Directional exhaust type constant-pressure sounding balloon and air inflation method thereof

Abstract

The invention relates to a directional exhaust type constant-pressure sounding balloon and an air inflation method of the directional exhaust type constant-pressure sounding balloon. The directional exhaust type constant-pressure sounding balloon comprises an air bag, a base, a pressure limiting mechanism and pressure relief components. The pressure limiting mechanism is installed on the air bag through the base; the pressure limiting mechanism comprises a pressure relief shell and a pressure relief piston, and the closed end of the pressure relief shell is communicated with the internal space of the air bag; the open end of the pressure relief shell is provided with an annular protrusion, and the pressure relief piston is connected with the annular protrusion through a tension spring; the wall face in the middle of a shaft of the pressure relief shell is provided with a plurality of through holes B, and a plurality of pressure exhaust holes are formed in a pressure exhaust cavity; a shifting lever is vertically arranged on the side face, backing on to the pressure relief shell, of the closed end of the pressure relief piston; a connection rack comprises a plurality of connection claws corresponding to the pressure relief components in number, the shifting lever is connected with the connecting claws in a rotating mode, and the connecting claws are fixed together through a fixing seat; an air exhaust nozzle is formed in the bottom of the pressure exhaust cavity and comprises an air exhaust piston rod, and the air exhaust piston rod is movably connected with the fixing seat through a universal shaft.

Description

technical field [0001] The invention relates to a directional exhaust type constant-pressure 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] Except for one meteorological station in Hong Kong (which imported the AUTOSONDE system from Finland's vaisala company), all the high-altitude meteorological detection side stations and the inflation of 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 unman...

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
