusion and the second protrusion are meshing tooth structures, and when the first roller body and the second roller body abut against each other, the first protrusion and the second protrusion mesh with each other; Its beneficial effects are as follows: the intermeshing tooth structure can generate continuous shearing and squeezing forces during rotation, which is more effective at breaking balloon skins than smooth rollers, and can quickly cut and crush balloons, shortening the time for breaking and handling; at the same time, the intermeshing tooth structure has a self-cleaning effect, which can prevent the broken balloon skins from entangled and adhering to the roller surface, ensuring the reliability of the device in long-term operation.

[0009] As a further improvement, the first link and the third link are both straight rod structures, and the second link and the fourth link are both L-shaped structures; Its beneficial effects are as follows: the combination of straight rod and L-shaped rod in the linkage structure can provide sufficient opening and closing stroke for the roller body, ensuring that the linkage assembly will not interfere with the inflation process when the balloon is in normal inflation state, and can also make the end roller body accurately aligned with the middle of the balloon to the break position when closed. At the same time, the L-shaped structure effectively reduces the overall space occupied by the linkage assembly, which is suitable for the limited installation environment inside the balloon tube.

[0010] As a further improvement, the first and second drive sources are linear drive cylinders that operate synchronously, and the third drive source is a rotary drive motor. Its beneficial effects are as follows: the synchronous cylinder can ensure that the movement speed and extension of the connecting rod assembly on both sides are completely consistent, avoiding the problems of uneven load and misalignment of the rollers on both sides, and the clamping process is stable and reliable; the power transmission efficiency is high by using a rotary motor in conjunction with the end gear transmission, the synchronization of the two rollers rotating in opposite directions is good, and the pneumatic and electric drive components are technically mature, inexpensive, and easy to maintain and replace later.

[0011] As a further improvement, the treatment device also includes a hydrogen pipeline system, which includes an inflation branch equipped with an inflation solenoid valve, an extraction branch equipped with an extraction solenoid valve, and an extraction machine, which can switch the inflation path and the extraction path by opening and closing the solenoid valve. Its beneficial effects are as follows: before performing the crushing action, most of the hydrogen in the balloon can be pre-expelled through the evacuation branch, which greatly reduces the amount of hydrogen leakage at the moment of crushing and further reduces the risk of combustion and explosion; and after the air pressure inside the balloon is lower than the external air pressure, the balloon handle will close under the action of atmospheric pressure, and the remaining small amount of hydrogen can still support the balloon to maintain an upright state, which will not affect the subsequent clamping and crushing action of the roller, thus taking into account both the safety of disposal and the reliability of the action.

[0012] As a further improvement, the processing device also includes a conveying component, which is a linear drive module for carrying and conveying the storage box of the radiosonde, driving the storage box to reciprocate between the storage chamber and the position below the first roller and the second roller. Its beneficial effects are as follows: the broken balloon debris can fall directly into the storage box below without the need for an additional independent debris collection structure. The conveying component can directly transport the storage box carrying the debris to the sealed door, and work with the system's existing transfer robot to complete the storage box return operation. After the disposal is completed, there is no need for manual cleaning of the balloon release tube, realizing full automation from disposal to reset, and it has strong compatibility with the existing fully automatic upper-air meteorological detection system.

[0013] As a further improvement, the outer peripheral surface of the first rotating shaft is provided with at least one first mating protrusion, and the inner hole of the first roller body is provided with a matching first mating groove. The first rotating shaft drives the first roller body to rotate synchronously through the engagement of the protrusion and the groove. The outer peripheral surface of the second rotating shaft is provided with at least one second mating protrusion, and the inner hole of the second roller body is provided with a matching second mating groove. The second rotating shaft drives the second roller body to rotate synchronously through the engagement of the protrusion and the groove. Its beneficial effects are as follows: the snap-fit ​​transmission connection method has no risk of slippage, which can ensure the synchronous rotation of the shaft and the roller, and the power transmission is stable and reliable; at the same time, the detachable snap-fit ​​structure facilitates the disassembly and replacement of the roller. When the roller teeth are worn, maintenance personnel can quickly replace the roller, which greatly reduces the difficulty and cost of later maintenance.

[0014] As a further improvement, the first connecting rod assembly and the second connecting rod assembly are symmetrically arranged on opposite sides of the air balloon inflation position inside the balloon launch tube, and the first base and the second base are both fixedly installed on the inner wall of the balloon launch tube. Its beneficial effects are as follows: the entire device is directly integrated inside the balloon release tube, without occupying the space of the storage room or working room, and without requiring major modifications to the existing system's cabin structure or original equipment layout, making it highly adaptable to on-site installation; the symmetrical arrangement ensures that the clamping force of the two rollers on the balloon is evenly distributed, preventing the balloon from shifting to one side, and making the breaking process more stable and smooth.

[0015] The present invention also provides a control method for a weather balloon disposal device, which, using the above-described weather balloon disposal device, includes the following steps: Upon receiving the balloon disposal instruction, the inflation solenoid valve is closed, the degassing solenoid valve is opened, and the degassing machine is started to pre-extract the hydrogen from the inside of the weather balloon. After the pre-extraction and discharge is set for a certain time, the first drive source and the second drive source are controlled to extend synchronously, driving the two sets of connecting rod assemblies to close in the middle until the two rollers abut and clamp the weather balloon. The third drive source is activated, which drives the two rollers to rotate in opposite directions synchronously through the meshing transmission gears. The raised structure on the rollers squeezes and breaks the weather balloon, so that the broken balloon debris falls into the storage box below. After confirming that the weather balloon has completely broken up, stop the third drive source, control the first and second drive sources to retract synchronously, and drive the two sets of linkage assemblies to open and reset to both sides; The control and transfer component moves the storage box to the sealed door position. After the sealed door is opened, the transfer mechanism retrieves the storage box back to the storage room, closes the sealed door, and completes the entire balloon disposal process. Its beneficial effects are as follows: This control method can realize the fully automated operation of balloon handling under abnormal working conditions without human intervention. It is especially suitable for fully automated upper-air meteorological detection systems deployed in remote areas and unattended sites, which greatly reduces the time and economic cost of manual operation and maintenance. The process logic of "first evacuate, then break up, and then reset" minimizes hydrogen and reduces the risk of hydrogen leakage. After the handling is completed, the system can be directly restored to the ready state and can carry out the next balloon release task without additional inspection and cleaning, thus improving the continuous operation capability of the system.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1 As shown, the weather balloon handling device of this embodiment is integrated and installed inside the balloon launch tube of the fully automatic upper-air meteorological detection system. It includes a conveying component 100, a symmetrically arranged first link assembly 400 and second link assembly 500, a first roller 600, a second roller 700, a first drive source 800, a second drive source 900, and a third drive source 1000. The conveying assembly 100 adopts a linear drive module and is arranged along the length of the balloon release tube. The storage box 200 is supported on its sliding table. The storage box 200 is normally used to hold the radiosonde and is used to receive the debris of the broken weather balloon 300 during disposal. The conveying assembly 100 can drive the storage box 200 to move back and forth between the position directly below the first roller 600 and the second roller 700 and the position of the sealed door between the balloon release tube and the storage chamber. The first linkage assembly 400 and the second linkage assembly 500 are symmetrically spaced along a first horizontal direction perpendicular to the conveying direction of the conveying assembly 100, and are located on the left and right sides of the inflation position of the weather balloon 300, respectively. The fixed ends of both are installed on the inner wall of the balloon release tube, and the movable ends are respectively installed with the first roller 600 and the second roller 700.

[0031] In this embodiment, as Figure 2 and Figure 4 As shown, the first linkage assembly 400 includes a first base 410, a first connecting rod 420, a second connecting rod 430, a first intermediate rod 440, and a first rotating shaft 450. The first base 410 is fixedly installed on the inner wall of one side of the ball discharge tube by bolts. The top of the first base 410 is hinged to one end of the first connecting rod 420 through a hinge shaft. The first connecting rod 420 is a straight rod structure, and its other end is hinged to one end of the second connecting rod 430 through a hinge shaft. The second connecting rod 430 is an L-shaped structure, and its corner position is fixedly connected to the first intermediate rod 440. The first intermediate rod 440 extends in a horizontal direction perpendicular to the first horizontal direction, and the output end of the first drive source 800 abuts against the rod body of the first intermediate rod 440. The second connecting rod 430 has a bearing mounting hole at its end away from the first connecting rod 420. A deep groove ball bearing is installed in the hole. The first rotating shaft 450 passes through the inner ring of the bearing and can rotate freely around its own axis. The outer circumferential surface of the first rotating shaft 450 is machined with at least one radially protruding first mating protrusion. In this embodiment, there are two first mating protrusions, which are evenly and symmetrically distributed along the circumference of the first rotating shaft 450.

[0032] Furthermore, the second linkage assembly 500 is structurally completely symmetrical to the first linkage assembly 400, including a second base 510, a third linkage 520, a fourth linkage 530, a second intermediate rod 540, and a second rotating shaft 550. The second base 510 is fixedly installed on the inner wall of the other side of the ball discharge tube by bolts. The top of the second base 510 is hinged to one end of the third linkage 520 via a hinge shaft. The third linkage 520 is a straight rod structure, and its other end is hinged to one end of the fourth linkage 530 via a hinge shaft. The fourth linkage 530 is an L-shaped structure, and its corner position is fixedly connected to the second intermediate rod 540. The second intermediate rod 540 is arranged parallel to the first intermediate rod 440, and the output end of the second drive source 900 abuts against the rod body of the second intermediate rod 540. The end of the fourth link 530 away from the third link 520 is also rotatably mounted with the second shaft 550 via a deep groove ball bearing. The outer circumferential surface of the second shaft 550 is machined with at least one second mating protrusion that protrudes radially. In this embodiment, there are two second mating protrusions that are evenly and symmetrically distributed along the circumference of the second shaft 550.

[0033] In this embodiment, both the first drive source 800 and the second drive source 900 are linear drive cylinders with synchronous operation. The cylinder bodies of the two cylinders are fixed on the inner wall of the ball discharge cylinder and are directly opposite the position of the middle rod on the corresponding side.

[0034] like Figure 4 As shown, when the output shafts of the two cylinders are in the retracted state, the first connecting rod 420 and the second connecting rod 430 are in an outward extended state, and the third connecting rod 520 and the fourth connecting rod 530 are in an outward extended state simultaneously. The first roller 600 and the second roller 700 are located on both sides of the weather balloon 300, with sufficient safety distance between them, so as not to interfere with the normal inflation operation of the weather balloon 300.

[0035] like Figure 5As shown, when the output shafts of the two cylinders extend synchronously, the output shafts push against the first intermediate rod 440 and the second intermediate rod 540, causing the first connecting rod 420 to rotate inward around the hinge point with the first base 410, the second connecting rod 430 to rotate inward around the hinge point with the first connecting rod 420, and simultaneously the third connecting rod 520 to rotate inward around the hinge point with the second base 510 and the fourth connecting rod 530 to rotate inward around the hinge point with the third connecting rod 520. Finally, the ends of the second connecting rod 430 and the fourth connecting rod 530 approach each other until the outer circumferential surfaces of the first roller 600 and the second roller 700 abut against each other, clamping the middle part of the weather balloon 300 between the two rollers.

[0036] In this embodiment, as Figure 2 and Figure 3 As shown, the first roller body 600 is a hollow cylindrical structure with a first mating groove on its inner wall that matches the first mating protrusion. The first roller body 600 is sleeved on the first rotating shaft 450, and the first mating protrusion is embedded in the first mating groove to form a circumferential engagement transmission, so that the first roller body 600 can rotate synchronously with the first rotating shaft 450 and can be disassembled axially. The first roller body 600 is divided axially into a first roller segment 610 and a second roller segment 620 of equal length. The outer circumferential surfaces of the first roller segment 610 and the second roller segment 620 are integrally machined with a spiral first protrusion, and the first protrusion on the first roller segment 610 and the first protrusion on the second roller segment 620 have opposite rotation directions: in this embodiment, viewed from the first axial end of the first roller body 600 towards the middle, the first protrusion on the first roller segment 610 is a left-handed helical tooth, and the first protrusion on the second roller segment 620 is a right-handed helical tooth.

[0037] Furthermore, the second roller body 700 is symmetrical to the first roller body 600 in structure and is also a hollow cylindrical structure. A second mating groove adapted to the second mating protrusion is opened on its inner wall. The second roller body 700 is sleeved on the second rotating shaft 550. The second mating protrusion is embedded in the second mating groove to form a circumferential engagement transmission, so that the second roller body 700 can rotate synchronously with the second rotating shaft 550.

[0038] The second roller body 700 is divided axially into a third roller segment 710 and a fourth roller segment 720 of equal length. The outer peripheral surfaces of the third roller segment 710 and the fourth roller segment 720 are integrally machined with a spiral second protrusion, and the second protrusion on the third roller segment 710 and the second protrusion on the fourth roller segment 720 have opposite directions of rotation. Viewed from the first axial end of the second roller 700 toward the middle, the second protrusion on the third roller section 710 is a right-handed helical tooth, and the second protrusion on the fourth roller section 720 is a left-handed helical tooth. Both the first and second protrusions adopt a meshing tooth structure. When the first roller body 600 and the second roller body 700 abut against each other, the teeth of the first and second protrusions mesh with each other, forming a continuous meshing area between the two roller bodies.

[0039] In this embodiment, the same end of the first roller 600 and the second roller 700 are both fixedly mounted with transmission gears of the same parameters by key connection, and the two transmission gears mesh with each other; the third drive source 1000 adopts a rotary drive motor, the motor housing is fixed on the end side wall of the second connecting rod 430, and the motor output shaft is coaxially fixedly connected to the end of the first rotating shaft 450 by a coupling.

[0040] When the third drive source 1000 is started, it drives the first rotating shaft 450 and the first roller 600 to rotate around their own axis. At the same time, through the transmission gears meshing at their ends, it drives the second rotating shaft 550 and the second roller 700 to rotate in opposite directions at the same speed. That is, the rotation direction of the first roller 600 and the second roller 700 is relative to each other and rotates inward, forming the working state of roller crushing.

[0041] The treatment device in this embodiment is also equipped with a hydrogen pipeline system, such as Figure 6 As shown, the hydrogen pipeline system includes an inflation branch, an exhaust branch, and an exhaust pump. One end of the inflation branch is connected to the hydrogen source, and the other end is connected to the inflation port of the weather balloon 300. An inflation solenoid valve is installed in series on the inflation branch. One end of the exhaust branch is connected to the inflation branch, with the connection point located between the inflation solenoid valve and the inflation port of the weather balloon 300. The other end of the exhaust branch is connected to the air inlet of the exhaust pump. The exhaust port of the exhaust pump extends through an exhaust pipe to a safe area outside the balloon launch tube. An exhaust solenoid valve is installed in series on the exhaust branch.

[0042] The specific working process and control principle of this embodiment are as follows: When the fully automatic upper-air meteorological detection system is performing the balloon release task normally, the output shafts of the first drive source 800 and the second drive source 900 are in the retracted state, the first linkage assembly 400 and the second linkage assembly 500 remain deployed, and the first roller 600 and the second roller 700 are far apart from each other, so as not to interfere with the inflation operation of the weather balloon 300. At this time, the inflation solenoid valve is open and the de-inflation solenoid valve is closed. Hydrogen is filled into the weather balloon 300 through the inflation branch. After inflation is completed, the normal release process is executed. After the release is completed, the conveyor assembly 100 drives the empty storage box 200 back to the sealed door position. The transfer robot grabs it and returns it to the storage room shelf, completing the system reset. When the system experiences abnormal conditions such as hydrogen leakage, balloon rupture, equipment failure, or temporary mission cancellation, and it is necessary to handle the already inflated weather balloon 300, the procedure should be as follows: Figure 7 The control flow shown executes the following actions: In the first step, after receiving the disposal command, the system first controls the inflation solenoid valve to close, cutting off the hydrogen supply path, and simultaneously controls the extraction solenoid valve to open, starting the extraction pump. At this time, the hydrogen inside the weather balloon 300 is discharged sequentially through the inflation port, the extraction branch, and the extraction pump to the outside of the balloon release tube. Since the internal and external pressure difference of the weather balloon 300 after normal inflation is 100~150Pa, the internal pressure of the balloon gradually decreases during the extraction process. When the internal pressure is lower than the external atmospheric pressure, the handle of the weather balloon 300 is compressed and sealed under the action of the external atmospheric pressure. At this time, the extraction pump can no longer extract the remaining hydrogen inside the balloon, but the remaining small amount of hydrogen can still support the weather balloon 300 to maintain an upright position and prevent it from falling over, ensuring that the subsequent clamping action can be executed normally.

[0043] The second step involves setting the pre-evacuation time. In this embodiment, the pre-evacuation time is set to 30 seconds, which can be adjusted according to the balloon specifications and hydrogen filling amount. The output shafts of the first drive source 800 and the second drive source 900 are controlled to extend synchronously, pushing against the first intermediate rod 440 and the second intermediate rod 540, driving the two sets of connecting rod assemblies to close synchronously towards the middle until the first roller 600 and the second roller 700 come into contact, clamping the upright meteorological balloon 300 in the interlocking area between the two rollers.

[0044] The third step involves starting the third drive source 1000, which drives the first roller 600 to rotate. Simultaneously, the transmission gears meshing at the ends drive the second roller 700 to rotate in the opposite direction at the same speed. During the rotation, the first protrusions on the first roller section 610 and the second roller section 620, which rotate in opposite directions, and the second protrusions on the third roller section 710 and the fourth roller section 720, which rotate in opposite directions, apply an axial force along the roller axis pointing towards the center to the surface of the contacted balloon. This causes the weather balloon 300, which is larger at the top and smaller at the bottom, to continuously converge towards the center of the roller, preventing the balloon from slipping out from both ends of the roller axis. At the same time, the meshing toothed protrusions apply continuous shearing and squeezing forces to the balloon skin, quickly tearing and crushing the weather balloon 300. The broken balloon debris falls downward under the rotational conveying action of the roller and falls directly into the storage box 200 directly below.

[0045] Fourth step: After the weather balloon 300 is completely broken by continuously rotating for a set time (exemplarily, in this embodiment, the breaking time is set to 10 seconds, which can be adjusted according to the balloon specifications), control the third drive source 1000 to stop rotating, and then control the output shafts of the first drive source 800 and the second drive source 900 to retract synchronously, driving the first link assembly 400 and the second link assembly 500 to rotate and unfold to both sides, returning to the initial open position.

[0046] Fifth, the control conveyor component 100 is activated, which moves the storage box 200 carrying the balloon debris along the straight module to the sealed door position between the balloon release tube and the storage chamber. The system controls the sealed door to open, and the transfer robot in the storage chamber grabs the storage box 200 and returns it to the storage chamber shelf. Then the sealed door closes, and the entire disposal device and detection system are restored to the initial ready state, ready to directly execute the next balloon release task.

[0047] In this embodiment, the connecting rod assembly adopts a double-bar hinged transmission structure, which provides smooth transmission and a large opening and closing stroke. The L-shaped end connecting rod ensures that the roller body is accurately aligned with the center of the balloon when it closes, while reducing the overall space occupied by the device. The roller body adopts a segmented reverse helical tooth structure, which ensures shearing and crushing capability through meshing teeth and solves the problem of irregularly shaped balloons easily slipping off the roller end through the axial gathering effect of the reverse helix. The single motor plus gear meshing drive method simplifies the transmission structure and reduces hardware costs and failure points. The process of first evacuating and then crushing can remove most of the hydrogen in the balloon, greatly reducing the risk of hydrogen leakage during the crushing process. All actions do not require manual on-site operation, making it particularly suitable for deployment in remote, unattended upper-air meteorological observation stations.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
