Passenger balloons with redundant safety devices continue to decrease in atmospheric pressure as altitude increases after disengagement of the traction of the operating rope 9 and safety rope 8. As the passenger balloon is raised, the ambient pressure outside the balloon wall continues to drop. In order to maintain the pressure balance between the inside and outside of the balloon body 1, the balloon body 1 must be continuously inflated, and the tensile stress applied to the elastic material of the wall surface of the balloon body 1 is continuously increased. When the balloon flies off the ground too high, the expansion of the balloon body 1 causes the tensile stress on the elastic material on the wall surface of the balloon body 1 to exceed the yield tensile stress limit, and the balloon body 1 can explode instantly to cause personnel or property loss.

1) The tension sensor 10 prevents the balloon body 1 from flying off:

normally, the tension sensor 10 detects that the tension F is less than F0, 10N is less than or equal to F0 is less than or equal to 20N, and F0 is not equal to 15N, which indicates that the safety rope 8 or the operation rope 9 is out of restraint. The control module 13 waits for the time T1, T1 is equal to or less than 20s and equal to or less than 30s, and T1 is not set to be 25 s. The control module 13 again detects that the tension sensor 10 detects the tension force F. If F is less than F0, taking 10N less than or equal to F0 less than or equal to 20N, and not setting F0 equal to 15N, the balloon is broken or slipped after the safety rope 8 and the operating rope 9 are broken. The control module 13 will send a bleed signal to the emergency bleed module 101.

The emergency bleed module 101 commands the mover of the linear motor 19 to move upward. The pushing sleeve 17 will overcome the pulling force of the ball valve tension spring 20 to push the sealing ball 15 away from the air release opening of the balloon body 1. The pressure inside the balloon body 1 is reduced, the buoyancy is continuously reduced, and the balloon finally falls to the ground.

2) The speed sensor 6 prevents the balloon body 1 from flying off:

the speed sensor 6 detects the direction and the magnitude of the lifting speed V of the basket 11 in real time. When the ascending speed or descending speed of the balloon is not at a reasonable threshold value, the control module 13 sends a deflation signal to the emergency deflation module 101. Ensuring that the ascending speed or the descending speed is within a reasonable threshold value, and ensuring that the balloon flies safely.

The balloon-ascending speed threshold is set as Vu, 3m/s is less than or equal to Vu less than or equal to 7m/s, and the Vu is not set as 5 m/s. When V > Vu, which indicates that the ascending speed of the balloon is too fast, the control module 13 immediately sends a deflation signal to the emergency deflation module 101.

The emergency bleed module 101 commands the mover of the linear motor 19 to move upward. The pushing sleeve 17 will overcome the pulling force of the ball valve tension spring 20 to push the sealing ball 15 away from the air release opening of the balloon body 1. The pressure inside the balloon body 1 is reduced, the buoyancy is also reduced, and the ascending speed of the balloon is gradually reduced.

3) The inflation detection module 102 prevents the balloon body 1 from flying off and exploding:

when the balloon body 1 is filled with air, the guy cable 2 is tensioned, the lasso tension spring 23 is stretched, the sliding contact 25 is pulled to be in contact with the sliding resistor 26, and the expansion detection valve power supply 27, the electric wire, the sliding contact 25 and the sliding resistor 26 form a conductive circuit loop. The circuit loop sends a voltage signal U to the control module 13. When the balloon body 1 continuously expands, the sliding contact 25 continuously slides to the right, and the voltage signal U sent by the circuit loop to the control module 13 also continuously increases. When the tensile stress on the elastic material on the wall surface of the balloon reaches a certain value due to the expansion of the balloon, the inflation pressure of the balloon is over high, or the balloon flies into the high altitude and has the possibility of explosion. At this time, when the sliding contact 25 reaches the rightmost end, the voltage signal U sent by the circuit loop to the control module 13 is equal to U0, and no U0 is set to be 4V or more and no more than 6V, where U0 is 5V, the control module 13 will send the air release signal to the emergency air release module 101.

The emergency bleed module 101 commands the mover of the linear motor 19 to move upward. The pushing sleeve 17 will overcome the pulling force of the ball valve tension spring 20 to push the sealing ball 15 away from the air release opening of the balloon body 1. As the deflation process progresses, the pressure inside the balloon body 1 decreases.

After the deflation of the balloon is triggered by the above 3 conditions, the speed sensor 6 detects the speed of the balloon, and when the balloon goes from ascending to descending, the control module 13 sends a deflation stopping signal to the emergency deflation module 101. The emergency deflation module 101 commands the mover of the linear motor 19 to move downwards, the ball valve tension spring 20 pulls the sealing ball 15 back to the deflation port, and the deflation port stops deflating. The waiting time T0 is equal to or less than 30s and equal to or less than T0 and equal to or less than 60s, and T0 is not equal to or more than 40 s. The control module 13 detects the speed at which the balloon body 1 descends. And setting the descending speed threshold of the balloon body 1 as Vd, wherein Vd is more than or equal to 2.5m/s and less than or equal to 3.5m/s, and Vd is not equal to 3 m/s. When 0< | V < Vd, it indicates that the balloon descends slowly; when V | is not less than Vd, the descending speed is too fast, in order to prevent the balloon from landing hard, the control module 13 sends a fusing signal to the fuse 28, the two ends of the binding belt 29 are separated after the fuse 28 is fused, the parachute 30 is opened under the blowing action of the side wind, the descending speed of the balloon is reduced, and the balloon can safely descend at a stable speed.

Under emergency, can be by the emergent 1 flight of the emergent ventilative prevention balloon spheroid of manual cable and take off:

the passenger pulls the emergency pull ring 7 in the emergency pull cable box 5, the emergency pull cable 18 is pulled out along the cable sleeve 4, the part of the emergency pull cable 18 inside the pushing sleeve 17 can push upwards, the pushing force under the constraint action of the emergency pull ring 7 can overcome the pulling force of the ball valve tensioning spring 20, and the push rod 16 is pushed upwards. The sealing ball 15 is pushed away from the air leakage port of the balloon body 1, so that air leakage can be realized. When the passenger finds that the descending speed of the balloon is too fast, the pulling force acting on the emergency pulling ring 7 is reduced or the emergency pulling ring 7 is completely released. The ball valve tensioning spring 20 pulls the sealing ball 15 towards the bleed port which will either reduce the bleed or stop the bleed altogether.

The utility model discloses an electronic control emergency device loses heart, prevents that the passenger is not familiar with equipment and produces the potential safety hazard. The utility model discloses also adopt mechanical type emergency device, application manual control prevents to return ground because of the insensitive of electronic equipment, circumstances such as inefficacy or because of special circumstances urgently need, ensures the safety and stability of last one safeguard measure.
