A self-balancing sounding balloon and its inflation method

Abstract

The invention relates to a self-balancing sounding balloon and an air inflation method thereof. The self-balancing sounding balloon comprises a gasbag, a base, a pressure limiting mechanism, a pressure relief module and a guiding module, and the pressure limiting mechanism is arranged on the gasbag through the base; the pressure limiting mechanism comprises pressure relief shells and pressure relief pistons, and the closed ends of the pressure relief shells are communicated with the inner space of the gasbag; the opening ends of the pressure relief shells are provided with ring-shaped protrusions, and the pressure relief pistons are connected with the ring-shaped protrusions through extension springs; a plurality of through-holes B are formed on the axial middle wall of the pressure relief shells, and a plurality of pressure discharging holes are formed on a pressure discharging cavity; the pressure relief pistons are rotatably connected with connecting jaws, an air discharging nozzle is arranged at the bottom of the pressure discharging cavity, the air discharging nozzle comprises an air discharging piston rod, and the air discharging piston rod is flexibly connected with a fixing seat through a cardan shaft; the guiding module comprises cone-shaped guiding heads and stabilizing rings, the connecting jaws are rotatably connected with the stabilizing rings, the guiding heads are fixed on the stabilizing rings, and a plurality of guiding air plates with the quantity corresponding to the quantity of the connecting jaws are arranged on one side the guiding head, which backs onto the gasbag.

Description

technical field [0001] The invention relates to a self-balancing sounding balloon and an inflation method thereof, belonging to the field of meteorological equipment. Background technique [0002] High-altitude meteorological detection is to collect high-altitude meteorological data through the radiosonde carried by the sounding balloon, and the sounding balloon uses hydrogen or helium as the filling gas; [0003] In addition to one meteorological station in Hong Kong (the AUTOSONDE system imported from Finnish vaisala company), all high-altitude meteorological detection side stations and sounding balloons are manually operated. In the world, only a few developed countries such as Europe and the United States are equipped with unmanned high-altitude weather detection stations. So far, Finland is the only country that can develop an automatic balloon filling and deflation device for atmospheric detection. To realize unmanned high-altitude meteorological detection, the first...

Problems solved by technology

[0007] A recyclable sounding balloon is mentioned in ZL201220732719.0. Its recovery is mainly controlled by a thin rope to control its range of motion. Although the height of the sounding balloon can be well limited by the thin rope, it also greatly limits the detection capacity of the sounding balloon. The activity space of the air balloon, and the string itself is relatively easy to break or entangle, and it is easy to lose the sounding balloon and related electronic equipment;

[0008] ZL200920044465.1 proposes a set of automatic recovery, automatic inflation, and automatic emptying of the sounding balloon, although compared with the sounding balloon in the previous patent literature, it cancels the string component and enlarges the activity space of the sounding balloon At the same time, the air pressure of some balloons and the cooperation of guiding drive equipment and sensors have improved the control ability of the sounding balloon, but the mass of the electronic equipment itself is relatively large, which will bring a certain test to the load capacity of the sounding balloon. The temperature is relatively low, so it is difficult to guarantee whether these sensors can work normally. Once the sensor fails, it will still lead to the loss of control, loss or loss of the sounding balloon, which will bring a certain maintenance burden to the observation station
