[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] like Figures 1 to 3 As shown, a sounding balloon blasting device is arranged inside or outside the balloon body 1, and the device includes an explosive 6, a heating element 4, a battery 4 and a control board 5.
[0026] The explosive 6 is located close to the balloon body 1 and is configured to explode after being heated.
[0027] The heating element 8 is in contact with the explosive 6 and is used to heat the explosive 6 .
[0028] The battery 4 is used to supply power to the heating element 8 to increase the temperature of the heating element 8.
[0029] The control board 5 is used to change the temperature state of the heating element 8 by controlling the power supply state of the battery 4.
[0030] In the process of using a sounding balloon for meteorological detection, first, the blasting device is fixed. If the amount of explosive 6 used is large, the blasting device can be fixed on the outside of the balloon body 1. If the amount of explosive 6 used is small, the blasting device can be fixed on the inside of the balloon body 1. Obviously, it is easier to fix the blasting device on the outside of the balloon body 1. After the blasting device is fixed, the meteorological detection device is fixed on the suspension rope 3 connected to the balloon body 1. It should be noted that the meteorological detection device belongs to the existing technology in this field and has nothing to do with the technical problem to be solved by the present utility model. Those skilled in the art can flexibly select appropriate gas phase detection devices according to actual needs and set them on the suspension rope 3. Then, the sounding balloon is launched. When the sounding balloon rises to a certain height, the control board 5 controls the battery 4 to supply power to the heating element 8. After the heating element 8 is energized, it generates heat to increase its own temperature. When the temperature of the heating element 8 reaches a certain level, the explosive 6 is detonated. If the blasting device is set outside the balloon body 1, the shock wave generated when the explosive 6 explodes can break through the balloon body 1, thereby achieving the purpose of exploding the balloon body 1. If the blasting device is set inside the balloon body 1, the large amount of gas generated when the explosive 6 explodes can burst the balloon body 1, thereby achieving the purpose of exploding the balloon body 1.
[0031] The utility model can actively explode the sounding balloon by heating and detonating the explosive 6, thereby preventing the sounding balloon from causing adverse effects on high-altitude flight equipment.
[0032] like Figure 3 As shown, to precisely control the explosion time and location of the balloon body 1, the control panel 5 includes a timing module and a main control module. The timing module is used to record the flight duration of the balloon body 1 and output a trigger signal when the flight duration reaches a preset duration threshold. Upon receiving the trigger signal, the main control module controls the battery 4 to supply power to the heater 8. When the sounding balloon is launched, the timing module is activated and begins timing. Since the buoyancy of the balloon body 1 in air after being filled with argon gas can be calculated, its ascent speed can also be determined. Combined with the timing results from the timing module, the ascent height of the balloon body 1 can be calculated. When the flight duration of the balloon body 1 reaches the preset duration threshold, indicating that the balloon body 1 has reached the expected altitude range, the timing module sends a trigger signal to the main control module. Based on the trigger signal, the main control module controls the battery 4 to supply power to the heater 8. The temperature of the heater 8 continues to rise, ultimately detonating the explosive 6 and causing the balloon body 1 to explode.
[0033] The timing module's specific structure is as follows: the timing module includes a timing chip U2 electrically connected to a battery 4. Timing chip U2 is also electrically connected to a potentiometer R4 for controlling the duration threshold and a transistor Q1 for outputting a trigger signal. A switch S1 is connected between timing chip U2 and battery 4. The main control module includes a main control chip U1, whose signal input pin is electrically connected to the three pins of transistor Q1, and one of its output pins is electrically connected to a heater 8. When launching a sounding balloon, potentiometer R4 is first adjusted according to the desired altitude range, and then switch S1 is pressed to turn on the timing module. When the flight time of the balloon body 1 reaches the preset time threshold, pin 1 of the timing chip U2 outputs a high level, the base of the transistor Q1 is at a high level, the collector and emitter of the transistor are turned on, and pin 3 of the transistor Q1 becomes a low level. The level change of pin 3 of the transistor Q1 can generate a trigger signal. After the main control chip U1 receives the trigger signal, that is, pin 7 of the main control chip U1 senses that the level of pin 3 of the transistor Q1 becomes a low level, pin 1 of the main control chip U1 outputs current to the heating element 8, causing the temperature of the heating element 8 to rise until the explosive 6 is detonated.
[0034] In one embodiment of the present invention, the device of the present invention is arranged outside the balloon body 1, the distance between the explosive 6 and the air inlet 2 of the balloon body 1 is 45 to 55 cm, and the heating element 8 is filamentous and wrapped around the explosive 6.
[0035] like Figure 2As shown, in another embodiment of the present invention, the device is disposed within the balloon body 1. The heater 8 is plate-shaped and fixed to the explosive 6. A stinger 10 is fixedly connected to the side of the heater 8 facing away from the explosive 6. When the heater 8 detonates the explosive 6, the shock wave generated by the explosion impacts the heater 8, causing it to move. This in turn drives the stinger 10 to move synchronously. When the stinger 8 contacts the balloon body 1, it punctures the balloon body 1. When the heater 8 contacts the balloon body 1, it melts the balloon body 1. In this embodiment, the heater 8, stinger 10, and explosive 6 all function to detonate the balloon body 1, fully ensuring that the balloon body 1 can be actively ruptured.
[0036] The needle 10 is specifically arranged as follows: the heating element 8 is vertically fixedly connected to the connecting piece 9, the needle 10 is fixedly connected to the connecting piece 9, and the connecting piece 9 is connected to the control board 5 via an elastic connecting piece 7. The elastic connecting piece 7 is used to enable the heating element 8 to be driven by the shock wave. In this embodiment, the elastic connecting piece 7 is a spring.
[0037] In order to heat the thorn needle 10 and further ensure that the balloon body 1 can be exploded smoothly, the heating element 8, the connecting piece 9 and the thorn needle 10 are connected as one body, and the heating element 8, the connecting piece 9 and the thorn needle 10 can all be made of copper.
[0038] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
