Abstract
Description
Technical Field
[0001] The invention relates to the technical field of super-pressure balloon deflation self-destruction equipment, in particular to a super-pressure balloon deflation self-destruction device and a self-destruction method thereof. Background Art
[0002] The superpressure balloon has a relatively stable swing period during the launch process, and its shape and volume remain basically unchanged. Its wind measurement performance is independent of the launch altitude. It is currently mainly used for high-precision high-altitude wind field measurement, and can also be used to obtain real-time meteorological elements such as atmospheric temperature, humidity, pressure and wind field within a certain altitude range. It is the most important source of data for meteorological scientific research and support services, and also provides more accurate measured data of air meteorological elements for space launch trajectory high-altitude wind correction, measurement and control radio wave atmospheric refraction correction, error separation, meteorological (numerical) forecasting and meteorological scientific research.
[0003] The superpressure balloon is a non-inflated balloon. Its shape and volume remain basically unchanged during the launch. As the altitude increases, the atmospheric pressure continues to decrease, and the pressure difference between the inside and outside of the balloon continues to increase. When a certain pressure difference is reached, the balloon bursts and cannot fly to the predetermined altitude. Therefore, it is necessary to control the pressure difference between the inside and outside of the balloon to prevent it from bursting prematurely. At the same time, in order to prevent the buoyancy of the balloon from being balanced with the gravity of the balloon and its payload at a certain altitude, causing the balloon to float flat, which may affect airspace safety, it is necessary to design a self-destruct mechanism to allow the balloon to descend to the ground.
[0004] At present, the more mature way to deflate super-pressure balloons is natural deflation. By opening a deflation hole at the bottom of the self-destruct device installed at the handle of the balloon, the balloon is naturally deflated through the internal and external pressure difference during the release process. This deflation method has extremely precise requirements for the size of the deflation hole. Once there is an error in the size, it is easy to cause the super-pressure balloon to fail to reach the predetermined height, resulting in a low success rate for the flight of super-pressure balloons and inability to promote and use them in large quantities. At the same time, the current self-destruction method is pyrotechnic self-destruction blasting. Pyrotechnics are installed in the self-destruct device at the handle of the balloon. After reaching the predetermined height, the pyrotechnics are detonated to deflate and self-destruct the balloon. Due to my country's strict control over pyrotechnics, there are extremely strict processes and procedures for purchasing, transporting and using them, so they cannot be used in large quantities. In addition, most super-pressure balloons are filled with hydrogen, which can easily cause safety accidents if not operated properly.
[0005] In view of the above problems, it is extremely urgent to develop a superpressure balloon deflation self-destruction device and a self-destruction method thereof. Summary of the invention
[0006] In view of the shortcomings in the above-mentioned existing production technology, the applicant provides a super-pressure balloon deflation self-destruction device and a self-destruction method, thereby adding a double insurance mechanism of physical self-destruction and electric self-destruction while ensuring the normal ascent of the super-pressure balloon, ensuring that the super-pressure balloon self-destructs at a preset height and time, and is suitable for mass production and social promotion.
[0007] The technical solution adopted by the present invention is as follows: a superpressure balloon deflation self-destruction device, comprising a four-way shell connected to the superpressure balloon handle at the bottom of the superpressure balloon body, the air outlet of the superpressure balloon handle is connected to the upper passage of the four-way shell; a sealing hose is arranged on the left passage of the four-way shell, and a self-destruction ball pre-sealed with part of the gas is arranged in the sealing hose, and the self-destruction ball expands as the flight height of the superpressure balloon body increases; a pressure relief valve is arranged on the right passage of the four-way shell, and an electric control device is hung at the bottom of the four-way shell via a first hanging rope, and the first hanging rope is connected to the heating wire inside the electric control device; the electric control device is also connected to one end of a second hanging rope, and the other end of the second hanging rope is connected to the pressure relief valve.
[0008] As a further improvement of the above technical solution:
[0009] Preferably, the lower passage of the four-way shell is connected to an inflation nozzle, which is used to fill gas into the super-pressure balloon body, and a check valve is integrated inside the inflation nozzle to prevent gas leakage in the balloon.
[0010] Preferably, electric control device fixing rings are provided on both sides of the inflation nozzle, and the first hanging rope passes through the electric control device fixing rings and is connected to the heating wire inside the electric control device.
[0011] Preferably, the structure of the pressure relief valve is: it includes a silicone sheet, the silicone sheet is connected to a torsion spring, and the torsion spring provides a pre-pressure to the silicone sheet, and the pre-pressure pushes the silicone sheet to seal the right passage; as the atmospheric pressure difference between the inside and outside of the overpressure balloon body increases during the launch, the pressure relief valve opens to relieve pressure after overcoming the elastic force of the torsion spring, and the greater the pressure difference, the greater the valve opening angle, and after the pressure difference between the inside and outside of the overpressure balloon is balanced, the pressure relief valve closes.
[0012] Preferably, a through hole is provided on the top of the electric control device, and the second hanging rope is connected to the silicone sheet of the pressure relief valve after passing through the through hole on the top of the electric control device.
[0013] Preferably, the length of the second hanging rope is greater than the distance between the electronic control device and the pressure relief valve.
[0014] A super-pressure balloon deflation self-destruction method comprises the following steps:
[0015] Step 1: Given the ground pressure of the super-pressure balloon at the release point, the corresponding altitude pressure, and the volume of the self-destructing ball that breaks the sealing hose, the maximum inflation volume in the self-destructing ball on the ground can be calculated based on the gas expansion formula;
[0016] Step 2: Inflate the self-destruct ball using an inflation device according to the inflation volume of the self-destruct ball calculated in step 1;
[0017] Step 3: On the ground, pre-set the self-destruction height and self-destruction time parameters of the electronic control device through the configuration software;
[0018] Step 4: After the configuration of step 3 is completed, the upper passage of the four-way housing is installed and connected with the handle of the super-pressure balloon;
[0019] Step 5: Inflate the super-pressure balloon and release it after inflation is completed;
[0020] Step 6: The super-pressure balloon body continues to rise, and the self-destructing ball continues to expand during the flight. The super-pressure balloon body automatically deflates through the pressure relief valve according to the difference in atmospheric pressure inside and outside;
[0021] Step 7: When the super-pressure balloon body flies to the self-destruction altitude, the super-pressure balloon body undergoes physical self-destruction or electrical self-destruction.
[0022] Among them, in step six, the continuous rising process of the superpressure balloon body is: the atmospheric pressure difference inside and outside the superpressure balloon is greater than the preset value of the pressure relief valve, and the pressure relief valve opens to relieve pressure. The greater the atmospheric pressure difference inside and outside the superpressure balloon, the greater the valve opening angle. When the pressure difference inside and outside the superpressure balloon is balanced, the valve closes. During the automatic deflation of the pressure relief valve, the superpressure balloon body continues to rise.
[0023] Preferably, the physical self-destruction process in step seven is as follows:
[0024] The sealed hose uses heat sealing technology to press multiple layers of film together to form the hose body;
[0025] The membrane material used for the self-destructing ball should be stronger than the sealing hose;
[0026] During the ascent of the super-pressure balloon body, the external air pressure decreases and the self-destruction ball expands. When the expanded diameter of the self-destruction ball exceeds the diameter of the sealing hose, the pressure on the sealing hose increases. When the lateral pressure applied to the sealing hose due to the expansion of the self-destruction ball exceeds the tensile strength that the joint of the sealing hose can withstand, the joint of the sealing hose is squeezed and the gas filled in the super-pressure balloon body leaks from the left passage, and the balloon gradually descends to the ground and completes self-destruction.
[0027] Preferably, the electronically controlled self-destruction process in step seven is as follows:
[0028] When the super-pressure balloon reaches the set self-destruction height, the electric control device heats the internal heating wire, and the heating wire melts the first hanging rope; at this time, the second hanging rope connected to the electric control device changes from a relaxed state to a stretched state;
[0029] Since the other end of the second hanging rope is connected to the pressure relief valve, the second hanging rope transmits the gravity of the electronic control device as an external force to the pressure relief valve. The pressure relief valve is pulled by the second hanging rope and fully opened. The gas filled in the superpressure balloon body leaks from the right passage, and the superpressure balloon body gradually falls to the ground and completes self-destruction.
[0030] The beneficial effects of the present invention are as follows:
[0031] The present invention has a compact structure and is easy to assemble. A pressure relief valve is arranged on the right passage of a four-way shell connected to the handle of the superpressure balloon. The pressure relief valve provides a pre-pressure to the silicone sheet through a torsion spring, and the pre-pressure pushes the silicone sheet to seal the right passage. As the atmospheric pressure difference inside and outside the superpressure balloon body increases during the launch, the pressure relief valve opens to relieve pressure after overcoming the elastic force of the torsion spring. The greater the pressure difference, the greater the valve opening angle. After the pressure difference inside and outside the superpressure balloon is balanced, the pressure relief valve closes. The automatic deflation design can automatically control the pressure difference between the superpressure balloon and the external atmosphere within a certain range, so that the balloon can rise stably without bursting in advance, thereby greatly improving the flight success rate. In addition, the present invention adopts a self-destruction redundant design with a dual insurance mechanism of physical self-destruction and electrical control, which greatly improves the success rate of superpressure balloon self-destruction, reduces the impact of the superpressure balloon floating on airspace safety, and can eliminate the safety hazards to people caused by conventional self-destruction methods.

[0043] In this embodiment, the lower passage 304 of the four-way shell 3 is connected to the inflation nozzle 7, and the inflation nozzle 7 is used to fill gas into the superpressure balloon body 1. A check valve is integrated inside the inflation nozzle 7 to prevent gas leakage in the balloon.
[0044] In this embodiment, electric control device fixing rings 8 are provided on both sides of the inflation nozzle 7 , and the first hanging rope 11 passes through the electric control device fixing rings 8 and is connected to the electric heating wire 10 inside the electric control device 9 .
[0045] In this embodiment, the structure of the pressure relief valve 6 is: it includes a silicone sheet, the silicone sheet is connected to a torsion spring, the torsion spring provides a pre-pressure to the silicone sheet, and the pre-pressure pushes the silicone sheet to seal the right passage 303; as the atmospheric pressure difference inside and outside the overpressure balloon body 1 increases during the ascent, the pressure relief valve 6 opens to relieve pressure after overcoming the elastic force of the torsion spring, and the greater the pressure difference, the greater the valve opening angle. After the pressure difference inside and outside the overpressure balloon is balanced, the pressure relief valve 6 is closed.
[0046] In this embodiment, a through hole is provided on the top of the electric control device 9 , and the second hanging rope 12 passes through the through hole on the top of the electric control device 9 and is connected to the silicone sheet of the pressure relief valve 6 .
[0047] In this embodiment, the length of the second hanging rope 12 is greater than the distance between the electronic control device 9 and the pressure relief valve 6 .
[0048] The super-pressure balloon deflation self-destruction method of this embodiment comprises the following steps:
[0049] Step 1: Given the ground pressure of the super-pressure balloon body 1 at the release point, the corresponding altitude pressure, and the volume of the self-destructing ball 5 that breaks the sealing hose 4, the maximum inflation volume in the self-destructing ball 5 on the ground can be calculated according to the gas expansion formula;
[0050] Step 2: Inflate the self-destructing ball 5 through an inflation device according to the inflation amount of the self-destructing ball 5 calculated in step 1;
[0051] Step 3: On the ground, the self-destruction height and self-destruction time parameters are pre-set for the electronic control device 9 through the configuration software;
[0052] Step 4: After the configuration of step 3 is completed, the upper passage 301 of the four-way housing 3 is installed and connected with the super-pressure balloon handle 2;
[0053] Step 5: Inflate the super-pressure balloon body 1, and release it after the inflation is completed;
[0054] Step 6: The super-pressure balloon body 1 continues to rise, and the self-destructing ball 5 continues to expand during the flight, and the super-pressure balloon body 1 automatically deflates through the pressure relief valve 6 according to the difference in atmospheric pressure inside and outside;
[0055] Step 7: When the super-pressure balloon body 1 flies to the self-destruction altitude, the super-pressure balloon body 1 performs physical self-destruction or electrical self-destruction.
[0056] In step six, the continuous rising process of the superpressure balloon body 1 is: the atmospheric pressure difference inside and outside the superpressure balloon is greater than the preset value of the pressure relief valve 6, and the pressure relief valve 6 opens to relieve pressure. The greater the atmospheric pressure difference inside and outside the superpressure balloon, the greater the valve opening angle. When the pressure difference inside and outside the superpressure balloon is balanced, the valve closes. During the automatic deflation process of the pressure relief valve 6, the superpressure balloon body 1 continues to rise.
[0057] In this embodiment, specifically, the physical self-destruction process in step seven is as follows:
[0058] The sealing hose 4 uses heat sealing technology to press the multi-layer film together to form a hose body;
[0059] The strength of the membrane material used for the self-destructing ball 5 should be greater than that of the sealing hose 4;
[0060] During the ascent of the super-pressure balloon body 1, the external air pressure decreases and the self-destruction ball 5 expands. When the expanded diameter of the self-destruction ball 5 exceeds the diameter of the sealing hose 4, the pressure on the sealing hose 4 increases. When the lateral pressure applied to the sealing hose 4 due to the expansion of the self-destruction ball 5 exceeds the tensile strength that the joint of the sealing hose 4 can withstand, the joint of the sealing hose 4 is squeezed and the gas filled in the super-pressure balloon body 1 leaks from the left passage 302, and the balloon gradually descends to the ground, completing self-destruction.
[0061] In this embodiment, specifically, the electronically controlled self-destruction process in step seven is as follows:
[0062] When the super-pressure balloon body 1 reaches the set self-destruction height, the electric control device 9 energizes and heats the internal electric heating wire 10, and the electric heating wire 10 fuses the first hanging rope 11; at this time, the second hanging rope 12 connected to the electric control device 9 changes from a relaxed state to a stretched state;
[0063] Since the other end of the second hanging rope 12 is connected to the pressure relief valve 6, the second hanging rope 12 transmits the gravity of the electronic control device 9 as an external force to the pressure relief valve 6. The pressure relief valve 6 is pulled by the second hanging rope 12 and fully opened. The gas filled in the superpressure balloon body 1 leaks from the right passage 303, and the superpressure balloon body 1 gradually falls to the ground and completes self-destruction.
[0064] The present invention ensures the normal ascent of the super-pressure balloon through the automatic deflation design of the pressure relief valve 6, and at the same time adds a double insurance mechanism of physical self-destruction and electric self-destruction. Under the condition of ensuring the personal safety of the operator, it ensures that the super-pressure balloon self-destructs at a preset height and time. The whole device is simple in design and easy to operate. It can be operated by one person and is suitable for mass production and popularization.

To make the description concise, not all possible combinations of the technical features in the above-described 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.
[0066] The above-mentioned embodiments only express the implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
