Description
Technical field
The present invention is specifically related to a kind of captive balloon automatic pressure control device.
Background technology
At present, captive balloon is a kind of unpowered lighter-than-air flight device, be generally soft structure, there is the air bag that is full of buoyance lift gas (being generally helium) and the balloonet that is full of air, the buoyancy that relies on air bag to produce in air overcomes the weight of himself and leaves a blank to realize, keep gasbag pressure in specialized range by the amount of air that regulates balloonet, to maintain good aerodynamic configuration.
The pressure regulating system of captive balloon is made up of Measurement &control computer, differential pressure pick-up and blower fan and valve conventionally.Measurement &control computer gathers gasbag pressure, carries out control law calculating, realizes the adjusting of gasbag pressure by the switching of controlling blower fan, valve.Gasbag pressure during higher than higher limit, is opened valve venting, and gasbag pressure is during lower than lower limit, the machine that blows in inflation.In actual use, once Measurement &control computer fault, pressure adjusting function will completely lose the method, have a strong impact on the safety of captive balloon.Certainly, can carry out redundancy design to Measurement &control computer, manage to improve its reliability, but cost be high, and cannot avoid Generic fault.
Summary of the invention
Object of the present invention is exactly for current above-mentioned deficiency, and a kind of captive balloon automatic pressure control device is provided.
The present invention is made up of A pressure switch, B pressure switch, A relay, C pressure switch, D pressure switch and B relay, blower fan composition circuit series on A pressure switch, B pressure switch, A relay and captive balloon, the A group contact of A relay is connected in parallel on the two ends of A pressure switch, the B group contact of A relay is connected on blower fan two ends, C pressure switch, D pressure switch, B relay and the valving on captive balloon become circuit series, the A group contact of B relay is connected in parallel on the two ends of C pressure switch, and the B group contact of B relay is connected at valve two ends.
Advantage of the present invention is: the captive balloon pressure automatic control method the present invention relates to, there is safe and reliable, simple structure, the feature such as with low cost, can be used as the emergent control device of the pressure controlled one of captive balloon, the safety that has effectively improved captive balloon.
Brief description of the drawings
Fig. 1 is A pressure switch, B pressure switch, A relay and blower fan annexation structural representation.
Fig. 2 is C pressure switch, D pressure switch, B relay and valve mechanism schematic diagram.
Detailed description of the invention
As Fig. 1, shown in 2, the present invention is by A pressure switch 1, B pressure switch 2, A relay 3, C pressure switch 5, D pressure switch 6 and B relay 7 form, A pressure switch 1, B pressure switch 2, blower fan 9 on A relay 3 and captive balloon forms circuit series, the A group contact of A relay 3 is connected in parallel on the two ends of A pressure switch 1, the B group contact of A relay 3 is connected on blower fan 9 two ends, C pressure switch 5, D pressure switch 6, valve 10 on B relay 7 and captive balloon forms circuit series, the A group contact of B relay 7 is connected in parallel on the two ends of C pressure switch 5, the B group contact of B relay 7 is connected at valve 10 two ends.
Mode of operation:
The operating pressure value of A pressure switch 1 is made as to 250Pa, the operating pressure value of B pressure switch 2 is made as 400Pa, the operating pressure value of C pressure switch 3 is made as 550Pa, the operating pressure value of D pressure switch 4 is made as 450Pa, so just can control gasbag pressure between 250Pa ~ 550Pa, whole workflow is as follows:
Once a), after Measurement &control computer fault, gasbag pressure is out of control, according to the residing state of fault, pressure may go up to the air also and likely to reduce, and to be reduced to example, and blower fan, valve are all in closed condition.
B), after gasbag pressure is lower than 250Pa, the normally closed contact of A pressure switch 1 and B pressure switch 2 is all in on-state, the line Bao get electricity of A relay 4, and corresponding contacts closure, blower fan is started working; When gasbag pressure is during higher than 250Pa and lower than 400Pa, the normally closed contact of A pressure switch 1 disconnects, and the normally closed contact of B pressure switch 2 is still connected, and because the A group contact that has A relay 4 interlocks (seeing Fig. 1), thereby blower fan 9 is held open state.
C), after gasbag pressure is higher than 400Pa, the normally closed contact of B pressure switch 2 disconnects, the line bag dead electricity of A relay 4, and corresponding contacts disconnects, and blower fan 9 cuts out.
D), due to the variation of environment and state of flight, after causing gasbag pressure higher than 550Pa, the open contact of C pressure switch 3 and D pressure switch 4 is in on-state, the line Bao get electricity of B relay 7, and corresponding contacts closure, valve is started working; When gasbag pressure is during lower than 550Pa and higher than 450Pa, the open contact of C pressure switch 3 disconnects, and D pressure switch 4 open contacts are still connected, and because the A group contact that has B relay 7 interlocks, thereby valve 10 is held open state.
E), after gasbag pressure is lower than 450Pa, the open contact of D pressure switch 4 disconnects, the line bag dead electricity of B relay 7, and corresponding contacts disconnects, and valve 10 is closed.
