Description

Marine autonomous rescue device based on hot air balloon

Technical Field

The disclosure relates to a fire balloon and a marine autonomous rescue device based on the fire balloon.

Background

The problem of safe escape from sea has been paid much attention to, and life saving equipment equipped on ships mainly includes rescue boats, life rafts, life floats and the like. The life-saving equipment helps trapped people to escape from the water surface, but when serious oil and fire disasters occur on the water surface or toxic gas exists on the water surface, the life safety of people can be greatly threatened by the escape mode through the water surface route. And at present, the rescue force is stronger, and people in danger only need to successfully escape from the dangerous area in danger of the ship and persist in survival in the gold rescue time, so that the rescue probability is still very high. Therefore, it is important to invent a lifesaving device which can help people safely escape from the dangerous area in danger.

In the above fire balloon, the control device comprises a rotating disc, the rotating disc is rotatably arranged at the upper edge of the basket frame of the fire balloon through a steering shaft, the middle part of the rope is fixed on the tie buckles of the frame of the wind wings, two ends of the rope are respectively wound in the annular grooves at the upper end and the lower end of the steering shaft through rope guiding devices, wherein the two ends of the rope are wound on the steering shaft in the same direction.

In the hot air balloon, the reinforcing strip is arranged at the position of the equator of the balloon.

In the above fire balloon, the bracket of the fire balloon burner is detachably mounted on the basket frame.

In the fire balloon, a life raft is arranged in the hanging basket frame.

Detailed Description

As shown in fig. 1 and 2, the autonomous rescue apparatus at sea comprises a fire balloon and a life raft 3 which can be arranged in a gondola frame 1 of the fire balloon. The liferaft 3 may be a regular octagonal inflatable liferaft. The basket frame 1 may be a regular octagonal basket and may be woven from rattans. The burner 10 of the hot air balloon is arranged on the tray 8, and the bracket of the tray 8 can be detachably fixed on the hanging basket frame 1 through a fastener such as a bolt.

The hot air balloon comprises wind wings, a control device and a reinforcing strip 16. The reinforcing tape 16 is fixed to the balloon 11 of the hot air balloon and is made of a cloth material thicker than the balloon 11. The reinforcing strip 16 may be disposed at an equatorial location of the balloon 11. The sailcloths 14 of the wind wing are arranged in a rigid frame 12, the frame 12 being substantially H-shaped. The frame 12 is mounted on a reinforcing strip 16 by means of a revolute joint 17, which is able to revolve in a horizontal plane around the revolute joint 17. The control device is connected with the wind wing through a rope 9 to control the wind wing to rotate in the horizontal plane. In a possible embodiment, two of said wings are centered symmetrically with respect to the center of the annular reinforcing strip 16, one of said control devices being associated with each of said wings.

The control device comprises a rotating disc 6 which is rotatably arranged on the upper edge of the basket frame 1 through a steering shaft. The steering shaft has annular grooves in its upper and lower ends around which the rope 9 is wound. The middle part of the rope 9 is fixed to a tie 13 of the wing frame 12, and both ends of the rope 9 are respectively wound in annular grooves at the upper and lower ends of the steering shaft via rope guide means. Wherein both ends of the rope 9 should be wound in the same direction around said steering shaft. Furthermore, the rope 9 is provided with a scale, and the angle of the wind wing is reflected by the scale.

The rope guide comprises an upper mounting ring 15 mounted on a reinforcing strip 16 on both sides of the wind wing, a lower mounting ring 4 mounted on the upper end of the basket frame 1 on both sides of the steering shaft, and a pulley 2 located below the lower mounting ring 4. As shown in fig. 2 and 3, one end of the rope 9 passes through the upper mounting ring 15 on the right side of the wind wing, the pulley 2 on the right side, and the lower mounting ring 4 on the right side of the steering shaft, and then is wound in the annular groove at the upper end of the steering shaft. The other end of the rope 9 passes through an upper mounting ring 15 on the left side of the wind wing, a pulley 2 on the left side and a lower mounting ring 4 on the left side of the steering shaft and then is wound in an annular groove at the lower end of the steering shaft.

The control device comprises a locking device 5 which is of a telescopic construction. The locking device 5 is arranged on the upper edge of the hanging basket frame 1 in a sliding mode and is close to the steering shaft of the rotating disc 6. When the locking device 5 is in a contraction position, the locking device can move to the position right below the rotating disc 6; the locking device 5, in the extended state, may extend through an opening in the rotatable disc 6, preventing rotation of the rotatable disc 6.

When a ship has a major safety accident on the sea and needs to be abandoned for escape, the wind wings and the ropes 9 are installed on the hot air balloon, hot air is filled into the hot air balloon by using a ship blower, the life raft 3 is arranged in the hanging basket frame 1, and after the hot air balloon 11 is inflated and molded, the balloon 11 is heated by using the combustor 10 to lift the hot air balloon. The angle of the wind wings and thus the advancing direction of the hot air balloon can be controlled to some extent in the air by the rotating disc 6. After the hot air balloon leaves the dangerous water area and reaches the safe water area, the control valve 7 of the burner 10 can be closed or cut off, so that the hot air balloon gradually falls to the water surface. The connection of the bracket of the tray 8 of the burner 10 to the basket frame 1 is then released and the liferaft 3 will detach from the basket frame 1 under the influence of buoyancy. The rope 9 on the hot air balloon may be connected to the liferaft 3, which may increase the probability of the trapped person being discovered due to the large volume of the balloon 11 of the hot air balloon. The marine autonomous rescue device based on the hot air balloon can help people in danger escape from the air and can guarantee that the people in danger live for a long time at sea.
