[0002] Acoustic releasers are mainly used in the field of marine engineering. With the rise of marine scientific research and other activities, they have become necessary equipment to ensure the deployment and recovery of various marine instruments and equipment. They are mainly composed of two parts: the surface deck unit and the underwater acoustic release and recovery device.

[0036] The release mechanism is connected to the multiplier mechanism, and the release link 23, the release hook 25 and the release ring 24 form an amplifying lever. The lever principle is used to reduce the load directly acting on the release mechanism and the releaser housing, thereby reducing the impact and shock on the releaser structure and internal parts when a large load is released.

[0037] Specifically, combined Figures 7 to 9As shown, the release mechanism includes: a rotating latch 22, a release link 23, a release ring 24, a release hook 25, a connecting shaft pin 26, a release end shaft pin 27 and a multiplier shaft pin 28. The release end shaft pin 27 is located on the release end structure 6, and one end of the release link 23 is coaxially constrained and connected to the release end structure 6 through the release end shaft pin 27. The middle of the release link 23 is connected to the release ring 24, and the other end of the release link 23 is interlocked with the rotating latch 22. The release ring 24 is hingedly connected to one end of the release hook 25 through the connecting shaft pin 26. The multiplier shaft pin 28 is located on the multiplier structure, and the other end of the release hook 25 is coaxially constrained and connected to the multiplier structure through the multiplier shaft pin 28.

[0038] The release link 23, release ring 24, release hook 25 and multiplier structure are adopted to amplify the lever arm of the release hook 25, which can effectively reduce the load transmitted to the motor by the total load, amplify the release load, and improve the release reliability of the motor.

[0039] Specifically, combined Figure 8 As shown, one end of the release link 23 connected to the release end shaft pin 27 is columnar, and the other end of the release link 23 connected to the rotating latch 22 is cubical. The upper surface and the front and rear surfaces of the cubical shape are penetrated by openings to form a lock hole structure. The lock hole structure is complementary to the structure of the rotating latch 22. The rotating latch 22 restrains the release mechanism through the friction force of the complementary structures, and the locking and releasing actions of the release mechanism are completed by rotating the rotating latch 22.

[0040] The release mechanism is driven by a structural interlocking form of a rotating latch 22 and a release link 23. The overall structure is simple and reliable, and the release mechanism opens quickly and efficiently.

[0041] Specifically, combined Figure 2 As shown, the multiplier structure includes: an upper end connection member 12, a lower end connection member 13, a multiplier structure member 14, a hanging ring 15 and a concave end 16. The multiplier structure member 14 is located on one side of the releaser housing. One side of the upper end connection member 12 is connected to the hanging structure member 1 through an upper end shaft pin 11, and the other side of the upper end connection member 12 is connected to the upper side of the multiplier structure member 14 through a fifth bolt 21. One side of the lower end connection member 13 is fixedly connected to the release end structure member 6 through a fourth bolt 20, and the other side of the lower end connection member 13 is fixedly connected to the multiplier structure member 14 through a fifth bolt 21. The hanging ring 15 is located at the upper end of the multiplier structure member 14, and the hanging ring 15 is above the upper end connection member 12. The bottom of the multiplier structure member 14 is provided with a concave end 16.

[0042] A multiplier structure is adopted which is connected in parallel with the releaser housing, and both ends of the multiplier structure are fixedly connected with the upper and lower ends of the releaser housing, thereby increasing the structural stability under large load release.

[0043] Specifically, combined Figure 7 and Fig.10 As shown, the release hook 25 and the concave end 16 at the bottom of the multiplier structure 14 form a release lock hole 43, and the release lock hole 43 is used to hang the weight 45. Under the hanging action of the weight 45, the release ring 24 is in a vertical state parallel to the length direction of the releaser shell, and the release hook 25 is in a horizontal state. The weight 45 is hung in the release lock hole 43 formed by the release hook 25 and the concave end 16 at the bottom of the multiplier structure 14 through the hanging ring 44, and the lifting ring 15 is connected to the marine equipment 49 and the buoyancy ball 50 through a cable.

[0044] Specifically, combined Figure 3 As shown, the releaser housing includes: an upper sealing cover 3, a cylindrical sealing cabin 4, a lower sealing cover 5 and a connecting rod 7. The upper sealing cover 3 is fixedly installed on the upper side of the cylindrical sealing cabin 4 by a first bolt 17, and the lower sealing cover 5 is fixedly installed on the lower side of the cylindrical sealing cabin 4 by a second bolt 18. The upper sealing cover 3 and the lower sealing cover 5 are both provided with deep grooves on the axial surfaces and radial surfaces in contact with the cylindrical sealing cabin 4, and the releaser housing O-ring 8 is provided in the deep groove. The release end structure 6 is fixedly installed on the lower side of the lower sealing cover 5 by the second bolt 18. The lower sealing cover 5, the upper sealing cover 3 and the hanging structure 1 are connected by a connecting rod 7, and the transducer 10 is fixedly connected to the upper sealing cover 3 by a third bolt 19.

[0045] The connecting rod 7 is used to connect the hanging structure 1, the upper sealing cover 3 and the lower sealing cover 5, so the connection strength of the releaser housing is improved, and the overall structure is firm and reliable under the action of large loads.

[0046] Specifically, combined Figure 4 As shown, the battery assembly includes: batteries 33, battery fixing plates 34 and battery support columns 35. The batteries 33 are fixed on the battery fixing plates 34. The battery fixing plates 34 have 4 layers in total. Each layer is connected by 6 battery support columns 35 evenly distributed in an annular direction. Seven batteries 33 are fixed on each layer of the battery fixing plates 34. The battery assembly has a total of 28 batteries 33. The battery assembly is fixedly mounted on the lower end sealing cover 5 through 5 cabin support columns 32.

[0047] Specifically, combined Figure 5 and Figure 6 As shown, six connecting columns 2 are evenly distributed in the circumferential direction, both ends of the connecting columns 2 are screw heads, the upper ends of the connecting columns 2 are connected to the threaded holes on the hanging structure 1, the lower ends of the connecting columns 2 are connected to the threaded holes on the upper sealing cover 3, the transducer 10 is connected to the upper side of the upper sealing cover 3, the transducer 10 is located between the hanging structure 1 and the upper sealing cover 3, the transducer 10 is surrounded by six connecting columns 2 evenly distributed in the circumferential direction, and two coaxial deep grooves with different radii are arranged on the lower surface of the transducer 10, and a transducer O-ring 9 is arranged in the deep groove.

[0048] Specifically, combined Figure 7 As shown, the motor assembly includes: a reduction motor 36, a motor fixing part 37, a motor support column 38, a coupling 39 and an extension shaft 40. The reduction motor 36 is fixed on the motor fixing part 37. The motor fixing part 37 is fixedly connected to the lower end sealing cover 5 through the motor support column 38. One end of the coupling 39 is connected to the shaft end of the reduction motor 36, and the other end of the coupling 39 receives the extension shaft 40. The bottom of the extension shaft 40 is fixedly connected to the rotating pin 22. The extension shaft 40 passes through the lower end sealing cover 5 and the release end structure 6. Two deep grooves are distributed on the surface of the extension shaft 40. The extension shaft O-ring 41 is fastened in the two deep grooves. The coupling 39 and the lower end sealing cover 5 are filled with a coupling O-ring 42.

[0049] The working principle of the present invention is:

[0050] like Fig.10 As shown, the heavy object is connected to the mounting ring 44 through the first cable 46, and the mounting ring 44 is mounted on the release lock hole 43 formed by the release hook 25 and the bottom end of the multiplier structure 14. The releaser as a whole is connected to one end of the marine equipment 49 through the second cable 47 at the lifting ring 15, and the other end of the marine equipment 49 is connected to the buoyancy ball 50 through the third cable 48.

[0051] Under the action of the heavy object 45, the releaser as a whole and the connected marine equipment 49 and buoyancy ball 50 sink to the bottom of the water. When the operating vessel runs to the area above the entire system to be recovered, it sends an acoustic signal recovery instruction to the underwater acoustic releaser.

[0052] When the transducer 10 receives the acoustic signal instruction, it converts the acoustic signal into an electrical signal and transmits it to the control board 31. The control board 31 drives the reduction motor 36 to rotate, and the motor drives the coupling 39 and the connected extension shaft 40 to rotate, thereby driving the rotation pin 22 to rotate. When the rotation pin 22 rotates 90°, the structure between the rotation pin 22 and the release link 23 is interlocked, and the release mechanism loses the friction constraint between the rotation pin 22 and the release link 23. The release end shaft pin 27 of the release link 23 rotates clockwise around the release end shaft pin 27 and passes through the annular gap in the middle of the release ring 24. At this time, the release ring 24 loses the connection constraint with the release link 23 end. The release ring 24 and its hinged release hook 25 rotate counterclockwise around the multiplier shaft 28 under the force of the weight 45 mounted. The release lock hole 43 formed by the release hook 25 and the bottom of the multiplier structure 14 opens along with the rotation of the release hook 25, and the mounting ring 44 and the weight 45 are separated to complete the release action.

[0053] When the mounting ring 44 and the weight 45 are separated and the release action is completed, the acoustic releaser, under the action of the connected buoyancy ball 50, the entire system begins to float rapidly, and finally the releaser and the marine equipment 49 and the buoyancy ball connected by the cable float to the surface. The personnel on the working vessel on the water use a winch and a cable to recover the entire system to shore.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
