[0074] A roller 16 that slidably contacts the side surface of the adjusting block 15. The roller 16 is fixedly installed on the support shaft 21;

[0075] And a linkage rod 20. Four groups of the linkage rods 20 are provided, and through holes for rotatably connecting with the support shaft 21 are opened at both ends of each group of the linkage rods 20. The four groups of the linkage rods 20 are distributed on both sides of the adjusting block 15 in pairs. Among them, the four groups of the linkage rods 20 form a parallelogram structure;

[0076] The clamping assembly includes:

[0077] A translation frame 5. The translation frame 5 is fixedly installed on the horizontally arranged moving frame 17;

[0078] A limiting groove 23. The limiting groove 23 is opened on the side wall of the air duct 12;

[0079] And a clamping plate 14 for pressing into the limiting groove 23 to fix the air duct 12. The clamping plate 14 is slidably installed on the top of the translation frame 5, and a third spring 34 for elastically supporting the clamping plate 14 is also provided in the translation frame 5;

[0080] The inflation assembly includes:

[0081] An air storage tank 2 fixedly installed in the support frame 1. A filling port 3 is also provided on the air storage tank 2;

[0082] An inflation box 7 fixedly installed on the moving frame 17 at the end far from the air storage tank 2. The inflation box 7 has a cavity inside, and an air inlet 33 communicating with the cavity is opened on the side surface of the inflation box 7. The air inlet 33 is connected to the air storage tank 2 through a telescopic tube 8;

[0083] A cylindrical hole for accommodating the air duct 12. The cylindrical hole is opened on the top of the support frame 1, and a diversion hole for communicating the cylindrical hole with the cavity is also opened in the inflation box 7. A second sealing inclined surface 29 is provided in the diversion hole;

[0084] A second plugging block 30 for plugging the second sealing inclined surface 29. The second plugging block 30 is slidably installed in the inflation box 7, and a second spring 31 for elastically supporting the second plugging block 30 is also provided in the inflation box 7;

[0085] A limiting post 32 for limiting the second plugging block 30, the limiting post 32 is arranged in the cavity of the inflatable box 7;

[0086] And a pressure sensor 19 fixed in the support frame 1, the pressure sensor 19 is located below the inflatable box 7 on the side close to the gas storage tank 2;

[0087] A strip hole for the telescopic tube 8 to penetrate is opened at the top of the support frame 1.

[0088] In this embodiment, an electromagnetic valve is arranged between the telescopic tube 8 and the gas storage tank 2. When the pressure sensor 19 detects the pressing force exerted on it by the moving frame 17, the electromagnetic valve opens, and vice versa, the electromagnetic valve closes. The electromagnetic valve and the pressure sensor 19 can both adopt existing public technologies. A module for transmitting data is also arranged at the bottom of the bottom plate 10, etc., which can all adopt existing public technologies and will not be specifically limited here; it is convenient to supplement gas into the gas storage tank 2 through the injection port 3. After the air duct 12 is placed in the fixed area above the support frame 1, the first motor 9 will drive the rotating shaft 18 to rotate, and rotate the adjusting block 15 to the position as shown in the attachment Figure 6 At this time, the moving frame 17 will pull the two translation frames 5 closer to each other. The translation frame 5 can drive the clamping plate 14 to press into the limiting groove 23 to fix the air duct 12. At the same time, the moving frame 17 at the top will push the inflatable box 7 upward. Before the third spring 34 is compressed, the inflatable box 7 has not yet moved to the highest position. As the inflatable box 7 moves further upward, the third spring 34 will be compressed, which can increase the pressing force of the clamping plate 14 on the air duct 12, thereby improving the fixing effect. When the inflatable box 7 is sleeved on the bottom of the air duct 12, the push rod 28 will extend into the inflatable box 7 and push the second plugging block 30 to press the second spring 31. When the second plugging block 30 moves onto the limiting post 32, the reaction force of the limiting post 32 will cause the first plugging block 26 to press the guide rod 25, realizing the separation of the first plugging block 26 from the first sealing inclined surface 27 and the separation of the second plugging block 30 from the second sealing inclined surface 29, thereby realizing the connection between the air duct 12 and the inflatable box 7. The moving frame 17 at the bottom will press on the pressure sensor 19, so that the gas in the gas storage tank 2 can enter the inflatable box 7 through the telescopic tube 8, and then be filled into the balloon body 6 through the air duct 12. After inflation is completed, both the translation frame 5 and the inflatable box 7 will reset. Under the buoyancy of the balloon body 6, the air duct 12 is pulled to separate from the inflatable box 7. The first spring 24 will push the first plugging block 26 to press onto the first sealing inclined surface 27 again to complete the sealing. At the same time, the second plugging block 30 will press onto the second sealing inclined surface 29 to reduce the leakage of gas in the inflatable box 7 and the telescopic tube 8, which is convenient for cost saving. After the moving frame 17 at the bottom contacts the pressure sensor 19, the electromagnetic valve closes in time to further reduce gas leakage.

[0089] In one embodiment of the present invention, refer to Figures 1-12 , further comprising a guide frame 13 for supporting the air duct 12, and a multi-stage lifting assembly for controlling the working position of the guide frame 13 is arranged on the support frame 1;

[0090] A circular hole slidably matched with the air duct 12 is formed in the guide frame 13;

[0091] The multi-stage lifting assembly includes:

[0092] A housing 4 fixedly installed on the support frame 1, an upper lifting box 35 is slidably installed in the housing 4, and a lower lifting box 36 is slidably installed in the upper lifting box 35;

[0093] An upper and lower lifting box 37 fixedly connected to the guide frame 13, and the upper and lower lifting box 37 is slidably installed in the lower lifting box 36;

[0094] A motor two 39 arranged in the housing 4, the output end of the motor two 39 is connected with a threaded rod 38, an internal threaded hole threadedly connected with the threaded rod 38 is formed at the bottom of the upper lifting box 35, and holes for the threaded rod 38 to penetrate through are formed at the bottoms of the lower lifting box 36 and the upper and lower lifting box 37;

[0095] A gear one 41 rotatably installed on the side wall of the upper lifting box 35, and racks one 40 meshing with the gear one 41 are arranged on the side walls of the housing 4 and the lower lifting box 36;

[0096] And a gear two 42 rotatably installed on the side wall of the lower lifting box 36, and racks two 43 meshing with the gear two 42 are arranged on the side walls of the upper lifting box 35 and the upper and lower lifting box 37.

[0097] In this embodiment, by the supporting effect of the bottom plate 10, it is convenient for the staff to place the collection mechanism on the top of the support frame 1; the motor two 39 can make the upper lifting box 35 move up or down in the housing 4 by driving the threaded rod 38 to rotate. When the upper lifting box 35 moves up, the upper lifting box 35 will drive the gear one 41 to move up synchronously. Since the position of the housing 4 is fixed, the rack one 40 on the housing 4 can make the gear one 41 rotate counterclockwise (the counterclockwise direction refers to the appendix Figure 12), the counterclockwise rotating gear one 41 will drive the rack one 40 on the lifting box two 36 to move upward, thereby driving the lifting box two 36 to move upward. When the lifting box two 36 drives the gear two 42 to move upward synchronously, during the upward movement of the gear two 42, through the meshing action with the rack two 43 on the lifting box one 35, it will rotate counterclockwise, thereby driving the rack two 43 on the lifting box three 37 to move upward, and then driving the lifting box three 37 to move upward. The multi-stage lifting effectively expands the moving range. Thus, after the inflation is completed, the lifting box three 37 will drive the air guide pipe 12 to move upward by means of the guide frame 13, thereby stably pushing the balloon body 6 upward, and further improving the stability of the balloon body 6 when rising. The multi-stage lifting method can achieve the maximum displacement guiding effect in a limited space and improve the success rate of releasing the balloon body 6.

[0098] In summary, the working principle of the present invention is as follows: When in use, first carry the release mechanism to the working area, and then place the balloon body 6 to be released above the support frame 1 (at this time, the staff can stay away from the working area and remotely control the working state of the synchronous drive assembly). The synchronous drive assembly works by driving the clamping assembly and the inflation assembly. The clamping assembly can fix the self-locking receiving assembly, and at the same time, the inflation assembly will be docked with the self-locking receiving assembly to fill the balloon body 6 with gas. After the balloon body 6 is filled with gas, the synchronous drive assembly will reset the clamping assembly and the inflation assembly, and use the self-locking receiving assembly to seal the balloon body 6. At this time, the self-locking receiving assembly that gets rid of the clamping assembly will rise into the air following the buoyancy of the balloon body 6, and the meteorological data can be collected by using the sensor module 11, effectively ensuring the personal safety of the staff and improving the safety performance of the device; specifically: With the support of the bottom plate 10, it is convenient for the staff to place the collection mechanism on the top of the support frame 1; With the injection port 3, it is convenient to supplement gas into the gas storage tank 2. After the air guide pipe 12 is placed in the fixed area above the support frame 1, the motor one 9 will drive the rotating shaft 18 to rotate and turn the adjusting block 15 to the attachment Figure 6At the shown position, the moving frame 17 will pull the two translation frames 5 closer to each other at this time. By using the translation frame 5, the clamping plate 14 can be driven to press into the limit groove 23, so as to fix the air duct 12. At the same time, the moving frame 17 at the top will push the inflation box 7 upward. Before the third spring 34 is compressed, the inflation box 7 has not yet moved to the highest position. As the inflation box 7 moves further upward, the third spring 34 will be compressed, which can increase the pressing force of the clamping plate 14 on the air duct 12, thereby improving the fixing effect. When the inflation box 7 is sleeved on the bottom of the air duct 12, the push rod 28 will extend into the inflation box 7 and push the second plugging block 30 to press the second spring 31. When the second plugging block 30 moves onto the limit post 32, the reverse acting force of the limit post 32 will cause the first plugging block 26 to press the guide rod 25, so as to separate the first plugging block 26 from the first sealing inclined surface 27 and the second plugging block 30 from the second sealing inclined surface 29, thereby connecting the air duct 12 and the inflation box 7. The moving frame 17 at the bottom will press on the pressure sensor 19, so that the gas in the gas storage tank 2 can enter the inflation box 7 through the telescopic pipe 8, and then be filled into the balloon body 6 through the air duct 12. After inflation is completed, both the translation frame 5 and the inflation box 7 will reset. Under the buoyancy of the balloon body 6, the air duct 12 is pulled to separate from the inflation box 7, and the first spring 24 will push the first plugging block 26 to press onto the first sealing inclined surface 27 again to complete the sealing. At the same time, the second plugging block 30 will press onto the second sealing inclined surface 29 to reduce the leakage of gas in the inflation box 7 and the telescopic pipe 8, which is convenient for cost saving. After the moving frame 17 at the bottom is in contact with the pressure sensor 19, the solenoid valve will be closed in time to further reduce gas leakage; the second motor 39 can drive the lifting box 35 to move up or down in the outer housing 4 by driving the threaded rod 38 to rotate. When the lifting box 35 moves upward, the lifting box 35 will drive the first gear 41 to move upward synchronously. Since the position of the outer housing 4 is fixed, the first gear 41 can be rotated counterclockwise by using the first rack 40 on the outer housing 4 (the counterclockwise direction refers to the appendix Figure 12 ), the counterclockwise rotating first gear 41 will drive the first rack 40 on the second lifting box 36 to move upward, thereby driving the second lifting box 36 to move upward. When the second lifting box 36 drives the second gear 42 to move upward synchronously, during the upward movement of the second gear 42, through the meshing action with the second rack 43 on the first lifting box 35, it will rotate counterclockwise, thereby driving the second rack 43 on the third lifting box 37 to move upward, and then driving the third lifting box 37 to move upward. The multi-stage lifting effectively expands the moving range. Therefore, after inflation is completed, the third lifting box 37 will drive the air duct 12 to move upward by using the guiding frame 13, so as to stably push the balloon body 6 upward, thereby improving the stability of the balloon body 6 when rising. The multi-stage lifting method can achieve the maximum displacement guiding effect in a limited space and improve the success rate of flying the balloon body 6.
