Description

Technical Field

[0001] The utility model relates to the field of meteorological sounding, in particular to a meteorological sounding self-destruction device. Background Art

[0002] Meteorological sounding has developed meteorological observation from two-dimensional space to three-dimensional space, revealing the relationship between the ground pressure system and the high-altitude air flow. The temperature, humidity, air pressure and other data at various altitudes in the atmosphere are of great significance for analyzing and studying various thermal and dynamic forces in the atmosphere, as well as weather analysis and forecasting.

[0003] The sounding technology generally used in my country is the "ground radar + sonde" mode, which can be simply divided into four steps: sonde launch, radar positioning, observation, and data transmission back to the radar. The launch of a radiosonde is generally carried out by launching a sounding balloon. The sonde carries air pressure, temperature and humidity sensors. After the sounding balloon is launched, it collects air pressure, temperature and humidity data and sends the data information to the ground radar. In addition, after the sounding balloon is launched, the ground radar tracks the sonde and can measure the straight-line distance, azimuth and elevation of the sonde from the radar at each moment, thereby obtaining the position of the sounding balloon in space. At the same time, based on the position of the sounding balloon in space at each moment, the wind direction and wind speed at high altitude can be calculated.

[0004] But from the above we also know that after the sounding balloon is launched, it will fly with the wind, so it is easy to fly into the airspace of other countries. In recent years, there have been many cases of unidentified balloons appearing in the sky over my country. my country's balloons may also drift into the sky over foreign countries. Such randomly flying sounding balloons are also likely to affect the aircraft in the sky. Utility Model Content

[0005] The utility model aims at the deficiencies in the prior art and provides a meteorological sounding self-destruction device which has a simple structure and a reasonable design and can burn relevant components and the sounding balloon once receiving a command, thereby avoiding the balloon from flying out of the working area.

[0006] In order to achieve the above-mentioned object, the utility model provides a meteorological sounding self-destruction device, including a ignition mechanism, wherein the ignition mechanism is arranged at the opening end of the sounding balloon;

[0007] The ignition mechanism comprises a heating wire and a volatile fuel, the heating wire is electrically connected to a relay and a first battery pack, the first battery pack is electrically connected to the relay, and the relay is electrically connected to a circuit board;

[0008] The circuit board is electrically connected to a second battery pack, and the circuit board is also electrically connected to a sensor;

[0009] The ignition mechanism comprises a fuel box, the fuel box is a cylindrical structure, the fuel box is connected to a box cover, and the box cover is screwed to the fuel box;

[0010] A variable diameter cylinder is provided at the screw connection between the box cover and the fuel box, the outer diameter of the variable diameter cylinder gradually decreases downward, and a variable diameter external thread is provided at the bottom of the variable diameter cylinder;

[0011] The top shape of the fuel box matches the variable diameter cylinder;

[0012] The fuel is placed in the fuel box;

[0013] The heating wire is arranged in the inner cavity of the fuel box and contacts the fuel. The heating wire is connected with a wire, and the wire passes through the side wall of the fuel box and is connected with the relay.

[0014] Furthermore, the heating wire is electrically connected to the NO terminal of the relay, and the first battery pack is electrically connected to the COM terminal of the relay;

[0015] The circuit board D5 terminal is electrically connected to the relay IN terminal.

[0016] Furthermore, the GND terminal of the relay is electrically connected to the G terminal of the circuit board, and the VCC terminal of the relay is electrically connected to the 3V terminal of the relay.

[0017] Furthermore, the circuit board D1 end is electrically connected to the sensor SCL end, and the circuit board D2 end is electrically connected to the relay SDA end.

[0018] Further, the GND terminal of the sensor is electrically connected to the G terminal of the circuit board, and the VCC terminal of the sensor is electrically connected to the 3V terminal of the circuit board.

[0019] Furthermore, the fuel box is made of plastic, and the box cover is made of aluminum alloy.

[0020] Furthermore, the fuel is a smokeless and environmentally friendly solid alcohol block.

[0021] Furthermore, the heating wire is made of nickel-chromium electric heating alloy.

[0022] Furthermore, the relay is a time-delay relay.

[0023] When the sounding balloon is working normally, the heating wire does not work because the heating wire is electrically connected to the NO terminal of the relay, which is also the normally open terminal.

[0024] When the self-destruct command is sent from the circuit board to the relay, that is, power is supplied between D5 of the circuit board and the IN terminal of the relay, the relay closes the loop between the first battery pack and the heating wire, and the heating wire heats up.

[0025] The heated heating wire accelerates the volatilization of solid alcohol. Due to the special threaded connection structure between the box cover and the fuel box, and the fuel box is made of plastic and the box cover is made of aluminum alloy, when the alcohol gas pressure in the fuel box reaches a certain level, the box cover will fly off.

[0026] At this time, the accumulated alcohol gas comes into contact with the atmosphere and burns violently. Coupled with the continued volatilization and burning of the solid alcohol, it burns related components and the opening of the sounding balloon, causing the sounding balloon to burn and fall.

[0027] The beneficial effects of this solution can be known from the description of the above solution. It has a simple structure and a reasonable design. Once the command is received, the relevant components and the sounding balloon will be burned, thus avoiding flying out of the working area. The mode of using electric heating wire and solid alcohol for ignition is because solid alcohol has little pollution to the environment; secondly, when solid alcohol evaporates, it can expand the closed container containing fuel, eliminating the need to set up an active opening mechanism specifically for opening the fuel container. At the rotating structure of the variable diameter cylinder of the box cover, the outer diameter decreases from top to bottom, and the outer thread at the end of the variable diameter cylinder also decreases from top to bottom. In this way, when tightening the box cover and the fuel box, the fuel box can be sealed; and when the internal air pressure increases and the box cover collapses, once the box cover and the fuel box are relatively separated, there will be no dragging and can be separated completely, so that the box cover will not block the air from entering the fuel box, nor will it block the flame from emitting surrounding objects.

[0033] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0034] like Figure 1-4 As shown, this embodiment is a meteorological sounding self-destruction device, comprising a fire ignition mechanism 1, which is arranged at the opening end of a sounding balloon 2;

[0035] The ignition mechanism 1 includes a heating wire 3 and a volatile fuel 12, the heating wire 3 is electrically connected to a relay 4 and a first battery pack 5, the first battery pack 5 is electrically connected to the relay 4, and the relay 4 is electrically connected to a circuit board 6;

[0038] A reducing cylinder 11 is provided at the screw connection between the box cover 10 and the fuel box 9. The outer diameter of the reducing cylinder 11 gradually decreases downwards, and a reducing external thread is provided at the bottom of the reducing cylinder 11.

[0039] The top shape of the fuel box 9 matches the variable diameter cylinder 11;

[0040] The fuel 12 is placed in the fuel box 9;

[0041] The heating wire 3 is disposed in the inner cavity of the fuel box 9 and contacts the fuel 12 . The heating wire 3 is connected with a wire 13 . The wire 13 passes through the side wall of the fuel box 9 and is connected with the relay 4 .

[0042] Further, the heating wire 3 is electrically connected to the NO terminal of the relay 4, and the first battery pack 5 is electrically connected to the COM terminal of the relay 4;

[0043] The D5 terminal of the circuit board 6 is electrically connected to the IN terminal of the relay 4 .

[0044] Further, the GND terminal of the relay 4 is electrically connected to the G terminal of the circuit board 6 , and the VCC terminal of the relay 4 is electrically connected to the 3V terminal of the relay 4 .

[0045] Further, the D1 end of the circuit board 6 is electrically connected to the SCL end of the sensor 8 , and the D2 end of the circuit board 6 is electrically connected to the SDA end of the relay 4 .

[0046] Further, the GND terminal of the sensor 8 is electrically connected to the G terminal of the circuit board 6 , and the VCC terminal of the sensor 8 is electrically connected to the 3V terminal of the circuit board 6 .
