Referring to fig. 13 to 18, the release cover 20 is an integrated release cover 20, which is not separated from the profile buoy immediately after entering water, and provides an additional underwater deceleration effect for the profile buoy, so that the submerged distance of the profile buoy is shallower, and the air drop distribution can be performed in shallower water areas, compared to the split release cover 20.

The cup cover 2001 is of a cup-shaped structure, a plunger hole 2009 is arranged on the outer side of the bottom of the cup cover 2001, and the plunger hole 2009 is a blind hole. The plunger 2002 has an axial dimension that is less than an axial dimension of the plunger bore 2009 such that the plunger 2002 is movable within the plunger bore 2009.

The plunger 2002 comprises a plunger body, a hook 2008, a spring 2007 and a ball 2006, wherein a cavity is arranged in the plunger body, the cavity is arranged along the radial direction of the plunger body, one end of the cavity is open, and the opening is located on the side wall of the plunger 2002. A first groove 2014 is disposed on the sidewall of the plunger hole 2009 and corresponding to the opening, and the first groove 2014 is a spherical structure. A ball 2006 is disposed within the cavity with one side extending out of the opening and engaging the first slot 2014. A spring 2007 is disposed in the cavity, one end of the spring is abutted against the other side of the ball 2006, one side of the ball 2006 is pressed in the first groove 2014, and a stroke distance is formed between the inner end of the plunger 2002 and the bottom of the plunger hole 2009. The hook 2008 is fixed to the plunger body, and its hook portion extends out of the cup 2001. A notch for moving the hook 2008 is formed on the sidewall of the cup cover 2001 along the axial direction.

Under normal conditions, the ball-shaped member 2006 is pressed in the first groove 2014 under the action of the spring 2007, and at this time, a stroke distance is formed between the inner end of the plunger 2002 and the bottom of the plunger hole 2009; when an external force acts on the plunger 2002, the spherical component 2006 moves into the cavity to be separated from the first groove 2014, and the plunger 2002 moves towards the bottom of the plunger hole 2009; as plunger 2002 moves toward the bottom of plunger hole 2009, hook 2008 moves along with it.

An annular groove 2015 is formed in the circumferential direction of the cup cover 2001, the belt 2005 is made of an elastic material, two notches are formed in the length direction of the belt 2005 at intervals, and the two notches can be formed at two ends of the belt 2005. The strap 2005 wraps within the channel 2015, and the two notches overlap and hook onto the hooks 2008 of the plunger 2002. When the hook 2008 moves with the plunger 2002 toward the bottom of the plunger hole 2009, the notch of the strap 2005 disengages from the hook 2008, and the strap 2005 can spring open under the action of the elastic force, releasing the binding band 19.

Be equipped with second recess 2011 in the bottom outside of cup 2001, the outer end surface of plunger 2002 is equipped with the third recess 2012 of cooperating with second recess 2011, and a horizontal pole is installed in second recess 2011 and third recess 2012, and unexpected trigger plunger 2002 when preventing artificial operation, and the normal trigger under the sea water impact when not influencing into water.

One end of the binding belt 19 is fixedly provided with a pin 2003, the outer side wall of the cup cover 2001 is provided with a fourth groove which is recessed inwards, a slope is arranged on the fourth groove and on one side far away from the bottom of the cup cover 2001, and one end of the binding belt 19 is matched in the fourth groove through the pin 2003 and can slide out of the slope of the fourth groove; the other end of the binding band 19 is tied to the opening of the side wall of the loading tub 18 through a groove 2015, and the outer side thereof is pressed into the groove 2015 by the belt 2005.

At least one drain hole 2010 is provided in the bottom of the cup 2001 through which water can freely flow to facilitate separation of the release cap 20 from the bottom of the profile buoy. The release cover 20 further comprises a second torsion spring 2004, a fifth groove 2013 is formed in the inner side of the bottom of the release cover 20, the second torsion spring 2004 is rotatably mounted in the fifth groove 2013, two ends of the second torsion spring are respectively inserted into through holes formed in the cup cover, and the rebounding end of the second torsion spring abuts against the bottom end of the section buoy.

When the release cover 20 and the section buoy enter water, the binding band 19 is released from the release cover 20 and then is unbound; because the release cover 20 is located at the bottom end of the section buoy, the release cover 20 still sinks a certain distance along with the section buoy, in the process, water continuously flows into the release cover 20 from the water leakage holes 2010, when the sum of the gravity of the release cover 20 and the elastic force of the second torsion spring 2004 is larger than the resistance of the water, the release cover 20 bounces away from the bottom end of the section buoy under the action of the second torsion spring 2004 to realize separation from the section buoy, and when the release cover 20 is separated from the section buoy, the release cover 20 does not pass through the section buoy, and the surface of the section buoy cannot be scratched.

The air-drop method comprises the following steps:

s1, loading two ends of a section buoy into corresponding loading barrels 18 and release covers 20 respectively, arranging a binding belt 2005 around the circumference of the release covers 20 and hooking the binding belt on hooks 2008 of a plunger 2002, connecting one end of a binding belt 19 with the loading barrels 18, matching the other end of the binding belt 19 on the release covers 20 and pressing the binding belt 2005, and clamping the section buoy between the loading barrels 18 and the release covers 20; and then put into the gravity tube 15 together.

S2, after the carrier is loaded in a designated sea area by an airplane, the loading barrel 18 and the release cover 20 clamp the section buoy and slide down from the gravity tube 15.

S3, air enters the loading barrel 18 through the air inlet hole, the barrel cover 1801 is pushed open, and the parachute 16 is ejected from the loading barrel 18 and decelerated.

S4, after the section buoy, the loading barrel 18 and the release cover 20 enter water, the plunger 2002 moves towards the bottom of the plunger hole 2009 under the impact of seawater, the strap 2005 is separated from the hook 2008, the binding belt 19 is released, and the loading barrel 18 is separated from the top of the section buoy.

S5, seawater enters the release cover 20, and when the sum of the elasticity of the second torsion spring 2004 and the gravity of the release cover 20 exceeds the resistance of the seawater, the release cover 20 bounces off the section buoy under the action of the second torsion spring 2004, and the aerial delivery and the distribution of the section buoy are completed.

By adopting the air-drop device, in the preparation air-drop distribution stage, the stabilizing disc 4 is fixed on the top end cover 3 of the section buoy through the flange plate 401 by screws, all the blades 405 are pressed by the lower edge of the loading barrel 18 and attached to the pressure-resistant shell 5, and the spring plunger 404 and the first torsion spring 403 are stressed and compressed. The parachute 16 and the parachute cord 17 are arranged in a parachute cabin 1802 of the loading barrel 18, and a barrel cover 1801 of the loading barrel 18 is pressed at an opening at the upper end of the parachute cabin, so that the parachute 16 is prevented from being accidentally ejected.

At this time, the integrated release cover 20 is in an unfired state, and the ball-type member 2006 and the spring 2007 press the plunger 2002 into the plunger hole 2009 of the release cover 20, so that the plunger 2002 does not move up and down in the plunger hole 2009. The release housing 20 fits over the bottom end cap 6 of the profile buoy and the second torsion spring 2004 within the release housing 20 is compressed within the fifth recess 2013 in the bottom interior of the release housing 20. The strap 2005 wraps within the channel 2015 and hooks over the hooks 2008 of the plunger 2002 through the notch. One end of the binding band 19 is pressed by the binding band 2005, and the other end is fixed on the loading barrel 18; because the second torsion spring 2004 has a certain elastic potential energy after being compressed, the binding band 19 can tighten the loading bucket 18 and the release cover 20 at the two ends of the sectional buoy, thereby ensuring that the sectional buoy and the air-drop device cannot be separated in the air-drop process.

The profile buoy and the air-drop device can be arranged by being arranged in a launcher or a gravity tube 15 of the airplane. When the aerial delivery is deployed, the profile buoy slides off the aircraft through the gravity tube 15 after the aircraft has flown to the designated sea area. After air enters the interior of loading barrel 18 through air inlet holes in the side surface of loading barrel 18, barrel cover 1801 is separated from loading barrel 18, parachute 16 is popped out, and the whole structure is decelerated.

During the entry of the profile buoy into the water, the integral release cover 20 at the bottom end thereof first contacts the seawater. Due to the impact of seawater, the plunger 2002 gets rid of the pressing force of the ball-shaped member 2006 and the spring 2007, and moves together with the hook 2008 along the plunger hole 2009 of the release cover 20, the hook 2008 moves out of the recesses at the two ends of the strap 2005, and the strap 2005 is made of an elastic material, so that the strap 19, which is originally pressed by the strap 2005 in the groove 2015 of the cup 2001, is popped out and separated from the cup 2001, so that the integral release cover 20 is separated from the section buoy but sinks for a certain distance together with the section buoy, and when the sum of the elastic force of the second torsion spring 2004 and the gravity of the integral release cover 20 exceeds the resistance of water, the integral release cover 20 will pop out of the section buoy under the action of the second torsion spring 2004. Because the integrated release cover 20 is pushed downward away from the profile buoy and does not pass through the profile buoy, the risk of scratching the shell is avoided; and this application air-drop device still can follow the certain distance of section buoy after going into water, consequently the speed reduction effect is better, and section buoy's dive distance is shallower. After the aerial delivery is completed, the parts of the aerial delivery device other than the integrated release cover 20 are separated from the profile buoy from the upper end.

After the air-drop device is separated from the section buoy, the blade 405 of the stabilizing disc 4 is bounced off by the first torsion spring 403, the spring plunger 404 is bounced out and inserted into the limiting hole of the blade 405, and the blade 405 is not rotated around the middle shaft 402 any more and is completely fixed. Due to the concave and downward orientation of the blade 405, the profile buoy can achieve fast ascent and more stable communication at the water surface during detection.

After the section buoy enters water, normal detection work is started, and the communication module 9 and the antenna 1 receive and transmit instructions and data. When the section buoy needs to dive, the motor 10 rotates forwards, and the output shaft of the motor 10 drives the screw 1401 to rotate; because the screw nut 1405 which is installed on the screw 1401 in a threaded manner is arranged in a rotation stopping manner and is fixed with the piston push rod 1411, the screw nut 1405 can only move along the axial direction of the screw 1401, so that the piston push rod 1411 is driven to move along the axial direction of the screw 1401; because the piston push rod 1411 is designed with a dynamic sealing structure, when the piston push rod moves towards the cabin, pressure difference exists between the inside of the water inlet cavity and the outside, and outside water enters the water inlet cavity through the filter disc arranged in the plug 7. At the moment, the drainage volume of the section buoy is reduced, the buoyancy borne by the section buoy in water is reduced, and the section buoy performs diving movement under the condition that the gravity is larger than the buoyancy.

Similarly, when the section buoy needs to float upwards, the motor 10 and the lead screw 1401 rotate reversely, the lead screw nut 1405 drives the piston push rod 1411 to move outwards, and water in the water inlet cavity is discharged outside the section buoy again through the filter disc. The volume of the device is increased, the buoyancy borne by the device in water is increased, and the device can float upwards under the condition that the buoyancy is larger than the gravity.
