Description

Technical Field

[0001] This application relates to the field of deep-sea exploration and marine engineering equipment technology, and in particular to a buoyancy storage rope device and an acoustic release system for an acoustic release device. Background Technology

[0002] In the deployment of deep-sea mooring systems and the recovery of deep-sea operational equipment, a specialized recovery system is typically required. This system generally consists of an acoustic release device, a buoyancy cable storage device, and a seabed load. The buoyancy cable storage device usually includes a buoyancy material body that provides buoyancy and a storage unit for storing the cable.

[0003] In existing buoyancy storage devices, the float body and the acoustic release device are often connected separately or with simple clamps, resulting in a loose overall structure. During the deep-sea diving and surfacing of the acoustic release device, when the fluid resistance / impact force on the acoustic release device is large, the relative position of the float body and the acoustic release device is difficult to control.

[0004] Therefore, a new buoyancy storage rope device needs to be designed. Utility Model Content

[0005] The purpose of this invention is to overcome at least one of the aforementioned problems in the prior art. It provides a buoyancy storage rope device and an acoustic release system for an acoustic release device, which facilitates a stable connection between the buoyancy material body and the acoustic release device.

[0006] The first aspect of the technical solution of this utility model is:

[0007] A buoyancy storage device for an acoustic release device includes a storage tank structure, a buoyancy body, and a locking assembly for connection with the acoustic release device.

[0008] Both the rope storage bucket structure and the float body have a sleeve structure that can be fitted onto the acoustic release device.

[0009] The locking assembly includes a first clamping ring and a second clamping ring, which are respectively clamped to both sides of the float body. The first clamping ring has a connection structure for connecting to the acoustic release device, and the second clamping ring is connected to the first clamping ring through an adjustable locking structure.

[0010] The float body is ring-shaped, and the inner ring structure of the float body forms the sleeve structure that can be fitted onto the acoustic release device.

[0011] In some embodiments, the adjustable locking structure includes a first screw, the two ends of which are respectively connected to the first clamping ring and the second clamping ring;

[0012] The first screw penetrates the float body, or the first screw is located on the outside of the float body.

[0013] In some embodiments, the two ends of the first screw pass through the first clamping ring and the second clamping ring respectively, and the two ends of the first screw are respectively provided with limiting structures; the limiting structures are used to abut against the first clamping ring or the second clamping ring, and an isolation member is clamped between the limiting structure and the corresponding first clamping ring or the second clamping ring.

[0014] In some embodiments, the bottom edge of the float body has an annular limiting protrusion, and the float body is connected to a rope;

[0015] The rope storage drum structure has a rope storage space for storing the rope;

[0016] The float body is connected to one end of the rope storage tank structure via the annular limiting protrusion.

[0017] In some embodiments, the rope storage bucket structure has an outer cylindrical wall, and the outer side wall of the outer cylindrical wall constitutes the outer side wall of the rope storage bucket structure.

[0018] The rope storage bucket structure also has an inner cylindrical wall located inside the outer cylindrical wall. A gap exists between the inner wall of the outer cylindrical wall and the outer wall of the inner cylindrical wall to form the rope storage space. The interior of the inner cylindrical wall forms a first channel for the acoustic release device to be inserted. The inner cylindrical wall forms the sleeve structure on the rope storage bucket structure.

[0019] The second clamping ring can be sleeved on the acoustic release device; when the float body and the rope storage bucket structure are sleeved on the acoustic release device, the acoustic release device is inserted into the first channel, there is a gap between the inner ring side of the second clamping ring and the outer wall of the acoustic release device, and the top end of the inner cylindrical wall is embedded in the inner ring of the second clamping ring.

[0020] In some embodiments, a connecting rod is provided at the bottom end of the first channel; the outer cylindrical wall and the bottom end wall of the inner cylindrical wall are connected by an annular bottom wall, the bottom end of the bottom wall having a radially extending first groove; one end of the first groove extending outward to the outer side of the outer cylindrical wall, and one end extending inward to the outer side of the bottom end wall of the inner cylindrical wall; the bottom end wall of the inner cylindrical wall has a partially mounting wall that closes the inner end of the first groove.

[0021] On the bottom wall, the two first grooves are respectively located on opposite sides of the bottom end wall of the inner cylindrical wall. The bottom end wall of the inner cylindrical wall has two partial mounting walls corresponding to the two first grooves. The connecting rod passes through the two partial mounting walls and is disposed in the first channel.

[0022] In some embodiments, a drainage hole is provided on the bottom wall, and / or, a first notch is provided at the top of the outer cylindrical wall for the rope to pass through.

[0023] The second aspect of the technical solution of this utility model is:

[0024] An acoustic release system includes an acoustic release device and a buoyancy storage rope device as described in the first aspect; the acoustic release device has a housing and a transducer module disposed at the top of the housing, the transducer module including a protective cage and a transducer body disposed within the protective cage; a first clamping ring is connected to the protective cage via the connecting structure.

[0025] In some embodiments, the protective cage includes a first flange seat disposed at the top of the cabin, and protective rings spaced apart at the top of the first flange seat; the first flange seat and the protective rings are connected by a plurality of protective pins, and the protective pins are spaced apart circumferentially; the transducer body is disposed at the top of the first flange seat;

[0026] The protective pin includes a retaining pin; the retaining pin is inserted into the top of the first flange seat from the top of the first flange seat; along the insertion direction of the retaining pin, the first clamping ring is at least partially located between the first flange seat and the retaining pin, the insertion end of the retaining pin has a stepped shaft structure, the stepped shaft structure has a shoulder for pressing the first clamping ring against the top of the first flange seat; the first clamping ring is provided with a mounting hole for the retaining pin to be inserted, and the connection structure includes the mounting hole.

[0027] This utility model provides a buoyancy cable storage device and an acoustic release system. The buoyancy cable body and the cable storage tank structure can be fitted around the outer periphery of the acoustic release device to form a nested structure, thus restricting the lateral displacement of the buoyancy cable body and the cable storage tank structure relative to the acoustic release device. After the buoyancy cable body, the cable storage tank structure, and the acoustic release device form a nested structure, the first clamping ring and the second clamping ring cooperate to clamp the two sides of the buoyancy cable body. The first clamping ring is fixedly connected to the acoustic release device through a connecting structure, thus restricting the longitudinal displacement of the buoyancy cable body relative to the acoustic release device, thereby facilitating a stable connection between the buoyancy cable body and the acoustic release device.

Therefore, they should not be construed as limitations on this utility model. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0052] The various specific technical features and embodiments described in the detailed embodiments can be combined in any suitable manner without contradiction. For example, different implementation methods can be formed by combining different specific technical features / embodiments. In order to avoid unnecessary repetition, the various possible combinations of the various specific technical features / embodiments in this utility model will not be described separately.

[0053] Firstly, such as Figures 1 to 5a As shown in the figure, an embodiment of the present invention provides a buoyancy storage device for an acoustic release device 100, comprising a storage tank structure 500, a float body 200, and a locking assembly for connecting to the acoustic release device 100; both the storage tank structure 500 and the float body 200 have a sleeve structure that can be fitted onto the acoustic release device 100; the locking assembly includes a first clamping ring 110 and a second clamping ring 120, the first clamping ring 110 and the second clamping ring 120 respectively clamping the two sides of the float body 200, and the first clamping ring 110 has a connection structure 112 for connecting to the acoustic release device 100 (for details on the connection structure 112, please refer to...). Figure 7a and Figure 7b The second clamping ring 120 is connected to the first clamping ring 110 via an adjustable locking structure (i.e., the first screw 130).

[0054] Thus, in this application, the float body 200 and the rope storage tank structure 500 can be fitted onto the acoustic release device 100 to form a nested structure with the acoustic release device 100, thereby restricting the lateral displacement of the float body 200 and the rope storage tank structure 500 relative to the acoustic release device 100.

[0055] Please see Figure 1 and Figure 2After the float body 200, the rope storage bucket structure 500, and the acoustic release device 100 form a nested structure, the first clamping ring 110 and the second clamping ring 120 cooperate to clamp the upper and lower sides of the float body 200 along the height direction of the acoustic release device 100 (the height direction of the acoustic release device 100 is...). Figure 1 The first clamping ring 110 is fixedly connected to the acoustic release device 100 through the connecting structure 112, which restricts the longitudinal displacement of the float body 200 relative to the acoustic release device 100, thereby facilitating a stable connection between the float body 200 and the acoustic release device 100.

[0056] Specifically, in this embodiment, both the first clamping ring 110 and the second clamping ring 120 are annular plates and can be sleeved on the acoustic release device 100. The float body 200 is annular, and the inner ring structure of the float body 200 forms the sleeve structure that can be sleeved on the acoustic release device 100. The annular shapes of the first clamping ring 110 and the second clamping ring 120 are matched with the annular cross-section of the float body 200.

[0057] Compared to the float body 200 in the prior art (which is usually a float connected to the acoustic release device 100 by a traction rope), the float body 200 in this application is installed on the acoustic release device 100 in a more stable manner, and the float body 200 and the acoustic release device 100 have a compact structure that is not easily loosened.

[0058] Understandably, when the float body 200 is installed on the acoustic release device 100, the first clamping ring 110 can be fixedly connected to the acoustic release device 100 through the connecting structure 112. In order to ensure that the relative position of the float body 200 and the first clamping ring 110 is stable, a second clamping ring 120 can be provided to be connected to the first clamping ring 110 through an adjustable locking structure. In this way, by moving the second clamping ring 120 on the adjustable locking structure and getting closer to the first clamping ring 110, the second clamping ring 120 can press the float body 200 against the first clamping ring 110, ensuring that the locking component clamps the float body 200.

[0059] Specifically, please refer to Figures 1 to 5a In this embodiment, the acoustic release device 100 includes a cylindrical chamber 150, and a transducer module 300 is disposed at the top of the chamber 150. When the buoyancy storage rope device is installed on the acoustic release device 100 in this embodiment, the buoyancy material body 200 is sleeved on the outer periphery of the chamber 150; the first clamping ring 110 is fixedly connected to the transducer module 300.

[0060] The adjustable locking structure includes a first screw 130, with its two ends connected to the first clamping ring 110 and the second clamping ring 120, respectively; in the first clamping ring 110 and the second clamping ring 120, the second clamping ring 120 is located at the bottom of the first clamping ring 110.

[0061] Thus, the first clamping ring 110 is fixedly connected to the entire acoustic release device 100 by the fixed connection to the transducer module 300; when the float body 200 is clamped by the locking component, the second clamping ring 120 can slide toward the first clamping ring 110 along the extension direction of the first screw 130, thereby sliding closer to the first clamping ring 110 along the height direction of the acoustic release device 100, pressing the float body 200 against the first clamping ring 110. It is understandable that the configuration of the transducer module 300 is a conventional technical means in the field of acoustic release device 100. Generally speaking, the acoustic transducer 100 is provided with a release module 400 for connecting to other devices and a communication connection release module 400. The transducer module 300 is used to receive valid acoustic signals to control the release module 400 to connect to or disconnect from other devices. The transducer module 300 is usually located at the top of the housing 150 of the acoustic release device 100, and the release module 400 is usually located at the bottom of the housing 150 of the acoustic release device 100.

[0062] Specifically, in this embodiment, four first screws 130 are provided, and all four first screws 130 penetrate the float body 200 to reliably fix the float body 200.

[0063] Alternatively, in other embodiments, multiple first screws 130 are provided, and each first screw 130 is circumferentially spaced on the outer side of the float body 200 to limit the lateral displacement of the float body 200. In this case, the first screws 130, the first clamping ring 110, and the second clamping ring 120 cooperate to form a protective structure for accommodating the float body 200.

[0064] Specifically, in this embodiment, when the float body 200 is fitted onto the acoustic release device 100, there is a gap between the second clamping ring 120 and the outer wall of the acoustic release device 100 (i.e., the outer wall of the cabin 150). That is, the second clamping ring 120 is annular, and its inner side is spaced from the outer side of the cabin 150. This not only facilitates the sliding of the second clamping ring 120, but also makes it less likely for the second clamping ring 120 to scrape against the outer wall of the cabin 150 when sliding.

[0065] Understandably, in some specific implementations, the inner cavity of the housing 150 of the acoustic release device 100 forms a closed cavity, and various electronic components required for the operation of the acoustic release device 100 are installed inside the housing 150. When the acoustic release device 100 is submerged in the ocean, the housing 150 typically needs to maintain the sealing of its inner cavity while withstanding the high pressure of seawater; if the housing 150 deforms under pressure, it may affect the sealing of the inner cavity of the housing 150. In this application, because there is a gap between the second clamping ring 120 and the outer wall of the housing 150 and they are not directly rigidly connected, the wall of the housing 150 is not easily deformed or worn due to the movement of the second clamping ring 120, which to a certain extent helps to ensure the sealing of the inner cavity of the housing 150 on the acoustic release device 100.

[0066] Specifically, in this embodiment, the float body 200 is made of pressure-resistant composite foam material and has a rigid outer shell, and the first clamping ring 110 and the second clamping ring 120 are made of aluminum alloy.

[0067] Specifically, the two ends of the first screw 130 pass through the first clamping ring 110 and the second clamping ring 120 respectively, and the two ends of the first screw 130 are respectively provided with limiting structures; the limiting structures are used to abut against the first clamping ring 110 or the second clamping ring 120, and a spacer 140 is provided between the limiting structure and the corresponding first clamping ring 110 or second clamping ring 120.

[0068] For more details, please refer to Figures 6 to 7b In this embodiment, a first nut 121 is threaded onto one end of the first screw 130 that passes through the second clamping ring 120. By screwing the first nut 121 into the first screw 130, the second clamping ring 120 can be pressed against the bottom side of the float body 200. The first nut 121 is a "limiting structure" on the first screw 130 corresponding to the second clamping ring 120.

[0069] A nut 111 is provided on one end of the first screw 130 that passes through the first clamping ring 110. The nut 111 is used to restrict the first clamping ring 110 from moving upward and disengaging from the first screw 130. When the first nut 121 is screwed into the first screw 130, the first nut 121 and the nut 111 can cooperate to abut against the first clamping ring 110 and the second clamping ring 120 on the top and bottom sides of the float body 200, respectively. In this embodiment, the nut 111 is the "limiting structure" on the first screw 130 corresponding to the first clamping ring 110.

[0070] Please see Figure 5dIn this embodiment, an annular washer-shaped spacer 140 is provided between the first nut 121 and the second clamping ring 120 to prevent direct contact between the first nut 121 and the second clamping ring 120. For example, in some implementations, the first nut 121 is made of metal, the second clamping ring 120 is made of aluminum alloy, and the spacer 140 is made of nylon insulation material. By providing the spacer 140 to prevent direct contact between the first nut 121 and the second clamping ring 120, electrochemical corrosion between the first nut 121 and the second clamping ring 120 can be avoided.

[0071] Please see Figure 5b In this embodiment, a spacer 140 is provided between the nut 111 and the first clamping ring 110, and the spacer 140 is in the form of a flanged bushing. The flanged bushing spacer 140 is used to prevent the nut 111 and the first clamping ring 110 from directly contacting each other. For example, in some implementations, the first screw 130 (and the nut 111 on it) is made of metal, the first clamping ring 110 is made of aluminum alloy, and the spacer 140 is made of nylon insulation material. The flanged bushing spacer 140 prevents the nut 111 and the first clamping ring 110 from directly contacting each other through its flange portion, which can prevent electrochemical corrosion between the nut 111 and the first clamping ring 110; the bushing sleeve portion of the spacer 140 can prevent the rod of the first screw 130 from directly contacting the first clamping ring 110.

[0072] It is understood that in this embodiment, the isolator 140 not only serves as insulation but also serves to distribute stress, that is, to prevent the first nut 121 from making hard contact with the second clamping ring 120 and to prevent the nut 111 from making hard contact with the first clamping ring 110.

[0073] Of course, in other embodiments, the first screw 130 may be threaded with a first nut 121 at both ends as a "limiting structure". By screwing in the two first nuts 121 at both ends of the first screw 130, the first clamping ring 110 and the second clamping ring 120 are respectively pressed against the top and bottom sides of the floating material body 200.

[0074] Please see Figure 5a , Figure 5c and Figure 9 In some embodiments, the bottom edge of the float body 200 has an annular limiting protrusion 210, and the bottom end of the float body 200 is connected to a rope 610; the rope storage bucket structure 500 has a rope storage space 530 for storing the rope 610.

[0075] When the float body 200 and the rope storage bucket structure 500 are fitted onto the acoustic release device 100, along the height direction of the acoustic release device 100, the rope storage bucket structure 500 is located at the bottom of the float body 200, and the float body 200 is fitted onto the outer side of the top of the rope storage bucket structure 500 through the annular limiting protrusion 210.

[0076] Thus, when the float body 200 and the rope storage bucket structure 500 are fitted onto the acoustic release device 100, the annular limiting protrusion 210 on the float body 200 and the top wall of the rope storage bucket structure 500 can form a mechanical limit. The float body 200 can provide radial support to the rope storage bucket structure 500 through the annular limiting protrusion 210, which is beneficial to the overall stability of the buoyancy rope storage device (on the acoustic release device 100).

[0077] It is understood that of the two ends of the rope 610, the first end is connected to the bottom end of the float body 200 (for example, the rope 610 can be connected to the end of the first screw 130 that passes through the bottom end of the float body 200), and the second end is used to connect to the rope storage tank structure 500 or external equipment (hereinafter referred to as marine equipment 600); in this embodiment, the second end of the rope 610 is connected to the marine equipment 600. It is understood that the marine equipment 600 can be a marine environmental monitoring device, a submersible platform system, etc., deployed on the seabed.

[0078] In one specific implementation, when the cable storage tank structure 500 is fitted onto the acoustic release device 100, the first end of the cable 610 is connected to the bottom end of the float body 200; the portion of the cable 610 closer to the second end is inserted into the cable storage space 530 on the cable storage tank structure 500; the portion of the cable 610 closer to the second end extends out of the cable storage space 530 and extends outside the cable storage tank structure 500; the second end of the cable 610 is fixedly connected to the marine equipment 600.

[0079] Understandably, please refer to Figure 5a , Figure 5c and Figure 9 On the acoustic release device 100, a release module 400 is provided at the bottom end of the cabin 150. The release module 400 is used for controllable clutch connection of the rope storage tank structure 500; that is, when the float body 200 and the rope storage tank structure 500 are sleeved on the acoustic release device 100, the acoustic release device 100 is connected to the rope storage tank structure 500 through the release module 400.

[0080] In one specific implementation, the float body 200 and the cable storage tank structure 500 are both fitted onto the acoustic release device 100; the acoustic release device 100 is connected to the cable storage tank structure 500 via a release module 400, and the cable storage tank structure 500 is connected to the marine equipment 600; the float body 200, the acoustic release device 100, the cable storage tank structure 500, and the marine equipment 600 are all submerged below the sea surface. Below the sea surface, the float body 200, connected to the acoustic release device 100, provides buoyancy for the acoustic release device 100 to rise, while the cable storage tank structure 500 (fixedly connected to the marine equipment 600) is connected to the acoustic release device 100 to restrict the acoustic release device 100 from rising.

[0081] In this scenario, when the transducer module 300 receives a valid acoustic signal, the transducer module 300 can drive the release module 400 to disengage from the rope storage tank structure 500, causing the acoustic release 100 to disengage from the rope storage tank structure 500, thereby allowing the acoustic release 100 to float upwards. Please refer to... Figure 9 At this point, the cable reservoir structure 500 and the marine equipment 600 are fixedly connected and remain on the seabed, while the float body 200 and the acoustic release device 100 rise to the surface. One end (upper end) of the rope 610 is connected to the float body 200, and the other end (lower end) of the rope 610 is connected to the marine equipment 600. Once on the surface, the acoustic release device 100 and the float body 200 are easily identifiable, and personnel can retrieve the marine equipment 600 and the cable reservoir structure 500 using the rope 610 connected to the float body 200.

[0082] Specifically, please refer to Figure 2 and Figure 5a In this embodiment, the rope storage bucket structure 500 has an outer cylindrical wall 510, the outer side of which constitutes the outer side wall of the rope storage bucket structure 500; the rope storage bucket structure 500 also has an inner cylindrical wall 520 located inside the outer cylindrical wall 510, and a gap is formed between the inner side wall of the outer cylindrical wall 510 and the outer side wall of the inner cylindrical wall 520 to form the rope storage space 530 (the cross-section of the rope storage space 530 is annular), and a first channel 521 for the acoustic release device 100 to be inserted is formed inside the inner cylindrical wall 520; the inner cylindrical wall 520 forms the sleeve structure on the rope storage bucket structure 500.

[0083] Please see Figure 5a and Figure 5dIn this application, when the float body 200 is fitted around the acoustic release device 100, the second clamping ring 120 can be simultaneously fitted around the acoustic release device 100. When the float body 200 and the rope storage bucket structure 500 are fitted around the acoustic release device 100, the acoustic release device 100 is inserted into the first channel 521, and there is a gap between the inner ring side of the second clamping ring 120 and the outer wall of the acoustic release device 100 (i.e., the outer wall of the cabin 150), and the top end of the inner cylindrical wall 520 is embedded in the inner ring of the second clamping ring 120. In this way, the top end of the inner cylindrical wall 520 can form a nested structure with the second clamping ring 120, which is beneficial to the stable setting of the rope storage bucket structure 500 and the float body 200 on the acoustic release device 100.

[0084] Understandably, please refer to Figure 5d In this embodiment, the top end of the inner cylindrical wall 520 can also be embedded in the inner ring of the float body 200; the float body 200 has a groove at the inner ring for the top end of the inner cylindrical wall 520 to be embedded.

[0085] Furthermore, the top end of the outer cylindrical wall 510 is provided with a first notch 511 for the rope 610 to pass through, so that the rope 610 can pass through the first notch 511 and be connected to the marine equipment 600. There may be two first notches 511 on the outer cylindrical wall 510, located on opposite sides of the outer cylindrical wall 510.

[0086] Understandably, in this application, the rope 610 is stacked in the rope storage space 530 using a folding and reciprocating method, rather than being spirally wound around the outer side of the inner cylindrical wall 520 within the rope storage space 530. Thus, when the acoustic release device 100 operates in a real marine environment, the release of the rope 610 is facilitated when the release module 400 detaches from the rope storage barrel structure 500 on the seabed, and the float body 200 and acoustic release device 100 rise to the surface.

[0087] Specifically, please refer to Figure 5a and Figure 8 In this embodiment, the bottom end of the first channel 521 is provided with a connecting rod 522 for the controllable clutch connection of the release module 400.

[0088] It is understood that in this embodiment, the release module 400 includes a controllable swing hook 410. The release module 400 is hooked to or detached from the connecting rod 522 by swinging the hook 410. When the acoustic release device 100 is connected to the rope storage tank structure 500 and submerged in the sea in the actual working environment of the ocean, the acoustic release device 100 is hooked to the connecting rod 522 by the hook 410 on the release module 400. After the transducer module 300 of the acoustic release device 100 receives a valid acoustic signal underwater, the transducer module 300 can control the release module 400 to swing the hook 410, thereby detaching the hook 410 from the connecting rod 522, and thus allowing the acoustic release device 100 to detach from the rope storage tank structure 500 and float to the surface. The arrangement of the hook 410, the arrangement of the connecting rod 522 on the rope storage tank structure 500, and the controllable clutch connection between the hook 410 and the connecting rod 522 are all conventional technical means in the field, and this application will not limit or elaborate on them here.

[0089] Specifically, please refer to Figure 8 In this embodiment, the outer cylindrical wall 510 and the bottom wall of the inner cylindrical wall 520 are connected by an annular bottom wall 540. The bottom end of the bottom wall 540 has a radially extending first groove 550. The outward end of the first groove 550 extends to the outside of the outer cylindrical wall 510, and the inward end of the first groove 550 extends to the outside of the bottom wall of the inner cylindrical wall 520. The bottom wall of the inner cylindrical wall 520 has a partial mounting wall 551 that closes the inner end of the first groove 550. On the bottom wall 540, two first grooves 550 are respectively located on opposite sides of the bottom wall of the inner cylindrical wall 520. The bottom wall of the inner cylindrical wall 520 has two partial mounting walls 551 corresponding to the two first grooves 550. The connecting rod 522 passes through the two partial mounting walls 551 and is disposed in the first channel 521.

[0090] In a specific implementation, when installing the connecting rod 522 into the rope storage tank structure 500, the connecting rod 522 can be inserted radially into the rope storage tank structure 500 from the outside, so that the connecting rod 522 is inserted into the two first grooves 550 in sequence and passes through the first channel 521.

[0091] In this application, the first groove 550 on the bottom wall 540 provides operating space for installing the connecting rod 522, making the installation process simpler. For example, after the connecting rod 522 passes through two partial mounting walls 551, an elastic washer and a locking nut 552 can be installed at the insertion end of the connecting rod 522, so that the insertion end of the connecting rod 522 can be locked on the outside of the corresponding partial mounting wall 551 (i.e., the side of the partial mounting wall 551 facing the inner groove of the corresponding first groove 550); the fixed end of the connecting rod 522 can have a rod cap and be locked on the outside of the corresponding partial mounting wall 551; the first groove 550 provides operating space for installing the elastic washer and locking nut 552 on the connecting rod 522.

[0092] In this embodiment, the connecting rod 522 is an M12 semi-threaded bolt, and the smooth part of the connecting rod 522 is located within the first channel 521. Furthermore, the bottom of the rope storage tank structure 500 is provided with multiple drainage holes 560. The number of drainage holes 560 can be six, eight, or other suitable quantities. Each drainage hole 560 is circumferentially spaced around the bottom end wall of the inner cylindrical wall 520 on the bottom wall 540. The drainage holes 560 are used to drain water accumulated in the rope storage space 530 when the rope storage tank structure 500 is pulled up in a marine environment.

[0093] Secondly, this application also provides an acoustic release system, including an acoustic release device 100 and a buoyancy storage rope device as described above; the acoustic release device 100 has a housing 150 and a transducer module 300 disposed at the top of the housing 150. It is understood that the acoustic release system is typically used in conjunction with marine equipment 600 in a marine environment; for example, the acoustic release device 100 and the buoyancy storage rope device on the acoustic release system can be interconnected, and the acoustic release device 100 can be connected to the marine equipment 600, thereby allowing the acoustic release system and the marine equipment 600 to sink together below the sea surface; after the acoustic release system and the marine equipment 600 sink together below the sea surface, when the acoustic release device 100 on the acoustic release system receives a valid acoustic signal through the transducer module 300, the acoustic release device 100 can detach from the marine equipment 600, and then float to the surface together with the buoyancy material body 200 in the buoyancy storage rope device, facilitating search operations.

[0094] Specifically, please refer to Figures 6 to 7b In this embodiment, the transducer module 300 includes a protective cage 310 and a transducer body 320, with the transducer body 320 disposed inside the protective cage 310; the first clamping ring 110 is connected to the protective cage 310 through the connecting structure 112 (that is, the first clamping ring 110 is fixedly connected to the entire acoustic release device 100 by fixing the transducer module 300).

[0095] Specifically, the protective cage 310 includes a first flange seat 311 disposed at the top of the cabin 150, and protective rings 312 disposed at intervals on the top of the first flange seat 311; the first flange seat 311 and the protective rings 312 are connected by multiple protective pins 313, and each of the protective pins 313 is circumferentially spaced; the transducer body 320 is disposed at the top of the first flange seat 311.

[0096] The protective pin 313 includes a fixing pin 3131; the fixing pin 3131 is inserted into the top of the first flange seat 311 from the top of the first flange seat 311; along the insertion direction of the fixing pin 3131 (i.e. Figure 6 (in the up-down direction), the first clamping ring 110 is at least partially located between the first flange seat 311 and the fixing pin 3131, the insertion end of the fixing pin 3131 has a stepped shaft structure 3133, the stepped shaft structure 3133 has a shoulder for pressing the first clamping ring 110 against the top of the first flange seat 311.

[0097] In this embodiment, there are six protective pins 313, four of which are fixed pins 3131. Among the four fixed pins 3131, two fixed pins 3131 are grouped together to divide each fixed pin 3131 into two groups. The two groups of fixed pins 3131 are respectively set on opposite sides of the transducer module 300 (i.e., on the top of the first flange seat 311).

[0098] The stepped shaft structure 3133 on the fixing pin 3131 has a progressively increasing diameter from the bottom to the top of the acoustic release device 100, thereby providing a shoulder that can press the first clamping ring 110 against the top of the first flange seat 311. Specifically, in this embodiment, the first clamping ring 110 is provided with a mounting hole for the fixing pin 3131 to be inserted, and the connecting structure 112 includes the mounting hole. The stepped shaft structure 3133 on the fixing pin 3131 passes through the mounting hole on the first clamping ring 110 to fix the first clamping ring 110.

[0099] With the stepped shaft structure 3133 on the fixing pin 3131, the connection between the first clamping ring 110 and the transducer module 300 does not require the use of welding methods commonly found in conventional technologies, or the use of additional screws for connection; thus, in this application, the connection method between the first clamping ring 110 and the transducer module 300 is simple.

[0100] Specifically, please refer to Figures 6 to 7bIn this embodiment, the top end of each fixing pin 3131 abuts against the bottom end of the protective ring 312 to support the protective ring 312. Multiple fixing pins 3132 (four sets of fixing pins 3131 and fixing pins 3132 in this embodiment) are inserted through the top end of the protective ring 312 corresponding to each fixing pin 3131. The insertion end of each fixing pin 3132 penetrates the protective ring 312 and is inserted into the top end of its corresponding fixing pin 3131, and is then fixedly connected to the top end of each fixing pin 3131 by threaded connection or riveting. The head of each fixing pin 3132 presses the protective ring 312 against the top end of each fixing pin 3131, thereby fixing the protective ring 312 and each fixing pin 3131; that is, the fixing pins 3132 and fixing pins 3131 together clamp the protective ring 312.

[0101] Specifically, in this embodiment, two of the six protective pins 313 are connecting pins 3134, which are different from the fixing pins 3131. The connecting pins 3134 pass through the top of the protective ring 312 and the bottom end (insertion end) of the connecting pins 3134 is inserted into the first flange seat 311, thereby being fixedly connected to the first flange seat 311. The top of the connecting pin 3134 has a pin cap; when the connecting pin 3134 is inserted into the first flange seat 311 and fixedly connected to the first flange seat 311, the pin cap of the connecting pin 3134 presses the entire structure of the protective ring 312 and each fixing pin 3131 against the top of the first flange seat 311. It can be understood that in this embodiment, a lifting lug 314 is also provided on the top of the protective ring 312. When the connecting pin 3134 passes through the protective ring 312, it also passes through the lifting lug 314. The pin cap of the connecting pin 3134 can also press the lifting lug 314 against the top of the protective ring 312.

[0102] Alternatively, the bottom end of each protective pin 313 may be threaded to the first flange seat 311, and the first flange seat 311 may be provided with threaded holes corresponding to each protective pin 313.

[0103] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
