Description

Technical Field

[0001] The invention relates to the technical field of floating escape equipment, in particular to a floating escape obstruction deceleration system. Background Art

[0002] After a submarine crashes and sinks, the crew often needs to leave the submarine and surface to escape danger. First, they inflate the escape suits they wear, and then surface at a constant speed of about 3m / s per second. When surfacing to a depth of less than 30m, in order to reduce the occurrence of hypotensive disease, the lower limbs of the escape suit are inflated to expand laterally to reduce the surfacing speed at shallow depths, which is equivalent to staying at a shallow depth for a longer time, which is conducive to the desaturation of dissolved gases in the body. If the surfacing speed can be reduced to 1m / s, the chance of safe escape will be greatly increased. Traditional escape methods can only meet the safety of less than 200m underwater at most. If the depth is greater, there is a risk of decompression sickness. Summary of the invention

[0015] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0016] like Figure 1 and Figure 2As shown, this embodiment provides a floating escape obstruction deceleration system, which can be set on the lower limbs of the escape suit worn by the crew. The system specifically includes an obstruction deceleration sleeve, which is set on the lower limbs of the escape suit through the obstruction deceleration sleeve. The obstruction deceleration sleeve includes a first box body 1 and a second box body 2 located at both ends, one side of the first box body 1 and one side of the second box body 2 are connected by a first elastic band 3, and the other side of the first box body 1 and the other side of the second box body 2 are connected by a second elastic band 4. The first box body 1, the first elastic band 3, the second box body 2 and the second elastic band 4 form a circular cavity for the lower limbs of the escape suit. Due to the elastic effect of the first elastic band 3 and the second elastic band 4, the obstruction deceleration sleeve is set and fixed on the lower limbs of the escape suit. The first box body 1 and the second box body 2 both include an outermost side panel 5, i.e., a side panel away from the elastic band. A waterproof shell 6 is fixed on the inner wall of each of the outermost side panels 5. A motor 7 is fixed in each of the waterproof shells 6. A through hole is opened on each of the waterproof shells 6. A rubber sealing ring is fixed in each of the through holes. A rubber sealing ring is passed through the output shaft of each of the motors 7 and a first gear 8 is sleeved and fixed on the end. Each of the first gears 8 is meshed with the second gear 9. A rotating shaft 10 is passed through and fixed on each of the second gears 9. A first bearing 11 and a second bearing 12 are respectively fixed on both sides of the inner wall of each of the outermost side panels 5. A rotating shaft 10 is rotatably fixed between the first bearing 11 and the second bearing 12. Each of the rotating shafts 10 is fixed to the obstructed deceleration blade 13. A cavity 14 corresponding to the obstructed deceleration blade 13 is opened on each of the outermost side panels 5. The cavity 14 reserves space for the obstructed deceleration blade 13 to rotate outward.

[0017] A control button 15 and a water depth sensor 16 are provided on the outer surface of the outermost side plate 5 of the first box body 1, and a controller and a battery are fixed in the waterproof shell 6 of the first box body 1. The control button 15, the water depth sensor 16, and the motors 7 in the first box body 1 and the second box body 2 are all electrically connected to the controller, and the battery is electrically connected to the controller for power supply.

[0018] In specific use, when the crew needs to leave the boat and float to escape danger, the escape suit worn by the crew is first inflated, and then the system can be put on the left lower limb part and the right lower limb part of the escape suit. The crew presses the control button 15 corresponding to the left lower limb part and the right lower limb part, and the control button 15 sends a control signal. The controller receives the corresponding control instruction and controls the water depth sensor 16 to work. The water depth sensor 16 detects the current water depth position of the crew. Based on the current water depth position of the crew, the controller controls the motor 7 in the first box body 1 and the second box body 2 to rotate simultaneously, and at the same time drives the corresponding obstructed deceleration blade 13 to rotate outward to the target angle. At this time, the obstructed deceleration blade 13 is penetrated by the corresponding cavity 14 to increase the resistance encountered during the process of floating and escaping danger.

[0019] For example: when the water depth sensor 16 detects that the current water depth of the crew is the first water depth, the controller controls the motor 7 in the first box body 1 and the second box body 2 to rotate simultaneously based on the first water depth of the current water depth of the crew, and drives the corresponding obstructed deceleration blade 13 to rotate outward and rotate to the first target angle; when the water depth sensor 16 detects that the current water depth of the crew is the second water depth, the controller controls the motor 7 in the first box body 1 and the second box body 2 to rotate simultaneously based on the second water depth of the current water depth of the crew, and drives the corresponding obstructed deceleration blade 13 to rotate outward and rotate to the second target angle; when the water depth sensor 16 detects that the current water depth of the crew is the third water depth, the controller controls the motor 7 in the first box body 1 and the second box body 2 to rotate simultaneously based on the third water depth of the current water depth of the crew, and drives the corresponding obstructed deceleration blade 13 to rotate outward and rotate to the third target angle. As for the first water depth, the first target angle, the second water depth, the second target angle, the third water depth, the third target angle, etc., the technicians can set specific values ​​according to the actual needs of the floating escape process.

[0020] In the initial state, the obstructed deceleration blade 13 is vertical, and the water resistance encountered by the obstructed deceleration blade 13 is almost 0. As the obstructed deceleration blade 13 gradually rotates outward, the water resistance encountered by the obstructed deceleration blade 13 becomes greater. When the obstructed deceleration blade 13 is horizontal, the water resistance encountered by the obstructed deceleration blade 13 is the largest.

[0021] In the present invention, when the obstructed deceleration blade 13 gradually rotates outward and unfolds, the water resistance encountered by the obstructed deceleration blade 13 becomes greater, which may cause the obstructed deceleration sleeve to be unable to be firmly fixed on the lower limb part of the escape suit, and there is a possibility of sliding downward. Even if the obstructed deceleration sleeve slides downward, due to the blocking effect of the feet of the crew member's escape suit, the obstructed deceleration sleeve can only slide to the crew member's ankle at most and will not fall off the crew member.

[0022] During the floating escape process of the present invention, the higher the floatation, the greater the water resistance encountered, and the slower the floating speed, which is beneficial to desaturation of gases dissolved in the body and reduces the occurrence of hypotensive disease. The escape method of the present invention can meet the safety requirements within 300 meters underwater at most, which is superior to the existing floating escape method.

[0023] Although the specific embodiments of the present invention are described above, those skilled in the art should understand that these are only examples, and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
