Description

Technical Field

[0001] This utility model relates to the field of upper-air meteorological detection technology, and in particular to a precision automatic air filling device for meteorological sounding. Background Technology

[0002] Meteorological sounding balloons are mainly used to carry radiosondes to high altitudes for detecting meteorological elements such as temperature, pressure, humidity, wind direction, and wind speed. In recent years, with the development of my country's BeiDou navigation-guided radiosonde system, the traditional single ascent phase observation is about to be upgraded to a three-phase observation of "ascent-drift-descent," meaning that three phases of radiosonde data can be obtained from a single observation. This will extend the spatial coverage and increase the temporal frequency of radiosonde observations, significantly improving the social benefits of radiosonde observations.

[0003] The upgraded "ascent-drift-descent" three-stage observation requires filling the double-layered weather balloon with hydrogen, and the net lift of the inner and outer balloons must be precise enough to enable the weather balloon to drift smoothly within the predetermined altitude range.

[0004] Upper-air meteorological stations still inflate double-layered weather balloons manually using traditional methods. This method is clearly insufficient to meet the required net lift accuracy, resulting in a less than satisfactory success rate for horizontal drift. Therefore, achieving precise control of the balloon's net lift during inflation is of significant research importance. Currently, there is no simple, effective, safe, and complete device for precisely controlling the net lift of double-layered weather balloons during inflation. Utility Model Content

[0005] In view of this, the present invention provides a precision automatic inflation device for meteorological sounding balloons, which can achieve precise control of the net lift force of the balloon during the inflation process of a horizontally drifting double-layer sounding balloon.

[0006] This utility model is achieved through the following technical solution: a refined automatic gas filling device for meteorological sounding, comprising a hydrogen storage tank, a hydrogen pipeline, a filling platform, a weighing sensor, a control box, an outer ball pipeline solenoid valve, an inner ball pipeline solenoid valve, an outer ball filling hose, and an inner ball filling hose; the hydrogen pipeline is divided into a front section and a rear section, the front section of which is connected to the hydrogen storage tank; the rear section of the hydrogen pipeline is divided into an outer ball filling pipeline and an inner ball filling pipeline, which are respectively connected to the double-sided gas filling platform via the outer ball filling hose and the inner ball filling hose. The outer and inner spheres of the sounding balloon are connected; the outer sphere inflation line is equipped with an outer sphere solenoid valve, and the inner sphere inflation line is equipped with an inner sphere solenoid valve; a load cell is fixed on the inflation platform and connected to the double-layer sounding balloon via a special sounding rope. The load cell is used to measure the net lift force and transmit the net lift force signal to the control box in real time; the control box is used to receive and display the net lift force, and to control the opening and closing of the outer and inner sphere solenoid valves in real time according to the magnitude of the net lift force.

[0007] Furthermore, the outer sphere inflation line is also equipped with an outer sphere inflation line fine-tuning valve to adjust the hydrogen flow rate in the outer sphere inflation line; the inner sphere inflation line is also equipped with an inner sphere inflation line fine-tuning valve to adjust the hydrogen flow rate in the inner sphere inflation line.

[0008] Furthermore, a hydrogen flow meter is installed at the front end of the hydrogen pipeline to measure the hydrogen flow rate through the hydrogen pipeline and transmit the hydrogen flow rate signal to the control box in real time. The control box is used to receive and display the hydrogen flow rate. The control box is also used to control the opening and closing degree of the fine adjustment valve of the outer ball pipeline and the fine adjustment valve of the inner ball pipeline to adjust the hydrogen flow rate in the outer ball filling pipeline and the inner ball filling pipeline.

[0009] Furthermore, a hydrogen detector is also provided to monitor the hydrogen concentration in the filling chamber and transmit the hydrogen concentration signal to the control box. The control box is also used to issue an alarm and close the solenoid valves of the outer and inner ball pipelines when the hydrogen concentration exceeds the set value.

[0010] Furthermore, the hydrogen pipeline is made of stainless steel, and a flame arrester is installed at the front end of the hydrogen pipeline.

[0013] 2. The control box of this utility model can adjust the fine-tuning valves of the outer ball pipeline and the inner ball pipeline according to the real-time changes in net lift force during the inflation process, so as to adjust the flow rate of hydrogen in the outer and inner balls and further refine the control of net lift force.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0018] This utility model provides a precision automatic inflation device for meteorological sounding, such as... Figure 1 As shown, the automatic inflation precision device includes a hydrogen storage tank 1, a hydrogen pipeline 2, an inflation platform 3, a double-layer weather balloon 4, a weighing sensor 5, a hydrogen meter 6, a control box 7, a flame arrester 8, a hydrogen flow meter 9, an outer balloon pipeline solenoid valve 11, an inner balloon pipeline solenoid valve 13, an outer balloon inflation hose 14, and an inner balloon inflation hose 15.

[0019] Hydrogen storage tank 1 stores a large amount of hydrogen gas. It is connected to a double-layered sounding balloon 4 via a hydrogen pipeline 2. The hydrogen pipeline 2 is made of stainless steel and consists of a front section and a rear section. The front section of the hydrogen pipeline 2 connects to the hydrogen storage tank 1 and is equipped with a flame arrester 8 and a hydrogen flow meter 9. The rear section of the hydrogen pipeline 2 is divided into two lines: an outer balloon filling pipeline and an inner balloon filling pipeline.

[0020] The outer sphere inflation line is connected to the outer sphere of the double-layered weather balloon 4 via the outer sphere inflation hose 14. An outer sphere inflation hose solenoid valve 11 is installed on the outer sphere inflation line. Hydrogen gas flows from the hydrogen storage tank 1 through the hydrogen pipeline 2, passing through the flame arrester 8, hydrogen flow meter 9, outer sphere inflation hose 11, and outer sphere inflation hose 14, and is transferred to the outer sphere of the double-layered weather balloon 4. The inner sphere inflation line is connected to the inner sphere of the double-layered weather balloon 4 via the inner sphere inflation hose 15. An inner sphere inflation hose solenoid valve 13 is installed on the inner sphere inflation line. Hydrogen gas flows from the hydrogen storage tank 1 through the hydrogen pipeline 2, passing through the flame arrester 8, hydrogen flow meter 9, inner sphere inflation hose 13, and inner sphere inflation hose 15, and is transferred to the inner sphere of the double-layered weather balloon 4. The outer sphere inflation hose 14 and the inner sphere inflation hose 15 can be made of flexible materials such as rubber or alloy spring steel.

[0021] The load cell 5 is fixed on the inflation platform 3 and connected to the double-layered sounding balloon 4 via a special sounding rope. The load cell 5 is a tension sensor with an accuracy of ±1g, used to measure the net lift force of the double-layered sounding balloon 4. The tension force measured by the load cell 5 is the difference between the buoyancy provided by the hydrogen gas inside the double-layered sounding balloon 4 and the weight of the double-layered sounding balloon 4 itself; this is the net lift force. The load cell 5 is electrically connected to the control box 7, transmitting the net lift force signal to the control box 7 in real time. The control box 7 can receive and display the magnitude of the net lift force in real time.

[0022] The flame arrester 8 prevents backfire from occurring in the hydrogen pipeline 2, which could lead to an explosion in the hydrogen storage tank 1. The hydrogen flow meter 9 measures the hydrogen flow rate through the hydrogen pipeline 2 and is electrically connected to the control box 7. The flow meter 9 transmits the hydrogen flow signal to the control box 7 in real time, and the control box 7 can receive and display the hydrogen flow rate information measured by the flow meter 9 in real time. Both the outer ball valve 11 and the inner ball valve 13 are electrically connected to the control box 7. The control box 7 can remotely control the opening and closing of the outer ball valve 11 and the inner ball valve 13 based on the received net lifting force. The hydrogen detector 6 is fixed in the filling chamber and electrically connected to the control box 7. It is used to remotely monitor for hydrogen leaks. If a hydrogen leak occurs (when the hydrogen concentration exceeds the set value), the control box 7 will issue an alarm and simultaneously close the outer ball valve 11 and the inner ball valve 13 as an emergency measure.

[0023] In addition, an outer ball inflation line is equipped with an outer ball inflation line fine-tuning valve 10, located upstream of the outer ball inflation line solenoid valve 11. The outer ball inflation line fine-tuning valve 10 is used to adjust the flow rate of hydrogen through the outer ball inflation line. Similarly, an inner ball inflation line fine-tuning valve 12 is located upstream of the inner ball inflation line solenoid valve 13. The inner ball inflation line fine-tuning valve 12 is used to adjust the flow rate of hydrogen through the inner ball inflation line. Both the outer and inner ball inflation line fine-tuning valves 10 and 12 are electrically connected to the control box 7. The control box 7 adjusts the opening degree of the outer and inner ball inflation line fine-tuning valves 10 and 12 based on the real-time changes in net lifting force during inflation, thereby adjusting the hydrogen flow rate in the outer and inner ball inflation lines. This allows for precise control of the net lifting force.

[0024] The outer ball pipeline fine-tuning valve 10 and the inner ball pipeline fine-tuning valve 12 can also be used for emergency handling. When a leak occurs in the transmission pipeline (hydrogen pipeline 2, outer ball inflation hose 14 or inner ball inflation hose 15), the outer ball pipeline fine-tuning valve 10 and the inner ball pipeline fine-tuning valve 12 can be closed for emergency handling.

[0025] This invention obtains the net lifting force by acquiring real-time signals from the weighing sensor 5 through the control box 7. The built-in program controls the opening and closing of the outer ball valve 11 and the inner ball valve 13, achieving precise control of the hydrogen volume inside the double-layered sounding balloon 4, thus controlling the net lifting force. The control box 7's fast and real-time processing capabilities ensure the high precision, stability, and reliability of the inflation device.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
