The air duct is arranged, and an air bag is accommodated into the air duct to be detected; by controlling wind force and the wind direction in the air duct, the complex environment in the air where the floating air bag is located is simulated, the test requirements are met, and detection results are more accurate and reliable.
Description
Technical field
The present invention relates to floating air bag leak test platform, more particularly relate to be applied in the wind regime generating means in floating air bag leak test platform.
Background technology
Aerostatics is as a kind of aircraft that relies on buoyancy lift-off, there is the unique advantages such as cost is low, the fixed point hang time is long, load-carrying ability is large, noise is low, energy consumption is little, security good, efficiency-cost ratio is high, at many civil areas such as communications and transportation, environmental monitoring, remote sensing communication, sightseeing tour, emergency management and rescue, have purposes and good prospect widely.The buoyancy of aerostatics derives from the utricule that floats air bag the light gas such as helium is housed, and the leak of balloon surface will cause the abnormal stress of utricule to concentrate and Leakage Gas, and can greatly affect the serviceable life of aerostatics.Therefore, for air bag, in environment of living in, may there is the detection of the situation of leaking extremely important.
In prior art, for the leak detection of floating air bag, be that the form with single fan air-supply can not meet for the requirement of the simulation of complex environment of living in aloft of floating air bag on unlimited testing table.
Summary of the invention
The present invention is for avoiding the existing weak point of above-mentioned prior art, a kind of floating air bag leak test typhoon source generating means is provided, to meet for the requirement of the simulation of complex environment of living in aloft of floating air bag, improve the accuracy detecting for floating air bag on testing table.
The present invention is that technical solution problem adopts following technical scheme:
The design feature of the floating air bag leak test typhoon of the present invention source generating means is: be provided for holding the air channel of tested air bag, the two ends in described air channel are set to respectively air intake and outlet air end.
The design feature of the floating air bag leak test typhoon of the present invention source generating means is also:
The electric fan of respectively blowing that is arranged in array on the end face of described air intake, forms air-supply end face, and air force and the start-stop time of the described electric fan of respectively blowing can independently be controlled; A side at described air-supply end face in air channel and be in rectification wire side is set on transversal section, air channel.
In described air channel, the bottom that is in air channel is fixedly installed respectively wind speed wind direction sensor and flowmeter.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention arranges air channel, and air bag is incorporated in air channel and is detected, and controls, and then simulate floating air bag residing complex environment aloft by the wind-force in air channel and wind direction, meets testing requirements, makes testing result more accurately and reliably.
2, the air intake of the present invention in air channel each blowing fan that is arranged in array, forms air-supply end face, can simulate more accurately the floating residing physical environment of air bag.
3, the present invention arranges wind transducer and flowmeter in air channel, and according to detecting the data control of further blowing, is convenient to the automatic control to simulation process.
4, the present invention is simple in structure, occupation of land space is little, low cost of manufacture.
Fig. 1 is structural representation of the present invention.
